Home Parenteral Nutrition Therapy in Seven Patients with Anorexia Nervosa: The Role and Indications

: Home parenteral nutrition (HPN) is a well-established intervention to sustain life in malnourished patients at home. Because it is difficult for patients with anorexia nervosa (AN) to gain weight or stop purging, such patients require repeated hospitalizations. Although HPN has not been commonly used for AN patients in Japan, we utilized this approach to treat seven AN patients. We herein present the clinical course and outcome of these seven patients, the application criteria for HPN in our institution, and the potential problems associated with HPN. Despite its complications, HPN may be a useful measure to help patients with persistent AN avoid multiple hospitalizations.
