Abstract
Description
I. 臨床の目的
トリメタジジンが肝不全患者の肝機能を改善できるか否かを評価する。
1. 臨床方法
臨床試験方法として、シングルセンターコホート研究を採用した。
関連する参考文献および前回の結果に基づいて、症例数は50以上でなければならない。フォローアップの損失数とドロップアウト(10%程度に抑える)を考慮すると、60件(臨床群30例、コントロール群30例)の選択される必要がある。現在、鄭州大学の第一附属病院は、58例の臨床観察を完了している。
2014年8月19日から2014年12月19日の間に登録された全ての重篤な肝炎患者をコントロール群に入れた; 12月9日から申請日までの間に登録されたすべての人を臨床群に入れた。
1. 選択基準
心筋損傷により複雑化された肝不全と診断された患者(中国医師会およびCMAの肝疾患学会の感染症学会によって公布された「肝障害の診断と治療ガイド」2012年版に規定されている診断基準: 肝性脳症に罹患している; 非常に弱く、重大な消化管症状を伴う; 黄疸は急速に深まり、血清TBILは正常な上限値の10倍高い、または>17.1umol/lで増加する; 他の原因を除いてPTA<40%またはINR>1.5である; 腹水代償不全を伴う);
年齢: 18〜70;
男性または女性;
入院患者;
インフォームドコンセントに署名し、良好なコンプライアンスを持つ患者。
18歳以下または70歳以上の患者;
ショックリバー(Shock liver)(虚血性肝炎)(虚血性肝疾患)と診断された患者;
妊娠中の肝不全またはHELLP症候群を有する患者;
肝臓の悪性腫瘍を派生する肝不全を有する患者;
難治の低血圧を有する患者;
敗血症性ショックを有する患者;
肝臓移植を受けようとしている(約8時間以内)患者;
トリメタジジン薬に対してアレルギー性を持つ患者;
トリメタジジン薬に対して耐性を持つ患者;
薬物および/またはアルコールの乱用者;
妊娠中または授乳中の女性;
最近(半年以内)に心筋梗塞を有する患者;
深刻な腎不全の患者。
選択基準に適合しない場合又は事例報告に不適合記録がある場合;
悪影響や乏しい効果のためではなく、臨床から脱落する場合。
4. 患者の脱落基準
研究者は、医学的観点から被験者との臨床を中止する必要があると考慮する;
患者が、臨床を中止するよう要求する;
深刻な有害事象の発生。
1. 臨床群:トリメタジジン(TMZ):Servier(Tianjin)Pharmaceutical Co. Ltd.製の20mg /錠剤。使用法と用量:毎回1錠、1日3回、経口投与、4週間の治療コース。
2. コントロール群:Dandong Yichuang Pharmaceutical Co.、Ltdによって提供されたこの臨床におけるコントロール群のためのジイソプロピルアミンジクロロアセテート(DCA)(80mg/D)、4週間の治療コース。
3. 基本的な治療:入院の際に、L-オルニチン-L-アスパラギン酸(LOLA)、還元型グルタチオン、イソグリチルリチン酸マグネシウムおよびヒト血清アルブミンの投与を含む。HBV関連肝不全患者もラミブジンで治療した。
1. ロシュ・ダイアグノスティックス(上海)Ltd.が提供する製品を用いて、クロマトグラフィーにより試験したアラニンアミノトランスフェラーゼ(ALT)。
2. ロシュ・ダイアグノスティックス(上海)Ltd.が提供する製品を用いて、クロマトグラフィーにより試験したアスパラギン酸トランスアミナーゼ(AST)
。
1. 肝機能の維持
a. 5日間の治療後、ALTとASTの比較は肝不全で減少し、関連する数学的モデル分析は、TMZ群(k=259.4)のALT減少が、DCAコントロール群(k=67.325)のALT減少よりもはるかに大きいことを示した; TMZ群のAST低下(k=362.53)もDCAコントロール群(k=142.77)よりもはるかに大きかった。これは、TMZがトランスアミナーゼを短時間でより低レベルに減少させ、それによって肝細胞傷害を減少させることができることを示している。図2参照。
一般的な有害反応事象:現在のところ、両方の群は安全であり、有害事象はわずかで、重大な有害事象はない。
3. 腎機能障害:腎機能検査の結果は、2つの群の間に統計的差異を示さなかった。
結論:トリメタジジンは、短期間でALTおよびASTレベルを低下させることができ、より高いALTおよびASTレベルを効率的に低減し、特にASTレベルを有意に低下させる。故に、TMAは、DCAと比較して、肝機能を補修し、毒性および副作用を低下させる能力が高い。
事例1: Ms. Lu、女性、50歳、20年以上前からHBsAg陽性、肝機能の再検査を複数回受け、すべてのカラー超音波検査の結果が正常範囲内であったため、特別な治療を受けていない。3か月前、寒さと過労を覚えた後、彼女は腹部膨満と黄色の尿を発症し、6日以上の病状の悪化の後に入院した。入院時に、彼女は、大規模な腹水と全身の皮膚と粘膜に深刻なキサントクロミー(黄色化)、激しい吐き気、食欲不振および倦怠感を併発した。入院後の検査では、ALT270u/L、AST303u/L、ALB(血清アルブミン)19g/Lを示した。鄭州大学付属第一医院では、併用療法に基づいて、TMZを毎日3回、毎回1錠ずつ投与した。その12日後、再検査の結果は、ALT41u/LおよびAST68u/Lを示した。彼女の腹水は減少し、エネルギーと食欲が著しく改善した。10日以上の強化療法の後、彼女は病院から退院し、その後、彼女は4週間薬を服用し続け、肝臓の酵素は完全に正常に戻り、衰弱または食欲不振を感じなかった。
Claims (4)
- 肝疾患の予防および治療における肝保護薬としての新たな用途を特徴とするトリメタジジン。
- トリメタジジンが、休止Tリンパ球の活性化リンパ球への活性化を阻害し、サイトカインの放出を減少させ、免疫系によって引き起こされる肝細胞傷害を減少させ; 肝細胞における脂肪酸代謝を阻害し、肝細胞におけるエネルギー代謝過程を最適化させ; ミトコンドリア透過性移行細孔の正常な機能を維持し、肝細胞アポトーシスを減少させることが可能であることを特徴とする、請求項1に記載の肝保護剤としてのトリメタジジンの新規使用。
- 肝保護作用において、肝保護薬物としてのトリメタジジンは、脂肪酸代謝を阻害することができ、特にミトコンドリアケトアシルチオラーゼ活性を阻害し、それにより細胞脂肪酸β酸化を阻害し、ROS反応を減少させ; ここで、トリメタジジンは、ミトコンドリアピルビン酸デヒドロゲナーゼ活性を増強することができ、それにより、虚血細胞において、エネルギーを得るためにβ酸化よりも低い酸素消費が低いグルコースの好気的酸化を促進することができ、および肝細胞におけるエネルギープロセスを最適化することができ、それによって虚血の間、適切なエネルギー代謝を維持することを特徴とする、請求項1に記載の肝保護剤としてのトリメタジジンの新規使用。
- 肝保護薬としてのトリメタジジンが、主に以下の3つの特徴を介して達成される、請求項1に記載の肝保護薬としてのトリメタジジン:
(1) リンパ球の活性化は脂肪酸代謝により提供されるATPを必要とするため、トリメタジジンはFFA代謝を阻害し、休止Tリンパ球の活性化リンパ球への活性化を阻害し、それにより、活性化された細胞傷害性Tリンパ球によるサイトカインの放出を減少させ、外因性細胞壊死またはアポトーシスを減少させ、およびヒト免疫系によって引き起こされる肝細胞障害を減少させ;
(2) 肝不全時の肝細胞が高アンモニア、低酸素、高ビリルビンの有害環境下にあり、ATPの細胞生成に深刻な影響を及ぼし、肝細胞の発達および成長を阻害するので、トリメタジジンは肝細胞における脂肪酸代謝を阻害し、グルコース解糖およびその後のTCA(トリカルボン酸サイクル)サイクルを促進し、同じ量のATPを生成するのに必要な酸素原子を減少させ、RNA、DNAおよびタンパク質を含む活性物質を合成するために肝細胞が必要とするATPを与えることでグルコースを酸化するために限られた酸素原子の使用を促進することができ; ここで、肝臓損傷、特に肝不全の間に、損傷した肝臓における微小血栓の形成が肝細胞の低酸素状態につながることは一般的であり; ここで、トリメタジジンはまた、FFA(遊離脂肪酸)代謝を阻害し、肝細胞におけるROSの形成を減少させ、二次肝細胞傷害を減少させることができ;
(3) ミトコンドリア損傷に起因する肝細胞障害がミトコンドリアを損傷させるため、MPTの開口およびK+およびCa2+の流出を特徴とすることができる、ATP合成および自然免疫を減少させ、それによって、高血中アンモニアが起因する肝細胞障害における典型的に示される内因性のアポトーシスを開始することで、トリメタジジンは、MPT細孔によるカルシウムイオンの適切な放出を維持し、肝細胞のアポトーシスを減少させることができる。
