Surveillance studies and outbreak investigations indicate that an extensively drug-resistant (XDR) form of tuberculosis (TB) is increasing in prevalence worldwide. In outbreak settings among HIV-infected, there is a high-case fatality rate. Better outcomes occur in HIV-uninfected, particularly if drug susceptibility test (DST) results are available rapidly to allow tailoring of drug therapy. This review will be presented in two segments. The first characterizes the problem posed by XDR-TB, addressing the epidemiology and evolution of XDR-TB and treatment outcomes. The second reviews technologic advances that may contribute to the solution, new diagnostics, and advances in understanding drug resistance and in the development of new drugs.
监测研究和疫情调查表明,广泛耐药结核病(TB)在全球的流行率正在上升。在感染艾滋病毒的疫情环境中,该病的病死率很高。在未感染艾滋病毒的情况下,结果较好,特别是如果药物敏感性试验(DST)结果能够迅速获得,从而能够调整药物治疗。本综述将分为两部分呈现。第一部分描述了广泛耐药结核病带来的问题,涉及广泛耐药结核病的流行病学和演变以及治疗结果。第二部分回顾了可能有助于解决问题的技术进展、新诊断方法以及对耐药性的理解和新药开发方面的进展。
