A noninvasive diagnostic model to assess nonalcoholic hepatic steatosis in patients with chronic hepatitis B

2017 Therapeutic Advances in Gastroenterology 10;2 (207-217)

OBJECTIVE: The objective of this study was to develop a noninvasive diagnostic test for nonalcoholic hepatic steatosis in patients with chronic hepatitis B (CHB) by using routinely available clinical markers. METHODS: A retrospective study of patients with CHB, with or without hepatic steatosis (fatty change) who were diagnosed with controlled attenuation parameter (CAP) measured by transient elastography were included. Patient information was analyzed on lifestyle; laboratory tests, including serum lipid levels; blood pressure; blood uric acid; and medical history of type 2 diabetes mellitus (T2DM). RESULTS: A total of 1312 patients were included in the study; 618 patients had confirmed hepatic steatosis. The CAP levels were significantly correlated with patient height (p -0.425, the sensitivity, specificity, positive likelihood ratio (LR) and negative LR were 74.72%, 72.12%, 2.68, and 0.35 respectively. The average FL test result was -0.54 +/- 1.26 in patients with CHB without hypertension, and 0.42 +/- 1.35, 1.12 +/- 1.65, and 1.98 +/- 1.22 in patients with hypertension grade 1, 2, and 3, respectively (p
