How often is treatment of MDR-TB successful?
The overall treatment success rate for all patients was 57% (95% CI: 52%–61%), 58% for patients with MDR-TB (n = 272) and 30% for patients with XDR-TB (n = 3) (Table 1). Overall, 76 (21%) patients had poor treatment outcomes (13 patients died and 63 patients had treatment failure).

What are the MDR-TB suspect criteria?
A confirmed MDR TB case is an MDR TB suspect who is sputum culture positive and whose TB is due to bacilli that are resistant in-vitro to at least isoniazid and rifampicin (the DST result being from an RNTCP accredited IRL).
What is the total duration of treatment of Multi Drug Resistant Tuberculosis?
Treatment of MDR-TB lasts for a long duration of approximately 2 years and consists of a combination of multiple second-line drugs, which are more expensive, less effective, and more toxic than the first-line drugs. Therefore, treatment outcomes for MDR-TB are poor, with a success rate of approximately 54% [2].
How long does it take to cure XDR TB?
MDR- and XDR-TB need prolonged treatment duration, from 18 to 24 months after sputum culture conversion, as recommended by the World Health Organization (WHO) [2]. A prolonged duration of treatment may lead to poor adherence, higher cost and undue toxicity.

Of the total TB patients with known treatment outcome, the overall treatment success rate was 82.5%. Of these 65 (28%) were cured and 126 (54.3%) had completed their treatment. The treatment success rate of HIV-co-infected TB patients (n=40) included in TB treatment outcome analysis was 77.5%.
What is treatment outcome?
Treatment outcome research was defined by Mowrer (1953) as a situation whereby the “emphasis is upon measuring significant aspects of personality before and after treatment and noting the nature and extent of the resulting changes” (p. 4).

What is the WHO guideline?
In November 2015, the World Health Organization (WHO) convened a meeting of a Guideline Development Group (GDG) for the update of policy recommendations on the treatment of drug-resistant TB. The GDG was composed of a multidisciplinary group of tuberculosis (TB) and drug-resistant TB experts external to WHO. Before the meeting, the members of the GDG and the WHO Guideline Steering Committee had decided upon the priority questions in the treatment and care of patients with drug-resistant TB to be considered for the update of the guidelines. The scope of the 2016 update comprised the following: 1 The optimal combination of medicines and approach towards regimen design for TB patients (both adults and children) with isoniazid-resistant, rifampicin-resistant (RR-TB), multidrug-resistant (MDR-TB), and extensively drug-resistant (XDR-TB) forms of TB, as well as for patients with M. bovis disease. 2 The effectiveness and safety of standardized regimens lasting up to 12 months for the treatment of patients with MDR-TB (“shorter regimens”) when compared with longer treatment. 3 The effect of delay in starting treatment on treatment outcomes for patients with drugresistant TB. 4 The effect of surgical interventions on treatment outcomes for patients with drug-resistant TB.
How long does a standardized regimen last?
The effectiveness and safety of standardized regimens lasting up to 12 months for the treatment of patients with MDR-TB (“shorter regimens”) when compared with longer treatment.
Abstract
Antimicrobial resistance is a major public health problem globally. Likewise, forms of tuberculosis (TB) resistant to first- and second-line TB medicines present a major challenge for patients, healthcare workers and healthcare services.
Short abstract
New WHO guidelines on the treatment of drug-resistant tuberculosis (TB) contain the latest recommendations on shorter or longer all oral treatment regimens for patients with drug-resistant TB, including the medicines to be used and other supportive measures https://bit.ly/2UJeib7
Introduction
Antimicrobial resistance is a major public health problem globally and has become a health security concern worldwide [ 1, 2 ]. Drug-resistant bacterial infections are on the rise globally, which has placed sharp focus on drug-resistant tuberculosis (TB), its diagnosis and treatment [ 3 ].
Process of guideline development
Overall, guideline development within the WHO is coordinated by technical programmes, ensuring that the process is evidence based and transparent, firmly relying on the highest ethical standards in science.
The scope of the updated guidelines
The scope of the 2020 guidelines update covered four areas, as follows.
Analysis and review of evidence
Detailed statistical analysis plans were prepared for the analytical approach to each PICO question. Descriptive analyses were performed to determine population characteristics and to provide information on the variables needed for matching and adjustment.
Summary of evidence and analyses
The evidence reviewed on the shorter all-oral bedaquiline-containing regimen was derived from programmatic data from South Africa's Electronic Drug-Resistant Tuberculosis Register ( www.edrweb.net ).
