ENDOCRINOLOGY IN PREGNANCY: Bone metabolic changes during pregnancy: a period of vulnerability to osteoporosis and fracture

2015

Changes in bone density and bone markers suggest that pregnancy is associated with deterioration of bone mass in the mother. The metabolism of calcium resets to allow for the needs imposed by the building of the fetal skeleton. The fetus contributes to the process through the output of regulators from the placenta. Understanding of the whole process is limited, but some changes are unambiguous. There is an increase in the circulating levels of vitamin D, but its functional impact is unclear. Fetal parathyroid hormone (PTH) and PTH-related peptide (PTHrp) play an indirect role through support of a calcium gradient that creates hypercalcemia in the fetus. Placental GH, which increases up to t…

Fracture incidence and characterization in patients on osteoporosis treatment: The ICARO study

2006

None of the available osteoporosis therapies have been shown to completely abolish the risk of fractures. In clinical practice, the outcome may be even poorer. In 880 patients prescribed with antiresorptives (alendronate, risedronate, and raloxifene) for >1 year, a fragility fracture was recorded in 8.9%/year of them. This incidence is considerably higher than that observed in randomized clinical trials, and it was significantly related to poor compliance and lack of supplementation with calcium and vitamin D. Introduction: Osteoporotic fracture is one of the most important public health concerns among the elderly. Currently available therapies have been shown to significantly decrease the …

FokI Polymorphism of the Vitamin D Receptor Gene Correlates with Parameters of Bone Mass and Turnover in a Female Population of the Italian Island of…

2005

One of the most promising genetic approaches to dissecting a multifactorial disease is represented by genetically isolated population studies. We studied a genetic marker in a cohort of women living on the Mediterranean island of Lampedusa, a geographically isolated population. Lampedusa, located between the African coast and Sicily, consists of a young genetic isolate (<20 generations) with an exponential growth in the last generations. We analyzed the association between the FokI vitamin D receptor (VDR) gene polymorphism, previously proposed as a predictor of bone mass, with parameters of bone mass and turnover in a cohort of pre- and postmenopausal women living on Lampedusa. In 424 wome…

Role of comprehensive geriatric assessment in the management of osteoporotic hip fracture in the elderly: an overview

2013

Purpose: To highlight the advantages of comprehensive geriatric assessment (CGA) over usual care in the management of elderly patients with fragility hip fractures in terms of reducing the related mortality and disability. Method: An overview of publications on the topic was conducted using the MEDLINE and EMBASE databases. Results: Several models of geriatric and orthopedic comanagement have been developed in recent years, all characterized by a variable degree of integration, and they have been shown to reduce complications, disability and mortality in elderly hip-fracture patients. Preoperatively, CGA should identify the comorbidities that need to be treated in view of surgery, so as to …

FRI0299 Prevalence of Vertebral Fractures in Osteoporotic HIP Fractured Patients: The Focus Study

2015

Background Osteoporosis is a multifactorial systemic skeletal disease, characterized by low bone mass and microarchitectural modifications of bone tissue, with a consequent increase in fragility fractures [1]. Vertebral fractures are the most prevalent osteoporotic fractures and osteoporotic hip fractures are the most serious complication of osteoporosis resulting in increased mortality and high socio-economic cost [2,3]. The coexistence of these two pathological conditions in elderly patients has been previously described, leading to even worse functional outcomes than each one alone [4]. Objectives To determine the prevalence of vertebral fractures in osteoporotic hip fractured women and …

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…
