Task: Question Generation
Input (English): Circulating adrenomedullin (ADM), a potent vasorelaxing and natriuretic peptide involved in cardiovascular homeostasis, is increased after cardiac and renal transplantation. ADM is also implicated in hemodynamic abnormalities during liver cirrhosis, but whether ADM is increased late after liver transplantation is unknown.', 'A total of 18 subjects--10 liver-transplant patients (Ltx) and 8 healthy subjects--were enrolled in the study.', 'After a 15-min rest period in supine position, heart rate and systemic blood pressure were determined in all subjects. Then, venous blood samples were obtained in order to simultaneously determine the cyclosporine through levels, the biological (cyclosporine, renal and hepatic functions) and hormonal (ADM and atrial natriuretic peptide (ANP)) characteristics of the Ltx.', 'ADM (27.2+/-4.1 vs. 53.8+/-6.9 pmol/l, P=0.02), and ANP (5.9+/-0.9 vs. 12.8+/-1.4 pmol/l, P=0.001) were significantly increased in late, stable Ltx (35.4+/-9.6 months after transplantation). Furthermore, increased ADM correlated positively with elevated creatinine (r=0.76, P=0.01) and ANP (r=0.64, P=0.04) after liver transplantation.
Output (English): Is circulating adrenomedullin increased in relation with increased creatinine and atrial natriuretic peptide in liver-transplant recipients?
