Quality of life and life circumstances in German myasthenia gravis patients

<p>Abstract</p> <p>Background</p> <p>Myasthenia gravis (MG) is a chronic neuromuscular disease. Advances in medical therapy have continuously increased the life expectancy of MG patients, without definitively curing the disease. To analyze life circumstances and quality of life (QoL), a large German MG cohort was investigated.</p> <p>Methods and Sample</p> <p>In cooperation with the German Myasthenia Association, 2,150 patients with confirmed MG were asked to respond to a mailed questionnaire. The standardized questions related to demographic data, impairments, therapeutic course, use of complementary therapies, illness-related costs, and quality of life (SF-36). In total, 1,518 patients participated, yielding a response rate of 70.6%. The average age was 56.7 years, and the proportion of females 58.6%.</p> <p>Results</p> <p>Despite receiving recommended therapy, many patients still suffered from MG-related impairments. In particular, mobility and mental well-being were reduced; moreover, quality of life was markedly reduced. Stepwise linear regression analysis revealed illness stability, impairments, mental conditions, comorbid diseases, and employment to be determinants of QoL.</p> <p>Conclusion</p> <p>Results indicate that despite prolonged life expectancy among MG patients, health-related quality of life is low. This outcome resulted mainly from impaired mobility and depression. Physical and mental well-being might be improved by additional therapy options. Additionally, health care resources could be used more efficiently in these patients.</p

REBISTART: Adherence of Patients with Multiple Sclerosis to Treatment with Subcutaneous Interferon Beta in the Context of a Patient Support Program.

INTRODUCTION Treatment adherence is a critical success factor in the disease-modifying therapy (DMT) of multiple sclerosis (MS). The REBISTART study prospectively evaluated adherence in patients using components of a patient support program (PSP). METHODS The 12-month non-interventional multicenter study examined the real-world adherence to subcutaneously (sc) injected interferon beta-1a (Rebif®). Patient-assessed adherence was measured by a visual analog scale (VAS) and the Morisky Medication Adherence Scale (MMAS). Objective adherence data were obtained by readouts from the RebiSmart® injection device. RESULTS Of 333 patients, 70.9% used the nursing service as the core component of the PSP. Self-assessed VAS-based adherence was stable over time at 94.0-96.3%. Similarly, MMAS score (maximum 4) was 3.8-3.9 at all visits, also reflecting high self-assessed adherence. In 269 patients using the RebiSmart® injection device, mean readout-based objective adherence was similarly high (93.0-98.4% throughout visits). At last available visit, VAS-based adherence was independent of participation in the PSP nursing service (93.1% with participation versus 91.7% without it). Adherence was also independent of injection method or disease-related measures, including fatigue, depression, cognition, and quality of life. The most frequent reason for the premature discontinuations (38.7% of patients) was "change of treatment" (10.0%). DISCUSSION We suggest that subgroups that may specifically benefit from PSP include patients who live alone, use multiple comedications, and are affected by cognitive impairment, depression, and/or fatigue. Further studies should investigate the potential usefulness of PSPs in these populations. CONCLUSIONS Very high adherence rates independent of the PSP nursing service over 1 year of treatment indicate that IFN beta-1a sc is an easy-to-use and well-tolerated disease-modifying drug.

Clinical case reviews and poster sessions in multiple sclerosis spasticity: Main outcomes and highlights

Background: Individuals with multiple sclerosis (MS) spasticity present with a range of symptoms and disability levels that are frequently challenging to manage.Summary: Clinical case reviews in treatment-resistant MS spasticity were presented in five country-specific sessions conducted in parallel at the MS Experts Summit. Attendees at the Norwegian session discussed early response to new treatments for severe spasticity and highlighted the importance of titrating THC:CBD oromucosal spray (Sativex ®) when adding it to baclofen. The French group focussed on MS symptoms and patient characteristics that interact with spasticity and agreed on a list of minimum ratings for diagnosis of MS spasticity symptoms. Attendees at the Spanish session concurred that THC:CBD oromucosal spray is effective and well tolerated as add-on therapy in treatment-resistant MS spasticity, particularly for pain, spasms and gait disturbances. The Italian group discussed the use of add-on THC:CBD oromucosal spray and other possible combination therapies for treatment-resistant MS spasticity. Attendees at the German session highlighted the need to address trigger factors for MS spasticity to reduce the potential for impact on activities of daily living (ADL) and quality of life (QoL). Three innovative studies of MS spasticity from the poster session were selected for closer review. The MOVE 1 EU epidemiological study indicated that, across western Europe, patients with MS spasticity continue to have unmet management needs. A literature review demonstrated that symptomatic relief of MS spasticity in patients who respond to THC:CBD oromucosal spray translates into sustainable improvements in ADL and QoL. Enriched-design studies of medications targeting the endocannabinoid system require careful interpretation due to possible pharmacodynamic 'priming', i.e. carry-over effects of successful active treatment during the enrichment phase.Key Messages: Sharing experiences of clinical practice, including experience with the use of THC:CBD oromucosal spray, may be useful to overcome some of the challenges in the overall management of patients with moderate to severe treatment-resistant MS spasticity

Adherence to Disease Modifying Drugs among Patients with Multiple Sclerosis in Germany: A Retrospective Cohort Study.

Long-term therapies such as disease modifying therapy for Multiple Sclerosis (MS) demand high levels of medication adherence in order to reach acceptable outcomes. The objective of this study was to describe adherence to four disease modifying drugs (DMDs) among statutorily insured patients within two years following treatment initiation. These drugs were interferon beta-1a i.m. (Avonex), interferon beta-1a s.c. (Rebif), interferon beta-1b s.c. (Betaferon) and glatiramer acetate s.c. (Copaxone).This retrospective cohort study used pharmacy claims data from the data warehouse of the German Institute for Drug Use Evaluation (DAPI) from 2001 through 2009. New or renewed DMD prescriptions in the years 2002 to 2006 were identified and adherence was estimated during 730 days of follow-up by analyzing the medication possession ratio (MPR) as proxy for compliance and persistence defined as number of days from initiation of DMD therapy until discontinuation or interruption.A total of 52,516 medication profiles or therapy cycles (11,891 Avonex, 14,060 Betaferon, 12,353 Copaxone and 14,212 Rebif) from 50,057 patients were included into the analysis. Among the 4 cohorts, no clinically relevant differences were found in available covariates. The Medication Possession Ratio (MPR) measured overall compliance, which was 39.9% with a threshold MPR≥0.8. There were small differences in the proportion of therapy cycles during which a patient was compliant for the following medications: Avonex (42.8%), Betaferon (40.6%), Rebif (39.2%), and Copaxone (37%). Overall persistence was 32.3% at the end of the 24 months observation period, i.e. during only one third of all included therapy cycles patients did not discontinue or interrupt DMD therapy. There were also small differences in the proportion of therapy cycles during which a patient was persistent as follows: Avonex (34.2%), Betaferon (33.4%), Rebif (31.7%) and Copaxone (29.8%).Two years after initiating MS-modifying therapy, only 30-40% of patients were adherent to DMDs
