[Invasive extrapulmonary infections due to Streptococcus pneumoniae. Report of three fatal cases and review]

Abstract

Streptococcus pneumoniae is a most important patogen in respiratory and meningeal infections. It is also a relevant agent of septic arthritis, pericarditis, acute endocarditis and spontaneous peritonitis in cirrhotic patients with ascites. It is less well known as a cause of infections in many other sites, including abdominal organs and soft tissues, which may be very severe. In this report, we describe three fatal cases (phlegmonous gastritis, cellulitis and primary peritonitis without pre-existing ascites) due to Streptococcus pneumoniae. In the last years it has become clear that this agent can cause infections at almost any body level, which is worth remembering. We review the literature and discuss some clinical aspects of two rare infectious syndromes, like primary peritonitis without previous ascites and phlegmonous gastritis.
