Introduction: Due to treatment of end‐stage‐renal‐disease (ESRD), continuous peritoneal dialysis (CAPD) is used in 11% of cases and is associated with several PD‐associated infections. Methods: Clinical data on 71 patients with CAPD were evaluated in addition to exit site infections and episodes of acute peritonitis (AP). Results: There were 39 men and 32 women. Average age was 61 years when we began CAPD and average time spent on CAPD program was 3.35 years. Illness that dominantly caused ESRD was diabetes (23 patients). Exit site infection was mostly caused by S epidermidis‐MRSE and AP was most commonly caused by Staphylococcus sp. group. Most common cause of death was cardiovascular disease. At the end of this study, 9 patients were alive and still on CAPD, 10 were transplanted, 15 switched to HD and 36 died. Conclusion: Optimal prevention measures and treatment of infectious complications in CAPD is necessary for better treatment possibilities. [ABSTRACT FROM AUTHOR]

Introduction: COVID-19, caused by SARS-CoV-2, has resulted in significant mortality and morbidity worldwide. Patients of chronic kidney disease who are on maintenance hemodialysis represent a vulnerable population cohort that is susceptible to severe disease. Hence, it is of utmost importance to prioritize vaccination in this population and to assess their response to said vaccination. Methods: This prospective analytical study was conducted at the Institute of Nephrology, Madras Medical College, between August 2021 and February 2022. Patients of chronic kidney disease stage 5 dialysis (CKD5D) who were on maintenance hemodialysis and who consented to receive COVID-19 vaccine were studied. Serum samples were obtained before vaccination, ≥28 days after receiving the first dose of the vaccine, and ≥28 days after receiving the second dose. Antibody titers against the spike protein were estimated using the Roche chemiluminescent immunosorbent assay. Patients were grouped into non-responders/seronegative (<0.8 U/ml) and responders/seropositive (≥0.8 U/ml), with a value ≥250 U/ml considered as robust response. Results: A total of 96 patients were included. The mean age was 36.70 (±11.53) years and 77.1% of them were male. The median dialysis vintage was 2 (IQR: 0.95-5) years. Twelve patients (9.9%) had a prior COVID-19 infection. Sixty-seven (69.8%) patients had received Covaxin and 29 (30.2%) had received Covishield vaccines. Among the 17 patients who were seronegative at baseline, 4 (23.52%) became seropositive after the first dose of the vaccine, and 11 (64.7%) were seropositive after the second dose, with high titers ("robust response") achieved in two patients (11.76%). No antibody response, despite two doses of the vaccine, was noted in six patients (35.29%). Conclusion: Our study showed a high baseline seropositivity rate, even prior to vaccination, which indicated a high rate of subclinical COVID infection. Among those who were seronegative at baseline, the seroconversion rate after two doses of Covaxin or Covishield was 64.70%. [ABSTRACT FROM AUTHOR]

Background: Epidemiologic studies on the effects of long-term exposure to ozone (O3) have shown inconclusive results. It is unclear whether to O3 has an effect on chronic kidney disease (CKD). We investigated the effects of O3 on mortality and renal outcome in CKD. Methods: We included 61,073 participants and applied Cox proportional hazards models to examine the effects of ozone on the risk of end-stage renal disease (ESRD) and mortality in a two-pollutants model adjusted for socioeconomic status. We calculated the concentration of ozone exposure one year before enrollment and used inverse distance weighting (IDW) for interpolation, where the exposure was evenly distributed. Results: In the single pollutant model, O3 was significantly associated with an increased risk of ESRD and all-cause mortality. Based on the O3 concentration from IDW interpolation, this moving O3 average was significantly associated with an increased risk of ESRD and all-cause mortality. In a two-pollutants model, even after we adjusted for other measured pollutants, nitrogen dioxide did not attenuate the result for O3. The hazard ratio (HR) value for the district-level assessment is 1.025 with a 95% confidence interval (CI) of 1.014–1.035, while for the point-level assessment, the HR value is 1.04 with a 95% CI of 1.035–1.045. The impact of ozone on ESRD, hazard ratio (HR) values are, 1.049(95%CI: 1.044–1.054) at the district unit and 1.04 (95%CI: 1.031–1.05) at the individual address of the exposure assessment. The ozone hazard ratio for all-cause mortality was 1.012 (95% confidence interval: 1.008–1.017) for administrative districts and 1.04 (95% confidence interval: 1.031–1.05) for individual addresses. Conclusions: This study suggests that long-term ambient O3 increases the risk of ESRD and mortality in CKD. The strategy to decrease O3 emissions will substantially benefit health and the environment. [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.

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]

Background: Patients with end stage renal disease (ESRD) are at a higher risk of developing tuberculosis (TB) due to the immunosuppressed state along with concomitant comorbidities and socioeconomic and demographic factors. Data on the prevalence of tuberculosis in ESRD are scarce despite the high burden of the disease in developing nations. Methods: A multicenter, cross-sectional study was conducted at eight dialysis centers in Addis Ababa on the prevalence of TB among CKD patients on maintenance hemodialysis from August 2022 to October 2022 G.C. The study enrolled 263 participants selected by systematic random sampling. Data were collected by reviewing the patient's electronic medical records. The Collected data were analyzed using SPSS version 26.0. Results: Our study found a 27% prevalence of TB in patients with ESRD receiving maintenance hemodialysis (MHD). Pulmonary tuberculosis was the most prevalent form, and lymphadenitis was the most common extra-pulmonary tuberculosis (EPTB). Only 5.6% of the study participants had microbiologic evidence of TB. Chemistry and cytological studies from pleural fluid and imaging evidences were commonly used diagnostic modalities. The presence of HIV infection, longer duration of dialysis (> 1 year), and contact history with a known TB patient were all significantly associated with higher prevalence of TB among the study participants. Conclusion: Although there is a strong association between TB and CKD, there are no local data from Ethiopia. Our study identified a higher prevalence of TB among CKD patients on MHD. Thus, maintaining a high index of suspicion and early diagnosis and treatment of TB among ESRD patients on MHD and use of TB preventive therapy (TPT) is important in decreasing morbidity and mortality.

This article describes the care experience of a case of end stage renal disease in which the patient was unable to cope with the progression of the disease and caused spiritual distress. The nursing care period is from January 24 to February 23, 2021. Patient data was collected using physical, psychological, spiritual and social assessments, through direct care, medical records and interviews. The identified health issues were ineffective airway clearance, compromised skin integrity, and spiritual distress. Physiological problems were treated with nursing measures such as oral care, chest physiotherapy care, keeping the skin dry, and choosing an appropriate wound dressing method. The case effectively eliminated sputum, and there was no new sign of infection in the pressure injury wound. In terms of psychological problems, interprofessional collaborative practice provided psychological support and spiritual comfort, and guided the patient to participate in medical decisions and end-of-life discussions, conduct life reviews, build self-worth, and achieve the goal of spiritual wellness. Caregivers are encouraged to participate in courses on hospice care and advance care planning to enhance the sensitivity and communication skills of clinical care in this kind of case.

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.

Patients with chronic kidney disease (CKD) undergoing hemodialysis often experience significant itch secondary to their condition and a subsequent reduction in their overall quality of life. Current treatments are underwhelming, necessitating the search for new, effective therapeutic options to combat itch in this population. The purpose of this review is to explore the available data for the use of intravenous difelikefalin in patients with CKD undergoing hemodialysis. The pathophysiology of CKD-associated itch is multifactorial, with one proposed mechanism involving an imbalance in the endogenous opioid system, favoring upregulation of itch-activating μ-opioid receptors (MORs) and downregulation of itch-inhibiting κ-opioid receptors (KORs). Dysregulation of the immune system is also involved. Difelikefalin is a recent FDA approved treatment that functions as peripherally acting KOR agonist, targeting this imbalance in the endogenous opioid system seen in CKD patients with itch and having an anti-inflammatory effect on immune cells. Clinical data on intravenous difelikefalin is promising regarding its ability to reduce itch in CKD patients on hemodialysis and improve patient quality of life, with few, mild adverse side effects. As intravenous difelikefalin becomes more widely used in the clinical setting, further studies assessing long-term efficacy and safety will be needed. [ABSTRACT FROM AUTHOR]

Background: Osteoporosis (OS) and fractures are common in patients with end-stage renal disease (ESRD) and maintenance dialysis patients. However, diagnosing osteoporosis in this population is challenging. The aim of this research is to explore the common genetic profile and potential molecular mechanisms of ESRD and OS. Methods and results: Download microarray data for ESRD and OS from the Gene Expression Omnibus (GEO) database. Weighted correlation network analysis (WGCNA) was used to identify co-expression modules associated with ESRD and OS. Random Forest (RF) and Lasso Regression were performed to identify candidate genes, and consensus clustering for hierarchical analysis. In addition, miRNAs shared in ESRD and OS were identified by differential analysis and their target genes were predicted by Tragetscan. Finally, we constructed a common miRNAs-mRNAs network with candidate genes and shared miRNAs. By WGCNA, two important modules of ESRD and one important module of OS were identified, and the functions of three major clusters were identified, including ribosome, RAS pathway, and MAPK pathway. Eight gene signatures obtained by using RF and Lasso machine learning methods with area under curve (AUC) values greater than 0.7 in ESRD and in OS confirmed their diagnostic performance. Consensus clustering successfully stratified ESRD patients, and C1 patients with more severe ESRD phenotype and OS phenotype were defined as “OS-prone group”. Conclusion: Our work identifies biological processes and underlying mechanisms shared by ESRD and OS, and identifies new candidate genes that can be used as biomarkers or potential therapeutic targets, revealing molecular alterations in susceptibility to OS in ESRD patients.

Recent data, indicating that inflammatory bowel disease (IBD) may be a risk factor for future chronic kidney disease, highlight the need to study the safety and clinical effectiveness of advanced IBD therapies in patients with end stage renal disease (ESRD), defined as an eGFR <15 mL/min/1.73m2. Upadacitinib, a selective oral Janus kinase (JAK) 1 inhibitor, has demonstrated efficacy in the management of moderate to severe ulcerative colitis. There is also emerging data indicating that JAK inhibition may be clinically effective in the setting of steroid‐refractory acute severe ulcerative colitis (ASUC). There is, however, a lack of "real‐world" data documenting the use of JAK inhibitors in patients with ESRD. Here, we report the use of upadacitinib in a patient with ESRD for the management of steroid‐refractory ASUC, demonstrating, for the first time, the safe and clinically effective use of upadacitinib in this population.

Introduction: Chronic kidney disease is a widespread medical problem that leads to higher morbidity, mortality, and a decrease in the overall well-being of the general population. This is especially expressed in patients with end-stage renal disease (ESRD) undergoing maintenance haemodialysis. Several variables could be used to evaluate those patients' well-being and mortality risk. One of them is the presence of residual urine output.Materials and Methods: The study was conducted on 485 patients treated with maintenance haemodialysis. After enrollment in the study, which consisted of medical history, physical examination, hydration assessment, and blood sampling, each patient was followed up for 24 months. We used residual urine output (RUO) as a measure of residual renal function (RRF). The entire cohort was divided into 4 subgroups based on the daily urinary output (<=100mL per day, > 100mL to <=500mL, > 500mL to <=1000mL and > 1000mL).Results: The data show that the mortality rate was significantly higher in groups with lower RUO, which was caused mainly by cardiovascular events. Also, patients with higher RUO achieved better sodium, potassium, calcium, and phosphate balance. They were also less prone to overhydration and had a better nutritional status. Preserved RRF also had a positive impact on markers of cardiovascular damage, such as NT-proBNP as well as TnT.Conclusion: In conclusion, preserving residual urine output in ESRD patients undergoing maintenance haemodialysis is invaluable in reducing their morbidity and mortality rates and enhancing other favourable parameters of those patients.

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.

A novel simple optical sensor based on fast protein liquid chromatography was developed and tested for monitoring end stage renal disease (ESRD) patients treated with continuous ambulatory peritoneal dialysis (CAPD). The device provides direct determination of proteins and lower molecular weight metabolites in effluent peritoneal dialysate using ultraviolet (UV) photometric detection at the wavelengths 285 nm or 260 nm with deep ultraviolet light-emitting diodes. The sensor was calibrated with bovine serum albumin and nucleotides standard solutions. Chromatograms of peritoneal dialysate samples taken from a group of 28 ESRD patients were processed and approximated by a set of split-Gaussian functions. All chromatograms show three overlapping peaks: the first one represents proteins; the other two peaks probably correspond to mid- and low molecular weight metabolites. Strong correlation was reveled between the area of the first peak and total protein concentration determined by a standard biochemical assay, this makes possible estimation of peritoneal protein loss with a reasonable precision less than 15%. The area of the second peak correlated with dialysate optical density at a wavelength 355–365 nm, associated with the UV absorption of advanced glycation end (AGE) products. The third peak correlated with the optical density of the eluate at a wavelength 255–265 nm, associated with the UV absorption of purines and pyrimidines. Thus, we demonstrated the possibility of estimation of proteins and lower molecular weight metabolites in effluent peritoneal dialysate with the compact and affordable chromatographic optical sensor.

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]

Aims: Heart failure (HF) is one of the leading causes of cardiovascular morbidity and mortality. HF with preserved ejection fraction (HFpEF), or diastolic failure, accounts for half of all HF cases and differs from HF with reduced ejection fraction (HFrEF). Patients with HFpEF are typically older, female, and commonly seen with chronic kidney disease (CKD), one of the leading independent risk factors for mortality in these patients. Unfortunately, drugs that had shown significant improvements in mortality in HFrEF have not shown similar benefits in HFpEF. Recently, sodium glucose transporter 2 inhibitors (SGLT2i) have been shown to reduce cardiovascular morbidity and mortality in HFrEF patients and slow down CKD progression. This study aimed to elucidate the impact of this drug class on mortality and risk of end stage renal disease in patients with HFpEF, which is currently unclear. Methods and results: We retrospectively analysed the Research Data Warehouse containing electronic health records from de‐identified patients (n = 1 266 290) from the University of Mississippi Medical Center from 2013 to 2022. HFpEF patients had an average follow‐up of 4 ± 2 years. Factors associated with increased all‐cause mortality during HFpEF included age, male sex, and CKD. Interestingly, the only treatments associated with significant improvements in survival were angiotensin converting enzyme inhibitors/angiotensin receptor blockers and SGLT2i, regardless of CKD or diabetes status. Additionally, SGLT2i use was also associated with significant decrease in the risk of end stage renal disease. Conclusions: Our results support the use of SGLT2i in an HFpEF population with relatively high rates of hypertension, CKD, and black race and suggests that improvements in mortality may be through preserving kidney function.

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]

Background and aim: Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. We aimed to evaluate whether obesity is a risk factor for IgAN patients. Methods: A total of 1054 biopsy-proven IgAN patients were analyzed in this retrospective study. Patients were divided into four groups according to their body weight index (BMI) at the period of renal biopsy: underweight group (BMI< 18.5, N=75), normal weight group (18.5=BMI<24, N=587), overweight group (24=BMI<28, N=291) and obesity group (28=BMI, N=101). The endpoint of our study was end stage renal disease (ESRD: eGFR <15 mL/min/1.73 m2 or having renal replacement treatment). Kaplan-Meier analyses and Cox proportional hazard models were performed to evaluate renal survival. Propensity-score matching (PSM) was performed to get the matched cohort to evaluate the role of obesity in IgAN patients. Besides, the effect modification of obesity and hypertension in IgAN patients was clarified by the synergy index. Results: IgAN patients complicated with obesity had more severe renal dysfunction at the time of renal biopsy than those with optimal body weight. In addition, patients with obesity tended to have higher risk of metabolic disorders, such as hyperuricemia (64.4% vs 37%, p<0.001), hypertriglyceridemia (71.3% vs 32.5%, p<0.001) and hypercholesterolemia (46.5% vs 35.6%, p=0.036). It was observed that obesity patients had higher rate of unhealthy behaviors, such as smoking (27.7% vs 16.4%, p=0.006) and alcohol drinking (29.7% vs 19.9%, p=0.027). Although obesity was not confirmed as an independent risk factor for IgAN patients, we found that IgAN patients with obesity presented with higher incidence of hypertension, as well as lower event-free renal survival rate (logrank p < 0.001), especially in patients with 24-h urine protein = 1g (log-rank p =0.002). In addition, the synergy index showed that there was positive interaction between obesity and hypertension in IgAN. Conclusion: Obesity is an important risk factor for IgAN patients when combined with hypertension. Hypertension appears to be common in obese IgAN patients. [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.

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.

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]

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]

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 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]

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: 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]

Aim/Background: Several branded pharmaceuticals and generic medicines are available in the market for the management of End-Stage Renal Disease (ESRD) as a supportive care, and clinicians are unaware of the cost minimization and cost consequences aspects of these medications. Thus, this study aimed to compare the prices of branded versus generic medicines for ESRD treatment and to present the cost savings with a generic alternative. Materials and Methods: A prospective observational study was conducted among ESRD patients from three different tertiary care teaching hospitals in South India. The cost of branded pharmaceuticals were determined using the most recent current index of medical specialties, while the prices of generic medicines were accessed using the Pradhan Mantri Bhartiya Jan Aushadhi Pariyojana scheme, 2022. Results: The data were collected from 385 patients with ESRD. All Jan Aushadhi generic medicines were less expensive when compared to the branded medicines. The cost of ESRD medicines accessible in India varies greatly. The greatest difference in percentage cost savings were noted with amlodipine 5 mg tab (93.03%), voglibose 0.2mg/tab (88.10%), calcium carbonate + Vitamin D3 supplements 500 mg tab (80.27%), torsemide 10 mg tab (78.01%), and hematopoietic agent, erythropoietin 2000 U/inj (75.38%). Conclusion: The haematopoietic medicines and antidiabetic insulin injections were the most expensive medicines among the study population. Our research indicates that replacing the generic medicines with the branded medicines could help in reducing the cost burden. Healthcare professionals may consider prescribing generic medicines for cost-savings. [ABSTRACT FROM AUTHOR]

End stage renal disease (ESRD) is a significant health problem worldwide. Nearly 220000 patients are diagnosed with end stage renal disease every year, which calls for an additional demand of 34 million dialysis sessions in India. There is a rapid increase in the ESRD population worldwide. Furthermore approximate 70% of those who starts dialysis in India given up dialysis due financial constraints or death. Considering the need of the Satellite haemodialysis unit (SHD) for ESRD patients, ‘A studyto develop a costing model for SHD unit” was undertaken. A prospective study was conducted in a tertiary care hospital.The aim of the research was to analyse the need of SHD unit among dialysis patients and to suggest costing model for the tertiary care hospital. The methodology involved survey to address the patients need and perception towards SHD unit, direct observation, informal interview, bottom –up approach of costing method to identify the various cost involved in SHD unit and expert opinions. A total sample size of 120 ESRD patients in in - centre dialysis unit was selected for the study. As per the survey 30 patients need satellite haemodialysis unit. The study provides a cost analysis of 5 bedded SHD unit in the chosen tertiary care hospital. The author provides costing model recommendation for the development of SHD unit based on interpretation of data and expert opinions. [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).

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]

Background: Inadequate health literacy (HL) in dialysis patients increases the risk of poor self-care and decreases severe self-care and severe negative health outcomes in these patients. This study aimed to investigate HL and its related factors in dialysis patients in Kerman, Iran, in 2021. Methods: This cross-sectional study was performed on 280 dialysis patients who referred to Kerman (Iran) dialysis centres. The participants were selected through multi-stage sampling method. The study was conducted using the Iranian Health Literacy Questionnaire (IHLQ). The higher score shows a better HL. Results: The mean age of the subjects was 57.75±13.87 years. The mean score of HL was 9.12±4.54 out of 20 points. During multivariate regression, there was a significant relationship between HL and age (β=-0.08, P=0.02) and level of education (elementary/ literacy (β=4.607, P<0.001), middle school (β=6.38, P<0.001), high school (β=8.573, P<0.001) and academic education (β=9.410, P<0.001), and there was a significant relationship between HL and eye disease (β=-0.903, P=0.001). Conclusion: Most participants did not have adequate HL, while HL as the most important determinant of self-care can improve patients’ quality of life and reduce their health care costs. Therefore, in order to increase self-care, planning and necessary interventions, the HL of these patients seems to be necessary. [ABSTRACT FROM AUTHOR]

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). Aim of the Work: to evaluate thyroid abnormalities in patients with end stage renal disease in a sample of Egyptian populations. Patients and Methods: This study was conducted with 70 Egyptian Patients selected from Nephrology department in Theodor Bilharz Research Institute, in a case control study, they were categorized into 2 groups Group 1: Stage V renal disease group (n = 40): patients with eGFR <15mL/min with no history of thyroid disease or receiving any thyroid medications. Group 2: Age and sex matched health population group (n = 30): 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 end stage group, the difference statistically were significant only in muscle weakness. TSH was statistically significantly higher in cases with hypothyroidism. TGABs were statistically significantly higher in cases with hypothyroidism. Antimicrosomal antibodies recorded only in hypothyroid cases, the differences were statistically significant. FT3, TSH, TGABs and thyroid volume statistically had perfect diagnostic performance in diagnosing hypothyroidism among end stage renal disease group. Conclusion: Frequency of hypothyroidism was higher in end stage renal disease patients compared to control group. So, it is important to keep monitoring thyroid functions in patients with advanced renal impairment that may enhance quality of life. [ABSTRACT FROM AUTHOR]

Infection‐related hospitalization during the peri‐dialysis period (PDP) in patients with end‐stage renal disease (ESRD) has received less attention. Considering the limited data, we explored the risk factors in this population. Retrospective analysis using the data system to examine factors for infection in ESRD during PDP between January 2012 and December 2017. Patients were divided into infected group and non‐infected group according to the history of infection. Binary Logistic Regression Model was used to search for risk factors. A total of 478 patients were hospitalized during their PDP. One hundred and ninety patients developed infection (39.75%). Thirty‐six patients (18.95%) had two or more infection events, all due to recurrent respiratory infections. The respiratory system was the main site of infection (63.68%), followed by the urinary system and digestive system. Compared with the non‐infected group, the infected group had more patients with hypoproteinemia and coronary heart disease. The following factors: C‐reactive protein >15 mg/L, procalcitonin >1 ng/L, neutrophil percentage >75%, age >52.5 years, platelet >300 × 109/L, neutrophil to lymphocyte ratio, and concomitant coronary heart disease were associated with the occurrence of infection in ESRD patients during PDP. Patients with ESRD have a high incidence of infection during the PDP, with respiratory infection most commonly seen. This research identified several factors associated with risk for infection, which should guide the design of infection prevention strategies. [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.

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]

Background: Adherence of patients with End-Stage Renal Disease (ESRD) to Hemodialysis (HD), prescribed medications, diet and fluid restrictions is essential to get the desirable outcome and prevent complications. During COVID-19 pandemic, ESRD patients became more concerned with attending the HD sessions and following the protective measures because of the potential for increased susceptibility to COVID-19. The aim of this study was to evaluate the impact of the pandemic on patients' adherence to HD and medical regimens.Methods: Two hundred five ESRD patients on HD were interviewed with the ESRD Adherence Questionnaire (ESRD-AQ) and the Fear-of-COVID-19 Scale (FCV-19S). Clinical and laboratory correlates of adherence were retrieved from patients' records.Results: Self-reported adherence to HD showed that 19.5% were not adherent to HD during the pandemic compared to 11.7% before the pandemic (p < 0.001), with a significant agreement with the actual attendance of HD sessions (Kappa = 0.733, p < 0.001). Twenty-five patients (12.2%) had a history of COVID-19. The FCV-19S had a mean score of 18.8 and showed significant positive correlations with the pre-dialysis phosphorus and potassium. Multivariate analysis showed that the main predictors of non-adherence were the history of COVID-19, understanding and perception scores, and the Fear-of-COVID score.Conclusions: The COVID-19 pandemic adversely affected the adherence of ESRD patients to HD and medical regimen. Strategies to mitigate patients' fears of COVID-19 and improve their understanding and perceptions of adherence to HD and medical regimen should be adopted in HD centers during the pandemic.

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: 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]

The gut microbiota has nutritional and protective functions. In patients with end-stage renal disease, changes in the gut microbiota disrupt their protective functions. Probiotics help maintain normal bowel function. However, their role in patients with end-stage renal disease is controversial. We investigated whether Clostridium butyricum affects the nutrition and immune function of patients with end-stage renal disease undergoing maintenance dialysis between 2014 and 2015; thirty-seven patients were included. The patients were divided into two groups: one in which C. butyricum was administered and one in which it was not. One tablet of the probiotics, which contained 20 mg of C. butyricum, was administered orally three times daily for 2 years in the C. butyricum group. The 16S rRNA genes were sequenced from stool samples of 14 (37.8%) patients in the C. butyricum group and 23 (62.2%) patients in the control group. The differences in the gut microbiota of the two groups were analyzed. The α-diversity index indicated that the C. butyricum group had significantly more operational taxonomic units and higher albumin and transferrin levels than the control group. The effector to target cell ratio was significantly higher in the C. butyricum group. In addition, interleukin-6 levels were significantly lower in the C. butyricum group, and inflammation was less severe in this group. The patients undergoing maintenance dialysis with C. butyricum had abundant gut microbiota. They also had a good nutritional status, low systemic inflammation, and a good immunological status.

Long‐term dialysis involves a chronic inflammatory state and produces a high prevalence of vitamin D deficiency. A clinical trial was conducted in hemodialysis with serum 25‐hydroxyvitamin D (25[OH]D) level <30 ng/ml. The conventional‐group (N = 35) and the high‐dose group (N = 35) were treated with ergocalciferol according to the K/DOQI guidelines and double dosage of ergocalciferol from the recommendation for 8 weeks, respectively. The main outcomes were measured by serum 25[OH]D and interleukin‐6 (IL‐6). At the end of 8 weeks, a statistically significant greater increase was observed of mean serum 25[OH]D levels and a decrease of mean parathyroid hormone levels in the high‐dose group compared with the conventional‐dose group. The high dose group had the higher achievement of vitamin D sufficiency than the conventional‐dose group (97.4% vs. 76.4%, p = 0.012). No significant difference was found in mean changes of serum IL‐6 level in both groups, except subgroup patients with vitamin D deficiency or serum 25[OH]D <20 ng/ml, high dose treatment suppressed serum IL‐6 level (−2.67 pg/ml [IQR −6.56 to −0.17], p = 0.039). No differences were observed between the two groups in adverse events. Oral high‐dose ergocalciferol supplementation has achieved higher vitamin D sufficiency than standard dose in end stage renal disease patients on dialysis. [ABSTRACT FROM AUTHOR]
