Outcomes of Integrase Inhibitor-based Antiretroviral Therapy in a Clinical Cohort of Treatment-experienced Children, Adolescents and Young Adults With HIV Infection.


ABSTRACT:

Background

Data on integrase strand transfer inhibitor (INSTI) use in children, adolescents and young adults with HIV are limited. We evaluated virologic and safety outcomes following INSTI initiation among treatment-experienced children, adolescents and young adults.

Methods

The DC Cohort is a multicenter observational study of individuals receiving HIV care in Washington, DC. This analysis included treatment-experienced participants 0-24 years of age who initiated an INSTI during 2011-2017. Viral suppression (VS) and safety outcomes were quantified. Differences in VS by age, sex and CD4 count were assessed using Kaplan-Meier curves.

Results

Of 141 participants (median age 20 years; 35% <18 years; 60% male; 89% Black; 62% perinatally-infected), 35% had VS and 65% lacked VS on INSTI initiation. Dolutegravir was the most commonly prescribed INSTI (55%). Among participants without VS at INSTI initiation, 46% achieved VS after a median of 2.7 months. Participants 13-24 (vs. 0-12) years old (P = 0.011) and participants with CD4 counts <350 (vs. >500) cells/μL were less likely to achieve VS (P < 0.001). Among participants with VS at INSTI initiation, 51% sustained VS through a median of 11.0 months of follow-up; of the 49% with transient viremia, 77% later achieved VS again. There were no safety concerns associated with the use of INSTIs.

Conclusions

More than half of treatment-experienced children, adolescents and young adults with detectable viremia at INSTI initiation did not achieve VS, while half of those with prior VS experienced transient viremia. Further evaluation of long-term outcomes associated with INSTI use among children, adolescents and young adults is warranted.
