  • Changes in serum immunomolecules during antibiotic therapy for Mycobacterium avium complex lung disease.

Serum immunomolecules from 42 patients with MAC lung disease were assayed comparatively using an array-based system according to (i) patients with MAC lung disease at the time of diagnosis versus healthy controls and (ii) alterations after 12 months of antibiotic therapy in the MAC lung disease group. In addition, cytokine analyses were performed to determine whether cytokine responses were associated specifically with the disease phenotype, treatment outcome and aetiological agent. Notably, the serum concentrations of type 1 cytokine-associated molecules, such as CD40L, interferon (IFN)-γ, interleukin (IL)-8 and IL-23, were decreased significantly in patients at the time of diagnosis, suggesting that these molecules may serve as indicators of host susceptibility to MAC disease. Although the overall serum level of T helper type 1 (Th1)-related molecules, such as CD40L and IFN-γ, was restored after treatment, Th17-related cytokines, such as IL-17 and IL-23, were down-regulated significantly at 12 months post-treatment compared to pretreatment. Furthermore, these cytokine patterns differed among patient subgroups. Decreased serum concentrations of IL-17 and/or IL-23 were associated with failure of sputum conversion, the fibrocavitary disease phenotype and M. intracellulare lung disease. Thus, the reciprocal balance between Th1 and Th17 immunity during antibiotic therapy for MAC lung disease is critical for dictating the treatment response. In conclusion, a low level of Th1-related immunomolecules may perpetuate MAC lung disease, and the serum concentrations of Th17-related cytokines can reflect the treatment outcome, disease phenotype and aetiological agent.

  • Mycobacterium avium Complex in Day Care Hot Water Systems, and Persistence of Live Cells and DNA in Hot Water Pipes.
  • Bukh AS1, Roslev P.Author information 1Section of Biology and Environmental Science, Department of Biotechnology, Chemistry and Environmental Engineering, Aalborg University, Sohngaardsholmsvej 57, 9000, Alborg, Denmark.AbstractThe Mycobacterium avium complex (MAC) is a group of opportunistic human pathogens that may thrive in engineered water systems. MAC has been shown to occur in drinking water supplies based on surface water, but less is known about the occurrence and persistence of live cells and DNA in public hot water systems based on groundwater. In this study, we examined the occurrence of MAC in hot water systems of public day care centers and determined the persistence of live and dead M. avium cells and naked DNA in model systems with the modern plumbing material cross-linked polyethylene (PEX). The occurrence of MAC and co-occurrence of Legionella spp. and Legionella pneumophila were determined using cultivation and qPCR. Co-occurrences of MAC and Legionella were detected in water and/or biofilms in all hot water systems at temperatures between 40 and 54 °C. Moderate correlations were observed between abundance of culturable MAC and that of MAC genome copies, and between MAC and total eubacterial genome copies. No quantitative relationship was observed between occurrence of Legionella and that of MAC. Persistence in hot water of live and dead M. avium cells and naked DNA was studied using PEX laboratory model systems at 44 °C. Naked DNA and DNA in dead M. avium cells persisted for weeks. Live M. avium increased tenfold in water and biofilms on PEX. The results suggest that water and biofilms in groundwater-based hot water systems can constitute reservoirs of MAC, and that amplifiable naked DNA is relatively short-lived, whereas PEX plumbing material supports persistence and proliferation of M. avium.
