    • The present invention provides methods of treatment of patients suffering from the complications of blood sugar disorders: diabetic peripheral neuropathy and diabetic nephropathy by administration of IGF-1 via protein therapy or gene therapy. It relates to methods of treating an individual having a diabetic disorder or a hyperglycemic disorder, comprising administering to the individual an effective amount of a DNA vector expressing IGF-I Eb or IGF-I Ec in vivo or an effective amount of at the IGF-I Eb or IGF-I Ec protein in the early hyperalgesia stage or in patients that have advanced to the hyposensitivity stage. Treatment at the early hyperalgesia stage prevents subsequent hyposensitivity with increases or maintenance of sensory nerve function. IGF-I Eb or IGF-I Ec treatment also increases muscle mass and improves overall mobility, which indicates a treatment-related improvement in motor function. Treatment with IGF-I Eb or IGF-I Ec at the hyposensitivity stage reverses hyposensitivity and improves muscle mass and overall health. Systemic IGF- 1 provides a therapeutic modality for treating hyposensitivity associated with DPN. In addition, IGF-I Eb or IGF-I Ec provides a therapeutic modality for treating diabetic nephropathy. IGF-I Eb or IGF-I Ec improves renal function as evidenced by a modulation in serum albumin concentration and a reduction in urine volume and protein levels. IGF-I Eb or IGF-1 Ec also reduces diabetic glomerulosclerosis.
    • 本发明提供了通过蛋白质治疗或基因治疗施用IGF-1来治疗患有血糖紊乱并发症的患者的糖尿病性周围神经病变和糖尿病性肾病的方法。 本发明涉及治疗患有糖尿病或高血糖病症的个体的方法,包括向个体施用有效量的体内表达IGF-I Eb或IGF-1 Ec的DNA载体或有效量的IGF- I Eb或IGF-I Ec蛋白在早期痛觉过敏阶段或患有进展至低敏感期的患者。 早期痛觉过敏阶段的治疗可通过增加或维持感觉神经功能阻止随后的敏感性。 IGF-I Eb或IGF-I Ec治疗也增加肌肉质量并改善整体移动性,这表明运动功能的治疗相关改善。 IGF-I Eb或IGF-I的治疗在低敏感期反转低敏感性,改善肌肉质量和整体健康。 系统性IGF-1提供治疗与DPN相关的敏感性的治疗方式。 此外,IGF-I Eb或IGF-I Ec提供治疗糖尿病性肾病的治疗方法。 IGF-I Eb或IGF-I Ec改善肾功能,如通过血清白蛋白浓度的调节和尿量和蛋白质水平的降低所证明的。 IGF-I Eb或IGF-1 Ec还可减少糖尿病肾小球硬化。
