Not a cause for edema in nephritic syndrome:
Ref: Harrison's Principles of internal Medicine. /8th edition, Pages 2340-2345 and Differential Diagnosis in Internal Medicine: From Symptom to Diagnosis, Edited by Walter Siegenthaler, Page 868Explanation:MECHANISM OF EDEMA IN ACUTE NEPHRITIC SYNDROMEEdema develops due to reduced oncotic pressure in the plasma.Fluid from the vascular compartment permeates into the interstitium.The resulting reduction of the intravascular volume stimulates the Renin-Angiotensin- aldosterone system, as well as the sympathetic nervous system, and leads to the release of anti-diuretic hormone (ADID.This results in increased salt and water retention by the kidney, which further promotes the development of edema.Increased peritoneal fluid production --*High hydrostatic pressure. Altered vascular permeabilily.
High hydrostatic pressure of plasma
Increased vascular permeability
Lymphatic obstruction
Decreased oncotic pressure of plasma
