A new clinic that opened March 20 in the Gottschalk Medical Plaza at UC Irvine addresses one of the largest issues in healthcare – undiagnosed immune system-diseases in children and adults. More than half a million people in the U.S. and 15 million worldwide suffer from primary immune deficiencies. The Jeffrey Modell Diagnostic Center for Primary Immunodeficiency is one of the few clinics in the country dedicated specifically to providing diagnosis and care for those born with improperly functioning immune systems. It’s one of 50 clinics worldwide sponsored by the Jeffrey Modell Foundation and Grifols. “Early recognition and diagnosis of PI can save lives and improve health outcomes,” said Dr. Sudhir Gupta (pictured), center director and chief of immunology for UC Irvine Healthcare, who was instrumental in the center’s establishment.
