Katie, do NOT get discouraged!!!!!!! That's an order!!
As to that tryptase, there are very few other disorders which will elevate a tryptase, so the field is very small as to what they can be. Granted, your tryptase is in the " normal" ranges, but one of the scientists from Harvard who I've been speaking with for over a year now told me himself that NORMAL people do not have a tryptase which goes over 0.9ng/mL. He is doing research on MC mediators and MC involvement in other pathologies and he told me that aortic aneurysm patiens won't have their tryptase rise above 2.5ng/mL. This information really helped my doctors for we are investingating all of my children for masto. The information we are gathering is proving to be very illuminating.
My case is a proven MCAS and it's a suspected MMAS. The profile for the MMAS patient is KNOWN to have normal tryptase levels. Mine is 4.6ng. We have proof of raised histamine levels, as well as other pathological damage which runs in line with masto behavior. So, in gathering all these clues and exluding all the other diseases my doctors have NO DOUBTS that I have mastocytosis in some form or another.
In looking at my eldest son's case, we have found the MC aggregates, which in my case we have not yet found them. There is NO OTHER disease which causes the MCs to clump, only systemic mastocytosis. Since masto is a genetic disease, my son got his from whom do you think?! Which paints more of my own cases picture. We're still in the initial investigation of my son's case, but his tryptase is lower than mine - 2.6ng/mL. But there is NO DENYING that he indeed has masto - we found the aggregates and that's concrete proof of the disease. Can he be diagnosed as SM? No. He does not fulfill the criteria for SM. So his diagnosis is MCAS - like me.
In looking at my 2nd son's case, he is also in the preliminary process of diagnosis and it may be YEARS before anything can be specifically determined. He is showing the very same autoimmune markers that I have - raised ANA of 1:320, hypothyroidism and a tryptase of 5.5ng/mL - higher than mine!!
My daughter has just begun testing and we're waiting upon her tryptase.
My doctors are looking at my children through the shadows my case casts upon theirs. Although my 2nd son's tryptase is 5.5ng/mL he has flushing and is sensitive to smells and heat and has gone through what we now feel were 3 episodes of anaphylaxis.
Although my masto specialist knows that she can't openly diagnose either one of my sons with mastocytosis, she knows that this is indeed what we are working with. She has no doubts and has put both of my sons on Ketotifen.
Kate, obviously Dr. Bernstein is not his father and you've run the end of your line with him. This lets us know where he is regarding masto.
A doctor who KNOWS masto will no longer put all of his trust in tryptase results for they are finding that depending upon the form of the mast cell disorder, the tryptase will not be elevated. And as according to the scientist at Harvard, anybody with a tryptase above 1ng/mL has something going on with them that has their mast cells releasing tryptase. However, what is the question. Like I said, aortic aneurysms will raise tryptase as high as 2.5ng, and I believe that multiple myeloma will also raise tryptase, which is why they set the range for systemic mastocytosis for being 20ng, for no other pathology raises it consistantly higher than that except when a patient is in anaphylaxis. But the issue here is finding out what has your tryptase above 1ng/mL?
With your symptoms, Kate, which is what Dr. B wasn't considering, it is most likely a mast cell disorder. What form is the question.
Kate, if I remember correctly you had been speaking with Dr. Akin. He's a lovely man, Kate, and he's fully understanding what Dr. B isn't getting. Please write to him and ask his advice and if he would be willing to see you. GO TO DR. AKIN!! He KNOWs that depending upon the timing and the form of masto that you may not show positive markers, but you could also be IA and that's a group of patients who don't show anything!!!
So, since you have already spoken with Dr. Akin, knock once again on his door and tell him what you are going through and ask for his help!! I feel confident that he will answer you and open up the door for you.
I hope this helps!
