I had similar situation. I do at home ivig infusions. I also have MAC now which I contribute to having low titers for pneumonias/ staphylococcus and streptococcus, probably for all of my life but just now diagnosed with SAD. Specific Antibodies Deficiency. Go figure! I have not been sick in 9 mos...
Just diagnosed with Breast Cancer tho...ughhh, when it rains...grab that bumbershoot!!!

@clynnford That's great you have not been sick in 9 months so the IVIG must be working. Bummer about the breast cancer...wishing you a speedy and successful treatment.

I may be wrong but encapsulated bacteria like pneumonias, staphylococcus and streptococcus are different than NTM/MAC. Low antibody titers might make one susceptible to bronchiectasis through frequent infections. Bronchiectasis might make one more susceptible to NTM/MAC infections through ubiquitous air, water [pipes] and soil.
