Alterations in endothelium-associated proteins and serum thyroid hormone concentrations in anorexia nervosa.

Plasma concentrations of endothelium-associated proteins ( EAP) (plasma fibronectin (PFN), angiotensin-converting enzyme, factor VIII-related antigen (F VIII-R:Ag)) and tissue plasminogen activator and serum thyroid hormone concentrations were studied in nine patients with anorexia nervosa (AN), before and after weight gain. Before weight gain (-35.9 (SE 2.3)% of standard body-weight) PFN was significantly reduced and F VIII-R:Ag was significantly increased in AN patients compared with the concentrations in control subjects (211.5 (SE 14.9) v. 274.7 (SE 16.6) micrograms/ml, P < 0.05; 129.2 (SE 14.1) v. 88.2 (SE 9.7) %, P < 0.05 respectively). Serum triiodothyronine (T3) and free T3 levels were also significantly lower before weight gain in AN patients (0.85 (SE 0.07) v. 1.53 (SE 0.08) nmol/l, P < 0.001; 2.57 (SE 0.23) v. 5.31 (SE 0.34) pmol/l, P < 0.001 respectively), although serum thyroxine (T4), free T4, and thyrotropin concentrations were within the normal range throughout the study periods. Following weight gain, PFN and F VIII-R:Ag concentrations normalized as did the thyroid hormone levels. The incremental changes in PFN levels correlated significantly with those in serum thyroid hormone concentrations (T3, r 0.79, P < 0.01; free T3, r 0.84, P < 0.01). These findings suggest that PFN levels may be directly related to serum T3 concentrations in AN patients.[1]
