Study summary

Dysautonomia in post-covid-19 condition appears to affect a significant number of patients, with reports raising the incidence up to 61%, having an overlap with myalgic encephalomyelitis/ chronic fatigue syndrome. Quality of life and daily function is significantly impacted and conservative management interventions, despite the lack of high quality evidence up to now, are needed to ameliorate disability. 50 adults with a dysautonomia post-covid-19 diagnosis based on the Ewing battery and a NASA lean test will be enrolled in a randomized single blinded controlled trial with a crossover design. Feasibility and lack of definite dysautonomia diagnosis will be the primary out-comes, while secondary outcomes will be health-related, clinical and cardiopulmonary exercise test indicators. Safety and acceptance will also be checked, primarily excluding participants with post exertional malaise. The Long-CoViD patients Causal Diagnosis and Rehabilitation study in patients with Dysautonomia (LoCoDiRE-Dys) study intervention will consist of an educational module, breathing retraining and an individualized exercise intervention of biweekly sessions for two months with regular assessment of both groups. LoCoDiRe- Dys aims to be the first post-covid-19 randomized study in people with dysautonomia offering a multimodal intervention both in diagnosis and management

  • Able to provide

Exclusion criteria

Exclusion Criteria:

  • Absolute or relative to exercise due to cardiac pathology
  • Serious mental/ cognitive impairment that will not allow systematic participation
  • Unable to regularly reach the center
  • Pregnancy
  • CFS/ME fulfilling the Canadian Consensus Criteria
  • Secondary health conditions that would explain symptoms, intervene in dysautonomia diagnosis or would impede participation in the exercise protocol (i.e. , untreated hypothyroidism and Diabetes Melitus, major psychiatric disorders, , PICS, Pulmonary Fibrosis, chronic respiratory or heart failure, not ambulatory, suffering from dementia, chronically paralyzed, with paraplegia, with multiple injuries or other serious orthopedic problems that caused disability, patients suffering from very serious underlying diseases such as end-stage cancer, and those with neurological diseases causing disability)
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

What researchers measure

Primary outcomes

  1. Number of patients with lack of definite Dysautonomia Diagnosis

    Ewing Battery is a validated instrument to diagnose dysautonomia, with a definite diagnosis when 2 out of 4 heart rate tests are abnormal

    Time frame: 4 months

  2. Compliance, Adverse Events and Protocol Titration to examine feasibility of the trial

    Process measures that will substantiate offering of the service

    Time frame: 4 months

Secondary outcomes

  1. 10 minutes NASA Lean Test

    Validated measure to record orthostatic intolerance, recording of blood pressure and heart rate in 5 min supine position, and every minute when standing up till 10 min

    Time frame: checked at [0], [8] and [16] weeks

  2. Six minute Walk Test

    Validated measure, a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.

    Time frame: checked at [0], [8] and [16] weeks

  3. 1 minute sit to stand test

    Validated measure to record the times standing up from a chair, closely related with cardiorespiratory capacity and lower limb strength

    Time frame: checked at [0], [8] and [16] weeks

  4. Fatigue Severity Scale

    Validated measure to record fatigue severity as reported by the patient, 9 statements each in a scale of 1-7, min 9 max 63

    Time frame: checked at [0], [8] and [16] weeks

  5. modified Medical Research Council Dyspnea Scale

    Validated measure to record functional disability because of dyspnea as reported by the patient in a scale 0-4

    Time frame: checked at [0], [8] and [16] weeks

  6. Nijmegen Questionnaire

    Validated measure to record dysfunctional breathing as recorded by the patient with each statement valued 0-4, with A score of over 23 out of 64 suggest a positive diagnosis of hyperventilation syndrome.

    Time frame: checked at [0], [8] and [16] weeks

  7. Montreal Cognitive Assessment

  8. International Physical Activity Questionnaire

    Validated measure with 27 item self reporting physical activity of the patient

  9. Hospital Anxiety and Depression Scale

    Validated measure, a 14-item measure designed to assess anxiety and depression symptoms in medical patients. Items are rated on a 4-point severity scale. The HADS produces two scales, one for anxiety (HADS-A) and one for depression (HADS-D), differentiating the two states. Scores of greater than or equal to 11 on either scale indicate a definitive case

  10. EuroQoL 5 Dimensions 5 Levels

    Validated measure, a self-assessed, health related, quality of life questionnaire. The scale measures quality of life on a 5-component scale including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression
