Pharmacologically-induced activation of replication competent proviruses from latency in the presence of antiretroviral treatment (ART) has been proposed as a step towards curing HIV-1 infection. However, until now, approaches to reverse HIV-1 latency in humans have yielded mixed results. Here, we report a proof-of-concept phase Ib/IIa trial where 6 aviremic HIV-1 infected adults received intravenous 5 mg/m2 romidepsin (Celgene) once weekly for 3 weeks while maintaining ART. Lymphocyte histone H3 acetylation, a cellular measure of the pharmacodynamic response to romidepsin, increased rapidly (maximum fold range: 3.7–7.7 relative to baseline) within the first hours following each romidepsin administration. Concurrently, HIV-1 transcription quantified as copies of cell-associated un-spliced HIV-1 RNA increased significantly from baseline during treatment (range of fold-increase: 2.4–5.0; p = 0.03). Plasma HIV-1 RNA increased from <20 copies/mL at baseline to readily quantifiable levels at multiple post-infusion time-points in 5 of 6 patients (range 46–103 copies/mL following the second infusion, p = 0.04). Importantly, romidepsin did not decrease the number of HIV-specific T cells or inhibit T cell cytokine production. Adverse events (all grade 1–2) were consistent with the known side effects of romidepsin. In conclusion, romidepsin safely induced HIV-1 transcription resulting in plasma HIV-1 RNA that was readily detected with standard commercial assays demonstrating that significant reversal of HIV-1 latency in vivo is possible without blunting T cell-mediated immune responses. These finding have major implications for future trials aiming to eradicate the HIV-1 reservoir.Trial Registrationclinicaltrials.gov NTC02092116
To examine the morbidity of compensated cirrhosis type B, a cohort of 349 Western European, white patients (86% men; mean age, 44 years) with biopsy-proven cirrhosis was followed up for a mean period of 73 months and was studied for occurrence of hepatocellular carcinoma (HCC) and decompensation. At entry into the study all patients were tested for hepatitis B e antigen (HBeAg; 34% of patients were HBeAg-positive) and antibody to hepatitis delta virus (anti-HDV; 20% of patients were anti-HDV-positive); 48% of 252 patients tested were hepatitis B virus (HBV)-DNA-positive. During follow-up HCC developed in 32 (9%) of the 349 patients and decompensation was observed in 88 (28%) of 317 tumor-free patients. Five years after diagnosis, the probability of HCC appearance was 6% and the probability of decompensation was 23%. After the first episode of decompensation the probability of survival was 35% at 5 years. Cox's regression analysis identified three variables that independently correlated with HCC: age, serum levels of platelets, and liver firmness on physical examination. HBV (HBeAg or HBV-DNA) and HDV (anti-HDV) markers at presentation had no prognostic value for the development of HCC. In conclusion, a high proportion of patients with HBsAg-positive compensated cirrhosis do not experience worsening of their condition for several years, but once decompensation occurs life expectancy is poor. European, white patients with compensated cirrhosis type B are at consistent risk for HCC. Prognostic factors for HCC reflect an advanced stage of cirrhosis and support the hypothesis that development of a tumor could be the likely consequence of long-standing hepatic disease.
Groin injuries cause major problems in sports and particularly in football. Exercise is effective in treating adductor-related groin pain, but no trials have been published regarding the specific prevention of groin pain or prevention specifically targeting overuse injuries in sport using exercise programs. We performed a cluster-randomized trial including 55 football clubs representing 1211 players. The clubs were randomized to an exercise program aimed at preventing groin injuries (n=27) or to a control group training as usual (n=28). The intervention program consisted of six exercises including strengthening (concentric and eccentric), coordination, and core stability exercises for the muscles related to the pelvis. Physiotherapists assigned to each club registered all groin injuries. Twenty-two clubs in each group completed the study, represented by 977 players. There was no significant effect of the intervention (HR=0.69, 95% CI 0.40-1.19). The risk of a groin injury was reduced by 31%, but this reduction was not significant. A univariate analysis showed that having had a previous groin injury almost doubles the risk of developing a new groin injury and playing at a higher level almost triples the risk of developing a groin injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
