Vaginal application of a chemotherapeutic agent before legal abortion. A way of reducing infectious complication?

In an attempt to reduce the incidence of infectious complications after first trimester legal abortion 199 healthy, early pregnant women were treated with chloroquinaldol (SterosanR vaginal jelly) during six days before their vacuum aspiration. A group of 291 women served as control. In the treatment group 18 women (9%) had a postoperative gynecological infection while this condition was found in 37 women (12.8%) in the control group. This difference is not statistically significant. The authors conclude that preoperative prophylactic treatment with Sterosan vaginal jelly does not seem to reduce postoperative infectious complications after first trimester legal abortions.

Evaluation of the in vivo efficacy of a new vaginal contraceptive agent in stumptailed macaques.

The effect of precoital vaginal placement of three spermicidal formulations on postcoitally recovered vaginal and cervical spermatozoa was compared. Periovulatory stumptailed macaque monkeys were administered intravaginally 1 ml of Ramses Contraceptive Vaginal Jelly (C. Schmid Products Company, Little Fall, NJ), or a pluronic gel formulation containing 0, 0.1, or 1.0% of a new spermicidal compound, RS-37367. All spermicide-containing formulations reduced the motility of both vaginal and cervical sperm, compared with the gel containing no spermicide. The 1.0% RS-37367 formulation was particularly effective. No motile spermatozoa were recovered from either location, and only 0.5% of the numbers of cervical spermatozoa recovered in control animals were recoverable from this treatment group (P less than 0.0003). The formulation containing 0.1% RS-37367 appeared to be bioequivalent to the Ramses formulation containing 5% nonoxynol-9. These in vivo results support previous in vitro comparisons in which RS-37367 was estimated to be 50 times as potent a spermatostatic agent as nonoxynol-9.

Fourteen-day safety and acceptability study of 6% cellulose sulfate gel: a randomized double-blind Phase I safety study.

BACKGROUND: Topical microbicides against the human immunodeficiency virus (HIV) 1 that are nonirritating to the female genital epithelium are urgently needed to slow the heterosexual spread of HIV infection. Products that are also effective contraceptives provide additional benefits. Cellulose sulfate (CS) is a noncytotoxic antifertility agent that exhibits in vitro antimicrobial activity against sexually transmitted pathogens, including HIV. METHODS: We performed a multicenter, Phase I, placebo-controlled, randomized study to evaluate the genital toxicity of CS. Two cohorts of healthy women used 3.5 ml of 6% CS gel or 3.5 ml of K-Y Jelly, vaginally, bid, for 14 days. The first cohort was sexually abstinent, and the second cohort was sexually active. RESULTS: CS was associated with only a slightly higher odds ratio (OR) of symptoms of minor urogenital irritation compared to the inactive lubricant K-Y Jelly (OR=2.02, 95% confidence interval=0.90-4.53). In addition, there were minor shifts in some genital flora, but there was no evidence of greater inflammation as evidenced by few colposcopic findings, decreased influx of polymorphonuclear cells and minimal changes in proinflammatory cytokines. Moreover, both products appeared acceptable to most women. Product leakage was identified as more of a problem in sexually abstinent women, but less so in women using the product for sexual intercourse, as would be the case in actual practice. CONCLUSION: CS was safe for twice-daily use for 14 days. CS is appropriate for future studies in effectiveness trials.

Colposcopic evaluation of a vaginal gel formulation of iota-carrageenan.

There is an urgent need to develop safe, effective, and acceptable vaginal products for the prevention of sexually transmitted infections. Preliminary in vitro results suggest that vaginal formulations of sulfated polysaccharides, including iota-carrageenan, have the potential to block mucosal transmission of human immunodeficiency virus (HIV). Twenty-five women in five sites participated in Phase I trials to evaluate the safety of a formulation containing iota-carrageenan (PC 213). The results of this study indicate that a 5 mL 2% gel formulation of iota-carrageenan is not associated with significant irritation of the female reproductive tract when administered once daily in the absence of sexual intercourse. Given the small number of participants in this initial study, careful observation for potential irritation must also be included in larger studies of this and other vaginal formulations.

Frequency of non-hormonal contraception around conception and association with congenital malformations in offspring.

A case-control study using data on deliveries in the mid-1970s at five Connecticut hospitals (cases, n = 1427; controls, n = 3001) found little relationship between delivery of a malformed infant and use by the mother of nonhormonal contraceptive methods at conception. Of particular interest was the lack of an association with use of the rhythm method (odds ratio (OR) = 1.02, 95% confidence limits (CL) = 0.73, 1.42), spermicides (OR = 1.26, 95% CL = 0.85, 1.85) at conception and a modest association for the intrauterine device (IUD) one week before conception (OR = 1.99, 95% CL = 0.98, 4.04). Continued use of the IUD after conception may further increase the risk for malformations but this observation was statistically unreliable in the present study. Mothers of newborns with cleft lip and palate (OR = 2.91) and congenital hydrocele (OR = 4.64) were more frequent rhythm users at conception, and mothers of newborns with multiple anomalies had more recent IUD exposure (OR = 9.87), but these and all other specific congenital malformation groups were not significantly related to any non-hormonal contraceptive after adjustment for multiple observations. Potentially confounding maternal risk factors were controlled.
