Hormonal determinants and effect of ER22/23EK glucocorticoid receptor gene polymorphism on health status deterioration in the participants of the Mataro Ageing Study.

ABSTRACT: The purpose of this study is to assess the potential relationships of circulating IGF-I, adrenal and gonadal steroids, and polymorphism ER22/23EK of the glucocorticoid receptor (GC-R) gene with nutritional, functional and cognitive deterioration in a group of elderly people living independently. This is a population-based prospective study with 313 individuals (160 women and 153 men, 76.7 ± 7 years) who participated. A physical exam, evaluation of functional capacity (Barthel scale), cognitive function (mini-mental state examination-MMSE), geriatric depression scale (GDS), mininutritional assessment (MNA-SF) and cardiometabolic status were performed at basal time point and at 2 years of follow-up. Biological measurements included cortisol, dehydroepiandrosterone (DHEA), DHEA sulphate, testosterone, estradiol, IGF-I and polymorphism ER22/23EK of the GC-R gene. Estradiol was associated with MNA-SF decrease over time (p < 0.01, adjusted for age and gender, beta =?-0.17, p = 0.03). Weight loss was related to testosterone in men (8.6 vs 12.1 pg/ml in no losers; p = 0.03), and in women with GDS (13.0% with depression vs 3.3% with no depression; p = 0.05) and MMSE (22.2% with cognitive deterioration vs 4.8% with no cognitive deterioration; p = 0.049). Barthel decrease was associated with testosterone (p = 0.02, after adjusting for age and gender, beta?=?-0.520, p < 0.001), and SHBG (p < 0.01, adjusted for age and gender, beta = 0.18, p < 0.01). DHEA was associated with deterioration in the MMSE (p = 0.01, after adjusting for age, gender, GDS scale and academic status, beta =?-0.26, p = 0.01). Frailty development was related only in men with testosterone levels at the beginning of the study (p = 0.017). ER22/23EK was found in 3% of the subjects and carriers had a lower prevalence of hypertension. Adrenal and gonadal steroids are associated to impairment of the ageing health condition in elderly individuals living independently in Spain. ER22/23EK polymorphism of the GC-R gene has a low prevalence in our population.

Project description:BackgroundPatients with COPD need to cope with a disabling disease, which leads to health status impairment.AimTo investigate the long term change of health status in subjects with mild to moderate airflow obstruction and to compare this to subjects without airflow obstruction, with and without a smoking history. Second, to investigate the factors potentially associated to rapid health status decline in our total cohort.MethodsTwo hundred and one subjects were included. Generic [Short form 36 health survey (SF36) and EuroQol - 5 dimensions (EQ-5D)] and disease specific [Clinical COPD questionnaire (CCQ) and COPD Assessment Test (CAT)] health status questionnaires were regularly repeated over a six years period. Other functional outcomes comprised measures of lung function, physical fitness, physical activity and emotional state.ResultsOn average, health status decline did not differ between groups with the exception of the EQ-5D index, which deteriorated faster in subjects with airflow obstruction compared to the never smoking control group [- 0.018(0.008) versus 0.00006(0.003), p = 0.03]. Subjects presenting at least one exacerbation had faster rate of deterioration measured with CAT [0.91(0.21) versus - 0.26(0.25), p < 0.01]. Characteristics of the fast declining group were older age, worse lung function, physical fitness, physical activity and disease specific baseline health status. Subjects with airflow obstruction had a 2.5 (95% CI 1.36-4.71) higher risk of presenting fast overall health status decline. Fast overall decline was associated with the presence of acute exacerbation(s) (44% of the subjects with exacerbation(s) versus 17% of subjects without exacerbation, p = 0.03). Changes in fat free mass, functional exercise capacity and in symptoms of anxiety and depression correlated weakly to changes in health status measured with all questionnaires.ConclusionSubjects with mild airflow obstruction present a significant deterioration of health status, which is generally not much faster compared to smoking and never smoking controls. Subjects with fast decline in overall health status are older and more likely to have airflow obstruction, acute respiratory exacerbation(s), reduced physical fitness, physical activity and impaired COPD specific health status at baseline.Trial registrationNCT01314807 - retrospectively registered on March 2011.
