摘要
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-1Eb or IGF-1Ec in vivo or an effective amount of at the IGF-1Eb or IGF-1Ec 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-1Eb or IGF-1Ec treatment also increases muscle mass and improves overall mobility, which indicates a treatment-related improvement in motor function. Treatment with IGF-1Eb or IGF-1Ec 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-1Eb or IGF-1Ec provides a therapeutic modality for treating diabetic nephropathy. IGF-1Eb or IGF-1Ec improves renal function as evidenced by a modulation in serum albumin concentration and a reduction in urine volume and protein levels. IGF-1Eb or IGF-1Ec also reduces diabetic glomerulosclerosis.
