Abstract: | Background: Numerous studies have confirmed the short‐term effectiveness of 8‐methoxypsoralen bath PUVA therapy in patients with chronic palmoplantar dermatoses; however, little is known about long‐term results. Patients and methods: In this retrospective study we examined the long‐term results in 79 patients (mean age: 48 years) with chronic palmoplantar dermatoses who were treated with bath PUVA three times a week over an 8‐year period. A good clinical response (a reduction of more than 50% of the skin lesions) occurred after a mean of 23 treatments and a mean cumulative UVA dose of 39 J/cm2 in 51 patients (65%). In 2007 a questionnaire was sent to these 51 patients to assess the long‐term outcome. Results: With bath PUVA treatment, the best results were found in patients with hyperkeratotic eczema (17/22; 77% good clinical response) followed by patients with palmoplantar psoriasis (26/41; 63%) and patients with dyshidrotic eczema (8/16; 50%). Thirty‐four patients (67%) answered the questionnaire after a mean follow‐up interval of 4.3 years (10–87 months). Among these patients, 36% reported an improved course of disease after PUVA therapy with reduced frequency and/or intensity of the skin rash, and 29% of patients reported continued complete clearance. 79% of our patients reported a long‐term reduction in the use of topical corticosteroids during the follow‐up period (mean: 4.3 years). In addition, 67% of patients reported a lasting improvement in quality of life. Conclusions: These data show that bath PUVA may have a long‐term, beneficial influence on the course of disease in a majority of patients with recalcitrant chronic palmoplantar dermatoses. |
