Section of Diabetes, Endocrinology and Metabolism

Diabetic ketoacidosis in patients receiving tacrolimus in the post-transplant setting is rare. We describe two such cases in solid-organ transplant recipients. The first patient, a 17-year-old male, presented with severe diabetic ketoacidosis and was managed with intravenous fluids and insulin infusion. He was a known case of Laurence-Moon-Bardet-Biedl syndrome and had received a renal transplant 2 years ago and was receiving tacrolimus since then. Although diabetic ketoacidosis resolved in 24 hours, large doses of subcutaneous insulin (upto 130 units per day) were needed to keep serum glucose within the normal range.
