BACKGROUND: Chronic graft-versus-host disease is a severe complication of allogeneic stem cell and bone marrow transplantation. First-line immunosuppressive agents, such as steroids, are used to prevent this disease; however, they have multiple side effects. Therefore, bath psoralen plus ultraviolet-A (PUVA) is an alternative second-line treatment. This study aimed to evaluate the clinical efficacy of bath PUVA for managing chronic graft-versus-host disease.
METHODS: This retrospective, case-control study included 14 patients with extensive cutaneous chronic graft-versus-host disease, resistant to systemic corticosteroid, treated with bath PUVA. Major and partial responses were defined as clinical improvements of >70% and 50-70%, respectively. We analyzed the graft-versus-host disease clinical presentation and timing after allogeneic stem cell and bone marrow transplantation, bath PUVA doses, background diseases, additional treatments, and adverse effects.
RESULTS: We observed eight major (three lichenoid and five sclerodermatoid) and six partial (three lichenoid and three sclerodermatoid) responses after a mean of 28 treatment sessions. After 6 to 25 months, four of the eight patients with sclerodermatoid lesions and all those with lichenoid lesions experienced relapse but responded to additional treatment cycles.
CONCLUSIONS: Bath PUVA is well-tolerated and effective for extensive cutaneous chronic graft-versus-host disease. It allows rapid tapering of adjuvant immunosuppressants; however, most patients require prolonged maintenance phototherapy.
