Photochemotherapy in treatment of psoriatic variants.

Our procedure for treating psoriatic variants--psoriasis pustulosa generalisata (PPG) and psoriasis erythrodermica (PE)--was based on the following points: (a) to quickly obtain a good tolerance level to photochemotherapy (PUVA) by applying corticosteroids and/or methotrexate (MX); (b) to discontinue the application of systemic drugs with the help of photochemotherapy, and (c) to maintain the improved condition by applying radiation in gradually prolonged intervals, thus enabling the biologic forces of the organism to participate, undisturbed by drugs, in the healing process. In some PE cases, sole PUVA therapy was sufficient, while in others small doses of MX were added to maintain the improved condition. In PPG, skin manifestations completely disappeared and general symptoms were calmed in the first application of this combined therapeutic procedure. However, in the later relapses PUVA had little share in such a combined treatment.
