After multiple hospitalizations in 2016 with pneumonia, sinusitis and asthma each time, doctors couldn’t understand or explain what was wrong with me. Finally, after a year of recurrent respiratory infections, one of my doctors decided I should see an inmunologist. After many blood tests were done. I was diagnosed with Specific Antibody Deficiency (SAD) on January 2017. I started IVIG infusions ever since and and I have gotten less infections than before and it has also helped me to have a better quality life.
