Fulminant and Slowly Progressive Type 1 Diabetes Associated with Pregnancy

Area of Science:

• Endocrinology
• Reproductive Medicine
• Autoimmune Diseases

Background:

• Type 1 diabetes presents in three clinical subtypes: fulminant, acute-onset, and slowly progressive (latent autoimmune diabetes in adults).
• Fulminant and slowly progressive type 1 diabetes can occur during pregnancy, termed pregnancy-associated type 1 diabetes.
• Fulminant type 1 diabetes poses significant maternal and fetal risks due to sudden onset and potential ketoacidosis.

Purpose of the Study:

• To highlight the distinct clinical presentations and management strategies for pregnancy-associated type 1 diabetes.
• To emphasize the importance of early diagnosis and intervention for fulminant type 1 diabetes in pregnancy.
• To outline monitoring protocols for gestational diabetes patients at risk for postpartum slowly progressive type 1 diabetes.

Main Methods:

• Clinical classification of type 1 diabetes subtypes.
• Identification of risk factors and diagnostic criteria for pregnancy-associated type 1 diabetes.
• Review of management guidelines for hyperglycemia and autoimmune diabetes in pregnancy.

Main Results:

• Fulminant type 1 diabetes in pregnancy is characterized by marked hyperglycemia (≥288 mg/dL) and relatively low HbA1c (<8.7%) in women without prior diabetes history.
• Gestational diabetes patients with positive anti-islet autoantibodies are at high risk for postpartum slowly progressive type 1 diabetes.
• Immediate insulin therapy is recommended for suspected fulminant type 1 diabetes during pregnancy.

Conclusions:

• Prompt recognition and insulin treatment are vital for managing fulminant type 1 diabetes in pregnant individuals.
• Postpartum surveillance for slowly progressive type 1 diabetes is essential in at-risk gestational diabetes patients.
• Distinguishing and managing these subtypes of type 1 diabetes during pregnancy is critical for maternal and fetal outcomes.
