Thalidomide Versus Argon Plasma Coagulation in Gastric Antral Vascular Ectasia(GAVE)-Related Anaemia in Cirrhosis (TAG Trial)
Sponsor: Institute of Liver and Biliary Sciences, India
Summary
Gastric Antral Vascular Ectasia (GAVE) is an erosive form of gastritis distinguished by veno-capillary ectasia, which manifests as tortuous columns of dilated vessels. Histologically, these vessels show dilated mucosal capillaries filled with fibrin thrombi, accompanied by fibromuscular hyperplasia and spindle cell proliferation of the lamina propria. GAVE is prevalent in about 12% of patients with cirrhosis, with 60-70% of these patients becoming transfusion-dependent due to severe anaemia caused by GAVE related bleeding. The most commonly used treatment for GAVE is endoscopic therapy using Argon Plasma Coagulation (APC), which, while effective, often requires multiple sessions due to a high recurrence rate of 30-60%. These frequent interventions increase the burden on patients and healthcare systems. As a result, alternative treatments have been sought. Thalidomide, known for its potent antiangiogenic properties, significantly lowers vascular endothelial growth factor (VEGF) levels, offering a promising non-invasive treatment option. Early studies, such as those by García-Pagán have demonstrated thalidomide's effectiveness in reducing transfusion requirements and managing bleeding in cirrhotic patients with GAVE, yet its comprehensive efficacy and safety profile remains under-studied. This project aims to rigorously evaluate the efficacy and safety of thalidomide compared to APC in managing GAVE-related anemia in cirrhotic patients. Through a controlled trial, this study will provide vital data to potentially shift treatment paradigms, enhance patient quality of life, and reduce the need for repetitive invasive procedures.
