August 15, 2016 updated by: NYU Langone Health
The purpose of this study is to use positron emission tomography (PET) imaging and magnetic resonance imaging (MRI) to understand the brain function of individuals with anorexia nervosa and healthy controls.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a 3-year study involving n=7 women with anorexia nervosa - recovered (AN-REC) from restricting subtype that have achieved a body mass index (BMI) > 18.5 in the past year, are medication free, range in age from 18-55 years and n=7 healthy (medical and psychiatric statues) age- and weight-matched controls who are invited to participate in a medical and psychiatric evaluation, neuroendocrine assessments, one magnetic resonance imaging (MRI) study and one positron emission tomography (PET) study kappa opioid receptor (KOR) 11-carbon (11C) [11C]PKAB and PET. Subjects will be asked to provide written informed consent after full explanation of all study procedures and risks and benefits related to study participation. On the screening day a full medical evaluation including blood work, urine analyses, toxicology, electrocardiogram (ECG) and physical exam will be performed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Subjects are female, between the age range of 18 to 55, are medically healthy and currently not taking any medications to treat any medical illness, and have a history of anorexia nervosa and are recovered or never had a history of anorexia nervosa.

Description

Inclusion criteria for anorexic patients:

  1. Able to understand the consent form document
  2. A willingness to participate in a psychiatric evaluation, collection of behavioral ratings and neuroendocrine assessments, and imaging studies including 1 PET scan and 1 MRI scan
  3. Meets criteria for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Anorexia Nervosa (AN)
  4. Subjects will be between 18 and 55 years of age
  5. Currently weight restored with a body mass index (BMI) > 18.5 for longer than 3 months

Inclusion criteria for healthy controls:

  1. Able to understand the consent form document
  2. A willingness to participate in a psychiatric evaluation, collection of behavioral ratings and neuroendocrine assessments, and imaging studies including 1 PET scan and 1 MRI scan
  3. Subjects will be between 18 and 55 years of age
  4. Regular menstruation and no personal or first-degree family history of any Axis I diagnosis based on DSM-IV criteria

Exclusion criteria for anorexic patients:

  1. Any major neurological illness or injury
  2. Presence of any legal or illegal psychoactive substances determined with urine toxicology, and breathalyzer test for alcohol

  4. Intelligence quotient (IQ)<70 based on past intelligence
  5. Any metal in body that would pose a risk with MRI
  6. Claustrophobia that would interfere with MRI or PET imaging
  7. Currently pregnant or nursing

Exclusion criteria for healthy controls:

  1. Any major neurological illness or injury
  2. Presence of any legal or illegal psychoactive substances determined with urine toxicology, and breathalyzer test for alcohol
  3. Any significant unstable medical condition such as asthma or heart disease which may limit the interpretation of the imaging results, for example due to changes in tracer delivery in hypertensive patients
  4. IQ<70 based on past intelligence
  5. Any metal in body that would pose a risk with MRI
  6. Claustrophobia that would interfere with MRI or PET imaging

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Volume of distribution (VT) (i.e., KOR binding) using [11C]PKAB and PET imaging
Time Frame: Two months
In this study we are using the KOR radioligand [11C]PKAB and PET to investigate group differences in cerebral KOR binding potential in 7 AN-REC and 7 healthy controls (HCs).

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
