OBJECTIVES: Appropriate antibiotic prescriptions for outpatients with acute respiratory tract infections (ARTIs) are urgently needed in Japan. However, the empirical proof of this need is under-documented. Therefore, we aimed to determine antibiotic prescription rates, and the proportions of antibiotic classes prescribed for Japanese patients with ARTIs. METHODS: We analysed health insurance claims data over 2013-2015 among Japanese patients aged <75 years and determined the following indicators: 1) visit rates for patients with ARTIs and antibiotic prescription rates per 1000 person-years, and 2) proportion of visits by antibiotic-prescribed patients with ARTIs. We defined broad-spectrum antibiotics using the WHO Anatomical Therapeutic Chemical classification 4 level codes. RESULTS: Among 8.65 million visits due to ARTIs at 6859 hospitals and 62,024 physicians' offices, the visit rate and antibiotic prescription rate per 1000 person-years were 990.6 (99% confidence interval [CI], 989.4-991.7) and 532.4 (99% CI, 531.6-533.3), respectively. The visit rates for patients aged 0-17, 18-59, and 60-74 years were 2410.0 (99% CI, 2407.2-2412.9), 683.6 (99% CI, 682.7-684.6), and 682.1 (99% CI, 678.2-686.0), and antibiotic prescription rates were 1093.3 (99% CI, 1091.4-1095.2), 434.1 (99% CI, 433.4-434.9), and 353.4 (99% CI, 350.7-356.1), respectively. The overall proportion of antibiotic prescriptions for ARTI visits was 52.7% and 91.3% of the antibiotics prescribed were broad-spectrum. CONCLUSIONS: Both the visit rates and antibiotic prescription rates for ARTIs were high in this Japanese cohort. The proportion of antibiotic prescriptions exceeded that recommended in the clinical guidelines. Thus, there might be a scope for reducing the current antibiotic prescription rate in Japan.

Arterial calcification, a risk factor of cardiovascular events, develops with differentiation of vascular smooth muscle cells (VSMCs) into osteoblast-like cells. Cyclophilin A (CypA) is a peptidyl-prolyl isomerase involved in cardiovascular diseases such as atherosclerosis and aortic aneurysms, and rho-associated protein kinase (ROCK) is involved in the pathogenesis of vascular calcification. CypA is secreted in a ROCK activity-dependent manner and works as a mitogen via autocrine or paracrine mechanisms in VSMCs. We examined the involvement of the ROCK-CypA axis in VSMC calcification induced by inorganic phosphate (Pi), a potent cell mineralization initiator. We found that Pi stimulated ROCK activity, CypA secretion, extracellular signal-regulated protein kinase (ERK) 1/2 phosphorylation, and runt-related transcription factor 2 expression, resulting in calcium accumulation in rat aortic smooth muscle cells (RASMCs). The ROCK inhibitor Y-27632 significantly suppressed Pi-induced CypA secretion, ERK1/2 phosphorylation, and calcium accumulation. Recombinant CypA was found to be associated with increased calcium accumulation in RASMCs. Based on these results, we suggest that autocrine CypA is mediated by ROCK activity and is involved in Pi-induced ERK1/2 phosphorylation following calcification signaling in RASMCs.

Language：English Publishing type：Research paper (scientific journal)

Background:
Globally, the number of deaths is estimated to increase to 74 million per year by 2030. Place of death (PoD) is increasingly being recognized as an important aspect of end-of-life care. However, recent trends in PoD in Japan, one of the super-aged societies, are unknown.
Objective:
To analyze trends in PoD in Japan over two decades.
Design:
Population-based retrospective observational study.
Setting:
All deaths reported in Japan, 1998-2017. PoD was defined as hospital, nursing home, or own home.
Results:
All Japanese decedents (∼22.6 million) over the past 20 years were analyzed. The proportion of hospital deaths was consistently high (>80%), with a significant decreasing trend from the mid-2000s. Although the proportion of deaths at home decreased in the first half of the study period, they later increased. There was a low proportion of deaths in nursing homes compared to other places of death; however, the proportion increased continually throughout the study period, particularly among women. In 2015, more women died in nursing homes than at home. Although the proportion of hospital deaths declined in the second half of the study period, their overall number continued to increase, reflecting an increase in total deaths in Japan.
Conclusions:
This study highlighted rapid changes in trends in PoD in Japan, and the need to consider affordable end-of-life care in Japan as well as other countries with aging populations. The findings from this long-term epidemiological study provide important insights on this issue.

Proton pump inhibitors (PPIs) have been used worldwide to treat gastrointestinal disorders. A recent study showed that long-term use of PPIs caused iron deficiency; however, it is unclear whether PPIs affect iron metabolism directly. We investigated the effect of PPIs on the peptide hepcidin, an important iron regulatory hormone. First, we used the FDA Adverse Event Reporting System database and analyzed the influence of PPIs. We found that PPIs, as well as H2 blockers, increased the odds ratio of iron-deficient anemia. Next, HepG2 cells were used to examine the action of PPIs and H2 blockers on hepcidin. PPIs augmented hepcidin expression, while H2 blockers did not. In fact, the PPI omeprazole increased hepcidin secretion, and omeprazole-induced hepcidin upregulation was inhibited by gene silencing or the pharmacological inhibition of the aryl hydrocarbon receptor. In mouse experiments, omeprazole also increased hepatic hepcidin mRNA expression and blood hepcidin levels. In mice treated with omeprazole, protein levels of duodenal and splenic ferroportin decreased. Taken together, PPIs directly affect iron metabolism by suppressing iron absorption through the inhibition of duodenal ferroportin via hepcidin upregulation. These findings provide a new insight into the molecular mechanism of PPI-induced iron deficiency.

Language：English Publishing type：Research paper (scientific journal)

Background: Prasugrel inhibits platelet aggregation more potently and exerts therapeutic action faster than clopidogrel. In the global phase III trial conducted in Western and South American countries that excluded Asian countries, prasugrel reduced ischemic events but increased hemorrhagic risk compared with clopidogrel in patients with acute coronary syndrome scheduled for percutaneous coronary intervention. In the Japanese phase III trial for similar patients, the efficacy of prasugrel compared with clopidogrel was comparable to the global trial, but the safety could not be confirmed because of an insufficient number of patients. Furthermore, given the strict enrollment criteria, the results of these trials may not be applicable to routine clinical practice. Accordingly, we compared the hemorrhagic risk of prasugrel and clopidogrel in real-world settings by analyzing adverse drug event reports in post-marketing stages provided by the Japanese regulatory authorities and the U.S. Food and Drug Administration (FDA). Methods: We analyzed a total of 3,970 reports for prasugrel (n = 518) or clopidogrel (n = 3,452) between 2014 and 2017 in the Japanese Adverse Drug Event Report (JADER) and a total of 91,914 reports for either prasugrel (n = 5,992) or clopidogrel (n = 85,922) between 2009 and 2019 in the FDA Adverse Event Reporting System (FAERS). Results: In JADER and FAERS, prasugrel was more frequently and significantly associated with hemorrhagic event reports than clopidogrel. After adjustment for known confounders including age, sex, and concomitant medications (aspirin, anticoagulants, and proton pump inhibitors), the hemorrhagic risk of prasugrel compared with clopidogrel remained significant (adjusted reporting odds ratios [95% CI] for total, intracranial, and gastrointestinal hemorrhagic events = 2.42 [1.97-2.96], 2.45 [1.85-3.24], and 2.27 [1.73-2.97] in JADER, and 2.21 [2.09-2.34], 1.21 [1.09-1.33], and 1.41 [1.29-1.54] in FAERS). Conclusions: The hemorrhagic risk was found to be greater with prasugrel than clopidogrel in real-world patients, including Japanese patients.

Proceedings for Annual Meeting of The Japanese Pharmacological Society 93 2 - O-060 2020

Language：Japanese Publisher：Japanese Pharmacological Society

Background: Ferroptosis has been identified as iron-dependent regulated cell death, and it participates with a various disorder including kidney disease. Cisplatin, a classical anti-cancer drug, causes nephrotoxicity, which is inhibited by iron chelator. In the present study, we examined the involvement of ferroptosis on cisplatin-induced nephrotoxicity.Methods: We used male mice with cisplatin-induced nephrotoxicity that were pretreated with vehicle or a ferroptosis inhibitor. Mice were sacrificed at 48 hours later. Results: Cisplatin administration actually augmented ferrous iron and hydroxyl radical production in the kidney. Cisplatin-induced COX-2 expression, as well as lipid peroxide, was increased by cisplatin-treated kidney. An inhibitor of ferroptosis also suppressed cisplatin-induced increased of COX-2 expression and lipid peroxide. Mice with cisplatin administration developed kidney injury with renal dysfunction, and showed augmented oxidative stress, increased apoptosis, and elevated inflammatory cytokines. However, most of these symptoms were suppressed by a ferroptosis inhibitor.Conclusion: Ferroptosis is suggested to involve cisplatin-induced nephrotoxicity.

Dementia is a major public health concern in ageing societies. Although the population of Japan is among the most aged worldwide, long-term trends in the place of death (PoD) among patients with dementia is unknown. In this Japanese nationwide observational study, we analysed trends in PoD using the data of patients with dementia who were aged ≥65 years and died during 1999-2016. Trends in the crude death rates and PoD frequencies were analysed using the Joinpoint regression model. Changes in these trends were assessed using the Joinpoint regression analysis in which significant change points, the annual percentage change (APC) and average APCs (AAPC) in hospitals, homes, or nursing homes were estimated. During 1999-2016, the number of deaths among patients with dementia increased from 3,235 to 23,757 (total: 182,000). A trend analysis revealed increased mortality rates, with an AAPC of 8.2% among men and 9.3% among women. Most patients with dementia died in the hospital, although the prevalence of hospital deaths decreased (AAPC: -1.0%). Moreover, the prevalence of nursing home deaths increased (AAPC: 5.6%), whereas the prevalence of home deaths decreased (AAPC: -5.8%). These findings support a reconsideration of the end-of-life care provided to patients with dementia.

OBJECTIVES: Fall-related mortality among older adults is a major public health issue, especially for ageing societies. This study aimed to investigate current trends in fall-related mortality in Japan using nationwide population-based data covering 1997-2016. DESIGN: We analysed fall-related deaths among older persons aged ≥65 years using the data provided by the Japanese Ministry of Health, Labour and Welfare. RESULTS: The crude and age-standardised mortality rates were calculated per 100 000 persons by stratifying by age (65-74, 75-84 and ≥85 years) and sex. To identify trend changes, a joinpoint regression model was applied by estimating change points and annual percentage change (APC). The total number of fall-related deaths in Japan increased from 5872 in 1997 to 8030 in 2016, of which 78.8% involved persons aged ≥65 years. The younger population (65-74 years) showed continuous and faster-decreasing trends for both men and women. Average APC among men aged ≥75 years did not decrease. Among middle-aged and older women (75-84 and ≥85 years) decreasing trends were observed. Furthermore, the age-adjusted mortality rate of men was approximately twice that of women, and it showed a faster decrease for women. CONCLUSIONS: Although Japanese healthcare has shown improvement in preventing fall-related deaths over the last two decades, the crude mortality for those aged over 85 years remains high, indicating difficulty in reducing fall-related deaths in the super-aged population. Further investigations to uncover causal factors for falls in older populations are required.

Language：English Publishing type：Research paper (scientific journal)

PURPOSE: Appropriate use of vancomycin (VCM) is important in preventing acute kidney injury (AKI). Because of the high frequency of VCM use for febrile neutropenia and concomitant use of other nephrotoxic drugs, haematologic patients have a different nephrotoxic background compared with patients with other diseases. Therefore, it is unclear whether the risk factors of VCM-induced AKI identified in other patient groups are also applicable to haematologic patients. Herein, we performed a single-centre retrospective analysis to identify the factors associated with VCM-induced AKI in haematologic patients. METHODS: We retrospectively analysed 150 haematologic patients to whom VCM was administered between April 2010 and March 2018 at Tokushima University Hospital. VCM-induced AKI was defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. Multivariate logistic regression analyses were performed to identify risk factors for VCM-induced AKI. RESULTS: Seventeen patients had VCM-induced AKI. Multivariate analysis revealed that the risk factors of VCM-induced AKI were an initial VCM trough concentration of > 15 mg/L and concomitant use of tazobactam/piperacillin (TAZ/PIPC) and liposomal amphotericin B (L-AMB). Patients with an initial VCM trough concentration of < 10 mg/L showed significantly lower efficacy in febrile neutropenia. Interestingly, concomitant L-AMB use increased the incidence of VCM-induced AKI in a VCM concentration-dependent manner, whereas concomitant TAZ/PIPC increased the incidence in a VCM concentration-independent manner. CONCLUSIONS: The optimal initial VCM trough concentration was 10-15 mg/L in haematologic patients, considering safety and effectiveness. There were differences in the effect of VCM-induced AKI between nephrotoxic drugs.

BACKGROUND: Oral anticoagulants use has increased rapidly, internationally. Here we look at risks and benefits, based on Japanese data, of therapy with low risk non-valvular atrial fibrillation patients. OBJECTIVES: Using a health insurance claims data set we assessed: (i) oral anticoagulants usage in Japan, and (ii) efficacy and safety of dabigatran compared with warfarin, in Japanese patients with non-valvular atrial fibrillation, aged 18-74 years. METHODS: We identified 4380 non-valvular atrial fibrillation patients treated with anticoagulants between 1 January 2005, and 28 February 2014, and estimated the adjusted hazard ratio for stroke or systemic embolism, and any hemorrhagic event (Cox proportional hazards regression model with stabilized inverse probability treatment weighting). RESULTS: The data included 101 989 anticoagulant prescriptions for 4380 patients, of which direct oral anticoagulants increased to 40.0% of the total by the end of the study. After applying exclusion criteria, 1536 new non-valvular atrial fibrillation patients were identified, including 1071 treated with warfarin and 465 with dabigatran. Mean ages were 56.11 ± 9.70 years for warfarin, and 55.80 ± 9.65 years for dabigatran. The adjusted hazard ratio (95% confidence interval), comparing dabigatran with warfarin, was 0.48 (0.25-0.91) for stroke or systemic embolism, and 0.91 (0.60-1.39) for any hemorrhage including intracranial and gastrointestinal. CONCLUSIONS: Number of patients prescribed direct oral anticoagulants steadily increased, and incidence of all-cause bleeding related to dabigatran was similar to warfarin, in our study population of younger non-valvular atrial fibrillation patients. Dabigatran, compared with warfarin, generally reduced risk of all-cause stroke and systemic embolism.

PURPOSE: Epirubicin and cyclophosphamide (EC) therapy, a major chemotherapy for patients with early-stage breast cancer, has a low risk (< 10%) of febrile neutropenia (FN). However, data used in reports on the incidence rate of FN were derived primarily from non-Asian populations. In this study, we investigated the FN incidence rate using EC therapy among Japanese patients with breast cancer and evaluated the significance of prophylactic administration of granulocyte colony-stimulating factor (G-CSF). METHODS: We evaluated medical records of patients with early-stage breast cancer who had been treated with EC therapy as neoadjuvant or adjuvant therapy between November 2014 and July 2018. RESULTS: The incidence rate of FN was 23.9%. In patients who received G-CSF as primary prophylaxis, FN expression was completely suppressed. The incidence rate of severe leucopenia/neutropenia, emergency hospitalization, and the use of antimicrobial agents were low in patients receiving primary prophylaxis with G-CSF compared with those not receiving G-CSF (27.3% vs. 64.8%, 9.1% vs. 27.3%, and 27.3% vs. 71.6%, respectively). Furthermore, in all patients who received primary prophylaxis with G-CSF, a relative dose intensity > 85% using EC therapy was maintained. CONCLUSION: The incidence of FN in EC therapy among Japanese patients was higher than expected, EC therapy appears to be a high-risk chemotherapy for FN, and prophylactic administration of G-CSF is recommended. Maintaining high therapeutic intensity is associated with a positive prognosis for patients with early breast cancer, and prophylactic administration of G-CSF is likely to be beneficial in treatment involving EC therapy.
