Oral beclomethasone dipropionate for the treatment of gastrointestinal acute graft-versus-host disease (GVHD)

Acute graft-versus-host disease (aGVHD) remains one of the most severe complications after allogeneic transplantation; in particular, the presence of gut involvement has been related to increased mortality and poorer response. The use of systemic steroids remains the standard for first-line treatment despite its severe secondary effects. Beclomethasone dipropionate (BDP) is a topically active corticosteroid with low absorption, thereby avoiding many of the deleterious side effects associated with systemic steroids. In the present study we analyzed the efficacy of BDP in a series of 26 patients who were diagnosed with grade 1 and 2 gastrointestinal aGVHD. Twenty patients (77%) responded to BDP treatment, 17 (65.5%) reached complete remission (CR), and 3 (11.5%) showed partial response. Among those patients who reached CR, 5 relapsed, although 1 of them reached second CR after a second course of BDP; therefore, 13 (50%) of the 26 patients did not require systemic steroids to treat gastrointestinal aGVHD. CR rates in those showing gastrointestinal symptoms were 68% for patients with persistent nausea, 50% for those with vomiting, and 54% for those with diarrhea (P = .2). No patient included in the study developed any symptom related to adrenal axis suppression. Thirteen patients (50%) developed >= 1 infectious episode during the first 100 days after transplantation. Transplant-related mortality was 0% at 100 days, and overall transplant-related mortality was 30%, with only 2 patients dying due to infectious complications. Therefore, our study shows that monotherapy with oral BDP is an effective initial therapeutic approach for mild to moderate intestinal GVHD, which avoids complications related to systemic steroids.
