AI Article Synopsis

  • * A case study details a 66-year-old man with hepatitis C who developed MPGN and a 5-year-old boy who presented with aHUS after an infection, both sharing similar genetic variants.
  • * The findings suggest that low levels of factor H-related 5 (FHR-5) may increase susceptibility to infections, leading to different kidney disease manifestations.

Article Abstract

Dysregulation of the alternative complement pathway is a major pathogenic mechanism in two rare renal diseases: atypical haemolytic uraemic syndrome (aHUS) and membranoproliferative glomerulonephritis (MPGN). We report on a 66-year-old male with chronic hepatitis C virus (HCV) infection and a combined liver-kidney transplant that was diagnosed with MPGN at the age of 63 years and a 5-year-old boy who presented with aHUS at the age of 21 months following a infection. Both patients carried similar frameshift variants in the complement gene that segregate with reduced levels of factor H-related 5 (FHR-5). We conclude that low FHR-5 levels may predispose to viral and bacterial infections that then trigger different renal phenotypes.

Urine is an attractive biospecimen for noninvasive tests to facilitate bladder tumor diagnostics. Three different point-of-care (POC) tests based on lateral flow immunoassays (LFAs) are currently commercially available: UBC® Rapid Test, BTA stat®, and NMP22 BladderChek. The present review discusses these different tests based on their performance, clinical utility and the nature of the respective analytes.

Immune complexome analysis reveals an autoimmune signature predictive of COVID-19 severity.

Background: The factors contributing to the development of severe coronavirus disease 2019 (COVID-19) following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain unclear. Although the presence of immune complexes (ICs), formed between antibodies and their antigens, has been linked to COVID-19 severity, their role requires further investigation, and the antigens within these ICs are yet to be characterized.

Method: Here, a C1q enzyme-liked immunosorbent assay and immune complexome analysis were used to determine IC concentrations and characterize IC antigens, respectively, in the sera of 64 unvaccinated COVID-19 patients with PCR-confirmed SARS-CoV-2 infection, enrolled at seven participating centers in 2020.

Background: Complement Factor H-Related protein 5 (CFHR5) belongs to the factor H/CFHR family and regulates the complement system by modulating factor H's inhibitory activity against C3b. Despite its known role, the impact of CFHR5 on autoimmune arthritis and its relationship to pathophysiological changes in arthritis and bone loss remain unclear. This study aimed to assess the effect of CFHR5 on aggressive osteoclast activity and arthritis using a murine model of collagen antibody-induced arthritis (CAIA).

Article Synopsis
  • Hemolytic uremic syndrome (HUS) is a serious condition that can happen after an infection or due to problems in the body's immune system, and there are two types: typical and atypical.
  • This text discusses a 9-year-old boy who had a rare form of aHUS caused by specific genetic issues, which made his body produce autoantibodies that affected his kidneys and brain.
  • The study found that many kids with aHUS needed kidney treatment and that early treatment with special therapy may help prevent kidney failure, even if the patient has infections like STEC.
