Jason Catanzaro, MD, specializes in treating children with allergic disorders or primary immunodeficiencies, or when a patient’s immune system is not acting normal. These are usually caused by a genetic defect.

“I enjoy helping patients understand their condition and providing them with treatment options,” Dr. Catanzaro says. “What’s cool is helping kids feel better, whether it’s preventing or stopping infections or helping with allergies so they can play sports or enjoy the outdoors.”

Treatment options Dr. Catanzaro offers include allergy shots or immunoglobulin replacement therapy, a blood-based treatment to boost the body’s natural antibody levels and fight off infection.

Dr. Catanzaro’s research focuses on how the immune system works and collaborates throughout Yale to help answer questions that families have.
