Brief Summary:
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.

Condition or disease
Multiple Sclerosis

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

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
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
