Tuberculosis (TB) is a leading cause of morbidity and mortality worldwide. Diagnosis, treatment, and prevention of TB has become more complex because of resistance to commonly used antituberculous drugs. (See "Epidemiology and molecular mechanisms of drug-resistant tuberculosis".)

Management of drug-resistant TB can be difficult and may necessitate use of second-line drugs and/or surgical resection. Management of such patients should be undertaken by individuals with expertise in this area or in very close consultation with such individuals, in the context of a supportive public health infrastructure [1,2]. Good patient outcomes depend upon rapid and accurate diagnosis together with administration of proper therapy with close monitoring.

Issues related to diagnosis, treatment, and prevention of drug-resistant TB are reviewed here. Issues related to extensively drug-resistant TB are discussed separately as are issues related to treatment of drug-susceptible TB. (See "Epidemiology of extensively drug-resistant tuberculosis" and "Diagnosis and treatment of extensively drug-resistant tuberculosis" and "Treatment of pulmonary tuberculosis in HIV-uninfected adults" and "Treatment of pulmonary tuberculosis in HIV-infected adults".)


Definitions to describe the different types of drug-resistant tuberculosis (TB) include:

The term "drug-resistant tuberculosis" refers to TB caused by an isolate of Mycobacterium tuberculosis that is resistant to one or more antituberculous drugs.
