Q

What is nephritic syndrome?

A

Nephritic syndrome is a syndrome comprising signs of nephritis, which is kidney disease involving inflammation.

It often occurs in glomerulonephritis, which is characterized by a thin glomerular basement membrane and small pores in the podocytes of the glomerulus, large enough to permit proteins and red blood cells to pass into the urine

Q

Tell me about digoxin

A

Its used for the treatment of chronic heart failure
Its an inotrope
it does NOT improve survival

It works by blocking the na/k pump causing a rise in iIC na which via na/ca exchange increases the IC conc of ca and hence contractility (inotrope).
It hence increases the AV delay and the HR is indirectly slowed.
