title: Plasma des-acyl and acyl ghrelin in patients with eating disorders.
abstract: A recently recognized peptide, ghrelin, increases appetite and energy retention in human. Previous reports have shown higher plasma level in eating disorder (ED) patients and correlations with body mass index (BMI). This study examined these findings by measuring active (N-RIA) and total (C-RIA) levels of plasma ghrelin. Multipurpose assessments of symptoms were conducted for 11 ED patients and 5 control females. Results revealed significant differences of C-RIA between the groups. The BMI did not correlate with ghrelin, but demonstrated reversal correlation with the ratio of N-RIA and C-RIA (NC ratio) according to the ED or control group. The NC ratio also tended to be associated with a self-rating score. The NC ratio might be related to specific characteristics of ghrelin secretion or clearance in ED patients. Further basic and clinical investigations are necessary.
