The chemokine CXCL13 may play a major role in recruitment of B cells and T-cell subsets expressing the chemokine receptor CXCR5 to the CNS in multiple sclerosis (MS), and may be a useful biomarker for treatment effects in MS. Furthermore, CXCL13 or its receptor CXCR5 should be considered as therapeutic targets in MS.
This study evaluated the long-term efficacy and safety of nalmefene treatment in reducing alcohol consumption. We randomised (1:3) 675 alcohol-dependent patients ≥ 18 years of age to 52 weeks of as-needed treatment with placebo or nalmefene 18 mg/day: A total of 112 patients (68%) in the placebo group and 310 (62%) in the nalmefene group completed the study. At month 6, the co-primary outcome variables showed no statistically-significant differences between the treatment groups; but at month 13, nalmefene was more effective than placebo, both in the reduction of the number of heavy drinking days (HDDs) (- 1.6 days/month (95% CI - 2.9; - 0.3); p = 0.017) and the reduction of total alcohol consumption (TAC) (- 6.5 g/day last month (95% CI - 12.5; - 0.4); p = 0.036). In a subgroup analysis of patients with high/very high drinking risk levels at screening and at randomisation (the target population), there was a significant effect in favour of nalmefene on TAC at month 6, and on both HDD and TAC at month 13. Improvements in Clinical Global Impression and liver enzymes were greater with nalmefene, compared to placebo. Most adverse events were mild or moderate, and transient; adverse events, including those leading to dropout, were more common with nalmefene. This study provides evidence for the long-term safety and efficacy of nalmefene as-needed in alcohol-dependent patients whom continue to drink heavily, following a brief intervention.
A modified and time-saving CBT programme is effective in the treatment of hypochondriasis, although the two psychotherapeutic interventions differed in structure.
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.
