The current status of gestational diabetes mellitus in Australia reveals an almost quadrupling prevalence over the last decade. A narrative review of the current Australian literature reveals unique challenges faced by Australian maternity clinicians when addressing this substantial disease burden in our diverse population. Rising rates of maternal overweight and obesity, increasing maternal age and the diversity of ethnicity are key epidemiological impactors, overlaid by the 2015 changes in screening and diagnostic parameters. Our vast land mass and the remote location of many at risk women requires innovative and novel ideas for pathways to diagnose and effectively manage women with gestational diabetes mellitus. By modifying and modernizing models of care for women with gestational diabetes mellitus, we have the ability to address accessibility, resource management and our acute response to global events such as the COVID 19 pandemic. With continuing research, education and robust discourse, Australia is well placed to meet current and future challenges in the management of gestational diabetes mellitus.

Background Bile acid levels and liver function tests may be normal at presentation in women with intrahepatic cholestasis of pregnancy. The biochemical results of patients presenting with pruritus typical for intrahepatic cholestasis of pregnancy were reviewed. Methods A retrospective audit of women coded as having intrahepatic cholestasis of pregnancy over a three-year period. Results One hundred and ninety-three women (1.1% of the obstetric population) presented with pruritus typical of intrahepatic cholestasis of pregnancy. Forty (21%) of these women had normal biochemistry at presentation, half subsequently developing abnormal results. Women with a history of allergic reactions were more likely to develop intrahepatic cholestasis of pregnancy. Conclusions Normal biochemistry should not preclude a trial of ursodeoxycholic acid in women with distressing pruritus typical for intrahepatic cholestasis of pregnancy. Biochemical tests which are more sensitive and specific in the diagnosis of intrahepatic cholestasis of pregnancy would be valuable. Investigation of other populations with intrahepatic cholestasis of pregnancy regarding a possible association with atopy/allergy would be interesting.

Background To determine the prevalence and outcomes of intrahepatic cholestasis of pregnancy. Methods A review comparing intrahepatic cholestasis of pregnancy pregnancies to all other pregnancies in three tertiary care Australian hospitals over a 36-month period. Results There were 43,876 pregnancies. The prevalence of intrahepatic cholestasis of pregnancies ( n = 319) was 0.7%. There were differences between intrahepatic cholestasis of pregnancy and non-intrahepatic cholestasis of pregnancy mothers including higher prevalence of South Asian (22.6% versus 3.1%, p < 0.001), Indigenous Australian (3.8% versus 1.8%, p < 0.05), and Asian ethnicity (8.4% versus 5.7%, p < 0.05), mothers with a body mass index >35 kg/m2 (10.6% versus 5.5%, p < 0.001), those with diabetes mellitus (25.7% versus 9.8%, p < 0.001), and those with twin births (8.7% versus 2.2%, p < 0.001). The primary clinical outcomes of intrahepatic cholestasis of pregnancy included a median gestational age at delivery of 36.4 (SE 0.09) weeks compared to 38.6 (SE 0.01) weeks (p < 0.001), a lower birth weight (3.12 (SE 0.03) versus 3.31 kg (SE 0.03), p < 0.001), and an increase in special care nursery admissions (44.5% versus 15.3%, p < 0.001). Conclusion Treated intrahepatic cholestasis of pregnancy in the population described here had similar mortality outcomes although increased special care nursery admission as compared to the general population.
