The prevalence of cervical abnormalities: Comparison of youth with perinatally acquired HIV and older women in Botswana.

Background: Cervical cancer burden and prevalence of precursor lesions is unknown among young women living with HIV in high prevalence settings. Current cervical cancer screening guidelines in resource-limited settings with high HIV prevalence typically exclude adolescents and young women. After observing two cases of advanced cervical cancer among young women with perinatally acquired HIV, a pilot screening programme was established in Botswana. Objectives: To compare the prevalence of cervical abnormalities in young women with perinatally acquired HIV with women aged 30-49 years, regardless of HIV status. Method: We conducted a cross-sectional study of 30-49-year-old women who had visual inspection with acetic acid screening through the Botswana public sector programme, and youth (aged 15-24 years) with perinatally acquired HIV, at a single referral site between 2016 and 2018. We describe the prevalence of cervical abnormalities in each group as well as the crude prevalence ratio. Results: The prevalence of cervical abnormalities in women 30-49 years of age was 10.9% (95% confidence interval [CI]: 10.4, 11.4), and 10.1% (95% CI: 4.7, 18.3) for youth. The crude prevalence ratio was 1.07 (95% CI: 0.58, 2.01). Conclusion: Inclusion of youth living with HIV in cervical cancer screening services should be considered in settings with a high prevalence of HIV and cervical cancer.

The barriers and facilitators of HIV-exposed infant testing as perceived by HIV-positive mothers in Botswana: A qualitative study.

BACKGROUND: Despite high rates of HIV testing and enrolment of HIV-positive pregnant women on antiretroviral therapy in Botswana, coverage for HIV-exposed infant (HEI) testing remains suboptimal. Many factors can contribute to suboptimal HEI testing rates, but they have seldom been thoroughly investigated in Botswana. Therefore, the aim of this study was to explore the experiences and perspectives of HIV-positive mothers on the barriers and facilitators of HEI testing to inform interventions to promote HEI testing in Botswana. METHODS: We conducted focus group discussions (FGDs) with HIV-positive mothers who gave birth in 2016 at the three largest public hospitals in Botswana. FGDs were held in Maun, Francistown, and Gaborone from September 2019 to March 2020. The maximum variation sampling method was used to select the participants using information that was abstracted from birth registers and other medical records at the study sites. Mothers were asked to describe their HEI testing experiences, what made it easy or difficult for them to return the HEI for testing, and what needs to be done to improve HEI testing in Botswana. A thematic approach was used to analyse the data. RESULTS: Fifteen FGDs with 142 mothers (aged 21-52 years) were held. Participants identified several facilitators to HEI testing, including a mother with adequate knowledge of PMTCT, intensive tracking of HEI by healthcare workers (HCWs), positive attitudes of HCWs toward clients, and social support from significant others. Staff shortages at health care facilities, frequent stock-outs of HIV test kits, fear of stigma, fear of positive test results for the child, and transportation challenges were identified as key barriers to HEI testing. Increasing staffing at healthcare facilities, having adequate supplies of HIV test kits, enhanced HEI tracking, easing access to HEI testing services in rural areas, and providing quality PMTCT education were among the proposed interventions to promote HEI testing. CONCLUSION: Optimizing HEI testing in Botswana will require multi-level interventions at the policy, health system, community, interpersonal, and individual levels.

Catalyzing clinical implementation of pharmacogenomics and personalized medicine interventions in Africa.

Pharmacogenomics is considered to be the low-hanging fruit in the tree of genomic medicine with numerous examples of its successful implementation in the clinic. In this perspective, we provide details about the potential clinical application of pharmacogenomics in African populations by using relevant drug cases and high-throughput genomics approaches; involving numerous countries and stakeholders; and most importantly exploiting the existing knowledge of respective large-scale initiatives. We emphasize on the necessity of constructing appropriate frameworks for government policies in African countries. We also provide input about different initiatives in the field of genomics medicine implementation in Africa, not only for their potential for synergy and collaboration among them, but also as models for replication in other regions worldwide, aiming for healthcare improvement.
