Primary Immunodeficiency Diseases
Primary immunodeficiency diseases (PIDs) are a heterogeneous group of monogenic disorders in which part of the immune system is deficient or does not function properly. Patients with PID commonly present with recurrent infections, which explains the importance of the immune system in protection from organisms. PIDs are classified according to the affected component of the immune system into innate immunity disorders and adaptive immunity disorders. Early diagnosis and aggressive management ranging from medical treatment to stem cell transplantation are crucial to decrease disease-associated morbidity and mortality. In this review, we will provide a detailed overview of classification, diagnosis, and treatments of PIDs, with particular attention to the critical care management of the common complications of these rare diseases.
