Make Visible: Chronic Illness Explored

#14. Wearable technology and patient-led innovation with Dr. David Putrino

Data gathered from wearable technology can warn of impending symptom exacerbation in complex chronic illness a new study has found.
In this week’s episode Dr. David Putrino discusses the findings.  He, in collaboration with leading immunologists, microbiologists and data scientists, tracked data points from 5000 Visible app users (who enrolled in the study) to establish that HRV and resting heart rate can be used to predict a crash.  Analyzing more than 55,000 readings over 1000 days they were able to see changes in the autonomic nervous system of contributors using this biometric data.  The largest study of its kind, these findings have the potential to provide the basis for individualised care strategies for this enormous cohort of patients.
Here we discuss the function and dysfunction of the autonomic nervous system.  Dr. Putrino gives us an overview of heart rate variability, the way in which it fluctuates, what its readings can determine about our health and ways in which these can be influenced. We talk through the power of breathwork including two of Dr Putrino’s studies – on resonant breathing and hypocapnia – showing the way in which breathing impacts our physiology but determining that we have innate power to influence our health.
As Director of Rehabilitation Innovation Mount Sinai Health, Dr. Putrino‘s focus is on real-world solutions for this patient cohort. In a world where new drug approval takes 10 years and technologies in this field can take 17 years to reach market, his aim is to bring patients tangible treatments and protocols in a practical timeframe. Currently involved in clinical trials for rapamycin and vagal nerve stimulation, Dr. Putrino endeavours to re-purpose drugs and technologies that are already approved in other situations to create personalised strategies for this engaged cohort.

#13 The role of Mast Cells in complex illness: what they are and how to calm them with Dr. Theoharis Theoharides

Dr. Theoharis Theoharides ‘The Mast Cell Master’ has been at the forefront of mast cell research for over 30 years. A renowned expert in allergy, neuroinflammation, and mast cell biology, his work centers on understanding the regulation of these critical immune cells. His extensive studies explore their fundamental role in the body, the mechanisms behind their activation and inhibition, and their involvement in a wide range of conditions—from asthma and eczema to neuroinflammatory disorders and complex chronic illnesses.
In this week’s episode, we delve into the role of mast cells in complex chronic disease. Dr. Theoharides explains how mast cells are distributed throughout the body, the various stressors that can activate them, and how their activation may contribute to overlapping symptoms seen in conditions such as migraines and irritable bowel syndrome. The comparisons draw into question whether a degree of mast cell activation is co-morbid in many of these conditions, or indeed whether some of these conditions are a symptom of mast cell activation.
He underscores the urgent need for better diagnostic tools, greater awareness within the medical community, and a broader, more integrative treatment strategy. This includes lifestyle interventions and the use of natural flavonoids, which have been proven to inhibit mast cell activity. Dr. Theoharides also discusses the ongoing challenges in securing research funding and the potential for integrative approaches to address complex conditions – thinking outside the box to treat patients individually, listening to their needs and treating accordingly – which is what he believes they are able to do with his team at NSU
Dr. Theoharides is Executive Director, Center of Excellence for Neuroinflammation Research (CENIR) & Professor, Institute for Neuro-Immune Medicine at Nova Southeastern University.  Prior to this he spent four decades at Tufts University where he was Director of Molecular Immunopharmacology & Drug Discovery.

#12 "Chronic Overlapping Pain Conditions" in ME/CFS, new insights with the C.D.C’s Dr Elizabeth Unger, Yang Chen & Elizabeth Fall

The U.S.A.’s Centre for Disease Control (C.D.C) ME/CFS program has been working for decades to deepen our understanding of the condition. Their Multi-site Clinical Assessment of ME/CFS (MCAM) study, conducted across seven specialized clinics in the U.S. from 2012 to 2020, provides valuable data that forms the foundation for ongoing research. 
Dr Elizabeth Unger, chief of Chronic Viral Diseases Branch, and epidemiologists Yang Chen and Elizabeth Fall, have contributed to numerous studies exploring various aspects of ME/CFS, from cognitive impacts to looking for biomarkers. In this episode, we focus on their latest paper, which examines the prevalence of Chronic Overlapping Pain Conditions (COPCs) that occur in ME/CFS.
Three-quarters of ME/CFS patients suffer from COPCs (defined as: Chronic low back pain; Chronic migraine/Headache; Fibromyaligia; Endometriosis; Interstitial cystitis/Irritable bladder; Irritable bowel syndrome (IBS); Temporomandibular disorder (TMD); Vulvodynia) with women being more likely to experience at least one of these co-occurring conditions.  The understanding of why these are so prevalent in ME/CFS is the next piece of the puzzle.
A large portion of this team’s work is educating patients and carers along with healthcare workers.  They are immensely proud of their resources such as their patient tool kit, management strategies and disability advice, tailored to helping patients advocate for themselves and their family members to receive appropriate diagnosis, treatment and care.  Sitting alongside this is a section for healthcare providers where they present a clinical overview to assist in the diagnosis and care, with a toolkit containing many educational and reference resources.
The MCAM data and biospecimens are also available (via application) to other investigators to maximise the impact of this longitudinal study.

#11 Post-Pandemic prevalence of ME/CFS - what we can learn from the increase with Suzanne Vernon, PhD

In her latest paper Suzanne Vernon, PhD, Scientific Director at the Bateman Horne Center, reveals that ME/CFS prevalence is now 15 times higher than pre-pandemic estimates.
The study, carried out by the RECOVER initiative, and published in the Journal of General Internal Medicine confirmed that ME/CFS has a 4.5% prevalence among those who did not recover from COVID-19, and forms the most severe subtype of Long Covid.  Whilst not all Long Covid patients will fulfil the criteria for ME/CFS, the ability to study the conditions in parallel and at the point at which they cross over is bringing us unprecedented insights into long term energy-limiting conditions.
 
In this week’s interview Dr Vernon highlights the challenges in identifying definitive biomarkers for ME/CFS due to its heterogeneity and the fact that there are multiple triggers, but explains how the longitudinal data gathered in the RECOVER study is making roads into understanding the pathogenesis and necessary treatments for ME/CFS.  This is due to one crucial factor: here we are presented with a huge group of ME/CFS patients who have developed the illness from one trigger, SARS-COV2.
Whilst the findings are shocking, and the stark quantity of people with ME/CFS is rising dramatically, Dr Vernon is positive about the way in which we can optimize this moment in time, with the research attention and funding in place, to reveal what is causing ME/CFS and then go on to work out how it can be treated.
Dr Vernon has more than 30 years’ experience in researching chronic illnesses, authoring hundreds of papers on the subject, working with the government and non-profits to move the needle in this research arena.  She is dedicated to understanding what drives conditions such as ME/CFS, whilst advocating for greater involvement amongst the scientific and medical communities.  Formerly the Scientific Director at  Solve ME/CFS Initiative, Dr Vernon is tireless in her bid to advance research, educate and improve care for those impacted by ME/CFS.

#10 Staying connected (Part 2): Dealing with isolation and limitations in complex illness with Suzy Bolt

When Suzy Bolt developed Long Covid in 2020 she searched for ways to understand her condition and began to create an online community of like-minded people traversing similar health situations. From her dark bedroom she found many others looking for answers, validation and ideas to help them navigate their illnesses, and from this she started to develop her holistic program.
Drawing on her background in counselling, yoga and neuro-linguistic programming - alongside her own experience of illness - Suzy launched an online platform in September 2020 to help people with post-viral and energy-limiting conditions. Her Rest, Repair, Recover program provides a space for support, community, and a deeper understanding of the nervous system.
The program brings together practitioners with lived experience of these conditions, offering an interactive framework of movement, breathwork, creativity, and rest - all aimed at regulating the autonomic nervous system.
In this two-part conversation, Bolt explores the cascade effect of small, positive changes—finding joy, building community, and practicing self-compassion—and how these shifts can influence the nervous system, immune function, and overall well-being.
In this, the second part of the conversation, we discuss the kindness, creativity and distraction from symptoms; along with nutrition, celebrating progress and the effect that these programmes have had on people’s lives.
Over the past five years Suzy Bolt has become a mainstay for those looking to improve their condition through a holistic approach. In a recent survey of those who have attended her programmes, the majority said that it improved their overall energy levels, improved their mood, alleviated some of their medical concerns and gave people confidence to manage their symptoms. She is regularly consulted and recommended by the NHS as an additional strand to medical help that people may be being offered.
Her approach endeavours to address autonomic dysfunction as a way to create optimum environment in which people can start to feel improvements in their health.

#8 Exploring the drivers of post-infectious illness, with Harvard Neuroimmunologist Michael VanElzakker, PhD

Dr. Michael VanElzakker’s mission is to identify the individual drivers of post-viral illnesses. “How do you find something when you don’t know what you’re looking for?” he asks, believing that COVID-19, whilst a disaster for humanity, is giving us the opportunity to establish practises to identify those unknowns and establish more unbiased research methodologies.
Whilst ME/CFS encompasses huge numbers of people who have a shared end point in their symptom sets, VanElzakker believes that we need to seize this moment of Long Covid - where we know what the pathogenic driver is - to develop our understanding and testing across these post-infectious conditions.
The juncture of the brain and the immune systems is the focus of VanElzakker’s work where he studies the drivers of chronic disease. Assistant Professor at Harvard Medical School, Massachusets General Hospital , and instructor at Tufts University, VanElzakker is a researcher, educator and patient advocate, taking a holistic approach to the science of his field.
Until 2020, VanElzakker focused his research on PTSD and ME/CFS, studying the interplay between the immune and nervous systems in these conditions. Drawing on this expertise in post-viral illnesses and the long-term effects of immune and nervous system dysregulation—whether triggered by a single event or persistent stimulation—he co-founded The PolyBio Research Foundation with the brilliant Amy Proal. Together, they have established a cutting-edge research initiative that brings together top scientists to develop a deeper, more cohesive understanding of these complex diseases.
In this episode VanElzakker shares insights into his research and the challenges surrounding chronic illness healthcare. He points to the need for improved testing protocols in ME/CFS to enable patients to rule out or identify underlying triggers for symptoms which have the potential to be addressed. He explains the differences that he has seen between the conditions of pre-Covid ME/CFS and the chronic consequences of COVID-19 in Long Covid patients. And he highlights PolyBio’s strategy of using the impetus and funding that has been brought to the fore to grapple with the millions of people suffering from Post-Covid conditions, to gain deeper understanding of post-viral conditions at large with the intention of moving other post-viral patients, from ME/CFS to post-Lyme, into studies as soon as is viable.

#7 Discovering new treatments for Brain Fog with Yale M.D. Arman Fesharaki-Zadeh

Arman Fesharaki-Zadeh is a behavioural neurologist and a neuropscychiatrist whose primary focus has been treating patients with cognitive deficits – from Alzheimer’s to Traumatic Brain Injury (TBI).  Since 2020 a considerable portion of his clinic at Yale Medicine have been Long Covid patients and he noticed similarities in symptoms with post-concussive syndrome and other neuroinflammatory conditions.
Working with Professor Amy Arnsten (and referenced in our previous episode), Dr Fesharaki-Zadeh has developed a treatment regimen using Guanfacine and N-acetylcysteine that he found to be effective in improving prefrontal cortical function in TBI.  Taking their knowledge from these patients and applying it to the treatment of the brain fog experienced by Long Covid patients, Fesharaki-Zadeh started using the same protocol and anecdotally it has had considerable impact in improving cognitive symptoms, emotional regulation, and even sleep.
Dr Fesharaki-Zadeh is pursing more empirical evidence, pushing for clinical trials to look at this treatment protocol.  His rationale for the treatment of cognitive deficits in Long Covid seems sensible and his proposed strategy is proven safe.
This conversation discusses the need for validating patients’ experiences by providing physiological understanding of their symptoms, the importance of expanding access to effective treatments for Long Covid and other conditions, and emphasizes the dynamic and interactive nature of the brain and the importance of considering it as part of the whole network rather than an isolated entity.

#6 The Science of Stress: Exploring Brain Function, Inflammation, and Cognitive Health with Yale Prof. Amy Arnsten

Amy Arnsten, PhD, is a Professor of both Neuroscience and Psychology at Yale University, where she runs her own lab which studies and teaches about the brain’s higher cortical circuits and their molecular regulation.
In this week’s episode we discuss Prof. Arnsten’s recent paper published in Biological Psychiatry looking at the impact of stress (both physical and mental) and inflammation on the prefrontal cortex, an area of the brain with implications in a range of conditions from depression and schizophrenia, to Alzheimer's and Long Covid.
Arnsten explains how she and her lab are able to observe the biological changes that take place in the brain when under chronic stress, or triggered by inflammation, which can lead to a primitive survival response: shutting down higher cognitive functions.  This area of the brain is responsible for the regulation of our emotions, our mood and our behaviour.  Changes in this region lead to the brain fog, memory issues and emotional dysregulation that is prevalent in these disorders.
And she talks us through the pathway of kynurenic acid production, levels of which are elevated in conditions such as Long Covid which inhibits neurotransmission.  The understanding of this could lead to break-throughs in our diagnosis and treatment of such conditions.  And Prof. Arnsten is already seeing promising potential with guanfacine, a compound that her lab developed for the treatment of ADHD (approved by the FDA in 2009).  A combination of guanfacine, which strengthens connections in the prefrontal cortex, with the anti-inflammatory, antioxidant supplement NAC (N-acetyl cysteine) seems to show possible beneficial applications in Long Covid.

#5 How our understanding of ME/CFS, fatigue and pain has progressed over the past decade with Lucinda Bateman M.D.

Lucinda Bateman, M.D. has been seeing patients, learning about, and educating about ME/CFS and fibromyalgia for decades. She is Chief Medical Officer of the Bateman Horne Center, Salt Lake City, whose mission is “improving access to informed health care for individuals with ME/CFS, Long COVID, and fibromyalgia by translating clinical expertise into medical education and research initiatives”.
Dr. Bateman was one of the researchers responsible for the National Academy of Medicine’s 2015 report on ME/CFS, a seminal paper that helped define the diagnostic criteria for ME / CFS.  Since then she has authored innumerable papers, working with the CDC alongside many of the stalwarts of the chronic illness medical community as part of the longitudinal multi-centre (MCAM) research that has looked at the impact, treatment protocols and drivers of ME/CFS.
A member of the ME/CFS Clinican Coalition, she is dedicated to advancing understanding of these chronic conditions and improving care and outcomes for patients.  Her work has found many benefits from treating co-morbidities in chronic illness, such as POTS, with her most recent publication addressing chronic overlapping pain conditions, including fibromyaligia, that are regularly found alongside ME/CFS.
And since the inception of Long Covid her work has pivoted to include this new heterogenious group of post-infection patients.  Much of her recent work has been looking at the parallels and differences between these illnesses and applying her historic knowledge to this new disease: she is one of the ME/CFS and Long Covid specialists working with the NIH on the RECOVER program. And her deep understanding of post- exertional malaise once again highlights the importance of pacing across these conditions
Her work over the decades has been tireless to developing understanding of, and treatment paradigms for, chronic post-infectious syndromes.
