[Results of screening tests for gestational diabetes mellitus at Medical University in Warsaw]

Abstract

Our purpose was to determine the incidence of screening for gestational diabetes among the population of women delivering at I and II Departments of the First Faculty of Medical University in Warsaw. A retrospective review of 647 pregnancies was performed. The incidence of gestational diabetes mellitus screening was determined and the rate of occurrence of GDM analyzed. 310 (48%) pregnancies were screened for gestational diabetes mellitus with a 1-hour, 50 gm oral glucose challenge test. 49 (16.07%) of the screens had positive results at a plasma glucose level of > 139 mg/dl. Two-hour 75 gm oral glucose tolerance tests (according to the 1994 World Health Organization panel recommendations) were performed on screen-positive women, eleven of whom (22.45%) were diagnosed with gestational diabetes mellitus. Despite of positive oral 50 gm glucose test, (plasma glucose level 140-179 mg/l) 15 women (30%) haven't had the 75 gm oral glucose test. The incidence of GDM among analyzed population is 4% and when GDM screening is carried out, exceeds 7%. Early gestational glucose screening, if performed, may be beneficial in detecting gestational diabetes. Consideration should be given to fulfill it more frequently and for sure, repeat glucose testing in patients with positive one-hour screening tests.
