Adding Auricular Acupuncture to Xiao-Feng-San Decoction for Treating Atopic Dermatitis

Efficacy of Adding Auricular Acupuncture to Xiao-Feng-San for Treating Atopic Dermatitis Exhibiting Wind-Dampness-Heat Manifestations According to Traditional Medicine: A Multi-Center, Double-Blinded, Randomized, Sham-Controlled Trial

This study aims to compare the efficacy of adding auricular acupuncture to Xiao-Feng-San decoction versus Xiao-Feng-San decoction in treating atopic dermatitis. The trial is a multi-center, double-blinded, randomized, sham-controlled study.

Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects a significant number of individuals worldwide. In Traditional Medicine (TM), Xiao-Feng-San (XFS), a TM formula, has been widely used in the treatment of mild to moderate AD exhibiting wind-dampness-heat manifestations. This study aims to investigate whether the addition of auricular acupuncture (AA), a form of acupuncture targeting points on the ear, enhances the efficacy of XFS in treating AD.

The trial is a multi-center, double-blinded, randomized, sham-controlled study involving participants diagnosed with mild to moderate AD exhibiting wind-dampness-heat manifestations according to TM and indicated for the use of XFS decoction. Participants will be randomly assigned to receive either AA or sham AA (placebo) in addition to XFS. Outcome measures will include the severity of AD symptoms, quality of life assessments, the need for antipruritic medication, total serum immunoglobulin E (IgE) levels, and adverse effects.

Through rigorous methodology and blinding procedures, this study seeks to provide evidence on the comparative efficacy of adjunct AA in enhancing the therapeutic effects of XFS for AD. The findings aim to contribute valuable insights into optimizing treatment strategies for AD using integrative approaches.

Inclusion Criteria:

Exclusion Criteria:

• Presence of other active skin diseases or skin infections requiring systemic treatment within the past four weeks or that would interfere with the proper assessment of atopic dermatitis lesions.
• Use of systemic therapy for AD, including but not limited to corticosteroids, methotrexate, cyclosporine, azathioprine, phosphodiesterase type 4 (PDE4) inhibitors, interferon-gamma (IFN-γ), and mycophenolate mofetil within the past four weeks.
• Use of targeted biologic treatments within the past five half-lives (if known) or within the past 12 weeks, whichever is longer.
• Use of phototherapy treatment, laser therapy, tanning booth sessions, or extended sun exposure that could affect disease severity or interfere with disease assessments within the past four weeks.
• Use of systemic anti-infectives within the past four weeks.
• Use of herbal medicine within the past 12 weeks.
