Abstract
b
ackground: Multiple sclerosis (MS) is an inflammatory demyelinating disease of the
central nervous system affecting nearly 2 million people worldwide. The
pathogenesis of MS is at best incompletely understood. There are several proposed
mechanisms that may be important in the production of MS plaques: autoimmunity, infection,
bystander demyelination and heredity. Deviation of immune responses plays a central role in
the pathogenesis of MS. Auto antibodies to many myelin constituents is present in MS. These
antibodies may be an autoimmune reaction to an “MS antigens” or simply part of a
generalized “non-sense” antibody response. In either case, the antibodies may affect the
pathology of MS.
Objective: To study the association between Anti-myelin associated glycoprotein (anti
MAG) antibody and relapsing remitting multiple sclerosis in Iraq.
Method: 105 patients with relapsing remitting multiple sclerosis and 85 patients with other
neurological diseases (OND) as control group were recruited in this study. The cases were
collected from Baghdad teaching hospital, MS center, Baghdad, Iraq at the period from April
2009 to February 2010. The sera of all patents were tested for MAG- antibodies.
Results: The present study showed increase in the percent of patients with positive anti
MAG antibody in patients with relapsing remitting multiple sclerosis than the control group
(7.6% in the patients group viz 3.5% in the control group) but with no statistical significance.
Also among patients group we try to study the relationship between severity of the disease
measured by expanded disability status scale (EDSS) and positive serum anti-MAG antibody
and we found no significant statistical association.
Conclusion: There is a higher percent of patients with positive anti-MAG antibody in the
serum of patients with relapsing remitting multiple sclerosis than the control group
