Drugs five years later. Spectinomycin.

A single intramuscular injection of 0.2 g of spectinomycin hydrochloride is highly effective for the treatment of uncomplicated anogenital infections with Neisseria gonorrhoeae. Spectinomycin hydrochloride is indicated for uncomplicated anogenital gonococcal infections in men and women who cannot receive penicillin or probenecid, and is the drug of choice for the retreatment of patients with uncomplicated anogenital gonococcal infection who have not responded to other antibiotics. A single dose of spectinomycin does not appear to be reliably effective in the treatment of gonococcal pharyngitis. Preliminary reports indicate that multiple-dose schedules of spectinomycin will prove to be effective in gonococcal pelvic inflammatory disease and disseminated gonococcal infection. In the dosage used for gonococcal infections, spectinomycin has little effect on infection with Treponema pallidum. Evaluation of this antibiotic against other microorganisms suggests little utility for this agent in conditions other than gonococcal infections.

Reevaluation of the role of T-mycoplasmas in nongonococcal urethritis.

T-mycoplasmas have been associated with nongonococcal urethritis (NGU) in studies in which these organisms were found to be more prevalent among men with NGU than among control groups of men. In none of these studies were the groups matched for sexual experience, a variable which we have shown to be an important determinant of colonization with T-mycoplasmas. We obtained urethral cultures for genital mycoplasmas from men presenting to the Boston City Hospital with gonococcal urethritis and with NGU, and from men of comparable sexual experience who did not have urethritis. Colonization with T-mycoplasmas was no more prevalent among men who had NGU than among the men who did not have urethritis. These data raise some serious questions about the role of T-mycoplasmas in nongonococcal urethritis.

Genital mycoplasmal infections: their relation to prematurity and other abnormalities of reproduction.

The genital mycoplasmas, Mycoplasma hominis and Ureaplasma urealyticum eT-mycoplasmas) are common vaginal organisms. They are acquired primarily through sexual contact. There is evidence, some of it highly suggestive, linking the genital mycoplasmas to involuntary infertility, spontaneous abortion and low birth weight. Additional controlled treatment studies are needed in each of these areas to assess fully the role of the genital mycoplasmas. M. hominis has the potential to invade the blood stream and is responsible for some instances of fever following abortion and of postpartum fever.

Isolation of genital mycoplasmas from blood obtained shortly after vaginal delivery.

Blood obtained from three hundred and twenty-seven women within a few minutes of vaginal delivery was cultured for genital mycoplasmas (Mycoplasma hominis and T mycoplasmas). Twenty-six (8%) of the women had genital mycoplasmas isolated from their blood. Ten women had blood-cultures which contained M. hominis. Fifteen women had blood-cultures which contained T mycoplasmas. Both M. hominis and T mycoplasmas were isolated from the blood of one woman. Only one of two hundred and seventy-three blood-cultures obtained 1 or more days after delivery contained mycoplasmas. The isolation of M. hominis, but not of T mycoplasmas, from the blood was associated with vaginal colonisation and a serological response to the homologous isolate. Two of ten women whose blood contained M. hominis gave birth to stillborn infants. In contrast, there were only four (1.3%) stillbirths among the infants born to the three hundred and one women whose blood did not contain mycoplasmas. This difference is statistically significant.

Comparison of spectinomycin hydrochloride and aqueous procaine penicillin G in the treatment of uncomplicated gonorrhea.

Men and women with uncomplicated gonorrhea were randomly assigned to receive aqueous procaine penicillin G (2,400,000 U for men; 2,400,000 U daily for 2 days for women) or spectinomycin hydrochloride (2.0 g for men; 4.0 g for women). Among men who returned for post-treatment evaluation within 10 days, treatment failures were noted among 16 (20.3%) of 79 men who received penicillin and 8 (9.5%) of 84 men who received spectinomycin (P < 0.1). Similarly, 6 (13.3%) of 45 women who received penicillin and 3 (6.5%) of 46 women who received spectinomycin had positive endocervical cultures for Neisseria gonorrhoeae at the time of the post-treatment examination (P = not significant).
