Tuberculosis: New biomarker indicates individual treatment duration

The treatment of tuberculosis (TB) is long and demanding. In particular, in cases of resistant tuberculosis, the WHO generally recommends a standard treatment duration of at least 18 months, as there are no reliable biomarkers for an early termination. Scientists have now succeeded in identifying a biomarker that points to an individual end of therapy based on the activity of 22 genes. In many cases, this probably allows the treatment to be shortened safely.
