Abstract
INTRODUCTION To describe the real-world use of romosozumab in Japan, we conducted a chart review of > 1000 Japanese patients with osteoporosis (OP) at high risk of fracture, across multiple medical institutions. MATERIALS AND METHODS Treatment-naïve and prior OP-treatment patients who received romosozumab for 12 months followed by ≥ 6 months of sequential OP treatment were included. The primary objective described the baseline demographics and clinical characteristics; secondary objectives evaluated changes in bone mineral density (BMD) and bone turnover markers in all patients and effectiveness of romosozumab in a sub-group of treatment-naïve patients using the fracture risk assessment tool (FRAX®). RESULTS Of the 1027 patients (92.4% female), 45.0% were treatment-naïve. The mean ± SD age of treatment-naïve versus prior OP-treatment patients was 76.8 ± 8.5 and 77.1 ± 8.5 years. The most frequent prior OP treatment was bisphosphonates (45.0%). Romosozumab treatment for 12 months increased BMD at the lumbar spine in all groups; the median percent change from baseline in lumbar spine BMD was higher in the treatment-naïve (13.4%) versus prior OP-treatment group (bisphosphonates [9.2%], teriparatide [11.3%], denosumab [DMAb, 4.5%]). DMAb, bisphosphonates, or teriparatide after romosozumab maintained the BMD gains at all skeletal sites at month 18 in treatment-naïve patients. Most treatment-naïve patients were at high risk of fracture, BMD increased consistently with romosozumab regardless of the baseline fracture risk assessed by FRAX. CONCLUSION This large-scale, multicenter chart review provides clinically relevant insights into the profiles of patients initiating romosozumab, effectiveness of real-world romosozumab use, and sequential therapy in Japanese patients at high risk of fracture.

Abstract
Patients with osteoporosis and chronic kidney disease (CKD) are at increased risk of fracture and associated negative outcomes, including increased mortality. The present post hoc analysis of two randomized, multicenter, phase 3 clinical trials-Fracture Study in Postmenopausal Women with Osteoporosis (FRAME) and Active-Controlled Fracture Study in Postmenopausal Women with Osteoporosis at High Risk (ARCH)-investigated the efficacy and safety of romosozumab in postmenopausal women with osteoporosis and mild-to-moderate CKD. The analysis included data from 7147 patients from FRAME and 4077 from ARCH. Eighty-one percent of patients from FRAME and 85% from ARCH had mild or moderate reduction in estimated glomerular filtration rate (eGFR) at baseline, and part of this reduction is likely age related. During the 1-year double-blind phases of the trials, patients received romosozumab 210 mg sc or placebo monthly in FRAME and romosozumab 210 mg sc monthly or alendronate 70 mg po weekly in ARCH. Bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck and vertebral and nonvertebral fractures were assessed at baseline and month 12. In both trials, the least-square mean percent change from baseline BMD was significantly greater in the romosozumab groups versus controls across all kidney function categories at month 12. Romosozumab reduced the relative risk of new vertebral fractures at month 12 among patients with eGFR of 30-59, 60-89, and ≥90 mL/min by 72% (95% confidence interval [CI] 14-91; p = 0.017), 70% (40-85; p < 0.001), and 84% (30-96; p = 0.005), respectively, in FRAME versus placebo, and by 51% (5-75; p = 0.04), 19% (-28 to 49; p = 0.39), and 57% (1-81, p = 0.04), respectively, in ARCH versus alendronate. Incidences of adverse events, asymptomatic decreases in serum calcium, and evolution of kidney function during the studies were similar across all baseline kidney function groups. Romosozumab is an effective treatment option for postmenopausal women with osteoporosis and mild-to-moderate reduction in kidney function, with a similar safety profile across different levels of kidney function. © 2022 The Authors.

Abstract
INTRODUCTION This post hoc analysis of the placebo-controlled phase 3 FRAME study assessed the efficacy and safety of romosozumab in a subpopulation of Japanese postmenopausal women with osteoporosis and chronic kidney disease (CKD). MATERIALS AND METHODS Data were analyzed by baseline estimated glomerular filtration rate (eGFR), where < 90 mL/min/1.73 m2 denoted CKD and ≥ 90 mL/min/1.73 m2 indicated normal renal function. Efficacy outcomes included percent change in lumbar spine, total hip, and femoral neck bone mineral density (BMD) at 12 months from baseline (primary) and incidence of new vertebral and non-vertebral fractures. Tolerability was also assessed. RESULTS Of 489 Japanese patients with available eGFR data, 339 had mild-to-moderate CKD (romosozumab, n = 170; placebo, n = 169) and 150 had normal renal function (romosozumab, n = 75; placebo, n = 75). Compared with placebo, romosozumab increased lumbar spine BMD by 14.8% (95% confidence interval [CI] 13.7-15.9) and 15.2% (95% CI 13.4-16.9) in the eGFR < 90 and ≥ 90 mL/min/1.73 m2 subgroups, total hip BMD by 4.6% (95% CI 3.8-5.4) and 5.5% (95% CI 4.4-6.7), and femoral neck BMD by 4.0% (95% CI 2.9-5.2) and 5.5% (95% CI 3.8-7.1) at 12 months, respectively (all p < 0.001 vs. placebo). New vertebral fracture incidence was numerically lower with romosozumab than placebo at 12 months in both eGFR subgroups, while the incidence of adverse events was similar between subgroups. CONCLUSION Romosozumab for 12 months is an effective and well-tolerated treatment option for Japanese patients with osteoporosis and mild-to-moderate CKD.

Abstract
UNLABELLED To evaluate whether treatment sequence affects romosozumab response, this analysis reviewed studies where romosozumab was administered before or following an antiresorptive (alendronate or denosumab). Initial treatment with romosozumab followed by an antiresorptive resulted in larger increases in bone mineral density of both hip and spine compared with the reverse sequence. INTRODUCTION Teriparatide followed by an antiresorptive increases bone mineral density (BMD) more than using an antiresorptive first. To evaluate whether treatment sequence affects romosozumab response, we reviewed randomized clinical trials where romosozumab was administered before (ARCH, FRAME) or following (STRUCTURE, Phase 2 extension) an antiresorptive (alendronate or denosumab, respectively). METHODS We evaluated BMD percentage change for total hip (TH) and lumbar spine (LS) and response rates (BMD gains ≥ 3% and ≥ 6%) at years 1 and 2 (except STRUCTURE with only 1-year data available). RESULTS With 1-year romosozumab initial therapy in ARCH and FRAME, TH BMD increased 6.2% and 6.0%, and LS BMD increased 13.7% and 13.1%, respectively. When romosozumab was administered for 1 year after alendronate (STRUCTURE) or denosumab (Phase 2 extension), TH BMD increased 2.9% and 0.9%, respectively, and LS BMD increased 9.8% and 5.3%, respectively. Over 2 years, TH and LS BMD increased 7.1% and 15.2% with romosozumab/alendronate, 8.5% and 16.6% with romosozumab/denosumab, and 3.8% and 11.5% with denosumab/romosozumab, respectively. A greater proportion of patients achieved BMD gains ≥ 6% when romosozumab was used first, particularly for TH, versus the reverse sequence (69% after romosozumab/denosumab; 15% after denosumab/romosozumab). CONCLUSION In this study, larger mean BMD increases and greater BMD responder rates were achieved when romosozumab was used before, versus after, an antiresorptive agent. Since BMD on treatment is a strong surrogate for bone strength and fracture risk, this analysis supports the thesis that initial treatment with romosozumab followed by an antiresorptive will result in greater efficacy versus the reverse sequence.

Abstract
INTRODUCTION This post-hoc analysis of the FRAME study investigated the long-term efficacy and safety of romosozumab followed by denosumab in postmenopausal Japanese women with osteoporosis at high fracture risk. MATERIALS AND METHODS Data from Japanese women with a high fracture risk participating in the international, randomised, double-blind, placebo-controlled, phase 3 FRAME study were analysed. High risk of fracture was defined as ≥ 1 fragility fracture with bone mineral density (BMD) ≤ - 2.5 standard deviations [SD], > 2 prevalent vertebral fractures, prevalent semiquantitative grade 3 vertebral fracture, or lumbar spine BMD < - 3.3 SD. Endpoints included incidence of new vertebral fracture at 12, 24 and 36 months and percentage change from baseline in BMD at the lumbar spine, total hip and femoral neck. RESULTS 187 Japanese subjects at high risk of fracture were enrolled in FRAME. Incidence of new vertebral fractures was lower with romosozumab/denosumab vs. placebo/denosumab at 12, 24 and 36 months (relative risk reduction at all timepoints: 84%; p = 0.056). BMD increases at 12, 24 and 36 months were greater in subjects receiving romosozumab/denosumab than placebo/denosumab (lumbar spine: 16.3%, 21.5% and 23.2% vs 0.4%, 8.1% and 10.4%; total hip: 4.9%, 7.9% and 8.9% vs 0.4%, 2.8% and 4.1%; femoral neck: 4.8%, 7.6% and 8.1% vs 0.3%, 3.3% and 3.7%, respectively; all p < 0.001 vs placebo/denosumab). Adverse events were generally balanced between groups. CONCLUSION Romosozumab/denosumab in Japanese subjects at high risk of fracture resulted in significant BMD gains and numerically lower vertebral fracture rate vs. placebo/denosumab at all timepoints measured.

Abstract
Background:Osteoporosis and renal insufficiency are coexisting disease states in a substantial proportion of postmenopausal women. Since bisphosphonates are generally contraindicated in patients with estimated glomerular filtration rate (eGFR) <35 mL/min, it is important to evaluate other osteoporosis treatments in this setting.Objectives:To determine if baseline renal function affects the efficacy and safety of romosozumab.Methods:We performed post hoc analyses of two clinical trials of romosozumab in postmenopausal women with osteoporosis. In ARCH (NCT01631214), 4,093 patients were randomised 1:1 to romosozumab 210 mg monthly or alendronate 70 mg weekly for 12 months (mean age: 74.3 years; 96.1% with prevalent vertebral fractures [VFx]). In FRAME (NCT01575834), 7,180 patients were randomised 1:1 to romosozumab 210 mg or placebo monthly for 12 months (mean age: 70.9 years; 18.3% with prevalent VFx). For these analyses, patients were categorised by baseline eGFR (mL/min/1.73m2): normal renal function (eGFR ≥90), mild renal insufficiency (eGFR 60–89), or moderate renal insufficiency (eGFR 30–59). Least squares mean (LSM) percent change from baseline in bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck; incidence of new VFx and adverse events (AEs); and changes in renal function were assessed for each eGFR category at Month 12 of the double-blind treatment period.Results:At baseline, most patients had mild/moderate renal insufficiency: 84% in ARCH, 88% in FRAME. In both studies, change from baseline in BMD was significantly higher in the romosozumab group across baseline eGFR categories (Figure). There was an interaction between BMD increase and renal function, and although BMD increase was not as large in women with impaired renal function, differences between romosozumab and control groups remained significant (Figure). In ARCH, among patients with eGFR ≥90, 60–89, and 30–59, the incidence of new VFx (romosozumab vs alendronate) at Month 12 was 3.3% vs 7.3%, 3.2% vs 3.9%, and 3.4% vs 6.2% in ARCH. In FRAME, the incidence of new VFx (romosozumab vs placebo) at Month 12 was 0.5% vs 3.0%, 0.4% vs 1.5%, and 0.6% vs 2.1%.In both studies, the incidences of AEs and serious AEs were similar in both treatment groups within and across eGFR categories. AEs of mild-to-moderate hypocalcaemia (investigator reported) occurred in two patients in ARCH (one romosozumab [eGFR 60–89] and one alendronate [eGFR ≥90]), and one patient in FRAME (romosozumab [eGFR 60–89]). Five patients in ARCH (all in the alendronate group) and 19 patients in FRAME (14 romosozumab, 5 placebo) had decreases in serum Ca levels (albumin adjusted); in the romosozumab group all were mild (<LLN–8.0 mg/dL) or moderate (<8.0–7.0 mg/dL). A similar percentage of patients in each group had changes in renal function over 12 months of treatment.Conclusion:The efficacy and safety of romosozumab vs alendronate or placebo was similar among postmenopausal women with osteoporosis and different levels of renal function.Acknowledgments:This study was funded by Amgen, Astellas and UCB Pharma.

Abstract
INTRODUCTION Procollagen type I N-terminal propeptide (P1NP), a bone formation marker, reportedly predicts bone mineral density (BMD) response to teriparatide treatment in treatment-naive patients with osteoporosis. Results from a randomized, phase 3, open-label, active-controlled trial- STRUCTURE-showed that in patients previously treated with bisphosphonates, romosozumab led to gains in hip BMD, which were not observed with teriparatide. This post hoc analysis investigated the comparative utility of early changes in P1NP in predicting BMD response in patients who participated in the STRUCTURE trial, which enrolled patients who switched treatment from bisphosphonates to romosozumab/teriparatide. MATERIALS AND METHODS Postmenopausal women (aged 55-90 years) with osteoporosis who had previously taken bisphosphonates were randomized to receive open-label subcutaneous romosozumab (210 mg once monthly; n = 218) or teriparatide (20 µg once daily; n = 218) for 12 months. BMD was assessed by dual-energy X-ray absorptiometry at the proximal femur and lumbar spine (LS) at baseline and months 6 and 12. To assess the utility of P1NP, the positive predictive value of increase from baseline in P1NP of > 10 µg/L at month 1 and achievement of various thresholds of percent change from baseline in BMD at month 12 were evaluated. RESULTS Overall, 95% (191/202) of patients in the romosozumab group and 91% (183/201) in the teriparatide group demonstrated an increase in P1NP of > 10 µg/L from baseline at month 1. Among these patients, 18% and 3% of romosozumab-treated patients versus 60% and 12% of teriparatide-treated patients showed no increase from baseline (i.e., ≤ 0%) in total hip and LS BMD, respectively, at month 12. These data indicate that in patients switching from bisphosphonates to a bone-forming therapy, increases in P1NP do not help predict the hip BMD response. Although most patients treated with either teriparatide or romosozumab showed an increase in P1NP, the majority of patients on romosozumab showed an increase in hip BMD, while more than half of the patients on teriparatide did not. Teriparatide therapy did not increase total hip BMD in the majority of patients who transitioned from bisphosphonates to teriparatide. CONCLUSIONS Thus, increases in P1NP were not predictive of BMD response in the teriparatide group because in approximately 60% of the patients who were administered teriparatide, the hip BMD decreased independent of the change in P1NP levels.

Abstract
Radiographic vertebral fractures (VFxs) are the most common fractures in osteoporosis and are associated with increased morbidity, mortality, and costs. A subset of VFxs manifest clinically, usually with a sudden onset of severe back pain. Romosozumab is a monoclonal antibody that binds and inhibits sclerostin, increasing bone formation and decreasing bone resorption, leading to rapid and large increases in bone density and strength and reduction in fracture risk. The FRAME (Fracture Study in Postmenopausal Women with Osteoporosis) study of postmenopausal women with osteoporosis demonstrated a significant reduction in new VFxs with romosozumab versus placebo. Here, we report the effect of romosozumab versus placebo on clinical VFx incidence over 12 months in women reporting back pain suggestive of VFxs. FRAME enrolled 7180 postmenopausal women with osteoporosis, mean age 70.9 years (hip T‐score −2.5 to −3.5). In the first year of the study, women received monthly romosozumab 210 mg (n = 3589) or placebo (n = 3591). At regular monthly visits, women reporting back pain suggestive of a clinical VFx had a confirmatory spine X‐ray. Clinical VFx risk in the romosozumab group versus the placebo group was calculated by Cox‐proportional hazards model. Of 119 women in FRAME with back pain suggestive of a clinical VFx over 12 months, 20 were confirmed to have experienced a new/worsening VFx. Three women receiving romosozumab had a clinical VFx (<0.1% of 3589 women) versus 17 (0.5% of 3591 women) receiving placebo resulting in a reduction in clinical VFx risk of 83% in the romosozumab group versus placebo through 12 months (HR 0.17; 95% CI, 0.05 to 0.58; p = 0.001). In the three romosozumab‐treated women, clinical VFxs occurred within the first 2 months of the study with no further clinical VFxs throughout the year. Romosozumab treatment for 12 months was associated with rapid and large reductions in clinical VFx risk versus placebo. © 2019 The Authors.

Abstract
Romosozumab, a humanized monoclonal antibody that binds and inhibits sclerostin, has the dual effect of increasing bone formation and decreasing bone resorption. As previously reported in the pivotal FRActure study in postmenopausal woMen with ostEoporosis (FRAME), women with a T-score of ≤ -2.5 at the total hip or femoral neck received subcutaneous placebo or romosozumab once monthly for 12 months, followed by open-label subcutaneous denosumab every 6 months for an additional 12 months. Upon completion of the 24-month primary analysis period, eligible women entered the extension phase and received denosumab for an additional 12 months. Here, we report the final analysis results through 36 months, including efficacy assessments of new vertebral, clinical, and nonvertebral fracture; bone mineral density (BMD); and safety assessments. Of 7180 women enrolled, 5743 (80%) completed the 36-month study (2851 romosozumab-to-denosumab; 2892 placebo-to-denosumab). Through 36 months, fracture risk was reduced in subjects receiving romosozumab versus placebo for 12 months followed by 24 months of denosumab for both groups: new vertebral fracture (relative risk reduction [RRR], 66%; incidence, 1.0% versus 2.8%; p < 0.001), clinical fracture (RRR, 27%; incidence, 4.0% versus 5.5%; p = 0.004), and nonvertebral fracture (RRR, 21%; incidence, 3.9% versus 4.9%; p = 0.039). BMD continued to increase for the 2 years with denosumab treatment in both arms. The substantial difference in BMD achieved through 12 months of romosozumab treatment versus placebo was maintained through the follow-up period when both treatment arms received denosumab. Subject incidence of adverse events, including positively adjudicated serious cardiovascular adverse events, were overall balanced between groups. In conclusion, in postmenopausal women with osteoporosis, 12 months of romosozumab led to persistent fracture reduction benefit and ongoing BMD gains when followed by 24 months of denosumab. The sequence of romosozumab followed by denosumab may be a promising regimen for the treatment of osteoporosis. © 2018 American Society for Bone and Mineral Research.

Abstract
UNLABELLED Romosozumab, which binds sclerostin, rebuilds the skeletal foundation before transitioning to antiresorptive treatment. This subgroup analysis of an international, randomized, double-blind study in postmenopausal women with osteoporosis showed efficacy and safety outcomes for romosozumab followed by denosumab in Japanese women were generally consistent with those for the overall population. PURPOSE In the international, randomized, double-blind, phase 3 FRActure study, in postmenopausal woMen with ostEoporosis (FRAME; NCT01575834), romosozumab followed by denosumab significantly improved bone mineral density (BMD) and reduced fracture risk. This report evaluates Japanese women in FRAME. METHODS Postmenopausal women with osteoporosis (T-score - 3.5 to - 2.5 at total hip or femoral neck) received romosozumab 210 mg or placebo subcutaneously monthly for 12 months, then each group received denosumab 60 mg subcutaneously every 6 months for 24 months. The key endpoint for Japanese women was BMD change. Other endpoints included new vertebral, clinical, and nonvertebral fracture; the subgroup analysis did not have adequate power to demonstrate statistically significant reductions. RESULTS Of 7180 enrolled subjects, 492 (6.9%) were Japanese (247 romosozumab, 245 placebo). BMD increases from baseline were greater (P < 0.001) for romosozumab-to-denosumab than placebo-to-denosumab at the lumbar spine (36 months, 12.7%), total hip (4.2%), and femoral neck (4.1%). Fracture risk was lower through 36 months for romosozumab-to-denosumab vs placebo-to-denosumab for new vertebral (1.7% vs 4.5%; relative risk reduction (RRR) 63%, P = 0.070), clinical (3.2% vs 7.3%; RRR 53%, P = 0.072), nonvertebral (2.8% vs 6.1%; RRR 50%, P = 0.12), and all other fracture types evaluated. Rates of adverse events and positively adjudicated serious cardiovascular events were generally balanced between groups. CONCLUSIONS Efficacy and safety for romosozumab-to-denosumab were similar between Japanese women and the overall population. The sequence of romosozumab to rebuild the skeletal foundation before transitioning to antiresorptive treatment with denosumab is a promising regimen for Japanese postmenopausal women with osteoporosis at high risk of fracture.

Abstract
CONTEXT Globally, one in five men aged >50 years is predicted to experience an osteoporotic fracture. Because of the treatment gap in osteoporosis and the paucity of bone-forming agents for men, new osteoporosis treatments are needed. OBJECTIVE To evaluate the safety and efficacy of romosozumab in men with osteoporosis. DESIGN Phase III randomized BRIDGE study (placebo-controlled double-blind study evaluating the efficacy and safety of romosozumab in treating men with osteoporosis; ClinicalTrials.gov identifier, NCT02186171) for 12 months. SETTING Thirty-one centers in Europe, Latin America, Japan, and North America. PATIENTS Men aged 55 to 90 years with a baseline bone mineral density (BMD) T-score at the lumbar spine (LS), total hip (TH), or femoral neck of ≤-2.5 or ≤-1.5 with a history of a fragility nonvertebral or vertebral fracture. INTERVENTIONS The subjects were randomized 2:1 to receive romosozumab 210 mg subcutaneously monthly or placebo for 12 months. MAIN OUTCOME MEASURES The primary efficacy endpoint was percentage change from baseline in LS BMD at month 12. RESULTS In 245 subjects (163 romosozumab, 82 placebo), at month 12, the mean percentage change from baseline in the LS and TH BMD was significantly greater for the romosozumab group than for the placebo group (LS, 12.1% vs 1.2%; TH, 2.5% vs -0.5%; P < 0.001). Adverse events and serious adverse events were balanced between the two groups, with a numerical imbalance in the positively adjudicated cardiovascular serious adverse events [romosozumab, 8 (4.9%) vs placebo, 2 (2.5%)]. CONCLUSIONS Treatment with romosozumab for 12 months increased the spine and hip BMD compared with placebo and was well tolerated in men with osteoporosis.

Abstract
UNLABELLED Osteoporosis (OP) causes reduced bone strength and increases risk of fractures. Medical records from specialist clinics in Japan of postmenopausal women with OP and high risk of fracture were analysed. Majority of patients were treated for OP as recommended and were prescribed OP medications soon after high-risk OP diagnosis. PURPOSE The incidence of osteoporosis (OP) in Japan is predicted to increase significantly in coming decades. Resultant osteoporotic fractures are a significant contributor of economic and social burden among elderly osteoporosis patients. This retrospective chart review was conducted as a response to the current evidence gap in the treatment patterns for OP patients with high risk of fracture in Japan. METHODS This was a multi-centre retrospective chart review that analysed data extracted from the medical records of postmenopausal OP patients at high risk for fracture who received care at 11 specialist clinics and medical centers in Japan for at least 18 to 24 months. Main outcome was OP treatment patterns. RESULTS The study included 709 eligible patients of whom 623 (87.9%) were prescribed OP medication during the study period. The most common reason for not taking OP medication was patient unwillingness to take medication. The most common OP medications prescribed initially were minodronic acid (20.1%), alendronate (19.9%), raloxifene (14.1%), weekly teriparatide acetate (12.4%) and eldecalcitol (11.4%). Majority of patients (62.1%) were still taking their initial medication at the end of the 18-24 month follow-up. CONCLUSIONS A high percentage of patients (87.9%) in Japan received OP medications soon after their high-risk diagnosis, with bisphosphonates, selective estrogen receptor modulators and teriparatide being the predominant treatment options.

Abstract
BACKGROUND Romosozumab is a monoclonal antibody that inhibits sclerostin and rapidly increases bone mineral density (BMD) through a dual effect on bone by increasing bone formation and decreasing bone resorption, as shown in a global phase 2 study in postmenopausal women with low bone mass. Here, we report the key results of a phase 2, double-blind, placebo-controlled, dose-ranging study to assess the efficacy and safety of romosozumab in postmenopausal Japanese women with osteoporosis. METHODS Participants were postmenopausal Japanese women with osteoporosis aged 55-85years with a lumbar spine, total hip, or femoral neck dual-energy X-ray absorptiometry T-score≤-2.5. Women were randomized to receive placebo or romosozumab (70, 140, or 210mg) subcutaneously once monthly (QM) for 12months. The primary efficacy endpoint was the percentage change from baseline in lumbar spine BMD at month 12. Secondary efficacy endpoints included the percentage change from baseline in lumbar spine BMD at month 6, total hip and femoral neck BMD at months 6 and 12, and serum bone turnover markers procollagen type 1N-terminal propeptide (P1NP) and C-terminal telopeptide of type 1 collagen (CTX) at multiple visits. RESULTS This study enrolled 252 women who had a mean age of 67.7years and mean T-scores of -2.7, -1.9, and -2.3 at the lumbar spine, total hip, and femoral neck, respectively. All romosozumab doses significantly increased BMD at month 12 compared with placebo (p<0.01), with the largest mean gains from baseline observed with romosozumab 210mg QM (lumbar spine=16.9%, total hip=4.7%, and femoral neck=3.8%). All doses of romosozumab significantly increased the levels of bone-formation marker P1NP and reduced the levels of bone-resorption marker CTX by week 1 (p<0.001 vs placebo). In the 210mg QM group, P1NP levels peaked at month 1 and fell below placebo levels by month 12; CTX levels were lowest at week 1 and remained below placebo through month 12. The patient incidences of adverse events and serious adverse events were generally comparable between treatment groups. CONCLUSIONS In postmenopausal Japanese women with osteoporosis, romosozumab treatment resulted in large and significant gains in BMD from baseline and compared with placebo. Romosozumab 210mg QM showed the largest gains in BMD and was generally well tolerated. The efficacy and safety of romosozumab 210mg QM in this phase 2 study of postmenopausal women with osteoporosis were similar to those in an international phase 2 study.

Abstract
The seizure threshold 2 (SZT2) gene encodes a large, highly conserved protein that is associated with epileptogenesis. In mice, Szt2 is abundantly expressed in the central nervous system. Recently, biallelic SZT2 mutations were found in 7 patients (from 5 families) presenting with epileptic encephalopathy with dysmorphic features and/or non-syndromic intellectual disabilities. In this study, we identified by whole-exome sequencing compound heterozygous SZT2 mutations in 3 patients with early-onset epileptic encephalopathies. Six novel SZT2 mutations were found, including 3 truncating, 1 splice site and 2 missense mutations. The splice-site mutation resulted in skipping of exon 20 and was associated with a premature stop codon. All individuals presented with seizures, severe developmental delay and intellectual disabilities with high variability. Brain MRIs revealed a characteristic thick and short corpus callosum or a persistent cavum septum pellucidum in each of the 2 cases. Interestingly, in the third case, born to consanguineous parents, had unexpected compound heterozygous missense mutations. She showed microcephaly despite the other case and previous ones presenting with macrocephaly, suggesting that SZT2 mutations might affect head size.

Abstract
Papillary microcarcinoma (PMC) of the thyroid is defined as papillary thyroid carcinoma (PTC) measuring ≤1 cm. Many autopsy studies on subjects who died of non-thyroidal diseases reported latent small thyroid carcinoma in up to 5.2% of the subjects. A mass screening study for thyroid cancer in Japanese adult women detected small thyroid cancer in 3.5% of the examinees. This incidence was close to the incidence of latent thyroid cancer and more than 1000 times the prevalence of clinical thyroid cancer in Japanese women reported at that time. The question of whether it was correct to treat such PMCs surgically then arose. In 1993, according to Dr. Miyauchi's proposal, Kuma Hospital initiated an active surveillance trial for low-risk PMC as defined in the text. In 1995, Cancer Institute Hospital in Tokyo, Japan, started a similar observation trial. The accumulated data from the trials at these two institutions strongly suggest that active surveillance (i.e., observation without immediate surgery) can be the first-line management for low-risk PMC. Although our data showed that young age and pregnancy might be risk factors of disease progression, we think that these patients can also be candidates for active surveillance, because all of the patients who showed progression signs were treated successfully with a rescue surgery, and none of them died of PTC. In this review, we summarize the data regarding the active surveillance of low-risk PMC as support for physicians and institutions that are considering adopting this strategy.

Abstract
OBJECTIVE Solid variants of papillary thyroid carcinoma (SV-PTC) are rare, and there have been few reports describing the cytological findings of such variants. METHODS The cytological features of cellular specimens aspirated from 18 histologically confirmed SV-PTC cases were evaluated, retrospectively. RESULTS Solid and small papillary clusters were observed in 14 (77.8%) and 13 (72.2%) cases, respectively. The incidences of large papillary clusters (11.1%) and sheet-like arrangements (11.1%) were low. Nuclear features were consistent with conventional PTC. The background was clean, and there were no colloid materials, foamy histiocytes, multinucleated giant cells, psammoma bodies, or necrotic materials. CONCLUSIONS Solid clusters and small papillary clusters in conjunction with a clean background are diagnostic clues that indicate SV-PTC cytologically. It is thought that small papillary clusters reflect the micropapillary growth pattern seen within the lumen of middle-sized follicular structures. The presence of nuclear findings typical of conventional PTC and the absence of mitotic figures and necrotic materials are important for distinguishing SV-PTC from poorly differentiated carcinoma.

Abstract
BACKGROUND Romosozumab, a monoclonal antibody that binds sclerostin, increases bone formation and decreases bone resorption. METHODS We enrolled 7180 postmenopausal women who had a T score of -2.5 to -3.5 at the total hip or femoral neck. Patients were randomly assigned to receive subcutaneous injections of romosozumab (at a dose of 210 mg) or placebo monthly for 12 months; thereafter, patients in each group received denosumab for 12 months, at a dose of 60 mg, administered subcutaneously every 6 months. The coprimary end points were the cumulative incidences of new vertebral fractures at 12 months and 24 months. Secondary end points included clinical (a composite of nonvertebral and symptomatic vertebral) and nonvertebral fractures. RESULTS At 12 months, new vertebral fractures had occurred in 16 of 3321 patients (0.5%) in the romosozumab group, as compared with 59 of 3322 (1.8%) in the placebo group (representing a 73% lower risk with romosozumab; P<0.001). Clinical fractures had occurred in 58 of 3589 patients (1.6%) in the romosozumab group, as compared with 90 of 3591 (2.5%) in the placebo group (a 36% lower risk with romosozumab; P=0.008). Nonvertebral fractures had occurred in 56 of 3589 patients (1.6%) in the romosozumab group and in 75 of 3591 (2.1%) in the placebo group (P=0.10). At 24 months, the rates of vertebral fractures were significantly lower in the romosozumab group than in the placebo group after each group made the transition to denosumab (0.6% [21 of 3325 patients] in the romosozumab group vs. 2.5% [84 of 3327] in the placebo group, a 75% lower risk with romosozumab; P<0.001). Adverse events, including instances of hyperostosis, cardiovascular events, osteoarthritis, and cancer, appeared to be balanced between the groups. One atypical femoral fracture and two cases of osteonecrosis of the jaw were observed in the romosozumab group. CONCLUSIONS In postmenopausal women with osteoporosis, romosozumab was associated with a lower risk of vertebral fracture than placebo at 12 months and, after the transition to denosumab, at 24 months. The lower risk of clinical fracture that was seen with romosozumab was evident at 1 year. (Funded by Amgen and UCB Pharma; FRAME ClinicalTrials.gov number, NCT01575834 .).

Abstract
Teriparatide(recombinant human PTH1-34, 20 μg daily subcutaneous injection)has been approved for osteoporosis patients at high risk of fracture in many countries including Japan. Teriparatide daily injection therapy has been reported to increase BMD, improve microarchitecture of bone, and reduce the risk of new vertebral fractures and that of non-vertebral fractures. Pharmakokinetic(PK)study after a single Teriparatide injection of the daily dose in healthy Japanese postmenopausal women(n=18)revealed very rapid achievement of peak blood level(median of tmax=0.25 hr)followed by fast disappearance from the blood(mean t1/2=0.708 hr, n=17). Consistent with these PK characteristics, a rapid increase in bone formation marker and later increase in bone resorption marker has previously been observed, which was described as a bone anabolic window. More recently, once weekly subcutaneous injection of teriparatide acetate(56.5 μg)has been reported to reduce the risk of new vertebral fractures compared with placebo and has been approved in Japan. PK study after injection of the higher weekly dose in healthy Japanese postmenopausal women(n=10)revealed a relatively slow achievement of the peak blood level(mean tmax=0.875 hr)compared to daily injections, followed by relatively slow disappearance from the blood(mean t1/2=1.295 hr). Consistent with these PK characteristics, an initial(<24 hr)transient decrease of bone formation markers(serum osteocalcin and P1NP)and transient increase of bone resorption markers(serum NTX and urinary CTX)were observed. However, afterword, the bone formation and resorption markers were increased and decreased, respectively, for longer than 1 week from the baseline levels. The relationship of pharmacokinetics, changes of bone turnover markers and BMD/fractures efficacy during daily versus weekly teriparatide treatment needs to be clarified.

Abstract
Transforming growth factor-beta1 is an important local regulator of bone metabolism, acting downstream of estrogen and cooperatively with vitamin D. The possible association of a C 509-->T polymorphism in the promoter region of the transforming growth factor-beta1 gene, alone or in combination with a T869-->C (Leu10-->Pro) polymorphism, with bone mineral density and genetic susceptibility to osteoporosis was investigated in 625 postmenopausal Japanese women. The frequencies of the CC, CT, and TT genotypes of the C-509-->T polymorphism in the study population were 24%, 49%, and 27%, respectively. A significant association of C-509-->T genotype with bone mineral density was detected: lumbar spine (L2-L4) and total body bone mineral density values were 7% and 5% lower, respectively, in individuals with the TT genotype than in those with the CT or CC genotype. The serum concentration of transforming growth factor-beta1 did not vary with C-509-->T genotype. Multivariable logistic regression analysis, with adjustment for age, height, body weight, time since menopause, smoking status, body fat mass, and lean mass, revealed a significantly higher frequency of the TT genotype of the C-509-->T polymorphism in 286 individuals with osteoporosis than in 170 normal controls. Analysis of combined C-509-->T and T869-->C genotypes showed that L2-L4 bone mineral density decreases and the prevalence of osteoporosis increases with the number of T alleles. These results suggest that the C-509-->T polymorphism, alone or in combination with the T869-->C polymorphism, of the transforming growth factor-beta1 gene is a genetic determinant of bone mass, and that the number of T alleles in the combined genotype is a risk factor for the genetic susceptibility to osteoporosis in postmenopausal Japanese women.

Abstract
BACKGROUND A diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC) is a rare variant and reports describing the cytological findings are few. PATIENTS AND METHODS We studied 24 cytological samples from thyroid fine needle aspirates of 20 patients with DSV-PTC. The specimens were taken from 14 non-nodular lesions and 10 nodules. RESULTS All aspirates taken from both non-nodular lesions and nodules had sufficient cellularity. The carcinoma cells frequently (70-100%) appeared as solid cell balls and hollow balls, and showed a hobnail pattern, squamous differentiation, septate cytoplasmic vacuoles and large unilocular vacuoles. Most of the carcinoma cells seem to be taken from the lumen of dilated lymph vessels. Ground glass nuclear chromatin, intranuclear cytoplasmic inclusions and grooved nuclei were infrequent (50% or less). In the background, a large number of lymphocytes and abundant psammoma bodies were almost always seen. CONCLUSIONS Cytological findings of DSV-PTC are as follows: (1) solid cell balls and/or hollow balls containing lymphocytes; (2) hobnail cells; (3) septate cytoplasmic vacuoles; (4) large unilocular vacuoles; (5) squamous differentiation; (6) abundant psammoma bodies; (7) lymphocytic background; and (8) the absence or relative lack of characteristic nuclear features of papillary carcinoma. When DSV-PTC is suspected by ultrasound examination, the aspiration cytology from a non-nodular area of the thyroid can led us to the diagnosis of the variant.

Abstract
This large-scale postmarketing surveillance of raloxifene (60 mg/day) was conducted to assess the safety and effectiveness of raloxifene for long-term use in postmenopausal Japanese women with osteoporosis. The baseline examination included 6,967 women (mean age, 70.4 years). Participants completed observation after 6, 12, 24, and 36 months of therapy. Adverse drug reactions (ADR) were reported in 776 participants (11.14 %), with a total of 87 serious ADR cases occurring in 76 participants (1.09 %). The most frequently reported ADRs were edema peripheral (45/6,967, 0.65 %) and venous thromboembolism (11/6,967, 0.16 %). Of the 6,967 participants, 2,784 were included in the effectiveness analysis. Lumbar spine bone mineral density (BMD) increased significantly (p < 0.001, paired t test) compared with baseline at 6, 12, 24, and 36 months (2.51 %, 2.85 %, 4.76 %, and 3.51 %, respectively). Significant decreases in serum and urinary cross-linked amino-terminal telopeptide of type I collagen (NTX) and urinary deoxypyridinoline levels from baseline were observed at 3 months, followed by a significant decrease of serum bone alkaline phosphatase at 6 months [p < 0.001 for all comparisons except serum NTX (p = 0.011), Wilcoxon signed-rank test]. Early reductions in the biochemical markers of bone turnover (BTM) observed at 3 months with raloxifene treatment correlated negatively with subsequent increases in lumbar spine BMD at 1 year (r = -0.347, p = 0.008). The incidence of any new clinical fractures within 3 years was 1.18 % (82/6,967 participants). In summary, no new signals in safety were observed in the daily use of raloxifene. Moreover, the effectiveness profile of raloxifene was confirmed in practical use by this large-scale, long-term, postmarketing surveillance.

Abstract
OBJECTIVE To assess changes in quality of life (QOL) and pain in raloxifene-treated Japanese women with postmenopausal osteoporosis. RESEARCH DESIGN AND METHODS This prospective, postmarketing observational study was conducted at 60 Japanese hospitals from September 2007 to February 2009 and included Japanese women with postmenopausal osteoporosis who were new to standard treatment with raloxifene (60 mg/day). Primary outcome measures (QOL and pain) were assessed using the Short Form-8 (SF-8), European Quality of Life Instrument (EQ-5D), osteoporosis-specific Japanese Osteoporosis Quality of Life Questionnaire (JOQOL), a visual analogue scale (VAS-pain), and a pain frequency survey. Assessments were performed at baseline and 8 (except JOQOL) and 24 weeks after first administration of raloxifene. Adverse drug reactions were recorded. Japan Pharmaceutical Information Center registration number: JapicCTI-070465. RESULTS A total of 506 participants, mean (±standard deviation [SD]) age = 70.7 ± 8.7 years, completed ≥1 follow-up assessment and were included in the analyses. All QOL scores increased from baseline during follow-up. All SF-8 domain scores increased significantly from baseline after 8 and 24 weeks (P < 0.001). Mean (±SD) EQ-5D scores increased significantly from baseline (0.70 ± 0.17) by 0.05 ± 0.15 after 8 weeks and 0.07 ± 0.17 after 24 weeks (P < 0.001). The mean (±SD) total JOQOL score increased significantly from baseline (66.8 ± 16.5) by 3.8 ± 11.3 after 24 weeks (P < 0.001). The percentage of participants with a ≥20 mm reduction in VAS-pain was 32.6% (120/368) and 39.5% (115/291) after 8 and 24 weeks, respectively. The frequency of pain reported by participants decreased after 8 and 24 weeks. Forty adverse drug reactions were reported by 34 participants. LIMITATIONS Limitations include the lack of a control group, the possibility of the changes being due to the natural disease course, and potential selection bias. CONCLUSIONS Our findings suggest that standard treatment with raloxifene improves QOL and relieves pain in Japanese women with postmenopausal osteoporosis in a real-world clinical setting.

Abstract
BACKGROUND Integrin αIIbβ3 plays key roles in platelet aggregation and subsequent thrombus formation. Hydrogen peroxide-inducible clone-5 (Hic-5), a member of the paxillin family, serves as a focal adhesion adaptor protein associated with αIIbβ3 at its cytoplasmic strand. OBJECTIVES Hic-5 function in αIIbβ3 activation and subsequent platelet aggregation remains unknown. To address this question, platelets from Hic-5(-/-) mice were analyzed. METHODS AND RESULTS Hic-5(-/-) mice displayed a significant hemostatic defect and resistance to thromboembolism, which were explained in part by weaker thrombin-induced aggregation in Hic-5(-/-) platelets. Mechanistically, Hic-5(-/-) platelets showed limited activation of αIIbβ3 upon thrombin treatment. Morphological alteration in Hic-5(-/-) platelets after thrombin stimulation on fibrinogen plates was also limited. As a direct consequence, the quantity of actin co-immunoprecipitating with the activated αIIbβ3 was smaller in Hic-5(-/-) platelets than in wild-type platelets. CONCLUSION We identified Hic-5 as a novel and specific regulatory factor for thrombin-induced αIIbβ3 activation and subsequent platelet aggregation in mice.

Abstract
Teriparatide (recombinant human PTH1-34 daily subcutaneous injection) has been approved for osteoporosis at high risk of fracture in many countries including Japan. Teriparatide daily injection therapy has been reported to increase BMD, improve microarchitecture of bone, and reduce the risk of new vertebral fractures and that of non-vertebral fractures. The observed rapid increase in bone formation marker and later increase in bone resorption marker has been described as a bone anabolic window. The accumulated information using data from global clinical trials further tested in the Phase 3 trial of Japanese patients suggests that P1NP monitoring may be a useful aid in the management of patients with osteoporosis during teriparatide daily injection treatment. Recently once weekly subcutaneous injection of teriparatide has been approved in Japan. Weekly teriparatide injection treatment has been reported to reduce the risk of new vertebral fractures compared with placebo. Regarding bone turnover markers, serum osteocalcin increased and urinary NTX decreased during the weekly teriparatide treatment.

Abstract
Somatic mutations of the TSH receptor (TSHR) gene are the main cause of autonomously functioning thyroid nodules. Except for mutations in ectodomain residue S281, all of the numerous reported activating mutations are in the TSHR membrane-spanning region. Here, we describe a patient with a toxic adenoma with a novel heterozygous somatic mutation caused by deletion of ectodomain residue Asp403 (Del-D403). Subsequent in vitro functional studies of the Del-D403 TSHR mutation demonstrated greatly increased ligand-independent constitutive activity, 8-fold above that of the wild-type TSHR. TSH stimulation had little further effect, indicating that the mutation produced near maximal activation of the receptor. In summary, we report only the second TSHR ectodomain activating mutation (and the first ectodomain deletion mutation) responsible for development of a thyroid toxic adenoma. Because Del-D403 causes near maximal activation, our finding provides novel insight into TSHR structure and function; residue D403 is more likely to be involved in the ligand-mediated activating pathway than in the ectodomain inverse agonist property.

Abstract
Oncogenic osteomalacia (OOM), or tumor-induced osteomalacia, is a rare disease characterized by renal phosphate wasting and osteomalacia. It arises due to the secretion of fibroblast growth factor 23 (FGF-23) from causative tumors. Matrix extracellular phosphoglycoprotein (MEPE) is predominantly expressed in odontoblasts, osteoblasts, and osteocytes. Although the presence of MEPE mRNA has been reported in some OOM tumors, little is known about the prevalence of MEPE expression in OOM tumors. In this study, the expression of MEPE and FGF-23 in OOM tumors was investigated at the transcriptional and translational levels. Eleven causative OOM tumors were analyzed by quantitative real-time reverse transcription-polymerase chain reaction and immunohistochemistry for MEPE and FGF-23 expression. Hemangiopericytomas and giant cell tumors, pathological diagnoses that are common in cases of OOM, were obtained from non-osteomalacic patients and analyzed as controls. The gene expression level of FGF23 and MEPE in OOM tumors was 10(4)- and 10(5)-times higher, respectively, than in non-OOM tumors. Immunohistochemical staining revealed that FGF-23 protein was expressed in all OOM tumors, and MEPE was expressed in 10 out of 11 OOM tumors. Thus, MEPE expression was common in OOM tumors, similar to FGF-23. These results indicate that, in addition to the hypophosphatemic effects of FGF-23, MEPE or the MEPE-derived acidic serine aspartate-rich MEPE-associated motif peptide may contribute to decreased bone mineralization in OOM patients.

Abstract
Back and knee pain is a widespread health problem and a serious threat to the quality of life (QOL) in middle-aged and older adults, as it frequently accompanies osteoporosis and osteoarthritis. In order to compare the effects of elcatonin and risedronate on such pain, 20 units of elcatonin was intramuscularly injected to 18 patients, and 5 mg of risedronate was orally administered daily to 20 others with similar backgrounds. Exercise-induced pain was analyzed by measuring the fall of skin impedance by electroalgometry (EAM), and subjective pain was recorded by a visual rating system (VRS) on a scale of 0 (no pain) to 100 (unbearable pain). In patients treated with elcatonin, the mean EAM-estimated pain was significantly reduced after 4, 5 and 6 months of treatment, and the VRS score after 3, 5 and 6 months, indicating a significant analgesic effect. In the risedronate group, however, improvement was less remarkable. Two-way analysis of variance using pain as a dependent variable and treatment group and time as independent variables revealed a significantly greater effect of elcatonin over risedronate on both the EAM and VRS scores, and the influence of treatment time on pain was indistinguishable between the two treatment groups. Effect of exercise load on pain was less on knee load than knee and spine load and spine load, but indistinguishable between the two groups. Changes in QOL were evaluated by the SF-36 system. Norm-based scoring showed significant improvements in 3 of 4 categories for elcatonin and in 2 of 4 for risedronate, suggesting comparable effects on the physical aspects of QOL, whereas responses to emotionally and socially directed questions indicated significant improvements in all 4 categories for risedronate, but none for elcatonin, suggesting a more physical than emotional component in elcatonin effects compared to risedronate.

Abstract
INTRODUCTION Vertebral fractures are the most common osteoporotic fracture and the prevalence of vertebral fracture is commonly assessed in clinical practice in Japan. The objective of this study was to evaluate potential risk factors for osteoporotic fractures, including morphometric spine fracture status and the WHO risk factors for predicting 4-year fracture risk. METHODS A population-based community cohort, the Adult Health Study, consisting of 2613 men and women with mean age of 65 enrolled in Hiroshima was followed prospectively for 4 years. The prevalence and incidence of spine fractures were identified from lateral and posterior-anterior spine radiographs using a semiquantitative method. Information on incident nonvertebral fragility fractures (hip, proximal humeral, and forearm) was collected at interviews by trained nurses and physicians during biennial health examinations. RESULTS A model, including spine fracture status in addition to the WHO risk factors, appeared to provide greater prognostic information regarding future fracture risk (gradient of risk/standard deviation: GR/SD=2.73) than a model with the WHO risk factors alone (GR/SD=2.54). In univariate analyses, age, bone mineral density (BMD), prior clinical fracture, and spine fracture status had the highest gradient of risk. The presence of multiple prevalent spine or non-spine fractures significantly increased fracture risk, but, their contributions to the gradient of risk were similar to those when fracture status was categorized as a binary variable. A model considering those four risk factors yielded GR/SD=2.67, indicating that it could capture most of the predictive information provided by the model with spine fracture status plus the WHO risk factors. CONCLUSION The use of age, BMD, prior clinical fracture and spine fracture predicted future fracture risk with greater simplicity and higher prognostic accuracy than consideration of the risk factors included in the WHO tool.

Abstract
Biochemical markers of bone turnover may be useful aids for managing patients with osteoporosis. A 12-month, phase 3, multicenter trial of Japanese patients at high risk of fracture was conducted to assess the effects of teriparatide 20 μg/day on BMD, serum markers of bone turnover, and safety. Two-hundred and seven subjects (93% female; median age 70 years) were randomized in double-blind fashion 2:1 to teriparatide versus placebo. Bone turnover markers including procollagen type I N-terminal propeptide (PINP), bone-specific alkaline phosphatase (bone ALP) and type I collagen cross-linked C-telopeptide (CTX) were collected at baseline, 1, 3, 6, and 12 months. Lumbar spine, femoral neck, and total hip BMD were measured at baseline, 3, 6, and 12 months. Increases in PINP at 1 month correlated best with increases in lumbar spine BMD at 12 months (r=0.76; P<0.01). The proportions of patients with an increase from baseline in PINP >10 μg/L at 1, 3, and 6 months were 3%, 0%, and 2% in the placebo, and 93%, 87%, and 83% in the teriparatide group. The proportions of patients with an increase in PINP >10 μg/L at either 1 or 3 months were 3% in the placebo and 95% in the teriparatide group (P<0.001). The proportions of patients with a significant increase in lumbar spine BMD (increase from baseline ≥3%) at 12 months were 20% in the placebo and 94% in the teriparatide group. The proportions of patients with an increase in PINP >10 μg/L at 1 or 3 months and an increase in lumbar spine BMD ≥3% at 12 months was 0% of placebo group patients and 92% of teriparatide group patients (P<0.001). These data confirm a strong relationship between early change in PINP and later change in lumbar spine BMD during teriparatide therapy. Also, these results suggest that monitoring with PINP and lumbar spine BMD successfully identifies positive responses in most patients taking teriparatide and negative responses in most patients not taking teriparatide. PINP monitoring may be a useful aid in the management of patients with osteoporosis during teriparatide treatment.

Abstract
This multicenter study assessed the safety and efficacy of teriparatide 20 microg/day in Japanese men and women with osteoporosis at high risk of fracture during a 12-month, randomized, double-blind, placebo-controlled treatment period followed by second and third treatment periods (to 18 and 24 months, respectively,) in which all subjects received open-label teriparatide. Subjects (93% female; median age 70 years) were randomized 2:1 to teriparatide versus placebo (randomized at baseline, teriparatide n=137, placebo-teriparatide n=70; entering the second period, teriparatide n=119, placebo-teriparatide n=59; entering the third period, teriparatide n=102, placebo-teriparatide n=50). For subjects with measurements at 12 months, teriparatide significantly increased bone mineral density (BMD) at the lumbar spine L2-L4 (mean percent change+/-SD, teriparatide 10.04+/-5.23% versus placebo-teriparatide 0.19+/-4.33%), the femoral neck (teriparatide 2.01+/-4.63% versus placebo-teriparatide 0.44+/-3.97%), and the total hip (teriparatide 2.72+/-4.04% versus placebo-teriparatide -0.26+/-3.42%). In the placebo-teriparatide group at 24 months (12-month teriparatide dosing) BMD increased by 9.11+/-5.14% at the lumbar spine, 2.19+/-4.81% at the femoral neck and 2.46+/-3.54% at the total hip. In the teriparatide group at 18 and 24 months, BMD increased from baseline at the lumbar spine by 11.93+/-5.79% and 13.42+/-6.12%, respectively; at the femoral neck by 2.68+/-4.45% and 3.26+/-4.25%, respectively; and at the total hip by 3.02+/-3.79% and 3.67+/-3.98%, respectively. Serum procollagen I N-terminal pro-peptide (PINP) increased rapidly with teriparatide treatment (P<0.001 versus placebo at 1 month) and changed from baseline in the teriparatide and placebo-teriparatide groups at 12 months by a median of 78.95% and -17.23%, respectively, (P<0.001) and at 24 months by 49.24% and 76.12%, respectively. The incidence of treatment-emergent adverse events (TEAEs), serious TEAEs, and discontinuations due to TEAEs were comparable in the teriparatide and placebo-teriparatide groups. These data show that teriparatide 20 microg/day was well tolerated and stimulated bone formation in Japanese subjects with osteoporosis at high risk of fracture during 18 and 24 months of treatment.

Abstract
Oncogenic osteomalacia (OOM) is a rare disease characterized by renal phosphate wasting and osteomalacia and is caused by the secretion of fibroblast growth factor 23 (FGF-23) from causative tumors. Scintigraphy with octreotide, which binds to somatostatin receptors (SSTRs), is a useful way to locate causative tumors in OOM patients. However, the therapeutic effects of octreotide acetate are still controversial. Two OOM patients were administered octreotide acetate intramuscularly. Ten causative OOM tumors, including two resected from the patients participating in the octreotide administration study, were examined for expression of genes encoding SSTRs by quantitative real-time RT-PCR and immunohistochemistry. Octreotide therapy did not improve hypophosphatemia in either case, despite temporal decreases in FGF-23 levels in one patient. The mean expression levels of SSTR1, SSTR3, and SSTR5 were similar in the OOM and non-OOM tumors. Expression of SSTR2 was significantly higher in the OOM tumors than in the non-OOM tumors. Immunohistochemical examinations revealed the presence of SSTR2A, SSTR2B, and SSTR5 in both the OOM and non-OOM tumors. The expression of SSTR genes in OOM tumors contributes to positive imaging using octreotide scintigraphy. However, the levels of SSTRs seem to be insufficient for the octreotide therapy to improve hypophosphatemia. Further studies are needed to clarify the mechanisms by which FGF-23 secretion from OOM tumors is suppressed by octreotide acetate.

Abstract
BACKGROUND Homozygous mutations in fibroblast growth factor (FGF23) have recently been described as the genetic cause of one form of hyperphosphatemic tumoral calcinosis (HFTC). However, it remained unclear to date how these mutations lead to loss of biologically active FGF23 in the circulation. METHODS We here report a novel homozygous mutation, c.385T>C in FGF23 exon 2, which changes codon 129 from serine to proline (S129P) in a previously described individual affected by HFTC. The S129P mutation as well as two known FGF23 mutations, S71G and S129F, were introduced into an expression vector encoding wild-type (wt) human (h) FGF23 to yield [P129]hFGF23, [F129]hFGF23, and [G71]hFGF23; whole lysates, glycoprotein fractions, and conditioned media from HEK293 and COS-7 cells expressing these constructs were subjected to Western blot analysis using affinity-purified goat anti-hFGF23(51-69) and anti-hFGF23(206-222) antibodies. RESULTS We detected 25- and 32-kDa protein species in total lysates of HEK293 cells expressing wt-hFGF23. The 32-kDa band, representing O-glycosylated hFGF23, was not detectable in the glycoprotein fraction of lysates from HEK293 cells expressing [P129]hFGF23, and in comparison with wt-FGF23 only small amounts of [P129]hFGF23 were secreted into the medium. Similar results were obtained for cells expressing [G71]hFGF23 and [F129]hFGF23. CONCLUSION Our data for the first time directly show that FGF23 mutations associated with HFTC impair O-glycosylation in vitro resulting in poor secretion of the mutant hormone thereby explaining the characteristic hyperphosphatemic phenotype of homozygous carriers in vivo.

Abstract
Analgesic effects of etidronate, alendronate and risedronate were compared in patients with osteoporosis and/or osteoarthritis by measuring the fall of skin impedance along with conventional subjective pain-estimation by visual rating scale (VRS). One hundred ninety-nine postmenopausal women consulting the Osteoporosis and Osteoarthritis Clinic of Katsuragi Hospital complaining of back and/or knee pain were randomly divided into four groups; Group A (49 subjects) given 5 mg/day alendronate, Group E (50 subjects) 200 mg/day etidronate, Group R (50 subjects) 2.5 mg/day risedronate and Group P no bisphosphonate. None of the four groups showed significant deviation from others as to age and parameters of bone metabolism. Proportions of subjects with osteoporosis was 18-40%. Those with osteoarthritis of the spine and knee, higher than Grade II according to the Nathan and Lawrence-Kellgren scale, respectively, was 45 and 61%, respectively, without a significant difference among the four groups. Significant positive correlation was found between the fall of skin impedance and pain expressed in VRS. Attenuation of exercise-induced fall of skin impedance and also subjective pain expressed in VRS was greatest in Group E with a highly significant difference from Groups A (P = 0.0002 and P < 0.0001), R (P < 0.0001 and P = 0.0014) and P (P < 0.0001 and P < 0.0001). Neither A nor R showed significant difference from P as to the fall of skin impedance. Among the three bisphosphonates tested, etidronate appeared to be outstanding in analgesic effects.

Abstract
OBJECTIVE To gain an insight into risk factors for hypothyroidism after subacute thyroiditis (SAT), we examined the correlation between initial laboratory and ultrasonographic findings and sequential thyroid dysfunction among treatment modalities. PATIENTS We reviewed retrospectively the medical records of 252 patients (26 men and 226 women) with SAT who consecutively visited our thyroid clinic at Kuma Hospital for at least 6 months from 1996 through 2004. RESULTS Throughout the course, 135 patients (53.6%) developed transient or permanent hypothyroidism. Levels of TSH were most often elevated (greater than 5 IU/ml) 2 months after SAT onset regardless of treatment, and 97.0% of patients who showed transient or permanent hypothyroidism clustered within 6 months from onset. During follow-up, patients treated with prednisone (PSL) were more likely to have normal thyroid function than patients not treated or those receiving anti-inflammatory drug therapy. In patients who developed hypothyroidism with PSL treatment or without treatment, the rates of bilateral hypoechogenic areas (HEA) were 6-fold higher than those of unilateral HEA. Moreover, permanent hypothyroidism occurred in 5.9% of patients, and all patients with permanent hypothyroidism presented initially with bilateral HEA and had consequently small thyroid size with or without abnormal autoimmunity. CONCLUSIONS The rates of thyroid dysfunction after SAT were significantly lower in patients receiving PSL. Extent of HEA in the thyroid, but not laboratory findings, may be a possible marker for developing thyroid dysfunction after SAT.

Abstract
We evaluated the effect of the bisphosphonate, risedronate, on pain and cartilage metabolism in 33 patients with osteoarthritis of the knee, randomized into two groups. Group RC was treated with risedronate (2.5 mg/day) and calcium (900 mg/day); group C received calcium (900 mg/day) alone. Pain on exercise was estimated using a subjective visual rating scale (VRS) and an electroalgometric method of measuring decrease in skin impedance, previously shown to be indicative of pain. We measured urinary excretion of cartilage-specific collagen type II fragments as a marker of cartilage degradation. Multiple regression analysis revealed that pain alleviation as measured by skin impedance, but not VRS, was associated with a decrease in collagen fragment excretion. This suggests that, for pain evaluation, reduction in skin impedance may have a greater physiological basis compared with VRS-based evaluation. We consider that the chondroprotective and analgesic effects of risedronate may be related.

Abstract
Tensin3 is a member of tensin family which is localized in focal adhesion. In our previous study, a high level of tensin3 mRNA expression was observed in the thyroid but not in other tissues, thus, tensin3 gene was regarded as a novel thyroid-specific gene. The high expression level of tensin3 mRNA in normal thyroid tissue suggests some fundamental roles in thyroid functions. In fact, the expression level of tensin3 mRNA was low in most thyroid carcinomas and non-functioning thyroid follicular adenomas which do not produce thyroid hormone. In the present study, we measured the expression levels of tensin3 mRNA in twelve functional adenomas and compared the results with those in normal thyroid tissues, adenomatous goiters and non-functioning thyroid follicular adenomas. Tensin3 mRNA was expressed abundantly in all twelve functional adenomas at almost the same level as in normal thyroid tissues and adenomatous goiters, while its expression was significantly lower in non-functioning follicular adenomas. Considering these facts, an abundant expression of tensin3 mRNA is observed in tissues that produce thyroid hormone, which suggests some fundamental roles in basic thyroid functions.

Abstract
The dose-response efficacy and safety with three doses of teriparatide and placebo was assessed, using once-daily subcutaneous injections for 24 weeks, in Japanese postmenopausal women with osteoporosis at high risk of fracture for reasons of preexisting fracture(s), advanced age, and/or low bone mineral density (BMD). In this multicenter, randomized, placebo-controlled study, 159 subjects were randomized and 154 subjects were included for analysis. Teriparatide (10-microg, 20-microg, and 40-microg doses) showed a statistically significant increase with increasing treatment dose as assessed by the percent change of lumbar spine BMD from baseline to endpoint using Williams' test when compared with placebo (P < 0.001). The mean (+/-SD) percent change in lumbar spine, femoral neck, and total hip BMD with the 20-microg dose from baseline to endpoint was 6.40% +/- 4.76%, 1.83% +/- 7.13%, and 1.91% +/- 3.60%, respectively. Rapid and sustained increases in bone formation markers [type I procollagen N-terminal propeptide (PINP), type I procollagen C-terminal propeptide (PICP), and bone-specific alkaline phosphatase (BAP)], followed by late increases in a bone resorption marker [type I collagen cross-linked C-telopeptide (CTX)], were observed for the teriparatide treatment groups (20-microg, 40-microg), suggesting a persistent, positive, balanced anabolic effect of teriparatide. Optimal adherence was achieved by this daily self-injection treatment. Regarding safety, most of the adverse events were mild to moderate in severity. No study drug-or study procedure-related serious adverse events were reported during the treatment period. These results observed in Japanese patients may support the observation that teriparatide stimulates bone formation in patients with osteoporosis at a high risk of fracture.

Abstract
Frequency of a BRAFV600E mutation in anaplastic thyroid carcinoma, which is thought to be derived mainly from papillary carcinoma by multi-step carcinogenesis, is much lower than that in papillary carcinomas. To clarify this phenomenon, we analysed BRAFV600E mutation in 20 cases of anaplastic carcinoma and 13 accompanying differentiated carcinomas. Among twenty cases of anaplastic carcinomas, nine and four accompanied papillary and follicular carcinomas, respectively. BRAFV600E mutation was found in four (20%) cases. BRAFV600E mutation was found in three of nine (33.3%), none of four and one of seven (14.3%) anaplastic carcinomas with papillary carcinoma, follicular carcinoma and without differentiated components, respectively. All three papillary carcinomas accompanied by anaplastic carcinoma with a BRAFV600E mutation were also shown to have a BRAFV600E mutation. In summary, BRAFV600E mutation was occasionally observed in anaplastic carcinomas with papillary carcinoma, and the low frequency of BRAFV600E mutation in anaplastic carcinoma was thought to be due to the low frequency of anaplastic carcinomas with papillary carcinoma. These findings raise a question about the classical model of anaplastic transformation and suggest some roles of thyroid cancer stem cells in the generation of anaplastic carcinoma.

Abstract
AIMS To review differences in biological aggressiveness, clinical behaviors or selected surgical treatments between the PMC and the slightly larger PTC of 1.0<T<or=2.0 cm. METHODS Two hundred and twenty-seven cases of papillary thyroid carcinoma not larger than 2.0 cm, diagnosed and treated at the Kuma Hospital, Kobe, Japan, with a 10-year follow-up from 1992 to 2003, were reviewed. RESULTS The small PTCs demonstrated excellent outcomes, and persistent/recurrent disease was identified in only nine patients (4%). None of the patients died of the disease. A multivariate analysis revealed that massive extrathyroidal extension at presentation was the only independent prognostic factor for locoregional recurrence. Subdivision into PMCs and slightly larger tumors (1<T<or=2 cm) did not affect the excellent outcomes, but the patients in the latter subgroup received more lymph node surgery and displayed more aggressive clinico-histological features such as higher rates of extrathyroidal extension, lymph node metastasis, loss of polarity, invasive growth pattern and loss of cohesiveness. CONCLUSIONS Small PTC not larger than 2.0 cm could be considered as favorable a prognosis as PMC.
