Antiretroviral treatment interruption among people living with HIV during COVID-19 outbreak in China: a nationwide cross-sectional study.

INTRODUCTION: Social disruption associated with coronavirus disease 2019 (COVID-19) threatens to impede access to regular healthcare, including for people living with HIV (PLHIV), potentially resulting in antiretroviral therapy (ART) interruption (ATI). We aimed to explore the characteristics and factors associated with ATI during the COVID-19 outbreak in China. METHODS: We conducted an online survey among PLHIV by convenience sampling through social media between 5 and 17 February 2020. Respondents were asked to report whether they were at risk of ATI (i.e. experienced ATI, risk of imminent ATI, threatened but resolved risk of ATI [obtaining ART prior to interruption]) or were not at risk of ATI associated with the COVID-19 outbreak. PLHIV were also asked to report perceived risk factors for ATI and sources of additional ART. The factors associated with the risk of ATI were assessed using logistic regression. We also evaluated the factors associated with experienced ATI. RESULTS: A total of 5084 PLHIV from 31 provinces, autonomous regions and municipalities in mainland China completed the survey, with valid response rate of 99.4%. The median age was 31 years (IQR 27 to 37), 96.5% of participants were men, and 71.3% were men who had sex with men. Over one-third (35.1%, 1782/5084) reported any risk of ATI during the COVID-19 outbreak, including 2.7% (135/5084) who experienced ATI, 18.0% (917/5084) at risk of imminent ATI and 14.4% (730/5084) at threatened but resolved risk. PLHIV with ATI were more likely to have previous interruptions in ART (aOR 8.3, 95% CI 5.6 to 12.3), travelled away from where they typically receive HIV care (aOR 3.0, 95% CI 2.1 to 4.5), stayed in an area that implemented citywide lockdowns or travel restrictions to control COVID-19 (aOR 2.5, 95% CI 1.4 to 4.6), and be in permanent residence in a rural area (aOR 3.7, 95% CI 2.3 to 5.8). CONCLUSIONS: A significant proportion of PLHIV in China are at risk of ATI during the COVID-19 outbreak and some have already experienced ATI. Correlates of ATI and self-reported barriers to ART suggest that social disruptions from COVID-19 have contributed to ATI. Our findings demonstrate an urgent need for policies and interventions to maintain access to HIV care during public health emergencies.

Lessons Learned From Option B+ in the Evolution Toward "Test and Start" From Malawi, Cameroon, and the United Republic of Tanzania.

The acceleration of prevention of mother-to-child transmission (PMTCT) activities, coupled with the rollout of 2010 World Health Organization (WHO) guidelines, led to important discussions and innovations at global and country levels. One paradigm-shifting innovation was Option B+ in Malawi. It was later included in WHO guidelines and eventually adopted by all 22 Global Plan priority countries. This article presents Malawi's experience with designing and implementing Option B+ and provides complementary narratives from Cameroon and Tanzania. Malawi's HIV program started in 2002, but by 2009, the PMTCT program was lagging far behind the antiretroviral therapy (ART) program because of numerous health system challenges. When WHO recommended Option A and Option B for PMTCT in 2010, it was clear that Malawi's HIV program would not be able to successfully implement either option without increasing existing barriers to PMTCT services and potentially decreasing women's access to care. Subsequent stakeholder discussions led to the development of Option B+. Operationalizing Option B+ required several critical considerations, including the complete integration of ART and PMTCT programs, systematic reduction of barriers to facilitate doubling the number of ART sites in less than a year, building consensus with stakeholders, and securing additional resources for the new program. During the planning and implementation process, several lessons were learned which are considerations for countries transitioning to "treat-all": Comprehensive change requires effective government leadership and coordination; national clinical guidelines must accommodate health system limitations; ART services and commodities should be decentralized within facilities; the general public should be well informed about major changes in the national HIV program; and patients should be educated on clinic processes to improve program monitoring.
