Inflammasome activation is increased in people with HIV (PWH), but its relationship with coronary plaque is poorly understood in this setting. In a large HIV cardiovascular prevention cohort, relationships between caspase-1, IL-1β, and IL-18 and coronary plaque indices were assessed by multivariate logistic regression. Higher IL-18 and IL-1β were associated with Leaman score, an integrative measure of plaque burden and composition. As Leaman score >5 is associated with cardiovascular events in the general population, future work is needed to determine how the inflammasome relates to events and whether strategies to reduce its activation affect events or plaque progression among PWH.
