Application of Dorzagliatin in peritoneal dialysis patients with type 2 diabetes mellitus: A case report.

Abstract

Background: Treating diabetes in dialysis patients remains a challenge, with many hypoglycemic drugs requiring dose adjustments or avoidance in these patients.

Case summary: This report describes an 83-year-old female patient with a 30-year history of type 2 diabetes (T2DM) who had struggled to control her blood sugar for more than a year. She had a history of high blood pressure for 30 years, had undergone continuous ambulatory peritoneal dialysis for more than two years, was 163 cm tall, weighed 77 kg, and had a body mass index of 28.98 kg/m². Despite intensive insulin therapy at a daily dose of 150 units, adding Dorzagliatin at a dosage of 75 mg orally twice daily led to immediate blood sugar improvement and a gradual reduction in insulin dosage. After one month of follow-up, the fasting plasma glucose was 6-8 mmol/L, and the 2-hour postprandial glucose was 8-12 mmol/L.

Conclusion: To our knowledge, this report is the first to use Dorzagliatin to treat type 2 diabetes peritoneal dialysis patients with challenging glucose control. Dorzagliatin, a novel glucokinase activator primarily metabolized by the liver, exhibits no pharmacokinetic differences among patients with varying degrees of chronic kidney disease. It has a high plasma protein binding rate and may not be cleared by peritoneal dialysis, potentially offering a new glycemic control option for Type 2 diabetic patients on peritoneal dialysis.
