Hi jennifer
Welcome to our forum
You are not alone
I am in a very similar position but ahve moved a bit further forward than you
Tryptase ;- This is very hard to catch high , only 30% of all anaphylaxis show high tryptase . So a high is useful but a normal does not mean its not anaphylaxis
There are several causes of angiodeama , not just histamine , and I wander if you have been tested for these . HAE - heridatory angiodeama , autoimmune agiodeama from lupus , thyroid , adrenals , and histamine .
HAE - compliments - C1 , C3 and C4
Lupus - ANA , C2
Thyroid - free T3 T4 and thyroid peroxidase enzymes
adrenals - adrenal antibodies and 9 am cortisol ( off steriods ) don't do this until you ahve other treatments .
histamine - tryptase , 24 hour methyl histamines and prostoglandins .
I ahve idiopathic angiodeama
I have lip , tounge and inner airway swelling , dizziness and fast heart beat , in a serious reaction .
Your doctors are wanting evidence of a typical anaphylaxis , you may never give them it . You are however having angiodeama which is affecting your airway . This is classed as idiopathic anaphylaxis , as per the protocol designed by Dr green burger .
Classification of Idiopathic Anaphylaxis (IA)
(Adopted from Roy Patterson, M.D. textbook on Idiopathic Anaphylaxis)
Disease Symptom
Generalized (G) Urticaria or angioedema with bronchospasm (asthma)
Hypotension (reduce blood pressure), syncope
Angioedema (A) Angioedema with upper airway compromise
(Laryngeal, pharyngeal, tongue)
Frequency of episodes More than 6 episodes per year: Frequent (F)
Less than 6 episodes per year: Infrequent (I)
Summary of Diagnoses IA-G-F, IA-A-F, IA-G-I, IA-A-I
Variations of IA Diagnoses
Corticosteroid dependent
IA- (CSD-IA) Applied when patient is controlled by prednisone but has recurrent episodes of IA below a threshold of prednisone.
Malignant IA (M-IA); Applied when patient requires high doses of prednisone to control IA. The dose is arbitrarily set at 30mg daily
Or 60mg on alternate days but much higher doses may be required.
IA-Questionable (Q) Applied for a patient with possible IA where Documentation of objective findings is unsuccessful and diagnosis is uncertain.
IA-Variant (V) Applied when symptoms of IA vary from classical IA.
IA-V may subsequently be classified as IA-I, IA-G, IA-Q or USIA
Undifferentiated Somatoform IA (USIA) Symptoms mimic IA but no objective findings are documented and the symptoms are not responsive to the regimen of IA.
For several years steriods have been used as the controling mediaction . More recantly new meds have come out which can stabilise the condition
I was where you are last year . I am now off steriods day to day and going to ed every 3 months ish , as compared to every 3 weeks .
Pimidine has alcohol as its preservative and I couldn't use it as alcohol is a major trigger for me .
I will list my meds so you can get a feel for where I am at now . I think You are under medicated sweets .
Am :-
ranitidine 300mg
ceterizine 10mg
piriton 4 mg ( same as clomitron ) drug :- chorpheneramine mealate
hydrocortisone 10mg ( adrenals not working )
hydroxizine 25mg
oxycodone 15mg
paracatamol 1g ( tylenol )
cyclizine 50mg
Inhaler - symbicort 200/6 - slow acting albutarol class drug and steriods
Lunch :-
paracatamol 1g
piriton 4mg
Tea
paracetamol 1g
piriton 4mg
8pm :-
oxycodone 15mg
Ranitidine 300mg
singulair 10mg
piriton 4mg
hyroxizine 25mg
cyclizine 50mg
Bed
paracetamol 1g
I was having daily throat tightenings and abdominal symptoms , until singulair and ranitidine was added . I have been on hydroxizine for a month and it has helped my brain fog and cysytis so much .
Its spring , pollen is not good for me . I ahve been in ED , 6 times the first year in march and april and 5 times last yr in march and april all with epi pen level reactions .
So far , cross fingers and everything else , I have not been to ED , YET , and its mid April .
Pollen is a problem to me , but it needs other triggers to make me ED level
In IA / mcas (ill expain next ) , we have a collection of normal mast cells which are behaving badly .
We may have a tryptase rise , but only in a short time frame in a serious reaction . 1-2 hrs post onset of symptoms . So catching it is hard . thats what the other tests are designed to do .
MCAS /MCAD , is a new diagnosis , which is having its diagnostic criteria honed down . It is where people have all the symptoms of mastocytosis but don't fit the criteria . The drugs are the same .
mastocytosis has extra , mishapen mast cells in clumps , in skin and bone marrow , which misbahave and burst with triggers . With so many extra cells , to release tryptase , it is higher in general terms and/or in a reaction . This is called clonal .
There is one exception , mmas , which is monoclonal mast cell activation . This is where there are extra mast cells but not enough in big enough clumps to be mastocytosis . these patients will ahve a normal tryptase
So as you can see there are 2 types of mast cell disease which do not show high tryptase . Most doctors do not know this. I have a paper about this if it will help .
Triggers are common to all of these conditions inc HAE . Pollens are a common trigger . people with mast cell disease can ahve true allergies as well , shown by high IGE in their blood . As a group we must NEVER come off our antihsitamines for testing , it is dangerous .
There is an article in the triggers section by Deb , our forum lead , which will help . Controlling triggers is central to managing this
Mine are sulphites , alcohol , vinegar and anything fermented , stress emotional and physical , infection , hormones , heat .
For the time being , whilst you find a mast cell doctor . There are 3 things to do doll ;-
Suss your triggers and avoid avoid avoid
use the low histamine diet :-
www.urticaria.thunderworksinc.com/pages/lowhistamine.html keep a diary , of foods , lotions and potions and meds , and your symptoms , i sussed so many of my triggers this way
xolair , will work , if you have a IGE allergy . There are several routes to mast cell activation known and many not and IGE is only one . So it may work , but may not .
Singulair works by blocking leucotrines found in the lungs . I have found this has helped my airway swelling considerably . I was blue all the time when walking , I am much better , only blue if I exert myself , and far less so . It has also helped my general swelling , legs and hands in particular . It works regardless of the cause of swelling
The drug groups used for mast cell angiodeama , are :-
anti histamines :- type 1 drowsy - benadryl (us ) piriton UK ( clomitron ), ketiofen and non drowsy - ceterizine and allegra .
Type 2 - ranitidine
lecotrine inhibitors :- singulair
mast cell stabilsers :- gastrocrom and ketiofen
I am not on a mast cell stabiliser yet , its my next step .
My doctors are also struggling to diagnose anaphylaxis . I have had 26 Epi pen level reactions. I think yours need to know that anaphylaxis is possible without a tryptase rise . Mine are open to having proof .
When you are swollen , I think an adrenaline nebuliser would be useful . NO alcohol
I have had this when I have not had any systemic symptoms - dizziness , high/ low pulse or high / low blood pressure .
I completely understand where you are at sweetie
I have been there with a stridor xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
I also have rebounds in the days post a biggie . It takes me a week to recover from each dose of adrenaline .
Ive got so much to chat about
Ill stop there for now
Many hugs
