Jackie: __________________________________________"...it became clear to me that LEAP helps people with D. I must say, I would have had much more respect for the LEAP program had I been told clearly that they probably COULDN'T help." ___________________________________________You raise several key points with your post that can help people better understand not only how their symptoms are assessed for probable cause, but what the LEAP protocols are and are not.LEAP is what is called a "Disease Managment" or "Symptom Reduction" Program...depends which term a particualr doctor prefers. It was developed by doctors and dieticians on live IBS patients (and patients with other symptoms as well) over a 3 year period nearly 2,000 were involved in working out the system, each element). It is based in part on the use of a tool of a patented, proprietary testing method (developed by immunologists) which allows the assay of a wide array of foods and chemicals, instead of trying to pick through by serial oral challenges, to which the immunocytes (beginning in the smll intestine and then in the blood stream when food components are absorbed) can react inappropriately. It has been discovered by using direct-jejunal isolation studies (and other indeirect methods) that a population of patients who are diagnosed as having IBS (usually the d-predominant or cyclic type so the population is quite large) suffer from this hypersensitivity. The chemicals released "at the wrong time" by immunocytes provoke pain, spasm, sensitivity to pressure within the lumen, disruption of normal digeation, increased mucous production, and even evacuatory episodes.When you develop a Disease Managment program you must develop methods of attempting to separate the populations of people who have higher probability of being helped from those with the lower probability of being helped by the methods used in that DM program.Then you must have protocols which produce positive outcomes...as measured by whatever indicates improvement in the disease being managed. In this case...symptom reduction is the goal up to and including remission.There are also elements where you have to have tools for assessing compliance, and tools for tracking progress, and procedures for the implementing doctor or therapist to follow to ensure standardization, and patient specific therapies.This is what differentiates "Disease Managment Programs" from "treatments". Programs are coordinated and multi-modality regimens for a selected population with a targeted probability of success and whose outcomes can be monitored.The Symptoms Surveys used, as you can see when you look at it, are designed to survey more than just GI symptoms. Why? Because if your GI symptoms are precipitated by immunocyte hypersensitivity of any kind to a food or a chemical in foods (non-allergic...non IgE...standard allergy tests are for that..and cannot detect these reactions this testing does and vice versa...they are complementary like doing a blood count and a urinalysis; true food alergy is much less frequent than non-allergic hypersensitivity and much harder to accuratley assess)..anyway if this is occurring it is well known that the patient also suffers some degree of SYSTEMIC symptomology as well. This is because there are as many as (8) different possible mechanisms of hypsersensitivity response which may occur, and result in Any Combination of up to 100 different mediators being released not only into the lumen and wall of the small intestine (it starts where digestion is taking place).For example when certain lymphocytes are involved (they circulate in and out of the bloodstram and lymphatics and through the bowel wall) of course if they react they reenter the blood stream and dump chemicals there too. Or if there is a problem with other intra-vascular reactions in response to what gets through the bowel wall when the permeability is altered by what happens IN the bowel wall, mediators released in the blood stream travel everywhere and can effect many diferent organ systems inlcuding the CNS.So the fisrt part, the very first part, of assessing the probability that food or chemical hypersentivity is a possible culprit is to assay the known symptomologies in total. The higher the severity and/or frequency of sysmptoms and the wider the array, the higher the probabilities that this is part of or even all of the problem with the patients symptoms.One also has to ask a few questions about history and medications as well, as these will ahve bearing on the symptoms as well....what may appear to gbe diet related could, for example be thyroid related. or the patient could have an actual true IgE allergy which can often be assessed by a series of simple questions as to probability.So when you get a person with an assigned diagnosi, like your son, of IBS BUT the only symptoms are 'Gas and Pain'...this rasies questions as to the veracity of either the reported symptoms or the diagnosis since no change in bowel habits was reported and this is, according to the ubiquitous ROME II CRITERIA part and parcel to an IBS diagnosis. So this will make any LEAP dietician or the Patient Care Cordinator (who has worked with the immunologists and allergists for years and teaches the subject to doctors) more likely to be "ambivalent" in their assessment of probabilities.I the case of CRISTINA the ONLY SYMPTOM she reported was gas. This redcues the probability of some form of food or chemical hypersensitivity to a ver low level. There are other mechncisms much mroe LIKELY. You CANNOT RULE OUT the cindition with a symptom survey...you are trying to do exactly what you suggest we are NOT doing: maintaining credibility. Unlike some LABS who "sell testing", we do not "sell testing", that is...."take this test to rule out [ insert condition tested for]...so that they are testing people who probably do NOT have the condition which they could tell if they used s creening system. We do not sell tests, we either (in Homecare) advise the person (based on the symptom survey AND however much of the history the person volunteers) of the probablities...of the probbailitieis of whether this will help in the end (the Program) if the person enters it..either in Homecare or under the care of a LEAP doctor provider.So the wider the symptom range the higher the probability and vice versa.So it is not that LEAP is only for patients with "D" or cyclic IBS...it happens that this is the [primary smoking gun], one of the most obviosu signs of immunocyte activation absent detetcted organic disease like infection or IBD.And the opposite end of the specturm is ONE SYMTOM and NO history...like "gas". There it is much more likely the person should seek help elsewhere than invest in this program. We could very well be within righta, legality and usual and customary procedure to let the person just be tested as s screen to rule-out hypersensitivity. I would get a lot more testing done. But that is not what we are about.So, I was not present when you discussed your son, so I do not have the benefit of ading the HISTORY (whatver was reported) in the context of "GAS AND PAIN AND AN IBS DIAGNOSIS" to the probability assessment either the RD of the Patient Coordinator tried to advise you of.But they did give you a fair assessment that from what you reported they cannot "rule out" that your son does not have any hypersensitivity as the PAIN 9depending upon nature, duration, frequency, context of mediaaton and diet) is another "red flag". The pain sensitivity is heightened in some patiets with gut sloaclized reactions of w lower order, without evacuation following.the classic case of this is the c-predominant ISB victim with a cormorbid food or chemical sensiitivity. The fact they do NOT suffer evacuatory episodes reduces the PROBABILITY that this mechanism is contributing much to their symptoms, so the degree of symptom eduction seen in c-types is less than in d-types...BUT if the patients is "immotile" an has a lot of pain and gas as well, the probahiltiies just increasd. So this particular case would be MORE likely than another without the pain and gas reported as frequently or severely to experience some benefit...and that would be (if test positive) pain reduction (meditors released in the gut wall do many different things and which symptoms you get depends which type of cells and thus mediator array are involved...platelets for example are loaded with 5HT...mast cells are loaded with histamine...they both have other chemicals but each has s different predominance thus a different predominant set of side effects).So, in the view of the person seeing an IBS diagnosis guiven by a doc,, gas, and a report of pain, the degree and frequency were sufficient to subjectivley suggest that the probability of this being a componene tof the probelm is increased.But I do not hink anybody tried to slam-dunk you into putting your son into the program. They did their job as the doctors trained them to....assess probabilities from the sysmptoms and history given, and advise of them so the person can make an informed decision.IF Cristina, for example, had told me that she also sufferd spisodes of pain which were frequent and moderate to frequent and severe, my answer would have been more detailed and I would have asked more questions to ascertain whether she could be heped or not, and what the relative probabilities are.So in general it is indeed accuarte to say, as we always do, that the patient with a diarheic componenent is more liekly to benefit, and to experience greater benefit, is in accordance with following the rules by which one adminsters DM or SR "Programs", so the person can think, evaluate, and make an informed decision.If you had reported exactly what Cristina reported, you would not have been given the best guess that it is "50-50" with that symptom. It is not enough to rule IN or OUT. So you have to say that. One person might say it one way, another might say it another, but if our people did not push you to put your son in the program based on hthe info given, then they did their jobs correctly. I will guaranee you you will not alwys have that degree of objectivity with all other organizations or people who have a single modality to offer...somehow their product or service semms often to me morphable into a "one size fits all". This is merely the old rule "When your only tool is a hammer everthing is a nail".I wish there were a more black-or white way of ruling in or ruliong out by self-reported symptoms...then we could just skip any testing and get right down to the dietary therapy specific to the patients. But we cannot so we have to do that "patient selection" exercise.The Disease management Association of America guidleines for constructing DM Programs are among the guidlines the LEAP doctors and dieticians try very hard to abide by, with a "Syndrome" which does not follow a fixed set of rules, as you can see. It's easier with diabetes or wound care and the like DM prograsm as at least those pathologies are more predictable than IBS.If you have any more questions I will be glad to answer them, here or privately by email. Just bear with me as I only have now maybe one hour a day each morning to come and visit so it may take a day or two to get the reply time in...and I am a poor editor of typos...time time time is so short.Eat well. Think well. be well.MNL
