Quality Assessment in Multiple Sclerosis Therapy (QUASIMS): a comparison of interferon beta therapies for relapsing-remitting multiple sclerosis.

Interferon beta (IFN beta) preparations are the most frequently prescribed therapies for patients with relapsing multiple sclerosis (MS). Several open-label observational studies report similar efficacy among IFN beta preparations. The Quality Assessment in Multiple Sclerosis Therapy (QUASIMS) study is a large, open-label observational study designed to compare the effectiveness and tolerability of available IFN beta preparations as disease-modifying therapies for relapsing MS across a wide range of clinical practice settings. This retrospective, controlled cohort study was conducted by chart review at 510 sites in Germany, Austria, and Switzerland. Enrolled patients had received one of the four available IFN beta preparations/dosing regimens (intramuscular IFN beta-1a 30 microg 1x/week [Avonex], subcutaneous (SC) IFN beta-1a 22 or 44 microg 3 x/week [Rebif], or SC IFN beta-1b 250 microg 3.5x/week [Betaferon/Betaseron]) for >or= 2 years. Pre-planned outcomes at 1 and 2 years included change from baseline Expanded Disability Status Scale (EDSS) score, percentage of progression-free patients (< 1.0 EDSS point), annualised relapse rate (RR), percentage of relapse-free patients, and reasons for therapy change. Of 4754 evaluable patients, 3991 (84%) received IFN beta as initial therapy. There were no significant differences among IFN betas when used as initial or follow-up therapy on almost all outcome variables. Relapse rate was consistently higher and percentage of relapse-free patients consistently lower for all products used as follow-up versus initial therapy. Results of QUASIMS showed similar effectiveness among IFN beta products. Benefits were consistently superior when IFN beta was used as initial rather than follow-up therapy. Our results suggest that patients do not benefit in terms of disease outcome from switching between IFN beta preparations/dosing regimens.

Symptomatology of MS: results from the German MS Registry.

Since 2002, an MS Registry has been implemented by the German MS Society in more than 100 German MS centres. The objective is to provide information about disease characteristics, and to monitor the health care situation in a large population of patients. The aim of this report is to give detailed results on MS symptoms. By October 2008, data sets from 16,554 patients were recorded by 86 centres. A strikingly high number of persons suffered from fatigue and other "invisible" symptoms during early and late stages of the disease, underscoring the negative impact of these symptoms on quality of life in MS patients.

Multiple sclerosis registry in Germany: results of the extension phase 2005/2006.

INTRODUCTION: In 2001, a nationwide multiple sclerosis (MS) registry was initiated in Germany under the auspices of the German MS Society, (DMSG Bundesverband e.V.). The project aimed at collecting epidemiological data and information on health care provision for MS patients in Germany. METHODS: After a 2-year pilot phase, the original entry mask was modified, and new centers were recruited, resulting in the registration of a total of 5821 patients in 2005 and 2006. Following a 2 stage quality control process, standardized data sets for 5445 patients (93.5%) were able to be analyzed. RESULTS: Mean duration from onset of disease to diagnosis was 3.5 years. More than 70% of patients received immunomodulatory drugs, whereas symptomatic treatments were less commonly administered. The number of participating centers as of 31 December 2006 was 57 (29 neurological hospitals, 11 rehabilitation units, 13 specialized practitioners, and 4 regional MS centers). DISCUSSION: The MS registry provides valuable data on patterns of care for MS patients in Germany, and may help to improve service provision and overall quality of life for these patients.
