Trial summary

Auto-immune diseases are characterized by an inappropriate inflammatory response against tissues in the body and represent a major health care burden. Pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β play a central role in the pathophysiology of many auto-immune diseases. Read more about this study

About this study

Official title: Concentration/Meditation as a Novel Means to Limit Inflammation: a Randomized Controlled Pilot Study

Auto-immune diseases are characterized by an inappropriate inflammatory response against tissues in the body and represent a major health care burden. Pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β play a central role in the pathophysiology of many auto-immune diseases. Innovative therapies aimed at limiting pro-inflammatory cytokine production in a more physiological manner are warranted. In previous research conducted in an individual known as "the iceman", the investigators found that, through a autodidact concentration/meditation technique, he appears to mount a controlled stress response, characterized by activation of the sympathetic nervous system and enhanced production of cortisol, both of which are known to result in immunosuppression. In accordance, while practicing this concentration/meditation technique, the inflammatory response during human endotoxemia (lipopolysaccharide [LPS] administration) was remarkably low in this individual. Therefore, this technique could provide a novel means of controlling the inflammatory response. However, the aforementioned results were obtained in just one subject, and hence can not serve as scientific evidence for the effectiveness of the concentration/meditation technique. The iceman claims that he can teach this technique to other subjects within a relatively short time frame. Therefore, in the present study the investigators wish to investigate the effect of concentration/meditation on autonomic nervous system activity and the inflammatory response during experimental human endotoxemia in a controlled manner, by comparing a group of subjects that are trained by "the iceman" and practice the concentration/meditation technique with a group of subjects which do not.

What participants receive

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

  • LipopolysaccharideDrug

    Also called Lipopolysaccharide (LPS) E. Coli 113:H 10:K negative

    LPS is used to elicit an inflammatory response in all subjects.

  • Concentration/meditationBehavioural

    Also called Wim Hof Method

    A self-taught concentration/meditation technique that Mr Wim Hof developed himself, characterized by cycles consisting of a few minutes of hyperventilation followed by breath holding for up to 1-2 minutes and deep concentration (mindset).

Questions about this trial

What is this clinical trial studying?

A study testing Lipopolysaccharide and Concentration/meditation in people with Autoimmune Diseases, run by Radboud University Medical Center at 1 site in Netherlands.

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 4 inclusion and 18 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: finished, as of the sponsor's last update on 23 Jul 2013. 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 Netherlands. 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?

Concentration of circulating TNF-α following LPS administration (time frame: 1 day). 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 23 Jul 2013.
