BACKGROUND AND PURPOSE Population study on relationship between nontuberculous mycobacterial (NTM) infection and respiratory failure (RF) is limited. This study evaluated the RF risk, including acute respiratory failure (ARF), chronic respiratory failure (CRF) and ARF on CRF, in patients with NTM infection in Taiwan. METHODS We used the National Health Insurance Research Database of Taiwan to...

Nontuberculous mycobacteria (NTM)-lung disease (LD) is an increasing health problem worldwide. The diagnosis of this disease remains difficult, however the application of placenta growth factor (PlGF) and vascular endothelial growth factor (VEGF) has not yet been studied. We screened patients with Mycobacterium avium complex or M. abscessus isolated from sputum, and enrolled 32 patients with NT...

With a surprising predictability, most studies and reviews addressing therapy for nontuberculous mycobacterial (NTM) lung disease either start or end by mentioning the paucity of data from randomized and controlled trials. That is a legitimate criticism for NTM lung disease therapy, but it also somehow seems to influence attitudes toward all aspects of NTM investigation. Certainly the study of ...

Clinical relevance of nontuberculous mycobacteria (NTM) isolated from 180 chronically ill patients and 385 healthy controls in Zambia was evaluated to examine the contribution of these isolates to tuberculosis (TB)-like disease. The proportion of NTM-positive sputum samples was significantly higher in the patient group than in controls; 11% and 6%, respectively (p<0.05). NTM-associated lung dis...

BACKGROUND The significance of nontuberculous mycobacteria (NTM) isolated from a patient during therapy for pulmonary tuberculosis (TB) is uncertain. We investigated the frequency and clinical significance of NTM isolated from patients receiving anti-TB treatment. METHODS We conducted a retrospective cohort study of all patients with culture-confirmed pulmonary TB, and identified patients wit...

INTRODUCTION The infections due to Non-Tuberculosis Mycobacteria (NTM) are becoming an important health problem in many countries in the world. Globally, an increase in NTM infections has been reported from many countries around the world. However, limited information is available about the prevalence of NTM infections in Iran. MATERIAL AND METHODS The data of the prevalence of NTM infections...

A review of 20 studies and 14 case reports published in a recent issue of the journal from 14 provinces in Iran on clinical and environmental isolates of nontuberculous mycobacteria (NTM) showed M. fortuitum (229/997; 23%) as the most prevalent species from 1992 to 2014 [1]. The majority of NTM were collected from respiratory samples. The primary method of NTM detection was by culture using the...

The prevalence of lung disease due to infections with nontuberculous mycobacteria (NTM) has been increasing and surpassed tuberculosis (TB) in some countries. Treatment outcomes are often unsatisfactory, highlighting an urgent need for new anti-NTM medications. Although NTM in general do not respond well to TB specific drugs, the similarities between NTM and Mycobacterium tuberculosis at the mo...

Non-tuberculous mycobacterium (NTM) account for 13% of cystic fibrosis (CF)-related respiratory infections and present a major therapeutic challenge. There is increasing evidence to suggest an adverse prognostic significance of NTM, particularly for Mycobacterium abscessus. A recent large retrospective study of 1216 patients with CF found that growths of NTM were associated with progressive det...

BACKGROUND Non-tuberculous mycobacteria (NTM) can cause pulmonary infection and disease especially among people living with HIV (PLHIV). PLHIV with NTM disease may clinically present with one of the four symptoms consistent with tuberculosis (TB). We describe the prevalence of NTM and Mycobacterium tuberculosis complex (MTBC) isolated among PLHIV who presented for HIV care and treatment. METH...
