Objective: To compare the incidence of dyslipidemia in people with HIV receiving integrase inhibitors (INSTI) versus boosted protease inhibitors (PI/b) and nonnucleoside reverse transcriptase inhibitors (NNRTI) within RESPOND consortium of prospective cohorts. Methods: Participants were eligible if they were at least 18 years, without dyslipidemia and initiated or switched to a three-drug antiretroviral therapy (ART)-regimen consisting of either INSTI, NNRTI, or PI/b for the first time, between 1 January 2012 and 31 December 2018. Dyslipidemia was defined as random total cholesterol more than 240 mg/dl, HDL less than 35 mg/dl, triglyceride more than 200 mg/dl, or initiation of lipid-lowering therapy. Poisson regression was used to determine the adjusted incidence rate ratios. Follow-up was censored after 3 years or upon ART-regimen discontinuation or last lipid measurement or 31 December 2019, whichever occurred first. Results: Overall, 4577 people with HIV were eligible (INSTI = 66.9%, PI/b = 12.5%, and NNRTI = 20.6%), 1938 (42.3%) of whom were ART-naive. During 1.7 (interquartile range, 0.6–3.0) median years of follow-up, 1460 participants developed dyslipidemia [incidence rate: 191.6 per 1000 person-years, 95% confidence interval (CI) 182.0–201.7]. Participants taking INSTI had a lower incidence of dyslipidemia compared with those on PI/b (adjusted incidence rate ratio 0.71; CI 0.59–0.85), but higher rate compared with those on NNRTI (1.35; CI 1.15–1.58). Compared with dolutegravir, the incidence of dyslipidemia was higher with elvitegravir/cobicistat (1.20; CI 1.00–1.43) and raltegravir (1.24; CI 1.02–1.51), but lower with rilpivirine (0.77; CI 0.63–0.94). Conclusion: In this large consortium of heterogeneous cohorts, dyslipidemia was less common with INSTI than with PI/b. Compared with dolutegravir, dyslipidemia was more common with elvitegravir/cobicistat and raltegravir, but less common with rilpivirine.

Clinical impact of occult hepatitis B virus infection in immunosuppressed patients

The development of sensitive assays to detect small amounts of hepatitis B virus (HBV) DNA has favored the identification of occult hepatitis B infection (OBI), a virological condition characterized by a low level of HBV replication with detectable levels of HBV DNA in liver tissue but an absence of detectable surface antigen of HBV (HBsAg) in serum. The gold standard to diagnose OBI is the detection of HBV DNA in the hepatocytes by highly sensitive and specific techniques, a diagnostic procedure requiring liver tissue to be tested and the use of non-standardized non-commercially available techniques. Consequently, in everyday clinical practice, the detection of anti-hepatitis B core antibody (anti-HBc) in serum of HBsAg-negative subjects is used as a surrogate marker to identify patients with OBI. In patients with chronic hepatitis C (CHC), OBI has been identified in nearly one-third of these cases. Considerable data suggest that OBI favors the increase of liver damage and the development of hepatocellular carcinoma (HCC) in patients with CHC. The data from other studies, however, indicate no influence of OBI on the natural history of CHC, particularly regarding the risk of developing HCC.
