Program Description

As a NIAID clinician, my main focus has been on the diagnosis, evaluation and management of individuals with defined and undefined primary immunodeficiencies (PIDs) with a particular focus on those with hyper IgE syndromes. STAT3 mutated Hyper IgE syndrome (STAT3 DN; Job’s syndrome) is associated with eczematous dermatitis, recurrent boils, recurrent sinopulmonary infections, and multiple connective tissues, skeletal and vascular abnormalities. This is a rare primary immune deficiency, and our center allows us to study the largest cohort in the US, and likely in the world.  We currently follow more than 100 individuals with STAT3 DN and provide clinical care to many when well and during acute illnesses.  Through laboratory collaborations over the years, we have sought to understand STAT3’s role on human immunity, airway infection susceptibility and wound and vascular remodeling. Although our understanding of the pathogenesis of STAT3 has increased in recent years, there are still many unresolved questions regarding the pathogenesis of the varied features and the optimal therapies, including the role of hematopoietic stem cell transplantation and gene editing.
