Low male partner attendance after syphilis screening in pregnant women leads to worse birth outcomes: the Syphilis Treatment of Partners (STOP) randomised control trial.

Abstract

Pregnant women with a positive point-of-care treponemal test at three antenatal clinics (ANCs) in Kampala, Uganda, were randomised 1:1:1 to receive either notification slips (NS; standard of care), NS and a text messages (SMS) or NS and telephone calls. The primary outcome was the proportion of partners who attended the ANC and were treated for syphilis. Between 2015 and 2016, 17130 pregnant women were screened; 601 (3.5%) had a positive treponemal result, and 442 were enrolled in the study. Only 81 of 442 partners (18.3%; 23/152 (15.1%), 31/144 (21.5%) and 27/146 (18.5%) in the NS only, NS + SMS and NS + telephone call groups respectively) attended an ANC for follow-up; there were no significant differences between the groups. Twelve per cent of women attended the ANC with their male partner, and this proportion increased over time. Partner non-treatment was independently associated with adverse birth outcomes (odds ratio 2.75; 95% confidence interval 2.36-3.21; P < 0.001). Only 18.3% of partners of pregnant women who tested positive for syphilis received treatment. Female partners of non-attendant men had worse birth outcomes. Encouraging men to accompany women to the ANC and testing both may address the urgent need to treat partners of pregnant women in sub-Saharan Africa to reduce poor fetal outcomes.
