[Anderson's disease. Apropos of a new case]

Area of Science:

• Biochemistry
• Pediatrics
• Genetics

Background:

• Anderson's disease is a rare genetic disorder affecting lipid metabolism.
• It is characterized by hypobetalipoproteinemia, leading to fat malabsorption.
• Early diagnosis is crucial for effective management and preventing complications.

Observation:

• A case of Anderson's disease in a 3-month-old infant presenting with chronic diarrhea and failure to thrive.
• Clinical signs included failure to gain weight from birth, steatorrhea, low serum cholesterol, and low plasma triglycerides.
• Intestinal biopsy confirmed the diagnosis by revealing a characteristic epithelial cell pattern.

Findings:

• The infant exhibited classic symptoms of Anderson's disease, including severe fat malabsorption.
• Biopsy findings were definitive for Anderson's disease, distinguishing it from other hypobetalipoproteinemia conditions.
• The patient's condition was managed effectively through dietary modifications.

Implications:

• Dietary management with medium-chain triglycerides can effectively treat steatorrhea in Anderson's disease.
• Distinguishing Anderson's disease from familial hypobetalipoproteinemia and abetalipoproteinemia is essential for prognosis.
• The prognosis for Anderson's disease is favorable due to the absence of neurological and ocular complications.
