Influence of the ABO system on the hemolytic activity of medically relevant Loxosceles venoms in Brazil

Abstract

Envenomation by Loxosceles spiders is an important public health issue, frequently associated with hemolysis. Although the ABO blood group system influences various diseases, its role in loxoscelism is poorly understood. This study evaluated the effect of ABO types on hemolysis induced by L. intermedia, L. gaucho, and L. laeta venoms, with and without complement. Blood type B erythrocytes showed reduced susceptibility to direct hemolysis, suggesting a potential protective effect and offering new insights for improving loxoscelism management.
