Azithromycin, an effective treatment for early syphilis, works well in those with HIV

A single dose of an oral antibiotic provides treatment for early and latent syphilis that is equivalent to the currently recommended penicillin injection, according to a study reported in the September 22ndedition of the New England Journal of Medicine. The investigators found that a single oral dose consisting of 2g of azithromycin (Zithromax) achieved cure rates for syphilitic chancres comparable to penicillin G benzathine, and that individuals who were treated with azithromycin had cure rates at three, six, and nine months equivalent to those seen in patients treated with penicillin injections.

What’s more, over 50% of the study population were HIV-positive and azithromycin was found to be as effective a treatment for syphilis in these patients as injections with penicillin. However, the investigators note that a strain of azithromycin-resistant syphilis has been found in HIV-positive individuals in the United States and Ireland.

Many treatment guidelines recommend a single intramuscular injection with 2.4 million units (MU) of penicillin G benzathine for early syphilis. The main advantages of this treatment are low cost and a low risk of resistance. However, the injection can be painful, trained healthcare staff are required to administer them, many patients report an allergy to penicillin, and in low income settings, there is a risk that blood-borne organisms, including HIV, will be transmitted if injecting equipment is reused.
