It was only in the mids, with the development of effective chemotherapy for Mycobacterium tuberculosis and with more widespread culturing of biologic fluids with positive acid-fast smears, that researchers finally accepted that there were persons with tuberculosis-like disease from whom no other pathogens could be isolated 3, 4.

An aminoglycoside should be considered for advanced cavitary disease Substitution of a macrolide for isoniazid had been associated with good outcomes. These recommendations are based on a randomized trial and observational studies. A fluroquinolone can be substituted. These recommendations are based on two randomized clinical trials and observational studies.
Agents typically active in vitro include rifamycins, macrolides, ethambutol, sulfonamides, and susceptible or intermediately susceptible to doxycycline and minocycline. Deep tissue infection, particularly hand infections, may require surgical debridement. These recommendations are based on observational studies.
Recent reports have described in vitro synergy with clofazimine and amikacin. An aminoglycoside should be considered for cavitary disease or the acute infiltrative form of disease. These recommendations are based on two randomized clinical trials, observational studies, and systematic review. Patients should be treated with at least two active drugs to provide more rapid clearance of the mycobacteria from the blood and prevent acquisition of drug resistance.
Drugs with activity that have been studied include the macrolides clarithromycin and azithromycin , rifabutin, ethambutol, and the aminoglycosides. Clarithromycin versus azithromycin: Clarithromycin at mg twice daily is preferred over azithromycin mg daily based on data from a clinical trial showing a higher frequency of elimination of MAC from blood and more rapid clearance. However, azithromycin may be substituted if there are concerns for drug interactions or intolerance. Note: There are drug-drug interactions with the use of clarithromycin and rifabutin in combination.
The rifabutin serum drug concentration increases, and the clarithromycin level decreases. The increased rifabutin level has been associated with uveitis. If the patient is receiving a protease inhibitor, dosage adjustments must be made.
Duration: Patients should be treated for a minimum of 12 months. Therapy should be life-long in patients without immune reconstitution. Airway hygiene should include, at minimum, the use of a flutter or positive expiratory pressure value. The use of immune adjuvants, such as interferon-gamma, remains controversial.
Currently, interferon-gamma should be administered only when patients have documented immunological defects that would be expected to respond to treatment. Expert immunological consultation is advised. Hemoptysis: Patients with SGM pulmonary infections may develop hemoptysis. Concurrent or recurrent infections with other bacteria, such as Pseudomonas aeruginosa, are common.
The decision to treat or not treat varies based on a number of factors, such as the specific species isolated, presence of co-morbidities, extent of disease, and overall goals of therapy. If a drug must be stopped, it is important to identify a substitute drug. In such cases, it is strongly recommended that expert consultation be obtained.
Non-tuberculous Mycobacterial Infections of the Lung - Pulmonology Advisor
Human disease is thought to occur through exposure to environmental sources, although the specific source is often not identified. There have been several reports of isolation of the same species and genotype pattern in home water supplies i. A recent study evaluated the home water supplies of 37 patients with NTM pulmonary disease and reported isolation of the same species and genotype in 7 patients. In most studies, M. The second most common cause varies from study to study with M. However, recent studies have reported that M. Accurate data on the incidence and prevalence of SGM infections are lacking from most countries, because the disease is not reportable.
In a retrospective study of laboratory cultures in Oregon between and , patients were identified who had greater than or equal to 1 NTM isolate. Approximately one-half of the patients met ATS criteria for disease, which gave an annualized prevalence of 7. Pulmonary cases predominated with a rate of 5. Pulmonary disease prevalence was significantly higher in women than men 6. Disease appeared more commonly in urban areas. In a follow-up study, all Oregon residents with greater than or equal to 1 NTM isolate were identified. From a population-based subset, clinical and radiographic information was obtained.
Again, approximately one-half of the patients met ATS microbiologic criteria, giving an overall 2-year period prevalence of 8. The annual prevalence significantly increased from 20 to 47 per , persons 8. Western states had the highest prevalence of cases per , with Hawaii having the highest prevalence of per , persons.

Other high prevalence areas included the Southeastern United States. Khan and colleagues demonstrated that an increase in skin test reactivity to M. Most of the increase was seen in foreign-born persons. Ontario, Canada : The isolation prevalence of all species excluding M. Four Integrated Health Care Delivery Systems in the United States : 28, samples from 7, patients were included in the analysis.
The average annual site-specific prevalence of NTM lung disease ranged from 1. Prevalence was 1. The prevalence of NTM lung disease was increasing significantly at the two sites where trends were studied: 2. Among persons 60 years of age or older, annual prevalence increased from The annual prevalence significantly increased from 20 to 47 per , persons or 8. Pulmonary NTM hospitalizations increased significantly with age among both genders.
Annual prevalence increased significantly among men and women in Florida 3. NTM infections are reportable in Queensland, Australia. The incidence of cases rose from 2. The pattern of disease changed from predominantly cavitary disease in middle-aged men who smoke to fibronodular disease in elderly women. Most of the increase could be attributable to M. Although SGM have been isolated from several different animal species, they are not known to be spread from animals to humans.
Mycobacterial infections (non-tuberculosis)
By far the most common SGM to produce lung disease are those of the M. The other SGM are rare causes of lung disease. SGM are environmental organisms so exposure is common.

- The Dreams of the Chosen (The Deucalion Sequence, Book 3).
- Nontuberculous Mycobacterial Infections;
However, progression to disease is relatively uncommon given the ubiquitous nature of NTM. The pathogenicity of SGM varies widely with some species, such as M. Pulmonary disease commonly occurs in the setting of underlying lung disease, such as cystic fibrosis, non-cystic fibrosis bronchiectasis, chronic obstructive lung disease, prior tuberculosis, pneumoconiosis, alveolar proteinosis, and esophageal disorders.
NTM or inhaled or aspirated from the environment can presumably cause disease due to a lack of normal airway clearance mechanisms. Women with nodular bronchiectasis and NTM pulmonary infections often have a specific morphotype characterized by lean body habitus, scoliosis, pectus excavatum, and mitral valve prolapse. Why these women develop bronchiectasis and NTM infections is unknown. To date, no significant immunological defect has been described. Several immunological defects have been described in patients with disseminated disease.
These include defects in interferon gamma receptors and IL NTM infections can involve organ system, particularly in immunocompromised individuals. A history of lymph node enlargement, particularly cervical enlargement, may be due to NTM infection. Complaints of cutaneous lesions, either singly or multiply, may be due to NTM cutaneous disease or disseminated disease.
The patient should be questioned regarding recent trauma or invasive medical procedures. In the case of M.
