| Summary | Objective The rate of platelet count reduction appears to differ among different liver diseases. In the present study, we investigated the difference in the platelet counts of patients with nonalcoholic fatty liver disease (NAFLD) and those with chronic liver disease due to hepatitis C virus (CLD-HCV). Methods The study population included 620 patients with NAFLD and 405 patients with CLD-HCV, all of whom were diagnosed by liver biopsy. The relationships between the grade of fibrosis and the platelet count in the two diseases were compared. The optimal cut-off value for the diagnosis of liver cirrhosis (LC) was measured. The relationships between the platelet count and anti-platelet antibodies, the serum thrombopoietin level, the grade of splenomegaly and liver stiffness were also investigated in both LC groups. Results In NAFLD patients, the platelet count was significantly higher at each grade of fibrosis in comparison to CLD-HCV. The optimal cut-off value for the diagnosis of LC was 16.0×104/μL [sensitivity, 86.7%; specificity, 87.6%; area under the curve (AUC), 0.930] in NAFLD and 12.7×104/μL (sensitivity, 57.8%; specificity, 88.2%; AUC, 0.863) in CLD-HCV. No anti-platelet antibodies were detected in patients with either type of LC. The serum thrombopoietin levels, the distribution of splenomegaly grades, and liver stiffness did not differ between the two LC groups to a statistically significant extent. As the splenomegaly grade increased, the platelet count decreased. Conclusion The optimal cut-off values for diagnosing LC differed between the two diseases and should be determined separately. The reason for the difference in platelet reduction is still unclear, and requires further investigation. |
