Thalidomide as a treatment of intestinal angiodisplastic lesions in a patient with CREST syndrome – case report and literature review

Abstract

The severe ferropenic anemia secondary to digestive bleeding due to intestinalangiodisplastic lesions represents a great challenge. Commonly, angiodisplastic lesions aremultiples and disperse through the intestine and that fact limits local treatments. Over the lastyears, there was a great advance in the antiangiogenic treatment of intestinal angiodisplasticlesions and thalidomide was the most employed drug for this purpose. We report a case of a49 year-old patient with intestinal angiodisplastic lesions due to CREST syndrome (Calcinosis,Raynaud phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia). The patientpresented repeated episodes of digestive bleeding and did not achieve clinical improvementafter enteroscopy and argon plasma coagulation. The treatment consisting of the introductionof thalidomide 100mg per day demonstrated success. The case presented in this text revealssuccess in the use of thalidomide in the treatment of intestinal angiodisplastic lesions, probablyrepresenting a new therapeutic option
