What are primary immunodefiencies?

Primary immunodeficiency disorders (PIDs) form a group of rare disorders that vary widely in severity. Those at the mild end of the spectrum can predispose infants and children to frequent minor infections, while the more severe ones lead to life-threatening infections and other life-limiting complications. In some cases the deficiency resolves with increasing age, but in most cases these are lifelong disorders that require treatments to prevent infections and treat other complications, and in some cases need aggressive treatment to correct the underlying problem.
