The article discusses the incidence and management of hypoglycemia and diabetic ketoacidosis (DKA) in pregnancy. Additional topics addressed are the incidence of hypoglycemia, pathophysiology, diagnosis and management of hypoglycemia in pregnancy, fetal monitoring with short- and long-term fetal sequelae, and prevention of hypoglycemic recurrences. Subsequently, attention is focused on the diagnosis and management of hyperglycemia and DKA in pregnancy.
Decompensated hyperglycemia is a frequent, severe complication of diabetes mellitus. Ketoacidosis usually occurs in patients with insulin-dependent (type I) diabetes, and insulin therapy is required to correct their hyperglycemic derangement. Hyperosmolar nonketotic state is more common in patients with non-insulin-dependent (type II) diabetes, who usually present with severe dehydration and hyperosmolar plasma. They respond readily to aggressive volume expansion, and insulin has a lesser role in management. Some patients exhibit a mixture of ketoacidosis and hyperosmolarity, which suggests that the two conditions may represent variants of decompensated hyperglycemia that differ only by the magnitude of dehydration and the severity of acidosis. All diabetic patients with hyperglycemic decompensation should return to their usual hypoglycemic programs as soon as possible and receive close follow-up after hospitalization.
The development of diabetic ketoacidosis is an unusual complication of a glucagon-secreting pancreatic islet cell neoplasm, with only four reported cases in the literature. In this article, the authors report on a 46-year-old woman with a glucagonoma cosecreting pancreatic polypeptide, somatostatin, and serotonin diagnosed 8 months before the onset of diabetic ketoacidosis. She was treated with hydration, insulin, and octreotide, with improvement in her clinical course and a decrease in the glucagon, pancreatic polypeptide, and chromogranin A plasma levels. With the addition of weekly 5-FU, she has maintained a partial radiographic response and has had no further episodes of diabetic ketoacidosis for a 4.5-year period. Diabetic ketoacidosis can develop in the presence of a glucagonoma, and the pathophysiology remains unknown.
