Correlation of Mean Platelet Volume and Red Cell Distribution Width With HbA1c and Its Association With Microvascular Complications in Type 2 Diabetes Mellitus: A Cross-Sectional Study at a Tertiary Hospital in India.

ABSTRACT

INTRODUCTION: Diabetes mellitus type 2 (T2DM) is a metabolic disorder, and its prevalence is rising worldwide. The objective of the study was to investigate the association between mean platelet volume (MPV) and red cell distribution width (RDW) and the glycemic control marker HbA1c. So MPV and RDW could be used as prognostic indicators of deterioration of gluco-regulation in diabetes mellitus type 2 and the associated microvascular complications. METHODOLOGY: A cross-sectional study was conducted on 216 type 2 diabetic patients, who were divided into two groups based on HbA1c values (<7% and >7%). Red blood cell distribution width, mean platelet volume, plasma glucose estimation, fasting lipid profile, spot urine albumin creatinine ratio (ACR), direct ophthalmoscopic examination, and nerve conduction study were tested in all the patients. RESULTS: Of the 216 individuals diagnosed with type 2 diabetes mellitus, 210 exhibited inadequate glycemic control, establishing a statistically significant correlation with triglyceride levels, mean platelet volume, and blood sugar levels. The study revealed a significant association between MPV and RDW and HbA1c levels. Additionally, microvascular complications such as retinopathy, proteinuria, and neuropathy exhibited strong correlations in this patient cohort, emphasizing the interconnectedness of glycemic control and various health indicators in individuals with T2DM. CONCLUSION: This study provides significant results that mean platelet volume and red cell distribution can be used as markers in the diagnosis of microvascular complications in type 2 diabetes mellitus.
