Use of GP73 in the diagnosis of non-alcoholic steatohepatitis and the staging of hepatic fibrosis

Objective

To evaluate the utility of Golgi protein 73 (GP73) in the diagnosis of non-alcoholic steatohepatitis (NASH) and hepatic fibrosis (HF) staging.

Methods

Ninety-one patients with non-alcoholic fatty liver disease (NAFLD) were allocated to NAFL (n = 46) and NASH (n = 45) groups according to their NAFLD activity score (NAS), and there were 30 healthy controls. Serum GP73 was measured by ELISA, GP73 protein expression was evaluated using immunohistochemistry, and FibroScan was used to determine liver hardness.

Results

The serum GP73 concentrations of the NAFL and NASH groups were significantly higher than those of controls. GP73 expression in the liver of the patients gradually progressed from absent or low to moderate or high. Serum GP73 positively correlated with liver expression, and the serum and liver GP73 of the patients positively correlated with FibroScan value and HF stage. There was a strong positive correlation of the combination of alanine aminotransferase, gamma glutamyl transferase and GP73 with NASH. The combination of serum GP73 and FibroScan value was found to predict NASH (NAS > 4) and advanced HF (stage ≥2) in patients with NAFLD using receiver operating characteristic analysis.

Conclusion

Serum GP73 may be useful in the diagnosis of NASH and the staging of HF.

Sex hormones abnormalities in non-alcoholic fatty liver disease: pathophysiological and clinical implications

Obesity and metabolic syndrome are conditions at high risk for the development of complications such as type 2 diabetes mellitus, atherosclerotic cardiovascular disease, and non-alcoholic fatty liver disease (NAFLD). The growing prevalence of NAFLD has recently raised attention in the clinical practice, due to the worsening prognosis observed in the affected patients. Sex hormones abnormalities, commonly found in subjects suffering from obesity and metabolic syndrome, have been recently hypothesized to be directly involved in the physiopathology of obesity-related comorbidites; however, their role in the pathogenesis of NAFLD remains unclear. In this review of the available literature, a summary of the knowledge about the role of sex steroids abnormalities in the risk of developing NAFLD was performed, mentioning the possible clinical implications for therapy.

Looking for a new name for non-alcoholic fatty liver disease in Spanish: esteatosis hepática metabólica (EHmet)

The name of a disease does not follow any defined protocol and the scientific community's acceptance of several variants based on the customs of every location is usual. There are examples of prevalent entities with curious naming processes, such as diabetes mellitus. The first word, "diabetes", comes from the Greek dia (through), be (to go), and tes (factor), while the second word, "mellitus", comes from Latin melli (honey). As a consequence, diabetes mellitus literally means "the sweet factor that goes through…", pertaining to an excessive and sweet diuresis. Thus, we could deduce that a definition representing exactly the pathophysiology of the particular disease is not required.
