Clinical features and treatment of hematopoietic stem cell transplantation-associated gastric antral vascular ectasia.

Abstract

Gastric antral vascular ectasia (GAVE) may occur after hematopoietic stem cell transplantation (HSCT) and cause severe and prolonged gastric bleeding. The underlying pathology of transplant-associated GAVE (HSCT-GAVE) is poorly understood and an effective therapeutic strategy has not been established yet. We retrospectively reviewed the medical records of 230 consecutive allogeneic transplant recipients in our institution between January 1997 and June 2002. We identified five patients who developed HSCT-GAVE (2.2%). Four patients had bleeding from HSCT-GAVE and one patient had HSCT-GAVE discovered incidentally. The clinical features of these patients were similar in that they all received conditioning treatment with busulfan and had history of thrombotic microangiopathy. Furthermore, treatment with a beta-blocker apparently improved the outcome of HSCT-GAVE in three patients.
