Abstract
In the Arkhangelsk Region, the prevalence of multiple drug-resistant tuberculosis is one of the highest in the world. In 2016, the portion of multiple drug resistant tuberculosis made 33.1% among new cases and 59.5% among relapses. Using new molecular genetic diagnostic techniques allows reducing the time for diagnostics of tuberculosis and drug resistance and should result in the earlier start of adequate treatment.
The goal of the study is to assess the impact of new diagnostic molecular genetic methods on the time period from the first referral for medical care till the start of MDR-TB treatment. It was assumed that the introduction of molecular genetic tests would lead to early initiation of treatment in MDR TB patients (the research project of the International Union Against Tuberculosis and Lung Diseases and Tuberculosis Control Program of Arkhangelsk Region on The PROVE-IT LPA; Policy Relevant Outcomes from Validating Evidence on Impact of Line Probe Assays).
Subjects and Methods. The results of the diagnostic procedure using cultures were compared with the results of the procedure based on molecular genetic tests aimed to detect MDR-TB. 295 MDR TB patients were enrolled into the study, of them, 163 had culture and 132 had molecular genetic tests.
Results. The use of molecular genetic tests in smear-positive patients (AFB+) resulted in the reduction of the time period before initiation of MDRTB treatment by 50 and 66 days (median) versus culture by BacTAlert and absolute concentration on Lowenstein-Jensen medium respectively (p <0.001).
Patients with a negative smear (AFB-), in whom MDR TB was detected by molecular genetic methods started treatment by 78 days earlier (median) versus patients who had culture (Lowenstein-Jensen, p < 0.001). Despite the significant reduction in the time period, even using molecular genetic methods, it took 24 days for cases with AFB+ and 62 days for cases with AFB- to be notified and start treatment of MDR TB.
