Multiple Sclerosis Patients

Multiple sclerosis (MS) is a chronic illness of the central nervous system, with a highly variable clinical course. Available therapies are only partially effective and as a consequence treatment patterns between patients can be varied. Longitudinal databases consisting of large cohorts where successive and sequential data is collected may reveal disease and treatment characteristics not apparent when data is gathered during clinical trials that consist usually of relatively homogeneous patients followed for short durations. We analysed data from the North American Research Committee on Multiple Sclerosis registry, a self-reported database, to assess MS patient characteristics and treatment patterns, with a focus on veterans. We show that the Veteran Healthcare Administration (VHA) system of medical centres care for a greater number of patients with higher average disability but not necessarily patients who report primary progressive or actively worsening disease. We also show that the VHA medical centres appear to better provide multidisciplinary care, particularly in the areas of social work, physical therapy and urology. In general, treatment patterns for symptomatic therapies follow similar patterns across veterans and non-veterans groups. Treatment patterns for immunomodulatory agents suggest that VHA veterans use IMA less frequently than either non-VHA veterans or non-veterans.

Multiple Sclerosis Patients

Multiple sclerosis is the most frequent disease of the central nervous system. An increase in multiple sclerosis frequency was registered in several countries including Russia. This may be associated with better multiple sclerosis diagnosis and treatment, better data collection and real increase in multiple sclerosis incidence. Early disability and its rapid progression emphasize the medico-social importance of multiple sclerosis. Neuropsychological disturbances are often observed in multiple sclerosis, being one of the important components in the formation of clinical disease. 43 patients living in the North region with definite multiple sclerosis and mild or moderate disability were tested with expended neuropsychological, neurological and study of quality of life. The purpose of the study was to analyze the role of cognitive, emotional and personal peculiarities at multiple sclerosis on quality of life. To assess quality of life the authors used SF-36. The results of this study of quality of life revealed significant differences in the physical, role and social components depending on the cognitive peculiarities.

The objective of this study was to characterize the population of multiple sclerosis (MS) patients suffering from spasticity and to evaluate treatment patterns, including intrathecal baclofen (ITB) delivery, related to patient quality of life (QOL). We conducted a cross-sectional, two-level study using data from the Patient Registry of the North American Research Committee on MS (NARCOMS). In addition, we surveyed a subgroup of 198 preselected patients who are using ITB (ITBG) and a random sample of 315 oral drug users (ORALG). Among the registrants, 16% reported no spasticity, 31% minimal, 19% mild, 17% moderate (frequently affects activities), 13% severe (daily forced to modify activities) and 4% total (prevents daily activities). Patients experiencing greater severity included by proportion males, and those older and with longer duration of MS. QOL scores decreased inversely with severity. In the focused survey, ITBG reported lower levels of spasticity than ORALG, less stiffness in the legs, less pain and fewer spasms at any time. They scored significantly lower in the SF-36 physical component, yet reported less fatigue on the MFIS scale. Prevalence data reveal that one third of MS patients modify or eliminate daily activities as a result of spasticity. Treatment of spasticity can significantly impact QOL parameters by reducing spasms, pain and fatigue.

Previous work suggested that veterans with multiple sclerosis (MS) treated through the Veterans Health Administration (VHA) had greater access to multidisciplinary care than veterans treated elsewhere. It is unknown whether other VHA-related differences in processes of MS care exist. Using the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry, we aimed to compare bladder management reported by veterans who receive care through the VHA (VHA veterans) and those who do not (non-VHA veterans). In 2005, NARCOMS participants completed the Urogenital Distress Inventory–6 (UDI-6) and reported urologic investigations and treatments. Using multivariable logistic regression, we assessed the independent association of VHA care with investigations or treatments. A total of 1247 veterans with MS responded to the questionnaire, of whom 1230 (98.6%) reported where they received their health care. Of these, 583 (47.4%) received some or all of their care through the VHA. After adjustment for demographic and clinical factors, VHA veterans more frequently reported undergoing urologic investigations than non-VHA veterans (adjusted odds ratio, 2.02; 95% confidence interval, 1.55–2.61). VHA veterans more frequently reported using pharmacologic and nonpharmacologic interventions than non-VHA veterans. Differences exist in the processes of MS bladder care between the VHA and elsewhere; this variation suggests the availability of opportunities to optimize such care.

Цель исследования - изучение особенностей восприимчивости пациентов с рассеянным склерозом (РС) к холодовому воздействию с помощью функциональных тестов, характеризующих функцию терморегуляции. Как известно, РС - хроническое прогрессирующее аутоиммунное заболевание центральной нервной системы мультифакториальной природы, более часто встречающееся в регионах с холодным и влажным климатом. Нарушения терморегуляции вследствие автономной дисфункции являются характерным признаком РС, вместе с тем участию холодового фактора в развитии заболевания не придается существенного значения. Методика. Обследовано 32 пациента (17 мужчин и 15 женщин, средний возраст 29,6 ± 4,2 года) с установленным диагнозом: РС ремиттирующе-рецидивирующая форма течения (средняя продолжительность заболевания - 4,2 ± 2,7 года) и 18 практически здоровых лиц группы сравнения. Восприятие холода оценивали с помощью визуально-аналоговой шкалы. Продолжительность холод-индуцированной вазоконстрикции после локального холодового теста изучали по данным инфракрасной термометрии. Вегетативную регуляцию вазомоторных реакций оценивали по результатам анализа вызванных кожных вегетативных потенциалов (ВКВП). Результаты. На основе анализа самооценки восприятия холода у пациентов с РС показана низкая переносимость холодового фактора. При проведении локального холодового теста отмечено замедление восстановления температуры кожи кисти, что характерно для усиления холод-индуцированной вазоконстрикции. В группе пациентов с РС выявлено снижение параметров ВКВП ладоней и стоп, свидетельствующее о дефиците нейрогенного контроля терморегуляционных сосудистых реакций. Заключение. У пациентов с РС выявлены нарушения механизмов терморегуляции при действии холода, что обусловливает высокую индивидуальную восприимчивость к холоду у данной категории лиц. Сопоставление результатов анализа механизмов индивидуальной холод-индуцированной реактивности у пациентов с РС с данными эпидемиологических исследований приводит к заключению о потенциальном модулирующем влиянии холодового фактора на течение РС. The purpose of the present study was focused on the evaluation of the sensitivity to cold in multiple sclerosis (MS) patients by means of functional thermoregulatory based tests. MS is known to be a chronic autoimmune progressive disease of the central nervous system of multifactor origin that is very common in regions with cold and humid climate. Disorder of thermoregulation caused by autonomic dysfunction is a typical feature of MS, however the role of the cold in the disease development is still underestimated. Methods. Thirty two MS patients (17 males, 15 females, mean age 29,6 ± 4,2 years) with the remittent form of the disease (mean disease duration 4,2 ± 2,7 years) and 18 age-matched healthy controls volunteered to participate in this study. Susceptibility to cold was analyzed with the use of visual-analogous scale. The duration of cold-induced vasoconstriction after local cold test was estimated using by infrared thermometry. Autonomic regulation of vasomotor reactions was investigated with the help of the skin sympathetic response (SSR) analysis. Results. The analysis of self-reported perception of the cold in MS patients showed their low tolerance to cold. Slow recovery of the skin temperature of the hand in the local cold test observed in MS patients was considered as the aggravated cold-induced vasoconstriction. The decreased SSR in the hands and feet in MS patients was found that indicates the deficit of the neurogenic control of thermoregulatory vasomotor reactions. Conclusion. The results obtained demonstrate the impairment of thermoregulation under cold in MS patients that leads to higher individual susceptibility to cold of this group. Comparing of the data found in this study on the mechanisms of the individual cold-induced reactivity in MS patients with epidemiological surveys enable to conclude that cold environment has potential modulating effect of on the course of MS.

Background: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) are approved for their ability to reduce disease activity, namely clinical relapses and signal changes on magnetic resonance imaging (MRI). Disease activity appears age dependent. Thus, the greatest benefit would be expected in younger people with MS (PwMS) whereas benefits in the elderly are uncertain. Methods: Real-world data were obtained from PwMS from the North American Research Committee on Multiple Sclerosis (NARCOMS) registry and the US Department of Veterans Affairs Multiple Sclerosis Surveillance Registry (MSSR). Results: 6948 PwMS were surveyed from NARCOMS, and the MSSR had 1719 participants. In younger adult PwMS 40-years old or less, 183 (61.4%) in NARCOMS and 179 (70.5%) in the MSSR were prescribed DMTs. Among PwMS over age 60, 1575 (40.1%) in NARCOMS and 239 (36.3%) in the MSSR were prescribed DMTs. More PwMS in the age group of 31–40 ( p = 0.035) and 41–50 ( p = 0.001) in the MSSR were using DMTs compared with PwMS of the same age groups in NARCOMS. Conclusion: These findings suggest that DMTs are under-utilized in the younger population and continue to be commonly prescribed in the elderly. Broader access may explain the higher prescription rate of DMTs in US veterans.

The North American Research Committee on Multiple Sclerosis (NARCOMS) Registry is a multiple sclerosis (MS) self-report registry with more than 24 000 participants. Participants report disability status upon enrolment, and semi-annually using Performance Scales (PS), Patient Determined Disease Steps (PDDS) and a pain question. In November 2000 and 2001, we also collected the Pain Effects Scale (PES). Our aim was to validate the NARCOMS pain question using the PES as our criterion measure. We measured correlations between the pain question and age, disease duration, various PS subscales and PDDS to assess construct validity. We correlated pain question responses in participants who reported no change in PDSS or the PS subscales between questionnaires to determine test—retest reliability. We measured responsiveness in participants who reported a substantial change in the sensory, spasticity PS subscales. The correlation between the pain question and PES was r=0.61 in November 2000, and r=0.64 in November 2001 (both P<0.0001). Correlations between the pain question and age, and disease duration were low, indicating divergent validity. Correlations between the pain question and spasticity, sensory PS subscales and PDSS were moderate, indicating convergent validity. Test—retest reliability was r=0.84 (P<0.0001). Responsiveness was 70.7%. The pain question is a valid self-report measure of pain in MS.

Multiple sclerosis (MuS) is an autoimmune disease of the central nervous system characterized by neuroinflammation, neurodegeneration, and degradation of the myelin sheath. Epidemiological studies have shown that the female gender is more susceptible than the male gender to MuS development, with a female-to-male ratio of 2:1. Despite this high onset, women have a better prognosis than men, and the frequency of the relapsing phase decreases during pregnancy, while it increases soon after birth. Therefore, it is interesting to investigate hormonal fluctuations during pregnancy and whether they correlate with metabolic signatures. To gain a deeper inside into the biochemical mechanism of such a multifactorial disease, we adopted targeted metabolomics approaches for the determination of many serum metabolites in 12 pregnant women affected by MuS by mass spectrometry analysis. Our data show a characteristic hormonal fluctuation for estrogens and progesterone, as expected. They also highlight other interesting hormonal alterations for cortisol, corticosterone, 11-deoxycortisol, 4-androstene-3,17-dione, testosterone, and 17α-hydroxyprogesterone. Furthermore, a negative correlation with progesterone levels was observed for amino acids and for acylcarnitines, while an imbalance of different sphingolipids pathways was found during pregnancy. In conclusion, these data are in agreement with the characteristic clinical signs of MuS patients during pregnancy and, if confirmed, they may add an important tessera in the complex mosaic of maternal neuroprotection.

Disease Modifying

Injectable first-line disease-modifying therapies (DMTs) for multiple sclerosis (MS) are generally prescribed for continuous use. Accordingly, the various factors that influence patient persistence with treatment and that can lead some patients to switch medications or discontinue treatment may affect clinical outcomes. Using data from the North American Research Committee on Multiple Sclerosis (NARCOMS) database, this study evaluated participants' reasons for discontinuation of injectable DMTs as well as the relationship between staying on therapy and sustained patient-reported disease progression and annualized relapse rates. Participants selected their reason(s) for discontinuation from among 16 possible options covering the categories of efficacy, safety, tolerability, and burden, with multiple responses permitted. Both unadjusted data and data adjusted for baseline age, disease duration, disability, and sex were evaluated. Discontinuation profiles varied among DMTs. Participants on intramuscular interferon beta-1a (IM IFNβ-1a) and glatiramer acetate (GA) reported the fewest discontinuations based on safety concerns, although GA was associated with reports of higher burden and lower efficacy than other therapies. Difficulties with tolerability were more often reported as a reason for discontinuing subcutaneous (SC) IFNβ-1a than as a reason for discontinuing IM IFNβ-1a, GA, or SC IFNβ-1b. In the persistent therapy cohort, less patient-reported disability progression was reported with IM IFNβ-1a treatment than with SC IFNβ-1a, IFNβ-1b, or GA. These findings have relevance to clinical decision making and medication compliance in MS patient care.

The Impact

Background: The multifunctional cytokine interleukin-6 (IL-6) is involved in inflammatory processes in the central nervous system. It is well documented that amount of IL-6 is increased in serum, cerebrospinal fluid and central nervous system lesions of patients with multiple sclerosis. A single nucleotide polymorphism at position -174 in the IL-6 gene promotor appears to influence IL-6 expression. Recently, several researchers have focused on HLA-DRB alleles, specifically HLA-DRB1*1501, as a potential risk allele in the pathogenesis of multiple sclerosis. Objective: To investigate the possible influence of IL-6/-174 polymorphisms on susceptibility to multiple sclerosis and its integration with HLA-DRB1*1501. Genomic DNA was extracted from whole blood of 345 patients with multiple sclerosis and 426 control subjects. Method: The SSP-PCR method was used to determine genotypes and Fisher’s exact test was applied to determine differences between groups. HLA-DRB1*1501 was observed more frequently among multiple sclerosis patients compared with healthy subjects (45% and 34%, respectively; OR = 1.6, 95% CI = 1.2—2.2, p = 0.0018). At the IL-6/-174 position, the G allele had higher frequency among multiple sclerosis patients compared with controls (77% and 70%, respectively; OR = 1.4, 95% CI = 1.1—1.8, p = 0.0038). This difference was more significant among HLA-DRB1*1501-positive patients and controls (81% and 67%, respectively; OR = 1.9, 95% CI = 1.5—2.5, p < 0.0001). Results: Our results have shown that the G allele at the IL-6/-174 promoter polymorphism may be associated with development of multiple sclerosis in this population, and may be strengthened by HLA-DRB1*1501. Conclusions: We suggest more studies to confirm these results in other populations.

Term Response

Multiple sclerosis (MS) is a common neurological disability of the central nervous system. Immune-modulatory therapy with interferon-β (IFN-β) has been used as a first-line treatment to prevent relapses in MS patients. While the therapeutic mechanism of IFN-β has not been fully elucidated, the data of microarray experiments that collected longitudinal gene expression profiles to evaluate the long-term response of IFN-β treatment have been analyzed using statistical methods that were incapable of dealing with such data. In this study, the GeneRank method was applied to generate weighted gene expression values and the monotonically expressed genes (MEGs) for both IFN-β treatment responders and nonresponders were identified. The proposed procedure identified 13 MEGs for the responders and 2 MEGs for the nonresponders, most of which are biologically relevant to MS. Our work here provides some useful insight into the mechanism of IFN-β treatment for MS patients. A full understanding of the therapeutic mechanism will enable a more personalized treatment strategy possible.
