A structured questionnaire was used to collect socio-demographic and clinical-related data. Five milliliters of the blood specimen were collected from each eligible T2 DM patient. Glycated hemoglobin (HbA1c) and red blood cell parameters were determined by Cobas 6000 and DxH 800 fully automated analyzers, respectively. Data were entered into EpiData software version 3.1 and exported to SPSS 25 version for analysis. Independent t-test and Pearson’s correlation coefficient were used to address the research questions. A P-value < 0.05 was considered statistically significant.Results: The mean age of study participants was 51.84± 11.6 years. Moreover, 60.5% of T2 DM patients were in poor glycemic control. There was a significant mean difference between good and poor glycemic controlled T2 DM patients in red blood cell count (4.79± 0.5 vs 4.38± 0.8), hemoglobin (14.13± 1.4 vs 13.60± 1.6), mean corpuscular volume (89.52± 4.7 vs 92.62± 7.5), mean corpuscular hemoglobin (29.63± 1.6 vs 30.77± 2.9), and red cell distribution width (13.68± 1.1 vs 14.63± 1.2) respectively. Red blood cell count was inversely correlated (r=− 0.280, p=0.002) with HbA1c while mean corpuscular volume (r=0.267, p=0.003), mean corpuscular hemoglobin (r=0.231, p=0.010), and red cell distribution width (r= 0.496, p=0.000) were positively correlated with level of HbA1c.Conclusion: Red cell count, mean corpuscular volume, mean corpuscular hemoglobin, and red cell distribution width could be useful indicators to monitor the glycemic status of T2 DM patients instead of HbA1c, though large prospective studies should be considered.Keywords: T2 DM, hyperglycemia, HbA1c, red blood cell parameters |
