Abstract
INTRODUCTION A lower adherence rate (percentage of individuals taking drugs as prescribed) to ART may increase the risk of emergence and transmission of HIV drug resistance, decrease treatment efficacy, and increase mortality rate. Exploring the impact of ART adherence on the transmission of drug resistance could provide insights in controlling the HIV epidemic. METHODS We proposed a dynamic transmission model incorporating the CD4 cell count-dependent rates of diagnosis, treatment and adherence with transmitted drug resistance (TDR) and acquired drug resistance. This model was calibrated and validated by 2008-2018 HIV/AIDS surveillance data and prevalence of TDR among newly diagnosed treatment-naive individuals from Guangxi, China, respectively. We aimed to identify the impact of adherence on drug resistance and deaths during expanding ART. RESULTS In the base case (ART at 90% adherence and 79% coverage), we projected the cumulative total new infections, new drug-resistant infections, and HIV-related deaths between 2022 and 2050 would be 420 539, 34 751 and 321 671. Increasing coverage to 95% would reduce the above total new infections (deaths) by 18.85% (15.75%). Reducing adherence to below 57.08% (40.84%) would offset these benefits of increasing coverage to 95% in reducing infections (deaths). Every 10% decrease in adherence would need 5.07% (3.62%) increase in coverage to avoid an increase in infections (deaths). Increasing coverage to 95% with 90% (80%) adherence would increase the above drug-resistant infections by 11.66% (32.98%). CONCLUSIONS A decrease in adherence might offset the benefits of ART expansion and exacerbate the transmission of drug resistance. Ensuring treated patients' adherence might be as important as expanding ART to untreated individuals.

Abstract
The Namibia national antiretroviral therapy guidelines recommend that patients living with HIV who interrupt antiretrovirals and in the process disengage from care be restarted on their usual antiretroviral therapy regimen upon return. We introduce a 39-year-old male patient on first-line antiretroviral therapy, namely, tenofovir disoproxil fumarate, lamivudine and efavirenz, from 2015 to 2019 (4 years), who returned to care after the fourth episode of interrupting his treatment, though his adherence to antiretroviral therapy was deemed poor. Thus, he presented with severe immunosuppression and an AIDS-defining condition. Hence, he was switched to second-line antiretroviral therapy, treated with fluconazole for oesophageal candidiasis and reinitiated on cotrimoxazole prophylaxis. The client is currently clinically stable with a suppressed viral load. Medical and drug history taking with an emphasis on the previous history of treatment failure in patients returning to care are paramount in guiding the choice of future prescriptions of antiretrovirals. The multiple antiretroviral therapy interruptions from the patient and the delay in decision-making on the side of the clinician to switch treatments contributed to the emergence of an AIDS-defining condition.

Abstract
Background Stigmatization and poor social support are challenges faced by individuals living with HIV or sexually transmitted disease, which can have a profound negative impact on their healthcare. Mother-to-child transmission of either HIV or syphilis can lead to adverse maternal and fetal outcomes. The aim of this study was to investigate stigmatization and social support of pregnant women with HIV or syphilis in eastern China. Methods This was an explanatory sequential mixed-method study conducted in Zhejiang province, China in 2019. Stigmatization, social support, and the associated factors toward HIV or syphilis were evaluated using questionnaires. The social support rating scale was used to evaluate social support, where a score <25% was defined as poor social support. A logistic regression model was used to explore the association between stigmatization and poor social support. Results A total of 448 women (HIV positive, N = 93; syphilis, N = 355) were recruited in this study. Higher stigmatization was observed in pregnant women with HIV compared to those with syphilis (53.76% vs. 24.36%, p < 0.001), and poorer social support was observed in women with HIV compared with those with syphilis (40.86% vs. 19.86%, p < 0.001), with significant distributions of the total social support scores (Z = −1.976, p = 0.048) and scores on objectivity (Z = −2.036, p = 0.042) and subjectivity (Z = −2.500, p = 0.012). Similar social support among HIV or syphilis pregnant women was observed in medical healthcare facilities. In multivariable logistic model analysis, stigmatization (ORadj = 2.927; 95%CI, 1.714–4.996; p < 0.001) and ethnic minority (ORadj = 2.373; 95%CI, 1.113–5.056; p = 0.025) were negatively associated with social support. Interestingly, employment status was associated with improved social support (ORadj = 0.345; 95%CI, 0.180–0.662; p = 0.001). Conclusion Stigmatization among pregnant women with HIV or syphilis remains high. We demonstrated that stigmatization was a significant predictor of low social support in pregnant women with HIV or syphilis. The support shown in medical facilities was similar toward pregnant women with HIV or syphilis. Implementation of stigmatization eradication and social support strategies targeting pregnant women with HIV or syphilis may therefore improve the dual elimination of mother-to-child transmission service.

Abstract
HIV stigma is a major barrier to HIV care and treatment among people living with HIV (PLWH). Evidence suggests that expansion in antiretroviral therapy (ART) may reduce stigma. However, there are limited longitudinal studies examining temporal trends in HIV stigma in sub-Saharan Africa in the Undetectable = Untransmittable (U = U) era. We longitudinally assessed temporal trends in self-reported experienced stigma and the association of experienced stigma with ART adherence and viral suppression among PLWH enrolled in the African Cohort Study (AFRICOS). AFRICOS is an ongoing cohort study enrolling PLWH in Uganda, Kenya, Tanzania, and Nigeria. As of 1 March 2020, 2937 PLWH enrolled in AFRICOS and had available data. In 2013, 22% of participants reported stigma at the enrollment visit and by 2018 the prevalence decreased to 1% overall and was below 2% for all countries. However, there was not a statistically significant change in stigma prevalence in our longitudinal models. In adjusted models, experiencing stigma was associated with a 0.67 decreased odds of ART Adherence (95% confidence interval (CI): 0.56-0.80) and a 0.64 decreased odds of viral suppression (95% CI: 0.73-0.99). HIV-associated stigma was associated with poor self-reported ART adherence and unsuppressed viral load.
