Infant feeding for people living with HIV in high resource settings: a multi-disciplinary approach with best practices to maximise risk reduction.

Shared decision making for infant feeding in the context of HIV in high-resourced settings is necessary to acknowledge patient autonomy, meet increasing patient requests and address the changing reality of perinatal HIV care. In low-to middle-income countries (LMIC), where the majority of individuals living with HIV reside, persons with HIV are recommended to breastfeed their infants. In the setting of maternal anti-retroviral therapy (ART) use throughout pregnancy, viral suppression and appropriate neonatal post-exposure prophylaxis (PEP) use, updated information indicates that the risk of HIV transmission through breastmilk may be between 0.3 and 1%. While not endorsing or recommending breastfeeding, the United States' DHHS perinatal guidelines are similarly pivoting, stating that individuals should "receive patient-centred, evidence-based counselling on infant feeding options." Similar statements appear in the British, Canadian, Swiss, European, and Australasian perinatal guidelines. We assembled a multi-disciplinary group at our institution to develop a structured shared decision-making process and protocol for successful implementation of breastfeeding. We recommend early and frequent counselling about infant feeding options, which should include well known benefits of breastfeeding even in the context of HIV and the individual's medical and psychosocial circumstances, with respect and support for patient's autonomy in choosing their infant feeding option.

Women Living with Human Immunodeficiency Virus with Intended and Unintended Pregnancy: Characteristics and Patient Outcomes.

Background: Rates of unintended pregnancy may be higher in women living with human immunodeficiency virus (WLWH) than in the general population, and it is unclear how populations of WLWH with intended and unintended pregnancy differ. We compared baseline characteristics and outcomes between WLWH with intended and unintended pregnancy. Materials and Methods: We conducted a retrospective analysis of WLWH enrolled in a human immunodeficiency virus (HIV) and Pregnancy clinic from 2003 to 2014. Data were analyzed using descriptive statistics, chi-square test, Student's t-test, one-way analysis of variance, and linear and logistic regression analysis. Two-tailed p-value <0.05 was considered significant. The study was approved by the Johns Hopkins University School of Medicine Institutional Review Board. Results: Sixty-nine (27.1%) of 255 women reported an intended pregnancy. Women with intended pregnancy (WWIP) were more likely to be older, White, married, privately insured, and college educated. WWIP were less likely to use tobacco (15.9% vs. 44.2%, p < 0.001), alcohol (2.9% vs. 11.1%, p = 0.041), opiates (0.0% vs. 19.3%, p < 0.001), or cocaine (2.9% vs. 21.0%, p < 0.001) during pregnancy, more likely to disclose their HIV status to the father of the baby by delivery (100.0% vs. 15.8%, p < 0.001), and more likely to receive less effective contraception at delivery (condoms 14.9% vs. 4.8%, p = 0.024; sterilization 11.9% vs. 22.1%, p = 0.028). In multivariate regression analysis, pregnancy intendedness was an important predictor of nondetectable viral load at pregnancy entry but not at delivery. Conclusions: WLWH vary in their baseline characteristics and pregnancy outcomes depending on pregnancy intendedness, highlighting the need to improve pregnancy timing in WLWH and intensify interventions for women with unintended pregnancy.

Understanding clinical outcome measures reported in HIV pregnancy studies involving antiretroviral-naive and antiretroviral-experienced women.

HIV infection is a clinically significant public health disease and contributes to increased risk of maternal and fetal morbidity and mortality. HIV pregnancy studies use outcome measures as metrics to show how people with HIV feel, function, or survive. These endpoints are crucial for tracking the evolution of HIV illness over time, assessing the effectiveness of antiretroviral therapy (ART), and comparing outcomes across studies. Although the need for ideal outcome measures is widely acknowledged, selecting acceptable outcome measures for these HIV pregnancy studies can be challenging. We discuss the many outcome measures that have been implemented over time to assess HIV in pregnancy studies, their benefits, and drawbacks. Finally, we offer suggestions for improving the reporting of outcome measures in HIV in pregnancy studies. Medical professionals can best care for pregnant women living with HIV receiving ART by having a thorough understanding of these outcome metrics.

Special ambulatory gynecologic considerations in the era of coronavirus disease 2019 (COVID-19) and implications for future practice.

The coronavirus disease 2019 pandemic has altered medical practice in unprecedented ways. Although much of the emphasis in obstetrics and gynecology to date has been on the as yet uncertain effects of coronavirus disease 2019 in pregnancy and on changes to surgical management, the pandemic has broad implications for ambulatory gynecologic care. In this article, we review important ambulatory gynecologic topics such as safety and mental health, reproductive life planning, sexually transmitted infections, and routine screening for breast and cervical cancer. For each topic, we review how care may be modified during the pandemic, provide recommendations when possible on how to ensure continued access to comprehensive healthcare at this time, and discuss ways that future practice may change. Social distancing requirements may place patients at higher risk for intimate partner violence and mental health concerns, threaten continued access to contraception and abortion services, affect prepregnancy planning, interrupt routine screening for breast and cervical cancer, increase risk of sexually transmitted infection acquisition and decrease access to treatment, and exacerbate already underlying racial and minority disparities in care and health outcomes. We advocate for increased use of telemedicine services with increased screening for intimate partner violence and depression using validated questionnaires. Appointments for long-acting contraceptive insertions can be prioritized. Easier access to patient-controlled injectable contraception and pharmacist-provided hormonal contraception can be facilitated. Reproductive healthcare access can be ensured through reducing needs for ultrasonography and laboratory testing for certain eligible patients desiring abortion and conducting phone follow-up for medication abortions. Priority for in-person appointments should be given to patients with sexually transmitted infection symptoms, particularly if at risk for complications, while also offering expedited partner therapy. Although routine mammography screening and cervical cancer screening may be safely delayed, we discuss society guideline recommendations for higher-risk populations. There may be an increasing role for patient-collected human papillomavirus self-samples using new cervical cancer screening guidelines that can be expanded considering the pandemic situation. Although the pandemic has strained our healthcare system, it also affords ambulatory clinicians with opportunities to expand care to vulnerable populations in ways that were previously underutilized to improve health equity.

Relationship between vitamin D status and the vaginal microbiome during pregnancy.

OBJECTIVE: Evidence supports an inverse association between vitamin D and bacterial vaginosis (BV) during pregnancy. Furthermore, both the vaginal microbiome and vitamin D status correlate with pregnancy outcome. Women of African ancestry are more likely to experience BV, to be vitamin D deficient, and to have certain pregnancy complications. We investigated the association between vitamin D status and the vaginal microbiome. STUDY DESIGN: Subjects were assigned to a treatment (4400 IU) or a control group (400 IU vitamin D daily), sampled three times during pregnancy, and vaginal 16S rRNA gene taxonomic profiles and plasma 25-hydroxyvitamin D [25(OH)D] concentrations were examined. RESULT: Gestational age and ethnicity were significantly associated with the microbiome. Megasphaera correlated negatively (p = 0.0187) with 25(OH)D among women of African ancestry. Among controls, women of European ancestry exhibited a positive correlation between plasma 25(OH)D and L. crispatus abundance. CONCLUSION: Certain vaginal bacteria are associated with plasma 25(OH)D concentration.

Unexpected High Rates of Persistent Trichomonas vaginalis Infection in a Retrospective Cohort of Treated Pregnant Women.

BACKGROUND: Our primary objective was to determine the rate of persistent Trichomonas infection among pregnant women posttreatment. The secondary objective was to determine if oral multidose metronidazole was associated with fewer cases of persistent Trichomonas compared with single-dose treatment. METHODS: This is a retrospective cohort study of women diagnosed with genital Trichomonas vaginalis from 2008 to 2017. We calculated the rate of persistent Trichomonas by dividing the number of positive Trichomonas tests collected 21 days or longer posttreatment by the total number of women treated and retested. Bivariate analysis was performed to compare the rates of positive tests after single and multidose metronidazole. Multivariate logistic regression was used to evaluate factors associated with persistent infection. RESULTS: Five hundred forty-two women with 565 pregnancies were diagnosed with Trichomonas infection. The majority of subjects were prescribed either single-dose (n = 352) or multidose metronidazole (n = 74). Posttreatment Trichomonas tests were collected 21 days or longer in 326 subjects and 44% (143) were positive. Rates of positive Trichomonas tests among women receiving single-dose and multidose regimens were similar (45% vs. 40%, P = 0.50). Women who had ≥1 pregnancy affected by Trichomonas infection were more likely to have a positive test posttreatment (adjusted odds ratio, 20.1; 95% confidence interval, 1.9-215.3). Obese women were less likely to have a positive test posttreatment (adjusted odds ratio, 0.3; 95% confidence interval, 0.1-0.9). CONCLUSIONS: Given high rates of positive Trichomonas tests and increased detection with nucleic acid amplification tests (NAATs), all pregnant women should be retested with NAATs approximately 3 weeks posttreatment. Further studies are needed to determine the most effective treatment of Trichomonas infection in pregnant women.

The Impact of Delivery in a Rural County on a Cohort of Women Living with HIV Infection and Their Infants.

PURPOSE: We sought to determine if infants born in rural counties had an increased risk of contracting HIV. METHODS: Data were obtained from the South Carolina Department of Health and Environmental Control for all women living with HIV delivering from 2004 to 2014. In this retrospective cohort study, maternal and neonatal outcomes from urban and rural counties were compared. Binomial statistical analyses were conducted using Wilcoxon Rank Sum Tests, χ2 or Fisher's exact tests. Logistic regression analyses were performed to evaluate factors associated with perinatal HIV infection. FINDINGS: Six hundred and sixty-six women living with HIV had 868 pregnancies and delivered 885 infants; 17% (148) were born in rural counties. Eleven infants (1.2%) were diagnosed with perinatal HIV infection. The proportion of women taking antenatal antiretroviral therapy (ART) was similar between rural and urban counties (84% vs 87%; P = .3), but women in urban counties were more likely to have an HIV RNA viral load <40 copies/mL before delivery (32% vs 42%; P = .05). Factors associated with perinatal HIV infection were intra- and postpartum maternal HIV diagnosis (aOR 61.4 [95% CI: 6.7-562.5]; P < .001), parenteral drug use (aOR 7.5 [1.6-34.7]; P = .01), and preterm birth (<37 weeks gestation) (aOR 4.6 [1.2-17.8]; P = .3). CONCLUSIONS: Delivery in a rural county was not associated with an increased risk of perinatal HIV transmission. Women delivering in rural counties taking ART were less likely to have HIV viral suppression, which is a risk factor for perinatal HIV infection.

The Effect of HIV-Centered Obstetric Care on Perinatal Outcomes Among a Cohort of Women Living With HIV.

BACKGROUND: Elimination of perinatal transmission is possible but limited by missed care opportunities. Our objective was to investigate the effects of HIV-centered obstetric care (HCC) on missed care opportunities and perinatal HIV transmission in 2 obstetric cohorts at our institution from 2000 to 2014. METHODS: This was a retrospective cohort study of HIV-exposed mother-infant pairs delivering from 2000 to 2014, analyzed according to SQUIRE 2.0 (Standards for Quality Improvement Reporting Excellence) guidelines. Before 2009, women received care in high-risk obstetric care (HRC); subsequently, an HCC service was established. Women who received HRC vs HCC obstetric care were compared to determine differences in maternal and neonatal outcomes. Continuous variables were compared with Student t test and Wilcoxon rank sum tests. Categorical variables were compared using χ test and Fisher exact test. Logistic regression analyses were performed to determine factors associated with outcomes of interest. RESULTS: Over 14 years, 161 women delivered 217 HIV-exposed infants; 78 (36%) women received HCC. Two perinatal HIV transmissions (1.5%) occurred in HRC group compared with none in the HCC group (P = 0.3). Women in HCC were more likely to have HIV RNA viral load <1000 copies per milliliter at delivery (12% vs 26%, P = 0.02), have a contraception plan before delivery (93% vs 60%, P < 0.001), return for postpartum evaluation (80% vs 63%, P = 0.01), and have undetectable HIV viral load postpartum (50 copies per milliliter vs 2067, P < 0.0001). CONCLUSIONS: HCC can potentially reduce the risk of perinatal HIV transmission by improving maternal virologic control during pregnancy and postpartum and increasing postpartum contraceptive use.

The induction of CD80 and apoptosis on B cells and CD40L in CD4+ T cells in response to seasonal influenza vaccination distinguishes responders versus non-responders in healthy controls and aviremic ART-treated HIV-infected individuals.

BACKGROUND: Studies have shown that HIV infection is associated with an impaired influenza vaccine response. We examined the role of cellular phenotypes and function in influenza vaccine responsiveness in healthy controls and aviremic HIV-infected subjects on antiretroviral treatment (ART). METHODS: 16 healthy controls and 26 ART+ aviremic HIV+ subjects were enrolled in the current study. Blood was collected at pre-vaccination (D0), and on days 7-10 (D7) and 14-21 (D14) following the 2013-2014 seasonal influenza vaccine administrations. Subjects were classified as responders if neutralizing titers against H1N1 virus increased ⩾4-fold at D14 compared to D0. A serial analysis of B and CD4+ T cell frequencies and activation was performed on D0 and D7 by flow cytometry. RESULTS: 9 of 26 (34.6%) HIV-infected individuals and 7 of 16 (43.8%) healthy controls were classified as responders to influenza vaccines. Total B cell apoptosis (annexin V) was increased on D7 post-vaccination in non-responders but not in responders among both controls and HIV+ subjects. Surface CD80 expression on memory B cells and intracellular CD40L expression on memory CD4+ T cells were induced on D7 in responders of controls but not in non-responders. The CD80 and CD40L induction was not demonstrable in HIV-infected subjects regardless of responders and non-responders. Memory CD4+ T cell cycling tended to increase on D7 in the four study groups but did not achieve significance. All the other parameters were indistinguishable between responders and non-responders, regardless of HIV-infection status. CONCLUSION: The perturbation of activation and apoptotic induction on B cells or CD4+ T cells after seasonal influenza vaccination in non-responders and HIV-infected subjects may help understand the mechanism of impaired vaccine responsiveness.

Non-albicans Candida Vulvovaginitis: Treatment Experience at a Tertiary Care Vaginitis Center.

OBJECTIVES: The aims of this study are to analyze a cohort of women with vulvovaginal symptoms and positive cultures for non-albicans Candida (NAC) to determine whether yeast was responsible for their symptoms and to evaluate the mycological effectiveness of various regimens. METHODS: This observational study was performed from retrospective chart review of patients with positive NAC cultures between April 1, 2008, and January 31, 2011, at a tertiary care vaginitis center. Patient intake demographics were entered into a database. Follow-up visits were analyzed for data about patient treatments and outcomes. Patients were considered a clinical cure if their symptoms were significantly improved and mycologic cure (MC) if later yeast cultures were negative. If clinical symptoms improved at the same time as MC, the isolate was considered the proximate cause for the symptoms. RESULTS: One hundred eight patients meeting entry criteria were analyzed. Boric acid was effective at obtaining MC in 32 (78%) of 41 patients with C. glabrata, 3 of 3 patients with C. tropicalis, and 3 of 3 patients with C. lusitaniae. Fluconazole was effective as initial treatment for 3 (60%) of 5 patients with C. glabrata and 13 (81%) of 16 patients with C. parapsilosis. In 52.7% of C. glabrata, 66.7% of C. parapsilosis, and 57.1% of C. tropicalis cases, effective antifungal therapy led to symptom improvement. CONCLUSIONS: In a tertiary care vaginitis center, NAC, when isolated on culture, caused clinically significant infections in approximately half of symptomatic patients. A majority of infections can be effectively treated with boric acid or fluconazole regardless of the non-albicans Candida species.

New Perspectives on the Normal Vagina and Noninfectious Causes of Discharge.

An understanding of how the vaginal flora is influenced by hormonal status is crucial in distinguishing normal from abnormal secretions. New studies exploring the vaginal microbiome with culture-independent techniques have led to the discovery of previously uncultivable bacteria on a species level, and have contributed to a better understanding of disease processes including bacterial vaginosis. It is important to note that not all vaginal discharge is abnormal or infectious in etiology, but a thorough evaluation will help reassure both the patient and the provider.

Recurrent vulvovaginitis.

Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV.

Outcomes of effective transmission of electronic prenatal records from the office to the hospital.

OBJECTIVE: To investigate the outcomes associated with improved transmission of prenatal test results between the outpatient and inpatient obstetric setting after implementation of an electronic prenatal record system. METHODS: Admission paper charts of patients admitted to our labor and delivery unit were reviewed before and after implementation of an electronic prenatal record system. The availability of maternal hepatitis B and human immunodeficiency virus (HIV) serology on admission, the occurrence of repeat hepatitis B surface antigen and rapid HIV blood testing, and the occurrence of hepatitis B immunoglobulin administration to the newborns of mothers without available hepatitis B serology was recorded. Fisher's exact tests were performed to determine differences in availability of prenatal test results, the occurrence of repeat blood testing, and the occurrence of immunoglobulin administration before and after implementation. RESULTS: A total of 460 admission charts were reviewed, 229 preimplementation and 231 postimplementation. Of the preimplementation charts, 78.2% contained maternal hepatitis B and HIV serology results, whereas all postimplementation charts contained such results (P<.001). Although repeat hepatitis B surface antigen testing was performed in 3.1% of patients preimplementation, no patients required repeat testing postimplementation (P=.007). Similarly, rapid HIV blood testing was performed in 3.5% of patients preimplementation, but no patients required repeat testing postimplementation (P=.003). Increased availability of testing results prevented unnecessary administration of hepatitis B immunoglobulin postimplementation. CONCLUSION: Implementation of an electronic perinatal record system was associated with improved transmission of prenatal test results between the outpatient and inpatient obstetric setting and a decreased rate of unnecessary maternal testing and newborn interventions. LEVEL OF EVIDENCE: III.

Vaginorectal Streptococcus porcinus in pregnancy: an emerging pathogen?

OBJECTIVE: Streptococcus porcinus has previously been isolated from the genitourinary tract of reproductive-aged women. However, very little is known about the pathogenicity of this microorganism in pregnancy. The study aimed to report pregnancies complicated by vaginorectal S. porcinus and associated adverse outcomes. MATERIALS AND METHODS: We present 2 patients with 3 pregnancies complicated by vaginorectal S. porcinus and preterm cervical change. RESULTS: The first patient lost a twin pregnancy to previable preterm rupture of membranes. During her subsequent pregnancy, again positive for S. porcinus, cervical shortening prompted antibiotic treatment and cerclage. The second patient delivered preterm despite cerclage placed for sonographic indications. CONCLUSIONS: Our cases suggest that S. porcinus may contribute to the pathogenesis of preterm rupture of membranes and cervical insufficiency.
