Abstract
Disseminated intravascular coagulation (DIC) is a common and morbid complication of streptococcal toxic shock syndrome (STSS). Because DIC with STSS progresses rapidly, prompt and proper care is critical. The present report describes the case of a 10-year-old boy who survived STSS with DIC without sequelae after treatment with combination anticoagulant therapy of recombinant human soluble thrombomodulin (rhTM) and danaparoid. RhTM and antithrombin-III were administered on day 1. RhTM administration was continued. Despite this, on day 2, his general condition remained poor, his fever persisted and his DIC score increased from an initial 5 points upon admission to 9 points. Therefore, danaparoid was additionally administered from day 2 onwards. The patient recovered without serious complications. Combination anticoagulant therapy of rhTM and danaparoid for DIC in a child with STSS was effective and safe. Therefore, this combination therapy could be used as an option for managing high-risk, rapidly progressing disease states, which predispose to morbid sequelae and death, such as DIC with STSS. RhTM and danaparoid therapy may reduce the risk of serious complications, such as organ failure, and improve the prognosis not only in STSS but also in other conditions with infection and DIC concurrence, such as sepsis.
