Estimating disease burden of maternal syphilis and associated adverse pregnancy outcomes in India, Nigeria, and Zambia in 2012.

OBJECTIVE: To estimate maternal syphilis and its associated adverse pregnancy outcomes in India, Nigeria, and Zambia. METHODS: An online estimation tool was used to generate point estimates and uncertainty ranges of maternal syphilis and adverse pregnancy outcomes due to mother-to-child transmission (MTCT). The most recent data (2010-2012) on antenatal care coverage, syphilis seroprevalence, and syphilis screening and treatment coverage at the subnational level in India, Nigeria, and Zambia were used to estimate disease burden for 2012. Sensitivity analysis was conducted for three screening and treatment scenarios (current coverages, current coverages minus 20%, and ideal coverages consistent with WHO targets for eliminating MTCT of syphilis). RESULTS: A total of 103 960, 74 798, and 9072 pregnant women with probable active syphilis were estimated to occur in India, Nigeria, and Zambia, resulting in 53 187, 37 045, and 2973 adverse outcomes, respectively; approximately 1.6%, 4.8%, and 37.0% of these were averted under the current service coverages in India, Nigeria, and Zambia. The disease burden varied significantly in its subnational distribution within India and Nigeria, but was distributed evenly across Zambia. CONCLUSIONS: The obtained results suggest an ongoing, unaverted high burden of maternal syphilis and associated adverse outcomes in India, Nigeria, and Zambia. Screening and treatment for syphilis must be scaled-up significantly in these countries to achieve elimination of MTCT of syphilis.

Towards elimination of parent-to-child transmission of syphilis in India: a rapid situation review to inform national strategy.

In February 2015, India's National AIDS Control Organisation, Ministry of Health and Family Welfare, launched a national strategy towards elimination of parent-to-child transmission (E-PTCT) of syphilis, with a goal to reduce the incidence of congenital syphilis to 0.3 cases per 1000 live births by 2017. As part of the development of the national strategy, a rapid situation analysis was undertaken to ascertain the current practices, challenges and barriers for E-PTCT of syphilis in India. The analysis was conducted during February and March 2014 in five states selected from five different regions of India. Key informant interviews were conducted with key stakeholders at facility, state and district level. Content analysis was used to identify the themes. Key barriers identified for E-PTCT of syphilis were: low priority for antenatal syphilis testing among providers, limited access to testing, untrained human resources, shortage of test kits and benzathine penicillin, nonadherence to the national protocol for syphilis testing, and poor recording and reporting of antenatal syphilis data. The analysis also identified opportunities for functional integration of E-PTCT within existing maternal and child health programmes. Health-care providers and programme managers expressed a need for training in the programme for E-PTCT of syphilis. The situation analysis identified that, for successful implementation of E-PTCT of syphilis, it is essential that state and district programme managers adopt this initiative; coordinate the programme; plan for an adequate budget in their programme implementation plan; ensure an uninterrupted supply of standardized diagnostics kits and drugs at all levels of health care; and adhere to E-PTCT guidelines when implementing the programme.
