What is being measured

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

  1. Percentage of patients with fibromyalgia among patients with ADHD and no prior methylphenidate treatment

    Comparison of the observed prevalence of fibromyalgia (as assessed by the ACR diagnostic criteria) among patients with ADHD (as assessed by the DIVA-5 diagnostic interview) and no prior methylphenidate treatment versus the theoretical prevalence of fibromyalgia in the overall French population

    Measured: Baseline

Secondary outcomes (10)
  1. Percentage of patients with fibromyalgia among patients with ADHD and a current methylphenidate treatment

    Comparison of the observed prevalence of fibromyalgia (as assessed by the ACR diagnostic criteria) among patients with ADHD (as assessed by the DIVA-5 diagnostic interview) and a current methylphenidate treatment versus the theoretical prevalence of fibromyalgia in the French overall population

    Measured: Baseline

  2. Comparison of the levels of cytokines (specific biomarkers of inflammation), between patients with fibromyalgia without ADHD

    Plasma and urine levels of different cytokines (IFN-gamma, IL-1B, IL-6, IL10, IL-13, IL-17, TNF-alpha), as assessed by metabolomic analyses (high-performance liquid chromatography)

    Measured: Baseline

  3. Comparison of the levels of cytokines (specific biomarkers of inflammation), between patients with ADHD without fibromyalgia

    Plasma and urine levels of different cytokines (IFN-gamma, IL-1B, IL-6, IL10, IL-13, IL-17, TNF-alpha), as assessed by metabolomic analyses (high-performance liquid chromatography)

    Measured: Baseline

  4. Comparison of the levels of cytokines (specific biomarkers of inflammation), between patients with fibromyalgia with ADHD

    Measured: Baseline

  5. Comparison of the levels of neuro-inflammation biomarkers (i.e., tryptophane derivatives, short carbon chain fatty acids, lipidomic profile) between patients with fibromyalgia without ADHD,

    Plasma and urine levels of tryptophane derivatives, short carbon chain fatty acids and lipidomic profile, as assessed by metabolomic analyses

    Measured: Baseline

  6. Comparison of the levels of neuro-inflammation biomarkers (i.e., tryptophane derivatives, short carbon chain fatty acids, lipidomic profile) between patients with ADHD without fibromyalgia

    Plasma and urine levels of tryptophane derivatives, short carbon chain fatty acids and lipidomic profile, as assessed by metabolomic analyses

    Measured: Baseline

  7. Comparison of the levels of neuro-inflammation biomarkers (i.e., tryptophane derivatives, short carbon chain fatty acids, lipidomic profile) between patients with fibromyalgia with ADHD

    Measured: Baseline

  8. Comparison of the levels of 500 biomarkers of neurotransmission between patients with fibromyalgia without ADHD

    Plasma and urine levels of 500 different biomarkers of neurotransmission (e.g., dopaminergic, serotoninergic, noradrenegic), as assessed by metabolomic analyses (high-performance liquid chromatography)

    Measured: Baseline

  9. Comparison of the levels of 500 biomarkers of neurotransmission between patients with: ADHD without fibromyalgia

    Plasma and urine levels of 500 different biomarkers of neurotransmission (e.g., dopaminergic, serotoninergic, noradrenegic), as assessed by metabolomic analyses (high-performance liquid chromatography)

Questions about this trial

What is this clinical trial studying?

A study testing Samples, Questionnaires and Sensitivity to mechanical pain in people with ADHD - Attention Deficit Disorder With Hyperactivity and Fibromyalgia (FM), run by University Hospital, Tours.

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 16 inclusion and 7 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: opening soon, as of the sponsor's last update on 4 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 Paul BRUNAULT (02 18 37 05 81, paul.brunault@univ-tours.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients with fibromyalgia among patients with ADHD and no prior methylphenidate treatment (time frame: Baseline). 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 4 Jun 2026.
