Pericarditis purulenta con taponamiento cardiaco por asociación de Streptococcus agalactiae y Salmonella enterica no typhi. / [Purulent pericarditis with pericardial tamponade caused by Streptococcus agalactiae and Salmonella enterica no typhi]

ABSTRACT

Purulent pericarditis (PP) is an uncommon condition with high mortality. In the preantibiotic period, Staphyloccocus aureus and Streptococcus pneumoniae were the most common etiologic agents. We describe the case of a 75-year old man with septic shock, PP and cardiac tamponade caused by Streptococcus agalactiae and Salmonella enterica no-typhi. To our knowledge this association of pathogenic organisms has not been previously reported in the literature. The pathogenesis is here reviewed, and in our patient presumably, purulent pericarditis occurred via hematogeneus spread undergoing upper gastrointestinal endoscopy. The patients course was complicated and he died on 34th hospital day. After this case report it is considered that differential etiologic diagnosis of PP should include these agents, especially in immunodepressed patients with predisposing factors.
