Natural killer‐mediated antibody‐dependent cellular cytotoxicity (NK‐ADCC) responses were higher in chronic hepatitis C virus (HCV) carriers with abnormal serum alanine aminotransferase (ALT). Thirty‐one chronic HCV carriers were divided into two groups according to serum ALT level (higher or not than 40 IU/l). The percentage of CD107a, interferon (IFN)‐γ and tumour necrosis factor (TNF)‐α‐positive NK cells were compared between the ALT normal group (ALT ≤ 40 IU/l) and the abnormal group (ALT > 40 IU/l). Statistical analyses were performed by non‐parametric t test. All P‐values were two‐tailed and considered significant when lower than 0·05. [Colour figure can be viewed at wileyonlinelibrary.com].
