Sleep and Healthy Aging Research for Depression (SHARE-D) Study

About

Brief Summary

Late-life depression is a significant public health concern, and effective interventions for prevention and treatment are needed. Insomnia and inflammation are modifiable targets for depression prevention, and this study is significant in using an experimental approach (i.e., inflammatory challenge) to probe acute inflammatory- and depression responses as a function of insomnia, which will inform identification of molecular targets for pharmacologic interventions, and improvement of insomnia treatments to prevent depression in older adults.

  • Inclusion Criteria: - Participants will be required to be in good general health (as evaluated during the phone and in-person baseline session) - Participants will be aged 60 to 80 years. - Half the participants (N=80) will be those with insomnia disorder as assessed by the Structured Clinical Interview for Diagnosis, Diagnostic Statistical Manual 5 and the Duke Structured Interview for Sleep Disorders, and will be required to fulfill a minimal severity of mild insomnia with a Insomnia Severity Index score greater than 10, as well as evidence of poor sleep efficiency (<85%). - The other half will be those without insomnia identified as not having insomnia by any of these assessments.
  • Exclusion Criteria: Following a structured telephone interview, prospective participants with the following conditions will not advance to the in-person baseline session:
    • Presence of chronic mental or physical illness (except for insomnia)
    • History of allergies, autoimmune, liver, or other severe chronic diseases,
    • Current and regular use of prescription medications such as steroids, non-steroid anti-inflammatory drugs, aspirin, immune modifying drugs, opioid analgesics, statins, antihypertensive drugs, anti-arrhythmic drugs, and antidepressant medications (none in the last 6 months); and nightshift work or time zone shifts (> 3hrs) within the previous 6 weeks, or previous history of fainting during blood draws.
    • Presence of co-morbid medical conditions not limited to but including cardiovascular (e.g., history of acute coronary event, stroke) and neurological diseases (e.g., Parkinson's disease), as well as pain disorders;
    • Presence of comorbid inflammatory disorders such as rheumatoid arthritis or other autoimmune disorders;
    • Presence of an uncontrolled medical condition that is deemed by the investigators to interfere with the proposed study procedures, or to put the study participant at undue risk;
    • Presence of chronic infection, which may elevate proinflammatory cytokines;
    • Presence of an acute infectious illness in the two weeks prior to an experimental session.
    • Current Axis I psychiatric disorders as determined by the Research Version of the Structured Clinical Interview including a current major depressive disorder and substance dependence (a prior history of depression is not an exclusion criterion, which will be considered for a pre-planned sensitivity analysis and will be used as a pre-classification variable in the generation of the two groups, and in the randomization schedule);
    • Lifetime history of suicide attempt or inpatient psychiatric admission. Sleep Disorders:
    • Current history of sleep apnea or nocturnal myoclonus;
    • Phase-shift disorder, which will be identified by the Structured Clinical Interview and the Duke Structured Interview for Sleep Disorders ; Medication and Substance Use:
    • Current and/or past regular use of hormone-containing medications including steroids;
    • Current and/or past regular use of non-steroid anti-inflammatory drugs;
    • Current and/or past regular use of immune modifying drugs that target specific immune responses such as cytokine antagonists;
    • Current and/or past regular use of analgesics such as opioids;
    • Current and/or past regular use of cardiovascular medications, including antihypertensive, antiarrhythmic, antianginal, and anticoagulant drugs;
    • Use of antidepressant medications or other psychotropic medications; (16) current smoking or excessive caffeine use (>600 mg/day) because of the known effects on proinflammatory cytokine levels;
    • Evidence of recreational drug use from urine test. Health Factors:
    • Body mass index > 35 because of the effects of obesity on proinflammatory cytokine activity and also on risk for sleep disordered breathing;
    • Any clinically significant abnormality on screening laboratory tests
    • Clinically significant abnormalities in electrocardiogram
