[Studying the correlation between ferritin and non-alcoholic fatty liver disease]

Abstract

Objective: To analyze the correlation between serum ferritin and steatosis in non-alcoholic fatty liver disease. Methods: Data of 167 cases who underwent liver biopsy in the Affiliated Hospital of Hangzhou Normal University were collected. Hydrogen proton magnetic resonance spectroscopy were performed within one week. The pathological results of liver biopsy were used as the gold standard to analyze the case data, serological indicators, magnetic resonance spectroscopy-proton density fat fraction. Results: Pathological monitoring result showed that the serum ferritin in patients without steatosis, and with mild, moderate and severe steatosis were (206.20 ± 189.83), (286.65 ± 200.80), (326.55 ± 214.71), (391.50 ± 184.93) ng/ml, respectively, P < 0.005. Serum ferritin was correlated to body mass index, PDFF, alanine aminotransferase, gamma glutamyltransferase, low-density lipoprotein, high-density lipoprotein. The area under ​​the receiver operating characteristic curve with ferritin for the diagnosis of non-alcoholic fatty liver disease was 0.716, and the optimal diagnostic threshold was 214.56 ng/ml. The sensitivity and specificity were 80.1%, and 68.8%, respectively. There was no statistically significant difference between the intralobular inflammation, fibrosis, and ferritin. Prussian blue iron staining had no apparent deposition of iron particles. Conclusion: Ferritin has significant positive correlation with the results of pathological and magnetic resonance imaging for liver steatosis. Therefore, it can be used as a non-invasive diagnostic method for liver steatosis evaluation.
