RESUMO
BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in pregnancy contribute to adverse perinatal outcomes. We identified predictors of CT and/or NG infection among pregnant Kenyan women. METHODS: Women without HIV were enrolled at 2 antenatal clinics in Western Kenya. Both CT and NG were assessed using endocervical samples for nucleic acid amplification tests. Poisson regression models were used to evaluate potential CT/NG risk factors. Classification and regression trees were generated to evaluate the joint effects of predictors. RESULTS: Overall, 1276 women had both CT and NG assessments. Women enrolled at a median of 26 weeks' gestation (interquartile range, 22-31 weeks), median age was 22 years (interquartile range, 19-27 years), and 78% were married. In total, 98 (7.7%) tested positive for CT/NG: 70 (5.5%) for CT and 32 (2.5%) for NG, 4 of whom (0.3%) had coinfections. Two-thirds (66%) of CT/NG cases were asymptomatic and would have been missed with only syndromic management. Risk factors of CT/NG included age <22 years, crowded living conditions, being unmarried, being in partnerships for <1 year, abnormal vaginal discharge, sexually transmitted infection history, and Trichomonas vaginalis diagnosis ( P < 0.1). Classification and regression tree analyses identified unmarried women <22 years in relationships for <1 year as 6.1 times more likely to have CT/NG compared with women without these characteristics (26% vs. 6%, adjusted prevalence ratio = 6.1, 95% confidence interval = 3.55-10.39, P < 0.001). CONCLUSIONS: Chlamydia trachomatis / Neisseria gonorrhoeae was frequently asymptomatic and common among young unmarried women in newer partnerships in this cohort. Integrating CT/NG testing into routine antenatal care may be beneficial, especially for young women in Kenya.

BACKGROUND: Pregnancy and human immunodeficiency virus (HIV) may influence tuberculosis infection detection using interferon (IFN)-γ release assay (QFT-Plus; Qiagen) and tuberculin skin test (TST). METHODS: Participants in Western Kenya underwent QFT-Plus and TST in pregnancy, 6 weeks postpartum (6wkPP) and 12 months postpartum (12moPP). RESULTS: 400 participants (200 with HIV [WHIV], 200 HIV-negative) enrolled during pregnancy (median 28 weeks' gestation [interquartile range, 24-30]). QFT-Plus positivity prevalence was higher than TST in pregnancy (32.5% vs 11.6%) and through 12moPP (6wkPP, 30.9% for QFT-Plus vs 18.0% for TST; 12moPP, 29.5% vs 17.1%; all P < .001), driven primarily by QFT-Plus-positive/TST-negative discordance among HIV-negative women. Tuberculosis infection test conversion incidence was 28.4/100 person-years (PY) and higher in WHIV than HIV-negative women (35.5 vs 20.9/100 PY; hazard ratio, 1.73 [95% confidence interval, 1.04-2.88]), mostly owing to early postpartum TST conversion among WHIV. Among QFT-Plus-positive participants in pregnancy, Mycobacterium tuberculosis (Mtb)-specific IFN-γ responses were dynamic through 12moPP and lower among WHIV than HIV-negative women with tuberculosis infection at all time points. CONCLUSIONS: QFT-Plus had higher diagnostic yield than TST in peripartum women. Peripartum QFT-Plus positivity was stable and less influenced by HIV than TST. Mtb-specific IFN-γ responses were dynamic and lower among WHIV. Tuberculosis infection test conversion incidence was high between pregnancy and early postpartum, potentially owing to postpartum immune recovery.

HIV-exposed uninfected (HEU) children and adolescents are at higher risk of poor outcomes compared to HIV-unexposed children (HUU). In program settings, it is critical to understand how to identify HEU for screening services. We describe our experience identifying HEU for a neurodevelopment and mental health screening study. We recruited mothers living with HIV (MLHIV) and mothers not living with HIV (MNHIV) and enrolled their HEU or HUU children. We summarise the reasons for ineligibility and recruitment challenges. Among MLHIV, their child's ineligibility increased with age: 12%, 27%, 50% and 80% in age groups 3-6, 7-10, 11-14, and 15-18, respectively (p < 0.001). Reasons for ineligibility were unknown maternal HIV status during pregnancy or breastfeeding (30%), and maternal disinterest due to fear of inadvertent disclosure of their HIV status to older youth. Recruiting older HEU youth is challenging. Maternal concerns of self-disclosing their HIV status impedes identification of older HEU.

Cumulative 24-month Mycobacterium tuberculosis infection incidence (measured primarily by tuberculin skin test [TST]) was high among human immunodeficiency virus exposed but uninfected infants (8.7 [95% confidence interval, 6.3-11.9] per 100 person-years). Trend for decreased TST positivity among infants at trial end (12 months postenrollment) randomized to isoniazid at 6 weeks of age was not sustained through observational follow-up to 24 months of age.

Depression among pregnant women living with HIV (WLWH) in sub-Saharan Africa leads to poor pregnancy and HIV outcomes. This cross-sectional analysis utilized enrollment data from a randomized trial (Mobile WAChX, NCT02400671) in six Kenyan public maternal and child health clinics. Depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9), stigma with the Stigma Scale for Chronic Illness, and intimate partner violence (IPV) with the Abuse Assessment Screen. Correlates of moderate-to-severe depressive symptoms ("depression", PHQ-9 score ≥10) were assessed using generalized estimating equation models clustered by facility. Among 824 pregnant WLWH, 9% had depression; these women had more recent HIV diagnosis than those without depression (median 0.4 vs. 2.0 years since diagnosis, p = .008). Depression was associated with HIV-related stigma (adjusted Prevalence Ratio [aPR]:2.36, p = .025), IPV (aPR:2.93, p = .002), and lower social support score (aPR:0.99, p = .023). Using population-attributable risk percent to estimate contributors to maternal depression, 81% were attributable to stigma (27%), recent diagnosis (24%), and IPV (20%). Integrating depression screening and treatment in prevention of mother-to-child HIV transmission programs may be beneficial, particularly in women recently diagnosed or reporting stigma and IPV.

BACKGROUND: Identifying predictors of preterm birth (PTB) in high-burden regions is important as PTB is the leading cause of global child mortality. METHODS: This analysis was nested in a longitudinal study of human immunodeficiency virus (HIV) incidence in Kenya. HIV-seronegative women enrolled in pregnancy had nucleic acid amplification tests (chlamydia and gonorrhea), rapid plasma reagin (syphilis), wet mount microscopy (Trichomonas and yeast), and Gram stain (bacterial vaginosis); sexually transmitted infection (STI) treatment was provided. PTB predictors were determined using log-binomial regression. RESULTS: Among 1244 mothers of liveborn infants, median gestational age at enrollment was 26 weeks (IQR, 22-31), and at delivery was 39.1 weeks (IQR, 37.1-40.9). PTB occurred in 302 women (24.3%). Chlamydia was associated with a 1.59-fold (P = .006), gonorrhea a 1.62-fold (P = .04), and incident HIV a 2.08-fold (P = .02) increased PTB prevalence. Vaginal discharge and cervical inflammation were associated with PTB, as were age ≤21 (prevalence ratio [PR] = 1.39, P = .001) and any STI (PR = 1.47, P = .001). Associations with chlamydia and incident HIV remained in multivariable models. CONCLUSIONS: STIs and incident HIV in pregnancy predicted PTB despite treatment, suggesting the need for earlier treatment and interventions to decrease genital inflammation.

BACKGROUND: Human immunodeficiency virus (HIV)-exposed uninfected (HEU) infants in endemic settings are at high risk of tuberculosis (TB). For infants, progression from primary Mycobacterium tuberculosis (Mtb) infection to TB disease can be rapid. We assessed whether isoniazid (INH) prevents primary Mtb infection. METHODS: We conducted a randomized nonblinded controlled trial enrolling HEU infants 6 weeks of age without known TB exposure in Kenya. Participants were randomized (1:1) to 12 months of daily INH (10 mg/kg) vs no INH. Primary endpoint was Mtb infection at end of 12 months, assessed by interferon-γ release assay (QuantiFERON-TB Gold Plus) and/or tuberculin skin test (TST, added 6 months after first participant exit). RESULTS: Between 15 August 2016 and 6 June 2018, 416 infants were screened, with 300 (72%) randomized to INH or no INH (150 per arm); 2 were excluded due to HIV infection. Among 298 randomized HEU infants, 12-month retention was 96.3% (287/298), and 88.9% (265/298) had primary outcome data. Mtb infection prevalence at 12-month follow-up was 10.6% (28/265); 7.6% (10/132) in the INH arm and 13.5% (18/133) in the no INH arm (7.0 vs 13.4 per 100 person-years; hazard ratio, 0.53 [95% confidence interval {CI}, .24-1.14]; Pâ =â .11]), and driven primarily by TST positivity (8.6% [8/93] in INH and 18.1% [17/94] in no INH; relative risk, 0.48 [95% CI, .22-1.05]; Pâ =â .07). Frequency of severe adverse events was similar between arms (INH, 14.0% [21/150] vs no INH, 10.7% [16/150]; Pâ =â .38), with no INH-related adverse events. CONCLUSIONS: Further studies evaluating TB preventive therapy to prevent or delay primary Mtb infection in HEU and other high-risk infants are warranted. CLINICAL TRIALS REGISTRATION: NCT02613169.

BACKGROUND: Pregnant and postpartum women living with HIV (WLWH) need support for HIV and maternal child health (MCH) care, which could be provided using short message service (SMS). METHODS AND FINDINGS: We compared 2-way (interactive) and 1-way SMS messaging to no SMS in a 3-arm randomized trial in 6 MCH clinics in Kenya. Messages were developed using the Health Belief Model and Social Cognitive Theory; HIV messages were integrated into an existing MCH SMS platform. Intervention participants received visit reminders and prespecified weekly SMS on antiretroviral therapy (ART) adherence and MCH, tailored to their characteristics and timing. Two-way participants could message nurses as needed. Clinic attendance, viral load (VL), and infant HIV results were abstracted from program records. Primary outcomes were viral nonsuppression (VL ≥1,000 c/ml), on-time clinic attendance, loss to follow-up from clinical care, and infant HIV-free survival. Among 824 pregnant women randomized between November 2015 and May 2017, median age was 27 years, gestational age was 24.3 weeks, and time since initiation of ART was 1.0 year. During follow-up to 2 years postpartum, 9.8% of 3,150 VL assessments and 19.6% of women were ever nonsuppressed, with no significant difference in 1-way versus control (11.2% versus 9.6%, adjusted risk ratio (aRR) 1.02 [95% confidence interval (CI) 0.67 to 1.54], p = 0.94) or 2-way versus control (8.5% versus 9.6%, aRR 0.80 [95% CI 0.52 to 1.23], p = 0.31). Median ART adherence and incident ART resistance did not significantly differ by arm. Overall, 88.9% (95% CI 76.5 to 95.7) of visits were on time, with no significant differences between arms (88.2% in control versus 88.6% in 1-way and 88.8% in 2-way). Incidence of infant HIV or death was 3.01/100 person-years (py), with no significant difference between arms; risk of infant HIV infection was 0.94%. Time to postpartum contraception was significantly shorter in the 2-way arm than control. Study limitations include limited ability to detect improvement due to high viral suppression and visit attendance and imperfect synchronization of SMS reminders to clinic visits. CONCLUSIONS: Integrated HIV/MCH messaging did not improve HIV outcomes but was associated with improved initiation of postpartum contraception. In programs where most women are virally suppressed, targeted SMS informed by VL data may improve effectiveness. Rigorous evaluation remains important to optimize mobile health (mHealth) interventions. TRIAL REGISTRATION: ClinicalTrials.gov number NCT02400671.

BACKGROUND: People living with HIV (PLHIV) who reside in high tuberculosis burden settings remain at risk for tuberculosis disease despite treatment with anti-retroviral therapy and isoniazid preventive therapy (IPT). The performance of the World Health Organization (WHO) symptom screen for tuberculosis in PLHIV receiving anti-retroviral therapy is sub-optimal and alternative screening strategies are needed. METHODS: We enrolled HIV-positive adults into a prospective study in western Kenya. Individuals who were IPT-naïve or had completed IPT > 6 months prior to enrollment were eligible. We evaluated tuberculosis prevalence overall and by IPT status. We assessed the accuracy of the WHO symptom screen, GeneXpert MTB/RIF (Xpert), and candidate biomarkers including C-reactive protein (CRP), hemoglobin, erythrocyte sedimentation rate (ESR), and monocyte-to-lymphocyte ratio for identifying pulmonary tuberculosis. Some participants were evaluated at 6 months post-enrollment for tuberculosis. RESULTS: The study included 383 PLHIV, of whom > 99% were on antiretrovirals and 88% had received IPT, completed a median of 1.1 years (IQR 0.8-1.55) prior to enrollment. The prevalence of pulmonary tuberculosis at enrollment was 1.3% (n = 5, 95% CI 0.4-3.0%): 4.3% (0.5-14.5%) among IPT-naïve and 0.9% (0.2-2.6%) among IPT-treated participants. The sensitivity of the WHO symptom screen was 0% (0-52%) and specificity 87% (83-90%). Xpert and candidate biomarkers had poor to moderate sensitivity; the most accurate biomarker was CRP ≥ 3.3 mg/L (sensitivity 80% (28-100) and specificity 72% (67-77)). Six months after enrollment, the incidence rate of pulmonary tuberculosis following IPT completion was 0.84 per 100 person-years (95% CI, 0.31-2.23). CONCLUSIONS: In Kenyan PLHIV treated with IPT, tuberculosis prevalence was low at a median of 1.4 years after IPT completion. WHO symptoms screening, Xpert, and candidate biomarkers were insensitive for identifying pulmonary tuberculosis in antiretroviral-treated PLHIV.

OBJECTIVES: Recent studies have identified vaginal bacterial taxa associated with increased HIV risk. A possible mechanism to explain these results is that individual taxa differentially promote cervicovaginal inflammation. This study aimed to explore relationships between concentrations of bacteria previously linked to HIV acquisition and vaginal concentrations of proinflammatory cytokines and chemokines. METHODS: In this cross-sectional analysis, concentrations of 17 bacterial taxa and four proinflammatory cytokines (interleukin (IL)-1ß, IL-6, IL-10 and tumour necrosis factor alpha (TNFα)) and two proinflammatory chemokines (IL-8 and interferon gamma-induced protein 10) were measured in vaginal swabs collected from 80 HIV-uninfected women. Cytokine and chemokine concentrations were compared between women with bacterial concentrations above or below the lower limit of detection as determined by quantitative PCR for each taxon. Principal component analysis was used to create a summary score for closely correlated bacteria, and linear regression analysis was used to evaluate associations between this score and increasing concentrations of TNFα and IL-1ß. RESULTS: Detection of Dialister micraerophilus (p=0.01), Eggerthella sp type 1 (p=0.05) or Mycoplasma hominis (p=0.03) was associated with higher TNFα concentrations, and detection of D. micraerophilus (p<0.01), Eggerthella sp type 1 (p=0.04), M. hominis (p=0.02) or Parvimonas sp type 2 (p=0.05) was associated with significantly higher IL-1ß concentrations. Seven bacterial taxa (D. micraerophilus, Eggerthella sp type 1, Gemella asaccharolytica, Sneathia sp, Megasphaera sp, M. hominis and Parvimonas sp type 2) were found to be highly correlated by principal component analysis (eigenvalue 5.24, explaining 74.92% of variability). Linear regression analysis demonstrated associations between this principal component and concentrations of TNFα (ß=0.55, 95% CI 0.01 to 1.08; p=0.048) and IL-1ß (ß=0.96, 95% CI 0.19 to 1.74; p=0.016). CONCLUSIONS: This study provides evidence that several highly correlated vaginal bacterial taxa may influence vaginal cytokine and chemokine concentrations. These results suggest a mechanism where the presence of specific bacterial taxa could influence HIV susceptibility by increasing vaginal inflammation.

OBJECTIVES: We evaluated the relationship of sexually transmitted infections (STIs) and genital infections during pregnancy and subsequent risk for infant mortality and stillbirth. METHODS: This was a nested longitudinal analysis using data from a study of peripartum HIV acquisition in Kenya. In the parent study, HIV-uninfected women were enrolled during pregnancy and followed until 9â months postpartum. For this analysis, women who tested positive for HIV at any point, had a non-singleton pregnancy or a spontaneous abortion <20 weeks were excluded. At enrolment, laboratory methods were used to screen for bacterial vaginosis (BV), vaginal yeast, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV). Syphilis was diagnosed using rapid plasma reagin testing and genital ulcer disease (GUD) identified by clinical examination. Treatment of laboratory-confirmed STIs and syndromic management was provided per Kenyan national guidelines. Predictors of stillbirth and infant mortality were determined using logistic regression and Cox proportional hazards models. RESULTS: Overall, among 1221 women, 55% had STIs or genital infections detected: vaginal yeast (25%), BV (22%), TV (6%), CT (5%), NG (2%) and syphilis (1%). Among women with STIs/genital infections (n=592), 34% had symptoms. Overall, 19/1221 (2%) women experienced stillbirths. Among 1202 live births, 34 infant deaths occurred (incidence 4.0 deaths per 100 person-years, 95% CI 2.8 to 5.5). After adjustment for maternal age, education and study site, stillbirth was associated with maternal GUD (adjusted OR=9.19, 95% CI1.91 to 44.35, p=0.006). Maternal NG was associated with infant mortality (adjusted HR=3.83, 95% CI1.16 to 12.68, p=0.028); there was some evidence that maternal CT was associated with infant mortality. Stillbirth or infant mortality were not associated with other genital infections. CONCLUSIONS: STIs and genital infections were common, frequently asymptomatic and some associated with stillbirth or infant mortality. Expediting diagnosis and treatment of STIs in pregnancy may improve infant outcomes.

Objectives. To assess the effect of 2-way short message service (SMS) with a nurse on postpartum contraceptive use among individual women and couples. Methods. From 2016 to 2017, we conducted a randomized controlled trial at 2 public hospitals in western Kenya. We assigned eligible pregnant women to receive 2-way SMS with a nurse or no SMS, with the option to include male partners. We delivered automated family planning-focused SMS messages weekly until 6 months postpartum. Women and men receiving SMS could interact with nurses via SMS. In intention-to-treat analysis, we compared highly effective contraceptive (HEC) use at 6 months postpartum between groups using the χ2 test. We used Poisson regression in adjusted analysis. Results. We randomized 260 women to 2-way SMS or control, and we enrolled 103 male partners. At 6 months postpartum, 69.9% women receiving SMS reported HEC use, compared with 57.4% in control (relative risk = 1.22; 95% confidence interval [CI] = 1.01, 1.47; P = .04). In analysis adjusted for baseline demographic differences, the adjusted relative risk for HEC use in the SMS group was 1.26 (95% CI = 1.04, 1.52; P = .02). Conclusions. Two-way SMS with a nurse, including optional male participation, increased postpartum contraceptive use. Trial Registration. ClinicalTrials.gov; identifier: NCT02781714.

BACKGROUND: Short message service (SMS) presents an opportunity to expand the reach of care and improve reproductive health outcomes. SMS could increase family planning (FP) use through education, support and demand generation. The purpose of this analysis is to determine the perspectives of potential FP users to inform design of SMS. METHODS: We conducted focus group discussions (FGD) with HIV-infected women and in-depth interviews (IDI) with male partners and health care workers (HCW) at urban and rural clinics in Kenya to design SMS content for a randomized controlled trial. RESULTS: Women and men indicated SMS could be used as a tool to discuss FP with their partners, and help decrease misconceptions about FP. Women stated SMS could make them more comfortable discussing sensitive topics with HCWs compared to in-person discussions. However, some women expressed concerns about FP SMS particularly if they used FP covertly or feared partner disapproval of FP use. These findings were common among women who had not disclosed their status. Providers viewed SMS as an important tool for tracking patients and clinical triage in conjunction with routine clinical visits. CONCLUSION: Our findings suggest that SMS has the potential to facilitate FP education, counselling, and interaction with HCWs around FP.

BACKGROUND: Involving male partners in family planning (FP) education and counseling may improve FP utilization and help meet couples' reproductive health needs in the postpartum period. We aimed to explore Kenyan men's and women's perspectives on an interactive short message service (SMS) approach to support postpartum FP decision-making, and inform intervention content for a randomized controlled trial (RCT). METHODS: We conducted four focus group discussions (FGD) among men (n = 35) and two among pregnant/postpartum women (n = 15) in western Kenya. Female participants were recruited at antenatal clinics; male participants were referred by antenatal attendees. FGDs included participant critique of pilot theory-based SMS messages. FGD transcripts were coded by two investigators and analyzed using an iterative, modified grounded theory approach. These data informed the intervention and RCT design, in which women had the option to refer male partners for trial enrollment. RESULTS: Men strongly desired inclusion in FP programs, and frequently discussed negative relationship consequences of women's covert contraceptive use. Female and male participants voiced a variety of concerns about contraceptive side effects and potential harms, which were central to narratives of community influence on personal contraceptive choices. Most participants felt that receiving FP-focused SMS and including men would be beneficial. They perceived that SMS dialogue with a nurse about FP could reduce misperceptions and may stimulate communication within couples, thereby improving contraceptive access and continuation. Shared decision-making around FP within couple relationships, in consultation with clinicians, was highly valued. CONCLUSIONS: Health concerns about FP and limited couple communication are perceived contributors to postpartum unmet contraceptive need. With women's consent, the inclusion of male partners in FP services, and specifically in an mHealth SMS intervention, is acceptable and desired. Receiving SMS may trigger communication about postpartum FP within couples. SMS content should address contraceptive knowledge gaps, anticipated side effects and FP misperceptions, and allow for real-time method choice assistance.

BACKGROUND: Unmet need for contraception is high during the postpartum period, increasing the risk of unintended subsequent pregnancy. We developed a client facing mobile phone-based family planning (FP) decision aid and assessed acceptability, feasibility, and utility of the tool among health care providers and postpartum women. METHODS: Semi-structured in-depth interviews (IDIs) were conducted among postpartum women (n = 25) and FP providers (n = 17) at 4 Kenyan maternal and child health clinics, 2 in the Nyanza region (Kisumu and Siaya Counties) and 2 in Nairobi. Stratified purposive sampling was used to enroll postpartum women and FP providers. Data were analyzed using an inductive content analysis approach by 3 independent coders, with consensual validation. RESULTS: FP providers stated that the Interactive Mobile Application for Contraceptive Choice (iMACC) tool contained the necessary information about contraceptive methods for postpartum women and believed that it would be a useful tool to help women make informed, voluntary decisions. Most women valued the decision aid content, and described it as being useful in helping to dispel myths and misconceptions, setting realistic expectations about potential side effects and maintaining confidentiality. Both women and providers expressed concerns about literacy and lack of familiarity with smart phones or tablets and suggested inclusion of interactive multimedia such as audio or videos to optimize the effectiveness of the tool. CONCLUSIONS: The iMACC decision aid was perceived to be an acceptable tool to deliver client-centered FP counseling by both women and providers. Counseling tools that can support FP providers to help postpartum women make informed and individualized FP decisions in resource-limited settings may help improve FP counseling and contraceptive use in the postpartum period.

There is growing evidence that mobile health (mHealth) approaches including short messaging service (SMS) can improve antiretroviral therapy (ART) adherence, but consensus is lacking regarding communication of HIV-related information. Most interventions to date have delivered SMS that do not overtly refer to HIV or ART in order to avoid risk of status disclosure. In formative work for an ongoing randomized controlled trial (RCT) evaluating one-way and two-way educational SMS for prevention of mother-to-child-transmission (PMTCT) adherence in Kenya, we conducted 10 focus group discussions (FGDs) with 87 HIV-infected peripartum women to determine desirability and preferred terminology of HIV-related content. SMS for the RCT were developed based on FGD findings. Roughly half of FGD participants supported receiving SMS containing overtly HIV-related terms, such as "HIV" and "medication", citing desire for detailed educational messages about ART and PMTCT. Those opposed to overt content expressed concerns about confidentiality. Many participants argued that acceptability of HIV-related content depended on the recipient's disclosure status and others' access to her phone. Based on these findings, both covert and overt SMS were developed for the RCT and participants who owned their phone or had disclosed their HIV status to anyone with access to their phone were able to choose one of three options: (1) covert SMS only, (2) overt SMS only in response to HIV-related questions from the participant, (3) overt SMS routinely, initiated by the study. Of the 825 participants in the RCT, 94% were eligible to receive overt SMS. Of these, 66% opted to receive routine overt SMS and 10% to receive participant-initiated overt SMS. These findings show there may be interest in overt HIV-related information by SMS when risk of status disclosure is low, and support use of messaging strategies that allows participant choice in HIV-related content while protecting against undesired disclosure.

Background: A human immunodeficiency virus (HIV) risk assessment tool for pregnant women could identify women who would most benefit from preexposure prophylaxis (PrEP) while minimizing unnecessary PrEP exposure. Methods: Data from a prospective study of incident HIV among pregnant/postpartum women in Kenya were randomly divided into derivation (n = 654) and validation (n = 650) cohorts. A risk score was derived using multivariate Cox proportional hazards models and standard clinical prediction rules. Ability of the tool to predict maternal HIV acquisition was assessed using the area under the curve (AUC) and Brier score. Results: The final risk score included the following predictors: having a male partner with unknown HIV status, number of lifetime sexual partners, syphilis, bacterial vaginosis (BV), and vaginal candidiasis. In the derivation cohort, AUC was 0.84 (95% confidence interval [CI], .72-.95) and each point increment in score was associated with a 52% (hazard ratio [HR], 1.52 [95% CI, 1.32-1.76]; P < .001) increase in HIV risk; the Brier score was 0.11. In the validation cohort, the score had similar AUC, Brier score, and estimated HRs. A simplified score that excluded BV and candidiasis yielded an AUC of 0.76 (95% CI, .67-.85); HIV incidence was higher among women with risk scores >6 than with scores ≤6 (7.3 vs 1.1 per 100 person-years, respectively; P < .001). Women with simplified scores >6 accounted for 16% of the population but 56% of HIV acquisitions. Conclusions: A combination of indicators routinely assessed in antenatal clinics was predictive of HIV risk and could be used to prioritize pregnant women for PrEP.

OBJECTIVE: Trichomonas vaginalis is the world's most common curable STI and has implications for reproductive health in women. We determined incidence and correlates of T. vaginalis in an HIV-uninfected peripartum cohort. METHODS: Women participating in a prospective study of peripartum HIV acquisition in Western Kenya were enrolled during pregnancy and followed until 9â months post partum. T. vaginalis was assessed every 1-3â months using wet mount microscopy. Correlates of incident T. vaginalis were determined using Cox proportional hazards models. RESULTS: Among 1271 women enrolled, median age was 22â years (IQR 19-27) and gestational age was 22â weeks (IQR 18-26); most (78%) were married and had uncircumcised male partners (69%). Prevalent T. vaginalis was detected in 81 women (6%) at enrolment. Among women without T. vaginalis at enrolment, 112 had T. vaginalis detected during 1079 person-years of follow-up (10.4 per 100 person-years). After adjustment for socio-economic factors, male partner circumcision status, pregnancy status and other STIs, T. vaginalis incidence was higher during pregnancy than post partum (22.3 vs 7.7 per 100 person-years, adjusted HR (aHR) 3.68, 95% CI 1.90 to 7.15, p<0.001). Women with circumcised male partners had a 58% lower risk of incident T. vaginalis compared with women with uncircumcised partners (aHR 0.42, 95% CI 0.23 to 0.76, p=0.004). Employed women had lower risk of incident T. vaginalis than unemployed women (aHR 0.49, 95% CI 0.31 to 0.79, p=0.003); recent STI was associated with increased T. vaginalis risk (aHR 2.97, 95% CI 1.49 to 5.94, p=0.002). CONCLUSIONS: T. vaginalis was relatively common in this peripartum cohort. Male circumcision may confer benefits in preventing T. vaginalis.

BACKGROUND: Patient-delivered partner treatment (PDPT) for sexually transmitted infections (STIs) increases rates of partner treatment and decreases reinfection, but has not been evaluated during pregnancy. METHODS: This prospective cohort was nested within a larger study of peripartum HIV acquisition. Participants with microbiologic diagnosis of Chlamydia trachomatis, Neisseria gonorrhoeae, and/or Trichomonas vaginalis were screened for participation. Questionnaires were administered to determine PDPT acceptability and barriers. Women were reassessed at least 30 days to determine partner treatment and reinfection. Women whose partners did or did not receive PDPT were compared. RESULTS: One hundred twelve (22.2%) women in the parent cohort had a treatable STI; 78 within the PDPT study period, of whom 66 were eligible and 59 (89.3%) accepted PDPT. Fifty-one women had PDPT outcome data, 37 (73%) of whom reported partners treated with PDPT. Fourteen women (27%) refused or did not deliver partner treatment. Median age was 22 years (interquartile range, 20-26 years) and 88% were married. Compared with women who delivered PDPT, those who did not were more likely to have a partner living far away (23% vs. 0%, P = 0.004) and to report current intimate partner violence (14% vs. 0%, P = 0.02). Reported PDPT barriers included fear of partner's anger/abuse (5%) and accusations of being STI source (5%). CONCLUSION: Patient-delivered partner treatment was acceptable and feasible for pregnant/postpartum Kenyan women and may reduce recurrent STIs in pregnancy.

BACKGROUND: The effect of maternal HIV on infant Mycobacterium tuberculosis (Mtb) infection risk is not well-characterized. METHODS: Pregnant women with/without HIV and their infants were enrolled in a longitudinal cohort in Kenya. Mothers had interferon gamma-release assays (QFT-Plus) and tuberculin skin tests (TST) at enrollment in pregnancy; children underwent TST at 12 and 24 months of age. We estimated the incidence and correlates of infant TST-positivity using Cox proportional hazards regression. RESULTS: Among 322 infants, 170 (53%) were HIV-exposed and 152 (47%) were HIV-unexposed. Median enrollment age was 6.6 weeks [interquartile range (IQR): 6.1-10.0]; most received Bacillus Calmette-Guerin (320, 99%). Thirty-nine (12%) mothers were TST-positive; 102 (32%) were QFT-Plus-positive. Among HIV-exposed infants, 154 (95%) received antiretrovirals for HIV prevention and 141 (83%) of their mothers ever received isoniazid preventive therapy (IPT). Cumulative 24-month infant Mtb infection incidence was 3.6/100 person-years (PY) [95% confidence interval (CI): 2.4-5.5/100 PY]; 5.4/100 PY in HIV-exposed infants (10%, 17/170) versus 1.7/100 PY in HIV-unexposed infants (3.3%, 5/152) [hazard ratio (HR): 3.1 (95% CI: 1.2-8.5)]. More TST conversions occurred in the first versus second year of life [5.8 vs. 2.0/100 PY; HR: 2.9 (95% CI: 1.0-10.1)]. Infant TST-positivity was associated with maternal TST-positivity [HR: 2.9 (95% CI: 1.1-7.4)], but not QFT-Plus-positivity. Among HIV-exposed children, Mtb infection incidence was similar regardless of maternal IPT. CONCLUSIONS: Mtb infection incidence (by TST) by 24 months of age was ~3-fold higher among HIV-exposed children, despite high maternal IPT uptake. Overall, more TST conversions occurred in the first 12 months compared to 12-24 months of age, similar in both HIV-exposed and HIV-unexposed children.
