Glomerulonephritis

Acute or chronic nephritis characterized by immune-mediated inflammation of glomerular capillary loops, leading to hematuria, proteinuria, edema, and possible progressive renal failure. Possible causes are post-infectious (streptococcus, HIV, hepatitis B, hepatitis C, endocarditis), autoimmune (SLE, anti-GBM Goodpasture's syndrome, vasculitis), hypertension, diabetes, genetic (Alport syndrome), and medications (NSAIDs, chemotherapy).
