Trial summary

This is a pilot study. We are testing the physiologic, immune and chemical responses to stress. We believe the results of all measures to stress will be blunted in schizophrenia compared to healthy controls. We will test sex, early life stress and other factors on the relationship to a stress response. Read more about this study

About this study

This is a pilot study. We are testing the physiologic, immune and chemical responses to stress. We believe the results of all measures to stress will be blunted in schizophrenia compared to healthy controls. We will test sex, early life stress and other factors on the relationship to a stress response.

Read the detailed description

The proposed study examines the response of neuroimmune and inflammatory responses to a stress in both men and women with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder. The measurements include stress hormones or other elements in the blood which indicate stress . Early childhood trauma/stress (ELS) information will be collected so we can examine differences in those with trauma histories vs. those with none by sex. There will be one visit for screening before the testing visit. The sample will consist of up to 45 clinically stable inpatients and outpatients with DSM-IV schizophrenia or schizoaffective disorder, of which approximately 15 will be women. We will also enroll up to 45 healthy controls without a DSM-IV Axis I or II disorder. Prior to the study all subjects must meet inclusion and exclusion criteria including a medical history.

The (TSST) is a standard and widely used research assessment procedure that is used to reliably induce stress in human research participants. The TSST uses situations where people think they are being socially evaluated during an interview for a job. Participants are told they are competing with other people for this job, and their task is to convince interviewers that they are the best person for the job. Participants are told they have to prepare a speech, and complete a math challenge in their head.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Trier Social Stress TestBehavioural

    Participants will participate in a standardized role play (Trier Social Stress Test ). A role play is pretending to be in a certain situation. A research staff member will describe the role play, during which teh participant will act out a scene. Participants will be asked to imagine that they are in a certain role with several other research team members who will also participate in the role play. Participants will also be asked to do some math problems without using paper or pencil.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Aim 1) To examine neuroendocrine and physiologic response following a psychosocial stressor in people with schizophrenia and healthy controls.

    We will administer the Trier Social Stress Test (TSST) and measure neuroendocrine values (plasma and salivary cortisol and adrenocorticotropic hormone (ACTH) and physiologic variables (heart rate, blood pressure) before during and after the TSST.

    Measured: 1 week

Secondary outcomes (1)
  1. To investigate neuroimmune and kynurenic acid modulation to a psychosocial stressor in people with schizophrenia and healthy controls

    We will measure peripheral cytokine response (IL-6, IL1-Beta, TNF alpha) and kynruenic acid, kynurenine and pathway metabolites before, during and after the TSST.

    Measured: 1 week
