RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Because of the growing incidence of AD, psychosocial and economic burden of AD patients are often considerable. Steroid treatments are widely used, but long term use of this treatment can cause side effects. To reduce the burden of AD patients and find new efficient treatment, this study chose Soshiho-tang, a traditional medicine used in eastern Asia. AIM OF THE STUDY: Soshiho-tang (SSHT) is a traditional herbal medicine that has anti-inflammatory effects and improves immune function. This clinical trial evaluated the efficacy and safety of SSHT in atopic dermatitis (AD) patients with gastrointestinal disorders in comparison with placebo. MATERIALS AND METHODS: This study was a single-center, randomized, double-blinded, placebo-controlled, and investigator-initiated clinical trial. A total of 60 patients aged 3-18 years with gastrointestinal disorders and diagnosed with AD by Hanifin & Rajka criteria with a Scoring Atopic Dermatitis (SCORAD) index between 15 and 49 were enrolled. Participants were randomly assigned to the SSHT or placebo groups in a ratio of 1:1 and efficacy evaluation was conducted at week 4 and 8. The participants orally administered SSHT or placebo three times a day for 4 weeks. The primary outcome was measured based on a change of SCORAD index. The secondary outcome measurements included the following: survey questionnaires of gastrointestinal disorder, amount and frequency of ointment application for AD, dermatology quality of life index, and safety evaluation (diagnostic test, adverse reaction, and vital sign monitoring). RESULTS: During efficacy evaluation, the SCORAD score and digestive symptoms in the experimental and placebo groups were not statistically significant. However, the amount and frequency of ointment application in the experimental group were reduced compared to those in the placebo group at week 8. Also, In the Children's Dermatology Life Quality Index (CDLQI), statistically significant Quality of Life (QOL) improvement was observed in the SSHT experimental group compared to the placebo group. In safety evaluation, all participants were within the normal range during the study period. Blood sample testing indicated that the lymphocytes ratio decreased, and neutrophils ratio increased in the experimental group, whereas the placebo group showed the opposite immune response pattern. CONCLUSION: We concluded that SSHT administration can reduce steroid ointment dependence and improve the QOL in AD patients by regulating neutrophil-lymphocyte ratio.

BACKGROUND: Atopic dermatitis (AD, atopic eczema) is a pruritic, inflammatory, chronic skin disease. Since there is limitation of conventional treatment of AD, traditional herbal medicine can be an attractive therapeutic option in patients having AD for a long time. So-Cheong-Ryong-Tang (SCRT) has been found to inhibit histamine release and degranulation of mast cells, differentiation of basophils, and proliferation of eosinophils. We designed this clinical trial to evaluate the efficacy and safety of SCRT as compared to placebo in patients with AD and respiratory disorders. METHODS/DESIGN: This study is a single-center, randomized, double-blind, placebo-controlled, and investigator-initiated clinical trial. A total of 60 patients between 7 and 65 years of age with AD and respiratory disorders who received a diagnosis of AD by Hanifin and Rajka criteria who scored 15 to 50 in a scoring atopic dermatitis (SCORAD) will be enrolled. Participants will be randomly assigned to the SCRT or placebo group in a ratio of 1:1 and they will have a visit schedule comprising 4 visits including a screening visit during 8 to 10 weeks. The participants will be administered SCRT or placebo 3 times a day for 4 weeks. The primary outcome will be measured by a change of the SCORAD index. The secondary outcomes will be measured by changes in the dose and frequency of usage of the AD ointment, dermatology life quality index scores, pruritus and sleep disorder in visual analog scale, skin moisture content, skin surface temperature, Hamilton anxiety rating scale scores, depression rating scale scores, stress/autonomic nervous function test, and attention deficit hyperactivity disorder survey scores at week 4 as compared to those at the baseline. DISCUSSION: To the best of our knowledge, SCRT has rarely been reported for dermatologic diseases. This will be the first clinical trial to assess the efficacy and safety of SCRT in patients with AD and respiratory disorders. We hope that the results of this trial will provide evidence for the use of SCRT as a new treatment for AD with respiratory disorders.

Atopic dermatitis is a chronic inflammatory skin disease that affects the growth and development of children. The prevalence of atopic dermatitis has been continually increasing, and this has also been accompanied by rising socioeconomic costs. Interest has been growing in alternative medicine as a means of alleviating the burden of atopic dermatitis. This was a single-center, double-blinded, randomized, placebo-controlled investigator-led clinical trial including 60 atopic dermatitis patients. The participants were classified into an experimental group (30 persons) and a control group (30 persons), who were administered, respectively, socheongryong-tang or a placebo for 4 weeks. After 4 weeks of treatment, the participants visited the trial center again and assess their efficacy and safety. The researchers performed statistical comparisons of the changes in the SCORAD Index, amount and frequency of ointment use, and height and weight to assess the efficacy. To assess the safety, diagnostic tests and vital sign checks were performed at each visit, and the presence or absence of adverse events was observed. As a result, the frequency and the amount of steroid ointment application in both groups increased, but the experimental group showed less tendency (p = 0.081). Results of analyzing the children in the experimental group in relation to growth showed a significantly greater height growth than the control group (p < 0.05). In addition, all study participants did not show any remarkable abnormal signs in the safety evaluation. In conclusion, compared to the control group, the experimental group, who took socheongryong-tang showed a tendency to be less dependent on steroid ointment and statistically significant increase in height.
RESUMEN
BACKGROUND: Atopic dermatitis (AD) is a chronically relapsing inflammatory skin disease that affects the quality of life in patients with AD. Since there is limitation of conventional treatment of AD, complementary treatment is required to treat AD symptoms more effectively and safely Soshiho-tang (SSHT) is a traditional herbal medicine that exhibits anti-inflammatory and anti-ulcer effects and improves the immune function. In this clinical trial, we will evaluate the efficacy and safety of SSHT in patients with AD and gastrointestinal disorders in comparison with placebo. METHODS/DESIGN: This study is a single-center, randomized, double-blind, placebo-controlled, and investigator-initiated clinical trial. A total of 60 patients aged 3 to 18 years with AD and gastrointestinal disorders and who received a diagnosis of AD by Hanifin & Rajka criteria with a Scoring Atopic Dermatitis (SCORAD) index between 15 and 49 will be enrolled. Participants will be randomly assigned to the SSHT or placebo group in a ratio of 1:1. Additionally, they will have a visit schedule comprising 4 visits including a screening visit during 8 to 10 weeks. The participants will be administered SSHT or placebo 3 times a day for 4 weeks. The primary outcome will be measured by a change of the SCORAD index. The secondary outcome measures include the following: survey questionnaires for the perception of gastrointestinal disorders, amount and frequency of ointment usage for AD, dermatology quality of life index, itchiness and sleep disability score in visual analog scale, percutaneous water loss, skin surface temperature, Hamilton anxiety rating scale, and children's depression inventory. DISCUSSION: In our knowledge, this will be the first clinical trial to assess the efficacy and safety of SSHT in patients with AD and gastrointestinal disorders. The findings of this study will provide new treatment options for patients with AD and gastrointestinal disorders.

INTRODUCTION: Several studies have found that obesity is associated with atopic dermatitis (AD); however, the mechanisms underlying the association are largely unknown. This study aims to assess the association of AD with obesity in the Korean population and verify its mechanism via a multi-omics analysis. METHODS AND ANALYSIS: A case-control study will be conducted in the Republic of Korea. A total of 80 subjects, aged 4 to 12 years, matched for age and sex, with body mass index at or above the 85th percentile or at or below the 25th percentile, will be included. Subjects will be assigned to the following 4 groups: obese/overweight with AD, normal/underweight with AD, obese/overweight control, and normal/underweight control. Serum metabolome and immune biomarkers, as well as fecal metabolome and microbiome biomarkers, will be analyzed. Serum eosinophil cationic protein, total serum Immunoglobulin E (IgE), and specific IgE will be analyzed to assess allergic tendency. The SCORing of AD index, the children's dermatology life quality index, body composition analysis, and the Korean gastrointestinal symptom rating scale will be obtained to assess the disease status and severity of the subjects. DISCUSSION: The findings of this study are expected to provide evidence of an association between AD and obesity via a gut microbiome-metabolome-immune mechanism. Therefore, it may improve future management strategies for AD. TRIAL REGISTRATION: This study has been registered at the Korean National Clinical Trial Registry, Clinical Research Information Service (KCT0003630).
