RESUMEN
Objective: Argatroban is a highly promising drug for the treatment of acute ischemic stroke (AIS), but there is currently insufficient strong evidence regarding the efficacy and safety of using Argatroban in the treatment of AIS. Therefore, we conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of Argatroban in the treatment of AIS. Methods: Articles on PubMed, Embase and the Cochrane Library databases were searched from these websites' inceptions to 2th February 2023. Randomized controlled trials and observational studies on Argatroban therapy for acute ischemic stroke were included. Meta-analyses were conducted using a random-effects model. Results: Fourteen studies involving 10,315 patients were included in the meta-analysis. The results showed a significant reduction in the rate of early neurological deterioration (END) in the Argatroban group compared with the control group (OR = 0.47, 95% CI: 0.31-0.73, I2 = 15.17%). The rates of adverse events were no significant difference between the two groups (ICH: OR = 1.02, 95% CI: 0.68-1.51, I2 = 0.00%; major extracranial bleeding: OR = 1.22, 95% CI: 1.01-1.48, I2 = 0.00%; mortality: OR = 1.16, 95% CI: 0.84-1.59, I2 = 0.00%). However, the rates of mRS score of 0-1 (OR = 1.38, 95% CI: 0.71-2.67, I2 = 77.56%) and mRS score of 0-2 (OR = 1.18, 95% CI: 0.98-1.42, I2 = 0.00%) during the 90 days did not significantly improved in the Argatroban group. Subgroup analyses showed that the rate of END (OR = 0.41, 95% CI: 0.26-0.65, I2 = 2.77%) and mRS score of 0-2 (OR = 1.38, 95% CI: 1.06-1.81, I2 = 0.00%) had significantly improved when the intervention group adopted Argatroban plus Antiplatelet. Conclusion: Argatroban can improve neurological deterioration, with a low incidence of adverse events such as bleeding and death, and general analysis showed no improvement in mRS. However, subgroup analysis suggests that compared to mono-antiplatelet therapy, combination therapy of Argatroban combined with antiplatelet therapy significantly reduced the incidence of END and improved mRS scores. After using Argatroban, there was no increase in the risk and mortality of intracranial hemorrhage and other bleeding sites.
RESUMEN
BACKGROUND: Malignant obstructive jaundice (MOJ) is a common pathologic manifestation of malignant biliary obstruction. Recently, several clinical trials have explored the clinical effectiveness of intraluminal 125I seed-based brachytherapy for MOJ patients, and various outcomes have been reported. AIM: To assess the efficacy and safety of percutaneous biliary stents with 125I seeds compared to conventional metal stents in patients with unresectable MOJ. METHODS: A systematic search of English-language databases (PubMed, Embase, Cochrane Library, and Web of Science) was performed to identify studies published prior to June 2020 that compared stents with or without 125I seeds in the treatment of unresectable MOJ. The outcomes analyzed included primary outcomes (stent patency and overall survival) and secondary outcomes (complications and liver function parameters). RESULTS: Six randomized controlled trials and four retrospective studies involving 875 patients were eligible for the analysis. Of the 875 included patients, 404 were treated with 125I seed stents, while 471 were treated with conventional stents. Unadjusted pooled analysis demonstrated that compared to conventional stents, 125I seed stents extended the stent patency time [hazard ratio (HR) = 0.36, 95% confidence interval (CI) = 0.28-0.45, P < 0.0001] and overall survival period (HR = 0.52, 95%CI = 0.42-0.64, P < 0.00001). Subgroup analyses based on the type of 125I seed stent and type of study design showed consistent results. However, there were no significant differences in the occurrence of total complications [odds ratio (OR) = 1.12, 95%CI = 0.75-1.67, P = 0.57], hemobilia (OR = 1.02, 95%CI = 0.45-2.3, P = 0.96), pancreatitis (OR = 1.79, 95%CI = 0.42-7.53, P = 0.43), cholangitis (OR = 1.13, 95%CI = 0.60-2.13, P = 0.71), or pain (OR = 0.67, 95%CI = 0.22-2, P = 0.47). In addition, there were no reductions in the levels of serum indices, including total bilirubin [mean difference (MD) = 10.96, 95%CI = -3.56-25.49, P = 0.14], direct bilirubin (MD = 7.37, 95%CI = -9.76-24.5, P = 0.4), alanine aminotransferase (MD = 7.52, 95%CI = -0.71-15.74, P = 0.07), and aspartate aminotransferase (MD = -4.77, 95%CI = -19.98-10.44, P = 0.54), after treatment. Publication bias was detected regarding the outcome overall survival; however, the conclusions were not changed after the adjustment. CONCLUSION: Placement of stents combined with brachytherapy using 125I seeds contributes to a longer stent patency and higher overall survival than placement of conventional stents without extra complications or severe liver damage. Thus, it can be considered an effective and safe treatment for unresectable MOJ.
