    PMID: 22892923
    OBJECTIVE: The objective of this study was to evaluate the effects of Tualang honey on trabecular structure and compare these effects with those of calcium supplementation in ovariectomized rats.

    METHODS: Forty female, Sprague-Dawley rats were randomly divided into five groups (n =8): four controls and one test arm. The control arm comprised a baseline control, sham-operated control, ovariectomized control, and ovariectomized calcium-treated rats (receiving 1% calcium in drinking water ad libitum). The test arm was composed of ovariectomized, Tualang honey-treated rats (received 0.2 g/kg body weight of Tualang honey). Both the sham-operated control and ovariectomized control groups received vehicle treatment (deionized water), and the baseline control group was sacrificed without treatment.

    RESULTS: All rats were orally gavaged daily for six weeks after day one post-surgery. The bone structural analysis of rats in the test arm group showed a significant increase in the bone volume per tissue volume (BV/TV), trabecular thickness (Tb.Th) and trabecular number (Tb.N) and a significant decrease in inter-trabecular space (Tb.Sp) compared with the ovariectomized control group. The trabecular thickness (Tb.Th) in the test arm group was significantly higher compared with the ovariectomized-calcium treated group, and the inter-trabecular space (Tb.Sp) in the test arm group was significantly narrower compared with the ovariectomized-calcium treated group.

    CONCLUSION: In conclusion, ovariectomized rats that received Tualang honey showed more improvements in trabecular bone structure than the rats that received calcium.

    Yeap SS, Othman AZ, Zain AA, Chan SP
    Int J Rheum Dis, 2012 Feb;15(1):17-24.
    PMID: 22324943 DOI: 10.1111/j.1756-185X.2011.01653.x
    AIM: To determine if baseline vitamin D levels would influence the gain in bone mineral density (BMD) in female systemic lupus erythematosus (SLE) patients on corticosteroids (CS) taking bone-active medication.

    METHOD: Premenopausal SLE patients participating in a trial assessing the efficacy of calcium alone, calcitriol and calcium, and alendronate and calcium, on BMD in patients on CS, were studied. Patients were randomly allocated to the treatment groups at the start of the study and followed up for 2 years. Serum 25-hydroxy vitamin D [25(OH)D] was measured at baseline.

    RESULTS:   Thirty-eight patients were studied. One (2%) patient had osteoporosis, nine (24%) had osteopenia and all others had normal BMD. The mean baseline 25(OH)D levels were 21.6 ± 4.6 ng/mL (± 1 SD). Twelve (32%) patients had vitamin D deficiency [25(OH)D < 20 ng/mL]. There was a significant negative correlation between SLEDAI scores and 25(OH)D levels, that is, patients with high SLEDAI scores had significantly lower 25(OH)D levels (P = 0.033). Left femoral neck BMD was significantly lower in the deficient compared to insufficient group (P = 0.042). There was a trend toward better BMD gain at 2 years in the vitamin D insufficient compared to the deficient group, which did not reach statistical significance.

    CONCLUSION: This study showed that in female SLE patients, low vitamin D levels are associated with higher disease activity and suggests that patients who have higher vitamin D levels have a better BMD response during treatment with bone-active agents.

  3. Management of corticosteroid-induced osteoporosis
    Yeap SS, Hosking DJ
    Rheumatology (Oxford), 2002 Oct;41(10):1088-94.
    PMID: 12364625 DOI: 10.1093/rheumatology/41.10.1088
    Corticosteroid (CS) therapy is widely used in the treatment of rheumatic diseases. Osteoporosis remains one of its major complications. The risk of low bone mineral density (BMD) and fracture may be already increased in some of the rheumatic diseases, regardless of CS therapy. However, in spite of this, preventative treatment for osteoporosis in patients on CS remains low. Patients on or about to start CS use for more than 6 months are at risk of corticosteroid-induced osteoporosis (CIOP). The pathogenesis of CIOP differs from post-menopausal osteoporosis in that bone formation is said to be more suppressed compared with bone resorption. The diagnosis of CIOP can be made on clinical risk factors and may not require measurement of BMD. Many agents used in post-menopausal osteoporosis such as activated vitamin D products, hormone replacement therapy, fluoride, calcitonin and the bisphosphonates have been shown to maintain or improve BMD in CIOP. However, there are few data on the reduction in fracture rates in CIOP, but the bisphosphonates seem the most promising in this regard.

  4. A comparison of calcium, calcitriol, and alendronate in corticosteroid-treated premenopausal patients with systemic lupus erythematosus
    Yeap SS, Fauzi AR, Kong NC, Halim AG, Soehardy Z, Rahimah I, et al.
    J Rheumatol, 2008 Dec;35(12):2344-7.
    PMID: 19004038 DOI: 10.3899/jrheum.080634
    OBJECTIVE: To assess bone mineral density (BMD) changes in patients with systemic lupus erythematosus (SLE) undergoing longterm therapy with corticosteroids (CS) while taking calcium, calcitriol, or alendronate. The primary endpoint was BMD changes at 2 years.
    METHODS: Premenopausal SLE patients were randomized into 3 groups according to medication: calcium carbonate 500 mg bd (calcium alone), calcitriol 0.25 microg bd plus calcium carbonate 500 mg bd (calcitriol + calcium), and alendronate 70 mg/week plus calcium carbonate 500 mg bd (alendronate + calcium). BMD was measured at baseline and at the end of the first and second years.
    RESULTS: Ninety-eight patients were recruited. There were 33 patients taking calcium alone, 33 calcitriol + calcium, and 32 alendronate + calcium. On randomization, median duration of CS use was 2.5 years (range 0-20 yrs). Seventy-seven patients (78.6%) completed the study (23 taking calcium alone, 27 calcitriol + calcium, 27 alendronate + calcium). There were no significant differences in mean CS dosages among the 3 groups at the time of BMD measurements. After 2 years, there were no significant changes in BMD in the calcium-alone and calcitriol + calcium groups, apart from a 0.93% (p < 0.001) reduction in total hip BMD in the calcium-alone group. In contrast, the alendronate + calcium group showed significant increases in BMD of 2.69% (p < 0.001) in the lumbar spine and 1.41% (p < 0.001) in total hip.
    CONCLUSION: Both calcium alone and calcitriol + calcium preserved lumbar spine BMD in premenopausal patients with SLE taking longterm CS at 2 years, whereas alendronate + calcium led to increases in BMD in lumbar spine and total hip. Premenopausal women taking CS should be considered for osteoporosis prophylaxis.

  5. Fulltext The Effects of Vitamin E from Elaeis guineensis (Oil Palm) in a Rat Model of Bone Loss Due to Metabolic Syndrome
    Wong SK, Chin KY, Suhaimi FH, Ahmad F, Ima-Nirwana S
    Int J Environ Res Public Health, 2018 08 24;15(9).
    PMID: 30149518 DOI: 10.3390/ijerph15091828
    The beneficial effects of vitamin E in improving components of MetS or bone loss have been established. This study aimed to investigate the potential of palm vitamin E (PVE) as a single agent, targeting MetS and bone loss concurrently, using a MetS animal model. Twelve-week-old male Wistar rats were divided into five groups. The baseline group was sacrificed upon arrival. The normal group was given standard rat chow. The remaining three groups were fed with high-carbohydrate high-fat (HCHF) diet and treated with tocopherol-stripped corn oil (vehicle), 60 mg/kg or 100 mg/kg PVE. At the end of the study, the rats were evaluated for MetS parameters and bone density. After euthanasia, blood and femurs were harvested for the evaluation of lipid profile, bone histomorphometric analysis, and remodeling markers. PVE improved blood pressure, glycemic status, and lipid profile; increased osteoblast surface, osteoid surface, bone volume, and trabecular thickness, as well as decreased eroded surface and single-labeled surface. Administration of PVE also significantly reduced leptin level in the HCHF rats. PVE is a potential agent in concurrently preventing MetS and protecting bone loss. This may be, in part, achieved by reducing the leptin level and modulating the bone remodeling activity in male rats.

    Wong SK, Mohamad NV, Jayusman PA, Shuid AN, Ima-Nirwana S, Chin KY
    Aging Male, 2019 Jun;22(2):89-101.
    PMID: 29508640 DOI: 10.1080/13685538.2018.1448058
    Selective estrogen receptor modulators (SERMs) represent a class of drugs that act as agonist or antagonist for estrogen receptor in a tissue-specific manner. The SERMs drugs are initially used for the prevention and treatment of osteoporosis in postmenopausal women. Bone health in prostate cancer patients has become a significant concern, whereby patients undergo androgen deprivation therapy is often associated with deleterious effects on bone. Previous preclinical and epidemiological findings showed that estrogens play a dominant role in improving bone health as compared to testosterone in men. Therefore, this evidence-based review aims to assess the available evidence derived from animal and human studies on the effects of SERMs on the male skeletal system. The effects of SERMs on bone mineral density (BMD)/content (BMC), bone histomorphometry, bone turnover, bone strength and fracture risk have been summarized in this review.

  7. Piper sarmentosum prevents glucocorticoid-induced osteoporotic bone resorption by increasing 11β-hydroxysteroid dehydrogenase type 1 activity
    Suhana MR, Farihah HS, Faizah O, Nazrun SA, Norazlina M, Norliza M, et al.
    Clin Ter, 2011;162(4):313-8.
    PMID: 21912818
    Osteoporosis is a proven complication of long-term glucocorticoid therapy. Concern on glucocorticoid induced osteoporosis has increased dramatically in recent years with the widespread use of synthetic glucocorticoids. Glucocorticoid action in bone depends upon the activity of 11βhydroxysteroid dehydrogenase type 1 enzyme (11βHSD1). This enzyme plays an important role in regulating corticosteroids by locally interconverting cortisone into active cortisol. This has been demonstrated in primary cultures of human, mouse or rat osteoblasts. Therefore, inhibition of this enzyme may reduce bone resorption markers. Piper sarmentosum (Ps) is a potent inhibitor of 11βHSD1 in liver and adipose tissue. In this study we determined the effect of Ps on 11βHSD1 activity in bones of glucocorticoid-induced osteoporotic rats.

  9. Vitamin E exhibits bone anabolic actions in normal male rats
    Shuid AN, Mehat Z, Mohamed N, Muhammad N, Soelaiman IN
    J. Bone Miner. Metab., 2010 Mar;28(2):149-56.
    PMID: 19779668 DOI: 10.1007/s00774-009-0122-2
    Recently, vitamin E has been found to promote the bone structure of nicotine-treated rats well above their baseline values, thus suggesting that vitamin E may have some anabolic action. A bone anabolic agent acts by improving the bone structure leading to stronger bone. To assess the possible anabolic action vitamin E on bone, we supplemented alpha-tocopherol (ATF) or gamma-tocotrienol (GTT) at 60 mg/kg or vehicle [normal control (NC) group] for 4 months to normal male rats and measured their bone structure and biomechanical properties. Histomorphometric analysis revealed that vitamin E-supplemented rats have better trabecular volume, thickness, number, and separation than rats receiving vehicle only. For the first time we reported that GTT improves all the parameters of bone biomechanical strength, while ATF only improved some of the parameters compared to the NC group. Vitamin E supplementation, especially with the gamma isomer, improves bone structure, which contributed to stronger bone. Therefore, vitamin E has the potential to be used as an anabolic agent to treat osteoporosis or as bone supplements for young adults to prevent osteoporosis in later years.

  10. Tocotrienols for bone health: a translational approach
    Shen CL, Klein A, Chin KY, Mo H, Tsai P, Yang RS, et al.
    Ann N Y Acad Sci, 2017 Aug;1401(1):150-165.
    PMID: 28891093 DOI: 10.1111/nyas.13449
    Osteoporosis, a degenerative bone disease, is characterized by low bone mass and microstructural deterioration of bone tissue resulting in aggravated bone fragility and susceptibility to fractures. The trend of extended life expectancy is accompanied by a rise in the prevalence of osteoporosis and concomitant complications in the elderly population. Epidemiological evidence has shown an association between vitamin E consumption and the prevention of age-related bone loss in elderly women and men. Animal studies show that ingestion of vitamin E, especially tocotrienols, may benefit bone health in terms of maintaining higher bone mineral density and improving bone microstructure and quality. The beneficial effects of tocotrienols on bone health appear to be mediated via antioxidant/anti-inflammatory pathways and/or 3-hydroxy-3-methylglutaryl coenzyme A mechanisms. We discuss (1) an overview of the prevalence and etiology of osteoporosis, (2) types of vitamin E (tocopherols versus tocotrienols), (3) findings of tocotrienols and bone health from published in vitro and animal studies, (4) possible mechanisms involved in bone protection, and (5) challenges and future direction for research.

    Gerodontology, 2016 Mar;33(1):135-43.
    PMID: 25039439 DOI: 10.1111/ger.12141
    OBJECTIVE: General medical and dental practitioner and pharmacists all encounter patients on bisphosphonates and as such require adequate knowledge regarding osteonecrosis of the jaw, a potential complication associated with its use. The cross-sectional study investigated perceived implications of and attitudes towards bisphosphonate use in oral health among general medical and dental practitioners and pharmacists.
    MATERIALS AND METHODS: Medical and dental practitioners and pharmacists registered in Victoria, Australia, completed an online survey (SurveyMonkey©). Data analysis consisted of chi-square tests with significance as p < 0.05.
    RESULTS: One hundred and thirty six doctors (general medical practitioners, GMPs), 283 dentists (GDPs) and 26 pharmacists (PHs) participated. 70, 38 and 80%, respectively, reviewed patients prescribed bisphosphonates (BPs). GMPs (88%), GDPs (76%) and PHs (85%) were aware of osteonecrosis of the jaws (ONJ). GMPs (76%) and PHs (100%) advised patients to inform dentists. GMPs (45%) referred patients for dental assessments prior to commencing BPs with 71.9% of GDPs received such referrals. In terms of available information on oral health and BPs, GMPs (56%), GDPs (50%) and PH (53.8%) were either unsure any existed or reported receiving sufficient information.
    CONCLUSIONS: Discrepancies exist amongst different healthcare professionals in terms of BP use and oral health, and common consensus guidelines are warranted.

  12. Fulltext A Review on the Role of Denosumab in Fracture Prevention
    Pang KL, Low NY, Chin KY
    Drug Des Devel Ther, 2020;14:4029-4051.
    PMID: 33061307 DOI: 10.2147/DDDT.S270829
    Denosumab is a receptor activator of nuclear factor kappa-Β ligand inhibitor, which suppresses the bone resorption process to preserve bone mass. It is usually recommended to postmenopausal women and men with high fracture risk. With the recent publication of the results from FREEDOM study and its extension, the long-term effect of denosumab in preventing fragility fractures has been put forward. This review aims at summarising the evidence of denosumab in reducing fracture risk and its safety derived from clinical studies. Most of the evidence are derived from FREEDOM trials up to 10 years of exposure. Denosumab is reported to prevent vertebral and non-vertebral fractures. It is also proven effective in Japanese women, patients with chronic kidney diseases and breast cancer patients receiving antineoplastic therapy. Denosumab discontinuation leads to high remodeling, loss of bone mineral density and increased fracture risk. These negative effects might be preventable by bisphosphonate treatment. The safety profile of denosumab is consistent with increased years of exposure. In conclusion, denosumab is a safe and effective option for reducing fracture risk among patients with osteoporosis.

  13. Fulltext A qualitative study of community pharmacists' opinions on the provision of osteoporosis disease state management services in Malaysia
    Nik J, Lai PS, Ng CJ, Emmerton L
    BMC Health Serv Res, 2016 08 30;16:448.
    PMID: 27577560 DOI: 10.1186/s12913-016-1686-x
    BACKGROUND: Osteoporosis has significant impact on healthcare costs and quality of life. Amongst the models for collaborative disease state management services published internationally, there is sparse evidence regarding the role of community pharmacists in the provision of osteoporosis care. Hence, the aim of our study was to explore community pharmacists' opinions (including the barriers and facilitators) and scope of osteoporosis disease state management services by community pharmacists in Malaysia, informing a vision for developing these services.

    METHODS: Semi-structured individual interviews and focus groups discussions were conducted with community pharmacists from October 2013 to July 2014. Three trained researchers interviewed the participants. Interviews were recorded and transcribed verbatim. Data were analyzed thematically using an interpretative description approach.

    RESULTS: Nineteen community pharmacists with 1-23 years of experience were recruited (in depth interviews: n = 9; focus group discussions: n = 10). These participants reflected on their experience with osteoporosis-related enquiries, which included medication counseling, bone density screening and referral of at-risk patients. Key barriers were the lack of numerous factors: public awareness of osteoporosis, accurate osteoporosis screening tools for community pharmacists, pharmacists' knowledge on osteoporosis disease and medications, time to counsel patients about bone health, collaboration between pharmacists and doctors, and support from the government and professional body. The pharmacists wanted more continuing education on osteoporosis, osteoporosis awareness campaigns, a simple, unbiased osteoporosis education material, and inter-professional collaboration practices with doctors, and pharmacists' reimbursement for osteoporosis care.

    CONCLUSIONS: The involvement of community pharmacists in the provision of osteoporosis disease state management was minimal. Only ad-hoc counseling on osteoporosis prevention was performed by community pharmacists. Development and trial of collaborative osteoporosis disease state management services in community pharmacy could be facilitated by training, support and remuneration.

    The present review explored the anti-inflammatory and immunomodulatory properties of vitamin E, which has protective action against osteoporosis. A systematic review of the literature was conducted to identify the published bone studies on vitamin E. The studies included inflammatory or immunology-related parameters. Medline and Scopus databases were searched for relevant studies published from 2005 till 2015. Research articles published in English and confined to the effect of vitamin E on bone were included. It is pertinent to mention that these studies took into consideration inflammatory or immunology parameters including interleukin (IL)-1, IL-6, receptor activator of nuclear factor kappa-B ligand (RANKL), inducible nitric oxide synthases (iNOS), serum amyloid A (SAA), e-selection and high-sensitivity C-reactive protein (hs-CRP). An extended literature search yielded 127 potentially relevant articles with seven articles meeting the inclusion and exclusion criteria. Another recent article was added with the total number accounting to eight. All these included literature comprised five animal studies, one in-vitro study and two human studies. These studies demonstrated that vitamin E, especially tocotrienol, was able to alleviate IL-1, IL-6, RANKL, iNOS and hs-CRP levels in relation to bone metabolism. In conclusion, vitamin E exerts its anti-osteoporotic actions via its anti-inflammatory and immunomodulatory effects.

    Nicotine is one of the most abused substances worldwide and can cause several harmful effects on health. One of the harmful effects, which is often ignored, is osteoporosis. Smoking has been shown to cause a decrease in bone mineral density in humans. Animal studies have proven that nicotine exerts negative effects on bone. The number of people who smoke increases each day. Those who smoke start at a very young age and they usually smoke for years. This will increase the risk of developing osteoporosis. As the prevalence of osteoporosis increases, the risk of fractures also increases. The major concerns are disability following fractures, mortality due to complications after fractures and the increasing cost of management and therapy. This paper will review the effects of nicotine on bone and the potential natural products which can be used as treatment for nicotine-induced osteoporosis.

  16. Fulltext Effect of tocotrienol from Bixa orellana (annatto) on bone microstructure, calcium content, and biomechanical strength in a model of male osteoporosis induced by buserelin
    Mohamad NV, Ima-Nirwana S, Chin KY
    Drug Des Devel Ther, 2018;12:555-564.
    PMID: 29588572 DOI: 10.2147/DDDT.S158410
    Background: Patients receiving androgen deprivation therapy experience secondary hypogonadism, associated bone loss, and increased fracture risk. It has been shown that tocotrienol from Bixa orellana (annatto) prevents skeletal microstructural changes in rats experiencing primary hypogonadism. However, its potential in preventing bone loss due to androgen deprivation therapy has not been tested. This study aimed to evaluate the skeletal protective effects of annatto tocotrienol using a buserelin-induced osteoporotic rat model.

    Methods: Forty-six male Sprague Dawley rats aged 3 months were randomized into six groups. The baseline control (n=6) was sacrificed at the onset of the study. The normal control (n=8) received corn oil (the vehicle of tocotrienol) orally daily and normal saline (the vehicle of buserelin) subcutaneously daily. The buserelin control (n=8) received corn oil orally daily and subcutaneous buserelin injection (75 µg/kg) daily. The calcium control (n=8) was supplemented with 1% calcium in drinking water and daily subcutaneous buserelin injection (75 µg/kg). The remaining rats were given daily oral annatto tocotrienol at 60 mg/kg (n=8) or 100 mg/kg (n=8) plus daily subcutaneous buserelin injection (75 µg/kg) (n=8). At the end of the experiment, the rats were euthanized and their blood, tibia, and femur were harvested. Structural changes of the tibial trabecular and cortical bone were examined using X-ray micro-computed tomography. Femoral bone calcium content and biomechanical strength were also evaluated.

    Results: Annatto tocotrienol at 60 and 100 mg/kg significantly prevented the deterioration of trabecular bone and cortical thickness in buserelin-treated rats (P<0.05). Both doses of annatto tocotrienol also improved femoral biomechanical strength and bone calcium content in buserelin-treated rats (P<0.05). The effects of annatto tocotrienol were comparable to calcium supplementation.

    Conclusion: Annatto tocotrienol supplementation is effective in preventing degeneration of the bone induced by buserelin. Therefore, it is a potential antiosteoporotic agent for men receiving androgen deprivation therapy.

    PMID: 18551949 MyJurnal
    The incidence of osteoporosis is increasing worldwide. It has great impact on the life of the elderly population. The most significant medical consequence of osteoporosis is fragility fracture which without proper treatment will cause severe medical and psychosocial complications. The overall cost in managing osteoporosis and its related fractures is escalating. Using bone densitometry to measure bone mineral density is useful in the diagnosis of osteoporosis but it is costly and not feasible in the community. Drugs such as estrogen replacement, raloxifene and calcitonin are effective in prevention and treatment of osteoporosis but they are also expensive. Identifying modifiable risk factors such as smoking, lack of exercise, low dietary calcium and vitamin D intake and healthy life style remain strategy in the primary prevention of osteoporosis in the community.

    Osteoporosis is a silent disease and becomes clinically significant in the presence of fragility fracture. Identifying risk factors that are associated with osteoporosis in the community is important in reducing the incidence of fragility fracture. The aim of this study is to identify risk factors associated with fragility fracture in the Seremban District of Malaysia. This is a population comparison study between orthopedic ward patients and outpatients attending a community health clinic for 6 months. Epidemiological data and the possible risk factors for osteoporosis were collected by direct interview. This study demonstrates that advancing age, low body weight, smoking, lack of regular exercise, low consumption of calcium containing foods, and using bone depleting drugs (steroids, thyroid hormone, and frusemides) are major risk factors for fragility fracture. Most of these risk factors are modifiable through effective lifestyle intervention.

    The aim of this study was to identify risk factors associated with osteoporosis in urban midlife Malaysian women and to assess the effectiveness of lifestyle intervention in bone loss prevention with hormone replacement therapy (HRT) as a positive control. A total of 514 disease-free, uterus-intact, non-HRT-using women aged 45 years and older were recruited into the study. After initial bone mineral density (BMD) assessments, they were randomized into three groups: GI (control), G2 (lifestyle intervention), and G3 (lifestyle intervention with HRT). The study group was composed of 67.5% Chinese, 27.8% Malay, and 4.2% Indians with a mean age of 51.07+/-5.28 years. Two-fifths were postmenopausal, and the prevalence of osteoporosis was 24.1%, seen predominantly at the hip. Postmenopausal women had significantly lower mean BMD and a higher incidence of osteoporosis compared with the premenopausal women, 42.1% vs. 11.1% (p<0.0005). A lower incidence of osteoporosis was found in women who took calcium supplementation regularly as opposed to those who do not, 18.7% vs. 29.3% (p=0.036). Age and a greater postmenopausal duration showed a significant negative association with BMD, whereas higher family income, weight, body mass index, and waist and hip circumference were positively correlated. After 18-20 months, the effect of intervention was assessed based on BMD values of 279 women at baseline and after intervention. Lifestyle intervention alone was effective in premenopausal women, preventing over 90% of spinal bone loss compared with the controls, who lost 11.6% (0.046 g/cm2) bone mass with similar losses of hip bone, 2.0% (0.026 g/cm2) vs. 1.5% (0.020 g/cm2). Premenopausal women on HRT also showed a substantial decrease in spine and hip BMD, 18.6% (0.081 g/cm2) and 9.0% (0.122 g/cm2), respectively. The lifestyle intervention program retarded postmenopausal bone loss by 21% and 37% compared with controls, who lost 9.6% (0.141 g/cm2) and 6.0% (0.138 g/cm2) bone mass at the spine and hip. In comparison, lifestyle intervention with HRT increased postmenopausal BMD by 12.7% (0.216 g/cm2) at the spine and 1.9% (0.042 g/cm2) at the hip. The changes in hip BMD were influenced by current age, ethnicity, and income, while intervention had the strongest effect on spine BMD changes. In conclusion, lifestyle intervention prevented spinal bone loss in premenopausal women and retarded postmenopausal spine and hip bone loss compared with controls. The benefits of physical activity on spine and hip BMD highlight its potential as a safe and cost-effective alternative to HRT, which is not advocated because of its potential adverse effects.

    The link between HIV and reduced bone mineral density, including osteopenia and the more severe osteoporosis, is well established. HIV infection has also been associated with an increased risk of fractures. It is so far unclear whether this is due to HIV itself, resulting inflammatory and metabolic changes, antiretroviral toxicity, or some combination of factors. This topic was the focus of major debate at the 7th IAS Conference held in Kuala Lumpur, Malaysia, in early July 2013.
