Glomerular Disease Flashcards
equivalent of clinical presentation of RPGN
crescentic glomerulonephritis
producing 1-2g/hr of proteinuria, hematuria with rbc casts, pyuria, hypertension, fluid retention, increased serum creatinine over many weeks
acute nephritic syndrome
onset of heavy proteinuria >3g/24hr, hypertension, hypercholesterolemia, hypoalbuminemia, edema/ anasarca, microsopic hematuria
nephrotic syndrome
serum creatinine rises quickly over a span of days
Rapidly Progressive Glomerulonephritis (RPGN)
subepithelial deposits on renal biopsy called “humps” is seen in
poststreptococcal glomerulonephritis
grossly, the kidneys have subcapsular hemorrhages with a “flea-bitten” appearance
subacute bacterial endocarditis
anit-GBM with lung hemorrhage and glomerulonephritis
goodpasture’s syndrome
renal biopsy of goodpasture’s syndrome
focal or segmental necrosis
most common form of glomerulonephritis
IgA nephropathy
common presentation of IgA nephropahty
macroscopic hematuria (followed by URT infection) proteinuria or asymptomatic microscopic hematuria
similar with IgA nephropathy
henoch-schönlein purpura
antibody more common in granulomatosis with polyangiitis
anti-proteinase 3 (PR3)
antibody more common in microscopic polyangiitis or churg-strauss
anti-myeloperoxidase (MPO)
more common in patients exposed to silica dust or with a1-antitrypsin deficiency
granulomatosis with polyangiitis
peripheral eosinophilia, asthma, cutaneous purpura, mononeuritis and allergic rhinitis
churg-stauss syndrome
thickening of the GBM
membranoproliferative glomerulonephritis (MPGN)
MPGN type commonly associated with persistent hepatitis C
type I
MPGN types II and III are driven by what complement pathway
alternative complement pathway
the most proliferative MPGN type that shows mesangial interposition between the capillary basement membrane and endothelial cells producing a double contour called
tram tracking
expansion of mesangium sometimes associated with mesangial hypercellularity
mesangioproliferative glomerulonephritis
heavy proteinuria, minimal hematuria, hypoalbuminemia, hypercholesterolemia, edema and hypertension
nephrotic syndrome
causes 70-90% of nephrotic syndrome in childhood but only 10-15% in adults
minimal change disease
in electron microscopy it shows effacement of the foot processes with weakening of slit-pore membranes
minimal change disease
pattern of segmental glomerular scars
focal segmantal glomerulosclerosis
