Tamponamento Cardíaco Secundário a Pericardite por Staphylococcus Aureus Meticilino Resistente: Importância da Imunossupressão
2008
Since the advent of antibiotics, bacterial pericarditis has become relatively rare. Cardiac tamponade is a potentially lethal complication. especially when caused by methicillin-resistant Staphylococcus aureus (MRSA). Inthe intensive care setting other predisposing factors for purulent pericarditis, besides immunosuppressin, are the high incidence of nasal and skin colonization and invasive techniques such as indwelling catheters. We present two case reports of cardiac tamponade in young patients, with underlying immunosuppression of different etiologies (HIV infection and liver transplantation). In both, clinical evolution was complicited by severe sepsis, with MRSA being isolated in various biological products, followed by bacterial pericarditis and tamponade. The authors highlight the need for a high decree of suspicion for the diagnosis of bacterial pericarditis in immunosuppressed patients, an ever-growing population, as well as the importance of echocardiographic monitoring during clinical evolution.
