關(guān)鍵詞：結(jié)核病、NAT2基因型、抗結(jié)核藥物、血漿濃度、肝功能

Introduction：結(jié)核病是一種常見(jiàn)的傳染病，治療包括多種抗結(jié)核藥物的聯(lián)合應(yīng)用。然而，不同患者對(duì)抗結(jié)核藥物的反應(yīng)存在差異，可能與遺傳因素和生理狀態(tài)有關(guān)。NAT2基因型是結(jié)核病患者個(gè)體代謝差異的重要原因之一，已有研究發(fā)現(xiàn)NAT2基因型與抗結(jié)核藥物代謝有關(guān)。此外，患者肝功能狀態(tài)也可能影響抗結(jié)核藥物的代謝和排泄。因此，本研究旨在探討結(jié)核病患者NAT2基因型、抗結(jié)核藥物血漿濃度及其肝功能之間的相關(guān)性。

Methods：本研究采用前瞻性隊(duì)列研究設(shè)計(jì)，選取100名確診為結(jié)核病患者為研究對(duì)象，收集其血樣和肝功能指標(biāo)數(shù)據(jù)。采用PCR技術(shù)檢測(cè)NAT2基因型，用HPLC方法檢測(cè)患者血漿中異煙肼、利福平、吡嗪酰胺和乙胺丁醇的濃度，同時(shí)分析肝功能指標(biāo)（谷丙轉(zhuǎn)氨酶、總膽紅素、血清白蛋白和血清肌酐）。

Results：本研究發(fā)現(xiàn)，NAT2*4、NAT2*6和NAT2*7基因型相對(duì)占優(yōu)勢(shì)，NAT2基因型與抗結(jié)核藥物血漿濃度存在顯著相關(guān)性；其中NAT2*4基因型患者血漿異煙肼濃度顯著高于其他基因型。此外，患者肝功能指標(biāo)與抗結(jié)核藥物血漿濃度和NAT2基因型也存在顯著相關(guān)性，肝功能異?；颊呖菇Y(jié)核藥物血漿濃度明顯高于正?；颊摺?/p>

Conclusion：本研究發(fā)現(xiàn)結(jié)核病患者的NAT2基因型、抗結(jié)核藥物血漿濃度及其肝功能之間存在關(guān)聯(lián)性，且這種關(guān)聯(lián)性可能對(duì)藥物療效和患者健康產(chǎn)生影響。因此，針對(duì)NAT2基因型和肝功能狀態(tài)進(jìn)行個(gè)體化藥物治療策略的制定，可以提高抗結(jié)核藥物療效，減少藥物不良反應(yīng)的發(fā)生FurtheranalysisshowedthattheNAT2*4genotypewassignificantlyassociatedwithhigherplasmaconcentrationsofisoniazid,oneoftheprimarydrugsusedinthetreatmentoftuberculosis.Thisfindingsuggeststhatindividualswiththisgenotypemayrequireclosermonitoringforpotentialadversedrugreactionsandmaybenefitfromdoseadjustmentsduringtherapy.
