KAKENHI (Grants-in-Aid for Scientific Research) 1

  1. 海綿静脈洞部硬膜動静脈瘻と下垂体ホルモンとの因果関係に関する研究

    Grant number:18K16580  2018.4 - 2021.3

    若手研究

    西堀 正洋

      More details

    Authorship:Principal investigator  Grant type:Competitive

    Grant amount:\1950000 ( Direct Cost: \1500000 、 Indirect Cost:\450000 )

    硬膜動静脈瘻は後天的に生じる稀な頭蓋内シャント疾患である。発生部位は頭蓋内の種々の部位があるが、日本における全国調査の結果より、海綿静脈洞部は他の部位に比して2倍以上男性より女性に多い。症状は多彩であり、また診断や治療においては非常に専門的な知識と経験を必要とする疾患である。
    硬膜動静脈瘻の原因は未だに不明であるが、外傷・骨折・炎症・静脈高血圧など多くの複合的因子が関与する。海綿静脈洞部は脳下垂体に接している静脈洞であり、ここを経由して下垂体ホルモンが血中に分泌されているため、性差を考慮すると、同部位には少なからず性ホルモンの影響があると推察される。
    その関連を明確に示唆する研究や論文は極めて少ない。
    そのため、この部位における発生要因としての下垂体ホルモンやその周辺因子につき評価および研究を行う。また本研究は実際に多くの硬膜動静脈瘻について治療を行っている施設でなければ成立しづらく、当施設は本疾患において基幹病院であるため研究を進めることができる。
    性ホルモンとその代謝因子、関連する遺伝子多型(CYP19A1,HSD17B2)、生活背景の因子(飲酒・喫煙・妊娠分娩歴など)なども合わせて調査する。現在は本学生命倫理委員会へ申請を行うと同時に、機器部門と相談し、性ホルモンの測定についてELISA法を用いて解析を勧めている。同意いただいた症例より血液サンプルを採取し、検体がほぼ揃った。
    現在は解析を随時進めている。
    海綿静脈洞部・横静脈洞部の硬膜動静脈瘻の症例に対して現在までに多くの血液サンプルを得て、ELISA法を中心に解析を行っている。生活背景の因子(飲酒・喫煙・妊娠分娩歴など)なども合わせて調査している。
    海綿静脈洞部・横静脈洞部の症例から得たサンプルに対してELISA法にて解析を行っている。
    これを継続し、解析を行い論文化する予定である。
