BACKGROUND Interferon beta reduces activity in multiple sclerosis as measured clinically and by magnetic resonance imaging (MRI). We assessed the effect of interferon beta-1a on the occurrence of relapses in patients after first presentation with neurological events, who are at high risk of conversion to clinically definite multiple sclerosis. METHODS(More)
Several but not all studies have provided evidence for the association between multiple sclerosis (MS) and the T244I variant of the interleukin-7 receptor-alpha gene (IL7RA), rs6897932. We performed a new replication case-control study in 599 MS patients and 594 healthy controls, all Caucasians from the south of Spain. The genotype and allele frequencies(More)
In the recently proposed diagnostic criteria for multiple sclerosis (MS) by McDonald, the modified magnetic resonance imaging (MRI) Barkhof criteria have been incorporated. We examined the validity of this implementation in the Early Treatment of MS study, a randomized, double-blind, placebo-controlled study of 22 microg interferon beta1a given(More)
This study aims to validate the Multiple Sclerosis (MS) International Quality of Life (MusiQoL) questionnaire, a multi-dimensional, self-administered questionnaire, available in 14 languages, as a disease-specific quality of life scale that can be applied internationally. A total of 1992 patients with different types and severities of MS from 15 countries(More)
T HE PRESEXCE Of a malabsorption syndrome in patients with cirrhosis has long been suspected. There are several theoretical mechanisms which could account for faulty absorption of metabolites in these patients. One cause could be the malnutr i t ion frequently present in cirrhotics. The re is evidence that a deficiency in proteins and phost)holipids may(More)
Multiple Sclerosis (MS) is the most common progressive and disabling neurological condition affecting young adults in the world today. From a genetic point of view, MS is a complex disorder resulting from the combination of genetic and non-genetic factors. We aimed to identify previously unidentified loci conducting a new GWAS of Multiple Sclerosis (MS) in(More)
The -330 IL2 gene promoter polymorphism has been associated with multiple sclerosis (MS) [J. Neuroimmunol. 119 (2001) 101], but the basis underlying this association remains unknown to date. In the present work, we have found that IL2 promoter-luciferase constructs, transfected in Jurkat cell line, showed twofold higher levels of gene expression in the -330(More)
OBJECTIVE To identify promising candidate genes linked to interindividual differences in the efficacy of interferon beta therapy. Recombinant interferon beta therapy is widely used to reduce disease activity in multiple sclerosis (MS). However, up to 50% of patients continue to have relapses and worsening disability despite therapy. DESIGN We used a(More)
BACKGROUND Little is known about how the level of disability at the start of treatment with natalizumab affects its efficacy. OBJECTIVES The aim of this study was to investigate the effect of natalizumab on relapses in patients with different levels of baseline disability associated with MS. METHODS This single-centre observational study collected(More)
