Predictors of Blondal et al for Recurrence of Multidrug-Resistant or Extensively Drug-Resistant Tuberculosis

Patient selection: multidrug-resistant or extensively drug-resistant tuberculosis in Estonia

Risk factors for recurrence of the tuberculosis:

(1) resistance to all injectables

(2) resistance to a greater number of drugs

(3) sputum smear positivity at start of therapy

(4) male sex

(5) birth outside of Estonia

(6) poor adherence

For a patient who has been successfully treated a history of previous therapy for tuberculosis is associated with increased risk of recurrence.

Therapy with as many anti-tuberculosis drugs as possible was associated with a reduced risk for recurrence.
