Resumen

Background: Osteocalcin is a hormone with a complex cross-talk between adipose tissue and the skeleton. The aim of the present study was to explore the relation of osteocalcin with histopathological changes of NALFD patients. Subjects: A population of 69 NAFLD patients was analyzed. A liver biopsy was realized. Weight, fat mass, body mass index, basal glucose, insulin, insulin resistance (HOMA), total cholesterol, LDLcholesterol, HDL-cholesterol, triglycerides and osteocalcin levels were measured. Results: Patients were divided in two groups by median osteocalcin value (11.34 ng/mL), group I (patients with the low values) and group II (patients with the high values). Only liver fibrosis frequencies were different between groups (group I: 22.9% vs group II: 9.4%; p < 0.05). Patients in group I had higher levels of glucose (115.6 ± 28.1 mg/dL vs. 103.7 ± 24.3 mg/dL; p < 0.04), HOMA (4.6 ± 3.1 units vs. 3.6 ± 1.8 units; p < 0.04), weight (102.9 ± 32.4 kg vs. 85.9 ± 16.8 kg; p = 0.002) and body mass index (38.3 ± 11.4 kg/m2 vs. 30.1 ± 5.7 kg/m²; p = 0.001)) than patients in group II. Osteocalcin was inverse correlated with glucose (r =-0.4; p = 0.002) and HOMA (r = -0.3: p = 0.01). Conclusion: Osteocalcin is associated with liver fibrosis. However, this association disappeared in a multivariate analysis, and HOMA remained as an independent factor.
