Given the known side effects of antiretroviral therapy (ART), treatment interruption has been hypothesized to improve quality of life. However, this theory was recently disproven in a substudy of the SMART trial, which compared outcomes of continuous ART with outcomes of CD4-guided episodic ART.
A total of 1225 SMART participants in the U.S. completed standardized quality-of-life assessments at baseline, at months 4, 8, and 12, and then annually thereafter. At baseline, 76% of participants were receiving ART, 50% reported very good or excellent health, and the median CD4 count was 575 cells/mm3.
During a mean follow-up of 2.4 years, whenever a difference arose in quality-of-life measures, the results favored the continuous-therapy group over …
