However, the clinical significance of the positivity of Aspergillus precipitating antibody (APAb), a serodiagnostic test for pulmonary aspergillosis (PA), at the time of MAC-LD diagnosis is unknown. The objective of this study was to investigate the effects of APAb test results on the clinical outcomes of patients with MAC-LD. METHODS We retrospectively analyzed patients who were newly diagnosed as having MAC-LD between 2007 and 2014 in our hospital and checked for APAb at the time of diagnosis. RESULTS We enrolled 131 patients in this study. Of these patients, 20 (15.3%) tested positive for APAb at the diagnosis of MAC-LD. The APAb-positive patients were more frequently male (70.0% vs. 37.8%, P = 0.013) and more frequently had pulmonary emphysema (60.0% vs. 13.5%, P less then 0.001) and interstitial pneumonia (15.0% vs. 1.8%, P = 0.025) compared with the APAb-negative patients. During a median follow-up period of 4.0 years, PA developed in 12 of the APAb-positive patients (60.0%, CPA 9 and allergic bronchopulmonary aspergillosis 3) and 12 APAb-negative patients (10.8%, CPA 12) (P less then 0.001). The APAb-positive patients had a significantly higher rate of mortality than did the APAb-negative patients (P = 0.004). A multivariate analysis indicated that older age, lower albumin, fibrocavitary or fibrocavitary and nodular/bronchiectatic radiographic features, and APAb positivity were negative prognostic factors. CONCLUSIONS APAb-positive patients with MAC-LD more frequently develop PA and may have an unfavorable prognosis. PURPOSE To investigate the effects of low dose endotoxin on transcriptional activity in intestinal epithelium, and its role in necrotizing enterocolitis (NEC). METHODS Lipopolysaccharides (LPS) were injected into the amniotic cavity of pr
