Study Notes
Glomerular Diseases
- Glomerulopathy is a broad term that includes all glomerular diseases, which can be primary or secondary (part of a systemic disease).
Classification of Glomerulopathies
- Glomerulonephritis: conditions involving inflammation of the glomerulus, which can be acute or chronic.
- Characterized by asymptomatic hematuria, nephritic syndrome, and rapidly progressive glomerulonephritis (RPGN).
- Nephrotic glomerulopathy: conditions generally due to glomerular epithelial cell injury.
- Characterized by asymptomatic proteinuria and nephrotic syndrome.
Chronic Kidney Disease
- Defined as the progressive loss of renal function, which can be caused by glomerular, tubular, or interstitial disease.
- The final common pathway is usually glomerulosclerosis, characterized by segmental or global collapse with closure of the capillary lumens, making it impossible to filter plasma.
Types of Glomerular Lesions
- Focal: involves < 50% of glomeruli on light microscopy.
- Diffuse: involves > 50% of glomeruli on light microscopy.
- Segmental: involves only part of the glomerular tuft.
- Global: involves the entire glomerular tuft.
- Proliferative: characterized by an increased number of cells in the glomerulus, usually inflammatory cells.
- Membranous: characterized by thickening of the glomerular basement membrane.
- Crescent: characterized by accumulation of cells and proliferating parietal epithelial cells within Bowman's space, associated with severe disease.
- Membranoproliferative: characterized by a thickened glomerular basement membrane and proliferation.
