Myalgic encephalomyelitis/he

מתוך MEpedia

Myalgic Encephalomyelitis (ME) is a chronic, inflammatory, physically and neurological and immune-mediated disease that presents with symptoms involving multiple bodily systems. It is frequently triggered by a viral infection or a flu-like illness.[1] ME presents with symptoms in the central nervous system (CNS), autonomic nervous system (ANS), immune system, cardiovascular system, endocrine system, digestive system, and musculoskeletal system.[2][3]

Myalgic encephalomyelitis was first classified as a neurological disease by the World Health Organization (WHO) in 1969, with the publication of the ICD-8 manual.[4]

ME has occurred in both epidemic and sporadic forms.

The hallmark symptom of myalglc encephalomyelitis is post-exertional malaise (PEM), which is the result of intolerance to previously achievable cognitive or physical exertion.[5][6][7][8] Other key symptoms include muscle weakness and easy muscle fatigability, sleep disturbance, and cognitive dysfunction. ANS dysfunction is frequent, although specific symptoms vary from patient to patient and may include postural orthostatic tachycardia (POTS), reduced heart rate variability at night, and both cold and heat intolerance. Other common symptoms include myalgia (muscle pain), neuralgia (neuropathic pain), neck and spine stiffness, and sensory symptoms including sensitivity to light, sound, touch, paraesthesia (skin tingling or numbness) and hyperaesthesia (skin sensitivity and pain, and allodynia). There is a progressive form of ME, but it is rarer than the relapsing-remitting type.[9]

Among adults, ME is more common in women than men.[10] New onset has been observed in children[11] and in adults usually between the ages of 40-60.[12] Bakken et. al notes two age peaks for CFS/ME; age group 10 to 19 years and a second peak in the age group 30 to 39 years.[13]

There are no approved pharmacological treatments for ME anywhere in the world except in Argentina, which has approved the immunomodulator Ampligen for severe ME/CFS as of August 23, 2016.[14]

History[עריכה | עריכת קוד מקור]

Myalgic encephalomyelitis was first classified as a neurological disease by the World Health Organization in 1969, with the publication of the ICD-8 manual.[4]

Hillary Johnson is an American journalist and while ill herself, wrote the book Osler's Web which is the historical account of the early years of a "new" illness that had an outbreak at Incline Village which she shared the same symptoms. The illness came to be known as chronic fatigue syndrome (CFS). Johnson spent nine years investigating the outbreak and the CDC's refusal to acknowledge a devastating disease (deeming sufferers of Incline Village as having "mass hysteria") that can be spread through casual contact. She appears in the documentary Forgotten Plague and currently writes at Oslersweb.com

The ICD-8 did not include any alternative names for myalgic encephalomyelitis although postinfectious encephalomyelitis and all other encephalomyelitis diseases were classified under the same code; fatigue-related alternative names were not added in any later revisions.[4][15] The alternative name chronic fatigue syndrome (CFS) was not in use at this time; it was proposed in 1987 by the Centers for Disease Control, which adopted new diagnostic criteria the following year.[16]:29

In the ICD-9, which was published in 1989, the entry for myalglc encephalomyelitis is uses code 323.9:[17]

דף תוכן : History of myalgic encephalomyelitis and chronic fatigue syndrome

ME has occurred in both epidemic and sporadic form since at least the 1930s, although it has likely been occurring much longer but was not formally named. The first recorded outbreak of epidemic myalgic encephalomyelitis was in 1934 in Los Angeles and was thought to be an outbreak of atypical polio. After the outbreak in Akureyri, Iceland in 1946, the disease came to be called 'Akureyri Disease' or Icelandic disease through much of the 1940s and 1950s. It was named ME after London's Royal Free Hospital outbreak in 1955. Other names included benign myalgic encephalomyelitis and epidemic neuromyasthenia.

After the Incline Village outbreak in Nevada in 1984, the disease came to be called and redefined as chronic fatigue syndrome (CFS). The most recent putative outbreak was in Arizona in 1996. 

Disease name[עריכה | עריכת קוד מקור]

דף תוכן : Names of myalgic encephalomyelitis and chronic fatigue syndrome

The name myalgic encephalomyelitis was first used in 1956 in an article in the Lancet medical journal to describ findings from the 1955 Royal Free Hospital outbreak in London, UK.[19][18][20] The term myalgic encephalomyelitis is a portmanteau of several of the key signs and symptoms of the disease: myalgic (muscle pain), encephalo (brain), myel (spinal cord), itis (inflammation).[18][21] The central nervous system (brain and spinal cord) are inflamed.

Benign myalgic encephalomyelitis[עריכה | עריכת קוד מקור]

Benign myalgic encephalomyelitis was the term used by the World Health Organization from 1969,[4] with the prefix "benign" used to denote that M.E. was not fatal, the prefix benign was later dropped since M.E. can cause death, for example the deaths of Merryn Crofts and Sophia Mirza.[18][22][23] Merryn Crofts had very severe ME, was bedbound and unable to eat. She weighed six stone (84 lbs) at her death; her autopsy revealed inflammation of the dorsal root ganglia.[citation needed] Merryn's death certificate was the second in the UK to attribute a death to ME.[22]

Disease of a thousand names[עריכה | עריכת קוד מקור]

Myalgic Encephalomyelitis has been referred to as the "disease of a thousand names".[24] Other names used or proposed in the history of the myalgic encephalomyelitis include atypical polio, Icelandic disease, benign ME, epidemic neuromyasthenia, chronic fatigue syndrome, Chronic Fatigue Immune Dysfunction Syndrome (CFIDS), and systemic exertion intolerance disease (SEID).[24][16] This has lead to much confusion as a variety of names have been used at different times to describe discrete outbreaks as well as a larger and potentially more heterogenous population of sporadic cases, defined by a wide variety of diagnostic criteria. Some names have emphasized particular symptoms or pathology, including chronic fatigue syndrome and myalgic encephalomyelitis.[18]

A survey by The MEAction Network in 2016 found that the majority of patients prefer the name ME to other names including chronic fatigue syndrome.[25]

Myalgic encephalomyelitis (ME) was the original name for chronic fatigue syndrome (CFS); the names are used interchangeably or with the acronym ME/CFS.[21]

Onset[עריכה | עריכת קוד מקור]

דף תוכן : Onset of ME/CFS

According to Dr Byron Hyde, after an incubation period of 4 to 7 days, the prodromal phase generally involve a flu-like illness with low-grade fever.[26] In the majority but not all cases, an infection or infectious process is evident.[26] Two to seven days later, a chronic phase commences, characterized by a measurable diffuse change in the function of the CNS. It is this second phase, persistent phase that most characterizes ME.[27][2][26]

Signs and symptoms[עריכה | עריכת קוד מקור]

Myalgic encephalomyelitis is a neurological disease that affects multiple bodily systems, causing a widespread combination of symptoms.[28] Symptoms can range from mild to very severe and can include:

Myalgic encephalomyelitis is an acquired neurological disease with complex global dysfunctions. Pathological dysregulation of the nervous, immune and endocrine systems, with impaired cellular energy metabolism and ion transport are prominent features. - International Consensus Criteria

Symptom presentation and severity can vary considerably day to day and even hour to hour.[2] Overexertion can exacerbate all symptoms, and post-exertional malaise often delayed by 24 hours or more.[29][2] The US National Institutes of Health (NIH) notes that sensitivity to noise, light and chemicals may force patients to withdraw from society.[30]

Post-exertional malaise[עריכה | עריכת קוד מקור]

דף תוכן : Post-exertional malaise

A core symptom, post-exertional malaise (PEM), is intolerance to previously trivial mental or physical effort such as attending a child's school event, running an errand or grocery shopping, taking a shower or brushing teeth; this causes a worsening of symptoms, and deterioration of health from persistent or repeated exertion.[5][31][8]

Jennifer Brea is an American who was studying at Harvard; while on a trip to Kenya she became very ill with what would eventually be diagnosed as ME/CFS. Brea began experiencing neurological problems. Her neurologist diagnosed her with "conversion disorder" (hysteria). When walking home from his office, she collapsed. Jen then needed to use a wheelchair to keep her legs up due to POTS as her blood pools into her legs. View her TED Talk What happens when you have a disease doctors can't diagnose

The severity of a patient's symptoms often depends on the time period since the disease was contacted and rate of progression of each patient. The rate of progression can be accelerated by physical or cognitive activity beyond a patient's limits over long periods, which typically entails anaerobic activity.[citation needed]

דף תוכן : Definitions of myalgic encephalomyelitis and chronic fatigue syndrome

There are several proposed criteria for diagnosing ME including the International Consensus Criteria (ICC) and the Canadian Consensus Criteria (CCC). The original criteria developed by Melvin Ramsay, the Ramsay definition, is not used for diagnosing ME today.

Generally accepted criteria for diagnosing ME/CFS and ME[עריכה | עריכת קוד מקור]

ME/CFS (SEID) is accurately diagnosed when the core symptoms are met. The Institute of Medicine report is a whole is a comprehensive review of the medical literature available at time of publication (2015). Adults can be diagnosed at 6 months while pediatric cases are diagnosed at three months.

Other diagnostic criteria[עריכה | עריכת קוד מקור]

Several, overly broad criteria have been proposed and are in use. These criteria likely capture some patients with the disease characterized in the medical literature on epidemic ME, exclude others, and also include patients with a wide range of other undiagnosed conditions including cancer, depression, and a range of autoimmune diseases. The United Kingdom's Oxford criteria for chronic fatigue syndrome is the broadest and likely least discerning definition. (The US Institute of Medicine report called for its complete retirement.)[43] The US Centers for Disease Control's (CDC) Fukuda criteria, in use since 1994, is also overly broad. The Institute of Medicine report developed the criteria of Systemic Exertion Intolerance Disease (SEID) and although it can diagnose ME patients with the minimum core symptoms,[44][45] it does not describe the array of symptoms those suffering with ME experience. Symptoms such as neurological, immune/gastrointestinal/genitourinary impairment, and energy metabolism/ion transport impairment; these symptoms are necessary for a diagnosis under the ICC.[28] The CCC requires neurological, autonomic, neuroendocrine, immune system, and myalgia symptoms to meet its ME/CFS diagnostic criteria.[6]

Differential diagnosis[עריכה | עריכת קוד מקור]

The signs and symptoms of ME can be similar to other medical problems, "such as cancer, multiple sclerosis, lupus, brucellosis, or another condition."[2][6] Additional testing may be needed to help distinguish ME from these other problems.[45]

A Norwegian CFS/ME study shows that the disease affects all ages, with two peak ages of 10-19 years and 30-39 years; it is more common in women than in men.[46] Research by the Open Medicine Foundation cited in its paper, Metabolic features of chronic fatigue syndrome which studied severe CFS, found that the disease is different in men and women but this is not related to testosterone or estrogen. Michael VanElzakker notes there are male and female differences in neuropathic pain. A study of UK and Dutch cohorts found "younger children had a more equal gender balance compared to adolescents and adults."[47]

Potential causes[עריכה | עריכת קוד מקור]

Although risk factors for myalgic encephalomyelitis have been identified, no single definitive virus has been found in all cases, which has led to the claim that ME is a common end path of a variety of infectious insults.[49][50][51] It is still possible ME involves some combination of both environmental and genetic factors. Various theories try to combine the known data into plausible explanations.[52][53] Several theories suggest that ME is an inappropriate immune response to an infection, a theory bolstered by the observation that there is sometimes a family history of autoimmune disease.[54] There is also a shift from the Th1 type of helper T cells, which fight infection, to the Th2 type, which are more active in allergy and more likely to attack the body.[55][56]

Naomi Whittingham lives in the UK with a severe case of ME. Naomi became ill at age 12 with a routine virus and never recovered. She advocates for ME by doing interviews, writing the blog A Life Hidden, and supporting her brother Tom Whittingham's marathon fund raising for ME Research UK

Viruses[עריכה | עריכת קוד מקור]

דף תוכן : Virus

Other theories describe ME as an immune response to a chronic infection. The association between ME and the Coxsackie B, Human herpesvirus 6, and HHV-7 viruses[57][58][59] suggests a potential viral contribution in at least some individuals. Evidence from epidemic myalgic encephalomyelitis strongly point to an enterovirus, however, in most outbreaks, no virus was successfully isolated.

Bacteria[עריכה | עריכת קוד מקור]

דף תוכן : Bacteria

Others believe ME may sometimes result from a chronic infection with spirochetal bacteria, such as lyme disease. Another bacterium that has been implicated in ME is chlamydia pneumoniae.[60][61] Protein findings relating to several infections have seen found in the oligoclonal bands ME of patients.[62]

The vagus nerve infection hypothesis (VNIH) accounts for why so many different infectious onsets could be responsible. The vagus nerve runs from the brain stem and throughout the body and has an impact on many body systems.

Given the uncertainty regarding the cause, ME and CFS patients are barred from donating blood or organs in the United Kingdom, United States and New Zealand while symptoms persist.[63][64][65]

דף תוכן : Treatments

There is no cure for ME and no country has approved any pharmacological treatment for the disease except, Argentina which has approved Ampligen for the treatment of severe ME/CFS.[14] However the effectiveness of Ampligen is under dispute.[66] Other medications have been used off-label for ME with varying effectiveness in some patients.[6][28]

Treatments for sleep problems, headaches, pain or other symptoms are utilized by some doctors for some patients although these are treating symptoms and not ME itself.[28]

Success of treating symptoms of ME is not well researched or documented.

An immune system modulator drug called Rituximab has failed in a phase III clinical trial.[67] The antiviral Valganciclovir failed in a controlled nine month study against ME patients positive for Herpes Simplex 6 and Epstein Barr viral infections.[68]

Epidemiology[עריכה | עריכת קוד מקור]

דף תוכן : Epidemiology of Myalgic Encephalomyelitis and Chronic Fatigue Syndrome

ME has been found world-wide, in at least 75 epidemics documented in published papers from the 1930s to the 1980s.[69] Epidemics often occur in enclosed communities such as schools and hospitals.

As observed in many autoimmune disorders, ME is more common in females than males; the mean sex ratio is approximately 2-3 females for every male.[70] In children the sex ratio is approximately equal.[71]

Co-morbidities[עריכה | עריכת קוד מקור]

דף תוכן : Comorbidities of Myalgic Encephalomyelitis

Clinicians have observed several predisposing conditions, co-morbidities, overlapping conditions, and increased risks for secondary diseases in patients with ME.[6][8] However, as no large-scale epidemiological studies, genetic studies, or family studies have been done, there is little that can be said definitively about the rate or underlying biological reasons for these potentially related conditions. Overlapping diagnostic criteria and the lack of a biomarker in many of these conditions add to the confusion and diagnostic uncertainty. Moreover, certain conditions such as postural orthostatic tachycardia syndrome (POTS) and neurally mediated hypotension (NMH) and idiopathic intracranial hypertension (IIH/IH) and fibromyalgia (FM/FMS) can occur in or be co-morbid with numerous conditions, including ME.[72][73]

The following are some syndromes and diseases that have been associated with or misdiagnosed as ME:

A Swedish study of 234 ME/CFS patients meeting the Canadian Consensus Criteria found that 13.2% had tonsillar herniations severe enough to be considered a Chiari Malformation. 49% had hypermobility and 20% met criteria for hEDS (Ehlers-Danlos syndrome with hypermobility), while 96% had fibromyalgia trigger point pain, with 67% meeting the diagnostic criteria for fibromyalgia.[77]

Notable studies[עריכה | עריכת קוד מקור]

דף תוכן : Notable studies

Due to lack of funding by governments around the world there has been little biological research into ME/CFS. There are studies which do reveal neurological involvement, metabolic features, and other abnormalities.
