简要总结
Randomized control trial assessing supplemental melatonin for youth with at-risk or psychotic symptoms.
详细描述
Context: Sleep disturbances and circadian dysrhythmias have been associated with psychotic symptom severity in Psychosis Spectrum (PS) youths. Supplemental melatonin is a safe over-the-counter dietary supplement, and several studies have found that melatonin improves sleep across several childhood neuropsychiatric disorders.
Objectives: Investigators seeks to determine whether supplemental melatonin improves sleep and circadian alignment in PS youth. Investigators will also investigate whether supplemental melatonin affects psychotic symptoms, neurocognition, and peripheral inflammatory and oxidative stress markers.
Study Design: Parallel group, double-blind, randomized, placebo-controlled trial Setting/Participants: 40 PS youths ages 11-30 years old (throughout the protocol we use "youth" to describe this age group) with sleep disturbances will be recruited from an extant cohort of PS youths followed by our lab in the Philadelphia Neurodevelopmental Cohort (PNC), Children's Hospital of Philadelphia (CHOP), University of Pennsylvania (UPenn), and the surrounding community. The study will be conducted at CHOP and UPenn.
Study Interventions and Measures: Youths will be randomized to receive pill placebo or oral melatonin. Participants will take melatonin (or placebo) at the same time every evening for 2 weeks (final dose range 2.5-10 mg nightly). Outcomes will be assessed at 1 week, 2 weeks, and 6-months. Primary outcomes will be changes in self-reported sleep and actigraph-measured sleep and circadian rhythm. Secondary outcomes will be psychotic symptoms, neurocognition, and peripheral blood markers of inflammation and oxidative stress.

研究组 & 干预措施
Placebo
Subjects will receive pill placebo nightly
干预措施: Placebo (Other)
Melatonin
Subjects will receive oral melatonin tablets 2.5-10mg nightly for 2 weeks. All will receive melatonin 5mg for one week, then at the 1 week visit, the dose can be continued at 5mg or adjusted to 2.5mg or 10mg nightly based on clinical assessment of patient response and side effects.
干预措施: oral melatonin tablets (NatureMade brand) (Drug)
结局指标
主要结局
Actigraph-measured sleep (increased total sleep time)
时间窗: Change in total sleep time from melatonin randomization day (Day 0) to Day 14
Actigraph-measured total sleep time will be used to assess actigraph-measured sleep efficacy, Actigraphs from the Actigraph Company will be used to analyze the data using Actilife software.
次要结局
- Improved self-reported sleep(Change in total PSQI from melatonin randomization day (Day 0) to Day 14)
