Severe selenium deficiency secondary to chylous loss

Area of Science:

• Pediatric Cardiology
• Nutritional Medicine
• Rare Diseases

Background:

• Selenium deficiency is linked to poor dietary intake and can manifest in various clinical symptoms.
• Lymphangiomatosis is a rare congenital condition involving abnormal lymphatic vessel development.

Observation:

• A pediatric patient with lymphangiomatosis presented with unexplained myopathy and severe cardiomyopathy.
• The patient exhibited signs consistent with profound selenium deficiency.

Findings:

• The study identified severe selenium deficiency as the direct cause of the child's myopathy and cardiomyopathy.
• Selenium loss through chylous effusions in lymphangiomatosis was determined to be the mechanism for the deficiency.

Implications:

• This case underscores the importance of monitoring selenium levels in patients with conditions causing significant fluid loss, such as lymphangiomatosis.
• Early detection and management of selenium deficiency are crucial for preventing potentially fatal cardiac and muscular complications in affected children.
