What is a common post-infectious cause of acute glomerulonephritis?

IgA nephropathy, also known as Berger's disease, is a common post-infectious cause of acute glomerulonephritis. This condition typically follows an upper respiratory tract infection or infectious diarrhea, which triggers the deposition of immunoglobulin A (IgA) in the mesangial region of the glomeruli. This leads to inflammation and subsequent kidney damage characterized by hematuria and proteinuria.

Following infections, the immune response can alter the normal filtration function of the glomeruli, making IgA nephropathy a particularly relevant condition in this context. Its association with infections demonstrates the interplay between previous infectious events and the immune-mediated damage to kidney structures, making it a classic example in the discussion of post-infectious glomerulonephritis.

Other options relate to conditions that are either primary glomerular diseases or chronic conditions not directly stemming from an infection. Goodpasture's disease, for instance, is an autoimmune disorder that attacks the lungs and kidneys simultaneously. Hypertensive nephrosclerosis is a result of chronic hypertension, while membranoproliferative glomerulonephritis can arise from various causes but is often associated with infections like hepatitis, typically not classified as post-infectious
