Four of the 139 children with hemophilia followed up at our center have developed septic arthritis during the past 6 years (2.9% incidence). Two infections were caused by Streptococcus pneumoniae and one each by Staphylococcus aureus and Haemophilus influenzae type B. Common features at time of presentation included fever and a 2- to 7-day history of joint pain and swelling unresponsive to factor replacement infusions. Since three of the patients were human immunodeficiency virus seropositive, we propose that human immunodeficiency virus infection may be responsible for the disproportionately high number of cases of septic arthritis observed in our patient population.

Reports pertinent to bacterial arthritis in 1997 included two large, multi-year surveys of joint infection in patients from defined European health districts, noting trends including the declining incidence of gonococcal arthritis and an increasing number of prosthetic joint infections. Children with infected joints generally fare better than adults despite having proportionately more infections due to gram-negative organisms, of which Hemophilus influenzae comprises an ever smaller portion as the fastidious Kingella kingea is emerging. Joint infections remain an uncommon complication of immunodeficiency due to HIV, with responsible agents, affected sites, and clinical course also influenced by certain HIV comorbidities such as intravenous drug user and hemophilia. The rare immunodeficient patient with hypogammaglobulinemia retains a nearly unique susceptibility to joint infection with mycoplasmas, which can cause considerable morbidity if not promptly recognized and treated. Polymerase chain reaction can detect remnants of bacteria in the face of negative conventional cultures, but inoculation of synovial fluid into blood cultures bottles may be a more immediate and practical method to increase the yield in suspected septic arthritis.

Paediatric musculoskeletal infection remains an important cause of morbidity. Methicillin sensitive Staphylococcus aureus is still the most common organism although the incidence of methicillin resistant S. aureus in the community is rising. Osteomyelitis and septic arthritis due to Haemophilus influenzae is decreasing in incidence secondary to immunisation and in some units has been replaced by infections with the gram negative bacillus, Kingella kingae. Recent prospective studies indicate that uncomplicated osteomyelitis can be treated by three to four weeks of antibiotics. However, there is still a small group of children who will have overwhelming disseminated infection. These children require aggressive surgical and medical intervention. Two recent reports have identified an increased incidence of septic arthritis in children who have hemophilia and are HIV positive.
