Beneficial Effects of Paraffin Bath Therapy as Additional Treatment of Chronic Hand Eczema: A Randomized, Single-Blind, Active-Controlled, Parallel-Group Study.

Objective: Chronic hand eczema (CHE) is a common inflammatory skin disease with a major psychological and socioeconomic impacts on patients' quality of life (QoL) and work ability. To the best of knowledge, this study is the first randomized-controlled trial conducted to evaluate the effect of paraffin bath therapy in management of hand eczema and its related symptoms. Design: This study was a parallel-group, active-control, randomized clinical trial with measures at pretreatment, 6th week, and 12th week of treatment. Settings: The study took place at the Outpatient Clinic of Faculty of Physical Therapy, Cairo University, and some licensed rehabilitation centers in Cairo for a 1-year period. Subjects: Sixty patients with moderate to severe CHE were randomly assigned into two groups of equal number; the paraffin bath therapy group and the control group. Interventions: The paraffin group received paraffin bath therapy for 5 days a week for 12 weeks, in addition to the routine skin care program, while the control group only received the routine skin care program. Outcome measures: SCORing Atopic Dermatitis (SCORAD) was used to assess the severity of atopic dermatitis and dermatology life quality index (DLQI) to assess the effect of CHE on quality of patients' life. All measurements were obtained before, at the 6th week, and at the 12th week of treatment. Results: Marked improvement in the severity of the disease symptoms was observed, reflected by a highly decrease in objective SCORAD score in the paraffin group over time more than the control group. The percentage of reduction was 28.6% in paraffin group versus 0.41% in control group. Subjective item score (itching and sleepiness) was reduced in the paraffin group more than the control group with a percentage of improvement (47% and 5.5%), respectively. Regarding QoL measure, there were highly positive changes in DLQI in paraffin group more than the control group. The percentage of improvement was 60% in paraffin group and 3.8% in control group. Conclusions: Paraffin bath therapy applied for a 12-week duration seems to be effective, both in reducing severity of eczema symptoms and improving QoL in patients with CHE. [ABSTRACT FROM AUTHOR]
