dc.description.abstractEnObjective:We aimed to determine the contribution of inflammasome activation in chronic low-grade systemic inflammation observed in patients with HIV (PWH) on long-term suppressive antiretroviral therapy (ART) and to explore mechanisms of such activation.Design:Forty-two PWH on long-term suppressive ART (HIV-RNA < 40copies/ml) were compared with 10 HIV-negative healthy controls (HC).Methods:Inflammasome activation was measured by dosing mature interleukin (IL)-1β and IL-18 cytokines in patient serum. We explored inflammasome pathways through ex vivo stimulation of PWH primary monocytes with inflammasome activators; expression of inflammasome components by transcriptomic analysis; and metabolomics analysis of patient sera.Results:Median (Q1; Q3) age, ART and viral suppression duration in PWH were 54 (48; 60), 15 (9; 20) and 7.5 (5; 12) years, respectively. Higher serum IL-18 was measured in PWH than in HC (61 (42; 77) vs. 36 (27-48pg/ml), P = 0.009); IL-1β was detected in 10/42 PWH (0.5 (0.34; 0.80) pg/ml) but not in HC. Monocytes from PWH did not produce more inflammatory cytokines in vitro, but secretion of IL-1β in response to NOD like receptor family, pyrin domain containing 3 (NLRP3) inflammasome stimulation was higher than in HC. This was not explained at the transcriptional level. We found an oxidative stress molecular profile in PWH sera.Conclusion:HIV infection with long-term effective ART is associated with a serum inflammatory signature, including markers of inflammasome activation, and an increased activation of monocytes upon inflammasome stimulation. Other cells should be investigated as sources of inflammatory cytokines in PWH. Oxidative stress might contribute to this chronic low-grade inflammation.
