Diabetes is often associated with chronic kidney disease (CKD) and is the primary cause of kidney failure in half of patients who receive dialysis therapy. Given the increasing prevalence of diabetes and its high morbidity and mortality, diabetic nephropathy is a serious drawback in individual patients and a tremendous socioeconomic burden on society. Despite growing concern for the management of diabetic nephropathy, the prevalence of CKD with diabetes is the same today as it was 20 years ago. The current strategy to manage diabetic nephropathy, including the control of hyperglycemia, dyslipidemia, and blood pressure and the wide-spread use of renin-angiotensin-aldosterone system inhibitors, is well established to be beneficial in the early stages of diabetic nephropathy. However, the effects are uncertain in patients with relatively progressed CKD. Therefore, early diagnosis or risk verification is extremely important in order to reduce the individual and socioeconomic burdens associated with diabetic nephropathy by providing appropriate management to prevent the development and progression of this condition. This review focuses on recent research and guidelines regarding risk assessment, advances in medical treatment, and challenges of and future treatments for diabetic nephropathy.

Diabetes is an increasing epidemic in Korea, and associated diabetic peripheral neuropathy (DPN) is its most common and disabling complication. DPN has an insidious onset and heterogeneous clinical manifestations, making it difficult to detect high-risk patients of DPN. Early diagnosis is recommended and is the key factor for a better prognosis and preventing diabetic foot ulcers, amputation, or disability. However, diagnostic tests for DPN are not clearly established because of the various pathophysiology developing from the nerve injury to clinical manifestations, differences in mechanisms according to the type of diabetes, comorbidities, and the unclear natural history of DPN. Therefore, DPN remains a challenge for physicians to screen, diagnose, follow up, and evaluate for treatment response. In this review, diagnosing DPN using various methods to assess clinical symptoms and/or signs, sensorineural impairment, and nerve conduction studies will be discussed. Clinicians should rely on established modalities and utilize current available testing as complementary to specific clinical situations.
