Evaluation of neutrophil HDL-C ratio - a new inflammation marker in non-alcoholic fatty liver disease.

Introduction: Non-alcoholic fatty liver disease (NAFLD) is a global disease estimated to affect one-third of the world's population. NAFLD is the hepatic manifestation of metabolic syndrome. In recent years, formulations have been made using haematological laboratory parameters, and it has been reported to be associated with inflammation and fibrosis in the liver. In this study, we aimed to evaluate the neutrophil to high-density lipoprotein (HDL) cholesterol (HDL-C) ratio (NHR) in patients diagnosed with NAFLD by ultrasonographic imaging for the first time in the literature.

Material and methods: The study was carried out by recruiting men and women between the ages of 18 and 65 years who applied to the check-up outpatient clinic of our hospital. Ultrasonography was used as the diagnostic method for hepatosteatosis in all cases. Venous blood samples were taken from the patients for haematological and biochemical measurements.

Results: The study population consisted of 155 patients, 115 of whom were fatty liver patients and 40 were controls. NHR was determined as 99.6 ± 56.8 in those with grade 1 fatty liver, 114.98 ± 39.2 in those with grade 2, 122.9 ± 51.1 in those with grade 3, and 86.17 ± 35.2 in the control group. In the analysis, NHR was statistically significantly higher in grade 2 and 3 fatty liver patients compared with the control group (p = 0.03 and 0.01, respectively). However, there was no statistical difference between grade 1 fatty liver patients and the control group (p = 0.53).

Conclusions: We found higher NHR in patients with NAFLD. NHR is a cheap and easy to access parameter. An elevated NHR with FIB-4 in patients with NAFLD may be a marker of liver inflammation or fibrosis.
