Abstract

PROBLEM TO BE SOLVED: To obtain the subject agent containing an insulin-like growth factor 1 or its analogue and excellent in preventing and treating effects on steroid myopathy which is adverse effect as muscle weakness, muscle atrophy, etc., accompanied by treatment with steroids. SOLUTION: This preventing and treating agent contains an insulin-like growth factor 1, e.g. derived from human (IGF-1) or its active analogue (e.g. O-glucosylated IGF-1, a variant protein having IGF-1 activity, in which a part of amino acid sequence of IGF-1 is inserted, replaced, loosen or added). The agent is formulated into a form such as a solid preparation e.g. tablet or capsule, a semisolid preparation e.g. ointment or cream, a liquid preparation e.g. solution or suspension, liposome agent, and the resultant preparation is once or dividedly administered in a daily dose of 0.1-10mg/kg, especially 0.2-2mg/kg expressed in terms of IGF-1 amount.

BACKGROUND OF THE INVENTION Steroid myopathy is a variety of steroids (eg, triamcinolone acetonide, dexamethasone, betamethasone, hydrocortisone, etc.) for the treatment of collagen diseases, autoimmune diseases such as polymyositis, asthma and inflammation. Is a lesion that often develops as a side effect when administered continuously. In particular, lesions are likely to appear on type II fibers of muscle. Usually, muscle weakness and muscle atrophy gradually start from the lower limb proximal muscle and then spread to the upper limb proximal muscle, the lower limb and the upper limb distal muscle, the thigh muscle, and the trunk muscle. Although recovery from steroid withdrawal may occur, there are no active preventive or therapeutic agents.

IGF-1 is a naturally occurring polypeptide that can be isolated from many sources. IGF-1 can be produced synthetically or by genetic engineering. IGF
-1 is a mediator when growth hormone (GH) exerts a bone growth promoting action. When GH binds to the GH receptor of the chondrocyte precursor cell membrane existing at the epiphysis of the long bone to transmit a signal, IGF-1 production is promoted. Chondrocyte progenitor cells and chondrocytes not only have the ability to produce IGF-1, but also express IGF-1 receptor on their cell membranes, and thus repeat differentiation and proliferation to promote bone formation and In the vertical direction. GH for treatment of GH deficient short stature
GH is ineffective for the treatment of laron type short stature patients whose administration is effective but whose GH receptor is abnormal, and the treatment with IGF-1 is approved. IGF-1 is also known as a hormone having a blood glucose lowering action together with insulin. Insulin exerts its effect via the insulin receptor, whereas IGF-1
It binds to both the GF-1 receptor and the insulin receptor and exerts its action. Therefore, a therapeutic agent for a patient suffering from diabetes due to impaired insulin receptor and subsequent signal transduction process such as insulin receptor dysfunction type A and B, lipoatrophic diabetes mellitus, spermosis, Loveson-Mendenhol syndrome Is approved for use as IGF-1. However, its use as a prophylactic / therapeutic agent for steroid myopathy is not known.

Test Example (Test Method) SD rats were divided into 3 groups (4 animals in each group), a control group, a steroid administration group, and a steroid +
This is the IGF-1 administration group. Triamcinolone acetonide (manufactured by SIGMA) was selected as the steroid.
75 mg / kg / day is dissolved in dimethyl sulfoxide for administration, and IGF-1 is 2 mg / kg / day in 0.2% BSA-physiological saline solution for administration. All were subcutaneously administered for 2 weeks continuously, and blood samples were collected under anesthesia on the last day, and extensor digitorum longus (hereinafter referred to as EDL) and soleus muscle (hereinafter referred to as Soleus) specimens were prepared, and micrographs were taken. It was photographed and the diameter of the muscle was measured. As a staining method, in addition to hematoxylin-eosin staining (abbreviated as HE in the following Table 1), rutin-ATPase staining specific to type II fibers (abbreviated as Type II in the following table 1) was performed, and the diameter of only type II fibers was also measured. It was measured. The IGF-1 used in this test was obtained by the method described in JP-A-61-1396 and is the same as human IGF-1.
