Background: Lupus Nephritis (LN) occurs in approximately half of all patients with Systemic Lupus Erythematosus (SLE) and it is the most common cause of morbidity and mortality in patients with SLE. Factors associated with poor renal outcome vary among studies, and researches coming from Brazil are scarce. Objectives: To identify the prognostic factors associated to the development of Chronic Kidney Disease (CKD) and End Stage Renal Disease (ESRD) in LN patients followed in a tertiary hospital. Design and Settings: We conducted a retrospective cohort study set in a tertiary hospital in Fortaleza, Ceará, Brazil. Methods: We compiled a total of 214 LN patients diagnosed between 1983 and 2015. Data was collected from medical records and further analyzed using logistic regression. Results: LN prevalence was 53.9%. The cohort had a mean follow-up of 11.2 years (SD ± 7.2 years). At the end of follow-up, 93 of 197 patients (47.2%) had CKD, and 49 of 191 (25.6%) were on regular dialysis. The main factors associated for developing CKD after logistic regression analysis were the following predictors: hypertension (HR 2.80; 95% CI 1.30-6.01; p = 0.008), time between diagnosis of SLE and diagnosis of LN (HR 0.98; 95% CI 0.97-0.99; p = 0.009) and discontinuation of medications (HR 2.41; 95% CI 1.08-5.37; p = 0.03). Conclusion: Hypertension, discontinuation of medications, and time between diagnosis of SLE and diagnosis of LN are independent variables associated with the development of CKD and ESDR in our study.

Background: The effect of dialysis modality on the survival of end-stage renal disease patients is a major public health interest. Methods: In this retrospective cohort study, all adult end-stage renal disease patients receiving dialysis treatment in Sabah between January 1, 2007 and December 31, 2017 as identified from the Malaysian Dialysis and Transplant Registry were evaluated and followed up through December 31, 2018. The endpoint was all-cause mortality. The observation time was defined as the time from the date of dialysis initiation after the onset of end-stage renal disease to whichever of the following that came first: date of death, date of transplantation, date of last follow-up, date of recovered kidney function, or December 31, 2018. Weighted Cox regression was used to estimate the effect of dialysis modality. Analyses were restricted to patients with complete data on all variables. Results: 1,837 patients began hemodialysis and 156 patients started with peritoneal dialysis, yielding 7,548.10 (potential median 5.48 years/person) and 747.98 (potential median 5.68 years/person) person-years of observation. 3.1% of patients were lost to follow-up. The median survival time was 5.8 years (95% confidence interval: 5.4, 6.3) among patients who started on hemodialysis and 7.0 years (95% confidence interval: 5.9, indeterminate) among those who started on peritoneal dialysis. The effect of dialysis modality was not significant after controlling for confounders. The average hazard ratio was 0.80 (95% confidence interval: 0.61, 1.05) with hemodialysis as a reference. Conclusion: There was no evidence of a difference in mortality between hemodialysis and peritoneal dialysis.

Abstract Background and Aims Renal involvement is a severe manifestation of ANCA-associated vasculitis. Patients often progress to end-stage renal disease. The potential for renal recovery after a first flare has seldom been studied. Our objectives were to describe the evolution of the estimated glomerular filtration rate (eGFR) and identify factors associated with the change in eGFR between diagnosis and follow-up at 3 months (ΔeGFRM0–M3) in a cohort of patients with a first flare of pauci-immune glomerulonephritis. Methods This was a retrospective study over the period 2003–2018 of incident patients in the Nord-Pas-de-Calais (France). Patients were recruited if they had a first histologically-proven flare of pauci immune glomerulonephritis with at least 1 year of follow up. Kidney function was estimated with MDRD-equation and analysed at diagnosis, 3rd, 6th and 12th months. The primary outcome was ΔeGFRM0–M3. Factors evaluated were histological (Berden classification, interstitial fibrosis, percentage of crescents), clinical (extra-renal manifestations, sex, age) or biological (severity of acute kidney injury, dialysis, ANCA subtype). Results One hundred and seventy-seven patients were included. The eGFR at 3 months was significantly higher than at diagnosis (mean ± standard deviation, 40 ± 24 vs 28 ± 26 ml/min/1.73 m2, p < 0.001), with a ΔeGFRM0–M3 of 12 ± 19 ml/min/1.73 m2. The eGFR at 12 months was higher than at 3 months (44 ± 13 vs 40 ± 24 ml/min/1.73m2, p = 0.003). The factors significantly associated with ΔeGFRM0–M3 in univariate analysis were: sclerotic class according to Berden classification, percentage of interstitial fibrosis, percentage of cellular crescents, acute tubular necrosis, neurological involvement. The factors associated with ΔeGFRM0–M3 in multivariate analysis were the percentage of cellular crescents and neurological involvement. The mean increase in eGFR was 2.90 ± 0.06 ml/min/1.73m2 for every 10-point gain in the percentage of cellular crescents. ΔeGFRM0–M3 was not associated with the risks of end-stage renal disease or death in long-term follow-up. Conclusions Early renal recovery after a first flare of pauci-immune glomerulonephritis occurred mainly in the first three months of treatment. The percentage of cellular crescents was the main independent predictor of early renal recovery.

Introduction: Chronic kidney disease (CKD) progression assessed by estimated GFR from creatinine (eGFR-Cr) is a risk factor for cardiovascular disease and end-stage renal disease (ESRD) and has been proposed as a surrogate endpoint for clinical trials. It is unclear if CKD progression assessed by change in different filtration markers has similar risk associations with ESRD. Hypothesis: We hypothesized that percent change in novel kidney filtration markers (β 2 -microglobulin and cystatin C) over a 6-year period would be independently associated with increased risk of ESRD during 15 years of follow-up, similar to the risk seen with change in eGFR-Cr. Methods: We conducted prospective analyses of the ARIC study (N=9,703). β 2 -microglobulin, cystatin C, and creatinine were measured at study visits 1 (1990-92) and 2 (1996-98). Incident ESRD (kidney dialysis or transplant) was defined as entry into the U.S. Renal Data System registry between study visit 2 and September 30, 2011. Cox proportional hazards regression was used to estimate the association between percent change in filtration marker and incident ESRD, adjusting for demographics, kidney disease risk factors, and 1 st measurement of the filtration marker. Results: During a median follow-up of 13.1 years, there were 142 incident ESRD cases. Median eGFR-Cr was 97.3 mL/min/1.73 m 2 at 1 st measurement and 89.0 mL/min/1.73 m 2 at 2 nd measurement. Percent change in eGFR-Cr was moderately correlated with percent change in the inverse of β 2 -microglobulin (r = 0.34) and the inverse of cystatin C (r = 0.36). Progression of CKD (10-25% and >25% decline in filtration function) was associated with increased ESRD risk, with novel markers (β 2 -microglobulin, cystatin C) showing an association at least as strong as the creatinine and eGFR-Cr estimates (Table). Conclusions: CKD progression assessed using novel filtration markers is independently associated with ESRD risk, suggesting the potential utility of measuring change in β 2 -microglobulin and cystatin C in clinical trials.

ObjectiveTo examine whether lifestyle factors, including sedentary time and physical activity, could independently contribute to risk of end-stage renal disease (ESRD).Study designCase-cohort study.SettingSouth-eastern USA.ParticipantsThe Southern Community Cohort Study recruited ~86 000 black and white participants from 2002 to 2009. We assembled a case cohort of 692 incident ESRD cases and a probability sample of 4113 participants.PredictorsSedentary time was calculated as hours/day from daily sitting activities. Physical activity was calculated as metabolic equivalent (MET)-hours/day from engagement in light, moderate and vigorous activities.OutcomesIncident ESRD.ResultsAt baseline, among the subcohort, mean (SD) age was 52 (8.6) years, and median (25th, 75th centile) estimated glomerular filtration rate (eGFR) was 102.8 (85.9–117.9) mL/min/1.73 m2. Medians (25th–75th centile) for sedentary time and physical activity were 8.0 (5.5–12.0) hours/day and 17.2 (8.7–31.9) MET-hours/day, respectively. Median follow-up was 9.4 years. We observed significant interactions between eGFR and both physical activity and sedentary behaviour (p<0.001). The partial effect plot of the association between physical activity and log relative hazard of ESRD suggests that ESRD risk decreases as physical activity increases when eGFR is 90 mL/min/1.73 m2. The inverse association is most pronounced at physical activity levels >27 MET-hours/day. High levels of sitting time were associated with increased ESRD risk only among those with reduced kidney function (eGFR ≤30 mL/min/1.73 m2); this association was attenuated after excluding the first 2 years of follow-up.ConclusionsIn a population with a high prevalence of chronic kidney disease risk factors such as hypertension and diabetes, physical activity appears to be associated with reduced risk of ESRD among those with preserved kidney function. A positive association between sitting time and ESRD observed among those with advanced kidney disease is likely due to reverse causation.
