AbstractIntroductionIn Botswana, where almost all pregnant women known to have HIV receive antiretroviral therapy, a large proportion of vertical HIV transmission may occur among women with incident undiagnosed HIV infection during pregnancy. Botswana guidelines recommend repeat HIV testing every 3 months in pregnancy, with at least one test in the third trimester. We evaluated the rate of repeat HIV testing, calculated HIV incidence during pregnancy and estimated missed seroconversions.MethodsIn the Botswana Tsepamo Study, we abstracted HIV test dates and results from obstetric records of all women who delivered at maternity wards in 18 communities between 7th May 2017 and 20th August 2021. We defined seroconversion as an initial negative/indeterminate HIV test in pregnancy followed by a positive test during pregnancy/at delivery. The incidence rate (IR) of seroconversion was calculated among women with > = 2 known test dates. Missed seroconversions were estimated among women without a test in the third trimester by applying the IR to the time after the last HIV test until delivery.ResultsAmong 103,529 women delivering in the study period testing negative at the first test and with known conception and HIV test dates, 29,085 (28%) were tested in one trimester of pregnancy, 73,156 (71%) were tested in ≥ 2 trimesters of pregnancy and 9628 (9%) had a test in all trimesters. A total of 78,162 (75%) women had a third‐trimester test. There were 223 seroconversions (2.58/1000 pregnancies, 0.26%) among those with ≥ 2 known HIV test dates, yielding an IR of 0.69/100 person‐years. Among 25,289 women who did not have a test in the third trimester, we estimate approximately 58 seroconversions may have been missed during pregnancy due to a lack of repeat testing. Factors associated with seroconversion during pregnancy included younger age, less education and not being married.ConclusionsMore than two‐thirds of women had repeat HIV testing in pregnancy and HIV incidence was low. However, an estimated 21% of seroconversions in pregnancy were likely missed due to a lack of re‐testing. To reach the goal of zero new paediatric HIV infections, Botswana will need to intensify repeat HIV testing in the third trimester of pregnancy.

AbstractIntroductionYoung women in sub‐Saharan Africa are at particularly high risk of HIV acquisition. Recent shifts towards "test and treat" strategies have potential to reduce transmission in this age group but have not been widely studied outside of clinical trials. Using data from nationwide surveillance among pregnant women in Botswana, where a "test and treat" program was implemented in 2016, we describe trends in HIV prevalence over time and highlight opportunities for targeted prevention.MethodsThe Tsepamo study abstracted data from obstetric records of all women delivering at eight government hospitals in Botswana between 2015 and 2019, accounting for 45% of all births in the country (n = 120,755). We used a stratified analysis to identify prevalence trends and evaluated decreases in HIV prevalence over time using the Cochrane–Armitage test for linear trend. A multivariable logistic regression analysis was also performed to identify factors associated with declines in HIV prevalence.ResultsOverall HIV prevalence was 24.1% among 120,755 women who delivered during the study period. Prevalence differed by site of delivery, ranging from 16.1% to 28.2%, and increased markedly with age. Lower educational attainment (adjusted odds ratio [aOR] = 3.28; 95% confidence interval [CI] 3.07–3.50) and being unmarried (aOR = 1.98; 95% CI 1.88–2.08) were associated with HIV infection. HIV prevalence was 10.0% with a first pregnancy, 21.0% with a second and 39.2% with a third or greater (aOR = 2.20; for any prior pregnancy; 95% CI 2.10–2.29). The same age‐adjusted trends were seen when data were limited to women aged 15–24, with a two‐ to three‐fold increase in HIV prevalence between a first and third pregnancy. Prevalence decreased linearly during the 5‐year study period from 25.8% to 22.7% (p <0.001). Among age‐specific strata, the greatest absolute decline occurred in those aged 35–39, with an 8.7% absolute decrease in HIV prevalence from 2015 to 2019. Minimal declines were seen in those 15–24, with a decrease of only 1.5% over the same period.ConclusionsWhile overall trends in Botswana show HIV prevalence declining among pregnant women, prevalence among the youngest age group has remained stagnant. Preventative interventions utilizing pre‐exposure prophylaxis should be prioritized during the high‐risk period surrounding a woman's first pregnancy.

BACKGROUND: Women with vertically acquired HIV (VHIV) may have a greater risk of adverse birth outcomes than women with horizontally acquired HIV (HHIV). METHODS: The Tsepamo study performed birth outcomes surveillance at 8 government delivery sites in Botswana from July 2014 through March 2019. Pregnant women diagnosed with HIV before their 11th birthday received VHIV status, and other women had HHIV. Small for gestational age (SGA), preterm delivery (PTD), stillbirth, and neonatal death were compared using χ2 and Fisher's exact tests. Log-binomial regression models determined risk ratios (RRs). RESULTS: VHIV women (n = 402) aged 15–27 years were identified over 4 years of surveillance and compared with HHIV women (n = 8465) of the same age. VHIV women were more likely to use nevirapine (NVP)-based antiretroviral treatment (ART) in pregnancy and to have SGA and very SGA infants, but less likely to have very PTD infants. In unadjusted analyses, VHIV women had a higher risk of any adverse birth outcome combined (RR = 1.21, 95% confidence interval [CI], 1.08–1.36). After adjusting for potential confounders, particularly use of NVP-based regimens, the risk of adverse birth outcomes among VHIV and HHIV women was similar. CONCLUSIONS: NVP-based ART is a primary and modifiable risk factor for adverse birth outcomes. Updating ART regimens could improve birth outcomes for women with HIV.

AbstractIntroductionIn December 2019, the Botswana government expanded free antiretroviral therapy (ART) to include non‐citizens. We evaluated the impact of this policy change on antenatal care (ANC), antiretroviral therapy coverage and adverse birth outcomes.MethodsThe Tsepamo Surveillance study collects data at up to 18 delivery sites in Botswana. We compared outcomes in citizens and non‐citizens living with HIV before and after antiretroviral therapy expansion to non‐citizens. Adverse birth outcomes included preterm delivery (PTD) <37 weeks, very preterm delivery (VPTD) <32 weeks, small for gestational age (SGA) <10th percentile, very small for gestational age (VSGA) <3rd percentile, stillbirth and neonatal death. Log‐binomial regression models were constructed to generate risk ratios.ResultsFrom August 2014 to September 2021, 45,576 (96.5%) citizens and 1513 (3.2%) non‐citizens living with HIV delivered; 954 (62.9%) non‐citizen deliveries were before the antiretroviral therapy expansion, and 562 (37.1%) were after. Non‐citizen ANC attendance among pregnant people living with HIV increased from 79.2% pre‐expansion to 87.2% post‐expansion (p<0.001), and became more similar to citizens (96.0% post‐expansion). Non‐citizens receiving any antenatal antiretroviral therapy increased from 65.5% pre‐expansion to 89.9% post‐expansion (p < 0.001), also more similar to citizens (97.2% post‐expansion). Infants born to non‐citizens with singleton gestations in the pre‐expansion period had significantly greater risk of PTD (aRR = 1.28, 95% CI, 1.11, 1.46), VPTD (aRR = 1.89, 95% CI, 1.43, 2.44) and neonatal death (aRR = 1.69, 95% CI, 1.03, 2.60), but reduced SGA risk (aRR = 0.75; 95% CI, 0.62, 0.89) compared with citizens. Post‐expansion, greater declines in most adverse outcomes were observed in non‐citizens, with largely similar outcomes between non‐citizens and citizens. Non‐significant differences were observed for non‐citizenship in PTD (aRR = 0.84, 95% CI, 0.66, 1.06), VPTD (aRR = 0.57, 95% CI, 0.28, 1.01), SGA (aRR = 0.91, 95% CI, 0.72, 1.13), VSGA (aRR = 0.87, 95% CI, 0.58, 1.25), stillbirth (aRR = 0.71, 95% CI, 0.35, 1.27) and neonatal death (aRR = 1.35, 95% CI, 0.60, 2.62).ConclusionsFollowing the expansion of free antiretroviral therapy to non‐citizens, gaps narrowed in ANC and antiretroviral therapy use in pregnancy between citizens and non‐citizens living with HIV. Disparities in adverse birth outcomes were no longer observed.

OBJECTIVES: This study aims to evaluate the prevalence and outcome of twin pregnancies in Botswana. SETTING: The Tsepamo Study conducted birth outcomes surveillance at 8 government-run hospitals (~45% of all births in Botswana) from August 2014 to June 2018 and expanded to 18 hospitals (~70% of all births in Botswana) from July 2018 to March 2019. PARTICIPANTS: Data were collected for all live-born and stillborn in-hospital deliveries with a gestational age (GA) greater than 24 weeks. This analysis included 117 593 singleton and 3718 twin infants (1859 sets (1.6%)) born to 119 477 women between August 2014 and March 2019 and excluded 73 higher order multiples (23 sets of triplets and 1 set of quadruplets). OUTCOMES MEASURED: Our primary outcomes were preterm delivery (<37 weeks GA), very preterm delivery (<32 weeks GA) and stillbirth (APGAR (Appearance, Pulse, Grimace, Activity, Respiration) score of 0, 0, 0). RESULTS: Women with twin pregnancies had a similar median number of antenatal care visits (9 vs 10), but were more likely to deliver in a tertiary centre (54.8% vs 45.1%, p<0.001) and more likely to have a cesarean-section (54.6% vs 22.0%, p<0.001) than women with singletons. Compared with singletons, twin pregnancies had a higher risk of preterm delivery (<37 weeks GA) (47.6% vs 16.7%, adjusted risk ratio (aRR) 2.8, 95% CI 2.7 to 2.9) and very preterm delivery (<32 weeks) (11.8% vs 4.0%, aRR 3.0 95% CI 2.6 to 3.4). Among all twin pregnancies, 128 (6.9%) had at least one stillborn infant compared with 2845 (2.4%) stillbirths among singletons (aRR 2.8, 95% CI 2.3 to 3.3). CONCLUSION: Adverse birth outcomes are common among twins in Botswana, and are often severe. Interventions that allow for earlier identification of twin gestation and improved antenatal management of twin pregnancies may improve infant and child survival.

AbstractIntroductionAntiretroviral therapy (ART) has significantly improved survival in Africa in recent years. In Botswana, where adult HIV prevalence is 21.9%, AIDS‐related mortality is estimated to have declined by 58% between 2005 and 2013 following the initial wide‐spread introduction of ART, and ART coverage has steadily increased reaching 84% in 2016. However, there remains little data about the burden of HIV and its impact on mortality in the hospital setting where most deaths occur. We aimed to describe the burden of HIV and related morbidity and mortality among hospitalized medical patients in a district hospital in southern Botswana in the era of widespread ART coverage.MethodsWe prospectively reviewed medical admissions to Scottish Livingstone Hospital from December 2015 to November 2017 and recorded HIV status, demographics, clinical characteristics and final diagnoses at discharge, death or transfer. We ascertained outcomes and determined factors associated with mortality. Results were compared with similar surveillance data collected at the same facility in 2011 to 2012.ResultsA total of 2316 admissions occurred involving 1969 patients; 42.4% were of HIV‐positive patients, 46.9% of HIV‐negative patients and 10.7% of patients with unknown HIV status. Compared to HIV‐negative patients, HIV‐positive patients had younger age (mean 42 vs. 64 years, p < 0.0001) and higher mortality (22.2% vs. 18.0%, p = 0.03). Tuberculosis was the leading diagnosis among mortality cases in both groups but accounted for a higher proportion of deaths among HIV‐positive admissions (44.5%) compared with HIV‐negative admissions (19.4%, p < 0.0001). Compared with similar surveillance in 2011 to 2012, HIV prevalence was lower (42.4% vs. 47.6%, p < 0.01), and among HIV‐positive admissions: ART coverage was higher (72.2% vs. 56.2%, p < 0.0001), viral load suppression was similar (78.6% vs. 80.3%, p = 0.77), CD4 counts were higher (55.0% vs. 44.6% with CD4 ≥200 cells/mm3, p < 0.001), mortality was similar (22.2 vs. 22.7%, p = 0.93), tuberculosis diagnoses increased (27.5% vs. 20.1%, p < 0.01) and tuberculosis‐associated mortality was higher (35.9% vs. 24.7%, p = 0.05).ConclusionsDespite high ART‐coverage in Botswana, HIV‐positive patients continue to be disproportionately represented among hospital admissions and deaths. Deaths from tuberculosis may be contributing to lack of reduction in inpatient mortality. Our findings suggest that control of HIV and tuberculosis remain top priorities for reducing inpatient mortality in Botswana.

BackgroundAbacavir (ABC) may be associated with a small, increased risk of myocardial infarction in HIV‐infected adults, possibly related to cytokine‐mediated inflammation.MethodsTo evaluate the induction of inflammatory cytokine transcription by ABC, we used samples from women randomized to receive zidovudine/lamivudine/ABC (Trizivir) or lopinavir/ritonavir and zidovudine/lamividine (Kaletra/Combivir) from the third trimester through six‐months postpartum for the prevention of mother‐to‐child transmission (PMTCT). Women were matched by CD4 count and baseline HIV RNA. All women attained viral suppression (<50 copies/ml) by the time of sampling.ResultsFour cytokines showed a difference in expression between the treatment arms, all in a proinflammatory direction for the ABC arm: CD40LG 1.82‐fold, (p=.027); IL‐8 3.16‐fold (p=.020); LTA 2.82‐fold, (p=.008); and CCL5 −1.67‐fold, (p=.035). At 12‐months postpartum, 6‐months after antiretroviral discontinuation, cytokine expression was similar by treatment arm.ConclusionsWe conclude that ABC may upregulate proinflammatory cytokines at the transcriptional level in this population.

BACKGROUND: Adolescent girls are three times more likely to be living with HIV than boys of the same age. Prior studies have found associations between adolescent pregnancies and increased maternal morbidity and infant mortality, but few studies have assessed the impact of HIV infection on maternal and infant outcomes in adolescents. METHODS: The Tsepamo Study abstracts maternal and infant data from obstetric records in government maternity wards in Botswana. We assessed maternal complications and adverse birth outcomes for all singleton pregnancies from August 2014 to August 2020 at eighteen Tsepamo sites among adolescents (defined as 10–19 years of age) and adults (defined as 20–35 years of age), by HIV status. Univariate and multivariate logistic regression using a complete case analysis method were used to evaluate differences in outcomes. RESULTS: This analysis included 142,258 singleton births, 21,133 (14.9%) to adolescents and 121,125 (85.1%) to adults. The proportion of adults living with HIV (N = 22,114, 22.5%) was higher than adolescents (N = 1593, 7.6%). The proportion of most adverse birth outcomes was higher in adolescents. Among adolescents, those with HIV had increased likelihoods of anemia (aOR = 1.89, 95%CI 1.66, 2.15) and cesarean sections (aOR = 1.49, 95%CI 1.3,1.72), and infants with preterm birth (aOR = 1.15, 95%CI 1.0, 1.32), very preterm birth (aOR = 1.35, 95%CI 1.0,1.8), small for gestational age (aOR = 1.37, 95%CI 1.20,1.58), and very small for gestational age (aOR = 1.46, 95%CI 1.20, 1.79). CONCLUSIONS: Adolescent pregnancy and adolescent HIV infection remain high in Botswana. Adolescents have higher risk of adverse maternal and infant birth outcomes than adults, with the worst outcomes among adolescents living with HIV. Linking HIV prevention and family planning strategies for this age group may help minimize the number of infants with poor birth outcomes among this already vulnerable population.

BACKGROUND: Botswana updated its antiretroviral treatment (ART) guidelines in May 2016 to support breastfeeding for women living with HIV (WLHIV) on ART who have documented HIV RNA suppression during pregnancy. METHODS: From September 2016 to March 2019, we evaluated feeding method at discharge among WLHIV at eight government maternity wards in Botswana within the Tsepamo Study. We validated the recorded feeding method on the obstetric record using the prevention of mother-to-child transmission of HIV (PMTCT) counsellor report, infant formula dispensing log or through direct observation. Available HIV RNA results were recorded from the obstetric record, and from outpatient HIV records (starting February 2018). In a subset of participants, we used electronic laboratory records to verify whether an HIV RNA test had occurred. Univariable and multivariable logistic regression analyses were performed to identify factors associated with infant feeding choice. RESULTS: Among 13,354 WLHIV who had a validated feeding method at discharge, 5303 (39.7%) chose to breastfeed and 8051 (60.3%) chose to formula feed. Women who had a documented HIV RNA result in the obstetric record available to healthcare providers at delivery were more likely to breastfeed (50.8%) compared to women who did not have a documented HIV RNA result (35.4%) (aOR 0.59; 95% CI 0.54, 0.65). Among women with documented HIV RNA, 2711 (94.6%) were virally suppressed ( 400 copies/mL, and 134 (27.4%) of 489 women with no reported ART use. A sub-analysis of electronic laboratory records among 150 women without a recorded result on the obstetric record revealed that 93 (62%) women had an HIV RNA test during pregnancy. CONCLUSIONS: In a setting of long-standing use of suppressive ART, with majority of WLHIV on ART from the time of conception, requiring documentation of HIV RNA suppression in the obstetric ...

BACKGROUND: Vaginal discharge syndrome (VDS) is a common clinical diagnosis during pregnancy in Botswana; it is treated with broad-spectrum antibiotics using a syndromic approach. We evaluated associations between the syndromic management of VDS and adverse birth outcomes. METHODS: The Tsepamo Study performs birth outcomes surveillance at government hospitals throughout Botswana. Obstetric record data collected from August 2014 to March 2019 were analyzed. Chi-square tests were conducted to compare proportions of maternal characteristics and infant outcomes. To avoid immortal time bias, all analyses were conducted among women who presented to care before 24 weeks gestation, with VDS categorized as present or absent by 24 weeks gestation. Log-binomial regression models were generated to determine associations between treated VDS and infant outcomes. RESULTS: VDS was diagnosed in 36 731 (30.7%) pregnant women, of whom 33 328 (90.7%) received antibiotics. Adjusted analyses yielded a harmful association between treated VDS and very preterm delivery (adjusted risk ratio, 1.11; 95% CI, 1.02–1.21). This association remained when restricting to women with VDS who received the recommended antibiotic treatment regimen. Sensitivity analyses produced nonsignificant associations when women with treated VDS were compared with women without VDS who received antibiotics for other indications. CONCLUSIONS: A clinical diagnosis of VDS is common among pregnant women in Botswana, and the majority receive antibiotics in pregnancy. Although analyses of VDS occurring later in pregnancy are precluded by immortal time bias, a modest association between treated VDS and very preterm delivery was observed among women diagnosed with VDS by 24 weeks gestation.

IntroductionIt would be useful to understand which populations are not reached by home‐based HIV‐1 testing and counselling (HTC) to improve strategies aimed at linking these individuals to care and reducing rates of onward HIV transmission.MethodsWe present the results of a baseline home‐based HTC (HBHTC) campaign aimed at counselling and testing residents aged 16 to 64 for HIV in the north‐eastern sector of Mochudi, a community in Botswana with about 44,000 inhabitants. Collected data were compared with population references for Botswana, the United Nations (UN) estimates based on the National Census data and the Botswana AIDS Impact Survey IV (BAIS‐IV). Analyzed data and references were stratified by age and gender.ResultsA total of 6238 age‐eligible residents were tested for HIV‐1; 1247 (20.0%; 95% CI 19.0 to 21.0%) were found to be HIV positive (23.7% of women vs. 13.4% of men). HIV‐1 prevalence peaked at 44% in 35‐ to 39‐year‐old women and 32% in 40‐ to 44‐year‐old men. A lower HIV prevalence rate, 10.9% (95% CI 9.5 to 12.5%), was found among individuals tested for the first time. A significant gender gap was evident in all analyzed subsets. The existing HIV transmission network was analyzed by combining phylogenetic mapping and household structure. Between 62.4 and 71.8% of all HIV‐positive individuals had detectable virus. When compared with the UN and BAIS‐IV estimates, the proportion of men missed by the testing campaign (48.5%; 95% CI 47.0 to 50.0%) was significantly higher than the proportion of missed women (14.2%; 95% CI 13.2 to 15.3%;p<0.0001). The estimated proportion of missed men peaked at about 60% in the age group 30 to 39 years old. The proportions of missed women were substantially smaller, at approximately 28% within the age groups 30 to 34 and 45 to 49 years old.ConclusionsThe HBHTC campaign seems to be an efficient tool for reaching individuals who have never been tested previously in southern African communities. However, about half of men from 16 to 64 years old were not reached by the HBHTC, including about 60% of men between 30 and 40 years old. Alternative HTC strategies should be developed to bring these men to care, which will contribute to reduction of HIV incidence in communities.

AbstractIntroductionDespite declining risk of vertical HIV transmission, prophylactic cotrimoxazole (CTX) remains widely used to reduce morbidity and mortality in the event of HIV infection among exposed infants, with an inherent risk of conferring commensal antimicrobial resistance. Using data from a randomized, placebo‐controlled trial of infant CTX prophylaxis, we sought to quantify emergence of antibiotic resistance.MethodsHIV‐exposed uninfected infants enrolled in the Botswana Mpepu study were randomized to prophylactic CTX or placebo between 14 and 34 days of life and continued through 15 months. Stool samples were collected from a subset of participating infants at randomization, three, and six months, and stored at −70°C prior to culture. Specimens that grew Escherichia coli (E. coli) or Klebsiella species (Klebsiella spp.) underwent antibiotic susceptibility testing by Kirby Bauer method using CTX (CTX 1.25/23.75 μg) and Amoxicillin (10 μg) in Mueller Hinton agar. Fisher's exact testing was used to compare prevalence of resistance by randomization arm (CTX/placebo).Results and DiscussionA total of 381 stool samples from 220 infants were cultured: 118 at randomization, 151 at three months, and 112 at six‐months. E. coli was isolated from 206 specimens and Klebsiella spp. from 138 specimens. Resistance to CTX was common in both E. coli and Klebsiella spp. at the randomization visit (52.2% and 37.7% respectively) and did not differ by study arm. E. Coli isolates from CTX recipients at three and six months had 94.9% and 84.2% CTX resistance, as compared with 51.4% and 57.5% CTX resistance in isolates from placebo recipients (p=0.01). Klebsiella spp. isolates from CTX recipients had 79.0% and 68.8% CTX resistance at three and six months, as compared with 19.1% and 14.3% in isolates from placebo recipients (p<0.01).ConclusionsHIV‐exposed infants randomized to CTX prophylaxis had increased CTX‐resistant commensal gastrointestinal bacteria compared with placebo recipients. Additional research is needed to determine the longer‐term clinical, microbiologic, and public health consequences of antimicrobial resistance selected by infant CTX prophylaxis.

There is a global cancer crisis, and it is disproportionately affecting resource-constrained settings, especially in low- and middle-income countries (LMICs). Radiotherapy is a critical and cost-effective component of a comprehensive cancer control plan that offers the potential for cure, control, and palliation of disease in greater than 50% of patients with cancer. Globally, LMICs do not have adequate access to quality radiation therapy and this gap is particularly pronounced in sub-Saharan Africa. Although there are numerous challenges in implementing a radiation therapy program in a low-resource setting, providing more equitable global access to radiotherapy is a responsibility and investment worth prioritizing. We outline a systems approach and a series of key questions to direct strategy toward establishing quality radiation services in LMICs, and highlight the story of private-public investment in Botswana from the late 1990s to the present. After assessing the need and defining the value of radiation, we explore core investments required, barriers that need to be overcome, and assets that can be leveraged to establish a radiation program. Considerations addressed include infrastructure; machine choice; quality assurance and patient safety; acquisition, development, and retention of human capital; governmental engagement; public–private partnerships; international collaborations; and the need to critically evaluate the program to foster further growth and sustainability.
