HbA1c levels in patients with gestational diabetes mellitus: Relationship with pre- pregnancy BMI and pregnancy outcome

摘要

Background/Aims: The use of glycated hemoglobin (HbA1c) measurement in gestational diabetes mellitus (GDM) is controversial. Aim of the present study was to determine HbA1c levels in a series of GDM patients, in order to verify the possible contribution of HbA1c to GDM management. Materials/Subjects and methods: The study included 148 caucasian GDM patients. GDM screening was performed between the 24th and the 28th week of gestation by a two-step procedure, according to the 4th and 5th International Workshop Conference on Gestational Diabetes Mellitus recommendations. Exclusion criteria were: preexisting diabetes, corticosteroid therapy, history of asthma or hypertension, known fetal anomaly, history of previous stillbirth, preterm delivery considered to be likely for either maternal disease or fetal conditions. HBA1c was determined by a standard HPLC technique. Results: At GDM diagnosis, all HbA1c levels were 5.6. ROC analysis showed that HbA1c at diagnosis and before delivery resulted a good predictor of adverse pregnancy outcome. Conclusions: The present results indicate that HbA1c levels could be of help in predicting adverse pregnancy events. (C) 2013, Editrice Kurtis
