Overview
Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency characterized by eczema, thrombocytopenia, recurrent infections, and increased susceptibility to malignancies 14.Diagnosis
Clinical Features: Recurrent infections, eczema, and thrombocytopenia 14.
Laboratory Findings: Abnormalities in T-cell function, reduced antibody responses, and low platelet count 14.
Molecular Testing: Confirmation through molecular screening of WAS gene mutations 3.Management
First-Line Treatment: Immunoglobulin replacement therapy to manage infections and immune dysfunction 14.
Adjunctive Treatments:
- Platelet Transfusion: For severe thrombocytopenia 1.
- Allogeneic Hematopoietic Stem Cell Transplantation (HSCT): Curative option for severe cases 2.Special Populations
Pediatrics: Early HSCT (median age 30 months) improves outcomes 2.
Comorbidities: Severe refractory thrombocytopenia (SRT) early in life is a significant risk factor for poor prognosis 1.Key Recommendations
Early HSCT for Severe Cases: Consider allogeneic HSCT in severe WAS cases to achieve curative outcomes (Evidence: Moderate) 2.
Monitor Platelet Count Closely: Regular monitoring of platelet counts is crucial as severe thrombocytopenia predicts poor prognosis (Evidence: Strong) 1.
Initiate Immunoglobulin Therapy: Start immunoglobulin replacement therapy to manage recurrent infections and immune deficiencies (Evidence: Expert opinion) 14.References
