Abstract
SUMMARY: COVID-19 is associated with severe disease in pregnancy. Complications of the disease, or simultaneous diagnoses, may be missed if clinicians do not retain a large differential diagnosis when assessing such women. Starvation ketoacidosis is one such diagnosis which may complicate the disease and should not be missed. A 37-year-old woman, 33 weeks' gestation presented with breathlessness. Clinical history, examination and investigations supported a diagnosis of starvation ketosis of pregnancy complicating COVID-19 pneumonitis. Prompt correction of the metabolic disturbance resulted in resolution, and preterm delivery was avoided at this time. Early recognition and prompt management of starvation ketosis of pregnancy in women with COVID-19 are important in reducing maternal and neonatal morbidity and mortality. Preterm delivery may be avoided with prompt resolution of the metabolic disturbance. Clinicians should keep a wide differential diagnosis when assessing women with breathlessness. A multidisciplinary team (MDT) approach is required to facilitate optimal care. LEARNING POINTS: Clinicians should maintain a wide differential when assessing women who are unwell with COVID-19 in pregnancy. Complications such as starvation ketoacidosis are rare but life-threatening. An awareness of such complications facilitates early identification of the condition, and involvement of appropriate specialists who can initiate optimal and timely management. In the context of pregnancy, where ketoacidosis poses a threat to the mother or baby, prompt management and resolution may avoid preterm delivery. Conditions that may increase the risk of developing starvation ketoacidosis include pregnancy, medication use such as corticosteroids or tocolytic therapies, previous gastric surgery, intercurrent illness and pregnancy-related conditions that might contribute towards a degree of chronic starvation. Multidisciplinary input supports the delivery of best practice and care for the patients.
