Abstract Background Acute kidney injury (AKI) in patients with multisystem inflammatory syndrome (MIS), COVID-19 related infection has been increasingly recognized a paucity of data on AKI incidence, mortality, and the requirement renal replacement therapy children MIS (MIS-C). Methods This is retrospective study evaluating prevalence, severity, management outcomes cohort Egyptian MIS-children (MIS-C) post-COVID infection. Patients were included if they met criteria for MIS-C based CDC guidelines. All evaluated diagnosis staging according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. Results Between March 2021 June 2023, total 655 confirmed cases admitted then followed up our hospital, whom 138 (21%) diagnosed MIS-C. Fifty-one developed associated infection, 42 analysis. Thirty-one had formerly healthy kidney, 51% (16 patients) classified as KDIGO stage 3, 5 needed hemodialysis 13 mechanical ventilation. Higher WBCs count, serum ferritin admission more severe (KDIGO 3) ( p = 0.04), while multivariate analysis showed high be independent predictor 0.02). Two (2/31) died during hospital admission, no residual impairment was reported at time discharge previously normal functions. Conclusion More than one-third develop AKI. Avoidance nephrotoxic drugs, early recognition, prompt AKI, including well-timed commencement dialysis cases, favorable outcomes.

COVID-19 infection causes collapse of glomerular capillaries and loss podocytes, culminating in a severe kidney disease called COVID-19–associated nephropathy (COVAN). The underlying mechanism COVAN is unknown. We hypothesized that cytokines induced by trigger expression pathogenic APOL1 via JAK/STAT signaling, resulting podocyte phenotype. Here, based on 9 biopsy-proven cases, we demonstrated for the first time, to best our knowledge, protein was abundantly expressed podocytes endothelial cells (GECs) kidneys but not controls. Moreover, majority patients with carried 2 risk alleles. show recombinant SARS-CoV-2 acted synergistically drive through pathway primary human GECs, micro-organoids derived from carrier alleles, blocked JAK1/2 inhibitor, baricitinib. demonstrate cytokine-induced JAK/STAT/APOL1 signaling reduced viability organoid rescued Together, results support conclusion COVID-19–induced are sufficient COVAN-associated podocytopathy JAK inhibitors could block this process. These findings suggest may have therapeutic benefits managing cytokine-induced, APOL1-mediated podocytopathy.

COVID-19 can cause acute kidney injury and may or exacerbate chronic diseases, including glomerular diseases. SARS-CoV-2 infection of cells has been reported, but it remains unclear if viral causes disease. The most important in patients with include impaired renal perfusion immune dysregulation. Chronic disease, especially failure replacement therapy transplant, is associated markedly increased mortality. Persons severe disease have excluded from clinical trials therapies, so therapeutic approaches must be extrapolated studies without Some medications used to treat should avoided at reduced dosages transplant recipients.

Long COVID (LC), also referred to as Post COVID-19 Condition, Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), and other terms, represents a complex multisystem disease persisting after the acute phase COVID-19. Characterized by myriad symptoms across different organ systems, LC presents significant diagnostic management challenges. Central disorder is role low-grade inflammation, non-classical inflammatory response that contributes chronicity diversity observed. This review explores pathophysiological underpinnings LC, emphasizing importance inflammation core component. By delineating pathogenetic relationships clinical manifestations this article highlights necessity for an integrated approach employs both personalized medicine standardized protocols aimed at mitigating long-term consequences. The insights gained not only enhance our understanding but inform development therapeutic strategies could be applicable chronic conditions with similar features.

Two variant alleles of the gene apolipoprotein L1 (APOL1), known as risk variants (RVs), are a major contributor to kidney disease burden in those African descent. The APOL1 protein contributes innate immunity and may protect against Trypanosoma, HIV, Salmonella, leishmaniasis. However, effects carrying 1 or more RVs contribute variety processes starting early utero can be exacerbated by other factors (or "second hits"). Indeed, these genetic variations interact with environmental exposures, infections, systemic modify health outcomes across life span. This review focuses on APOL1-associated diseases through life-course perspective discusses how exposure second hits impact long-term outcomes. APOL1-related typically presents adolescents young adults, individuals harboring likely progress failure than who lack APOL-1 RVs. Ongoing research is aimed at elucidating association RV adverse donor recipient transplant Unfortunately, there currently no established treatment for nephropathy.

The onset of coronavirus disease (COVID-19) as a pandemic infection, has led to increasing insights on its pathophysiology and clinical features being revealed, such noticeable kidney involvement. In this study, we describe the histopathological, immunofluorescence, ultrastructural biopsy-proven injury observed in series SARS-CoV-2 positive cases our institution from April 2020 November 2021. We retrieved retrospectively reviewed nine (two pediatric seven adults) that experienced nephrotic syndrome (six cases), acute clinically silent microhematuria leukocyturia. Kidney biopsies were investigated by means light microscopy, direct electron microscopy. primary diagnoses minimal change (four tubular necrosis collapsing glomerulopathy C3 (one case). None showed viral or viral-like particles analysis. Novel specific histologic biopsy related infection have been gradually disclosed reported, harboring relevant therapeutic implications. Recognizing properly diagnosing renal involvement patients experiencing COVID-19 could be challenging (due lack proof e.g., particles) requires proper integration pathological data.

Collapsing focal segmental glomerulosclerosis (FSGS), also known as collapsing glomerulopathy (CG), is the most aggressive variant of FSGS and characterized by a rapid progression to kidney failure. Understanding CG pathogenesis represents key step for development targeted therapies. Previous work implicated telomerase protein component TERT in pathogenesis, transgenic expression adult mice resulted resembling that seen human primary HIV-associated nephropathy (HIVAN). Here, we used telomerase-induced mouse model (i-TERTci mice) identify mechanisms inhibit pathogenesis. Inactivation WIP1 phosphatase, p53 target acting negative feedback loop, blocked disease initiation i-TERTci mice. Repression upon deficiency was associated with senescence enhancement required transforming growth factor-β functions.
