Lupus Podocytopathy: An Overview
Publication date: September 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 5Author(s): Nestor Oliva-Damaso, Juan Payan, Elena Oliva-Damaso, Teresa Pereda, Andrew S. BombackIn systemic lupus erythematosus, nephrotic-range proteinuria typically signals the presence of a proliferative lupus nephritis (class III/IV) and/or membranous lupus nephritis (class V, with or without concomitant class III or IV lesions). However, in rare instances, systemic lupus erythematosus patients with nephrotic syndrome have kidney biopsy findings of normal glomeruli or focal segmental glomerulosclerosis lesions, with or without mesangial proliferation, on light microscopy; the absence of subepithelial or subendothelial deposits on immunofluorescence and electron microscopy; and diffuse foot process effacement on electron microscopy. This pattern, termed lupus podocytopathy, is a unique form of lupus nephritis that mimics minimal change disease or primary focal segmental glomerulosclerosis and represents approximately 1% of lupus nephritis biopsies. Here we review the clinical features, histological manifestations, diagnostic criteria and classification, pathogenesis, treatment, and prognosis of lupus podocytopathy.
Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...
Authors: Mosquera J, Pedreañez A Abstract Increasing evidence supports a central role of the immune system in acute post streptococcal glomerulonephritis (APSGN), but the current view of how streptococcal biology affects immunity, and vice versa, remains to be clarified. Renal glomerular immune complex deposition is critical in the initiation of APSGN; however, mechanisms previous to immune complex formation could modulate the initiation and the progression of the disease. Initial and late renal events involved in the nephritis can also be related to host factors and streptococcal factors. In this review we ...

CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]

We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN. PMID: 33028760 [PubMed - in process]
Conclusion: Isolated renal disease induced by hydralazine as part of drug-induced lupus is uncommon. Our patient developed isolated classic lupus nephritis after hydralazine therapy with no associated systemic vasculitis. Treatment required stopping the hydralazine and initiating systemic immunosuppressive therapy to achieve complete remission. PMID: 32612474 [PubMed]
CONCLUSIONS: This is the first study comparing CsA, MMF and AZA on long-term LN maintenance therapy. All treatments had similar efficacy in achieving and maintaining CRR, despite more severe baseline clinical features in patients treated with CsA. PMID: 32462476 [PubMed - as supplied by publisher]
Abstract Glomerular diseases are considered to be a significant cause of chronic kidney disease. Kidney biopsy continues to be an essential diagnostic tool. We review the renal biopsies which were done on children below the age of 14 years in the past 10 years (from January 2008 to September 2018) in a single tertiary pediatric hospital in Saudi Arabia to determine the patterns of renal disease among Saudi children as well-correlating clinical presentation with histopathological diagnosis. A total of 203 pediatric kidney biopsies were performed. The mean age was 7.3 ± 3.9 years (3 months to 14 years). There...
Conclusions: This data reflects that many of the renal diseases are preventable or potentially curable. Therefore, improvement of pediatric renal services and training of health workers would help in early detection and treatment of these conditions leading to reduction in their morbidity and mortality.
