Introduction: The isoniazid-resistant TB poses a threat to TB control efforts. Zimbabwe, one of the high TB burden countries, has not explored the burden of isoniazid resistant TB. Hence among all bacteriologically-confirmed TB patients diagnosed in Bulawayo City during March 2017 and December 2018, we aimed to assess the proportion with isoniazid resistant TB and associated factors. Also, we aimed to describe the TB treatment outcomes. Methodology: A cohort study involving routinely collected data by the National TB Reference Laboratory (NTBRL) in Bulawayo City and National TB programme of Zimbabwe. The percentage with 95% confidence interval (CI) was used to express the proportion with isoniazid-resistant TB. The modified Poisson regression was used to assess the association of demographic and clinical characteristics with isoniazid mono-resistant TB. Results: Of 2160 bacteriologically-confirmed TB patients, 1612 (74.6%) had their sputum received at the NTBRL and 743 (46.1%) had culture growth. Among those with culture growth, 34 (4.6%, 95% CI: 3.5-6.7) had isoniazid mono-resistant TB, 25 (3.3%, 95% CI: 2.2-4.9) had MDR-TB. Thus, 59 (7.9%, 95% CI: 6.1-10.1) had isoniazid-resistant TB. Children < 15 years had a higher prevalence of isoniazid mono-resistant TB (aPR= 3.93; 95% CI: 1.24-12.45). Among those with rifampicin sensitive TB, patients with isoniazid-sensitive TB had higher favourable treatment outcomes compared to those with isoniazid-resistant TB (86.3% versus 75.5%, p = 0.039). Conclusions: The prevalence of isoniazid-resistant TB was low compared to neighbouring countries with high burden of TB-HIV. However, Zimbabwe should consider reviewing treatment guidelines for isoniazid mono-resistant TB due to the observed poor treatment outcomes.

The Impact

Alcohol use is associated with increased risk of developing tuberculosis (TB) disease, yet the impact of alcohol use on TB treatment outcomes has not been summarized. We aimed to quantitatively review evidence of the relationship between alcohol use and poor TB treatment outcomes. We conducted a systematic review of PubMed, EMBASE, and Web of Science (January 1980–May 2018). We categorized studies as having a high- or low-quality alcohol use definition and examined poor treatment outcomes individually and as two aggregated definitions (i.e., including or excluding loss to follow-up [LTFU]). We analyzed drug-susceptible (DS-) and multidrug-resistant (MDR-) TB studies separately. Our systematic review yielded 111 studies reporting alcohol use as a predictor of DS- and MDR-TB treatment outcomes. Alcohol use was associated with increased odds of poor treatment outcomes (i.e., death, treatment failure, and LTFU) in DS (OR 1.99, 95% CI 1.57–2.51) and MDR-TB studies (OR 2.00, 95% CI 1.73–2.32). This association persisted for aggregated poor treatment outcomes excluding LTFU, each individual poor outcome, and across sub-group and sensitivity analyses. Only 19% of studies used high-quality alcohol definitions. Alcohol use significantly increased the risk of poor treatment outcomes in both DS- and MDR-TB patients. This study highlights the need for improved assessment of alcohol use in TB outcomes research and potentially modified treatment guidelines for TB patients who consume alcohol.

ABSTRACT Introduction: Multi drug resistant-TB (MDR-TB) threatens global TB control and is a major public health concern in several countries. The present study was undertaken to detect the epidemiological correlates and treatment outcomes among patients with MDR-TB previously or currently admitted in Department of Respiratory Medicine and Pulmonary and Critical Medicine, KGMU, Lucknow. Material & Methods: This retrospective study included 2370 TB patients admitted in the Department of Respiratory Medicine and Pulmonary and Critical Medicine, KGMU, Lucknow between years 2012 to 2015. Treatment outcomes were observed. SPSS software was used for data analysis. Results: The total number of MDR-TB cases enrolled were 2370. There were 772 (32.6%) males (95% CI: 30.7 % -34.5%) and 1598 (67.4%) females (95% CI: 65.5% -69.3%) registered for MDR-TB treatment. The treatment outcomes were as follows: majority (77.1%) were under treatment, 279 (11.8%) patients were declared cured, 10 (0.4%) were failure cases, while 64 (2.7%) were defaulters, 149 (6.3%) had died and 41(1.7%) were transferred out. Conclusion: Emergence of MDR-TB has the potential to be a serious public health problem in Northern India and this necessitates strengthening of TB control and improved continuous monitoring of therapy.

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.

Poor Treatment Outcome

Abstract Background: Multidrug resistant tuberculosis (MDR-TB) remains a serious public health problem with poor treatment outcomes. Predictors of poor outcomes vary in different regions. Vietnam is among the top 30 high burden of MDR-TB countries. We describe demographic characteristics and identify risk factors for poor outcome among patients with MDR-TB in Ho Chi Minh City (HCMC), the most populous city in Vietnam.Methods: This retrospective study included 2,266 patients who initiated MDR-TB treatment between 2011-2015 in HCMC. Treatment outcomes were available for 2,240 patients. Data was collected from standardized paper-based treatment cards and electronic records. A Kruskal Wallis test was used to assess changes in median age and body mass index (BMI) over time, and a Wilcoxon test was used to compare the median BMI of patients with and without diabetes mellitus. Chi squared test was used to compare categorical variables. Multivariate logistic regression with multiple imputation for missing data was used to identify risk factors for poor outcomes. Statistical analysis was performed using R program.Results: Among 2,266 eligible cases, 60.2% had failed on a category I or II treatment regimen, 57.7% were underweight, 30.2% had diabetes mellitus and 9.6% were HIV positive. The notification rate increased 24.7% from 2011-2015. The treatment success rate was 73.3%. Risk factors for poor treatment outcome included HIV co-infection (adjusted odds ratio (aOR): 2.94), advanced age (aOR: 1.45 for every increase of 5 years for patients 60 years or older), having history of MDR-TB treatment (aOR: 5.53), sputum smear grade scanty or 1+ (aOR: 1.47), smear grade 2+ or 3+ (aOR: 2.06), low BMI (aOR: 0.83 for every increase of 1kg/m2 of BMI for patients with BMI<21).Conclusion: The number of patients diagnosed with MDR-TB in HCMC increased by almost a quarter between 2011-2015. Patients with HIV, high smear grade, malnutrition or a history of previous MDR-TB treatment are at greatest risk of poor treatment outcome.

Abstract Background During 2009–2013, Xpert MTB/RIF testing was decentralized in Tanzania. Standardized treatment of multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) was centralized at the Kibong’oto Infectious Diseases Hospital. Initially, Xpert MTB/RIF results were confirmed and complemented with phenotypic drug susceptibility testing before MDR-TB treatment was started. Since 2013, the decision to start MDR-TB treatment in patients with RR-TB relied on Xpert MTB/RIF results. Methods A retrospective cohort study of predictors of unsuccessful treatment outcomes (including death, lost to follow-up and treatment failure) was carried out. Results During the study period, 201 patients started MDR-TB treatment. The number of patients starting MDR-TB treatment increased over time. Out of 201 patients, 48 (23.9%) had an unsuccessful treatment outcome. The median time between sample collection and MDR-TB treatment initiation was reduced from 155 d (IQR 40–228) in the 2009–2012 period to 26 d (IQR 13–64) in 2013. Patients who started MDR-TB treatment in 2013 were more likely (adjusted OR 2.3; 95% CI 1.1–4.7; p=0.02) to have an unsuccessful treatment outcome. Conclusions Xpert MTB/RIF testing increased enrolment on MDR-TB treatment. Reliance on Xpert MTB/RIF results to start MDR-TB treatment reduced time to treatment. However, treatment outcomes did not improve.

Diabetes and undernutrition are common risk factors for tuberculosis (TB), associated with poor treatment outcomes and exacerbated by TB. Limited data exist describing patterns and risk factors of multiple comorbidities in persons with TB. Nine-hundred participants (69.6% male) were enrolled in the Starting Anti-TB Treatment (St-ATT) cohort, including 133 (14.8%) initiating treatment for multi-drug resistant TB (MDR-TB). Comorbidities were defined as: diabetes, HbA1c ≥6.5% and/or on medication; hypertension, systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg and/or on medication; anaemia (moderate/severe), haemoglobin <11g/dL; and, undernutrition (moderate/severe) body-mass-index <17 kg/m2. The most common comorbidities were undernutrition 23.4% (210/899), diabetes 22.5% (199/881), hypertension 19.0% (164/864) and anaemia 13.5% (121/899). Fifty-eight percent had ≥1 comorbid condition (496/847), with 17.1% having ≥2; most frequently diabetes and hypertension (N = 57, 6.7%). Just over half of diabetes (54.8%) and hypertension (54.9%) was previously undiagnosed. Poor glycemic control in those on medication (HbA1c≥8.0%) was common (N = 50/73, 68.5%). MDR-TB treatment was associated with increased odds of diabetes (Adjusted odds ratio (AOR) = 2.48, 95% CI: 1.55–3.95); but decreased odds of hypertension (AOR = 0.55, 95% CI: 0.39–0.78). HIV infection was only associated with anaemia (AOR = 4.51, 95% CI: 1.01–20.1). Previous TB treatment was associated with moderate/severe undernutrition (AOR = 1.98, 95% CI: 1.40–2.80), as was duration of TB-symptoms before starting treatment and household food insecurity. No associations for sex, alcohol or tobacco use were observed. MDR-TB treatment was marginally associated with having ≥2 comorbidities (OR = 1.52, 95% CI: 0.97–2.39). TB treatment programmes should plan for large proportions of persons requiring diagnosis and management of comorbidities with the potential to adversely affect TB treatment outcomes and quality of life. Dietary advice and nutritional management are components of comprehensive care for the above conditions as well as TB and should be included in planning of patient-centred services.

Background Public–private mix (PPM) programs on tuberculosis (TB) have a critical role in engaging and integrating the private sector into the national TB control efforts in order to meet the End TB Strategy targets. South Korea’s PPM program can provide important insights on the long-term impact and policy gaps in the development and expansion of PPM as a nationwide program. Methods and findings Healthcare is privatized in South Korea, and a majority (80.3% in 2009) of TB patients sought care in the private sector. Since 2009, South Korea has rapidly expanded its PPM program coverage under the National Health Insurance (NHI) scheme as a formal national program with dedicated PPM nurses managing TB patients in both the private and public sectors. Using the difference in differences (DID) analytic framework, we compared relative changes in TB treatment outcomes—treatment success (TS) and loss to follow-up (LTFU)—in the private and public sector between the 2009 and 2014 TB patient cohorts. Propensity score matching (PSM) using the kernel method was done to adjust for imbalances in the covariates between the 2 population cohorts. The 2009 cohort included 6,195 (63.0% male, 37.0% female; mean age: 42.1) and 27,396 (56.1% male, 43.9% female; mean age: 45.7) TB patients in the public and private sectors, respectively. The 2014 cohort included 2,803 (63.2% male, 36.8% female; mean age: 50.1) and 29,988 (56.5% male, 43.5% female; mean age: 54.7) patients. In both the private and public sectors, the proportion of patients with transfer history decreased (public: 23.8% to 21.7% and private: 20.8% to 17.6%), and bacteriological confirmed disease increased (public: 48.9% to 62.3% and private: 48.8% to 58.1%) in 2014 compared to 2009. After expanding nationwide PPM, absolute TS rates improved by 9.10% (87.5% to 93.4%) and by 13.6% (from 70.3% to 83.9%) in the public and private sectors. Relative to the public, the private saw 4.1% (95% confidence interval [CI] 2.9% to 5.3%, p-value < 0.001) and −8.7% (95% CI −9.7% to −7.7%, p-value <0.001) higher rates of improvement in TS and reduction in LTFU. Treatment outcomes did not improve in patients who experienced at least 1 transfer during their TB treatment. Study limitations include non-longitudinal nature of our original dataset, inability to assess the regional disparities, and verify PPM program’s impact on TB mortality. Conclusions We found that the nationwide scale-up of the PPM program was associated with improvements in TB treatment outcomes in the private sector in South Korea. Centralized financial governance and regulatory mechanisms were integral in facilitating the integration of highly diverse South Korean private sector into the national TB control program and scaling up of the PPM intervention nationwide. However, TB care gaps continued to exist for patients who transferred at least once during their treatment. These programmatic gaps may be improved through reducing administrative hurdles and making programmatic amendments that can help facilitate management TB patients between institutions and healthcare sectors, as well as across administrative regions.

Abstract Background: This work aimed to describe the clinical presentation of TB in patient with DM, to determine the effects of DM on TB treatment outcomes, to identify the effects of TB on glycemic control, and to describe the lipid profile of TB and DM patients. Methods: This prospective cohort study design was conducted. The data were collected from September 2018 to June 2020 using patient interviews, examining the patients, chart review, and collecting blood samples. Binary logistic regression was used to identify the determinants of TB treatment outcomes in the context of DM. Kaplan Meier survival curve was used to see the effects of DM on TB clinical response. Linear regression was used to identify the determinants of the HbA1c level during TB infection. Results: A total of 1092 study participants were included giving for the response rate at 93.81 %. Good TB treatment outcome was observed in 72.5 % of the patients [95 % CI: 69 % - 76 %]. The odds of good TB treatment outcomes were at 75 % lower in the presence of DM (AOR 0.25 [95 % CI: 0.08 – 0.73]). The median time of clinical response in TB and DM patients was 45 days interquartile range (IQR) of 8 days; the median time of clinical response in DM free TB patients was 9 days [IQR 2 days]. TB increased the HbA1c level of DM patients by 1.22 % (B 1.22 [95% CI: 1.11 – 1.34]). In six months period, 60 % of TB and DM patients had got 3 episodes of acute complications. Conclusion: DM significantly decreases the favorable treatment outcome of DOTS. TB predisposed DM patients for bad glycemic control and increased episodes of acute DM complications.
