According to the logistic regression analysis, age and low serum E2 levels were independently related to MAC-LD (Table 2). As expected, the number of years after menopause was strongly correlated with age (Spearman’s rank correlation coefficient; r = 0.727, p < 0.001);> Table 2 Multivariate analysis of the relationships between MAC-LD and age, BMI, and sex hormones

Among 42 patients with MAC-LD and 91 healthy controls, 17 patients with MAC-LD and 17 healthy controls were matched (Table 3). Even after age and BMI were matched, serum E2 (2.05 pg/mL vs. 13.0 pg/mL, p < 0.001)> Table 3 Demographic characteristics of age- and BMI-matched case controls

Median E2 number of Mac computer-LD customers is below that of low-NTM Be people
We used 88 pooled samples of MAC-LD patients obtained from ples of non-NTM BE patients obtained from ples from 20 patients with MAC-LD and samples from 11 non-NTM BE patients were compared. Consistent with matching, we found that the median age (74 years vs 76 years, p = 0.699) and BMI ( kg/m 2 vs kg/m 2 , p = 0.984) of MAC-LD patients were equivalent to those of non-NTM BE patients. Median serum E2 levels in MAC-LD patients were significantly lower than median plasma E2 levels in non-NTM BE patients (1.79 pg/mL vs. 11.0 pg/mL, p < 0.001),>

New chance out-of pulmonary NTM problems has increased international, and most times try related to Mac computer-LD. not, no active cures or preventive modality was developed to own Mac computer-LD once the its pathogenesis are not sure. As most clients having Mac-LD try postmenopausal feminine, we speculated that reduced serum E2 membership show a possible exposure basis to own Mac-LD. The cross-sectional research revealed a connection between lower solution E2 account and you may MAC-LD within the postmenopausal female aged 65 age and young. This- and Body mass index-coordinated analyses in addition to demonstrated a comparable trends. In addition, reasonable gel E2 levels have been found in Mac computer but not during the non-NTM Be, in women everything 75 many years-old, recommending you to lower gel E2 was relevant particularly to Mac-LD.
Although we don’t research causal dating ranging from reasonable serum account and you may Mac-LD, you will be able one E2 are protective facing Mac infection. Tsuyuguchi et al. reported that ovariectomized rats had a top Mac load from the lungs 3–6 weeks shortly after problems than simply sham-run mice and you will E2-treated ovariectomized mice . Calippe ainsi que al. unearthed that much time-name E2 government to help you ovariectomized mice improved interleukin-1 beta secretion and you may inducible nitric oxide synthase term hence enhanced the eliminating of intracellular mycobacteria by the citizen peritoneal macrophages shortly after lipopolysaccharide pleasure . This type of records mean that E2 takes on a safety part facing Mac computer disease, prior to the results. not, to display the newest protective part away from E2 up against Mac computer infection, subsequent fresh research is important. For example, the change in the phagocytic and you can bactericidal abilities that have or as opposed to E2 during the human macrophages could be searched. At the same time, determining the results off alterations in body weight, lung pounds, and you will lung cystic using a mac-contaminated aromatase-knockout mouse (and this try not to write E2 either in brand new ovary otherwise peripherally) you will strengthen our very own conclusion.
