The differences in selected parameters of innate immunity between the study groups.
| Evaluated parameters | Patients with DFUs (n = 68) | Diabetic controls (n = 34) | p value |
|---|---|---|---|
| C3 (g/L) | 1.32 ± 0.27 | 1.35 ± 0.19 | NS |
| C4 (g/L) | 0.3 ± 0.08 | 0.28 ± 0.07 | NS |
| Percentage of phagocyting PMN cells (%) | 98.2 ± 1.7 | 97.9 ± 1.4 | NS |
| FAGSI | 67.6 ± 27.7 | 65.8 ± 30.1 | NS |
| Percentage of NK cells (%) | 13.45 ± 6.46 | 13.15 ± 5.83 | NS |
| Absolute numbers of NK cells (cells/μL) | 226 ± 113 | 327 ± 190 | p < 0.01 |
| CD14+HLA-DR (%) | 80.9 ± 16.5 | 86.2 ± 14.7 | NS |
Data are presented as means ± SD; patients with DFUs (diabetic foot ulcers; n = 68); age, sex, and type of diabetes matched diabetic controls (n = 34); C: complement; PMN: polymorphonuclear; FAGSI: phagocyte stimulation index; NK: natural killers; CD: cluster of differentiation; NS: nonsignificant; p value of significance between patients with DFUs and diabetic controls determined using t-test or Mann–Whitney test.
