メタボリック症候群を基盤とする非虚血性慢性心不全の病態解明と疾患概念の確立

Research Project

Project/Area Number 24591055
Research Category

Grant-in-Aid for Scientific Research (C)

Research InstitutionHiroshima University

Principal Investigator

木原 康樹  広島大学, 医歯薬保健学研究院(医), 教授 (40214853)

Project Period (FY) 2012-04-01 – 2015-03-31
Keywordsメタボリック症候群 / 心筋障害 / 心不全 / ミトコンドリア
Research Abstract

メタボリック症候群(内臓肥満)に合併したうっ血性心不全患者の入院が増加しており、65歳以下男性では心不全入院全体の7割近くを占めている。それら患者の2/3は虚血性心不全であるが残りの1/3は非虚血性であり、後者における心筋傷害の原因は不明である。本研究はメタボリック症候群に合併する非虚血性心不全の本態が、「脂質過剰に起因する心筋ミトコンドリア代謝異常である」との仮説をSPECTやMRSを用いて臨床的に検討するとともに、経カテーテル的に得た心筋生検標本における遺伝子発現と免疫組織学的検索により直接の証明を試み、新たな疾患概念としての「メタボリック心筋症」を検証する。
65歳以下の男性でうっ血性心不全のため初回入院した患者を対象とする。冠動脈造影検査にて冠動脈疾患が否定された者をメタボリック症候群(日本動脈硬化学会等による診断基準2005年に拠る)の有無により、メタボリック群と非メタボリック群に分類する。臨床検査として123I-MIBG心筋SPECTによる脂肪酸代謝、MR Spectroscopyによる心筋脂肪酸代謝、心臓エコー検査による左室形態の定量的評価、心臓カテーテル検査による血行動態評価と心内膜下心筋生検を施行する。次いで心筋生検標本を用いた組織学的・分子生物学的検討を行い、ミトコンドリアのマスタースイッチであるERR-α/PCG-1シグナルを受けてMitDNA転写を直接制御していることを示し、Endonucrease Gの異常活性化を証明する。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

対象患者をリクルートするため広島市内7基幹病院(広島市立安佐市民病院 土手慶五循環器内科主任部長、広島市立広島市民病院 井上一郎循環器内科主任部長、広島赤十字・原爆病院 岡田武規則循環器内科部長、あかね会土谷総合病院 塩出宣雄環器内科部長、JA広島総合病院 藤井隆循環器内科部長、県立広島病院 上田浩徳環器内科部長、広島鉄道病院 寺川宏樹循環器内科部長)が研究協力者として参画している。研究に同意の得られた患者は広島大学病院循環器内科に転院し、インフォームドコンセントと文書による同意を確認の後検討を行う。各群20名を目標としており、対象患者の臨床検査が目下順調に進行している。

Strategy for Future Research Activity

対象症例20例の目標を達成し、その臨床評価・循環器的検索パラメターを明確にする。対象から得た心筋生検標本を用いて、免疫染色、電子顕微鏡的形態把握、PCRによる遺伝子発現状態の定量化を進める。

Expenditure Plans for the Next FY Research Funding

平成24年度は対象患者の検索とその臨床諸指標の収集が主たる実施内容であった。実臨床のなかで保健償還される検査については本研究費用からの出費が不要であったために予定額を下回る収支となった。一方、次年度においては患者から得た血液解析や心筋生研標本への遺伝子学的、免疫学的検索が本格化するため、本年度執行を猶予した費用も含めて消費することが見込まれる。次年度と次々年度においてはそれら解析を精力的に実施し、次々年度においては成果を内外に公表する。
