Hello everyone. I tried antihistamine (desloratidine 5mg) and the muscle weakness and brain fog were gone.I was almost normal except for feeling sleepy. I was able to remember things but I felt very sleepy (which is a side effect of anti histamines). I have tried anti inflammatories and they too helped me (brain fog, muscle weakness were gone and I felt normal). I strongly feel that allergy to our reproductive secretions may be the cause for POIS. I come to know from this topic that antihistamines do not work for everyone. I do not know what causes POIS in those persons. But, in my case I strongly believe that allergy (Type 1 hypersensitivity reaction) is the cause for POIS.
To say allergy is the cause for POIS,we should check our Serum IgE (Immunoglobulin E) level. I also kindly request those, for whom antihistamines did not work, to check your IgE levels. Immunoglobulin E triggers Type 1 hypersensitivity reactions by causing histamine release and histamine triggers production of inflammatory mediators.
I checked my IgE level and it was 350 IU/ml ( normal value for adults is <190 IU/ml ).
I have copied a quote from my textbook about allergy (atopy or type 1 hypersesitivity reaction). The quote is as follows.
" Predisposition to atopy is genetically determined, probably linked to MHC genotypes. Atopy therefore runs in families. What is inherited is not sensitivity to a particular antigen, or a particular atopic syndrome but the tendency to produce IgE antibodies in unusually large quantities. All individuals are capable of forming IgE antibodies in small amounts, but in atopics IgE production is markedly high."
I think I have inherited the gene to produce markedly increased amount of IgE. But unlike my parents, I have developed type 1 hypersensitivity against my reproductive secretions. After type 1 hypersesitivity reaction has been triggered , the other type of hypersensitivity reactions like type2,3 or 4 can accompany. This means that different type of hypersensitivity reactions can co-exist.
If you are interested to read about different hypersensitivity reactions, read this textbook " Pathological basis of disease" by Robbins and cotran 8th edition. Read topic "Hypersensitivity reactions" in chapter 6 "Diseases of immune system".This is a standard book used by medical students. There are pdf versions of the book available in the internet.
