Background: To screen patients at average risk for Gestational Diabetes using 50g Glucose Challenge test, to ascertain the prevalence of Gestational diabetes through further diagnostic testing and to prevent and manage complications. Gestational diabetes mellitus (GDM) is defined as carbohydrate intolerance of variable severity with onset or first recognition during pregnancy. Women with GDM are at risk for maternal and foetal complications, so it is important to screen all the pregnant woman.Methods: This study was conducted in 198 patients between 24 and 28 weeks of gestation, attending the Antenatal clinic. 50g oral glucose is administered irrespective of time of the last meal and plasma glucose is measured one hour later. Patients with plasma glucose levels more than 140 mg/dl were subjected to a 100g oral glucose tolerance test, patients with two or more abnormal reading were labelled as GDM and managed accordingly.Results: Prevalence of GDM in our study was 9.59%. Maternal complications like gestational hypertension, vaginal infections and foetal complications were much higher in GDM patients as compare to non GDM group.Conclusions: GDM is a disease which adversely affects both mother as well as foetus. It is concluded that 50 gm glucose challenge test at 24-28 weeks of gestation with a cut-off value of 140 mg/dl is a reliable screening test for GDM. This test offers the best combination of ease and economy of use and reproducibility in screening for gestational diabetes mellitus in average risk patients.

Aim: The Diabetes in Pregnancy Study Group of India (DIPSI, 2010) guidelines recommend the non-fasting 75-g oral glucose challenge test (OGCT) as a single-step screening and diagnostic test for gestational diabetes mellitus (GDM). The aim of this study was to assess the validity of DIPSI criteria by comparing with the World Health Organization (WHO) 1999 criteria of diagnosing GDM. Methods: This study was a hospital based prospective comparative study conducted among 282 pregnant women, of gestational age of 24-28 weeks attending antenatal OPD of Patan hospital. The OGCT was performed on them irrespective of fasting state and without any dietary preparation and they were again asked to come after 3 days of unrestricted carbohydrate diet in fasting state for WHO 2-hour oral glucose tolerance test (OGTT) with 75 gram of glucose load. The value of OGCT >140 mg/dl is diagnostic of GDM (DIPSI 2010). For the reliability of this test, it was compared with WHO 2-hour OGTT. Results: Among the study population, the mean age and BMI was 26.04±4.50 and 24.08±3.30 respectively. Out of 282 patients, 8 cases (2.83%) were found to have abnormal non-fasting 75-g OGCT and 4 cases (1.41%) had abnormal WHO 2-hour OGTT. Paired t test was employed to examine the difference of blood glucose level of the tests. There was statistically significant difference (p<0.001) between the tests. The Sensitivity, specificity, positive predictive value and negative predictive value of oral glucose challenge test was 25%, 97.48%, 12.5% and 98.90% respectively. The non- fasting 75-g OGCT was able to detect only 25% of the cases. Conclusions: Though the non-fasting 75-g OGCT test is cost effective and more compliant to pregnant women, the present report suggests that it cannot be used as a single step screening and diagnostic test because of its low sensitivity. However, it is an adequate alternative for screening test in resources limited areas.

Background: Gestational Diabetes Mellitus (GDM) is associated with several adverse maternal and perinatal outcomes. Thus, screening for early detection of GDM and its treatment is important.Methods: This was hospital based descriptive study done over one year in department of Obstetrics and Gynecology, TUTH, Nepal. Six hundred ninety-seven women fulfilling the inclusion criteria were enrolled at 18-22 weeks of gestation. High risk factors were assessed and GCT was performed in women with risk factors during enrollment. Diagnostic OGTT was performed in women who screened positive (GCT ≥130mg/dl). Screen negative high-risk women were re-screened at 24-28 weeks. In women without known risk factors, GCT was performed at 24-28 weeks and OGTT was performed when screen positive. The diagnosis of GDM was made according to Carpenter and Coustan criteria.Results: Out of 697 enrolled women, 12 were excluded for various reasons and 685 women were analyzed. Women having risk of GDM were 28.9%. The prevalence of GDM was 2.92% and 2.48% with GCT cut off 130 mg/dl and 140 mg/dl respectively. Lowering the threshold to 130 mg/dl identified three extra cases (p=0.010). The prevalence among high risk group was 8.58% and 7.07% with the cut off value 130 mg/dl and 140 mg/dl respectively with three extra cases detected on taking cut off value 130 mg/dl (p=0.014). Among low risk women the prevalence of GDM was same i.e. 0.61% with both the cut off values.Conclusions: Lowering threshold of GCT to 130 mg/dl could identify significant percentage of extra cases of GDM especially in high risk women.
