Pre-natalizumab vs. after-natalizumab

I view MS as having two eras, the pre-natalizumab era and after-natalizumab era. Natalizumab has been a transformational therapy for so many reasons and this study provides a little more evidence to support this position.

Guest Post: teenage girls and smoking

Barts-MS often takes in school students for work experience. We ask some of the students to take on small projects and to write reports. One of our research programmes is to prevent MS. Smoking is an important risk factor for developing MS; smokers have an approximately 50% higher risk of developing MS.


A large and increasing problem in the UK is teenage smoking, particularly amongst teenage girls. We, therefore, asked Amy Sankey, one of our work experience students, to explore this issue amongst her peers at her school. 

The following is Amy's survey and report back. We were very impressed with Amy's commitment and attitude and sincerely hope she achieves her aim of getting into her University of choice to study chemistry.

Newsflash Medical Cannabis to be Legalised in the UK. The value of People power

Today the UK have announced that they plan to legalise cannabis for medical use and so join the Republic of Ireland, Germany, The Netherlands and Israel.

Therefore, a new treatment option for symptom control and probably progressive MS (yes a neuroprotective) may be coming your way.

Stornoway research day series: Holistic care of MS patients

MS specialist nurse Mhairi Coutts discusses the definition of holistic care. She outlines how to use the concept as part of caring for people with MS. She argues that a holistic, multi-disciplinary approach is essential to meeting the needs of patients and caring for them effectively.

Switching from Natalizumab to Fingolimod

People taking natalizumab often have to stop and switch to something else, such as if you are JC virus positive and have been on previous immunosuppression.

You don't want to immunosuppress in case the person has sub clinical PML. 
You don't want to wait too long because disease will reactivate.

What happens if the time interval is only a month between stopping and starting?

NHS constitution. The DrK Update

This post is for anyone who lives (with MS) in or works (neuros & nurses) in England. This relates t a recent post on the NHS constitution

Update: This is a Comment Made by DrK. As many of you don't read comments I thought I would post this.

"Much of what the barrister said should worry neurologists who feel they can stick to the old days, being highly selective in what they tell pwMS, or simply wait and see".

Firstly, in civil cases, it does not have to be demonstrated that *not* prescribing DMT *has led* (without doubt) to deterioration in the individual (the smoking gun concept). What needs to be shown is that - on the balance of probabilities - waiting and seeing has materially contributed *to the risk of deterioration*.

Secondly, this is very much about the duty of care and offering choice that *provided a pwMS fulfils the criteria* for DMT, options *have* to be discussed. Many colleagues may not be aware of the crystal clear implication of this paragraph in the NHS constitution.


Remember. Ignorance of the Rules means you loose.

Diagnosis: bigger is not always better

When you have a first demyelinating event, you get a scan to see if there are lesions in time (lesions of different age) and space (lesions in different places). 

Does it matter how big the scanner is?

How can we create a prevention study in MS? We need your help!

Many of you will have seen the previous post on Preventive Neurology and the new initiative we are setting up to work towards preventing MS. As many of the comments have identified, this is a difficult area to study. We have to find a way to start monitoring people before they develop the earliest signs of MS.

How do CD20-depleting antibodies work..To T or Not to T that is the Question.

As soon as rituximab and then ocrelizumab, which are both CD20 depleting antibodies, were shown to influence relapsing MS, implicating B cells as a target for MS.

We had a flow of papers indicating that T cells express weak amounts of CD20. This view is trotted out time and time again, if you mention B cells as an issue.

These T cells are depleted by rituximab and so the T cell biologists have clung to the idea that rituximab works by depleting T cells.

Palanichamy A, Jahn S, Nickles D, Derstine M, Abounasr A, Hauser SL, Baranzini SE, Leppert D, von Büdingen HC. Rituximab efficiently depletes increased CD20-expressing T cells in multiple sclerosis patients. J Immunol. 2014;193:580-586.

Is this a desperate view to cling to? 

I think so

(A) The Tcellers are happy to accept that depleting 5% of T cells (i.e. the CD20+ T cell subsets) inhibits MS, whilst dismissing the fact that 70% depletion of (CD4) has minimal effect. This makes minimal sense to me

(B) However, it is not only CD20 that implicates activity on B cells. 

Do T cells express Bruton Tyrosine Kinase and CD19, because these B cell depleting agents also work in relapsing MS.

The answer is here.

Schuh E, Berer K, Mulazzani M, Feil K, Meinl I, Lahm H, Krane M, Lange R, Pfannes K, Subklewe M, Gürkov R, Bradl M, Hohlfeld R, Kümpfel T, Meinl E, Krumbholz M. Features of Human CD3+CD20+ T Cells. J Immunol. 2016;197:1111-7. 


"These cells display a lower level of CD20 than B cells and lack markers typically found on B cells such as HLA-DR, CD40 and CD19".

"We sorted CD3+CD20+ cells, CD3+CD20 T cells, and CD19+CD20+ B cells from healthy donors to compare their transcript levels of CD3, CD19, and CD20 by quantitative PCR"......they got


Yep the same result, the CD20+ T cells are not going to be hit by CD19-depleting antibodies.

So can the effect of CD19 depleting antibodies be explained via a T cell mechanism?

Maybe its time to think that really CD20 works, because its depleting B cells.

Hunting for Treatments for Progressive MS.

There are a number of initiatives from the multiple sclerosis societies aiming to hunt and test for treatments for progressive MS.

People are screening public data bases to see if they can get ideas for candidates to test.

We will soon have the results of one of these approaches with the delivery of results from the United Kingdom MS-SMART study. This has tested the influence of fluoxitine (sertonin-reuptake inhibitor), riluzole (a glutamate receptor and ion channel blocker) and amiloride (an acid sensing ion channel blocker) in secondary progressive MS.

Fluoxetine was next on the list after Ibudilast but that was tested in the MS-SPRINT trial undertaken in the United States, which has also finished.

However, the MS Societies have not finished and they want to test more. 

So they need: 

(a) An optimum trial design to test the agents and 
(b) the agents.

The pharma approach is to innovate or to innovate to re-engineer existing targets to get a patent and then test.

The academic approach is to repurpose existing generic drugs.

Academia has found candidates should we give them a go?

Disease activation after abortion

We know that pregnancy reduces the risk of attacks.

Likewise we know that you are risk of attacks, after the baby has been born.

So what happens after an adorption?

Nerve transmitter receptor inhibits myelinating cell formation-Block it to get remyelination

The neurotransmitter acetyl choline binds to muscarinic receptors.


Clemastine  is a muscarinic receptor blocker and stimulates remyelination

Benztropine is remyelinating agent that is a muscarinic receptor blocker too. However, these are dirty drugs and bind to many things, meaning the potential for unwanted side effects.

There are five types of Muscarinic receptors M1-M5

Preventive Neurology

Avid readers of this blog will have probably noticed that Prof G has been increasingly focusing on new initiatives recently. One of these is Preventive Neurology - as part of this we have received a large grant to set up a Preventive Neurology Unit, based at the Wolfson Institute of Preventive Medicine within QMUL. 



But what does preventive neurology have to do with MS, given that we can’t even be sure as to the cause of MS? And how will this work?

Dear supporters 
Over the past month, we have presented MS Brain Health research at major conferences in Europe, the USA and Australia and learned more about the experiences of people living with MS in the USA. It has been great to meet some of you in person at these events, and we are pleased to welcome many new supporters!
Consensus standards presented at EAN 2018 
International consensus standards for the timing of key stages in MS care were presented in our focused workshop, Brain Health in MS: a catalyst for a new approach to management, at EAN 2018 in Lisbon this month. Over 150 attendees joined this interactive workshop and gave their responses to the new quality standards.
Professor Gavin Giovannoni, Dr Gisela Kobelt and Professor Jeremy Hobart gave presentations and participated in a lively Q&A session. "The standards should not be used as a means to criticize MS teams, but instead provide an opportunity for every MS clinic to strive for the highest level of care," stressed Professor Hobart.

Antibodies to PEG interferon may affect its action

Int Immunopharmacol. 2018 Jun 27;62:1-6. doi: 10.1016/j.intimp.2018.06.030. [Epub ahead of print]

Interaction of PEGylated interferon-beta with antibodies to recombinant interferon-beta.

Gilli F, De La Torre AL, Royce DB, Pachner AR.

Abstract


Because PEGylated molecules exhibit different physicochemical properties from those of the parent molecules, PEGylated interferonβ-1a (pegIFNβ-1a) may be able to be used with retained bioactivity in Multiple Sclerosis (MS) patients who have previously developed neutralizing antibodies (NABs) to recombinant interferonβ (rIFNβ). Hence, the objective of the present study was to test whether pegIFNβ-1a is less antigenic for NABs in vitro than rIFNβ. Two in vitro assays were used to quantitate NABs in 115 sera obtained from MS patients included in the INSIGHT study: the cytopathic effect (CPE) assay, and the MxA protein induction assay. NABs cross-reactivity was assessed by comparing dilutions of serum with fixed doses of rIFNβ-1a Avonex® and pegIFNβ-1a Plegridy®. NABs were shown to cross-react in both assays. The y-intercept (c), the slope of the line of agreement (b), the Pearson coefficients as well as the Bland-Altman analysis, indicated that there is good level of agreement between NAB titers against the two IFNβ-1a formulations, with both the CPE (c = 0.1044 ± 0.1305; b = 0.8438 ± 0.06654; r2 = 0.587; bias index ± SD = -0.01702 ± 0.6334), and the MxA protein induction (c = 0.08246 ± 0.1229; b = 0.8878 ± 0.06613; r2 = 0.615; bias index ± SD = -0.09965 ± 0.6467) assays. Until further in vivo evidence is established, clinicians should consider the current in vitro data demonstrating NAB cross-reactivity between pegIFNβ-1a and rIFNβ when discussing new treatment options with MS patients.

EBV in the brain

Epstein Barr Virus (EBV) is a herpes virus which is spread by saliva and infects around 95% of us during our lifetimes. In the majority of people EBV infection does not cause prominent symptoms - it may cause a ‘flu-like’ illness which gets better on its own, or it may go completely unnoticed.
