Trial summary

A series of studies in patients with major depression have consistently demonstrated a doubling of the mortality rate at any age, independent of suicide.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Adults between the ages of 21 and 55, with or without major depression as diagnosed with The Structured Clinical Interview of Diagnosis (SCID) of the Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-IV), will be recruited. All depressed patients will be included, although we will characterize patients a priori as having a predominantly melancholic, atypical, or mixed symptom pattern. We plan to recruit at least 20 patients in each group.
  • Both currently depressed patients (greater than 14 on the Hamilton Depression Rating Scale) and those with a history of major depression who are clinically recovered will be included. Patients may be taking psychotropic medications for depression at the time of study. Sub-analyses will be done comparing steady-state glucose utilization rates as a function of mood state and medication status. Subjects should not have significant underlying illnesses known to affect insulin sensitivity, and should have a body mass index between 20 and 30 kg/m2.

Who cannot join

  • Pregnancy
  • Existing diabetes mellitus
  • Body mass index less than 20 or greater than 30 kg/ m2
  • Existing cardiovascular diseases and other end organ diseases
  • Existing peripheral vascular disease
  • HIV infection
  • Patients who are on B-blockers, thiazides, and/or glucocorticoids and cannot discontinue these medications.
  • Subjects who are on oral contraceptives need to discontinue the medication for 1-2 days before the clamp study.

About this study

Official title: Factors in Susceptibility to Ischemic Heart Disease in Major Depression: Documentation of Insulin Resistance in Patients With Major Depression Utilizing the Hyperinsulinemic Euglycemic Glucose Clamp

A series of studies in patients with major depression have consistently demonstrated a doubling of the mortality rate at any age, independent of suicide. In addition, the relative risk for clinically significant coronary artery disease in patients with major depression is also 2 or more in studies that independently controlled for risk factors such as smoking, hypertension, etc. The principal long-term goals of the CNE include the determination of the mechanisms that underlie enhanced susceptibility to premature ischemic heart disease in patients with major depression, documenting the age at which demonstrable pathophysiologic or predictive changes begin to occur, and charting their rate of progression. Our long-term goal is to use our understanding of underlying mechanisms to enhance our capacity to predict who with major depression is most likely to develop premature ischemic heart disease, to determine what the mechanisms underlying this susceptibility are, and to develop improved means for treatment and prevention.

Depressed patients are known to manifest a variety of neuroendocrine changes that predispose to coronary artery disease including hypercortisolism, decreased secretion of growth hormone and a deficiency of sex steroids. A final common denominator of these neuroendocrine abnormalities is insulin resistance. Insulin resistance promotes several changes that would favor hypertension and increased coronary artery disease including increased sodium retention, increased activity of the sympathetic nervous system, proliferation of vascular smooth muscle and deposition of highly metabolically active visceral fat. The latter induces additional risk factors for coronary disease, including dyslipidemia, hypercoagulation, and enhanced inflammation. It is a matter of public health importance to document the frequency and severity of insulin resistance in patients with major depression compared to a closely matched group of healthy controls. To accurately quantify insulin resistance in each patient and control, we will apply the hyperinsulinemic euglycemic glucose clamp procedure. This is the gold standard method for measuring the insulin sensitivity since it reflects the direct human body glucose metabolic response to a known insulin infusion. Moreover, it is essential to use this technique in patients with major depression as data indicate that other alternative procedures give unreliable results in the context of hypercortisolism.

Questions about this trial

What is this clinical trial studying?

An observational study of Adrenal Gland Hyperfunction and Cardiovascular Disease, run by National Institute of Mental Health (NIMH) 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 2 inclusion and 8 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 2 Jul 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. 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?

On the ClinicalTrials.gov record for NCT00001969, which also lists 1 linked publication.

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 2 Jul 2017.
