Multidrug-resistant tuberculosis (MDR-TB) and rifampicin-resistant tuberculosis (RR-TB) pose significant challenges to global tuberculosis prevention and treatment efforts. At present, the chemotherapy of MDR/RR-TB is still hampered by prolonged treatment duration and suboptimal success rates. In 2019, the Chinese Medical Association Tuberculosis Branch issued the Chinese Expert Consensus on the Treatment of MDR-TB and RR-TB, which has provided essential guidance for standardizing the diagnosis, treatment, and clinical management of MDR/RR-TB in China. In response to recent advances in global evidence-based medicine and in consideration of China's specific context, the Chinese Medical Association Tuberculosis Branch recently convened a panel of experts to develop the Chinese Guidelines for the Chemotherapy of MDR/RR-TB (2026 Edition). This guideline provides updated recommendations regarding the definition of drug-resistant tuberculosis, selection and adjustment of short-course and long-course regimens, treatment monitoring, management of special populations, and standardized management of adverse drug reactions. Each recommendation is supported by an evidence-based rationale, the clinical questions addressed, and practical implementation suggestions. A total of 14 recommendations are presented, aiming to provide a robust clinical evidence base and to support informed decision-making for the standardized treatment of MDR/RR-TB. The key recommendations are as follows.Recommendation 1: For adolescents (aged 14 years and above) and adults with MDR/RR-TB, the 6-month regimen comprising bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) is recommended over the 9-month or longer (18-month) regimens (1, B).Recommendation 2: For MDR/RR-TB patients with or without fluoroquinolones resistance (including children of all ages, pregnant and breastfeeding women), the 6-month regimen comprising bedaquiline, delamanid, linezolid, levofloxacin, and clofazimine (BDLLfxC) is recommended (1, B).Recommendation 3: For MDR/RR-TB patients susceptible to fluoroquinolones, the 9-month all-oral regimen comprising bedaquiline, levofloxacin (or moxifloxacin), protionamide (or linezolid for two months), clofazimine, ethambutol, high-dose isoniazid, and pyrazinamide [4-6 Bdq (6m)-Lfx (Mfx)-Pto (Lzd2m)-Cfz-E-Hhigh-dose-Z/5Lfx (Mfx)-Cfz-E-Z] is recommended over longer (18-month) regimens (2, B).Recommendation 4: For MDR/RR-TB patients susceptible to fluoroquinolones, the modified 9-month all-oral regimens (BLMZ, BLLfxCZ and BDLLfxZ) are recommended over the currently recommended longer (18 months) regimens. The recommended order of priority among these regimens is BLMZ>BLLfxCZ>BDLLfxZ(2, B).Recommendation 5: When drug accessibility is limited, for MDR/RR-TB patients susceptible to both fluoroquinolones and amikacin, the 9- to 12-month short-course regimen containing an injectable agent may be used in place of the longer regimens (18 months) (2, B).Recommendation 6: For MDR/RR-TB patients susceptible to fluoroquinolones, the 9-month regimen comprising bedaquiline, linezolid, levofloxacin, clofazimine, and cycloserine may be used in place of the longer regimens (18 months) (2, D).Recommendation 7: For MDR/RR-TB patients receiving long-course treatment, the regimen should include all three Group A agents and at least one Group B agent so that treatment starts with at least four anti-tuberculosis drugs likely to be effective, and that at least three agents are included for the rest of the treatment if bedaquiline is stopped. If only one or two Group A agents are used, both Group B agents are to be included. If the regimen cannot be composed from agents from Groups A and B alone, Group C agents should be added to complete it (1, B).Recommendation 8: The optimal regimen for MDR/RR-TB patients should be individualized based on reliable baseline drug-susceptibility testing results, previous treatment history, and clinical characteristics. Short-course regimens are preferred; for patients who are not eligible for short-course regimens, individualized longer regimens may be selected based on drug susceptibility testing results (Good Practice Statement, GPS).Recommendation 9: Short-course regimens are fixed, standardized combination treatments. When adverse drug reactions occur, dose adjustment is permitted; however, early discontinuation or substitution of any drug to modify the regimen is not recommended (with the exception of linezolid-related adverse events). Adjustments due to treatment failure or intolerance should be made after consultation with a clinical expert panel (GPS).Recommendation 10: MDR/RR-TB patients undergoing treatment should be monitored for clinical efficacy and adverse events through symptom assessment, physical examination, laboratory tests, and chest imaging. When necessary, examinations such as electrocardiography, hearing tests, and visual field assessments should also be performed. Where feasible, patients on long-course regimens should ideally undergo monthly sputum smear microscopy and Mycobacterium tuberculosis culture during treatment. Patients on short-course regimens may be monitored at an appropriately increased frequency (1, B).Recommendation 11: The treatment principles for MDR/RR-TB in individuals of all ages-including children, adolescents, pregnant and breastfeeding women, and the elderly-are consistent with those for general MDR/RR-TB patients. Short-course regimens are still preferred (1, B).Recommendation 12: The design principles of anti-tuberculosis regimens for patients with MDR/RR-TB and HIV/AIDS co-infection should follow the same principles as those for HIV-negative patients, with careful consideration of drug-drug interactions between anti-tuberculosis and antiretroviral agents (1, A).Recommendation 13: Patients co-infected with MDR/RR-TB and HIV/AIDS should receive antiretroviral therapy concurrently with anti-tuberculosis treatment (regardless of CD4+ T-cell count), ideally within 8 weeks. For those with central nervous system tuberculosis, antiretroviral therapy should be initiated between 4 and 8 weeks after starting anti-tuberculosis treatment (2, D).Recommendation 14: MDR/RR-TB patients with chronic hepatitis B virus (HBV) infection who meet criteria for antiviral therapy should initiate anti-HBV treatment as soon as possible. Anti-tuberculosis treatment may initiate concurrently or after liver function has stabilized. For those with chronic hepatitis C virus infection, concurrent initiation of anti-tuberculosis treatment and direct-acting antiviral agents is recommended (2, D). 耐多药结核病(multidrug-resistant tuberculosis,MDR-TB)与利福平耐药结核病(rifampicin-resistant tuberculosis,RR-TB)是全球结核病防治工作面临的重大挑战。目前,MDR/RR-TB的化学治疗仍存在疗程较长、治疗成功率偏低等问题。中华医学会结核病学分会在2019年发布了《中国耐多药和利福平耐药结核病治疗专家共识》,为我国MDR/RR-TB的规范化诊疗和临床处置能力提升提供了重要指导。为进一步响应全球循证医学进展,结合我国实际国情,中华医学会结核病学分会组织结核病领域专家,制订了《中国耐多药/利福平耐药结核病化学治疗指南(2026年版)》。本指南重点围绕耐药结核病定义、短程与长程治疗方案的选择及调整策略、治疗期间的监测、特殊人群的治疗以及药物不良反应的规范化管理等方面,提出更新建议及推荐意见,并辅以循证依据、临床疑问及实施建议。本指南共形成14条推荐意见,旨在为MDR/RR-TB的规范化治疗提供坚实的临床证据和决策依据。主要推荐意见如下。推荐意见1:对于14岁及以上青少年和成人MDR/RR-TB患者,应采用6个月BPaLM治疗方案,而非 9 个月或更长(18 个月)疗程方案(1B)。推荐意见2:对于伴或不伴氟喹诺酮类药物耐药的MDR/RR-TB患者(包括全年龄段儿童、妊娠和哺乳期妇女),可采用6个月BDLLfxC治疗方案(1B)。推荐意见3:对氟喹诺酮类药物敏感的MDR/RR-TB患者,可使用9个月全口服治疗方案[4~6Bdq(6m)-Lfx(Mfx)-Pto(Lzd2m)-Cfz-E-Hhigh-dose-Z/5Lfx(Mfx)-Cfz-E-Z],而非更长疗程(18个月)方案(2B)。推荐意见4:对氟喹诺酮类药物敏感的MDR/RR-TB患者,可使用9个月全口服方案(BLMZ、BLLfxCZ和BDLLfxZ)替代更长疗程(18个月)方案。优先级使用顺序依次为:BLMZ、BLLfxCZ、BDLLfxZ(2B)。推荐意见5:在药物可及性受限时,对于氟喹诺酮类药物及阿米卡星敏感的MDR/RR-TB患者,可使用9~12个月的含注射剂短程治疗方案替代长程(18个月)治疗方案(2B)。推荐意见6:对氟喹诺酮类敏感的MDR/RR-TB患者,也可选用9个月Bdq-Lzd-Lfx-Cfz-Cs方案替代长程(18个月)治疗方案(2D)。推荐意见7:对于接受长程治疗的MDR/RR-TB患者,治疗方案应包含全部3种A组以及至少1种B组药物,以确保治疗初期至少有4种可能有效药物;同时保证停用贝达喹啉后,方案至少包含3种有效药物;如仅能使用1~2种A组药物,则需同时包含2种B组药物。若仅通过 A 组和 B 组药物无法组成有效治疗方案,则应加入C组药物以完善治疗方案(1B)。推荐意见8:对MDR/RR-TB患者实施最佳方案需基于患者可靠的基线药敏试验结果、既往治疗史及临床特征等进行个体化决策。优先选择短程治疗方案,对于不适用短程方案的患者,可根据药敏试验结果选择个体化长程方案(GPS)。推荐意见9:短程方案属于固定标准化治疗组合,当患者出现药物不良反应时,可以进行剂量调整,但不建议过早停用或替换任何药物(利奈唑胺相关不良事件除外)来修改方案。若因疗效不佳或组合方案中药物无法继续使用时,需经过临床专家组讨论后调整方案(GPS)。推荐意见10:对于接受治疗的MDR/RR-TB患者,需进行临床疗效及不良反应的监测,包括临床症状、体格检查、实验室检查以及胸部影像学检查,必要时进行心电图、听力、视力视野等检查。接受长程治疗方案的患者,若条件允许,最好在治疗期间每月同时开展痰涂片镜检及痰分枝杆菌培养检查以监测治疗效果,接受短程治疗方案者可适当增加监测频率(1B)。推荐意见11:全年龄段儿童及青少年、妊娠期和哺乳期妇女及老年人MDR/RR-TB治疗原则与普通MDR/RR-TB患者一致,仍优先选择短程治疗方案(1B)。推荐意见12:MDR/RR-TB和HIV/AIDS共病患者的抗结核治疗方案制定与HIV阴性患者相同,但需要注意抗结核药物与抗逆转录病毒药物的相互作用(1A)。推荐意见13:MDR/RR-TB和HIV/AIDS共病患者,应在抗结核治疗的同时进行抗逆转录病毒治疗(不考虑CD4+T淋巴细胞计数),最好于8周内启动抗逆转录病毒治疗。合并中枢神经系统结核时,应在抗结核治疗开始4周后、8周内启动抗逆转录病毒治疗(2D)。推荐意见14:MDR/RR-TB合并慢性乙型病毒性肝炎患者,具有抗病毒治疗指征者,应尽快开启抗乙型肝炎病毒治疗,抗结核治疗可同时或待肝功能稳定后尽快启动。合并慢性丙型病毒性肝炎患者,建议同时启动抗结核和直接抗病毒药物抗丙型肝炎病毒治疗(2D)。.
