E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
The medical condition to be investigated in this trial is gestational diabetes with insufficient glycemic control by means of dietary adjustments and thus an indication for addiotional pharmacological treatment. |
In deze trial wordt het ziektebeeld diabetes gravidarum onderzocht, waarbij er met dieetaanpassingen onvoldoende glucosecontrole is bereikt en er dus indicatie is voor aanvullende farmacologische behandeling. |
|
E.1.1.1 | Medical condition in easily understood language |
Gestational diabetes, also known as gestational diabetes mellitus, is a condition in which women without previously diagnosed diabetes exhibit high blood glucose (blood sugar) levels during pregnancy. |
Zwangerschapssuikerziekte, ook wel zwangerschapsdiabetes, is een aandoening waarbij vrouwen waarbij niet al eerder suikerziekte is vastgesteld, tijdens de zwangerschap hoge bloedsuikerwaardes hebben. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of treatment with oral hypoglycemic agents (OHA) on the incidence of large-for-gestational-age (LGA) infants in women with GDM requiring medication, compared to conventional insulin (INS) treatment. |
Het evalueren van het effect van behandeling met orale antidiabetica op de incidentie van large-for-gestational-age (LGA) kinderen bij vrouwen met diabetes gravidarum met indicatie voor farmacologische behandeling, in vergelijking met de conventionele behandeling middels insuline. |
|
E.2.2 | Secondary objectives of the trial |
To study the effect of OHA treatment compared with INS treatment, on maternal and perinatal outcome, including maternal hypoglycemia, pregnancy related hypertensive disorders, premature delivery, birth injury, caesarean section, neonatal hypoglycemia and neonatal Medium Care / NICU admission.
To evaluate the effect of OHA compared with INS treatment on cost-effectiveness, both from a societal perspective, and patient perspective (i.e. treatment satisfaction and health-related quality of life).
|
Bestuderen van het effect van behandeling met orale antidiabetica, in vergelijking met insuline behandeling, op maternale en perinatale uitkomsten, waaronder maternale hypoglycaemie, zwangerschapsgerelateerde hypertensieve aandoeningen, partus prematurus, geboortetrauma, keizersnede, neonatale hypoglycaemie en neonatale Medium Care / NICU opname.
Evalueren van het effect van behandeling met orale antidiabetica, in vergelijking met insuline, op de kosteneffectiviteit, zowel vanuit een maatschappelijk perspectief als patientperspectief (tevredenheid behandeling en gezondheidsgerelateerde kwaliteit van leven). |
