Summary
Wiskott-Aldrich syndrome (WAS) patients frequently develop autoimmune conditions, impacting prognosis and indicating a need for stem-cell transplantation. This review details autoimmune issues in WAS, their mechanisms, and genetic links.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- Wiskott-Aldrich syndrome (WAS) is a rare X-linked immunodeficiency.
- It presents with thrombocytopenia, eczema, and recurrent infections.
- WAS patients have increased risks of autoimmunity and cancers.
Purpose of the Study:
- To review autoimmune manifestations in Wiskott-Aldrich syndrome.
- To summarize proposed immunopathogenic mechanisms.
- To discuss genetic variants linked to autoimmunity in WAS.
Main Methods:
- Narrative review of published data.
- Collated existing research on autoimmune manifestations in WAS.
- Included information on immunopathogenesis and genetics.
Main Results:
- Autoimmunity affects 26%-72% of WAS patients.
- Autoimmunity is a poor prognostic factor and linked to malignancy.
- Autoimmunity development suggests the need for hematopoietic stem-cell transplantation.
Conclusions:
- Autoimmune manifestations are a significant clinical feature of WAS.
- Understanding these mechanisms and genetic factors is crucial for patient management.
- Early identification of autoimmunity aids in treatment decisions, including transplantation.

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
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,...
