April 3, 2013 updated by: Manfred Weiss, University of Ulm

Phase 1 Study of Immune, Psychometric and Sociodemographic Patterns in Pain Patients Classified by DSM-IV

The purpose of this study is to define subgroups of patients with somatoform disorders due to DSM-IV by immunological, psychological and genetic characterization.

Detailed Description

Pain patients are defined as patients with a somatoform disorder due to DSM-IV, if chronic pain lasts for at least 6 months in several anatomical regions. Somatoform disorders (DSM-IV) have the presence of physical symptoms that suggest a general medical condition but that are not fully explained by a general medical condition, by the direct effects of a substance, or by another mental disorder. The symptoms must cause clinically significant distress or impairment in social, occupational, or other areas of functioning. The physical symptoms are not under voluntary control. Psychic factors exclusively or in combination with a medical disease factor influence onset, severity, exacerbation or maintenance of symptoms decisively. A subgroup of somatoform disorders, i.e., fibromyalgia, is a common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, headaches, and occasionally depression. There is significant overlap between fibromyalgia and the chronic fatigue syndrome. Fibromyalgia may arise as a primary or secondary disease process. Interleukins IL-1ß, IL-6 und tumor necrosis factor-a have been detected in the skin of these patients. Blockade of the 5HT3 receptor has been reported to alleviate chronic pain in tendopathy, fibromyalgia and autoimmune diseases. However, only a subgroup of patients responds to this therapy. It is supposed that patients with somatoform disorders (DSM-IV) diagnosed according to clinical criteria consist of immunologically heterogenous groups. However, up to now, the immunologic and genetic background of patients with somatoform disorders classified via DSM-IV has not been systematically evaluated. The study concentrates on the psychometric characterization of patients with pain disorder focusing on depression, anxiety, coping behavior, psychic trauma, alexithymia and somatoform symptoms. The present study is performed to define subgroups of patients with somatoform disorders (DSM-IV) by immunological, pyschologic and genetic characterization which may benefit from potential 5HT3 receptor antagonists or anti-inflammatory therapy.

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 90 years (Adult, Older Adult)

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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2007

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
