title: Photochemotherapy of psoriasis.
abstract: Orally administered 8-methoxypsoralen followed by irradiation with longwave ultraviolet light (UVA, 320-400 nm, maximum 365 nm) resulted in 90-100% clearing in 24 of 26 psoriasis patients. Recurrence could be prevented by maintenance treatment. The treatment was tolerated well; no serious side effects were observed. A moderate increase of serum transaminase values was observed in 6 patients; in 5, these values became normal in a short time. The connection between these enzyme increases and the treatment is uncertain. At completion of the treatment the skin is universally, evenly hyperpigmented-a side effect considered positive by the patients.
