In multiple sclerosis (MS), half of affected people are unemployed within 10 years of diagnosis. The aim of this study was to assess the economic impact of MS in adult subjects with ...relapsing-remitting MS (RRMS) and primary progressive MS (PPMS).
A multicenter, non-interventional, cross-sectional study was conducted. The Expanded Disability Status Scale (EDSS) and the 23-item Multiple Sclerosis Work Difficulties Questionnaire (MSWDQ-23) were used to assess disability and work performance, respectively. Only indirect costs were considered using the human capital method, including work costs. Professional support costs and informal caregivers' costs were also estimated.
A total of 199 subjects were studied (mean age: 43.9 ± 10.5 years, 60.8% female, 86.4% with RRMS). Median EDSS score was 2.0 (interquartile range: 1.0-3.5) and median MSWDQ-23 total score was 31.5 (15.2, 50.0). The number of employed subjects decreased after MS diagnosis from 70.6 to 47.2%, and the number of retired people increased (23.6%). Mean age of retirement was 43.6 ± 10.5 years. Ten percent of the population had sick leaves (absenteeism was seen in 90.9% of the student population and 30.9% of the employed population). Professional support in their daily life activities was needed in 28.1% of subjects. Costs for sick leave, work absenteeism, premature retirement and premature work disability/pensioner were €416.6 ± 2030.2, €763.4 ± 3161.8, €5810.1 ± 13,159.0 and €1816.8 ± 9630.7, respectively. Costs for professional support and informal caregiving activities were €1026.93 ± 4622.0 and €1328.72, respectively.
MS is responsible for a substantial economic burden due to indirect and informal care costs, even in a population with low physical disability.

Hopelessness is a risk factor for depression and suicide. There is little information on this phenomenon among patients with relapsing-remitting multiple sclerosis (RRMS), one of the most common ...causes of disability and loss of autonomy in young adults. The aim of this study was to assess state hopelessness and its associated factors in early-stage RRMS.
A multicenter, non-interventional study was conducted. Adult patients with a diagnosis of RRMS, a disease duration ≤ 3 years, and an Expanded Disability Status Scale (EDSS) score of 0-5.5 were included. The State-Trait Hopelessness Scale (STHS) was used to measure patients´ hopelessness. A battery of patient-reported and clinician-rated measurements was used to assess clinical status. A multivariate logistic regression analysis was conducted to determine the association between patients' characteristics and state hopelessness.
A total of 189 patients were included. Mean age (standard deviation-SD) was 36.1 (9.4) years and 71.4% were female. Median disease duration (interquartile range-IQR) was 1.4 (0.7, 2.1) years. Symptom severity and disability were low with a median EDSS (IQR) score of 1.0 (0, 2.0). A proportion of 65.6% (n=124) of patients reported moderate-to-severe hopelessness. Hopelessness was associated with older age (p=0.035), depressive symptoms (p=<0.001), a threatening illness perception (p=0.001), and psychological and cognitive barriers to workplace performance (p=0.029) in the multivariate analysis after adjustment for confounders.
Hopelessness was a common phenomenon in early-stage RRMS, even in a population with low physical disability. Identifying factors associated with hopelessness may be critical for implementing preventive strategies helping patients to adapt to the new situation and cope with the disease in the long term.
OBJECTIVE:To determine the presence of widespread pressure hyperalgesia in multiple sclerosis (MS) patients with and without pain and its association with pain and fatigue.
METHODS:A total of 108 ...individuals with definite MS, 49 men and 59 women (mean age, 44±8 y) and 108 age-matched and sex-matched pain-free controls (mean age, 44±9 y) were included. Fifty patients (n=58, 54%) reported pain and 50 (46%) did not. Pressure pain threshold (PPT) was bilaterally assessed over supraorbital, infraorbital, mental, median, radial and ulnar nerve trunks, C5-C6 joint, second metacarpal, and tibialis anterior muscle by an assessor blinded to the patient’s condition. The intensity of pain was assessed with a numerical pain rate scale (0 to 10), fatigue was determined with the Fatigue Impact Scale, and depression was evaluated with the Beck Depression Inventory.
RESULTS:The analyses of covariance revealed that PPT were significantly decreased bilaterally over the supraorbital, infraorbital, mental, median, ulnar and radial nerve trunks, C5-C6 joint, second metacarpal, and tibialis anterior muscles in patients with MS compared with pain-free controls (all, P<0.001). No significant differences existed between MS patients with pain and those without pain (all P>0.944). Patients with pain exhibited higher fatigue and depression than those patients without pain (P<0.05). PPT was not associated with any clinical variable, that is, pain, depression, or fatigue.
CONCLUSIONS:Our study found widespread pressure pain hyperalgesia in individuals with MS as compared with pain-free controls. No differences existed between MS patients with pain and those without pain in the presence of widespread pressure sensitivity. Current results suggest that MS is associated with sensory hyperexcitability of the central nervous system or dysfunction in endogenous pain modulatory systems.
Multiple sclerosis (MS) is a demyelinating disorder of the central nervous system (CNS) but the causes have not been defined. The disease process appears to involve interplay between environmental ...factors and certain susceptibility genes. It is likely that the identification of the exact etiological mechanisms will permit the development of preventive and curative treatments. Evaluation of several diseases found to be more often associated than by chance alone may reveal clues to the etiology of those disorders. An association between MS and inflammatory bowel diseases (IBD) was suggested by the observation of an increased incidence of IBD among MS patients. A problem in the interpretation of the data rests, in part, with the observation that abnormal findings in brain magnetic resonance imaging (MRI) may be reported as MS in IBD patients. Defining the limits between incidental MRI findings and findings compatible with MS has resulted in further exploration of this possible association.
Multiple sclerosis is one of the most common causes of neurological disability in young adults with major consequences for their autonomy and capacity to maintain employment.
The aim of this study ...was to assess the impact on work productivity in early-stage relapsing-remitting multiple sclerosis (RRMS).
A multicenter, non-interventional study was conducted. Adult patients with a diagnosis of RRMS, a disease duration ≤ 3 years, and an Expanded Disability Status Scale (EDSS) score of 0–5.5 were included. Absenteeism, presenteeism, and unpaid work loss due to RRMS were measured using the Valuation of Lost Productivity (VOLP) questionnaire. The EDSS, SymptoMScreen, 5-item Modified Fatigue Impact Scale, Hospital Anxiety and Depression Scale, Symbol Digit Modalities Test, and Multiple Sclerosis Work Difficulties Questionnaire were used to gather information on disability, patients’ perception of symptom severity, fatigue, mood/anxiety, cognition, and problems in the workplace, respectively. Associations between the VOLP and clinical and work outcomes were analyzed using Spearman's rank correlations.
A total of 189 patients were included. Mean age (SD) was 36.1 ± 9.4 years and 71.4% were female. Mean disease duration was 1.2 ± 0.8 years. Median EDSS score was 1.0 (IQR 0, 2.0). One hundred thirty patients (68.8%) were working for pay or self-employed. Fifty-three patients (40.8%) reported absence from work in the past 3 months with an average of 14.3 absent workdays. Their health problems resulted in the loss of 3.4% of their actual work time in the past 7 days. Thirty patients got help (11.8 h) with their unpaid work activities in the past 7 days. Absenteeism was significantly correlated with anxiety and depression (rho=0.298 and 0.291, p<0.001), fatigue (rho=0.214, p = 0.014), and symptom severity (rho=0.213, p = 0.015). Presenteeism was significantly correlated with fatigue (rho=0.375, p<0.001), symptom severity (rho=0.373, p<0.001), depression (rho=0.263, p = 0.008), and disability (rho=0.215, p = 0.031).
Productivity loss even in a RRMS population with short disease duration stresses the need for more efficient treatment control of disease activity from earlier stages.
We assessed the role of age and disease activity as new factors contributing to establish the risk of progressive multifocal leucoencephalopathy in multiple sclerosis patients treated with ...natalizumab in 36 University Hospitals in Europe. We performed the study in 1,307 multiple sclerosis patients (70.8% anti-John Cunninghan virus positive antibodies) treated with natalizumab for a median time of 3.28 years. Epidemiological, clinical, and laboratory variables were collected. Lipid-specific IgM oligoclonal band status was available in 277 patients. Factors associated with progressive multifocal leucoencephalopathy onset were explored by uni- and multivariate logistic regression.
Thirty-five patients developed progressive multifocal leucoencephalopathy. The multivariate analysis identified anti-John Cunninghan virus antibody indices and relapse rate as the best predictors for the onset of this serious opportunistic infection in the whole cohort. They allowed to stratify progressive multifocal leucoencephalopathy risk before natalizumab initiation in individual patients area under the curve (AUC) = 0.85. The risk ranged from <1/3,300 in patients with anti-John Cunninghan virus antibody indices <0.9 and relapse rate >0.5, to 1/50 in the opposite case. In patients with lipid-specific IgM oligoclonal bands assessment, age at natalizumab onset, anti-John Cunninghan virus antibody indices, and lipid-specific IgM oligoclonal band status predicted progressive multifocal leucoencephalopathy risk (AUC = 0.92). The absence of lipid-specific IgM oligoclonal bands was the best individual predictor (OR = 40.94). The individual risk ranged from <1/10,000 in patients younger than 45 years at natalizumab initiation, who showed anti John Cunningham virus antibody indices <0.9 and lipid-specific IgM oligoclonal bands to 1/33 in the opposite case.
In a perspective of personalized medicine, disease activity, anti-lipid specific IgM oligoclonal bands, anti Jonh Cunninghan virus antibody levels, and age can help tailor natalizumab therapy in multiple sclerosis patients, as predictors of progressive multifocal leucoencephalopathy.
We review the evidence for a link between multiple sclerosis (MS) and two of the most common primary headache disorders: tension-type headache and migraine. We argue that the association between ...migraine and MS is biologically plausible and is confirmed by most studies. We discuss possible explanations for the association. First, we consider the possibility that the association is spurious. Next, we consider unidirectional causal models in which one of the conditions increases the risk of the other. A bidirectional model would suggest that each disease predisposes to the other. Alternatively, genetic or environmental risk factors shared by each condition may account for the association between them. We also address the question of whether coexisting migraine or tension-type headache in a patient with MS affects the symptom profile, clinical course, and radiographic characteristics of MS.
OBJECTIVES:To investigate the roles of 2 polymorphisms of the tumor necrosis factor (TNF) receptor superfamily member 1A (TNFRSF1A) gene, rs1800693 (a common variant) and rs4149584 (a coding ...polymorphism that results in an amino acid substitution—R92Q), as genetic modifiers of multiple sclerosis (MS), and to evaluate their potential functional implications in the disease.
METHODS:The effects of rs1800693 and rs4149584 on 2 measures of disease severity, age at disease onset and Multiple Sclerosis Severity Score, were analyzed in 2,032 patients with MS. In a subgroup of patients, serum levels of the soluble form of TNF-R1 (sTNF-R1) were measured by ELISA; mRNA expression levels of the full-length TNF-R1 and Δ6-TNF-R1 isoform were investigated in peripheral blood mononuclear cells (PBMC) by real-time PCR; cell surface expression of the TNF-R1 was determined in T cells by flow cytometry.
RESULTS:For rs4149584, R92Q carriers were younger at disease onset and progressed slower compared to noncarriers. However, no association with disease severity was observed for rs1800693. Serum levels of sTNF-R1 and mRNA expression levels of the full-length receptor were significantly increased in patients with MS carrying the R92Q mutation (p = 0.003 and p = 0.011, respectively), but similarly distributed among rs1800693 genotypes; cell surface TNF-R1 expression in T cells did not differ between rs4149584 and rs1800693 genotypes. The truncated soluble Δ6-TNF-R1 isoform was identified in PBMC from patients carrying the risk allele for rs1800693.
CONCLUSIONS:These findings suggest that both rs1800693 and rs4149584 TNFRSF1A polymorphisms have functional consequences in the TNF-R1.
•Patients’ preferences should be considered in RRMS treatment decisions.•We aimed to understand factors driving status quo bias in early-stage RRMS patients.•Over forty percent of patients suffer ...cognitive delays in the early stages of RRMS.•Despite evidence of disease progression, patients tend to maintain their treatment.•Disease severity perception and cognitive delays affect patients’ treatment choices.
The evolving therapeutic landscape requires more participation of patients with relapsing remitting multiple sclerosis (RRMS) in treatment decisions. The aim of this study was to assess the association between patient's self-perception, cognitive impairment and behavioral factors in treatment choices in a cohort of patients at an early stage of RRMS.
We conducted a multicenter, non-interventional study including adult patients with a diagnosis of RRMS, a disease duration ≤18 months and receiving care at one of the 21 participating MS centers from across Spain. We used patient-reported measures to gather information on fatigue, mood, quality of life, and perception of severity of their MS. Functional metrics (Expanded Disability Status Scale EDSS, cognitive function by the Symbol Digit Modalities Test SDMT, 25-foot walk test) and clinical and radiological data were provided by the treating neurologist. The primary outcome of the study was status quo (SQ) bias, defined as participant's tendency to continue taking a previously selected but inferior treatment when intensification was warranted. SQ bias was assessed based on participants treatment preference in six simulated RRMS case scenarios with evidence of clinical relapses and radiological disease progression.
Of 189 participants who met the inclusion criteria, 188 (99.5%) fully completed the study. The mean age was 36.6 ± 9.5 years, 70.7% female, mean disease duration: 1.2 ± 0.8 years, median EDSS score: 1.0 IQR=0.0–2.0). Overall, 43.1% patients (n = 81/188) had an abnormal SDMT (≤49 correct answers). SQ bias was observed in at least one case scenario in 72.3% (137/188). Participant's perception of their MS severity was associated with higher SQ bias (β coeff 0.042; 95% CI 0.0074–0.076) among those with delayed cognitive processing. Higher baseline EDSS and number of T2 lesions were predictors of delayed processing speed (OR EDSS=1.57, 95% CI: 1.11–2.21, p = 0.011; OR T2 lesions=1.50, 95% CI: 1.11–2.03, p<0.01). Bayesian multilevel model accounting for clustering showed that delayed cognitive processing (exp coeff 1.06; 95% CI 1.04–1.09) and MS symptoms severity (exp coeff 1.28; 95% CI 1.22–1.33) were associated with SQ bias.
Over 40% of patients in earlier stages of RRMS experience delays in cognitive processing that might affect their decision-making ability. Our findings suggest that patients' self-perception of disease severity combined with a delay in cognitive processing would affect treatment choices leading to status quo bias early in the course of their disease.
