Chronic sclerodermic graft-versus-host disease refractory to immunosuppressive treatment responds to UVA1 phototherapy.

Graft-versus-host disease is a frequent complication of allogenic bone marrow transplantation. Approximately 10% of patients suffering from chronic graft-versus-host disease develop sclerodermic graft-versus-host disease of the skin, which often does not respond to conventional immunosuppressive therapy. An alternative to immunosuppressive treatment is photochemotherapy. We describe a patient with chronic sclerodermic graft-versus-host disease who did not respond to a combination therapy of cyclosporine and prednisone and later mycophenolate mofetil plus prednisone. A combination therapy of mycophenolate mofetil (2 g/day) and low-dose UVA(1) therapy (single dose, 20 J/cm(2), 4 times per week over 6 weeks) resulted in striking clinical improvement of sclerodermic graft-versus-host disease.
