The frequency of peripheralNKT cells was detected by flow cytometry. Clinical andlaboratory data were collected for further analysis. RESULTS: NAFLD patients had a lower frequencyof peripheral NKT cells than healthy controls (1.21%± 0.06% vs 1.62% ± 0.07%, P < 0.001). Furtheranalysis revealed that the frequency of peripheralNKT cells was negatively correlated with body massindex, waist circumference and serum levels of alanineaminotransferase. Logistic regression analysis revealedthat elevated body mass index [hazard ratio (HR):2.991], aspartate aminotransferase levels (HR: 1.148)and fasting blood sugar (HR: 3.133) increased the riskof NAFLD, whereas an elevated frequency of peripheralNKT cells (HR: 0.107) decreased the risk. CONCLUSION: Changes in the frequency of peripheralNKT cells were correlated with NAFLD and a decreasedfrequency of peripheral NKT cells was a risk factor forNAFLD.展开更多
