SUMMARY Eighty ambulatory adult patients with severe psoriasis were included in our 14‐week study to compare the clinical effects of treatment with an aromatic retinoid (Tigason), combination treatment with aromatic retinoid plus PUVA (RePUVA), and PUVA alone. RePUVA was given by two different modifications: either 4 weeks of pretreatment with retinoid followed by 6 weeks of PUVA treatment, or 10 weeks of retinoid treatment with concomitant PUVA treatment during the last 6 weeks. The latter modification of RePUVA proved to be significantly more effective than the other treatments ( P <0.01) as regards complete remission. With respect to the number of patients with good or excellent improvement (75–100% improvement) there was no marked difference between RePUVA and PUVA treatments. Retinoid alone proved to be the least effective, showing, however, a good to excellent result in 65% of patients. Besides the increase in efficacy, another advantage achieved by RePUVA was a highly significant ( P <0.001) reduction of total UVA doses to about one third as compared to PUVA therapy.
