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.

"We did not know what was wrong"-Barriers along the care cascade among hospitalized adolescents with HIV in Gaborone, Botswana.

High mortality among adolescents with HIV reflects delays and failures in the care cascade. We sought to elucidate critical missed opportunities and barriers to care among adolescents hospitalized with HIV at Botswana's tertiary referral hospital. We enrolled all HIV-infected adolescents (aged 10-19 years) hospitalized with any diagnosis other than pregnancy from July 2015 to January 2016. Medical records were reviewed for clinical variables and past engagement in care. Semi-structured interviews of the adolescents (when feasible) and their caregivers explored delays and barriers to care. Twenty-one eligible adolescents were identified and 15 were enrolled. All but one were WHO Clinical Stage 3 or 4. Barriers to diagnosis included lack of awareness about perinatal HIV infection, illness or death of the mother, and fear of discrimination. Barriers to adherence to antiretroviral therapy included nondisclosure, isolation, and mental health concerns. The number of hospitalized HIV-infected adolescents was lower than expected. However, among those hospitalized, the lack of timely diagnosis and subsequent gaps in the care cascade elucidated opportunities to improve outcomes and quality of life for this vulnerable group.

The adherence-outcome relationship is not altered by diary-driven adjustments of microelectronic monitor data.

PURPOSE: The purpose of this study was to determine whether diary-driven adjustment of Medication Event Monitoring System (MEMS) data based on Supporting Information strengthens the relationship between measured antiretroviral medication adherence and plasma HIV viral load (VL). METHODS: HIV+ adolescents on antiretroviral treatment were monitored with MEMS for 30 days preceding a VL measurement. The primary outcome was VL ≥ 400 copies/mL. Handwritten diaries were used to comprehensively record deviations from recommended use (bottle opened but dose not taken or bottle not opened and dose taken). Data were adjusted ("cleaned") based on diary events. Data were "capped" at the prescribed number of doses/day. Receiver operator characteristic analysis compared the relationships between (i) raw MEMS data, (ii) diary-cleaned, (iii) capped, or (iv) cleaned and capped MEMS data and VL. RESULTS: Over 30 days preceding VL measurements, 273 adolescents had 465 diary events. Capping resulted in fewer patients classified as 95% adherent (65.2%) compared with raw data (71.4%), p < 0.001. Adherence was highly associated with VL (OR 1.05, p < 0.001). The area under the receiver operating characteristic curve for continuous adherence compared with VL was 0.89 (95%CI: 0.82-0.95). Neither diary-cleaning, capping, nor cleaning and capping MEMS data significantly altered the association between adherence and VL (p = 0.14, 0.40, and 0.19, respectively). CONCLUSION: Medication Event Monitoring System data-cleaning based on diary entries did not affect the adherence-VL relationship.

Psychosocial assessments for HIV+ African adolescents: establishing construct validity and exploring under-appreciated correlates of adherence.

STUDY OBJECTIVES: Psychosocial factors such as outcome expectancy, perceived stigma, socio-emotional support, consideration of future consequences, and psychological reactance likely influence adolescent adherence to antiretroviral treatments. Culturally-adapted and validated tools for measuring these factors in African adolescents are lacking. We aimed to identify culturally-specific factors of importance to establishing local construct validity in Botswana. METHODS: Using in-depth interviews of 34 HIV+ adolescents, we explored how the psychosocial factors listed above are perceived in this cultural context. We evaluated six scales that have been validated in other contexts. We also probed for additional factors that the adolescents considered important to their HIV medication adherence. Analyses were conducted with an analytic framework approach using NVivo9 software. RESULTS: While the construct validity of some Western-derived assessment tools was confirmed, other tools were poorly representative of their constructs in this cultural context. Tools chosen to evaluate HIV-related outcome expectancy and perceived stigma were well-understood and relevant to the adolescents. Feedback from the adolescents suggested that tools to measure all other constructs need major modifications to obtain construct validity in Botswana. The scale regarding future consequences was poorly understood and contained several items that lacked relevance for the Batswana adolescents. They thought psychological reactance played an important role in adherence, but did not relate well to many components of the reactance scale. Measurement of socio-emotional support needs to focus on the adolescent-parent relationship, rather than peer-support in this cultural context. Denial of being HIV-infected was an unexpectedly common theme. Ambivalence about taking medicines was also expressed. DISCUSSION: In-depth interviews of Batswana adolescents confirmed the construct validity of some Western-developed psychosocial assessment tools, but demonstrated limitations in others. Previously underappreciated factors related to HIV medication adherence, such as denial and ambivalence, should be further explored.
