Background: Of the 9.2 million new TB cases occurring each year, about 10% are in children. Because childhood TB is usually non-infectious and non-fatal, national programs do not prioritize childhood TB diagnosis and treatment. We reviewed data from a demonstration project to learn more about the epidemiology of childhood TB in Thailand.
BackgroundThe World Health Organization (WHO) recommends that tuberculosis (TB) patients receive directly observed therapy (DOT). Randomized controlled trials have not consistently shown that this practice improves TB treatment success rates. In Thailand, one of 22 WHO-designated high burden TB countries, patients may have TB treatment observed by a health care worker (HCW), family member, or no one. We studied whether DOT improved TB treatment outcomes in a prospective, observational cohort.Methods and FindingsWe prospectively collected epidemiologic data about TB patients treated at public and private facilities in four provinces in Thailand and the national infectious diseases hospital from 2004–2006. Public health staff recorded the type of observed therapy that patients received during the first two months of TB treatment. We limited our analysis to pulmonary TB patients never previously treated for TB and not known to have multidrug-resistant TB. We analyzed the proportion of patients still on treatment at the end of two months and with treatment success at the end of treatment according to DOT type. We used propensity score analysis to control for factors associated with DOT and treatment outcome. Of 8,031 patients eligible for analysis, 24% received HCW DOT, 59% family DOT, and 18% self-administered therapy (SAT). Smear-positive TB was diagnosed in 63%, and 21% were HIV-infected. Of patients either on treatment or that defaulted at two months, 1601/1636 (98%) patients that received HCW DOT remained on treatment at two months compared with 1096/1268 (86%) patients that received SAT (adjusted OR [aOR] 3.8; 95% confidence interval [CI] 2.4–6.0) and 3782/3987 (95%) patients that received family DOT (aOR 2.1; CI, 1.4–3.1). Of patients that had treatment success or that defaulted at the end of treatment, 1369/1477 (93%) patients that received HCW DOT completed treatment compared with 744/1074 (69%) patients that received SAT (aOR 3.3; CI, 2.4–4.5) and 3130/3529 (89%) patients that received family DOT (aOR 1.5; 1.2–1.9). The benefit of HCW DOT compared with SAT was similar, but smaller, when comparing patients with treatment success to those with death, default, or failure.ConclusionsIn Thailand, two months of DOT was associated with lower odds of default during treatment. The magnitude of benefit was greater for DOT provided by a HCW compared with a family member. Thailand should consider increasing its use of HCW DOT during TB treatment.
Purpose-The purpose of this paper is to understand the pattern and perception of alcohol drinking among the Lahu people in northern Thailand. Design/methodology/approach-A qualitative method was used to elicit information on the patterns and perceptions of alcohol drinking amongst the Lahu tribespeople. Question guidelines had been developed from literature reviews and approved by three experts in the field of public health and alcohol studies. A total of 21 participants of different ages and sexes from 3 separate Lahu villages were invited to provide information. All interviews were taped and transcribed before analysis. A content analysis was used. Findings-Lahu people begin alcohol consumption at an average of 12 years, with males usually beginning before females of the same age. Consuming alcohol is perceived to be a sign of adulthood and is also used as a means of gaining social acceptance from others in the community. Alcohol is consumed throughout the year with young and old, male and females, describing varied reasons for drinking. Income, parental behavior,
Summaryobjectives In countries with both TB and human immunodeficiency virus (HIV) epidemics, HIV is known to be the most powerful risk factor for death during tuberculosis (TB) treatment. Few recent studies have evaluated risk factors for death among HIV-uninfected TB patients in these countries. We analysed data from a multi-province demonstration project in Thailand to answer this question.method We prospectively collected data from HIV-uninfected TB patients treated for TB in four provinces and the national infectious diseases hospital in Thailand from [2004][2005][2006]. Standard WHO definitions were used to classify treatment outcomes. We used log-binomial multivariate regression to calculate adjusted relative risk (aRR) and 95% confidence intervals (CI) for factors associated with death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
