Evaluation of Coagulation in Multiple Sclerosis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01711255
Recruitment Status : Completed
First Posted : October 22, 2012
Last Update Posted : July 28, 2017

Bastyr University

Brief Summary:
Recent research in multiple sclerosis (MS) have suggested that altered coagulation and vascular inflammation may play a role in pathophysiology of MS. Sonoclot is viscoelastic method of analyzing clot formation. This instrument will be used to compare coagulation in individuals with MS to healthy controls. A 24-hour dietary recall and food frequency questionnaire will help determine whether coagulation is modified by fish consumption.

Condition or disease
Multiple Sclerosis

Detailed Description:
This case-control study will recruit individuals with a diagnosis of MS and healthy controls. Individuals will be asked to come to Bastyr Clinical Research Center for a single study visit, at which time dietary intake, current medications and supplements, other medical diagnoses, and coagulation will be evaluated.

Multiple Sclerosis
Subjects who have been diagnosed with clinically definite or probable multiple sclerosis as defined and recorded by board certified neurologist.
Healthy controls
Adults age 18 and older who have not been diagnosed with any neurological, endocrine, or other chronic health condition. They must also be free of any recent acute illness that can impact inflammation/clotting.

Primary Outcome Measures :
  1. Sonoclot Coagulation Spectrum (Sonoclot Signature) [ Time Frame: Day 1 ]
    The Sonoclot Coagulation Spectrum represents a combination of coagulation parameters, including activated clotting time, clot rate, time to peak, and peak amplitude. The mean value of all contributing parameters will be compared between cases and controls.

Secondary Outcome Measures :
  1. ASA24 omega-3 fatty acid intake [ Time Frame: 24 hour recall (24 hours prior to study visit) ]
    The ASA24, in combination with a medication history, will be used to evaluate whether omega-3 fatty acid intake is associated with reduced rates of coagulation in either cases or controls.

Biospecimen Retention:   Samples With DNA
Six (6) whole blood vials of 10ml each will be collected from each subject. Three (3) will be stored for future use. Three will be used immediately for coagulation analysis using Sonoclot.
