Objective We analyzed baseline and follow-up characteristics related to poorer renal outcomes in a Brazilian cohort of admixture race patients with lupus nephritis. Methods Overall, 280 outpatients with a diagnosis of systemic lupus erythematosus and previous kidney biopsy of lupus nephritis were recruited from August 2015 to December 2018 and had baseline laboratory and histologic data retrospectively analyzed; patients were then followed-up and data were recorded. The main outcome measure was the estimated glomerular filtration rate at last follow-up. Secondary analyses assessed the impact of initial kidney histology and treatment in long-term kidney survival. Results Median duration of lupus nephritis was 60 months (interquartile range: 27–120); 40 (14.3%) patients presented progressive chronic kidney disease (estimated glomerular filtration rate <30 and ≥10 ml/min/1.73 m2) or end-stage kidney disease at last visit. Adjusted logistic regression analysis showed that class IV lupus nephritis (odds ratio 14.91; 95% confidence interval 1.77–125.99; p = 0.01) and interstitial fibrosis ≥25% at initial biopsy (odds ratio 5.87; 95% confidence interval 1.32–26.16; p = 0.02), lack of complete or partial response at 12 months (odds ratio 16.3; 95% confidence interval 3.74–71.43; p < 0.001), and a second renal flare (odds ratio 4.49; 95% confidence interval 1.10–18.44; p = 0.04) were predictors of progressive chronic kidney disease. In a Kaplan-Meier survival curve we found that class IV lupus nephritis and interstitial fibrosis ≥25% were significantly associated with end-stage kidney disease throughout follow-up (hazard ratio 2.96; 95% confidence interval 1.3–7.0; p = 0.036 and hazard ratio 4.96; 95% confidence interval 1.9–12.9; p < 0.0001, respectively). Conclusion In this large cohort of admixture race patients, class IV lupus nephritis and chronic interstitial damage at initial renal biopsy together with non-response after 1 year of therapy and relapse were associated with worse long-term renal outcomes.

Abstract Purpose An increase in arterial stiffness is associated with rapid renal function decline (RFD) in patients with chronic kidney disease (CKD). The aim of this study was to investigate whether the radial augmentation index (rAI), a surrogate marker of arterial stiffness, affects RFD in individuals without CKD. Methods A total of 3165 Chinese participants from an atherosclerosis cohort with estimated glomerular filtration rates (eGFR) of ≥ 60 mL/min/1.73 m2 were included in this study. The baseline rAI normalized to a heart rate of 75 beats/min (rAIp75) was obtained using an arterial applanation tonometry probe. The eGFRs at both baseline and follow-up were calculated using the equation derived from the Chronic Kidney Disease Epidemiology Collaboration. The association of the rAIp75 with RFD (defined as a drop in the eGFR category accompanied by a ≥ 25% drop in eGFR from baseline or a sustained decline in eGFR of > 5 mL/min/1.73 m2/year) was evaluated using the multivariate regression model. Results During the 2.35-year follow-up, the incidence of RFD was 7.30%. The rAIp75 had no statistically independent association with RFD after adjustment for possible confounders (adjusted odds ratio = 1.12, 95% confidence interval: 0.99–1.27, p = 0.074). When stratified according to sex, the rAIp75 was significantly associated with RFD in women, but not in men (adjusted odds ratio and 95% confidence interval: 1.23[1.06–1.43], p = 0.007 for women, 0.94[0.76–1.16], p = 0.542 for men; p for interaction = 0.038). Conclusion The rAI might help screen for those at high risk of early rapid RFD in women without CKD.

Background: Meeting place-of-death preferences is an important measure of the quality of end-of-life care. Systematic review shows that 42% of end-stage kidney disease patients prefer home death. Little research has been undertaken on place of death. Aim: To understand patterns of place of death in patients with end-stage kidney disease known in one UK renal unit. Design: A retrospective cohort study of all patients with chronic kidney disease stage 4–5, age ⩾75 and known to one UK renal unit, who died between 2006 and 2012. Patients were categorised into three management pathways: haemodialysis, conservative and pre-dialysis. Results: A total of 321 patients (mean age, 82.7; standard deviation, 5.21) died (61.7% male). In all, 62.9% died in hospital (95% confidence interval, 57.5%–68.1%), 21.8% died in their usual place of residence (95% confidence interval, 17.5%–26.6%) and 15.3% died in an inpatient palliative care unit (95% confidence interval, 11.6%–19.5%). Management pathway and living circumstances were most strongly associated with place of death. Patients on the conservative pathway had four times the odds of dying out of hospital (odds ratio, 4.0; 95% confidence interval, 2.1–7.5; p < 0.01). Patients living alone were less likely to die out of hospital (odds ratio, 0.3; 95% confidence interval, 0.1–0.6; p < 0.01). There were also changes in place of death over time, with more patients dying out of hospital in 2012 compared to 2006 (odds ratio, 3.1; 95% confidence interval, 1.0–9.7; p < 0.05). Conclusion: Most patients with end-stage kidney disease die in hospital, but patients managed without dialysis are significantly more likely to die outside of hospital. Planning ahead is key to be able to meet preference for place of death.

Objective To evaluate long-term mortality and end-stage renal disease (ESRD) in a cohort of Norwegian patients with biopsy-proven lupus nephritis (LN). Methods Renal biopsies were obtained from 178 patients with LN from 1988 until 2007. Mortality rate and death causes were provided by Statistics Norway and ESRD data were provided by the Norwegian Renal Registry. Risk factors for all-cause mortality were evaluated by Cox regression. Standardized mortality ratio (SMR) was compared to observed deaths in a matched general population sample. Results Mean age was 37.6 (±14.4) years, and median time of follow-up was 8.5 years (0–26.2). Thirty-six patients (20.2%) died during follow-up. The SMR for all-cause mortality was 5.6 (Confidence interval [CI] 3.7–7.5). In an adjusted multivariate analysis proliferative glomerulonephritis (LN class IV) was independently associated with all-cause mortality; hazard ratio (HR) 2.6 (Confidence interval [CI] 1.2–5.7 p = 0.017). Main causes of death were infections (47.2%) and cardiovascular events 8 (22.2%). Thirty-six patients (20.2%) reached ESRD. Conclusions Biopsy-proven LN is associated with increased mortality compared to the general population. LN class IV is associated with all-cause mortality. Infections and cardiovascular events were the most common causes of death. Patients with LN have a high incidence of ESRD.

Background: Focal segmental glomerulosclerosis (FSGS) is a heterogeneic glomerular disease. Risk factors for end- stage kidney disease (ESKD) and impact of immunosuppression treatment (IST) has varied in previously published cohorts. These cohorts were limited by relatively small case numbers, short follow up, lack of racial/ethnic diversity, a mix of adult and pediatric patients, lack of RAAS inhibition, or lack of subgroup analysis of IST. Methods: We compared demographics, clinical characteristics, histopathology and IST to long term renal survival in a large, ethnically diverse, adult cohort of 338 biopsy-proven FSGS cases with long term follow up in the era of RAAS inhibition using data from the United States Department of Defense health care network. Results: Multivariate analysis showed that nephrotic range proteinuria (NRP), estimated glomerular filtration rate <60 ml/min/1.73m2, hypoalbuminemia, interstitial fibrosis and tubular atrophy, and interstitial inflammation at diagnosis as well as the absence of remission were all associated with worse long term renal survival. IgM, C3, and a combination of IgM/C3 immunofluorescence staining were not associated with reduced renal survival. IST was not associated with improved renal survival in the whole cohort, or in a subgroup with NRP. However, IST was associated with better renal survival in a subgroup of FSGS cases with both NRP and hypoalbuminemia and hypoalbuminemia alone. Conclusion: Our study suggests that IST should be reserved for FSGS patients with nephrotic syndrome. It also introduces interstitial inflammation as a potential risk factor for ESKD and does not support the proposed pathogenicity of IgM and complement activation.

Abstract Background and Aims Lupus nephritis (LN) poses a considerable impact on the morbidity and mortality of SLE patients. Long term comparative outcome data with cyclophosphamide (CYP) and mycophenolate mofetil (MMF) based regimen from the Indian subcontinent is sparse. We assessed the renal and patient survival of these patients for the types of induction CYP or MMF and the two maintenance therapies – MMF or Azathioprine. We determined the predictors of death and dialysis dependency in the study population. Method In this retrospective study, we analysed outcomes of 100 LN patients, total 67 (26 class III, 25 class IV, 6 class III+V, and 10 class IV+V)) treated with CYP (euro lupus-40 and NIH- Dharmendra Bhadauria 27), and 33 with MMF based regimen with the steroid between July 2008 to June 2018. The class distribution of the patients in the two groups was similar. The data were archived regarding demography, clinical, histopathological features, and the treatment given of all 100 biopsy-proven LN patients. Outcomes between two regimens CYP and MMF in terms of remission, dialysis dependency, and patient survival were compared. The renal survival and patient survival at the end of follow-up between two groups were also analysed. Results The clinical characteristics were similar in both groups, except the activity index was high in CYP patients (6.13 ±4.48 Vs. 4.61 ± 2.80); however, the chronicity index was similar. The overall remission was 70% at the end of induction. The CR, PR, and NR in the CYP group was 46.2%, 23.9 %, 29.9% respectively; however, in the MMF group was 57.6%, 12.1%, and 30.3%, respectively. More patients died in CYP (14.9%) than those in MMF (9.1 %) patients. The 1-, 2-, 3-, 4-, 5- and 10-years patient survival in the CYP induction was 89.5%, 86.2%, 86.2%,83.8%, 83.8% and 83.8% however in MMF was 93.9%, 93.9%, 89%, 89%, 89% and 89% respectively. The most common cause of death was sepsis 9/13(69.2%), followed by uremia. The high serum creatinine, low Hb, male, thrombocytopenia, microscopic haematuria, leukocyturia, nephrotic proteinuria, lack of remission in 12 months, dialysis, doubling of creatinine on follow-up were significant predictors of mortality. The 1-, 2- 3-, 4-, 5- and 10- years renal survival (event death-censored, but dialysis dependency) in CP group was 98.5%, 96.7%, 94.7%, 92.4%, 92.4% and 84 % respectively however in the MMF was 96.8 %, 96.8%, 91.9%, 91.9%, 91.9%, and 78.8% respectively. (Figure 1)At the end of the study, dialysis dependency in the MMF group and CYP group was 7.5% and 12.1 %, respectively (NS). In the maintenance therapy, 3/56(5.3%) had to double of creatinine in MMF, and 7/34 (20.5%) in the AZA group (p=0.03). Conclusion Long term outcomes in terms of patient and renal survival of LN patients treated with CP and MMF based induction is similar. Serum creatinine doubling was more with MMF than AZA based maintenance. The majority of death occurred during induction, and sepsis was the most common cause of death.

BackgroundThe very long-term consequences of absence of remission in lupus nephritis (LN) remain understudied.MethodsIn this retrospective analysis, we studied a selected cohort of 128 patients with biopsy-proven class III, IV or V incident LN followed for a median period of 134 months (minimum 25). Remission was defined as a urine protein to creatinine (uP:C) ratio <0.5 g/g and a serum creatinine value <120% of baseline. Renal relapse was defined as the reappearance of a uP:C >1 g/g, leading to a repeat kidney biopsy and treatment change. Poor long-term renal outcome was defined as the presence of chronic kidney disease (CKD).ResultsTwenty per cent of patients never achieved renal remission. Their baseline characteristics did not differ from those who did. Absence of renal remission was associated with a threefold higher risk of CKD (48% vs 16%) and a 10-fold higher risk of end-stage renal disease (20% vs 2%). Patients achieving early remission had significantly higher estimated glomerular filtration rate (eGFR) at last follow-up compared with late remitters. Accordingly, patients with CKD at last follow-up had statistically longer time to remission. Among patients who achieved remission, 32% relapsed, with a negative impact on renal outcome, that is, lower eGFR values and higher proportion of CKD (33% vs 8%).ConclusionEarly remission should be achieved to better preserve long-term renal function.

Despite a superior quality of life and a favorable cost effectiveness, it has not been well established thus far whether renal cadaveric transplantation contributes to superior survival probability of end-stage renal disease patients in Europe, because the mortality rate on dialysis is lower compared with the United States. This analysis was undertaken to compare the mortality of wait-listed patients and transplant recipients during long-term follow-up, including the possibility of a retransplant in a single-center study. The study cohort included 309 consecutive patients, ages 17 to 72 yr, being registered on the waiting list of the Renal Transplantation Center of Mannheim since the initiation of the transplantation program on June 3, 1989. Follow-up was terminated on September 30, 1997, with a mean of 4.15 yr. A total of 144 renal cadaveric transplants (four retransplants) was performed during the follow-up period. A Cox regression model considering the time-dependent exposure to the different therapy modalities was applied for statistical analysis. Patients being removed from the waiting list or coming back to dialysis after transplantation were censored at time of withdrawal or graft failure. Transplantation resulted in a lower hazard ratio, which was 0.36 (95% confidence interval, 0.15 to 0.87) when the hazard of the wait-listed group was taken as 1.00. The underlying incidence rate of death was 0.026 per patient-year (0.032 on dialysis versus 0.016 with functioning graft). Performing the evaluation on an intention-to-treat basis without censoring the lower risk of the transplanted group was still pronounced according to a hazard ratio of 0.44 (95% confidence interval, 0.22 to 0.89). Thus, patients receiving a renal cadaveric transplantation have a substantial survival advantage over corresponding end-stage renal disease patients on the waiting list even in the setting of a single transplantation center where mortality on regular dialysis therapy was comparatively low.
