Inside An MS Exacerbation


By Devin Garlit · 

Exacerbation, relapse, flare-up, attack: these are all names for the same thing with regard to Multiple Sclerosis. The general definition of this event is the occurrence of new or worsening of old symptoms lasting for more than 24 hours and taking place at least 30 days after a similar event. While this can be standard occurrence for those with Multiple Sclerosis, not everyone actually understands what’s going during this period. Understanding what is happening during an exacerbation is critical for those with MS. With that in mind, I’ll do my best to help break it down as simply as I can.
What’s happening to the body during an MS exacerbation?
During one of these moments, the disease has caused your own immune system to attack your body. Specifically, your immune system begins to assault your central nervous system. Its weapon of choice? Inflammation (caused by various immune cells). This inflammation damages myelin, a fatty substance that surrounds and helps insulate our nerves. This insulating layer makes sure our nerves properly conduct the electrical signals that our brain sends to the other parts of our body (think of it as the plastic covering on an electrical wire). When this layer is damaged, those signals don’t move fast enough or at all, which is where we start to see our symptoms. Can’t lift your leg fast enough or at all? The myelin around a nerve between your brain and leg has been compromised and the signal isn’t traveling as efficiently as it should be. Not only does our immune system damage the myelin, but it also damages the cells needed to regrow it.
When the immune system attacks
These moments that we call exacerbations (or whichever term you like) are when the immune system is making its attack. It’s when the immune system has created a lot of inflammation in your central nervous system, and it’s damaging that myelin layer. Not only does this inflammation damage that protective coating, but it also has an effect on those signals that are traveling through that part of the central nervous system. We use steroids to fight exacerbations as they help to reduce this inflammation.
When a relapse is over: the aftermath
When an exacerbation is over, these damaged areas of myelin develop some scar tissue (that’s where we get the term sclerosis in multiple sclerosis, we are left with multiple scars; these scars are also referred to as plaques or lesions). Once all that inflammation is gone or significantly reduced, some of that myelin can regrow, but it never grows back completely or strong enough due to the scarring and because the cells needed to facilitate regrowth have been damaged. This regrowth, coupled with the reduction in inflammation, is why people can seem to bounce back after an exacerbation. They may even seem like they are completely well again. That’s why people often use the term “relapse,” because they seem to improve or go back to the way they were. This is a pattern that is extremely common in people diagnosed with the Relapsing-Remitting form of the disease. However, the more exacerbations you have, the more your ability to bounce back becomes hindered.
Accumulating damage over time
The more scars you have and the more cells that help regrow myelin are damaged, the less you are able to recover. In the past, maybe a damaged nerve could still get the brain’s signal where it needed to go, even if not the most efficiently (unless an outside influence temporarily triggered an issue). As more damage occurs over time though, the ability of that nerve to do its job, no matter the situation, becomes compromised. Basically, that’s how people with MS can worsen over time. That’s why doctors try to not only shorten the length of exacerbations through steroids, but to minimize the overall number of them with disease-modifying drugs.

New MS Research

Research on immune activity in MS

Understanding and stopping MS in its tracks requires a better understanding of the role that the immune system plays in this disease. This system is involved both in the inflammatory attacks on myelin and, very possibly, in the injury to axons (the wire-like nerve fibers) that contributes to longer-term disability. Research on the immune system includes studies on:
  • Understanding components of the immune system such as T cells, B cells, and antibodies
  • Identifying new targets for therapeutic intervention while leaving the rest of the immune system capable of fighting infections
  • Identifying substances and processes involved in the injury of axons
  • Identifying the body’s natural immune messenger molecules that can either turn on or turn off immune attacks
Significant progress is being made in understanding the immune system's involvement in MS, which will help drive breakthrough solutions to change the world for everyone with MS.

We’re making progress

Studies of the immune system in MS laid the groundwork for every disease-modifying therapy now available, and these studies continue to hold promise for finding ways to stop MS. Here are reports of recent progress:

Researchers co-funded by the National MS Society report study results indicating that “Tregs” – regulatory immune cells that are known to be dysfunctional in people with MS – play a role in promoting formation of new myelin following damage. If the results are confirmed through further research, these basic laboratory studies could eventually be translated to promising new therapeutic approaches to stimulating myelin repair to restore function in people with MS. Read more

Treatment with ATX-MS-1467 (Apitope) – an injected immune therapy whose early development was supported by the National MS Society through Fast Forward, the Society’s commercial research funding program – was reported to reduce disease activity on MRI scans in two small open-label studies involving people with relapsing MS. This is an approach to identify pieces of human proteins, called “peptides,” that might be able to reinstate “immune tolerance” – in effect, train immune cells to ignore myelin – to suppress MS attacks. Read more

Scientists at the University of Florida, funded in part by the National MS Society, took a novel approach to turn off immune attacks in mice with an MS-like disease. The team used a harmless virus to deliver a gene coding for a specific component of myelin, a key target of immune attacks in MS. Further research is needed to verify and refine this approach before it can be tested in people. Read more

Results Published from Trial of Siponimod in Secondary Progressive MS


  • Results of a 60-month, phase III clinical trial of the experimental oral therapy siponimod (BAF312, Novartis Pharmaceuticals AG) involving 1,651 people with secondary progressive MS have been published. The results were originally presented in September 2016 at the ECTRIMS conference.
  • The trial met its primary endpoint of reducing the risk of disability progression compared with inactive placebo. Those on active treatment had a 21% reduced risk of disability progression compared to those on placebo. Secondary endpoints suggested that those on active therapy had 23% lower average change in brain volume and reduced lesion volume. There was no significant difference seen between groups in the timed 25-foot walk.
  • The therapy was generally well tolerated and similar to adverse events reported for similar compounds. The serious adverse events reported to be more likely for those taking siponimod included nervous system disorders and infections.
  • Dr. Ludwig Kappos (University of Basel in Switzerland) and a large team of investigators report detailed results of the trial in The Lancet (online March 22, 2018). A commentary about the results by Drs. Luanne Metz and Wei-Qiau Liu (University of Calgary) is also published online.

DETAILS
Background: Siponimod (BAF312) is an experimental immune system-modulating therapy that was designed to be a more selective sphingosine 1-phosphate receptor modulator than Gilenya® (fingolimod, Novartis International AG). Gilenya, was approved in 2010 for adults with relapsing forms of MS to reduce the frequency of clinical relapses and to delay the accumulation of physical disability. Siponimod previously demonstrated safety and efficacy on MRI scans in a phase II study in people with relapsing-remitting MS (The Lancet Neurology, 2013 Aug;12(8):756-67).

Siponimod is thought to act by retaining certain white blood cells in the body’s lymph nodes, keeping them out of circulation and from entering the central nervous system. Siponimod also distributes effectively to the central nervous system (brain and spinal cord) where it may have direct anti-inflammatory or other effects.

The Study: Participants with secondary progressive MS were randomly assigned to take siponimod or placebo capsules daily for up to 60 months. The primary endpoint of the study was reducing the risk of disability progression, as measured by the EDSS scale that was sustained for at least 3 months. Secondary endpoints included reducing the risk of disability progression as measured by the EDSS at six months, the risk of worsening mobility as measured by the timed 25-foot walk test, disease activity as observed on MRI scans, relapse rate, and safety/tolerability.

Results: The results were originally presented in September 2016 at the ECTRIMS conference. The trial met its primary endpoint of reducing the risk of disability progression compared with inactive placebo. Those on active treatment had a 21% reduced risk of disability progression (confirmed at 3 months) compared to those on placebo. Secondary endpoints suggested that those on active therapy had a 23% lower average change in brain volume, and reduced MRI-detected brain lesion volume. There was no significant difference seen between groups in the timed 25-foot walk. Relapse rates were significantly lower in those taking siponimod.

Safety: The therapy was generally well tolerated and similar to adverse events reported for related compounds. Serious adverse events occurred in 16.7% of participants. The serious adverse events reported to be more likely for those taking siponimod included nervous system disorders and infections. More of those taking siponimod than the placebo experienced adverse events (89% vs 82% patients), such as a slower heart rate, high blood pressure, reduced white blood cell counts, macular oedema (swelling at the back of the eye), increased liver enzymes, and increased numbers of convulsions.

Dr. Ludwig Kappos (University of Basel in Switzerland) and a large team of investigators report detailed results of the trial in The Lancet (online March 22, 2018). A commentary about the results by Drs. Luanne Metz and Wei-Qiau Liu (University of Calgary) is also published online.

Comment: “While the magnitude of this response is somewhat modest, it represents a milestone in our unrelenting search for treatments that will benefit people living with progressive forms of MS,” said Bruce Bebo, PhD, Executive Vice President of Research at the National MS Society.

Australian Team Finds Possible Molecular Pathway for MS Progression

Researchers from Australia report that the amount of molecules in a sequence of chemical reactions called the kynurenine pathway differs between people with MS and healthy controls, and between people with relapsing-remitting and progressive forms of MS. The kynurenine pathway is activated by chronic inflammation, and its activation may be involved in nerve damage and MS progression.  The kynurenine pathway has also been implicated in other neurological and psychiatric disorders. The MS-specific findings, and the potential use of the kynurenine pathway in a diagnostic test, will need to be explored in additional studies.

This work was funded by the National Health and Medical Research Council and Multiple Sclerosis Research Australia. The researchers used several repositories to complete these experiments – the Accelerated Cure Project for MS, The Human Brain and Spinal Fluid Resource Center (which is sponsored by the National MS Society, among others), and the Tasmanian MS Longitudinal Study.

Two Small Studies Find Benefits of Exercise for People with MS with Moderate to Severe Problems with Movement

Summary
  • Two small studies report on the benefits of exercise for people with MS who have moderate to severe mobility impairments. This research shows the importance of physical activity in enabling people with all forms of MS to live their best lives.
  • The National MS Society provides resources on exercise for people living with all forms of MS, as well as for healthcare providers. Further information on increasing physical activity in adults with disabilities is available from the Centers for Disease Control.
Details
Background: Growing evidence suggests that exercise is good for a person’s overall health and for reducing other health conditions (co-morbidities).  Research in MS has also suggested that exercise training is effective for improving aerobic capacity and muscle strength, mobility, quality of life, and may benefit cognition, fatigue and depression. However, research is limited on exercise options for people with MS who have moderate or severe mobility impairments. Two recent, small studies begin to address this gap.

Exercise for severe mobility impairments: Investigators randomly assigned 12 people with progressive MS to receive total-body recumbent stepper training (similar to climbing stairs) or body weight–supported treadmill training. Both are used for people with severe mobility impairments, but the authors wanted to see if stepper training showed similar benefit to treadmill training, because it is significantly less costly to use and maintain the equipment. Participants completed three weekly 30-minute sessions for 12 weeks. Both training programs were safe, and although participants enjoyed both, stepper training was reviewed more favorably. There were no changes in physical function, but both reduced fatigue and improved quality of life.

The team (Lara A. Pilutti, PhD, now at the University of Ottawa, and former colleagues at the University of Illi­nois at Urbana-Champaign) has published results in the International Journal of MS Care (2016;18:221–229).

A cycling option for non-ambulatory people: Functional electrical stimulation (FES) offers people with significant weakness and mobility problems a cycling option, using low-level electrical impulses to stimulate the activation of leg muscles. Researchers evaluated whether this type of cycling improved symptoms and quality of life in 16 people with moderate to severe MS who were unable to walk. Participants cycled for 30 minutes, two to three times a week for one month. Significant improvements were noted in cycling performance, and physical and psychosocial aspects of fatigue, as well as reductions in reported pain. There were no significant changes in spasticity, cognitive aspects of fatigue, or muscle strength. Further research in larger numbers of people would help to clarify how benefits might be optimized.

The team (Deborah Backus, PhD, PT, and colleagues at the Shepherd Center, Atlanta, GA) report their results in the International Journal of MS Care (Published online, August 9, 2016).

New research strengthens genetics, MS link



In a large-scale, genome-wide analysis of more than 110,000 samples, researchers identified 200 genetic loci associated with multiple sclerosis. The study authors said that while the research highlights the role of several different immune cells that contribute to the initiation of this inflammatory disease, the mechanisms that lead this inflammatory disease to target the brain and spinal cord remain unclear.
By comparing the genomes of people with and without MS, the researchers identified 200 variants that were significantly more common among those with the disease. Most of these variants implicate genes that are associated with immune cells and immune system function, including a few potentially specific to brain-related functions.
Interestingly, many of the genes identified were known to also be involved in other autoimmune diseases, such as rheumatoid arthritis, Type I diabetes, and ulcerative colitis. This raises intriguing questions about why these diseases target different organs and have different clinical manifestations.
The findings were presented at the American Society of Human Genetics (ASHG) 2016 annual meeting in Vancouver, B.C.

Finding Solutions for the Advanced Care Needs of People with MS




While researchers are working to identify new and better strategies to stop MS, restore function and end MS forever, people whose MS has become more disabling—and their family members and friends—need information right now about how to manage the challenges they face. With these goals in mind, the National MS Society convened a group of key stakeholders – including people with MS, support partners, Society staff and clinicians from the fields of neurology, primary care, rehabilitation medicine, psychology, nursing, physical therapy and speech pathology– to help inform the Society’s role in finding solutions for individuals and families who are facing advanced care needs.    

“At the Society, when we face a challenge, we get the brightest minds together and put the problems on the table,” said Cyndi Zagieboylo, President & CEO of the National MS Society. “We need to pursue every opportunity to support people with advanced MS in living their best lives.”

What It’s Like

People living with MS lent a vital voice to the process. “It’s going to be very important as you think about this that you understand our lived experience,” urged Lisa Iezzoni, MD, a health services researcher who has MS. “It takes me about 10 times longer to do the most basic task.”
Karen Jackson, who lives with primary progressive MS, agreed. “Having advanced MS means I have lost the ability to be spontaneous,” she said. “I am forced to plan every minute of every day. The only thing more exhausting than planning my day, is not planning. It takes an annoying sequence of action steps to achieve even the smallest goal, like buying gas or parking the car.”

Resilience, however, rang through despite the challenges of advanced care needs, which for both of these women includes wheeled mobility. “When people ask me how I feel about my MS, I tell them that I’m not sick,” insisted Dr. Iezzoni. “I just can’t walk.” Ms. Jackson added, “Explain to people what your needs are. They want to help.” It’s worth the effort, she says. “Not participating in life is not an option.”

If I Have to Use a Wheelchair…
Getting a wheelchair was noted to be a “line in the sand” for many people living with MS, who often view the choice to use one as a loss of independence.  Meanwhile, by trying to stay on their feet, people might be curtailing activities because of increased fatigue, or concerns about stumbling or falling.

 “One of our challenges is that the wheelchair is used to symbolize disability,” said physical therapist Jean Minkel (Independence Care System. New York). “The wheelchair should not be considered a failure of therapy.”

Dr. Iezzoni heartily agrees. “When I finally started using a wheelchair 14 years after my first MS symptom, it was like spring after a housebound winter,” she said. “Silliness – that I was afraid people wouldn’t think I was strong because I was using a wheelchair.” Ms. Jackson agreed. “I’m learning to navigate a new normal,” she said. “My goal when I meet you is to have my chair disappear in 10 minutes, so that you only see me!”

Evaluating the home environment is key to determining the type of mobility device needed. “A picture is worth a thousand words and a home visit is a narrative,” said Ms. Minkel.  “To understand the need, we need to see the environment. For example, show me what the front door looks like.”

The wheeled device is not the only crucial factor – so is choosing the proper cushion to sit on. Some cushions can relieve pressure, thus preventing pressure sores (sites of damaged skin that can cause serious infections). “Thirty percent of our clients are at risk for pressure sores,” said Minkel. “Only two percent get them because they have pressure-relieving wheelchair cushions.”

The National MS Society provides guidance for people with MS and healthcare providers to navigate the process of choosing and obtaining coverage for a wheeled device. 

Finding Solutions
Participants considered other key issues related to the advanced care needs of people with MS, naming some difficult problems and suggesting solutions.

  • Breathing easier -- “Respiratory dysfunction begins very early in the disease process,” noted physical therapist Donna Fry, PhD (University of Michigan-Flint). But, she said, respiratory exercises can improve strength in respiratory muscles even late in the disease. Dr. Fry’s team has shown these improvements using “threshold inspiratory muscle trainers,” inexpensive devices that can help breathing muscles to get stronger. “Most clinicians are not aware of the potential early involvement of the respiratory system in people with MS and of accessible, inexpensive equipment that can enhance muscle strength,” she added. 
  • Muscle spasticity -- “Quite a few people with MS are experiencing significant problems from spasticity,” said neurologist Francois Bethoux, MD (Cleveland Clinic). Spasticity may be as mild as the feeling of tightness of muscles or may be so severe as to produce painful, uncontrollable spasms in the extremities, usually the legs. Dr. Bethoux believes spasticity can often be managed without specialized care. “Optimal care would involve an early diagnosis, setting realistic goals, and re-evaluation,” he said. Plus, stretching is vital, even if mobility is impaired

·         Swallowing -- “We all swallow 400-500 times a day, often without knowing,” said speech-language pathologist Alex Burnham (The Boston Home). “But 30-40% of people with MS can have problems with swallowing.” The consequences can be serious – breathing in food or fluids, choking, malnutrition, dehydration, and not taking medicine. Especially later in the disease, says Mr. Burnham, swallowing and feeding issues can have dramatic effects on quality of life, especially if it limits enjoying a meal with friends and family or prevents someone from eating favorite, culturally-significant foods. Mr. Burnham advocated for screening for these problems during regular visits. “Ask patients, have you had any trouble eating? Swallowing your pills?” Burnham also mentioned novel therapies that may prove helpful, such as the “free water protocol,” in which patients are allowed to have water by itself to improve hydration. Another method is neuromuscular electrical stimulation, applied in low doses to the neck
·         Speech -- Swallowing disorders can occur hand-in-hand with speech difficulties. “It’s never too early to start thinking about assistive technology, especially for people with a wide fluctuation of symptoms,” noted Mr. Burnham. “They might be fine in the morning, but then if they don’t get a nap, fatigue makes it hard for them to speak intelligibly later in the day.” Give people with MS an opportunity to use as many different modes of communication as possible, he advised. “Miscommunication can lead to frustration, social isolation, and a loss of independence,” said Mr. Burnham. “Maintaining any form of communication is critical for empowerment, relationships, and appropriate disease management.”  , including the use of smartphone applications.
·         Thinking and mood problems – “Cognitive changes are among the most prevalent reasons that people with MS are admitted to nursing homes,” said Rosalind Kalb, PhD, Vice President, Healthcare Information and Resources at the Society. “We need to be providing strategies to help people compensate for cognitive changes, and we need to speak to family members, since families may help to pick these changes up earlier.” With mood, it’s vital to understand that although depression in common in MS, some mood changes may be a natural consequence of the process of an advancing chronic disease. “People may be grieving over changes,” said Dr. Kalb. “We need to treat depression when it is present and also be respectful and comfortable with talking with people who are not depressed about how they want to live the rest of their lives.”

Achieving Optimal Care
The group discussed how to achieve optimal care for people with advanced MS.  Nicholas LaRocca, PhD, Vice President of Healthcare Delivery and Policy at the Society, noted that health care concerns are changing as the MS population gets older. “The average age of people with MS has increased by over 30 years since 1984,” he said. “Coexisting conditions, such as hypertension, increase with age and appear to be increasing in MS. Furthermore, people with MS who have some of these conditions at diagnosis reach the most severe level of mobility impairment faster than those who don’t.”

The group agreed that education is needed on both ends of this spectrum. Primary care providers need to be educated about MS so that they can distinguish MS symptoms from conditions that require primary care. And people with MS need to be educated about the importance of watching out for their own health. “A person with a disability still needs their cholesterol checked,” said Ms. Minkel. ”They still need their blood pressure checked.” Neurologists and primary care providers need to communicate, collaborate and coordinate their care of a person with MS.

Early and ongoing evaluation of symptoms also is key. “We need to educate people with MS and their caregivers about advocating for chronic care issues,” said Ruth Whitham, MD (Oregon Health& Science University). “Perhaps we can develop an advanced MS care checklist that would include symptoms to think about and what to do if you notice them.” The goal is to help people with MS to advocate for early and ongoing assessment, and for healthcare providers to ask routinely about changes that may be occurring throughout all bodily systems.
Importantly, people with MS need to know they have the right to advocate for care, regardless of how advanced their MS. “We don’t ever want a person to hear, ‘There’s nothing more we can do for you,’” added Dr. Kalb.
 
Caring for Caregivers
Speakers paid careful attention to how advanced care needs can affect caregivers.
“Families can become isolated,” said psychologist David Rintel, EdD, whose father lived with MS. “You feel pretty different from everyone else, and that isolation is harmful to your physical and mental health.” He advised that healthcare providers should see the caregiver occasionally along with the patient, if the patient grants permission, to get their perspective, and also see how the caregiver themselves are doing. “We need to learn the signs of burnout, such as depression, and increased use of alcohol,” he said. “Caregiver burden is real.”

There also is much that a caregiver needs to learn – navigating the healthcare system, how to transfer people safely, and management of bladder and bowel problems. “Dealing with bowel/bladder issues is actually a leading cause of caregiver burnout,” added nurse Cindy Walsh (The Boston Home).

 “Families have to learn how to ask for help,” said Dr. Rintel. “They have to ask in a way where they say what, where, when and how long. Most people would help if they understood specifically what you need.”

Next Steps
The group identified the highest priority research questions that need to be answered concerning the care and support of people with advanced care needs and their families, pinpointing questions in the areas of assistive technology; comorbidities and primary care; health care system issues (e.g., insurance coverage); long-term care; symptoms and complications; skin care; speech, swallowing, and pulmonary functions; and the benefits of wellness/lifestyle interventions. They are now formulating a prioritized list of these questions to help inform the Society’s next steps.

A white paper describing the meeting’s discussion highlights and recommendations regarding the Society’s response to the needs of those affected by advanced MS will be posted on the Society’s web site, and a similar paper will be submitted for publication in a peer-reviewed journal.
