Low dose immunotherapy (LDI) is a treatment for “turning off” an overactive immune system. This applies to allergies, autoimmune diseases or any process in which the immune system is activated.
Traditional “immunotherapy” involves administering a dilute solution of the allergen by injection, under the tongue drops or topical cream. The concentration of allergen is relatively high and stimulates the body to make “blocking antibodies” which block the portion of the immune system that is overactive. The injections take years to work and are dangerous due to the high concentration of allergen. Under the tongue allergy drops are much quicker and safer, yet both injections and drops are limited for use only with inhalants such as to pollens or animal dander.
LDI is different because is uses much lower concentrations of allergens and may be used to treat not only inhalant allergies, but also allergies to foods, chemicals and certain autoimmune or overactive immune conditions. LDI is given as sublingual as an under the tongue drop since it gains access to the immune system quite well in this manner.
LDI for Allergies
With LDI we have about 90% success eliminating typical allergies such as hayfever. Our environmental mix contains hundreds of antigens to all sort of plants and animals. We can also desensitize to foods, chemicals or molds.
Note that traditional allergy shots are “single antigen” meaning the mix only contains substances tested positive with by skin testing and they are only about 50% effective.
LDI for Autoimmune Disease
Using LDI for autoimmune diseases and conditions that involve an overactive immune system is a truly unique therapy. It is well established that certain autoimmune diseases, and perhaps most of them, are “triggered” by an initial infection. As the immune system recognizes the infection and mounts an attack there is a cross reactivity with their own tissue. This process is called “mimicry”.
Sometimes this happens only in people with specific genetic mutations in their self-recognition genes called human leukocytic antigens (HLA), which are part of the major histocompatibility complex markers. The HLA gene family provides instructions for making a group of related proteins known as the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body’s own proteins from proteins made by foreign invaders such as viruses and bacteria.
Even after the bacteria are eliminated the immune system remains activated and the autoimmune process continues. Since the immune response is coded to recognize the original bacterial trigger, including the specific bacteria in the LDI will lead to a desensitization of the immune system, calling off the attack on both the bacteria and the body tissue.
Two examples of mimicry can elucidate this process better, and also point out why treating an acute infection may resolve a symptom, yet treating a chronic infection may be fruitless as the immune response is actually causing the symptoms.
First, consider acute strep throat, in which antibiotics kill the bacteria quickly before the immune system gets very upset. If strep goes untreated however, about 1 in 1-3000 people will get rheumatic fever which is an autoimmune type reaction that requires anti-inflammatories to treat, not just antibiotics. The autoimmune reaction was triggered by strep.
Second, consider Lyme’s disease, in which once again early antibiotic therapy will usually kill the bacteria before the immune system really gets involved. But, with chronic Lyme’s, the immune system activation is what causes the symptoms. Not only do the bacteria mutate and hide via different intracellular and cystic forms making eradication increasingly impossible, eradication still does not necessarily turn off the immune response that is causing most of the symptoms. Chronic Lyme should be thought of as an autoimmune disease…
The LDI solutions come in different concentrations. A 100-fold dilution is referred to as 1C. Each “C” represents another 100-fold dilution, such as a 2C dilution would be a 10,000-fold dilution, a 3C is 1,000,000, and so on. Most LDI dilutions are in the 6-8C range, making them 1,000,000,000,000 to 10,000,000,000,000,000-fold dilutions.
For comparison, homeopathic dilutions start at 12C, which is maximum dilution from which one molecule of the original substance potentially still exists. Homeopathic preparations are usually in the 30-200C dilutions. As another comparison, traditional immunotherapy typically uses 1-2C dilutions.
Some LDI therapies are such that one dilution seems to work well for all patients, while others have a wide range of dilutions. If the dilution is too strong, the patient will have a flare of their symptoms. If the dilution is too weak, the patient will not improve. Since most patients respond by the 2nd or 3rd dose, if there is no improvement by then, a stronger dilution should be considered. Or, consider that symptoms are related to a different antigen, or that the LDI is not the correct therapy in general.
If you have a delicate, fragile, or worried patient, consider using a weaker dilution. If you have a patient that is anxious to see results and fairly stout of constitution, use a stronger dilution. If a patient has a flare of symptoms from the LDI, a standard short burst of steroid is usually sufficient to regain control of symptoms. The next dose should be more dilute.
Choose which antigen or antigens are used depending upon the patient’s condition and/or symptoms. A thorough symptom review aimed at determining triggers is important. If a patient clearly has hayfever symptoms when exposed to grass, or animal dander, then one would use the IC mix. If perfumes or chemical smells trigger symptoms, then one would use the CF mix. As many conditions are related to food allergies the LX/MX mixes are often used for conditions beyond simple food allergies, usually in combination with other antigens.
LDI doses are given at 7-week intervals – no sooner. The immune system has a memory and does not like to be told twice to do something. Repeating the same LDI dose sooner than 7 weeks will cause a flare of the patient’s symptoms.
However, you may administer different antigen mixes at any time in relation to one another. For example, one might start the Lyme mix, wait to see how the patient responds, then a week later give another antigen mix, such as p/k for rheumatoid arthritis. In this manner one can determine which mix produced a flare in symptoms. Once the doses are determined one can then schedule all the doses on the same day for convenience. Also, if an antigen mix is too weak, then the next stronger mix may be given in a week.
For complicated or fragile patients, or when using antigen mixes more prone to need variations in dosing (e.g. Lyme, Yeast), it is simplest to start only one antigen at a time in order to know how to adjust in case of symptom flares or non-response.
Combinations can be started together for some conditions, such as Crohns, and are notated by the “and” notation, e.g. LX/MX “&” Crohns/IBD means both antigen mixes are usually started together.
For some conditions we might start with a single antigen, and if no response is achieved after a few doses, try a different antigen. For example, with non-specific arthritis we might start with LX/MX, and if no response, try CF, and if no response try Yeast, and if no response try Strep, and so on… I call this “going fishing” for the right mix.
Finally, one may use autologous samples from the patient to be used in the mix. Stool samples represent a likely reservoir for chronic infection that may be triggering an immune response, so this is a logical antigen. Sinus washing are often helpful in cases of chronic congestion.
Initially most patients will get some relief of their symptoms for a few days to weeks. They may call and beg to get another dose prior to the 7-week interval – don’t do it. Eventually, by the 4th to 5th dose, they will start getting symptom relief all the way through the 7 weeks until the next dose. At this point one can stretching out the dosage interval, basically until symptoms start returning. Typically, after a few years, patients only need the dose once or twice per year to maintain remission.
We only charge for the administration of the LDI. The actual antigens are no charge. We charge $25 to start, until we know the LDI is going to work. Once we have found a winner then we charge $100 for what we refer to as the “core” dose. One great thing with LDI is that it’s super safe, inexpensive and easy to try.
