Outline of Annual Research Achievements

発展途上国では、ピロリ菌感染者すべてに除菌療法を行う経済力もなければ十分な内視鏡設備や内視鏡医も存在しない。ピロリ菌培養ができる施設も稀で、効果的な除菌療法も存在しない。そこで本研究では、アジアの発展途上国で胃癌多発国であるモンゴル、ブータン、ベトナムに焦点を当て、現地共同研究者と共同で、除菌を行うべき人および除菌法の選択に有用な未知の病原因子および薬剤耐性関連遺伝子の変異・多型の検索を、次世代シーケンサーを用いた菌側のゲノムワイド関連解析によって行う計画を立てた。最終的には、新規遺伝子解読技術(ナノポア)による、従来の内視鏡検査および細菌培養を必要としない迅速かつ非侵襲な病原因子および薬剤耐性関連遺伝子検出方法の開発に取り組むこととした。ブータンに関しては、地球規模課題対応国際科学技術協力プログラム(医療分野国際科学技術共同研究開発推進事業)(SATREPS) および 地球規模保健課題解決推進のための研究事業 (GACD)に採択され、これらの資金の活用も可能であったため、本研究では、東南アジア各国、さらにはアフリカ(コンゴ民主共和国)のピロリ菌解析に手を広げることも可能となり、各国での薬剤耐性関連遺伝子変異を検討することができ、またコンゴ民主共和国のピロリ菌には従来では稀なアモキシシリン耐性が多くみられること、さらにその原因となる遺伝子変異に関しても4か所の変異が関与していることを見出し、現在論文投稿中である。新型コロナウイルス感染禍も落ち着き、本年度は成果を海外で発表する機会も得た。米国消化器病週間(DDW)では、モンゴルからの留学生が口演発表、またアジア太平洋消化器病週間(APDW)では、代表者の山岡がマーシャル・ワレン賞を受賞(国内4名目)、インドネシアからの留学生が若手研究者賞(YIA)で1等賞、モンゴルからの留学生もYIA最終選考6名に選ばれた。
