title: [Syphilis in pregnancy women].
abstract: OBJECTIVE
  To investigate obstetric treatment and pregnancy outcomes of syphilis infection during pregnancy.
  
  
  METHODS
  64 pregnant women diagnosed with syphilis by serological assays were divided into treated group and untreated group according to whether they accepted full-dose treatment against syphilis or not. Patients in the treated group accepted benzathine penicillin(2.4 million units once per week) intramuscular injection for three weeks. The outcome of pregnan after treatment was observed and compared between the two groups.
  
  
  RESULTS
  There were 5 cases of primary syphilis (7.8%), 29 cases of secondary syphilis (45.3%), and 30 cases of latent syphilis (46.9%) among the 64 cases. The occurrences of premature birth, fetal intrauterine death, and stillbirth were 0, and 3 cases of congenital syphilis in total 13 cases who carried pregnancy to term in the treated group; while 4, 11, 3, and 10 in the untreated group respectively. In treated group, the 3 babies with congenital syphilis were born from 10 mothers received treatment after 24 gestational weeks, while no congenital syphilis in the 3 women started treatment before 24 weeks.
  
  
  CONCLUSIONS
  Pregnant syphilis is prone to be misdiagnosed because of its slight symptom, so it is especially important to screen syphilis as a routine among high risk pregnant women. Premature, fetal death and congenital syphilis can be well controlled through regular and early treatment during pregnancy, yet congenital syphilis can not be avoided completely.
