[Epidemiological and evolutionary profile of tuberculosis under the influence og HIV]

Abstract

Introduction: We conducted this study to understand the impact of HIV infection on the epidemiology of tuberculosis (TB) in an outpatient care center.

Patients and methods: This is a retrospective and comparative study between subjects infected or not infected with HIV, using TB case notification data registered from October 2017 to September 2019 in the intermediate care facility (CDT) of the University Hospital of Libreville. Comparisons were made by bivariate analysis; proportions were compared using the Chi² or the Fisher Exact test. Variables of significant interest were included in a binary logistic regression model for multivariate analysis.

Results: Prevalence of HIV infection was 30.4%. Average age was 35.2 years with extremes at 15 and 83 years. In the results of the multivariate analysis, female patients were more frequently infected with HIV (p=0.002; OR=1.960, 95% CI [1.275 - 3.015]) and HIV infection was associated with a reduction in the proportion of PTB (+) (p=0.001; OR=0.483, 95% CI [0.311 - 0.752]). HIV infection was also associated with an increased proportion of new cases (P=0.007; OR=2.987, 95% CI [1.353 - 6.597]), EPT (p<0.001; OR=1.084, 95% CI [1.054 - 1.131] and an unfavorable therapeutic outcome (p=0.016; OR=2.744, 95% CI [1.208 - 6.233]).

Conclusion: TB/HIV co-infection remains high. It continues to negatively impact outpatient management of TB.
