Iron overload may be critical for liver dysfunction in anorexia nervosa, and the role of haematocrit-adjusted albumin in assessing nutritional status: a case report

Abstract Background Anorexia nervosa (AN) is frequently associated with liver dysfunction, but the precise mechanism remains undefined. Since the nutritional marker albumin has a low correlation with changes in body weight in AN, and patients with AN often have dehydration as a complication, we also...

description Abstract Background Anorexia nervosa (AN) is frequently associated with liver dysfunction, but the precise mechanism remains undefined. Since the nutritional marker albumin has a low correlation with changes in body weight in AN, and patients with AN often have dehydration as a complication, we also examined whether haematocrit (HCT)-adjusted serum albumin could be a better nutritional marker in AN. Case presentation We describe a 15-year-old girl with severe weight loss and liver damage whose liver enzymes normalized after 1.5 months of hospitalization and weight gain. We found a significant correlation between body weight (BW) and HCT-adjusted serum albumin (Spearman’s rank correlation coefficient (rs) = 0.66, P = 5.28 × 10−3) and between BW and alanine aminotransferase (ALT) (rs = -0.825, P = 8.45 × 10−5). After division by HCT, correlations between serum albumin and ALT (rs = -0.835, P = 5.24 × 10−5) and between the iron-storage protein ferritin and the liver enzyme gamma-glutamyl transferase (rs = 1.0, P = 0.017) were also statistically significant. Conclusion These results suggest that improvement of the nutritional status in AN could relieve liver dysfunction and facilitate iron transport. Since a decrease in the iron-transport protein transferrin presumably increases labile non-transferrin-bound iron, resulting in excess reactive oxygen species production, a defect in iron transport due to malnutrition could be one of the causes of liver injury in AN. In addition, HCT-adjusted albumin could be a better marker than its raw data to assess changes in nutritional status in AN.
