[0002] 関節リウマチでは、免疫異常や感染症が原因となって、滑膜に炎症性細胞が浸潤 し、さらに、血管新生に伴って滑膜線維芽細胞の増殖が亢進して、パンヌスと呼ばれ る炎症性滑膜肉芽組織が形成される。パンヌスが形成されると、骨や軟骨の破壊が 進み、関節に不可逆的な障害がもたらされる。  [0002] In rheumatoid arthritis, inflammatory cells infiltrate into the synovium due to immune abnormalities and infections, and the proliferation of synovial fibroblasts increases with angiogenesis, which is called pannus Inflammatory synovial granulation tissue is formed. When pannus is formed, bone and cartilage are destroyed, resulting in irreversible damage to the joint.
変形性関節症は、加齢や機械的ストレスが原因となって、関節軟骨表面の崩壊と、 これに伴う関節辺縁の新たな軟骨の増殖、関節の変形、関節の軟骨の遅行変性が おこり、しばしば痛みと機能喪失とを伴うことを特徴とする単関節炎疾患である (ァメリ カン'ファミリ^ ~ ·フイジシャン(Am. Fam.

Rheumatoid arthritis and osteoarthritis have many similarities in the mechanism of articular cartilage destruction. Synovial synovial fluid and synovial membranes are produced and secreted by many kinds of matrix meta-oral proteases in joints such as 'soft bone', which breaks down the extracellular matrix, which contributes to joint destruction (CELLS 'Tissues Organs, 174 (1-2) 卷, p. 34 (2003)). These reports suggest that suppressing the proliferation of synovial fibroblasts is effective in the treatment of rheumatoid arthritis and osteoarthritis.

[0005] 従来、関節リウマチの薬物療法には、主に関節の疼痛および炎症を軽減するため に、種々の非ステロイド性抗炎症薬、プレドニゾロンなどのステロイド剤またはメトトレ キサートをはじめとする抗リウマチ薬が使われている(治療、 78卷、 p. 3553、南山堂 (1996年))。変形性関節症では、軟骨破壊を抑制するヒアルロン酸が軟骨保護剤と して使われている(アースライティス&リューマテイズム(Arthritis Rheum. )、20卷 、p. 1461 (1993年);アースライティス&リューマテイズム(Arthritis Rheum. )、4 3卷、 p. 1905 (2000年))。全身性エリテマトーデスでは非ステロイド性抗炎症薬や プレドニゾロンなどのステロイド剤、強直性関節炎では非ステロイド性抗炎症薬ゃスル フアサラジンなどの抗リウマチ薬、乾癬症患者に合併する滑膜増殖を伴 、骨破壊に まで至る乾癬性関節炎では非ステロイド性抗炎症薬、抗リウマチ薬やステロイドの関 節内注入、椎間板の細胞外マトリックスの破壊が認められる椎間板疾患では非ステロ イド性抗炎症薬や鎮痛薬、急性結晶性滑膜炎では非ステロイド性抗炎症薬やコルヒ チンなどが治療に使われている。また、理学療法や、骨切り術、人工関節置換術など の手術療法も治療に使われている。(広畑和志ら編 リウマチ学 同文書院(1989年 );ョ一口ピアン'ジャーナノレ 'ォブ 'メディシナノレ'リサーチ(Eur. J. Med. Res. )、 20 卷、 p. 150 (2001年))。  [0005] Conventionally, pharmacotherapy for rheumatoid arthritis mainly includes anti-rheumatic drugs such as various nonsteroidal anti-inflammatory drugs, steroidal drugs such as prednisolone or methotrexate, mainly to reduce joint pain and inflammation. (Treatment, 78 卷, p. 3553, Nanzan-do (1996)). In osteoarthritis, hyaluronic acid, which inhibits cartilage destruction, is used as a cartilage protective agent (Arthritis Rheum., 20 卷, p. 1461 (1993); Earth Lights & Rheumatism (Arthritis Rheum.), 4 3), p. 1905 (2000)). In systemic lupus erythematosus, non-steroidal anti-inflammatory drugs and steroids such as prednisolone, and in ankylosing arthritis, non-steroidal anti-inflammatory drugs, anti-rheumatic drugs such as sulfasalazine, and synovial proliferation associated with psoriasis patients, bone destruction Psoriasis arthritis leading to non-steroidal anti-inflammatory drugs, intrarural injection of anti-rheumatic drugs and steroids, and intervertebral disk disease with destruction of extracellular matrix of intervertebral discs, non-steroidal anti-inflammatory drugs and analgesics, acute Non-steroidal anti-inflammatory drugs and colchicine are used for treatment of crystalline synovitis. Physiotherapy, surgical treatments such as osteotomy and artificial joint replacement are also used for treatment.
