Hi deb ,
I understand your comparision now
. I have had ataxia ( no back based cause ) , feeling drunk without alcohol
and have very sleepy episodes where I can't wake up . The sleepyness may have an adrenal cause as i am secondery hyopadrenic. The others await expination .
But I am having sleepiness , paleness and shaking with functional doses of steriods and on high doses . My BM has been fine . So not hypo ( low sugar ) . I am diabetic
So I am suspecting mast cell activity , more in my bones as i have shoulder and hip pain when i am like this .
Siezures are seen in 2% of anaphylaxis episodes , assumed to be due to low oxygen levels as brains need oxygen , they can not function without it . Other organs can for a period of time .
It is therotetically possible that mast cell stimulated inflammation could cause problems . But I am not aware of mast cells in the brain or the meningies . But menigitis / encephalitis is an inflammatory process so I would not be surprised if they are discovered . Compliment is smaller molucles so it could pass the blood / brain barrier .
Histamine itself is known to have recpetors in the brain so it is possible histamine from mastocyctosis could stimulate these receptors . It also acts as a neurotrasmitter . So has a role in nerve conduction .
So it is plausable that your sons neurological symptoms and inflammation are being exacerbated by histamine and or compliment pathways both in his brain and else were.
Any inflammation in my body leave me open to anaphylaxis ( IGE ) and anaphylactoid ( other routes to mast cell activation ) reactions . I am most likely to go off in spring when sniffig a cat and hoovering xxxxxxxxxxxxxxxxxxxxx my IGE allergies are cats , grass and house dust . IN my situation these allergies are amplified as my mast cells are over sensitive . making me react a great deal more than I should .
Trigger wise you are not unusual here
.I trigger with sulphites , alcohol , fermented foods , food colouring ( very bad ), gelatine , corn ,heat , infection , hormones , CT contrast .
Certian anesthetics are known to activate mast cells , as are some other drugs .
I take it you and your son ahve been worked up for autoimmune possibilities
. Those which are most pertinent are Lupus . But also thyroid ( hashimotos thyroidosis ) as a source of swelling ( angiodeama ) and autoimmune addisions ( adrenals , leading to low levels of hormones inc steriods which can cause angiodeama and other problems )
With a strong family history , heridatory angiodeama may be wise to be screened for ( compliment levels ) . mastocytosis is possible and i am glad you ahve an appointment soon . If you and your son are not positive for masto . You may have mast cell activation syndrome , MCAS which presents with similar symptoms but not the criteria for masto as set out by the world health organisation . MCAS has been accepted by who , but is undergoing discussion of daignostic criteria .
There are some vids on you tube made by the masto doctors which you may find helpful xxxxxx they are called mast cell activation symptomology
Any biopsies you son has had may be useful to the docs as they may beable to re examine them , knowing what they are looking for
A list of procedures and the date and hospital will grately help the docs
I am going through the process of writing my own list as I have finally got to docs who have diagnosed me with angiodeama - swelling of hands , feet ,bowel , face , mouth , tounge and inside my throat
Now I am awaiting results of if it is a new type of heridatory angiodeama , type 3 , there is no one test as its new (2006 ) but a mix of tests . if its not that it will be histamine . I am not looking like its masto . More mcas . But these are the decisions my docs will make soon . I want them to re examine samples from my bowel to see if I have mastocytic entrocollitis , which is the cuurent name for mast cell collitis . mastocytosis can only be diagnosed from skin or bone marrow biopsies and the size and type of mast cells .
But there are patients , who do not have bone marrow or skin classifications but have problems with mast cells elsewere . either a normal number over reacting to silly things , like vinigar in cleaning products . or extra mast cells in different areas . These may fall into the new criteria - MCAS . Or may remain labeled idiopathic anaphylaxis if they don't fit the criteria but have anaphylaxis with no identifiable cause .
I can imagine your daily life is very challenging . I can hear your determination and love for your children and know you will strive to find what is , for many of us , a very welcome but long sought for answer .
many hugs
josie
