A retrospective study of factors associated with treatment decision for nontuberculous mycobacterial lung disease in adults without altered systemic immunity.

BMC Infect Dis 2018 Dec 14;18(1):659. Epub 2018 Dec 14.

Département des Maladies infectieuses et tropicales, Hôpital de la Croix-Rousse, Hospices Civils de Lyon, 103, Grande-Rue de la Croix-Rousse, 69317, cedex 04, Lyon, France.

Background: Nontuberculous mycobacteria (NTM) lung diseases are increasingly recognized as chronic opportunistic infections, occurring in individuals with a wide variety of underlying conditions. In the absence of systemic immunodeficiency, decision of NTM lung disease treatment must relies on a careful risk/benefit assessment, given the requirement of long-term administration of multidrug therapies supported by limited evidence. The primary objective was to identify the factors associated with anti-NTM treatment initiation. Read More

Diagnosis of nontuberculous mycobacterial disease in the era of surveillance chest CT scans.

Infection 2018 Dec 8;46(6):861-865. Epub 2018 Oct 8.

Division of Pulmonary, Allergy, Critical Care and Sleep Medicine, University of Miami, Miami, FL, USA.

The radiologic surveillance of smokers with low-dose CT scan has led to a significant surge of radiologic incidental findings, including the detection of early stages of pulmonary infections including nontuberculous mycobacteria (NTM). This causes a state of overdiagnosis and potential overtreatment of NTM lung disease. Here we propose a new approach to NTM pulmonary disease in the era of increased CT scanning. Read More

Double lung transplantation in an HIV-positive patient with Mycobacterium kansasii infection.

Transpl Infect Dis 2019 Feb 3;21(1):e12999. Epub 2018 Oct 3.

Département de Microbiologie médicale et Infectiologie, Centre Hospitalier de l'Université de Montréal, Montréal, Québec, Canada.

Good outcomes with kidney and liver transplantation in HIV-positive patients have led clinicians to recommend lung transplantation in HIV-positive patients based on extrapolated data. Pre-transplant mycobacterial infection is associated with an increased risk of developing new infection or aggravating existing infection, though it does not contraindicate transplantation in non-HIV-infected patients. However, no data exists regarding the outcome of HIV-positive patients with pre-transplant mycobacterial infection. Read More

BMC Health Serv Res 2018 Sep 10;18(1):700. Epub 2018 Sep 10.

Institute for Epidemiology, University Medical Hospital Schleswig-Holstein (Member of the German Center for Lung Research [ARCN]), Kiel, Germany.

Background: Management of nontuberculous mycobacterial lung disease (NTMLD) consists of a long-term multi-drug antibiotic regimen, yet many patients do not achieve culture conversion. We estimated the NTMLD-related direct medical costs in Canada, France, Germany, and the United Kingdom (UK) among refractory patients who were infected with Mycobacterium avium complex (MAC), without concomitant cystic fibrosis, tuberculosis, or HIV.

Methods: We conducted a retrospective observational physician survey of nationally representative samples. Read More

Latent class analysis to define radiological subgroups in pulmonary nontuberculous mycobacterial disease.

BMC Pulm Med 2018 Aug 31;18(1):145. Epub 2018 Aug 31.

National Heart and Lung Institute, Imperial College London, London, UK.

Background: Nontuberculous mycobacterial (NTM) pulmonary disease has conventionally been classified on the basis of radiology into fibrocavitary and nodular-bronchiectatic disease. Whilst being of great clinical utility, this may not capture the full spectrum of radiological appearances present. The aim of this study was to use latent class analysis (LCA) as an unbiased method of grouping subjects with NTM-pulmonary disease based on their CT features and to compare the clinical characteristics of these groups.

Influence of intersegmental plane size and segment division methods on preserved lung volume and function after pulmonary segmentectomy.

Gen Thorac Cardiovasc Surg 2019 Feb 30;67(2):234-238. Epub 2018 Aug 30.

Division of Thoracic Surgery, Department of Surgery, National Hospital Organization Yamaguchi-Ube Medical Center, Ube, Japan.

Objectives: We previously reported that the use of a stapler to divide intersegmental planes did not decrease preserved pulmonary volume or function relative to electrocautery. However, preservation of pulmonary volume or function can be compromised when a stapler is used with larger intersegmental planes. Here, we assessed the correlations between preserved lung volume and pulmonary function after segmentectomy and the size of the intersegmental planes, based on the division method. Read More

complex (MAC) is the most commonly isolated nontuberculous mycobacterial respiratory pathogen worldwide. MAC lung disease is manifested either by fibrocavitary radiographic changes similar to pulmonary tuberculosis or by bronchiectasis with nodular and reticulonodular radiographic changes. This latter form of MAC lung disease, termed "nodular bronchiectatic (NB) MAC lung disease" is the most common form of MAC lung disease in the United States. Read More

Radiology of Chronic Cavitary Infections.

J Thorac Imaging 2018 Sep;33(5):334-343

Pulmonary Section, Denver Veterans Affairs Medical Center.

Chronic cavitary lung disease is an uncommon manifestation of pulmonary infection, and is a pattern which worldwide is most commonly caused by reactivation tuberculosis. Other organisms, however, can cause similar radiologic patterns. Endemic fungi have long been recognized as potential causes of this pattern in North and South America, but the frequency with which these diseases present with chronic cavities in North America is relatively small.

Chronic Cavitary Infections Other than Tuberculosis: Clinical Aspects.

J Thorac Imaging 2018 Sep;33(5):322-333

Pulmonary Section, Denver Veterans Affairs Medical Center.

Lung cavitation may be due to infectious or noninfectious pathologic processes. The latter category includes nonmalignant conditions, such as granulomatosis with polyangiitis, and malignant conditions, such as squamous cell carcinoma of the lung. Infectious etiologies that produce lung cavitation usually cause chronic illness, although some, particularly pyogenic bacteria, may produce acute cavitary disease. Read More

Bronchial wash culture is less valuable in patients suspected to have nontuberculous mycobacteria lung disease for bilateral bronchiectasis with nodules.

Int J Mycobacteriol 2018 Apr-Jun;7(2):178-182

Department of Pulmonology, Yokohama City University Graduate School of Medicine, Yokohama, Japan.

Backgrounds: Bronchiectasis (BE) with nodules on chest computed tomography (CT) is one of the radiological findings of nontuberculous mycobacteria (NTM) lung disease. However, the NTM lung disease is not diagnosed in some patients who undergo bronchoscopy, though their radiological findings show BE with nodules. We need the indicator to distinguish the patients who would not be given the diagnosis of NTM lung disease with bronchoscopy. Read More

Nontuberculous mycobacterial lung disease in a patient with COPD and bronchiectasis, with radiological signs of lung tumor.

Adv Respir Med 2018 ;86(1):17-22

Instytut Grużicy i Chorób Płuc, UL. Płocka 26, 01-138 Warszawa, Poland.

Mycobacterial lung disease is caused by nontuberculous mycobacteria (NTM), also known as atypical mycobacteria. NTM are widely distributed in the environment, particularly in soil and water; they may colonize the airways, gastrointestinal tract and genitourinary system, without the apparent signs of disease. Nevertheless, in some risk groups such as patients with chronic lung diseases or with immunodeficiency, mycobacterial lung disease is identified. Read More

Causative species of nontuberculous mycobacterial lung disease and comparative investigation on clinical features of Mycobacterium abscessus complex disease: A retrospective analysis for two major hospitals in a subtropical region of Japan.

PLoS One 2017 23;12(10):e0186826. Epub 2017 Oct 23.

Department of Respiratory Medicine, Okinawa Chubu Hospital, Okinawa, Japan.

Nontuberculous mycobacteria (NTM) lung disease is increasing globally. Although the etiological epidemiology of NTM is different across regions, Mycobacterium avium complex (MAC) is the leading cause of NTM lung disease in most countries, including mainland Japan. Okinawa is located in the southernmost region of Japan and is the only prefecture categorized as a subtropical region in Japan, it is therefore likely the etiological epidemiology of NTM lung disease is different from mainland Japan.

Pathology of pulmonary tuberculosis and non-tuberculous mycobacterial lung disease: Facts, misconceptions, and practical tips for pathologists.

Semin Diagn Pathol 2017 Nov 7;34(6):518-529. Epub 2017 Jun 7.

Department of Pathology, Cleveland Clinic Robert J. Tomsich Pathology and Laboratory Medicine Institute, 9500 Euclid Avenue/L25, Cleveland, OH 44195, United States. Electronic address:

Most pathologists are familiar with the microscopic features of tuberculosis and the need to examine special stains for acid-fast bacteria (AFB) in cases of granulomatous lung disease. However, misconceptions do exist, including the concept that finding AFB in "caseating granulomas" confirms the diagnosis of tuberculosis. This dogma is attributable to the high prevalence of tuberculosis in many countries, as well as unfamiliarity with the microscopic spectrum of non-tuberculous mycobacterial lung disease. Read More
