Mast Cell Activation Syndrome (MCAS)

hi, thanks for responding guys, as you mentioned MCAS diagnostic is quite hard and i posted a question here not because of my laziness, though i am ;), but because even that i put a good few hours into research, still there are no straighforward diagnostic route, so depending on the article/opinion you can get contradicted answers.

i probably need to visit an allergologist but since mcas is so hard to diagnose + it's rare, i'm a bit hesitant about doing it, because i would need to pay for it from my own pocket and i'm pretty sure, that it will be another usless and frustrating visit and at most i will get information, that i can google myslef in 3 minutes, but who knows ;)

@Jyoti your idea with just testing anti-histamine otc drugs seems reasonable- it's safe, easy, cheap and gives a quick answer, even if those drugs dont address core problem, they may improve the quality of life. The only thing that bothers me a little bit is that if anti-histamine_diet/avoiding_of_mcas_triggers are not giving any substantial difference, is it possible that some positive results from anti-histamine drugs, in your case, are due to not 'pure anti-histamine effect' of them but some other things- f.e. anti-inflamatory effect or whatever other reason- just by opening wikipedia page on h1/h2 receptor antagonist you get multiple ways that they affect body- we don't know if you don't benefit from any of those.
I'm thinking that trying anti-histamine first and after a break from them, trying mast cell stabilizers like cromolyn sodium, high-dose wit-c or quercitin that you mentioned, might be even better, because getting positive reaction from 1st group and than getting positive reaction from 2nd group is far more probable indication of mcas, than just trying drugs from only of those group. Getting positive result just from one group and none from other may idicate that results come from some random effect of those drugs, rather than addressing mcas.

According to my resarch thing that might be worth trying is also trying supplementing copper and see how we react- according to studies, if it is depleted we might have problems with mcas/dao + few probiotics might be also helpfull, Lactobacillus rhamnosus GG seems promising (cheap, safe, ...)

I've tried liposomal quercetin, which relived my chest tension a way better than normal quercetin because of better absorption, which didn't do anything at all anymore.
But I got heavy overstimulated and inflammation evolved days after, turning the effect into opposite direction.

I observed the effect of early improvement with worsening in the end with most herbs, especially with the bitter ones, so there must be another issue going on.

i got the same, i do not tolerate herbs at all. its a increasing effect, the long and more i take the worse it gets. making my asthma and allergy worse.

i believe this to be some kind of plant toxin which gets concentrated in plant extracts like the positive things too.
could be histamin(liberators) or salicylate or another unknown compound. but salicylate is for sure extremly high in plant extracts. so if aspirin makes you worse, that could be it. (and probably salicylate is a histamin liberator, adding double trouble)
but i do not know any cure for salicylate except not taking it. its worse than histamin. there we get at list h1-h2 antagonists and DAO.

Some of this is a repost of another thread, but I’ve added updated info throughout.

~~~

It seems that many people still refer to all aspects of Mast Cell Disease as Mast Cell Activation Syndrome. But to my understanding, MCAS is based upon allergic reactions triggering Mast Cell release.

My docs have diagnosed me with Systemic Mastocytosis as opposed to Cutaneous Mastocytosis, Mast Cell Activation Syndrome, or Hereditary alpha-tryptasemia. I was also told that out of the 5 Mast Cell subtypes, only two or three (I forget) can actually be tested for.



In July I went through a number of new tests, for me that is. I was having horrible “allergy” symptoms since late April. In the past number of years, my supposed “allergy” symptoms have been increasing in severity and duration, as well as would spontaneously flair up at anytime during the year, including the dead of winter. So, my main doctor referred me to the only allergy clinic in the state for testing.

I’ve had food allergy testing done before and know what foods are actual allergens, but my environmental panels always showed negative. I’m also allergic to many medications.

At the end of June, I had the full back skin grid done and every box turned out Negative. I was having “allergy” symptoms and yet the test showed I had zero environmental allergies, just like every time before in the past 12 years.

So, the allergist sent me to the lab for blood tests and a 24-hour urine collection test. He said he doubts I have this, but there is a very rare condition known as Mast Cell Disease, of which there are a few variations. He wanted to test me simply to rule it out. To his surprise, it came back Positive.

The following tests were run:

  • NMO/AQP4 FACS, S
  • Sed Rate
  • C-Reactive Protein
  • Leukotriene E4, U
  • N-Methylhistamine, 24 Hr
  • Tryptase, S
  • Prostaglandin D2 (PGD2)
  • KIT D816V Variant Analysis Quant, V

These came back as flagged and abnormal:


-N-Methylhistamine, 24 Hr came back high.

Normal range: 30 - 200 mcg/g Cr

Mine tested at 250


-Leukotriene E4, U
came back high.

Normal value is less than 104

Mine tested at 184.


-2,3-dinor 11B-Prostaglandin F2a


Normal value: <1802 pg/mg Cr

Mine tested at 2001


The Gene Variation test came back negative.


After multiple visits with three doctors in my healthcare team, based on all my symptoms, history, and test results they have confirmed a diagnosis of Systemic Mastocytosis as opposed to Cutaneous Mastocytosis, Mast Cell Activation Syndrome, or Hereditary alpha-tryptasemia.

Since July I have been on:

  • Fexofenadine – 180 mg 4x per day (2 in am and 2 in pm)
  • Montelukast – 10 mg daily in morning – this is a Leukotriene blocker
  • Famotidine – 40 mg in pm

Some of my “histamine-like” symptoms have decreased. Nasal, sinus, eye, skin, and ear itching have decreased by probably 90%. Insomnia is almost non-existent, and before it was nightly. My moods have increased as has libido… both are reliant upon dopamine levels, and my neurotransmitter tests (3 in the last 8 months), have consistently shown almost no dopamine, epinephrin or norepinephrine production… and HISTAMINE competes with and overrides Dopamine. So, that tracks.

Respiratory inflammation has remained the same, sadly.

As to my vision – I remain blind in the left eye and my right eye still has severe depressed vision capacity. My ophthalmologist wrote in my file:


…”has severe depressed vision, chronic. Left eye has NO usable vision. Possible vision return, unknown. Right eye has depressed peripheral vision of less than 40 degrees, depressed frontal vision, and at best is sometimes correctable to 20-40, but only when sitting or lying down at rest, not while standing or active. Much of the time though visual acuity is 20-850 with 20-200 being legally blind. Even with better acuity days the eye is prone to grey-outs, blur-outs, wavy underwater vision, double and triple vision. Mr… is and must be considered legally blind.

“Mr… has a remarkable ability to self-navigate and mostly normal function in his daily life

with such levels of depressed and absent vision. It is truly impressive to witness.”



On Thursday morning, August 28th, I had the worst GER (Gastroesophageal reflux) attack I’ve ever experienced!!! It was fucking horrific! Lasted a solid 3 hours. The pain was intense, easy a level 8, and I couldn’t even swallow spit. It felt as though there were an iron claw full of spikes crushing, twisting, and wrenching my lower esophagus that radiated throughout my entire torso. My wife thought she was going to have to bring me to the ER. My hands went completely numb from the body stress. My vision left to where I couldn’t see anything at all.

In the past year and a half, I’ve had a few small GER attacks that would last maybe 10 minutes. I didn’t even know what they were they were so mild and short lived. This year in late spring I had the first ever that lasted 30 minutes, but its intensity was ¼ of this one.

My one doctor said one of the most common symptoms with systemic mastocytosis are digestive. The time frame of the GER fits with the rise or development of the systemic mastocytosis, of which I was recently diagnosed with last month.

All day I was only able to eat a mashed mini cucumber with banana. Couldn’t stomach any of my medications or vitamins. All day I was brutally exhausted and spaced out. Respiratory system was also compromised, still. Body temp plummeted and I was chilled all day.

Slept the night through but was dehydrated.

Since then I have been exhausted, fatigued, burned out, spaced out and weak like I had the flu for a couple weeks. I’m trying to manage very small amounts of bland easy to digest foods; oats with pork gelatin, baby carrots, cucumber, banana, bok choy, weak herb tea, water… and if I eat really slow and just small amounts, I can stomach it. Afterward I do feel a hot slightly acidic feeling in my gullet though. Probably because my esophagus is swollen and healing from the chemical burn.

In the past 6 days I’ve lost 10 pounds. I stand 6 feet and typically weight 170 pounds.

I had an acupuncture treatment the day before the GER attack. That was the first acupuncture treatment in over a year and my healthcare team says it triggered a systemic mastocytosis episode, which gave rise to the GER attack the day after.



For me my healthcare team says the systemic mastocytosis seems to release mast cells that have mostly attack my entire respiratory system; lungs, bronchi, nasal passages, and sinuses. And now it seems to have expanded to my upper GI system and some regions of the skin.



On September 16th I have aa consult with my head doctor to pick his brain about all this. Though I've been living with this seemingly for years, the awareness of it and all that it encompasses is completely new to me.



As of this time my medically diagnosed conditions. All but one was diagnosed after specific testing and or images confirmed the conditions existence.

  • Severe Visual Handicap - neurologically caused
  • Hearing Loss
  • Dysautonomia/Postural Orthostatic Tachycardia Syndrome (POTS)
  • Myalgic Encephalomyelitis (diagnosed by 3 doctors but of course no verifiable diagnostic test)
  • Post-Exertional Malaise (PEM)
  • Post-Exertional Encephalitis (swelling of spinal cord after exertion)
  • Hypothyroidism
  • Hashimoto’s Disease
  • Neurotransmitter Dysfunction – Dopaminergic pathways
  • Chronic Complex PTSD – childhood abusive cult, torture, and combat related
  • Systemic Mastocytosis
