Effectiveness of Dimethyl Fumarate in Real-World Clinical Practice and Strategy to Minimize Adverse Effects and Use of Healthcare Resources.

BACKGROUND: Dimethyl fumarate (DMF) has shown efficacy in reducing relapse rates in patients with multiple sclerosis (MS). However, associated adverse effects (AE) such as gastrointestinal (GI) AE, flushing and lymphopenia are the main cause of treatment discontinuation. The aim of this study was to evaluate the effectiveness of DMF, and to assess strategies to reduce treatment discontinuation rates in routine clinical practice. PATIENTS AND METHODS: Ninety patients started DMF treatment between August 2015 and February 2020. Prior to DMF therapy, patients received written information regarding treatment and the management of AE, along with medical prescriptions. Clinical and analytical data were collected at clinical visits performed at least 6-monthly, and disease progression was evaluated by brain magnetic resonance imaging (MRI). RESULTS: Prior to DMF, 78.7% of patients had an annualized relapse rate (ARR) of 1.07 (range: 1-3) and median Expanded Disability Status Scale (EDSS) score of 1.0 (range: 0-2). At final follow-up, ARR and median EDSS scores were significantly reduced to 0.09 (range: 0-2; p< 0.001) and 0 (range: 0-1.625; p< 0.001), respectively. Just over one quarter of patients with brain MRI (26.8% of 71 patients) showed improvement in disease activity based on MRI evaluation. Lymphopenia was associated with previous treatment lines (p=0.042) and longer disease duration (p=0.032). A total of twelve patients abandoned DMF treatment, mainly due to lymphopenia (7.9%), but none did it because of GI AE or flushing. CONCLUSION: In our series, DMF showed high clinical and radiological efficacy. Providing patients with complete information prior to treatment on the management of associated AE helps them to better understand what to expect, improves tolerance and reduces clinical and telephone consultations, which may help to reduce the use and cost of healthcare resources.

Predictors of burden and depression among caregivers of relapsing-remitting MS patients in Spain: MS Feeling study.

AIM: To assess potential predictors for burden and depression among caregivers of relapsing-remitting multiple sclerosis patients in Spain. Family functioning and social support were also assessed. PATIENTS & METHODS: Multicenter and cross-sectional study in relapsing-remitting multiple sclerosis adult patients and their respective informal caregivers (n = 180). Assessment performed: Zarit Scale (Burden), Center for Epidemiologic Studies Depression-7 Scale (depression), Family APGAR (Adaptation, Partnership, Growth, Affection, Resolve) Questionnaire (family functioning) and Duke UNC-11 Functional Social Support Questionnaire (social support). Multivariate logistic regression analysis assessed burden and depression predictors among caregivers. RESULTS: Caregivers suffered burden (19.4%) and depression (20.6%) and perceived poor social support (9.4%) and family dysfunction (10.6%). Burden predictors were patient's degree of disability, caregiver time and number of medications administered to patient. Depression predictors were patient's age and daily caregiving time. CONCLUSION: The factors reported here could help clinicians to identify caregiver groups particularly at risk of burden and depression for timely intervention.

Long-term effectiveness of glatiramer acetate in clinical practice conditions.

Glatiramer acetate currently represents one of the main treatments for relapsing-remitting multiple sclerosis (RRMS). However, the information available about its long-term effect in clinical practice is still limited. Thus, this multicenter retrospective cohort study aimed to assess the long-term effectiveness of glatiramer acetate in this setting. The study population included RRMS patients treated with glatiramer acetate for at least 5 years after its marketing authorization and the primary endpoint was long-term clinical effectiveness, defined as absence of disability progression for at least five consecutive years. A total of 149 patients were included into the study, who had received glatiramer acetate for a mean of 6.9 ± 1.4 years (5 years, n=149; 6 years, n=112; 7 years, n=63; 8 years, n=32; 9 years, n=21). More than 85% of patients remained free from disability progression through years 1 to 9 of glatiramer acetate treatment, and 75.2% showed absence of disability progression for at least five consecutive years. Expanded Disability Status Scale (EDSS) scores were maintained, with most patients showing stable/improved EDSS and 92.6% sustaining EDSS <6. Decreased annual relapse rates and increased proportion of relapse-free patients were maintained during the whole glatiramer acetate treatment compared to the year prior to its authorization (p<0.001). The number of gadolinium-enhanced T1-weighted lesions also decreased from pre-glatiramer-acetate assessment to last follow-up whilst on glatiramer acetate (p<0.05). In conclusion, administration of glatiramer acetate shows long-term clinical effectiveness for RRMS treatment; its effect under clinical practice conditions slowed disability progression and reduced relapse occurrence for up to 9 years.
