About this study

Official title: Impact of Regular Consumption of Eggs and Nutrients Fortified Eggs on Eczema Condition in Singapore Individuals With Eczema

The study aims to assess the effects of daily consumption of nutrients-fortified eggs on eczema condition in Singapore individuals with eczema. The investigators hypothesize that egg consumption will improve eczema condition and nutrients fortified egg consumption will improve further improvements when compared to standard egg consumption in individuals with eczema

Read the detailed description

This is a double-blind, randomized, parallel study and all subjects will complete a 12-week study period. Subjects will be tasked to consume nutrients-fortified eggs and regular eggs daily for 12 weeks. After which, subjects are assessed for changes in carotenoid status, antioxidant and anti-inflammatory biomarkers, skin and eye health measurements, and other biomarkers of health.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Skin questionnaires - SCORing Atopic Dermatitis (SCORAD) Index

    SCORing Atopic Dermatitis (SCORAD) Index is a clinical tool used to assess the severity of atopic dermatitis (AD), also known as eczema. This index can estimate participants' body surface area affected by burns (extent - A: percentage of body surface area affected), Intensity (B: clinical signs are assessed and scored on a scale from 0 (absent) to 3 (severe)), Subjective Symptoms (C: itch, sleep disturbance are evaluated based on the participants' report over the past three days, each scored on a scale from 0 (no symptom) to 10(severe symptom)).

    The SCORAD index is calculated using the following formula:

    SCORAD=A/5+7B/2+C

    Interpretation Mild atopic dermatitis: SCORAD < 25 Moderate atopic dermatitis: SCORAD 25-50 Severe atopic dermatitis: SCORAD > 50

    Measured: Week 0, week 3, week 6, week 9, week 12

  2. Skin questionnaires - Eczema Area and Severity Index (EASI) scoring system

    EASI evaluates the extent and severity of eczema in four body regions: the head and neck, the trunk, the upper limbs, and the lower limbs.

    The EASI score ranges from 0 to 72, with higher scores indicating more severe eczema:

    0: No eczema 1-7: Mild eczema 8-21: Moderate eczema 22-50: Severe eczema 51-72: Very severe eczema

    Measured: Week 0, week 3, week 6, week 9, week 12

  3. Skin questionnaires - Dermatology life quality index (DLQI)

    DLQI is a dermatology-specific instrument used to measure the impact of skin diseases on patients' quality of life. Which assessed disease impact, monitor treatment effectiveness, guide clinical decision-making.

    Interpretation of Scores:

    0-1: No effect on patient's life 2-5: Small effect on patient's life 6-10: Moderate effect on patient's life 11-20: Very large effect on patient's life 21-30: Extremely large effect on patient's life

    Measured: Week 0, week 3, week 6, week 9, week 12

  4. Skin measurement - eczema related

    Skin hydration - units arbitrary Corneometer®. Transepidermal water loss - units gram/hour. Sebum level - unit µg/cm2. Skin pH level - skin pH meter. Skin tape stripping: stratum corneum components assessed by immune dot blots

    Measured: Week 0, week 3, week 6, week 9, week 12

  5. Skin carotenoids status

    Skin carotenoids concentration can be measured by Resonance Raman Spectroscopy, unit is skin carotenoid score, higher score means optimal, lower score means poor condition of skin carotenoids.

    Measured: Week 0, week 3, week 6, week 9, week 12

  6. Blood carotenoids levels

    Blood carotenoids levels can be measured by High-Performance Liquid Chromatography, unit is μmol/L.

    Measured: Week 0, week 6, week 12
