Fifty patients with plaque psoriasis were treated with dithranol and UVB 5 days per week. Twenty-six of these patients also received 13 treatments (once daily in the 1st week, every other day in the 2nd week, twice in the 3rd week and once in the 4th week) with topical clobetasol propionate. The median time for clearance was 2.5 weeks for those on the clobetasol propionate-dithranol-UVB combination compared with 4 weeks when only dithranol-UVB was used. Scaling and induration of the lesions disappeared during the first 2 weeks of treatment with clobetasol propionate-dithranol-UVB which was a significant improvement compared with dithranol-UVB alone. The time of remission in patients completely cleared was the same in the two groups. Relapses occurred slightly more often in the clobetasol propionate treated than in the control group (during treatment 5 of 26 versus 2 of 24; after 6 months 7 of 18 versus 4 of 15) but the differences were not statistically significant. The study shows that addition of topical clobetasol propionate according to our schedule to the traditional dithranol-UVB regimen of psoriasis results in a more rapid clearance of lesions without undesirable side effects.
