Conversion to secondary progressive multiple sclerosis: Multistakeholder experiences and needs in Italy.

BACKGROUND: Conversion to secondary progressive multiple sclerosis (SPMS) is associated with a relatively poor prognosis, and SPMS is responsible for the majority of the social and economic costs associated with MS. Managing the Transition to SPMS (ManTra) is a mixed methods project conducted in Italy and Germany aimed to set up a user-led resource to empower and improve the quality of life of newly diagnosed SPMS patients. AIMS: To assess the experiences and the needs of Italian people who recently converted to SPMS, patient significant others (SOs), neurologists and other health professionals (HPs). METHODS: We conducted 15 personal semistructured interviews (PSIs) with SPMS patients who transitioned up to five years, and three focus group meetings (FGMs), one of SPMS SOs, one of neurologists, and one of other HPs. Participants were purposely selected from the three geographic areas of Italy, and varied in terms of gender, education and (for patients) disease severity. PSIs and FGMs were audiorecorded, transcribed and analyzed by two researchers using the framework analysis. RESULTS: One hundred sub-categories were identified, grouped into 13 categories and four themes: 'awareness of the transition', 'communication of the transition', 'dealing with symptoms worsening', and 'needs'. The major unmet needs were collected in four dimensions 'organization and management; 'empowerment training'; 'information'; and 'policies'. CONCLUSIONS: Two are the main findings: first, the widespread lack of awareness around the transition; second, the need to improve the quality of the care pathway in the Italian context. It was particularly stressed the need for a holistic and multidisciplinary approach (with patients and SOs as members of the team), the development of an ad hoc plan of follow up visits with easy access to MS specialists' consultation/treatment; specialized training for each stakeholders; more information on SPMS, daily management and changes at policy level.

The Impact of Coconut Oil and Epigallocatechin Gallate on the Levels of IL-6, Anxiety and Disability in Multiple Sclerosis Patients.

BACKGROUND: Due to the inflammatory nature of multiple sclerosis (MS), interleukin 6 (IL-6) is high in blood levels, and it also increases the levels of anxiety related to functional disability. Epigallocatechin gallate (EGCG) decreases IL-6, which could be enhanced by the anti-inflammatory effect of high ketone bodies after administering coconut oil (both of which are an anxiolytic). Therefore, the aim of this study was to assess the impact of coconut oil and EGCG on the levels of IL-6, anxiety and functional disability in patients with MS. METHODS: A pilot study was conducted for four months with 51 MS patients who were randomly divided into an intervention group and a control group. The intervention group received 800 mg of EGCG and 60 mL of coconut oil, and the control group was prescribed a placebo. Both groups followed the same isocaloric Mediterranean diet. State and trait anxiety were determined before and after the study by means of the State-Trait Anxiety Inventory (STAI). In addition, IL-6 in serum was measured using the ELISA technique and functional capacity was determined with the Expanded Disability Status Scale (EDSS) and the body mass index (BMI). RESULTS: State anxiety and functional capacity decreased in the intervention group and IL-6 decreased in both groups. CONCLUSIONS: EGCG and coconut oil improve state anxiety and functional capacity. In addition, a decrease in IL-6 is observed in patients with MS, possibly due to the antioxidant capacity of the Mediterranean diet and its impact on improving BMI.

Looking into cognitive impairment in primary-progressive multiple sclerosis.

BACKGROUND AND PURPOSE: Cognitive impairment in primary-progressive multiple sclerosis (PP-MS) is correlated with global brain atrophy. Unfortunately, brain volume computation requires processing resources that are not widely available in clinical practice. Therefore, we decided to test the predictive role of retinal atrophy metrics on cognitive decline, applying them as a proxy of gray matter atrophy in PP-MS. METHODS: Twenty-five patients with PP-MS completed the Brief International Cognitive Assessment for Multiple Sclerosis and underwent spectral-domain optical coherence tomography (OCT) and 3.0-T magnetic resonance imaging. We tested, through a stepwise logistic regression, whether OCT metrics [retinal nerve fiber layer, ganglion cell + inner plexiform layer (GCIPL) and total macular volume] predicted cognitive impairment and explored the role of gray matter atrophy in mediating these correlations. RESULTS: Among OCT metrics, only GCIPL was associated with cognitive impairment (rp = 0.448, P = 0.036) and predictive of objective cognitive impairment (Wald [1] = 4.40, P = 0.036). Controlling for demographics, normalized brain volume and thalamic volume were correlated with GCIPL (rp = 0.427, P = 0.047 and rp = 0.674, P = 0.001, respectively) and cognitive scores (rp = 0.593, P = 0.004 and rp = 0.501, P = 0.017, respectively), with thalamic volume nearly mediating the association between GCIPL and cognition (Sobel z = 1.86, P = 0.063). CONCLUSIONS: The GCIPL thickness is a suitable measure of neurodegeneration. In comparison with brain atrophy, GCIPL offers higher histopathological specificity, being a pure correlate of neuronal loss, and may be a non-invasive, easy-to-perform way to quantitatively evaluate and monitor neuronal loss related to cognitive impairment in PP-MS.

Access, delivery and perceived efficacy of physiotherapy and use of complementary and alternative therapies by people with progressive multiple sclerosis in the United Kingdom: An online survey.

INTRODUCTION: All people with progressive MS in the United Kingdom should have access to physiotherapy through the National Health Service (NHS). However levels of access and delivery are unknown. Furthermore there is no research on perceived efficacy of physiotherapy or the use of complementary and alternative medicine in people with progressive MS in the United Kingdom. METHODS: An online survey was carried out via the UK MS Register. Inclusion criteria were diagnosis of progressive MS, a member of UK MS Register and 18 years or older. The survey asked participants regarding access and delivery of physiotherapy; perceived efficacy of physiotherapy and interventions received; barriers to accessing physiotherapy and use of complementary and alternative medicine. The following additional data were supplied from the UK MS Register: demographics, EQ5D, MSIS-29 physical and psychological sub-scales and geographical data. RESULTS: Total number of respondents was 1,298 from an identified 2,538 potential registrants: 87% could access physiotherapy services, 77% received physiotherapy from the NHS and 32% were currently receiving physiotherapy. The most common interventions received were home exercise programme (86%), exercises with a physiotherapist (74%) and advice/education (67%). 40% had recently used complementary and alternative medicine. Perceived efficacy of physiotherapy was high with 70% reporting it to be either 'beneficial' or 'very beneficial'. Main barriers to accessing physiotherapy were mobility, fatigue, continence, transport issues, requiring someone to go with them and pain. DISCUSSION: Access to physiotherapy was high with most people reporting it as beneficial. However 13% reported not having access indicating a gap in accessibility. Considering some of the barriers reported may allow physiotherapy services to address this gap in accessibility.

Hypothalamic damage in multiple sclerosis correlates with disease activity, disability, depression, and fatigue.

OBJECTIVES: Disturbances in the hypothalamo-pituitary axis are supposed to modulate activity of multiple sclerosis (MS). We hypothesised that the extent of HYP damage may determine severity of MS and may be associated with the disease evolution. We suggested fatigue and depression may depend on the degree of damage of the area. METHOD: 33 MS patients with relapsing-remitting and secondary progressive disease, and 24 age and sex-related healthy individuals (CON) underwent 1H-MR spectroscopy (1H-MRS) of the hypothalamus. Concentrations of glutamate + glutamin (Glx), cholin (Cho), myoinositol (mIns), N-acetyl aspartate (NAA) expressed as ratio with creatine (Cr) and NAA were correlated with markers of disease activity (RIO score), Multiple Sclerosis Severity Scale (MSSS), Depressive-Severity Status Scale and Simple Numerical Fatigue Scale. RESULTS: Cho/Cr and NAA/Cr ratios were decreased and Glx/NAA ratio increased in MS patients vs CON. Glx/NAA, Glx/Cr, and mIns/NAA were significantly higher in active (RIO 1-2) vs non-active MS patients (RIO 0). Glx/NAA and Glx/Cr correlated with MSSS and fatigue score, and Glx/Cr with depressive score of MS patients. In CON, relationships between Glx/Cr and age, and Glx/NAA and fatigue score were inverse. CONCLUSION: Our study provides the first evidence about significant hypothalamic alterations correlating with clinical outcomes of MS, using 1H-MRS. The combination of increased Glu or mIns with reduced NAA in HYP reflects whole-brain activity of MS. In addition, excess of Glu is linked to severe disease course, depressive mood and fatigue in MS patients, suggesting superiority of Glu over other metabolites in determining MS burden.

Cognitive impairment and magnetic resonance imaging correlates in primary progressive multiple sclerosis.

OBJECTIVES: To characterize cognitive impairment in primary progressive multiple sclerosis (PPMS) and to correlate the pattern of cognitive deficits with brain magnetic resonance imaging (MRI) volumetric data. MATERIALS AND METHODS: In a multicenter cross-sectional study, we recruited consecutive patients with PPMS as well as age, sex, and education level-matched healthy controls (HC). All participants underwent neuropsychological (NP) assessment, and brain MRI was performed in patients with PPMS for analysis of lesion load, subcortical GM volumes, and regional cortical volumes. RESULTS: We recruited 55 patients with PPMS and 36 HC. Thirty-six patients were included in the MRI analysis. Patients with PPMS performed significantly worse than HC in all NP tests. Subcortical GM volume was significantly correlated with all NP tests, except for Stroop Test, with the largest effect for the thalamus (r=-.516 [BVMT-R DR, P=.016 FDR-corrected] to r=.664 [SDMT, P<.001 FDR-corrected]). In the stepwise linear regression model, thalamic volume was the only predictor of performance in all NP tests. CONCLUSION: Cognitive impairment is common in PPMS and affects all evaluated cognitive domains. Subcortical GM volume, particularly of the thalamus, is a strong predictor of cognitive performance, suggesting it has a central role in the pathophysiology of PPMS-related cognitive dysfunction.

Potential treatment mechanisms in a mindfulness-based intervention for people with progressive multiple sclerosis.

OBJECTIVES: To explore putative mediators of a mindfulness-based intervention to decrease distress in people with multiple sclerosis (MS) and to explore the patients' perspectives on this intervention. DESIGN: We used an explanatory mixed methods design incorporating quantitative data from a pilot randomized control trial and a qualitative interview study with people who completed the mindfulness intervention. METHODS: People with MS (n = 40) completed standardized measures of distress (outcome), and acceptance, decentring, self-compassion, and self-efficacy (potential mediators). Semi-structured interviews (n = 15) of patients' experiences of the mindfulness intervention were analysed deductively and inductively. RESULTS: Decentring post-intervention explained 13% of the 3-month change in distress and between 27% and 31% of concurrent changes in distress. Acceptance changed only slightly, and as a result, the indirect effect accounts for only 2% of future distress and between 3% and 11% of concurrent distress. Qualitative data showed that acceptance and self-compassion needed more time to develop, whereas decentring could be implemented readily after being introduced in the sessions. Self-efficacy also had a large mediating effect. Participants in their interviews talked about group dynamics and prior expectations as essential elements that determine their engagement with the course and their level of satisfaction. CONCLUSIONS: Mindfulness interventions for people with a chronic progressive condition may benefit from focusing on helping them to accept daily challenges and teach them to recognize their thoughts and feelings, allowing time for acceptance and self-compassion to develop. Group dynamics also play a fundamental role in the success of the mindfulness interventions. Statement of Contribution What is already known on this subject? Mindfulness courses improve psychological well-being for people with chronic conditions. Mindfulness courses have been successful in improving psychological well-being and symptom management for people with multiple sclerosis but we do not know how these courses work. What does this study add? Decentering and self-efficacy appear to be key mechanisms leading to reduced distress. Acceptance and self-compassion may need more time and practice to develop. Group dynamics and expectations of the mindfulness courses were also important elements of mindfulness.

Localized atrophy of the thalamus and slowed cognitive processing speed in MS patients.

BACKGROUND: Deep gray matter (DGM) atrophy is common in multiple sclerosis (MS), but no studies have investigated surface-based structure changes over time with respect to healthy controls (HCs). Moreover, the relationship between cognition and the spatio-temporal evolution of DGM atrophy is poorly understood. OBJECTIVES: To explore DGM structural differences between MS and HCs over time in relation to neuropsychological (NP) outcomes. METHODS: The participants were 44 relapsing-remitting and 20 secondary progressive MS patients and 22 HCs. All were scanned using 3T magnetic resonance imaging (MRI) at baseline and 3-year follow-up. NP examination emphasized consensus standard tests of processing speed and memory. We performed both volumetric and shape analysis of DGM structures and assessed their relationships with cognition. RESULTS: Compared to HCs, MS patients presented with significantly smaller DGM volumes. For the thalamus and caudate, differences in shape were mostly localized along the lateral ventricles. NP outcomes were related to both volume and shape of the DGM structures. Over 3 years, decreased cognitive processing speed was related to localized atrophy on the anterior and superior surface of the left thalamus. CONCLUSIONS: These findings highlight the role of atrophy in the anterior nucleus of the thalamus and its relation to cognitive decline in MS.

Distress improves after mindfulness training for progressive MS: A pilot randomised trial.

BACKGROUND: Mindfulness-based interventions have been shown to effectively reduce anxiety, depression and pain in patients with chronic physical illnesses. OBJECTIVES: We assessed the potential effectiveness and cost-effectiveness of a specially adapted Skype distant-delivered mindfulness intervention, designed to reduce distress for people affected by primary and secondary progressive MS. METHODS: Forty participants were randomly assigned to the eight-week intervention (n = 19) or a waiting-list control group (n = 21). Participants completed standardised questionnaires to measure mood, impact of MS and symptom severity, quality of life and service costs at baseline, post-intervention and three-month follow-up. RESULTS: Distress scores were lower in the intervention group compared with the control group at post-intervention and follow-up (p < 0.05), effect size -0.67 post-intervention and -0.97 at follow-up. Mean scores for pain, fatigue, anxiety, depression and impact of MS were reduced for the mindfulness group compared with control group at post-therapy and follow-up; effect sizes ranged from -0.27 to -0.99 post-intervention and -0.29 to -1.12 at follow-up. There were no differences in quality-adjusted life years, but an 87.4% probability that the intervention saves on service costs and improves outcome. CONCLUSIONS: A mindfulness intervention delivered through Skype video conferences appears accessible, feasible and potentially effective and cost-effective for people with progressive MS.

A multimodal intervention for patients with secondary progressive multiple sclerosis: feasibility and effect on fatigue.

BACKGROUND: Multiple sclerosis is an autoimmune disease influenced by environmental factors. OBJECTIVES: The feasibility of a multimodal intervention and its effect on perceived fatigue in patients with secondary progressive multiple sclerosis were assessed. DESIGN/SETTING: This was a single-arm, open-label intervention study in an outpatient setting. INTERVENTIONS: A multimodal intervention including a modified paleolithic diet with supplements, stretching, strengthening exercises with electrical stimulation of trunk and lower limb muscles, meditation, and massage was used. OUTCOME MEASURES: Adherence to each component of the intervention was calculated using daily logs. Side-effects were assessed from a monthly questionnaire and blood analyses. Fatigue was assessed using the Fatigue Severity Scale (FSS). Data were collected at baseline and months 1, 2, 3, 6, 9, and 12. RESULTS: Ten (10) of 13 subjects who were enrolled in a 2-week run-in phase were eligible to continue in the 12-month main study. Of those 10 subjects, 8 completed the study and 6 subjects fully adhered to the study intervention for 12 months. Over a 12-month period, average adherence to diet exceeded 90% of days, and to exercise/muscle stimulation exceeded 75% of days. Nutritional supplements intake varied among and within subjects. Group daily average duration of meditation was 13.3 minutes and of massage was 7.2 minutes. No adverse side-effects were reported. Group average FSS scores decreased from 5.7 at baseline to 3.32 (p=0.0008) at 12 months. CONCLUSIONS: In this small, uncontrolled pilot study, there was a significant improvement in fatigue in those who completed the study. Given the small sample size and completer rate, further evaluation of this multimodal therapy is warranted.

Randomized controlled trial of a behavioral intervention targeting symptoms and physical activity in multiple sclerosis.

BACKGROUND: Exercise training is beneficial, but most persons with multiple sclerosis (MS) are sedentary and physically inactive. This has prompted a new focus on the promotion of lifestyle physical activity in MS. We previously designed, tested, and refined a behavioral intervention delivered through the Internet that successfully increased lifestyle physical activity in MS, but have not evaluated the effects on secondary symptomatic and health-related quality of life (HRQOL) outcomes. OBJECTIVE: We conducted a 6-month randomized controlled trial (RCT) that examined the efficacy of an Internet-delivered, behavioral intervention for improving outcomes of fatigue, depression, anxiety, pain, sleep quality, and HRQOL in 82 ambulatory persons with MS. The secondary aim was to replicate previous results regarding change in free-living physical activity. RESULTS: There was a significant and positive effect of the intervention on fatigue severity (p=.001, η ρ (2)=.15) and its physical impact (p=.008, η ρ (2)=.09), depression (p=.006, η ρ (2)=.10), and anxiety (p=.006, η ρ (2)=.10). There were non-significant improvements in pain (p=.08, η ρ (2)=.04), sleep quality (p=.06, η ρ (2)=.05), and physical HRQOL (p=.06, η ρ (2)=.05). We replicated our previous results by demonstrating an increase in self-reported physical activity (p=.001, η ρ (2)=.13). CONCLUSIONS: Our results support behavioral interventions targeting lifestyle physical activity as an alternative approach for managing symptoms in MS.

Diabetes insipidus as a rare cause of acute cognitive impairment in multiple sclerosis.

Multiple sclerosis (MS) is a complex neurodegenerative disease presenting with a diversity of clinical symptoms including palsy and cognitive impairment. We present a 59-year-old woman with a history of secondary progressive MS since 1987, who was referred to our department because of recent onset of confusion and polydipsia. Initial lab tests showed mildly elevated serum sodium levels and low urine osmolality. Under water deprivation, diuresis and low urine osmolality persisted and serum sodium levels rose above 150 mmol/l. Oral desmopressin resulted in normalisation of serum sodium as well as urine osmolarity, confirming a diagnosis of central diabetes insipidus. As drug-induced diabetes could be excluded, pituitary magnetic resonance imaging (MRI) was performed. A demyelinating lesion was detected in the hypothalamus. The patient was started on oral desmopressin treatment (0.2 mg/day). Fluid intake and serum sodium levels have since remained normal. In summary, we report the rare case of a patient presenting with diabetes insipidus due to progressive MS. Diabetes insipidus should be considered in MS patients who develop new onset of polydipsia.

Comparison of the effect of two types of acupuncture on quality of life in secondary progressive multiple sclerosis: a preliminary single-blind randomized controlled trial.

OBJECTIVE: To compare the effect of two types of acupuncture on the quality of life of individuals with secondary progressive multiple sclerosis and provide preliminary evidence regarding the safety of this intervention for this population. DESIGN: Preliminary single-blind randomized controlled trial. SETTING: Outpatient attendance at rehabilitation unit. PARTICIPANTS: Fourteen participants with secondary progressive multiple sclerosis. INTERVENTIONS: Chinese medical acupuncture or minimal acupuncture. Participants received 10 treatments over five weeks. MEASURES: Multiple Sclerosis Impact Scale 29, Fatigue Severity Scale and General Health Questionnaire 12 were measured pre and post intervention. Adverse events and other responses during treatment were recorded prospectively. RESULTS: Participants receiving minimal acupuncture demonstrated statistically significant greater improvement in the Multiple Sclerosis Impact Scale 29 psychological subscale compared with those receiving Chinese medical acupuncture in an intention-to-treat analysis (P=0.04), with mean change in Chinese acupuncture group of 6.0 (SD 13.9) and in minimal acupuncture group of 23.0 (SD 21.0). No other statistically significant difference between the groups was found. No major adverse events were noted. Minor adverse events such as lower limb muscle spasms or pain were noted in some participants in both intervention groups. CONCLUSION: Minimal acupuncture resulted in greater improvement of Multiple Sclerosis Impact Scale 29 psychological subscale compared with Chinese medical acupuncture. No other differences between the groups were found. In view of the small sample these results are not conclusive. This study provides preliminary evidence to suggest that acupuncture is safe for people with secondary progressive multiple sclerosis. A large-scale trial is required to provide more definitive evidence.

A systematic approach to analyse health-related quality of life in multiple sclerosis: the GEDMA study.

OBJECTIVE: To describe a holistic and comprehensive approach to the assessment of sufferer's perceptions of health-related quality of life (HRQoL) in a cohort of multiple sclerosis (MS) patients. METHODS: The GEDMA (Grupo de Enfermedades Desmielinizantes de Madrid, in Spanish) study is an ongoing longitudinal survey using quantitative and qualitative methodologies. The baseline cohort consisted of a large sample of MS patients recruited from 13 hospitals in Madrid, Spain. Using a standardized protocol we collected data concerning the sociodemographic and health status characteristics of patients, as well as implementing a modified Spanish version of the Functional Assessment of Multiple Sclerosis quality of life instrument Primary caregivers were interviewed using a specific protocol combined with the Zarit Burden Interview. RESULTS: The index cohort comprised 371 MS patients (68.7% female) of mean age 38.9+/-0.9 years. Age, sex and clinical form distribution were similar to other MS population-based surveys. There were 258 (69.5%) relapsing-remitting (RR) MS patients and 113 (30.5%) progressive MS patients. More than one-third of the married patients with progressive MS and almost a quarter of the RRMS patients separated or divorced following a diagnosis of MS; 71.3% of the progressive MS patients as well as 65.8% of the RRMS patients were unemployed as a consequence of the disease. Qualitative analysis showed that friendship and family relationships and occupational status were the most significant dimensions influenced by MS. On the other hand, the speech analysis of primary caregivers showed that emotional burden was related to patients' physical disability. Furthermore, primary caregivers described the influence of MS on their own occupational status, their nonacceptance of the disease, a perception of a lack of support by other members of the family as well as a 'selfish and intransigent' attitude of the patients themselves. CONCLUSIONS: The analysis of the GEDMA cohort provides valuable information that helps clarify the impact of MS on patients' HRQoL.

Mindfulness of movement as a coping strategy in multiple sclerosis. A pilot study.

This study investigated the effectiveness of a short course of mindfulness of movement to help with symptom management in eight people with multiple sclerosis. Progress was compared to a control group who were asked to continue with their current care. Each participant received six individual one-to-one sessions of instruction. They were also provided with audio and videotape aides. Each participant was assessed on a test of balance, pre- and post-intervention, and at 3-month follow-up. All participants completed a rating of change of 22 symptoms relevant to multiple sclerosis. A close relative or friend was also asked to assess independently the degree of change. The mindfulness group reported improvement over a broad range of symptoms. This was verified by the relatives' independent rating and maintained at 3 month follow-up. The control group showed no improvement but instead tended towards a deterioration on many of the items. The physical assessment of balance also showed a significant improvement for the mindfulness group. This improvement was maintained at 3 month follow-up. In conclusion, training in mindfulness of movement appeared to result in improved symptom management for this group of people with multiple sclerosis. This was a pilot study, using small numbers, so the results need to be treated with caution. Several improvements to the experimental design are suggested. The role of individual therapeutic ingredients is discussed.
