IgA Deficiency Support Group

Selective immunoglobulin A (IgA) deficiency is a relatively mild genetic immunodeficiency. People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract. It is the most common of the primary antibody deficiencies.

    Do people really see a huge improvement post infusions? How long did it take to show a change?I am constantly ill with infections and unable to be placed on a low dose antibiotic for IgA deficiency due to recurrent cdiff.
  • This is an instructive post for those of you with an IGA deficiency that don't know what to do.  I'm an older guy, and all my life have had recurrent respiratory infections,  sore throat, virus, gram negative bacterial infections, swollen glands, and easily get sick with an average of four to six weeks between illnesses.  When I got sick -- it came on fast -- in a matter of hours -- and before...

    Anybody with autoimmune issues?

    I'm curious if anyone in this group has autoimmune issues in addition to the immune deficiency. I know this is common with CVID, but I'm wondering how the 2 interact with a selective IGA/IGG subclass deficiency. I also have hashimoto's which is an autoimmune thyroid disease. I find it's difficult to distinguish which health condition is responsible for the various symptoms I have.I'm trying to...

    Iga deficient then not defient?

    I was diagnosed with Hashimoto's 2 years ago. I was ready to start making a change to my diet and was seeing a Naturopath and because of some abdomen pain she suggested I have testing done for Celiac. I had blood work done where they checked my IgA and IgG levels. IgA came back at .5U/mL and IgG came back at 50U/mL so one negative and one positive. The dr said I needed a biopsy to confirm if...

    Hi, Today I got my blood test results showing IgA 19, my Doctor mention something to do with bacterial infections and also mentioned bone marrow, my doctor said I must have had a virus in the past to cause my low IgA.  Could someone please give me some information on low IgA as I do not know what to think, I would be so grateful.

    IGA and IGG subclass deficiency?

Is anyone receiving IVIG to treat it?I was orginally diagnosed with CVID because my total IGG and IGG subclasses were below normal in addition to IGA deficiency. I also have Hashimoto's (an autoimmune thyroid disease). My IGG went up, so my dx was changed to selective IGA with IGG subclass deficiency. My doctor is still...
