Immune response symptoms and conditions

Why does Singulair cause these symptoms? I am going to give my explanation which is only a HYPOTHESIS. This should not be categorized as any thing but an educated guess. This is not backed by scientific research because nobody will do any research that would appear to anger
Merck even if people are suffering in the thousands.

1. The original research that preceded the development of Singulair (montelukast) seemed to focus on the theory that asthma was caused by an unusual immune response to certain pathological stimulus. There are many references to the observation that a high percentage of asthma sufferers are people whose asthma is caused by fungus. Many people suffer from asthma and are told that they are allergic to dust mites. Dust mites can live only because the fungus aspergillus pre-digests the
food source that dust mites can then absorb. Other sources of fungus occur in the home due to dampness or problems with wood rot.

2. The body's immune system fights certain categories of pathogens such as bacteria and fungus by creating nitric oxide which kills them at the site where they try to enter the body. The mast cell is the immune cell that is responsible for the production of nitric oxide. Mast cells are found in the skin, airways, intestines etc. The mast cell is capable of many different types of biochemical functions that are designed to signal other cells or other chemical responses. When the mast cell knows that pathogens
are present and nitric oxide is NOT produced, then it signals other immune cells to be sent to the site of the infection. Thus in the case of asthma, it is known that excessive numbers of eosinophils appear in the airways and these cells create inflammation.

3. Singulair was developed for asthma and later allowed to be prescribed for other reasons. I believe that montelukast probably creates a source of nitric oxide that prevents the mast cell from signalling for other immune cells to arrive at the source of infection. I arrived at that conclusion from studying the chemical structure of montelukast, the chemical structure of the gene cysLT1 receptor, and the chemical structure of the cell wall of fungus which would be what the mast cell uses to determine "what to do in order to kill the fungus."

The researchers who invented montelukast first had to clone the gene-cysLT1 receptor meaning that they had to be able to identify the gene and replicate it. Then by trial and error they had a find a "chemical"
that would bind (connect chemically) to the cysLT1 receptor. The theory would be that montelukast would take the place of the fungus or other pathogen and thus prevent the gene from reacting to produce the
responses that the sick patient with asthma produced. Merck says in the literature that montelukast binds with the cysLT1 receptor in order to prevent the mast cell from signalling the eosinophils to arrive in excessive
numbers that cause inflammation. I believe that montelukast is also causing the production of an amount of nitric oxide that is actually killing the pathogens that are present. For one thing, I would think that it
would be dangerous to incapacitate the immune system in that way without providing a way to kill the pathogens. I don't believe that the asthma response is just allergies to something like dust. Pollen from trees and flowers is loaded with fungus spores.

4. IF, IF, IF, montelukast does actually produce nitric oxide, then it does so by binding with the gene. Any place in the body where a molecule of montelukast encounters the cysLT1 receptor (a gene) then the corresponding molecules of nitric oxide are produced before the liver enzymes break the montelukast molecules up. Nitric oxide is TOXIC and
INFLAMMATORY. So let's look at the symptoms in regard to the location of the cysLT1 receptors. The location of these symptoms would not be places in the body where the mast cells normally encounter fungus or bacteria. The cysLT1 also has other functions in that it communicates with the cysLT2 receptors. Obviously, nitric oxide
should not be produced in these locations because of the signalling effect of nitric oxide on other physiological functions.

a. intestinal pain - the cysLT1 receptors are located in the small intestines
b. leg pain actually caused by vasculitis - cysLT1 receptors are found inside blood vessels- consistent with the fact that montelukast causes
Churg-Strauss
c. some people who didn't have asthma develop asthma - the cysLT1 receptors are in the airways
d. nightmares, depression, neurological damage - when montelukast penetrates the blood brain barrier probably due to unusual conditions of blood pH or electrolyte imbalance then nitric oxide in the brain causes neuron damage and excitoxicity

5. Why do some patients not experience side effects? Probably because genetically they are completely compatible with the model that researchers created when they cloned the cysLT1 receptor gene. I didn't not find any information about whether researchers knew that there are many different variations of this gene.

6. IF, my theory is even close to being correct, then why doesn't Merck do anything about researching these side effects. Maybe because nobody in the company knows how this drug works but the researchers who created it. All of the Merck literature is very vague about any biochemical information.

Again, this is just speculation and hypothesis. I have made an attempt to put this in simplistic language and therefore sacrifice scientific accuracy. But, I think that you will get the point.

SINGULAIR IS VERY DANGEROUS TO PATIENTS WHO EXPERIENCE NEGATIVE SIDE EFFECTS. DOCTORS SHOULD JUST REALIZE THAT
THOSE PATIENTS ARE NOT COMPATIBLE WITH THE MODEL FOR THE DRUG.

I am currently 58 years old and lead a very active, healthy lifestyle. I began taking 10mg of Zocor, along with 1000mg of niacin in the summer of 2004 to reduce cholesterol (251) and triglycerides (571). The therapy dramatically improved my blood tests, however, within 6 weeks, I began to experience minor chronic skin infections, both fungal and bacterial. They were easily controlled with topical over the counter type medications, but they were annoying. At no time was this new condition linked to the statin/niacin therapy by my doctor(s). The infections became progressively worse over the next 3 years, and evolved into chronic folliculitis in my scalp, neck, and face, cystic acne, and persistent fungal infections that were becoming more difficult to control. In addition, I began to get chronic eye infections. It was as if my immune system was becoming ineffective. I stopped taking niacin in December of 2007 and the symptoms immediately lessened. I stopped taking Zocor in March of 2008 and within 2 weeks, all the skin problems and eye infections completely ended. My health was restored completely and I am glad to have put that whole mess behind me! I have been taking Omega 3 supplements to control my cholesterol and triglycerides and have had results that equaled the Zocor and Niacin therapy, with cholesterol at 160, triglycerides at 91, and a favorable HDL/LDL ratio. My physician is skeptical, but I know that my body was not functioning correctly with the statin/niacin treatment. I have found anecdotal reports from others who seem to have experienced a change in their immune system, but no mention of this as a side effect by the medical establishment.

Any one explain this....

I have posted several times. My 16 year old daughter took singulair for 4.5 years starting 11-17-03 and ending 3-28-08. She was the dancer,cheerleader who starting cutting her legs with razors and completely changed. Lost friends, depressed, withdrawn,anxiey attacks,headaches,stomach aches on and on and on..... I took her to a Psychiatrist who gave her Fluoxetine which did not help. She is doing much better now that she is off Singulair but will never be the same. She found a lump in the back of her neck and a lump in the groin area. I remember Concerned citizen mentioning Lymphoma(cancer) discovered in some of the Singulair Children because of the reduced immune system connection. I have also found some info on this on line. We are going to the Doctor Thursday and I will have tests run. Concerned citizen are you still out there? Have you found out anything else? Sue

I have used Advair for about 4 years now. My dental hygiene has always been impeccable, but recently I have had to have three root canals in a very short period of time and my dentist has gotten very concerned about how rapidly my teeth have developed so many problems. He immediately asked if I was using an asthma inhaler and I told him about Advair. He said that drugs like this cause dry mouth at night and this reduces the immune response in the salivary glands. These root canals have come at great expense and I am experiencing a lot of dental sensitivity too. The day he told me about this I threw my diskus away! I have been using some homeopathic stuff ever since and I haven't had a problem. My dentist told me to send my recent bills - some $6,000 - to my asthma doctor and ask her to pay for them!! Can't wait for that appointment. :-))

HI guys I was given pred at 60mg then over the next several weeks I tapered off. it is now about 3/4weeks since I took the last tablet. Whilst i was on them I developed quite bad hand tremors/shakes and since taper off to a low dose I have started with muscle twitches all over. Has anyone had experiences like these? And how long did they last?

Concerned citizen!!!
Just had to share the news! 3 months after stopping singulair and taking omega 3 (for last 3 months) has resulted in my 6yrs olds cholesterol going down from 236 to 202! Absolutely no diet change, in fact he has been eating worse due to throat condition/tonsils. Makes me go HMMMMM!!!

I already posted about my son's behavioral changes while on the drug from the time he was 4-7. He is now 9 years old and has been back to "normal now for 18 months. BUT- we recently had his immune system checked though a blood test and he does not have sufficient immunity for ANY viruses. My 6 year old could fight 8 out of the 14, but my son who was on Singulair for almost 4 years has a severely depleted immune system. And from what I have read, could clearly be attributed to the drug. BUYER BEWARE~!

Neurological problems and the effects of Singulair should be investigated. The Chinese researchers demonstrated that the CysLT1 receptor (singulair inhibits this receptor) does exist in the human brain. In the rat brain, they demonstrated that there is a link between this receptor and the astrocyte.

There are many researchers/doctors interested in excitotoxicity and damage to neurons.

http://www.jpands.org/vol9no2/blaylock.pdf

I would like to know how Singulair affects the astrocyte numbers and function. I would also like to know if there is a link between metabolism and the cysLT1 receptors in gastro-intestinal mucosa. Does Singulair affect the metabolic process?

So many parents are complaining of ADD/ADHD symptoms? The paper that I gave you the link correlates the immune response and excitotoxicity. That is very interesting. How many asthma and allergy patients also suffer from potential excitotoxicity? Does Singulair cause it in some patients or just make it worse in some patients? None the less--there is a possible link.

I have a question that will help me continuing looking for information. I can understand that in the case of asthma that Singulair would provide immediate relief. If it is used for seasonal allergies or other allergies without asthma, does it work right away or does it take a period of days or weeks to be effective? If it takes time, could you tell me how long it took in your situation.

Are you aware about short and long term side effects of this Devil's drug??? Of course, everybody reacts differently while take or withdraw. But there are high number of people who react terribly bad!!! Doctors do not want to recognize and discuss this. They just keep silent... Do you know exactly how Prednisone works??? Nobody knows this for sure, even doctors!!! From my personal experience, and despite gradual withdrawal, I developed extremely high blood pressure, weakness, panic attacks, depression! Practically it ruined my normal life! Doctors have no clue how to deal with its devastating side effects. Steroids are not selective. When you take a steroid, the drug infiltrates the nucleus of every single one OF YOUR CELLS AND STARTS MONKEYING AROUND WITH GENES IT FINDS THERE!!! It probably plays with hundreds of genes. And just a small number of these genes control the pain and inflammation associated with inflammatory diseases, so steroids turn many of these genes off which is good thing. However, because steroids are not selective, they also regulate the genes that control kidney, liver, BRAIN, and HEART function - which is not good thing!!! It is likely that steroid treatment plays with other genes, too, including those we do not know about a lot right now...So, Prednisone pervades the entire body, which increases the likelihood of short-term side effects and long-term DAMAGE. My advice is: THINK TWICE BEFORE TAKING PREDNISONE!!!

I was first diagnosed with hypertension in the late 80's and have been on several different medications to treat it. I think that Lisinopril is the worst that I have been on. I have extreme fatigue and severe dry and burning mouth, sore tongue and difficulty breathing and flu like symptoms. I have anxiety and PTSD so my symptoms have been blamed on that. With all these symptoms,
I sometimes wonder if it would be better off to have the hypertension.
Sometimes my mouth and throat is so dry and sore, I can't eat and I have difficulty breathing which is not addressed with asthma medication. Daytime symptoms are bad at night but when night time comes, it is almost impossible to sleep.
I would be interested if anyone has these symptoms and would like to hear from you.
