Description
本発明は、腎臓および肝臓の状態、機能および完全性を診断または予測するための試験および装置を提供する。本発明の生物マーカー、その他の臨床化学パラメーターあるいはその組み合わせは、腎臓または肝臓の状態の診断、薬物誘発性の腎毒性または肝毒性などの有害事象の監視、腎臓または肝臓の状態を基にした薬物による治療方法の適応、または腎臓または肝臓における病気の診断またはその有病性のための臨床試験の開発のための試験法、試験または装置に変換しうる。
定義。本書で使用するとき、「腎毒性」または「腎損傷」あるいは同様に「腎障害」という用語はすべて、数多くの病気、または(限定はされないが)、敗血症I(感染)、ショック、外傷、腎臓結石、腎感染、薬物毒性、毒物または毒素、またはヨード造影剤の注射後(副作用)といった急性腎毒性の障害過程、ならびに長期にわたる高血圧、糖尿病、うっ血性心不全、狼蒼、または鎌状赤血球貧血といった慢性腎毒性の障害過程により引き起こされうる、急激であるか(急性)あるいはゆっくりとした時間をかけて低下するか(慢性)のいずれかの、腎臓の不全または機能障害を意味するものとする。どちらの形態の腎不全も、生命にかかわる代謝性の混乱の原因となる。
カルビンジンD-28kは、大きなEF-handファミリーのカルシウム結合タンパク質メンバーである。カルビンジンD-28kは、あらゆる綱の脊椎動物および広範な組織内に存在する。数人の研究者が、腎臓内で最大量のカルビンジンD-28kが遠位尿細管に局在化していることを示しているが、これはカルシウム吸収の部位としての遠位尿細管の役割と関連している。『Rhoten WB et al., Anat. Rec. 227:145-151』、『Borke JL et al., Am. J. Physiol.(Renal Fluid Electrolyte Physiol)257: F842-F849 26(1989)』。その上、加齢に伴うカルビンジンD-28kの発現の減少が、年齢に関連した腸および腎臓でのCa++運搬の減少に寄与している可能性があることが示されている。『Armbrecht HJ et al., Endocrinology 125: 2950-2956(1989)』。シクロスポリンA誘発によるラット腎臓のカルビンジン-D 28kタンパク質の減少は、そのmRNAの減少の結果である。『Grenet O et al., Biochem. Pharmacol. 55(7): 1131-1133(1998)』、『Grenet O et al., Biochem. Pharmacol. 59(3): 267-272(2000)』。
本発明は、本出願で説明した特定の実施態様という点で制限されることはなく、これは発明の個別の様相についての一つの例証として意図される。本発明には、当業者にとって明らかなとおり、その精神および範囲から逸脱することなく、数多くの修正および変化を加えることができる。本書に列挙したものに加え、本発明の範囲内の機能的に同等な方法および装置は、上記記載から当業者にとって明らかである。こうした修正および変形は、添付した請求項の範囲内に含まれることが意図される。発明は添付した請求項の条件と、そうした請求項によって権利が付与される同等物の範囲全体とによってのみ制限される。
Claims (3)
- 腎毒性を引き起こす疑いのある化合物投与後の個体における腎毒性を評価する方法であって、その腎毒性が、個体からの試料中のβ−2−ミクログロブリンの測定と、この測定されたβ−2−ミクログロブリンの量と健常な個体での対応する量との比較によって特定され、腎毒性が糸球体変質または損傷である、方法。
- 個体における腎毒性を評価する方法であって、その腎毒性が、個体からの尿サンプル中のβ−2−ミクログロブリンタンパク質の測定と、この測定されたβ−2−ミクログロブリンタンパク質と健常な個体での対応する量との比較によって特定され、腎毒性が糸球体変質または損傷である、方法。
- 被験者の薬剤による腎毒性に対する処置の効果を監視する方法であって、ここで該腎毒性が糸球体変質または損傷である、以下の工程を含む方法:
(i)薬剤の投与前に被験者から得た1以上の投与前尿試料におけるβ−2−ミクログロブリンの発現レベルを検出する、
(ii)被験者から得た1以上の投与後尿試料におけるβ−2−ミクログロブリンの発現レベルを検出する、および
(iii)投与前試料でのβ−2−ミクログロブリンの発現レベルを投与後試料でのβ−2−ミクログロブリン発現レベルと比較する。
