Awareness of euglycaemic diabetic ketoacidosis during pregnancy prevents recurrence of devastating outcomes: a case report of two pregnancies in one patient

BACKGROUND: Euglycaemic diabetic ketoacidosis (DKA) during pregnancy is a life-threatening obstetric emergency. It requires early identification and prompt action. Obstetricians’ knowledge about symptoms, diagnostic pitfalls and management during pregnancy and delivery need to be improved. We report a case of a young diabetic woman developing severe euglycaemic DKA in two consecutive pregnancies; the first pregnancy resulted in the most deviating outcome (i.e., intrauterine death), while the second pregnancy resulted in the delivery of a healthy newborn. Thus, the novelty of the case presented here is the possibility to demonstrate how the management of DKA in pregnancy can dramatically change outcomes. CASE PRESENTATION: We report a case of a young diabetic woman in whom DKA was concealed by hyperemesis and oesophageal reflux. This woman presented to our delivery unit with severe euglycaemic DKA during her first pregnancy. While the mother’s condition could be successfully stabilized, the foetus died shortly after admission. Two years later, the same woman presented with similar problems. Repeated episodes of mild euglycaemic DKA could be successfully managed with consequent interdisciplinary treatment and close observation, leading to a good pregnancy outcome, i.e., the birth of a healthy child. CONCLUSION: Awareness of euglycaemic DKA needs to be increased to reduce the risk of severe complications during pregnancies in diabetic women. This case report demonstrates that increased awareness of DKA with immediate recognition and a successful multidisciplinary approach are mandatory for an positive pregnancy outcomes.
