Systemic Exertion Intolerance Disease

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

The diagnostic criteria currently recommended by the Centers for Disease Control is the Institute of Medicine criteria (2015)[1] or sometimes the National Academy of Medicine criteria, as the IOM is now called the NAM. Systemic Exertion Intolerance Disease, or SEID, was the name initially proposed by the committee; however it has not been adopted as a new name for ME/CFS by US organizations; CDC and NIH both refer to the disease as ME/CFS when referring to the IOM critera.[1][2]

The IOM criteria was first proposed and published by an Institute of Medicine committee on Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) in 2015, at the request of the CDC.[3]

Other Common Symptoms[edit | edit source]

Many people with ME/CFS also have other symptoms, such as:

Some people with ME/CFS may also have:

Notes[edit | edit source]

Orthostatic intolerance is also useful for a more severe presentation of the disease; symptom severity and other symptoms are outlined in the Institute of Medicine report.[8]

Adults can be diagnosed at six months of illness and pediatric cases are diagnosed at three months.

Diagnostic criteria for clinicians[edit | edit source]

Diagnostic Algorithm[7]

Diagnosis requires that the patient have the following three symptoms:

1. A substantial reduction or impairment in the ability to engage in pre-illness levels of occupational, educational, social, or personal activities, that persists for more than 6 months and is accompanied by fatigue, which is often profound, is of new or definite onset (not lifelong), is not the result of ongoing excessive exertion, and is not substantially alleviated by rest, and

2. Post-exertional malaise,* and

3. Unrefreshing sleep*

At least one of the two following manifestations is also required:

1. Cognitive impairment* or

2. Orthostatic intolerance

* Frequency and severity of symptoms should be assessed. The diagnosis of ME/CFS (SEID) should be questioned if patients do not have these symptoms at least half of the time with moderate, substantial, or severe intensity.[9][10]

Development[edit | edit source]

In 2014, the U.S. Department of Health and Human Services (HHS), the National Institutes of Health (NIH), the Agency for Healthcare Research and Quality (AHRQ), the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), and the Social Security Administration (SSA) asked the Institute of Medicine (IOM) to convene an expert committee to examine the evidence base for ME/CFS. In Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness, the committee proposes new diagnostic criteria that will facilitate timely diagnosis and care and enhance understanding among health care providers and the public. These criteria, based on expert analysis and the most up-to-date scientific literature, are streamlined for practical use in the clinical setting. The IOM committee also recommended that the name of the disease be changed—from ME/CFS to systemic exertion intolerance disease (SEID)—to more accurately capture the central characteristics of the illness.[3] However, this name was not adopted by government organizations and not embraced by advocacy organizations.[1][2]

Authors[edit | edit source]

The committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) consisted of Ellen Wright Clayton, Margarita Alegría, Lucinda Bateman, Lily Chu, Charles Cleeland, Ronald Davis, Betty Diamond, Theodore Ganiats, Betsy Keller, Nancy Klimas, A Martin Lerner, Cynthia Mulrow, Benjamin Natelson, Peter Rowe, and Michael Shelanski.

Criticism[edit | edit source]

The Institute of Medicine criteria was met with community criticisms, including the following:

  • too few symptoms were required; in particular, nervous and immune system symptoms present for CCC and ICC criteria were absent
  • unclear descriptions of post-exertional malaise
  • absence of pain, which is listed as a "common symptom" but not part of the diagnostic criteria

Twisk (2017) stated that ME and CFS are different illnesses, with ME being a neuromuscular disease and CFS being a partially overlapping fatigue-based illness, and that it was not possible to replace both ME and CFS with a single diagnostic entity. Twisk also stated that SEID included some patients that did not meet either ME or CFS diagnostic criteria.[11]

IOM criteria information has been incorporated into the CDC's ME/CFS website under the tab Information for Healthcare Providers under the "Resources" heading.[12]

In popular culture[edit | edit source]

A February 2016 comic strip referred to SEID and implied it is simply tiredness. See: Blondie comic
