Core Tip
Core Tip: This study indicates that sirolimus, a mammalian target of rapamycin inhibitor, effectively reduces bleeding episodes and improves hemoglobin levels in patients with gastrointestinal angiodysplasias (GIAD). By decreasing transfusions requirements and reducing vascular lesions, sirolimus shows promise as a novel therapeutic strategy. The treatment was generally well-tolerated, with mild and manageable side effects. While these findings are encouraging, future larger, controlled trials are needed to validate sirolimus’s role in managing GIAD.
