Abstract

Investigation of immune function is essential for accurate diagnoses in patients with recurrent and/or unusual infections as well as those with features of immune dysregulation. Many new diagnostic tools have been added to our medical armamentarium in recent years yet the diagnosis of IEI still relies on the combination of clinical acumen to identify patients at risk, leading to appropriate laboratory and genetic tests. The early evaluation of immune function provides not only critical diagnostic information, but also guides clinical decisions regarding appropriate therapies and prevention of disease-associated morbidity and mortality. As illustrated in this article and by the clinical vignette, infection may not be the significant presenting feature for IEI. Patients for whom there are clinical suspicions for IEI should be evaluated with screening tests followed by directed protein/cellular and genetic testing. As this remains an evolving field, patients may need to be re-evaluated as our understanding progresses.

Author Biographies

Christine McCusker, MD

Dr. Christine McCusker is a practicing allergist/immunologist and a clinician researcher and educator at the Children’s Hospital. She is a Clinician Scientist and Associate Professor at McGill University is Division Director for Pediatric Allergy, Immunology and Dermatology at the Montreal Children’s Hospital. Her fundamental research lab focuses on the role of early life environments in the education of the immune. She runs the pediatric transdisciplinary center for biotherapeutics, studying secondary immune deficiencies in patients receiving biologic treatments.

Sarife Saker, MD, MMSc

Dr. Sarife Saker is an allergist and immunologist in Montreal. She completed her medical degree and residency in general pediatrics at Université de Sherbrooke. She then finished her clinical immunology and allergy fellowship at McGill University. Dr. Saker has an active interest in medical education, and her clinical and research interests are focused on inborn errors of immunity, immunogenomics, food allergy and oral immunotherapy. She will pursue a postdoctoral training in immunogenomics at the Boston Children’s Hospital and an MMSc in Immunology at Harvard Medical School.
