Mapowanie cyklu miesiączkowego podczas stosowania zamkniętej pętli dostarczania insuliny (MCM-Loop)
Mapowanie Cyklu Miesiączkowego Podczas Stosowania Zamkniętej Pętli Dostarczania Insuliny
Hipoteza zakłada, że cykliczność miesiączkowa wpływa na metabolizm glukozy i energii u kobiet z cukrzycą typu 1. Uzasadnienie hipotezy dotyczącej wpływu cyklu opiera się na założeniu, że wahania hormonów płciowych żeńskich w trakcie cyklu miesiączkowego powodują zmiany w fizjologicznych parametrach metabolizmu glukozy i homeostazy energii oraz/lub aspektach stylu życia związanych z regulacją poziomu glukozy we krwi i masy ciała. Oczekuje się, że wahania hormonów wpływają na wrażliwość na insulinę, opróżnianie żołądka, zachowania żywieniowe i wydatek energetyczny. Przewiduje się, że wrażliwość na insulinę jest najwyższa w fazie przedowulacyjnej, a najniższa w środkowej fazie lutealnej. Dodatkowo oczekuje się, że opróżnianie żołądka osiąga szczyt w fazie folikularnej, a najwyższy wydatek energetyczny i spożycie pokarmu występują w środkowej fazie lutealnej.
Głównym celem tego badania jest scharakteryzowanie metabolizmu glukozy i energii w trakcie cyklu miesiączkowego u kobiet z cukrzycą typu 1, które mają naturalne cykle. Dalszymi celami są ocena wpływu cyklu miesiączkowego na kontrolę glikemii i zapotrzebowanie na insulinę, zbadanie, jak wahania poziomu hormonów płciowych wpływają na metabolizm glukozy i energii, oraz określenie zarówno międzyosobniczej, jak i wewnątrzosobniczej zmienności w zmianach metabolicznych związanych z cyklem miesiączkowym. Dodatkowo badanie oceni, czy zmiany w kluczowych fizjologicznych składnikach metabolizmu glukozy i czynnikach behawioralnych pośredniczą w wariacjach związanych z cyklem miesiączkowym w kontroli glikemii i zapotrzebowaniu na insulinę.
