How does Wiskott-Aldrich syndrome affect the immune system?

Changes in white blood cells lead to an increased risk of several immune and inflammatory disorders in people with Wiskott-Aldrich syndrome. These immune problems vary in severity and include an increased susceptibility to infection from bacteria, viruses, and fungi.

How do you treat Wiskott-Aldrich syndrome?

Stem cell/bone marrow transplants A stem cell transplant (also known as a bone marrow transplant) is the mainstay of treatment for Wiskott-Aldrich syndrome. This is the only available treatment option that has a chance of providing a permanent cure. Stem cells are a versatile type of cell found in bone marrow.

How is Wiskott-Aldrich syndrome inherited?

Wiskott-Aldrich syndrome follows an X-linked inheritance pattern. Each person has 23 pairs of chro- mosomes—one pair of sex chromosomes (XX for girls and XY for boys) and 22 pairs of numbered chromosomes, called autosomes. WAS is located on the X chromosome.

What defect causes Wiskott-Aldrich syndrome?

Sometimes a boy can be born with the faulty X chromosome, even though his mother is not a carrier of the mutation (in this case, the mutation arises in the germ cell of the mother). Wiskott-Aldrich syndrome develops as the result of a defect in a gene located on the X chromosome.

Why are there small platelets in Wiskott-Aldrich syndrome?

The presence of small platelets with mean platelet value (MPV) less than 6 fL characterizes Wiskott-Aldrich syndrome (WAS), whereas the other 2 disorders usually have large MPVs because of the young age of the platelets.

Does Wiskott-Aldrich syndrome affect B cells?

Wiskott-Aldrich syndrome (WAS) is an X-linked immunodeficiency disorder characterized by recurrent infections, microthrombocytopenia, and eczema. In addition, WAS is associated with an increased incidence of autoimmune disease and hematologic malignancies, especially B-cell lymphomas.

Why is IgM low in Wiskott Aldrich?

We have investigated IgM deficiency in Wiskott-Aldrich syndrome patients. From the assessment of T and B cell functions in pokeweed mitogen-induced immunoglobulin (Ig) production, IgM deficiency was chiefly thought to result from B cell dysfunction.

What is the diagnosis of Wiskott-Aldrich syndrome?

Wiskott-Aldrich syndrome (WAS) is an X-linked disorder characterized by the clinical triad of microthrombocytopenia, eczema, and recurrent infections.

How is Wiskott-Aldrich syndrome related to neutropenia?

It is also sometimes called the eczema-thrombocytopenia-immunodeficiency syndrome in keeping with Aldrich’s original description in 1954. The WAS-related disorders of X-linked thrombocytopenia (XLT) and X-linked congenital neutropenia (XLN) may present similar but less severe symptoms and are caused by mutations of the same gene.

What is the role of wasp in Wiskott Aldrich syndrome?

The Wiskott-Aldrich syndrome protein (WASP): roles in signaling and cytoskeletal organization. Annu Rev Immunol. 1999. 17:905-29. [Medline]. Kwan SP, Hagemann TL, Radtke BE, et al. Identification of mutations in the Wiskott-Aldrich syndrome gene and characterization of a polymorphic dinucleotide repeat at DXS6940, adjacent to the disease gene.

What kind of thrombopoietic agent does Wiskott Aldrich use?

Study of eltrombopag, a thrombopoietic agent used to increase platelets in ImmuneThrombocytopenic Purpura (ITP), in WAS concluded that although it increased platelet numbers it failed to increase platelet activation in most patients.
