A randomized trial of double vs single-dose etonogestrel implant to overcome the interaction with efavirenz-based antiretroviral therapy.

BACKGROUND: Concomitant use of efavirenz-based antiretroviral therapy and a standard-dose etonogestrel contraceptive implant led to 82% lower etonogestrel exposure when compared with women who do not receive antiretroviral therapy. The clinical impact of this reduced exposure is supported by retrospective cohort evaluations that demonstrated higher rates of unintended pregnancies when contraceptive implants were combined with efavirenz. We hypothesized that placement of 2 etonogestrel implants in those taking efavirenz-based antiretroviral therapy could increase etonogestrel exposure and improve measures of contraceptive efficacy. OBJECTIVE: This study compared the rate of ovulation and etonogestrel pharmacokinetics among women on efavirenz-based antiretroviral therapy who received 2 etonogestrel implants (136 mg; double implant group) in comparison with those who received 1 etonogestrel implant (68 mg; control group). STUDY DESIGN: This randomized, open-label study enrolled Ugandan women with regular menstrual periods who were receiving efavirenz-based antiretroviral therapy for the treatment of HIV. Participants were randomized 1:1 to the double implant or control group, and the etonogestrel implant(s) were placed in the same arm at enrollment. All participants used a copper intrauterine device to prevent pregnancy. Ovulation was evaluated by weekly serum progesterone concentrations measured over 4 consecutive weeks at months 3 (weeks 9-12), 6 (weeks 21-24), and 12 (weeks 45-48). Progesterone concentrations >3 ng/mL were interpreted as ovulation. The ovulation rate in each group was compared using Fisher's exact tests for each month and generalized estimating equations over 48 weeks. Plasma was collected at day 3 and weeks 1, 4, 12, 24, 36, and 48 after implant placement and analyzed using a validated liquid chromatography-triple quadrupole mass spectrometry method for etonogestrel. Etonogestrel concentrations were summarized as median (interquartile range) and compared between groups by geometric mean ratio with 90% confidence intervals. RESULTS: All participants (n=72) were cisgender Ugandan women with a median age of 31 years (interquartile range, 29-36), and 36 participants were enrolled in each study group. Two participants in the control group discontinued the trial; 1 at week 1 because of undetected pregnancy at entry and another at week 45 because of clinically significant depression. There were 47 ovulations over 104 person-months (45%) in 25 of 34 participants in the control group, and 2 ovulations over 108 person-months (2%) in 2 of 36 participants in the double implant group (month 3: 11 [31%] vs 0 [0%]; month 6: 17 [49%] vs 0 [0%]; month 12: 19 [56%] vs 2 [6%], respectively; all P<.001). The odds of ovulation were reduced by 97.7% (95% confidence interval, 90.1-99.5) in the double implant group over 48 weeks. At each time point, etonogestrel concentration was more than 2-fold higher in the double implant group than in the controls (geometric mean ratio, 2.30-2.83) with a geometric mean ratio of 2.83 (90% confidence interval, 1.89-3.35) at week 48. There were no differences in the adverse events between groups and no participant discontinued because of adverse events. CONCLUSION: Over 48 weeks of combined use, placing 2 etonogestrel implants suppressed ovulation and increased plasma etonogestrel exposure when compared with 1 etonogestrel implant among women on efavirenz-based antiretroviral therapy. Doubling the dose of etonogestrel during efavirenz-based antiretroviral therapy could improve contraceptive effectiveness.

Impact of Dapivirine and Placebo Vaginal Rings on the Microbiota of Adolescent, Lactating, and Postmenopausal Females.

BACKGROUND: A 25-mg dapivirine vaginal ring has been demonstrated to reduce risk of human immunodeficiency virus (HIV) acquisition in nonpregnant adult women. In this secondary analysis of studies conducted in US adolescent, lactating, and postmenopausal females, vaginal microbiota was assessed prior to and after ring use, and between dapivirine and placebo ring users. METHODS: Vaginal fluid swabs were collected before and after product use for the evaluation of microbiota using Nugent criteria, quantitative culture, and quantitative polymerase chain reaction. RESULTS: Vaginal ring use did not impact bacterial vaginosis prevalence among the 3 populations and was associated with minimal shifts in microbiota. Adolescents in both arms demonstrated an increased prevalence of Lactobacillus crispatus and a decrease in quantity of Megasphaera lornae. Postmenopausal active and placebo ring users demonstrated an increased prevalence of lactobacilli and non-albicans yeast, while dapivirine ring users demonstrated an increased prevalence of Candida albicans and increased quantity of group B Streptococcus and non-albicans yeasts. Prevotella species were increased in lactating women, whereas Prevotella timonensis increased in prevalence and concentration among adolescent and postmenopausal females and Prevotella bivia increased in prevalence among adolescent dapivirine ring users. CONCLUSIONS: Dapivirine vaginal ring use was associated with minimal changes in the vaginal microbiota that are likely not clinically significant.

A Randomized Controlled Trial of Ceftriaxone and Doxycycline, With or Without Metronidazole, for the Treatment of Acute Pelvic Inflammatory Disease.

BACKGROUND: Anaerobic organisms are important pathogens in acute pelvic inflammatory disease (PID). The currently recommended PID regimen of a single dose of ceftriaxone and doxycycline for 14 days has limited anaerobic activity. The need for broader anaerobic coverage is unknown and concerns have been raised about metronidazole tolerability. METHODS: We conducted a randomized, double-blind, placebo-controlled trial comparing ceftriaxone 250 mg intramuscular single dose and doxycycline for 14 days, with or without 14 days of metronidazole in women with acute PID. The primary outcome was clinical improvement at 3 days following enrollment. Additional outcomes at 30 days following treatment were the presence of anaerobic organisms in the endometrium, clinical cure (absence of fever and reduction in tenderness), adherence, and tolerability. RESULTS: We enrolled 233 women (116 to metronidazole and 117 to placebo). Clinical improvement at 3 days was similar between the 2 groups. At 30 days following treatment, anaerobic organisms were less frequently recovered from the endometrium in women treated with metronidazole than placebo (8% vs 21%, P < .05) and cervical Mycoplasma genitalium was reduced (4% vs 14%, P < .05). Pelvic tenderness was also less common among women receiving metronidazole (9% vs 20%, P < .05). Adverse events and adherence were similar in each treatment group. CONCLUSIONS: In women treated for acute PID, the addition of metronidazole to ceftriaxone and doxycycline was well tolerated and resulted in reduced endometrial anaerobes, decreased M. genitalium, and reduced pelvic tenderness compared to ceftriaxone and doxycycline. Metronidazole should be routinely added to ceftriaxone and doxycycline for the treatment of women with acute PID. CLINICAL TRIALS REGISTRATION: NCT01160640.

Diagnosis and Treatment of Vaginal Discharge Syndromes in Community Practice Settings.

BACKGROUND: Although vaginal symptoms are common, diagnosis of bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), and Trichomonas vaginalis (TV) is not standardized. Diagnostic approaches and appropriateness of treatment were evaluated for women with symptoms of vaginitis who were seeking care at community practice sites. METHODS: Three hundred three symptomatic women, across 8 University of Pittsburgh Medical Center-affiliated clinics, were evaluated per standard office-based practice. Four of 5 vaginal swabs (1 cryopreserved) were collected for a US Food and Drug Administration-authorized nucleic acid amplification test (NAAT) for vaginitis/vaginosis diagnosis; Nugent scoring (BV); yeast culture (VVC); and a second NAAT (for TV). Two hundred ninety women had evaluable samples. Medical record extraction facilitated verification of treatments prescribed within 7 days of the index visit and return visit frequency within 90 days. RESULTS: Women had a mean age of 29.4 ± 6.5 years, 90% were not pregnant, 79% were of white race, and 38% reported vaginitis treatment within the past month. Point-of-care tests, including vaginal pH (15%), potassium hydroxide/whiff (21%), and wet mount microscopy (17%), were rarely performed. Of the 170 women having a laboratory-diagnosed cause of vaginitis, 81 (47%) received 1 or more inappropriate prescriptions. Of the 120 women without BV, TV, or VVC, 41 (34%) were prescribed antibiotics and/or antifungals. Among women without infectious vaginitis, return visits for vaginitis symptoms were more common among women treated empirically compared to those not receiving treatment (9/41 vs 5/79, P = .02). CONCLUSIONS: Within a community practice setting, 42% of women having vaginitis symptoms received inappropriate treatment. Women without infections who received empiric treatment were more likely have recurrent visits within 90 days. CLINICAL TRIALS REGISTRATION: NCT03151928.

Impact of contraceptive initiation on vaginal microbiota.

BACKGROUND: Data evaluating the impact of contraceptives on the vaginal microbiome are limited and inconsistent. OBJECTIVE: We hypothesized that women initiating copper intrauterine device use would have increased bacterial vaginosis and bacterial vaginosis-associated microbes with use compared to women initiating and using hormonal contraceptive methods. STUDY DESIGN: Vaginal swabs (N = 1047 from 266 participants seeking contraception) for Nugent score determination of bacterial vaginosis and quantitative polymerase chain reaction analyses for assessment of specific microbiota were collected from asymptomatic, healthy women aged 18-35 years in Harare, Zimbabwe, who were confirmed to be free of nonstudy hormones by mass spectrometry at each visit. Contraception was initiated with an injectable (depot medroxyprogesterone acetate [n = 41], norethisterone enanthate [n = 44], or medroxyprogesterone acetate and ethinyl estradiol [n = 40]), implant (levonorgestrel [n = 45] or etonogestrel [n = 48]), or copper intrauterine device (n = 48) and repeat vaginal swabs were collected after 30, 90, and 180 days of continuous use. Self-reported condom use was similar across all arms at baseline. Quantitative polymerase chain reaction was used to detect Lactobacillus crispatus, L jensenii, L gasseri/johnsonii group, L vaginalis, L iners, Gardnerella vaginalis, Atopobium vaginae, and Megasphaera-like bacterium phylotype I from swabs. Modified Poisson regression and mixed effects linear models were used to compare marginal prevalence and mean difference in quantity (expressed as gene copies/swab) prior to and during contraceptive use. RESULTS: Bacterial vaginosis prevalence increased in women initiating copper intrauterine devices from 27% at baseline, 35% at 30 days, 40% at 90 days, and 49% at 180 days (P = .005 compared to marginal prevalence at enrollment). Women initiating hormonal methods had no change in bacterial vaginosis prevalence over 180 days. The mean increase in Nugent score was 1.2 (95% confidence interval, 0.5-2.0; P = .001) in women using copper intrauterine devices. Although the frequency and density of beneficial lactobacilli did not change among intrauterine device users over 6 months, there was an increase in the log concentration of G vaginalis (4.7, 5.2, 5.8, 5.9; P = .046) and A vaginae (3.0, 3.8, 4.6, 5.1; P = .002) between baseline and 30, 90, and 180 days after initiation. Among other contraceptive groups, women using depot medroxyprogesterone acetate had decreased L iners (mean decrease log concentration = 0.8; 95% confidence interval, 0.3-1.5; P = .004) and there were no significant changes in beneficial Lactobacillus species over 180 days regardless of contraceptive method used. CONCLUSION: Copper intrauterine device use may increase colonization by bacterial vaginosis-associated microbiota, resulting in increased prevalence of bacterial vaginosis. Use of most hormonal contraception does not alter vaginal microbiota.

Use of Nucleic Acid Amplification Testing for Diagnosis of Extragenital Sexually Transmitted Infections.

Nucleic acid amplification testing (NAAT) is the preferred method to detect Chlamydia trachomatis and Neisseria gonorrhoeae, but no commercial tests are cleared by the U.S. Food and Drug Administration for use with extragenital swab samples. This study evaluated the performance of the Gen-Probe Aptima Combo2 assay (Aptima) and the Cepheid Xpert CT/NG assay (Xpert) to detect C. trachomatis and N. gonorrhoeae in rectal and pharyngeal samples from 224 men and 175 women reporting a history of anal receptive sexual intercourse. Discordant results between the NAATs were repeated using the assays APTIMA CT or APTIMA GC, which target alternate primers, as the confirmatory tests. C. trachomatis was detected from 59 rectal swabs and 8 pharyngeal samples, with 97.7% and 99.5% agreement between the two test systems, respectively. For C. trachomatis, Xpert was 95% sensitive (95% CI, 86 to 99%) and Aptima was 92% sensitive (95% CI, 81 to 97%) from rectal swabs, while both systems were 100% sensitive from pharyngeal samples. N. gonorrhoeae was detected from 30 rectal and 40 pharyngeal samples, with 99.5% and 97.5% agreement between the two test systems. The sensitivity of Xpert for N. gonorrhoeae from rectal swabs was 100% (95% CI, 88 to 100%) versus 93% (95% CI, 78 to 99%) for Aptima. From pharyngeal swab samples, Xpert was 98% sensitive (95% CI, 87 to 99.9%) versus 93% (95% CI, 80 to 98%) for Aptima. For C. trachomatis, neither system was >95% sensitive from the rectum, though both were >99.5% specific. For N. gonorrhoeae, Xpert had higher sensitivity than Aptima, but with more false positives from pharyngeal samples.

Preferred Physical Characteristics of Vaginal Film Microbicides for HIV Prevention in Pittsburgh Women.

Unprotected heterosexual intercourse is the leading cause of HIV acquisition in women. Due to the complex nature of correct and consistent condom use by both men and women, developing alternative female-controlled HIV prevention options is a global health priority. Vaginal films containing antiretroviral drugs are a potential delivery system for the prevention of HIV acquisition through sexual contact. In this study, we explored women's preferences regarding physical characteristics of microbicide vaginal films through questionnaires and focus groups. Eighty-four sexually active, ethnically diverse women 18-30 years of age from Pittsburgh, Pennsylvania, participated in the study. Women visually and manually examined a variety of vaginal films, as well as three other vaginal products undergoing evaluation for HIV prevention: tablet, ring, and gel. Means and standard deviations or frequencies and 95 % confidence intervals were calculated for questionnaire data. Focus groups were audio-recorded, transcribed verbatim, and coded for content analysis. Women most frequently preferred vaginal films to be smooth and thin (63 %), translucent (48 %), and 2″ × 2″ square size (36 %). Driving these preferences were five major themes: ease and accuracy of use, desire for efficacy, discretion, intravaginal comfort and minimal impact, and minimizing disruption of sexual mood/activities. Women's preferences for various microbicide vaginal film physical attributes represented a balance of multiple values. In general, women desired a comfortable, efficacious, easy to use, and minimally intrusive product.

Bacterial species colonizing the vagina of healthy women are not associated with race.

The vaginal microbiota of 36 white versus 25 black asymptomatic women were compared using both cultivation-dependent and -independent identification. Significant differences by race were found in colonization and density of bacterial species. However, exclusion of 12 women with bacterial vaginosis by Nugent criteria resulted in no significant differences by race.

Survival of vaginal microorganisms in three commercially available transport systems.

Transport systems are used to collect and maintain the viability of microorganisms. Two Amies media based transport systems, BD CultureSwab™ MaxV(+) Amies Medium without Charcoal (MaxV(+)) and Fisherfinest® with Amies gel Transport Medium without charcoal (Fisherfinest®) were compared to a Cary-Blair media based transport system, Starswab® Anaerobic Transport System (Starswab®), for their capacity to maintain the viability of 17 clinical microorganisms commonly isolated from the vagina (Lactobacillus crispatus, L. jensenii, L. iners, group B streptococci, Candida albicans, Escherichia coli, Enterococcus faecalis, Atopobium vaginae, Peptoniphilus harei, Mycoplasma hominis, Gardnerella vaginalis, Dialister microaerophilus, Mobiluncus curtisii, Prevotella amnii, P. timonensis, P. bivia, and Porphyromonas uenonis). Single swabs containing mixtures of up to five different species were inoculated in triplicate and held at 4 °C and room temperature for 24, 48, 72, and 96 h (h). At each time point, swabs were eluted into a sterile salt solution, serially diluted, inoculated onto selected media, and incubated. Each colony type was quantified and identified. A change in sample stability was reported as a ≥1 log increase or decrease in microorganism density from baseline. Overall, the viability of fastidious anaerobes was maintained better at 4 °C than room temperature. At 4 °C all three transport systems maintained the viability and prevented replication of C. albicans, E. faecalis, GBS, and E. coli. Microorganisms having a ≥1 log decrease in less than 24 h at 4 °C included A. vaginae, G. vaginalis, and P. uenonis in Starswab®, L. iners, A. vaginae, and P. amnii in MaxV(+), and A. vaginae, G. vaginalis, P. bivia, and P. amnii in Fisherfinest®. At 48 h at 4 °C, a ≥1 log decrease in concentration density was observed for P. harei and P. amnii in Starswab®, G. vaginalis, P. bivia and P. uenonis in MaxV(+), and L. iners, P. harei, P. timonensis, and P. uenonis in Fisherfinest®. Overall, at 4 °C the viability and stability of vaginal microorganisms was maintained better in the Cary-Blair based transport system (Starswab®) than in the two Amies based transport systems.

Patterns of Extragenital Chlamydia and Gonorrhea in Women and Men Who Have Sex With Men Reporting a History of Receptive Anal Intercourse.

BACKGROUND: Screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) in men who have sex with men is risk based. Despite high frequencies of oral and receptive anal intercourse (RAI) among women, extragenital screening is not recommended. METHODS: Women (n = 175) and men who have sex with men (n = 224) primarily recruited from a sexually transmitted infection clinic reporting a lifetime history of RAI completed a structured questionnaire and clinician-collected swab samples from the rectum, pharynx, vagina (women), and urine (men). CT and GC were detected using 2 commercial nucleic acid amplification tests (Aptima Combo 2; Hologic, Inc, Bedford, MA; Xpert CT/NG, Cepheid Innovation, Sunnyvale, CA). RESULTS: The median age of the population was 26 years, 62% were white, and 88% were enrolled from a sexually transmitted disease clinic. Men were more likely than women to have GC (22.8% vs. 3.4%) and CT (21.9% vs. 12.6%). In men versus women, GC was detected in 16.5% versus 2.3% of pharyngeal swabs, 11.6% versus 2.3% of rectal swabs, and 5.4% versus 2.9% of urine samples or vaginal swabs. C. trachomatis was detected in 2.2% versus 1.7% of pharyngeal swabs, 17.4% versus 11.4% of rectal swabs, and 4.5% versus 10.3% for urogenital sites in men versus women. Overall 79.6% of CT and 76.5% of GC in men and 18.2% of CT and 16.7% of GC in women were detected only in the pharynx or rectum. CONCLUSION: Reliance on urogenital screening alone misses most of GC and CT in men and more than 15% of infections in women reporting RAI.

The effect of menopause on the innate antiviral activity of cervicovaginal lavage.

OBJECTIVE: Reproductive hormones are known to impact innate mucosal immune function of the lower genital tract. Our objectives were to determine the effect of hormonal status on intrinsic antiviral (herpes simplex virus [HSV]-1, HSV-2, and human immunodeficiency virus [HIV]-1) activity of cervicovaginal lavage (CVL). STUDY DESIGN: CVL was collected from 165 asymptomatic women including postmenopausal women (n = 29); women not on contraception in days 1-14 (n = 26) or days 15-28 (n = 27) of the menstrual cycle; and women using the levonorgestrel intrauterine device (n = 28), depot medroxyprogesterone acetate (n = 28), or combined oral contraceptives (n = 27). The anti-HSV-1/-2 and the anti-HIV-1 activity of the CVL were measured using plaque assays and the Jurkat-Tat-CCR5 assay, respectively. RESULTS: CVL from all of the groups had modest antiviral activity. Anti-HIV-1 activity was decreased in CVL from postmenopausal women when compared to premenopausal women (11% vs 34%, P = .002). However, there was no difference in anti-HIV-1 activity among premenopausal women regardless of phase of menstrual cycle or contraceptive use. Anti-HIV-1 activity was associated with the protein content of the CVL (r = 0.44, P < .001). There was no difference in anti-HSV-1 or -2 activity by hormonal group. CONCLUSION: Menopause is associated with decreased innate HIV-1 activity in the lower genital tract, suggesting that factors in the vaginal fluid could play a role in increased susceptibility of HIV-1 infection in postmenopausal women. Hormonal contraceptive use, menopause, and phase of menstrual cycle did not have a measurable impact on the intrinsic anti-HSV-1 or -2 activity.

Text Messaging to Improve Preventive Health Attitudes and Behaviors During Pregnancy: A Prospective Cohort Analysis.

OBJECTIVE: To delineate the effects of text messages sent to pregnant women to promote preventive health beliefs and behaviors. STUDY DESIGN: A prospective cohort analysis was performed among women who participated in a randomized, controlled trial aimed at improving preventive health. Participants (158 pregnant women enrolled from 2010-2012) received 12 weekly text messages encouraging preventive health behaviors (tobacco cessation, condom use for disease prevention, nutrition optimization, seat belt use, breastfeeding). Pre- and postintervention surveys assessed preventive health beliefs and practices. RESULTS: At follow-up, participants agreed that receiving text messages changed their beliefs about targeted preventive health behaviors: smoking (50%), sexually transmitted disease prevention (72%), prenatal vitamins (83%), seat belt use (68%), nutritious foods (84%), and breastfeeding (68%). Many participants reported more frequent engagement in target behaviors at follow-up than at baseline: decreased tobacco use (among 41% of smokers), more consistent condom use (among 7% of sexually active participants), more prenatal vitamin intake (32%), more frequent seatbelt use (32%), more frequent healthy food intake (41%), and intention to breastfeed longer (21%). CONCLUSION: Pregnant women receiving text messages promoting preventive health reported improvements in targeted beliefs and behaviors, suggesting that text messaging may be used for health promotion during pregnancy.

The effects of reproductive hormones on the physical properties of cervicovaginal fluid.

OBJECTIVE: The purpose of this study was to determine the impact of contraception, menopause, and vaginal flora on the physical and biochemical properties of cervicovaginal fluid (CVF). STUDY DESIGN: Vaginal swabs, CVF, and cervicovaginal lavage (CVL) were collected from a total of 165 healthy asymptomatic women including: postmenopausal women (n = 29), women in the proliferative (n = 26) or follicular (n = 27) phase, and women using the levonogestrel intrauterine device (n = 28), depomedroxyprogesterone acetate (n = 28) or combined oral contraceptives (n = 27). Vaginal smears were evaluated using the Nugent score. The osmolality, viscosity, density, and pH of CVL samples were measured. RESULTS: CVL from postmenopausal women and women with abnormal vaginal flora was less viscous and had higher pH than premenopausal women and women with normal flora, respectively. Women using hormonal contraceptives had more viscous CVL as compared with premenopausal women not using hormonal contraceptives, but this increase in viscosity was mitigated in the presence of bacterial vaginosis. Women using depomedroxyprogesterone acetate had less total protein in the CVL as compared with women using the levonogestrel intrauterine device, and had similar protein content when compared with postmenopausal women. CONCLUSION: The differences in CVL protein content between depomedroxyprogesterone acetate and levonogestrel intrauterine device suggest that type of progesterone and route of delivery impact the vaginal environment. Contraceptive hormone users had more viscous CVL than women not using contraceptives. However, the presence of bacterial vaginosis impacted both the pH and viscosity (regardless of hormonal contraceptive use), demonstrating that vaginal flora has a greater impact on the physical properties of CVF than reproductive hormones.

Survival of Trichomonas vaginalis in wet preparation and on wet mount.

OBJECTIVES: Microscopy is an insensitive method for detection of Trichomonas vaginalis, but is widely used because it is both rapid and inexpensive. Diagnosis of trichomoniasis by microscopy requires that motile forms be identified in vaginal fluid samples. However, microscopy cannot always be performed immediately after sample collection. The objective of this study was to assess the impact of sample storage at room temperature on trichomonad motility. METHODS: Vaginal swab samples from 77 women positive for T vaginalis infection were collected to determine the impact of storage on wet preparations (swabs in plastic tubes with saline) and wet mounts (samples placed onto a glass slide with a coverslip). Samples were read at 400× every 30 min for the first hour and then once per hour thereafter until there were no motile trichomonads observed. RESULTS: For wet preparations, motility was 100% at 30 min, 99% at 60 min and decreased by 3%-15% each subsequent hour, with samples having a lower density of trichomonads losing motility more quickly. Trichomonad motility diminished more rapidly in wet mounts compared with wet preparations, with a 20% decrement in motility in 60 min. CONCLUSIONS: These data suggest that vaginal fluid samples for diagnosis of trichomoniasis should be stored in saline rather than on microscope slides until they are examined under the microscope and samples should be evaluated by microscopy within an hour of collection. These findings also suggest that clinical sites which cannot perform microscopy within 1 h of sample collection should consider the use of other diagnostic tests.

Perceptions and acceptance of immunization during pregnancy.

OBJECTIVE: To estimate patients' perceptions of the need, safety and acceptability of vaccination during pregnancy. STUDY DESIGN: An office-based survey was offered to patients presenting for obstetric and gynecologic care from December 2007 to July 2008 at an academic women's hospital. The anonymous questionnaire assessed demographics, medical and vaccination history, interest in receiving vaccines, and beliefs about vaccination safety. Data were evaluated using descriptive statistics and chi2 analyses. RESULTS: A total of 1,436 completed surveys were available for analysis, including 573 from pregnant women. Pregnant women were less likely than non-pregnant women to report perceived risks from vaccine-preventable illness (22.8% vs. 34.5%, p < 0.001) and to believe that their doctor thinks they should get vaccines (42.6% vs. 49.7%, p < 0.027). Nearly two-thirds (61%) reported concern about possible vaccine effects on their pregnancy. However, the overwhelming majority (89%) of pregnant women surveyed reported willingness to accept vaccination during pregnancy if recommended by their obstetrician. CONCLUSION: Despite concerns about vaccine safety and a low perceived need for immunization, most pregnant respondents endorse acceptance of vaccination when recommended by their obstetrician. These findings suggest that obstetric providers should maximize opportunities for uptake of appropriate immunizations during pregnancy.

Dextromethorphan as a novel nonopioid adjunctive agent for pain control with medication abortion: A randomized controlled trial.

OBJECTIVES: To evaluate efficacy and satisfaction of dextromethorphan as a non-narcotic adjuvant to current analgesic regimens for medication abortion. STUDY DESIGN: We conducted a randomized, double-blinded, placebo-controlled trial. We randomized eligible participants (N = 156) 1:1 to adjunctively take dextromethorphan (loading dose 60 mg and two subsequent 30 mg doses at 2 and 5 hours after misoprostol administration) or placebo combined with usual-care nonsteroidal anti-inflammatory medications ± opioids for pain. Participants reported pain scores and satisfaction using a secure texting application at 2, 5, 8, and 24 hours after misoprostol administration. Our primary outcome was worst pain score and total analgesic use. RESULTS: Baseline demographics of enrolled participants were similar between randomization arms. Worst pain scores for participants receiving dextromethorphan versus placebo (8.0 vs 7.0, p = 0.06) did not differ. Total milligram usage of ibuprofen (800 mg vs 610 mg, p =.62), acetaminophen (1000 mg vs 1300 mg, p = 0.62), and opioids (10 mg vs 15 mg, p = 0.51) did not differ between the randomization groups. Participants randomized to placebo were significantly more likely to be satisfied with their pain control (91% vs 75%, p = 0.02). CONCLUSION: Dextromethorphan used adjunctively with standard analgesics did not reduce pain associated with medication abortion. Participants who received dextromethorphan reported decreased satisfaction with their pain control. IMPLICATIONS: Dextromethorphan used adjunctively with commonly used analgesic regimens did not reduce medication abortion associated pain. Many participants did not use analgesics as counseled, and nearly 25% used no analgesia during medication abortion.

Twelve Month Outcomes of Pelvic Organ Prolapse Surgery in Patients With Uterovaginal or Posthysterectomy Vaginal Prolapse Enrolled in the Multicenter Pelvic Floor Disorders Registry.

OBJECTIVE: The aim of the study was to compare 12-month subjective and objective outcomes between 3 approaches to apical pelvic organ prolapse (POP) surgery in patients presenting with uterovaginal or posthysterectomy vaginal prolapse enrolled in the Pelvic Floor Disorders Registry for Research. STUDY DESIGN: This was an analysis of a multicenter, prospective registry that collected both patient- and physician-reported data for up to 3 years after conservative (pessary) and surgical treatment for POP. Twelve-month subjective and anatomic outcomes for patients who underwent surgical treatment were extracted from the registry for analysis. Pelvic organ prolapse recurrence was defined as a composite outcome and compared between the 3 apical surgery groups (native tissue repair, sacrocolpopexy, colpocleisis) as well as the 2 reconstructive surgery groups (native tissue repair and sacrocolpopexy). RESULTS: A total of 1,153 women were enrolled in the registry and 777 (67%) opted for surgical treatment, of whom 641 underwent apical repair and were included in this analysis (404 native tissue repair, 187 sacrocolpopexy, and 50 colpocleisis). The overall incidence of recurrence was as follows: subjective 6.5%, anatomic 4.7%, retreatment 7.2%, and composite 13.6%. The incidence of recurrence was not different between the 3 surgical groups. When baseline patient characteristics were controlled for, composite POP recurrence between the native tissue and sacrocolpopexy groups remained statistically nonsignificant. Concurrent perineorrhaphy with any type of apical POP surgery was associated with a lower risk of recurrence (adjusted odds ratio, 0.43; 95% confidence interval, 0.25-0.74; P = 0.002) and prior hysterectomy was associated with a higher risk (adjusted odds ratio, 1.77, 95% confidence interval, 1.04-3.03; P = 0.036). CONCLUSION: Pelvic Floor Disorders Registry for Research participants undergoing native tissue apical POP repair, sacrocolpopexy, and colpocleisis surgery had similar rates of POP recurrence 12 months after surgery.

Incidence and epidemiology of Streptococcus pseudoporcinus in the genital tract.

Streptococcus pseudoporcinus, a beta-hemolytic microorganism first isolated from the female gastrourinary tract in 2006, cross-reacts with serogrouping kits for group B Streptococcus (GBS) and could be misidentified in the laboratory. The epidemiologic characteristics of this species have not been reported previously, but this organism is thought to be rare. Paired vaginal and rectal samples were collected from 663 nonpregnant women enrolled in a phase II clinical vaccine trial of a GBS type III capsular polysaccharide-protein conjugate vaccine, and isolates initially identified as S. pseudoporcinus were collected for further testing. A total of 120 isolates of S. pseudoporcinus were recovered from 36 unique individuals with 5.4% of 663 women having this organism recovered at least once during follow-up. All of these isolates cross-reacted with a commercially available GBS serogrouping kit. Women colonized with isolates confirmed as S. pseudoporcinus by genotypic and phenotypic methodologies were compared to women who were not colonized to determine whether there were any significant factors associated with acquisition of S. pseudoporcinus. Acquisition of S. pseudoporcinus vaginally and/or rectally was 36 per 846.0 women-years of follow-up for an annual incidence of 4 per 100 woman-years of follow-up. Acquisition of S. pseudoporcinus was independently associated with black women, being 30 to 40 years of age, recent Trichomonas vaginalis infection, primary or recurrent genital herpes, having bacterial vaginosis by Nugent criteria, and having had two or more male sexual partners since the last visit. This study suggests that S. pseudoporcinus is not rare, especially among black women, and could be misidentified as GBS.

Mifepristone and misoprostol for early pregnancy failure: a cohort analysis.

OBJECTIVE: We sought to examine outcomes of mifepristone and misoprostol for early pregnancy failure (EPF) treatment in a nonresearch setting. STUDY DESIGN: A protocol was developed for physicians to use mifepristone 200 mg orally and misoprostol 800 µg vaginally for EPF. Success rates were analyzed and an adjusted multivariable regression was used to identify factors predictive of success. RESULTS: Treatment success occurred in 99 (80%; 95% confidence interval, 72-87%) of 123 patients after mifepristone and a single dose of misoprostol and 102 (83%; 95% confidence interval, 75-89%) patients overall. The odds of successful medical treatment were increased in women with a diagnosis of intrauterine embryonic/fetal demise (odds ratio, 3.80) and decreased in women who made additional emergency department visits (odds ratio, 0.12). CONCLUSION: Patients and clinicians may be more likely to intervene surgically with an EPF when a strict study protocol is not being followed.

Prevalence and Predictors of Urinary Incontinence at 1 Year Postpartum.

OBJECTIVES: Postpartum urinary incontinence estimates range from 13% to 47%. Clinical factors associated with incontinence 1 year after first delivery are varied. We assessed the prevalence of and factors associated with urinary incontinence in primiparous women at 12 months postpartum. METHODS: Ancillary analysis of 99 nulliparous women from a prospective cohort study that assessed participants during the first and third trimesters and 12 months postpartum. Our primary outcome was urinary incontinence 12 months postpartum. Women were asked "How often do you experience urine leakage?" and considered to have urinary incontinence if a response other than "never" was reported. We collected vaginal swabs for assessment of matrix metalloproteinase-9 activity, a measure of tissue remodeling. Bivariable and logistic regression analyses were used to compare women with and without postpartum urinary incontinence. RESULTS: Of 99 primiparous women, 55% (n = 54) reported urinary incontinence at 12 months postpartum. Logistic regression demonstrated that urinary incontinence during pregnancy (odds ratio, 34.3; 95% confidence interval, 7.9-149.2) and a decrease in matrix metalloproteinase 9 activity between the first and third trimesters (odds ratio, 19.34; 95% confidence interval, 3.47-107.84) were associated with postpartum urinary incontinence. The sensitivity and specificity of urinary incontinence during pregnancy for predicting postpartum urinary incontinence were 87% and 67%, respectively. The positive and negative predictive values were 76% and 81%, respectively. CONCLUSIONS: Urinary incontinence affected 55% of primiparous women at 12 months postpartum. Urinary incontinence during pregnancy was strongly associated with postpartum incontinence. Importantly, vaginal tissue protease activity during pregnancy represents a possible mechanism for and biomarker of postpartum urinary incontinence.
