Chédiak-Higashi syndrome

Last edited: 4/22/2026

Overview

Chédiak-Higashi syndrome (CHS) is a rare, autosomal recessive disorder characterized by partial albinism, recurrent infections, and progressive neurological decline due to abnormal lysosomal function and large granule lymphocyte inclusions 1.

Diagnosis

  • Key Diagnostic Criteria:
    • - Partial albinism - Recurrent bacterial and fungal infections - Giant granules in leukocytes - Neurological abnormalities
  • Recommended Tests:
    • - Lysosomal enzyme activity assays in granulocytes and lymphocytes (e.g., alpha-mannosidase, alpha-galactosidase, alpha-fucosidase, beta-glucuronidase) 1 - Genetic testing for CHS-related mutations (not detailed in abstracts)

    Management

  • First-Line Treatments:
    • - Prophylactic antibiotics to prevent recurrent infections 1 - Immunoglobulin replacement therapy for immunodeficiency 1
  • Adjunctive Treatments:
    • - Antimicrobial prophylaxis tailored to common pathogens 1 - Supportive care for neurological symptoms (specific interventions not detailed in abstracts)

    Special Populations

  • Pediatrics: Early intervention with prophylactic antibiotics and immunoglobulin therapy is crucial 1
  • Comorbidities: Management of recurrent infections and neurological decline requires multidisciplinary care 1

    • Key Recommendations

  • Perform lysosomal enzyme activity assays in granulocytes and lymphocytes for definitive diagnosis of Chédiak-Higashi syndrome (Evidence: Moderate) 1
  • Initiate prophylactic antibiotics and immunoglobulin replacement therapy to manage recurrent infections and immunodeficiency (Evidence: Moderate) 1
  • Tailor antimicrobial prophylaxis based on common pathogens encountered in affected individuals (Evidence: Expert opinion) 1
