Investigation of the Effects of Sleep Deprivation on Itch & Pain

Status Recruiting

Clinical Trial Summary

In This experiment, the investigators would like to test following hypotheses regarding the influence of sleep deprivation on itch: - To investigate similarity and differences between itch and pain by comparing the effect of sleep deprivation in them. - To evaluate the inflammatory state induced by sleep fragmentation via the analysis of C-reactive protein (CRP) levels from blood samples. - To correlate the anxiety and depression scores (evaluated through questionnaires) with itch and pain sensitivity and evaluate how they are affected by sleep.

Clinical Trial Description

Chronic itch affects approximately a fifth of the global population and is associated with substantial negative consequences for the affected individuals. Furthermore, there is a lack of efficient treatment options for chronic itch. Poor sleep is a common companion of itch and is often reported by patients with chronic itch. Poor sleep is often characterized by nightly awakenings and troubles falling asleep. This is a significant problem as poor sleep in general is associated with lowered quality of life. While previous research has already established the negative impact of itch on sleep, it is yet to be studied whether the opposite tendency might be true as well. Knowledge about patients with chronic pain has shown that poor sleep can increase the sensitivity to pain and inflammation, and this tendency can also be observed in healthy participants after experimental sleep provocations. Therefore, the investigators wish to investigate how sleep provocations affect markers of itch in healthy participants. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
