ABSTRACT

Background:

Data on Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) infections within HIV pre-exposure prophylaxis (PrEP) programs in low- and middle-income countries (LMICs) are limited. Our study reports the prevalence, anatomical distribution, and correlates of NG and CT infections within an HIV PrEP program in Hanoi, Vietnam.

Methods:

From January-December 2022, HIV PrEP program clients who were male at birth, ≥16 years old, reported ≥1 male sex partner in the prior 12 months, were enrolled. A questionnaire collected sociodemographics, sexual behaviors, and clinical data. CT/NG testing was performed on self-collected urine, rectal, and pharyngeal specimens. Multivariate logistic regression was used to identify factors associated with CT and NG infections.

Results:

There were 529 participants enrolled, the median age was 25.1 years. The overall prevalence of CT or NG was 28.9% (153/529). The prevalence of NG was 14.3% and highest for pharyngeal infections (11.7%), while for CT, the prevalence was 20.4% and highest for rectal infections (14.0%). Symptoms in the prior week were reported by 45.8% (70/153) of those with CT or NG infections. Condomless anal sex (aOR= 1.98; 95% CI 1.27, 3.08) and sexualized drug use in the prior 6 months (aOR= 1.68; 95% CI 1.07, 2.65) were associated with CT/NG infections.

Conclusions:

Our study found a high prevalence of NG and CT infections, including pharyngeal and rectal infections, within an HIV PrEP program in Hanoi, Vietnam. The findings underscore the need for further research on CT/NG prevention and the development of evidence-based guidelines for CT/NG screening in HIV PrEP programs in LMIC settings.
