Serum degrees of sex hormone

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

Lower solution E2 levels was related to Mac-LD inside age- and you can Bmi-matched subgroups
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 people was below that non-NTM Be 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
Discussion
The new frequency from pulmonary NTM infection has grown global, and more than instances was pertaining to Mac-LD. not, no energetic treatment otherwise precautionary modality has been developed having Mac computer-LD because the the pathogenesis was unclear. Because so many customers with Mac-LD try postmenopausal women, i speculated one to lowest serum E2 profile represent a possible risk foundation getting Mac-LD. The cross-sectional research shown a match up between lowest gel E2 levels and you will MAC-LD inside the postmenopausal female aged 65 age and you can younger. This- and you may Body mass index-matched up analyses together with shown the same trends. In addition, reduced gel E2 account was indeed noticed in Mac although not from inside the non-NTM Feel, in females everything 75 ages-old, recommending you to lowest serum E2 is related particularly so you can Mac-LD.
Although we didn’t research causal relationship ranging from lower serum accounts and you can Mac computer-LD, it is possible one to E2 is actually protective facing Mac infection. Tsuyuguchi et al. stated that ovariectomized mice had a higher Mac burden in the lung area 3–6 days after illness than just sham-work rats and you may E2-managed ovariectomized rats . Calippe et al. discovered that a lot of time-term E2 management to help you ovariectomized rats increased interleukin-step 1 beta hormonal and you can inducible nitric oxide synthase phrase and this enhanced the new destroying off intracellular mycobacteria by citizen peritoneal macrophages once lipopolysaccharide arousal . Such profile signify E2 performs a defensive role against Mac computer infection, according to the results. Yet not, to demonstrate the defensive role out-of E2 against Mac computer infection, next fresh studies are very important. As an example, the change inside the phagocytic and you may bactericidal abilities having or as opposed to E2 inside the human macrophages is looked. Additionally, assessing the results out of changes in weight, lung weight, and you may lung pathology using a mac-infected aromatase-knockout mouse (and therefore dont write E2 in a choice of brand new ovary or peripherally) you’ll reinforce our very own conclusion.
