I also have common variable Immunodeficiency ,(CVID) as well as MAC. I tried the 3 antibiotics and was not able to tolerate two of them. So I was discontinued. Now my lungs have gotten much worse. My pulmonologist is referring me to UCLA for treatment. I have also developed Bronchiectasis from the MAC infection. I do not know anyone with CVID. Does anyone on this discussion have CVID?
