After 3 back to back hospitalizations in 2017 with chronic pneumonia each time, tests were finally done during my last stay in August 2017 by my hematologist. It was at that time that I was diagnosed with having basically no immune system which caused me to have reoccurring bouts with pneumonia. As of 2017, I had had pneumonia resulting in hospitalizations every year since 2013. However with the back-to-back occurrences in 2017, I was happy to at least finally have a diagnosis. I began having IGIV infusions in 2017 and thus far I have remained pneumonia free. I am grateful for this website and all the helpful information that has been shared with me since my diagnosis.
