The incidence rate of diabetic ketoacidosis (DKA) in pregnancy was estimated to be 6.3 per 100,000 maternities, mainly occurring in women with type 1 diabetes in the third trimester. Factors such as infection, vomiting, steroid therapy, and medication errors were major precipitants, with high perinatal mortality rates linked to socio-economic deprivation and complications of diabetes.
Aim To estimate the incidence of diabetic ketoacidosis (DKA) among pregnant women, describe its clinical features, management and outcomes and identify the risk factors for the condition. Methods A national population-based case-control study was conducted in the UK using the UK Obstetric Surveillance System between April 2019 and September 2020 including all pregnant women with DKA irrespective of the level of blood glucose. The incidence rate of DKA in pregnancy was estimated. A case-control analysis limited to women with type 1 diabetes was performed comparing characteristics of women with DKA (cases) to those of women whose pregnancies were not complicated by DKA (controls). Results In all, 82 women were identified with DKA in pregnancy; 6.3 per 100,000 maternities (95% CI: 5.0-7.9). No maternal deaths occurred, but perinatal mortality was 12/73 (16%) with 11 stillbirths and one neonatal death. DKA episodes mostly occurred in women with type 1 diabetes (85%) and in the 3(rd) trimester of pregnancy (71%). Episodes were mainly precipitated by infection (21%), vomiting (21%), steroid therapy (13%) and medication errors (10%). Fifteen percent of women had more than one episode of DKA during their pregnancy. Risk factors associated with DKA among women with type 1 diabetes identified through the case-control analysis were the woman and/or partner not being in a paid employment and having at least one microvascular complication of diabetes before pregnancy. Conclusion DKA in pregnancy was associated with high perinatal mortality and was linked with factors related to socio-economic deprivation, mental health problems and long-term difficulties with glycaemic control.
