Adolescents and young adults with HIV and unsuppressed viral load: where do we go from here?

Abstract

Purpose of review Adolescents and youth living with HIV (AYLHIV) have worse outcomes at all stages of the care cascade when compared with adults, yet adolescents and youth with unsuppressed viral load are typically excluded from phase 3 studies of novel HIV therapeutic agents and emerging strategies. Long-acting agents have the potential to radically change outcomes for young people struggling with adherence to daily oral HIV medications. Recent findings 1.5 million children aged less than 15 years live with HIV and more than 100 000 acquire HIV perinatally every year. Adolescents and youth aged 10–24 years comprise ∼40% of global incident HIV infections. Rates of viral suppression among AYLHIV vary markedly from 44 to 88%, resulting in morbidity and risks of transmission to partners and infants. Virological failure is mostly due to poor adherence, and AYLHIV express high levels of interest and acceptability of alternatives to oral daily medications, such as long-acting antiretroviral formulations. Emerging data regarding their use in populations with unsuppressed viral load are encouraging. Summary AYLHIV, including populations without virologic suppression, must be prioritized for the programmatic implementation and research of long-acting HIV drugs and other therapeutic strategies to prevent morbidity and mortality and to ultimately end the HIV epidemic.
