Real-World Assessment of Quality of Life in Patients with Relapsing Remitting Multiple Sclerosis Treated with Teriflunomide for Two Years: Patient-Reported Outcomes from the AURELIO Study in Greece.

INTRODUCTION: Multiple sclerosis (MS) is a highly heterogeneous inflammatory disease of the central nervous system. Patient-reported outcomes (PROs) in a real-world clinical setting can provide detailed information about MS from the patient's perspective. PROs were used here to assess quality of life (QoL), treatment satisfaction, clinical efficacy, and safety outcomes in a Greek cohort of relapsing remitting MS (RRMS) patients treated with oral teriflunomide (14 mg/day). METHODS: AURELIO was a 2-year, prospective, observational study whose QoL primary endpoint was assessed with the Multiple Sclerosis Impact Scale (MSIS-29). Secondary endpoints included analyses of Patient Determined Disease Steps (PDDS), Treatment Satisfaction Questionnaire for Medication (TSQM), Expanded Disability Status Scale (EDSS), annualized relapse rate (ARR), adherence, and safety outcomes. RESULTS: AURELIO enrolled 282 patients (62.8% female; mean age 44.8 [SD ± 11] years; EDSS 2.0 [SD ± 1.6]; 44.6% treatment-naïve), with 212 patients (75%) remaining on treatment at study end. MSIS-29 total scores remained stable, while the MSIS-29 psychological scale showed significant improvement (p = 0.0015) at 2 years vs. baseline. TSQM scores at 2 years showed significant improvements in effectiveness (+ 6.6, p = 0.0001), convenience (+ 1.9, p = 0.0256), and global satisfaction (+ 8.1, p = 0.0001) vs. baseline. Disease progression was stable as indicated by non-significant changes in PDDS and EDSS vs. baseline. The ARR was low at 0.065, with a slightly higher ARR in previously treated (0.070) vs. naïve patients (0.058). Adherence was high at > 90%. Overall, 91 patients (32.3%) in the study reported a total of 215 safety events (32 serious, of which 21 were classified as mild-moderate). No new safety signals were observed. CONCLUSIONS: These data highlight the importance of PROs to facilitate personalized treatment strategies in MS. In line with other teriflunomide studies, AURELIO showed stable QoL, efficacy and safety outcomes, and good treatment satisfaction both in treatment-naïve and previously treated patients in this Greek cohort of patients with RRMS.

Impact of Body Mass Index on the Age of Relapsing-Remitting Multiple Sclerosis Onset: A Retrospective Study.

A BACKROUND: Multiple sclerosis (MS) is a complex chronic disease of the central nervous system (CNS). Body mass index (BMI), a component of metabolic syndrome (MetS), is considered among the risk factors for MS. However, its role in MS remains ambiguous. OBJECTIVE: To examine the impact of BMI on the age of onset in patients with relapsing-remitting MS (RRMS) in a Greek cohort. METHODS: Data from 821 Greek patients with RRMS were collected. The BMI values were considered as quartiles. Comparisons for the demographic characteristics between the quartiles were made by Pearson's chi-square test for the categorical variables and by ANOVA for the continuous variables. An overall p-value was calculated corresponding to trend for association. In case of significant association, further post-hoc analysis was performed in order to identify differences in demographic characteristics between specific BMI quartiles groups. Linear regression analyses were used to assess the relationship between BMI and age at onset of MS. RESULTS: Comparisons of participant characteristics by quartiles of BMI revealed that participants with the highest BMI had an older age of disease onset. Results from linear regression analysis showed that with each increase of 1 BMI unit, the age of RRMS onset increases by 0.255 (95% CI 0.136 to 0.374) years, p < 0.001. CONCLUSIONS: Patients with higher BMI, as a parameter of MetS, exhibit increased age of RRMS onset. Our results may present an alternative personalized approach for diagnosis, prognosis, and/or prevention of RRMS.

Seasonal adherence to, and effectiveness of, subcutaneous interferon ß-1a administered by RebiSmart® in patients with relapsing multiple sclerosis: results of the 1-year, observational GEPAT-SMART study.

BACKGROUND: Little is known about whether tolerability and adherence to treatment can be influenced by weather and temperature conditions. The objective of this study was to assess monthly and seasonal adherence to and safety of sc IFN-ß1a (Rebif®, Merck) in relapsing-remitting multiple sclerosis (RRMS) patients using the RebiSmart® electronic autoinjector. METHODS: A multicentre, prospective observational study in Greece in adult RRMS patients with EDSS < 6, under Rebif®/RebiSmart® treatment for ≤6 weeks before enrollment. The primary endpoint was monthly, seasonal and annual adherence over 12 months (defined in text). Secondary endpoints included number of relapses, disability, adverse events. RESULTS: Sixty four patients enrolled and 47 completed all study visits (Per Protocol Set - PPS). Mean annual adherence was 97.93% ± 5.704 with no significant monthly or seasonal variations. Mean relapses in the pre- and post- treatment 12-months were 1.1 ± 0.47 and 0.2 ± 0.54 (p < 0.0001, PPS). 10 patients (22%) showed 3-month disability progression, 19 (40%) stabilization and 18 (38%) improvement. EDSS was not correlated to pre- (r = 0.024, p = 0.87) or post-treatment relapses (r = 0.022, p = 0.88). CONCLUSION: High adherence with no significant seasonal or weather variation was observed over 12 months. While the efficacy on relapses was consistent with published studies, we could not identify a relationship between relapses and disability.

Multiple sclerosis, idiopathic dilated cardiomyopathy, and insulin-dependent diabetes mellitus: a common mechanism of irregular immune regulation.

BACKGROUND: Multiple sclerosis (MS), idiopathic dilated cardiomyopathy (DCM), and diabetes mellitus-1 (DM-1) are polygenic autoimmune diseases with a pivotal autoimmune component affecting young adults. They share a number of characteristics, thereby suggesting common underlying pathways or mechanisms. Typically, the aforementioned diseases are organ-specific autoimmune disorders of unknown etiology, but with strong evidence of tissue-destructive activity of the humoral and/or cellular immune system in the end-organ tissues affected (ie, the myelin components in MS, the myocytes of myocardium in DCM, and the insulin-secreting ß islets in DM-1). CASE REPORT: We herein describe a 35-year-old white Greek man who presented with coexisting MS, DCM, and DM-1 diagnosed over a period of 7 years. The patient was successfully treated and is asymptomatic until present time. CONCLUSION: The clustering of these 3 autoimmune diseases in our patient supports the concept of an immune-mediated damage in these diseases, an important aspect for an effective therapeutic choice by neurologists. However, the immunopathogenetic association between MS and other autoimmune remains speculative, thereby warranting further clarification.

Familial prevalence of autoimmune disorders in multiple sclerosis in Northern Greece.

OBJECTIVE: The objective of this study was to evaluate for up to 7 years the prevalence of autoimmune disorders among naïve (untreated) multiple sclerosis family members compared with a contemporary general control population in Northern Greece, in a prospective case-control study, and to examine the possible relationship between immunomodulatory treatment and the appearance of additional autoimmune disorders. METHODS: The patients and controls enrolled comprised 1383 patients with definite MS and 4392 relatives in their families and a total of 452 controls families with 1652 members. RESULTS: At baseline, 891 multiple sclerosis families with 3112 members (73 multiplex multiple sclerosis families with 292 members and 818 simplex families with 2820 members) and 355 control families with 1580 members were examined regarding whether they had any of 12 autoimmune diseases. The baseline affected multiplex plus simplex multiple sclerosis families, the family members and the coexistent additional autoimmune disorders were higher compared with controls. There was an increase in longitudinally affected multiple sclerosis families, multiple sclerosis family members and coexistent additional autoimmune disorders compared with respective findings at the baseline observation. Comparison analysis between two time point observations (after a mean 7.1 +/- 2.2 years) for each autoimmune disorder in overall multiple sclerosis family members revealed increased rates for longitudinal autoimmune Hashimoto's thyroiditis, Graves' disease, insulin-dependent diabetes mellitus, psoriasis and vitiligo (p = 0.02, p = 0.006, p = 0.0004, p = 0.05, and p = 0.05, respectively). Some 145 newly developed, longitudinally definite autoimmune cases were recognized in multiplex plus simplex multiple sclerosis families; 116 (80%) of these disorders were observed in patients with multiple sclerosis treated with immunomodulatory medications, and 68 of these 116 (58.6%) cases exhibited baseline positive autoreactive antibodies. Binary logistic regression analysis revealed that immunotherapy predisposes to autoimmunity (odds ratio 2.8, p < 0.001) independently of the presence of baseline autoantibodies and patients' gender. CONCLUSIONS: There is a longitudinally increased frequency of additional autoimmune disorders among multiple sclerosis family members, probably related to immunomodulatory therapy.

From the "little brain" gastrointestinal infection to the "big brain" neuroinflammation: a proposed fast axonal transport pathway involved in multiple sclerosis.

The human central nervous system (CNS) is targeted by different pathogens which, apart from pathogens' intranasal inoculation or trafficking into the brain through infected blood cells, may use a distinct pathway to bypass the blood-brain barrier by using the gastrointestinal tract (GIT) retrograde axonal transport through sensory or motor fibres. The recent findings regarding the enteric nervous system (often called the "little brain") similarities with CNS and GIT axonal transport of infections resulting in CNS neuroinflammation are mainly reviewed in this article. We herein propose that the GIT is the vulnerable area through which pathogens (such as Helicobacter pylori) may influence the brain and induce multiple sclerosis pathologies, mainly via the fast axonal transport by the afferent neurones connecting the GIT to brain.

Factors influencing the pre- and in-hospital management of acute stroke--data from a Greek tertiary care hospital.

In a prospective observational study, data on pre- and in-hospital management of acute stroke patients were collected from 100 consecutive patients admitted to the emergency room (ER) of Papageorgiou Hospital, a tertiary health care facility in Thessaloniki, Greece. Public emergency services were used by 58% of the patients, and 42% were brought by their relatives. 27% of the patients arrived within 1.5 h, 45% within 3 h, and 71% within 6 h from symptom onset. The median interval from ER arrival to examination by a board-certified neurologist was 20 min (range 5-40 min). Time from ER arrival until brain CT scan ranged from 17 min to 28 h, with a median of 1.7 h. The majority (57%) of acute stroke patients reached hospital and received adequate diagnostic and treatment within 6 h, and approximately 30% even within 3 h from symptom onset. Thus, and in contrast to widespread perception, there is a time window for hyper-acute stroke treatment in Greek public hospitals. However, the fraction of patients eligible for acute treatment may be increased by shortening both the interval from symptom onset to hospital arrival, and also the door-to-CT interval.
