About this study

We aim to assess the influence of chronic insomnia on the neuroendocrine regulation of the glucose and lipid metabolism to more clearly define the metabolic derangements associated with chronic insomnia and to prove that chronic insomnia is associated with increased levels of stress hormones, cytokines and impaired insulin sensitivity.

Read the detailed description

Sleep fragmentation has previously been shown to result in activation of the stress axis as indicated by enhanced cortisol and catecholamine release and a proinflammatory state mirrored by increased concentrations of proinflammatory cytokines such as IL-6 and TNFa. Therefore sleep deprivation is associated with a similar pattern of endocrine and proinflammatory alterations that may promote the insulin resistant state. Thus, it is of paramount interest to clearly define the metabolic alterations in patients with primary insomnia.

Patients with with suspected primary insomnia will be recruited from the sleep clinic at the University Hospital Basel and by newspaper ads. Primary insomnia will be diagnosed by a polysomnographic study and the exclusion of secondary causes such as depression, sleep apnea and restless legs syndrome. Eligible patients will be admitted to the CRC for metabolic studies, including baseline blood samples for the measurement of hormones, cytokines and adipokines, a euglycemic-hyperinsulinemic clamp study for the assessment of glucose turnover and insulin sensitivity and in vivo NMR studies to determine intrahepatic and intramyocellular lipid content.

The data obtained in insomnic patients will be compared to those of a control group matched for age, sex, BMI, menopausal status and physical activity selected from the general population.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Insomnia, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 12 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 9 Mar 2012. 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 Switzerland. 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.

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 9 Mar 2012.
