[Non-typhoid salmonellosis in HIV infection].

Non-typhoid Salmonella infections associated with HIV infection are 20 times more frequent than those observed in the general population. Drug addicts and homosexuals are equally infected. Concerning physiopathology, a deficit in gastric acid secretion has been blamed as an etiological factor, together with T-cell deficit, except for reduction in the number of CD4 cells. This type of infection usually presents as fever; diarrhea is noted in only 20% of the cases. Several viscera can be involved. The best treatment seems to be fluoroquinones administered during 3 weeks, and several months in case of relapse. Patients under AZT therapy are less often affected with salmonellosis due to the antibiotic activity of this anti-retrovirus agent.
