These studies indicate that NTM-PD increases mortality risk at a population level, independent of underlying comorbidities. As shown above, the three studies where MAC lung disease cases were matched with appropriate controls consistently showed an increased risk of mortality for patients with NTM-PD or MAC-PD [21, 26, 27].

RD has received fees for lecturing and consultancy from Insmed and Riemser. Ann Am Thorac Soc. The studies we have identified cover a wide time period (1973–2017) and thus may be influenced by potential variability in NTM diagnosis and treatment over the 44 year period. This is also demonstrated in a funnel plot of data from the selected studies (Fig. I had no symptoms at all - my internist ordered a routine chest x-ray as part of my physical examination and a spot was seen on my lung. 2002;6(7):628–34.

This publication was supported by an educational grant from Insmed Inc. From our list of identified studies, Marras and colleagues found that mortality rates were higher among patients from Ontario who fulfilled the ATS/IDSA disease criteria compared with those who had NTM isolation only (HR = 1.16, 95% CI 1.09–1.24) [21]. Clipboard, Search History, and several other advanced features are temporarily unavailable. Emerg Infect Dis. Am J Respir Crit Care Med. Predictors of better outcome include surgical treatment [12] and nodular or bronchiectatic disease [15]. After adjustment for clinical, microbiological and radiological confounders, independent factors for 5-year mortality were a high Charlson comorbidity index in cases with definite MAC disease (hazard ratio [HR] 1.76) and untreated chronic MAC (HR 3.08), and presence of cavitary lesions in cases with definite MAC disease (HR 1.82) and treated MAC patients (HR 3.91). Get the latest research from NIH: https://www.nih.gov/coronavirus. Black bars indicate fibrocavitary disease, grey bars indicate nodular/bronchiectatic disease. PubMed Central Most of our selected studies do not explicitly identify patients with macrolide-resistant pulmonary disease. Thus, MAC lung disease fulfilling ATS/IDSA criteria is associated with a worse outcome. Yamakawa H, Takayanagi N, Miyahara Y, Ishiguro T, Kanauchi T, Hoshi T, Yanagisawa T, Sugita Y.

Five-year all-cause overall mortality among the 78 patients with definite MAC disease (including treated and untreated chronic MAC patients) was 25.6%. 2017;17(1):436. one with nontuberculous mycobacteria or NTM, caused by Mycobacterium avium complex (MAC), which is made of two Mycobacterium species, M. avium and M. intracellulare. We performed a systematic review of the published literature on five-year all-cause mortality in patients with MAC lung disease, and pooled the mortality rates to give an overall estimate of five-year mortality from these studies. The most common type of nontuberculous mycobacterial lung infection that causes pulmonary disease in the United States are due to the group of bacteria in the M. avium complex (MAC).

Heterogeneity in reported mortality rates was quantified in terms of the Q- and I2-statistics. This is challenging for the field as a whole, and further prospective studies of mortality in MAC-PD patients, which could support identification of additional prognostic factors, are warranted. In other words, a MAC … American Thoracic Society/Infectious Diseases Society of America, The Research Committee of the British Thoracic Society, Nontuberculous mycobacteria pulmonary disease, Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Patients with cavitary lesions require immediate treatment for sputum culture conversion and to improve their chances of survival. A number of patient groups have been associated with increased risk of pulmonary MAC. Johnson MM, Odell JA. Similarly, five-year age-adjusted mortality rates were slightly higher for patients meeting (28.7/1000) versus not meeting (23.4/1000) ATS/IDSA criteria, respectively, in the report by Novosad identified in our analysis [23]. This is much higher than the pooled estimate from our analysis indicating that macrolide resistance increases mortality risk, and should be specifically identified in future studies. This demonstrated that patients with fibrocavitary disease have a substantially greater risk of death compared with nodular disease (Fig. Most NTM infections are due to the Mycobacterium avium complex It comprises various mycobacterial species, including M. intracellulare, M. avium (which has four subspecies), and several other less frequently isolated species including M. chimaera [5, 6].

Fleshner and colleagues also documented pulmonary hypertension as a risk factor for mortality (aHR 2.1, 95% CI 0.9–5.1), although this was not significant following adjustment for fibrocavitary disease; importantly, individual NTM species were not significantly associated with mortality, suggesting similar risks for each NTM species identified in the study [28]. This is a lung condition my wife apparently caught in Nevada. Manage cookies/Do not sell my data we use in the preference centre. This is a concern, as recent work from Korea reported a five-year mortality of 47.1% (95% CI 24.0–70.1) in patients with macrolide-resistant MAC [31]. Auchuleta et al.

However, it is also seen frequently in otherwise healthy patients, with a predilection for older women who deliberately suppress the cough reflex (Lady Windermere syndrome) 1-3. Thus, the impact of MAC lung disease on mortality at a population level is more appropriately reflected in studies using matched control groups. identified an even greater mortality risk (HR 3.64, 95% CI 2.28–5.77) and a mortality after 39 months follow-up of 22.4% for NTM-PD patients versus 6.0% for control patients [27]. Substantial heterogeneity in study characteristics was found, with male sex, presence of cavitary disease and high comorbidity levels predicting worse survival outcomes. 2017;49(2):1601855. | Flow chart describing the selection of studies and data sets included in the analysis.

It will reduce my lung function 10-15%, but other than the MAC, I am in very good health. The analysis demonstrated that patients in Asian studies tended to have a lower five-year mortality (19, 95% CI 14–23%) compared with Europe (35, 95% CI 27–43%) and North America (33, 95% CI 32–35%). Pooling data from all 17 data sets using a random effects model, the overall estimate of five-year all-cause mortality was 27% (95% CI 21.3–33.0%). BMJ. Factors that affect sputum conversion and treatment outcome in patients with Mycobacterium avium-intracellulare complex pulmonary disease.
