Anorexia nervosa with severe liver dysfunction and subsequent critical complications
Internal Medicine (Tokyo, Japan)
|August 6, 1999
Summary
Severe malnutrition in anorexia nervosa can cause critical liver and pancreatic dysfunction. Aggressive treatment, including plasmapheresis and hemodialysis, is vital for survival in these complex cases.
Area of Science:
- Internal Medicine
- Gastroenterology
- Endocrinology
Background:
- Anorexia nervosa is a severe eating disorder characterized by self-starvation and significant weight loss.
- Malnutrition associated with anorexia nervosa can lead to multi-organ dysfunction.
Observation:
- A 20-year-old female with anorexia nervosa (BMI 11) presented with severe liver dysfunction (AST 5000 IU/l, ALT 3980 IU/l), hypoglycemia (27 mg/dl), and pancreatic dysfunction (amylase 820 IU/l, lipase 558 IU/l).
- The patient experienced a depressive state and irritability, unresponsive to intravenous glucose.
- Despite plasmapheresis, she developed pulmonary edema, acute renal failure, gastrointestinal bleeding, and disseminated intravascular coagulation.
Findings:
- The patient's critical condition improved with hemodialysis, mechanical ventilation, and pharmacotherapy including prednisolone, prostaglandin E1, and branched-chain amino acids.
- Malnutrition is hypothesized as the primary cause of liver dysfunction and subsequent life-threatening complications.
Implications:
- This case highlights the potential for severe, multi-systemic complications arising from anorexia nervosa-related malnutrition.
- Early recognition and aggressive, multi-modal treatment are crucial for managing critical illness in patients with severe anorexia nervosa.
- Further research into the specific mechanisms linking malnutrition to organ dysfunction in anorexia nervosa is warranted.
