CD4 and syphilis: Compared with patients receiving benzathine penicillin G, patients receiving azithromycin had a higher CD4 count; were more likely to be on combination antiretroviral therapy (81.8% vs. 56.3%; p<0.001) with good viral suppression (plasma HIV RNA load <50 copies/mL) when early syphilis was diagnosed, to have received a previous diagnosis of syphilis and to present with early syphilis, and they were less likely to have an RPR titre ≥32.
