[S. pneumoniae sternoclavicular arthritis in a patient with HIV infection].

HIV infection is a predisposing factor for pneumococcic infection. While pneumonia is the most frequent location, other locations (articular, meningeal, endocardiac, etc) have been less frequently described. Among the articular infections described in patients with HIV infection, the sternoclavicular affection is extremely rare and it usually develops in association with parenterally drug addiction, being Staphylococcus aureus and Pseudomonas aeruginosa the most frequently germs involved. We describe the first case of sternoclavicular arthritis by Streptococcus pneumoniae in a patient with HIV infection. In our case, the chronic hepatopathy associated to alcohol consumption is a predisposing factor related to the pneumococcic infection. Our case suggests the need to formally investigate the HIV infection in young patients with invasive pneumococcic infection.
