The cause of renal failure in septicaemic shock is



A Acute tubular necrosis
B Acute cortical necrosis

C Glomerulonephritis
D Focal sclerosis

Ans. A

Acute tubular necrosis

Septic shock (Bacteremic) is a state of shock associated with bacteria or bacterial products in the blood stream

1. Because of endotoxin affinity for kidney and lungs most of these patients die due to lung complications (shock-lung syndrome) or renal failure (Acute tubular necrosis)

2. Bilateral necrosis of the renal cortex is uncommon, it complicates between 15 and 30% of all cases of ARF associated with obstetrical causes

a. Most of the reported cases have followed such complications as placental abruption, preeclampsia or endotoxin induced shock, Histologically the lesion appears result from thrombosis of segment of the renal vascular system.

b. The lesion may be focal, patchy, confluent or gross, clinically renal cortical necrosis follows the course of ARF with oliguria or anuria, uremia, and generally death within 2 to 3 weeks.

c. Unless dialysis is initiated, differentiation from acute tubular necrosis during the early phase is not possible

3. Renal complication due to septic shock

Most renal failure is due to acute tubular necrosis induced by hypotension or capillary injury, although some patients also have glomerulonephritis, renal cortical necrosis or interstitial nephritis.
