[Spontaneous bacterial peritonitis with Streptococcus constellatus in an HIV positive patient]

Liver diseases are an important cause of high morbidity and mortality in HIV-infected patients, and liver cirrhosis is the commonest cause of ascites in this population. We describe the case of a 38-year-old HIV-positive male (CDC stage B3, CD4 cell count 199/mm3) with a history of hepatitis C-associated liver cirrhosis. Following pneumonia he developed spontaneous bacterial peritonitis due to Streptococcus constellatus. Clinically noticeable was the gradually worsening course with few symptoms, despite the initially high ascitic fluid leucocyte count of over 11,000/microliter, but a favourable response to betalactam antibiotics.
