Abstract:
Objective To investigate the changes and clinical significance of the frequency of circulating CD4+ CD25+ regulatory T cells (Treg) in nonalcoholic fatty liver (NAFL) patients.Methods CD4+ CD25+ Treg in the peripheral blood from 50 NAFL patients and 50 healthy subjects were quantitatively analyzed using flow cytometry. Group t test or Mann-Whitney U test and Spearman's rank correlation test were used for statistical analysis.Results The proportion of circulating CD4+CD25+ Treg in NAFL patients was (5.39 ± 1.94)%,which was significantly higher than that in healthy controls [(4.21±1.52)%](t=3.385,P<0.01).Further analysis revealed that the frequency of Treg was positively correlated with triglyceride (TG) level and body mass index (r=0.307 and 0.251,respectively; P=0.002 and 0.012,respectively),and negatively correlated with high density lipoproteincholesterol (HDL-C) (r=-0.306,P=0.002).Meanwhile,Treg in patients with high body mass index,high TG,low HDL-C,hypertension and metabolic syndrome (MS) were all higher than those in controls (t=2.294,2.533,3.154,2.010 and 4.454,respectively; all P<0.05).But there was no significant difference between patients with high fasting blood glucose and controls (U=1143.500,P=0.471).Conclusion The increased frequency of peripheral Treg in NAFL patients may have some relations with the imbalance of proinflammation and anti-inflammation in NAFL patients who coexisting with MS.
