Study Notes
Immunofluorescence Findings in Rapidly Progressive Glomerulonephritis
-
Linear Pattern: Associated with Goodpasture syndrome. Antibodies target the basement membrane, often causing hematuria and hemoptysis, particularly in young to middle-aged males.
-
Granular Pattern: Most commonly linked to PSGN (post-streptococcal glomerulonephritis) or diffuse proliferative glomerulonephritis. Immune complex deposition is the primary feature, usually sub-endothelial. It is a frequent type of kidney disease seen in systemic lupus erythematosus (SLE).
-
Negative Immunofluorescence (Pauci-immune): Linked to conditions like Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome. These conditions are characterized by granulomatous inflammation, often with eosinophilia and asthma (in Churg-Strauss). Different types of antineutrophil cytoplasmic antibodies (ANCA) are associated: c-ANCA for Wegener's, and p-ANCA for microscopic polyangiitis and Churg-Strauss.
