The British Journal of Dermatology
|December 1, 1988
Summary
Ultraviolet B (UVB) phototherapy significantly improved atopic dermatitis symptoms compared to placebo. Different UVB dosages showed no significant difference in treatment efficacy for this skin condition.
Area of Science:
- Dermatology
- Phototherapy
- Medical Research
Background:
- Atopic dermatitis is a chronic inflammatory skin condition.
- Phototherapy is a treatment modality for various skin diseases.
Purpose of the Study:
- To evaluate the efficacy of ultraviolet B (UVB) phototherapy in treating atopic dermatitis.
- To compare UVB phototherapy against a visible light placebo.
- To assess different UVB dosage regimens.
Main Methods:
- Two paired-comparison studies were conducted.
- Study I: 17 patients received UVB on one body half and visible light (placebo) on the other for 8 weeks.
- Study II: 25 patients received two different UVB doses (0.8 MED vs. 0.4 MED) on separate body halves for 8 weeks.
Main Results:
- UVB therapy significantly improved atopic dermatitis severity, pruritus, and overall evaluation compared to placebo (P < 0.001).
- 13 out of 17 patients showed considerable improvement or healing on the UVB-treated side.
- No statistically significant difference was found between the 0.8 MED and 0.4 MED UVB dosage regimens.
Conclusions:
- UVB phototherapy is an effective treatment for atopic dermatitis.
- Further research may be needed to determine optimal UVB dosing, as tested regimens showed similar outcomes.
