Primer for the public

Primer for the public offers a broad audience detailed information on myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS), complex, chronic, and poorly understood medical conditions. ME was first categorized as a neurological disease by the World Health Organization (WHO) in 1969. CFS was first formally defined by the United States Centers for Disease Control and Prevention (CDC) in 1988 as a framework for researching unexplained chronic fatigue associated with a mononucleosis-like syndrome. There remains a lack of consensus among members of the medical and research communities regarding the equivalence of ME and CFS. Some believe that CFS is intended to describe the same disease entity as ME, while others believe that they are distinct conditions but with overlapping symptom profiles. In deference to this lack of consensus, the combined term 'ME/CFS is often used.

The acronym ME/CFS is widely used in research, by research and patient organizations, and patients. "The most common overlapping condition with ME/CFS is fibromyalgia."

The core ME/CFS symptoms are: chronic fatigue (CF); post-exertional malaise (PEM); unrefreshing sleep; and cognitive impairment or orthostatic intolerance (OI). A patient can have many more symptoms and meet different criteria. Systemic Exertion Intolerance Disease (SEID), an ME/CFS criteria, allows for a patient to be diagnosed with the minimum core symptoms. The Canadian Consensus Criteria (CCC) requires neurological, gastrointestinal, immune system, and other symptoms to meet its ME/CFS diagnostic criteria. The International Consensus Criteria (ICC) is used to diagnose ME which requires more neurological, gastrointestinal, and immune system symptoms for a diagnosis. Although Fukuda and the Oxford Criteria are used for diagnosing CFS, they are both overly broad and there is a problem with patients experiencing CF due to other diseases, illnesses, and depression and they are being diagnosed with CFS; this can happen in clinical and research settings.

Disease onset and course of illness
The disease ME/CFS is diagnosed when a person does not recover from a flu-like illness, EBV, mononucleosis, HHV, Q fever, virus or other infections and meets one or more diagnostic criteria for either ME, CFS or ME/CFS. "Occasionally, ME/CFS has been triggered by environmental toxins, the receipt of an immunizing injection, or surviving a major trauma." Patient health is never the same and they experience numerous symptoms and disease severity, which fluctuate day to day, week to week, month to month, year to year and decade to decade, as well as varying symptoms and disease severity among patients.

What happens when you have a disease doctors can't diagnose By Jen Brea/TED

https://www.youtube.com/watch?v=Fb3yp4uJhq0

Five years ago, TED Fellow Jen Brea became progressively ill with myalgic encephalomyelitis, commonly known as chronic fatigue syndrome, a debilitating illness that severely impairs normal activities and on bad days makes even the rustling of bed sheets unbearable. In this poignant talk, Brea describes the obstacles she's encountered in seeking treatment for her condition, whose root causes and physical effects we don't fully understand, as well as her mission to document through film the lives of patients that medicine struggles to treat.

Invisible Illness - Stories of Chronic Fatigue Syndrome By Veronica Weber/Palo Alto Onlinehttps://www.youtube.com/watch?v=9_HwOUiImvw

This mini documentary reveals 3 stories of people who have been impacted by Chronic Fatigue Syndrome - a little known disease that affects roughly 836,000-2.5 million people in the U.S. and receives little research funding. They share emotions of treating loved ones with the disease, their frustrations of being ignored by members of society and the healthcare industry and express hopes of treatment and research.

Epidemiology

 * Epidemiology
 * Female predominant diseases
 * Like many autoimmune and neuro-immune diseases where mostly women are afflicted, the ME/CFS female/male patient ratio is 6:1.


 * Pediatric
 * Prognosis
 * Prevalence
 * "An estimated 17-20 million people suffer from ME/CFS worldwide, and 25% of them have a very severe form of it." The 25% of patients who are severely ill are either bed-bound, wheelchair bound, or are housebound or nearly so. The ME/CFS Severely Ill, Big Data Study is focused on this 25%.


 * All races and cultures are afflicted with ME/CFS. Children and adolescents are also diagnosed.

United States In the United States, 836,000 - 2.5 million people suffer from ME/CFS. "The total economic costs of ME/CFS are estimated at $17 to $24 billion annually." Some CFS patients can work with job accommodations but 1/3 to 1/2 become unemployed and many rely on SSDI/SSI.

Symptoms
Symptom presentation varies enormously between individuals. Symptom presentation also varies within individuals, as individuals often report that symptoms change over time (increasing or decreasing) and new symptoms may appear while others disappear. There are many symptoms which people with ME/CFS experience, though those listed below are arguably the most common: "This is a term which describes a symptom in which exercise or exertion can bring on malaise (illness). In the case of people with ME/CFS, malaise often occurs during a period some 24-72 hours after exertion. For example, in some cases, a short walk can worsen ME/CFS symptoms two days later. This lack of understanding about the delayed onset of symptoms has, in the past, made it harder to test for ME/CFS. Follow up tests, taken less than 24 hours after an initial exercise test, may show that the patient can still perform activities at the same level (before post exertional malaise has a chance to take hold)."
 * Post-exertional malaise (PEM) is the hallmark symptom of ME/CFS. After physical or mental exertion (which for some patients can be a shower or making out a to-do list, others grocery shopping, socializing or reading a news article, while some just walking to the mailbox, getting to the doctor or mentally following a T.V. program)  there is a payback of worsening ME/CFS symptoms which can be delayed 24-72 hours or more  and can last 24 hours or more. The patient will experience even greater fatigue as well as exasperate the flu-like symptoms and body pain. Every patient experiences different symptoms and symptom severity from different activities and exertion output according to how sick he or she is with the disease.   Regarding PEM the CFIDS Association of America states:
 * Chronic fatigue
 * Cognitive dysfunction
 * Orthostatic intolerance, such as postural orthostatic tachycardia syndrome (POTS) or neurally mediated hypotension (NMH)
 * Unrefreshing sleep, and sleep disturbance

Other possible symptoms

 * Chronic pain is a mandatory symptom in the Canadian Consensus Criteria.
 * Neurological signs and symptoms (Category on MEpedia). Also, see: Neurological impairments in International Consensus Criteria and neuroinflammation.

Drugs, treatments and therapies
There are currently no Food and Drug Administration (FDA) approved treatments for ME/CFS. Treatments consist mostly of symptom management, rather than treatment of the underlying cause of the condition, which is not yet understood. There are many potential treatments, though their evidence base is limited, as most research into treatments has gone into unsuccessful psychological approaches to treatment.

Drugs
Two treatments that have garnered much attention are Ampligen, produced by Hemispherx Biopharma, and Rituximab. Many people have reported enormous benefit from Ampligen; some doctors have been prescribing it for ME/CFS for decades. Attempts to obtain FDA approval for Ampligen in the US have failed so it is unavailable to many. Argentina has approved the use of Ampligen in 2016. Also in 2016, it was made available on a limited basis in Europe. July of 2018, Hemispherx Biopharma, Inc "announced the immediate expansion of its Treatment Protocol/Expanded Access Programs for ME/CFS in the United States, known as AMP-511, to new enrollees for the first time in more than a year."

Rituximab, a lymphoma drug, had shown promising results in initial trials in Norway, and there were groups crowdsourced funding for further trials in other countries. On Nov 21, 2017, Drs. Øystein Fluge and Olav Mella announced that their Rituximab trial had failed. They stated that they would focus their efforts on attempting to identify a subgroup of ME/CFS patients with an immune profile that would be responsive to Rituximab. The doctors will publish a paper next year with the specifics of the failed trial.

Jarred Younger announced in March 2016 that he will be undertaking a trial of low dose naltrexone (LDN) in ME/CFS.

Controversy
Psychiatry has taken an inappropriate lead and treatment path for a biological disease. In the UK, graded exercise therapy (GET) and cognitive behavioral therapy (CBT) are employed by ME Clinics. Exercise exacerbates symptoms and can further injure patients. Depression and anxiety drugs are utilized usually with poor and even damaging results.

Treating a biological disease as a mental illness is cost. The drugs are inexpensive and biomedical research is not pursued. People struck down and disabled with ME/CFS are labeled with a mental health issue; disability insurance having clauses excluding a mental health illness/disease kick in stopping any payment or shortening the payout time-frame.

Graded exercise therapy & Cognitive behavioral therapy
GET and CBT are usually employed in the UK, Ireland and some parts of Europe through ME Clinics. They are highly controversial and not recommended by patients, most patient advocates, and research organizations nor by many doctors or researchers outside of the UK. Based on the flawed PACE trial which used the flawed Oxford criteria to diagnose and recruit patients, GET and CBT found its way into treating people with ME/CFS.

Exercise, especially GET, can injure an ME/CFS patient further.


 * Jennifer Brea walked home from her Neurologist's office and became wheelchair bound.
 * This is an experience of serious injury due to GET shared by K. Miles, via Tom Kindlon on Twitter.
 * Emma Shorter was able to walk a few minutes a day until GET put her in a wheelchair.
 * Doctor Speedy was also seriously injured by GET.

Claims of curative treatments
Charlatans claim they can cure CFS (per the CDC "there is no cure" ) when in reality they may be able to treat chronic fatigue (CF). Some people misdiagnosed and "recovered" from CFS may have had CF, which can be caused by many illnesses, diseases, and drug therapies or a bad year or two perhaps with mononucleosis followed by a bout or two of influenza. These individuals were experiencing a proper immune response, whereas ME/CFS patients experience an ongoing improper immune response and other abnormalities for at least 6 months straight with a reduction in activity with a specific symptom set for at least 50% of the time.

Additionally, some athletes diagnosed with CFS that recovered were actually suffering from overtraining syndrome, a condition they sometimes acquire, while some people with adrenal fatigue are sometimes diagnosed with CFS.

Working with government to move forward
Advocates met with senate staffers the week of March 16, 2016, and discussed research and drug development by the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC) reinstating and increasing funding and education based on Institute of Medicine report recommendations and the Health and Human Services (HHS) funding to develop Centers of Excellence. #MEAction reports on this ongoing process.

CDC Website updates

 * Jul 3, 2017, the CDC's Chronic Fatigue Syndrome page has been changed to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and GET and CBT recommendations have been removed.


 * Jul 12, 2018, the "Information for Healthcare Providers" tab and its sub-tabs were updated.

MEAction input
 * Jul 29, 2018, CDC Revises its Information on ME #MEAction report on the CDC July 2017 and July 2018 website updates. Recommendations for the CDC's ME/CFS page have been created from patient feedback on the updates as well as asking for further patient input.

Disease names and acronyms around the world
The United States and Australia usually refer to the disease as CFS, (chronic fatigue syndrome). Many European countries, the United Kingdom and Ireland mostly use the name ME, (Myalgic Encephalomyelitis). Most countries, as well as doctors and researchers worldwide, will also use the acronym ME/CFS and a few CFS/ME. See: Definitions of ME and CFS.

The symptom chronic fatigue (CF) should not be used in place of the name chronic fatigue syndrome (CFS); this has been a source of confusion of CF the symptom and CFS the disease. CFS is a grossly misnamed disease whereas CF is a symptom of many diseases, illnesses and drug therapies. Dr. Jarred Younger explains chronic fatigue and begins by stating "Fatigue is not a disease and it is not even a symptom. So fatigue is a alarm system and the most general alarm system the body has." Webinar with Jarred Younger, Ph.D. (@6:04-7:54)

Myalgic Encephalomyelitis (ME)
Although many similar diseases have occurred for centuries, in the 1920s - 1940s there were sporadic outbreaks around the world, of both poliomyelitis, and what Dr. Melvin Ramsay called 'Benign Myalgic Encephalomyelitis' ('benign because it is disabling but not usually fatal). In 1969, the World Health Organisation included "Myalgic Encephalitis' in its 'International Classification of Diseases' (ICD), under the category 'Diseases of the Nervous System', code G93.3.

From ME to CFS
Incline Village, Lake Tahoe, NV, USA experienced an outbreak during 1984-1985. The CDC were sent to investigate. Dr. Anthony Komaroff studied cases from the outbreak and eventually he and a body of clinicians settled on the name "Chronic Fatigue Syndrome". Dr. Komaroff discusses the name emerging in the documentary film Forgotten Plague.

From CFS to 'any unexplained fatigue'
Various groups invented new definitions, that required only 'medically unexplained fatigue' such as Reeves criteria and Oxford criteria. Fatigue is a common symptom in any population, with many different causes. These new definitions allowed some psychiatrists to claim that CFS could be 'cured' through exercise and positive thinking which has been promoted through the PACE trial and that this 'cure' also applied to people who are severely ill with Myalgic Encephalomyelitis. Postviral fatigue syndrome (PVFS) is the next frontier of the psychological paradigm keeping control of an organic disease and have been laying groundwork to do so.

SEID name and diagnostic criteria
Systemic Exertion Intolerance Disease (SEID) is a diagnostic criteria proposed by the Institute of Medicine (IOM) in the Institute of Medicine report. This clinical criteria was developed for doctors in the United States to diagnose at 6 months instead of years or even decades. Doctors are encouraged to perform tests prior to six months, such as a Tilt table test or sleep study if symptoms require further investigation. Treating symptoms such as orthostatic intolerance or a sleep disorder can begin prior to the six months needed to diagnose.

Currently used

 * Canadian Consensus Criteria (CCC)
 * Fukuda criteria (Sometimes referred to as CDC Criteria)
 * International Consensus Criteria (ICC)
 * Oxford criteria
 * Reeves criteria (Sometimes called Empirical definition)
 * SEID or IOM 2015 (Used by CDC on their ME/CFS Diagnostic Criteria for Healthcare providers page.)

Currently not in use

 * Holmes criteria
 * London criteria
 * Nightingale definition
 * NIOF
 * Ramsay definition

The different criteria used from one doctor to another and researcher to researcher results in confusion for doctors trying to diagnose, poor research and discord between patients, medical professionals, and charitable organizations. Adding to the confusion is a clinical criteria will at times be used in research and a research criteria used by a clinician to diagnose. Many US researchers will use Fukuda (using the PEM "option") and CCC in a single research project. The NIH Post-Infectious ME/CFS Study will be using four: SEID, Fukuda, CCC and Reeves. The ME/CFS community wanted to participate in this study's design.
