Diabetic ketoacidosis children were divided into 2 groups: euthyroidism (group one, n=30) and ESS (group 2, n=40). C-peptide, glycosylated hemoglobin (HbA1c), bicarbonate, anion gap (AG), free triiodothyronine (FT3), free thyroxine (FT4), and thyrotropin (TSH) levels were measured before and after 7 days of insulin treatment. Daily blood glucose (BG) profiles were recorded.Results: Glycosylated hemoglobin, AG, the mean daily BG, and fasting blood glucose levels were higher, and bicarbonate, FT3, FT4, and TSH levels were lower in group 2 than in group one (all p<0.05). Free triiodothyronine (r=-0.593, p<0.001) and FT4 (r=-0.402, p=0.001) were negatively correlated with HbA1c. Free triiodothyronine (r=-0.438, p<0.001) and FT4 (r=-0.505, p<0.001) were negatively correlated with AG, and FT3 (r=0.503, p<0.001) and FT4 (r=0.448, p<0.001) were positively correlated with bicarbonate.Conclusion: Diabetic ketoacidosis children with ESS have poor diabetic control. Free thyroid hormones are associated with the severity of DKA. %U https://smj.org.sa/content/smj/36/2/243.full.pdf
