title: Bacterial infections in HIV-infected patients.
abstract: Although the original opportunistic pathogens described in AIDS were protozoal and fungal organisms, bacterial infections are now recognized with increased prevalence and altered expression in patients with HIV infection. Especially since populations outside of North America and populations of i.v. drug abusers have been studied, bacterial infections have been shown to cause substantially increased morbidity and mortality both early and late in the course of HIV infection. Just as strategies have been developed for primary and secondary prophylaxis of classical HIV-related opportunistic infections, prevention of bacterial complications should be a high priority. Good hygiene and avoidance of unsterile needles in illicit drug use, tattooing, ear-piercing, or other cosmetic or ritual activities should be emphasized in patient education. Patients should be counseled to avoid uncooked or poorly cooked eggs and poultry and to avoid unpasteurized milk products. Pneumococcal vaccine is recommended for all HIV-seropositive patients and should be given as early as possible after recognition of HIV infection for maximal efficacy. Influenza vaccine is also recommended. It may have a role in preventing bacterial pneumonia secondary to influenza. Patient management should include regular dental care and nutritional evaluation. The use of intravenous or central catheters should be limited to essential therapies. When patients present with new febrile illness, a high index of suspicion for invasive bacterial disease is appropriate. The signs of serious bacterial infection in HIV-positive patients are subtle. Diagnostic evaluation should include cultures of blood and other relevant clinical specimens. Empiric antimicrobial therapy based on the clinical presentation may be life saving in patients with invasive bacterial disease complicating HIV infection.
