Asthma associated with low selenium, low zinc, high copper, low glutathione peroxidase, glutathione reductase, and catalase activity; in contrast, increased hs-CRP, and TBARS was noted. Interesting that FEV1 and FVC positively correlated with Se levels.
Higher Testosterone and DHT levels in men was found to be positively associated with FEV1 and FVC; Estradiol was not. The question here is cause or effect.
Also interesting is the fact that smokers had higher Testosterone levels compared to non-smokers.
