Objective: To study various biomarkers in prediction of gestational diabetes mellitus (GDM). Patients and methods: Prospective observational study included 400 pregnant women. Maternal serum sex hormone binding globulin (SHBG), high-sensitive C-reactive protein (hs-CRP), uric acid, creatinine and albumin were measured before 15 weeks of gestation. Patients were followed-up for development of GDM. Results: A total of 269 women were eligible for analysis. GDM complicated 27 (10.03%) of pregnancies. Hs-CRP levels were significantly higher and SHBG levels were significantly lower among women who subsequently developed GDM compared with normoglycemics. Uric acid, albumin and creatinine levels were not significantly different between both groups. For prediction of GDM, hs-CRP at a cutoff value of 2.55 mg/l showed a sensitivity and a specificity of 89% and 55%, respectively. SHBG at a cutoff value of 211.5 nmol/l showed a sensitivity and a specificity of 85% and 37%, respectively. Low SHBG with high hs-CRP predicted GDM with a sensitivity and specificity of 74.07% and 75.62%, respectively with an overall accuracy of 75.46%. Conclusion: Hs-CRP and SHBG are important early predictors of GDM. Adding SHBG to hs-CRP improves specificity and serves good overall accuracy. Uric acid, creatinine and albumin have no role in GDM prediction.
