Hemorrhagic syndrome caused by Lonornia (Saturniidae) caterpillars in Casanare, Colombia: two cases

Abstract

Two cases of contact with Lonomia caterpillars were diagnosed in Colombia. Lonomia caterpillars cause hernorrhagic disorders characterized by an intense fibrinolytic activity and low levels of several coagulation factors. Both cases occurred in the Casanare Department and were referred to San Carlos Hospital in Bogota. Each case developed differently. The first died as a consequence of hemoptisis and secondary renal failure. and the second had symptoms of gum and vaginal bleeding but recovered aíter administration of anti-Lonomia serum. These are first cases of Lonomia contact in Colombia; initiation of syndrome recognition, research, and prevention programs are recornmended.
