    本研究では日本人において加齢性難聴の発症および重症化に関連した遺伝的素因を
    明らかにするとともに、後天的要因の影響の度合いを明らかにし、難聴進行予防対策や早期
    発見へ向けた施策の元となるデータを示したい。
    シスプラチン同時併用放射線治療による難聴発症および重症化に関連する遺伝的素因および後天的因子をGWASによる解析により明らかにしたい。
    加齢性難聴に対する発症予防・早期発見・早期介入の重要性が近年注目を集めているが、発症および重症化の要因に関しての検討は十分にされておらず、対策が進まない一つの原因となっている。そこで本研究においては65歳以上の高齢者を対象に、ゲノムワイド関連解析(GWAS)を用いて遺伝的素因を明らかにするとともに後天的要因に関する詳細な調査を合わせて行い、遺伝的素因と後天的要因がどのように加齢性難聴の発症および進行に関係するのかということを明らかにしたい。
    また、耳毒性薬剤、特にプラチナ系抗がん剤の使用による難聴は不可逆であり、発症した場合治療終了後の生活の質が著明に低下する。そこで研究代表者である和佐野が聴覚評価事務局として参加している頭頸部がんに対するシスプラチン併用化学放射線療法に関する臨床試験(JCOG1912試験)の附随研究として、加齢性難聴と同様のプロトコルを用いて検討を行い、プラチナ系抗がん剤の使用による難聴発症および重症化のリスクを明らかにしたい。さらに上記の結果をもとに、今後の大規模試験に向けて低コストで多数のリスク評価を行うことのできるカスタムアレイを開発する。
    本年度はシスプラチン難聴コホートに対する遺伝子解析に向けたJCOG内での承認手続きおよびバイオバンク構築のための手続きを行うとともに、加齢性難聴コホートに関する遺伝子解析に向けた研究体制整備ならびに倫理委員会手続きを進めている。
    遺伝子解析を含むことから倫理委員会手続きに時間を要するため、若干遅れている。
    倫理委員会手続きをできるだけ早期に終了し組み入れの開始を目指す。

    オーストラリアで開発された難聴者に対するグループリハビリテーション(ACEプログラム)が鬱や不安、社会的孤立などの精神的社会的影響が有意に改善したと報告される。現在日本語翻訳されておらず、日本における有効性は検討されていない。本研究では当院補聴器外来に通院する難聴者を対象にACEプログラムを行い、その参加前後での精神的社会的影響を評価し日本における有効性を示したい。
    本研究の最終目的は、難聴者に対するACE(Active Communication Education)プログラム日本語版の有効性を立証することである。ACEプログラムはオーストラリアで開発されたグループ介入プログラムであり、補聴器を装用していない、あるいは装用に満足していない難聴者を対象としている。難聴によって引き起こされる劣等感、社会的孤立、対人関係の困難、活動意欲の低下といった心理的・社会的側面に対して、海外の研究では本プログラムの導入により有意な改善が見られており、その効果が報告されている。日本においては、難聴者に対する介入は主に補聴器の装用に限られており、それ以外の選択肢は乏しいのが現状である。本プログラムが日本でも有効性を示すことができれば、補聴器に加えた新たな治療的支援の選択肢として臨床的意義は大きいと考えられる。本年度は、研究実施計画に基づき、まずACEプログラム原本の日本語版の作成に着手した。翻訳作業においては、単なる言語の置き換えではなく、日本の文化的あるいは社会的背景、対象である難聴者の特性を十分に考慮しながら内容の調整を行い、日本国内の難聴者にとって理解しやすく、かつ実施可能な形へとプログラムを適応させた。完成した日本語版ACEプログラムについては、第9回耳鳴・難聴研究会および第69回日本聴覚医学会総会・学術講演会にて発表を行い、臨床現場に携わる専門家からの意見や助言を受けたことで、さらなる改善や精査を実施する契機となった。また、次年度に実施を予定している介入試験に向けて、各研究分担者および協力機関との間での情報共有や調整を行い、研究体制の整備を進めた。さらに、臨床研究を円滑に開始するために、中央倫理審査委員会への申請書類の作成を行っており、承認が得られ次第、ACEプログラム日本語版を用いた本格的な臨床研究を開始する予定である。
    当初立案した年間スケジュールに概ね沿っており適切に管理されている。定期的な進捗確認とタスク管理により計画通りに作業を進めており、遅延や大きな障害は生じていない。以上のことから、本年度の研究は計画通りに推移しており、全体としておおむね順調に経過していると評価できる。
    上半期に中央倫理審査の承認を得た後、各研究分担者および研究協力者の所属する医療機関において、ACEプログラム日本語版を用いた臨床研究を円滑に実施できるよう、研究体制の確認と調整を引き続き行う。評価には主に質問紙法を用い、介入前・介入後での変化を経時的に収集・分析することで、介入の有効性を多角的に検討する。あわせて、実施手順の標準化とデータ管理体制の整備を進め、信頼性と再現性の高い研究結果が得られるよう、関係機関との連携を強化しつつ、計画に基づいた着実な研究遂行を図る。

    一側性難聴者は、騒音下や多人数での会話において聞き取りが不自由であるにも関わらず、本邦では医療、教育、社会的支援に目が向けられてこなかった。令和2年度の日本医療研究開発機構(AMED)岩崎班の研究において、一側性難聴者の障害の現状とその対応方法に関する研究が行われた。その結果、雑音下語音検査では、検査結果に個人差が多く、医学的介入(補聴器、人工内耳等)の適応評価のための検査条件をさらに詳細に検討する必要があることがわかった。本研究の目的は、雑音下語音検査の検査条件を確立することであり、多機関共同研究とすることでより多くのデータを収集・分析し、雑音下語音検査の標準化を目指す。
    本研究の主たる目的は、一側性難聴者における雑音下語音検査の検査条件を探ることである。一側性難聴の場合、両耳聴にて得られる効果(両耳加重効果、両耳スケルチ効果、頭部陰影効果)が希薄化するため、それらを評価するために3つの条件下で検査を実施した。
    本研究は10施設による前向き観察研究であり、目標症例数を患者群100例、正常群70例としていたが、今年度に結果が得られた症例は患者群12例、正常群35例であった。
    一側性難聴の場合、静寂下では正面および健聴側からの音声提示において成績に影響がないものの、難聴側から音声が提示された場合は、静寂下であっても語音聴取に影響を与えることが分かった。また、雑音が付加された状況下では、静寂下で影響のなかった正面および健聴側からの音声提示においても成績が悪化した。そして、クロス補聴器を装用した場合は若干の改善傾向が見受けられるものの有意差をもった語音聴取の改善とまでは至らなかった。さらに、難聴側の音刺激を健聴側へ送信するというクロス補聴器の特性からかえって成績を悪化させる要素も見受けられた。以上の所見は単音節と単語の両者で同じように示された。

    We investigated the efficacy of sound stimulation of 100 Hz for treating vestibular dysfunction in patients with Meniere’s disease (MD). Patients with definitive MD with intractable vestibular symptoms and endolymphatic hydrops (EH) in the inner ear were evaluated. The experimental group received sound stimulation of 75 dB at a frequency of 100 Hz for 5 min, and the control group received sound stimulation of 75 dB at a frequency of 250 Hz for 5 min. Cervical vestibular-evoked myogenic potentials (cVEMPs) were measured before and after each sound stimulation, and the results of the clinical tests were compared between the two patient groups. Significant increases in cVEMP amplitudes were observed after sound stimulation of 100 Hz in ears with vestibular endolymphatic hydrops, although no such improvement was observed in the control group.

    In a comparison of bilateral and unilateral implantation in sequential bilateral cochlear implant surgery cases more than 6 months after implantation, SRT was better in bilateral implantation, but the first side tended to be slightly better. However, in the interactive spatial listening test, there was no difference in the direction of the noise. However, in the interactive spatial listening test, binaural hearing aid users showed better discrimination of the minimum angle. Additive and squelch effects due to binaural use were observed, but limited effects were suggested for SRM. This is a new finding that the effect of noise on hearing is important, and that an environment in which the effect of noise on the good hearing ear is minimal is better.

    The results of ABR in R702C-Atoth1 mice revealed that some mice caused hearing loss and others did not. Three out of 46 mice showed 70 dB or more in all frequency ranges. Immunostaining was performed using NMMHC-IIA (MYH9). A negative control was prepared. The expression site of the NMMHC-IIA in the inner ear was compared in three individuals in one wild-type gene expression and two expressing the deafness in the R702C-Atoth1 mice. As shown in FIGS. 2 and 3, the expression was almost the same as that of the wild type, and there was no difference between individuals. No morphological changes were observed on light microscopy and immunostaining. Since only a very small amount of the inner ear tissue sample can be obtained, the amount was insufficient to confirm that the MYH R702C gene was contained in the inner ear in a tissue-specific manner. In the future, we will focus on the morphological change of sensory hair, which is a finer structure, and study it repeatedly.
