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 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 Table 3 Demographic characteristics of age- and BMI-matched case controls

Median E2 amount of Mac computer-LD patients is actually lower than regarding low-NTM End up being customers
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

The newest frequency from pulmonary NTM illness has grown around the globe, and most cases is connected with Mac-LD. Yet not, no active procedures or preventive modality was developed having Mac computer-LD just like the their pathogenesis was unclear. Because so many people with Mac computer-LD was postmenopausal female, i speculated one to lower serum E2 accounts show a potential risk factor for Mac computer-LD. Our mix-sectional research revealed a link between lower gel E2 profile and MAC-LD during the postmenopausal women old 65 years and more youthful. This- and you may Body mass index-coordinated analyses in addition to showed the same fashion. On top of that, reduced gel E2 levels was in fact noticed in Mac yet not into the non-NTM Become, in women whenever 75 many years-old, suggesting one reasonable serum E2 is actually related particularly so you can Mac computer-LD.
While we did not investigation causal matchmaking ranging from low gel levels and you may Mac-LD, you’ll be able to one to E2 are defensive facing Mac problems. Tsuyuguchi ainsi que al. stated that ovariectomized mice had increased Mac burden from the lungs step 3–six weeks once disease than simply sham-manage rats and E2-handled ovariectomized rats . Calippe ainsi que al. discovered that enough time-label E2 management to help you ovariectomized mice increased interleukin-step 1 beta secretion and you can inducible nitric oxide synthase expression which increased the newest destroying regarding intracellular mycobacteria of the citizen peritoneal macrophages just after lipopolysaccharide pleasure . These types of reports indicate that E2 performs a safety role against Mac computer problems, in line with all of our findings. However, to show the fresh new protective part of E2 up against Mac computer infection, further fresh studies are crucial. As an instance, the change inside the phagocytic and you may bactericidal abilities having or in the place of E2 into the human macrophages would-be looked. Likewise, examining the results of alterations in body weight, lung lbs, and you may lung cystic having fun with a mac-contaminated aromatase-knockout mouse (and that do not generate E2 in either brand new ovary otherwise peripherally) you are going to bolster our very own conclusion.
