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). Almost one in four people in the world is infected with TB bacteria. [1]
There are several ways that drug resistance to TB, and drug resistance in general, can be prevented: [34] [35] Rapid diagnosis & treatment of TB: One of the greatest risk factors for drug-resistant TB is problems in treatment and diagnosis, especially in developing countries. If TB is identified and treated soon, drug resistance can be avoided.
As of October 2006, "Extensively drug-resistant tuberculosis" (XDR-TB) is defined as MDR-TB that is resistant to quinolones and also to any one of kanamycin, capreomycin, or amikacin. [76] The old case definition of XDR-TB is MDR-TB that is also resistant to three or more of the six classes of second-line drugs. [77]
The US Food and Drug Administration (FDA) approved pretomanid only in combination with bedaquiline and linezolid for treatment of a limited and specific population of adults with extensively drug resistant, treatment-intolerant or nonresponsive multidrug resistant pulmonary tuberculosis.
Recognizing different degrees of MDR in bacteria, the terms extensively drug-resistant (XDR) and pandrug-resistant (PDR) have been introduced. Extensively drug-resistant (XDR) is the non-susceptibility of one bacteria species to all antimicrobial agents except in two or less antimicrobial categories.
Resistance to one drug is common, and this is why treatment is usually done with more than one drug. Extensively drug-resistant TB (XDR TB) is TB that is also resistant to the second line of drugs. [14] [17] Resistance of Mycobacterium tuberculosis to isoniazid, rifampin, and other common treatments has become an increasingly relevant clinical ...
Totally drug-resistant tuberculosis (TDR-TB) is a generic term for tuberculosis strains that are resistant to a wider range of drugs than strains classified as extensively drug-resistant tuberculosis. Extensively drug resistant tuberculosis is tuberculosis that is resistant to isoniazid and rifampicin, any fluoroquinolone, and any of the three ...
In 2011, she was diagnosed with extensively drug-resistant tuberculosis (XDR-TB). [2] In mid-2011, Tisile met Jennifer Hughes, a doctor from Médecins Sans Frontières who designed an individually tailored XDR-TB regimen for Tisile. [4] [6] After receiving a combination of linezolid and other drugs, Tisile completed treatment on 29 August 2013. [2]
