TNK% was detected using flow cytometry. Serum IL4 and IFN-γ were measured by ELISA. Diabetes biochemical parameters were also analyzed.Results: Significant decrease was detected in TNK% and IFN-γ in DFI group compared to other 2 groups (P< 0.001). Significant decrease was detected in serum levels of IL4 in DFI group compared to T2DM group (P=0.006). IFN-γ/IL4 was significantly decreased in DFI compared to DFU group (P=0.020). There was a significant correlation of TNK% with both IL4 and IFN-γ (r=0.385, P< 0.001; r=0.534, P< 0.001, respectively). Significant negative correlation of TNK% with HbA1c and LDL was revealed (r=− 0.631, P< 0.001; and r=− 0.261, P=0.013, respectively), while a positive correlation was seen with HDL (r=0.287, P=0.006). A significant negative correlation of IL4 with HbA1c was found (r=− 0.514, P< 0.001;. As for IFN-γ, a significant negative correlation with HbA1c and LDL was detected (r=− 0.369, P< 0.001; r=− 0.229, P=0.030). TNK % and IFN-γ level showed negative correlations with disease duration/year (r=− 0.546, P< 0.001; r=− 0.338, P=0.001,respectively).Conclusion: Decline in TNK frequency has essential role in T2DM pathogenesis and subsequent foot complications. Downregulation of TNK% and IFN-γ level have potential roles in predicting infection of diabetic ulcer and are correlated with disease duration.Keywords: diabetic foot ulcer, diabetic foot infection, natural killer cell, interferon gamma, interleukin 4 |
