RESUMEN

BACKGROUND: Increased levels of markers of systemic inflammation have been associated with serious non-AIDS events even in patients on fully suppressive antiretroviral therapy. We explored residual viremia and systemic inflammation markers in patients effectively treated with ritonavir-boosted protease inhibitor monotherapy (PImono). METHODS: HIV-infected adults with persistent HIV-RNA<50 copies/ml and treated with either a) PImono or b) standard triple-drug cART were recruited for this cross-sectional, exploratory study. Plasma samples were tested for high-sensitivity CRP (hsCRP), Serum Amyloid A (SAA), soluble CD14, IL-6, IL-8 and Cytochrome C. HIV-RNA was measured by real-time PCR (detection limit of 10 copies/ml). RESULTS: 81 patients were recruited (31% on PImono). Two out of 25 (8%) and 3 of 56 (5.4%) patients from the PImono and cART groups respectively had detectable HIV-RNA. Significant correlation between SAA and hsCRP was observed (0.804). No difference between groups was found on prevalence of hsCRP>3 mg/l (21% vs 20% in the PImono and cART groups respectively; p=0.577) or SAA>6.4 mg/l (38% vs 22% in the PImono and cART groups respectively; P=0.172). In a univariate analysis IL6 and IL8 levels were associated with SAA>6.4 mg/l (OR=1.74 and 1.46; 95% CI=1.00-3.03 and 1.06-2.01; p=0.051 and 0.02 respectively) and hsCRP>3 mg/l in (OR=2.00 and 1.37; 95% CI=1.09-3.69 and 1.02-1.85; p=0.026 and 0.039 respectively). CONCLUSIONS: We found no evidence of increased levels of inflammatory biomarkers or higher prevalence of residual viraemia in patients effectively suppressed on PImono as compared with patients on standard cART.
