Uzbekistan has a high burden of drug-resistant tuberculosis (TB). Although conventional treatment for multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) has been available since 2013, there has been no systematic documentation about its use and effectiveness. We therefore documented at national level the trends, characteristics, and outcomes of patients with drug-resistant TB enrolled for treatment from 2013–2018 and assessed risk factors for unfavorable treatment outcomes (death, failure, loss to follow-up, treatment continuation, change to XDR-TB regimen) in patients treated in Tashkent city from 2016–2017. This was a cohort study using secondary aggregate and individual patient data. Between 2013 and 2018, MDR-TB numbers were stable between 2347 and 2653 per annum, while XDR-TB numbers increased from 33 to 433 per annum. At national level, treatment success (cured and treatment completed) for MDR-TB decreased annually from 63% to 57%, while treatment success for XDR-TB increased annually from 24% to 57%. On multivariable analysis, risk factors for unfavorable outcomes, death, and loss to follow-up in drug-resistant TB patients treated in Tashkent city included XDR-TB, male sex, increasing age, previous TB treatment, alcohol abuse, and associated comorbidities (cardiovascular and liver disease, diabetes, and HIV/AIDS). Reasons for these findings and programmatic implications are discussed.

Abstract Background Drug-resistant tuberculosis (DR-TB) is the barrier for global TB elimination efforts with a lower treatment success rate. Loss to follow-up (LTFU) in DR-TB is a serious problem, causes mortality and morbidity for patients, and leads to wide spreading of DR-TB to their family and the wider community, as well as wasting health resources. Prevention and management of LTFU is crucial to reduce mortality, prevent further spread of DR-TB, and inhibit the development and transmission of more extensively drug-resistant strains of bacteria. A study about the factors associated with loss to follow-up is needed to develop appropriate strategies to prevent DR-TB patients become loss to follow-up. This study was conducted to identify the factors correlated with loss to follow-up in DR-TB patients, using questionnaires from the point of view of patients. Methods An observational study with a cross-sectional design was conducted. Study subjects were all DR-TB patients who have declared as treatment success and loss to follow-up from DR-TB treatment. A structured questionnaire was used to collect information by interviewing the subjects as respondents. Obtained data were analyzed potential factors correlated with loss to follow-up in DR-TB patients. Results A total of 280 subjects were included in this study. Sex, working status, income, and body mass index showed a significant difference between treatment success and loss to follow-up DR-TB patients with p-value of 0.013, 0.010, 0.007, and 0.006, respectively. In regression analysis, factors correlated with increased LTFU were negative attitude towards treatment (OR = 1.2; 95% CI = 1.1–1.3), limitation of social support (OR = 1.1; 95% CI = 1.0–1.2), dissatisfaction with health service (OR = 2.1; 95% CI = 1.5–3.0)), and limitation of economic status (OR = 1.1; 95% CI = 1.0–1.2)). Conclusions Male patients, jobless, non-regular employee, lower income, and underweight BMI were found in higher proportion in LTFU patients. Negative attitude towards treatment, limitation of social support, dissatisfaction with health service, and limitation of economic status are factors correlated with increased LTFU in DR-TB patients. Non-compliance to treatment is complex, we suggest that the involvement and support from the combination of health ministry, labor and employment ministry, and social ministry may help to resolve the complex problems of LTFU in DR-TB patients.

Objective — to study the effectiveness of treatment of MDR-TB (multidrug-resistant tuberculosis) and preXDR-TB/XDR-TB (pre-extensively and extensively drug resistant tuberculosis), depending on the composition of ITRs (individualized treatment regimens). Materials and methods. Тhe prospective observational study included 566 patients with MDR/preXDR-TB and XDR-TB during 2016—2020 on the scientific clinical bases of the SI «National Institute of Phthisiology and Pulmonology named after F.G. Yanovsky NAMS of Ukraine» and ME «Kryvyi Rih Anti-tuberculosis Dispensary» Dnipropetrovsk Regional Council Department. Patients were prescribed individualized treatment regimens in cases where short (standard or modified) regimens could not be prescribed. Patients were divided into comparison groups: 469 of them were treated with antimycobacterial therapy including bedaquiline and other effective antimycobacterial drugs groups A—C (without delamanid) — group 1. And 97 patients who were treated with the inclusion of both new antimycobacterial drugs (bedaquiline and delamanid) — group 2. Results and discussion. Regardless of whether the delamanid, in addition to bedaquiline and other drugs selected for the scheme according to WHO recommendations, «effective treatment» was found in 91.3 against 88.6 % of patients. In the remote period (6-month — 4-year follow-up period) there was no recurrence of the disease, regardless of the composition of the regime. The loss of treatment effectiveness was due to deaths from non-tuberculosis reasons and those lost for follow-up. Conclusions. For highly effective treatment, individualized regimens should include bedaquidine and linezolid from group A, and for previously ineffectively treated patients, clofazimine and carbapenems must be included (possibility to include 4 or more effective AMDs in ITR). For patients with fluoroquinolone resistance, treatment should include delamanid.

BACKGROUND: Bedaquiline (BDQ) has not been extensively studied among patients co-infected with HIV drug-resistant tuberculosis (DR-TB). We compared treatment outcomes in DR-TB patients treated with BDQ- and linezolid (LZD) containing regimens to historic controls treated with second-line injectable-containing regimens.METHODS: Retrospective cohort study of consecutive DR-TB patients initiated on BDQ- and LZD-containing regimens at a TB referral hospital in KwaZulu-Natal, South Africa. Participants were prospectively followed through 24 months for treatment outcome and adverse events. Outcomes were compared to a historic control cohort of DR-TB HIV patients enrolled at the same facility prior to BDQ introduction.RESULTS: Adult DR-TB patients initiating BDQ between January 2014 and November 2015 were enrolled (n = 151). The majority of patients were female (52%), HIV co-infected (77%) and on antiretroviral therapy (100%). End of treatment outcomes included cure (63%), TB culture conversion (83%), completion (0.7%), loss to follow-up (15%), treatment failure (5%), and death (17%). Compared to historic controls (n = 105), patients treated with BDQ experienced significantly higher TB culture conversion and cure, with significantly lower mortality. Adverse effects were common (92%), and most frequently attributed to LZD (24.1%). QT segment prolongation was common but without clinical sequelae.CONCLUSION: Treatment with BDQ- and LZD-containing regimens was associated with improved treatment outcomes and survival in DR-TB HIV patients.
