Screening for chlamydia and gonorrhea cervicitis and implications for pregnancy outcome: Are we testing and treating at the right time?

OBJECTIVE: To evaluate the effect of gonorrheal and chlamydial cervicitis (GCC) on the risk of preterm labor (PTL) and preterm premature rupture of membranes (PPROM). STUDY DESIGN: A large cross-sectional sample of patients (N=1,120) was studied. Data on samples for GCC and pregnancy outcome were entered into a database from a retrospective chart review. RESULTS: There were 1,120 pregnancies with adequate data for analysis. Of those pregnancies 933 were unaffected by GCC, and 187 were affected. The rates of preterm delivery were 17.79% and 16.58% for GCC-negative and GCC-positive pregnancies, respectively. PPROM occurred in 3.97% and 2.67% of GCC-negative and GCC-positive pregnancies, respectively. PTL occurred in 8.25% and 8.02% of GCCnegative and GCC-positive pregnancies, respectively. No outcomes met statistical significance. When pregnancy outcomes were analyzed by trimester of infection, there was a higher risk of preterm delivery but not preterm labor with earlier infection. This did meet statistical significance. There was a trend towards lower rate of cesarean section in the infected group of patients, which did not meet statistical significance. CONCLUSION: Maternal infection with gonorrhea and/or chlamydia is not associated with PPROM or PTL.
