Gastric antral vascular ectasia and its clinical correlates in patients with early diffuse systemic sclerosis in the SCOT trial.

ABSTRACT: To describe the prevalence and clinical correlates of endoscopic gastric antral vascular ectasia (GAVE; "watermelon stomach") in early diffuse systemic sclerosis (SSc).Subjects with early, diffuse SSc and evidence of specific internal organ involvement were considered for the Scleroderma: Cyclophosphamide Or Transplant (SCOT) trial. In the screening procedures, all patients underwent upper gastrointestinal endoscopy. Patients were then categorized into those with or without endoscopic evidence of GAVE. Demographic data, clinical disease characteristics, and autoantibody data were compared using Pearson chi-square or Student t tests.Twenty-three of 103 (22.3%) individuals were found to have GAVE on endoscopy. Although not statistically significant, anti-topoisomerase I (anti-Scl70) was detected less frequently among those with GAVE (18.8% vs 44.7%; p = 0.071). Similarly, anti-RNP antibodies (anti-U1 RNP) showed a trend to a negative association with GAVE (0 vs 18.4%; p = 0.066). There was no association between anti-RNA polymerase III and GAVE. Patients with GAVE had significantly more erythema or vascular ectasias in other parts of the stomach (26.1% vs 5.0%; p = 0.003).Endoscopic GAVE was present on screening in almost one-fourth of these highly selected patients with early and severe diffuse SSc. While anti-Scl70 and anti-U1 RNP trended toward a negative association with GAVE, there was no correlation between anti-RNA Pol III and GAVE. Patients with GAVE had a higher frequency of other gastric vascular ectasias outside the antrum, suggesting that GAVE may represent part of the spectrum of the vasculopathy in SSc.

Project description:BackgroundGastric antral vascular ectasia is an infrequent cause of gastrointestinal-related blood loss manifesting as iron-deficiency anemia or overt gastrointestinal bleeding, and is associated with increased healthcare burdens. Endoscopic therapy of gastric antral vascular ectasia most commonly involves endoscopic thermal therapy. Endoscopic band ligation has been studied as an alternative therapy with promising results in gastric antral vascular ectasia.AimsThe primary aim was to compare the efficacy of endoscopic band ligation and endoscopic thermal therapy by argon plasma coagulation for the management of bleeding gastric antral vascular ectasia in terms of the mean post-procedural transfusion requirements and the mean hemoglobin level change. Secondary outcomes included a comparison of the number of sessions needed for cessation of bleeding, the change in transfusion requirements, and the adverse events rate.MethodsPubMed, Medline, SCOPUS, Google Scholar, and the Cochrane Controlled Trials Register were reviewed. Randomized controlled clinical trials and retrospective studies comparing endoscopic band ligation and endoscopic thermal therapy in bleeding gastric antral vascular ectasia, with a follow-up period of at least 6 months, were included. Statistical analysis was done using Review Manager.ResultsOur search yielded 516 papers. After removing duplicates and studies not fitting the criteria of selection, five studies including 207 patients were selected for analysis. Over a follow-up period of at least 6 months, patients treated with endoscopic band ligation had significantly lower post-procedural transfusion requirements (MD -2.10; 95% confidence interval (-2.42 to -1.77)) and a significantly higher change in the mean hemoglobin with endoscopic band ligation versus endoscopic thermal therapy (MD 0.92; 95% confidence interval [0.39-1.45]). Endoscopic band ligation led to a fewer number of required sessions (MD -1.15; 95% confidence interval [-2.30 to -0.01]) and a more pronounced change in transfusion requirements (MD -3.26; 95% confidence interval [-4.84 to -1.68]). There was no difference in adverse events.ConclusionResults should be interpreted cautiously due to the limited literature concerning the management of gastric antral vascular ectasia. Compared to endoscopic thermal therapy, endoscopic band ligation for the management of bleeding gastric antral vascular ectasia led to significantly lower transfusion requirements, showed a trend toward more remarkable post-procedural hemoglobin elevation, and a fewer number of procedures. Endoscopic band ligation may improve outcomes and lead to decreased healthcare burden and costs.

Project description:BackgroundEndoscopic band ligation (EBL) and radiofrequency ablation (RFA) have emerged as alternative therapies of gastric antral vascular ectasia (GAVE) in addition to endoscopic thermal therapy (ETT), but the optimum choice remains inconclusive.AimWe conducted a meta-analysis in order to compare these three treatments for GAVE.MethodsWe searched the electronic databases of PubMed, Embase and Cochrane Central Register of Controlled Trials without any language restrictions and also performed a manual literature search of bibliographies located in both retrieved articles and published reviews for eligible publications prior to December 8, 2021. We included comparative trials which had evaluated the efficacy and safety of interventions in adults (aged ≥ 18 years) diagnosed with symptomatic GAVE and was confirmed according to clinical backgrounds and upper gastrointestinal endoscopy. We included reports that compared three interventions, ETT, EBL, and RFA. The study was comprised of adults diagnosed with GAVE and focused on overall mortality, bleeding cessation, endoscopic improvement, complications, hospitalization, hemoglobin improvement, number of sessions and transfusion requirements.ResultsTwelve studies were performed involving a total of 571 participants for analysis. When compared with ETT, EBL achieved better bleeding cessation (OR 4.48, 95% CI 1.36-14.77, p = 0.01), higher hemoglobin improvement (MD 0.57, 95% CI 0.31-0.83, p < 0.01) and lower number of sessions (MD - 1.44, 95% CI - 2.54 to - 0.34, p = 0.01). Additionally, EBL was superior to ETT in endoscopic improvement (OR 6.00, 95% CI 2.26-15.97, p < 0.01), hospitalization (MD - 1.32, 95% CI - 1.91 to - 0.74, p < 0.01) and transfusion requirement (MD - 2.66, 95% CI - 4.67 to - 0.65, p = 0.01) with statistical significance, with the exception of mortality (OR 0.58, 95% CI 0.19-1.77, p = 0.34) and complication rate (OR 5.33, 95% CI 0.58-48.84, p = 0.14).ConclusionFor GAVE, we suggest that EBL be initially recommended, and APC and RFA be used as alternative treatment choices based upon a very low quality of evidence.
