Enhancing Psychotherapy for Mood Disorders With Whole Body Hyperthermia
Study Overview
Status
Conditions
Detailed Description
Our research group has observed in an open trial that a single session of whole body hyperthermia (WBH) induced rapid antidepressant effects that persisted for at least a week in patients with major depression (MDD) severe enough to warrant inpatient hospitalization. In addition to reducing depression, the single session of WBH induced a prolonged reduction in mean core body temperature, consistent with basic science data from our group suggesting that hyperthermia activates a skin-to-brain pathway that targets specific serotonergic nuclei in the raphe. In animal models, these nuclei have been shown to be important for mood and body temperature regulation. Consistent with this known anatomy in our preliminary study in depressed patients, reductions in core body temperature were highly correlated with reductions in depressive symptoms over the same time period (one week post WBH). Moreover, patients with higher mean core body temperature prior to treatment had enhanced antidepressant effects. Because increased body temperature is an outcome of poor functioning in the skin-to-brain pathway activated by WBH our data suggests that WBH may actually sensitize this pathway in ways that promote changes in brain functioning known to promote emotional well-being. The results of our first open trial have encouraged us to conduct a larger, more rigorous placebo-controlled, double blind study of WBH for MDD, which is currently underway at the University of Arizona Medical School.
In addition to impacting depressive symptoms and body temperature, The investigators have observed that WBH induces striking increases in prosocial and self-disclosing behavior in many individuals. This effect initiates in the heating phase of the treatment and culminates at maximum body temperature. Importantly, our observations thus far suggest that this prosociality only occurs when the person in the hyperthermia box is accompanied by someone he/she knows to at least some degree. For example, a recent subject was silent during his initial WBH treatment in which he was attended by one of our staff that he had never met. He elected to get a repeat WBH session. The same "attendant" was present for this second WBH session, and during this session the patient became strikingly talkative and without prompting self-disclosed a range of very intimate personal issues related to his depression, such as a previously undisclosed history of childhood sexual abuse.
The goal of the current proposal is to conduct a pilot study to evaluate whether this observed prosocial effect of WBH might be employed to accelerate and deepen the formation of therapeutic alliance in patients undergoing an 8-12 session course of cognitive behavioral psychotherapy (CBT). Our study design will also more rigorously test our clinical observation about the prosocial effects of WBH. In addition to potentially enhancing psychotherapeutic outcomes, the current study may provide data relevant to larger issues related to the near universal use of hyperthermia in indigenous cultures around the world for spiritual and health purposes.

- A diagnosis claustrophobia severe enough that it would impair ability to be in the Heckel HT3000 hyperthermia device
- A current (or within 12 months prior to the Screening visit) diagnosis of Anorexia Nervosa or Bulimia Nervosa
- Subject has a medical condition or disorder that:
- Is unstable and clinically significant, or:
- Could interfere with the accurate assessment of safety or efficacy of treatment, including:
- individuals who are using prescription drugs that may impair thermoregulatory cooling, including diuretics, barbiturates, and beta-blockers, or antihistamines,
- individuals with cardiovascular conditions or problems (uncontrolled hypertension, congestive heart failure, or documented evidence of coronary artery disease)

- Current participation in any clinical trial that might impact results of this one, which includes participation in another clinical trial for depression, as well as drug trials with agents that might affect mood or regulation of body temperature.
- Reasonable likelihood for non-compliance with the protocol for any other reason, in the opinion of the Investigator, prohibits enrollment of subject into the study.
- Obesity and overall size of subject. It will be up to the PI's discretion will consider BMI, waist circumference, and body fat composition when determining eligibility and safety of the individual.

- History of a cerebral vascular accident
- History of stroke, epilepsy or cerebral aneurisms
- Cancer in the last five years.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Psychotherapy and Questionnaire Group
Participants in this arm will have their regular psychotherapy sessions with their psychotherapist and will, prior to each session, fill out study related questionnaires.
|
Weekly psychotherapy using cognitive behavioral therapy sessions with a therapist.
Weekly questionnaires to assess changes in mood, perceptions of self and perceptions of effectiveness of the therapist/patient bond will be administered.
|
Experimental: High intensity whole-body infrared heating and Psychotherapy.
Subjects will have weekly psychotherapy sessions and fill out study questionnaires.
The participant's 4th psychotherapy session will be conducted while the patient undergoes the WBH intervention where subjects will be induced to levels of heat that increases core body temperature to approximately 37.5-38.5 °C.temperature.
|
Weekly psychotherapy using cognitive behavioral therapy sessions with a therapist.
Weekly questionnaires to assess changes in mood, perceptions of self and perceptions of effectiveness of the therapist/patient bond will be administered.
The Whole Body Hyperthermia system uses water-filtered infrared-A (wIRA) heat radiation.
The rise in the body's core temperature is correspondingly rapid and well-tolerated.
There are two phases of the thermal challenge, 1) Irradiation phase during which the patient lies recumbent with his/her head positioned outside the tent.
The wIRA irradiators are arranged above the exposed upper part of the body; and 2) Heat retention phase during which the patient lies in the chamber with the walls of the tent positioned to retain heat.
Core body temperatures will be raised to those comparable to a mild fever 37.8-38.5°C.
|
Sham Comparator: Low intensity whole-body infrared heating and Psychotherapy
Subjects will have weekly psychotherapy sessions and fill out study questionnaires.
The participant's 4th psychotherapy session will be conducted while the patient undergoes WBH-control where subjects will be induced to levels of heat that causes only a minor increase in body temperature.
|
Weekly psychotherapy using cognitive behavioral therapy sessions with a therapist.
Weekly questionnaires to assess changes in mood, perceptions of self and perceptions of effectiveness of the therapist/patient bond will be administered.
Attenuated heating using only heating coils at the bottom of the Heckel device.
This results in only a minor increase in skin temperature and no increase in core body temperature.
The participant will still feel heat and will see similar lighting and hear similar sounds as those occurring during actual WBH, and will be in the chamber for the same period of time.
