“…The World Health Organization [32] and the International Union Against Tuberculosis and Lung Disease provide guidelines [33] for smoking cessation treatment within TB programs. A 2018 systematic review found that interventions provided during TB treatment are feasible and effective in reducing smoking rates among patients [34]. However, considerable variation in treatment components, provider engagement, and time requirements across programs was observed revealing a critical need for further empirical and qualitative research to inform effective integration of cost-effective interventions into standard practice, particularly in low-resource settings.…”

In 2017, more than half of the global burden of incident tuberculosis (TB) came from the Western Pacific region. In Lao People’s Democratic Republic (PDR), the high rates of tobacco use and use of polluting biomass fuels for cooking (e.g., wood, charcoal, crop waste, dung) represent significant risk factors for TB. The purpose of this study was to determine the association between self-reported (1) smoking and TB; and (2) exposure to air pollution (from both cooking fires and environmental tobacco smoke) and TB among adults in Lao PDR. We analyzed data from the 2012 National Adult Tobacco Survey (NATSL) of Lao PDR—a multi-stage stratified cluster sample of 9706 subjects from 2822 households located in all 17 provinces. Utilizing a nationally representative sample and inferential, multivariable methods, we observed a significant increase in odds of self-reported TB among those who smoked tobacco (OR = 1.73, 95% CI = (1.00 to 2.98)). Larger multivariable models identified independent contributions from exposure to tobacco pipes (OR = 21.51, 95% CI = (6.34 to 72.89)) and communal outdoor fires (OR = 2.27, 95% CI = (1.15 to 4.49)). An index measuring combined exposure to smoked tobacco, environmental tobacco smoke in enclosed workspace, indoor cooking fire, trash fires, and other outdoor communal fires also showed a positive association (OR per added exposure = 1.47, 95% CI = (1.14 to 1.89)). The findings of this study underscore the need for multi-sectoral collaboration between tobacco control, environmental health, TB prevention and treatment programs, national authorities, policy makers, civil groups, and the private sector to address the convergence of potential risk factors impacting respiratory health in Lao PDR.

“…In previous studies, smokers were more likely to have UTO than non‐smokers , although we did not find statistically significant differences in our study. However, to improve the overall quality of health of individuals, there is certainly a need to integrate smoking cessation interventions into routine TB services .…”

Objective Tuberculosis (TB) treatment success rates are high in China, but there are still a considerable number of cases who have unfavourable treatment outcomes (UTO). We aimed to determine the proportion of TB patients with UTO and to assess whether baseline characteristics that included glycaemic status [normal fasting blood glucose (FBG), transient hyperglycaemia and diabetes mellitus (DM)] and vitamin D status were associated with UTO. Method Prospective cohort study conducted between November 2015 and July 2016 at six clinics within routine TB services in Jilin province, where persons with TB were consecutively recruited. Data analysis was performed using the chi‐squared test and multivariate logistic regression. Results Of the 306 recruited TB patients, 96 (31.4%) had smear‐positive pulmonary TB, 187 (61.1%) had smear‐negative pulmonary TB and 23 (7.5%) had extrapulmonary TB (EPTB). Of these, 95 (31.1%) had normal blood glucose, 83 (27.1%) had transient hyperglycaemia and 128 (41.8%) had DM. 227 (74.2%) patients had vitamin D deficiency/severe deficiency. There were 125 (40.8%) patients with UTO of whom the majority were lost to follow‐up (57.6%) or not evaluated (28.8%). UTO was significantly associated with smear‐negative pulmonary TB (P = 0.009), EPTB (P < 0.001) and DM (P = 0.007). Conclusion The proportion of TB patients with UTO increased with smear‐negative pulmonary TB, EPTB and DM. TB programmes need to pay more attention to these issues and ensure intensive patient support to those at risk and early detection of DM.

INTRODUCTIONSmoking cessation should be part of tuberculosis (TB) treatment, but a cessation service is not available as part of a routine TB service in most low- and middle-income countries. WHO and The International Union Against Tuberculosis and Lung Disease (The Union) issued a guideline and China implemented a pilot project 5 years ago. This study aimed to determine changes in smoking status among TB patients at 5 years after completion of anti-TB treatment to observe long-term outcome of a smoking cessation project whose baseline characteristics were associated with a relapse of smoking behavior.METHODSA prospective longitudinal study was conducted 5 years after completion of anti-TB treatment to assess changes in patient smoking status against individual baseline data that were entered into a database at the time of TB registration. The patients were tracked by trained village doctors and validated by township health staff. Their smoking status was assessed and entered into the database and analysed.RESULTSOf the 800 TB patients registered at baseline, 650 (81.2%) were tracked. Ninety-one (11.4%) patients died and 59 (7.4%) were lost to follow-up. The rates of remaining non-smoking after 5 years were 82.0%, 63.0%, 49.6%, 43.5% and 30.0%, respectively for non-smokers, ex-smokers, current smokers who received cessation intervention, recent quitters, and current smokers not on a cessation intervention. The odds of smoking relapse were significantly higher for those aged ≥65 years (p=0.003) and registered in Xingguo County (p=0.025).CONCLUSIONSFindings from this study confirmed that non-smokers, ex-smokers and current smokers who received cessation intervention at baseline maintained higher non-smoking rates compared with those who did not receive the intervention. To prevent relapse, intensive cessation support should be given to TB patients aged ≥65 years. TB programme managers need to ensure integration and provision of smoking cessation advice and smoke-free policy in routine TB services.
