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 ...

BACKGROUND Nontuberculous mycobacteria (NTM) are considered opportunistic pathogens, and several species of NTM are associated with human diseases that typically involve the pulmonary, skin/soft tissue, or lymphatic systems; such infection may also cause disseminated diseases. Recent studies have reported increasing rates of NTM-induced disease worldwide. METHODS Respiratory samples are being...

Background. Risk factors for non-tuberculous mycobacteria (NTM) lung infections have been well investigated. However, few studies have examined risk factors for NTM in-dwelling vascular catheter (IDVC) infections. Sickle cell anemia is known to affect several aspects of the immune system leading to relative immune deficiency. The purpose of this retrospective nested case-control study is to det...

During the past decades, a growing interest has been raised in evaluating nontuberculous mycobacteria (NTM) in patients with noncystic fibrosis bronchiectasis (NCFBE). This paper reviews several aspects of the correlations between NTM and NCFBE, including pathogenesis, radiological features, diagnosis, and management. Bronchiectasis and NTM lung disease are connected, but which one comes first ...

Limited data are available describing extrapulmonary nontuberculous mycobacteria (NTM) infections in the general population. We describe results from statewide population-based laboratory surveillance in Oregon, USA, during 2007-2012. We defined a case of extrapulmonary NTM infection as >1 isolate from skin/soft tissue, disseminated sites, lymph node, joint, or other sites. The annual incidence...

BACKGROUND The QuantiFERON-TB-Gold Test (QFT) is more specific than the Mantoux skin-test to discriminate between Mycobacterium tuberculosis (MTB) and non-tuberculous mycobacterial (NTM) infections. Here we study the performance of the QFT in patients with NTM disease. METHODS From 2005 to 2011, nationwide patient data on positive NTM cultures (n = 925) were combined with nationwide data on Q...

Neurotrimin (Ntm) together with the limbic system-associated membrane protein (LAMP) and the opioid-binding cell adhesion molecule (OBCAM) comprise the IgLON family of neural cell adhesion molecules. These glycosylphosphatidylinositol (GPI)-anchored proteins are expressed in distinct neuronal systems. In the case of Ntm, its expression pattern suggests a role in the development of thalamocortic...

Nontuberculous mycobacteria (NTM) are a large group of environmental organisms with worldwide distribution, but only a relatively few are known to be pathogenic. Chronic, debilitating lung disease is the most common manifestation of NTM infection, which is often refractory to treatment. The incidence and prevalence of NTM lung disease are increasing in the United States and in many parts of the...

BACKGROUND Non-tuberculous mycobacteria (NTM) infection is an emerging health problem. We present here the Zambia-specific national level data of prevalence, symptomatic, radiological and microbiological characteristics of NTM, using results from a national Tuberculosis (TB) prevalence survey. METHODS This was a cross-sectional study of the prevalence of NTM among adults aged 15 years and abo...
