AI simplified

Abstract

In 2015, there were an estimated 10.4 million new tuberculosis (TB) cases worldwide.

  • Despite the availability of a four-drug treatment regimen for 40 years, TB remains a significant health issue.
  • The rise in multidrug-resistant (MDR-TB), extensively-drug resistant (XDR-TB), and totally drug-resistant (TDR-TB) cases is concerning.
  • MDR-TB and XDR-TB are associated with lower cure rates and higher mortality due to treatment challenges.
  • Recent developments include new drugs and regimens aimed at treating all forms of TB.
  • There is growing scientific interest in host-directed therapies (HDTs) to find new treatments for MDR-TB.
  • The review highlights discoveries of new drugs and examines the molecular mechanisms behind drug resistance in Mycobacterium tuberculosis.
