RELATIONSHIP BETWEEN HBA1C LEVELS AND INFLAMMATORY BIOMARKERS (C - REACTIVE PROTEIN, IL6 AND TNF-ALPHA) AMONG TYPE 2 DIABETES MELLITUS-KHARTOUM- SUDAN

Abstract

Introduction: World most prevalence disease, is diabetes mellitus, with countless causes, it on increasing, genetic, lifestyle, infections could all be contributors as causative agents especially type 2 diabetes mellitus, increase inflammatory biomarkers plays extremely critical and vital role in progression of type 2 diabetes mellitus. So this study aimed to assess glycated hemoglobin levels and inflammatory biomarkers among T2DM and find such correlation and compare data with healthy control.

Method: Cross-sectional case control study among 100 case group T2DM and 100 healthy subjects as control group, HbA1c and inflammatory biomarkers, C-reactive protein, IL6 and TNF-alpha were measured for study groups. Enzyme linked immunoassay (ELISA) used for measurement of inflammatory biomarkers TNF-?, CRP, IL6 and Cystatin C. while HbA1c assessed by ichroma device.

Result:  HbA1c, C-reactive protein, IL6 and TNF-alpha were increased among T2DM patients than healthy subjects, giving increased significant difference for each, as p value <0.05. Pearson’s correlation of HbA1c with each of measured parameters showed that HbA1c has positive correlation with inflammatory biomarkers TNF-?. (R= 0.812** P=0.00), CRP(R= 0.527** P=0.00), IL6, (R= 0.778** P=0.00) and Cystatin C (R= 0.884** P=0.00) respectively.

Conclusion: higher levels of inflammatory biomarkers associate with increase with glycated hemoglobin, Improvement of glycemic control reduce risk markers for development of diabetic complications.
