title: Congenital syphilis in a Nairobi maternity hospital.
abstract: OBJECTIVE
  To assess adverse pregnancy outcome associated with maternal syphilis and congenital syphilis rate based on FTA-ABS-19s-IgM.
  
  
  METHODS
  Descriptive cross-sectional study.
  
  
  METHODS
  Pumwani Maternity Hospital (PMH), the largest maternity unit in Nairobi, Kenya.
  
  
  METHODS
  Rapid Plasma Reagin reactive women and their live born infants.
  
  
  METHODS
  Syphilis serology in pregnant women, FTA-ABS-19s-IgM in cord blood and pregnancy outcome.
  
  
  RESULTS
  Three hundred and seventy seven out of 12,414 women (3%) were RPR+. 4.0% of RPR+ and 1.4% of RPR- women delivered a stillbirth (OR 3.0, p<0.001). 19% of RPR+ and 10% of RPR- had low birth weight deliveries (OR 2.1, p<0.001). Mothers untreated for syphilis during pregnancy had significantly more preterm births (18.5% vs 9.2%, OR 2.3, p=0.026), and more stillbirths (5.4% vs 1.0%, OR 6.3, p=0.044). Of the 200 randomly selected cord bloods of RPR+ women, 142 (72%) were TPHA+. Nine (6.3%) of the 142 TPHA+ cords were FTA-ABS-19s-IgM+.
  
  
  CONCLUSIONS
  Stillbirth and low birth weight rates were high in RPR+ untreated pregnant women and treatment significantly improved pregnancy outcome. Based on very stringent laboratory criteria (FTA-ABS-19s-IgM), 6.3% of live born infants with TPHA+ cord blood were considered syphilis infected.
