Constant low-dose ultraviolet light therapy for psoriasis

K M Halprin, M Comerford, J R Taylor

    Journal of the American Academy of Dermatology
    |November 1, 1982
    PubMed
    Summary

    A constant low dose of ultraviolet light therapy proved as effective as a standard increasing dose for clearing psoriasis lesions. This finding offers a simpler, potentially safer approach to phototherapy for psoriasis management.

    Area of Science:

    • Dermatology
    • Phototherapy
    • Psoriasis Treatment

    Background:

    • Psoriasis is a chronic autoimmune condition causing skin inflammation.
    • Ultraviolet (UV) light therapy is a common treatment for psoriasis.
    • Standard UV therapy protocols often involve increasing doses.

    Purpose of the Study:

    • To compare the efficacy of a constant low-dose UV therapy with standard increasing-dose UV therapy for psoriasis.
    • To evaluate if a simplified UV dosage regimen can achieve comparable lesion clearance.

    Main Methods:

    • A bilateral comparison study design was employed.
    • Symmetric psoriasis plaques were treated with either a constant low UV dose (3 min 30 sec) or a standard increasing UV dose.
    • Lesion clearance was assessed to determine treatment efficacy.

    Main Results:

    • The constant low dose of UV light demonstrated equivalent efficacy in clearing psoriasis lesions compared to the standard increasing dose.
    • No significant difference in therapeutic outcome was observed between the two UV dosage regimens.

    Conclusions:

    • A constant low dose of ultraviolet light therapy is a viable and effective alternative to standard increasing-dose protocols for psoriasis.
    • This simplified approach may offer benefits in terms of treatment consistency and patient management.
