Introducing Cook Children's Immunology department

Treating kids with immune deficiency disorders

Consultations and Referral

If your child's immune system doesn’t work properly, it can cause problems like severe, frequent or unusual infections and autoimmune disorders. That's why Cook Children's Immunology team is dedicated to providing excellent, patient-centered care, as well as access to the most up-to-date therapies and leading-edge clinical research for all types of immunologic disorders.

Our team provides a broad range of services including diagnosis, inpatient and outpatient consultations and immune deficiency evaluations.

What is immunology?

The immune system is the body's natural defense against infection, and immunology is the study of the immune system. Our immunology team evaluates, diagnoses and treats children who were born with errors in their immunity system, also known as primary immune deficiency disorders (PIDDs). There are more than 450 of these conditions. These patients are at risk to serious infections and illnesses. Some of these conditions can run in families and be passed from generation to generation.


As a patient of our Immunology program, your child will receive an evaluation and treatment by our board-certified doctor in immunology. Our team provides consultation for the management of:

  • Primary immune disorders
  • Immune dysregulation disorders
  • Hematopoietic stem cell transplantation
  • Abnormal newborn screen

"It's exciting to be able to create an amazing program that will fill a definite void. Problems with the immune systems are really, very rare, and unless someone thinks about them or considers them as a possible diagnosis, they are missed. This clinic is an incredible opportunity for earlier diagnosis, which will lead to quicker intervention and treatment."
Dr. Natalia Chaimowitz

Our team is available to provide information, education and resources to help learn more about your child's condition and treatment plan. In addition to being cared for by our immunology team, we partner with many specialists across our system, including those in:
