I'm in the UK and we have the National Health Service, however the dept do allergy too.
I don't have CVID, I have good antibody responses to vaccination.
They are now looking at lymphoproliferative disease and maybe x-linked lymphoproliferative disease. I don't think I have this either but it may be possible that I could have a mild form? What's interesting is that the trigger for x-linked lymphoproliferative disease is EBV with hypogammaglobulinemia. My illness started after a bout of EBV? I'm still of the opinion that my illness is caused by a smouldering EBV infection.
I've been taking valacyclovir for 12 months and I've tested for a slightly improved hypogammaglobulinemia and my energy levels have increased also over that time. I have a rash on my face what I like toi describe as an immature "Butterfly Rash", which is a dignostic fetaure of Lupus which has high ANA antibodies (I have low ANA antibodies). I have been using a hydrocortisone cream on it for 17 years and this now doesent need that cream but I do use every other day vasaline to stop the skin flaking.
I've also suffered less infections (colds etc) in the last year with their severity reduced also. Previously I would catch everything going and the severity would be greater than others.
