Why did the 1988 CDC definition damage our knowledge and understanding of this epidemic and endemic disease? Remember in describing the Lake Tahoe epidemic this committee were describing a typical Myalgic Encephalomyelitis (ME) Epidemic. Major Problems of the 1988 CDC definition It is my opinion that the CDC 1988 definition of CFS describes a non-existing chimera based upon inexperienced individuals who lack any historical knowledge of this disease process. The CDC definition is not a disease process. It is (a) a partial mix of infectious mononucleosis /glandular fever, (b) a mix of some of the least important aspects of M.E. and © what amounts to a possibly unintended psychiatric slant to an epidemic and endemic disease process of major importance. Let us try to decipher this definition. 1. The principal author: Dr Gary Holmes is one of those men who it is difficult not to like. From my limited knowledge of Dr Holmes it is my opinion that he is well organized, brilliant, a kind man and the sort of person any university would want to have on staff. To my knowledge he never continued to show any interest in this disease process and Pub Med and Google searches fail to reveal any subsequent scientific papers concerning M.E. or CFS. 2. The other authors: So curious was the 1988 CDC definition that if you review the authors, you will find that the majority had never published on M.E. or CFS either before or after this definitional publication and the majority had never ever to my knowledge ever before or since examined or investigated any serious number of CFS patients. In fact, I would estimate that the majority had never actually examined and investigated as single M.E. patient. 3. The curious name: The authors named the disease Chronic Fatigue Syndrome: Fatigue is a totally undefinable concept. Fatigue is impossible to measure or quantify. Fatigue is so non-specific that it can be a common element in any acute or chronic disease and many psychiatric diseases. Worse, it redirects the medical and public attention to the totally undefinable fatigue and away from the obvious Central Nervous System changes in these patients. Much worse, it makes fun of a serious illness since most people and most physicians tend to equate fatigue with laziness, work avoidance, something that a bit of effort will chase away. It has turned out to be a damning indictment to all M.E. patients. 4. The first Major Criteria: This 1988 CDC definition contains (a) two major criteria, (b) 11 Minor Criteria, © three physical criteria. Let us start with the first major criteria: " A new onset of persistent or relapsing, debilitating fatigue or easy fatigability in a person who has no previous history of similar symptoms, that does not resolve with bed rest, and is severe enough to reduce or impair average daily activity below 50% of the patients premorbid activity level for a period of at least 6 months. " This major criterion does not clearly distinguish between acute or gradual onset diseases. In all M.E. epidemic or endemic patients the patients represent acute onset illnesses. The fatigue criteria listed here can be found in hundreds of chronic illnesses and clearly defines nothing. 5. The second Major Criteria: This makes the illness CFS a disease of exclusion. The definitional statement is: " Exclude all other disease processes. " Any disease process that has major criteria, of excluding all other disease processes, is simply not a disease at all; it doesn't exist. In effect, by either the first or second major criteria this is nor a measurable illness and a disease that is not measurable or testable simply does not exist. What did Dr Holmes and his colleagues miss? They missed the fact that M.E. is (a) an acute onset illness, (b) the fact that M.E. is a measurable diffuse brain injury, © in a complete form, M.E. has a dual inception, an infectious illness followed by the diffuse neurological aspects of this disease. 6. The Minor Criteria are consistent with M.E. but unfortunately for the greater part, are also consistent with Infectious Mononucleosis that I believe the authors of these diagnostic criteria thought they were describing. 7. The Three Physical Criteria of the CDC 1988 Definition: These findings are totally related to infectious mononucleosis and not to the normal or average Myalgic Encephalomyelitis. The criteria fail to distinguish the biphasic nature of M.E. as mentioned before, the initial infectious illness that often resembles the minor infection that heralds another biphasic disease, paralytical poliomyelitis. The infectious disease process varies but is usually minor and after three or four days is usually unverifiable so that any researcher who quotes the patient as having the three physical criteria when he or she examines the patient probably at the very least can be accused of being very imaginative. First it is not possible to examine any patient in the first days of illness unless it is an epidemic situation. In several chronic thousand patients I have examined the three physical criteria simply do not exist in more than 1% of the patients examined. What are the CDC Physical Criteria? a. Low-grade fever with an oral temperature between 37.6 and 38.6 centigrade, b. Non-exudative pharyngitis (without any pus or discharge), c. Palpable or tender anterior or posterior cervical or axillary lymph nodes less than 2 cm in diameter. In the chronic patients the temperature tends to be normal or subnormal. Most chronic patients have no pharyngitis, they may have a dry pharynx, they may have an injected pharyngeal area around the tonsilar pillars, (Anne Mildon effect) but generally they don't have a classical pharyngitis as seen in any acute infectious disease. As to the palpable lymph nodes, all healthy patients well or otherwise unless they are severely obese have palpable lymph nodes. Since many M.E. patients have hypersensitive skin or fibromyalgia-like pains of course they have tenderness. But painful lymph nodes scarcely are different from what is found in any acute upper respiratory tract infection. If you are going to list physical findings then you have to first specify whether this is in the first few days of the illness or in the chronic phase and as mentioned almost no physician will ever see acute onset illness unless in an epidemic. In other words these physical criteria are at best of no diagnostic importance and in general, useless. 8. The Insurance Company - psychological bias: the direction given in the name Chronic Fatigue Syndrome has opened the door for insurance companies to invent and support a pseudo-psychological treatment of physical and cognitive therapy that in my view has been used to push the patients so far that they then quit the program and this allows the insurance company to define the disabled patient as non-compliant and allows the insurance company to stop insurance payments. Since many if not most insurance policies also cut the patient off after two years of disability, this psychological interpretation has been destructive to the many patients disabled by M.E. 9. The pharmaceutical companies bias: These companies have also jumped into the door opened by this name of chronic fatigue - depression association in recommending a non stop series of " new and better " antidepressive medications that not only have added little if anything to the patients recovery but in many cases have caused suicides and even greater fatigue. Since many of these medications have a side effect of causing obesity, the patient's self worth is often further deteriorated. _http://www.imet.ie/imet_documents/BYRON_HYDE_little_red_book.pdf_ (http://www.imet.ie/imet_documents/BYRON_HYDE_little_red_book.pdf) This email was cleaned by emailStripper, available for free from _http://www.papercut.biz/emailStripper.htm_ (http://www.papercut.biz/emailStripper.htm) Quote Link to comment Share on other sites More sharing options...
