“…In contrast, few patients were found to be domiciled in the cities of south-west and north-east region of Korea, where agriculture remains the main occupation. This distribution is in accord with a Japanese observation published in 1983 (18) and a study, which reported that 56% of patients with M. kansasii pulmonary disease were employed in heavy industry (19). …”

“…The clinical characteristics of M. kansasii pulmonary disease patients in the present study were similar to those of previous reports including Korean cases (10, 19, 20). Thus, the present study confirms an association between M. kansasii pulmonary disease with, a male gender, an urban setting, a history of tuberculosis or of another lung disease as a risk factor, a cough as a common symptom, the presence of a cavitary lesion usually in the right upper lobe, and a response to an isoniazid and rifampicin based regimen…”

Mycobacterium kansasii is one of the most common cause of pulmonary diseases due to nontuberculous mycobacteria. We investigated the changing in the number of isolation of M. kansasii and the clinical characteristics of M. kansasii pulmonary disease in Korea. Through searching the database of the Korean Institute of Tuberculosis, we identified the cases of isolated M. kansasii from 1992 to 2002. The number of M. kansasii isolation had increased from once in 1992 to 62 in 2002. Fifteen patients with M. kansasii pulmonary disease were identified during the period January 1997 to December 2002. Twelve patients (80%) were male and fourteen (93%) were from highly industrialized areas. The most common symptom was a cough. Seven patients (47%) had a cavitary lesion and right upper lobe was most commonly involved. Patients responded well to isoniazid and rifampicin based regimens both bacteriologically and radiographically. In conclusion, M. kansasii isolation has increased, especially in highly industrialized areas, as well as other nontuberculous mycobacteria in Korea.

“…All well-defined population-based studies that presented data on the frequency of pulmonary NTM isolation or disease over time have shown increases. [4][5][6][7][8][9] The numerous reports of increasing frequency are consistent with our results and suggest that pulmonary NTM infection is a growing problem. Increases in the frequency of pulmonary NTM throughout the world have not been adequately explained but there are several possible contributing factors.…”

“…All well-defined population-based studies of temporal trends of pulmonary NTM consistently report increases in frequency of 1.5-6-fold over 5-30 years. [4][5][6][7][8][9] The universally observed increases in frequency of pulmonary NTM infection makes this emerging infectious disease relevant to all pulmonary and infectious disease practitioners. The precise magnitude of the problem is not well understood for several reasons.…”

“…Moreover, mining activity is common in the Maranoa-Balonne region (the broader administrative area that includes Yuleba and Clifford). There have been several studies linking M. kansasii to industrial activities such as gold mining and iron manufacture in South Africa, Japan and the former Czechoslovakia [18-20]. In the study by Corbett and Hay, new pulmonary cavitations from M. kansasii were more likely to be found in miners with previous TB scarring or silicosis.…”

A spatial epidemiological analysis of nontuberculous mycobacterial infections in Queensland, Australia

BackgroundThe epidemiology of infections with nontuberculous mycobacteria (NTM) has been changing and the incidence has been increasing in some settings. The main route of transmission to humans is considered to be from the environment. We aimed to describe spatial clusters of cases of NTM infections and to identify associated climatic, environmental and socio-economic variables.MethodsNTM data were obtained from the Queensland Mycobacterial Reference Laboratory for the period 2001–2011. A Bayesian spatial conditional autoregressive model was constructed at the postcode level, with covariates including soil variables, maximum, mean and minimum rainfall and temperature, income (proportion of population earning < $32,000 and < $52,000) and land use category.ResultsSignificant clusters of NTM infection were identified in the central Queensland region overlying the Surat sub-division of the Great Artesian Basin, as well as in the lower North Queensland Local Government Area known as the Whitsunday region. Our models estimated an expected increase of 21% per percentage increase of population earning < $52,000 (95% CI 9–34%) and an expected decrease of 13% for every metre increase of average topsoil depth for risk of Mycobacterium intracellulare infection (95% CI -3 – -22%). There was an estimated increase of 79% per mg/m3 increase of soil bulk density (95% CI 26–156%) and 19% decrease for every percentage increase in population earning < $32,000 for risk of M. kansasii infection (95% CI -3 – -49%).ConclusionsThere were distinct spatial clusters of M. kansasii, M. intracellulare and M. abscessus infections in Queensland, and a number of socio-ecological, economic and environmental factors were found to be associated with NTM infection risk.
