糖尿病周围神经病变 中国就医指南

Diabetic Peripheral Neuropathy (DPN) is a chronic, progressive nerve disorder that results from prolonged hyperglycemia and metabolic dysregulation in individuals with diabetes mellitus. It primarily affects the peripheral nerves—especially the longest sensory and motor nerves in the feet and hands—leading to distal symmetric polyneuropathy in over 90% of cases. Pathogenesis involves multiple interrelated mechanisms: persistent hyperglycemia triggers oxidative stress, mitochondrial dysfunction, advanced glycation end-product (AGE) accumulation, polyol pathway flux, protein kinase C activation, and neuroinflammation—all contributing to microvascular damage, impaired nerve blood flow, axonal degeneration, and demyelination. Autonomic and proximal neuropathies may also occur but are less common than the classic distal-sensory-predominant form. Epidemiologically, DPN affects approximately 30–50% of people with diabetes globally, with prevalence rising to over 60% in those with long-standing disease (>10 years). In China, where over 141 million adults live with diabetes (IDF 2021), DPN represents the most frequent diabetic complication—and the leading cause of non-traumatic lower-limb amputation. Key modifiable risk factors include poor glycemic control (HbA1c >8%), hypertension, dyslipidemia, smoking, obesity, sedentary lifestyle, and chronic kidney disease; non-modifiable risks include older age, longer diabetes duration, type 2 diabetes onset after age 45, and genetic susceptibility. The clinical spectrum ranges from asymptomatic nerve conduction abnormalities to debilitating symptoms: numbness, tingling, burning pain, electric shocks, allodynia, loss of vibration and temperature sensation, muscle weakness, gait instability, and foot ulceration due to unrecognized trauma. Importantly, up to 50% of patients are asymptomatic at diagnosis—underscoring the need for annual screening via monofilament testing, vibration perception, and neurological examination. Beyond physical morbidity, DPN profoundly impairs quality of life: chronic neuropathic pain correlates strongly with depression, anxiety, sleep disruption, reduced mobility, social isolation, and diminished work capacity. Patients often report decreased independence in daily activities, fear of falling, sexual dysfunction (in autonomic involvement), and substantial healthcare utilization. Early detection, rigorous glycemic and cardiovascular risk factor management, and patient-centered symptom control—including pharmacologic (e.g., duloxetine, pregabalin, gabapentin) and non-pharmacologic strategies (structured exercise, foot care education, cognitive behavioral therapy)—are essential to slow progression and preserve function. Without intervention, DPN can lead to recurrent ulcers, osteomyelitis, Charcot neuroarthropathy, and limb loss—making it not only a neurological condition but a critical public health priority within endocrinology.
