Multiple sclerosis: Neurofilament light chain antibodies are correlated to cerebral atrophy.

Objective: To evaluate markers of axonal damage in CSF and serum of patients with different subtypes of MS in relation to measures of disease progression on MRI. Methods: In 51 patients with MS (21 relapsing-remitting, 20 secondary progressive, 10 primary progressive), levels of heavy and light neurofilaments (NfH and NfL) and antibodies to neurofilaments (anti-NfL and -NfH) as well as the total immunoglobulin G (IgG) were analyzed. MRI analysis included T2 hyperintense, T1 hypointense, and gadolinium enhancing lesions and markers of cerebral atrophy (ventricular and parenchymal fractions). Results: For the total group, correlations were found between the anti-NfL index and the parenchymal fraction (PF) (r = −0.51, p < 0.001), T2 lesion load (r = 0.41, p < 0.05), ventricular fraction (r = 0.37, p < 0.05), and T1 lesion load (r = 0.37, p < 0.05). For the anti-NfH index, a correlation was found with the PF (r = −0.39, p < 0.05). No correlations were found between the IgG index and MRI measures. Conclusions: Intrathecal production of anti-NfL antibodies may serve as a marker of tissue damage, particularly axonal loss, in MS.

Is Short-Term Palliative Care Cost-Effective in Multiple Sclerosis? A Randomized Phase II Trial

CONTEXT Palliative care is being advocated for noncancer patients but needs evidence of effectiveness and cost-effectiveness. OBJECTIVE We evaluated the cost-effectiveness of a new palliative care service for people with multiple sclerosis (MS). METHODS We used a randomized fast-track Phase II controlled trial. Patients in South East London who were severely affected by MS were referred by clinicians to the trial. After baseline interview, patients were randomly allocated to either a multiprofessional palliative care team (PCT) immediately (fast track) or the control care group who continued best usual care for three months and then were offered the PCT. Data were collected at baseline, 6, 12, 18, and 26 weeks on use of services, patient symptoms, other outcomes, and caregiver burden. RESULTS Fifty-two patients were randomized: 25 fast track and 21 control patients completed the trial. There was a high level of disability, and mean Expanded Disability Status Scale score was 7.7 (median 8, standard deviation 1.0). At 12 weeks, caregiver burden was 4.47 points lower (95% confidence interval [CI]: 1.05-7.89) in the fast track compared to the control group. Mean service costs, including inpatient care and informal care, over the 0-12-week follow-up were pound1,789 lower for the fast-track group (bootstrapped 95% CI: - pound5,224 to pound1,902). There was a trend toward lower community costs in the fast-track group and no differences in costs to informal caregivers. CONCLUSIONS The trial suggests that short-term palliative care for people severely affected by MS and their caregivers will be cost-effective and warrants further study. The fast-track trial design could be used to assess this.

Axonal degeneration in the pathogenesis of multiple sclerosis.

Axonal degeneration plays an important role in the accumulation of disability in patients with multiple sclerosis (MS). Pathological studies have demonstrated axonal damage, particularly in areas of acute inflammation and demyelination, and in chronic lesions. Axonal loss and its progression, which is associated with neurological disability, has also been demonstrated by magnetic resonance imaging (MRI) studies. The mechanisms of axonal loss are uncertain, but may involve axonal degeneration secondary to demyelination, or damage to the axonal cytoskeleton. Inflammatory mediators, including cytokines and proteolytic enzymes may contribute to axonal damage, as may nitric oxide. Axonal destruction may also be due to immune attack directed at axonal components. The realisation that axonal degeneration is a fundamental component of MS that may occur early in the disease course should alter the approach to management and open avenues to a more targeted immunotherapy aimed at reducing the progression of disability.

Palliative care for people severely affected by multiple sclerosis: evaluation of a novel palliative care service

Multiple sclerosis results in both physical and psychological disability but some patients have needs that are not adequately met by existing services. Our objective was to explore whether a new palliative care service improved outcomes for people severely affected by multiple sclerosis. A delayed intervention randomized controlled trial was undertaken with multiple sclerosis patients deemed by staff to have palliative care needs. The intervention was a multiprofessional palliative care team assessment and follow-up. The intervention group was offered the team immediately (fast track, FI); the control group continued best standard care and then offered the team after 3 months (standard intervention, SI). The main outcome measures were: patient reported issues using the Palliative Care Outcome Scale and Multiple Sclerosis Impact Scale at 12 weeks and caregiver burden using the Zarit Burden Inventory. Sixty-nine people were referred to the service; 52 consented or were eligible to be randomized (26 to the FI and 26 to the SI groups). At 12 weeks people in the FI group had an improvement (mean change —1.0) in the total score of 5 key symptoms whereas there was deterioration in the SI group (mean change 1.1, F = 4.75, p = 0.035). There was no difference in the change in general Palliative Care Outcome Scale or Multiple Sclerosis Impact Scale scores. There was an improvement in caregiver burden in the FI group and a deterioration in the SI group (F = 7.60, p = 0.013). Involvement with the palliative care service appeared to positively affect some key symptoms and reduced informal caregiver burden.

Association of British Neurologists: revised (2015) guidelines for prescribing disease-modifying treatments in multiple sclerosis

In June 1999, the Association of British Neurologists (ABN) first published guidelines for the use of the licensed multiple sclerosis (MS) disease-modifying treatments (at that time β-interferon and glatiramer acetate). The guidelines were revised in 2001 and have been periodically updated since then. In 2002, following the negative assessment of these treatments by the National Institute for Health and Care Excellence (NICE), the MS risk-sharing scheme started, in which patients eligible according to the 2001 ABN guidelines were provided with treatment funded through the UK National Health Service (NHS), and monitored annually for up to 10 years.1 Recruitment to the risk-sharing scheme cohort is complete. Pending a future final evaluation, the UK Department of Healths instruction to NHS funders remains in place: that patients who fulfil the ABN criteria should continue to receive treatment funded through the NHS. The British neurological community has fully accepted the risk-sharing scheme for prescribing β-interferon and glatiramer acetate. Approximately 70 ‘treating centres’ have recruited >5000 patients between 2002 and 2005, and these have been monitored annually for 10 years; many more patients have received these treatments since 2005. The ABN published revised guidelines in 2007, and then again in 2009, following the licensing of natalizumab and mitoxantrone. This 2015 revised guideline replaces former versions. It includes all newly approved or licensed treatments for MS and represents a consensus concerning their use. These guidelines will require future revision as other treatments receive approval (eg, daclizumab and ocrelizumab): we suggest they are reviewed after an interval of no longer than 12 months. The guideline is not intended to provide a complete description of the possible complications and monitoring of disease-modifying treatments in MS; we refer prescribing neurologists to the relevant summaries of product characteristics. MS is a complex disease. Perhaps uniquely in neurology its clinical course is characterised …

Osteoporosis in multiple sclerosis

Fractures resulting from osteoporosis are a major cause of morbidity and mortality in the developed world. People with multiple sclerosis experience reduced mobility and are susceptible to falls. Glucocorticoid use and reduced mobility are known risk factors for osteoporosis. This paper is a review of osteoporosis in people with multiple sclerosis, looking at its prevalence, risk factors and possible mechanisms. We also review management guidelines for osteoporosis in the general population and use these to propose guidelines for osteoporosis management amongst multiple sclerosis patients. A number of studies have examined the incidence of reduced bone mineral density amongst people with multiple sclerosis; the majority provide convincing evidence that bone mineral density is significantly reduced in multiple sclerosis patients. The most significant risk factors appear to arise from the chronic disease process of multiple sclerosis and not from glucocorticoid use. There are currently no guidelines or consensus as how best to treat osteoporosis amongst multiple sclerosis patients despite their being at an increased risk. We propose an algorithm for the screening and treatment of osteoporosis in people with multiple sclerosis.

Loss and change: experiences of people severely affected by multiple sclerosis

This study aimed to explore important issues for people severely affected by multiple sclerosis (MS). Individual interviews were conducted with 23 people with MS (PwMS) and 17 informal carers, the data relating to 32 PwMS. Information was obtained about 19 females and 13 males, with a mean age of 55, median time from diagnosis was 14.5 years, and physical disabilities ranged from mild to severe, although fifteen patients had severe disabilities. Twenty-six of the 32 individuals were unable to walk, 24 were catheterised, and 18 had considerably impaired or no upper limb function. Personal issues in relation to loss and change, particularly in terms of losses of or changes in physical abilities, including maintaining mobility, independence, relationships and social role were raised commonly in response to an open-ended question about what issues were important in living with MS. Coping with MS requires individuals to deal with the losses and changes brought about by their illness. Our study suggests that even patients who have had MS for many years and are now severely affected continue to experience loss and change. We recommend that attention be given to emotional support which specifically addresses three main areas of dealing with loss and change for people that are severely affected - physical issues, independence and relationships. Palliative care providers may have expertise in managing loss that could be useful for these patients in partnership with neurological services.

Study protocol: delayed intervention randomised controlled trial within the Medical Research Council (MRC) Framework to assess the effectiveness of a new palliative care service

BackgroundPalliative care has been proposed to help meet the needs of patients who suffer progressive non-cancer conditions but there have been few evaluations of service development initiatives. We report here a novel protocol for the evaluation of a new palliative care service in this context.Methods/DesignUsing the MRC Framework for the Evaluation of Complex Interventions we modelled a new palliative care and neurology service for patients severely affected by Multiple Sclerosis (MS). We conducted qualitative interviews with patients, families and staff, plus a literature review to model and pilot the service. Then we designed a delayed intervention randomised controlled trial to test its effectiveness as part of phase II of the MRC framework. Inclusion criteria for the trial were patients identified by referring clinicians as having unresolved symptoms or psychological concerns. Referrers were advised to use a score of greater than 8 on the Expanded Disability Scale was a benchmark. Consenting patients newly referred to the new service were randomised to either receive the palliative care service immediately (fast-track) or after a 12-week wait (standard best practice). Face to face interviews were conducted at baseline (before intervention), and at 4–6, 10–12 (before intervention for the standard-practice group), 16–18 and 22–24 weeks with patients and their carers using standard questionnaires to assess symptoms, palliative care outcomes, function, service use and open comments. Ethics committee approval was granted separately for the qualitative phase and then for the trial.DiscussionWe publish the protocol trial here, to allow methods to be reviewed in advance of publication of the results. The MRC Framework for the Evaluation of Complex Interventions was helpful in both the design of the service, methods for evaluation in convincing staff and the ethics committee to accept the trial. The research will provide valuable information on the effects of palliative care among non-cancer patients and a method to evaluate palliative care in this context.

Randomised controlled trial of a new palliative care service: Compliance, recruitment and completeness of follow-up

BackgroundPalliative care has been proposed for progressive non-cancer conditions but there have been few evaluations of service developments. We analysed recruitment, compliance and follow-up data of a fast track (or wait list control) randomised controlled trial of a new palliative care service – a design not previously used to assess palliative care.Methods/DesignAn innovative palliative care service (comprising a consultant in palliative medicine, a clinical nurse specialist, an administrator and a psychosocial worker) was delivered to people severely affected by multiple sclerosis (MS), and their carers, in southeast London. Our design followed the MRC Framework for the Evaluation of Complex Interventions. In phase II we conducted randomised controlled trial, of immediate referral to the service (fast-track) versus a 12-week wait (standard best practice). Main outcome measures were: compliance (the extent the trial protocol was adhered to), recruitment (target 50 patients), attrition and missing data rates; trial outcomes were Palliative Care Outcome Scale and MS Impact Scale.Results69 patients were referred, 52 entered the trial (26 randomised to each arm), 5 refused consent and 12 were excluded from the trial for other reasons, usually illness or urgent needs, achieving our target numbers. 25/26 fast track and 21/26 standard best practice patients completed the trial, resulting in 217/225 (96%) of possible interviews completed, 87% of which took place in the patients home. Main reasons for failure to interview and/or attrition were death or illness. There were three deaths in the standard best practice group and one in the fast-track group during the trial. At baseline there were no differences between groups. Missing data for individual questionnaire items were small (median 0, mean 1–5 items out of 56+ items per interview), not associated with any patient or carer characteristics or with individual questionnaires, but were associated with interviewer.ConclusionThis is the first time a fast track (or wait list) randomised trial has been reported in palliative care. We found it achieved good recruitment and is a feasible method to evaluate palliative care services when patients are expected to live longer than 3–6 months. Home interviews are needed for a trial of this kind; interviewers need careful recruitment, training and supervision; and there should be careful separation from the clinical service of the control patients to prevent accidental contamination.Trial RegistrationClinical Trials.Gov NCT00364963

Evaluation of a new model of short-term palliative care for people severely affected with multiple sclerosis: a randomised fast-track trial to test timing of referral and how long the effect is maintained

Aims In this randomised fast-track phase II trial, the authors examined (1) whether the timing of referral to short-term palliative care (PC) affected selected outcomes, and (2) the potential staff-modifying effect of the short-term PC intervention (whether the effects were sustained over time after PC was withdrawn). Methods PC comprised a multiprofessional PC team that provided, on average, three visits, with all care completed by 6 weeks. Recruitment commenced in August 2004 and continued for 1 year. Follow-up was performed for 6 months in both groups. Outcomes were a composite measure of five key symptoms (pain, nausea, vomiting, mouth problems and sleeping difficulty) using the Palliative care Outcome Scale–MS Symptom Scale, and care giver burden was measured using the Zarit (Care Giver) Burden Interview (ZBI). Results 52 patients severely affected by multiple sclerosis were randomised to receive PC either immediately (fast-track group) or after 12 weeks (control group). Patients had a high level of disability (mean Expanded Disability Status Scale: 7.7; median: 8; SD: 1). Following PC, there was an improvement in Palliative care Outcome Scale–MS Symptom Scale score and ZBI score. A higher rate of improvement in ZBI score was seen in the fast-track group. After withdrawal of PC, effects were maintained at 12 weeks, but not at 24 weeks. Conclusions Receiving PC earlier has a similar effect on reducing symptoms but greater effects on reducing care giver burden, compared to later referral. In this phase II trial, the authors lacked the power to detect small differences. The effect of PC is maintained for 6 weeks after withdrawal but then appears to wane.
