Hi @kpost2 I would like to share with you this article that details the clinical uses for IVIG infusions: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1809480/

That must be frustrating to feel that your pulmonologist and allergist don't listen to you. Have you felt comfortable asking them how long you will be doing this treatment?

Hi there @kpost2. Your statements in your post sound like you are unsure of your treatment or lack trust in your healthcare providers. If that is the case, you may want to consider getting a second or third opinion. If that is the case; If it were me, I would go to the nearest medical institute for help. May I ask what state you live in?

@kaypost2 Hello. I found a link about low IGg that is very informative and an easy read. I have read it. In the first or second paragraph, it states that Immunodeficiency can be easily misdiagnosed (and difficult to diagnose). It also says that if you are in a consistantly low range; gives options for treatment. After you have read the link, will you add your thoughts about your situation? https://primaryimmune.org/about-primary-immunodeficiencies/specific-disease-types/igg-subclass-deficiency

Well, that is one very interesting article. Thank you Terri. (Irene5)

Hi. After MAC diagnosis, I had immunology tests, and discovered my IgG was low–below ref range. I was started on Hizentra weekly infusions about a year ago, which I administer myself subcutaneously, and now I test in normal range for IgG. HIzentra is IgG from pooled blood sources. I used to shiver a lot and had to take hot baths in afternoon to stop. Now the shivers have gone away. Docs don't pay any attention to my report of shivers, but nurses say lots of MAC patients have them. I also do not get as many Upper Respiratory infections. Note– I did not have terribly low IgG, and a second immunologist said she would not have prescribed the HIzentra. It has made my hair thinner (I blame it anyway). And it has goofed up an annual test I do which is a biomarker for a certain type of thyroid cancer because I now have thyroid antibodies — so I will go off Hizentra for a month to do the test.

@clpc That is interesting stuff. Please keep me posted on whether they put you back on it and if your thyroid antibodies straighten up. We have several members in our group who are also experiencing immuno-deficiencies and got mac. I will see if I can connect them to you.

@clpc, Hello. Bad as it can be, I find the low IGg stuff interesting. Some patients that have mac have the low IGg. I wonder what causes that? Will you please keep me posted on how you are doing? I hope your thyroid antibodies straighten out.

Hi. I have cvid and treat weekly with subq ig . My treatment is for the rest my of my life since the iig gets used up. Unfortunately, my immune system won’t heal. I have been treating for. 3 yrs this coming Jan. It has helped tremendously with infections. I don’t get sick as often and have not needed I’ve antibiotics to get better. I also have mac. I have not noticed any hair thinning.

@bennb023 I am so glad that you are doing well on the IV treatment. Does that alao help ro keep the mac at bay?

I live in Nebraska. I have an Appointment today with my Allergist. She is the one that my I.V.I.G. treatments are with.

I really recommend Hizentra that you can give yourself once a week. You get smaller dose at time than IVIG but then you don’t get much reaction

She mentioned Hizentra yesterday also. She sent me a video about it to watch. Haven'[t watched it yet.
