A COMPARISON OF THE EFFICACY AND RELAPSE RATES OF NARROW-BAND UVB (TL-01) MONOTHERAPY VS ETRETINATE (RE-TL-01) VS ETRETINATE-PUVA (RE-PUVA) IN THE TREATMENT OF PSORIASIS PATIENTS

Forty-five patients with extensive chronic plaque or guttate psoriasis were treated with either narrowband (TL-01) phototherapy, etretinate TL-01 combination therapy (re-TL-01) or etretinate and PUVA (re-PUVA) (15 patients in each group). Re-PUVA was the most effective therapy with 100% satisfactory clearance rate. TL-01 monotherapy had an 80% success rate; the relapse rate compared favourably with re-PUVA (50% in remission after 6 months). In the etretinate-TL-01 group, there was a 93% success rate and a one-third reduction in the total irradiation dose (8.0 J/cm2 vs. 12.7 J/cm2) but the relapse rate was higher, only 33% remaining in remission after 6 months.
