Human leukocyte antigen (HLA) DR15 is associated with reduced incidence of acute GVHD in HLA-matched allogeneic transplantation but does not impact chronic GVHD incidence.

The DR15 allele at the HLA DRB1 locus is a marker for immune-mediated bone marrow failure syndromes. We hypothesized that HLA DR15 plays a role in T-cell interactions with hematopoiesis and investigated the role of HLA DR15 on graft-versus-host disease (GVHD) and graft-versus-leukemia effects in HLA-matched allogeneic blood or marrow transplantation (BMT) performed for myeloid malignancies. We performed a retrospective analysis of 119 consecutive related and 48 consecutive unrelated allogeneic BMT for myeloid malignancies treated between 1991 and 2005 to investigate the influence of HLA DR15 on overall survival (OS), progression-free survival (PFS), and incidence of grades II to IV acute GVHD.

Long-term use of oral beclomethasone dipropionate for the treatment of gastrointestinal graft-versus-host disease.

Treatment of severe acute and chronic gastrointestinal (GI) graft-versus-host disease (GVHD) with prolonged high-dose systemic corticosteroids has limited success and considerable toxicity. Beclomethasone dipropionate (BDP) is a potent topically active steroid. We treated 15 patients with acute (n = 2) or chronic (n = 13) GI GVHD refractory to systemic corticosteroids with 28-day courses of oral BDP (2 mg 4 times daily).

Arterial thrombosis in four patients treated with thalidomide.

Thalidomide has been associated with venous thrombotic events, as reported in the post-marketing surveillance reports by Celgene Corporation; as well as case reports in the literature. Seven arterial thrombotic events have been reported in patients receiving thalidomide with 3 cases occurring in patients with other predisposing conditions. We report 4 additional cases of arterial thromboses in 1 lymphoma and 3 myeloma patients treated with thalidomide.
