Pathology COPY Flashcards
nephrotic syndromes
- minimal change disease
- FSGS
- membranous nephropathy
- diabetic nephropathy
- amyloidosis
nephritic syndromes
-post-strep
glomerulonephritis
-berger’s (IgA) nephropathy
-diffuse proliferative glomerularnephritis
-crescentic GN (RPGN)
-Alport syndrome
-Membranoproliferative glomerulonephritis (MPGN)
nephrotic w/ foot process effacement
minimal change disease
FSGS
immune complex deposition
membranous nephropathy
membranoproliferative glomerulonephritis
mesangium deposition
diabetic nephropathy
amyloidosis
SLE related nephrotic syndrome
membranous nephropathy
SLE related nephritic syndrome
diffuse proliferative glomerulonephritis
*MOST COMMON SLE SYNDROME
thin/split BM
eye/ear disturbances
ALPORT SYNDROME
type IV collagen defect, nephritis
selective proteinuria
minimal change disease
loss of albumin due to heparin sulfate loss
exquisite sensitivity to steroids
minimal change disease
minimal change sx but no response to steroids
FSGS
HIV, sickle cell, heroin
FSGS
- thick BM
- subEPITHELIAL IC deposits (spike and dome)
- absence of hypercellularity
- (good prog in child, bad prog in adults
membranous nephropathy
anti-phospholipase A2 receptor Abs
membranous nephropathy
FSGS response to steroids
POOR, prog to chronic renal failure
membranous nephropathy response to steroids
POOR, prog to chronic renal failure
- recurrent hematuria
- thick BM, focal sclerosis (mesangial)
- nodular sclerosis (KIMMELSTIEL-WILSON BODIES)
- preferential hyaline arteriosclerosis in EFF a.
diabetic nephropathy
diabetic nephropathy MOA
hyperglycemia –> nonenzymatic glycation of tissue proteins –> mesangial expansion
GBM thickening/inc perm
hyperfiltration (glomerular HTN and inc GFR) –> glomerular hypertrophy and scarring
most comm cause ESRD in US
diabetic nephropathy
deposits in mesangium (B-pleated sheets)
- congo red –> apple-green birefringence
amyloidosis
SLE
solid tumors
Hepatitis (B/C)
nephrotic syndrome
membranous nephropathy
nephrOtic sx
- proteinuria (>3.5 g/dl) –> FROTHY urine
- hypOalbuminemia
- hyperlipidiemia (fatty casts/oval bods)
- hypercoaguability (AIII loss)
- dec plasma oncotic P so fluid leaks into tissues –> dec ECV/GFR, inc RAAS –> EDEMA (LE, peri-orbital)
- infections (loss of Ig)
tx of which nephritic syndrome is usu supportive bc IC dissipate out
post-strep glomerulonephritis
M protein virulence fx
peripheral/periorbital edema
HTN
cola urine
post-strep glomerulonephritis
2-3 weeks post infection
post-strep glomerulonephritis
subEPITHELIAL humps ("lumpy-bumpy"), deposition capillary loops w/ neutrophils
post-strep glomerulonephritis
dec complement levels (C3) due to infection
post-strep glomerulonephritis
type II membranoproliferazive glomerulonephritis
nephrITIC syndrome
- INFLAMM process damaging ENTIRE glomeruli
- damaged filtration barrier –> dec GFR –> inc BUN/Cr
- oliguria
- inc hydrostatic P –> HTN, edema
- filtration barrier to RBCs/protein lost (HEMATURIA)
- ->salt retention (periorbital edema +HTN)
- EM: hypercellular (neutrophils)
- UA: RBC casts (glomerular bleeding), dysmorphic RBCs
all nephritic syndrome have sub_____ deposition, except _______, which has sub_____ deposition.
all nephritic syndrome have subENDOTHELIAL deposition, except POST-STREP GN, which has subEPITHELIAL deposition.
