    Expanding tandem gene arrays facilitates adaptation through dosage effects and gene family formation via sequence diversification. However, experimental induction of such expansions remains challenging. Here, we introduce a method termed break-induced replication (BIR)-mediated tandem repeat expansion (BITREx) to address this challenge. BITREx places Cas9 nickase adjacent to a tandem gene array to break the replication fork that has just replicated the array, forming a single-ended double-strand break. This break is subsequently end-resected to become single stranded. Since there is no repeat unit downstream of the break, the single-stranded DNA often invades an upstream unit to initiate ectopic BIR, resulting in array expansion. BITREx has successfully expanded gene arrays in budding yeast, with the CUP1 array reaching ∼1 Mb. Furthermore, appropriate splint DNAs allow BITREx to generate tandem arrays de novo from single-copy genes. We have also demonstrated BITREx in mammalian cells. Therefore, BITREx will find various unique applications in genome engineering.

    Macrophage activation syndrome (MAS) is an autoinflammatory condition, which severely complicates autoimmune diseases, such as systemic juvenile idiopathic arthritis, adult onset Still’s disease, and systemic lupus erythematosus. MEFV gene encodes a component of pyrin inflammasome, whose variants cause familial Mediterranean fever (FMF). We experienced a recurrent MAS case with homozygous MEFV P369S variants accompanied by Sjögren syndrome and pulmonary arterial hypertension, whose recurrent MAS was successfully treated with canakinumab. Pathogenicity of MEFV P369S variant is still inconsistent, and clinical interpretation of this variant is challenging. Thus, we reviewed previous literatures and revealed that the majority of FMF patients with collagen diseases in carried MEFV P369S variant, all of which were reported from Japan. In this case-based review, we clarify the epidemiology of MEFV variants in collagen diseases and discuss the significance of their genetic analysis.

    日本の多施設前向きレジストリであるKyushu Collagen Disease Network for Systemic Lupus Erythematosus(KCDN-SLE)のデータを用いて、全身性エリテマトーデス(SLE)患者の臨床的特徴、薬剤開始の目的、他の候補薬剤、短期の有効性と安全性を評価した。2022年8月~2023年11月にKCDN-SLEに登録された、治療歴のあるSLE患者69例(平均43.7±15.2歳、女性62例)を対象とした。維持期に投与された薬剤はヒドロキシクロロキン(HCQ)(12例)、生物学的製剤(41例)、免疫抑制剤(16例)であり、19例が他剤に切り替えていた。併用しているプレドニゾロンの用量は中央値7.5mgであった。活動性の臓器病変を有する患者ではHCQと生物学的製剤が広く使われていた。活動性患者48例のうち22例が低疾患活動状態になったが、生物学的製剤の投与開始との関連は明らかではなかった。

    関節リウマチ(RA)診療ガイドラインの改訂に際し、本改訂に携わる作業部会に対してRA療法における疾患修飾性抗リウマチ薬(DMARDs)の有効性と安全性に関する最新のエビデンスを提示するため、システマティックレビューを行った。各種文献データベースを用いて、2022年6月までに発表されたRAに関する無作為化比較試験を検索した。作成した15のクリニカルクエスチョン(CQ)について、2名のレビュアーが論文をスクリーニングし、主要なアウトカムを評価し、メタアナリシスを実施した。15のCQのうち、1つはメトトレキサート(MTX)、1つはオゾラリズマブ(OZR)、5つはリツキシマブ(RTX)、6つはJanusキナーゼ阻害剤(JAKi)、5つはバイオシミラー(BS)に関するCQであった。MTX皮下投与は、MTX未投与のRA患者において経口MTXと同等の有効性を示している。OZRは、従来のcsDMARDへの反応な不十分なRAにおいて患者においてプラセボよりも有効であることが示されている。RTXは、csDMARDの併用の有無にかかわらず、bDMARDへの反応が不十分なRA患者において、他のbDMARDと同等の有効性を示している。JAKiとMTXの併用は、MTX抵抗性RA患者において、4年間にわたって腫瘍壊死因子阻害薬と同等の臨床反応と安全性を示した。BSは、csDMARD抵抗性およびbDMARD抵抗性RA患者において、オリジナルのbDMARDと同等の有効性を示している。

    Objectives: To evaluate the long-term impact of immunosuppressive therapeutic agents on antibody response to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) mRNA vaccination in patients with autoimmune rheumatic diseases (AIRD) in order to propose a strategy for annual vaccination. Methods: This prospective multicentre cohort study evaluated the humoral response to second and third BNT162b2 and/or mRNA-1273 vaccines in 382 Japanese AIRD patients classified into 12 different medication groups and in 326 healthy controls (HCs). The third vaccination was administered six months after the second vaccination. Antibody titres were measured using the Elecsys Anti-SARS-CoV-2 S assay. Results: The seroconversion rate and antibody titres were lower in AIRD patients than in HCs 3–6 weeks after the second vaccination and 3–6 weeks after the third vaccination. Seroconversion rates were <90% after the third vaccination in patients receiving mycophenolate mofetil and rituximab. Antibody levels after the third vaccination were significantly lower in the groups prescribed TNF inhibitor with or without methotrexate, abatacept and rituximab or cyclophosphamide than those of HCs in a multivariate analysis adjusting for age, sex, and glucocorticoid dosage. The third vaccination induced an adequate humoral response in patients treated with sulfasalazine, bucillamine, methotrexate monotherapy, iguratimod, interleukin-6 inhibitors or calcineurin inhibitors including tacrolimus. Conclusions: Repeated vaccinations in many immunosuppressed patients produced antibody responses similar to those observed in HCs. In contrast, annual vaccination in patients receiving TNF inhibitors, abatacept, mycophenolate mofetil and rituximab may require caution.
