    Anorexia nervosa patients with significant weight loss showed impaired cellular immunity (anergy). Nutritional status, particularly weight loss and skinfold thickness, strongly predicted anergy, not just protein levels.

    Area of Science:

    • Immunology
    • Nutritional Science
    • Clinical Medicine

    Background:

    • Anorexia nervosa is associated with various medical complications.
    • Cellular immune dysfunction is frequently observed in malnourished individuals.

    Purpose of the Study:

    • To investigate cellular immune functioning in patients with anorexia nervosa.
    • To determine the relationship between nutritional status and cellular immunity.

    Main Methods:

    • Evaluated 22 anorexia nervosa patients using an anergy panel (candida, streptokinase-streptodornase, mumps antigen).
    • Assessed nutritional status via weight, protein levels, iron-binding capacity, and anthropometric measurements.

    Main Results:

    • Six of 22 patients exhibited anergy (impaired delayed hypersensitivity).

  • Anergy correlated significantly with weight loss severity and triceps skinfold thickness.
  • Visceral protein measures (albumin, transferrin) did not correlate with anergy.

    • Conclusions:

    • Cellular immunity in anorexia nervosa is compromised by advanced weight loss.
    • Anthropometric indices of malnutrition are stronger predictors of anergy than visceral protein levels.
