Abstract:

Objective To systematically evaluate the correlation between pathological changes and serum ferritin and iron levels in nonalcoholic fatty liver disease (NAFLD). Methods Chinese and English literatures form PubMed, China National Knowledge Internet (CNKI), VIP, Wanfang Data, Cochrane Library, published up to December 2021, regarding the correlation between pathological changes and serum ferritin and iron levels in NAFLD, were enrolled. Secondary screening, quality assessment and data extraction were performed, and then Stata12.0 software was used for meta-analysis. Results Thirty-two articles were included, representing 4 177 patients. Meta-analysis showed that the serum ferritin ( S M D=0.93, 95% C l: 0.85-1.01, P=0.000) and serum iron levels ( S M D=0.57, 95% C l: 0.37-0.76, P=0.000) in NAFLD group were higher than those in the control group. Compared with patients with simple fatty liver, the serum ferritin ( S M D=0.59, 95% C l: 0.41-0.78, P=0.000) in patients with nonalcoholic steatohepatitis was increased, and but no statistically significant difference in serum iron ( S M D=0.14, 95% C l: 0.00-0.29, P=0.057). Conclusion The presence of NAFLD correlates with increased serum ferritin and iron levels, and the pathological changes of NAFLD correlates positively with serum ferritin and iron levels. The causal relationship of the threes in NAFLD and the pathogenesis of NAFLD should be further investigation and verification in clinical.
