Abstract

Extracorporeal photochemotherapy (EPC) has been used to treat cutaneous T-cell lymphomas as well as a number of immune-mediated disorders. Seven patients above 50 years of age with refractory rheumatoid arthritis (RA) were treated by EPC. Mononuclear cells were harvested, exposed to ultraviolet A light in the presence of 8-methoxypsoralen, then reinfused into the patient. This procedure was repeated eight times over a three-week period. Improvements in clinical parameters were seen in every case as early as the second week and persisted throughout the duration of EPC. Improvements for more than three months were observed in two patients. C-reactive protein levels declined during the treatment period. No adverse reactions were recorded. The mechanism of action of EPC in RA requires elucidation and a controlled study is needed to confirm the efficacy of this technique.
