Transition and Adult Immunodeficiency Program

Cincinnati Children’s is a worldwide leader in the diagnosis and treatment of primary immune deficiency diseases. More immune deficiency diseases are now being recognized in adults, and children with primary immune deficiencies eventually need to transition to adult care providers. To fill these important care needs, Cincinnati Children’s now offers specialized care for adult patients. The Transition and Adult Immunodeficiency Program collaborates with adult sub-specialty services at the University of Cincinnati and will be offering services through the University of Cincinnati within the next year. 

How We Are Different

Our Transition and Adult Immunodeficiency Program focuses on the complex need of adults and adolescents with primary immune deficiencies. All of our physicians have received advanced training in the field of primary immune deficiencies and have special expertise in these disorders. We work as a team with the dedicated sub-specialists, such as the rare lung disease team at University of Cincinnati. We also benefit from the immunodeficiency expertise at Cincinnati Children’s including its Diagnostic Immunology Laboratory, which offers comprehensive testing for the diagnosis and monitoring of patients with primary immune deficiencies.

Conditions Treated

There are over 350 genetic causes of immune deficiencies, and the list continues to grow. A list of the more common diseases seen in adults includes:

  • Common Variable Immunodeficiency (CVID)
  • X-linked agammaglobulinemia (XLA) and other forms of agammaglobulinemia
  • Specific antibody deficiencies
  • Chronic granulomatous disease (CGD)
  • LRBA deficiency
  • CTLA4 deficiency
  • DiGeorge Syndrome
  • Many more


We are actively involved in basic, translational, and clinical research to understand the mechanisms of different immune deficiencies and how they may change over time. We are working to find new treatments and cures for primary immune deficiencies. Our research efforts are only possible with the support and involvement of patients.
