They are challenging to paediatricians as they can present anytime from birth to adolescence with a wide variety of signs and symptoms. It is important to diagnose PIDs promptly, especially more severe forms to prevent significant morbidity and mortality. However, significant challenges exist in deciding which children to investigate and when. We aim to give a basic understanding of the human immune system, the different presentations in a child that should alert a paediatrician about the possibility of PID and the possible underlying diagnosis. Additionally, we have developed a framework for a stepwise approach to investigating these children. ER -
