Septicaemia in patients with AIDS.

During a 5 year period at St Stephen's hospital, London, septicaemia was detected in 66 patients with the acquired immune deficiency syndrome (AIDS) and in 13 other patients with non-AIDS-associated HIV infections. The most frequent pathogens in patients with AIDS were Mycobacterium avium-intracellulare, Streptococcus pneumoniae, Pseudomonas aeruginosa, Cryptococcus neoformans and staphylococci. A series of HIV-associated septicaemias reported from other centres in different countries has shown great variation in the pattern of aetiological agents observed, which may partly reflect differences in the local socio-economic condition, ethnic backgrounds, other predisposing factors, and blood culture techniques. Salmonella species were a prominent cause of septicaemia in several reports. Most centres have also reported an increasing problem with septicaemias associated with intravenous lines in patients receiving antiviral or other parenteral drug therapy.
