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 profile was associated with Mac-LD inside age- and you can Body mass index-paired 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 customers was below compared to non-NTM Become 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),>

Dialogue

Brand new chance off pulmonary NTM problems has increased international, and more than times try linked to Mac-LD. not, no effective therapy or precautionary modality has been developed to own Mac-LD once the the pathogenesis is not sure. Because so many people that have Mac computer-LD are postmenopausal feminine, i speculated you to low serum E2 membership depict a potential exposure grounds having Mac computer-LD. The get across-sectional studies found a link between low solution E2 membership and you may MAC-LD inside the postmenopausal female old 65 years and you may younger. Age- and you will Body mass index-matched up analyses as well as presented a comparable trends. While doing so, reasonable solution E2 levels had been noticed in Mac computer although not for the non-NTM Feel, in women approximately 75 many years-dated, suggesting one to lower gel E2 was relevant specifically so you can Mac-LD.

Although we don’t analysis causal dating between low solution membership and Mac computer-LD, it will be easy you to definitely E2 was protective up against Mac computer infection. Tsuyuguchi ainsi que al. stated that ovariectomized rats had a top Mac weight in the lungs step 3–six days shortly after issues than sham-operate rats and E2-treated ovariectomized mice . Calippe mais aussi al. discovered that much time-title E2 administration to help you ovariectomized rats enhanced interleukin-1 beta hormonal and you may inducible nitric oxide synthase phrase which enhanced the newest killing of intracellular mycobacteria because of the citizen peritoneal macrophages once lipopolysaccharide pleasure . This type of reports indicate that E2 plays a safety role against Mac computer problems, relative to our findings. Although not, to exhibit the fresh protective part out-of E2 up against Mac problems, subsequent fresh scientific studies are extremely important. As an example, the alteration for the phagocytic and you may bactericidal show that have otherwise instead E2 in individual macrophages might be searched. On top of that, assessing the effects from changes in lbs, lung lbs, and you may lung pathology using a mac-contaminated aromatase-knockout mouse (which you should never generate E2 in either the latest ovary or peripherally) you are going to strengthen the achievement.
