AbstractFailure to control variceal bleeding with current recommendations occurs in 10 to 20% of cases. This systematic review and meta-analysis analyzes the experience, results, and complications of “bridge” therapies for failure to control acute variceal bleeding: balloon tamponade and esophageal stents. The main outcomes assessed were failure to control bleeding and mortality in the short-term and medium-term follow-up, and adverse events. Balloon tamponade studies had a pooled rate of short-term failure to control bleeding of 35.5%, and adverse events in over 20% of cases; 9.7% resulting in death. Stenting failed to control bleeding in the short term and medium term in 12.7 and 21.5% of cases of severe or refractory variceal bleeding, respectively, despite stent migration in 23.8% of cases. Medium-term mortality rates were similar in both therapies. Although only one trial compared these treatments, the available evidence consistently supports that stents serve as a better and safer bridge therapy in refractory acute variceal bleeding.

IntroductionHigh blood pressure (BP) in acute stroke has adverse outcomes. Transdermal glyceryl trinitrate (GTN) has beneficial properties in controlling BP. The 2016 meta-analysis and 2017 Cochrane review showed that transdermal GTN was beneficial in a small patient subgroup with stroke onset ≤6 hours. Larger studies focusing on this patient subgroup have since been conducted. We report the protocol for an updated systematic review and meta-analysis on the safety and benefits of transdermal GTN in acute stroke.Methods and analysisWe will search Medline, Pubmed, Embase, CINAHL and Cochrane Library from inception until June 2020 for randomised trials that report the efficacy and safety of transdermal GTN versus placebo/control therapy among adult patients with acute stroke. Primary outcomes include in-hospital mortality, BP lowering and late functional status. Secondary outcomes include early, late, resource utilisation and surrogate outcomes. Safety outcomes include reported adverse events. Reviewers will first screen titles and abstracts, and then full texts, to identify eligible studies. Independently and in duplicate, they will extract data, assess risk of bias (RoB) using a modified Cochrane RoB tool and quality of evidence using Grading of Recommendations, Assessment, Development and Evaluation. Disagreement will be resolved by discussion and consultation with an external reviewer if necessary. Using a random-effects model, we will report effect sizes using relative risks and 95% CIs. We will perform predefined subgroup analyses: intracerebral haemorrhage versus ischaemic stroke; minor (NIHSS (National Institutes of Health Stroke Scale) ≤five) versus major (NIHSS >five) ischaemic stroke; ischaemic stroke with versus without thrombolysis; prehospital versus non-prehospital settings; time from stroke to randomisation ≤6 versus >6 hours and high versus low overall RoB studies. We will also perform trial sequential analysis for the primary outcomes.Ethics and disseminationEthics board approval is unnecessary. PROSPERO registration has been obtained. The results will be disseminated through publication in a peer-reviewed journal.PROSPERO registration numberCRD42020173093.

Background Recent randomised trials showed benefit for anti-inflammatory therapies in coronary disease but excluded stroke. The prognostic value of blood inflammatory markers after stroke is uncertain and guidelines do not recommend their routine measurement for risk stratification. Methods We performed a systematic review and meta-analysis of studies investigating the association of C-reactive protein (CRP), interleukin-6 (IL-6) and fibrinogen and risk of recurrent stroke or major vascular events (MVEs). We searched EMBASE and Ovid Medline until 10/1/19. Random-effects meta-analysis was performed for studies reporting comparable effect measures. Results Of 2,515 reports identified, 39 met eligibility criteria (IL-6, n = 10; CRP, n = 33; fibrinogen, n = 16). An association with recurrent stroke was reported in 12/26 studies (CRP), 2/11 (fibrinogen) and 3/6 (IL-6). On random-effects meta-analysis of comparable studies, CRP was associated with an increased risk of recurrent stroke [pooled hazard ratio (HR) per 1 standard-deviation (SD) increase in loge-CRP (1.14, 95% CI 1.06–1.22, p < 0.01)] and MVEs (pooled HR 1.21, CI 1.10–1.34, p < 0.01). Fibrinogen was also associated with recurrent stroke (HR 1.26, CI 1.07–1.47, p < 0.01) and MVEs (HR 1.31, 95% CI 1.15–1.49, p < 0.01). Trends were identified for IL-6 for recurrent stroke (HR per 1-SD increase 1.17, CI 0.97–1.41, p = 0.10) and MVEs (HR 1.22, CI 0.96–1.55, p = 0.10). Conclusion Despite evidence suggesting an association between inflammatory markers and post-stroke vascular recurrence, substantial methodological heterogeneity was apparent between studies. Individual-patient pooled analysis and standardisation of methods are needed to determine the prognostic role of blood inflammatory markers and to improve patient selection for randomised trials of inflammatory therapies.
