Investigating the Relationship between hs-CRP Serum Level and Insulin Resistance (HOMA IR) Six Weeks after Childbirth in Patients with Gestational Diabetes Mellitus

Background: Some patients with GDM (Gestational Diabetes Mellitus) still experience impaired glucose tolerance after childbirth and will be affected by diabetes mellitus type 2. Objectives: The aim of this study is to investigate the relationship between hs-CRP serum levels with insulin resistance six weeks after childbirth in patients with gestational diabetes mellitus type 2. Methods: In this descriptive cross-sectional study, 110 patients with GDM were evaluated in terms of the insulin resistance index (HOMA), hs-CRP serum, and the oral glucose tolerance test (OGTT) six weeks after childbirth. Their anthropometric indices were measured in the early pregnancy. Spearman&rsquo;s rank correlation coefficient and linear regression analysis were used to analyze data in SPSS 16. Results: The mean of hs-CRP was 8.72 &micro;g/ml among the patients in this study. It is higher than the normal range. Moreover, 24.5% of the patients were suffering from impaired glucose tolerance, and hs-CRP levels were higher than the normal range in 92.6% of these patients. Furthermore, 41.8% of patients showed insulin resistance, and hs-CRP levels were high among 73.9% of them. After age adjustment, the increase in hs-CRP serum level was significantly correlated with insulin resistance (HOMA) and the one-hour and two-hour OGTTs (p=0.007 and p<0.001, respectively). Conclusion: It appears that age adjustment can help us figure out the relationship between the increase in hs-CRP serum and insulin resistance in pregnant mothers with diabetes six weeks after childbirth.
