Modified Huang-Lian-Jie-Du Decoction (MHLJDD) for Atopic Dermatitis in Children
Study Details
Study Description
Brief Summary
The study aims to evaluate the clinical efficacy of Chinese medicine (CM) for the treatment of subacute and chronic Atopic Dermatitis (AD) patients when compared to the placebo control by examining the clinical symptoms.

Phase 1/Phase 2 |
Detailed Description
This is a parallel, randomized, placebo-controlled, double-blind pilot study. The subjects will come for a screening visit at week 0 (baseline), then at week 6±3 days, week 12±3 days and week 16±4 days for Chinese medicine practitioner (CMP) investigators' assessments (Fig 1). Eczema Area and Severity Index (EASI), Children's dermatology life quality index (CDLQI), and Patient-Oriented Eczema Measure (POEM) will be assessed and filled up at different time points. Eligible subjects will be randomly allocated to the treatment group receiving oral CM granules or the placebo control group receiving oral placebo granules for 12 weeks, and then be followed up 4 weeks after the treatment.

Outcome Measures
Primary Outcome Measures
- EASI score [12 weeks]
The change of EASI score for atopic dermatitis at week 12 Min value: 0, max value: 72, higher scores mean worse outcome. To assess the severity of atopic dermatitis.
Secondary Outcome Measures
- EASI score [6 weeks]
The change of EASI score for atopic dermatitis at week 6 Min value: 0, max value: 72, higher scores mean worse outcome. To assess the severity of atopic dermatitis
- EASI score [16 weeks]
The change of EASI score for atopic dermatitis at week16 Min value: 0, max value: 72, higher scores mean worse outcome. To assess the severity of atopic dermatitis
- CDLQI score [12 weeks]
The change of CDLQI score at week 12 Min value: 0, max value: 30, higher scores mean worse outcome. To assess the quality of life of subjects.
- CDLQI score [16 weeks]
The change of CDLQI score at week 16 Min value: 0, max value: 30, higher scores mean worse outcome. To assess the quality of life of subjects.
- POEM score [12 weeks]
The change of POEM score at week 12 Min value: 0, max value: 28, higher scores mean worse outcome. To assess the subjective symptoms of subjects.
- POEM score [16 weeks]
The change of POEM score at week 16 Min value: 0, max value: 28, higher scores mean worse outcome. To assess the subjective symptoms of subjects.
- Microbiome [12 weeks]
The change of microbiome at week 12. The oral and gut microbiota are the collection of microbial agents such as bacteria, viruses and fungi that inhabit in the mouth cavity and gut. Bacterial microbiome sequencing is performed using 16S ribosomal RNA pyrosequencing.
- Time of flare [16 weeks]
The time to reach flare (defined as major exacerbation disease increase > 50% of baseline EASI)
- The number of subjects reaches flare [16 weeks]
The number of subjects reaches flare (defined as major exacerbation disease increase > 50% of baseline EASI)
- Trans-epidermal water loss (TEWL) [6 weeks]
Trans-epidermal water loss (TEWL) at week 6 The Trans-epidermal water loss (TWEL) is measured in g/m2h, which range from 0 to 300. An increasing TEWL value indicates greater skin dryness.
- Trans-epidermal water loss (TEWL) [12 weeks]
Trans-epidermal water loss (TEWL) at week 12 The Trans-epidermal water loss (TWEL) is measured in g/m2h, which range from 0 to 300. An increasing TEWL value indicates greater skin dryness.
- Trans-epidermal water loss (TEWL) [16 weeks]
The change of trans-epidermal water loss (TEWL) at week 16 The TWEL is measured in g/m2h, which range from 0 to 300. An increasing TEWL value indicates greater skin dryness.
- Skin hydration (SH) [6 weeks]
The change of skin hydration (SH) at week 6 The SH is measured in arbitrary units (a.u.), which range from 0 to 300 a.u.
- Skin hydration (SH) [12 weeks]
The change of skin hydration (SH) at week 12 The SH is measured in arbitrary units (a.u.), which range from 0 to 300 a.u.
- Skin hydration (SH) [16 weeks]
The change of skin hydration (SH) at week 16 Skin hydration will be measured topically using the measuring device at a standard site below the antecubital fossa of each patient's right arm. The SH is measured in arbitrary units (a.u.), which range from 0 to 300 a.u.
- Adverse event [16 weeks]
Adverse event will be assessed in the study period
