Final Diagnosis: Hypoglycemia due to Direct Acting Antiviral Agents

Summary of Hospital Course:

The patient, a 73-year-old female with a history of DM, presented to our clinic complaining of low sugar episodes. She had been receiving insulin therapy for 7 years and had undergone liver transplantation 20 months ago due to HCV infection genotype 1b. Her insulin therapy included intensive subcutaneous insulin injections four times daily, including insulin glargine and insulin aspart. After receiving direct acting antiviral agents (DAAs), the patient began to experience severe hypoglycemia and therefore, the insulin aspart was stopped. The patient discontinued insulin glargine 1 week ago due to persistent hypoglycemia.

During the hospital course, the patient's vital signs were normal and physical examination was unremarkable. Biochemical analysis showed fasting plasma glucose (FG) of 105 mg/dl and postprandial glucose of 200 mg/dl. Glycosylated hemoglobin A1c (HbA1c) was 4.8%, and c-peptide was 3.17 ng/ml. Liver and renal function test results were within the normal reference range. Home blood glucose measurements also showed a normal course of glucose, and the patient was followed only by dietary regulation.

Based on the clinical presentation of the patient, a final diagnosis of hypoglycemia due to direct acting antiviral agents was made. According to the patient's doctor, the patient was discharged with detailed instructions on diet and glucose monitoring. She was advised to schedule an outpatient follow-up with her endocrinologist for further glycemic management.

Instructions:

1. The patient is advised to continue glucose monitoring at home.
2. The patient should maintain a healthy diet as advised by the nutritionist.
3. The patient should follow up with her endocrinologist for further glycemic management.
