Immune Matters: a PIDTC Podcast

Jack McDonnell

Join Jack McDonnell, MD, a pediatric immunologist and assistant professor at Cleveland Clinic Lerner College of Medicine, and  Elie Haddad, MD, PhD, a clinician-researcher in pediatric immunology, full professor at the University of Montreal, and head of the Immunology and Rheumatology department at CHU Sainte-Justine, as they explore the evolving world of immune deficiency and dysregulation. Presented by the Primary Immune Deficiency Treatment Consortium (PIDTC), this podcast features conversations with leading experts, pioneering researchers, patients, and advocacy groups. Each episode uncovers cutting-edge research, clinical challenges, and personal stories—ensuring that the patient voice remains at the center of the discussion. Whether you're a clinician, researcher, patient, or advocate, Immune Matters brings you the latest insights in diagnosis, treatment, and innovation in primary immune disorders. Tune in to explore the science, the stories, and the future of immune health.

    PIDTC Immune Matters - Episode 5 Emapalumab

    In this episode of Immune Matters, hosts Jack McDonnell and Elie Haddad speak with Dr. Joseph Oved, a pediatric hematologist-oncologist and transplant specialist at Columbia University, about the biologic therapy emapalumab (Gamifant). The discussion explores how this anti–interferon-gamma monoclonal antibody is used to treat hyperinflammatory conditions such as primary hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome. Dr. Oved explains the underlying immunology of interferon-gamma–driven inflammation and how targeted blockade of this pathway can interrupt the cycle of immune dysregulation. The conversation also examines emerging applications of emapalumab in hematopoietic stem cell transplantation, including its potential role in preventing graft rejection, managing hyperinflammation, and improving transplant outcomes in patients with inborn errors of immunity. The episode concludes with a discussion of ongoing research, the importance of precision medicine in immune dysregulation disorders, and new PIDTC initiatives that allow clinicians to collaborate on complex cases and share expertise across institutions.

    Immune Matters Episode 2, Jen, Chronic Granulomatous Disease

    In this episode, Dr. Jennifer Leiding, a pediatric clinical immunologist, discusses Chronic Granulomatous Disease (CGD) with Jack and Elie. CGD is an inherited immune deficiency that leads to severe infections and autoimmunity. She explains the dual nature of immune deficiency and autoimmunity in CGD patients, the role of transplantation as a treatment option, and the expectations for families receiving a CGD diagnosis. Dr. Leiding also shares insights from her research on CGD, the complexities surrounding the concept of a cure, and the emotional burden faced by families. The conversation touches on the potential of gene therapy as an experimental treatment and highlights the often-overlooked symptoms experienced by carrier mothers of X-linked CGD. Overall, the episode provides a comprehensive overview of CGD, its challenges, and the ongoing efforts to improve patient outcomes.
