Setting: The true prevalence of multidrug-resistant tuberculosis (MDR-TB) in Ukraine is not known. Available data are a decade old and limited to only one province.
Objective: To determine the prevalence of MDR-TB among new and previously treated TB cases in Ukraine and explore the risk factors associated with drug resistance.
Methods: A total of 1550 sputum smear-positive pulmonary TB patients were recruited from 40 clusters throughout Ukraine. Sputum specimens were examined using culture, drug susceptibility testing and pncA gene sequencing.
Results: The proportion of MDR-TB among new and previously treated TB cases was respectively 24.1% (95%CI 20.7-27.6) and 58.1% (95%CI 52.1-64.1). More than one third (38.0%) of MDR-TB or rifampicin (RMP) resistant cases showed resistance to either a fluoroquinolone (FQ) or a second-line injectable agent or both. Resistance to pyrazinamide and FQs was low in patients with RMP-susceptible TB. Among new TB cases, the odds of MDR-TB were higher among patients who were younger, female and living in south-eastern provinces, as well as among human immunodeficiency virus-positive patients who belonged to a low socio-economic group.
Conclusions: Our study showed that the burden of MDR-TB in Ukraine was much greater than previously assumed. Urgent actions are needed to prevent further spread of drug-resistant TB in Ukraine.

Tuberculosis (TB) remains a major global threat, with 10 million new cases and 1.5 million deaths each year. In multidrug-resistant tuberculosis (MDR-TB), resistance is most commonly observed against isoniazid (INH) and rifampicin (RIF), the two frontline drugs.

Multidrug-resistant pathogens pose a major threat to human health, necessitating the identification of new drug targets and lead compounds that are not susceptible to cross-resistance. This study demonstrates that novel reverse thia analogs of the phosphonohydroxamic acid antibiotic fosmidomycin inhibit 1-deoxy-d-xylulose 5-phosphate reductoisomerase (DXR), an essential enzyme for , , and that is absent in humans. Some novel analogs with large α-phenyl substituents exhibited strong inhibition across these three DXR orthologues, surpassing the inhibitory activity of fosmidomycin.

Individuals diagnosed with tuberculosis (TB) and multidrug-resistant (MDR) TB may struggle to return to work after they have completed a rehabilitation program. Multidrug-resistant tuberculosis (MDRTB) has been seen as a condition that is resistant to treatment, hence causing individuals to be economically in-active for considerable periods of time. The aim of the current study was to explore the views of individuals living with MDRTB, individuals with TB, and health professionals treating individuals with TB and MDRTB about the development of a vocational rehabilitation program.

Background: The 2022 invasion of Ukraine by the Russian Federation triggered a refugee crisis, affecting the multidrug-/rifampicin-resistant TB (MDR/RR-TB) prevalence in neighbouring countries. This study examines the epidemiological trends and characteristics of MDR/RR-TB patients in Poland, focusing on the relative contribution of Ukrainian refugees.
Methods: Data from the Polish National Tuberculosis Registry and EPIC Project database, covering MDR/RR-TB cases reported between 2010 and Q1 2024, were analysed.
