    Kekkaku 2016 Feb;91(2):75-82
    In the advanced stages of mycobacterial infections, host immune systems tend to change from a Th1-type to Th2-type immune response, resulting in the abrogation of Th1 cell- and macrophage-mediated antimicrobial host protective immunity. Notably, this type of immune conversion is occasionally associated with the generation of. certain types of suppressor macrophage populations. Read More

    Kekkaku 2016 Feb;91(2):41-4
    Background: Patients receiving surgical treatment for Mycobacterium avium complex (MAC), lung disease should be followed up with careful attention paid to relapse/recurrence, but there is some debate regarding the findings based on which relapse/recurrence should be diagnosed.

    Purpose And Methods: We hypothesized that we might be able to use anti-GPL core IgA antibodies (MAC antibodies), which have been attracting attention as a factor that may support diagnosis of MAC lung disease, to diagnose postoperative relapse/recurrence. Therefore, we compared the levels of these antibodies before and at the time of relapse/recurrence, and also compared antibody titers before and after surgery. Read More
