How is NTM treated?
Treatment of NTM pulmonary disease varies depending on the species (in some cases subspecies), extent of disease, drug susceptibility results (with limitations), and underlying comorbidities. Regimens require the use of multiple antimicrobial agents that are often associated with clinically significant adverse reactions and must be administered for prolonged periods. Even so, treatment outcomes are often suboptimal, and reinfection with another strain or species is common. In many settings, expert consultation is helpful.
What should be considered when initiating antimicrobial therapy for NTM?
Remarks: The decision to initiate antimicrobial therapy for NTM pulmonary disease should be individualized based on a combination of clinical factors, the infecting species, and individual patient priorities. Any treatment decision should include a discussion with the patient that outlines the potential side effects of antimicrobial therapy, the uncertainties surrounding the benefits of antimicrobial therapy, and the potential for recurrence including reinfection (particularly in the setting of nodular/bronchiectatic disease) [11–13].

In patients with M. xenopi pulmonary disease, we suggest a daily regimen that includes at least three drugs: rifampicin, ethambutol, and either a macrolide and/or a fluoroquinolone (e.g., moxifloxacin) (conditional recommendation, very low certainty in estimates of effect).
What is the diagnostic criteria for NTM?
Diagnosis of NTM pulmonary disease requires the synthesis of clinical, radiographic, and microbiology data. The ATS and IDSA developed a set of criteria to help guide clinicians in determining which patients are likely to have progressive disease [ 4 ]. Unfortunately, the predictive values of these criteria are not well studied, and thus they serve primarily as a guide to clinicians. The laboratory remains a critical component in the diagnosis of NTM pulmonary disease given the many species and variable pathogenicity. Identification of NTM to the species level and in the case of M. abscessus, to the subspecies level, can provide important clinical and epidemiologic information.
How many species are there in the NTM?
NTM represent over 190 species and subspecies ( http://www.bacterio.net/mycobacterium.html ), many of which can produce disease in humans of all ages and can affect both pulmonary and extrapulmonary sites.
Who developed the NTM guideline?
This guideline was developed by a multidisciplinary committee consisting of physicians and researchers with recognized NTM expertise (C.A., E.B., E.C., C.D., D.G., L.G., G.H., J.I., C.L., T.M., K.O., J.S., M.S., E.T., D.W., K.W., R.W.), methodologists (J.L.B. and J.M.I.), and a representative from an NTM nonprofit organization the goal of which is patient support, education, and research in NTM (P.L.). The patient representative was a full participant in each step of the development process but did not vote on specific recommendations. The committee was chaired by C.D. (ATS) and cochaired by C.L. (ERS), E.C. (ESCMID), and R.W. (IDSA), representing their respective societies. The committee worked with a medical librarian (S.K.) who had expertise in evidence synthesis and the guideline development process. All of the members who had potential financial and/or intellectual conflicts recused themselves or were excused by the chairs from discussions related to the recommendation formulation and grading, and voting on recommendations related to the potential conflict. The methodology team conducted systematic reviews and prepared evidence summaries following the GRADE approach [ 1 , 2 ].
Does NTM require antibiotics?
Importantly, just because a patient meets diagnostic criteria for NTM pulmonary disease does not necessarily mean antibiotic treatment is required. A careful assessment of the pathogenicity of the organism, patient’s symptoms, risks and benefits of therapy, the patient’s wish and ability to receive treatment as well as the goals of therapy should be discussed with patients prior to initiating treatment. In some instances, “watchful waiting” may be the preferred course of action.
