  1. Vitamin D levels: its relationship to bone mineral density response and disease activity in premenopausal Malaysian systemic lupus erythematosus patients on corticosteroids
    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.

  2. 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.

    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.

    Clin Rheumatol, 2007 Feb;26(2):182-5.
    PMID: 16565892 DOI: 10.1007/s10067-006-0258-6
    The primary objective of this study was to determine the relationship between dietary calcium intake and bone mineral density (BMD) in premenopausal women with systemic lupus erythematosus (SLE) on corticosteroids (CS). The secondary aim was to identify other risk factors for osteoporosis in these patients. A cross-sectional sample of patients attending the SLE Clinic at a teaching hospital was recruited. BMD was measured using dual-energy X-ray absorptiometry. Daily dietary calcium intake was assessed using a structured validated food frequency questionnaire, in which patients were asked to estimate their food intake based on their recent 2-month dietary habits. Sixty subjects were recruited with a mean age of 33.70+/-8.46 years. The median duration of CS use was 5.5 years (range 0.08-24). The median cumulative dose of steroids was 17.21 g (range 0.16-91.37). The median daily dietary calcium intake was 483 mg (range 78-2101). There was no significant correlation between calcium intake and BMD, even after correcting for CS use. There were also no correlations between BMD and the duration of SLE, cumulative CS use, duration of CS use, smoking, alcohol intake, and SLE disease activity index score. Twenty-eight (46.7%) patients had normal BMD, 28 (46.7%) had osteopenia, and four (6.6%) had osteoporosis. Duration of SLE significantly correlated with cumulative CS dosage. In conclusion, 6.7% of these Asian premenopausal SLE women had osteoporosis and only 46.7% had normal BMD. Daily dietary calcium intake did not correlate with BMD.

    Proton-pump inhibitors (PPI) and histamine-2 receptor antagonists (H2RA) are common acid suppressants used in gastrointestinal disorders. The trend of usage in Malaysia has changed from predominantly H2RA to PPI from 2007 to 2008, 3.46 versus 2.87 and 2.99 versus 3.24 DDD (Defined Daily Dose)/1000 population/day respectively. This raises concerns as PPI overutilization amounts to higher cost expenditure and are associated with various untoward consequences such as Clostridium difficile-associated diarrhea, pneumonia, and osteoporosis.

  5. Fulltext Probiotics (Bifidobacterium longum) Increase Bone Mass Density and Upregulate Sparc and Bmp-2 Genes in Rats with Bone Loss Resulting from Ovariectomy
    Parvaneh K, Ebrahimi M, Sabran MR, Karimi G, Hwei AN, Abdul-Majeed S, et al.

    Probiotics are live microorganisms that exert beneficial effects on the host, when administered in adequate amounts. Mostly, probiotics affect the gastrointestinal (GI) tract of the host and alter the composition of gut microbiota. Nowadays, the incidence of hip fractures due to osteoporosis is increasing worldwide. Ovariectomized (OVX) rats have fragile bone due to estrogen deficiency and mimic the menopausal conditions in women. Therefore, this study aimed to examine the effects of Bifidobacterium longum (B. longum) on bone mass density (BMD), bone mineral content (BMC), bone remodeling, bone structure, and gene expression in OVX rats. The rats were randomly assigned into 3 groups (sham, OVX, and the OVX group supplemented with 1 mL of B. longum 10(8)-10(9) colony forming units (CFU)/mL). B. longum was given once daily for 16 weeks, starting from 2 weeks after the surgery. The B. longum supplementation increased (p < 0.05) serum osteocalcin (OC) and osteoblasts, bone formation parameters, and decreased serum C-terminal telopeptide (CTX) and osteoclasts, bone resorption parameters. It also altered the microstructure of the femur. Consequently, it increased BMD by increasing (p < 0.05) the expression of Sparc and Bmp-2 genes. B. longum alleviated bone loss in OVX rats and enhanced BMD by decreasing bone resorption and increasing bone formation.

    PMID: 24326643
    The aim of this study was to determine the effects of palm oil-derived vitamin E on glucocorticoid-induced osteoporosis. Three-month old male Wistar rats were adrenalectomised to remove circulating glucocorticoids. The animals were then administered with Dexamethasone 120 µg/kg body weight/day. Treatment with palm vitamin E 60 mg/kg body weight/day was given simultaneously. The results showed that palm vitamin E prevented the loss in regional and whole body bone mineral density seen in the Dexamethasone treated animals. Palm vitamin E improved femoral length and calcium content in the Dexamethasone treated animals. The results confirmed that palm oil-derived vitamin E was effective in preventing glucocorticoid-induced osteoporosis.

    PMID: 12915959
    Dietary studies often report low calcium intake amongst post-menopausal Malaysian women and calcium deficiency has been implicated as part of the etiology of age-related bone loss leading to osteoporosis. Therefore, the objective of this study was to examine the effectiveness of high calcium skimmed milk (Anlene Gold, New Zealand Milk, Wellington, New Zealand) to reduce bone loss in Chinese postmenopausal women. Two hundred subjects aged 55-65 years and who were more than 5 years postmenopausal were randomized to a milk group and control group. The milk group consumed 50 g of high calcium skimmed milk powder daily, which contained 1200 mg calcium (taken as two glasses of milk a day). The control group continued with their usual diet. Using repeated measures ANCOVA, the milk supplement was found to significantly reduce the percentage of bone loss at the total body compared to the control group at 24 months (control -1.04%, milk -0.13%; P<0.001). At the lumbar spine, the percentage of bone loss in the control group was significantly higher (-0.90%) when compared to the milk (-0.13%) supplemented group at 24 months (P<0.05). Similarly, milk supplementation reduced the percentage of bone loss at the femoral neck (control -1.21%, milk 0.51%) (P<0.01) and total hip (control -2.17%, milk -0.50%) (P<0.01). The supplemented group did not experience any significant weight gain over the 24 months. The serum 25-hydroxy vitamin D level improved significantly (P<0.01) from 69.1 +/- 16.1 nmol/l at baseline to 86.4 +/- 22.0 nmol/l at 24 months in the milk group. In conclusion, ingestion of high calcium skimmed milk was effective in reducing the rate of bone loss at clinically important lumbar spine and hip sites in postmenopausal Chinese women in Malaysia. Supplementing with milk had additional benefits of improving the serum 25-hydroxy vitamin D status of the subjects.

    Risk factors of osteoporosis need to be identified for prevention of osteoporosis. However, studies on the risk factors of osteoporosis in the Malaysian population are lacking. The study aimed to determine the relationship between potential risk factors of osteoporosis and hip BMD of postmenopausal women in a Malaysian tertiary hospital setting. A cross-sectional study was carried out on 76 postmenopausal women, who were scheduled for Dual-energy X-ray Absorptiometry (DXA) scan at UKM Medical Centre (UKMMC) from February to May, 2014. Interview sessions using structured questionnaire were conducted to obtain information on social demographic and potential risk factors of osteoporosis. The DXA scan results of the hip BMD for all the respondents were recorded to determine the association between the potential risk factors of osteoporosis and hip BMD. In this study, 44.7% of patients had normal hip BMD measurement (T score >-1.0), while 55.3% had low hip BMD measurement (T score0.05) between hip BMD and family history of osteoporosis, lifestyle activities and smoking. Parity, habitual tea consumption and BMI were positively associated with hip BMD, whereas duration of sleep was negatively associated with hip BMD among postmenopausal women in UKMMC. © 2014 Asian Network for Scientific Information.

    J Tradit Complement Med, 2019 Oct;9(4):393-400.
    PMID: 31453136 DOI: 10.1016/j.jtcme.2019.01.002
    Background: Marantodes pumilum var. alata (MPva), popularly known as Kacip Fatimah, is widely used to maintain female reproductive health, facilitate post-partum recovery and manage symptoms of menopause and osteoporosis in South-East Asia. This study aims to further evaluate the osteoprotective potential of MPva in view of reports of its bone-protective properties in postmenopausal condition.

    Methods: Thirty female Sprague-Dawley rats were sorted into 5 groups (n = 6) namely: MPv (leaf treatment); MPr (root treatment); ERT (estrogen treatment); OVXC (untreated ovariectomized control) and Sham (untreated sham-operated control). All rats (except the Sham) were ovariectomized to induce a state of estrogen deficiency that simulates menopause. Two weeks after ovariectomy, the rats were treated for 8 weeks with oral gavages of estrogen and plant extracts. The ERT group received 64.5 μg/kg/day dose of estrogen while MPv and MPr groups received 20 mg/kg/day dose of leaf and root extracts, respectively. At the end of treatment, left femora were excised from euthanized rats and investigated for changes in bone micro-architecture, mineral density, and biomechanical properties.

    Results: Bone volume fraction, degree of anisotropy and structure-model-index of bone were significantly improved (p

    Mini Abstract: Pregnancy-associated osteoporosis (PAO) is a rare syndrome affecting women during late pregnancy and the early postpartum period. We set out to review the clinical features of ten cases of PAO from a single UK centre. Patients had attended the Royal National Hospital for Rheumatic Diseases, Bath (RNHRD) between January 2000 and June 2016. The principal criterion for inclusion was the occurrence of low trauma fractures either during pregnancy or the immediate post-partum period. Data were obtained from retrospective review of medical notes. Bone mineral density (BMD) was measured using dual-energy X-ray absorptiometry (Hologic ®Discovery system) at the lumbar spine and hip. Data pertaining to the pregnancy, as well as type and duration of treatment received, were reviewed. All ten cases presented with vertebral fractures. In four patients, no risk factors for fracture other than pregnancy or breastfeeding could be identified. Four patients were found to have vitamin D insufficiency at the time of diagnosis, and a further two patients had received treatment with low molecular weight heparin (LMWH). In one case, further investigation led to a diagnosis of osteogenesis imperfecta (OI) confirmed on genetic testing. In terms of treatment, eight out of the ten patients in this series received a bisphosphonate, most commonly risedronate due to its relatively short skeletal retention time. Clinicians should be aware of PAO, a rare but recognised complication of pregnancy. The condition should be especially considered in women presenting with new onset back pain in pregnancy or the postpartum period.

    Osteoporosis is commonly underdiagnosed and undertreated. We performed a clinical audit to assess the risk factors and clinical care for osteoporosis among older persons who attended medical clinic during a 4-week period in August 2013. There was a total of 128 patients with a mean age of 73.1±5.8 years, and 20.3%. had a history of fall. Fracture Risk Assessment Tool (FRAX) scores assessment showed 14.2% and 68.8% had a 10-year risk of major osteoporotic and hip fractures respectively. Only 6.3% underwent Dual-energy X-ray absorptiometry (DXA) and 73.4% did not receive any preventive treatment for osteoporosis. Older persons attending medical clinic at high risk of osteoporosis fractures did not receive appropriate screening and treatment. There is a need to improve the suboptimal care for bone health among older persons.

    Denosumab is a human monoclonal antibody that binds to RANKL (receptor activator of nuclear factor-kappa B ligand). It has mainly been used in the treatment of osteoporosis for a variety of causes especially in situations refractory to bisphosphonates or when kidney function is impaired. It is also used in cases of malignancy-associated hypercalcemia. There are many causes of hypercalcemia, but only rarely it is associated with granulomatous diseases such as tuberculous pleural effusion. We report a case of hypercalcemia from tuberculous pleural effusion that was initially admitted with left medium abundance pleural effusion and a serum corrected calcium level of 3.48 mmol/L. The calcium level was successfully normalized within 72 hours of subcutaneous denosumab administration after other interventions have failed.

    Introduction: Osteoporosis is a major health problem worldwide. In Asia, few studies have measured knowledge, attitude and practices (KAP) of osteoporosis. This study aimed to determine the KAP of osteoporosis, including the main factors influencing attitude towards osteoporosis, and the relationship between osteoporosis knowledge, attitude, and practices among adults in Kuala Lumpur, Malaysia.
    Methods: A cross-sectional study via a self-administrated KAP questionnaire was carried out among 232 respondents aged 21 to 50 years in Kuala Lumpur. Random sampling was applied to select five districts in Kuala Lumpur, while convenient sampling was used for recruitment of apparently healthy subjects from community and institutional settings. The data were analysed using Mann-Whitney, Kruskal-Wallis, Chi-Square, Spearman Correlation and multiple logistic regression tests.
    Results: The findings indicate a moderate level of knowledge and attitude towards osteoporosis prevention with median scores of 51.6% and 68.6%, respectively. Osteoporosis knowledge varied significantly with gender, educational level and household income (p<0.05). Furthermore, attitude was significantly different in relation to educational level and household income. Based on the multiple logistic regression test, relatives and friends appeared to be the most significant factor influencing attitude (R=0.319, p<0.0001). Poor dietary and lifestyles practices were indicated, and a significant relationship was found between practice of weight-bearing activities and educational level (p<0.05). A significant correlation was found (ρ=0.348, p<0.0001) between knowledge and attitude, while no relationship was noted between knowledge and practice of weight-bearing activities or attitude and practice of weight-bearing activities.
    Conclusion: Knowledge played a significant role in affecting attitudes towards osteoporosis. However, understanding of osteoporosis is still at a moderate level. Friends and family were the most influential factor.

    Ceramic materials play key role in several biomedical applications. One of them is bone graft which is use in treating bone defect which caused by injury or osteoporosis. Calcium phosphates based ceramic are preferred as bone grafts in hard tissue engineering because of their chemical compositions are similar to the composition of human bone, superior bioresorbable and bioactivity. In this study, β-tricalcium phosphate (β-TCP) ceramic was synthesized by using sol-gel method. Phosphorous pentoxide (P2O5) and calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) were used as calcium and phosphate precursors. The effects of calcination temperature on the synthesis powder were studied using the XRD, SEM-EDS and FTIR techniques. It was found that calcination temperature greatly influence the purity of the synthesized powders. The β-TCP was the dominant phase with the formation of α-TCP at calcination temperature from 600 to 800°C. Pure β-TCP was obtained at calcination of 900°C. As the temperature increased to 1000°C, the β-TCP was decomposed to for calcium phosphate oxide (CPO). The sol-gel method has some advantages over other methods, mainly its simplicity and ability to produce pure β-TCP at lower calcination temperature.

    Osteoporosis-related fractures have been recognized as a major health problem, particularly in the elderly with a high morbidity and mortality rate. The aims of the study were to identify knowledge and perception toward calcium intake among students at UiTM and to explore the differences between genders in dietary calcium intake. A cross sectional study was conducted through 336 students aged 18 to 34 years old. The participants were randomly chosen from the student’s enrolment list. A modified questionnaire was used to obtain the knowledge and perception of the participants. More than half of the participants have low knowledge regarding dietary calcium intake (58.6%), positive view towards the benefits of calcium intake and low perception towards the barrier of calcium intake. Chi square analysis showed a significant difference between male and female for knowledge (p=0.034) and barrier (p=0.002) for calcium intake. Intervention programs should be adopted to increase the knowledge among young adults to improve their health and prevent risk factors. So, health education specifically on calcium intake will be very useful to improve the knowledge and behavior of students.

    Milk-derived bioactive peptides have been identified as potential ingredients of health-promoting functional foods. These bioactive peptides are targeted at diet-related chronic diseases especially the non-communicable diseases viz., obesity, cardiovascular diseases and diabetes. Peptides derived from the milk of cow, goat, sheep, buffalo and camel exert multifunctional properties, including anti-microbial, immune modulatory, anti-oxidant, inhibitory effect on enzymes, anti-thrombotic, and antagonistic activities against various toxic agents. Majority of those regulate immunological, gastrointestinal, hormonal and neurological responses, thereby playing a vital role in the prevention of cancer, osteoporosis, hypertension and other disorders as discussed in this review. For the commercial production of such novel bioactive peptides large scale technologies based on membrane separation and ion exchange chromatography methods have been developed. Separation and identification of those peptides and their pharmacodynamic parameters are necessary to transfer their potent functional properties into food applications. The present review summarizes the preliminary classes of bioactive milk-derived peptides along with their physiological functions, general characteristics and potential applications in health-care.

    Osteoporosis reduces the skeletal strength and increases the risk for fracture. It is an underdiagnosed disease in men. Annatto tocotrienol has been shown to improve bone structural indices and increase expression of bone formation genes in orchidectomized rats. This study aimed to evaluate the effects of annatto tocotrienol on biomechanical strength and calcium content of the bone in orchidectomized rats. Thirty three-month-old male Sprague-Dawley rats were randomly assigned to five groups. The baseline control (BC) group was sacrificed at the onset of the study. The sham-operated group (SHAM) received olive oil (the vehicle of tocotrienol) orally daily and peanut oil (the vehicle of testosterone) intramuscularly weekly. The remaining rats were orchidectomized and treated with three different regimens, i.e., (1) daily oral olive oil plus weekly intramuscular peanut oil injection; (2) daily oral annatto tocotrienol at 60 mg/kg plus weekly intramuscular peanut oil injection; (3) daily oral olive oil plus weekly intramuscular testosterone enanthate injection at 7 mg/kg. Blood, femur and tibia of the rats were harvested at the end of the two-month treatment period for the evaluation of serum total calcium and inorganic phosphate levels, bone biomechanical strength test and bone calcium content. Annatto-tocotrienol treatment improved serum calcium level and tibial calcium content (p < 0.05) but it did not affect femoral biomechanical strength (p > 0.05). In conclusion, annatto-tocotrienol at 60 mg/kg augments bone calcium level by preventing calcium mobilization into the circulation. A longer treatment period is needed for annatto tocotrienol to exert its effects on bone strength.

    Osteoporosis is a global health problem both in the developed and developing countries. Patient education forms an important part in the management of osteoporosis. The objective of this study was to evaluate knowledge about osteoporosis and its correlates among women aged ≥ 40 years attending an urban health centre in India and to identify their sources of information on osteoporosis. Knowledge about osteoporosis was assessed using the Osteoporosis Questionnaire (OPQ) in 243 women over 40 years of age, attending an urban health centre in the city of Mumbai located in the state of Maharashtra in western India. This exploratory cross-sectional study was conducted over a period of eight months. The OPQ analysis was performed using SPSS for Windows Version 13.0. The scores were expressed as mean ± SD (Standard Deviation). The one sample-t test was used to study the differences in the mean scores between socio-demographic variables. The mean total OPQ score was 0.91 (SD ± 5; range -9 to 10; maximum possible score 20). There was a significant difference in the total OPQ scores by the level of education and family history of osteoporosis (p

    PMID: 25606283 MyJurnal
    Bisphosphonates are pyrophosphate analogues, with a strong affinity for bones. They inhibit bone resorption and are currently the first choice of treatment for osteoporosis. Bisphosphonates should be taken in a specific manner and for at least one year to be effective in the maintenance and improvement of bone mineral density (BMD), as well as for protection against fractures. We report a case of a postmenospausal osteoporotic woman who lost BMD despite being on bisphosphonate therapy for eight years, highlighting issues that a primary care doctor needs to address before deciding on the next best option.

    Oxidative stress has been associated with postmenopausal osteoporosis which pre-disposes to risk of fracture. Palm tocotrienol is a potent antioxidant and has the poten-tial to be used for treatment of post-menopausal osteoporosis. The aim of the study is to determine if palm tocotrienol supplementation could alleviate oxidative stress in ovariectomised rat model and improve its bone strength. The rats were di- vided into four groups: (i) sham-operated  group (SHAM) (ii) ovariectomised-control group (OVX) (iii) ovariectomised and given 60mg/kg α-tocopherol by oral gavage (OVX + ATF) (iv) ovariectomised and given 60mg/kg palm tocotrienols by oral gavage (OVX + PTT). After eight weeks of treatment, blood samples were taken to measure oxida-tive status (MDA, SOD and GPX) while the femurs were biomechanically tested for strength and resistance to fracture. Ovariectomy was shown to induce oxidative stress as shown by the raised MDA levels and reduced GPX activity. Palm tocotrienols seemed to offer protection against the ovariectomy-induced oxidative stress as shown by the suppression of MDA levels and raised GPX and SOD activities in the OVX+PTT group. In comparison, α-tocopherol was only able to raise the SOD but not as high as palm tocotrienols. The biomechanical tests have shown that ovariectomy has not af-fected the bone strength significantly after eight weeks. Palm tocotrienols supplemen-tation for eight weeks was effective in preventing oxidative stress in a post-meno-pausal rat.
