Abstract:
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.
