Abstract
Glomerular injury secondary to infection is a well-documented phenomenon. While the incidence of classic acute post-streptococcal glomerulonephritis (APIGN) has declined in developed countries over the past few decades, IgA-dominant infection-associated glomerulonephritis (IgA PIGN) is emerging as a distinct renal pathology [1]. Characterized by predominant deposition of IgA antibodies within the glomeruli following infection, IgA-dominant PIGN differs from classic PIGN, which typically involves IgG and C3 deposits. This condition is often associated with staphylococcal infections and carries a poor prognosis. It commonly affects older adults and presents with reduced glomerular filtration rate and heavy proteinuria. Due to its rarity and overlapping clinical features with other glomerular diseases, IgA PIGN can be challenging to diagnose, often progressing to end-stage renal disease (ESRD) in approximately 80% of cases [3]. Prompt diagnosis and management, often requiring renal biopsy, are crucial for improving outcomes. Here, we present a case of IgA-dominant postinfectious glomerulonephritis.
