Glomerular Diseases Flashcards
causes of membranous nephropathy
primary: Ab to PLP A2 receptor (IgG)
secondary: drugs (NSAIDS, penicillamine, gold), infection (Hep, syphilis), SLE, tumours
subENDOthelial humps (2)
- diffuse PROLIFERATIVE
- membranoPROLIFERATIVE GN
ENDO = PROLIFERATIVE
nephrotic diseases
- diabetic nephropathy
- FSGS
- minimal change
- membranous nephropathy
- amyloidosis
nephrotic syndrome
- proteinuria!!
- low albumin
- edema
- low antithrombin
- risk of infection
- high lipids (liver makes them to increase oncotic pressure)
- frothy urine
efface peodocytes
minimal change
FSGS
types of RPGN
1: anti-GBM (linear): Goodpasture
2: immune complex (lumpy bumpy)
3: pauci-immune (NO Ig or complement) - with C-ANCA or p-ANCA
spike and dome
membranous nephropathy (subepithelial)
GRANULAR immune complex (3)
- membranous nephropathy
- post-strep GN
- diffuse proliferative (SLE)
p-ANCA
RPGN + microscopic polyangiitis
most common nephrotic syndrome in AA and Hispanics
FSGS
subEPIthelial humps (2)
- membranous nephropathy
- post-strep GN
both nephritis + nephrotic
- diffuse PROLIFERATIVE GN (SLE)
- membranoPROLIFERATIVE GN
IgG/IgM immune complexes (LOW complement levels) (4)
RPGN
post-strep GN
diffuse proliferative GN (SLE)
MPGN
nephritic syndrome
- light proteinuria
- hematuria
- RBC casts
- azotemia (BUN, Cr increased)
- oliguria
wire loops
diffuse proliferative (SLE)
deposit fibrin
Goodpasture (RPGN crescent)
