[SERODIAGNOSIS OF THE MYCOBACTERIUM AVIUM COMPLEX BY USING IgA ANTIBODIES FOR THE GLYCOPEPTIDOLIPID CORE ANTIGEN].

Serodiagnosis of Mycobacterium avium complex and Mycobacterium abscessus complex pulmonary disease by use of IgA antibodies to glycopeptidolipid core antigen.

An enzyme immunoassay kit that detects serum IgA antibody reacting to glycopeptidolipid core antigen derived from Mycobacterium avium complex (MAC) was not useful for differentiating MAC pulmonary disease (PD) from Mycobacterium abscessus complex PD (MAB-PD). However, this assay could be useful for differentiating MAC- and MAB-PD from pulmonary tuberculosis. (This study has been registered at C...

Diagnostic test accuracy of anti-glycopeptidolipid-core IgA antibodies for Mycobacterium avium complex pulmonary disease: systematic review and meta-analysis

Currently, an anti-glycopeptidolipid (GPL)-core IgA antibody assay kit for diagnosing Mycobacterium avium complex (MAC) is commercially available. We conducted this systematic review and meta-analysis to reveal the precise diagnostic accuracy of anti-GPL-core IgA antibodies for MAC pulmonary disease (MAC-PD). We systematically searched reports that could provide data for both sensitivity and sp...

Serodiagnosis of Mycobacterium avium complex pulmonary disease in rheumatoid arthritis.

BACKGROUND Mycobacterium avium complex (MAC) pulmonary disease (PD) is often difficult and complicated to diagnose or to discriminate from follicular bronchitis, bronchiectasis, or other conditions associated with rheumatoid arthritis (RA) lung in the clinical setting. OBJECTIVE We investigated whether a serologic test for anti-glycopeptidolipid (GPL) antibody was useful for distinguishing MA...

SERA FROM SYPIllLI ATIC PATIENTS CROSS REACT WITH SPECIFIC GLYCOPEPTIDOLIPID AND WHOLE LIPID EXTRACT OF MYCOBACTERIUM AVIUM COMPLEX IN AN ANTICARDI OLIPIN ANTIBODY TEST

Serodiagnosis of pulmonary disease due to Mycobacterium avium complex with an enzyme immunoassay that uses a mixture of glycopeptidolipid antigens.

It is difficult to distinguish pulmonary disease due to Mycobacterium avium complex (MAC) from that due to other mycobacteria, such as Mycobacterium tuberculosis and Mycobacterium kansasii. We developed an enzyme immunoassay (EIA) for diagnosis of MAC pulmonary diseases that uses glycopeptidolipid (GPL) antigens specific for MAC, and we used it for diagnosis in immunocompetent patients. The mea...
