Abstract Background The prevalence of infections due to nontuberculous mycobacteria (NTM) is increasing worldwide, yet little is known about the epidemiology and pathophysiology of these ubiquitous environmental organisms. Pulmonary disease due to Mycobacterium avium complex is most prevalent, but many other NTM species can cause disease in virtually any organ system. As NTM becomes an increasingly common cause of morbidity and mortality, more information is needed about the epidemiology of NTM disease. Methods We conducted a retrospective chart review of all patients with cultures that grew NTM at a Midwestern tertiary hospital from 1996 to 2017. Information on demographics, medical history, clinical findings, treatment, and outcome was obtained from medical records of all NTM isolates. American Thoracic Society/Infectious Diseases Society of America criteria were used to define pulmonary NTM infections. Results We identified 1064 NTM isolates, 365 of which met criteria for NTM infection. Pulmonary cases predominated (185 of 365; 50.7%), followed by skin/soft tissue (56 of 365; 15.3%), disseminated (40 of 365; 11%), and lymphatic (28 of 365; 7.7%) disease. Mycobacterium avium complex was the most common species (184 of 365; 50.4%). Individuals aged >50 years were most affected (207 of 365; 56.7%). Common comorbidities included structural lung disease (116 of 365; 31.8%), use of immunosuppressive medications (78 of 365; 21.4%), malignancy (59 of 365; 16.2%), and human immunodeficiency virus (42 of 365; 11.5%). Conclusions This large cohort provides information on the demographics, risk factors, and disease course of patients with pulmonary and extrapulmonary NTM infections. Most patients had medical comorbidities that resulted in anatomic, genetic, or immunologic risk factors for NTM infection. Further population-based studies and increased disease surveillance are warranted to further characterize NTM infection prevalence and trends.

Abstract Background The epidemiology of disseminated Mycobacterium avium complex (DMAC) infection in the United States is changing. Previously most DMAC occurred in adults with advanced AIDS. Since the development of effective antiretroviral therapy, the incidence of DMAC in AIDS has fallen more than 10-fold. Malignancy, immunosuppression, and tumor necrosis factor inhibitors are known risk factors for DMAC. We sought to describe the epidemiology of DMAC disease in HIV seronegative patients in the United States. Methods We performed a retrospective analysis of a commercial database (Explorys Inc., Cleveland, OH). This database contains an aggregate of Electronic Health Record data from 26 major integrated healthcare systems in the United States from 1999 to present. Explorys contains de-identified information from over 50 million patients, 360 hospitals, and over 317,000 providers. We identified a total of 571 persons diagnosed with DMAC, based on Systemized Nomenclature of Medicine-Clinical Terms. We excluded 80 HIV-infected and identified association of the infection with known risk factors. Results Of 570 patients, 491 HIV-uninfected patients with DMAC were studied. Underlying structural pulmonary diseases were COPD and bronchiectasis (51% and 47%, respectively). Two hundred ten patients had concomitant malignancy of which lung cancer was the most frequent (43%). Seventy-nine percent were receiving corticosteroids and 10 patients (2%) were on TNF inhibitors (2%). Conclusion In this study, majority of patients with DMAC are HIV-uninfected. Larger studies should focus on identifying the prevalence and risk factors of DMAC in the post-AIDS era. Disclosures All authors: No reported disclosures.
