Summary

Drug resistant tuberculosis is a growing concern in Estonia. A study found that 28% of new tuberculosis cases had drug-resistant Mycobacterium tuberculosis strains, with 9% being multi-drug resistant.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Public Health

Background:

  • Tuberculosis (TB) remains a significant global health challenge.
  • The incidence of drug-resistant tuberculosis (DR-TB) has been increasing in Estonia.
  • Understanding drug resistance patterns is crucial for effective treatment strategies.

Purpose of the Study:

  • To investigate the drug resistance patterns of Mycobacterium tuberculosis (M. tuberculosis) isolates.
  • To determine the prevalence of resistance to key anti-TB drugs in Estonia.
  • To identify the proportion of multi-drug resistant (MDR-TB) strains.

Main Methods:

  • Analysis of drug susceptibility testing for M. tuberculosis isolates from pulmonary TB cases in Estonia.
  • Inclusion of both new and previously treated TB cases diagnosed in 1994.

  • Testing for resistance against isoniazid, rifampicin, streptomycin, and ethambutol.

    • Main Results:

    • In 1994, 623 TB cases were diagnosed in Estonia.
    • Of 302 culture-verified new cases, 28% exhibited resistance to at least one of the four tested drugs.
    • 9% of new cases harbored multi-drug resistant M. tuberculosis strains.

    Conclusions:

    • The incidence of drug resistance in M. tuberculosis is notably high in Estonia.
    • A significant proportion of new TB cases are resistant to first-line anti-TB drugs.
    • These findings highlight the urgent need for enhanced TB control measures and treatment protocols in Estonia.
