Bottom Line: Partial realimentation significantly reduced serum MIC-1 concentrations in patients with AN but it still remained significantly higher compared to control group.MIC-1 concentrations in AN patients are significantly higher relative to healthy women.Partial realimentation significantly decreased MIC-1 concentration in AN group.

ABSTRACT

Background: Macrophage inhibitory cytokine-1 (MIC-1) is a key inducer of cancer-related anorexia and weight loss. However, its possible role in the etiopathogenesis of nutritional disorders of other etiology such as anorexia nervosa (AN) is currently unknown.

Methods: We measured fasting serum concentrations of MIC-1 in patients with AN before and after 2-month nutritional treatment and explored its relationship with nutritional status, metabolic and biochemical parameters. Sixteen previously untreated women with AN and twenty-five normal-weight age-matched control women participated in the study. We measured serum concentrations of MIC-1 and leptin by ELISA, free fatty acids by enzymatic colorimetric assay, and biochemical parameters by standard laboratory methods; determined resting energy expenditure by indirect calorimetry; and assessed bone mineral density and body fat content by dual-energy X-ray absorptiometry. ANOVA, unpaired t-test or Mann-Whitney test were used for groups comparison as appropriate. The comparisons of serum MIC-1 levels and other studied parameters in patients with AN before and after partial realimentation were assessed by paired t-test or Wilcoxon Signed Rank Test as appropriate.

Results: At baseline, fasting serum MIC-1 concentrations were significantly higher in patients with AN relative to controls. Partial realimentation significantly reduced serum MIC-1 concentrations in patients with AN but it still remained significantly higher compared to control group. In AN group, serum MIC-1 was inversely related to Buzby nutritional risk index, serum insulin-like growth factor-1, serum glucose, serum total protein, serum albumin, and lumbar bone mineral density and it significantly positively correlated with the duration of AN and age.

Conclusions: MIC-1 concentrations in AN patients are significantly higher relative to healthy women. Partial realimentation significantly decreased MIC-1 concentration in AN group. Clinical significance of these findings needs to be further clarified.

Serum concentrations of macrophage inhibitory cytokine-1 in anorexia nervosa. Serum concentrations of macrophage inhibitory cytokine-1 (MIC-1; pg/ml) in normal-weight healthy control women (C; n = 25), patients with anorexia nervosa before the beginning of any treatment (AN pre-treatment; n = 16) and patients with anorexia nervosa after two months of refeeding (AN post-treatment; n = 16). *p < 0.05 vs. controls (Mann-Whitney test), +p < 0.05 vs. pre-treatment values (Wilcoxon Signed Rank Test).

Mentions: At baseline, fasting serum MIC-1 concentrations were significantly higher in patients with AN relative to control group of healthy normal-weight women (Figure 1). Partial realimentation significantly reduced serum MIC-1 concentrations in patients with AN but it still remained significantly higher compared to controls (Figure 1).
