Background: The indication of denosumab for osteoporosis was expanded from second-line to first-line therapy in 2019. The aim of this study was to evaluate the efficacy of denosumab as both first- and second-line therapy in postmenopausal women with osteoporosis and osteopenia with risk factors by using the Fracture Risk Assessment Tool (FRAX). Methods: We conducted a medication use evaluation of denosumab in 98 patients who had been treated three or more times for osteoporosis or osteopenia at Chungnam National University Hospital from July 1^st, 2017 to January 31^st, 2020. Risk factors were identified using quantitative N-gram analyses of FRAX estimations. Patient information, including menopause status and results of bone mineral density tests (T-score), was obtained from electronic medical records. Results: Age, body mass index (BMI), prior medication use, and T-score were identified as risk factors and were included as variables in the evaluation of denosumab use. Since no significant differences were detected between groups, denosumab is likely effective regardless of age or BMI. In addition, no significant difference was detected in T-scores following denosumab treatment, between groups who took bisphosphonates and selective estrogen receptor modulators (SERMs) with denosumab as first-line therapy for postmenopausal osteoporosis. Denosumab may, therefore, be effective as second-line therapy. Conclusion: Efficacy of denosumab was evaluated in postmenopausal women with osteoporosis. Denosumab may be used as first- and second-line therapy regardless of age, BMI, and prior use of bisphosphonates and SERMs.

Osteoporosis is a disease that increases the fracture rates and a major cause of increased mortality and morbidity in the elderly people. This study is to determine which components of body composition and metabolic syndrome risk factors are important to bone health, we analysed the relationship among bone mineral density (BMD), body composition and metabolic syndrome risk factors in females. Totally 630 females participated in a medical check-up program (mean age 47 years) were selected for this study. Body composition analysis was performed by segmental bioelectrical impedance method, muscle mass, and percent body fat were measured. We also measured metabolic syndrome risk factors including abdominal obesity, HDL-cholesterol, triglyceride, blood pressure and fasting glucose level. Metabolic syndrome was defined by NCEP-ATP III criteria. The lumbar spine and femoral neck BMD were measured using the dual energy X-ray absorptiometry. Osteopenia and osteoporosis were observed in 180 and 51 persons, respectively. Muscle mass and HDL-cholesterol decreased in osteopenia and osteoporosis groups compared to the control group, and the grade was shown progressively by the symptoms. Significant positive correlation between BMD and muscle mass was observed. Multi variable regression analyses showed that % body fat and muscle mass were independent predictors of BMD after adjustment of age, height and weight. In conclusion, the BMD showed negative correlation with the metabolic and body composition was associated with BMD.

Background: Botulinum toxin injection on the masticatory muscle induces the osteopenic condition on the ipsilateral condyle. Bisphosphonate suppresses bone resorption and is used to treat osteopenic or osteoporotic condition. This study aimed to evaluate the effect of bisphosphonate administration on prevention of condylar resorption and botulinum toxin A-induced disuse osteopenia in rats. Results: The volume of the condyle and bone volume/tissue volume (BV/TV, %) showed a strong tendency towards statistical significance (p = 0.052 and 0.058). Trabecular thickness (Tb.Th, mm) and trabecular number (Tb.N, 1/mm) were significantly smaller in the Botox group than in the other groups (p < 0.05). The volume of the condyle and BV/TV in the bisphosphonate 100 and bisphosphonate 200 groups showed similar values when compared with the control group. Conclusion: Bisphosphonate administration after botulinum toxin A injection in the masticatory muscles appears to prevent condyle resorption and botulinum toxin-induced disuse osteopenia in rats.

Objective : To identify the risk factors for postmenopausal osteoporosis in Korea Materials and methods : Bone mineral density (BMD) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry in 808 apparently normal postmenopausal Korean women. Questions about life style, demographic parameters, medical history and social habits etc. were asked on these women; 2ll women with normal bone mineral density, and 597 women with osteopenia or osteoporosis. Results 'Age of >50 years, low body mass index (BMI; <18.5 kg/m2), long duration of menopause(>10 years), and previous history of fracture were associated with increased prevalence of osteopenia or osteoporosis. Women without the outside activity also showed a higher frequency of low bone mass, Risk for osteopenia or osteoporosis was low in women with high BMI (>23 kg/m2) and women with job. The prevalence of low bone mass appeared to be independent of the following parameters: socioeconomic status, familial history, smoking, drinking, exercise, previous use of oral contraceptive, coffee or milk consumption, and degree of sunlight exposure. Conclusion 'Age, BMI, duration of menopause, previous history of fracture and degree of outside activity are the risk factors for postmenopausal osteoporosis in Korea.

Objectives: Low bone density (LBD) in the postmenopausal period has long been a pervasive public health concern; however, the association between parity and LBD has yet to be fully elucidated. Thus, we investigated the association between parity and LBD in postmenopausal Korean women. Methods: This study used baseline data from 1287 Korean postmenopausal women aged 40 years or older enrolled in the Cardiovascular and Metabolic Diseases Etiology Research Center community-based cohort study conducted in Korea from 2013 to 2017. The main exposure was parity (nullipara, 1, 2, 3+). The main outcome was LBD, including osteopenia and osteoporosis, based on bone mineral density measured using quantitative computed tomography of the lumbar spine (L1-2). Results: The mean age of participants was 57.1 years, and the median parity was 2. Of the 1287 participants, 594 (46.2%) had osteopenia and 147 (11.4%) had osteoporosis. No significant difference in the prevalence of LBD was found between nullipara and parous women, whereas higher parity was associated with a higher risk of LBD among parous women; the adjusted odds ratio (95% confidence interval) for the presence of LBD was 1.40 (0.97 to 2.02) for a parity of 2 and 1.95 (1.23 to 3.09) for a parity of 3 relative to a parity of 1. Conclusions: Women who have given birth multiple times may be at greater risk of bone loss after menopause; therefore, they should be a major target population for osteoporosis prevention.

목적: 이중 에너지 X선 흡수 계측(DEXA, Dual Energy X-ray Absorptiometry)을 이용한 골다공증 진단 시 부위 별로 골다공증에 대한 진단 불일치도를 파악하고, 연령의 증가에 따른 골다공증 진단 일치 여부를 조사하여 골절 예방과 치료에 대한 기초 자료를 제공하고자 하였다. 연구대상 및 방법: 골절 및 정형외과적 수술이 없는 여성 220명을 대상으로 요추부 $1{\sim}4$번과 고관절의 대퇴경부, Ward's triangle 그리고 전완부의 Ultra digital 부위의 골밀도를 측정하였다. 요추부와 대퇴경부, 전완부의 진단 일치 여부를 위해 각 부위 별 골감소증, 골다공증을 구별하여 분석하였고, 연령의 증가에 따른 진단의 불일치도를 파악하였다. 통계처리는 전완부와 대퇴 경부, 요추부 골밀도의 상관분석을 하였고, 각 부위 T-score 비교는 $x^2$-test를 사용하여 유의성 검정을 하였고, p < 0.05인 경우를 유의한 차이로 판정하였다. 결과: 대상자의 요추부 골밀도는 정상이 57명(25.9%), 골감소증군 86명(39.1%), 골다공증군은 77명(35.0%)이었다. 요추 4번에서는 골다공증군이 78명(35.5%)이었고, Ward's triangle은 126명(57.3%)에서 골다공증으로 진단되어 Ward's triangle에서 골밀도가 가장 낮았다. 요추부와 대퇴경부의 진단불일치율은 57%였고, 요추부와 전완은 43%, 전완과 대퇴경부는 51%로 나타났다. 정상군, 골감소증군, 골다공증군의 진단불일치율은 각각 39%, 63%, 42%로 나타나, 골감소증군에서 진단불일치율이 가장 높았다. 요추부가 정상일 때 불일치도는 30대, 40대, 50대, 60대, 70대에서 각각 25%, 23%, 11%, 65%, 86%로 나타나 60대 이후 불일치도가 급격히 높아졌다. 요추부가 골감소증이나 골다공증일 때는 30대, 40대, 50대, 60대, 70대에서 각각 62%, 55%, 36%, 20%, 9%로 나타나 연령이 높아질수록 불일치도는 낮아졌다. 결론: 골밀도는 연령증가에 따라 변화되고 부위에 따라 서로 차이가 있으므로 골밀도 검사는 요추와 대퇴경부, 전완을 각각 측정하여 차이를 살펴보는 것이 바람직하다. 진단의 불일치 정도가 60대와 70대, 그리고 골다공증군에서 가장 현저하였으며, 이는 두 부위 이상에서 불일치가 일어날 가능성이 있으므로 골절 위험 한계치의 측정에 각 부위별 골밀도 측정이 필요할 것으로 사료된다.

This study examined the relationship between bone mineral density and DITI in the diagnosis of osteoporosis. An analysis was performed on the thermographic findings of 20 patients without osteoporosis, 20 with osteopenia and 20 with osteoporosis at the Kangnam Korean Hospital, KyungHee University, Seoul, Korea, from June 1998 to February 1999. The osteoporosis was measured by LUNAR PIXI and the body temperature was assessed by DITI. Thermogrphic measurements were performed on 4 areas(acupuncture point: CV12, CV4, BL23 and BL26). All data were coded for computer analysis and significances were tested by Duncan test. There was no significant difference in age among the three groups of patients. DITI revealed the significant hypothermia (p<0.001) on the osteoporosis patients compared with osteopenia and normal bone density patients. It is believed that DITI may be a favorable alternative to the diagnosis of osteoporosis.

골감소증 환자의 혈청중에 존재하는 IGFBP-5의 존재와 변화를 검토한 결과, 골감소즈 환자에서는 정상 대조군에 비해 IGFBP-5가 감소하였는데 이 변화는 IGFBP-5의 분해효소가 작용하기 때문인 것으로 나타났다. IGFBP-5에 작용하는 단백질분해효소 저해제중 metallo계인 EDTA 및 1,10-phenanthroline과 seriner계인 aprotinin, heparin, heparin cofactor 2(HC2), heparine+HC2가 IGFBP-5에 대해 저해효과가 크므로 metalloprotease이면서 serine protease의 성질을 가지는 효소들이 IGFBP-5에 작용하였다. IGF-I과 IGF-II 그리고 insulin은 효소 활성에 아무런 영향이 없었다. IGFBP-5의 zymography에서 정상인과 골감소증 환제어서 180 kDa 크기의 band가 나타났고, gelatin zymography에서 정상 대조군의 경우 66 kDa과 97 kDa 정도의 band가 확인되었고 골감소증 환자의 경우는 69 kDa의 band가 확인되었다.

This study investigated factors affecting the bone mineral density (BMD) of Korean young adult women (20~30 yrs) living in Seoul, according to the state of employment. Data on BMD and anthropometric and biochemical measurements were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) (2010~2011). BMD of the working group (WG) was generally higher than that of the non-working group (NWG). The prevalence of osteopenia, and osteoporosis between the groups was 29.0/31.5%, and 12.9/18.5% from 20~29 yrs as well as 25.5/24.1%, and 20.2/20.5% from 30~39 yrs, respectively. From 20~29 yrs, prevalence of osteopenia and osteoporosis in the WG was lower than that of the NWG. Alkaline phosphatase activity of the WG was lower than that of the NWG. In the WG, from 20~29 yrs, total femur BMD showed significant positive correlations with waist circumstance and BMI. In the NWG, from 20~29 yrs, total femur, femoral neck, and lumbar spine BMDs showed significant positive correlations with weight and fat mass, whereas they showed significant negative correlations with vitamin D. In the WG, from 30~39 yrs, total femur and femoral neck BMDs showed significant positive correlations with weight and free fat mass. The results of this study show that BMD of young adult women is insufficient regardless of their employment status. Therefore, practical and systematic programs are required to improve the BMD of young adult women as well as to maintain healthy bone levels.
