Glycated Haemoglobin Determination in the Biological Follow-Up of Diabetic Subjects Admitted to the Endocrinology Department of the CNHU-HKM of Cotonou

Abstract

Introduction: One of the biological markers for monitoring glycaemic control in diabetic patients is glycated protein. The definition of a reference method to improve the accuracy of measurement tools is necessary. The aim of our study was to assess the glycemic control of diabetic patients based on glycated hemoglobin. Patients and Method: This is a descriptive cross-sectional study conducted in April 2021 at the national university hospital center (CNHU-HKM) of Cotonou. All patients who consulted during the period and who gave their consent were included. After collecting the blood samples according to the classical standards of the pre-analytical phase, we measured the blood glucose level and the HbA1c. Results: The mean blood glucose level of the patients was 1.52 ± 0.16 g/L with extremes of 0.80 g/L and 3.5 g/L. The mean HbA1c proportion was 8.39% ± 0.60% with a minimum and maximum value of 5.40% and 16% respectively. We also noted that the mean body mass index (BMI) of the patients was 28.61 ± 1.46 Kg/m 2 with extremes of 17.50 Kg/m 2 and 46.02 Kg/m 2 . Oral anti diabetic and hygienic-dietary measures were used by 44 patients (80%) and hygienic-dietary measures (HDM) only used by 9.09%. A frequency of 87.53% of patients had at least one degenerative complication. Retinopathy was the most observed degenerative disease (36.36%) followed by cardiovascular disease (25.45%). Conclusion: This study showed that there is a poor correlation between fasting blood glucose and glycated haemoglobin levels, which could be due to several biological and clinical reasons. It also showed that despite the respect of hygienic dietary measures and a well conducted treatment, it is difficult to obtain a satisfactory glycemic balance in obese patients.
