title: Screening and treatment for sexually transmitted infections in pregnancy.
abstract: Many sexually transmitted infections are associated with adverse pregnancy outcomes. The Centers for Disease Control and Prevention recommends screening all pregnant women for human immunodeficiency virus infection as early as possible. Treatment with highly active antiretroviral therapy can reduce transmission to the fetus. Chlamydia screening is recommended for all women at the onset of prenatal care, and again in the third trimester for women who are younger than 25 years or at increased risk. Azithromycin has been shown to be safe in pregnant women and is recommended as the treatment of choice for chlamydia during pregnancy. Screening for gonorrhea is recommended in early pregnancy for those who are at risk or who live in a high-prevalence area, and again in the third trimester for patients who continue to be at risk. The recommended treatment for gonorrhea is ceftriaxone 125 mg intramuscularly or cefixime 400 mg orally. Hepatitis B surface antigen and serology for syphilis should be checked at the first prenatal visit. Benzathine penicillin G remains the treatment for syphilis. Screening for genital herpes simplex virus infection is by history and examination for lesions, with diagnosis of new cases by culture or polymerase chain reaction assay from active lesions. Routine serology is not recommended for screening. The oral antivirals acyclovir and valacyclovir can be used in pregnancy. Suppressive therapy from 36 weeks' gestation reduces viral shedding at the time of delivery in patients at risk of active lesions. Screening for trichomoniasis or bacterial vaginosis is not recommended for asymptomatic women because current evidence indicates that treatment does not improve pregnancy outcomes.
