The comparison of serum levels of immunoglobulins including IgG subclasses among patients with chronic DFUs infected by sensitive and resistant pathogens and diabetic controls. Data are presented as means ± SD; patients with DFUs (diabetic foot ulcers) infected by sensitive (subgroup S; n = 50) or resistant pathogens (subgroup R; n = 18). Age, sex, and type of diabetes matched diabetic controls (n = 34); Ig: immunoglobulin; p value of significance between patients with DFUs infected by sensitive (subgroup S) or resistant pathogens (subgroup R) and diabetic controls determined using Kruskal-Wallis one way analysis of variance test. † p < 0.01: mean serum levels of IgA, IgG, and IgG1 in subgroup S versus diabetic controls. ‡ p < 0.05: mean serum levels of IgG in subgroup S versus subgroup R. # p < 0.01: mean serum levels of IgG4 in subgroup S versus subgroup R.
