GN, nephrotic syndrome, PKD Flashcards
what is glomerulonephritis?
damage of the renal glomeruli by deposition of inflammatory proteins in the glomerular membranes as the result of an immunologic response.
60% of glomerulonephritis occurs in who? prognosis?
kids 2-12. prognosis only good in kids, worse in adults
Sx: edema in face/eyes in morning and edema of feet/ankles in the evening
glomerulonephritits symptoms
what is a common cause of GN
post streptococcal infection
what is the major lab to get in GN
antistreptolysin O titer
UA reveals oval fat body
think nephrotic syndrome (it is a renal tubular cell that has reabsorbed some of the excess lipids in urine)
Over 3.5 gm proteinuria/24 hrs
Nephrotic syndrome
Hypoalbumnemia, azotemina, hyperlipemia, C3 levels nml or low
Nephrotic syndrome
Maltese crosses and oval fat bodies
Nephrotic syndrome
Common cause of nephritic syndrome
Post strep throat inf
main difference in nephritic vs neprotic syndrome
nephritic is proliferation; nephrotic is membraneuous
eosinophils in urine
malignant HBP
SLE
Nephritic and nephrotic syndrome
what is the most common form of polycystic kidney disease(PKD)
autosomal dominant PKD, it is always bilateral. occurs in the 30s
common sx of autosomal dominant PKD
back and flank pain and headaches
tx for autosomal dominant PKD
supportive. antibx
UA shows proteinuria, hematuria, pyuria, and bacteriuria
PKD
glomerulonephritits symptoms
Sx: edema in face/eyes in morning and edema of feet/ankles in the evening
describe UA findings in GN
- hematuria (>3RBC/high power field, they will be misshapened due to passage through glomerulus(acanthocytes).
they are normal shaped when bleeding from bladder or urethra
-RBC casts, proteinuria(1-2 g/24h)
hematuria, RBC casts, proteinuria
GN
serum complement (C3) in GN
decreased
how to dx GN
antistreptolysin O titer
UA
C3
renal bx- determine exact dx or severity( electron microscopy and immunofluorescence)
tx for GN
- steroids and immunosuppressive drugs for inflammation. (none in PSGN)
- diet: decrease salt and fluid intake
- dialysis if azotemia
- ACE inh in chronic
treat hyperkalemia, pulm edema, peripheral edema, acidosis, HTN
benign hematuria
henoch schonlein purpura
mild post infectious GN
IgA nepropathy
hereditary nephritis
causes of focal GN in kids
tea or coca cola colored urine
hematuria, think GN or nephritic syndrome
bergers disease(Iga nephropathy)
endocarditis
lupus
infectious
strep
all causes of GN
main difference between nephrotic syndrome and nephritic syndrome
nephrotic has no inflammation
nephritic has inflammation of kidney
explain hyperlipidemia in nephritic syndrome
secondary to liver producing increased lipoproteins due to hypovolemia from loss of intravascular volume(edema)
post infectious GN
membranoproliferative GN
causes of diffuse GN in kids
IgA nepropathy
hereditary nephritis
SLE
causes of focal GN in adults
SLE
membranoproliferative GN
rapidly progressive GN
post infectious GN
vasculitis
causes of diffuse GN in adults
