Journal Title: Актуальна інфектологія - Year 2017, Vol 5, Issue 2
Abstract
Background. The standard treatment of a new case of multidrug-resistant tuberculosis (MDR-TB) according to WHO recommendations in the Republic of Moldova is performed since 2005 showing a low treatment succes. Actually the treatment success rate increased due to excluding of MDR-TB patients from the general cohort. The major rate of patients with low outcome is represented by the failed and lost to follow-up cases. The purpose of the study was to assess the impact of multidrug-resiatnce and MDR-TB on the tuberculosis treatment outcome. Materials and methods. A retrospective selective, descriptive study targeting social, demographic, economic and epidemiological peculiarities, case-management, diagnostic radiological aspects and microbiological characteristics of 187 patients with pulmonary tuberculosis registered during 2013–2015 distributed in two groups: 1st group (61 patients) with established multidrug-resistant strains using conventional cultural methods and the 2nd group (126 patients) with MDR-TB. Results. Multidrug-resistance was established more frequently in new cases and MDR-TB in two thirds of retreated patients. No difference was identified in gender and age distribution, social, economical, educational characteristics; case-management assessment identified a similar proportion of patients revealed by general practitioners and specialists, with low rate of screened high risk groups. All patients from the multidrug-resistant group began the standard treatment for drug-responsiveness tuberculosis before drug susceptibility testing and one third of MDR-TB group was treated from the onset with the DOTS-Plus regimen. Highest success rate was identified in the new-case subgroups of both groups and higher rate of died patients was determined in the retreated subgroups. Such a low rate of patients aggrevates the resistance. Conclusions. Early diagnosis, drug responsiveness testing and raising awareness among about treatment compliance will improve disease outcome.
