ABSTRACT
Ustekinumab and vedolizumab are key treatment options for Crohn's disease patients who fail anti-tumor necrosis factor (TNF) therapy. This updated meta-analysis aims to compare the efficacy and safety of these two drugs. We performed a systematic review in PubMed, Embase, and Cochrane databases searching for randomized and nonrandomized studies comparing vedolizumab versus ustekinumab in patients with Crohn's disease with previous anti-TNF failure or intolerance. The primary outcome was steroid-free clinical remission (SFR) at the pos-induction (12-16 weeks) and maintenance period (48-52 weeks). The odds ratio (OR) was used for binary outcomes with their respective 95% confidence interval (CI). Heterogeneity was assessed using the Cochran Q test and I2 statistics. This meta-analysis included 11 studies and 2724 patients. There was a significant difference favoring ustekinumab in SFR at pos-induction (OR, 1.44; 95% CI, 1.11-1.88; P = 0.006; I2 = 27%) and maintenance periods (OR, 1.86; 95% CI, 1.23-2.82; P = 0.003; I2 = 80%), in clinical remission at pos-induction period (OR, 2.04; 95% CI, 1.58-2.63; P < 0.001; I2 = 3%), and in treatment discontinuation due to adverse events (OR, 0.31; 95% CI, 0.16-0.60; P < 0.001; I2 = 0%). In patients with Crohn's disease with prior anti-TNF failure, ustekinumab showed higher SFR during both the pos-induction and maintenance period and a lower rate of treatment discontinuation due to adverse events.
ABSTRACT
BACKGROUND & AIMS: Endoscopic sphincterotomy (ES) is not mandatory before biliary stenting. The impact of ES before biliary stent placement remains uncertain. Previous studies have reported that ES can increase adverse event rates by up to 4.5 times compared to no ES. We aimed to assess the occurrence of post-ERCP adverse events following biliary stent placement with and without ES. METHODS: PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials. The primary outcome was post-ERCP pancreatitis (PEP). Subgroup analyses were performed with patients undergoing biliary drainage due to obstruction, using metal stents, and using plastic stents. Secondary outcomes included were post-procedure bleeding, perforation, stent/catheter occlusion, stent/catheter migration, and cholangitis. Heterogeneity was examined using I2 statistics, and a random-effects model was employed. Review manager 5.4 was used for statistical analyses. RESULTS: Seven RCTs with 1,022 patients were included. There was no significant difference between ES and non-ES groups (OR 0.46; 95% 0.19 to 1.09; p = 0.08; I2 = 59%) regarding PEP; however, a significant difference in bleeding rates was found between groups, favoring non-ES (OR 7.55; 95% CI 2.46 to 23.21; p = 0.0004; I2 = 0%). The analysis of the occurrence of cholangitis (OR 1.25; 95% CI 0.58 to 2.69; p = 0.56; I2 = 67%); perforation (OR 1.95; 95% CI 0.07 to 55.73; p = 0.70; I2 = 58%); stent/catheter migration (OR 1.95; 95% CI 0.07 to 55.73; p = 0.23; I2 = 6%); and stent/catheter occlusion (OR 0.90; 95% CI 0.37 to 2.19; p = 0.81; I2 = 0%) did not favor either group. CONCLUSION: Performing ES before biliary drainage does not impact the PEP rate but is associated with an increased postprocedure bleeding rate.
ABSTRACT
A hemofilia adquirida idiopática é uma condição médica extremamente rara, causada pelo desenvolvimento espontâneo de autoanticorpos contra o fator VIII (FVIII), com incidência estimada em 1,5/milhão de habitantes/ano. Embora esteja descrita a associação com outras doenças, seu fator precipitante é desconhecido. O quadro clínico se caracteriza por hemorragias graves, sem história pessoal ou familiar prévia de coagulopatias. Os autores relatam um caso clínico de hemofilia adquirida idiopática com evolução desfavorável.
Idiopathic acquired hemophilia is an extremely rare medical condition caused by the spontaneous development of autoantibodies against factor VIII (FVIII), with an estimated incidence of 1.5 / million inhabitants / year. Although the association with other diseases is described, its precipitating factor is unknown. The clinical picture is characterized by severe hemorrhages, with no previous personal or family history of coagulopathies. The authors report a clinical case of idiopathic acquired hemophilia with unfavorable outcome.
