However MAI infection may also occur in patients without predisposing lung disease or demonstrable immunodeficiency. Mycobacterium avium-intracellulare infection MAI is an atypical mycobacterial infection ie.
One with nontuberculous mycobacteria or NTM caused by Mycobacterium avium complex MAC which is made of two Mycobacterium species M.
Pulmonary mai mycobacterium avium intracellulare infection. Pulmonary infection with Mycobacterium avium-intracellulare MAI a nontuberculous mycobacteria usually occurs in subjects with damaged lungs such as those afflicted with pulmonary tuberculosis chronic obstructive pulmonary disease COPD bronchiectasis and the lungs of heavy smokers 1 2 or in persons with immunodeficiency such as AIDS. To clarify the structure and function of the airways in Mycobacterium avium-intracellulare MAI infection we performed pulmonary function tests and high-resolution computed tomography HRCT of the thorax in female patients 61 - 9 yr of age n 12 with pulmonary MAI infection without predisposing lung disease and compared their data with those of normal female volunteers 54 - 8 yr of age n 9. Mycobacterium avium complex MAC infections are caused by two types of bacteria.
Mycobacterium avium and Mycobacterium intracellulare. These bacteria are found in many places including water fresh or salt household dust and soil. MAC bacteria get into the body when the bacteria are inhaled into the lungs or swallowed.
Mycobacterium avium complex MAC also known as mycobacterium avium-intracellulare MAI consists of two mycobacterium species M avium and M intracellulare. Although MAC isolates can be identified as M avium or M intracellulare by molecular techniques there is no prognostic or treatment advantage for doing so. Mycobacterium avium-intracellulare pulmonary infection complicated by cutaneous leukocytoclastic vasculitis in a woman with anorexia nervosa.
Mycobacterium avium complex pulmonary disease macmai andor bronchiectasis. I found only 1 thread on mycobacterium accidently under the catagory Lungs. Im hoping by starting a subject matter directly related to MYCOBACTERIUM AVIUM COMPLEX PULMONARY DISEASE MACMAI I may find others out there.
The rising incidence of pulmonary Mycobacterium avium-intracellulare complex MAI infection is unexplained but parallels the growing world-wide epidemic of allergic disease. We hypothesized an association between pulmonary MAI infection and Th2-type immune responses as. Members of Mycobacterium avium complex MAC are the most common pulmonary NTM pathogens in almost all regions of the world.
The three predominate species to cause human disease among the twelve species within the complex are Mycobacterium avium Mycobacterium intracellulare and Mycobacterium chimaera 12. To predict the natural history of pulmonary Mycobacterium avium-intracellulare MAI infection with nodular bronchiectasis we retrospectively evaluated clinical manifestations laboratory data and bronchoalveolar lavage fluid BALF findings in 57 patients. The patients received follow-up chest co.
Pulmonary Infection of Mycobacterium avium-intracellulare Complex with Simultaneous Organizing Pneumonia Kunio Hamada1 Sonoko Nagai2 Yoshikazu Hara3 Toyohiro Hirai2 and Michiaki Mishima2 Abstract A 67-year-old woman presented high-grade fever and dyspnea. Sputum culture confirmed Mycobacterium avium-intracellulare complex MAC. Pulmonary Mycobacterium avium-intracellulare MAI infec-tion usually occurs in patients with damaged lungs including those with chronic obstructive lung disease COPD pulmo-nary tuberculosis bronchiectasis or pneumonoconiosis 13.
However MAI infection may also occur in patients without predisposing lung disease or demonstrable immunodeficiency. To compare the computed tomographic CT findings of tuberculosis and Mycobacterium avium-intracellulare MAI infection in immunocompetent patients. Seventy-seven consecutive immunocompetent patients with culture-proved pulmonary mycobacterial infection 45 with pulmonary tuberculosis 32 with MAI underwent thin-section CT.
Mycobacterium avium and intracellulare MAI is an acid-fast atypical mycobacterium complex that is ubiquitous. The respiratory tract is the most common site for acquiring infection which is usually inapparent. MAI infection can cause chronic pulmonary disease lymphadenitis and disseminated disease especially in immunodeficient patients.
Of interest MAI infection has been seen with frequency in elderly woman who appear to have no predisposing conditions. Mycobacterium avium-intracellulare infection MAI is an atypical mycobacterial infection ie. One with nontuberculous mycobacteria or NTM caused by Mycobacterium avium complex MAC which is made of two Mycobacterium species M.
