Prevalence of Hepatitis C Virus Infection and Efficacy of Sofosbuvir-Velpatasvir and Sofosbuvir-Daclatasvir Treatment Regimens in End-stage Renal Disease Patients on Maintenance Hemodialysis.

Patients with end-stage renal disease (ESRD) are at an increased risk of hepatitis C virus (HCV) infection. This study evaluated the prevalence of HCV infection in patients with ESRD on maintenance hemodialysis (MHD) and studied the effectiveness of sofosbuvir-velpatasvir and sofosbuvir-daclatasvir regimens in these patients. This study included patients with ESRD on MHD between January 2019 and December 2021 who were screened for HCV serology status. HCV-positive patients received sofosbuvir-velpatasvir or sofosbuvir-daclatasvir. Efficacy was assessed by the sustained virological response (SVR), and safety assessments included monitoring adverse events and laboratory parameters. Out of 1330 patients, 188 patients (14.1%) were positive for anti-HCV, with Genotype 1 being the most common genotype. Of these, 106 patients were included. The majority were males (61.3%), and the mean age was 48.4 years. Hypertension (45.3%) was the most common cause of renal failure, followed by diabetes (31.1%). Most patients (63.2%) were positive for HCV in the first 2 years of their dialysis treatment. Out of 106 patients, only 54 had received blood transfusions. Ninety-four (88.7%) patients received sofosbuvir-velpatasvir, whereas 12 (11.3%) received sofosbuvir-daclatasvir. SVR at 12 and 24 weeks after stopping treatment was seen in all (100%) patients. Asthenia and fatigue were the most common adverse events (11.2%). No patients reported on-treatment virologic failure or discontinuation of treatment because of adverse events. The prevalence of HCV infection in this population was 14.1%, and treatment of HCV infection using sofosbuvir-velpatasvir or sofosbuvir-daclatasvir regimens was well tolerated and effective.

Idiopathic Nonlupus Full-House Nephropathy: Clinicopathological Presentation and Comparison with Lupus Full-House Nephropathy.

Full-house pattern on immunofluorescence (IF) on kidney biopsy in a patient without systemic lupus erythematosus is termed as nonlupus full-house nephropathy (FHN). In this study, we retrospectively compiled patients with nonlupus FHN and compared them with lupus FHN for clinicopathological presentation. We included patients with full-house IF patterns in renal biopsies collected from March 2007 to August 2018, clinical and histopathological data at the time of presentation were studied retrospectively. Treatment received and outcome at the end of follow-up was studied. Patients with nonlupus FHN who did not show any systemic disease (idiopathic group) were compared with a group of lupus nephritis patients. Of 178 patients, 34 had nonlupus FHN with 21 having idiopathic nonlupus FHN and 13 patients having secondary nonlupus FHN (membranous nephropathy, IgA nephropathy, postinfection glomerulonephritis). Males were more often in idiopathic nonlupus FHN patients than lupus FHN patients (P = 0.005). Kidney biopsies more often showed a mesangial (P = 0.0006) and less proliferative pattern of injury (P = 0.0002) and less intense C1q staining (P = 0.0001) in idiopathic nonlupus than lupus FHN. Clinically, idiopathic nonlupus FHN presented with more proteinuria (P = 0.0059) and less complement consumption (P = 0.001) than lupus FHN patients. Compared to lupus FHN, nonlupus has mainly nephrotic syndrome as clinical presentation. There was no difference in the clinical outcome between lupus FHN and idiopathic nonlupus FHN. Nonlupus FHN is not a very common condition and has less female involvement than in lupus FHN. Idiopathic nonlupus FHN has certain histopathological features with less C1q staining by IF, less frequent proliferative lesions and higher mesangial or membranous lesions by light microscopy compared to lupus FHN. Regarding outcomes, there is no significant difference between lupus FHN and idiopathic nonlupus FHN.

Histological patterns of renal diseases in children: A 12-year experience from a single Tertiary Care Center in North-East India.

This study was conducted to retrospectively investigate the indications for renal biopsy in the native kidneys of children and to analyze the pathological findings in a single tertiary care hospital in North-East India for the past 12 years. All children (≤18 years) who underwent renal biopsy at our hospital from March 2007 to April 2018 were included. Renal tissue specimens were studied under light and immunofluorescence microscopy. The study group included 254 patients (female 57%). The median age was 15 years (range 6-18 years). The most frequent indications for renal biopsy were nephrotic syndrome (NS) (53.9%), urinary abnormality in systemic disease (22.1%), nephritic syndrome (15.4%), asymptomatic hematuria (4.7%), significant proteinuria (3.1%), and unexplained renal failure (0.8%). On histopathological examination, primary glomerular diseases were the most frequent (68.9%) followed by secondary glomerular diseases (30.3%) and tubulointerstitial diseases (0.8%). The most common primary glomerular diseases were minimal change disease (26.8%), focal segmental glomerular sclerosis (12.2%), diffuse proliferative glomerulonephritis (9.1%), membranous nephropathy (8.7%), IgA nephropathy (8.3%), membranoproliferative glomerulonephritis (2%), and mesangioproliferative glomerulonephritis (2%). Lupus nephritis (LN) (29.5%) was the most common secondary glomerular disease. NS was the most common indication of renal biopsy, and LN was the most common histopathological diagnosis in children ≤18 years.

A Comparable Study on the Outcomes of Urgent Initiated Peritoneal Dialysis Versus Conventional Start, A Single Centre Study from North-East India.

INTRODUCTION: To avoid temporary hemodialysis, urgent initiated PD (UIPD) has been designed. In these patients, PD is initiated within 3 days after PD catheter placement. In this study, we evaluated the outcomes of UIPD in end-stage renal disease patients compared with the conventional start of PD. METHODS: This is a single-center observational study, comparing outcomes of UIPD to conventional initiation of PD. All patients diagnosed with ESRD from March 2013 to February 2019 and were willing for CAPD were recruited. In UIPD group treatment was initiated at day 2 of catheter insertion with a dialysate volume of 1000 mL per dwell for 2 hours gradually increased to 2000 mL per dwell volume by 8 to 10 days. RESULTS: During the study period, 98 patients were started on peritoneal dialysis in our hospital: 35 UIPD, 63 conventional PD. The mean age was 60.81 ± 13.04 years. 67% of patients were males with diabetes mellitus (32%) being the most common cause of CKD. Among the patients in UIPD, the mean age was 58.49 ± 16.1 years, while as in conventional group mean age was 62.10 ± 10.9 years. The Median follow-up time was 381 days. Technique survival was seen in 95 patients (96.9%). There was no difference in technique failure between UIPD vs conventional group. Total complications in our study occurred in 16 patients out of 98 patients during this period. There was no significant difference in the complication rates between the UIPD group and the conventional group. CONCLUSION: Our study showed that catheter patency, technique survival, and catheter-related complications were comparable between UIPD and conventional start peritoneal dialysis.

Prevalence of Nondiabetic Renal Disease in Patients with Type 2 Diabetes Mellitus with Clinicopathological Correlation: A Study from a Tertiary Care Center of Assam, India.

Diabetes mellitus is the most common cause of chronic kidney disease worldwide. The prevalence of nondiabetic renal disease (NDRD) among patients with type 2 diabetes mellitus (T2DM) varies widely. This study aimed to evaluate the renal biopsies performed on type 2 diabetic patients for suspicion of NDRD and to correlate clinicopathological findings. All T2DM patients aged > 18 years were included in this study, who had renal biopsy performed for the following reasons: recent-onset nephrotic syndrome, unexplained rapid deterioration of renal function, proteinuria not accompanied by retinopathy, and unexplained hematuria. Renal biopsy was analyzed by light microscopy and immunofluorescence. Based on biopsy findings, the patients were grouped into three: (i) isolated NDRD, (ii) NDRD ± diabetic nephropathy (DN), and (iii) isolated DN. A total of 140 patients were enrolled in this study. Recent-onset nephrotic syndrome was the most common indication for biopsy, followed by the presence of active urine sediment. Forty-two percent of the patients had isolated DN, while NDRD was seen in 34% and DN ± NDRD in 24%. Focal segmental glomerulosclerosis (FSGS) and IgA nephropathy were the most common causes of isolated NDRD, while chronic tubulointerstitial nephritis (CTIN) was common in NDRD plus DN. Short duration of diabetes, absence of diabetic retinopathy, and lower glycated hemoglobin were predictive of NDRD. NDRD was seen in 58% of the patients with atypical presentations. FSGS and CTIN were common in NDRD diseases. Judicious use of biopsy in diabetic patients with atypical presentation may help in the diagnosis of NDRD.

Association of IL1 beta gene polymorphism and allograft functions in renal transplant recipients :a case control study from Kashmir Valley.

BACKGROUND: Cytokines have been found to be the important mediators during renal graft outcome. Therefore, we designed this study to investigate the role of recipients' IL-1 ß promoter (-511) and IL-1 ß exon-5 (+3954) polymorphisms with the risk of graft outcome. METHODOLOGY: We enrolled one hundred recipients of living-related renal transplants together with the age and sex matched controls from the healthy population not having any renal abnormality for this study. Genotype frequencies of the IL-1 ß promoter (-511) and IL-1 ß exon-5 (+3954) were analyzed using PCR-RFLP technique. RESULTS: Our results revealed significant differences in the healthy control group and patient group in IL 1ß +3954 (p < 0.001). The frequency of variant type TT genotype was higher in RE group as compared to SGF and showed 4 fold risk of rejection (OR = 4.54, p < 0.069) although p value was not significant. The frequency of wild type CC genotype and CT was not significant (p value 0.89 and 0.74 respectively). CONCLUSION: Our findings suggest that there is a prevalence of mutated allele of IL-1 gene cluster in our population, which may be responsible for renal dysfunction.

Prevalence of dyslipidemia in school children of Kashmir valley.

AIM: Increased incidence of CVD has been observed in recent years in the Kashmir valley (North India). Since the risk factor development of the cardiovascular diseases (CVD) takes place during childhood, we undertook an epidemiological survey to assess the prevalence of dyslipidemia in the school children of Kashmir valley. MATERIALS AND METHODS: 1131 children of 5-19 years of age were selected and evaluated for BMI, cholesterol, TGs, LDL and HDL levels from different areas of Srinagar city (urban) region of the Kashmir valley from June 2011-June 2014. RESULTS: The frequency of dyslipidemia in Kashmiri children varied along the subjects. Hypertriglyceridemia was seen in 82.6% of the males and 47.6% of females in the age group of 5-9 years, 38.5% of males and 51.1% of females in the age group of 10-14 years and 24.7% of males and 35.9% of the females in the age group of 15-19 years. Low levels of HDL than normal were seen in 34.7% of males and 19% of females in the age group of 5-9 years. Similarly low HDL levels were seen in 17.9% of males and 15.5% of females in the age group of 10-14 years. The incidence of low HDL was also seen in 4.9% of males and 10.8% of females in the age group of 15-19 years. CONCLUSIONS: In the present study dyslipidemia was more common in centrally obese children and the most common component was high triglycerides and low HDL's. Female school children were at higher risk of developing CVD than males.
