OBJECTIVE T-helper 1 (Th1) and Th17 lymphocytes are involved in experimental autoimmune encephalomyelitis, the model of multiple sclerosis (MS). We characterized the Th1/Th17 cell populations in peripheral blood (PB), their interferon (IFN) receptor expression sensitivity to IFN-beta in MS patients. METHODS In 30 untreated patients with active MS (AMS)(More)
BACKGROUND In RRMS, clinical exacerbations are usually associated with different types of active lesions at MRI, including: hyperintense lesions on T1-weighted post-gadolinium sequences; new hyperintense lesions or enlarging old lesions on PD/T2-weighted scans; or new hypointense lesions on T1-weighted pre-Gd sequences. OBJECTIVE/METHODS Primary outcome(More)
OBJECTIVE To prospectively validate MRI activity and neutralising anti-interferon antibody (NAb) during the first 6 months of interferon beta treatment as response indicators in multiple sclerosis (MS). METHODS Patients with relapsing-remitting MS were followed during the first 2 years of treatment. Neurological assessments were performed every 3 months(More)
Of 37 multiple sclerosis patients, 19 suboptimal responders were randomized to 375 (n=12) or 250µg (n=7) interferon (IFN)-β-1b. mRNA levels of 23 cytokines, chemokines, and chemokine receptors were quantified by TaqMan low-density array (TLDA) real-time polymerase chain reaction. Better treatment responses or increased IFN-β doses were associated with(More)
BACKGROUND Immunomodulatory drugs have been shown to be only modestly effective in clinically definite relapsing remitting multiple sclerosis (RRMS). It has been hypothesized that their efficacy could be higher if used at the first appearance of symptoms, that is in the clinically isolated syndromes (CIS) suggestive of demyelinating events, a pathology(More)
OBJECTIVE Recent findings support greater efficacy of early vs. delayed interferon beta (IFNbeta) treatment in patients with a first clinical event suggestive of multiple sclerosis (MS). We aimed to evaluate the effectiveness of early IFNbeta treatment in definite relapsing-remitting MS (RRMS) and to assess the optimal time to initiate IFNbeta treatment(More)
Long-term trials have demonstrated the continued efficacy of interferon (IFN) beta treatment in patients with relapsing-remitting (RR) multiple sclerosis (MS) during prolonged administration. The objective of the work was to evaluate the effects of reducing IFN beta administration frequency and total weekly dose in patients with RR MS who have achieved(More)
BACKGROUND Neutralizing antibodies (NAbs) to IFN-beta may have a detrimental effect on treatment response, but increasing IFN-beta dose could reduce their occurrence. The OPTimization of Interferon for MS (OPTIMS) study was a multicenter trial investigating clinical and MRI outcomes with the approved IFN-beta-1b dose (250 microg) and a higher dose (375(More)
IMPORTANCE The evaluation of therapeutic choices is needed after 24 doses of natalizumab in patients with multiple sclerosis (MS). OBJECTIVE To evaluate the effect of therapeutic choices on the mean annualized relapse rate and on magnetic resonance imaging MS activity after 24 doses of natalizumab in patients with relapsing-remitting MS. DESIGN,(More)
At present, two types of recombinant human interferon (IFN)-beta are in clinical use. IFN-beta1a is produced in genetically engineered Chinese hamster ovary cells, and its amino acid sequence and glycosylation pattern are identical to those of endogenous human IFN-beta. The beneficial effect of IFN-beta in multiple sclerosis (MS) probably results from(More)
