Hello @adah, welcome to Connect. I have no medical training or background but have read that if your immune system makes low levels of antibodies, you may have a greater chance of developing repeated infections. There are some good explanations of the tests here:

Hi John,

Just wanted to mention a warning for all. Last Thursday was my birthday, so I got off my good diet by eating large portions of 2 very, very rich birthday cakes and drinking wine. After being of prednisone for over 2 weeks, had to take some this morning. I have PMR and the worst culprit for all inflammatory conditions is SUGAR.

@adah, May I ask why you are asking about IgA IgG and IgM antibodies? Are you and your doctor investigating a particular diagnosis?

Yes the dr is looking to see if my relative has cirrhosis or an autoimmune disorder

I have very low levels of IgG and was diagnosed with Common Variable Immune Disorder (CVID). I have been receiving IgG infusions for about 10 years now. For many years they worked very well and symptoms were greatly reduced. Unfortunately, for the past two years, my symptoms have increased. I do not have the most typical symptoms of chronic/frequent infections but rather less common digestive problem of daily episodes of vomiting and diarrhea. I would like to hear from others with CVID and learn from them what has helped and of course share what I have learned. My IgA is also low but I was told that it is of no concern as some people have no IgA.

@mightmouse — I'm tagging @ldestella @xfirerose and @cbdonlon who have discussed CVID in other discussion to see if they are able to offer any suggestions or information for you on CVID and what has helped.

@mightymouse1945 What is an IgG infusion? What exactly do they put into your body?@

Immunglobulin G is infused via IV into your blood stream. Mine is done at a cancer treatment center where people receive chemotherapy IV infusions. IgG is part of your immune system. It is a blood product. It has made a huge difference in my life. I use to have daily episodes of cramping, vomiting and diarrhea lasingt 3 to 4 hours. IgG infusions have very greatly reduced my symptoms. There are medical articles on the internet which can better inform you about IgG and CVID..
