AB It is widely believed that multiple sclerosis is a T-cell mediated
autoimmune disease associated with abnormalities in immunoregulation.
This large, prospective study evaluated the lymphocyte immunophenotypic
profile of 246 MS patients, divided clinically into a
remitting/relapsing group (n = 176) and a progressive group (n = 70),
and compared their results to those of 117 healthy controls. All
patients were found to have significantly elevated percentage and
absolute numbers of IL2R+CD3+ cells as well as depressed percentages of
CD45RA+CD4+ cells. However, when the factor of treatment with
cyclophosphamide (CY) versus no treatment or treatment with other agents
was used to group patients, dramatic declines in both percentages and
absolute numbers of CD45RA+CD4+ cells were discovered. These declines
were associated specifically with CY and and could be explained by this
factor independent of the clinical state of the patient. The effects
were seen in patients undergoing current treatment or in those exposed
to CY in the near or remote past. These findings highlight the
confounding effect of specific treatments on the immune profile of MS
patients groups and suggest that there may be important implications for
cellular function and clinical outcome in these and other patient
groups.
