Abstract

Aims: Bespoke glycaemic control strategies following antenatal corticosteroids for women with diabetes in pregnancy (DIP) may mitigate hyperglycaemia. This study aims to identify predictive factors for the glycaemic response to betamethasone in a large cohort of women with DIP. Methods: Evaluation of a prospective cohort study of 347 consecutive DIP pregnancies receiving two doses of 11.4 mg betamethasone 24 h apart between 2017 and 2021 and treated with the Pregnancy‐IVI intravenous insulin protocol. Regression modelling identified factors associated with maternal glycaemic time‐in‐range (TIR) and maternal insulin requirements following betamethasone. Factors associated with neonatal hypoglycaemia (glucose <2.6 mmol/L) in infants born within 48 h of betamethasone administration (n = 144) were investigated. Results: The mean maternal age was 31.9 ± 5.8 years, with gestational age at betamethasone of 33.5 ± 3.4 weeks. Gestational diabetes was present in 81% (12% type 1; 7% type 2). Pre‐admission subcutaneous insulin was prescribed for 63%. On‐infusion maternal glucose TIR (4.0–7.8 mmol/L) was 83% [IQR 77%–90%] and mean on‐IVI glucose was 6.6 ± 0.5 mmol/L. Maternal hypoglycaemia (<3.8 mmol/L) was uncommon (0.47 h/100 on‐IVI woman hours). Maternal glucose TIR was negatively associated with indicators of insulin resistance (type 2 diabetes, polycystic ovary syndrome), late‐pregnancy complications (pre‐eclampsia, chorioamnionitis) and the 1‐h OGTT result. Intravenous insulin requirements were associated with type of diabetes, pre‐eclampsia and intrauterine infection, the 1‐h OGTT result and the timing of betamethasone administration. Neonatal hypoglycaemia was associated with pre‐existing diabetes but not with measures of glycaemic control. Conclusion: An intravenous infusion protocol effectively controls maternal glucose after betamethasone. A risk‐factor‐based approach may allow individualisation of therapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
