Importance of HbA1c and Fructosamine As A Marker Of Glycemic Control and Evaluation Of Some Biochemical Parameters During Pregnancy

Abstract

Objective: Controlling and monitoring the diabetes during pregnancy, because of the malformation, macrosomia and other complications is especially important. Our study is designed to investigate the reliability of the two most commonly used parameter is the hemoglobin A1c (HbA1c) and fructosamine during pregnancy. Also among our study group, serum total protein, albumin, vitamin B12, folic acid, glucose, insulin, ferritin and hemoglobin data were evaluated. Methods: The study groups are pregnant women (n=252; age mean: 27,761± 5/year) and control group (n=28; age mean: 28,61± 5,38/year) who are no additional health problems. Diabetic pregnant women number is 124 (consisted of 10 first trimester, 62 second trimester and 52 third trimester) and nondiabetic pregnant women number is 138 (consisted of 24 first trimester, 32 second trimester and 82 third trimester). All measurement data are obtained from hospital information system. Results: No statistically significant difference in any of the groups for HbA1c. It’s clearly observed that all the significant differences found for fructosamine occur depending on the level of albumin and fructosamine levels decreased progressively during the three trimesters. In our diabetic pregnant women group; although statistically make a difference; mean blood glucose values were below our expectations. Conclusion: Our study is support that fructosamine and HbA1c are unavailable for diagnosis and monitoring the gestational diabetes. However the lack of difference between the groups for levels of fructosamine and HbA1c; and blood glucose levels below our expectations in diabetic pregnant women group can be connected good diabetes control.
