Coexistence of restless legs syndrome and multiple sclerosis aggravates anxiety and depression.

BACKGROUND: Among the comorbidities that accompany multiple sclerosis (MS), restless legs syndrome (RLS) is one of the most common. Anxiety and depression are common psychological comorbidities that impact the quality of life of patients with MS (PwMS), as well as patients with RLS. OBJECTIVE: To investigate the psychiatric burden of MS and RLS coexistence, we conducted a nationwide, multicenter and cross-sectional survey. METHODS: Participants were assessed by using demographic and clinical parameters along with the Hamilton Anxiety and Hamilton Depression Scales (HAM-A and HAM-D). RESULTS: Out of the 1,068 participants, 173 (16.2%) were found to have RLS [RLS(+)] and 895 (83.8%) did not [RLS(-)]. The mean scores for HAM-A and HAM-D were significantly higher among RLS(+) subjects than among RLS(-) subjects (p<0.001 for all variables). CONCLUSIONS: According to our data, the presence of RLS in PwMS may increase the occurrence of both anxiety and depression symptoms. Awareness and treatment of RLS in PwMS could possibly reduce the symptoms of psychiatric comorbidities originating from RLS.

RESUMO Antecedentes: Considerando-se as comorbidades que acompanham a esclerose múltipla (EM), a síndrome das pernas inquietas (SPI) é uma das mais comuns, e ansiedade e depressão são comorbidades psicológicas comuns que afetam a qualidade de vida de pacientes com EM, bem como de pacientes com SPI. Objetivo: Investigar a carga psiquiátrica da coexistência de EM e SPI por meio de uma pesquisa nacional, multicêntrica e transversal. Métodos: Os participantes foram avaliados por parâmetros demográficos e clínicos, além da versão turca das escalas de ansiedade e depressão de Hamilton (HAM-A e HAM-D). Resultados: Dos 1.068 participantes, 173 (16,2%) apresentaram SPI [SPI (+)] e 895 (83,8%) não [SPI (-)]. As pontuações médias no HAM-A e no HAM-D foram significativamente maiores em indivíduos com SPI (+) do que naqueles com SPI (-) (p <0,001 para todas as variáveis). Conclusões: De acordo com nossos dados, a presença de SPI na EM pode aumentar a ocorrência de sintomas de ansiedade e depressão. A conscientização e o tratamento da SPI na EM podem reduzir os sintomas de comorbidades psiquiátricas originadas da SPI.

Optical coherence tomography angiography (OCTA) in differential diagnosis of aquaporin-4 antibody seronegative NMOSD and multiple sclerosis.

BACKROUND: Optic neuritis(ON) is a common feature of both relapsing-remitting multiple sclerosis(RRMS) and neuromyelitis optica spectrum disorders(NMOSD). It is crucial to early differentiate these two diseases, as they differ in pathophysiology and treatment. OBJECTIVE: To compare NMOSD and RRMS patients using optical coherence tomography(OCT) and OCT angiography(OCTA) to assess retinal microvascular network differences. METHODS: Fourteen RRMS (28 eyes) and 9 NMOSD patients(18 eyes), and 11 controls were enrolled. Seropositivity for aquaporin-4 antibody (anti-AQP4 Abs) was 44.4%. Peripapillary and macular retinal nerve fiber layer(RNFL) thickness, superficial peripapillary and macular vessel density(VD), area, perimeter and circularity of foveal avascular zone(FAZ) were analyzed. RESULTS: OCTA showed reduction in peripapillary and macular VD and FAZ size in NMOSD+ON compared to RRMS+ON and controls (p = 0.001, p<0.001 and p = 0.010, p<0.001 respectively). Peripapillary VD was similar in RRMS +ON and controls. Peripapillary VD in monophasic seronegative NMOSD+ON eyes was significantly lower than monophasic RRMS+ON eyes (p = 0.030), which was no different from controls. FAZ area was smaller in unaffected eyes in NMOSD than RRMS and controls. CONCLUSIONS: Both OCT and OCTA revealed considerable differences between RRMS and NMOSD patients, providing promising results in favor of clinical utility of OCTA in differential diagnosis of ON, particularly in anti-AQP4 antibody negative patients. OCTA might be a useful biomarker in differentiating NMOSD from MS.

Safe and successful use of oocyte in-vitro maturation in two infertile women with multiple sclerosis.

There is evidence to support an impact of ovarian stimulation with gonadotrophin-releasing hormone analogues on the progression or recurrence of multiple sclerosis. In addition, there is no universally acknowledged approach toward ovarian stimulation in patients with multiple sclerosis. This report describes two patients at a large tertiary university hospital who underwent an in-vitro maturation protocol in order to avoid a risk of exacerbating their multiple sclerosis by ovarian stimulation. Both patients were referred to the infertility clinic because of the concern of exacerbation of multiple sclerosis during or after ovarian stimulation treatment. The patients underwent the in-vitro maturation protocol to avoid ovarian stimulating agents. Both patients gave birth to healthy babies at term. They did not suffer any relapses of multiple sclerosis during their treatment or during pregnancy. Exacerbation of disease related to ovarian stimulation encourages the search for a safer approach to these patients. To the authors' knowledge, these are the first babies described in the literature who were born after in-vitro maturation to mothers suffering from multiple sclerosis. In-vitro maturation can thus be recommended as an alternative in suitable women with multiple sclerosis.

Effects of aquatic exercises on postural control and hand function in Multiple Sclerosis: Halliwick versus Aquatic Plyometric Exercises: a randomised trial.

OBJECTIVES: Postural control and hand dexterity are significantly impaired in people with multiple sclerosis (pwMS). Aquatic interventions may have additional benefits in the treatment of pwMS. The purpose of this study is to compare the effects of two different aquatic exercises on postural control and hand function. METHODS: Thirty pwMS, relapsing-remitting type were randomly divided into a Halliwick (Hallw) and an Aquatic Plyometric Exercise (APE) group. The Limits of Stability test was used to evaluate postural control using the Biodex Balance System. The Nine-Hole Peg Test was used to evaluate hand dexterity. Both exercise interventions were performed twice a week for 8 weeks, in a pool with a depth of 120 cm and water temperature of 30-31°C. RESULTS: Limits of stability improved significantly in both groups (p<0.05) and Hallw group completed the test in a significantly shorter time (p<0.05). Hand dexterity improved significantly in both groups (p<0.01). Following intergroup analysis, Hallw group showed significantly higher improvement in hand dexterity and overall limits of stability test score (p<0.05). CONCLUSIONS: This study provides evidence that both Halliwick and APE are effective to treat balance and hand dexterity. This paper is the first evidence on APE for pwMS and showed that it is safe and improved trunk control and hand dexterity.

'Is RLS a harbinger and consequence of MS?: Striking results of the 'RELOMS-T' study'.

BACKGROUND: Although studies report a high prevalence rate of restless legs syndrome (RLS) among patients with multiple sclerosis (PwMS) ranging from 13.3 to 65.1%, little is known about the causes of this relationship. METHODS: To ascertain the prevalence, features and impact of RLS among PwMS a nation-wide, multicenter, prospective and a cross-sectional survey, designed to reflect all of the PwMS throughout Turkey, was conducted in 13 centers. Exploring the relationship of the two conditions could possibly contribute to the understanding of the causes of the high and wide-ranging prevalence rates and the pathophysiology of both diseases. RESULTS: Of the 1068 participants 173 (16,2%) found to have RLS [RLS(+)] and 895 (83,8%) did not [RLS(-)]. Among the RLS(+) 173, all but 8 patients (4,6%) were underdiagnosed in terms of RLS. More than half of the patients with RLS had 'severe' or 'very severe' RLS. The onset of RLS was before or synchronous with the onset of MS in about a half of our patients. CONCLUSION: We conclude that RLS should be meticulously investigated in PwMS and MS can be a direct cause of RLS at least in part of PwMS. Our data about the timing of the onset of MS and RLS, along with the high prevalence of RLS in PwMS suggest that the pathologic changes in the initial phases of MS can possibly trigger RLS symptoms.

Physical, cognitive and psychosocial effects of telerehabilitation-based motor imagery training in people with multiple sclerosis: A randomized controlled pilot trial.

INTRODUCTION: Motor imagery training delivered at home via telerehabilitation is a novel rehabilitation concept. The aim was to investigate the effects of telerehabilitation-based motor imaging training (Tele-MIT) on gait, balance and cognitive and psychosocial outcomes in people with multiple sclerosis (pwMS). METHODS: This randomized, controlled pilot trial included pwMS and healthy individuals. pwMS were randomly divided into two groups, intervention and control. The intervention group received Tele-MIT twice a week for 8 weeks. The control group was a wait-list group without any additional specific treatment. Healthy participants served as a baseline comparison. The Dynamic Gait Index, used to assess dynamic balance during walking, was the primary outcome. Secondary outcomes included assessments of walking speed, endurance and perceived ability, balance performance assessed by a computerized posturography device, balance confidence, cognitive functions, fatigue, anxiety, depression and quality of life. RESULTS: Baseline comparisons with healthy individuals revealed that motor imagery abilities were preserved in pwMS (p > 0.05). The intervention group exhibited significant improvements in dynamic balance during walking (p = 0.002), walking speed (p = 0.007), perceived walking ability (p = 0.008), balance confidence (p = 0.002), most cognitive functions (p = 0.001-0.008), fatigue (p = 0.001), anxiety (p = 0.001), depression (p = 0.005) and quality of life (p = 0.002). No significant changes were observed in the control group in any of the outcome measures (p > 0.05). DISCUSSION: Tele-MIT is a novel method that proved feasible and effective in improving dynamic balance during walking, walking speed and perceived walking ability, balance confidence, cognitive functions, fatigue, anxiety, depression and quality of life in pwMS.

Anti-N-methyl-d-aspartate receptor encephalitis during pregnancy: A case report.

Following a generalized tonic-clonic seizure, a previously healthy 27-year-old pregnant woman (18-week pregnancy) was admitted to our emergency department. She experienced lethargy, forgetfulness and persecutory hallucinations the day before hospitalization. Cerebrospinal fluid examination revealed moderate pleocytosis, and abdominal ultrasonography did not detect neoplasia. Orofacial dyskinesia, catatonia and central hypoventilation gradually developed despite medical intervention to ameliorate the symptoms. At 32 weeks of pregnancy, vaginal bleeding and hypotension occurred. Further, owing to septic shock due to fetal demise, the patient died. N-methyl-d-aspartate antibody test results obtained after the patient's death were positive (2++). Currently, no consensus exists on the appropriate treatment and follow-up for pregnant women with anti-N-methyl-d-aspartate receptor encephalitis; however, immunomodulators and teratoma resection may be helpful. Second line immunotherapy (rituximab, cyclophosphamide) and teratoma resection may be necessary in pregnant patients with high N-methyl-d-aspartate receptor antibody titers and inadequate response to first-line treatment.

A Novel Biomarker in Diabetic Macular Edema with Serous Retinal Detachment: Serum Chitinase-3-Like Protein 1.

PURPOSE: To determine whether serum chitinase-3-like protein 1 (CHI3L1) and interleukin-6 (IL-6) levels correlate with serous retinal detachment (SRD) in diabetic macular edema (DME) using spectral-domain optical coherence tomography (SD-OCT). METHODS: In this cross-sectional case-control study, 394 patients (treatment-naive DME patients, n = 218; diabetic patients without DME, n = 96; nondiabetic controls, n = 80) were included in the study. Eyes were classified according to SD-OCT features of DME: SRD, cystoid macular edema (CMO), and diffuse retinal thickness (DRT). Serum concentrations of CHI3L1 and IL-6 were analyzed using enzyme-linked immunosorbent assay. RESULTS: Serum CHI3L1 and IL-6 levels were significantly higher in DME with SRD compared to patients with CMO and DRT (p < 0.001 for all groups). Multivariate regression analysis showed that CHI3L1 and IL-6 had a stronger influence on the presence of SRD in DME (r = 1.162, p = 0.026, and r = 1.242, p = 0.016, respectively). Serum concentration of CHI3L1 was significantly correlated with that of IL-6 (r = 0.386, p = 0.0015). CONCLUSIONS: Our data suggest that serum concentrations of CHI3L1 and IL-6 are involved in the process of SRD in DME. CHI3L1 can be investigated further as a new diagnostic biomarker for DME with SRD.

Do coping styles mediate the relationship between disability status and psychosocial loss in people with relapsing remitting multiple sclerosis?

The main aim of this cross-sectional study was to analyse the degree to which coping may act as a mediator between disability and psychosocial loss in people with relapsing remitting multiple sclerosis. Participants ( N = 158) completed measures of psychosocial loss and ways of coping. Disability status was evaluated by attending neurologists. Coping partially mediated the relationship between disability and psychosocial loss. Disability leads to the experience of psychosocial loss but it is not the sole factor determining the formation of psychosocial loss. Coping is also associated with such losses in multiple sclerosis.

Different types of exercise in Multiple Sclerosis: Aerobic exercise or Pilates, a single-blind clinical study.

BACKROUND: The aim of our study is to examine effects of aerobic and Pilates exercises on disability, cognition, physical performance, balance, depression and fatigue in relapsing-remitting Multiple Sclerosis (MS) patients as compared to healthy controls. METHODS: The subjects were divided as aerobic exercise (n = 26), Pilates (n = 9), and the healthy control group (n = 21). We used MSFC, physical performance, Berg balance scale, Beck depression scale, fatigue impact scale. All evaluations were performed before and after exercise training. RESULTS: There are statistically meaningful differences between Nine hole testing, PASAT 3, physical performance and fatique impact scale before and after aerobic exercise. Also we found significant difference for physical performance in the Pilates group. There are no significant differences in measures of fatique impact scale and depression between aerobic exercise group and the healthy controls after exercise. We found significant differences between Pilates and control group's after measurements except depression. There were significant differences between the Pilates and aerobic group for cognitive tests in favor of the Pilates group. CONCLUSION: Aerobic exercise and clinical Pilates exercises revealed moderate changes in levels of cognitive, physical performance, balance, depression, fatigue in MS patients.

Effects of Pilates exercises on sensory interaction, postural control and fatigue in patients with multiple sclerosis.

BACKGROUND: Decreased postural control, sensory integration deficits and fatigue are important problems that cause functional impairments in patients with multiple sclerosis (pwMS). PURPOSE: To examine the effect of modified clinical Pilates exercises on sensory interaction and balance, postural control and fatigue in pwMS. METHODS: Eleven patients with multiple sclerosis and 12 healthy matched controls were recruited in this study. Limits of stability and postural stability tests were used to evaluate postural control by Biodex Balance System and sensory interaction assessed. Fatigue was assessed by Modified Fatigue Impact Scale. Pilates exercises were applied two times a week for 10 weeks and measurements were repeated to pwMS after exercise training. RESULTS: Postural control and fatigue (except psychosocial parameter) of pwMS were significantly worser than healthy controls (p<0.05). Significant improvements occurred in sensory interaction (eyes open, foam surface) and total, physical and cognitive scores of fatigue after 10-week modified clinical Pilates training (p<0.05). No significant changes were detected in postural control after the pilates exercises (p>0.05). CONCLUSIONS: Ten-week Pilates training is effective to improve sensory interaction and to decrease fatigue. Pilates exercises can be applied safely in ambulatory pwMS for enhance sensory interaction and balance and combat fatigue. More investigations are needed.

Improvements in cognition, quality of life, and physical performance with clinical Pilates in multiple sclerosis: a randomized controlled trial.

[Purpose] The aim of this study was to determine the effects of clinical Pilates in multiple sclerosis patients. [Subjects and Methods] Twenty multiple sclerosis patients were enrolled in this study. The participants were divided into two groups as the clinical Pilates and control groups. Cognition (Multiple Sclerosis Functional Composite), balance (Berg Balance Scale), physical performance (timed performance tests, Timed up and go test), tiredness (Modified Fatigue Impact scale), depression (Beck Depression Inventory), and quality of life (Multiple Sclerosis International Quality of Life Questionnaire) were measured before and after treatment in all participants. [Results] There were statistically significant differences in balance, timed performance, tiredness and Multiple Sclerosis Functional Composite tests between before and after treatment in the clinical Pilates group. We also found significant differences in timed performance tests, the Timed up and go test and the Multiple Sclerosis Functional Composite between before and after treatment in the control group. According to the difference analyses, there were significant differences in Multiple Sclerosis Functional Composite and Multiple Sclerosis International Quality of Life Questionnaire scores between the two groups in favor of the clinical Pilates group. There were statistically significant clinical differences in favor of the clinical Pilates group in comparison of measurements between the groups. Clinical Pilates improved cognitive functions and quality of life compared with traditional exercise. [Conclusion] In Multiple Sclerosis treatment, clinical Pilates should be used as a holistic approach by physical therapists.

Utilization of the Expanded Disability Status Scale as a distinctive instrument for walking impairment in persons with multiple sclerosis with mild disability.

BACKGROUND: The Expanded Disability Status Scale (EDSS) is a well-established clinical measure to assess disability in multiple sclerosis (MS). Gait dysfunction is primarily considered for scoring only above EDSS 3.5. However, the changes in functional systems in below EDSS 3.5 may result gait disturbances. OBJECTIVE: To determine the distinctive ability of the EDSS 2.0 in terms of walking impairment as well as fatigue, depression, and quality of life in persons with MS with mild disability. METHODS: All participants underwent the neurological examination for generating an EDSS score and completed the measures of walking performance, as well as other measures of fatigue, depression, and quality of life. The participants were divided into two groups according to the EDSS scores (i.e. EDSS <2.0 and 2.0-3.5). RESULTS: Participants with EDSS 2.0-3.5 had significantly worse walking performance, as well as fatigue, depression, and quality of life levels than the participants with EDSS <2.0 (p <  0.05). The EDSS significantly correlated with the measures of walking performance, as well as other measures of fatigue, depression, and quality of life. CONCLUSIONS: The EDSS 2.0 has a distinctive ability in terms of walking impairment as well as fatigue, depression, and quality of life.

Determinants of physical activity in minimally impaired people with multiple sclerosis.

OBJECTIVE: Despite the commonly known benefits of physical activity, evidence shows that people with multiple sclerosis (pwMS) are relatively inactive. There are several studies about factors affecting physical activity in pwMS. However, these factors have not investigated in minimally impaired pwMS who do not have remarkable symptoms and walking disturbance. The objective was to determine factors affecting physical activity in minimally impaired pwMS. PATIENTS AND METHODS: We recruited 52 minimally impaired pwMS and measured physical activity with Godin Leisure-Time Exercise Questionnaire (GLTEQ) and an accelerometer used for the 7-day period. Demographic data were recorded. Walking (speed, endurance, dexterity, and quality), fatigue, depression, and quality of life were measured. METHODS: We recruited 52 minimally impaired pwMS and measured physical activity with Godin Leisure-Time Exercise Questionnaire (GLTEQ) and an accelerometer used for the 7-day period. Demographic data were recorded. Walking (speed, endurance, dexterity, and quality), fatigue, depression, and quality of life were measured. RESULTS: The walking speed assessed by the Timed 25-Foot Walk and gender were found the determinants of physical activity level assessed by the GLTEQ and accelerometer, respectively. Walking (speed, endurance, and dexterity), gender, employment status, and quality of life were associated with physical activity. Either female or unemployed participants had significantly less physical activity. There were no significant difference between physical activity levels and the other subgroups. CONCLUSION: Either to be a female or to have slower walking speed was associated with less physical activity. Strategies to improve walking should be focused on female pwMS with minimal impairment.

Tau protein levels in the cerebrospinal fluid of the patients with multiple sclerosis in an attack period: Low levels of tau protein may have significance, too.

OBJECTIVES: Axonal loss is the cause of permanent neurologic disability in patients with MS. There are a lot of candidates to be a surrogate biological marker of the axonal loss in MS including tau protein. In the present study, we aimed to assess the levels of the tau protein in patients with MS, and in neurologically healthy controls. PATIENTS AND METHODS: We included 41 patients with MS (32 RRMS, 9 SPMS) in this study. All the patients with MS were in an attack period. Control group was consist of 18 neurologically healty patients who underwent spinal anesthesia for orthopedic operations. The CSF tau protein level was measured by double antibody sandwich ELISA. RESULTS: The patients with RRMS had a higher tau protein level than the patients with SPMS and the control group. The patients with SPMS had a lower tau protein level than the control group. CONCLUSION: High levels of tau protein in the CSF of RRMS patients in an attack period may indicate ongoing axonal transection owing to inflammation. Due to the brain atrophy, the patients with SPMS have less neurons to produce tau protein. The low levels of tau protein in the CSF of SPMS patients may denote axonal degeneration.

Uveitis associated with multiple sclerosis: complications and visual prognosis.

AIM: To determine the frequency, subtype, complications, treatment and visual prognosis of uveitis in patients with multiple sclerosis (MS). METHODS: A total of 1702 MS patients' medical records were reviewed for a history of uveitis both with a neurologist and an ophthalmologist. RESULTS: Nine patients (0.52%) with uveitis were detected. Eight of them were female, one was male. The mean age was 42.0±14.1y (range 22-66). Seven patients were relapsing remitting MS, two were secondary progressive MS. The mean duration of MS was 10.8±10.3y, and the mean duration of uveitis 10.3±9.9y. The onset of uveitis preceded that of MS (four patients) by a mean of 5.0±4.3y (range 1-11). MS diagnosed prior to the onset of uveitis (five patients) by an interval of 0.75-16y (mean 4.95±6.24y). There were 16 affected eyes of nine patients. The most common types of uveitis were panuveitis and intermediate uveitis. Uveitis was bilateral in most patients. The most common complications were cataract and glaucoma, and patients with such complications were surgically treated. The range of visual acuity of affected eyes was 20/800 to 20/22, with only six of 16 affected eyes better than 20/40. After treatment, the visual acuity of the affected eyes was better than 20/40 in 11 of 16 eyes. CONCLUSION: Uveitis should be considered when assessing an MS patient with visual loss, as surgical interventions other than medical treatments may be needed to improve visual function. Complications could be seen more often when posterior segment is involved.

Contingent negative variation is associated with cognitive dysfunction and secondary progressive disease course in multiple sclerosis.

BACKGROUND AND PURPOSE: The relationship between contingent negative variation (CNV), which is an event-related potential, and cognition in multiple sclerosis (MS) has not been examined previously. The primary objective of the present study was thus to determine the association between CNV and cognition in a sample of MS patients. METHODS: The subjects of this study comprised 66 MS patients [50 with relapsing-remitting MS (RRMS) and 16 with secondary progressive MS (SPMS)] and 40 matched healthy volunteers. A neuropsychological battery was administered to all of the subjects; CNV recordings were made from the Cz, Fz, and Pz electrodes, and the amplitude and area under the curve (AUC) were measured at each electrode. RESULTS: RRMS patients exhibited CNVs with lower amplitudes and smaller AUCs than the controls at Pz. SPMS patients exhibited CNVs with lower amplitudes and smaller AUCs than the controls, and CNVs with a smaller amplitude than the RRMS patients at both Cz and Pz. After correcting for multiple comparisons, a lower CNV amplitude at Pz was significantly associated with worse performance on measures of speed of information processing, verbal fluency, verbal learning, and verbal recall. CONCLUSIONS: CNV may serve as a marker for disease progression and cognitive dysfunction in MS. Further studies with larger samples and wider electrode coverage are required to fully assess the value of CNV in these areas.

Caregiver burden, quality of life and walking ability in different disability levels of multiple sclerosis.

BACKGROUND: The caregivers of Multiple Sclerosis (MS) individuals are usually burdened with a wide range of MS-related caregiving tasks which may result in damages of their daily life and quality of life (QOL). OBJECTIVES: This study was designed to compare according to the disability level (1) the walking ability, quality of life (QOL), and disease impact of the MS patients (2) and the burden, QOL, self-efficacy and life satisfaction of their caregivers; (3) to determine the relationship between these outcome results, disease duration and caregivers' age. METHODS: 772 MS patients were recruited, 47 MS patients and their 47 caregivers finished the study. Disability, walking ability, QOL, disease impact of the MS participants; the burden, QOL, self-efficacy, life satisfaction of the caregivers were evaluated. RESULTS: MS Patients with higher disability had significantly worse scores on the MSWS-12, MUSIQOL, MSIS-29, and PDSS (p < 0.01). The caregivers facing with higher disability had significantly worse scores on CBI and CAREQOL (p < 0.01). CONCLUSIONS: The impairments on disability level, walking and QOL of MS patients were related to OQL declines and increased burden of their caregivers. Therefore, it may be important to provide acceptable education and support strategies with individual intervention while defining the needs and goals of the MS patients and their caregivers to improve the rehabilitation success.
