The next generation
Training the next generation of MSologists is one of my priorities.
I helped arrange and teach on the Pan-London Calman Specialist Registrar (SpR) teaching day yesterday. It was great to see so many young trainee neurologists attending; thank you. And to the speakers for giving up their time to teach and inspire the next generation of neurologists to become MSologists; thank you.
I hope you all enjoyed the day the following is the programme.
I was impressed by the level of engagement of the audience. I was particularly happy with an insight from one of the trainees who suggested we should be managing MS they way rheumatologists manage RA; i.e. early and aggressively. This was music to my ears. I have been pushing the treat-2-target RA paradigm for MS for several years now. The only difference is that our treatment targets have gradually become more ambitious as we have moved from NEDA-1 (relapses) to NEDA-3 (MRI activity) to preventing end-organ damage as measured with MRI (normalising the rate of brain volume loss or NEDA-4) and normalising CSF and blood neurofilament levels (NEDA-5) and beyond. What I mean by beyond is that our ultimate aim is to cure people of having MS and to allow them to get to old age with as much brain as possible. Is this too ambitious?
The following is my presentation from yesterday that can be downloaded from my slideshare site.
At the end of my session, we got into a lively debate about whether or not everyone with MS needs to be treated. Obviously not, based on my presentation only people with active MS are eligible for treatment. Those who have inactive MS cannot be treated under current NHS England guidelines and if they remain inactive they will hopefully end-up having benign MS. Surely the aim of our treatments is to convert everyone with MS into having inactive MS that will hopefully turn out to be benign MS after 25-30 years of follow-up. What we did not cover in this mini-debate is what is active MS? Should it include smouldering MS?
If any of the trainees are reading this post can I please recommend that you read the following posts I have recently done and to bookmark my MS-Selfie site that is still under development.

What the eye doesn’t see?
The problem: ‘MS has become an MRIscopic disease’.
The diagnosis of MS remains clinical and is underpinned by the need to show (1) dissemination in time (typically new activity 4 weeks apart or the presence of locally produced oligoclonal IgG bands in the spinal fluid) and (2) dissemination is space (symptoms and/or signs affecting two different pathways in the CNS) and (3) the exclusion of other possible diagnoses. It is clear that based on these criteria you don’t necessarily need to have visible, or specific, MRI lesions to make a diagnosis of MS. However, neurologists feel uncomfortable making a diagnosis of MS or CIS if there are no visible lesions on MRI. In other words from a practical and clinical perspective, MS has become a macroscopic or MRIscopic disease. Therein lies the rub.
MS is a biological disease that is characterised pathologically by multifocal inflammatory lesions that cause demyelination and variable degrees of axonal loss. Please note I have dropped using the term white matter. MS is clearly both a white and grey matter disease with more than half the lesion burden in the largely MRI-lesion-invisible grey matter component (see study below). Even in the white matter where it is easier to see lesions the resolution of an MRI scan is down to about 3-4 mm. Many more lesions are found pathologically than what is seen on MRI or the naked eye. Therefore, particularly early on in the course of the disease, there will be a small number of people with MS with one or no lesions who have MS.
A very small lesion in a strategic pathway can cause typical symptoms and signs, but when you investigate many of these patients with an MRI scan you see no obvious lesion in the expected area. This happens more often than not with a so-called internuclear ophthalmoplegia (INO); a very specific eye movement problem that presents with double-vision on looking to the left or right. This is an example of a microscopic lesion causing an MS attack. This is why we shouldn’t be using MRI to confirm, or make, a diagnosis of relapse in pwMS.
Kutzelnigg et al. Cortical demyelination and diffuse white matter injury in multiple sclerosis. Brain. 2005 Nov;128(Pt 11):2705-12.
Focal demyelinated plaques in white matter, which are the hallmark of multiple sclerosis pathology, only partially explain the patient’s clinical deficits. We thus analysed global brain pathology in multiple sclerosis, focusing on the normal-appearing white matter (NAWM) and the cortex. Autopsy tissue from 52 multiple sclerosis patients (acute, relapsing-remitting, primary and secondary progressive multiple sclerosis) and from 30 controls was analysed using quantitative morphological techniques. New and active focal inflammatory demyelinating lesions in the white matter were mainly present in patients with acute and relapsing multiple sclerosis, while diffuse injury of the NAWM and cortical demyelination were characteristic hallmarks of primary and secondary progressive multiple sclerosis. Cortical demyelination and injury of the NAWM, reflected by diffuse axonal injury with profound microglia activation, occurred on the background of a global inflammatory response in the whole brain and meninges. There was only a marginal correlation between focal lesion load in the white matter and diffuse white matter injury, or cortical pathology, respectively. Our data suggest that multiple sclerosis starts as a focal inflammatory disease of the CNS, which gives rise to circumscribed demyelinated plaques in the white matter. With chronicity, diffuse inflammation accumulates throughout the whole brain, and is associated with slowly progressive axonal injury in the NAWM and cortical demyelination.
MMR to test or not to test?
Despite Wakefield being discredited and struck off the medical register in the UK he, and the ‘Anti-Vax’ brigade, is still having a profound impact on society, which is gradually beginning to filter down to how we manage MS. Why?
The number of children receiving the MMR vaccine in England is falling. A report from NHS Digital shows that coverage of the MMR vaccine for children reaching their 2nd birthday has fallen the fourth successive year. Uptake was 91.2% in England in 2017-18, down from 91.6% in 2016-17 and the lowest level since 2011-12 (BMJ). The downside of this is that we have seen an epidemic of measles, yes measles, in the UK. Between 1 January 2018 and 31 October 2018, there have been 913 laboratory-confirmed measles cases in England (Public Health England).
So what has this got to do with MS? Well, unvaccinated people also get MS. If you are unvaccinated and have not been exposed to the wild virus you are at risk of acquiring these infections as an adult. If you then decide to go onto longterm immunosuppression to treat your MS you are putting yourself at risk of serious complications from these infections. In addition, once you are on a longterm immunosuppressive therapy you can’t be vaccinated with the MMR vaccine as it is a live attenuated vaccine.
Sophie Arie: Speaking up for vaccination: five minutes with…Peter Hotez. BMJ 2018.
The professor and dean of the National School of Tropical Medicine at Baylor College of Medicine, in Texas, explains to Sophie Arie why he’s written a book about his daughter
“I became alarmed at the sharp drops in vaccine coverage. Children are now dying because of the “anti-vax” movement. Most of the children who died in the latest influenza epidemic in the US weren’t vaccinated.
“The anti-vax movement is extremely well organised, with huge funding and bandwidth. There are 480 anti-vaccine websites. Of course, people are challenging their paediatricians because of what they’ve read.
“But there is general silence on the pro-vaccine side. The US government has been conspicuously silent. Unicef and the World Health Organization are not recognising the threat this poses to low and middle-income countries.
“We have enabled this by refusing to recognise that public engagement is important for scientists. When I was doing my training the message was ‘you’re not supposed to engage the public.’ It was seen as self-promotion. It may be that it’s just not in the DNA of our profession. But if you are silent you won’t achieve your goals. We have to speak up.
“I’ve written my book, Vaccines Did Not Cause Rachel’s Autism, as a vaccine scientist, a paediatrician, and an autism dad. I’ve just spoken in simple, declarative language which is not what we scientists are taught to do. I’ve written about my personal experience and I’ve just said, ‘vaccines don’t cause autism’ and here’s why. The Institute of Medicine would say something like ‘the preponderance of evidence today cannot show any clear link between vaccines and autism.’ That sounds to a layperson like hedging.
“I’m hoping it can make as much difference as a book can make for parents who are sitting on the fence, for paediatricians who are feeling under siege, and journalists who still frame this as a ‘debate’ when there is no debate.
“Colleagues are supporting me privately but not speaking out themselves. The anti-vax movement is very aggressive. Who wants to receive an email while standing in line for their morning bagel to find themselves being compared to Hitler? It’s not very nice.
“We need to give physicians and scientists the tools and training to communicate. It’s good that some grants for funding now demand that you provide an advocacy plan for your science. This needs to become part of the way we think.”

Should we deny non-whites access to DMTs?
Lack of evidence does not mean lack of efficacy.
If you are a non-Caucasian pwMS you will become disabled quicker than your Caucasian counterparts. The evidence that so-called ‘non-whites’, which includes African-Americans, Africans and Asian do worse than ‘whites’ is pretty well accepted. However, most of this data was derived from the pre-DMT and 1st-generation, or injectable (IFNbeta and GA), DMT eras. The question of whether or not the same now holds true in the post-Natalizumab era is unclear.
Pharmacotherapy of multiple sclerosis (MS) is evolving rapidly. Despite impressive gains over the past 2 decades in the approval of multiple drugs for MS, lack of recruitment of minorities with MS in phase 3 clinical studies is a persistent concern and skews efficacy and disability data.
I am alone and feeling vulnerable
The following study explores the possible causes of loneliness.
What we now need to do is learn from this and do something about it. That is why we are trying to set-up a programme of local MS wellness champions to try and tackle this problem. In fact, I am meeting with Alyson McGregor, the National Director of ‘Altogether Better‘, this afternoon to ask her to help us with our social capital project. I am sure we can model our #PatientActivation programme on their ‘Altogether Better Health Champions‘ model and achieve similar outcomes.
Balto et al. Loneliness in Multiple Sclerosis: Possible Antecedents and Correlates. Rehabil Nurs. 2019 Jan/Feb;44(1):52-59.
DESIGN: Cross-sectional, comparative study of MS (n = 63) and healthy adults (n = 21).
METHODS: Data were collected using self-reports of loneliness and antecedents and correlates and analyzed using inferential statistics.
FINDINGS: Those with MS had significantly higher loneliness scores than healthy adults (p < .05), and this was explained by employment status. Possible antecedents included marital status (p < .05), upper extremity function (r= -.28, p < .03), social disability frequency (r= -.49, p < .00), social disability limitations (r= -.38, p < .00), and personal disability limitations (r= -.29, p < .03). Social disability frequency (beta = -.41, p < .001) and marital status (beta = -.23, p < .046) accounted for 25% of the variance in loneliness scores. Possible correlates included depression (r= .49, p < .00), cognitive fatigue (r= .34, p < .01), psychosocial fatigue (r= .30, p < .02), and psychological quality of life (r= .44, p < .00).
CONCLUSIONS: We provide evidence of loneliness in persons with MS, and this is associated with possible antecedents (e.g., marital status and disability limitations) and correlates (e.g., depression and fatigue).
CLINICAL RELEVANCE: Loneliness should be recognized clinically as an important concomitant of MS.

#ThinkHand – taking telerehabilitation one step further
We are continuing to make the case for our #ThinkHand campaign with several outputs in 2018, which are being used to support our work in this area. I am very proud that ORATORIO-HAND, a phase-3b study of ocrelizumab in PPMS, which will include patients with an EDSS of up to 8.0 and will start recruiting in the first quarter of 2019. The primary outcome in ORATORIO-HAND is the 9-HPT; this in itself is a first and a major milestone for the field of MS.
These two studies are remarkable for several reasons. Firstly, these trials are challenging the dogma that MS is not modifiable beyond EDSS 7.0, secondly, it is shifting the focus away from the lower limbs and EDSS to a new primary outcome the 9-HPT and, finally, it is giving people with advanced MS hope in valuing their hand function and independence.
As part of our #ThinkHand campaign Alison Thomson, our research designer, in collaboration with the Agency of Design, helped design an upper limb rehabilitation tool called under&over, which we launched at ECTRIMS-2018 in Berlin. We have now been successful in obtaining a grant to test whether or not under&over will work as a rehab tool and are planning a remote web-based study to test it. Again our primary outcome will be stabilisation, or improvement, in the performance of the 9HPT only this time we will be using our cardboard 9HPT.
Would you be interested in helping us design the study and/or participating?
A prospective, randomized, three-arm, evaluator blinded study to demonstrate the feasibility of a telerehabilitation (TR) program in individuals with ambulatory deficits secondary to Multiple Sclerosis (MS) and evaluate its efficacy when compared to conventional on-site physical therapy (PT) was completed. Thirty participants were evaluated at baseline and randomized to one of three groups with intervention lasting 8 weeks: Group 1 (control)- customized unsupervised home-based exercise program (HEP) 5 days a week; Group 2 (TR)- remote PT supervised via audio/visual real-time telecommunication twice weekly; Group 3 (PT)- in-person PT at the medical facility twice weekly. Outcomes included patient reported outcomes (PROs) obtained through questionnaires, and measurements of gait and balance performed with bedside tests and a computerized system. Functional gait assessment improved from baseline in all three groups. There were no significant differences between the TR and the conventional PT groups for a variety of outcome measures. TR is a feasible method to perform PT in persons with MS and has comparable efficacy to conventional in-person PT as measured by patient reported outcomes and objective outcomes of gait and balance.
CoI: The design, development and manufacture of the under&over rehab tool and the follow-on web-based rehab study has been kindly funded by unrestricted grants from F. Hoffmann-La Roche AG.
