Osteoporosis in patients on long-term home parenteral nutrition: a longitudinal study.

The prevalence of osteoporosis was investigated in 88 patients with intestinal failure (IF). Osteoporosis was found in 67%, dependent of body mass index and age when IF occurred. In 56 patients on HPN, followed prospectively, changes in bone density were dependent on the duration of HPN; older patients had a higher increase. INTRODUCTION: It has been suggested that low bone mass and negative bone balance may occur in adult patients receiving home parenteral nutrition (HPN). The aim of this study was to assess prospectively the prevalence of osteoporosis in intestinal failure (IF) patients and the changes in bone mineral density in those on long-term HPN and to analyze the factors that may influence the occurrence and evolution of osteoporosis. MATERIALS AND METHODS: Bone mineral density was measured at the lumbar spine and femoral neck in 88 IF patients. RESULTS: At the first bone mineral density determination (baseline), the prevalence of osteoporosis was 67% in this population (median age, 52 years). Ten percent of the patients with osteoporosis experienced fragility fractures. Osteoporosis was independent of age and gender but occurred earlier in patients who had received corticosteroids. At baseline, the lumbar Z-score was positively correlated mainly to body mass index and age when IF occurred; these two parameters explained 34% of the Z-score. Repeated measurements were performed in 56 patients during long-term HPN (mean duration, 5.5 +/- 1.2 years). The changes in Z-score at the lumbar spine were dependent on the age when IF occurred and on the duration of HPN, with a synergistic effect between them. The older the patients, the higher the increase in Z-score during HPN. CONCLUSION: HPN had no deleterious effect on cortical bone and actually improved trabecular bone in patients whose intestinal disease started after the age of 21 years.     

Prevalence and determinants of osteoporosis among men aged 50 years or more in Sri Lanka: a community-based cross-sectional study

Summary

This study, based on phalangeal bone mineral density (BMD) of 1,174 community dwelling male volunteers aged 50 years or more from seven provinces in Sri Lanka, shows 5.8% prevalence of osteoporosis among them. Advancing age, less physical activity, and low body weight were associated with low BMD. Men with larger families were more likely to have a lower bone mineral density.

Purpose

The prevalence of osteoporosis among Sri Lankans is not well-known. We wished to estimate the prevalence and determinants of osteoporosis among older men in Sri Lanka.

Methods

One thousand one hundred seventy-four healthy, community dwelling male volunteers, aged 50 years or more from seven out of nine provinces in Sri Lanka underwent phalangeal bone mineral density estimation using an AccuDXA® scanner. We calculated T scores using the local reference data, and subjects with T score equal or less than ?2.5 was considered to have osteoporosis.

Results

Sixty-six men (5.8%) were detected to have osteoporosis. In contrast to men in the highest tertile of bone mineral density, men in the lowest tertile were older (60.0 versus 55.8 years, p?<?0.001), lighter (56.3 versus 65.6 kg, p?<?0.001), less physically active (16.1% versus 5.5%, p?<?0.001) and had larger families consisting of four or more children (36% versus 20.9%, p?<?0.001). Smoking, alcohol, or milk consumption showed no association with bone mineral density.

Conclusions

We report 5.8% prevalence of osteoporosis among men older than 50 years in Sri Lanka, and advancing age, less physical activity, and low body weight were associated with low bone mineral density. Men with larger families were more likely to have a lower bone mineral density.     

Influence of environmental cadmium exposure on forearm bone density.

Cadmium may have both direct and indirect effects on bone turnover. It is nephrotoxic and can interfere with vitamin D metabolism. Such perturbation may result in osteoporosis and osteomalacia. In this study, a total of 790 persons (302 males and 488 females) participated; they were all over 35 years old and resided in an area near a cadmium smelter in southeast China. All participants completed a questionnaire, and bone mineral density was measured by SPA-4 single-photon absorptiometry at the radius and ulna. Cadmium content of urine was determined by graphite-furnace atomic absorption spectrophotometry as a measure of dose. The decline in bone mineral density with age in a heavily polluted area was greater than that in a control area for subjects over 60 years of age of both sexes (p < 0.05). In single regression, forearm bone densities were negatively correlated with urinary cadmium excretion in both males and females (p < 0.001), whereas stepwise regression showed that forearm bone density decreased linearly with age (p < 0.001) and urinary cadmium (p < 0.01) in both sexes, suggesting a dose-effect relationship between cadmium dose and bone mineral density. Based on the World Health Organization criteria, (bone mineral density < -2.5 SDs below the normal young adult), the prevalence of osteoporosis in women increased from 34.0% in the control area to 51.9% in the heavily polluted area (p < 0.01) among subjects over 50 years old, and the odds ratio value was 2.09 (95% CI: 1.08-4.03) for the highly polluted area compared with the control area. A striking observation in the study was the marked increase of the prevalence of fracture in the cadmium-polluted area in both sexes. It was concluded that environmental exposure to cadmium is associated with an increased loss of bone mineral density in both males and females, leading to osteoporosis and increased risk of fractures, especially in the elderly and in females.

Two clinical problems in elderly men: osteoporosis and erectile dysfunction

Seventy-six of 108 random men aged 50 years or over were evaluated for erectile dysfunction with interviews of patients using the International Index of Erectile Function Form and minimal evaluation. Serum hormone concentrations were measured. Bone mineral density was measured using dual energy x-ray absorptiometry. Hormone levels did not show significance in terms of erectile dysfunction or bone mineral density results. Erectile dysfunction was determined in 57 (75%) of 76 patients. Ten (13.2%) patients had osteoporosis and 45 (59.2%) had osteopenia at the bone mineral density measurements. The distribution of bone mineral density groups relating to erectile dysfunction did not show significance. The frequencies of osteoporosis and erectile dysfunction increased with age, but the association of these conditions seems to be independent of each other and hormonal changes appear not to be the major determinants for both conditions in elderly men.     

Clinical utility of spine bone density in elderly women.

It is common clinical practice to obtain a bone density measurement at both the hip and spine to evaluate osteoporosis. With aging, degenerative changes in the lumbar spine may elevate the bone mineral density (BMD) results giving false assurances that the fracture risk at the spine is low. We examined the association of spine osteoarthritis and bone mineral density in 1082 community-dwelling ambulatory older women aged 50-96 years who participated in a 1992-1996 osteoporosis research clinic visit. The BMD was measured at the hip and posteroanterior (PA) and lateral lumbar spine using dual energy X-ray absorptiometry (DXA). Spine osteoarthritis was identified on the PA lumbar spine DXA images by a musculoskeletal radiologist. Forty percent of women had evidence of spine osteoarthritis (OA). Women with spine OA had a mean age of 77.4 yr (95% confidence interval [CI]: 76.5-78.2), were significantly older than women without spine OA (mean age, 66.8 yr; 95% CI: 65.9-67.7), and were more likely to have prevalent radiographic fractures (14.2% vs. 9.5%; p<0.05). Age-adjusted BMD at the femoral neck, total hip, PA spine, and lateral spine was significantly higher in women with spine OA. Women with spine OA were more likely to have osteoporosis by the World Health Organization classification at the femoral neck and total hip than those without spine OA, but less likely based on the PA spine (14.4% vs. 24.5%). Despite higher BMD levels, women with OA of the lumbar spine had higher prevalence of osteoporosis at the hip and more radiographic vertebral fractures. In elderly women 65 yr and older who are likely to have spine OA, the DXA measurement of the spine may not be useful in assessing fracture risk, and DXA of the hip is recommended for identification of osteoporosis.
