Erythropoietin can deteriorate glucose control in uraemic non-insulin-dependent diabetic patients.
Two patients with non-insulin-dependent diabetes mellitus (NIDDM) and moderate chronic renal failure experienced a worsening of glycaemic control when recombinant human erythropoietin (r-HuEPO) was introduced, leading to insulin therapy. A 71-year-old woman with a 20-year history of NIDDM had presented histologically documented diabetic nephropathy for 2 years during which glucose control was stabilized by a diet and glibenclamide 10 mg. In the 6 months following introduction of r-HuEPO, hyperglycaemic symptoms developed, and HbA1C increased from 8.9% to 12.3%. During this period, no intercurrent events occurred, except epistaxis due to accelerated hypertension one month after r-HuEPO was started. A 62-year-old man had a 15-year history of NIDDM, with proliferative retinopathy, macroproteinuria and chronic renal failure for 4 years. The day after the first injection of r-HuEPO, capillary glucose level rose dramatically. In both of these cases, antihypertensive treatment was increased and insulin introduced. The role of r-HuEPO in hyperglycaemia was probable in the first case and highly probable in the second. Reports about the effects of r-HuEPO on glucose metabolism in uraemic patients are conflicting. Short- and long-term effects can differ, although long-term benefit is likely. The fact that our patients were not dialized may have been important. Clinicians should be aware that glucose control may deteriorate with r-HuEPO, requiring some uraemic NIDDM patients to undergo insulin therapy.
