Abstract
BACKGROUND A vancomycin-intermediate Staphylococcus aureus (VISA) (vancomycin minimum inhibitory concentration: 4mg/L) outbreak occurred in an advanced emergency medical service centre [hereafter referred to as the intensive care unit (ICU)] between 2013 and 2014. AIM Our objective was to evaluate the infection control measures that were successful. METHODS Seventeen VISA strains were isolated from the sputum of 15 inpatients and the skin of two inpatients. Fourteen VISA strains were recognized as colonization. However, three VISA strains were isolated from the sputum of three inpatients with pneumonia. Environmental cultures were performed and VISA strains were detected in five of 65 sites. Pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST) was performed on 21 VISA strains. FINDINGS Molecular typing including PFGE and MLST showed that the patterns of 19 VISA strains were identical and those of the other two VISA strains were possibly related. This meant that a horizontal transmission of VISA strains had occurred in the ICU. In August 2013, the infection control team began interventions. However, new inpatients with VISA strains continued to appear. Therefore, in October 2013, the ICU was partially closed in order to try to prevent further horizontal transmission, and existing inpatients with the VISA strain were isolated. Although new cases quickly dissipated after the partial closure, it took approximately five months to eradicate the VISA outbreak. CONCLUSION Our data suggest that despite the employment of various other infection control measures, partial closure of the ICU was essential in terminating this VISA outbreak.

Abstract
INTRODUCTION A multicenter retrospective survey of patients poisoned by herbicides containing glyphosate salts in Japan was conducted to identify differences in symptoms and outcome of poisoning. METHODS Participants were patients who were transported to emergency facilities between October 2006 and March 2014 after consuming herbicides containing glyphosate potassium salt (GlyK(+)) (the K-group) or other glyphosate salts (the O-group). Questionnaires were mailed to 38 emergency facilities that agreed to participate in the study. RESULTS Serum potassium levels upon arrival were significantly higher (p < 0.01), and abnormal electrocardiogram findings were significantly more common (p < 0.01) in the K-group (n = 55) than in the O-group (n = 62). Conversely, acute lung injury (ALI) including acute respiratory distress syndrome (ARDS) (p = 0.05) and liver injury (LI) (p < 0.01) were significantly more common during hospitalization in the O-group, although no significant differences in the duration of hospital stay (p = 0.92) or outcomes (p = 0.95) were observed between the two groups. DISCUSSION AND CONCLUSION The ingestion of products containing glyphosate isopropylamine or ammonium salts, and polyoxyethyleneamine (POEA) as a surfactant, can cause severe organ injury. Physicians should note that the ingestion of products containing glyphosate potassium salt and surfactants other than POEA can cause hyperkalemia, potentially leading to fatal arrhythmias or cardiac arrest.

Abstract
BACKGROUND Some patients with multiple system atrophy (MSA) require surgical interventions such as tracheostomy and aspiration prevention. Few studies have investigated the postoperative clinical course of MSA patients. The aim of this study was to determine a management strategy for dysphagia and respiratory disorder in MSA. METHODS From 2001 to 2014, 18 MSA patients (13 males and 5 females, 52-76 years) underwent tracheostomy (TR, n = 11) or laryngeal closure (LC, n = 12). Five patients underwent LC following TR. Vocal fold impairment, the degree of dysphagia and pre/post-operative oral ingestion, and postoperative survival time were evaluated retrospectively. Swallowing function was assessed using the penetration aspiration scale (PAS). RESULTS TR was performed due to respiratory disorder in seven patients and due to dysphagia in four patients. PAS scores ranged 1-8 in TR patients and 7-8 in LC patients. Seven of 11 patients who underwent TR displayed worsened PAS scores, and no patients displayed improved PAS scores following TR. All patients who underwent LC regained complete or partial oral intake after surgery. There were no significant differences in postoperative survival time between the two groups. CONCLUSIONS Considering the impacts of TR and LC on survival time, postoperative feeding and swallowing, LC is a good option for treating MSA patients with dysphagia.

Abstract
The large yellow croaker (Larimichthys crocea) is one of the largest marine net-cage cultured species in the oceans around China. In the present study, we isolated and characterized 13 polymorphic microsatellite markers from genomic libraries of L. crocea. Loci were screened for 10 wild specimens from 2 sites in southeast of China. All loci were polymorphic. The number of alleles per locus ranged from 2 to 21. The expected heterozygosity ranged from 0.233 to 0.838 and observed heterozygosity ranged from 0.527 to 0.935. Eleven loci were highly informative (polymorphic information content >0.5). Significant deviation from Hardy-Weinberg equilibrium was observed at 3 loci after Bonferroni's correction. The microsatellite loci may be valuable tools for studying the genetic diversity and genetic structure for conservation planning of the fish.

Abstract
IMPORTANCE Neurologically intact survival after out-of-hospital cardiac arrest (OHCA) has been increasing in Japan. However, associations between increased prehospital care, including bystander interventions and increases in survival, have not been well estimated. OBJECTIVE To estimate the associations between bystander interventions and changes in neurologically intact survival among patients with OHCA in Japan. DESIGN, SETTING, AND PARTICIPANTS Retrospective descriptive study using data from Japan's nationwide OHCA registry, which started in January 2005. The registry includes all patients with OHCA transported to the hospital by emergency medical services (EMS) and recorded patients' characteristics, prehospital interventions, and outcomes. Participants were 167,912 patients with bystander-witnessed OHCA of presumed cardiac origin in the registry between January 2005 and December 2012. EXPOSURES Prehospital interventions by bystander, including defibrillation using public-access automated external defibrillators and chest compression. MAIN OUTCOMES AND MEASURES Neurologically intact survival was defined as Glasgow-Pittsburgh cerebral performance category score 1 or 2 and overall performance category scores 1 or 2 at 1 month or at discharge. The association between the interventions and neurologically intact survival was evaluated. RESULTS From 2005 to 2012, the number of bystander-witnessed OHCAs of presumed cardiac origin increased from 17,882 (14.0 per 100,000 persons [95% CI, 13.8-14.2]) to 23,797 (18.7 per 100,000 persons [95% CI, 18.4-18.9]), and neurologically intact survival increased from 587 cases (age-adjusted proportion, 3.3% [95% CI, 3.0%-3.5%]) to 1710 cases (8.2% [95% CI, 7.8%-8.6%]). The rates of bystander chest compression increased from 38.6% to 50.9%, bystander-only defibrillation increased from 0.1% to 2.3%, bystander defibrillation combined with EMS defibrillation increased from 0.1% to 1.4%, and EMS-only defibrillation decreased from 26.6% to 23.5%. Performance of bystander chest compression, compared with no bystander chest compression, was associated with increased neurologically intact survival (8.4% [6594 survivors/78,592 cases] vs 4.1% [3595 survivors/88,720 cases]; odds ratio [OR], 1.52 [95% CI, 1.45-1.60]). Compared with EMS-only defibrillation (15.0% [6445 survivors/42,916 cases]), bystander-only defibrillation (40.7% [931 survivors/2287 cases]) was associated with increased neurologically intact survival (OR, 2.24 [95% CI, 1.93-2.61]), as was combined bystander and EMS defibrillation (30.5% [444 survivors/1456 cases]; OR, 1.50 [95% CI, 1.31-1.71]), whereas no defibrillation (2.0% [2369 survivors/120,653 cases]) was associated with reduced survival (OR, 0.43 [95% CI, 0.39-0.48]). CONCLUSIONS AND RELEVANCE In Japan, between 2005 and 2012, the rates of bystander chest compression and bystander defibrillation increased and were associated with increased odds of neurologically intact survival.

Abstract
BACKGROUND It is increasingly clear that asthma is not a single disease, but a disorder with vast heterogeneity in pathogenesis, severity, and treatment response. To date, 30 genomewide association studies (GWASs) of asthma have been performed, including by our group. However, most gene variants identified so far confer relatively small increments in risk and explain only a small proportion of familial clustering. OBJECTIVE To identify additional genetic determinants of susceptibility to asthma using a selected Japanese population with reduced tobacco smoking exposure. METHODS We performed a GWAS by genotyping a total of 480 098 single-nucleotide polymorphisms (SNPs) for a Japanese cohort consisting of 734 healthy controls and 240 patients with asthma who had smoked for no more than 10 pack-years. The SNP with the strongest association was genotyped in two other independent Japanese cohorts consisting of a total of 531 healthy controls and 418 patients with asthma who had smoked for no more than 10 pack-years. For the hyaluronan synthase 2 (HAS2) gene, we investigated SNP-gene associations using an expression quantitative trait loci (eQTL) database and also analysed its gene expression profiles in 13 different normal tissues. RESULTS In the discovery GWAS, a SNP located upstream of HAS2, rs7846389, showed the strongest statistical significance (P = 1.43 × 10(-7) ). In the two independent replication cohorts, rs7846389 was consistently associated with asthma (nominal P = 0.0152 and 0.0478 in the first and second replication cohorts, respectively). In the meta-analysis, association of rs7846389 with susceptibility to asthma reached the level of genomewide significance (P = 7.92 × 10(-9) ). This variant was strongly correlated with HAS2 mRNA expression. The strongest expression of the gene was detected in the lung. CONCLUSIONS Our study identified HAS2 as a novel candidate gene for susceptibility to adult asthma.

Abstract
The use of transmission near infrared spectroscopy (TNIRS) is of particular interest in the pharmaceutical industry. This is because TNIRS does not require sample preparation and can analyze several tens of tablet samples in an hour. It has the capability to measure all relevant information from a tablet, while still on the production line. However, TNIRS has a narrow spectrum range and overtone vibrations often overlap. To perform content uniformity testing in tablets by TNIRS, various properties in the tableting process need to be analyzed by a multivariate prediction model, such as a Partial Least Square Regression modeling. One issue is that typical approaches require several hundred reference samples to act as the basis of the method rather than a strategically designed method. This means that many batches are needed to prepare the reference samples; this requires time and is not cost effective. Our group investigated the concentration dependence of the calibration model with a strategic design. Consequently, we developed a more effective approach to the TNIRS calibration model than the existing methodology.

Abstract
OBJECTIVES Excessive acetabular coverage is the most common cause of pincer-type femoroacetabular impingement. To date, an association between acetabular over-coverage and genetic variations has not been studied. In this study we investigated the association between single nucleotide polymorphisms (SNPs) of paralogous Homeobox (HOX)9 genes and acetabular coverage in Japanese individuals to identify a possible genetic variation associated with acetabular over-coverage. METHODS We investigated 19 total SNPs in the four HOX9 paralogs, then focused in detail on seven of those located in the 3' untranslated region of HOXB9 (rs8844, rs3826541, rs3826540, rs7405887, rs2303485, rs2303486, rs79931349) using a case-control association study. The seven HOXB9 SNPs were genotyped in 316 subjects who had all undergone radiological examination. The association study was performed by both single-locus and haplotype-based analyses. RESULTS The genotype and allele frequencies of the five HOXB9 SNPs showed significant association with acetabular over-coverage compared with controls (rs7405887 OR = 3.16, p = 5.29E-6, 95% CI 1.91 to 5.25). A significant difference was also detected when haplotypes were evaluated (OR = 2.59, p = 2.61E-5, 95% CI 1.65 to 4.08). The two HOXB9 SNPs (rs2303485, rs2303486) were associated with decreased acetabular coverage (rs2303485 OR = 0.524, p = 0.0091, 95% CI 0.322 to 0.855; rs2303486 OR = 0.519, p = 0.011, 95% CI 0.312 to 0.865). CONCLUSIONS The five HOXB9 SNPs (rs8844, rs3826541, rs3826540, rs7405887, rs79931349) were associated with acetabular over-coverage. On the other hand, the two SNPs (rs2303485 and rs2303486) were associated with the lower acetabular coverage. The association of rs2303486 would be consistent with the previous study. Therefore, the HOXB9 SNPs might be involved in the morphogenesis of acetabular coverage, and could be an independent risk factor for developing pincer-type femoroacetabular impingement.

Abstract
Aim Bystander cardiopulmonary resuscitation including automated external defibrillator use increases the chance of survival after out-of-hospital cardiac arrest. However, bystanders may be distressed by witnessing out-of-hospital cardiac arrest and may hesitate to initiate cardiopulmonary resuscitation. The present study examined factors associated with layperson confidence in carrying out resuscitation of out-of-hospital cardiac arrest patients. Methods We carried out a cross-sectional survey in February 2012. Laypeople were asked about background characteristics, whether they had performed cardiopulmonary resuscitation, had received cardiopulmonary resuscitation training, were aware of the location of the neighborhood automated external defibrillator, and felt confident in performing resuscitation, and their potential emotional distress if a resuscitation attempt were to prove unsuccessful. Results Participants comprised 4,853 respondents. Of these, 2,372 (49%) had received cardiopulmonary resuscitation training, and 3,607 (74%) knew where the neighborhood automated external defibrillator was located. Confidence in performing chest compressions was reported by 2,667 (55%), confidence in performing rescue breathing by 2,498 (52%), and confidence in using an automated external defibrillator by 2,822 (58%). Potential emotional distress if a resuscitation attempt proved unsuccessful was reported by 4,247 (88%). Multivariate regression analysis showed that having carried out cardiopulmonary resuscitation, having received cardiopulmonary resuscitation training, and awareness of the neighborhood automated external defibrillator location were significantly associated with confidence in performing cardiopulmonary resuscitation. Conclusions Our results suggest that more extensive cardiopulmonary resuscitation training and information regarding neighborhood automated external defibrillator locations may increase layperson confidence in initiating resuscitation.

Abstract
Intestinal abnormalities and ischemia are medical conditions in which inflammation and injury of the intestine are caused by inadequate blood supply. Acute ischemia of the small bowel can be life-threatening. Computed tomography (CT) is currently a gold standard for the diagnosis of acute intestinal ischemia in the emergency department. However, the assessment of the diagnostic performance of CT findings in the detection of intestinal abnormalities and ischemia has been a difficult task for both radiologists and surgeons. Little effort has been found in developing computerized systems for the automated identification of these types of complex gastrointestinal disorders. In this paper, a geostatistical mapping of spatial uncertainty in CT scans is introduced for medical image feature extraction, which can be effectively applied for diagnostic detection of intestinal abnormalities and ischemia from control patterns. Experimental results obtained from the analysis of clinical data suggest the usefulness of the proposed uncertainty mapping model.

Abstract
Upper airway viral infection in patients with airway allergy often exacerbates olfactory dysfunction, but the mechanism for this exacerbation remains unclear. Here, we examined the effects of respiratory syncytial virus (RSV) infection, in the presence or absence of airway allergy, on olfactory receptor neurons (ORNs) and their progenitors in mice. Immunohistological analyses revealed that cockroach allergen (CRA)-induced airway allergy alone did not affect the number of OMP(+) mature ORNs and SOX2(+) ORN progenitors. Intranasal RSV line 19 infection in allergy-free mice resulted in a transient decrease in SOX2(+) ORN progenitors without affecting OMP(+) ORNs. In contrast, the RSV-induced decrease in SOX2(+) ORN progenitors was exacerbated and prolonged in allergic mice, which resulted in eventual loss of OMP(+) ORNs. In the allergic mice, reduction of RSV in the olfactory epithelium was delayed as compared with allergy-free mice. These results suggest that ORN progenitors were impaired by RSV infection and that airway allergy exacerbated damage to ORN progenitors by reducing viral clearance.

Abstract
Pancreatic β cell-derived vascular endothelial growth factor A (VEGF-A) contributes to normal β cell function. We therefore hypothesized that non-β cell-derived VEGF-A may affect its properties in adult mice.We generated transgenic mice expressing human VEGF-A (hVEGF-A) in a visceral smooth muscle cell (SMC)-dominant manner under the control of the transgelin (Tagln/SM22α) promoter via a tamoxifen-induced Cre/loxP recombination system (SM-CreER(T2)/hVEGF mice).SM-CreER(T2)/hVEGF mice received tamoxifen orally followed by microscopic examination of their pancreas 4 weeks after the hVEGF-A induction. The number of clusters of insulin-producing cells (IPCs) in islets, pancreatic ducts, and individual IPCs were counted.The number of small IPC clusters (100-215 μm(2)) in the pancreas increased significantly in SM-CreER(T2)/hVEGF mice compared with SM-CreER(T2)(Ki) mice (473 out of 1 992 counts vs. 199 out of 976 counts, p<0.05), although total IPC area and the number of pancreatic duct IPCs, in proportion to exocrine area, were similar between the 2 groups. Although most small IPC clusters observed in SM-CreER(T2)/hVEGF mice were not accompanied by α and/or δ cells, some were attached to a single or a few α cells. An STZ-induced diabetic state in SM-CreER(T2)/hVEGF mice was slightly ameliorated, with only one point of significance 12 weeks after STZ administration, compared with SM-CreER(T2)(Ki) mice.Upregulation of non-β cell-derived VEGF-A may alter the composition of pancreatic IPCs by increasing the number of small IPC clusters. These findings provide new information on the role of non-β cell-derived VEGF-A to IPC regeneration and insulin production.

Abstract
Several radiological methods of measuring anteversion of the acetabular component after total hip replacement (THR) have been described. These studies used different definitions and reference planes to compare methods, allowing for misinterpretation of the results. We compared the reliability and accuracy of five current methods using plain radiographs (those of Lewinnek, Widmer, Liaw, Pradhan, and Woo and Morrey) with CT measurements, using the same definition and reference plane. We retrospectively studied the plain radiographs and CT scans in 84 hips of 84 patients who underwent primary THR. Intra- and inter-observer reliability were high for the measurement of inclination and anteversion with all methods on plain radiographs and CT scans. The measurements of inclination on plain radiographs were similar to the measurements using CT (p = 0.043). The mean difference between CT measurements was 0.6° (-5.9° to 6.8°). Measurements using Widmer’s method were the most similar to those using CT (p = 0.088), with a mean difference between CT measurements of -0.9° (-10.4° to 9.1°), whereas the other four methods differed significantly from those using CT (p < 0.001). This study has shown that Widmer’s method is the best for evaluating the anteversion of the acetabular component on plain radiographs. Cite this article: Bone Joint J 2014; 96-B:597–603.

Abstract
Background Evaluation of computed tomography (CT) for the diagnosis of intestinal wall abnormalities and ischemia is important for clinical decision making in patients with acute abdominal pain to which if surgery should be performed in the emergency department. Interpretation of such information on CT is usually based on visual assessment by medical professionals and still remains a challenge in a variety of settings of the medical emergency care. This paper reports a pilot study in the implementation of image processing methods for automated detection of intestinal wall abnormalities and bowel ischemia, which can be of a potential application for CT-based detection of the intestinal disease. Methods CT scans of 3 patients of ischemia, one benign and one control subjects were used in this study. Statistical and geometrical features of the CT scans were extracted for pattern classification using two distance measures and the k-nearest neighbor algorithm. The automated detection of intestinal abnormalities and ischemia was carried out using labeled data from the training process with various proportions of training and testing samples to validate the results. Results Detection rates of intestinal ischemia and abnormalities are promising in terms of sensitivity and specificity, where the sensitivity is higher than the specificity in all test cases. The overall classification accuracy between the diseased and control subjects can be as high as 100% when all CT scans were included for measuring the difference between a cohort of three patients of ischemia and a single control subject. Conclusion The proposed approach can be utilized as a computer-aided tool for decision making in the emergency department, where the availability of expert knowledge of the radiologist and surgeon about this complex bowel disease is limited.

Abstract
OBJECTIVES It is unclear how much the length of a cardiopulmonary resuscitation (CPR) training program can be reduced without ruining its effectiveness. The authors aimed to compare CPR skills 6 months and 1 year after training between shortened chest compression-only CPR training and conventional CPR training. METHODS Participants were randomly assigned to either the compression-only CPR group, which underwent a 45-minute training program consisting of chest compressions and automated external defibrillator (AED) use with personal training manikins, or the conventional CPR group, which underwent a 180-minute training program with chest compressions, rescue breathing, and AED use. Participants' resuscitation skills were evaluated 6 months and 1 year after the training. The primary outcome measure was the proportion of appropriate chest compressions 1 year after the training. RESULTS A total of 146 persons were enrolled, and 63 (87.5%) in the compression-only CPR group and 56 (75.7%) in the conventional CPR group completed the 1-year evaluation. The compression-only CPR group was superior to the conventional CPR group regarding the proportion of appropriate chest compression (mean ± SD = 59.8% ± 40.0% vs. 46.3% ± 28.6%; p = 0.036) and the number of appropriate chest compressions (mean ± SD = 119.5 ± 80.0 vs. 77.2 ± 47.8; p = 0.001). Time without chest compression in the compression-only CPR group was significantly shorter than that in the conventional CPR group (mean ± SD = 11.8 ± 21.1 seconds vs. 52.9 ± 14.9 seconds; p < 0.001). CONCLUSIONS The shortened compression-only CPR training program appears to help the general public retain CPR skills better than the conventional CPR training program.

Abstract
OBJECTIVE We conducted a multicenter retrospective survey of patients poisoned by synthetic chemicals (SCs) in Japan. METHODS Letters were sent to 467 emergency facilities requesting participation in the study, and questionnaires were mailed to facilities that agreed to participate. Patients The study participants were patients who were transported to emergency facilities between January 2006 and December 2012 after consuming SC-containing products. RESULTS We surveyed 518 patients from 60 (12.8%) facilities. Most patients were male (82.0%), in their 20s or 30s (80.5%), and had inhaled SCs (87.5%) contained in herbal products (86.0%). Harmful behavior was observed at the scene of poisoning for 56 patients (10.8%), including violence to others or things in 32, traffic accidents in seven, and self-injury or suicide attempts in four. Other than physical and neuropsychiatric symptoms, some patients also had physical complications, such as rhabdomyolysis (10.0%). Of the 182 patients (35.1%) admitted to hospitals, including 29 (5.6%) who needed respirators, all of the 21 (4.1%) hospitalized for at least seven days were male, and 20 had physical complications (rhabdomyolysis, 12; liver dysfunction, 5; renal dysfunction, 11; and physical injuries, 3). Most patients (95.6%) completely recovered, although 10 (1.9%) were transferred to a psychiatric department or hospital, and three (0.6%) were handed over to the police due to combative or violent behavior. SCs such as synthetic cannabinoids, synthetic cathinones, or methoxetamine were detected in 20 product samples. CONCLUSION Consuming products containing SCs can result in physical complications, including rhabdomyolysis, injuries, and physical or neuropsychiatric symptoms, which may require active interventions, such as respirator use or prolonged hospitalization.

Abstract
OBJECTIVES To evaluate the effectiveness of pre-hospital adrenaline (epinephrine) administered by emergency medical services to patients with out of hospital cardiac arrest. DESIGN Controlled propensity matched retrospective cohort study, in which pairs of patients with or without (control) adrenaline were created with a sequential risk set matching based on time dependent propensity score. SETTING Japan's nationwide registry database of patients with out of hospital cardiac arrest registered between January 2007 and December 2010. PARTICIPANTS Among patients aged 15-94 with out of hospital cardiac arrest witnessed by a bystander, we created 1990 pairs of patients with and without adrenaline with an initial rhythm of ventricular fibrillation or pulseless ventricular tachycardia (VF/VT) and 9058 pairs among those with non-VF/VT. MAIN OUTCOME MEASURES Overall and neurologically intact survival at one month or at discharge, whichever was earlier. RESULTS After propensity matching, pre-hospital administration of adrenaline by emergency medical services was associated with a higher proportion of overall survival (17.0% v 13.4%; unadjusted odds ratio 1.34, 95% confidence interval 1.12 to 1.60) but not with neurologically intact survival (6.6% v 6.6%; 1.01, 0.78 to 1.30) among those with VF/VT; and higher proportions of overall survival (4.0% v 2.4%; odds ratio 1.72, 1.45 to 2.04) and neurologically intact survival (0.7% v 0.4%; 1.57, 1.04 to 2.37) among those with non-VF/VT. CONCLUSIONS Pre-hospital administration of adrenaline by emergency medical services improves the long term outcome in patients with out of hospital cardiac arrest, although the absolute increase of neurologically intact survival was minimal.

WHAT IS KNOWN AND OBJECTIVES Belimumab is a recombinant human monoclonal antibody that binds and antagonizes the biological activity of soluble B-lymphocyte stimulator (BLyS) protein. BLyS appears to play a role in the pathogenesis of systemic lupus erythematosus, and the biological profile of belimumab suggests that it may have a therapeutic benefit in the treatment for the disease. In this healthy Japanese subjects study, we investigated the pharmacokinetics and safety of a single subcutaneous and intravenous injection of belimumab administered as a 200 mg/mL liquid formulation. METHODS This was an open-label, randomized, parallel-group, single-dose study in healthy Japanese subjects. Each subject received a single intravenous infusion or a subcutaneous injection of 200 mg belimumab. The pharmacokinetic parameters and safety parameters including local tolerance (injection site), biomarkers, immunogenicity and adverse events were evaluated up to 70 days post-dosing. RESULTS After a single intravenous or a subcutaneous administration of 200 mg belimumab, all 16 subjects completed the study. There were no serious adverse events or adverse events related to injection site reactions. All seven adverse events were considered mild or moderate in intensity and deemed unrelated to belimumab except for cellulitis following intravenous administration. The bioavailability of the single subcutaneous dose of 200 mg belimumab in the subjects was estimated to be 77·5%. Time to the maximum serum concentration after subcutaneous injection was 6·5 days (median). The geometric mean terminal half-life was comparable between the two administration routes (17·7 days intravenous and 15·9 days subcutaneous). Serum immunoglobulin G level decreased slightly after each treatment. No subjects were found to produce antibelimumab antibodies. WHAT IS NEW AND CONCLUSIONS A favourable absolute bioavailability in healthy Japanese subjects was seen following a subcutaneous injection of 200 mg belimumab. Considering the intersubject variability, exposures were consistent with those previously observed in healthy non-Japanese subjects. Safety and biomarker data were also consistent with previous non-Japanese clinical studies.
