We investigated the effect of two dosing regimens of oral iron on iron status and hematological parameters in patients with CKD. In this single center, open label, randomized, active controlled clinical trial, stable adult patients with CKD stage G3–4 with percentage transferrin saturation (%TSAT) ≤ 30% and serum ferritin ≤ 500 ng/ml were eligible. Participants were randomized to receive either 100 mg of ferrous ascorbate once daily (OD group) or 100 mg of ferrous ascorbate twice daily (BD group, total daily dose 200 mg). The primary outcome was change in %TSAT between groups over 12 weeks. The secondary outcomes were changes in other iron status and hematological parameters, serum interleukin-6 (IL-6) and hepcidin. 80 participants were enrolled out of which 76 completed the study. Change in %TSAT was not significantly different between groups (β = − 1.43, 95% CI − 3.99 to 1.12, BD group as reference). The rise in serum ferritin was less in the OD group as compared to BD group (β = − 0.36, 95% CI − 0.61 to − 0.10) whereas MCHC increased in the OD group as compared to decrease in the BD group (β = 0.37, 95% CI 0.067–0.67). These observations need exploration to ascertain the impact of different oral iron dosing strategies in CKD. [ABSTRACT FROM AUTHOR]

This article discusses the outcomes of primary membranous nephropathy (PMN) patients who are refractory to immunosuppressants. PMN is a common cause of adult-onset nephrotic syndrome, and current guidelines recommend immunosuppressive therapy. However, a significant proportion of patients do not respond to initial treatment and require rescue therapy. The article presents a systematic review of 18 observational studies that analyzed different rescue therapies for refractory membranous nephropathy. The findings suggest that rituximab, adrenocorticotrophic hormone, and obinutuzumab show promising results, but there is no clear winner. The choice of treatment should be based on individual patient characteristics and side effect profiles. Further controlled studies are needed to investigate these agents.

Summary: The burden of chronic kidney disease (CKD) has increased exponentially worldwide but more so in low- and middle-income countries. Specific risk factors in these regions expose their populations to an increased risk of CKD, such as genetic risk with APOL1 among populations of West African heritage or farmers with CKD of unknown etiology that spans various countries across several continents to immigrant/indigenous populations in both low- and high-income countries. Low- and middle-income economies also have the double burden of communicable and noncommunicable diseases, both contributing to the high prevalence of CKD. The economies are characterized by low health expenditure, sparse or nonexistent health insurance and welfare programs, and predominant out-of-pocket spending for medical care. This review highlights the challenges in populations with CKD from low-resource settings globally and explores how health systems can help ameliorate the CKD burden.

Introduction. Anti-Compliment Factor H antibody hemolytic uremic syndrome (AFH-HUS) is a common cause of paediatric atypical HUS in India. We wanted to study the outcome of patients receiving less than recommended plasma exchange (PLEX) but adequate immunosuppression, with respect to hypertension, preservation of renal function and proteinuria. Methods. A retrospective study was performed in 15 children admitted from 2016 to 2018 with AFH-HUS. Follow up details including physical examination, hematological parameters, renal function test and urine examination performed at 3, 6, and 12 months were noted. Risk stratification and staging for chronic kidney disease (CKD) were done according to the Kidney Disease Improving Global Outcomes (KDOQI) guidelines. Standard statistical tests which were appropriate were used. Results. Mean age of our study cohort was 7.8 ± 1.9 years. 14 children had hypertension. Mean nadir hemoglobin was 5.8 ± 1.0 g/dL and platelet = 58 ± 37.7 × 109 cells/L. Median anti factor H (AFH) level was 316 AU/mL (150 to 452). Hemodialysis was required in 7 children. Fourteen children received PLEX with a mean of 11 ± 6 cycles. Thirteen children received 6 cycles of intravenous cyclophosphamide. After six months, therapy was switched to mycophenolate mofetil in 4 children, steroids alone in 2 children and 9 children with azathioprine. On follow-up, risk of CKD reduced from 80% at 3 months to 26% at 12 months (P = .01). Only 40% patients had CKD stage 2 at the end of 12 months (mean eGFR = 95.0 ± 19.4 mL/min/1.73m2). Conclusion. The adequate number of PLEX needed in AFH-HUS needs further studies. Till such reports come, PLEX in recommended strategies or lesser, if not available, with immunosuppression in AFH-HUS can decrease progression to CKD. [ABSTRACT FROM AUTHOR]
