Objective: In children with Prader-Willi syndrome (PWS), growth hormone (GH) treatment has positive effects on bone mineral density (BMD). Two one-year studies did not show a difference between GH or placebo on BMD in young adults with PWS. However, there are no studies investigating BMD during longer-term GH treatment in young adults with PWS. Design: Open-label, prospective study in 43 young adults with PWS. Methods: BMD of the total body (BMDTBSDS) and lumbar spine (BMADLSSDS) measured by DXA. Results: In the total group, estimated mean (95% CI) BMDTB remained similar during 3 years of GH, being -0.76 (-1.11 to -0.41) SDS at start and -0.90 (-1.27 to -0.54) SDS after 3 years (p=0.11), as did BMADLS, being -0.36 (-0.72 to 0.01) SDS and -0.46 (-0.77 to -0.16) SDS resp. (p=0.16). In men, there was a significant decrease in BMDTBSDS during 3 years of GH, while BMADLSSDS remained similar. In women, both BMDTBSDS and BMADLSSDS remained similar. BMDTBSDS was associated with female sex, lean body mass and age. The majority of patients received sex steroid replacement therapy (SSRT). Conclusions: During 3 years of combined GH and SSRT treatment, BMD remained stable in the normal range in young adults with PWS. However, men showed a decline in BMDTBSDS, probably due to insufficient SSRT. We recommend to continue GH treatment in young adults with PWS and to start SSRT during adolescence unless puberty progresses normally.

Bone turnover and bone mineral density in young adult partients with panhypopituitarism before and after long-term growth hormone therapy. Eur J Endocrinol 1995;132:42–6. ISSN 0804–4643 We examined the effects of biosynthetic growth hormone (GH) on biochemical indices of bone turnover and on bone mineral density in a group of GH-deficient adults. Thirteen patients (eight males and five females) aged 24 ± 5 years (range 16–35) were studied before and 12 and 24 months after GH treatment (0.1 IU, kg− day−1, 6 days a week). Serum levels of insulin-like growth factor I (IGF-I), calcitonin, parathyroid hormone, alkaline phosphatase, intact osteocalcin, fasting urinary hydroxyproline/creatinine ratio and bone mineral density (BMD), measured at the lumbar spine by dualphoton absorptiometry, were evaluated. After 12 months of treatment, IGF-I, alkaline phosphatase, osteocalcin and the fasting urinary hydroxyproline/creatinine ratio increased significantly. However, after 24 months of therapy, serum levels of osteocalcin decreased to pretreatment values while IGF-I, fasting urinary hydroxyproline/creatinine ratio and alkaline phosphatase remained elevated significantly. No changes were found in parathyroid hormone and calcitonin plasma levels or in BMD either after 12 or 24 months of treatment. These data demonstrate that GH, at the dosage that we used, activates bone turnover during 24 months of therapy in adults with panhypopituitarism, even if a downward trend for osteocalcin became apparent at 24 months. However, this activation in bone turnover was not accompanied by an increase in BMD. We can hypothesize that GH, at the relatively high dosage used, may stimulate osteoclastic activity to a greater extent than osteoblastic activity. It is probable that the dose of GH replacement therapy in adults plays a key role R Balducci, Dipartimento di Sanita Pubblica, Universita "Tor Vergata", Via di Tor Vergata 38, 00173 Roma, Italy

Periodontal Index

The association between osteoporosis and periodontal disease (PD) has been revealed by previous studies, but there have been few studies on the association in younger adults. We enrolled a total of 7298 adults aged 40 to 44 who underwent PD screening between 2003 and 2008. Data on quantitative ultrasound for the measurement of bone mineral density (BMD) were collected for the diagnostic criteria of osteopenia and osteoporosis. The Community Periodontal Index (CPI) was measured for defining PD. A multiple logistic regression model was used to assess the effect of low bone mass on the risk of PD. Of 7298 enrollees, 31% had periodontal pockets >3 mm, 36.2% had osteopenia, and 2.1% had osteoporosis. The 39.8% of PD prevalence was high in adults with osteoporosis, followed by 33.3% in osteopenia. A negative association was found between BMD and CPI value (p < 0.0001). Low bone mass was associated with the risk of PD (adjusted OR: 1.13; 95% CI:1.02–1.26) after adjusting the confounding factors, including age, gender, education level, overweight, smoking status, past history of osteoporosis, and diabetes mellitus. An association between BMD and PD among young adults was found. An intervention program for the prevention of PD and osteoporosis could be considered starting in young adults.

Abstract Background The organ toxicities of lead and cadmium have been extensively studied; however, studies of their toxic effects on bone remain limited, especially in young adults. The objective of this study was to examine the associations of blood lead levels (BLL) and blood cadmium levels (BCL) with bone mineral density (BMD) among young adults. Methods We performed a cross-sectional study using the National Health and Nutrition Examination Survey 2011–2018 database. Because of the skewed distribution, BLL and BCL were Ln-transformed for analysis. Weighted multivariate regressions were performed to evaluate the associations between LnBLL and LnBCL and lumbar BMD. Subgroup analyses were further performed. Results A total of 3234 participants aged 20–35 years were included in this study. No significant association between LnBLL and lumbar BMD was found (β = − 5.6, 95%CI: − 13.5–2.3). However, in the subgroup analysis stratified by sex, this association became negative in women (β = − 18.2, 95%CI: − 29.9– − 6.4). Moreover, this negative association was more prominent in female blacks (β = − 35.5, 95%CI: − 63.4– − 7.6). On the other hand, a negative association between LnBCL and lumbar BMD was found (β = − 7.4, 95%CI: − 14.0– − 0.8). In the subgroup analysis stratified by sex, this negative association only existed in women (β = − 18.7, 95%CI: − 28.0– − 9.5). Moreover, this negative association was more prominent in female whites (β = − 31.1, 95%CI: − 46.2– − 16.1). Conclusions Our finding showed that both BLL and BCL were independently and negatively associated with lumbar BMD among young females, but not among young males.

In this study, the authors have analyzed the possible effects of one-year adjuvant treatment with tamoxifen on bone mineral density in postmenopausal breast cancer women. Bone mineral content was studied by photon absorptiometry (I-125), whereas bone balance was analyzed indirectly by serum PTH, osteocalcin, calcitonin, calcium and alkaline phosphatase levels. Bone mineral content and serum bone-related substances were measured before starting treatment and after one year. Results were analyzed using Student's t test for paired data. No difference was found between the two measurements for bone mineral content, PTH, calcitonin, calcium and alkaline phosphatase levels. Measurements at entry and after one year of treatment showed a statistically significant difference ( P < 0.001) only for osteocalcin. In accordance with other authors, we can conclude that treatment with tamoxifen does not cause an increase in menopausal bone resorption. The finding that osteocalcin levels decreased after one year of therapy with tamoxifen is interesting, but further studies are necessary to clarify the role of such levels in predicting a turnover of bone balance towards osteoblastic activity.
