Anaphylactic shock caused by haemocoagulase injection in China.

ABSTRACT: Haemocoagulase injection is a mixture of purified enzymes isolated from the venom of Bothrops atrox, which is used for the prevention and treatment of haemorrhage. It is a relatively safe pharmacological agent that does not require a skin test prior to administration. However, following a literature search, 14 reported cases of anaphylactic shock caused by haemocoagulase injection were identified, including one lethal case in China. Using SDS-PAGE and protein identification, four primary components in haemocoagulase injection were characterized, including one metalloproteinase, which may be a thromboplastin-like enzyme, and two serine proteinases, which may be thrombin-like enzymes. Administering concentrated haemocoagulase injections failed to provoke a positive skin reaction in al
