Background Patients with HIV and drug-resistant tuberculosis (TB) are at high risk of death. Objectives We investigated the association between rifampicin-resistant TB (RR-TB) and mortality in a cohort of patients who were admitted to hospital at the time of TB diagnosis. Method Adults hospitalised at Khayelitsha Hospital and diagnosed with HIV-associated TB during admission, were enrolled between 2013 and 2016. Clinical, biochemical and microbiological data were prospectively collected and participants were followed up for 12 weeks. Results Participants with microbiologically confirmed TB (n = 482) were enrolled a median of two days (interquartile range [IQR]: 1-3 days) following admission. Fifty-three participants (11.0%) had RR-TB. Participants with rifampicin-susceptible TB (RS-TB) received appropriate treatment a median of one day (IQR: 1-2 days) following enrolment compared to three days (IQR: 1-9 days) in participants with RR-TB. Eight participants with RS-TB (1.9%) and six participants with RR-TB (11.3%) died prior to the initiation of appropriate treatment. Mortality at 12 weeks was 87/429 (20.3%) in the RS-TB group and 21/53 (39.6%) in the RR-TB group. RR-TB was a significant predictor of 12-week mortality (hazard ratio: 1.88; 95% confidence interval: 1.07-3.29; P = 0.03). Conclusion Mortality at 12 weeks in participants with RR-TB was high compared to participants with RS-TB. Delays in the initiation of appropriate treatment and poorer regimen efficacy are proposed as contributors to higher mortality in hospitalised patients with HIV and RR-TB.

HIV 相关结核病住院患者的利福平耐药性和死亡率。

背景 HIV 和耐药结核病 (TB) 患者的死亡风险很高。目标 我们调查了在诊断为结核病时入院的一组患者中利福平耐药结核病 (RR-TB) 与死亡率之间的关联。方法 纳入 2013 年至 2016 年间在 Khayelitsha 医院住院并在入院时被诊断患有 HIV 相关结核病的成人。前瞻性收集临床、生化和微生物学数据,并对参与者进行为期 12 周的随访。结果 经微生物学确诊为结核病的参与者 (n = 482) 在入院后的中位数时间为两天(四分位数间距 [IQR]:1-3 天)。53 名参与者 (11.0%) 患有 RR-TB。患有利福平敏感结核病 (RS-TB) 的参与者接受适当治疗的中位数为一天(IQR:入组后 1-2 天)与 RR-TB 参与者三天(IQR:1-9 天)相比。8 名 RS-TB 参与者 (1.9%) 和 6 名 RR-TB 参与者 (11.3%) 在开始适当治疗之前死亡。RS-TB 组 12 周死亡率为 87/429 (20.3%),RR-TB 组为 21/53 (39.6%)。RR-TB 是 12 周死亡率的重要预测因子(风险比:1.88;95% 置信区间:1.07-3.29;P = 0.03)。结论 与 RS-TB 参与者相比,RR-TB 参与者在 12 周时的死亡率更高。延迟启动适当的治疗和较差的方案疗效被认为是导致住院的 HIV 和 RR-TB 患者死亡率较高的原因。9%)和 6 名 RR-TB 参与者(11.3%)在开始适当治疗前死亡。RS-TB 组 12 周死亡率为 87/429 (20.3%),RR-TB 组为 21/53 (39.6%)。RR-TB 是 12 周死亡率的重要预测因子(风险比:1.88;95% 置信区间:1.07-3.29;P = 0.03)。结论 与 RS-TB 参与者相比,RR-TB 参与者在 12 周时的死亡率更高。延迟启动适当的治疗和较差的方案疗效被认为是导致住院的 HIV 和 RR-TB 患者死亡率较高的原因。9%)和 6 名 RR-TB 参与者(11.3%)在开始适当治疗前死亡。RS-TB 组 12 周死亡率为 87/429 (20.3%),RR-TB 组为 21/53 (39.6%)。RR-TB 是 12 周死亡率的重要预测因子(风险比:1.88;95% 置信区间:1.07-3.29;P = 0.03)。结论 与 RS-TB 参与者相比,RR-TB 参与者在 12 周时的死亡率更高。延迟启动适当的治疗和较差的方案疗效被认为是导致住院的 HIV 和 RR-TB 患者死亡率较高的原因。1.88;95%置信区间:1.07-3.29;P = 0.03)。结论 与 RS-TB 参与者相比,RR-TB 参与者在 12 周时的死亡率更高。延迟启动适当的治疗和较差的方案疗效被认为是导致住院的 HIV 和 RR-TB 患者死亡率较高的原因。1.88;95%置信区间:1.07-3.29;P = 0.03)。结论 与 RS-TB 参与者相比,RR-TB 参与者在 12 周时的死亡率更高。延迟启动适当的治疗和较差的方案疗效被认为是导致住院的 HIV 和 RR-TB 患者死亡率较高的原因。
