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.

Detailed description

Aim: To evaluate and compare the efficacy and safety of thalidomide with argon plasma coagulation (APC) in managing gastric antral vascular ectasia (GAVE)-related anaemia in patients with cirrhosis. Hypothesis: Thalidomide, due to its antiangiogenic effects, will more effectively reduce GAVE-related bleeding, improve haemoglobin levels, and decrease transfusion dependency compared to APC in patients with cirrhosis and GAVE-related anaemia. Study Design: Single-centre, open-label, randomised controlled trial to compare the efficacy and safety of thalidomide versus argon plasma coagulation (APC) in managing GAVE-related anaemia in cirrhotic patients. Study Population: Adult patients (aged 18-65 years) diagnosed with cirrhosis and endoscopically confirmed GAVE-related anaemia, presenting at the Institute of Liver and Biliary Sciences. Randomization: Patients will be randomly assigned to receive either thalidomide or APC in a 1:1 ratio by block randomization method with block size of 10 and it will be implemented by using ILBS IWRS facility. Follow-up and Assessments: * Patients will be followed every two weeks for the first month, then monthly up to six months. Assessments will include haemoglobin levels, the number of transfused blood units, the frequency of bleeding episodes, hospitalizations, and the number of required endoscopic sessions. * Adverse effects will be monitored and recorded at each visit.
