A comparison of basic characteristics and certain inflammatory markers between the study groups.
| Evaluated parameters | Patients with DFUs (n = 68) | Diabetic controls (n = 34) | p value |
|---|---|---|---|
| Age (years) | 60.3 ± 7.7 | 58.5 ± 6.9 | NS |
| Type of diabetes (type 1/type 2/other types; %) | 16.2/80.9/2.9 | 15.6/84.4/0 | NS |
| Serum glucose level (mmol/L) | 10.8 ± 5.4 | 9.6 ± 3.7 | NS |
| HbA1c according to IFCC (mmol/mol) | 67 ± 19 | 62 ± 21 | NS |
| Serum level of creatinine (μmol/L) | 107.7 ± 58.8 | 84.5 ± 14.3 | p < 0.01 |
| Serum level of CRP (mg/L) | 10.7 ± 14.7 | 2.7 ± 2.2 | p < 0.0001 |
| Serum level of procalcitonin (μmol/L) | 0.07 ± 0.08 | 0.1 ± 0 | NS |
Data are presented as means ± SD; types of diabetes mellitus are in percentages; patients with DFUs (diabetic foot ulcers; n = 68); age, sex, and type of diabetes matched diabetic controls (n = 34); HbA1c: glycosylated hemoglobin; IFCC: International Federation of Clinical Chemistry; NS: nonsignificant; p value of significance between patients with DFUs and diabetic controls determined using t-test or Mann–Whitney test.
