Abstract

We identified and reviewed retrospectively all the cases of infection by Pseudomonas and related genera in patients with AIDS and AIDS-related complex (ARC) who were hospitalized at our Institution over a 36-month period. We recorded 48 episodes of infection in 34 of 355 patients with AIDS, and in two of 73 patients with ARC: 25 pneumonias (9 community-acquired and 16 of nosocomial origin). 20 urinary tract infections, two soft tissue infections and one sepsis. In 14 of 16 patients with nosocomial pneumonia but in only one of nine patients with community-acquired pneumonia did we find coexisting opportunistic lung diseases. The following micro-organisms were isolated: P. aeruginosa in 41 cases, P. fluorescens in three cases, Xanthomonas maltophilia (P. maltophilia) in two cases, P. putida in one case. Comamonas testosteronis (P. testosteronis) and Comamonas acidovorans (P. acidovorans) in one case. Amikacin and ceftazidime, alone or in combination, appear to be the optimal choice of therapy for severe Pseudomonas infections in HIV-infected patients, although in our study six of 47 isolates were resistant in vitro to amikacin, and nine of 31 isolates were resistant to ceftazidime.
