Isoniazid (INH) mono-resistance and tuberculosis (TB) treatment success: analysis of European surveillance data, 2002 to 2014

Introduction: Isoniazid (INH) is an essential drug for tuberculosis (TB) treatment. Resistance to INH may increase the likelihood of negative treatment outcome. Aim: We aimed to determine the impact of INH mono-resistance on TB treatment outcome in the European Union/European Economic Area and to identify risk factors for unsuccessful outcome in cases with INH mono-resistant TB. Methods: In this observational study, we retrospectively analysed TB cases that were diagnosed in 2002–14 and included in the European Surveillance System (TESSy). Multilevel logistic regression models were applied to identify risk factors and correct for clustering of cases within countries. Results: A total of 187,370 susceptible and 7,578 INH mono-resistant TB cases from 24 countries were included in the outcome analysis. Treatment was successful in 74.0% of INH mono-resistant and 77.4% of susceptible TB cases. In the final model, treatment success was lower among INH mono-resistant cases (Odds ratio (OR): 0.7; 95% confidence interval (CI): 0.6–0.9; adjusted absolute difference in treatment success: 5.3%). Among INH mono-resistant TB cases, unsuccessful treatment outcome was associated with age above median (OR: 1.3; 95% CI: 1.2–1.5), male sex (OR: 1.3; 95% CI: 1.1–1.4), positive smear microscopy (OR: 1.3; 95% CI: 1.1–1.4), positive HIV status (OR: 3.3; 95% CI: 1.6–6.5) and a prior TB history (OR: 1.8; 95% CI: 1.5–2.2). Conclusions: This study provides evidence for an association between INH mono-resistance and a lower likelihood of TB treatment success. Increased attention should be paid to timely detection and management of INH mono-resistant TB.

Background Tuberculosis (TB) is one of the major public health problems in Ethiopia. Determining treatment outcome of TB cases could help to understand the effectiveness of TB control efforts. The objective of this study was to assess TB treatment outcome and associated factors and determine the risk factors of death among TB cases who were on Directly Observed Treatment Short course (DOTS). Methodology We analyzed a retrospective data for TB cases who were on DOTS at Dilla Referral Hospital from July 2011- June 2016. The study population was TB cases with known HIV status and whose treatment outcome was evaluated at the Hospital. Data were entered, cleaned and analyzed using statistical package SPSS for windows, version 20. Result Out of 899 registered TB cases, 731 included in this analysis. Of these cases, 424 (58.0%) were male and 334 (45.7%) were in the age group of below 25 years. Treatment success rate of TB was 675 (92.3%) and death rate was 18 (2.5%). Treatment outcome showed statistically significant variation by HIV status (P < 0.001). HIV status of the TB cases and pretreatment weight were associated with TB treatment outcome. HIV status of the TB cases was associated with death of the TB cases (Adjusted Odds Ratio (AOR) 5.0; CI 95%: 1.8–13.5). Conclusion TB treatment success rate found in this study was high. Patient’s weight and HIV status were associated with treatment outcome. Moreover, HIV status predicted death of TB cases. Cautious treatment follow-up and defaulter tracing mechanisms for TB cases with these risk factors were suggested.

Monitoring the treatment outcome (TO) of tuberculosis (TB) is essential to evaluate the effectiveness of the intervention and to identify potential barriers for TB control. The global target is to reach a treatment success rate (TSR) of at least 85%. We aimed to assess the TB TO in the European Union and European Economic Area (EU/EEA) between 2002 and 2011, and to identify factors associated with unsuccessful treatment. Only 18 countries reported information on TO for the whole observation period accounting for 250,854 new culture-confirmed pulmonary TB cases. The 85% target of TSR was not reached in any year between 2002 and 2011 and was on average 78%. The TSR for multidrug-resistant (MDR)-TB cases at 24-month follow-up was 49%. In the multivariable regression model, unsuccessful treatment was significantly associated with increasing age (odds ratio (OR) = 1.02 per a one-year increase, 95% confidence interval (CI): 1.02–1.02), MDR-TB (OR = 8.7, 95% CI: 5.09–14.97), male sex (OR = 1.40, 95% CI: 1.28–1.52), and foreign origin (OR = 1.32, 95% CI: 1.03–1.70). The data highlight that special efforts are required for patients with MDR-TB and the elderly aged ≥65 years, who have particularly low TSR. To allow for valid monitoring at EU level all countries should aim to report TO for all TB cases.

Background: Refugees are vulnerable to tuberculosis (TB) infection. Tracking of program performance is needed to improve TB care and prevention. The objective of this study was to assess the trends of TB treatment outcomes of notified cases in three refugee camps in Sudan from 2014 to 2017. Methods: This study was a historical cohort study. Sex, age, type of TB, TB patient category, and treatment outcome of all TB cases registered in three refugee camps (Al Kashafa, Shagarab, Wadsherify) from January 1, 2014 to December 31, 2017 were collected from the TB register. Multivariable logistic regression was performed to explore factors for unsuccessful TB treatment. Results: A total of 710 TB cases of which 53.4% were men, 22.1% children (<15 years), and 36.2% extrapulmonary TB (EPTB) were registered. Overall, the TB treatment success rate was 75.7% with a declining trend from 86.2% in 2015 to 63.5% in 2017. On average, 11.4% were lost to follow-up (LTFU), 6.6% died, 5.9% were not evaluated, and in 0.3% the treatment failed. Being 15–24 years old and having EPTB were significantly associated with unsuccessful treatment outcome. Conclusion: The treatment success rate in the refugee camp in 2017 (63.5%) was far lower than the national treatment success rate (78%) and the End TB global target (≥90%) that needs to be improved. LTFU, died, and not evaluated outcomes were high which indicated the necessity to improve the TB treatment program.

The Impact

Introduction. The convergence of TB and HIV dual epidemics is a major public health challenge in Ghana as well as many developing countries. Treatment outcome monitoring is a vital part of the surveillance needed to successfully eliminate TB. The impact of HIV status and demographic and treatment-related factors on adverse TB treatment outcome has not been studied in the Greater Accra Regional Hospital. This study determined factors associated with TB treatment outcome in patients with TB-HIV coinfection and TB-only infection in the hospital. Method. A cross-sectional study was carried out in the Greater Accra Regional Hospital. We reviewed TB treatment cards of patients who received treatment for tuberculosis in the hospital from 2008 to 2016. Data on treatment outcome and sociodemographic and clinical characteristics were extracted on TB-only-infected and TB/HIV-coinfected patients. The chi-squared test and binary and multiple logistic regression models were used to assess factors associated with adverse treatment outcome. Results. Out of the 758 patient records analyzed, 174 (22.9%) were TB-HIV-coinfected patients. Overall treatment success for all TB patients was 88.1% (668/758). About 11.9% (90/758) of the patients had an adverse treatment outcome, including treatment failure 0.9% (7/758), defaulting 0.9% (7/758), and death 10.0% (76/758). TB-HIV-coinfected patients’ treatment success was 78.1% (136/174). TB-only patients’ treatment success was 91.4% (532/582). Independent predictors of adverse treatment outcome were found to be as follows: being HIV positive (aOR: 3.85, 95% CI: 2.19-6.75; p<0.01); aged 65 and above (aOR: 1.76, 95% CI: 1.44-1.54; p=0.01); and previously failed TB treatment (aOR: 5.02, 95% CI: 2.09-28.87; p<0.01). Conclusion. Treatment outcome for TB-HIV-coinfected patients is below the WHO target. HIV status, age, and category of patient of the TB patients were associated with adverse treatment outcome. Strengthening the TB/HIV collaborative efforts by stakeholders is required for good treatment outcomes.

Abstract Monitoring of tuberculosis (TB) treatment outcome is essential to ensure an effective TB control program. In this nationwide retrospective cohort study from Denmark we present TB treatment outcome rates and risk factors associated with an unfavourable outcome. All patients notified with pulmonary TB from 2009 through 2014 were included. Logistic regression analyses were used to identify risk factors for unfavourable outcome. In total, 1681 pulmonary TB cases were included. TB treatment success rates increased during the study period. In 2014, the treatment success rate reached 85% for new culture positive cases whereas 7% cases interrupted treatment. The mortality decreased during the study period from 12.3% to 4.1%. Several risk factors associated with unfavourable outcome were identified in a multivariable model: male (OR: 2.56), Greenlandic origin (OR: 1.80), abuse of alcohol (OR: 2.90), history of mental disorder (OR: 2.46), and anaemia at time of treatment initiation (OR: 1.92). In a TB low incidence setting such as the Danish, it is important to maintain focus on preventing an unfavourable TB outcome. Patient management and treatment can be optimized by taking into consideration risk factors such as those identified in the present study.

PurposeThe purpose of this study was to assess tuberculosis (TB) treatment outcomes among new smear-positive pulmonary tuberculosis (PTB) patients and identify the risk factors of unsuccessful treatment outcomes in Kepong district, Kuala Lumpur, Malaysia.Design/methodology/approachA retrospective cohort study was conducted using registry-based data from the Tuberculosis Information System (TBIS) between 2014 and 2018. Simple random sampling was used to select 734 males and 380 females from the TBIS registry. Smear-positive PTB patient's sociodemographic, clinical and behavioral characteristics were extracted and analyzed. Logistic regression was used to find the possible independent risk factors for unsuccessful treatment outcomes.FindingsThe treatment success rate was 77.20% (n = 860) which was still below the target set by the WHO (>90%). In total, 254 patients showed an unsuccessful treatment outcome: 106 died, 99 defaulted, 47 not evaluated and 2 showed treatment failure. Unsuccessful treatment outcome was significantly associated with older age, male gender, non-citizen, unemployment and being HIV positive.Originality/valueThe study focuses on all these contributing factors of unsuccessful treatment outcome for a better risk assessment and stratification of TB patients and identify effective surveillance and management strategies to strengthen the control programs of tuberculosis in Kepong district.

Abstract Objective Tuberculosis (TB) is a major cause of morbidity and mortality globally. Despite efforts to eliminate TB in Thailand, the incidence rate has declined slowly. This study aimed to identify the incidence and risk factors of unsuccessful pulmonary TB treatment (failed, died and loss-to- follow up) in a community hospital in Chachoengsao Province, Thailand from 1st January 2013 to 31st December 2019. Results A total of 487 patients were eligible for the study. The incidence of unsuccessful treatment was 21.67/100 population person year. Risk factors of unsuccessful pulmonary TB treatment were unemployment (adjusted hazard ratio (AHR) 3.12, 95%CI 1.41–6.86), HIV co-infection (AHR 2.85, 95%CI 1.25–6.46), previous history of TB (AHR 2.00, 95%CI 1.04–3.81), positive sputum AFB at the end of the intensive phase (AHR 5.66, 95%CI 2.33–13.74), and sputum AFB was not performed at the end of the intensive phase (AHR 18.40, 95%CI 9.85–34.35). This study can be utilized to improve prevention and intervention of TB treatment by strengthening public health system on treatment quality especially TB patient monitoring tools or methods easy for accessing to patients in communities.

Abstract Background: Tuberculosis remains a major global health problem and ranks along with the human immunodeficiency virus (HIV) as a leading cause of mortality worldwide. The aim of this study was to investigate the treatment outcome of tuberculosis, and factors associated with treatment outcome of tuberculosis in TB patients enrolled in Arsi-Robe Hospital, Oromia regional state, South eastern Ethiopia between January 2013 to December 2017. Methods: An Institutional-based retrospective study was conducted in Arsi-Robe Hospital from 2013 to 2017 in study patients who had all forms of TB in DOTS clinic. The predictors of treatment outcomes were analyzed through bivariate and multivariable logistic regression analysis and a P-value < 0.05 were considered statistically significant. Results: Out of the 257 registered TB patients, most of them were males (57.9%), from rural areas (62.6%) and in age of 15-24 category (39.3%). PTB-, PTB+ and EPTB were recorded in 48.2%, 32% and 19.8% of the patients, respectively. Among all cases, 8.6% had TB-HIV co-infection. Among all TB cases, 84.0% had successful treatment outcome. TB patients from urban areas (AOR: 3.34, 95% CI: 1.338.38, P = 0.01), with failure treatment (AOR: 6.66, 95% CI = 1.12- 39.57; P = 0.037) and HIV positive (AOR: 4.92, 95% CI = 1.38-17.51; P = 0.014) had higher odd of unsuccessful treatment outcome of tuberculosis. However, TB patients with PTB+ (AOR: 0.1470, 95% CI = 0.031-0.687; P = 0.015) and EPTB (AOR: 0.194, 95% CI = 0.054-0.688; P = 0.011) had significantly lesser odd of unsuccessful treatment outcome. Conclusions: Being urban resident, treatment failure and HIV positive considerably challenge the treatment outcome of tuberculosis, but being PTB+ and EPTB were associated with higher treatment success rate of TB. Continuous follow-up of patients with unsuccessful treatment outcome of tuberculosis with strengthened implementation of the DOTs strategies are suggested.

The Impact

BackgroundEvidence suggests that social protection policies such as Brazil’s Bolsa Família Programme (BFP), a governmental conditional cash transfer, may play a role in tuberculosis (TB) elimination. However, study limitations hamper conclusions. This paper uses a quasi-experimental approach to more rigorously evaluate the effect of BFP on TB treatment success rate.MethodsPropensity scores were estimated from a complete-case logistic regression using covariates from a linked data set, including the Brazil’s TB notification system (SINAN), linked to the national registry of those in poverty (CadUnico) and the BFP payroll.ResultsThe average effect of treatment on the treated was estimated as the difference in TB treatment success rate between matched groups (ie, the control and exposed patients, n=2167). Patients with TB receiving BFP showed a treatment success rate of 10.58 percentage points higher (95% CI 4.39 to 16.77) than patients with TB not receiving BFP. This association was robust to sensitivity analyses.ConclusionsThis study further confirms a positive relationship between the provision of conditional cash transfers and TB treatment success rate. Further research is needed to understand how to enhance access to social protection so to optimise public health impact.
