The measured concentration of CRP was of 5.29 ± 1.82 μg/mL (p = 0.038 for G02 vs G01 and G03; p < 0.01 for G02 vs control group G05) and 4.21 ± 1.37 μg/mL (p = 0.024 for G04 vs G01 and G03; p = 0.011 for G04 vs G05) in groups of GDM and T2DM that gave birth of newborns with clinical signs of DF, whereas groups with healthy newborns demonstrated CRP comparable with the levels in control group G05 and made 2.04 ± 1.32 μg/mL (p = 0.54 for G01 vs G05) and 2.84 ± 0.67 μg/mL (p = 0.47 for G03 vs G05; Table 3). This evidence concerns the gene CRP and dengue disease.
