Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to utilise ultrasound, using an established method for detecting NAFLD, to determine whether the presence of NAFLD in women with GDM, detected during routine scanning, is a marker of deterioration in glycaemic status post-partum. We propose to assess the relationship between NAFLD and surrogates for insulin resistance as well as glycaemic status, insulin sensitivity and β-cell function, after delivery.

The study is not seeking to compare the incidence of T2DM between those with and without NAFLD. This would require a longer follow-up and larger cohort size. Instead, it aims to quantify the degree of early deterioration of glycaemic status in these groups using insulin resistance markers. This is a clinically important issue as a greater level of insulin resistance would in itself trigger clinical intervention, including vigilant follow-up and empowerment for proactive healthy life style changes, which have been shown to prevent diabetes development .

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pregnant women with GDM

Ultrasound liver scan in addition to routine foetal assessment (antenatal) Metabolic profile blood tests, Oral Glucose Tolerance Test, ELF blood test, repeat liver ultrasound scan and MRI scan (post partum)

MRI scan

Intervention Type DIAGNOSTIC_TEST

On attendance to antenatal clinic with confirmed diagnosis of gestational diabetes based on OGTT and following informed consent: Ultrasound scan: Those with positive OGTT results (i.e. GDM positive) will attend an appointment for an ultrasound scan, as per routine practice. These women will,at that appointment, be assessed for presence/absence of NAFLD as well as undergoing their routine foetal assessment. This is a simple addendum to the existing scan, taking no more than 5 minutes. Participants will have been informed during the consent process that the results (regarding the presence / absence of NAFLD) will be compared to MRI after delivery.
