Beclometasone dipropionate: a topically active corticosteroid for the treatment of gastrointestinal graft-versus-host disease

Current practice in diagnosis and treatment of acute graft-versus-host disease: results from a survey among German-Austrian-Swiss hematopoietic stem cell transplant centers

To assess current clinical practice in diagnosis and treatment of acute graft-versus-host disease (aGVHD), we performed a survey among German, Austrian, and Swiss allogeneic hematopoietic stem cell transplantation (allo-HSCT) centers. Thirty-four of 72 contacted centers (47%) completed both the diagnostic and therapeutic sections of the survey, representing 65% of allo-HSCT activity within the participating countries in 2011. Three pediatric centers answered as requested only the diagnostic part of the survey. In the presence of diarrhea and decreased oral intake after engraftment, only 4 centers (12%) do not perform any endoscopy before the start of immunosuppressive treatment. In case of a skin rash with the differential diagnosis of drug reaction, only 12 centers (35%) perform a skin biopsy up front, whereas 19 do so after failure of systemic steroids. In the presence of rapidly increasing cholestasis occurring without any other signs of aGVHD, 11 centers (32%) perform a liver biopsy up front and 14 only after failure of steroid treatment, whereas 9 centers do not perform a liver biopsy at all. Twenty centers (59%) use a percutaneous approach, 12 a transvenous approach, and 1 mini-laparoscopy for liver biopsies. First-line treatment of cutaneous aGVHD stage 1 consists of topical treatment alone in 17 of 31 responding centers (61%), whereas isolated cutaneous aGVHD stage III is treated with systemic steroids (prednisolone below 0.5 mg/kg/day n = 2, 0.5 to 1.0 mg/kg/day n = 10, above 1.0 to 2.5 mg/kg/day n = 19) without or with topical agents (steroids n = 10; calcineurin inhibitors n = 3). In gastrointestinal manifestations of aGVHD, 9 centers (29%) add topical to systemic steroids, and 3 consider topical steroids as the only treatment for mild gastrointestinal and cutaneous aGVHD. The choice of agent for second-line treatment as well as the sequence of administration are extremely heterogeneous, most likely due to a lack of convincing data published. Most frequently used are mycophenolate mofetil (n = 14) and extracorporeal photopheresis (n = 10). Our survey also demonstrates that clinicians chose salvage therapies for steroid-refractory aGVHD based on their centers' own clinical experience.

The role of oral beclometasone dipropionate in the treatment of gastrointestinal Graft-versus-Host Disease

Graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation causes significant morbidity and mortality. An important site of GVHD is the gastrointestinal (GI) tract because development of acute GI GVHD is prognostic of overall survival. The standard of care to treat acute GI GVHD is systemic corticosteroids and immunosuppressants; however, the use of these therapies can cause life-threatening opportunistic infections. To limit the adverse effects of systemic immunosuppression, the topically active corticosteroid beclometasone dipropionate has been investigated in case studies and in randomized placebo-controlled trials for the treatment of acute GI GVHD. In this review, we appraise these studies with beclometasone dipropionate, and discuss future randomized studies to clarify the role of beclometasone dipropionate for the treatment and prevention of acute GVHD. At present, more data are required before the addition of beclometasone dipropionate to systemic corticosteroids for the treatment of acute GVHD can be considered the standard of care.
