Purpose

To investigate whether genotypic differences can be identified between MS patients developing 'liver injury' (defined as ALT levels five times the upper normal limit and above) compared to those not developing liver injury after exposure to beta-interferon for MS.

Primary Outcome Measures:

Experienced an adverse drug reaction or not? [ Time Frame: No specified time frame ] [ Designated as safety issue: Yes ]

Biospecimen Retention: Samples With DNA

Saliva


Estimated Enrollment:	300
Study Start Date:	June 2010
Estimated Study Completion Date:	December 2015
Estimated Primary Completion Date:	December 2015 (Final data collection date for primary outcome measure)

Groups/Cohorts
Case MS patients experiencing an adverse drug reaction to an MS immunomodulatory therapy
Control MS patients not experiencing an adverse drug reaction to an MS immunomodulatory therapy

Detailed Description:

PURPOSE: To investigate whether genotypic differences can be identified between MS patients who develop liver injury compared to those who do not develop injury in response to beta-interferon therapy.

OBJECTIVE: To determine whether elevated liver enzyme tests (ALT > 5 times the upper limit of normal) in response to beta-interferon therapy in MS patients is associated with genetic polymorphisms.

METHOD OF RECRUITMENT:

Patients will be identified through a clinic database and chart reviews. An introductory letter will be mailed to potential participants, inviting them to volunteer. A follow-up phone call will be made to determine interest and consent into study.

PROCEDURES:

Saliva will be collected for genetic analyses and a questionnaire will be administered

Eligibility


Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No
Sampling Method:	Non-Probability Sample

Study Population

Multiple sclerosis (MS) patients attending MS clinics located at the University of British Columbia Hospital, Winnipeg Health Sciences Centre, Dalhousie (Halifax, Nova Scotia) MS clinic, London Health Sciences Centre (London, ON) and Hôpital Notre-Dame (Montréal). Participants must have definite MS (Poser or McDonald criteria), with a relapsing-remitting or secondary-progressive disease course, registered at one of the above MS Clinics and prescribed a beta-interferon as an immunomodulatory drug for MS.

Criteria

Inclusion Criteria: Cases and controls must have

definite MS (Poser or McDonald criteria)
relapsing-remitting or secondary-progressive disease course
Prescribed a beta-interferon as their immunomodulatory drug for MS

Exclusion Criteria:

primary-progressive MS
an elevated liver test result within 6 months of starting beta-interferon treatment
presence of a co-morbidity that is a known risk-factor for liver injury
