Abstract:
Between the years and , there has been a notable global increase in the estimated mortality rate associated with tuberculosis (TB). According to estimates, the total number of deaths among individuals not infected with HIV amounted to approximately . million in the year . Globally, latent tuberculosis infection has affected more than one-third of the population. Both forms of tuberculosis, namely multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB), which is defined as resistance to rifampicin and isoniazid, as well as resistance to rifampicin, any fluoroquinolone, and at least one of bedaquiline or linezolid, are challenging to manage and require significant financial resources. Furthermore, these forms of TB have a prolonged duration of treatment, are more prone to treatment failure, and can result in the fatality of the patient. XDR-TB, which accounts for approximately .% of cases of MDR-TB, is even more lethal. According to the global tuberculosis (TB) report released by the World Health Organization (WHO) in , the worldwide rate of successful treatment for diagnosed cases of MDR-TB stood at %. In contrast, there was an % success rate observed for all new and relapse cases. MDR-TB and XDR-TB remain significant obstacles to achieving effective global TB control. Therefore, there is an urgent requirement for novel anti-TB medications to address the issue of incipiently untreatable tuberculosis.
