Stopped: An error of the sample size calculation occurred. A previous calculation based on a previous trial by Cao et al estimated to assign 150 participants to each group. A corrected calculation showed that 43 participants for each group is sufficient.
In a prospective study investigating the prevalence of sexually transmitted infections (STIs) among at-risk people living with HIV (PLWH), the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae was 24.7% and 12.1%, respectively. Surprisingly, the study found high rates of C. trachomatis and/or N. gonorrhoeae co-infections in PLWH with recent hepatitis C virus (HCV) infection (50%), HBsAg positivity (44%), and early syphilis (36%). Considering the high rate of sexually transmitted co-infections, combination therapy of single-dose ceftriaxone plus 7-day doxycycline for early syphilis may provide convenience and benefit to treatment of N. gonorrhoeae and C. trachomatis co-infections at a single clinic encounter. In the present study, this study aim to compare the efficacy of ceftriaxone plus doxycycline versus benzathine penicillin G (BPG) plus doxycycline as the treatment for early syphilis among PLWH.
