Background: This study aimed to assess the efficacy, optimal dosing, and timing of colchicine therapy in reducing major adverse cardiovascular events (MACE), its impact on inflammatory markers, and safety concerns in patients following acute coronary syndrome (ACS) through a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: A comprehensive search of PubMed, Embase, and the Cochrane Library was conducted in accordance with PRISMA guidelines to identify RCTs comparing colchicine versus placebo or standard treatment in ACS patients. The primary outcome was MACE and secondary outcomes included all-cause and cardiovascular mortality, non-fatal MI, stroke, revascularization, heart failure, CRP/hs-CRP changes, and adverse effects. Fifteen RCTs involving 19,131 patients were analyzed. Results: The benefit of colchicine in reducing MACE risk was marginally significant (RR = 0.79, 95% CI: 0.63–0.99, p = 0.04, I² = 59%). No significant reduction was observed for all-cause mortality, cardiovascular mortality, other cardiovascular outcomes, early initiation of colchicine (≤3 days), or choice of dosage (≤0.5 mg/day vs. >0.5 mg/day). The findings pertaining to the delayed time-to-initiation (>3 days) and changes in CRP or hs-CRP levels were inconclusive. Gastrointestinal side effects, especially diarrhea (RR = 1.76, 95% CI: 1.16–2.66, p = 0.001), were most common. No increase in hematologic events or infections was observed. Conclusions: Colchicine potentially reduces MACE in ACS patients, without evidence of benefit in improving all-cause mortality or other cardiovascular outcomes. Gastrointestinal intolerance is the most common side effect. This result is consistent with current clinical guidelines: a Class IIb recommendation for colchicine use in ACS. There is a need for further high-quality trials to refine patient selection and optimize treatment regimens.

Background: Psoriasis patients who are seropositive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) face an elevated risk of hepatitis B virus reactivation (HBVr) when treated with cytokine inhibitors. This study aims to elucidate the risk in this population. Methods: A retrospective chart review was conducted to assess the risk of HBVr in 73 psoriasis patients treated with cytokine inhibitors from 2013 to 2023. Additionally, a systematic review and meta-analysis were performed, pooling data from 10 studies (including our cohort) and adhering to PRISMA guidelines. Statistical heterogeneity was assessed using the I² statistic, and pooled proportions were calculated using a random effects model. Results: No HBVr cases were observed among the 11 HBsAg+ patients in the cohort. However, two of the sixty-two (3.2%) HBsAg−/HBcAb+ patients experienced reactivation during therapy, with outcomes ranging from spontaneous recovery in one case to death from hepatic failure despite antiviral treatment in the other. The meta-analysis, pooling data from 10 studies, revealed a reactivation rate of 21.2% (95% CI: 9.4–41.0%) in HBsAg+ patients without prophylaxis and 4.4% (95% CI: 2.2–8.7%) in HBsAg−/HBcAb+ patients. Conclusion: Antiviral prophylaxis is essential for HBsAg+ patients receiving cytokine inhibitors, given the high risk of reactivation. Despite the lower risk for HBsAg−/HBcAb+ patients, the potential severity of outcomes demands careful monitoring and timely action.

Background and Aim: Transcatheter liver-directed intra-arterial therapies are mainstream treatment options for intermediate-stage hepatocellular carcinoma (HCC). However, the effect of low skeletal muscle mass (LSMM) on overall survival (OS) in these patients remains uncertain. We aimed to ascertain the prevalence and prognostic effect of LSMM in this population. Method: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive search was performed in the PubMed and Embase databases until Oct 2023. Random-effects meta-analysis was performed to determine the pooled prevalence of LSMM and calculate the hazard ratio (HR) for OS with a 95% confidence interval (CI) in patients with intermediate-stage HCC undergoing various transarterial therapies, comparing those with and without LSMM. Results: Twelve studies involving 2450 patients were included. The pooled prevalence of LSMM was 46% (95% CI, 38–55%), and the results were consistent across different treatments, regions, and age subgroups. The meta-analysis indicated that LSMM was significantly associated with decreased OS (HR, 1.78; 95% CI, 1.36–2.33; I², 75%). Subgroup analyses reassured the main findings across various therapies, including transarterial chemoembolization (TACE) (HR, 1.68; 95% CI, 1.23–2.30; I², 81%), transarterial embolization (TAE) (HR, 2.45; 95% CI, 1.42–4.22; I², 0%), and transarterial radioembolization (TARE) (HR, 1.94; 95% CI, 1.01–3.73; I², 0%). Conclusions: In intermediate-stage HCC, LSMM is common and associated with reduced OS. To achieve an optimal prognosis, clinicians should incorporate routine LSMM measurement into practice, while caring for patients with intermediate-stage HCC, irrespective of TACE, TAE, and TARE.
