Objective:
To evaluate prospectively the 1989 Centers for Disease Control recommendations for treatment of gonorrhea in pregnancy.
Methods:
Two hundred fifty-two women referred with probable endocervical gonorrhea had pre-treatment endocervical, rectal, and oral cultures for Neisseria gonorrhoeae and direct fluorescent antibody testing for Chlamydia trachomatis. They were assigned randomly to receive ceftriaxone 250 mg intramuscularly (IM), spectinomycin 2 g IM, or amoxicillin 3 g orally plus probenecid 1 g orally. Treatment was unblinded and in a 1:1:1 distribution.
Results:
Two hundred forty-five women (97%) had endocervical infection, 68 (27%) had rectal infection, and 17 (7%) had pharyngeal infection. One hundred two of 252 women (40%) had concomitant endocervical C trachomatis. The overall efficacy was 235 of 252 subjects (93%) (95% confidence interval [CI] 90.1-96.4%). Ceftriaxone was effective in 80 of 84 cases (95%) (95% CI 90.6-99.9%), amoxicillin with probenecid was effective in 75 of 84 cases (89%) (95% CI 82.5-96%), and spectinomycin was effective in 80 of 84 cases (95%) (95% CI 90.6-99.9%). No significant difference was noted in overall efficacy or by site of infection. There was no increased incidence of congenital malformations in the offspring spring of any treatment group.
Conclusions:
Ceftriaxone and spectinomycin are safe and effective for the treatment of gonorrhea in pregnancy. Amoxicillin with probenecid has lower efficacy and is not recommended for treatment of gonococcal infection in pregnancy.
