Background: Little is known about the health-related quality of life of Thai people living with chronic obstructive pulmonary disease or about the physiological and psychosocial factors that most affect it.

Diagnosis and management of latent tuberculosis infection in Asia: Review of current status and challenges.

Asia has the highest burden of tuberculosis (TB) and latent TB infection (LTBI) in the world. Optimizing the diagnosis and treatment of LTBI is one of the key strategies for achieving the WHO 'End TB' targets. We report the discussions from the Asia Latent TubERculosis (ALTER) expert panel meeting held in 2018 in Singapore.

Effectiveness of Tuberculosis Screening Technology in the Initiation of Correct Diagnosis of Pulmonary Tuberculosis at a Tertiary Care Hospital in Thailand: Comparative Analysis of Xpert MTB/RIF Versus Sputum AFB Smear.

Pulmonary tuberculosis (PTB) is one of the top 10 causes of mortality worldwide in 2016. Early detection is very important, as it can help early treatment. This study compared 2 separate methods of diagnosing PTB among suspected patients, specifically examining correct diagnosis and the duration of receiving a correct diagnosis.

Genotypic distribution of multidrug-resistant and extensively drug-resistant tuberculosis in northern Thailand.

Background: Multidrug/extensively drug-resistant tuberculosis (M/XDR-TB) is a major public health problem, and early detection is important for preventing its spread. This study aimed to demonstrate the distribution of genetic site mutation associated with drug resistance in M/XDR-TB in the northern Thai population.

Methods: Thirty-four clinical MTB isolates from M/XDR-TB patients in the upper northern region of Thailand, who had been identified for drug susceptibility using the indirect agar proportion method from 2005 to 2012, were examined for genetic site mutations of , , and for isoniazid (INH) drug resistance and for rifampicin (RIF) drug resistance.

FACTORS ASSOCIATED WITH DELAY IN TUBERCULOSIS TREATMENT AT 10 TERTIARY LEVEL CARE HOSPITALS IN THAILAND.

Tuberculosis (TB) is common in Thailand. Delay in initiating tuberculosis treatment is a major public health problem. Delay in treatment can result in more severe diseases, risk for death, and greater risk of tuberculosis transmission in the community.

Bedaquiline in the treatment of multidrug- and extensively drug-resistant tuberculosis.

Bedaquiline, a diarylquinoline, improved cure rates when added to a multidrug-resistant tuberculosis (MDR-TB) treatment regimen in a previous placebo-controlled, phase 2 trial (TMC207-C208; NCT00449644). The current phase 2, multicenter, open-label, single-arm trial (TMC207-C209; NCT00910871) reported here was conducted to confirm the safety and efficacy of bedaquiline.Newly diagnosed or previously treated patients with MDR-TB (including pre-extensively drug-resistant (pre-XDR)-TB or extensively drug-resistant (XDR)-TB) received bedaquiline for 24 weeks with a background regimen of anti-TB drugs continued according to National TB Programme treatment guidelines.

Risk Factors for Multidrug-Resistant Tuberculosis among Patients with Pulmonary Tuberculosis at the Central Chest Institute of Thailand.

There are limited data available on the risk factors for multidrug-resistant tuberculosis (MDR-TB). Therefore, we here conducted a retrospective matched case-control study among adults with pulmonary TB who received treatment at the Central Chest Institute of Thailand (CCIT) between January 2007 and December 2013, in order to determine the risk factors associated with MDR-TB among patients with pulmonary TB. We identified 145 patients with pulmonary MDR-TB (cases) and 145 patients with drug-sensitive pulmonary TB (controls).

Validation of the new COPD assessment test translated into Thai in patients with chronic obstructive pulmonary disease.

Background: The COPD Assessment Test (CAT™) is a new questionnaire that has been developed recently for measuring the COPD patient's health status. It is known to have a good correlation with disease specific health status measured by St. George's Respiratory Questionnaire (SGRQ).

Whole-genome sequencing to establish relapse or re-infection with Mycobacterium tuberculosis: a retrospective observational study.

Background: Recurrence of tuberculosis after treatment makes management difficult and is a key factor for determining treatment efficacy. Two processes can cause recurrence: relapse of the primary infection or re-infection with an exogenous strain. Although re-infection can and does occur, its importance to tuberculosis epidemiology and its biological basis is still debated.
