Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
I would also get huge fluctuations in weight gain on hizentra along with swelling , a rash and cough , rapid HR and wheezing and shortness of breath .That was stopped immediately . It sounds like you had fluid overload ? They stopped my infusions and changed brands. It seems with every infusion the stronger the side effects . Not tolerating this one as well this month thats for sure as I sit here shivering . I have been on it one year.
Are you IGA deficient as well? Hope you get this sorted out so you can feel better soon . I am continuing to monitor ,and chart and will talk with my Dr about pre meds or slowing down the rate
