Aim Liver biopsy is still required for the diagnosis of hepatocellular ballooning and inflammation, which are important histological features of non‐alcoholic steatohepatitis. We undertook this multicenter, cross‐sectional study to identify novel blood markers for the diagnosis of hepatocellular ballooning. Methods We enrolled 176 patients, of whom 132 were proven by liver biopsy as having non‐alcoholic fatty liver disease (NAFLD) and classified as non‐ballooning (ballooning grade 0) ( n = 83) or ballooning (ballooning grade 1 and 2) ( n = 49) by a central pathology review. We carried out gas chromatography–mass spectrometry, hydrophilic interaction liquid chromatography tandem mass spectrometry, and lipidomics with plasma. Results As correlates of hepatocellular ballooning, among the clinical parameters, serum type IV collagen 7S correlated most significantly with the ballooning grade (correlation coefficient [CC] = 0.463; P < 0.001). Among the metabolic/lipidomic markers, phosphatidylcholine (PC) (aa‐44:8) correlated most significantly with the ballooning grade (CC = 0.394; P < 0.001). The area under the receiver operating characteristic curve of type IV collagen 7S, choline, and lysophosphatidylethanolamine (LPE) (e‐18:2), was 0.846 (95% confidence interval, 0.772–0.919). Conclusions Plasma levels of PC were positively correlated, and those of lysophosphatidylcholine and LPE were negatively correlated with hepatocellular ballooning in NAFLD patients. These non‐invasive metabolic/lipidomic‐based plasma tests might be useful to distinguish between cases of NAFLD with and without hepatocellular ballooning.
