Background: Antenatal iron and folic acid (IFA) supplementation remains an effective strategy in the prevention of maternal anemia and low birthweight and is universally recommended by WHO. However, uptake of IFA has varied globally due to challenges with acceptability, supply and distribution, counselling and knowledge, and access to health services. In Botswana, nearly one-third of pregnant women engaged in antenatal care do not receive IFA, despite it being standard of care. The objectives of this study were to assess knowledge of and barriers and facilitators to IFA supplementation before and during pregnancy., Methods: We conducted qualitative interviews with two key stakeholder groups at two different levels-the individual level (pregnant women) and the service delivery level (health care providers). Here, we present results from interviews with pregnant women at two representative antenatal clinic sites in Botswana in 2022., Results: Pregnant women were motivated to be healthy and were knowledgeable about the benefits of supplementation during pregnancy to mothers and their infants; however, women knew more about the benefits of iron than folic acid. Most women were in favor of receiving IFA supplementation prior to pregnancy and receiving fortified foods. Several key barriers were identified: lack of supplement availability in the clinics, poverty, side effects, number of tablets, and adherence. Approaches to overcome these barriers included improving supplement availability, improving health education, increasing supply of nutritious and fortified foods, backyard gardens, and increasing family and monetary support., Conclusions: Our study identified a need to 1) increase the availability of supplementation at antenatal clinics and 2) improve education regarding supplementation to include information about the benefits of folic acid and other micronutrients. Implementation research is needed to ascertain whether increasing supply and improving education could increase utilization of supplementation during pregnancy, with the ultimate goal of improving maternal and infant outcomes., Competing Interests: Declarations. Ethics approval and consent to participate: The study was approved by the Institutional Review Board at the University of Pennsylvania Perelman School of Medicine and by the Human Research Development Council (HRDC) in Botswana. All personnel involved in the conduct of this study had completed Human Subjects Protection Training.

Importance: Nonresponse to hepatitis B vaccine is common among people with HIV, resulting in vulnerability to infection with hepatitis B virus (HBV)., Objective: To compare the seroprotection response achieved with a 2-dose (noninferiority, 10% margin) and a 3-dose hepatitis B vaccine with a cytosine phosphoguanine adjuvant (HepB-CpG vaccine) vs a conventional 3-dose hepatitis B vaccine with an aluminum hydroxide adjuvant (HepB-alum vaccine) in people with HIV and prior nonresponse to HepB-alum vaccine., Design, Setting, and Participants: This phase 3, open-label, randomized clinical trial included people with HIV receiving antiretroviral therapy (CD4 cell count ≥100 cells/μL and HIV RNA <1000 copies/mL) without past or present serological evidence of having HBV or a response to hepatitis B vaccine. From December 2020 to February 2023, 561 adults were enrolled in the study at 41 sites in 10 countries in Africa, Asia, North America, and South America with follow-up for the primary outcome analysis through September 4, 2023., Interventions: Participants were randomly assigned to receive 2 doses of HepB-CpG vaccine administered intramuscularly at weeks 0 and 4; 3 doses of HepB-CpG vaccine administered intramuscularly at weeks 0, 4, and 24; or 3 doses of HepB-alum vaccine administered intramuscularly at weeks 0, 4, and 24., Main Outcomes and Measures: The primary outcome was a seroprotection response to hepatitis B vaccine (defined as level of antibody titer against hepatitis B surface antigen [HBsAg] ≥10 mIU/mL) at week 12 for the 2-dose regimen (8 weeks after dose 2) and at week 28 for 3-dose regimens (4 weeks after dose 3). Key secondary outcomes included seroprotection response at additional time points, antibody titer against HBsAg, and adverse events within 4 weeks of hepatitis B vaccination., Results: Of 561 participants included in the analysis (median age, 46 years [IQR, 31-56 years]); 64% were male; 17% of participants were Asian, 42% were Black, and 35% were White), a seroprotection response was achieved in 93.1% who received 2 doses of HepB-CpG vaccine (n = 174), in 99.4% who received 3 doses of HepB-CpG vaccine (n = 169), and in 80.6% who received 3 doses of HepB-alum vaccine (n = 165). The stratified difference in seroprotection response between the 2-dose HepB-CpG vaccine group and the 3-dose HepB-alum vaccine group was 12.5% (97.5% CI, 4.1%-20.9%), achieving noninferiority and indicating superiority. The 3-dose HepB-CpG vaccine regimen was superior to the 3-dose HepB-alum vaccine regimen (stratified difference in seroprotection response, 18.4% [repeated 97.5% CI, 10.4%-26.2%]). By week 12, more than 90% of participants who received HepB-CpG vaccine achieved a seroprotection response. The 3-dose regimen of HepB-CpG vaccine achieved a higher proportion of participants with antibody titer against HBsAg greater than 1000 mIU/mL (78.1%) vs the other 2 regimen groups (26.4% for 2 doses of HepB-CpG vaccine and 35.2% for 3 doses of HepB-alum vaccine). No unexpected safety issues were observed., Conclusions and Relevance: Among people with HIV and nonresponse to prior hepatitis B vaccination, both the 2-dose and 3-dose regimens of HepB-CpG vaccine achieved a superior seroprotection response compared with 3 doses of HepB-alum vaccine., Trial Registration: ClinicalTrials.gov Identifier: NCT04193189.

Background: There are limited data on the epidemiology of sexually transmitted infections (STI) and their contribution to adverse birth outcomes (ABO) in sub-Saharan Africa (SSA). We performed a case-control study to assess the prevalence of STI and their association with ABO among women attending Queen Elizabeth Central Hospital, Blantyre, Malawi., Methods: A composite case definition for ABO included stillborn, preterm and low birthweight infants and infants admitted to neonatal intensive care unit within 24 hours of birth. Following recruitment of an infant with an ABO, the next born healthy infant was recruited as a control. Multiplex PCR for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and Trichomonas vaginalis (TV) was performed on maternal vaginal swabs. HIV and syphilis status was determined on maternal and infant serum. For syphilis, we used combined treponemal/non-treponemal rapid point-of-care tests in parallel with rapid plasma reagin tests, PCR for Treponema pallidum and clinical parameters to diagnose and stage the infection. We compared STI positivity between cases and controls., Results: We included 259 cases and 251 controls. Maternal prevalence of STI was 3.1%, 2.7% and 17.1% for NG, CT and TV, respectively. Maternal prevalence of untreated syphilis was 2.0% and 6.1% for early stage and late/unknown stage, respectively; prevalence of treated syphilis was 2.7%. The HIV prevalence was 16.5%. HIV infection significantly increased the odds for ABO (OR=3.31; 95% CI 1.10 to 9.91) as did NG positivity (OR=4.30; 95% CI 1.16 to 15.99). We observed higher rates of ABO among women with untreated maternal syphilis (early: OR=7.13; 95% CI 0.87 to 58.39, late/unknown stage: OR=1.43; 95% CI 0.65 to 3.15). Maternal TV and CT infections were not associated with ABO., Conclusion: STI prevalence among pregnant women in Malawi is comparable to other SSA countries. HIV, NG and untreated syphilis prevalence was higher among women with ABO compared with women with healthy infants., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: In the International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) 2010/VESTED study, pregnant women were randomized to initiate dolutegravir (DTG) + emtricitabine (FTC)/tenofovir alafenamide (TAF), DTG + FTC/tenofovir disoproxil fumarate (TDF), or efavirenz (EFV)/FTC/TDF., Methods: We assessed red blood cell (RBC) folate concentrations at maternal study entry and delivery, and infant birth. RBC folate outcomes were (1) maternal change entry to delivery (trajectory), (2) infant, and (3) ratio of infant-to-maternal delivery. Generalized estimating equation models for each log(folate) outcome were fit to estimate adjusted geometric mean ratio (Adj-GMR)/GMR trajectories (Adj-GMRTs) of each arm comparison in 340 mothers and 310 infants., Results: Overall, 90% of mothers received folic acid supplements and 78% lived in Africa. At entry, median maternal age was 25 years, gestational age was 22 weeks, CD4 count was 482 cells/μL, and log10 HIV RNA was 3 copies/mL. Entry RBC folate was similar across arms. Adj-GMRT of maternal folate was 3% higher in the DTG + FTC/TAF versus EFV/FTC/TDF arm (1.03 [95% confidence interval {CI}, 1.00-1.06]). The DTG + FTC/TAF arm had an 8% lower infant-maternal folate ratio (0.92 [95% CI, .78-1.09]) versus EFV/FTC/TDF., Conclusions: Results are consistent, with no clinically meaningful differences between arms for all RBC folate outcomes, and they suggest that cellular uptake of folate and folate transport to the infant do not differ in pregnant women starting DTG- versus EFV-based antiretroviral therapy., Clinical Trials Registration: NCT03048422., Competing Interests: Potential conflicts of interest.

Background: HIV-1 antiretroviral therapy (ART) alters hormonal contraceptive levels delivered via intravaginal ring (IVR) in a regimen specific manner. We explored the role of the IVR on vaginal microbial communities, vaginal short chain fatty acids (SCFAs), vaginal HIV shedding, and the effect of vaginal microbes on hormone concentrations in cisgender women with HIV (WWH)., Methods: Vaginal microbes were assessed by 16S RNA sequencing of weekly vaginal swabs, vaginal SCFA by mass spectrometry, HIV-1 shedding by nucleic acid amplification on vaginal aspirates, and bacterial vaginosis by Nugent scoring from 74 participants receiving an etonorgestrel/ethinyl estradiol (ENG/EE) intravaginal ring while on no ART (N=25), efavirenz-based ART (N=25), or atazanavir-based ART (N=24)., Results: At baseline, microbial communities of the 64 substudy eligible participants robustly classified as Lactobacillus crispatus--dominant (n=8), L. gasseri-dominant (n=2), L. iners-dominant (n=17), or mixed anaerobic communities (n=37). During IVR therapy, there was an increased probability of Lactobacillus-dominant community state types (CSTs) (odds-ratio=1.61, p=0.04). Vaginal CSTs were associated with Nugent scores. Bacterial vaginosis-associated bacteria were associated with significantly higher and L. iners with lower Nugent Scores (all p adj <0.1). Lactic acid levels were correlated with the relative abundance of Lactobacillus species (r2=0.574; p<0.001). Vaginal shedding of HIV-1 was less common in women with L. crispatus-dominant microbiomes (p=0.04). Mixed anaerobic vaginal communities modulated EE concentrations in a regimen-specific manner., Conclusions: Combined ENG/EE IVR therapy was associated with an increase in Lactobacillus-dominant vaginal microbial communities in WWH and may benefit those with bacterial vaginosis. EE levels were altered by the vaginal microbiota., (Published by Oxford University Press on behalf of Infectious Diseases Society of America 2024.)

Objectives: To develop a pragmatic twice daily lamivudine dosing strategy for preterm infants from 24 to 37 completed weeks of gestation., Methods: Data were combined from eight pharmacokinetic studies in neonates and infants receiving lamivudine oral solution. A population pharmacokinetic model was developed using non-linear mixed effects regression. Different lamivudine dosing strategies, stratified by gestational age at birth (GA) bands, were simulated in a virtual population of preterm infants, aimed at maintaining lamivudine drug exposures (AUC0-12) within a reference target range of 2.95 to 13.25 µg·h/mL, prior to switching to WHO-weight band doses when ≥4 weeks of age and weighing ≥3 kg., Results: A total of 154 infants (59% female) contributed 858 lamivudine plasma concentrations. Median (range) GA at birth was 38 (27-41) weeks. At the time of first pharmacokinetic sampling infants were older with median postnatal age (PNA) of 6.3 (0.52-26.6) weeks. Lamivudine concentrations were described by a one-compartment model, with CL/F and V/F allometrically scaled to weight. Maturation of CL/F was described using an Emax model based on PNA. CL/F was also adjusted on GA to allow extrapolation for extreme prematurity. Simulations predicted an optimal lamivudine dosing for infants GA ≥24 to <30 weeks of 2 mg/kg twice daily from birth until weighing 3 kg; and for GA ≥30 to <37 weeks, 2 mg/kg twice daily for the first 4 weeks of life, followed by 4 mg/kg twice daily until weighing 3 kg., Conclusions: Model-based predictions support twice daily pragmatic GA band dosing of lamivudine for preterm infants, but clinical validation is warranted., (© The Author(s) 2024.

Background: Low-cost, scalable strategies are necessary to reach the UNAIDS 2030 target of ending HIV as a public health threat. Use of treatment partners, informal caregivers selected by people living with HIV to support antiretroviral therapy adherence, is one such strategy that is included in many countries' HIV guidelines, including Botswana, a country with high HIV prevalence., Method: From June 2021 to June 2022, we pilot tested a clinic-based treatment partner intervention ("Mopati"), including standardized language for providers to guide patients on treatment partner selection and workshops to train treatment partners on providing non-directive support to patients using a non-confrontational, non-judgmental approach. Sixty unsuppressed patients (30 per clinic) and 45 treatment partners (17 intervention, 28 control) were recruited from an intervention-control clinic matched-pair in Gaborone, Botswana., Results: Mopati had medium-to-large effects on increasing patients' adherence, adherence self-efficacy, intrinsic adherence motivation, and perceived non-directive support from treatment partners, and decreasing treatment partner caregiver burden. Aggregate viral suppression rates significantly increased in the intervention (vs. control) clinic. Qualitative data from 14 clinic staff, 21 patients, and 16 treatment partners indicated that Mopati was viewed as effective. Providers said the guidance empowered them to be proactive in communicating about adherence; most reported using the guidance., Conclusion: This study shows preliminary support for the use of treatment partners in HIV care, and further evidence for interventions that leverage patients' existing support. This research can inform ways to improve adherence to HIV treatment as well as the treatment of HIV-related comorbid conditions in lower-resource settings., Trial Registration: ClinicalTrials.gov Identifier: NCT04796610., (© 2024.

Introduction: Women with HIV (WHIV) have higher risks of adverse pregnancy outcomes, particularly in the absence of antiretroviral treatment(ART), and timing of ART may impact risk., Methods: In IMPAACT 2010 (VESTED), 643 pregnant WHIV in 9 countries were randomized 1:1:1 to initiate ART: dolutegravir (DTG)+emtricitabine(FTC)/tenofovir alafenamide(TAF); DTG+FTC/tenofovir disoproxil fumarate (TDF) or efavirenz (EFV)/FTC/TDF. We describe adverse pregnancy outcomes in women with a subsequent pregnancy during 50 weeks of postpartum follow-up: spontaneous abortion (<20 weeks), stillbirth (≥20 weeks), preterm delivery (<37 weeks) and small-for-gestational-age (SGA)., Results: Of 643 women, 19 (3%) had 20 subsequent pregnancies while receiving ART at conception: DTG/FTC/TAF(3), DTG/FTC/TDF(2), EFV/FTC or lamivudine(3TC)/TDF(12), EFV/abacavir/3TC (1) and no ART(1). Four spontaneous abortions, 3 stillbirths, and 1 induced abortion occurred. Three (25%) of 12 liveborn infants were preterm (24-, 26- and 36-weeks' gestation). Only 12 (60%) subsequent pregnancies resulted in live birth, and at least 1 adverse pregnancy outcome occurred in 11/19 (58%) (induced abortion excluded). Of 7 women who experienced spontaneous abortion/stillbirth in the subsequent pregnancy, 4 experienced a stillbirth and 1 a neonatal death as outcomes of their earlier index pregnancy. No congenital anomalies were reported., Conclusions: Adverse pregnancy outcomes were common in this cohort of WHIV who conceived on ART shortly after an index pregnancy, 35% ended in stillbirth or spontaneous abortion. The majority of fetal losses occurred in women with recent prior pregnancy loss. Data from larger cohorts of WHIV conceiving on ART and surveillance are needed to elucidate rates and predictors of adverse pregnancy outcome.

Amphotericin B has long been crucial for treating many serious infectious diseases, such as invasive fungal infections and visceral leishmaniasis, particularly for patients who are immunocompromised, including those with advanced HIV infection. The conventional amphotericin B deoxycholate formulation has largely been replaced in high-income countries with liposomal amphotericin B (LAmB), which has many advantages, including lower rates of adverse events, such as nephrotoxicity and anaemia. Despite an evident need for LAmB in low-income and middle-income countries, where mortality from invasive fungal infections is still substantial, many low-income and middle-income countries still often use the amphotericin B deoxycholate formulation because of a small number of generic formulations and the high price of the originator LAmB. The pricing of LAmB is also highly variable between countries. Overcoming supply barriers through the availability of additional quality-assured, generic formulations of LAmB at accessible prices would substantially facilitate equitable access and have a substantial effect on mortality attributable to deadly fungal infections., Competing Interests: Declaration of interests JNJ reports funding from National Institute for Health and Care Research and US Centers for Disease Control and Prevention.

Objective: To evaluate the impact of screening and treating asymptomatic pregnant women for Chlamydia (C.) trachomatis and Neisseria (N.) gonorrhoeae infections on the frequency of preterm birth or low birthweight infants in Botswana., Design: Non-randomised, cluster-controlled trial., Setting: Four antenatal care clinics in Gaborone, Botswana., Population: Pregnant women aged ≥15 years, attending a first antenatal care visit, ≤27 weeks of gestation and without urogenital symptoms were eligible., Methods: Participants in the intervention clinics received screening (GeneXpert®, Cepheid) during pregnancy and at the postnatal visit. Participants in the standard-of-care clinics received screening at the postnatal visit only. We used multivariable logistic regression and post-estimation predictive margins analysis. Post-hoc analysis was conducted among sub-samples stratified by parity., Main Outcome Measures: Preterm birth (<37 weeks of gestation) and low birthweight (<2500 g)., Results: After controlling for parity, hypertension, antenatal care visits and clinic site, the predicted prevalence of preterm birth or low birthweight was lower in the intervention arm (11%) compared with the standard-of-care arm (16%) (adjusted odds ratio [aOR] 0.59; 95% confidence interval [CI] 0.28-1.24). In post-hoc analysis, the intervention was more effective than the standard-of-care (aOR 0.20; 95% CI 0.07-0.64) among nulliparous participants., Conclusion: A C. trachomatis and N. gonorrhoeae infection screening and treatment intervention among asymptomatic pregnant women may have reduced preterm birth or low birthweight outcomes, but results were not statistically significant. Post-hoc analysis found that the intervention reduced adverse outcomes among nulliparous participants., (© 2024 The Authors.

Cryptococcosis is a major worldwide disseminated invasive fungal infection. Cryptococcosis, particularly in its most lethal manifestation of cryptococcal meningitis, accounts for substantial mortality and morbidity. The breadth of the clinical cryptococcosis syndromes, the different patient types at-risk and affected, and the vastly disparate resource settings where clinicians practice pose a complex array of challenges. Expert contributors from diverse regions of the world have collated data, reviewed the evidence, and provided insightful guideline recommendations for health practitioners across the globe. This guideline offers updated practical guidance and implementable recommendations on the clinical approaches, screening, diagnosis, management, and follow-up care of a patient with cryptococcosis and serves as a comprehensive synthesis of current evidence on cryptococcosis. This Review seeks to facilitate optimal clinical decision making on cryptococcosis and addresses the myriad of clinical complications by incorporating data from historical and contemporary clinical trials. This guideline is grounded on a set of core management principles, while acknowledging the practical challenges of antifungal access and resource limitations faced by many clinicians and patients. More than 70 societies internationally have endorsed the content, structure, evidence, recommendation, and pragmatic wisdom of this global cryptococcosis guideline to inform clinicians about the past, present, and future of care for a patient with cryptococcosis., Competing Interests: Declaration of interests AA reports grants from the Agence Nationale de la Recherche; serving as a consultant to Gilead Sciences; receiving speaking honoraria from Gilead Sciences and PR Edition; travel support from Gilead sciences and Pfizer; and patents with the Institut Pasteur.

Introduction: VESTED (NCT03048422) compared the safety and efficacy of three antiretroviral treatment ( ART ) regimens in pregnant and postpartum women: dolutegravir+emtricitabine/tenofovir alafenamide fumarate; dolutegravir+emtricitabine/tenofovir disoproxil fumarate ( TDF ); efavirenz/emtricitabine/TDF. Vertical HIV transmission ( VT ) occurred to 4/617 (0.60%) live-born infants, who were evaluated for HIV drug resistance ( HIVDR ) and other risk factors., Setting: In 2018-2020, pregnant (weeks-14-28) women living with HIV and ≤14 days of ART were enrolled at 22 international sites and followed with their infants through 50 weeks postpartum., Methods: HIV sequences derived by single genome amplification ( SGA ) from longitudinally collected specimens were assessed from VT Cases for HIVDR in protease, reverse transcriptase, integrase, and the nef 3'polypurine tract ( 3'PPT )., Results: The four Case mothers were prescribed efavirenz-based-ART for 1-7 days prior to randomization to study ART. Their infants received postnatal nevirapine+/-zidovudine prophylaxis and were breastfed. A total of 833 SGA sequences were derived. The "major" (Stanford HIVDR Score ≥60) non-nucleoside reverse transcriptase inhibitor ( NNRTI ) mutation (K103N) was detected persistently in one viremic mother, and likely contributed to VT of HIVDR. Major NNRTI HIVDR mutations were detected in all three surviving infants. No integrase, nor high frequencies of 3'PPT mutations conferring dolutegravir HIVDR were detected. The timing of HIV infant diagnosis, plasma HIV RNA levels and HIVDR suggests one in utero , one peripartum, one early, and one late breastfeeding transmission., Conclusions: VT was rare. New-onset NNRTI HIVDR in Case mothers was likely from efavirenz-ART prescribed prior to study dolutegravir-ART, and in one case appeared transmitted to the infant despite nevirapine prophylaxis., Competing Interests: Conflicts of Interest: All authors declare no conflicts of interest.

No accurate and rapid diagnostic test exists for tuberculous meningitis (TBM), leading to delayed diagnosis. We leveraged data from multiple studies to improve the predictive performance of diagnostic models across different populations, settings, and subgroups to develop a new predictive tool for TBM diagnosis. We conducted a systematic review to analyze eligible datasets with individual-level participant data (IPD). We imputed missing data and explored three approaches: stepwise logistic regression, classification and regression tree (CART), and random forest regression. We evaluated performance using calibration plots and C-statistics via internal-external cross-validation. We included 3,761 individual participants from 14 studies and nine countries. A total of 1,240 (33%) participants had "definite" (30%) or "probable" (3%) TBM by case definition. Important predictive variables included cerebrospinal fluid (CSF) glucose, blood glucose, CSF white cell count, CSF differential, cryptococcal antigen, HIV status, and fever presence. Internal validation showed that performance varied considerably between IPD datasets with C-statistic values between 0.60 and 0.89. In external validation, CART performed the worst (C = 0.82), and logistic regression and random forest had the same accuracy (C = 0.91). We developed a mobile app for TBM clinical prediction that accounted for heterogeneity and improved diagnostic performance (https://tbmcalc.github.io/tbmcalc). Further external validation is needed.

Women living with HIV and breast cancer have poorer survival than HIV-negative women. Efavirenz-estrogen interactions are documented; however, the survival impact is unknown. Survival between women with estrogen-receptor positive breast cancer taking efavirenz (n = 38) and nonefavirenz regimens (n = 51) were compared. The 5-year overall-survival was 48.9% [95% confidence interval (CI) 33.0-72.2 and 51.1% (95% CI 34.0-76.8)] in the efavirenz and nonefavirenz groups, respectively suggesting efavirenz is unlikely driving poorer survival in women living with HIV and estrogen-receptor positive breast cancer., (Copyright © 2024 The Author(s).

Objective: The World Health Organization (WHO) recommended addition of local anesthetic to reduce the intense pain of intramuscular injection of 50% Magnesium Sulphate (MgSO 4 ) salt solution has been found to be ineffective. We tested whether giving the local anesthetic 5 min before the MgSO 4 injection would reduce pain., Methods: We conducted a prospective cross-over trial where each participant with pre-eclampsia or eclampsia received sequential and mixed injection methods in random sequence during sequential MgSO 4 administrations. Pain and preference were assessed using descriptive words, a numeric pain scale and direct comparison between the two injection methods. Differences were measured using the Wilcoxon signed rank test, risk ratios with 95% confidence intervals and the Chi squared or Fisher's test. The administration techniques were refined based on an initial pilot of 8 participants., Results: We enrolled 49 consented participants and analysed data from 41 post-pilot participants The sequential injection method had a non-significantly lower mean pain score than the mixed injection method (3.1 vs. 3.3, p  = 0.44). Severe pain was reported for 3/41 vs. 9/41, p  = 0.12. The sequential injection method was perceived to be more painful by 13 (37%) vs. 22 (63%) participants ( p  = 0.03). The sequential injection was preferred by 21(60%) vs. 14 participants (40%) ( p  = 0.1)., Conclusion: Our results consistently favoured the novel sequential injection method. The lack of statistical significance for most results is not surprising given the small sample size. Given the potential for clinically important benefits to women, a larger study to confirm these results is justified., Clinical Trial Registration: https://pactr.samrc.ac.za/, Identifier (PACTR202201521544765)., Competing Interests: GJH has a conflict of interest with respect to the MaternaWell Tray for blood loss monitoring after birth and receives royalties from UpToDate.

Background: Botswana serves as a model of success for HIV with 95% of people living with HIV (PLWH) virally suppressed. Yet, only 19% of PLWH and hypertension have controlled blood pressure. To address this gap, InterCARE, a care model that integrates HIV and hypertension care through a) provider training; b) adapted electronic health record; and c) treatment partners (peer support), was designed. This study presents results from our baseline assessment of the determinants and factors used to guide adaptations to InterCARE implementation strategies prior to a hybrid type 2 effectiveness-implementation study., Methods: This study employed a convergent mixed methods design across two clinics (one rural, one urban) to collect quantitative and qualitative data through facility assessments, 100 stakeholder surveys (20 each PLWH and hypertension, existing HIV treatment partners, clinical healthcare providers (HCPs), and 40 community leaders) and ten stakeholder key informative interviews (KIIs). Data were analyzed using descriptive statistics and deductive qualitative analysis organized by the Consolidated Framework for Implementation Research (CFIR) and compared to identify areas of convergence and divergence., Results: Although 90.3% of 290 PLWH and hypertension at the clinics were taking antihypertensive medications, 52.8% had uncontrolled blood pressure. Results from facility assessments, surveys, and KIIs identified key determinants in the CFIR innovation and inner setting domains. Most stakeholders (> 85%) agreed that InterCARE was adaptable, compatible and would be successful at improving blood pressure control in PLWH and hypertension. HCPs agreed that there were insufficient resources (40%), consistent with facility assessments and KIIs which identified limited staffing, inconsistent electricity, and a lack of supplies as key barriers. Adaptations to InterCARE included a task-sharing strategy and expanded treatment partner training and support., Conclusions: Integrating hypertension services into HIV clinics was perceived as more advantageous for PLWH than the current model of hypertension care delivered outside of HIV clinics. Identified barriers were used to adapt InterCARE implementation strategies for more effective intervention delivery., Trial Registration: ClinicalTrials.gov, ClinicalTrials.gov Identifier: NCT05414526 .

Background: Mortality associated with HIV-associated cryptococcal meningitis remains high even in the context of clinical trials (24-45% at 10 weeks); mortality at 12-months is up to 78% in resource limited settings. Co-prevalent tuberculosis (TB) is common and preventable, and likely contributes to poor patient outcomes. Innovative strategies to increase TB preventative therapy (TPT) provision and uptake within this high-risk group are needed., Protocol: The IMPROVE trial (Integrated management of cryptococcal meningitis and concurrent opportunistic infections to improve outcomes in advanced HIV disease) is a nested open label, two arm, randomised controlled strategy trial to evaluate the safety (adverse events) and feasibility (adherence and tolerability) of two ultra-short course TPT strategies, in the context of recent diagnosis and treatment for cryptococcal meningitis. We will enrol 205 adults with HIV-associated cryptococcal meningitis from three hospitals in Uganda. Participants will be randomised to either inpatient initiation (early) or outpatient initiation (standard, week 6) of 1HP (one month of isoniazid and rifapentine). Participant follow-up is to include TB screening, 1HP pill counts and tolerability reviews on alternate weeks until week-18. The trial primary endpoint is TB-disease free 1HP treatment completion at 18-weeks, secondary endpoints: 1HP treatment completion, 1HP discontinuation, grade ≥3 adverse events and serious adverse events, drug-induced liver injury, incident active TB, 18-week survival; rifapentine, fluconazole and dolutegravir concentrations will be measured with intensive sampling in a pharmacokinetic sub-study of 15 eligible participants., Discussion: The IMPROVE trial will provide preliminary safety and feasibility data to inform 1HP TPT strategies for adults with advanced HIV disease and cryptococcal meningitis. The potential impact of demonstrating that inpatient initiation of 1HP TPT is safe and feasible amongst this high-risk subpopulation with advanced HIV disease, would be to expand the range of clinical encounters in which clinicians can feasibly provide 1HP, and therefore increase the reach of TPT as a preventative intervention., Isrctn Registration: ISRCTN18437550 (05/11/2021)., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Ellis J et al.)

Background: Partner notification and treatment for sexually transmitted infections are critical to prevent reinfection and reduce transmission. However, partner treatment rates are low globally. Expedited partner therapy (EPT), in which the patient delivers treatment directly to their partner, may result in more partners treated. We assessed partner notification and treatment outcomes among pregnant women in Gaborone, Botswana, including EPT intent, uptake, and effectiveness., Methods: The Maduo study was a cluster-controlled trial evaluating the effect of antenatal Chlamydia trachomatis and Neisseria gonorrhoeae infection screening in pregnant women. The intervention arm received screening at first antenatal care (ANC), third-trimester, and postnatal care visits. The standard-of-care arm received screening postnatally. Participants screening positive were given options for partner treatment: contact slips, in-clinic treatment, or EPT. Self-reported partner notification and treatment outcomes were assessed at test-of-cure visit., Results: Of 51 women who screened positive for C. trachomatis / N. gonorrhoeae at first ANC and returned for test of cure, 100% reported notifying their partner and 48 (94.1%) reported their partner received treatment. At third trimester 100% (n = 5), reported partners were treated. Before testing, EPT intent was lower than EPT uptake at all time points (first ANC: 17.9% vs. 80.4%; third-trimester: 57.1% vs. 71.4%; postnatal care: 0% vs. 80.0%). Partner treatment success was 100% among EPT users compared with 70% among nonusers ( P = 0.006)., Conclusions: Partner notification and treatment success was high in this population. Despite low pretest intent to use EPT, uptake was high and associated with greater partner treatment success. Our findings suggest that EPT may be a successful partner treatment strategy to pursue in low- and middle-income countries., Competing Interests: Conflict of Interest and Sources of Funding: The authors have no competing interests to disclose., (Copyright © 2024 American Sexually Transmitted Diseases Association.

Background: The COVID-19 pandemic brought challenges requiring timely health data sharing to inform accurate decision-making at national levels. In Botswana, we adapted and integrated the Research Electronic Data Capture (REDCap) and the District Health Information System version 2 (DHIS2) platforms to support timely collection and reporting of COVID-19 cases. We focused on establishing an effective COVID-19 data flow at the national public health laboratory, being guided by the needs of health care professionals at the National Health Laboratory (NHL). This integration contributed to automated centralized reporting of COVID-19 results at the Ministry of Health (MOH)., Objective: This paper reports the experiences, challenges, and lessons learned while designing, adapting, and implementing the REDCap and DHIS2 platforms to support COVID-19 data management at the NHL in Botswana., Methods: A participatory design approach was adopted to guide the design, customization, and implementation of the REDCap platform in support of COVID-19 data management at the NHL. Study participants included 29 NHL and 4 MOH personnel, and the study was conducted from March 2, 2020, to June 30, 2020. Participants' requirements for an ideal COVID-19 data management system were established. NVivo 11 software supported thematic analysis of the challenges and resolutions identified during this study. These were categorized according to the 4 themes of infrastructure, capacity development, platform constraints, and interoperability., Results: Overall, REDCap supported the majority of perceived technical and nontechnical requirements for an ideal COVID-19 data management system at the NHL. Although some implementation challenges were identified, each had mitigation strategies such as procurement of mobile Internet routers, engagement of senior management to resolve conflicting policies, continuous REDCap training, and the development of a third-party web application to enhance REDCap's capabilities. Lessons learned informed next steps and further refinement of the REDCap platform., Conclusions: Implementation of REDCap at the NHL to streamline COVID-19 data collection and integration with the DHIS2 platform was feasible despite the urgency of implementation during the pandemic. By implementing the REDCap platform at the NHL, we demonstrated the possibility of achieving a centralized reporting system of COVID-19 cases, hence enabling timely and informed decision-making at a national level. Challenges faced presented lessons learned to inform sustainable implementation of digital health innovations in Botswana and similar resource-limited countries., (©Kagiso Ndlovu, Kabelo Leonard Mauco, Onalenna Makhura, Robin Hu, Nkwebi Peace Motlogelwa, Audrey Masizana, Emily Lo, Thongbotho Mphoyakgosi, Sikhulile Moyo.

The WHO African region bears a disproportionate burden of morbidity and mortality related to chronic hepatitis B virus (HBV) infection and accounts for an estimated 70% of new HBV infections worldwide. We investigated the extent to which HBV clinical trials represented populations in this region by searching the WHO International Clinical Trials Registry Platform and ClinicalTrials.gov for interventional clinical trials published in English between database inception and May 29, 2023, using the search term "Hepatitis B". We identified 1804 unique clinical trials, of which 18 (1·0%) recorded involvement of the WHO African region. There is no evidence that the number of HBV clinical trials in this region has improved over time. The diversity of new interventions and industry sponsorship in the WHO African region were low, with trials of HBV comparing poorly with those of other endemic infectious diseases (eg, malaria, HIV, and SARS-CoV-2). HBV research and clinical trial investigations have neglected the WHO African region, leading to profound health inequities. HBV clinical trials are urgently needed to evaluate the efficacy of newly discovered therapeutics and to ensure that interventions can be equitably distributed and deployed as they become available., Competing Interests: Declaration of interests MD, EW, and PCM receive funding from The Francis Crick Institute.

Introduction: Monthly intravenous infusion of broadly neutralizing monoclonal antibodies may be an attractive alternative to daily oral antiretroviral treatment for children living with HIV. However, acceptability among caregivers remains unknown., Methods: We evaluated monthly infusion of dual bNAbs (VRCO1LS and 10-1074) as a treatment alternative to ART among children participating in the Tatelo Study in Botswana. Eligible children aged 2-5 years received 8-32 weeks of bNAbs overlapping with ART, and up to 24 weeks of bNAbs alone as monthly intravenous infusion. Using closed-ended questionnaires, we evaluated caregiver acceptability of each treatment strategy prior to the first bNAb administration visit (pre-intervention) and after the completion of the final bNAb administration visit (post-intervention)., Results: Twenty-five children completed the intervention phase of the study, and acceptability data were available from 24 caregivers at both time points. Responses were provided by the child's mother at both visits (60%), an extended family member at both visits (28%), or a combination of mother and an extended family member (12%). Caregiver acceptance of monthly bNAb infusions was extremely high both pre-and post-intervention, with 21/24 (87.5%) preferring bNAbs to ART pre-intervention, and 21/25 (84%) preferring bNAbs post-intervention. While no caregiver preferred ART pre-intervention, 2/25 preferred it post-intervention. Pre-intervention, 3 (13%) caregivers had no preference between monthly bNAbs or daily ART, and 2 (8%) had no preference post-intervention. Pre-intervention, the most common reasons for preferring bNAbs over ART were the perception that bNAbs were better at suppressing the virus than ART (n = 10) and the fact that infusions were dosed once monthly compared to daily ART (n = 9). Post-intervention, no dominant reason for preferring bNAbs over ART emerged from caregivers., Conclusions: Monthly intravenous bNAb infusions were highly acceptable to caregivers of children with HIV in Botswana and preferred over standard ART by the majority of caregivers., Clinical Trial Number: NCT03707977., Competing Interests: The authors have declared that no competing interest exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Background: Isoniazid preventive therapy (IPT) is recommended for tuberculosis prevention yet data on the safety of first-trimester pregnancy exposure are limited., Methods: Planned secondary analysis in a TB prevention trial of adverse pregnancy outcomes among participants assigned to 9-month IPT who became pregnant during (IPT-exposed) or after (unexposed) IPT. Regression models compared binary outcomes of a composite adverse outcome (any non-live birth, excluding induced abortion); preterm delivery <37 weeks; and low birth weight <2500 g) among exposure groups. Models were adjusted for latent TB infection, maternal age, CD4 count, and antiretroviral therapy (ART)., Results: In total, 128 participants had a known pregnancy outcome; 39 IPT-exposed and 89 unexposed. At pregnancy outcome, ART use was lower in IPT-exposed (79%) than unexposed women (98%). Overall, 29 pregnancies ended in a composite adverse outcome (25 spontaneous abortions, 2 stillbirths and 2 ectopic pregnancies), 15 preterm deliveries, and 10 infants with low birth weight. IPT was associated with the composite adverse outcome adjusting for covariates at enrollment (adjusted relative risk [aRR] 1.98; 95% confidence interval [CI] 1.15, 3.41), but the effect was attenuated when adjusted for covariates at pregnancy outcome (aRR 1.47; 95% CI .84, 2.55); IPT was not associated with preterm delivery (relative risk [RR] 0.87; 95% CI .32-2.42) or low birth weight (RR 1.01; 95% CI .29, 3.56)., Conclusions: First-trimester IPT exposure was associated with nearly two-fold increased risk of fetal demise, mostly spontaneous abortion, though the association was attenuated when adjusted for covariates proximal to pregnancy outcome including ART use.

Background: Robust information on relative effects of hormonal contraceptives on endogenous androgens is important for understanding beneficial and adverse effects, method choice and development of new methods., Methods: In this ancillary study at the East London, South Africa site of the ECHO multicentre randomized trial, we compared effects of three contraceptive methods on serum androgen levels among contraceptive users aged 18 to 35 years. Participants were allocated by centrally-managed randomization to open label depot medroxyprogesterone acetate (DMPA-IM), copper intrauterine device (IUD) or levonorgestrel implant. The primary outcome was free testosterone at 6 months., Results: We analysed stored baseline and 6-month serum samples in 398/615 participants (DMPA-IM 131/205, IUD 135/205 and implant 132/205). Median testosterone levels at baseline were DMPA-IM 0.82, IUD 0.9 and implant 0.87 nmol/L; at 6 months, DMPA 0.68 (lower than IUD, mean percentage difference 28.35, (p <  0.001), IUD 0.86 (unchanged) and implant 0.66, lower than IUD, mean percentage difference - 22.98, p <  0.001). Median SHBG levels at baseline were DMPA 52.4, IUD 50.5 and implant 55.75 nmol/L; at 6 months, DMPA 40.65, lower than IUD (mean percentage difference 21.19, p = 0.005), IUD 49.1 (unchanged), and implant 23.35 nmol/L, lower than IUD (mean percentage difference - 50.04, p <  0.001 and than DMPA (mean percentage difference - 39.45, p <  0.001). Free testosterone levels at baseline were DMPA 10, IUD 12 and implant 11 pmol/L; at 6 months, DMPA 11, less than IUD (mean percentage difference 13.53, p = 0.047), IUD 12 and implant 14, higher than IUD (mean percentage difference 14.15, p = 0.038) and than DMPA, (mean percentage difference 29.60, p <  0.001)., Conclusions: This is the first randomized trial to show lower SHBG and higher free testosterone with the levonorgestrel implant than with DMPA, and contrasts with reports of increased SHBG with combined oral ethinyl estradiol/levonorgestrel use, and reduced androgens (and impaired sexual function) reported with the etonorgestrel implant. The higher free testosterone with the LNG implant might improve sexual function, mood and bone health as well as increasing side-effects such as acne and hirsutism, and is consistent with the greater sexual activity (with respect to multiple sex partners, new sex partner and unprotected sex) with the implant compared with DMPA documented in the ECHO study., Echo Trial Registration: ClinicalTrials.gov , number NCT02550067 15/09/2015. Contraception, or family planning, is central to the role of women in societies. It is most important to have accurate information on the relative side-effects of various contraceptive options in order to empower women to make informed choices regarding their preferred method. Hormonal contraceptives contain various forms of the female sex hormones, estrogens and/or progestogens. These hormones have direct effects on the users, as well as modifying the levels of the users' own circulating sex hormones, both the 'female' and the 'male' sex hormones (androgens). In this study, consenting participants requesting contraception, were allocated randomly to receive either depot medroxyprogesterone acetate (DMPA-IM) a 3-monthly progestogen injection, the copper intrauterine device (IUD), a non-hormonal contraceptive inserted within the womb, or the levonorgestrel implant, a device placed under the skin which releases a progestogen for 5 years. We measured the participants' androgen levels after 6 months, and found for the first time that the active form of testosterone (free testosterone) was 29% higher with the implant than with DMPA-IM. The level with the IUD was intermediate, and significantly different from the other two methods. This finding is relevant to the effects experienced by users of these methods, because free testosterone has effects on sexual function, bone health and mood, as well as on conditions such as acne and hair distribution patterns., (© 2024.

Background: Syphilis is a curable sexually transmitted infection that, untreated, is associated with significant morbidity and mortality. In people living with HIV (PLWH), syphilis carries greater risks of disease progression. We estimated syphilis prevalence among PLWH in the general population in sub-Saharan Africa and compared the prevalence among PLWH and without HIV., Methods: We searched for studies published January 1, 2011, to March 28, 2022, reporting syphilis prevalence among PLWH in sub-Saharan Africa (PROSPERO No. CRD42020167328). We excluded studies in high-risk subpopulations. We estimated pooled syphilis prevalence among PLWH using random-effects modeling and compared the prevalence with people without HIV when included in the same study. We examined influences of region, study setting, and test type in subgroup analyses., Results: We identified 926 studies; 53 were included in the meta-analysis. Pooled syphilis prevalence among PLWH was 7.3% (95% confidence interval [CI], 6.3%-8.5%). Prevalence differed by region: 3.1% (95% CI, 2.2%-4.0%) in Southern, 5.5% (95% CI, 2.3%-9.3%) in West/Central, and 10.5% (95% CI, 8.0%-13.1%) in Eastern Africa. Prevalence also differed by study setting: 13.8% (95% CI, 5.7%-23.0%) in sexual and reproductive health/sexually transmitted infection care, 8.7% (95% CI, 5.0%-12.8%) in HIV care, 7.1% (95% CI, 5.8%-8.5%) in antenatal care, and 3.8% (95% CI, 2.0%-5.8%) in household/community-based settings. Syphilis prevalence was higher among PLWH than without HIV (relative risk, 3.5; 95% CI, 2.8-4.5)., Conclusions: Syphilis is highly prevalent among PLWH in sub-Saharan Africa and is more common among PLWH than without HIV. Integration of syphilis screening and management into HIV care may reduce complications of HIV-syphilis coinfection among PLWH in sub-Saharan Africa., Competing Interests: Conflict of Interest and Sources of Funding: J.J. has received in-kind research support from binx health.

Introduction: Central nervous system infections (CNSI) disproportionately affect individuals in low-resource settings where diagnosis is challenging; large proportions of patients never receive a confirmed microbiological diagnosis resulting in inadequate management and high mortality. The epidemiology of CNSI varies globally and conventional diagnostics deployed in resource-limited settings have significant limitations, with an urgent need for improved diagnostic strategies., Areas Covered: This review describes molecular platforms and other novel diagnostics used in the diagnosis of CNSI that are applicable to resource-limited settings. An extensive literature search of Medline and PubMed was performed. The emphasis is on investigations targeting infections of relevance to resource-limited settings either due to variation in regional CNSI epidemiology or due to increased prevalence in patients with immunosuppression. This includes commercially available multiplex PCR platforms, mycobacterial PCR platforms, and rapid diagnostics tests. To offer a framework for the optimal implementation in clinical settings, existing evidence highlighting the advantages and limitations of available platforms is reviewed., Expert Opinion: The implementation of molecular platforms and other novel diagnostics has the potential to transform CNSI diagnosis in resource-limited settings, with several examples of successful rollout of novel diagnostics such as Xpert MTB/RIF Ultra and cryptococcal antigen testing.

Background: Approximately 30,000 non-citizens are living with HIV in Botswana, all of whom as of 2020 are eligible to receive free antiretroviral treatment (ART) within the country. We assessed the prevalence of HIV-1 mutational profiles [pre-treatment drug resistance (PDR) and acquired drug resistance (ADR)] among treatment-experienced (TE) and treatment-naïve (TN) non-citizens living with HIV in Botswana., Methods: A total of 152 non-citizens living with HIV were enrolled from a migrant HIV clinic at Independence Surgery, a private practice in Botswana from 2019-2021. Viral RNA isolated from plasma samples were genotyped for HIV drug resistance (HIVDR) using Sanger sequencing. Major known HIV drug resistance mutations (DRMs) in the pol region were determined using the Stanford HIV Drug Resistance Database. The proportions of HIV DRMs amongst TE and TN non-citizens were estimated with 95% confidence intervals (95% CI) and compared between the two groups., Results: A total of 60/152 (39.5%) participants had a detectable viral load (VL) >40 copies/mL and these were included in the subsequent analyses. The median age at enrollment was 43 years (Q1, Q3: 38-48). Among individuals with VL > 40 copies/mL, 60% (36/60) were treatment-experienced with 53% (19/36) of them on Atripla. Genotyping had a 62% (37/60) success rate - 24 were TE, and 13 were TN. A total of 29 participants (78.4, 95% CI: 0.12-0.35) had major HIV DRMs, including at least one non-nucleoside reverse transcriptase inhibitor (NNRTI) associated DRM. In TE individuals, ADR to any antiretroviral drug was 83.3% (20/24), while for PDR was 69.2% (9/13). The most frequent DRMs were nucleoside reverse transcriptase inhibitors (NRTIs) M184V (62.1%, 18/29), NNRTIs V106M (41.4%, 12/29), and K103N (34.4%, 10/29). No integrase strand transfer inhibitor-associated DRMs were reported., Conclusion: We report high rates of PDR and ADR in ART-experienced and ART-naïve non-citizens, respectively, in Botswana. Given the uncertainty of time of HIV acquisition and treatment adherence levels in this population, routine HIV-1C VL monitoring coupled with HIVDR genotyping is crucial for long-term ART success., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Mokgethi, Choga, Maruapula, Moraka, Seatla, Bareng, Ditshwanelo, Mulenga, Mohammed, Kaumba, Chihungwa, Marukutira, Moyo, Koofhethile, Dickinson, Mpoloka and Gaseitsiwe.)

Objectives: We sought to determine hepatitis B surface antigen (HBsAg) loss and its predictors among people with chronic hepatitis B (CHB) infections and HIV (PWH) in Botswana., Methods: Archived plasma samples from a cohort of PWH in Botswana (2013-2018) with 3 yearly time-points were used. Samples were screened for HBsAg, immunoglobulin M HBV core antibodies (anti-HBc IgM) and HBV e-antigen (HBeAg) at all time points. HBV deoxyribonucleic acid (DNA) quantification was done at baseline. The Wilcoxon rank-sum was used to compare continuous variables while the chi-squared test and Fishers exact test were used for categorical data wherever appropriate. Logistic regression was used to assess predictors of seroclearance., Results: Of 141 participants with HBsAg-positive serology (HBsAg+) at baseline, 92.2% (131/141) [95% confidence interval (CI) 87.4-96.1] were persistently HBsAg+ at year 1. We report a HBsAg loss of 7.1% (10/141) (95% CI 3.9-12.6) among participants with negative HBeAg and negative IgM serologies. HBsAg loss was 6.3% (7/111) among antiretroviral therapy (ART)-experienced participants and 10.7% (3/28) (95% CI 0.4-5.0) in ART-naive participants. Most participants who had positive anti-HBc IgM serology and did not lose HBsAg were on either lamivudine (3TC)-based therapy or non-tenofovir disoproxil fumarate (TDF)-based therapy, except for one participant. The participants also had varying HBeAg status. HBsAg loss was independent of HIV viral load, CD4 + cell count, age, and sex., Conclusion: We report a HBsAg loss of 6.3% over a 3-year period among ART-experienced CHB participants. Future studies that focus on HBsAg loss in mono-infected patients and the possible correlation between HBeAg status and HBsAg loss are warranted., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Morbidity and mortality due to cardiovascular diseases (CVDs) are high and increasing in low- and middle-income countries. People living with HIV (PLWH) are more likely to experience CVD than members of the general population. Therefore, we aimed to assess whether PLWH were more likely to have previously been screened for cardiovascular disease risk factors (CVDRFs) than people without HIV., Methods: A population-based, cross-sectional study was conducted among individuals aged 16 to 68 years across 22 communities in Botswana from February to August 2017 as part of a larger community-based cluster randomized HIV treatment-as-prevention trial. Participants were asked if they had been screened for and counselled on cardiovascular disease risk factors (history of hypertension or blood pressure check, blood glucose and cholesterol measurements, weight check and weight control, tobacco smoking and cessation, alcohol use and physical activity) in the preceding 3 years. HIV testing was offered to those with an unknown HIV status. Multiple logistic regression analysis controlling for age and sex was used to assess the relationship between CVDRF screening and HIV status., Results: Of the 3981 participants enrolled, 2547 (64%) were female, and 1196 (30%) were PLWH (93% already on antiretroviral therapy [ART]). PLWH were more likely to report previous screening for diabetes (25% vs. 19%, p < 0.001), elevated cholesterol (17% vs. 12%, p < 0.001) and to have had their weight checked (76% vs. 55%, p < 0.001) than HIV-uninfected participants. PLWH were also more likely to have received counselling on salt intake (42% vs. 33%, p < 0.001), smoking cessation (66% vs. 46%, p < 0.001), weight control (38% vs. 29%, p < 0.001), physical activity (46% vs. 34%, p < 0.001) and alcohol consumption (35% vs. 23%, p < 0.001) than their HIV-uninfected counterparts. Overall, PLWH were more likely to have received screening for and/or counselling on CVDRFs (adjusted odds ratio 1.84, 95% CI: 1.46-2.32, p < 0.001)., Conclusion: PLWH were almost two times more likely to have been previously screened for CVDRFs than those without HIV, indicating a need for universal scale-up of integrated management and prevention of CVDs in the HIV-uninfected population., (© 2024.

Background: Mother-to-child transmission of syphilis remains high especially in the WHO AFRO region with a prevalence of 1.62%, resulting in a congenital syphilis rate of 1,119 per 100,000 live births. Elimination efforts can be supported by an understanding of the spatial and temporal changes in disease over time, which can identify priority areas for targeted interventions aimed at reducing transmission., Methods: We collated routine surveillance data from health facilities and covariate data from demographic and health surveys conducted in Malawi between 2014 and 2022. We fitted a Bayesian hierarchical mixed model with spatial and temporally structured random effects to model the district-level monthly counts of maternal syphilis notifications as a function of individual- and district-level predictors. We then generated district-level spatiotemporally explicit risk profiles to estimate the effect of individual- and district-level covariates on maternal syphilis notifications and to identify hotspot areas., Results: Overall, the national prevalence of maternal syphilis increased from 0.28% (95% CI: 0.27-0.29%) in 2014 to peaking in 2021 at 1.92% (95% CI: 1.89-1.96%). Between 2020 and 2022, there was a decline in prevalence, with the most significant decline seen in Zomba District (1.40, 95% CI: 1.12-1.66%). In regression models, a one percentage point increase in district-level antenatal HIV prevalence was associated with increased maternal syphilis (prevalence ratio [PR]: 1.15, 95% credible interval [CrI]: 1.10-1.21). There was also an increased prevalence of maternal syphilis associated with an increased district-level mean number of sex partners (PR: 1.05, 95% CrI: 0.80-1.37). The number of districts with a high prevalence of maternal syphilis also increased between 2014 and 2022, especially in the southern region, where most had a high probability (approaching 100%) of having high maternal syphilis (defined as relative risk >1 compared to the standard population of women aged 15-49 years) in 2022., Conclusion: Maternal syphilis prevalence in Malawi shows an increasing upward trend, with an estimated six times relative increase between 2014 and 2022 (0.28% to 1.73%) and strong associations with higher district-level HIV prevalence. Controlling syphilis depends on reaching vulnerable populations at the sub-national level, which may be disproportionately affected. Our findings support the move to integrate the elimination of mother-to-child transmission (EMTCT) of syphilis programs with existing prevention of mother-to-child transmission (PMTCT) of HIV programs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Chirombo, Majamanda, Gunsaru, Yosefe, Ozituosauka, Mchoma, Morroni, Chipeta, MacPherson and Freyne.)
