    Background: A recent conditional recommendation suggests considering live-attenuated vaccines for solid organ transplant recipients, yet the conditions of their safe and effective administration remain unclear. Methods: This prospective study was conducted at Keio University Hospital from 2002 to August 2023. We gave a live-attenuated vaccine to liver transplant (LT) recipients fulfilling criteria for live-attenuated vaccines, including criteria for humoral and cell-mediated immunity. Patient background information, immunization date, vaccine strain, immunosuppressive agents at the time of vaccination, and antibody titers were collected. Factors related to primary and secondary vaccine failure were evaluated to enhance the effectiveness of the live-attenuated vaccine program after LT. Results: Among 67 LT recipients, 54, 55, 47, and 55 received at least one dose of live-attenuated vaccine for measles, rubella, varicella, and mumps, respectively. The difference in vaccine strains, but not the use of two or more immunosuppressive agents, was associated with a lower risk of vaccine failures. Measles vaccine with the AIK-C strain exhibited significantly lower primary and secondary failure rates than the CAM-70 strain (1/38 vs. 4/16, odds ratio: 0.08, 95 % confidence interval [CI]: 0.01–0.80, p = 0.02, and hazard ratio: 0.54, 95 % CI: 0.34–0.85, p = 0.01, respectively). No primary failures were observed with the TO-336 strain of rubella, whereas 4 of 10 LT recipients with the Matsuura strain of rubella did not seroconvert. For mumps, the Hoshino strain showed lower primary failure rates than the Torii strain (15/52 vs. 3/3, p = 0.03). Conclusion: According to a 20-year long-term study, vaccine strains are the most critical factor influencing primary and secondary vaccine failure in post-transplant live-attenuated vaccination.

     View Summary

    炎症性腸疾患患者から分離されたクレブシエラを無菌マウスに定着させ、クレブシエラ単独定着マウスを作成した。そのマウスの胃内に5人の健康ボランティアか らの糞便を投与した。いずれの便投与でもクレブシエラの菌量は著明に低下し、健常者の腸内細菌の中にはクレブシエラを排除する菌が存在することが示唆され た。 この5つの糞便サンプルのうち、3種類の便(サンプル#F、I、K)から菌を嫌気性下で培養した。F便から単離した37菌株クレブシエラ単独定着マウスに投与す ると、F便由来の37菌株は便と同程度のクレブシエラの菌量の低下が見られ た。単離したF便由来の37菌株にはクレブシエラを腸管から排除する菌が含まれていると考えられた。 F便由来の37株を投与したクレブシエラ単独定着マウスに、抗生剤(アンピシリン)を飲水投与したところ、クレブシエラの菌量は一時的な増加が見られたがその後減少した。この間の37種類の菌の菌量の推移をqPCRで確認した。アンピシリン投与で消失した株やクレブシエラの動きと無関係に動く菌を除外し18株を選び出した。この18種類の菌をクレブシエラ単独定着マウスに投与してもクレブシエラ排除効果が見られた。また、この18株は他の抗菌薬耐性クレブシエラやESBL産生大腸菌に対しても排除効果がみられた。さらに、炎症性腸疾患モデルマウスであるIL10KOマウスにクレブシエラを定着させ、18株を投与するとクレブシエラの菌量の低下とともに炎症の改善が認められた。F便から単離した菌株セットにはクレブシエラを腸管から排除する能力が備わっており、これらをプロバイオティクスとして使用することで耐性菌や炎症性腸疾患の新たな治療薬となり得る可能性が期待できる。
