BACKGROUND:Multiple sclerosis is a debilitating autoimmune disorder that causes disability in young adults. OBJECTIVE:To review the efficacy and safety of IFN-beta1b in the management of relapsing-remitting and secondary progressive multiple scleroses and clinical isolated syndrome. METHODS:A MEDLINE (1966-May 2007) search of clinical trials using the terms 'multiple sclerosis' and 'interferon' was performed. Manual bibliographic search was conducted. English-language articles were evaluated. RESULTS:IFN-beta1b is more efficacious than placebo and at least as efficacious as IFN-beta1a or glatiramer for the management of relapsing-remitting multiple sclerosis. IFN-beta1b also delayed the time to diagnosis of definite multiple sclerosis and reduced brain lesion burden in patients with clinical isolated syndrome. More long-term, large scale clinical data are warranted to ascertain its relative efficacy compared to other treatments. CONCLUSION/CONCLUSIONS:IFN-beta1b is an effective treatment for multiple sclerosis. Common side effects are lymphopenia, injection site reactions, asthenia, flu-like symptoms and headache.

The objective of this study was to determine the clinical characteristics of multiple sclerosis (MS) in African American (AA) patients in the New York State Multiple Sclerosis Consortium (NYSMSC) patient registry. The NYSMSC is a group of 18 MS centers throughout New York State organized to prospectively assess clinical characteristics of MS patients. AAs comprise 6% (329) of the total NYSMSC registrants (5602). Demographics, disease course, therapy, and socioeconomic status were compared in AA registrants versus nonAfrican Americans (NAA). There was an increased female preponderance and a significantly younger age at diagnosis in the AA group. AA patients were more likely to have greater disability with increased disease duration. No differences were seen in types of MS and use of disease modifying therapies. Our findings suggest a racial influence in MS. Further genetic studies that consider race differences are warranted to elucidate mechanisms of disease susceptibility

We have obtained a current profile of multiple sclerosis York State through a centralized patient registry and standardized data collection instrument associated with the New York State Multiple Sclerosis Consortium of 12 MS centers located throughout the state. Data from the first 3019 patients with clinically definite MS revealed a clear relationship between MS disease type, duration of disease, and severity of physical disability. Patients with relapsing disease had disease durations approximately half as long as those with progressive forms of the disease (means approximately 6 years versus 11 years). The majority of patients with relapsing disease had Expanded Disability Status Scale (EDSS) scores of 4.0 or less (self-sustained, fully ambulatory), whereas the majority of patients with progressive disease types had EDSS scores of 6.0 or greater (at least unilateral assist for walking). These findings emphasize the importance of early intervention in patients with relapsing disease to slow or prevent the accumulation of physical disability associated with progressive types of disease. Progressive disease was associated with lack of full-time employment and being disabled before the age of 60 years. Patients with relapsing disease were more likely to be employed and have private forms of insurance, whereas patients with progressive types of disease were more likely to have government-supported insurance to cover medical expenses.
