Abstract | BACKGROUND: METHODS: This was a nested retrospective study of HIV-infected patients enrolled in the Johns Hopkins HIV Clinical Cohort. BFP RPR was defined as a reactive RPR and a nonreactive fluorescent treponemal antibody-absorption (FTA-ABS) test. Patients with BFP tests were compared to 2 control groups: HIV-infected patients (1) with active syphilis (reactive RPR and FTA-ABS) and (2) without current syphilis (nonreactive RPR). A persistent BFP test was defined by having at least 2 visits with consistent BFP at all visits. RESULTS: Of 711 patients with HIV, 96 (13.5%) had BFP tests and 342 (48.1%) had syphilis. Twenty-two of 96 (23%) had persistent BFP tests. cART use was associated with decreased odds of BFP tests compared to having syphilis (adjusted odds ratio [AOR], 0.31; 95% CI, .15-.63) and those with nonreactive RPR (AOR, 0.42; 95% CI, .22-.81). cART use was also associated with decreased odds of BFP persistence (AOR, 0.07; 95% CI, .01-.33). Neither CD4 count nor HIV RNA was significantly associated with BFP test results. Lower RPR titers, younger age, and injection drug use were associated with increased odds of BFP. CONCLUSIONS: The use of cART appears to decrease the odds of BFP RPR tests. This finding suggests that nontreponemal titer fluctuations in persons with HIV may reflect the influence of factors unrelated to syphilis disease activity.
