Dear Colleagues,

Primary immunodeficiency disorders (PIDs) are a realm where the intricacies of the immune system and the challenges faced by individuals with compromised immunity converge. This book comprehensively explores these disorders’ complexities, focusing specifically on their manifestations and management in the adult population.

PIDs are a group of rare, often genetic, conditions that leave individuals susceptible to recurrent and severe infections. While the field has made remarkable strides in understanding the genetic and molecular basis of these disorders, there is a growing need for a consolidated resource tailored to the unique considerations of adults affected by these conditions.

In this book, we bring together a group of experts to provide a holistic overview of PIDs in adults. This book of chapters in delve into the genetic underpinnings, clinical presentations, diagnostic approaches, and therapeutic interventions that characterize these disorders in the adult context.

We embark on this journey with the understanding that primary immunodeficiency disorders can significantly impact the quality of life for affected individuals. We aim to equip healthcare professionals, researchers, and students with a nuanced understanding of these disorders, fostering improved diagnosis, management, and ultimately, the well-being of those living with primary immunodeficiencies.

The content within these book is organized to serve as a valuable resource for healthcare practitioners seeking to enhance their knowledge and skills in managing adult patients with PIDs. Additionally, we hope this book will stimulate further research, collaboration, and innovation in the field, ultimately advancing our ability to provide effective and personalized care.

I would like to express my gratitude to the contributing authors for their expertise and dedication to advancing the understanding of PIDs. I also extend my appreciation to the readers for their interest in this critical area of medicine.

May this book serve as a guide, a reference, and an inspiration for all those committed to improving the lives of adults facing the challenges of PIDs.
