Abstract Background: This study aims to identify and compare factors associated with the unfavorable treatment of MDR-TB patients with HIV coinfection in the State of Rio de Janeiro (RJ), Brazil.Methods: A retrospective cohort study with data from TB-MDR patients notified between 2000 and 2016 in RJ. Clinical and epidemiological characteristics and treatment outcomes of patients with HIV positive, negative, and unknown were compared. Bivariate and multivariate Cox hazard regression analysis was conducted to identify factors associated with unfavorable treatment results in patients MDR-TB / HIV positive. Results: Of 2,269 cases, 1,999 (88.1%) had a negative result for HIV, 156 (6.9%) positive and 114 (5.0%) unknown. The proportion of unfavourable outcomes was 43.7% among HIV negative, 52.6% among HIV positive and 43.9% among HIV unknown. Regarding MDR-TB / HIV positive cases, the unfavorable outcomes more prevalent were loss to follow up (24.4%) and death (23.1%). Previous MDR-TB treatment was associated with unsuccess and death. Illicit drugs use was a risk factor for unsuccess and loss to follow up. The six-month culture conversion was a protective factor for unsuccess and death. Administration of antiretroviral therapy was a protective factor for unsuccess, death and failure. The risk of XDR-TB cases for failure was six times higher than that of MDR-TB patients. All XDR-TB / HIV positive cases had unfavorable outcomes.Conclusions: Early identification and immediate initiation of appropriate treatment are key to reducing unfavorable outcomes among MDR-TB / HIV positive. The high proportions of loss to follow-up and death may reflect difficulties in monitoring treatment, due to poor integration between the TB and HIV programs. In addition, none of XDR-TB / HIV positive patient had therapeutic success, highlighting the urgency to incorporate new drugs for the treatment of multidrug-resistant TB by Brazil's Ministry of Health.

BACKGROUND: Brazil ranks 14th worldwide in the number of TB cases and 19th in terms of TB-HIV co-infected cases. This study aims at identifying clinical and demographic factors associated with unsuccessful treatment outcomes (loss to follow-up, treatment failure and death) of HIV-positive patients with multidrug-resistant TB (MDR-TB) in Rio de Janeiro State, Brazil.METHODS: This was a retrospective cohort study of MDR-TB cases notified from 2000 to 2016 in RJ. Cox proportional hazard regression models were used to assess risk factors associated with unsuccessful treatment in HIV-positive patients with MDR-TB.RESULTS: Among 2,269 patients, 156 (6.9%) were HIV-positive and had a higher proportion of unsuccessful treatment outcomes (52.6%) than HIV-negative cases (43.7%). All HIV-positive cases with extensively drug-resistant TB (XDR-TB) had unsuccessful treatment outcomes. Multivariate analysis shows that previous MDR-TB treatment (HR 1.97, 95% CI 1.22–3.18) and illicit drugs use (HR 1.68, 95% CI 1.01–2.78) were associated with a greater hazard of unsuccessful treatment outcomes, while 6-month culture conversion (HR 0.48, 95% CI 0.27–0.84) and use of antiretroviral therapy (ART) (HR 0.51, 95% CI 0.32–0.80) were predictors of reduced risk.CONCLUSIONS: Unsuccessful treatment was higher among HIV patients with MDR-TB than among HIV-negative patients. Prompt initiation of ART and effective interventions are necessary to improve treatment adherence and prevent retreatment cases.

Loss to follow-up (LFU) of ≥2 consecutive months contributes to the poor levels of treatment success in multidrug-resistant tuberculosis (MDR-TB) reported by TB programmes. We explored the timing of when LFU occurs by month of MDR-TB treatment and identified patient-level risk factors associated with LFU.We analysed a dataset of individual MDR-TB patient data (4099 patients from 22 countries). We used Kaplan–Meier survival curves to plot time to LFU and a Cox proportional hazards model to explore the association of potential risk factors with LFU.Around one-sixth (n=702) of patients were recorded as LFU. Median (interquartile range) time to LFU was 7 (3–11) months. The majority of LFU occurred in the initial phase of treatment (75% in the first 11 months). Major risk factors associated with LFU were: age 36–50 years (HR 1.3, 95% CI 1.0–1.6; p=0.04) compared with age 0–25 years, being HIV positive (HR 1.8, 95% CI 1.2–2.7; p<0.01) compared with HIV negative, on an individualised treatment regimen (HR 0.7, 95% CI 0.6–1.0; p=0.03) compared with a standardised regimen and a recorded serious adverse event (HR 0.5, 95% CI 0.4–0.6; p<0.01) compared with no serious adverse event.Both patient- and regimen-related factors were associated with LFU, which may guide interventions to improve treatment adherence, particularly in the first 11 months.

SETTING: The incidence of tuberculosis (TB) has been decreasing in Portugal. Lisbon concentrates the largest number of cases of multidrug-resistant (MDR) TB in the country. This study aims at identifying clinical and demographic factors associated with unfavourable treatment results of patients with MDR-TB in the city.METHOD: The data on 265 MDR-TB cases, notified from 2000 to 2014 in the District of Lisbon, were collected from the Tuberculosis Surveillance System. Unfavourable cases were classified as failure, loss to follow-up (LTFU) and death. Bivariate and multivariate logistic regressions were undertaken to estimate the factors associated with unfavourable outcomes, LTFU and death.RESULTS: The proportion of unfavourable outcomes was 30.5%. These were associated mostly with being male, foreign-born and resistant to kanamycin. Death was associated with being human immunodeficiency virus-positive and resistant to kanamycin. Being foreign-born had a 4.46-fold higher odds of a LTFU outcome than did being Portuguese-born. The foreign-born patients were mostly African immigrants.CONCLUSION: The main finding in this study is that foreign-born patients are associated with a higher probability of unfavourable outcomes than Portuguese-born patients. Therefore, foreign-born patients need more careful monitoring in the control of MDR-TB.

Abstract Background There was a complete lack of information about the treatment outcomes of rifampicin/multidrug resistant (RR/MDR) childhood TB patients (age ≤ 14 years) from Pakistan, an MDR-TB 5th high burden country. Therefore, this study evaluated the socio-demographic characteristics, drug resistance pattern, treatment outcomes and factors associated with unsuccessful outcomes among childhood RR/MDR-TB patients in Pakistan. Methods This was a multicentre retrospective record review of all microbiologically confirmed childhood RR/MDR-TB patients (age ≤ 14 years) enrolled for treatment at seven units of programmatic management of drug-resistant TB (PMDT) in Pakistan. The baseline and follow-up information of enrolled participants from treatment initiation until the end of treatment were retrieved from electronic nominal recording and reporting system. World Health Organization (WHO) defined criterion was used for deciding treatment outcomes. The outcomes of “cured” and “treatment completed” were collectively grouped as successful, whereas “death”, “treatment failure” and “lost to follow-up” were grouped together as unsuccessful outcomes. Multivariable binary logistic regression analysis was used to find factors associated with unsuccessful outcomes. A p-value < 0.05 reflected statistically significant findings. Results A total of 213 children RR/MDR-TB (84 RR and 129 MDR-TB) were included in the study. Majority of them were females (74%), belonged to the age group 10–14 years (82.2%) and suffered from pulmonary TB (85.9%). A notable proportion (37.1%) of patients had no history of previous TB treatment. Patients were resistant to a median of two drugs (interquartile range: 1–4) and 23% were resistant to any second line anti-TB drug. A total of 174 (81.7%) patients achieved successful treatment outcomes with 144 (67.6%) patients being cured and 30 (14.1%) declared treatment completed. Among the 39 (18.3%) patients with unsuccessful outcomes, 35 (16.4%) died and 4 (1.9%) experienced treatment failure. In multivariable analysis, the use of ethambutol had statistically significant negative association with unsuccessful outcomes (odds ratio = 0.36, p-value = 0.02). Conclusions In this study, the WHO target of successful treatment outcomes (≥ 75%) among childhood RR/MDR-TB patients was achieved. The notable proportion of patients with no history of previous TB treatment (37.1%) and the disproportionately high number of female patients (74%) respectively stress for infection control measures and provision of early and high quality care for female drug susceptible TB patients.

Objective. To identify clinical and demographic factors associated with unfavorable treatment outcomes in patients with primary and acquired multidrug-resistant tuberculosis (MDR-TB) in Rio de Janeiro State. Methods. Retrospective cohort study using data on 2 269 MDR-TB cases in 2000–2016. Factors associated with unsuccessful, loss to follow-up, and death outcomes in patients with primary and acquired resistance were investigated with bivariate and multivariate regression. Results. Primary resistance was 14.7% among MDR-TB cases. The unfavorable outcomes proportion was 30.3% in the primary resistance group and 46.7% in the acquired resistance group. There were significant differences in demographic and clinical characteristics between the two groups. Proportionally, the group with primary resistance had more cases among women (46.4% vs. 33.5% in the acquired resistance group), Caucasians (47.3% and 34%), and those with ≥8 years of schooling (37.7% and 27.4%). Extensively drug-resistant TB patients had 12.2-fold higher odds of unsuccessful outcome than MDR-TB patients, and comorbidities had 2-fold higher odds in the primary resistance group. Extensively drug-resistant TB had 5.43-fold higher odds in the acquired MDR-TB group. Bilateral disease and <8 years of schooling were associated with unsuccessful outcome in both groups. Being an inmate had 8-fold higher odds of loss to follow-up in the primary resistance group. Culture conversion by the sixth month was a protective factor for all outcomes. Conclusions. Primary resistance cases of MDR-TB constitute a different transmission reservoir, which is related to other chronic diseases associated with higher acquisition of TB. The poor results observed in Rio de Janeiro State can contribute to increasing the transmission of primary MDR-TB, thus favoring drug resistance.

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 This study aims to evaluate the treatment outcomes and factors associated with unsuccessful treatment outcomes among multidrug-resistant TB (MDR-TB) patients. Method This was a retrospective observational study conducted at the Bahawal Victoria Hospital, Bahawalpur, Pakistan. The sociodemographic, clinical and treatment-related data of MDR-TB patients registered at the study site between June 2014 and December 2016 were retrospectively collected. Patients’ treatment outcomes were categorized on the basis of WHO-recommended criteria. Multivariate binary logistic regression analysis was used to find the independent factors associated with unsuccessful treatment outcomes. Results Out of 179 MDR-TB patients, 106 (59.2%) completed their treatment successfully. The remaining 73 patients (40.8%) had unsuccessful treatment outcomes, among whom 45 (25.1%) died, while 18 (10.1%) were lost to follow-up. Factors associated with unsuccessful treatment outcomes included age ≥40 y (AOR 4.310; p = 0.006), unsuccessful interim treatment outcomes (AOR 5.810; p = 0.032), occurrence of adverse events (AOR 0.290; p = 0.029) and ofloxacin resistance (AOR 2.952; p = 0.042). Conclusion The treatment success rate among the selected cohort of MDR-TB patients was less than the target of ≥75% set by the WHO in the End TB Strategy. The lower treatment success rate at the study site requires urgent attention from clinicians and program managers.

OBJECTIVE: To document the level of drug resistance in MDR-TB patients and to characterize management capacities for their medical care and MDR-TB treatment outcomes in the Kharkiv region of Ukraine. This area has one of the highest frequencies of MDR-TB worldwide.METHODS: A retrospective observational cohort study was performed on registry data from the regional anti-TB dispensary in Kharkiv. All microbiologically confirmed MDR-TB patients registered in 2014 were included. Diagnostic, treatment and post-treatment follow-up data were analysed.RESULTS: Of 169 patients with MDR-TB, 55.0% had pre-extensively drug-resistant (pre-XDR) or XDR resistant patterns. Rapid molecular diagnosis by GeneXpert and liquid M. tuberculosis cultures were only available for 66.9% and 56.8% of patients, respectively. Phenotypic drug-susceptibility testing (DST) for high priority TB drugs (bedaquiline, linezolid, clofazimine) were not available. DST for later generation fluroquinolones was available only in 53.2% of patients. 50.9% of patients had less than 4 drugs in the treatment regimen proven to be effective by DST. More than 23.1% of patients with MDR-TB failed their treatment and only 45.0% achieved a cure.CONCLUSION: The high prevalence of MDR-TB and poor MDR-TB treatment outcomes in the Kharkiv region, is associated with substantial shortages in rapid molecular and phenotypic DST, a lack of high priority MDR-TB drugs, poor treatment monitoring and follow-up capacities.

Tuberculosis (TB) remains a public health burden in the Republic of Karakalpakstan, Uzbekistan. This region-wide retrospective cohort study reports the treatment outcomes of patients registered in the TB electronic register and treated with first-line drugs in the TB Programme of the Republic of Karakalpakstan from 2005–2020 and factors associated with unfavourable outcomes. Among 35,122 registered patients, 24,394 (69%) patients were adults, 2339 (7%) were children, 18,032 (51%) were male and 19,774 (68%) lived in rural areas. Of these patients, 29,130 (83%) had pulmonary TB and 7497 (>22%) had been previously treated. There were 7440 (21%) patients who had unfavourable treatment outcomes. Factors associated with unfavourable treatment outcomes included: increasing age, living in certain parts of the republic, disability, pensioner status, unemployment, being HIV-positive, having pulmonary TB, and receiving category II treatment. Factors associated with death included: being adult and elderly, living in certain parts of the republic, having a disability, pensioner status, being HIV-positive, and receiving category II treatment. Factors associated with failure included: being adolescent, female, having pulmonary TB. Factors associated with loss to follow-up included: being male, disability, pensioner status, unemployment, receiving category II treatment. In summary, there are sub-groups of patients who need special attention in order to decrease unfavourable treatment outcomes.

Abstract Background Treatment outcomes were evaluated of a cohort of new pulmonary tuberculosis (TB) cases that were rifampicin resistant, multidrug-resistant, or extensively resistant during 2013 and 2014 in Brazil. The objective of this study is to identify factors associated with unfavorable treatment outcomes for drug-resistant TB cases. Methods The Brazilian Special Tuberculosis Treatment Information System (SITE-TB) was the main data source. The independent variables were classified into four blocks (block I: individual characteristics; block II: clinical characteristics and proposed treatment; block III: treatment follow-up characteristics; and block IV: TB history). The category of successful therapeutic outcome was compared with lost to follow-up, failure, and death. Considering the multiple outcomes as the dependent variable, the odds ratios (OR) and its respective 95% confidence interval (95% CI) were estimated by multinomial logistic regression. Results After applying the exclusion criteria, 980 (98.8%) individuals were included in the study. Of these, 621 (63.4%) had successful treatment, 163 (16.6%) lost to follow-up, 76 (7.8%) failed, and 120 (12.2%) died. Important factors associated with lost to follow-up in the final model included use of illicit drugs (OR = 2.5 95% CI: 1.57–3.82). Outcome failure was associated with having disease in both lungs (OR = 2.0; 95% CI: 1.09–3.62) and using more than one or not using injectable medication (OR = 2.8; 95% CI: 1.05–7.69). Major factors for the death outcome were at least 60 years old (OR = 3.4; 95% CI: 1.90–6.03) and HIV positive (OR = 2.7; 95% CI: 1.45–4.83). Conclusions The factors associated with unfavorable treatment outcomes were different. Some of these factors are specific to each outcome, which reflects the complexity of providing care to these individuals.
