How long is treatment for 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.
Are there new treatments on the horizon for XDR-TB?
Newly developed drugs such as Bdq and Dlm provide new treatment options for MDR/XDR-TB. If trials are successful, treatment for MDR/XDR-TB could be reduced to 6–9 months as standard. By 2022 best practice for managing MDR/XDR-TB will be informed by substantial clinical trial data.
Who is at risk of XDR-TB?
How do people get XDR-TB? People may get XDR-TB in one of two ways. It may develop in a patient who is receiving treatment for active TB, when anti-TB drugs are misused or mismanaged, and is usually a sign of inadequate clinical care or drug management.
What is XDR infection?
Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB).
What causes XDR-TB?
Extensively drug-resistant (XDR) TB refers to MDR-TB strains that are resistant to fluoroquinolones and second-line injectable drugs. The main causes of the spread of resistant TB are weak medical systems, amplification of resistance patterns through incorrect treatment, and transmission in communities and facilities.

What is the difference between XDR and MDR tuberculosis?
Multidrug-resistant tuberculosis (MDR-TB) is practically incurable by standard first-line treatment. However, extensively drug-resistant tuberculosis (XDR-TB) is resistant to both first- and second-line drugs due to drug misuse and mismanagement. Therefore, XDR-TB treatment becomes even harder.
What is pre XDR-TB?
Pre-XDR TB: caused by an organism that is resistant to isoniazid, rifampin, and a fluroquinolone OR by an organism that is resistant to isoniazid, rifampin, and a second-line injectable (amikacin, capreomycin, and kanamycin)
Can drug-resistant TB cured?
In most cases, TB is treatable and curable; however, people with TB can die if they do not get proper treatment. Sometimes drug-resistant TB occurs when bacteria become resistant to the drugs used to treat TB. This means that the drug can no longer kill the TB bacteria.

Is DST good for TB?
While the reproducibility and reliability of DST to injectables is good , there is little data on clinical relevance of the test. Options with XDR-TB are very limited and some strains may be affected in vivo by an injectable agent even though they are testing resistant in vitro.
Which group of drugs is the most effective in treating TB?
Group 3: Fluoroquinolones. Fluoroquinolones are often the most effective anti-TB drugs in an MDR-TB regimen. There are two important recommendations regarding fluoroquinolone use from the 2011 update of the Guidelines for the programmatic management of drug-resistant tuberculosis(1).
What is chapter 6 of the TB treatment guide?
This chapter provides guidance on the strategies for the treatment of multidrug- and extensively drug-resistant TB (M/XDR-TB), with emphasis on regimen design. The treatment of mono- and poly-drug-resistant TB is addressed in Chapter 6. The strategies described in this chapter are largely based on the recommendations from the 2011 update of Guidelines for the programmatic management of drug-resistant tuberculosis, which underwent systematic review and analysis of the evidence for best treatment practice (1).
What is empiric TB?
This Handbook uses the term “empiric” to refer to the initiation of treatment prior to determination of a firm diagnosis of drug-resistant TB. Empiric regimens can be used for both standardized and individualized treatment strategies. For example, an empiric XDR regimen refers to the use of a regimen designed to treat XDR-TB before the diagnosis of XDR-TB is made.
What is the best group of anti-TB drugs?
Group 1: First-line oral agents. Group 1 anti-TB drugs, the most potent and best tolerated, should be used if there is good laboratory evidence andclinical history that suggests that a drug from this group is effective. For patients with strains resistant to low concentrations of isoniazid but susceptible to higher concentrations, the use of high-dose isoniazid may have some benefit (when isoniazid is used in this manner it is considered a Group 5 drug, see below). The newer rifamycins, such as rifabutin, have very high cross-resistance to rifampicin.
What are the different classes of anti-TB drugs?
The classes of anti-TB drugs have traditionally been divided into first- and second-line anti-T B drugs with isoniazid, rifampicin, pyrazinamide, ethambutol and streptomycin being the primary first-line anti-TB drugs. While this classification is used in this document, it also uses a system that classifies the drugs into five different groups. The five-group system is based on efficacy, experience of use, safety and drug class. WHO will be reviewing this five-group system in the next update of the guidelines for the management of MDR-TB in view of the new drugs being introduced and the emerging evidence on its safety and efficacy. The different groups are shown in Table 5.1. Not all drugs in the same group come from the same “drug class” or have the same efficacy or safety. For more information, see individual descriptions of each group in this section. Individual detailed drug information for all anti-TB drugs is provided in the drug information sheets of Part 3.
What is standardized treatment?
Standardized treatment:DRS data from representative patient populations are used to base regimen design in the absence of individual DST. All patients in a defined group or category receive the same regimen (see Chapter 4for risk groups for MDR-TB). Suspected MDR-TB should be confirmed by DST whenever possible.
How early can you start anti-TB treatment?
Antiretroviral therapy (ART) is recommended for all patients with HIV and drug-resistant TB, irrespective of CD4 cell-count, as early as possible (within the first eight weeks) following initiation of the anti-TB treatment (strong recommendation) (1). The drug dosage is usually determined by age and weight.

Drug-susceptible (regular) TB and XDR TB are spread the same way. TB germs are put into the air when a person with TB disease of the lungs or throat coughs, sneezes, speaks, or sings. These germs can float in the air for several hours, depending on the environment. Persons who breathe in the air containing these TB germs can become infected.
Why is XDR TB so serious?
Because XDR TB is resistant to the most powerful first-line and second-line drugs, patients are left with treatment options that are much less effective and often have worse treatment outcomes . XDR TB is of special concern for persons with HIV infection or other conditions that can weaken the immune system. These persons are more likely to develop TB disease once they are infected, and also have a higher risk of death once they develop TB disease.

About 470,000 people fall ill with MDR/RR-TB and about 180,000 die from this form of TB each year, according to WHO estimates. Globally, in 105 countries with representative data, 20% of the people with MDR/RR-TB also have resistance to another potent drug for the treatment of drug-resistant TB – a fluoroquinolone. Extensively drug resistant TB is a more serious form of MDR-TB, with poorer treatment outcomes reported for those affected by this condition.
