Diabetes in a Patient with Glycogen Storage Disease Type 1a

Area of Science:

• Metabolic disorders
• Endocrinology
• Genetics

Background:

• Glycogen storage disease type 1a (GSD-1a) is a rare congenital metabolic disorder.
• Improved diagnosis and management have increased life expectancy for GSD-1a patients.
• Concurrent diabetes mellitus in GSD-1a patients is exceptionally rare, complicating glucose management.

Purpose of the Study:

• To investigate effective glucose control strategies for patients with both GSD-1a and diabetes.
• To evaluate the safety and efficacy of specific oral antidiabetic agents in this complex patient profile.

Main Methods:

• Case report of a patient diagnosed with both GSD-1a and diabetes.
• Utilized intermittent continuous glucose monitoring (isCGM) for detailed glucose level tracking.
• Administered α-glucosidase inhibitors (α-GI) and dipeptidyl peptidase-4 (DPP-4) inhibitors for glycemic management.

Main Results:

• The combination therapy of α-GI and DPP-4 inhibitors successfully lowered hyperglycemia.
• No hypoglycemic events were observed during the treatment period.
• isCGM provided valuable insights into glucose fluctuations and treatment effectiveness.

Conclusions:

• α-GI and DPP-4 inhibitors represent a viable treatment option for hyperglycemia in patients with GSD-1a and diabetes.
• This therapeutic approach can improve glycemic control without inducing hypoglycemia.
• Further research is warranted to establish optimal treatment protocols for this rare comorbidity.
