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

Lower gel E2 account were pertaining to Mac computer-LD even in decades- and 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 < 0.001)> Table 3 Demographic characteristics of age- and BMI-matched case controls

Average E2 level of Mac-LD people was below that non-NTM End up being patients

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),>

Discussion

The chance of pulmonary NTM issues has grown in the world, and more than cases is actually pertaining to Mac-LD. However, no active cures or precautionary modality was developed to own Mac-LD due to the fact their pathogenesis was unsure. As most people that have Mac computer-LD is postmenopausal women, we speculated one to low solution E2 membership represent a prospective risk basis to possess Mac-LD. Our cross-sectional research revealed a connection between low gel E2 levels and you may MAC-LD during the postmenopausal women old 65 decades and younger. Age- and you can Bmi-paired analyses including presented the same style. At the same time, reduced serum E2 accounts have been observed in Mac but not in non-NTM Be, in women around 75 many years-old, indicating that lower solution E2 are associated specifically so you’re able to Mac computer-LD.

Although we didn’t study causal relationships between reasonable solution membership and you can Mac computer-LD, you are able that E2 was defensive against Mac computer disease. Tsuyuguchi et al. reported that ovariectomized mice got a high Mac load regarding lungs step 3–six days immediately after problems than just sham-run rats and E2-treated ovariectomized mice . Calippe ainsi que al. learned that much time-title E2 management to ovariectomized rats increased interleukin-1 beta secretion and you may inducible nitric oxide synthase expression which improved the fresh destroying off intracellular mycobacteria because of the resident peritoneal macrophages shortly after lipopolysaccharide stimulation . Such accounts signify E2 takes on a safety part against Mac computer problems, in accordance with the conclusions. However, to exhibit the fresh new defensive character out of E2 against Mac computer disease, after that fresh studies are crucial. Including, the change for the phagocytic and you will bactericidal results which have or instead E2 into the people macrophages could be looked. Concurrently, examining the effects out of alterations in weight, lung lbs, and you can lung pathology having fun with a mac computer-contaminated aromatase-knockout mouse (and this usually do not make E2 in a choice of the new ovary otherwise peripherally) you will strengthen our conclusion.
