Estrogen Sensitivity

Although it is well established that estrogen deficiencycauses osteoporosis among the postmenopausalwomen, the involvement of estrogen receptor (ER) in itspathogenesis still remains uncertain. In the presentstudy, we have generated rats harboring a dominantnegative ERa, which inhibits the actions of not only ERabut also recently identified ERb. Contrary to our expectation,the bone mineral density (BMD) of the resultingtransgenic female rats was maintained at the same levelwith that of the wild-type littermates when sham-operated.In addition, ovariectomy-induced bone loss wasobserved almost equally in both groups. Strikingly, however,the BMD of the transgenic female rats, after ovariectomized,remained decreased even if 17b-estradiol(E2) was administrated, whereas, in contrast, the decreaseof littermate BMD was completely prevented byE2. Moreover, bone histomorphometrical analysis ofovariectomized transgenic rats revealed that the higherrates of bone turnover still remained after treatmentwith E2. These results demonstrate that the preventionfrom the ovariectomy-induced bone loss by estrogen ismediated by ER pathways and that the maintenanceof BMD before ovariectomy might be compensatedby other mechanisms distinct from ERa and ERbpathways.

The only available treatment for celiac disease is life-long gluten exclusion. We conducted a cross-sectional age- and gender-matched study in 64 celiac adults on a long-term (>1 year) gluten-free diet and 74 non-celiac volunteers from Spain, using dietary, anthropometric, and biochemical parameters, as well as assessing bone mineral density and physical activity. Celiac adults had deficient intake (below 2/3 of the recommended intake) for folates, vitamin E, and iodine and low intake of calcium (below 80% of the recommended intake). Iron intake was also below 2/3 of the recommended intake in celiac women. Vitamin D intake was extremely low, and 34% of celiac patients had moderately deficient plasma levels. According to bone mineral density, celiac women may be more prone to osteopenia and osteoporosis. However, we found a perfectly analogous nutritional status scenario in celiac as compared to healthy volunteers, with the dietary deviations found being similar to those of the Spanish population, i.e., both groups followed a high-lipid, high-protein, and low-carbohydrate diet. Values for biochemical parameters were found within the reference ranges. Celiac disease had no influence on body weight, but body fat in celiac patients tended to be higher. According to our results, vitamin D, calcium, folates, vitamin E, iodine, and iron nutritional status should be specifically assessed and monitored in the celiac population.
