Purulent pericarditis due to co-infection with Streptococcus pneumoniae and Mycobacterium tuberculosis in a patient with features of advanced HIV infection

Abstract

Background: Both Mycobacterium tuberculosis and Streptococcus pneumoniae are common pathogens in patients with HIV infection. Case Presentation: We present an unusual case of purulent pericarditis resulting in cardiac tamponade due to infection with both organisms. We highlight the re-emergence of pneumococcal pericarditis in the HIV era and describe the pitfalls and challenges in the diagnosis of this condition. Conclusion: Clinicians working in HIV endemic areas need to consider dual infection with these organisms in patients who respond inadequately to either antibiotics or anti-tuberculous therapy alone. © 2007 Louw and Tikly; licensee BioMed Central Ltd.
