Introduction: There are low and conflicting data about the relationships between homocysteine, adiponectin/ homocysteine ratio and uric acid with insulin resistance indexes in gestational diabetes mellitus (GDM). Therefore, this study was performed with aim to evaluate serum values of homocysteine, adiponectin, adiponectin/ homocysteine ratio and uric acid and their relationships with insulin resistance index in GDM compared with normal pregnancy.
Methods: This cross-sectional study was performed on 30 women with GDM and 30 normal pregnant women referred to Asalian hospital of Khorramabad during 2013-2014. Serum levels of glucose and uric acid were measured by photometric method and serum levels of homocysteine, adiponectin and insulin were measured by ELISA method. Data was analyzed by independent t-test and Pearson’s correlation analysis. PResults: Serum levels of homocysteine were significantly increased in GDM compared with normal pregnant women (P<0.001); while levels of adiponectin (P=0.003) and adiponectin/ homocysteine ratio (P=0.001) were significantly decreased. There was no significant difference in uric acid level between two groups. Significant and direct correlation was observed between levels of homocysteine and insulin with GDM (r=0.40, P=0.031). There was significant and direct correlation between levels of uric acid with insulin resistance index in experimental group (r=0.38, P=0.041). An indirect and significant correlation was observed between adiponectin/ homocysteine ratio and fasting blood glucose in normal control group (r= -0.39, P=0.035).
Conclusion: Increased serum values of homocysteine and decreased values of adiponectin/ homocysteine ratio and lightly increased levels of uric acid could be considered as risk factors for insulin resistance in GDM.
