Abstract

Patients with hypopituitarism have the feature of metabolic syndrome, including central obesity, insulin resistance, and dyslipidemia. Because metabolic syndrome, including insulin resistance, is the main pathogenesis of the development of nonalcoholic fatty liver disease (NAFLD), we considered that patients diagnosed with hypopituitarism have an increased risk of developing NAFLD. We compared control subjects and hypopituitary men in metabolic parameters and the frequency of fatty liver on abdominal ultrasonography, and analyzed associating factors with the severity of the fatty liver in patients with hypopituitarism. 34 male patients with hypopituitarism and 40 age and sex-matched control subjects were included. The frequency of fatty liver on abdominal ultrasonography was significantly higher in hypopituitary men compared to control subjects (32.5% vs. 70.6%, p=0.001). Ln CRP and free fatty acids were significantly elevated in hypopituitary patients with fatty liver compared to patients without fatty liver. Ln GH was significantly lower in hypopituitary patients with fatty liver. The severity of fatty liver on abdominal ultrasonography correlated with negatively Ln GH, after adjusting for the BMI effect (p=0.020). There is a difference only between the severe fatty liver group and normal liver group in the analysis of the mean Ln GH level between 4 groups according to the severity of fatty liver (p=0.036). In conclusion, NAFLD is more common in hypopituitary patients than control subject. Severe growth hormone deficiency in hypopituitarism was associated with the severe degree of hepatic steatosis in NAFLD.
