COMPARATIVE THERAPEUTIC EVALUATION OF DIFFERENT TOPICALS AND NARROW BAND ULTRAVIOLET B THERAPY COMBINED WITH SYSTEMIC METHOTREXATE IN THE TREATMENT OF PALMOPLANTAR PSORIASIS

Background: The incidence of uncomplicated psoriasis is 1–3% in the general population. The involvement of palm and sole is seen in 7–14.5% of cases. There are different topicals and systemic therapies available for treating the case of psoriasis but none is satisfactory for longer duration. Aim: The study involved the comparative therapeutic evaluation of the different topical regimens and narrow band ultraviolet B (NB-UVB) therapy in combination with systemic methotrexate. Materials and Methods: The study was held in out-patient department of Skin, VD and Leprosy of B.R.D. Medical College, Gorakhpur, from July 2007 to December 2008. The group included 98 new cases of palmoplantar psoriasis. These cases were divided into eight groups according to the eight regimens involved in the study. The severity of psoriasis was assessed by the ESIF (erythema, scaling, induration and fissuring) score. Results: The study showed that all the regimens had significant response rates. The combination of NB-UVB with systemic methotrexate had maximum response rate (64.85±4.52%) that was statistically significant (paired “t” at 16d.f. = 33.329, P<0.001) with minimum number of recurrences after stopping the treatment. The combination of halobetasol ointment with systemic methotrexate also had significant response rate (paired “t” at 19d.f. = 13.5183, P<0.001) but had maximum number of cases with recurrence (70%) after stopping the treatment. Conclusion: These results suggest that the combination of every regimen with systemic methotrexate resulted in an early and a good improvement in the quality of life of patients suffering from psoriasis. It also shows that NB-UVB in combination with systemic methotrexate is more efficacious and has minimum recurrence rate and side effects in the treatment of palmoplantar psoriasis.
