Apparent treatment‐resistant hypertension (aTRH), defined as blood pressure (BP) that remains uncontrolled despite unconfirmed concurrent treatment with three antihypertensives, is associated with an increased risk of developing cardiovascular and renal complications compared with controlled hypertension. We aimed to identify the characteristics of aTRH patients with an elevated risk of major adverse cardiovascular events plus (MACE+; defined as stroke, myocardial infarction, or heart failure hospitalization) and end stage renal disease (ESRD). This retrospective cohort study included aTRH patients (BP ≥140/90 mmHg and taking ≥3 antihypertensives) from the United States–based Optum® de‐identified Electronic Health Record dataset and used machine learning models to identify risk factors of MACE+ or ESRD. Patients had claims for ≥3 antihypertensive classes within 30 days between January 1, 2015 and June 30, 2021, and two office BP measures recorded 1–90 days apart within 30 days to 11 months after the index regimen date. Of a total 18 797 070 patients identified with any hypertension, 71 100 patients had aTRH. During the study period (mean 25.5 months), 4944 (7.0%) patients had a MACE+ and 2403 (3.4%) developed ESRD. In total, 22 risk factors were included in the MACE+ model and 16 in the ESRD model, and most were significantly associated with study outcomes. The risk factors with the largest impact on MACE+ risk were congestive heart failure, stages 4 and 5 chronic kidney disease (CKD), age ≥80 years, and living in the Southern region of the United States. The risk factors with the largest impact on ESRD risk, other than pre‐existing CKD, were anemia, congestive heart failure, and type 2 diabetes. The overall study cohort had a 5‐year predicted MACE+ risk of 13.4%; this risk was increased in those in the top 50% and 25% high‐risk groups (21.2% and 29.5%, respectively). The overall study cohort had a predicted 5‐year risk of ESRD of 6.8%, which was increased in the top 50% and 25% high‐risk groups (10.9% and 17.1%, respectively). We conclude that risk models developed in our study can reliably identify patients with aTRH at risk of MACE+ and ESRD based on information available in electronic health records; such models may be used to identify aTRH patients at high risk of adverse outcomes who may benefit from novel treatment interventions.

Key Clinical Message: Microscopic polyangiitis is a rare autoimmune vasculitis, that could present with renal‐pulmonary symptoms, posing diagnostic challenges in patients with preexisting kidney disease. Timely diagnosis is crucial to improve patient outcomes. [ABSTRACT FROM AUTHOR]

Background/Aims: The aim of this study is to investigate the utility of clinical [age, gender, mean arterial pressure (MAP)] and laboratory parameters [eGFR, hemoglobin (Hgb), serum levels of creatinine, uric acid, albumin, proteinuria, hematuria] and also histopathological lesions (Oxford classification parameters, crescents, intensity and pattern of staining for C3, C1Q, IgA, IgG, IgM) as progression markers in patients with IgA Nephropathy (IgAN). Methods: A total of 111 IgAN patients with a follow-up period >1 year or who reached kidney failure [GFR category G5 chronic kidney disease (CKD)] <1 year were investigated. Primary endpoint was the development of kidney failure or eGFR decline ≥50% from the baseline. Kaplan-Meier and Cox proportional hazards analyses were performed. Results: Mean follow-up period was 33±29 months. Thirty-seven (33.3%) patients progressed to kidney failure and 4 (3.6%) patients developed eGFR decline ≥50% from the baseline after a median of 23 and 65 months, respectively. In multivariate Cox regression analysis, baseline levels of Hgb (HR:0.782, 95% CI 0.559-0.973, p=0.037), serum uric acid (HR:1.293, 95% CI 1.023-1.621, p=0.046), eGFR (HR:0.966, 95% CI 0.947-0.984, p=0.004) and intensity of C3 staining (HR:1.550, 95% CI 1.198-1.976, p=0.049) predicted primary endpoint. Serum uric acid level was associated independently with T score (β=0.303, p=0.005) in patients with eGFR>30 ml/min/m2. Conclusions: Hyperuricemia and the deposition of C3 are independent risk factors for IgAN progression. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to determine the risk factors associated with the failure of arteriovenous fistulae (AVF) maturation. Methods: This retrospective cohort study was conducted from January 2014 to December 2018 in Sultan Qaboos University Hospital, Muscat, Oman. Patients were followed-up 3 months after surgery, and their electronic medical records were accessed for demographic and clinical data. Univariate analysis was used to determine the risk factors associated with early AVF maturation and multivariant analysis was used to determine the predictive factors for AVF failure. Results: A total of 269 patients were included. Female gender was a significant factor affecting AVF maturity (P = 0.049), while age (P = 0.626), diabetes (P = 0.954), hypertension (P = 0.378), dyslipidaemia (P = 0.907), coronary artery disease (P = 0.576), cerebrovascular accident (P = 0.864), congestive heart failure (P = 0.685), previous central venous catheterisation (P = 0.05), fistula type (P = 0.863) and fistula site (P = 0.861) did not affect AVF maturation. Binary logistic regression showed that all the risk factors were insignificant. Failure of early AVF maturation affected 11.5% in the cohort. Conclusion: This study found that the proportion of early AVF maturation at our hospital is at par with that in the international literature. Failure of AVF maturation was significantly associated with the female gender. These findings can help nephrologists and vascular surgeons prognosticate AVF maturation rates. However, a larger study is needed for definitive conclusions. [ABSTRACT FROM AUTHOR]

Objective: We sought to evaluate the left atrial (LA) strain parameters of maintenance hemodialysis (MHD) patients before and after dialysis by two dimensional speckle tracking imaging (2D‐STI), and to explore the effect of volume load change on LA function. Methods: Seventy‐six patients with end stage renal disease (ESRD) on hemodialysis (HD) were enrolled in the study protocol. The median duration of dialysis was 24.0 (7.5, 59.5) months. In addition, 30 healthy subjects were selected as control group. Comprehensive echocardiography was performed immediately before and after hemodialysis to compare the changes in left atrial function. Results: Regarding LA strain parameters in patients of pre‐HD, the median (25th, 75th) LA reservoir, LA conduit, and LA contractile reserve were 28.0 (23.0, 34.5), −15.5 (−10.0, −21.5), −12.0 (−9.0, −16.0) respectively; the post‐HD were 26.0 (21.0, 29.0), −12.0 (−9, −15.5), −12.5 (−9, −15.5) respectively; and controls were 43.0 (36.0, 48.0), −24.0 (−18.0, −32.0), −17.0 (−15.0, −22.0) respectively. The left atrial strain parameters before HD were lower than controls, the differences were statistically significant, the p‐value were.000,.025, and.000, respectively. The reservoir function and conduit function of LA strain decreased after hemodialysis, the differences were statistically significant, the p‐value were.003 and.006, respectively. Regarding the contraction of LA, the differences between pre‐ and post‐HD were not statistically significant (p =.965). Conclusion: Hemodialysis removes excess water in human body, while LVGLS and Doppler parameters are greatly affected by reduced preload. New echocardiographic parameters, such as left atrial strain, can quantitatively evaluate the changes in left atrial function before and after hemodialysis in ESRD patients, which can provide valuable information for the overall cardiac evaluation in this specific population.

Introduction: Ocular manifestations of Haemodialysis (HD) are one of the important causes of morbidity in End-stage Renal Disease (ESRD) patients. According to studies, the incidence rate of glaucoma in the dialysis group was higher than that in the non dialysis group. Angle-closure glaucoma was found to be more common, which depends on anterior chamber morphology. Aim: To assess the effect of HD on Intraocular Pressure (IOP), Anterior Chamber Depth (ACD), and Lens Thickness (LT) in patients with ESRD. Materials and Methods: This was a single-centre crosssectional observational study conducted in the Department of Ophthalmology on 170 eyes of 87 patients undergoing HD for at least three months. The study was conducted between October 2020 and October 2022 at the Dialysis Centre of Bharati Vidyapeeth (DTU) Medical College and Hospital, Pune, Maharashtra, India. These patients underwent ophthalmological evaluation pre- and postdialysis. IOP, ACD, and LT were measured 30 minutes prior to and 30 minutes after the HD session. The paired t-test was used to compare differences in means, and a p-value of <0.05 was considered significant. Results: The mean age of the study participants was 57.63±11.95 years. There was a decrease in mean ACD by 0.08±0.29 mm (p=0.0001) and an increase in mean LT by 0.06±0.42 mm (p-value=0.0001) postdialysis. The changes in IOP were variable and not statistically significant (p=0.45). Conclusion: Postdialysis, a significant increase in LT was observed corresponding to a decrease in ACD. Although the change in IOP was variable, this change might be more significant in pre-existing narrow-angle patients undergoing dialysis. As a result, the present study underscores the urgency of refining screening protocols for HD patients to effectively address these identified ocular changes and associated risks.

Background: Foot and lower limb health complications are common among patients undergoing dialysis; but a summary of prevention and management evidence is not available. The aim of this scoping review was to summarise study characteristics and the nature of results regarding strategies to prevent and manage peripheral arterial disease (PAD), foot ulceration, amputation, associated infection and associated hospital admission in adults undergoing dialysis. Methods: MEDLINE, Embase, CINAHL and AMED databases were searched for longitudinal experimental and observational studies. Eligible studies included adults undergoing dialysis (≥10 dialysis patients, with separate results or ≥ 75% of the cohort). Any interventions relating to PAD, foot ulceration, amputation, associated infection, and associated hospital admission were included. Results: The review included 212 studies, of which 199 were observational (94%) and 13 were experimental (6%). Sixteen studies (8%) addressed the prevention of foot and lower limb health complications, 43 (20%) addressed management, and 153 (72%) addressed both. The main intervention type in each study was surgery (n = 159, 75%), care from one or more health professionals (n = 13, 6%), screening by a health professional (n = 10, 5%), medication (n = 9, 4%) and rehabilitation (n = 5, 2%). No studies were identified where exercise, offloading or education were the main intervention. Results for PAD were reported in 137 (65%) studies, foot ulceration in 54 (25%), amputation in 171 (81%), infection in 7 (3%), and admission in 26 studies (12%). Results for more than one foot or lower limb outcome were reported in 141 studies (67%), with each study reporting on average two outcomes. Results varied and spanned positive, negative, and neutral outcomes following intervention. Conclusions: Identified studies frequently aimed to both prevent and manage foot and lower limb health complications. A variety of interventions were identified and studies often reported results for more than one foot or lower limb health outcome. Findings from this review can be used to guide future research, with a goal to support improved patient outcomes. [ABSTRACT FROM AUTHOR]

End stage renal disease (ESRD) patients on renal replacement therapy (RRT) have an increased risk of morbidity and mortality due to healthcare associated infections (HCAIs). The aim of this study is to determine the prevalence, microbial etiology, and risk factors associated with HCAIs among ESRD patients on RRT. A multicenter, retrospective study was conducted from June to December 2019. ESRD patients with minimum of 6 months on RRT were included, while pregnant patients and patients <18 years were excluded. To reduce the risk of selection bias, all patients were randomly selected using a simple random sampling technique. The prevalence showing the proportion of patients that acquired HCAI since the initiation of dialysis until 2019 was calculated using the European patients' academy (EUPATI) formula. Risk factors were assessed using univariate and multivariate regression analysis. The prevalence of HCAI among ESRD patients was 174/400 (43.5%). Catheter related bloodstream infection (CRBSI) was the most common infection [64(36.8%)], followed by peritonitis [45(25.8%)] and pneumonia [37(21.2%)]. Out of 382 total pathogens identified, 204 (53.4%) were Gram positive and 162 (42.4%) were Gram negative. Both methicillin sensitive staphylococcus aureus (MSSA) and methicillin resistant staphylococcus aureus (MRSA) showed statistically significant associations (p<0.05) with CRBSI. Use of multiple accesses, increased blood sugar levels, low serum sodium levels and higher CRP concentration increased the occurrence of HCAIs. The burden of HCAIs among the patients undergoing RRT is high. Preventive strategies and optimum empirical therapy of antibiotics should be used to reduce the risk of these infections among ESRD patients. [ABSTRACT FROM AUTHOR]

Objective To investigate the attitudes and influencing factors of transplantation-related populations towards kidney xenotransplantation. Methods From June 2022 to January 2023, stratified random sampling was performed from patients awaiting kidney transplantation, patients after kidney transplantation, patients' relatives and medical students. Four hundred subjects were collected from each population and 1600 subjects were investigated using a self-designed questionnaire. Baseline data of the respondents, their attitudes towards kidney xenotransplantation and the reasons of rejecting kidney xenotransplantation were analyzed. The influencing factors of attitudes towards kidney xenotransplantation were also identified. Results A total of 1 493 valid questionnaires were collected, and the questionnaire retrieval rate was 93.31%. About 93.10% of the respondents accepted allogeneic kidney transplantation, and 66.78% had heard of kidney xenotransplantation. Seven hundred and ninety-five respondents suggested that they could accept kidney xenotransplantation "when kidney xenotransplantation and allogeneic kidney transplantation yielded the same results and risks". Six hundred and ninety-eight respondents indicated that they were "unable" or "uncertain" whether they could accept kidney xenotransplantation (χ² =16.409, P=0.001). Among these 698 respondents, the proportion of them who were willing to accept kidney xenotransplantation when they did not meet the conditions of allogeneic kidney transplantation was 10.9%. About 35.8% of respondents were willing to accept kidney xenotransplantation if it yielded less risk and better prognosis compared with allogeneic kidney transplantation. If the time of awaiting kidney xenotransplantation was shorter than that of allogeneic kidney transplantation, 21.2% were willing to accept kidney xenotransplantation. If the cost of kidney xenotransplantation was less than that of allogeneic kidney transplantation, 24.5% of them were willing to accept kidney xenotransplantation. The main reasons of rejecting kidney xenotransplantation included surgical risk and other unknown risks. Multivariate analysis showed that respondents residing in cities and towns for a long period of time, those who accept allogeneic kidney transplantation and those who have heard of kidney xenotransplantation showed more positive attitudes towards kidney xenotransplantation. Conclusions Different transplantation-related populations have different attitudes towards kidney xenotransplantation, and the overall attitudes are positive. Active promotion of kidney xenotransplantation research and carrying out relevant popular science education contribute to improving public attitudes towards the acceptance of kidney xenotransplantation.

Reliable models of renal failure in large animals are critical to the successful translation of the next generation of renal replacement therapies (RRT) into humans. While models exist for the induction of renal failure, none are optimized for the implantation of devices to the retroperitoneal vasculature. We successfully piloted an embolization-to-implantation protocol enabling the first implant of a silicon nanopore membrane hemodialyzer (SNMHD) in a swine renal failure model. Renal arterial embolization is a non-invasive approach to near-total nephrectomy that preserves retroperitoneal anatomy for device implants. Silicon nanopore membranes (SNM) are efficient blood-compatible membranes that enable novel approaches to RRT. Yucatan minipigs underwent staged bilateral renal arterial embolization to induce renal failure, managed by intermittent hemodialysis. A small-scale arteriovenous SNMHD prototype was implanted into the retroperitoneum. Dialysate catheters were tunneled externally for connection to a dialysate recirculation pump. SNMHD clearance was determined by intermittent sampling of recirculating dialysate. Creatinine and urea clearance through the SNMHD were 76–105 mL/min/m2 and 140–165 mL/min/m2, respectively, without albumin leakage. Normalized creatinine and urea clearance measured in the SNMHD may translate to a fully implantable clinical-scale device. This pilot study establishes a path toward therapeutic testing of the clinical-scale SNMHD and other implantable RRT devices. [ABSTRACT FROM AUTHOR]

Background: Autogenous Arterivenous (AV) access is the preferred choice for hemodialysis access in chronic kidney patients. Cimino fistulas are currently accepted as the best mode of vascular access for hemodialysis. The present study was planned to look for the presence of on table bruit and thrill and to know the postoperative outcome and patency. Material and Methods: This single center, prospective study was done in the department of vascular surgery at SMC, from January 2020 - January-2021. Dominance of hand was noted, and preference was given to non- dominant hand. Physical examination of the arterial system along with venous system was done. Preoperative color Doppler of upper limb veins and arteries was done in all the patients. Results: In study of 291 AV access, there were 161(55.3%) AV access which were successfully used for hemodialysis and 83(28.5%) were not. Arterial diameters was significantly found to be higher in those patients with patent AVFs. Conclusion: Creating and maintaining an autogenous AV access for hemodialysis is a complex process subject to patient specific characteristics and surgical expertise. This study suggests that patency rates and functional outcomes of dialysis access procedures are better in patients who are non-smokers, without comorbidities, without previous H/O AVF failure.

Introduction: Nutritional status is compromised in End-Stage Renal Disease (ESRD) patients on dialysis. In order to predict the clinical outcomes of these patients, the diagnosis of nutritional status becomes extremely important. However, data related to parameters assessing nutritional status are limited. Aim: The aim of this study was to assess the nutritional status of dialysis patients with ESRD at the renal care unit of a tertiary care hospital. Materials and Methods: A cross-sectional study was conducted at the renal care unit of a tertiary care hospital from January 2016 to July 2016. Fifty individuals were divided into two groups: 30 stable ESRD patients on Haemodialysis (HD) and 20 stable ESRD patients on Continuous Ambulatory Peritoneal Dialysis (CAPD). Data were collected using a questionnaire regarding nutritional assessment, which comprised medical history, food intake history, anthropometry, biochemical investigations, and Subjective Global Assessment (SGA). Based on the SGA analysis of nutritional status, the patients were divided into Categories A, B, and C. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 22.0. Results: A total of 50 subjects were included in the final analysis - 30 patients in the renal dialysis group and 20 patients in the CAPD group. Body Mass Index (BMI) was significantly higher in the HD group (21.78±2.86 kg/m²) than in the CAPD group (20.87±2.63 kg/m²). In the HD group, the majority were in Category B (60%). In the CAPD group, the majority were in Category B (70%). The mean anthropometric measurements were significantly higher in Category A, followed by B and C (p<0.001). There was no significant difference across groups in biochemical parameters, except for serum albumin levels, which were significant. Serum albumin levels were highest in Category A, followed by Category B, and Category C in reverse for S. Prealbumin (mg/dl). Conclusion: There is a significant number of ESRD patients who have malnutrition as an additional burden. These results suggest that low BMI and low calorie intake are harmful to ESRD patients on HD, causing severe malnutrition. Optimal calorie intake could reduce malnutrition in these patients.

Peritoneal dialysis (PD) is one of the options for renal replacement therapy (RRT) in the end stage renal disease (ESRD) patients. Compared to hemodialysis (HD), patients on PD experience a greater sense of well-being, an improved steady state in terms of extracellular fluid volume shifts and hemodynamics and it is preferred method for patients with problematic vascular access, bleeding tendencies, heart failure and elderly patients. In order to perform PD, a tunneled catheter should be placed through the abdominal wall and into peritoneal space, with positioning of the catheter within the most dependent portion of pelvis. Currently, there are several techniques available for PD catheter placement: open surgery, laparoscopic and percutaneous. We present for the first time in our country a case of 65 year old male patient to whom percutaneous onsite insertion of peritoneal catheter was performed. The idea is to emphasize that sometimes this should be a method of choice for RRT, especially in patients where general anesthesia should be avoid. Compared to other methods, percutaneous insertion is a simple procedure with no need for general anesthesia, and the benefits of quick recovery, earlier ambulation, and less delay in catheter placement.

Chronic kidney disease (CKD) is a worldwide public health problem related to adverse results of end-stage renal disease (ESRD), kidney failure, cardiovascular disease (CVD), and premature death. The study is aimed to investigate the knowledge, attitude, and practice toward the prevention and early detection of chronic kidney disease. Two ordinal variables and one nominal response variable with 20 predictor variables were independently fitted. Ordinal multicategories , such as proportional odds, continuation ratio, and partial proportional models for attitude and practice, whereas the baseline multicategory logit model for knowledge was fitted. The findings implied that some predictors have a significant effect on attitude, whereas other covariates have a significant effect on practice. Moreover, as there are two independent logit models for the nominal response, in the first logit model Monthly income and Diabetes2, whereas in the second logit model, Smo_R_CKD3 and Diabetes2 have a significant effect on knowledge. In conclusion, more educated ones have more knowledge and attitude toward the prevention and early detection of chronic kidney disease, also more likely to perform preventive and early detecting practices. People are inadequately informed on the prevention and early detection of CKD, especially those who are with low income, are at risk of developing CKD and its complications. [ABSTRACT FROM AUTHOR]

Objective To investigate whether adding renal histological score（MEST-C）to the Kidney Failure Risk Equation（KFRE）could improve predicting the risk of progression in advanced IgA nephropathy. Methods This was a prospective cohort study in which 205 patients with advanced IgA nephropathy［15 ~ 59 mL/（min·m²）］were enrolled and followed up to 2 years. The timepoint of renal biopsy was defined as baseline. The 4-variable/8-variable KFRE was used to estimate 2-year risk of progression to end stage renal disease（ESRD, defined as need for receiving maintenance dialysis or renal transplantation）. AUCs were calculated to evaluate the performance of risk prediction using KFRE and MEST-C alone or in combination. Risk classification for progression to ESRD was assessed by net reclassification index（NRI）and integrate discrimination index（IDI）. Results Among 205 patients with advanced IgA nephropathy, 38（18.5%）progressed to ESRD within 2 years of follow up. The 4-variable KFRE predicted the progression of advanced IgA nephropathy with an AUC of 0.81（95%CI：0.73 ~ 0.89）, while the 8-variable KFRE with an AUC of 0.79（95%CI：0.71-0.87）, the MEST-C with an AUC of 0.74 （95%CI：0.64 ~ 0.83）. Adding MEST-C to the 4-variable KFRE produced an overall AUC of 0.85（95%CI：0.78 ~ 0.91）and significant improvement for risk classification for ESRD（NRI, 0.47 and IDI 0.05）. Conclusion Adding renal histological score to the Kidney Failure Risk Equation improved risk prediction and reclassification of progression to ESRD in patients with advanced IgA nephropathy.

Polycystic kidney disease (PKD) is one of the most common hereditary kidney diseases, which is characterized by progressive cyst growth and secondary hypertension. In addition to cystogenesis and renal abnormalities, patients with PKD can develop vascular abnormalities and cardiovascular complications. Progressive cyst growth substantially alters renal structure and culminates into end-stage renal disease. There remains no cure beyond renal transplantation, and treatment options remain largely limited to chronic renal replacement therapy. In addition to end-stage renal disease, patients with PKD also present with hypertension and cardiovascular disease, yet the timing and interactions between the cardiovascular and renal effects of PKD progression are understudied. Here, we review the vascular dysfunction found in clinical and preclinical models of PKD, including the clinical manifestations and relationship to hypertension, stroke, and related cardiovascular diseases. Finally, our discussion also highlights the critical questions and emerging areas in vascular research in PKD. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to describe the clinical features of AAV and identify possible risk factors for end-stage renal disease (ESRD) and mortality in AAV based on the experience of a single center in China. Methods: A prospective cohort study of AAV was conducted based on data acquired by the Chinese Rheumatism Data Center (CRDC). The cohort involved 140 patients diagnosed with AAV in the Second Affiliated Hospital of Nanchang University from January 2013 to April 2022. Clinical characteristics and prognostic data were prospectively collected. The patients were divided into an ESRD group and a non-ESRD group, a death group and a survival group, Then, univariate and multivariate COX regression models were used to determine the risk factors associated with ESRD and mortality by AAV. Results: Multivariate Cox regression results showed that high initial serum creatinine (hazard ratio (HR) = 1.001, 95% confidence interval (CI): 1.000–1.002, P = 0.024), high initial Birmingham vasculitis activity score (BVAS) (HR = 1.081, 95% CI: 1.027–1.138, P = 0.003), and the need for dialysis treatment (HR = 4.918, 95% CI: 1.727–14.000, P = 0.003) were independent risk factors for the progression of ESRD in AAV patients. Multivariate Cox regression results showed that alveolar hemorrhage (HR = 3.846, 95% CI: 1.235–11.973, P = 0.020), interstitial lung disease (HR = 4.818, 95% CI: 1.788–12.982, P = 0.002), and low initial estimated glomerular filtration rate (EGFR) (HR = 0.981, 95% CI: 0.968–0.995, P = 0.009) were independent risk factors for the prediction of death in AAV patients. Conclusion: These findings suggest that high initial serum creatinine, a high initial BVAS score, and the need for dialysis were independent risk factors for the progression of ESRD in AAV patients. Alveolar hemorrhage, interstitial lung disease, and low initial EGFR were independent risk factors for death. Key Points • The risk factors for ESRD in AAV determined in this study are high initial serum creatinine, a high initial BVAS score, and the need for dialysis. • The risk factors for mortality in AAV are alveolar hemorrhage, interstitial lung disease, and low initial EGFR.

Background: We aimed to determine the effects of systemic therapy with autologous adipose tissue derived mesenchymal stem cells (AD-MSCs) on different parameters of peritoneal function and inflammation in peritoneal dialysis (PD) patients. Methods: We enrolled nine PD patients with ultrafiltration failure (UFF). Patients received 1.2 ± 0.1 x 106 cell/kg of AD-MSCs via cubital vein and were then followed for six months at time points of baseline, 3, 6, 12, 16 and 24 weeks after infusion. UNIPET was performed for assessment of peritoneal characteristics at baseline and weeks 12 and 24. Systemic and peritoneal levels of tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), IL-2 and CA125 (by ELISA) and gene expression levels of transforming growth factor beta (TGF-β), smooth muscle actin (α-SMA) and fibroblast-specific protein-1 (FSP-1) in PD effluent derived cells (by quantitative real-time PCR) were measured at baseline and weeks 3, 6, 12, 16 and 24. Results: Slight improvement was observed in the following UF capacity indices: free water transport (FWT, 32%), ultrafiltration - small pore (UFSP, 18%), ultrafiltration total (UFT, 25%), osmotic conductance to glucose (OCG, 25%), D/P creatinine (0.75 to 0.70), and Dt/D0 glucose (0.23 to 0.26). There was a slight increase in systemic and peritoneal levels of CA125 and a slight decrease in gene expression levels of TGF-β, α-SMA and FSP-1 that was more prominent at week 12 and vanished by the end of the study. Conclusion: Our results for the first time showed the potential of MSCs for treatment of peritoneal damage in a clinical trial. Our results could be regarded as hypothesis suggestion and will need confirmation in future studies. [ABSTRACT FROM AUTHOR]

Introduction: High-flux hemodialysis membranes may modulate the cytokine storm of SARS-CoV-2, but their impact on chronic hemodialysis (CHD) patients is unknown. The aim of the study was the evaluation of asymmetric cellulose triacetate (ATA) and polymethylmethacrylate (PMMA) dialyzers on inflammatory markers and clinical outcomes in CHD patients with SARS-CoV-2. Methods: A prospective, observational study on CHD patients with SARS-CoV-2 was carried out. Patients were enrolled from March 2020 to May 2021. Pre- and postdialysis C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) were determined at each session. Patients who underwent on-line hemodiafiltration (OLHDF) with a PMMA dialyzer were compared with those treated with OLHDF with a ATA dialyzer. The primary endpoint was the differences in the reduction ratio per session (RR) of CRP, PCT, IL-6, and IL-6 RR >25%. Results: We consecutively enrolled 74 CHD patients with COVID-19, 48 were treated with ATA membrane, and 26 with PMMA. Median IL-6 RR was higher in the ATA group compared to PMMA (17.08%, IQR −9.0 to 40.0 vs. 2.95%, IQR −34.63 to 27.32). Median CRP RR was 7.77% (IQR 2.47–13.77) in the ATA group versus 4.8% (IQR −2.65 to 11.38) in the PMMA group (p = 0.0017). Median PCT-RR% was 77.38% (IQR 70.92–82.97) in ATA group versus 54.59% (IQR 42.62–63.16) in the PMMA group (p < 0.0001). A multiple logistic regression analysis with IL-6 RR >25% as the outcome including the membrane employed, pre-dialysis IL-6, CRP, PCT, and ferritin showed that ATA led to a higher probability to reach the outcome (OR 1.891, 95% CI 1.273–2.840, p = 0.0018) while higher CRP favors the risk of lower IL-6 RR values (OR 0.910, 95% CI 0.868–0.949, p ≤ 0.0001). Conclusions: In SARS-CoV-2 CHD patients treated with OLHDF, ATA showed a better anti-inflammatory profile, regarding IL-6 RR, compared to PMMA. [ABSTRACT FROM AUTHOR]

We investigated if elevated cardiac troponin I (cTnI) serum levels before non-cardiac surgery were predictors of postoperative cardiac events in patients with end stage renal disease (ESRD) undergoing dialysis. In total, 703 consecutive patients with ESRD undergoing dialysis who underwent non-cardiac surgery were enrolled. Preoperative cTnI serum levels were measured at least once in all patients. The primary endpoint was defined as a composite of cardiac death, myocardial infarction (MI), and pulmonary edema during hospitalization or within 30 days after surgery in patients with a hospitalization longer than 30 days after surgery. Postoperative cardiac events occurred in 48 (6.8%) out of 703 patients (cardiac death 1, MI 18, and pulmonary edema 33). Diabetes mellitus (DM), previous ischemic heart disease, and congestive heart failure were more common in patients with postoperative cardiac events. Peak cTnI serum levels were higher in patients with postoperative cardiac event (180 ± 420 ng/L vs. 80 ± 190 ng/L, p = 0.008), and also elevated peak cTnI levels > 45 ng/L were more common in patients with postoperative cardiac events (66.8% vs. 30.5%, p < 0.001). Multivariate logistic regression analysis showed that DM (odds ratio [OR] 2.509, 95% confidence interval [CI] 1.178–5.345, p = 0.017) and serum peak cTnI levels ≥ 45 ng/L (OR 3.167, 95% CI 1.557–6.444, p = 0.001) were independent predictors for the primary outcome of cardiac death/MI/pulmonary edema. Moreover, cTnI levels ≥ 45 ng/L had an incremental prognostic value to the revised cardiac risk index (RCRI) (Chi-square = 23, p < 0.001), and to the combined RCRI and left ventricular ejection fraction (Chi-square = 12, p = 0.001). Elevated preoperative cTnI levels are predictors of postoperative cardiac events including cardiac death, MI, and pulmonary edema in patients with ESRD undergoing non-cardiac surgery.

Purpose Chronic kidney disease is highly prevalent in the general population and can progress to end-stage renal disease (ESRD). The purpose of this pilot study was to assess dental hygiene and dental therapy students' knowledge, attitudes, and perceptions towards ESRD and evaluate the feasibility of a larger scale study. Methods A convenience sample (n=59) of dental hygiene (DH) and dual degree DH/dental therapy students were invited to participate in an electronic survey for the pilot study. The investigator designed survey consisted of a total of 37 items: demographics (4), perceived knowledge, confidence, importance and attitudes (14), knowledge of chronic kidney disease (18). The knowledge questions were adapted from the Chronic Kidney Disease Self-Management Knowledge Tool (CKD-SMKT) with permission. Descriptive statistics and the non-parametric two-sample Wilcoxon rank sum test were used to analyze the data. Results Twenty-five participants completed the survey for a 42% response rate. Fewer than half (36%) perceived having some knowledge regarding ESRD, its oral manifestations (28%) and mental health implications (12%). The importance of managing oral health for ESRD was rated by most respondents as "very important" or "extremely important" (76%). Respondent attitudes indicated high interest (68%) regarding employment in hospital settings to care for individuals with ESRD. Knowledge scores from the CKD-SMKT were low in the categories of general knowledge of ESRD and dental hygiene care modifications for individuals with ESRD. Conclusion Results of this pilot study indicate that using a validated instrument on a national sample is feasible to determine the knowledge, attitudes and perceptions of dental hygiene students regarding ESRD. Future research should include knowledge and awareness of hypertension, diabetes, and the role that management of chronic kidney disease plays in the prevention of ESRD. [ABSTRACT FROM AUTHOR]

Fabry disease is an X-linked lysosomal storage disease, second in prevalence after Gaucher disease. The onset of symptoms occurs in childhood or adolescence with palmo-plantar burning pains, hypo hidrosis, angiokeratomas, and corneal deposits. In the absence of diagnosis and treatment, the disease will progress to the late phase, characterized by progressive cardiac, cerebral and renal damage, and possible death. We present the case of an 11-year-old male boy who was transferred to the Pediatric Nephrology Department for palmo-plantar burning pain and end stage renal disease. Following the evaluations for the etiology of end stage renal disease we excluded the vasculitis, the neurologic diseases, extrapulmonary tuberculosis. Because of suggestive aspect at CT scan and lack of etiologic diagnosis of renal insufficiency we performed lymph node and kidney biopsy, with a surprising result for storage disease. The specific investigation confirmed the diagnosis. [ABSTRACT FROM AUTHOR]

Background: Children with chronic renal disease can experience heart difficulties as a result of their condition. Objective: To evaluation of cardiac complications using Doppler tissue imaging among Children with end-stage renal disease. Subject and Methods: This study was conducted on 40 children with chronic renal failure (17 male and 23 female) their ages ranged from 8 years to 17 years attending the Nephrology Unit of the Pediatric Hospital Zagazig University. All children were subjected to thorough history taking, complete detailed clinical examination, and laboratory investigations. All cases and control were assessed by tissue Doppler velocity and strain imaging before and after dialysis. Results: Tissue Doppler Imaging (TDI) assessment of systolic functions using lateral and septal mitral velocity (S) in cases is decreased significantly in predialysis cases more than control but did not show significant change after dialysis, also septal S of tricuspid is reduced significantly in cases predialysis than control but did not show significant change after dialysis. TDI assessment of septal mitral & tricuspid E' &E'/A' showed a significant reduction in predialysis cases more than control but did not show any change after dialysis, also lateral mitral &tricuspid E'&E'/A' is decreased significantly in cases more than control but showed a significant decrease after dialysis. Conclusion: children with chronic renal failure (CRF) have significant cardiac abnormalities, TDI is a superior diagnostic method than conventional echocardiography in the diagnosis of systolic dysfunction as in our cases that appeared normal by conventional echocardiography. Also, TDI is less load-dependent in septal mitral & tricuspid E'&E'/A'. [ABSTRACT FROM AUTHOR]

Background: Children with chronic renal failure have an increased risk of mortality due to cardiovascular problems. Objective: To evaluation of cardiac complications using conventional echocardiography among children with end stage renal disease. Subject and Methods: This study was conducted on 40 children with chronic renal failure (17 males and 23 females), their age ranged from 8 years to 17 years, attending the Nephrology Unit of the Pediatric Hospital Zagazig University. All children were subjected to thorough history taking, complete detailed clinical examination and laboratory investigations. All cases and control were assessed by conventional echocardiography. Results: using mitral and tricuspid inflow velocities peak early velocity (E), peak late velocity (A), E/A ratio, we found significant decreased E/A ratio in our cases predialysis than control group of both mitral and tricuspid inflow velocities; the E/A ratio of the mitral and tricuspid valves dropped considerably following dialysis, which has been linked to diminished compliance of the ventricle due to hypertrophy. Myocardial performance index (MPI) assessing global systolic and diastolic functions of both RV and LV showed statistically significant increased values in cases more than control but did not show significant difference after dialysis. Conclusion: Major cardiac abnormalities are present in children with chronic renal failure (CRF), and they likely contribute to the high cardiovascular death rate seen in this population.

Background: In most cases, hypothyroidism is not linked to kidney disease. However, hypothyroidism has been shown to hasten the development of chronic kidney disease (CKD). Objective: The aim of the current study is to evaluate thyroid abnormalities in patients with end stage renal disease (ESRD) in a sample of Egyptian populations. Patients and Methods: A case control study was conducted on 70 Egyptian patients selected from the Nephrology Department in Theodor Bilharz Research Institute. Participants were divided into 2 groups; Group 1 included 40 patients with ESRD, with eGFR <15 mL/min, with no history of thyroid disease or receiving any thyroid medications. Group 2 included 30 health subjects, age and sex matched, with normal renal function, with no history of thyroid disease or receiving any thyroid medications. All subjects underwent full thyroid profile, and estimated GFR. Results: Symptoms of thyroid dysfunction were more frequent in ESRD group; statistically significant only in muscle weakness. TSH was statistically significantly higher in Group 1 cases with hypothyroidism. Thyroglobulin autoantibodies (TgAbs) were statistically significantly higher in cases with hypothyroidism. Antimicrosomal antibodies recorded only in hypothyroid cases. Free T3, TSH, TgAbs and thyroid volume had perfect diagnostic performance in diagnosing hypothyroidism among ESRD group. Conclusion: Frequency of hypothyroidism was higher in ESRD patients compared to the control group. Thus, it is important to keep monitoring thyroid functions in patients with advanced renal impairment that may enhance quality of life. [ABSTRACT FROM AUTHOR]

Introduction: Chronic inflammation is one of the underlying causes of cardiovascular disease which is commonly seen in patients with chronic kidney disease (CKD) and especially in end-stage renal disease (ESRD), as well as the patients on stable dialysis. Hemodialysis patients suffer from high mortality due to cardiovascular diseases. Objectives: Therefore, the present study aimed to evaluate the effect of atorvastatin and aspirin on C-reactive protein (CRP) concentration in hemodialysis patients and compare the effect of these two drugs on CRP concentration in these patients. Patients and Methods: In this descriptive-analytical study, the dialysis patients who had been on dialysis for more than four months were selected through medical records (N=75). Serum CRP was checked and those who had positive CRP entered in the analysis (n=20). Ten patients had been used atorvastatin at a dose of 20 mg daily and the other 10 patients received aspirin at a dose of 80 mg daily for two months. Serum CRP concentration was measured in all patients at the end of these two months. Results: The mean age of the patients was 65.6 years and the mean number of years on dialysis was three years. In addition, 65% of patients were male and 35% were female. The only significant relationship was between the effect of atorvastatin and CRP concentration and the effect of aspirin on CRP concentration while no statistically significant relationship was found between the two groups of aspirin and atorvastatin in terms of serum CRP value after the intervention. Conclusion: The results indicated that the effect of aspirin and atorvastatin on CRP concentration was positive in hemodialysis patients and reduced the serum level of CRP, indicating the anti-inflammatory role of these two drugs in hemodialysis patients. It should be noted that drug preference was not determined in the present study. [ABSTRACT FROM AUTHOR]

Background and Aim: This study aims to evaluate the clinical and histopathological profile in children with crescentic glomerulonephritis (CGN) and determine the predictors of renal outcome. Methods: In this retrospective study, we reviewed all native kidney biopsies performed in patients <18 years over 9 years (2011-2019). Individuals with ≥20% crescents with follow-up for at least 1 year were enrolled. Results: This study included 34 patients. The most common variety was immune-complex glomerulonephritis (GN) (type II CGN) (n=21; 62%), including patients with Henoch- Schonlein purpura (n=6), lupus nephritis (n=6), post-infectious GN (n=3), C3GN (n=3), and dense deposit disease (n=3). The second most common was pauci-immune GN (type III CGN; n=12; 35%) followed by anti-glomerular basement membrane disease (type I CGN; n=1; 3%). Hypertension (88%), hematuria (84.2%), and oliguria (64%) were the most common presenting features. The outcome predictors for poor renal survival were the presence of oliguria (HR-5.11, P=0.035), severe hypertension (HR-11.51, P=0.019), estimated glomerular filtration rate <15 mL/min/1.73 m2 at presentation (HR-5.05, P=0.007), percentage of crescents (HR-10.66, P=0.001), presence of fibrous crescents (HR-6.34, P=0.001), and interstitial fibrosis and tubular atrophy (HR-8.88, P=0.0046). The overall outcome of the study revealed complete recovery (n=12), partial recovery (n=6), chronic kidney disease (n=3), and end-stage renal disease (n=13). The renal survival in patients with ≥50% crescents was poor (P=0.037) as compared to subjects with <50% crescents. Conclusion: Renal survival can be predicted by the severity of presenting features and histopathological markers. Two-thirds of patients had type II CGN with renal survival outcomes similar to type III CGN. The percentage of crescents is the most important predictor of renal survival. [ABSTRACT FROM AUTHOR]

Objective: Continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) are main modalities for end stage renal disease (ESRD) patients, and those have been covered by National Health Insurance (NHI) scheme since 2014 in Indonesia. This study aims to update the cost-effectiveness model of CAPD versus HD in Indonesia setting. Results: Compared to HD, CAPD provides good value for money among ESRD patients in Indonesia. Using societal perspective, the total costs were IDR 1,348,612,118 (USD 95,504) and IDR 1,368,447,750 (USD 96,908), for CAPD and HD, respectively. The QALY was slightly different between two modalities, 4.79 for CAPD versus 4.22 for HD. The incremental cost-effectiveness ratio (ICER) yields savings of IDR 34,723,527/QALY (USD 2460).

To investigate the prevalence of depression and anxiety in patients undergoing maintenance hemodialysis (MHD) in Hohhot, a large city on the northern border of China, and to identify independent risk factors for depression and anxiety in these patients. Patients receiving MHD for >3 months were enrolled in the four largest hemodialysis centers between September 2020 and December 2020. Depression and anxiety were assessed using the Zung self-rated depression scale (SDS) and Zung self-rated anxiety scale (SAS), respectively, with demographic and other data collected for logistic regression analyses. Among 305 MHD patients included in this study, the prevalence of depression was 55.1%, including 27.5%, 21.0%, and 6.6% with mild, moderate and severe cases, respectively. The prevalence of anxiety was 25.9%, with 20.0%, 4.6%, and 1.3% having mild, moderate, and severe cases, respectively. An independent protective factor for depression was family income of ≥1415 US dollars/month relative to <157 US dollars/month (odds ratio [OR] 0.209, 95% confidence interval [CI] 0.065–0.673), and predictors of depression included ≥3 comorbidities (OR 18.527, 95% CI 1.674–205.028) and severe pruritus (OR 15.971, 95% CI 5.173–49.315). Independent predictors of anxiety included infrequent exercise (OR 3.289, 95% CI 1.411–7.664) and severe pruritus (OR 5.912, 95% CI 1.733–20.168). The correlation between depression and anxiety in these patients was significant (rs = 0.775, p < 0.001). MHD patients in Northern China had high prevalence rates of depression (55.1%) and anxiety (25.9%). Lower family income, more comorbidities, and a higher degree of pruritus were predictors of depression, while infrequent exercise and severe pruritus were predictors of anxiety. Depression correlated significantly with anxiety. Attention should be given to family income, comorbidity, exercise, and pruritus severity for improved management of depression and anxiety among MHD patients. [ABSTRACT FROM AUTHOR]

Background: Clonidine is a frequently prescribed long-term antihypertensive medication in hemodialysis (HD) patients in the USA, but its safety and efficacy has not been clearly established in the HD population. Objective: To evaluate, we conducted a systematic review and meta-analysis on the safety and efficacy of clonidine in HD patients. Methods: Keyword search of "clonidine" and "dialysis" was conducted through April 2021 in PubMed, Cochrane Library, Web of Science, Scopus, and ClinicalTrials.gov databases. Inclusion criteria were as follows – study design: randomized controlled trials, cohort studies, prospective studies, retrospective studies, or case series; subjects: adult HD patients; main outcome: blood pressure (BP) and safety; language: English; and article type: peer-reviewed publications. Studies that examined the effects of clonidine in populations other than adult HD patients were excluded. Meta-analysis was performed on BP reduction outcomes. Results: Eight studies met the inclusion criteria for the systematic review, including prospective pre-post studies (2), double-blind controlled trial (1), single-blinded placebo-controlled trial (1), crossover open-label clinical trial (1), retrospective analysis (1), and case report series (2). Three studies included in the meta-analysis ranged from 2 to 12 weeks duration, with a collective sample size of 24 (ages 12–77 years). Risk of bias, assessed using the ROBINS-1 tool, was high for all included studies. Significant adverse effects reported included hypotension, light-headedness, drowsiness, dry mouth, rebound hypertension, and contact dermatitis from patch application. Short-term clonidine use was associated with significant improvement in systolic BP (pooled effect: −12.985 mm Hg, 95% CI [−7.878, −18.092], p < 0.001), while changes in diastolic BP were not statistically significant (−11.119 mm Hg, 95% CI [−22.725, 0.487], p = 0.060). No data currently support the long-term efficacy of clonidine in HD patients. This study was unfunded and was developed using PRISMA guidelines and registered on PROSPERO (CRD42018112042). Conclusions: There is no evidence supporting the long-term use of clonidine in the HD population and a significant side-effect profile. There is low-quality evidence demonstrating the efficacy of clonidine in lowering BP in HD patients in short-term use, but significant safety concerns remain. Fluid removal strategies and other antihypertensives should be used over clonidine for long-term BP control in the HD population. [ABSTRACT FROM AUTHOR]

Background: Right ventricular dysfunction is a major cause of heart failure and mortality in end‐stage renal disease patients. Scarce data is available regarding the comparison of echocardiographic right ventricular function in end‐stage renal disease patients on hemodialysis (HD) and peritoneal dialysis (PD). The aim of the study was to evaluate the long‐term impacts of different dialysis modalities on right ventricular function assessed by conventional echocardiography, in end‐stage renal disease patients with preserved left ventricular function. Methods: The study included 120 patients grouped as follows: PD (n = 40), HD with arterio‐venous fistula (n = 40), and healthy control subjects (n = 40). Conventional echocardiography was performed on all patients. A classification of right ventricular function was defined in HD patients by using tricuspid annular plane systolic excursion (TAPSE), right ventricular myocardial performance index (RV‐MPI), fractional area change (FAC), and tricuspid lateral annulus systolic velocity (Sa) values. Correlation analysis was performed by using the right ventricular dysfunction score, clinical, and echocardiographic parameters. Results: The mean age of the study population was 51.9 ± 13.1 years and 47.5% were females. TAPSE and Sa velocity were found to be significantly lower and RV‐MPI was significantly higher in patients undergoing HD, compared with control and PD patients. Logistic regression analysis showed that HD treatment was an independent risk factor for developing right ventricular dysfunction. Conclusion: RV function was impaired in patients undergoing HD compared with patients on PD. [ABSTRACT FROM AUTHOR]

Adverse cardiovascular events are a significant cause of mortality in end-stage renal disease (ESRD) patients. High-risk plaque anatomy may be a significant contributor. However, their atherosclerotic phenotypes have not been described. We sought to define atherosclerotic plaque characteristics (APC) in dialysis patients using artificial-intelligence augmented CCTA. We retrospectively analyzed ESRD patients referred for CCTA using an FDA approved artificial-intelligence augmented-CCTA program (Cleerly). Coronary lesions were evaluated for APCs by CCTA. APCs included percent atheroma volume(PAV), low-density non-calcified-plaque (LD-NCP), non-calcified-plaque (NCP), calcified-plaque (CP), length, and high-risk-plaque (HRP), defined by LD-NCP and positive arterial remodeling >1.10 (PR). 79 ESRD patients were enrolled, mean age 65.3 years, 32.9% female. Disease distribution was non-obstructive (65.8%), 1-vessel disease (21.5%), 2-vessel disease (7.6%), and 3-vessel disease (5.1%). Mean total plaque volume (TPV) was 810.0 mm3, LD-NCP 16.8 mm3, NCP 403.1 mm3, and CP 390.1 mm3. HRP was present in 81.0% patients. Patients with at least one >50% stenosis, or obstructive lesions, had significantly higher TPV, LD-NCP, NCP, and CP. Patients >65 years had more CP and higher PAV. Our study provides novel insight into ESRD plaque phenotypes and demonstrates that artificial-intelligence augmented CCTA analysis is feasible for CAD characterization despite severe calcification. We demonstrate elevated plaque burden and stenosis caused by predominantly non-calcified-plaque. Furthermore, the quantity of calcified-plaques increased with age, with men exhibiting increased number of 2-feature plaques and higher plaque volumes. Artificial-intelligence augmented CCTA analysis of APCs may be a promising metric for cardiac risk stratification and warrants further prospective investigation. • Artificial intelligence augmented CCTA can accurately provide plaque analysis in ESRD patients, even with severe CAD. • ESRD patients have high plaque burden, frequent stenoses, and increasing calcified plaques with age. • Atherosclerotic plaque characteristics using artificial intelligence augmented CCTA may provide clinical risk prognostication.

Background: RDW is critical to the clinical diagnosis and progression of ESRD. There is currently little data on the relationship between RDW and ESRD in sub-Saharan Africa. Because of this, the present study evaluates RDW in patients with ESRD and associated factors in Addis Ababa, Ethiopia. Methods: The hospital-based cross-sectional study design was conducted on a total of 83 patients. RDW, MCV, SCR, BUN, GFR, FBS and serum albumin were determined. Blood pressure (mmHg), weight (kg), height (m), MUAC (cm) and BMI (kg/m2) were also measured. Data entry was via Epi-data version 3.4 and analyzed with SPSS version 26.0. A multivariate logistic regression analysis with a p-value < 0.05 at a 95% confidence interval was used to identify the associated factors of RDW. Results: A total of 83 ESRD patients participated, with a response rate of 95.4%. RDW ranged from 15.5% to 23.6% with a mean of 17.40% + 1.46%. Anisocytosis was present in 98.8% of patients. Of 83 patients, 66.3% were hypertensive, 20.5% had diabetes, and the remaining 13.3% had other conditions (glomerulonephritis and peripheral vascular disease). The mean GFR value was 5.20 mL/min/1.73 + 1.58. RDW showed a significant association with GFR (AOR: 4.6, 95% CI [1.27, 20.74], P = 0.047), alcohol consumption (AOR: 13.4, P = 0.012, 95% CI [1.97, 22.62]), recurrent kidney disease (AOR=25.6, P=0.016, 95% CI [1.85, 53.71]) and use of medication (AOR=00.2, P=0.044), 95% CI [0.03, 0.95]). Conclusion: RDW showed a significant association with GFR, recurrent kidney disease, alcohol consumption, and medication use in hemodialysis-dependent ESRD patients. The mechanisms of RDW disruption in ESRD patients need further investigation. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to assess the presence of elbow pain and its relationship with vascular access site for hemodialysis in end-stage renal disease patients. Methods: One-hundred and nine chronic end-stage renal disease patients over 18 years of age undergoing hemodialysis treatment were enrolled in the study. Patients who had undergone surgery of the upper extremity in the last three months and patients with cancer, chronic hearing loss, or neurologic diseases were excluded. Sociodemographic features were evaluated. The Beck Depression Inventory, the Nottingham Health Profile, the Disabilities of the Arm, Shoulder and Hand Score, and the Visual Analogue Scale were administered to all patients. Results: One-hundred and nine patients (38 women, 71 men) participated in the study. The mean age of the patients was 62.22 ± 11.64. The patients were grouped based on the presence of elbow pain into Group 1 (elbow pain positive, n=30) and Group 2 (elbow pain negative, n=79). There was a statistically significant difference between the groups in terms of vascular access site and elbow pain site (p=0.002). In addition, the patients with elbow pain were mostly women, and this result was statistically significant (p<0.05). Conclusions: According to the results of this study, there may be a relationship between elbow pain and hemodialysis vascular site. [ABSTRACT FROM AUTHOR]

Albumin (HSA) is a multifunctional protein and due to its free Cys34 thiol group, represents a main source of free thiols in the circulation. This property of HSA, combined with its ability to sequester redox active Cu(II) ions, makes HSA a dominant circulatory antioxidant. End stage kidney disease (ESRD) is a condition accompanied by elevated oxidative stress. The aim of the present study was to examine changes in the antioxidative capacity of HSA and Cu(II) binding affinity in patients on peritoneal dialysis (PD), and relate it to the Cys34 thiol group content and other structural changes of this molecule. HSA molecules are modified in ESRD patients subjected to PD, having significantly lower thiol group and bound Cu(II) content, reduced antioxidant capacity, an increased content of advanced glycation end-products and altered conformation. Also, Cu(II) binding capacity of HSA in these patients is impaired, since a significant portion of the high-affinity metal-binding site is unable to interact with Cu(II). Taking into account that the concentration of Cu(II) in the circulation of ESRD patients is much higher than in healthy persons and that Cu(II) binding capacity of HSA in these patients is significantly impaired, HSA may be considered as a novel circulatory pro-oxidant, thus exacerbating oxidative stress. [Display omitted] • Albumin molecules are modified in PD patients. • Albumin has impaired antioxidant properties and increased content of AGEs. • Cu(II) binding capacity of albumin in PD patients is impaired. • Albumin may be considered as a novel pro-oxidant in PD.

Background and Objective: Hemodialysis is an important replacement therapy for 70-90% of patients with end-stage renal disease (ESRD). Arteriovenous fistula (AVF) is the vascular access of choice in these patients due to its higher efficiency and lower risk of mortality compared to arteriovenous grafts. This study was conducted to determine the frequency of vascular access types used in hemodialysis centers of Gorgan, Iran. Methods: This descriptive-analytical study was done on 200 hemodialysis patients (101 men and 99 women) at 5 Azar and Sayyad Shirazi hospitals in Gorgan, north of Iran, during April 2020 to July 2021. The subjects were selected by the census method. Information including age, sex, education level, duration of dialysis, the initial and current types of vascular access, site of vascular access, history of diabetes or hypertension, race, and history of smoking were recorded in a checklist. Results: The mean age of women and men was 58.34±4.71 and 57.95±13.76 years, respectively. In addition, 61.5% of the patients were under 3 years old. The most commonly used vascular access to initiate dialysis was non-cuffed temporary catheters (69%) and AVF (24%). Smoking, ethnicity, diabetes, hypertension, and gender had no significant association with the type of vascular access used. In addition, there was no significant relationship between the duration of dialysis and the type of vascular access. Conclusion: Considering the diversity of catheters and fistulas, it is necessary to emphasize that the use of AVF in patients undergoing dialysis for the first time and the timely placement of AVF in ESRD patients can improve the quality of life of the patients. It is also recommended to use jugular catheters instead of subclavian catheters when required. [ABSTRACT FROM AUTHOR]

Background: Worldwide, data are conflicting on the prevalence of Helicobacter pylori (Hp) infection in Hemodialysis (HD) population. In Egypt, the data on this population are rather limited. Objectives: The aim of this cross-sectional study was to screen HD patients with Gastrointestinal (GI) symptoms for the prevalence of Hp infection using non-invasive serological testing for Immunoglobulin G (IgG) antibody and then to compare the screening data with the confirmatory esophagogastroduodenoscopy (EGD) findings. Patients and Methods: From January 2020 to June 2021, the sera of one hundred patients with GI complaints were screened for IgG antibody against Hp, among them fifty patients underwent EGD as per indication. Univariate and multivariate analysis were performed to compare serological versus invasive testing performance for Hp infection. Results: In the present study, (60%) of the screened study population demonstrated a positive IgG against Hp, whereas the EGD findings confirmed Hp infection in (50%) of the fifty patients who underwent a confirmatory EGD. In comparison to EDG findings, IgG Antibody sensitivity and specificity for diagnosis of Hp infection was 65.5 % and 52.4 % respectively. Conclusion: Among the one hundred HD patients screened for IgG against Hp, we found a seroprevalence of 60%; however, the performance characteristics of IgG antibody were limited. Further studies are warranted to explore these findings. [ABSTRACT FROM AUTHOR]

Introduction: Parathormone (PTH) and phosphorus, which are considered as uremic toxins, are associated with reduced red cell survival, yet with unproven mechanism. We aimed to assess the relation between PTH and phosphorus levels and eryptosis in patients with CKD5d treated by hemodialysis. Methods: In a cohort of 85 patients with CKD5d treated by conventional hemodialysis, the percent of annexin V‐binding RBCs was assessed by flow cytometry to indicate the percent of eryptotic RBCs. Findings The median percent of annexin V‐binding RBCs was 2.3 (1.4–4.7)%. On linear regression analysis, PTH was independently associated with the percent of annexin V‐binding RBCs (β = 0.003; 95% CI: 0.002–0.004; p < 0.001). The percent of annexin V‐binding RBCs differed significantly in patients with low PTH (<150 pg/mL; 27/85, 31.8%), target PTH (150–600 pg/mL; 32/85, 37.6%), and high PTH (>600 pg/mL; 26/85, 30.6%) groups (1.24 [0.65–1.85]; 2.46 [1.73–4.05]; and 4.82 [3.45–5.61]%, respectively; p < 0.001). Considering the tertiles of the percent of annexin V binding RBCs, PTH increased significantly from 85 (50.6–273) in the 1st to 298.3 (172.8–606.8) in the 2nd and 827.6 (357.4–1171.3) pg/mL in the 3rd tertiles (p < 0.001). Phosphorus and calcium levels as well as the CaxPh product were similar among the three tertiles (p > 0.05). Discussion: Patients with CKD5d express high rates of eryptosis. PTH excess in those patients may result in further eryptosis enhancement, and this represents a potential pathogenic mechanism linking hyperparathyroidism with the anemia of CKD.

Background / Aim: Nephrotic syndrome (NS) is a clinical syndrome characterised by massive proteinuria > 3.5 g in 24 h urine, hypoalbuminaemia, hyperlipidaemia and oedema. Aim of this study was to determine the aetiology and frequency of kidney diseases that occur as the cause of NS in adults in the Republic of Srpska and the progression of renal insufficiency, disease outcomes and efficacy of applied therapy. Methods: The retrospective study included patients aged 18 to 80 hospitalised between 2014 and 2018 due to clinically and laboratory-manifested NS. In patients with suspected primary glomerular disease, a kidney biopsy with immunofluorescent dyeing was performed. The first examination involved hospital admission and the next check-up six months after the first hospitalisation. Basic clinical parameters were followed: creatinine, clearance creatinine, albumin, total protein, cholesterol, total protein in 24 h urine and microscopy of urine during the first hospitalisation and repeated same laboratory findings on control. The progression of kidney failure during this period was assessed, as well as the efficacy of immunosuppressive therapy. Results: In primary NS category membranous glomerulonephritis (MGN) was present at 40.7 % of patients, followed by focal segmental glomerulosclerosis (FSGS) 21.7 %, membranoproliferative glomerulonephritis (MPGN) 11.9 % and IgA glomerulonephritis (IgAN) 11.9 %. Nephroangiosclerosis was verified as the most common cause of secondary NS with 28.8 % and lupus nephritis 21.2 %, followed by ANCA-associated GN (11.5 %) and diabetic nephropathy (11.5 %). Thirty-four patients (21 %) died during the follow-up. Thirty-four patients (18.6 %) progressed to end stage renal disease during the five-year follow-up. Conclusion: The pathology of kidney disease in older patients is often very complex; therefore, a kidney biopsy should be conducted at an early stage of kidney disease for the purpose of obtaining an accurate diagnosis, determining appropriate treatment and thus improving the prognosis of the patient.

Sexual dysfunction (SD) is common in end stage renal disease (ESRD) patients, affecting their quality of life. Sexuality is not a subject that patient's, particularly Muslim women, discuss when they require assistance. They need to develop strategies to cope with SD. The qualitative study explored how Muslim women with ESRD cope with SD. A phenomenological approach was adopted and data were collected using semistructured individual interviews. Purposive sampling was used to recruit 20 participants from two southern regional hospitals in Thailand between September and December, 2018. Recruitment continued until data saturation was reached. Data were analysed using Colaizzi's phenomenological approach. Participants were aged between 30 and 63 years (mean = 45.25, SD = 8.50). Ten were receiving haemodialysis (HD) and 10 were receiving continuous ambulatory peritoneal dialysis (CAPD). Five themes were identified: (1) receiving compassion and understanding from their partner, (2) being afraid of sin if not taking responsibility as a wife's role, (3) denying and ignoring sexuality, (4) being patient to keep their family together and (5) accepting SD associated with God's will. The findings suggest that understanding Islamic views on SD and how the religion's beliefs and practices influence SD and the way Muslim women cope with it. Hence, it is critical in opening lines of communication with patients and their partners to help them cope with SD. [ABSTRACT FROM AUTHOR]

Background: Health-related quality of life (HRQOL) has a direct association with increased morbidity and mortality among end stage renal disease patients. Valid and reliable instruments to measure the HRQOL of patients with end stage renal disease are therefore required. This study aimed to translate, culturally adapt and evaluate the psychometric properties of the Amharic version of the Kidney Disease Quality of Life-36 (KDQOL-36) instrument in Ethiopian patients with end stage renal disease undergoing hemodialysis.Methods: The KDQOL-36 instrument was developed for individuals with kidney disease who are being treated with dialysis and includes both generic and disease-specific components. The KDQOL-36 was translated to Amharic language and distributed to a cross-sectional sample of 292 hemodialysis patients. The psychometric evaluation included construct validity through corrected item-total correlation, confirmatory factor analysis and known group analysis. Convergent validity was evaluated by correlations between each of the three kidney disease targeted scales (symptoms/problems list, burden of kidney disease and effects of kidney diseases) and the European Quality of Life 5D-5L and Visual Analog Scales. Regarding reliability, internal consistency and test-retest reliability were assessed.Results: Two hundred ninety-two patients with a mean age of 48 (SD ± 14.7) completed the questionnaire. Corrected item- total correlation scores were > 0.4 for all items. Confirmatory factor analysis revealed a two χ2 /df was 4.4, Root Mean Square Error of Approximation (RMSEA) = 0.108 (90% CI 0.064-0.095), Comparative Fit Index (CFI) = 0.922, Tucker Lewis Index (TLI) = 0.948 and Standardized Root mean-squared residual (SRMR) = 0.058) and three χ2 /df = 3.1, RMSEA = 0.085 (90% CI 0.064-0.095), CFI = 0.854, TLI = 0.838 and SRMR = 0.067) factor models for the generic and disease specific components respectively. The mean scores of the three kidney disease targeted domains were correlated to the EQ-5D-5L & VAS with correlation coefficients of large magnitude (0.55-0.81). The reliability of the instrument was satisfactory (Cronbach's alpha = 0.81-0.91) and Intra-class correlation (ICC) = 0.90-0.96).Conclusion: The Amharic version of the KDQOL-36 is a reliable and valid instrument recommended for assessment of HRQOL of Ethiopian patients on hemodialysis.

Introduction: The effect of age on health outcomes in kidney transplantation remains inconclusive. This study aimed to analyze the relationship between age at time of kidney transplantation with mortality, graft loss and self-rated health status in adult kidney transplant recipients. Methods: This study used data from the Swiss Transplant Cohort Study and included prospective data of kidney transplant recipients between 2008 and 2017. Time-to-event analysis was performed using Cox’ regression analysis, and -in the case of graft loss- competing risk analysis. A random-intercept regression model was applied to analyse self-rated health status. Results: We included 2,366 kidney transplant recipients. Age at transplantation linearly predicted mortality. It was also predictive for graft loss, though nonlinearly, showing that recipients aged between 35 and 55 years presented with the lowest risk of experiencing graft loss. No relationship of age with self-rated health status was detected. Conclusion: Higher mortality in older recipients complies with data from the general population. The non-linear relationship between age and graft loss and the higher scored self-rated health status at all follow-up time-points compared to the pre-transplant status -regardless of age- highlight that age alone might not be an accurate measure for risk prediction and clinical decision making in kidney transplantation.

Background: Hemodialysis (HD) seems to be the most often used Renal Replacement Therapy (RRT) modality worldwide, and it is the primary modality in the majority of instances with extended RRT. The ability to provide our patients with high-quality HD treatment while also increasing their chances of survival is heavily reliant on the functionality of the vascular access (VA). Despite the fact that it is a very necessary component of all clinical practise standards, it is the most expensive individual component of RRT. Objectives: This study was aimed at comparing between the group with Angio access failure and group without Angio access failure and predicting Angio access failure among end stage renal failure patients in Southern Egypt. Subjects and Methods: a prospective cohort study among 125 patients with end stage renal failure at Aswan University. The research comprised patients who had NCVA placement [intra-atrial catheter (IAC) and trans-lumbar catheter (TLC)] between January 1, 2020, and December 31, 2020. Results: The duration of previous RRT was significantly higher among the Angio access failure than the group without Angio access failure. In multivariate analysis using logistic regression, the age, duration of previous RRT, diabetes, IHD (ischemic heart disease), PVD (peripheral vascular disease) and CVD (cardiac vascular disease) were significantly direct predictors of the Angio access failure in the first one year. Conclusion: In conclusion the failure of Angio access was positively associated with age, previous RRT and other comorbidities. [ABSTRACT FROM AUTHOR]

The adherence to the hemodialysis program of patients with end-stage renal disease is a serious problem. Inclusion in a dialysis program presupposes varying degrees of restrictions with which the patient must comply in order to ensure optimal health and quality of life. This is a review of the factors that affect the adherence of patients to hemodialysis requirements. Regular hemodialysis requires the patient to make adjustments at the emotional and cognitive level, and to adopt appropriate behavior. Factors that are commonly reported to play a role in compliance include marital and occupational status, the new lifestyle, perceptions of the disease, awareness of the consequences of the disease, the duration of hemodialysis, limitations of treatment, effective communication, self-management of the disease and social support. The role of age, gender and educational level has not been clarified, as in most studies they were not associated with adherence, but in others an effect was detected. The contribution of the medicalnursing team, and especially the nurses, is documented to be of significance in achieving the adherence of patients undergoing hemodialysis to the regimen, due to the relationship of trust that develops over the duration of the dialysis program. In conclusion, in order to meet the requirements of the dialysis program, patients undergoing dialysis need to develop specific skills and self-care skills. They need support from the family and social environment, and their socio-economic situation should be such that it is not difficult for them to follow the required diet and medica tion regimen. The profile of the adherent patient is created by the interaction of personal and sociocultural factors that promote or hinder therapeutic adherence. [ABSTRACT FROM AUTHOR]

Background: When compared to patients with normal renal function, patients with chronic kidney disease develop higher in‐hospital complications post implantable cardioverter‐defibrillator (ICD) therapy. However, real world data on in‐hospital complications post ICD therapy in patients with end stage renal disease (ESRD) is limited. In this study, we aim to explore the procedure‐related complications of ICD therapy in patients with ESRD. Methods: Using the nationwide inpatient sample (NIS) database, we conducted a retrospective analysis on ESRD patients who underwent inpatient ICD placement from 2010 to 2016. Using 1:2 propensity score matching, we compared ESRD patients to those with normal renal function. Outcomes of interest were postoperative hemorrhage and hematoma formation, blood transfusion, pericardial complications, mechanical complications requiring lead revision, vascular injury, in‐hospital mortality, and length of stay. Results: Our sample included 40,075 cases with subsequent propensity score matching between ESRD and normal renal function. Comparatively, patients with ESRD had higher odds of postoperative hemorrhage (Odds ratio [OR] = 1.67, 95% confidence interval [CI] 1.4–1.99, p = <.0001), blood transfusion (OR, 3.88; CI 3.29–4.56; p = <.0001), mechanical complications requiring lead revision (OR, 1.24; CI 1.01–1.51; p =.035), vascular injury (OR, 2.02; CI 1.27–3.24; p =.0027), in‐hospital mortality (OR, 4.56; CI 3.08–6.76; p = <.0001), and longer hospitalization (11 vs. 7 days, p = <.0001), but without significant difference in pericardial complications (OR, 1.9; CI 0.92–1.54; p = <.18). Conclusion: In this large contemporary cohort, patients with ESRD undergoing inpatient ICD therapy are at higher risk of developing postprocedural complications including hemorrhage and hematoma, blood transfusion, mechanical complications requiring lead revision, and in hospital mortality, without increased risk of pericardial complications.

Background: All patients with chronic renal failure need vascular access for hemodialysis that is possible with CVP line but it shorter life. The most suitable and effective vascular access on long term basis is the creation of arteriovenous fistula (AVF). The objective of this study was to compare the patency rate of Radiocephalic vs. Brachiocephalic AVFs in population of D.I.Khan division, Pakistan. Materials & Methods: This randomized control trail was conducted in Department of Surgery Gomal Medical College, D.I.Khan, Pakistan from January 2017 to December 2019. 266 patients were equally randomly allocated into Brachiocephalic AVF (BCAVF) and Radiocephalic AVF (RCAVF). Sex, age groups and patency of AVT were nominal variables. Data for sample was described by count & percentages and for population as confidence interval at 80% confidence level. McNemar chi-square test was used to test hypothesis to compare patency rate of Brachiocephalic AVF vs. Radiocephalic AVF. Results: Patency was present in 129 (97%, 80% CI 94.45-98.39%) and absent in four (3%, 80% CI 1.61-5.55%) cases in Brachiocephalic, while it was present in 107 (80.5%, 80% CI 76.04-84.86%) cases and absent in 26 (19.5%, 80% CI 15.52-24.32%) cases in Radiocephalic AVF group. McNemar chi-square test showed p <.0001, so the null hypothesis was rejected, showing higher patency rate in BCAVF. Conclusion: Brachiocephalic AVF creation is more ideal in terms of patency and maturation as compare to Radiocephalic AVF because of increased vessel diameter and increased arterial pressure at proximal site below elbow joint.

Objectives: Assessment of health related quality of life (HRQOL) is an essential part of evaluation of end stage renal disease (ESRD) as we have conducted this study on haemodialysis patients to see the HRQOL and to asses and compare the parameters which influence physical and mental health. Materials and Methods: This was a single centre study on haemodialysis patients using Short Form 36 (SF-36) of Kidney Disease Quality of Life (KDQOL). All the eight domains of HRQOL were assessed individually as well as summary scores for mental health (MCS Mental composite summary) and physical health (PCS Physical composite summary) were also evaluated. The questionnaire was completed by patient themselves and the clinical data was extracted from the medical records with prior consent from the patient. Results and discussion: The study participants showed a female predominance of 66% with a lower PCS and MCS scores among female participants in comparison to their male counterparts. Overall summary scores showed a lower PCS (38.71±8.15) than MCS (42.79±11.6) which reflects better mental health than physical health in the study population. A multiple regression analysis showed, the presence of residual renal function (ß= -0.421, p= 0.02), duration of dialysis (ß= 0.405, p= 0.03) and haemoglobin less than 12g/dL (ß= 0.379, p= 0.02) were significant predictors of MCS. Conclusion: HRQOL in haemodialysis patients are influenced by socio-demographic as well as clinical parameters. In our population, kidney disease affects physical health more than mental health and the reasons are multifactorial. [ABSTRACT FROM AUTHOR]

Hemodialysis affects the socio-economic status of patients with end stage renal disease (ESRD) resulting in a large number of psychological disorders for both the patients and their families. The purpose of this study is to explore the experiences of patients undergoing dialysis at Greater Regional Hospital in Ghana. The researchers employed a qualitative phenomenological research design using and analyzed using Interpretive Phenomenological Analysis. A purposive sampling technique was employed by the researchers to select 16 participants who were engaged in face-to-face in-depth interviews conducted. The socio-demographic characteristics revealed that majority were males (n = 11; 69%)and more than half of the participants (n = 14; 87.5%), were over 40 years. Again, most of the participants indicated spending between 150USD to 180USD weekly on dialysis treatment alone. The study revealed 3 themes and 13 subthemes emerged from the analysis of this data. The main themes were the Physical experiences of patients prior to starting dialysis, personal experiences during dialysis and socioeconomic burden on the participants. Participants faced challenges prior to and whilst on dialysis however the symptoms were better whilst on dialysis. It is therefore recommended that participants with ESRD are supported to go through dialysis treatment to enhance their quality of life. [ABSTRACT FROM AUTHOR]
