Relative Distribution of the PIDs

Slide 4

January 2010

The PIDs can be classified based on the component of the immune system that are affected - these include humoral or B cell defects, T cell or cellular defects, phagocytic defects and complement defects. The humoral or antibody deficiencies account for the majority of the PIDs, ~65%, while "pure" cellular deficiencies account for only 5% of the total cases of PIDs. The combined cellular and humoral immune deficiencies account for another 15%, while the phagocytic and complement deficiencies account for the remaining 10% and 5% respectively.
