Clinical relevance of brown snake (Pseudonaja spp) factor V escaping hemostatic regulation (letter)

摘要

Despite the work by Bos et al. reported in Blood and by other researchers on the structure and function of the procoagulant molecules, the pathophysiology of venom-induced consumption coagulopathy (VICC) associated with human envenoming by these snakes remains unclear. Although it would appear that the presence of a factor Va–like toxin in brown snake (Pseudonaja spp) venom that is impervious to regulation by the hemostatic system provides a potent biologic weapon against prey and in human envenoming, clinical research does not fully support this.
