Acute renal failure due to viperine snake bite as seen in tropical western India.

A wide spectrum of clinicopathological changes have been described in 50 cases of ARF following viperine snake bite studied prospectively over a 15-year period. Disseminated intravascular coagulation (DIC) was seen in 24/50 cases (Russel's viper bite in 62% and Ecchis carinatus bite in 42% of subjects). Histological examination of renal tissue obtained 1.5 days to 8 weeks after the bite revealed proliferative glomerular changes in 17 cases. These were characterized by ballooning of the capillaries, thickening and splitting of glomerular basement membrane (GMB), fibrin thrombi in the capillaries, and mesangial cell proliferation most prominently seen in Ecchis carinatus bites resulting in ARF.

Clinicopathological study of acute renal failure following viperine snake bite.

Fifty patients of acute renal failure following Viperine snake bite were studied. Oliguria (100%), local swelling (48%) and bleeding tendencies (42%) were the predominant clinical features encountered. Of the 25 patients in whom detailed coagulation studies were done, 24 patients had disseminated intravascular coagulation (DIC) and 1 had primary fibrinolysis. DIC was commoner with Russell's viper bite (62%) in comparison to Echis carinatus bites (40%). Renal histology obtained in 29 cases revealed tubular necrosis (35%), cortical necrosis (24%) tubular degeneration (17%) and glomerular changes (17%). Ballooning of glomerular capillaries (59%), splitting of glomerular basement membrane (40.7%), swelling of endothelial cells (29.6%), and focal proliferation of mesangial cells (17%) were the significant glomerular changes encountered. 20 (40%) patients succumbed, DIC (50%), irreversible shock (30%) and septicaemia (20%) being the immediate causes of death. Development of oliguria within 24 hours of snake bite and cortical necrosis were associated with higher mortality.

Acute renal failure--a complication of new multidrug regimen for treatment of leprosy.

A leprosy patient who developed acute renal failure on multidrug therapy is reported. The patient had initially received a once-weekly dose of rifampin and after he had stopped taking the drug for a time, was given rifampin on a once-monthly dose schedule. He recovered completely from his acute renal failure. Kidney biopsy showed interstitial nephritis with mononuclear and eosinophilic cellular infiltrates.
