16. Non-alcoholic fatty liver disease and thrombocytopenia IV: its association with granulocytopenia
ABSTRACT Introduction: We have previously shown that some patients present thrombocytopenia (less than 100 × 109/L platelets) in non-alcoholic fatty liver disease (NAFLD). To further explore the nature of this association, we have now analyzed the association of thrombocytopenia with neutropenia (less than 0.5 × 109/L granulocytes) in NAFLD. Material and
