Osteoporos Int 200l; 12:519-528 The FRACTURE Index is useful in the assessment of 5-year risk of hip and other osteoporotic fractures in older postmenopausal women, with or without bone mineral density (BMD) testing. It also helps clinicians identify and determine further evaluation/ treatment needs for high-risk patients and is predictive of hip, vertebral, and nonvertebral fractures. The Study of Osteoporotic Fractures (SOF SOF abbr. sound on film ) in 7,782 women [greater than or equal to]65 years of age provided data for the development of the Fracture Index, which includes these variables: age, BMD T-score, fracture after 50 years of age, maternal hip fracture after age 50 years, weight [less than or equal to] 125 pounds (57 kg), smoking status, and use of arms to stand up from a chair. Ambulatory women [greater than or equal to] 65 years of age were recruited from population-based listings in Oregon, Minnesota, Maryland, and Pennsylvania; the analysis excluded Caucasians who had a previous hip fracture or bilateral hip replacement. Mean age was 73.3 years, wi th a total hip BMD T-score of-1.5. A strong relationship exists between the FRACTURE Index and hip fracture risk, and it is shown even stronger when BMD measurement is included. Age is the most important component of the index, and higher values occur more often in older women. Further clinical evaluation clinical evaluation Medtalk An evaluation of whether a Pt has symptoms of a disease, is responding to treatment, or is having adverse reactions to therapy is recommended for postmenopausal women with a total score of [greater than or equal to] 6 with BMD assessment or [greater than or equal to] 4 without BMD assessment. * Dargent-Molina P, Poitiers F, Breart G: In elderly women, weight is the best predictor of a very low bone mineral density: evidence from the EPIDOS EPIDOS European Patent Information and Documentation Systems study.

Conjugate. estrogens, conjugated Warning - Hazardous drug! C.E.S. equine estrogen (CEE cee n. The letter c. ). The study consisted of three treatment arms: placebo, 10 mg/day alendronate alone, or 10 mg/day alendronate combined with CEE 0.625 mg/day. All subjects received 500 mg/day calcium. Participants were randomized and a subset of subjects were selected to receive bone biopsy Bone Biopsy Definition Bone biopsy is the removal of a piece of bone for laboratory examination and analysis. Purpose Bone biopsy is used to distinguish between malignant tumors and benign bone disease such as osteoporosis and with histomorphometry at the end of the study. Results indicate that the placebo group displayed a mean 0.6% loss in lumbar spine BMD. The patients treated with alendronate, CEE, and alendronate with CEE showed an increase in BMD of 6.0% (P<.001 vs. placebo), 6.0% (P<.001 vs. placebo), and 8.3% (P<.001 vs. placebo and CEE; P=.022 vs. alendronate), respectively. Bone marker tur nover for the biochemicals urinary N-telopeptide of type I collagen and serum alkaline phosphatase significantly decreased in the presence of alendronate and CEE. Slightly greater decreases in bone marker levels were observed in the combined agent group (alendronate + CEE) when compared to either agent alone. Normal bone histology histology (hĭstŏl`əjē), study of the groups of specialized cells called tissues that are found in most multicellular plants and animals. was shown in the subset of participants undergoing bone biopsies with a significant decrease in biochemical markers and a moderately greater decrease in the combined agent group. * Chrischilles EA, Dasbach EJ, Rubenstein LM, et al: The effect of alendronate on fracture-related healthcare utilization and costs: the fracture intervention trial. Osteoporos Int 2001; 12:654-660 Spine, forearm and hip fractures are reduced as a result of alendronate therapy. A study involving 2,027 women aged 55 to 81 with low bone mass was conducted to determine fracture-related healthcare utilization and cost between alendronate treated patients and placebo patients. Alendronate was administered to a randomized group of patients (5 mg/day for 2 years). The control group received a placebo for 3 years. The number of patients incurring fractures and the costs thereof decreased significantly in the treated group compared to the placebo group. Fracture-related healthcare cost including treatment at emergency room, hospital, rehabilitation, or nursing home fell for the alendronate group by 25 %(P= .038). Hip-fracture related healthcare costs fell 58%, or $181 per patient (P = .036) randomized. Total fracture-related costs were 35% or $190 per patient randomized when compared to the placebo group. Associated morbidity and proportion of patients utilizing healthcare resources are reduced through the use o f alendronate therapy.

Study subjects who were postmenopausal at least 5 years (n=299) were randomized to receive 10 mg/day alendronate, 200 IU/day intranasal calcitonin, or a placebo for 12 months. BMD measurements were assessed by dual-energy x-ray absorptiometry and biochemical markers of bone turnover were assayed. Results show that bone mass in the alendronate group relative to the calcitonin group increased by 5.16% vs 1.18% (P < .00 1) in the lumbar spine, 4.73% vs 0.47% (P < .001) in the trochanter trochanter /tro·chan·ter/ (tro-kan´ter) a broad, flat process on the femur, at the upper end of its lateral surface (greater t.), or a short conical process on the posterior border of the base of its neck (lesser t.) . , and 2.78% vs 0.58% (P<.001) in the femoral neck, respectively. A greater decrease in serum alkaline phosphatase and urinary N-telopeptide occurred in the alendronate group compared to the calcitonin and placebo groups. BMD slightly increased in the femoral neck of the calcitonin group relative to the placebo group, but not in the trochanter or l umbar spine. Negative effects are reported with equal frequency in all groups indicating that both alendronate and calcitonin are well tolerated among postmenopausal women. This multicenter, randomized study indicates that alendronate is effective in the treatment of osteoporosis in postmenopausal women and both calcitonin and alendronate are well tolerated. * Lanza FL, Hunt RH, Alan B, et al: Endoscopic en·do·scope n.

In a study designed to compare the upper gastrointestinal (GI) safety and tolerability of risedronate and alendronate, researchers randomized men and postmenopausal women (aged 45 to 80 years) into one of three treatment groups: placebo with aspirin 650 mg qid for the last 7 days (n = 20), alendronate 40 mg/day (n = 90), or risedronate 30 mg/day (n= 89). Following 28 days of treatment it was found through the use of endoscopy that risedronate and alendronate groups had similar mean gastric and duodenal scores. Both treated groups displayed markedly lower gastroduodenal irritation compared with the placebo/aspirin group (3% vs 60%), respectively. This multicenter, double-blind, active- and placebo-controlled study indicates that risedronate and alendronate have GI tolerability and safety profiles similar to those of a placebo. * Lowe CE, Depew WT, Vanner SJ, et al: Upper gastrointestinal toxicity of alendronate.

A trial designed to test the efficacy of alendronate was conducted on osteoporotic men (n = 241; mean age, 63 years). Study data indicate men who receive 10 mg/day alendronate have a mean increase in BMD at the lumbar spine (7.1 [+ or -] 0.3), at the femoral neck (2.5% [+ or -] 0.4%), and total body (2.0% [+ or -] 0.2%) compared to baseline (P<.001, for all). Men who receive placebo experience an increase in BMD at the lumbar spine (1.8% [+ or -] 0.5%); yet no significant increase is apparent in the femoral neck or total body (P< .001 in relation to baseline BMD). BMD gains are greater, and vertebral fractures are decreased in the alendronate-treated group. Men in the alendronate group have a decrease in height of 0.6 mm compared to a 2.4 mm decrease in the placebo group.

Participants were randomized into three treatment groups: placebo, 5 mg/day alendronate, or 10 mg/day alendronate. Study data indicate that continued treatment with 10 mg/day of alendronate for 7 years results in lumbar spine BMD increases of 11.4% compared to baseline. An increase of 0.8% in BMD for the 10 mg/day group and a 0.6% gain for the 5 mg/day group is observed each additional year through the seventh year, and after the initial 18 months. Substantial increases in BMD were also observed in the period between the sixth and seventh years. Of the women previously receiving alendronate over the past five years, then were switched to a placebo, no significant decrease in BMD was observed at the hip or spine; however, decreases in BMD at the total body and forearm along with small elevations in bone marker turnover were noted.

Other related parameters such as age, gender, and onset of GH deficiency were equal between groups. No changes occurred in the control group, while BMD increased and all measured parameters of bone turnover decreased in the rhGH/ alendronate group. No fractures were reported in either group.

Kyphoplasty is a new technique for treating vertebral compression fractures and involves the placement of inflatable bone tamps into the vertebral body. Inflation of the bone tamps increases height of the vertebral body and creates a cavity to be filled with bone cement.

SI was notably correlated with serum NTx levels (r = -0.26; P < .001) and age (r = -0.41; P < .001). There was no correlation with serum concentrations of bone-specific alkaline phosphatase. SI was also significantly correlated with years since menopause (r = 0.40; P < .001). A significant decrease in SI levels occurred at least a decade before an increase in serum NTx concentrations developed. Based on US reference data, 9% of the participants had T-scores indicative of osteoporonis, and 24% had T-scores indicative of osteopenia. * Yao WJ, Wu CH, Wang ST, et al: Differential changes in regional bone mineral density in healthy Chinese: age-related and sexdependent. Calcif Tissue mt 2001; 68:330-336 Bone mineral density (BMD) reduction is both age- and sex-related, and bone loss is three times greater in Chinese women than that of men. A study to investigate the relationship of age-related and sex-dependent BMD variations in six skeletal sectors was conducted on 697 healthy Chinese men and women (310 women, 387 men) aged 20 to 80 years. Researchers utilized dual-energy x-ray absorptiometry (DXA) to measure total-body and regional BMD. Results indicate a five-phase change in the axial bones of women. No obvious peak was observed in appendicular appendicular /ap·pen·dic·u·lar/ (ap?en-dik´u-lar) 1. pertaining to the vermiform appendix. 2. pertaining to an appendage. ap·pen·dic·u·lar adj. 1. bones. At 50 to 54 years of age a significant bone decrease was noted in women. The overall total body bone decrease was 19.3%, 20.4% for the legs, 23.9% for the anns, 29% for the spine, 23% for the pelvis, 18.2% for the ribs and 16.4% for the head. Men displayed a maximal bone mass at 35 to 39 and 30 to 34 years old for appendicular and axial bones, respectively. An insignificant age-related bone loss in all skeletal sectors was noted, except from ages 60 to 64 an d 65 to 69 years. In each region the overall bone decrease from maximal bone mass to 70 to 80 years old was 6.7% for total body, 10.4% for legs, 7.8% for arms, 7.6% for spine, 11.3% for the pelvis, 9.5% for the ribs, and 1.7% for the head. This study data indicate that regional and age/sex dependent variations of BMD occur within the Chinese population. * Mackelvie KJ, McKay HA, Khan KM, et al: Lifestyle risk factors for osteoporosis in Asian and Caucasian girls.

MEN * Adler RA, Funkhouser HL, I-Jolt CM: Utility of heel ultrasound bone density in men. J Clin Densitom 2001; 4:225-230 * Although there is a stro.ng correlation between the spine and hip bone mineral density (BMD) by dual x-ray absorptiometry (DXA) and the heel quantitative ultrasound index, no heel T-score can be used with good sensitivity and specificity to predict osteopenia or osteoporosis in men. This study to ascertain whether a heel ultrasound measurement could accurately predict central BMD was conducted on 185 men (136 Caucasian, 1 Asian, and 48 African-American), mean age, 63 years. Researchers utilized DXA to determine BMD of the spine and hip of participants using heel US T-score predictive values for osteopenia and osteoporosis. * Orwoll ES, Bevan L, Phipps KR: Determinants of bone mineral density in older men.
