BACKGROUND

Bloodstream infections are a growing problem and currently a threat to public health. Bacteremia accounts for 15% of all nosocomial infections. In patients with HIV, the degree of immunosuppression continues to be the most important risk factor.

OBJECTIVE

To describe the clinical microbiological and epidemiological characteristics of patients with HIV infection and bacteremia.

MATERIAL AND METHOD

A descriptive observational study with patients over 14 years of age with positive blood cultures from the internal medicine service of the Hospital Universitario de Santander, Colombia, between 2014 and 2016, with HIV infection and who met the CDC criteria for torrent infection.

RESULTS

We reviewed 450 records, 44 patients with confirmed diagnosis. 59% were men; the mean age was 42 years. The median of CD4+T lymphocytes count was 29 cells/mm3, 55.8% had no antiretroviral treatment because they were new diagnoses. The mortality rate was 31.8%. The PITT severity index was classified as mild at 68.1%. The most frequent group of bacteria was the Enterobacteriaceae including K. pneumoniae with 25%. The percentage of resistant germs (E. coli and K. pneumoniae BLEE, P. aeuruginosa MDR, A. baumanii MDR and S. aureus MR) was 26.9%.

CONCLUSIONS

The group of patients with HIV in our institution is superior to other series. One in four patients with HIV infection and bacteremia have resistant microorganism.
