RESUMO
BACKGROUND: The Expanded Disability Status Scale (EDSS) is widely used and accepted by regulatory agencies for the assessment of neurological disability secondary to Multiple Sclerosis. The "Expanded Disability Status Scale (EDSS) by phone" was developed to be a patient-reported telephone-based alternative for the assessment of EDSS functional system scores when a physical examination is not possible. The scale has been validated in multiple languages; however, its reliability has not been assessed in Brazilian Portuguese. METHODS: After cross-cultural translation and adaptation, 57 people with MS with a recent in-person visit (±6 months) were invited to answer the EDSS by phone scale on two occasions, 15 days apart. The agreement between scales (in-person and telephone-based) and between telephone-based assessments was evaluated using intraclass correlation coefficients (ICC) for absolute agreement and weighted Kappa coefficients. RESULTS: An excellent reliability was obtained for the agreement between the in-person and telephone assessments (ICC: 0.95, 95 %CI 0.92-0.97, Kappa: 0.83, 95 %CI 0.78-0.89) and between telephone-based assessments (ICC: 0.99, 95 %CI 0.98-0.99, Kappa: 0.93, 95 %CI 0.88-0.97). After stratification by disability level, the agreement between scales was less pronounced for subjects with an EDSS ≤ 4.0. CONCLUSION: this study offers evidence that supports the validity of the EDSS by phone questionnaire translated into Brazilian Portuguese, particularly for patients with higher EDSS scores.

Chronic pain is the most disability symptom related to multiple sclerosis (MS) brain lesions and can also generate anxiety and depression. There are no updated reports of the general prevalence of neuropathic pain, MS clinical types, sex dimorphism, and its association with depression and anxiety. The protocol was listed in PROSPERO (CRD42022303571). The article selection resulted in 24 studies with a low risk of bias. The prevalence of neuropathic pain in MS patients was 26.8% with higher levels of depression and anxiety. We also observed that female patients (74.2%) have a higher prevalence of neuropathic pain than males (28.9%). We showed the enhanced prevalence of neuropathic pain using the female and male data (58.9%) compared to the total prevalence (26.8%). In addition, the SPMS (40.3%) presented an increased prevalence of neuropathic pain compared to PPMS (15.6%). Thus, we demonstrated the association between neuropathic pain, depression and anxiety symptoms and the influence of diagnosis, age, disease score, and disease duration in the increased prevalence of neuropathic pain in MS patients.

Multiple sclerosis (MS) is a chronic neurodegenerative and autoimmune disease. Motor, sensory and cognitive deficits in MS are commonly accompanied by psychiatric disorders. Depression and anxiety affect the quality of life of MS patients, and the treatment is still not well-established. Prevalence rates in MS patients for depression and anxiety vary widely between studies. However, the prevalence of these psychiatric disorders in the subgroups of MS patients and their association with a disability has not been studied yet. Therefore, this systematic review and meta-analysis proposes to estimate the prevalence of depression and anxiety in MS and to perform subgroup analyses (study type, Extended Disability Status Scale/EDSS, duration of MS, region, type of MS) on observational studies. The protocol was registered in PROSPERO (4202125033). A computerized search on PubMed, EMBASE and Scopus for studies on depression and anxiety in MS was performed from 2015 to 2021, and 12 articles were included. Most of the studies in the meta-analysis had a low risk of bias. The prevalence of depression was 27.01% (MS), 15.78% (relapsing-remitting multiple sclerosis/RRMS), and 19.13% (progressive multiple sclerosis/PMS). For anxiety the prevalence was 35.19% (MS), 21.40% (RRMS), and 24.07% (PMS). The prevalence of depression/anxiety for patients with EDSS <3 was 26.69/45.56% and for EDSS >3 was 22.96/26.70%. Using HADS-A (8) the prevalence was 38.5% and for depression was 22.4%. Then, our study brought together current data regarding psychiatric disorders in MS patients, which are comorbidities that affect the quality of life of these patients.
RESUMO
BACKGROUND: Physical disability, cognitive impairment, depression, and fatigue are poorly understood in Latin American patients with multiple sclerosis following alemtuzumab infusion. OBJECTIVES: To describe Sustained changes in physical disability in an average 22-month follow-up period after alemtuzumab infusion, and which demographical or clinical variables modulate change in EDSS, and adverse events, changes in cognition, fatigue, and depressive symptoms after an average 15-month follow-up period. METHOD: Retrospective cohort observational study. Following the review of medical records, 23 patients with Relapsing Remitting Multiple Sclerosis treated with alemtuzumab were identified; of these, 17 had a baseline neuropsychological assessment and 12 had at least one follow-up neuropsychological assessment. RESULTS: Most of the patients presented a low level of physical disability, depression, fatigue, and cognitive impairment, which was more pronounced in the processing speed and visuospatial memory at baseline. Fifteen of 23 (65.2%) of patients showed disability improvement, 7 (30.1%) patients remained stable, and 1 (4.3%) patient worsened, and change was not influenced by age or baseline disability score. Twenty (87%) patients remained free of clinical relapses. Performance improved on the BVMT-R visual memory test, 9 (75%) remained stable or improved on the BICAMS, and 66.6% perceived decreased fatigue on the d-FIS. Adverse events occurred in 7 (30.1%) of patients, the most common were opportunistic infections in 2 (8.6%) patients, and one 29-year-old patient presented papillary thyroid carcinoma after infusion of the second course of alemtuzumab. CONCLUSIONS: Results suggest that treatment with alemtuzumab has a beneficial impact on disability, cognitive impairment, and perception of fatigue. The percentage and type of adverse events observed in the cohort are similar to those reported for other real-life studies.

BACKGROUND: Multiple Sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). B cells have an essential role in the disease pathogenesis and therefore selective B-cell depletion are commonly used to treat the disease. Rituximab (RTX), a chimeric anti-CD20 monoclonal antibody had demonstrated reduced inflammatory activity and radiological activity in MS patients. Due to economic constrains and treatment access limitations, RTX is often used as a treatment alternative in these patients. Here, we described our center experience in RTX -treated MS patients. METHODS: A single-center observational retrospective study was conducted in a Mexican cohort MS during 2010 to 2020. All patients had a confirmed MS diagnosis.All patients received fixed scheme involving induction with 1 g on day one and day 15, followed by 500 mg-1 g every six months for maintenance. Annual Relapse Rate (ARR), Progression index (PI), Expanded Disability Status Scale (EDSS) and MRI activity of the disease were evaluated. Comparison between naïve and non-naïve patients was also conducted. RESULTS: A total of 85 patients were included. The mean age at diagnosis was 33.13 (±8.90) years with 73 (85.9%) being RRMS. 39 (34.1%) were treatment-naïve. While treated with RTX, 62(72.9%) patients reached a free-of-relapse status, with statistically significant decrease in the mean ARR from 0.82 to 0.36 [0.14 (95%CI: 0.09-0.20), p = 0.0001 and EDSS [0.25 CI 0-0.5 (p = 0.034)] and a decrease in their T1 Gd-enhancing MRI lesions (1.64 vs. 0.12 CI 0.70-2.30, p = 0.004. 29 (29.4%) patients achieved NEDA-3. Among all patients, only 2 (2.4%) experienced infusion-related mild adverse events. No serious adverse events were reported. CONCLUSION: We found significant clinical and radiological improvement in naïve and non-naïve MS patients treated with RTX.

BACKGROUND: Multiple Sclerosis is the central nervous system's most common demyelinating disease and the second leading cause of neurological disability in young adults. Its natural development involves physical and cognitive impairment. Patients commonly perceive discrimination against them, regardless of its occurrence, accepting it as an inherent part of the disease. OBJECTIVE: This study aimed to determine the association between perceived discrimination and the depressive symptoms and physical disability present in patients diagnosed with multiple sclerosis, treated at the Demyelinating Diseases Clinic of the National Institute of Neurology and Neurosurgery, Manuel Velasco Suárez. METHODS: A cross-sectional study was conducted in 98 patients diagnosed with multiple sclerosis. Demographic and clinical variables were obtained through clinical interviews. The severity of the disease was determined using the Extended Disability Status Scale (EDSS), depressive symptoms were assessed with the Beck Depression Inventory (BDI), and perceived discrimination was rated using the King Internalized Stigma Scale. RESULTS: The studied sample's mean age was 36.3 years, schooling 13.6 years, symptoms onset was at 26.2 years (with a delay in diagnosis of 3.2 years), and a disease evolution of 10.9 years. 71.4% were single; 52% had an unpaid work activity and 57.1% were women. The EDSS average was 3.5 points; 24.5% presented moderate to severe depressive symptoms and 53.1% referred perceived discrimination. CONCLUSIONS: Perceived discrimination in patients with multiple sclerosis was associated with earlier disease onset, depressive symptoms, and the lack of caregivers. Medical care and life quality improvement for this vulnerable group require greater education regarding the disease and the establishment of patient support programs.

Métodos: Foram avaliados 40 pacientes com Esclerose Múltipla, usando Timed Up and Go, teste de Tinetti, teste de caminhada de 25 pés e escala de EDSS. Resultados: No presente estudo, observamos correlações moderadas a altas entre EDSS e Timed Up and Go, teste de Tinetti e teste de caminhada de 25 pés (p < 0,0001). Os pacientes relataram tempos de execução mais longos para os testes Timed Up and Go e 25-Foot Walk e menores escores no teste de Tinetti. Encontramos uma correlação direta entre a duração da doença, a escala EDSS, o tempo de execução Timed Up and Go, o tempo de execução de 25-Foot Walk e o escore do teste de Tinetti (p < 0,0001). Conclusão: avaliações adequadas de risco de marcha e queda são importantes para evitar complicações relacionadas à Esclerose Múltipla. (AU)
Objective: To demonstrate correlation functional evaluations of gait on the patients with Multiple sclerosis, using a noninvasive method by means of Timed Up and Go, Tinetti test, 25-Foot Walk test and Expanded Disability Status Scale (EDSS). Methods: We evaluated 40 patients with Multiple sclerosis using Timed Up and Go, Tinetti test, 25-Foot Walk test and EDSS scale. Results: In present study, we have observed moderate to high correlations between EDSS and Timed Up and Go, Tinetti test and 25-Foot Walk test (p<0.0001). The patients reported longer execution times for Timed Up and Go and 25-Foot Walk tests and lower scores on the Tinetti test. We found a direct correlation between illness duration, EDSS scale, Timed Up and Go execution time, 25-Foot Walk execution time and Tinetti test score (p<0.0001). Conclusion: Proper gait and fall risk evaluations are important in order to avoid complications that are related to Multiple sclerosis. (AU)

The aim of this study was to assess vitamin D status in patients with multiple sclerosis (MS) and to evaluate whether it was associated with oxidative and nitrosative stress (O&NS) markers and disability. This study included 137 patients with MS and 218 healthy controls. The markers evaluated were serum levels of 25-hydroxyvitamin D, lipid hydroperoxides, advanced oxidation protein products (AOPP), nitric oxide metabolites (NOx), and total radical-trapping antioxidant parameter TRAP/UA. Patients with 25(OH)D<20ng/mL showed higher EDSS (p=0.016), MSSS (p=0.005) and lower AOPP (p=0.046) than those with 25(OH)D≥20ng/mL. After the binary logistic regression analyses, EDSS and MSSS remained significantly associated with vitamin D deficiency. We showed that lower levels of 25(OH)D were associated with higher EDSS and MSSS independently of variables such as O&NS, age, sex, body mass index, ethnicity, MS therapy, use of interferon beta, and clinical forms of MS (odds ratio: 1.380, 95% confidence interval 1.030-1.843, p=0.031). Moreover, the study showed an association between serum levels of 25(OH)D and EDSS (r2=0.115, p=0.002), demonstrating that 25(OH)D may contribute with 11.5% of increase in EDSS. Our results suggest that vitamin D deficiency may be considered one of the predictors of the disability in MS patients, independently of their redox status and influence the progression of disability in MS.

Wastewater treatment selection is a complex task usually addressed by applying separate tools for the correct assessment of multi-criteria evaluation. Novedar_EDSS integrates technical, environmental, economic and social assessment capabilities in one single platform. The aim of this work is to evaluate and demonstrate the capabilities of this environmental decision support system (EDSS). For that purpose, 4 case studies of real projects were selected to validate the results in the EDSS by comparing them with those from the study of alternatives performed by the decision makers. Moreover, 1 conceptual case study was applied to support the selection of the most properly strategy for plant retrofitting. Results have demonstrated that the EDSS provides key aspects when deciding the retrofitting process to apply and, when compared to real projects, it recommends analogue treatments as those applied in the projects, ranking them in the same order. Therefore, results in the validation process performed show that this tool provides a reliable basis to support decision makers to select properly treatment alternatives in wastewater treatment plant pre-design.

OBJECTIVE: The aims of the present study were to report the prevalence of insulin resistance (IR) in patients with multiple sclerosis (MS); to verify differences in metabolic and inflammatory biomarkers, and oxidative stress in patients with MS with or without IR; and to assess if IR and adiposity are associated with disability in these patients. METHODS: The study enrolled 110 patients with MS and 175 healthy individuals. Patients with MS were divided in those with IR (n = 44) and those without (n = 66). Metabolic and inflammatory markers, oxidative stress, and disability were evaluated by the Extended Disability Status Scale (EDSS). RESULTS: IR prevalence was verified in 40% of the patients with MS and in 21.1% of the control group (odds ratio, 2.48; 95% confidence interval, 1.469-4.210; P = 0.0006). Patients with the disease and IR showed higher EDSS (P = 0.031), interleukin (IL)-6 (P = 0.028), IL-17 (P = 0.006), oxidative stress evaluated by tert-butyl hydroperoxide-initiated chemiluminescence (P = 0.029), and advanced oxidation protein products (P = 0.025) than those patients without IR. The multivariate analysis showed that disability was associated with IR evaluated by homeostasis model assessment of insulin resistance (P = 0.030) and adiposity evaluated by waist circumference (P = 0.0179) and body mass index (P = 0.0033). CONCLUSION: This is the first study to demonstrate an increase IR prevalence and the association between IR and adiposity with disability assessed by EDSS in patients with MS. IR seems to be associated with chronic inflammatory process and oxidative stress in patients with MS. More studies are warranted to elucidate the mechanisms by which IR and adiposity could contribute to the progression and disability in patients with MS.

The efficacies of immunosuppressive (IMS) and immunomodulatory (IMM) drugs for multiple sclerosis (MS) have been reported in several studies. These agents can reduce relapse rates and lesions observed by magnetic resonance imaging studies. However, the effect of these medications in disability progression over 4 years is rarely examined. OBJECTIVE: To study the disabilities associated with MS patients after a long time period and to analyze the therapeutic influence of different types of treatments in patient disease progression. METHOD: This is an open, uncontrolled, non-randomized, retrospective study of the disease progression using the Expanded Disability Status Scale (EDSS) and the Multiple Sclerosis Severity Score (MSSS) in 155 cases of MS, which were 76 percent female with a mean age of onset of 30.21±9.70. The follow-up period was 115.39±88.08 months (median 92, 3 to 447 months). These cases were submitted to the following 277 different therapeutic procedures: 62 without IMS or IMM therapy (SYT) (just corticosteroids), 53 with azathioprine (AZA), 53 interferon-β (IFNβ)-1b 250 µg (BET), 55 IFNβ-1a 22 µg (R22), 19 IFNβ-1a 30 µg (AVO), 15 IFNβ-1a 44 µg (R44), 15 glatiramer acetate (COP) 20 mg, and 5 cases with mitoxantrone (MIT). RESULTS: The median EDSS group was 2.00 (0 to 5.5, mean 1.89±1.52) at the onset of each treatment and 2.50 (0 to 9, mean 3.06±2.18) at the end. The median initial MSSS was 3.34 (0.25 to 9.50, mean 3.94±2.91) and the final medial was 3.90 (0.05 to 9.88, mean 4.02±2.78). The EDSS between initial and final score for the whole group had statistically significant progression, as well as for the sub-groups SYT, AZA, BET and R22. No statistically significance difference was found in the MSSS between initial and final scores in the whole group or treatment sub-groups. The variation between the initial and final EDSS and MSSS among the types of treatments found no statistical significance...
A eficácia das medicações imunossupressivas (IMS) e imunomoduladoras (IMM) na esclerose múltipla (MS) tem sido relatada em diversos estudos. Essas medicações podem reduzir o número de surtos e de lesões observadas nos estudos de ressonância magnética. Entretanto, o efeito dessas medicações na progressão da incapacidade em período acima de quatro anos é raramente estudado. OBJETIVO: Estudar a incapacidade associada à MS em longo prazo e analisar os benefícios dos diferentes tipos de tratamento na progressão da doença. MÉTODO: Estudo aberto e retrospectivo da progressão da incapacidade utilizando a escala expandida do grau de incapacidade (EDSS) e o escore da gravidade da esclerose múltipla (MSSS) em 155 casos de MS, sendo 76 por cento do sexo feminino, idade média no início da doença 30,21±9,70 anos e período médio de seguimento 115,39±77,08, mediana 92 (3 a 447) meses. Os casos foram submetidos a 277 tipos diferentes de tratamentos: 62 casos não usaram IMS ou IMM, somente corticosteróides (SYT); 53 com azatioprina (AZA); 53 com interferon-β (IFNβ)-1b 250 µg (BET); 55 com IFNβ-1a 22 µg (R22); 19 com IFNβ-1a 30 µg (AVO); 15 com IFNβ-1a 44 µg (R44); 15 com acetato de glatiramer (COP) 20 mg, e 5 casos com mitoxantrone (MIT). RESULTADOS: A mediana do EDSS do grupo foi 2,0 (0 a 5,5, média total do grupo foi 1,89±1,52) no início de cada tratamento e 2,50 (0 a 9, média de 3,06±2,18) no fim. A mediana inicial da MSSS foi 3,34 (0,25 a 9,50, média 3,94±2,91) e a final 3,90 (0,05 a 9,88, média 4,02±2,78). O EDSS entre o início e o fim do tratamento do grupo mostrou progressão estatisticamente significante e também para os subgrupos SYT, AZA, BET e R22. Não foi encontrada diferença estatística no MSSS entre o início e fim do tratamento no grupo total ou nos subgrupos. Não foi encontrada diferença estatisticamente significante entre a variação inicial e final do EDSS e MSSS entre os diversos subgrupos de tratamento...

The Guy's neurological disability scale (GNDS) has recently been introduced as a new measure of disability in multiple sclerosis. It is patient-oriented, multidimensional, and not biased towards any particular disability. The purpose of the present study was to validate the Brazilian version of the GNDS. The adaptation of the scale was based on the translation/back-translation methodology. Sixty-two patients with clinically definite multiple sclerosis (CDMS) according to Poser's criteria were recruited for this study. GNDS was administered individually to each subject. The EDSS and the ambulation index (AI) scores were assigned by a neurologist. The intraclass correlation coefficient and the Cronbach's alpha values of the Brazilian version of GNDS (0.94 and 0.83, respectively) were comparable to the original one (0.98 and 0.79, respectively). Furthermore, the factor analysis of the Brazilian version of GNDS suggested, as the original article, a four-factor solution which accounted for 68.8 percent of the total variance. The Brazilian version of GNDS was found to be clinically relevant as it correlated significantly with the EDSS and AI. In conclusion, the Brazilian version of GNDS can be considered an important tool to evaluate the disability in MS patients, with clinical usefulness and psychometrics soundness.
A Guy's neurological disability scale (GNDS) é uma escala de incapacidade criada recentemente, orientada para o paciente, multidimensional, e que não privilegia nenhum tipo específico de incapacidade. O objetivo deste estudo é validar a GNDS para a língua portuguesa. A adaptação da escala foi feita através do método de tradução e re-tradução. Sessenta e dois pacientes com esclerose múltipla (EM) clinicamente definida de acordo com os critérios de Poser participaram deste estudo. A GNDS foi aplicada individualmente em cada paciente. O EDSS e o índice ambulatorial (IA) foram determinados por neurologista. A correlação intra-classe e o valor de Cronbach's alfa da versão brasileira da GNDS (0.94 e 0.83, respectivamente) foram comparáveis aos do artigo original (0.98 e 0.79, respectivamente). Como no artigo original, a análise fatorial da versão brasileira da GNDS sugeriu uma solução de quatro fatores que explicaria 68.8 por cento da variação total. A versão brasileira da GNDS mostrou-se clinicamente relevante uma vez que se correlacionou com o EDSS e o IA. Em conclusão, a versão brasileira da GNDS pode ser considerada como um importante instrumento de avaliação incapacidade na EM com significado clínico e relevância psicométrica.
