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 (O
3 ) 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]- Published

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.

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: 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.

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.

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]

Brain microbleeds are increased in chronic kidney disease (CKD) and their presence increases risk of cognitive decline and stroke. We examined the interaction between CKD and brain microhemorrhages (the neuropathological substrate of microbleeds) in mouse and cell culture models and studied progression of microbleed burden on serial brain imaging from humans. Mouse studies: Two CKD models were investigated: adenine-induced tubulointerstitial nephritis and surgical 5/6 nephrectomy. Cell culture studies: bEnd.3 mouse brain endothelial cells were grown to confluence, and monolayer integrity was measured after exposure to 5-15% human uremic serum or increasing concentrations of urea. Human studies: Progression of brain microbleeds was evaluated on serial MRI from control, pre-dialysis CKD, and dialysis patients. Microhemorrhages were increased 2-2.5-fold in mice with CKD independent of higher blood pressure in the 5/6 nephrectomy model. IgG staining was increased in CKD animals, consistent with increased blood-brain barrier permeability. Incubation of bEnd.3 cells with uremic serum or elevated urea produced a dose-dependent drop in trans-endothelial electrical resistance. Elevated urea induced actin cytoskeleton derangements and decreased claudin-5 expression. In human subjects, prevalence of microbleeds was 50% in both CKD cohorts compared with 10% in age-matched controls. More patients in the dialysis cohort had increased microbleeds on follow-up MRI after 1.5 years. CKD disrupts the blood-brain barrier and increases brain microhemorrhages in mice and microbleeds in humans. Elevated urea alters the actin cytoskeleton and tight junction proteins in cultured endothelial cells, suggesting that these mechanisms explain (at least in part) the microhemorrhages and microbleeds observed in the animal and human studies.

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 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).

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]

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.

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.

Background: We evaluated restenosis rates at the cephalic arch after percutaneous angioplasty and stenting procedures in patients with brachial artery to cephalic vein arteriovenous fistula (BCAVF) hemodialysis access.Methods: We used data from adult hemodialysis patients treated at a national network of 44 outpatient interventional facilities during Oct 2011-2015. We included data from patients with BCAVF who received an exclusive angioplasty, or stent with angioplasty, for treatment of cephalic arch stenosis and had ≥1 subsequent evaluation of the cephalic arch. Median percent restenosis per month at cephalic arch and days between encounters was calculated from the 1st index to 2nd procedure, and for up to 4 subsequent encounters. Analyses were stratified by intervention and device types.Results: We identified a cohort of 3301 patients (mean age 62.2 ± 13.9 years, 58.5% male, 33.2% white race) with a BCAVF who had an angioplasty, or stent, at the cephalic arch for an index and ≥ 1 follow-up procedure. Between the 1st index to 2nd procedure, patients who received an angioplasty (n = 2663) or stent (n = 933) showed a median decrease of 18.9 and 16.5% in luminal diameter per month and a median time of 93 and 91 days between encounters, respectively. Restenosis and day rates were similar for standard versus high-pressure angioplasties. Bare metal stents showed 10.1 percentage point higher restenosis rate compared to stent grafts. Restenosis rates and time to restenosis were relatively consistent across subsequent encounters.Conclusions: Findings suggest hemodialysis patients with a BCAVF who require an angioplasty or stent to treat a stenosis at the cephalic arch will have stenosis reformed at a rate of 18.9 and 16.5% per month after the first intervention, respectively. Findings suggest patients are at risk of having significant lesions at the cephalic arch within 3 months after the previous intervention. [ABSTRACT FROM AUTHOR]- Published

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.

Introduction: Chronic kidney disease is defined as structural or functional damage of the kidney persisting for three or more months. Studies have shown hypertension and diabetes as the leading causes of chronic kidney disease. The aim of this study is to find out the prevalence of end-stage renal disease patients undergoing haemodialysis in a tertiary care hospital. Methods: This was a descriptive cross-sectional study conducted among 96 patients undergoing haemodialysis from February 13, 2021 to April 4, 2021 in the hemodialysis unit of a tertiary care centre after receiving ethical clearance from the Institutional Review Committee (Reference number: 354). Convenience sampling was done and all patients older than 18 years who were on maintenance haemodialysis on an outpatient basis were included in the study. Data were collected using a self-administered questionnaire. Data were analysed using the Statistical Package for the Social Science version 22.0. Point estimate at 95% Confidence Interval was calculated along with frequency and percentages for binary data and mean with standard deviation for continuous data. Results: Among 96 patients undergoing haemodialysis, the prevalence of end-stage renal disease was 83 (86.45%) (79.60-93.30 at 95% Confidence Interval). The most common underlying condition was hypertensive nephropathy in 34 (40.96%) patients, followed by both hypertensive and diabetic nephropathy in 26 (31.33%) patients. Conclusions: The prevalence of end-stage renal disease in our study was higher when compared to similar studies conducted in similar settings. Early diagnosis and adequate treatment of hypertension and diabetes could be crucial to reducing the prevalence of the end-stage renal disease.

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: 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]

Introduction. Kidney transplantation is the treatment of choice in the majority of end-stage renal disease (ESRD) patients. However, most of the incident ESRD patients are not given the necessary information regarding kidney transplantation. The aim of this study was to evaluate awareness and knowledge about kidney transplantation in ESRD patients who were on dialysis. Methods. In this cross-sectional study, a total of 300 ESRD patients who underwent hemodialysis or peritoneal dialysis and could be eligible for kidney transplant, were included. A questionnaire with 15 multiple choice questions (MCQs) was designed to collect the data. SPSS version 16 was used for data analysis and a P value less than .05 was considered statistically significant. Results. Two hundred thirty-four patients participated in the study (response rate of 78%). Among them 58.1% were male with the mean age (SD) of 52.5 (12.1) years. The majority of the patients (94.0%) were on hemodialysis. About 87.6% wanted to receive kidney transplant; but despite the desire of the patients, this method was initially offered to about 11.5 % of the patients as a possible method of renal replacement therapy. Patients who had desire to receive kidney transplantation were significantly younger, male, married, employed, and had high level of education (P < .05). Conclusion. Although most of the patients wanted to receive a kidney transplant, it was initially offered to a small population. Age, gender, marital status, employment condition, and level of education were significant factors for the patient's tendency to receive a kidney transplant. [ABSTRACT FROM AUTHOR]

Introduction: Diabetes mellitus is the most common single cause of End Stage Renal Disease (ESRD). About 20-30% of patients with Type 1 Diabetes Mellitus (Type 1 DM) develop diabetic nephropathy as a serious complication which is the major cause of morbidity and mortality. Early identification of renal impairment is crucial to prevent the progression of nephropathy to a significant degree, because several interventions have greatest impact if initiated very early in the course of the disease. Aim: To study the correlation of microalbuminuria and serum cystatin C for the early prediction of renal impairment in patients with Type 1 DM. Materials and Methods: This was a cross-sectional study conducted from January 2016 to June 2016 on type 1 DM patients attending Diabetology Out Patient Department (OPD). According to the duration of diabetes, pateints were divided into two groups, Group I with <5 years and Group II with >5 years duration. The patients in each group were categorised as cases and controls, based on the Albumin Creatinine Ratio (ACR), serum urea, Creatinine, cystatin C, glycated haemoglobin (HbA1c), and urine ACR levels were estimated. Student's unpaired t test was used to compare the means between two independent groups. Pearson correlation coefficient was used to estimate the degree of correlation between two quantitative variables. Results: Cystatin C levels in cases (0.89±0.35) when compared to controls (0.67±0.26) in more than five years duration of type 1 DM found to be statistically significant (p <0.05) and positive correlation between cystatin C and ACR (r = 0.4, p<0.05) found to be statistically significant in more than five years duration. It indicates that serum cystatin C levels increases as the values of ACR increases. There was no significant difference in cystatin C levels in patients with less than five years duration of type 1 DM Conclusion: Serum cystatin C may be considered as an early predictor of renal impairment in type 1 DM patients with more than five years duration. However, in this study cystatin C carries no significance in less than five years duration of type 1 DM patients. [ABSTRACT FROM AUTHOR]

Background: Kidney involvement is common in antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). It tends to be aggressive, and in some patients, the kidney involvement may reach the criteria of acute kidney injury (AKI). Here, we aim to describe the clinical characteristics of these patients and find risk factors for poor outcomes. Methods: Patients diagnosed with AAV in our hospital from February 2003 to February 2017 were included. Those who reached the KDIGO AKI criteria were reclassified according to the KDIGO AKI stage. The clinical features of these patients were analyzed. Also, according to the variation of serum creatinine 3 months after AKI episode, patients were further divided into two groups: patients whose serum creatinine (Scr) level at the third month decreased by 30% or more from the peak Scr level was classified into G1 and others were classified into G2. Long-term renal and survival outcomes of these patients were analyzed with a Cox model. The renal endpoint was reaching end-stage renal disease (ESRD), and the survival endpoint was death. Nomograms were built based on cox models. Results: Of 141 AAV patients included, during the median follow-up period of 64.0 (IQR 34.8, 85.4) months, 36 (25.5%) patients reached renal endpoints, and 22 (15.6%) patients died. The median renal survival time was 35.9 (IQR 21.3, 72.6) months and the median survival time was 48.4 (IQR 26.8, 82.8) months. Multivariate analysis showed that poor recovery of Scr level at 90 days (P < 0.001, RR = 9.150, 95%CI 4.163–20.113), BVAS score (P = 0.014, RR = 1.110, 95% CI1.021–1.207), and AKI stage 3 (P = 0.012 RR = 3.116, 95%CI 1.278–7.598) were independent risk factors for renal endpoints; poor recovery of Scr level at 90 days (P = 0.010, RR = 3.264, 95%CI 1.326–8.035), BVAS score (P = 0.010, RR = 1.171, 95%CI 1.038–1.320) and age (P = 0.017, RR = 1.046, 95%CI 1.008–1.086) were independent risk factors for all-cause death. The c-index of nomograms is 0.830 for the renal outcome and 0.763 for the survival outcome. Conclusion: KDIGO AKI stage 3 is the risk factor for ESRD in AAV patients with AKI. The BVAS score and level of kidney function recovery at 90 days are the independent risk factors for both ESRD and all-cause death and are of predictive value for the outcome. [ABSTRACT FROM AUTHOR]

ARTERIAL catheterization , *HEMODIALYSIS patients , *CHRONIC kidney failure , *CENTRAL venous catheters , *TREATMENT delay (Medicine) - Abstract
Introduction: In End Stage Renal Disease (ESRD), the patient needs alternative treatments such as dialysis for survival. To perform hemodialysis, proper vascular access is required. At emergency situations, the Central Venous Catheters (CVC) are used; however, they are not ideal for long-term dialysis. Hence, the permanent methods of hemodialysis should be replaced as soon as possible. This study aimed to investigate the causes of delay in the establishment of permanent vascular access in patients undergoing hemodialysis in Guilan in 2014 to 2015. Methods: The study was performed on 420 patients with ESRD who had been undergone hemodialysis through a CVC for more than three weeks in Razi Educational Remedial and Research Center. Data collection was done through checklist and interviews with the patients. All information entered into the SPSS 21 and analyzed by descriptive and inferential tests. Results: Totally, 56.4% of patients were male and 25.5% were 61 to 70 years old. 42.1% had delay between 1 and 2 months. The most important predictors of delay were: Patient's unwillingness, high costs of surgery, patient's inadequate knowledge about the need to establish AVF (Arterio Venous Fistula), Patient's fear of risks of AVF, lack of proper insurance coverage, Old age, Lesions at the insertion site of vascular access and lack of access to a nephrologist. Conclusion: Promoting the patients scientific information about establishing a permanent vascular access can have a significant role in reducing the delays in establishing permanent vascular access.

Objective: To investigate the proportion of arterial stiffness in patients on twice weekly maintenance hemodialysis and the factors affecting it. Methodology: This observational study with a cross-sectional design was performed in the Haemodialysis Unit, Kidney and Hypertension Division, Dr. Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia. The study enrolled 83 End Stage Renal Disease (ESRD) patients undergoing hemodialysis two times a week for at least three months. Patients with acute disease were excluded from the study. Arterial stiffness was measured as pulse wave velocity (PWV) using SphygmoCor® with PWV cut-off of 10m/s. SPSS 21.0 was used as an analysis tool; descriptive and inferential statistics were applied where needed. Results: In the sample, 42 (50.6%) were male and 41 were female (49.4%). Among all participants, 22 (26.5%) patients were with arterial stiffness and 61 (73.5%) were without arterial stiffness. Factors independently affecting arterial stiffness were fasting glucose level (odds ratio 6.842 [CI95% 1.66-28.24]) and LDL level (odds ratio 4.887 [CI95% 1.59-16.58]). Conclusion: The proportion of arterial stiffness in ESRD patients undergoing hemodialysis two times a week was about one third of all patients. In factors affecting arterial stiffness among ESRD patients, fasting glucose level and LDL level were found to have higher odds. [ABSTRACT FROM AUTHOR]

Background: Public–private partnership (PPP) in hemodialysis delivery in Nigeria is a new concept. We set out to compare the performance of Specialist Hospital Sokoto's (SHS) renal center operating with this model with four other neighboring government-operated dialysis centers. Materials and Methods: We reviewed the 6-year records (May 2011 to April 2017) of Dialysis Center of SHS, operated under a PPP and compared some performance indicators with four government-operated dialysis centers over the same period. Comparisons were made using Chi-square and corresponding P values were reported accordingly. P < 0.05 was considered significant. Results: A total of 1167 patients' data were studied. Of these, 252 (21.6%) patients with end-stage renal disease were dialyzed at SHS. The SHS dialysis center experienced 5 months of interruption in dialysis service. Only 38 (15.1%) patients sustained dialysis beyond 90 days and 105 (41.7%) patients had more than three sessions of hemodialysis. Only one patient was referred for kidney transplant from the dialysis center during the review period. SHS performed better than Federal Medical Center and Sir Yahaya Hospitals in terms of service availability, duration on hemodialysis, and greater number of hemodialysis sessions (χ2 = 29.06, df = 3, P < 0.001). Conclusion: PPP has improved the availability of dialysis service, mean duration on dialysis, and mean number of dialysis sessions but did not improve the kidney transplant referral rate at SHS. There is a need to encourage the current arrangement in the Hospital as well as other centers offering similar partnerships. [ABSTRACT FROM AUTHOR]

Chronic kidney disease (CKD) is a growing problem among aging population, and the number of individuals at risk of end stage renal disease is rising. Part of the reason lies in incomplete understanding of the pathways underlying renal aging and kidney disease, as well as insufficient delivery of evidence-based treatment to elderly patients with CKD. This review aims to address these unsolved issues by delineating updated mechanisms of renal senescence and summarizing recent findings on key clinical aspects of CKD in the elderly. Challenges and obstacles in caring for older people with CKD are discussed, with an emphasis on modification of risk factors, prevention of acute kidney injury, stabilization of progression and decision on dialysis initiation.

The world prevalence of chronic kidney disease (CKD) stages 1 to 5 ranges from 11.7 to 15.1%. Incidence of fractures in patients with CKD stage 5 is 5-fold higher than that in the general population, which is related to mineral metabolism disorders, secondary hyperparathyroidism, and osteoporosis. By damaging multiple organs and systems, CKD triggers a whole pathological cascade. There are hematopoietic abnormalities, cell lineages, direct toxic effect on blood cell elements, with simultaneously increased risk of bleeding and a high and extremely high risk of thrombi formation and thromboembolic complications. Calcium and phosphorus metabolism disorders lead to calcification and mineralization of vasculature, myocardium and heart valves; progressive renal dysfunction affects the course of heart and vessel diseases, aggravating their clinical manifestations. Cardiovascular disorders become the main cause of death of such patients, and the development of pulmonary hypertension is associated with increased morbidity and mortality. At the same time, protein and energy deficiencies do occur, with disturbance of the acid-base balance, water and electrolyte balance; uremic toxins exert unhealthy effects on the gastrointestinal tract. Various extra-renal pathologies, specific pharmacokinetics, regimen and frequency of renal replacement therapy needed to maintain an adequate volume status make it necessary to thoroughly prepare the patients for surgery and define special requirement to perioperative management in arthroplasty. Currently, there are no guidelines on the perioperative management of this patient category. In this review article we consider specifics and particulars of preoperative, intraoperative and postoperative management of the end stage CKD patients during knee and hip replacement arthroplasties.

Background: The specific mechanism of cardiovascular and cerebrovascular vasculopathy in the context of end-stage renal disease has not been elucidated. In the present study, we investigated the clinical impact of myeloid-derived suppressor cells (MDSCs) on hemodialysis patients and their mechanism of action. Methods: MDSCs were tested among 104 patients undergoing hemodialysis and their association with overall survival (OS) and cardiovascular and cerebrovascular events was determined. Results: Hemodialysis patients presented a significantly higher level of monocytic MDSCs (M-MDSCs) compared to healthy controls. M-MDSC were tested 3 months after first testing among 103 hemodialysis patients, with one patient not retested due to early death. The repeated results of M-MDSC levels were consistent with the initial results. Patients with persistent high level of M-MDSCs presented decreased OS, as well as increased stroke and acute heart failure events. As illustrated by multivariate Cox regression, M-MDSC was an independent predictor for OS and stroke events of hemodialysis patients. T cell proliferations were significantly abrogated by hemodialysis-related M-MDSCs in a dose-dependent manner. Besides, M-MDSCs presented higher levels of CXCR4 and VLA-4 compared to monocytes, which indicated their enhanced capability to be recruited to atherosclerotic lesions. The expression of arginase I and activity of arginase was also significantly raised in hemodialysis-related M-MDSCs. Human coronary arterial endothelial cells (HCAECs) presented increased capability to migration by coculture with M-MDSCs, compared with monocyte group. Arginase inhibitor and L-arginine abrogated the immune suppressive function and induction of HCAECs migration of hemodialysis related M-MDSC. Plasma IFN- γ , TNF-α and IL-6 were elevated in hemodialysis patients compared with healthy control. M-MDSC level was positively related to IL-6 level among hemodialysis patients. The plasma of hemodialysis patients induced M-MDSCs significantly compared with plasma from health donors. Besides, IL-6 neutralizing antibody significantly abrogated the induction. Neutralizing antibody of IFN- γ and TNF-α partially decreased the generation of arginase of the induced M-MDSC. Conclusions: M-MDSCs were elevated in ESRD patients under hemodialysis, and they exhibited a strong association with the risk of cardiovascular and cerebrovascular diseases. Hemodialysis related M-MDSC presented enhanced recruitment to atherosclerotic lesions, promoted the migration of endothelial cells through exhaustion of local L-arginine. [ABSTRACT FROM AUTHOR]

Although patients with severe renal impairment (SRI) typically experience more critical symptoms once infected with novel coronavirus, Severe Acute Respiratory Syndrome Coronavirus-2, this population has often been excluded from randomized controlled trials (RCT) for Coronavirus disease-2019 (COVID-19) treatment strategies. Of particular note, all RCTs for remdesivir (Veklury®), the only antiviral treatment approved by the Food and Drug Administration for COVID-19 intervention, excluded patients with an estimated glomerular filtration rate less than 30 ml/min. Regardless, some physicians have ventured to utilize this drug on patients with SRI, positing that the benefits might outweigh the risks of its use. The intent of this literature review was to examine the pharmacology of remdesivir and evaluate the published clinical literature on the topic to determine more definitively whether it might be safe to use in this population. A total of 59 articles were evaluated, seven of which contained descriptions of SRI patients treated with remdesivir for COVID-19, for a total of 176 patients. Interestingly, none of the patients experienced severe adverse reactions attributable to the use of remdesivir, and none of the investigators recommended against its use. While there is not yet clear evidence to suggest improvement in mortality, decreased morbidity and duration of illness are likely to lower mortality rates among these patients. Therefore, these findings suggest that, for patients with SRI diagnosed with COVID-19, the benefits of using remdesivir likely outweigh the risks. RCTs are urgently needed to further elucidate outcomes among this population. [ABSTRACT FROM AUTHOR]

Introduction: Chronic Kidney Disease (CKD) has become a major health issue worldwide. CKD patients require Renal Replacement Therapy (RRT) throughout their life. Haemodialysis is one of the options for RRT. Arterio-Venous Fistula (AVF) creation is required for haemodialysis. The radio cephalic fistula is the initial option for creating vascular access. Fistula can be created by anastomosing cephalic vein to radial artery either by End-To-Side (ETS) or Side-To-Side (STS) techniques. Aim: To compare the efficacy rate of radio cephalic AVF using ETS or STS anastomotic methods. Materials and Methods: This was a retrospective analytical study conducted at SDM college of medical sciences and hospital, Dharwad from March 2017 to February 2020. A total of 43 CKD patients were enlisted for the above duration from the hospital records. These patients were included in the study since they underwent radio cephalic AVF creation. AVF creation at other anatomical sites for rest of the CKD patients was excluded. Out of 43 patients, 24 of them underwent ETS technique and 19 STS technique; 15 patients from the former group and 17 from the latter were followed-up for a period of three months. Eleven patients were lost to follow up. Demographic variables were analysed with frequency, mean and standard deviation. Its association with two different operative techniques was analysed using Fisher’s-exact test. Outcome of the two operative procedures was analysed using Student’s t-test. Results: Effectively 15 patients from ETS group and 17 from STS group were compared. Three (20%) in ETS group and 5 (29.41%) in STS group had primary failure. Mean of maturation time in weeks in ETS group was 4.73±2.73 weeks and in STS group was 5.29±3.75 weeks. Three months patency rate in ETS group was 12 (80%) and in STS group was 12 (70.58%). Student’s t-test was performed comparing the above parameters and no statistical significance was noted. Conclusion: Comparison of two techniques of radio cephalic AVF creation proves that both the techniques are beneficial with no superiority of one over other. [ABSTRACT FROM AUTHOR]

The role of the human microbiome in health and disease is becoming increasingly apparent. Emerging evidence suggests that the microbiome is affected by solid organ transplantation. Kidney transplantation is the gold standard treatment for End-Stage Renal Disease (ESRD), the advanced stage of Chronic Kidney Disease (CKD). The question of how ESRD and transplantation affect the microbiome and vice versa includes how the microbiome is affected by increased concentrations of toxins such as urea and creatinine (which are elevated in ESRD), whether restoration of renal function following transplantation alters the composition of the microbiome, and the impact of lifelong administration of immunosuppressive drugs on the microbiome. Changes in microbiome composition and activity have been reported in ESRD and in therapeutic immunosuppression, but the effect on the outcome of transplantation is not well-understood. Here, we consider the current evidence that changes in kidney function and immunosuppression following transplantation influence the oral, gut, and urinary microbiomes in kidney transplant patients. The potential for changes in these microbiomes to lead to disease, systemic inflammation, or rejection of the organ itself is discussed, along with the possibility that restoration of kidney function might re-establish orthobiosis.

One of the risk factor of cardiovascular disease in patients of maintenance hemodialysis is abnormalities in lipid profile. Deranged levels of cholesterol are related to increased risk of cardiovascular mortality and morbidity in hemodialysis patients. Objectives: To determine the frequency of dyslipidemia under going maintenance hemodialysis at BVH, Bahawalpur. Study Design: Cross Sectional study. Setting: Dialysis unit at Bahawal Victoria Hospital, Bahawalpur. Period: January to May 2019. Material & Method: A total of 220 patients who were undergoing maintenance hemodialysis at dialysis unit BVH, Bahawalpur were included in the study. Pre-dialysis blood samples were taken for assessment of Sr. Cholesterol (Total), Sr. Triglycerides & Sr. HDL and were sent to Chemical Pathology Lab of QAMC, Bahawalpur on same day for processing. Results: Out of 220 patients, most of the patients were male (66.8%), history of smoking was present in 7.3% & mean duration of dialysis was 27.12 + 25.85 months. The mean of Sr. Cholesterol (Total), Sr. Triglycerides, Sr. HDL were 155.51+37.72 mg/ dl, 135.54+89.27 mg/dl & 35.22+7.77 mg/dl respectively. Dyslipidemia was present in 80% of patients with most common being low HDL (71.8%). Conclusion: Patients of maintenance hemodialysis are having significant number of dyslipidemia leading to inflammation, accelerated atherosclerosis and increased cardiovascular events.

Background: The transition onto dialysis is a stressful time that affects both patients and their partners. Research suggests that psychological and interpersonal characteristics within the couple are related to how well they adapt to dialysis. The aim of this multi-phase, mixed methods study was to develop a measure, the Starting Dialysis Questionnaire (SDQ), that is applicable to both patients and their partners and assesses their own thoughts and feelings about these constructs.Methods: Data from semi-structured interviews with patients and their partners (n = 22 couples) were analysed using theoretical thematic analysis to identify and define constructs related to quality of life (QOL). Next, items addressing these constructs were derived from the interviews. Then, cognitive interviews were conducted with patients with chronic kidney disease and their partners (n = 5 couples) to assess the face validity and comprehensibility of the items. Lastly, preliminary psychometric properties were evaluated in a sample of patients preparing to start dialysis and their partners (n = 83 couples).Results: Three themes related to QOL were identified, namely dialysis expectations, accepting dialysis and dyadic relationship characteristics. The cognitive interviews refined the SDQ and established its face validity. Psychometric assessments indicated that overall the items performed well and did not show significant floor or ceiling effects. Good internal consistency was found within the three domains, and items correlated within the domains.Conclusions: The SDQ is a measure (34 items) that assesses key psychological and interpersonal factors in patients and their partners as they start dialysis. It shows good preliminary psychometric properties; however, a large-scale field trial is needed to establish its validity. Once validated, it could offer a clinically useful tool to assist clinicians in preparing patients and partners for dialysis. [ABSTRACT FROM AUTHOR]- Published
