HbA1c

Over the last decade, diabetes mellitus has emerged as an important clinical and public health problem throughout the world. The aim of the study is   perceive the Potentiality of a newer oral Antihyperglycemic combination therapy over conventional therapy in type 2 diabetes. The prospective study was conducted over a period of six months in the department of Medicine, Guntur City Hospital. The prevalence of type2 diabetes was high in male 65.79 % than female 34.21%. Majority of the patients  (23.68 %) belonged to age group of 51–55 years. Majority of patients (55.26%) having a family history of Diabetes. Majority of patients receiving Combination of Glibenclamide + Metformin (60.53%), evaluated for effect on FPG for both combinations. The mean changes in FPG were noted. In the same way effect on HbA1c also noted. Mean changes in for every month HbA1c will be noted. Our study reveals that Combination therapy with Metformin plus Glimepiride is more effective than Glibenclamide plus Metformin; in improving glycemic control in type 2 diabetes, while also allowing a reduction of the dosage of each drug.

The objective of the study is to compare the analytical performance in terms of precision and accuracy of three methods viz., Immunoturbidimetry (IT), Capillary Electrophoresis (CEP) and High Performance Liquid Chromotography (HPLC) for the measurement of glycosylated haemoglobin (HbA1c). A total of 40 routine patients samples were used for the estimation of HbA1c using the three methods and the results obtained were correlated between the three methods. The correlation coefficient ‘r’ obtained between IT & CEP, IT& HPLC and CEP & HPLC were 0.96, 0.95 & 0.99 respectively, indicating that an ‘r’ value of 0.99 obtained between CEP & HPLC is in agreement with the CLIA guidelines value of > 0.98,while poor ‘r’ values of 0.96 and 0.95 were obtained when IT method was compared with both CEP and HPLC methods. As per this study both CEP & HPLC methods gave good precision and accuracy for Bio-Rad controls. Further, CEP and HPLC methods have provisions to identify interference by Haemoglobin variants present in patient sample. The outcome this study recommends the use of one of the two methods viz., CEP and HPLC for routine measurement of HbA1c.
