Audit of the use of benzathine penicillin, post-treatment syphilis serology and partner notification of patients with early infectious syphilis.

Recent increases in the incidence of early infectious syphilis have been particularly noted in men who have sex with men (MSM). Case-notes of 40 consecutive patients with infectious syphilis and follow-up data for one year were audited. Of the 40 patients, six were HIV co-infected. In all, 31 men received benzathine penicillin as first line while the remaining had other treatments. About 17 (42.5%) failed to attend for any post-treatment serological tests. Of the remainder, 17 (42.5%) attended for the first appointment and only 13 (32.5%) attended for the full one year follow-up. In all, 40 men in the study had 362 sexual contacts of which only 44 (12.2%) elected to be screened. This study illustrates the successful use of benzathine penicillin as first-line treatment, lack of patient compliance with post-treatment serological follow-up and difficulty with partner notification.
