Trial summary

The prevalence of atopic dermatitis has increased along with urbanization and biodiversity loss. According to biodiversity hypothesis, the main reason is urban lifestyle and reduced contact to microbial diversity. Read more about this study

About this study

Official title: Biodiversity Interventions for Well-being - the Effect of Biodiversity Exposure on Atopic Dermatitis

The prevalence of atopic dermatitis has increased along with urbanization and biodiversity loss. According to biodiversity hypothesis, the main reason is urban lifestyle and reduced contact to microbial diversity. Previous studies indicate association between atopic dermatitis and exposure to natural microbes in childhood.

Sand Play - the Effect of Biodiversity Exposure on Atopic Dermatitis will investigate whether the exposure to microbial diversity in sandbox reduces the symptoms of atopic dermatitis, alters commensal microbiota and modifies immune regulation in children.

Read the detailed description

Our specific aims are:

To assess if exposure to microbial diversity reduces Eczema Area and Severity Index (EASI) and Patient-Oriented Eczema Measure (POEM).

Assess whether the sand play alters plasma cytokine profiles, white blood cell distributions, allergy specific IgE, and commensal microbial communities on skin, in saliva and gut.

The investigators will recruit approximately 80 (40 study subjects per treatment) subjects with atopic dermatitis and aged between 2-5.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Microbial interventionBiological

    Children in microbial intervention arm receive an indoor sandbox containing play sand enriched with organic leaf compost, moss and humus substances. Families also receive an indoor cultivation set including growing box, seeds, spray bottle, plant lamp and microbe rich growing medium containing organic leaf compost, moss, biochar and humus substances.

  • PlaceboOther

    Children in placebo arm receive an indoor sandbox containing visually similar play sand modified with peat with low microbial diversity. Families also receive an indoor cultivation set including growing box, seeds, spray bottle, plant lamp and growing medium containing peat, inorganic fertilizers, and potting gravel with low microbial diversity.

What is being measured

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

  1. Eczema Area and Severity Index (EASI)

    EASI reduced by at least 50% from baseline in microbial intervention treatment. The minimum EASI score is 0 and the maximum EASI score is 72.

    Measured: Baseline, 2 month, 6 month

Secondary outcomes (12)
  1. The Patient-Oriented Eczema Measure

    Lower score on the Patient-Oriented Eczema Measure (POEM) among microbial intervention arm compared to placebo arm after intervention. The total POEM score can range from 0 to 28, with higher scores indicating more severe eczema symptoms.

    Measured: Baseline, 2 month, 6 month

  2. Allergy specific Immunoglobulin E

    It will be analyzed if allergy specific IgE is different between treatments

    Measured: Baseline, 2 month, 6 month

  3. Plasma cytokines

    Cytokines will be analyzed analyzed with Meso Scale.

    Measured: Baseline, 2 month, 6 month

  4. Distribution of white blood cells

    It will be analyzed if the distribution is different between treatments

    Measured: Baseline, 2 month, 6 month

  5. Skin microbiota

    It will be analyzed if skin microbial communities are different between treatments

    Measured: Baseline, 2 month, 6 month

  6. Saliva microbiota

    It will be analyzed if saliva microbial communities are different between treatments

    Measured: Baseline, 2 month, 6 month

  7. Gut microbiota

    It will be analyzed if stool microbial communities are different between treatments

    Measured: Baseline, 2 month, 6 month

  8. Infectious diseases

    Infections will be recorded with questionnaires.

    Measured: Baseline, 2 month, 6 month

  9. Perceived Stress Scale

    Lower score on a perceived stress scale among guardians in intervention arm compared to placebo arm that indicates lower perceived stress levels among guardians in intervention arm. Minimum 0, maximum 40.

    Measured: Baseline, 2 month, 6 month

  10. Warwick-Edinburgh Mental Wellbeing Scale

    Higher score on a Warwick-Edinburhg Mental Wellbeing scale among guardians in intervention arm compared to placebo arm that indicates better mental well-being among guardians in intervention arm. Minimum 14, maximum 70.

    Measured: Baseline, 2 month, 6 month

  11. Depression Scale

    Lower score on a Depression scale among guardians in intervention arm compared to placebo arm that indicates lower levels of depression symptoms among guardians in intervention arm. Minimum 0, maximum 60.

    Measured: Baseline, 2 month, 6 month

  12. Nature Relatedness Scale

    Higher score on a Nature Relatedness scale among guardians in intervention arm compared to placebo arm that indicates stronger sense of connectedness to nature among intervention arm. Minimum 6, maximum 30.

    Measured: Baseline, 2 month, 6 month

Questions about this trial

What is this clinical trial studying?

A study testing Microbial intervention in people with Atopic Dermatitis and Nature, Human, run by Natural Resources Institute Finland at 2 sites in Finland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 30 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Finland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sanna Hurtola (+358295322500, sanna.hurtola@luke.fi), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Eczema Area and Severity Index (EASI) (time frame: Baseline, 2 month, 6 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2024.
