Q

NEPHROTIC SYNDROME
What is the pathophysiology of nephrotic syndrome?

A
  1. Inflammation – from immune cells (Ab’s, Ig’s - IgG), complement proteins, HTN, atherosclerosis, medications/immunisations, infection
  2. Damage to podocytes – protein leakage (albumin, Ab’s)
  3. Increased liver activity – to increase albumin, - Consequential increase in cholesterol + coagulation factors
  4. Reduced oncotic pressure – oedema - Consequential blood volume decrease, RAAS stimulation, exacerbation
