Severe thrombocytopenia associated to bevacizumab in a patient with scleroderma, gastrointestinal angiodysplasias and refractory gastrointestinal bleeding

Le résumé fourni par la source

This case report discusses the medical history of a 64-year-old woman diagnosed with scleroderma and diffuse gastrointestinal angiodysplasia. The patient received bevacizumab (BVZ) therapy to address gastrointestinal bleeding that was unresponsive to endoscopic treatment. Subsequently, she developed severe thrombocytopenia. Although there were suspicions of an immune-mediated mechanism resulting from BVZ treatment, the laboratory results did not provide conclusive evidence. The patient underwent transfusions, received gamma globulin, and was treated with Romiplostim. Over time, her platelet levels gradually improved, and the bleeding was successfully controlled. It's worth noting that BVZ-induced thrombocytopenia is a relatively rare yet severe adverse effect. Recognizing and understanding the mechanisms behind thrombocytopenia is essential for developing safer treatment approaches. Further research is required to identify potential risk factors associated with this condition.
