Multiprofessional Critical Care Review: Pediatric 2024 (MCCRCP24ON)-Primary and Acquired Immunodeficiencies

Video Transcription

Video Summary

In this video transcript, Dr. Asya Golnik discusses primary and acquired immunodeficiencies and their relevance in the Pediatric Intensive Care Unit (PICU) setting. She explains the components of the immune system, including barriers (e.g. skin), non-cellular elements (e.g. complement), and cellular defenses (e.g. neutrophils and T/B lymphocytes). <br /><br />Dr. Golnik goes on to discuss specific disorders and defects of the immune system, such as neutropenia and neutrophil dysfunction, lymphocyte deficiencies (e.g. DiGeorge syndrome), immunoglobulin deficiencies (e.g. X-linked agammaglobulinemia), complement deficiencies, and acquired immunodeficiencies. She emphasizes the importance of recognizing the signs and symptoms of these conditions, as well as planning appropriate treatments.<br /><br />The video also covers secondary or acquired immunodeficiencies commonly seen in critical illness, including immunoparalysis, lymphopenia, and acquired hypoglobulinemias. Dr. Golnik highlights the increased risk of nosocomial infections in these patients and discusses potential treatments for immunoparalysis.<br /><br />Finally, she mentions that not all recurrent infections are immune-mediated, and that other causes such as mucous membrane or skin abnormalities, obstruction, foreign bodies, congenital issues, neurologic issues, and metabolic disorders should be considered.
