Abstract
Background. Syphilis is a sexually transmitted infection that is most frequently found in lower socio-economic groups globally and is associated with significant maternal and fetal complications. In South Africa (SA), the last two to three decades have seen a rise in the number of people in the low and middle economic social groups seeking private specialist healthcare services.Objective. To evaluate the prevalence rates of maternal and congenital syphilis in a private specialist healthcare setting.
Methods. The laboratory case records of women who had antenatal maternal syphilis (MS) screening using the automated chemiluminescence immunoassay (Architect Syphilis TP) in a private laboratory facility in Durban were reviewed.Results. A total of 9 740 individual maternal serum samples were analysed and 256 were Architect Syphilis TP positive, resulting in a MS prevalence rate of 2.7%. Of the less than three-quarters of exposed neonates tested (71.1%; n=182/256), 38.5% (n=70/182) were Architect syphilis TP positive. Less than a tenth of exposed neonates (2.43%; n=6) had only rapid plasma reagin (RPR) titers test whereas 26.6% (n=68/256) did not have a syphilis screen test. Based on the 182 exposed neonates tested, the congenital syphilis (CS) prevalence from the laboratory records was 7.7%. The highest rate of MS was in the ≥35 years age group.
Conclusion. The prevalence of MS in the private specialist healthcare sector in SA is relatively high and warrants continued maternal antenatal screening during early pregnancy across all socio-economic groups. The high rate of MS in the age group over 35 years warrants further investigations and explanation.
