Serodiagnosis of Mycobacterium avium Complex Disease in Humans: Translational Research from Basic Mycobacteriology to Clinical Medicine.

Serodiagnosis of Mycobacterium avium Complex Disease in Humans: Translational Research from Basic Mycobacteriology to Clinical Medicine. Jpn J Infect Dis. 2014;67(5):329-32 Authors: Kobayashi K Abstract Rapid and accurate diagnosis of infectious diseases, including mycobacterial disease such as tuberculosis (TB) and diseases due to nontuberculous mycobacteria (NTM), is a very important element of global health. The gold standard in diagnosis of mycobacterial diseases remains clinical examination, combined with direct microscopic examination of sputum and culture of bacteria. Culture of slowly growing mycobacteria, including Mycobacterium tuberculosis and NTM (such as M. avium complex: MAC), can take up to 4 to 6 weeks, and in 10-20% of cases the bacillus is not successfully cultivated. Diagnosis of MAC pulmonary disease (MAC-PD) is complicated and time-consuming (usually at least 1 month). I have characterized the nature of MAC antigens and immune responses from the aspect of basic mycobacteriology, and then translated to clinical science. My multicenter study in Japan has demonstrated the usefulness of a serodiagnostic test to determine serum IgA antibodies against mycobacterial glycopeptidolipid (GPL) core antigen for diagnosing MAC-PD within a few hours. To validate in a larger number of patients, at diverse geographic locations, and among other races, the test was also assessed the usefulness internationally in the United States ...
