A randomized, placebo-controlled trial of oral beclomethasone dipropionate as a prednisone-sparing therapy for gastrointestinal graft-versus-host disease.

We tested the hypothesis that oral beclomethasone dipropionate (BDP) would control gastrointestinal graft-versus-host disease (GVHD) in patients with anorexia, vomiting, and diarrhea. Patients were randomized to prednisone for 10 days and either oral BDP 8 mg/d (n = 62) or placebo (n = 67) tablets for 50 days. At study day 10, prednisone was rapidly tapered while continuing study drug.

Evaluation of thymic output by measurement of T-cell-receptor gene rearrangement excisional circles (TREC) in patients who have received fludarabine.

The role of the thymus in immune reconstitution in adults receiving chemotherapy is controversial. Detection of T-cell-receptor gene rearrangement excisional circles (TREC) in peripheral blood T cells has been shown to estimate thymic output. Therefore, we measured TREC levels to assess the contribution of the thymus to immune recovery following treatment with fludarabine.
