The 2025 practice parameter for inborn errors of immunity updates diagnosis and management guidelines. Key changes include newborn screening, genetic testing, and updated recommendations for treatment strategies like immunoglobulin replacement and transplantation.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- The practice parameter for inborn errors of immunity (IEI) guides clinical care.
- Previous revisions focused on specific genetic disorders.
- The 2015 parameter update established a baseline for current practices.
Purpose of the Study:
- To review significant changes in the 2025 practice parameter for IEI.
- To compare the updated parameter with the 2015 version.
- To highlight the new structure and key recommendations for diagnosis and management.
Main Methods:
- Review of the recently published 2025 practice parameter for IEI.
- Comparative analysis against the 2015 parameter update.
- Identification and summarization of structural and content modifications.
Main Results:
- The 2025 parameter features a new two-part structure: diagnosis and management.
- Diagnostic recommendations now encompass newborn screening for severe combined immunodeficiency (SCID), genetic testing, comorbidity surveillance, and immunological testing.
- Management recommendations cover immunoglobulin replacement, antibiotic prophylaxis, hematopoietic stem cell transplantation, precision medicine, and quality of life.
Conclusions:
- The 2025 practice parameter represents a significant structural and content update for IEI care.
- The revised parameter offers a comprehensive, integrated approach to diagnosing and managing IEI.
- This update emphasizes advancements in screening, diagnostics, and therapeutic strategies, including precision medicine.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
