We aim to evaluate the serum level of selenium (Se), zinc (Zn), magnesium (Mg), and copper (Cu), the degree of oxidative stress and evaluate their relations to glycemic control in children with T1D. Methods: A case–control study which included 100 diabetic children and 40 healthy children age, sex, and ethnicity-matched as a control group. The diabetic children were divided into poor and good controlled patients according to glycosylated hemoglobin (A1c %). Studied children underwent history taking, clinical examination and laboratory measurement of serum Se, Zn, Mg, and Cu levels, erythrocyte reduced glutathione (GSH) and peroxidase enzyme activity (GPx). Results: Serum Se, Zn, Mg, Cu, erythrocyte GSH, and GPx were significantly lower in the diabetic group in comparison to the control group (P<0.05) and their levels were lower in poorly controlled patients compared to good controlled patients (P<0.05). The serum Se, Zn, Mg, erythrocyte GSH, and GPx showed a negative correlation with A1c %. The serum Se showed a positive correlation with erythrocyte GSH and GPx ([r=0.56, P<0.001], [r=0.78, P<0.001], respectively). Conclusion: Children with T1D, especially poorly controlled cases, had low serum Se, Zn, Mg, Cu, GSH, and GPx. Low serum Se in diabetic children may affect the erythrocyte GSH-GPx system.

In addition, 27 preterm infants without ROP served as controls. All newborn infants in the study were subjected to adequate history taking, full clinical examination, and fundus examination by indirect ophthalmoscope (at 4–6 weeks) as well as determination of serum apelin at birth and at 4–6 weeks of age.Results: The study revealed that oxygen therapy longer than 7 days’ duration, cesarean section (as a mode of delivery), sepsis, mechanical ventilation, blood transfusion, premature rupture of membranes, pneumothorax, perinatal asphyxia, cardiac problems, and neonatal jaundice were considered as risk factors related to development of ROP. Serum apelin levels were significantly lower in patients than controls (P<0.001) at time of diagnosis of the disease (4–6 weeks) while no significant differences were observed in levels at birth.Conclusion: Serum apelin was found to be of significant diagnostic value in the occurrence of ROP.

All newborn infants were subjected to full history taking, clinical examination, routine investigations (cord blood gases and complete blood picture), and assessment of serum CK-BB (cord blood, 6 and 24 hours after birth) and urinary L/C ratio (collected within the first 6 hours, on the 2nd and 3rd day after birth).Results: The serum CK-BB and urinary L/C ratio in infants with HIE were significantly higher in samples collected throughout the monitoring period when compared with the control group (all P<0.001). The cord CK-BB and urinary L/C ratio within the first 6 hours were significantly higher in infants with severe HIE than in infants with mild and moderate HIE (P<0.001). Cord CK-BB level at 12.5 U/L had 100% sensitivity and 84% specificity in the detection of severe HIE infants. Urinary L/C ratio of more than 10.5 collected within the first 6 hours after birth had 100% sensitivity and 78% specificity for the detection of severe HIE infants.Conclusion: The serum CK-BB and urinary L/C ratio in HIE infants were significantly increased early in the course of the disease, which can be used as useful indicators for predicting the development of HIE.
