Efficacy of combined liman peloid baths and heliotherapy in the treatment of psoriasis at Cervia spa, Emilia, Italy


This study assessed the effects of liman peloid, followed by bath and heliotherapy in psoriatic patients at Cervia, Emilia, Italy. The psoriatic patients were randomized into two groups: group 1 with 56 patients, treated with liman applications, bath, and heliotherapy, and group 2 with 35 subjects, treated with mud-bath therapy using a clay peloid mixed with tap water and heliotherapy. Data was collected for the following: psoriasis area and severity index (PASI); delta-PASI (difference between post- and pre-treatment PASI); delta-PASI3 and delta-PASI6, 3 and 6 months after the end of treatment, respectively; psoriasis recurrences; and the use of both topical and systemic drugs. Although not significant, a decrease in PASI was recorded in group 1 at the end of treatment and after 3 and 6 months. Compared with group 2, there was a significant change in delta-PASI, delta-PASI3, and psoriasis recurrences in group 1 as well as a significant reduction in the topical use of drugs, both cortisone and nonsteroid drugs. This is the first and preliminary study which documented the efficacy of a specific protocol of liman bath heliotherapy in psoriatic patients as documented by a reduction in delta-PASI and delta-PASI3, a decrease in psoriasis recurrences, and use of topical drugs.
