Clostridium paraputrificum: An atypical and rare case of septic arthritis mimicking an acute sickle cell crisis

Clostridium paraputrificum is an extremely rare species and constitutes only 1% of all clostridium infections in literature. Septic arthritis from Clostridium paraputrificum is even less documented, and currently there is only one known case report. Specifically, patients with sickle cell disease have a well-documented and increased susceptibility to infections with Salmonella, Streptococcus pneumoniae, Hemophilius influenzae, and Enterobacter-klebsiella. Clostridium infection in sickle cell patients has been less studied and described. Here we present a case of septic arthritis from Clostridium paraputrificum in a sickle cell disease patient likely provoked by underlying avascular necrosis of the right shoulder.
