The effect of HESA-A on psoriasis vulgaris.

BACKGROUND

Psoriasis vulgaris is one of the most common chronic skin disorders without any curative treatment. The aim of this study was to investigate the efficacy and safety of HESA-A in the treatment of psoriasis.

METHODS

In a randomized, double-blind clinical trial, 28 patients (11 male, 17 female) with chronic plaque-type psoriasis were randomly assigned to treatment and placebo groups. Patients in treatment group received HESA-A tablet 25 mg/kg twice a day orally and control group received placebo with the same method for 6 months and were followed clinically during the study.

RESULTS

At the end of study, in the treatment group psoriatic plaques were absent (no evidence of psoriasis or complete remission) in 9 cases (64.2%) and was very mild (controlled, but not entirely cleared) in 5 cases (35.8%). Disease relief was observed in 10 (71.4%) patients after 4 months, in 2 cases (14.3%) after 5 months and in 2 (14.3%) other patients after 6 months while none of the controls showed disease improvement.

CONCLUSION

This study showed rapid and good efficacy and safety of HESA-A in the treatment of plaque-type psoriasis.
