A Case of Overwhelming Postsplenectomy Infection Caused by Streptococcus pneumoniae with Fulminant Purpura.

Severe infection in patients who have lost splenic function is called overwhelming postsplenectomy infection (OPSI). Untimely treatment of patients with OPSI results in critical conditions with mortality rates as high as 50 %-70 %. For patients who undergo a splenectomy, vaccination is recommended for the prevention of OPSI. However, in Japan, the vaccination utilization rates are low. Herein, we report a case of OPSI caused by Streptococcus pneumoniae with a fulminant purpura resulting in multi-organ failure, which could be reversed by intensive care.
