Severe acute renal failure induced by the venom of Lonomia caterpillars.

A case of a patient developing anuric acute renal failure and a hemorrhagic syndrome resembling disseminated intravascular coagulation after contact with Lonomia caterpillars is reported. Renal histology showed only mild changes consistent with renal ischemia, although the patient never was hypotensive. The mechanisms of renal injury were obscure and might be related to transient glomerular ischemia due to microcirculation fibrin deposition or to direct venom nephrotoxicity.
