糖尿病肾病 中国就医指南

Diabetic nephropathy (DN) is a progressive kidney disease that develops as a microvascular complication of diabetes mellitus—primarily type 1 and long-standing type 2 diabetes. It represents the leading cause of end-stage kidney disease (ESKD) worldwide, accounting for nearly 40–50% of all new dialysis initiations in high-income countries and an increasingly large proportion in rapidly urbanizing regions like China. Pathogenically, DN arises from sustained hyperglycemia-induced metabolic, hemodynamic, and inflammatory insults to the glomerulus and tubulointerstitium. Key mechanisms include activation of the polyol and hexosamine pathways, accumulation of advanced glycation end-products (AGEs), oxidative stress, renin-angiotensin-aldosterone system (RAAS) overactivity, podocyte injury, and endothelial dysfunction. These processes culminate in glomerular basement membrane thickening, mesangial expansion, podocyte loss, and progressive glomerulosclerosis—manifesting clinically as persistent albuminuria (initially microalbuminuria, then macroalbuminuria), declining estimated glomerular filtration rate (eGFR), hypertension, and eventual renal failure. Epidemiologically, approximately 20–40% of people with diabetes develop DN over their lifetime; prevalence rises sharply with diabetes duration (>15 years), poor glycemic control (HbA1c >8%), and coexisting hypertension or dyslipidemia. In China—home to over 140 million adults with diabetes—the burden is escalating, with DN contributing to ~25% of incident ESKD cases annually. Major modifiable risk factors include suboptimal blood glucose control, uncontrolled hypertension (especially systolic BP >130 mmHg), smoking, obesity, sedentary lifestyle, and genetic susceptibility (e.g., APOL1 variants in certain populations). Non-modifiable risks include longer diabetes duration, male sex, older age at diagnosis, and type 1 diabetes onset before age 20. Beyond physiological decline, DN profoundly impairs quality of life: patients experience fatigue, sleep disturbances, dietary restrictions (low-protein, low-sodium, potassium-phosphorus management), anxiety about dialysis or transplant, financial strain, reduced work capacity, and social isolation. Early detection via annual urinary albumin-to-creatinine ratio (UACR) and eGFR monitoring is critical—intervention at the microalbuminuric stage can delay progression by up to 50%. Without timely multidisciplinary care—including nephrology, endocrinology, dietetics, and behavioral support—patients face accelerated functional decline, cardiovascular morbidity (DN doubles CVD mortality risk), and premature mortality. Comprehensive management emphasizes strict glycemic targets (individualized HbA1c 6.5–7.5%), BP control (<130/80 mmHg, preferably with ACEi or ARB), SGLT2 inhibitors (proven renal and cardiovascular benefits), GLP-1 receptor agonists, lipid management, smoking cessation, and nutritional counseling. As DN advances, treatment shifts toward renal replacement therapy planning—timely referral to nephrology (ideally ≥6–12 months before anticipated ESKD) improves transplant candidacy and survival outcomes.
