About this study

The main purpose of this study is to learn about the effects of sleep disruption (two days in a row where sleep is shortened and disrupted) on inflammation, mood (how you feel), and pain processing (your own experiences/perceptions of pain). In this research project, we are trying to figure out if we can change the effects of sleep disruption on inflammation, mood, and pain. Therefore, we will study whether taking a low-dose aspirin pill every day over 2 weeks can change how we respond to sleep disruption. For example, does the sensitivity to pain (e.g., how intense the feeling of pain is if we put our hand in very hot or very cold water) change with sleep disruption, and can low-dose aspirin influence this change. We are also interested in seeing how inflammation changes in relation to your own perceived experience of pain.

Read the detailed description

Sleep that is deficient in quantity or quality leads to upregulation of inflammatory markers (Mullington et al., 2010). In particular, interleukin (IL)-6 and prostaglandin (PG) E2 are elevated in experimental models of sleep restriction or total sleep deprivation, as well as in insomnia. Inflammation is thought to be a key mechanism through which insufficient sleep increases the risk of developing or exacerbating various disorders, including cardiovascular and metabolic disorders (Mullington et al., 2009), as well as pain-related disorders (Haack et al., 2009c). With respect to pain, markers such as IL-6 and PGE2 are able to sensitize pain transmission neurons, thereby increasing their responsiveness to stimulation. In the context of insufficient sleep, both IL-6 and PGE2 have been shown to be associated with increased spontaneous pain (Haack et al., 2007;Haack et al., 2009a), suggesting their mediating role in pain amplification as a consequence of insufficient sleep.

These findings raise the question of whether pain amplification can be dampened by preventing the inflammatory increase in response to insufficient sleep.

The primary goal of this pilot project is to gather preliminary support for the hypothesis that deficient sleep leads to pain amplification through an inflammatory mechanism.

In addition to the primary goal of this proposal, the secondary goal is to gather preliminary data on the effects of aspirin on blood pressure regulation. Cardiovascular disease is the leading cause of death in the United States. A modest reduction of blood pressure (BP; i.e., 3 to 5 mmHg) in the population will produce a significant fall in serious cardiovascular events (Turnbull, 2003). It has been reported that low-dose aspirin may significantly reduce BP (i.e., 6 to 7 mmHg) when taken at bedtime (Hermida et al., 1994;Hermida et al., 1997;Hermida et al., 2003b;Hermida et al., 2003a;Hermida et al., 2005a;Hermida et al., 2005b). Aspirin, when taken at bedtime, may modulate 24h blood pressure by decreasing the nocturnal rise of renin-angiotensin-aldosterone system (RAAS) activity (Snoep et al., 2009) and attenuating the nocturnal drop in nitric oxide (NO) production (Hermida et al., 2005b). However, the underlying mechanisms are still unknown. Therefore, the second goal of this pilot project is to investigate the potential mechanisms contributing to BP reduction in response to aspirin taken at bedtime.

What participants receive

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

  • AspirinDrug

    Also called non-steroidal anti-inflammatory drug

    81mg aspirin daily at bedtime over a 2 week period

  • PlaceboDrug

    pill that looks like aspirin without the effects of aspirin

What is being measured

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

  1. Inflammation

    interleukin 6

    Measured: Measured in plasma and urine 3 times/day over the 5-day in-hospital stay (after 2 weeks of pill admin)

Secondary outcomes (1)
  1. Pain sensitivity

    Thermode will be attached to the skin and participant has to rate the intensity of the heat or cold sensation via visual analog scales

    Measured: Measured once per day during in-hospital days 1-5 (after 2 weeks of pill admin)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Aspirin in people with Insomnia, run by Beth Israel Deaconess Medical Center at 1 site in United States.

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 6 inclusion and 9 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 15 Mar 2017. 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Inflammation (time frame: Measured in plasma and urine 3 times/day over the 5-day in-hospital stay (after 2 weeks of pill admin)). 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 15 Mar 2017.
