Study Notes
Glomerular Diseases and Chronic Glomerulonephritis Overview
- Glomerular diseases are characterized by proliferation of cells in glomeruli and leukocyte infiltration, leading to reduced GFR, oliguria, fluid retention, and azotemia
- Acute Postinfectious (Poststreptococcal) GN is a classic case in children occurring after recovery from group A streptococcal infection, characterized by increased cellularity of glomerular tufts and subepithelial deposits of immune complexes
- IgA Nephropathy (Berger Disease) affects children and young adults, presenting with episodes of gross hematuria after upper respiratory tract infections, and is one of the most common causes of recurrent hematuria
- Rapidly Progressive (Crescentic) GN is a clinical syndrome with rapid and progressive loss of renal function, characterized by crescents due to proliferation of parietal epithelial cells and infiltration of monocytes and macrophages
- Three types of RPGN: Pauci-Immune (Type III) Crescentic GN, Anti-Glomerular Basement Membrane Antibody (Type I) Crescentic GN, and Immune Complex-Mediated (Type II) Crescentic GN
- Chronic Glomerulonephritis is an important cause of end-stage kidney disease, presenting as chronic renal failure with advanced scarring of glomeruli, interstitial fibrosis, and hypertension-induced arterial changes
- Diseases Affecting Tubules and Interstitium include inflammatory involvement or ischemic/toxic tubular injury leading to acute tubular necrosis and acute renal failure
- Tubulointerstitial nephritis (TIN) primarily involves the interstitium and tubules, with bacterial infection causing pyelonephritis and nonbacterial cases termed interstitial nephritis
- Acute Pyelonephritis is a common suppurative inflammation of the kidney and renal pelvis caused by bacterial infection, often by enteric gram-negative rods
- Common causes of TIN include bacterial infection, overconsumption of certain medications like Tylenol or ibuprofen, and nonbacterial origins
- Pyelonephritis affects the pelvic region and is often caused by bacteria, leading to suppurative inflammation
- Glomerular diseases and chronic glomerulonephritis have distinct clinical and histologic features, and understanding these conditions is vital for accurate diagnosis and appropriate management.
