Abstract:
Introduction: Surveillance of antibiotic resistant bacteria provides important information to optimize care for people living with HIV (PLHIV). The objective of this work was to determine the prevalence of bacteremia in PLHIV and to describe the biochemical profile and resistance of bacteria to antibiotics commonly prescribed for the care of patients and followed in the cohort in the infectious disease departments (SMI) of the National Reference University Hospital (CHU-RN) of N'Djamena.
Material and methods: This was a descriptive, analytical and etiological diagnostic study carried out on isolates responsible for bacteremia in PLHIV, from 01/01/2020 to 03/31/2023. The isolation, the identification of the bacteria and the antibiogram were carried out by standard methods of clinical microbiology.
Results: The study included 111 PLHIV, 51 of who were positive on blood culture (54%). The average age of PLHIV was 45.5 years with the extremes ranging from 15 and 76 years. The age group most affected by bacteremia was that of 55 years and over. A significant difference was observed in terms of the predominance of women over men (P = 0.02). The most identified bacteria were Staphylococcus aureus (56.86%) and Escherichia coli (16.68%). The most determined resistance phenotypes were multi-resistant bacteria (BMR) and extended-spectrum beta-lactamases (ESBL) with the proportions of 29.41% and 23.52% respectively.
Conclusion: The results of this study raise the need for continuous monitoring of antibacterial resistance and to apply the recommendations for the proper use of antibiotics among PLHIV in Chad.
