New PI Center Opens Raising awareness of primary immunodeficiencies Rainbow now is one of only 25 centers in the world focusing on the diagnosis, care and treatment of adults and children suffering with primary immunodeficiencies (PI) through the Jeffrey Modell Diagnostic Center for Primary Immunodeficiencies at Rainbow Babies & Children’s Hospital. The new Center, headed by Rainbow allergist and immunologist Melvin Berger, MD, was made possible this spring thanks to the Jeffrey Modell Foundation, in partnership with global biotherapeutics leader ZLB Behring. This new partnership reaffirms a commitment to raise awareness and increase diagnosis of PI globally. The Center at Rainbow also will serve as a resource of expertise in the subcutaneous administration of IgG (antibodies that PI patients cannot make themselves), an alternative to intravenous IgG, which was introduced by Dr. Berger.
