Menstruale Cyclus Mapping Tijdens het Gebruik van Gesloten-Lus Insuline Toediening (MCM-Loop)
Menstruale Cyclus in Kaart Brengen Tijdens Gebruik van Gesloten-Lus Insulineafgifte
De hypothese is dat de menstruatiecyclus invloed heeft op de glucose- en energiemetabolisme bij vrouwen met diabetes type 1. De onderbouwing van de hypothese over cyclus-effecten is gebaseerd op de aanname dat schommelingen in vrouwelijke geslachtshormonen gedurende de menstruatiecyclus veranderingen veroorzaken in fysiologische parameters van glucosemetabolisme en energiehomeostase en/of leefstijlfactoren die betrokken zijn bij de regulatie van bloedglucose en lichaamsgewicht. Er wordt verwacht dat hormoonschommelingen de insulinegevoeligheid, maaglediging, eetgedrag en energieverbruik beïnvloeden. Er wordt verwacht dat de insulinegevoeligheid het hoogst is in de pre-ovulatiefase en het laagst in de mid-luteale fase. Verder wordt verwacht dat de maaglediging een piek bereikt in de folliculaire fase, en dat het hoogste energieverbruik en de hoogste voedselinname optreden tijdens de mid-luteale fase.
Het primaire doel van deze studie is het karakteriseren van glucose- en energiemetabolisme gedurende de menstruatiecyclus bij vrouwen met diabetes type 1 die een natuurlijke cyclus hebben. Verdere doelstellingen zijn het beoordelen van de impact van de menstruatiecyclus op de glucosecontrole en insulinebehoefte, het onderzoeken hoe schommelingen in geslachtshormoonspiegels het glucose- en energiemetabolisme beïnvloeden, en het kwantificeren van zowel inter- als intra-individuele variabiliteit in metabole veranderingen gerelateerd aan de menstruatiecyclus. Daarnaast zal de studie evalueren of veranderingen in belangrijke fysiologische componenten van glucosemetabolisme en gedragsfactoren de menstruatiecyclusgerelateerde variaties in glucosecontrole en insulinebehoefte mediëren.
