副甲状腺機能障害

Hypoparathyroidism

副甲状腺機能異常の中で機能低下症について，その原因と病態，病態生理からみた治療管理の概略を述べた．副甲状腺機能低下症は様々な原因で発症し，その鑑別は治療方針の決定に重要である．また，治療においては欠落ホルモンを補充することは難しく低Ca血症を活性型ビタミンDの投与で補正しているだけであるため，高Ca尿症の発症に注意する必要がある．

This section described the pathophysiology of hypoparathyroidism and practical ways to diagnosis and manage it.　The etiology of hypoparathyroidism varies widely but precise diagnosis of its pathophysiology is important because of the possible important influence on its prognosis.　Moreover, it is important to know that the purpose of the active vitamin D treatment of hypoparathyroidism is not to keep serum calcium within the normocalcemic range but to control serum calcium for the prevention of hypocalcemic symptoms.
