HLA antigens and immunoresponsiveness to insulin in insulin-dependent diabetes mellitus.

2008

HLA-A and B antigens were determined in 112 patient with insulin-dependent juvenile onset diabetes mellitus, who could be subdivided into “non” and “high responders” to insulin. The data revealed a trend of an association of these diabetes subgroups with only one of the diabetes-associated antigens HLA-B8 and HLA-BW15 and indicated the existence of at least two different genetic constellations for susceptibility to juvenile diabetes mellitus. One form with a strong immune-response to insulin seemed to be associated with HLA-BW 15 and the other form without humoral immunoreactivity to insulin seemed to be associated with the presence of HLA-B8 and the absence of HLA-B7.

Improvement of quality of life during treatment with anabolic therapy: Results of a multicenter study

2012

Efficacy and safety of daily treatment with parathyroid hormone were evaluated in a typical Italian population with severe post-menopausal osteoporosis eligible to anabolic treatment (Nota 79 AIFA). Materials and methods: 204 ambulatory female patients (median age: 72.6±8.3 years; height: 155.3±6.5 cm; weight: 61.1±11.9 Kg) with severe post-menopausal osteoporosis have been enrolled in this study accordingly to summary of product characteristics and Italian reimbursement criteria for osteoporosis drugs (Nota 79 AIFA), between January 2008 and April 2009 (Last Patient Out: October 2010). 146 (71.57%) out of these patients completed the study.6 visits were planned in the study protocol: basel…

The Val432Leu polymorphism of the CYP1B1 gene is associated with differences in estrogen metabolism and bone density.

2009

Polymorphisms of the CYP450 genes that encode for the enzymes that metabolize estrogen are linked to hormone-related cancers. We investigated the impact of two polymorphisms of the CYP1B1 gene previously reported to be associated with hormone-related disorders on estrogen metabolism and bone mineral density (BMD), another hormone-dependent condition, in women from different ethnic backgrounds. Four hundred sixty-eight postmenopausal Caucasian women, 220 from St. Louis, MO, USA (mean age=63.5+/-0.53 years) and 248 from Palermo, Italy (mean age=72.9+/-0.44 years) participated in the study. Measurements of urinary estrogen metabolites by enzyme-linked immunoassay, serum estradiol by ultrasensi…

Effects of polymorphisms of the sex hormone-binding globulin (SHBG) gene on free estradiol and bone mineral density.

2009

Polymorphisms of the sex hormone-binding globulin (SHBG) gene are associated with differences in SHBG levels, influencing the risk for breast cancer and polycystic ovarian syndrome, but no association has been reported for osteoporosis in postmenopausal women.To determine the effect of G to A substitution in the 5'UTR (rs1799941) and the Asp356Asn (rs6259) polymorphisms of the SHBG gene on bone mineral density (BMD).This is a cross-sectional study in a university-based research center from May, 2002 to December, 2007. A total of two hundred and thirteen healthy postmenopausal Caucasian womenor = 1 year from last menstrual period participated to this study. Serum estradiol by ultrasensitive …

Change in bone mass distribution induced by hormone replacement therapy and high-impact physical exercise in post-menopausal women.

2002

The purpose of this intervention trial was to determine whether changes in bone mass distribution could be observed in postmenopausal women following hormone replacement therapy (HRT) and/or high-impact physical exercise. Eighty healthy women, aged 50-57 years, at5 years after the onset of menopause and with no previous use of HRT, were randomly assigned to one of four groups: HRT; exercise (Ex); HRT + Ex (ExHRT); and control (Co). HRT administration was conducted in a double-blind manner for 1 year using estradiol plus noretisterone acetate (Kliogest). The exercise groups participated in a 1 year progressive training program consisting of jumping and bounding activities. Subjects participa…

Effect of alendronate and exercise on bone and physical performance of postmenopausal women: a randomized controlled trial.

2003

In this randomized, double-blind, placebo-controlled 12-month trial we evaluated effects of weight- bearing jumping exercise and oral alendronate, alone or in combination, on the mass and structure of bone, risk factors for falling (muscle strength and power, postural sway, and dynamic balance), and cardiorespiratory fitness in postmenopausal women. A total of 164 healthy, sedentary, early postmenopausal women were randomly assigned to one of four experimental groups: (1) 5 mg of alendronate daily plus progressive jumping exercise, (2) 5 mg alendronate, (3) placebo plus progressive jumping exercise, or (4) placebo. The primary endpoint was 12-month change in bone mass and geometry (measured…

The population-based prevalence of osteoporotic vertebral fracture and densitometric osteoporosis in postmenopausal women over 50 in Valencia, Spain …

2010

Purpose: To estimate the prevalence of vertebral fracture and densitometric osteoporosis in postmenopausal women over the age of 50 in Valencia, Spain. Methods: This cross-sectional study was conducted in 2006-2007. An age-stratified population-based random sample of 824 postmenopausal women over the age of 50 answered a questionnaire and received a densitometric examination of the lumbar spine and hip with dual-energy X-ray absorptiometry and a lateral X-ray of the thoracic spine and lumbar regions. Osteoporosis was defined as a T-score less than or equal to -2.5 compared to a population of young women, and the presence of vertebral fractures was classified according to Genant's semiquanti…
