About this study

Official title: POTS-CFS Study: A Case-Control Study on Exertion and Orthostatic Intolerance in the Context of Pediatric ME/CFS

Pilot-case-control study on exertion and orthostatic intolerance of adolescents with myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS) compared to age-matched healthy controls (HC).

Read the detailed description

ME/CFS is a complex disease. Symptoms include orthostatic intolerance (OI) such as postural tachycardia syndrome (PoTS). PoTS in ME/CFS can significantly impair everyday function and social participation. Yet, data in affected adolescents are rare and inconsistent.

This pilot-case-control study study aimed at characterizing OI in adolescents aged 14-17 years with ME/CFS and age-adapted HC, comparing the results with other clinical features of both such as exertion intolerance, fatigue, and health-related quality of life, and suggesting a standardized tool for diagnostics.

ME/CFS was diagnosed according to the Clinical Canadian Criteria (CCC 2003), criteria of the former Institute of Medicine (IOM 2015), the diagnostic work sheet developed by Rowe 2017, and/or the pediatric case suggested by Jason 2006. Questionnaires were used to evaluate symptoms (e.g. post-exertional malaise, fatigue, anxiety, depression), and health-related quality of life. A standardized specific interview was performed to assess the medical history of OI (HOI). Heart rate (HR) and blood pressure were evaluated every minute during a passive 10-min standing test (NASA lean test) in the morning with empty stomach and without morning medication.

Data were evaluated according to the PoTS criteria defined in 2019 at the National Institutes of Health Expert Consensus Meeting and by the International Classification of Diseases (ICD-11) (8D89.2). Frequency and type of OI, including PoTS, were examined in both groups and outcomes compared to parameters from questionnaires. Based on the results, novel standards for OI diagnostics were suggested.

  8. Presence of ME/CFS-specific Symptoms (Munich Berlin Symptom Questionnaire)

    Questionnaire: number of relevant symptoms. Likert Scale "0-4" of severity and frequency for each symptom: A symptom is relevant with a severity and frequency of each at least "2" on the Likert Scale. Minimum: 0 relevant symptoms (best), Maximum: 60 relevant symptoms (worst).

    Measured: one time point during study from study start until study completion, approximately 1 year

  9. Presence of Post-exertional malaise (DePaul Symptom Questionnaire -Post exertional Malaise: DSQ-PEM)

    Questionnaire, Binary Outcome: Post-exertional Malaise Yes/No

    Measured: one time point during study from study start until study completion, approximately 1 year

  10. Self-estimated level of Quality of Life: EQ-5D-5L: Index

    Questionnaire: Index (0 worst - 1 best)

    Measured: one time point during study from study start until study completion, approximately 1 year

  11. Self-estimated level of Quality of Life: EQ-5D-5L: Visual Analog Scale

The record says: finished, as of the sponsor's last update on 26 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Heart Rate during Passive 10-min. standing test (time frame: one time point during study from study start until study completion, approximately 1 year). The study lists 13 primary outcomes in all. 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 26 Sep 2023.
