Summary

Diabetic nephropathy, a microvascular complication of diabetes, is a progressive kidney disease caused by angiopathy of the capillaries in the kidney glomeruli. Herein, we report a case of a 62-year-old patient with a 30 year history of diabetes, who showed a substantial improvement in diabetic nephropathy on administration of 30 g of Astragalus membranaceus extract per day. After 1 month, estimated glomerular filtration rate increased from 47 to 72 ml/min per 1.73 m2 and was subsequently maintained at the 1-month follow-up. Urinary protein levels also decreased following treatment. Herein, we present and discuss the evidence and mechanism of A. membranaceus on diabetic nephropathy in this patient.

Learning points

  • Diabetic nephropathy is a progressive kidney disease.

  • Angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) are currently used to prevent and delay the progression of diabetic nephropathy. However, their effects are not sufficient to prevent a decline in kidney function.

  • Furthermore, combination therapy with an ACE inhibitor and an ARB can produce adverse effects without additional benefits.

  • In the early phase of diabetic nephropathy, administration of Astragalus membranaceus can be a therapeutic option.

Summary

Silent myocardial ischaemia (SMI), defined as objective evidence of myocardial ischaemia in the absence of symptoms, has important clinical implications for the patient with coronary artery disease. We present a dramatic case of SMI in a diabetes patient who attended annual review clinic with ST elevation myocardial infarction. His troponin was normal on admission but raised to 10.7 ng/ml (normal <0.5) when repeated the next day. His angiogram showed diffused coronary artery disease. We here discuss the implications of silent ischaemia for the patient and for the physician caring for patients with diabetes.

Learning points

  • Silent myocardial ischaemia (SMI) is an important clinical entity.

  • SMI is common and occurs with increased frequency in patients with diabetes.

  • SMI is an independent predictor of mortality.

  • Recognition may lead to early intervention.
