urologic problems: glomerulonephritis Flashcards
what is the glomerus
delicate network of arterioles within Bowman’s capsule
- there is high pressure into the afferent pathway all these capillaries pushing fluids/toxin/waste - higher pressure at efferent arteriole leaving capsules
what is glomerulonephritis
inflammation of the glomeruli
-can happen from infection or post infection
difference between primary and secondary glomerulonephritis
primary is isolated to the kidneys
secondary is caused by systemic disease
hypersensitivity Type 2 and 3 of glomerulonephritis
type 2: specific antibodies that attack glomerular basement membrane (GBM) these antibodies are called anti-GBM antibodies -> losing enough of these glomerular cells can lead to kidney failure
type 3: antibodies react with antigens and form immune complex –> deposited into GBM –> causes inflammation and destruction
what is acute glomerulonephritis
abrupt onset of glomerulonephritis
clinical manifestations of acute glomerulonephritis
H.A.R.P
Hematuria (blood in urine)
Azotemia (build up of waste)
Retention (of sodium and water –> edema, HTN)
Proteinuria
Patho of acute glomerulonephritis
there is a trigger –> immune complexes form –> complement activated –> release of mediators –> tissue injury –> hematuria, proteinuria, decreased GFR (glomerular filtration rate)
what is chronic glomerulonephritis
long term inflammation (more than a few weeks)
what is formed in chronic glomerulonephritis
scar tissue develops causing the kidneys to be unable to filter/produce urine effectively = less kidney function
clinical manifestations of chronic glomerulonephritis
hematuria, proteinuria, azotemia, retention –> will start to see signs of renal failure which will then possibly cause end of stage renal disease
what is nephrotic syndrome
glomerulus is too permeable to plasma proteins –> elimination of >3g of protein/day
etiology of nephrotic syndrome
diabetes
glomerulonephritis
patho of nephrotic syndrome
damage to glomerulus –> increased glomerular permeability –> proteinuria –> hypoalbuminemia
clinical manifestations of nephrotic syndrome
edema (third spacing)
hypertension
