Severe-Enduring Anorexia Nervosa (SE-AN): a case series

Area of Science:

• Psychiatry
• Clinical Psychology
• Internal Medicine

Background:

• Anorexia Nervosa (AN) presents therapeutic challenges, particularly Severe and Enduring Anorexia Nervosa (SE-AN).
• SE-AN is linked to severe medical issues, high service utilization, and elevated mortality rates.
• This subset requires specialized attention due to its complex nature and poor prognosis.

Purpose of the Study:

• To examine the characteristics of patients with Severe and Enduring Anorexia Nervosa (SE-AN).
• To investigate treatment compliance and contributing factors in SE-AN.
• To understand variables influencing the complexity and chronicity of SE-AN.

Main Methods:

• A case series design was employed.
• 14 patients with SE-AN were selected from an outpatient eating disorder unit.
• Data collected focused on disease effects, treatment adherence, and complexity-related variables.

Main Results:

• The study identified significant treatment resistance in SE-AN patients.
• Medical and psychological complications are prominent throughout the SE-AN patient's life.
• Chronicity is influenced by the ego-syntonic nature of the disorder and systemic factors.

Conclusions:

• Treatment resistance is a key issue in SE-AN.
• Medical and psychological complications significantly impact SE-AN patients.
• Factors contributing to chronicity include ego-syntonicity, delayed diagnosis, and social/occupational impairment.
