Abstract
The worldwide resurgence of syphilis may have serious implications on neonatal morbidity. The aim of this study was to evaluate the seroprevalence of syphilis in men attending an infertility clinic. Blood samples from 782 males were screened using the titrated RPR and TPHA tests. If either of these tests was positive, FTA-ABs IgG was performed. The RPR was positive in 63 (8%) cases. In 24 (3%) patients the titer was 1:8 with positive TPHA and FTA-Abs IgG tests and these were regarded as current infections. Thirty-nine (4.9%) cases had RPR titers 1:8 with positive specific tests. These were probably patients either treated inadequately or in the early stage of primary syphilis. In addition, 92 (12%) patients were RPR negative but TPHA and FTA positive. This was evidence of previous exposure to syphilis. The overall seropositivity in this group was 20% (155 cases). Six hundred and twenty-seven (80%) tested negative with RPR and TPHA. Syphilis may still have a major impact on health in Southern Africa. Since syphilis is significantly associated with HIV seropositivity, efforts to prevent and control syphilis may also be important in limiting the spread of HIV.
