RESUMO
INTRODUCTION: Comprehensive evidence about the burden of infectious diseases in the Western Pacific Region is scarce. We thus examined the disease burden of infectious diseases in Japan in terms of disability-adjusted life years (DALYs). METHODS: We extracted national claims data from Japan's universal health insurance system to estimate the burden of disease for selected infections between 2015 and 2020 using DALYs. The mortality rate, disability duration and severity weight of each disease were estimated based on national data and literature reviews. RESULTS: Disease burden per 100,000 population was 1307.0 in 2015 and 972.1 in 2020 for bloodstream infections (BSI), 796.5 DALYs in 2015 and 498.9 DALYs in 2020 for pneumonia, 171.5 in 2015 and 149.4 in 2020 for meningitis and 11.6 in 2015 and 11.4 in 2020 for urinary tract infections (UTI). Only surgical site infections (SSI) showed a slightly increasing trend over the 5-year period, from 2.2 in 2015 to 2.8 in 2020. CONCLUSIONS: Our results showed that the disease burden of the five major infectious diseases was higher in Japan than in other countries. However, while the burden of SSI increased, the burden of pneumonia, meningitis, BSI and UTI gradually decreased year on year. The possible causes of the decreased morbidity should be examined in future work.
RESUMO
The development of the mutant omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the coronavirus disease 2019 (COVID-19) pandemic raised the importance of reevaluating the risk and benefit of COVID-19 vaccines. With a decision tree model, we calculated the benefit-risk ratio and the benefit-risk difference of receiving monovalent messenger RNA (mRNA) COVID-19 vaccine (primary 2 doses, a third dose, and a fourth dose) in the 4-5 months after vaccination using quality-adjusted life years. The analysis was stratified by age, sex, and the presence of comorbidity. Evidence from peer-reviewed publications and gray literature was reviewed on September 16, 2022, to inform the study. Benefit-risk ratios for receipt of the BNT162b2 vaccine (Pfizer-BioNTech) ranged from 6.8 for males aged 12-17 years without comorbidity for the primary doses to 221.3 for females aged ≥65 years with comorbidity for the third dose. The benefit-risk ratios for receipt of the mRNA-1273 vaccine (Moderna) ranged from 7.2 for males aged 18-29 years without comorbidity for the primary doses to 101.4 for females aged ≥65 years with comorbidity for the third dose. In all scenarios of the one-way sensitivity analysis, the benefit-risk ratios were more than 1, irrespective of age, sex, comorbidity status, and type of vaccine, for both primary and booster doses. The benefits of mRNA COVID-19 vaccines in protecting against the omicron variant outweigh the risks, irrespective of age, sex, and comorbidity.

Congenital cytomegalovirus infection is the most common congenital infection. Using a decision tree model, cost-effectiveness of maternal screening with subsequent prenatal valacyclovir treatment and newborn screening with neonatal valganciclovir treatment was evaluated. The incremental cost-effectiveness ratio (ICER) was calculated for (1) universal maternal antibody screening with prenatal valacyclovir treatment compared to targeted newborn screening, and (2) universal newborn screening with postnatal valganciclovir treatment compared to targeted newborn screening. We performed a one-way sensitivity analysis. Compared to targeted newborn screening, the ICERs for universal newborn screening and maternal screening were 2 966 296 Japanese Yen (JPY) (21 188 USD) and 1 026 984 JPY (7336 USD), respectively. In all scenarios in the one-way sensitivity analysis, the ICERs of the maternal screening and the universal newborn screening strategies were less than three gross domestic product per capita compared with the targeted newborn screening strategy. Both maternal and universal newborn screening strategies may be cost-effective than a targeted newborn screening program. The potential utility of the maternal screening with valacyclovir treatment strategy, while potentially cost effective in regions with lower baseline seroprevalence rates, requires further study as the modeling was based on limited evidence.

BACKGROUND: Solid-organ transplant recipients are at increased risk of developing human papillomavirus-related diseases. METHODS: To evaluate the immunogenicity of a quadrivalent vaccine, a prospective observational study included females aged 12-19 years who had received kidney or liver transplants, or were otherwise healthy volunteers. With the three-dose vaccination, serum antibodies were measured. RESULTS: The study included 17 transplant recipients (seven kidney and 10 liver) and 16 healthy participants. Six of seven kidney transplant recipients were on three immunosuppressive medications, whereas 9 of the 10 liver transplant recipients were on one. For the serology within 6 months from the last vaccine dose, the geometric mean titers of human papillomavirus types 6, 11, 16, and 18 were 26.7, 8.6, 35.7, and 42.4 (kidney transplant); 579.2, 569.3, 3097.3, and 835.7 (liver transplant); and 860.5, 638.8, 4391.6, and 902.6 milli-Merck Units/ml (healthy). The seropositivity rates of kidney transplant recipients for the four serotypes ranged from 50% to 75%, while all liver transplant recipients and healthy participants had 100% seropositivity rates for all four types. While there were no statistical differences of titers between liver transplant recipients and healthy participants, the titers of kidney transplant recipients were lower than those of healthy participants for type 6 (p = .034), type 11 (p = .032), and type 16 (p = .032). CONCLUSIONS: The results support the recommendation of human papillomavirus vaccination in pediatric transplant recipients given the significant risk of human papillomavirus-related diseases in this population, though immunogenicity was lower in kidney transplant recipients on multiple immunosuppressive medications.

BACKGROUND: Solid organ transplant (SOT) recipients are at increased risk of severe outcomes associated with antimicrobial resistance (AMR). Antimicrobial stewardship programs (ASPs) play a vital role in mitigating the negative impacts of AMR. Pediatric evidence regarding ASP for SOT recipients is scarce, although many pediatric SOT centers have implemented different forms of ASP. METHODS: This article summarized the available evidence relating to AMR among pediatric SOT recipients and discussed key strategies for the successful implementation of ASP among this population. The focus is primarily on antibacterial and secondarily on antifungal management. RESULTS: The development of multidisciplinary antimicrobial stewardship teams for pediatric SOT recipients is essential for successful stewardship implementation. Key stakeholders may include but are not limited to SOT recipients and their caregivers, primary SOT teams (transplant physicians, transplant pharmacists, transplant unit nurses, and transplant outpatient care team), transplant surgery teams, transplant infectious diseases teams, hospital AST, microbiology teams, infection prevention teams, quality improvement teams, and information technology teams. CONCLUSION: As the evidence for optimal ASP in pediatric SOT is still evolving, it is important to measure the impact of implemented interventions.

BACKGROUND: Approximately 25% of outpatient antibiotic prescriptions are unnecessary among family physicians in Canada. Minimizing unnecessary antibiotics is key for community antibiotic stewardship. However, unnecessary antibiotic prescribing is much harder to measure than total antibiotic prescribing. We investigated the association between total and unnecessary antibiotic use by family physicians and evaluated inter-physician variability in unnecessary antibiotic prescribing. METHODS: This was a cohort study based on electronic medical records of family physicians in Ontario, Canada, between April 2011 and March 2016. We used predefined expected antibiotic prescribing rates for 23 common primary care conditions to calculate unnecessary antibiotic prescribing rates. We used multilevel Poisson regression models to evaluate the association between total antibiotic volume (number of antibiotic prescriptions per patient visit), adjusted for multiple practice- and physician-level covariates, and unnecessary antibiotic prescribing. RESULTS: There were 499 570 physician-patient encounters resulting in 152 853 antibiotic prescriptions from 341 physicians. Substantial inter-physician variability was observed. In the fully adjusted model, we observed a significant association between total antibiotic volume and unnecessary prescribing rate (adjusted rate ratio 2.11 per 10% increase in total use; 95% CI 2.05-2.17), and none of the practice- and physician-level variables were associated with unnecessary prescribing rate. CONCLUSIONS: We demonstrated substantial inter-physician variability in unnecessary antibiotic prescribing in this cohort of family physicians. Total antibiotic use was strongly correlated with unnecessary antibiotic prescribing. Total antibiotic volume is a reasonable surrogate for unnecessary antibiotic use. These results can inform community antimicrobial stewardship efforts.

SOT recipients are more vulnerable to infections with antimicrobial-resistant organisms, and therefore, it may be useful for transplant centers to create transplant-specific antibiograms to direct empirical antimicrobial regimens and monitor trends in antimicrobial resistance. SOT-specific antibiograms were created using antimicrobial susceptibility data on isolates from 2012 to 2018 at The Hospital for Sick Children, Toronto, Ontario, Canada. The CLSI guidelines were followed to generate the antibiograms except that results from 2 years of data were pooled on a rolling basis to achieve larger sample sizes. The 3 most frequent organisms in one analysis period of the SOT antibiogram were Escherichia coli (average sample size ±standard deviation; n = 28.7 ± 3.8), Staphylococcus aureus (n = 27.8 ± 5.0), and Pseudomonas aeruginosa (non-CF) (n = 19.8 ± 8.8). For E.coli, susceptibilities in the SOT antibiogram were significantly lower than those in the hospital-wide antibiogram in 2017-2018 for ampicillin (27% vs 47%; p = .014), piperacillin/tazobactam (55% vs 88%; p < .001), cefotaxime (59% vs 89%; p < .001), ciprofloxacin (71% vs 88%; p = .007), and trimethoprim-sulfamethoxazole (41% vs 69%; p = .001), but not significantly different for aminoglycosides and meropenem. In the SOT antibiogram of E. coli, decreased susceptibility trend was confirmed in some antibiotics, including piperacillin/tazobactam (83% in 2012-2013 vs 55% in 2017-2018). At our center, the solid organ transplant-specific antibiogram revealed important differences in E. coli susceptibilities and trends in antimicrobial resistance. Developing a SOT antibiogram will assist in revising and improving empiric treatment guidelines as well as monitoring antimicrobial resistance in this population.

BACKGROUND: Evaluating the national burdens across multiple vaccine-preventable diseases (VPDs) can be informative to identify the areas for improvements in the national immunization program. METHODS: The annual burden of diseases from 2008 to 2020 in Japan were calculated with the incidence- and pathogen-based approach for the 15 VPDs (hepatitis B virus infection, human papillomavirus (HPV), influenza, invasive pneumococcal disease, invasive Haemophilus influenzae type b (Hib) disease, invasive meningococcal disease, Japanese encephalitis, measles, mumps, pertussis, rotavirus, rubella, tetanus, tuberculosis and varicella), using disability-adjusted life year (DALY). RESULTS: The average annual burden between 2008 and 2020 is the highest in influenza (114,129 DALY/year), followed by HPV infection, hepatitis B virus infection, tuberculosis and mumps (109,782, 69,883, 23,855 and 5693 DALY/year). In the pre-COVID-19 period (2008-2019), the decreasing trend of burden was observed in hepatitis B virus infection, invasive pneumococcal disease, invasive Hib disease, tuberculosis and varicella. HPV infection is the only VPD which had more than 100,000 DALY/year for all years during the study period. In 2020, the estimated annual burdens are decreased in influenza (71%), invasive pneumococcal disease (51%), invasive Hib diseases (54%), invasive meningococcal disease (64%), measles (98%), mumps (47%) pertussis (83%), rotavirus infection (95%), rubella (94%) and varicella (35%) compared with those in 2019. CONCLUSIONS: The study demonstrated decreasing trends of burdens for some VPDs, while a persistently high burden has been observed for other VPDs, including HPV infection. The COVID-19 pandemic has caused dramatic reductions in the burdens of many VPDs in 2020.

INTRODUCTION: Cytomegalovirus is the most frequently acquired congenital infectious agent that causes malformation in newborns in developed countries. Although there are many discussions worldwide about neonatal screening and treatment, there is scarce information relating to the lifetime economic burden of this disease, which is essential for calculating the cost-effectiveness of any screening and treatment programs. MATERIALS AND METHODS: Economic and lifetime health burdens of congenital cytomegalovirus infection in the Japanese annual birth cohort in 2019 were calculated, using demographic, epidemiologic, health value, and economic indicators. The economic burden was divided into medical and social costs. Sensitivity analysis was performed, using high and low values for some indicators. RESULTS: Our model estimated that the overall cost due to congenital cytomegalovirus infection in 2019 was 27.6 billion JPY. Acute care costs comprised a small portion of the medical costs. Social costs were much higher than medical costs. CONCLUSION: Our study revealed the economic burden of congenital cytomegalovirus infection in Japan, which highlighted the significance of this disease. Our study will be helpful for guiding national strategies in Japan, including neonatal screening and early treatment.

BACKGROUND: The plummeting acceptance rate of the HPV vaccine in Japan is one of the most disappointing vaccine-related events in recent times. Since 2013, the national HPV vaccine coverage rate fell from more than 70% to less than 1%. This survey investigated parental HPV vaccine acceptance and the factors that influence it. METHODS: A multi-center survey was conducted in eight hospitals in Nara prefecture, Japan, from July 2019 to March 2020. Parents were asked to answer a series of questions in a survey that included information on the HPV vaccine. RESULTS: Among the 1884 parents who answered the questionnaire, 21.8% indicated that they had accepted the HPV vaccine even before reading the information provided in the questionnaire. The overall acceptance rate after everyone had read the information increased to 50.2% (p < 0.001). Among those who still did not accept the vaccine after reading the information (N = 925), 26.7% indicated that they might change their mind if more vaccine safety reports were to appear in the mass media; other potentially influencing factors were direct communication from health care providers (35.1%), a recommendation by government (19.5%), and peer behavior (16.8%). CONCLUSION: The study showed that providing appropriate medical information significantly improves HPV vaccine acceptance. To reverse the loss of HPV vaccine acceptance in Japan, a multi-discipline approach that includes the mass media, health care providers, the government and the general population will be needed.

BACKGROUND: The human papilloma virus (HPV) vaccination coverage rate in Japan has dropped dramatically from more than 70% to less than 1% since 2013. With conflicting information and a lack of quantification of the benefits and risks of the HPV vaccine, parents have been hindered in making their decision. We quantified the benefits and risks of the HPV vaccine in terms of quality-adjusted life-years (QALYs), to help their informed decision. METHOD: A literature search was performed to determine the incidence and burden of each outcome in a decision tree model. The benefits and the risks of the HPV vaccination were determined in QALY change with a sensitivity analysis. RESULT: The benefits of the HPV vaccine in terms of QALYs gained were 703.72, 14.45, and 30.83/100,000 persons for cervical cancer, cervical intraepithelial neoplasm 3 (CIN 3), and genital warts, respectively. The QALY loss due to acute adverse reactions, chronic adverse reactions without assistance needs, and chronic adverse reactions with assistance needs were 0.07, 5.83, and 5.82/100,000 persons, respectively. The risk/benefit ratio in QALY change in the base case was 0.0156. In all scenarios, the benefit of the HPV vaccine was significantly greater than the risk. CONCLUSION: The benefits are much greater than the risks, even if it is assumed that all reported adverse events were due to the vaccination. The Japanese government and health care providers should immediately recommend the HPV vaccine to all adolescent girls irrespective of any causal links between the vaccine and reported adverse events.

BACKGROUND: Rapid molecular diagnosis of infections has contributed to timely treatments and antimicrobial stewardship. However, the benefit and cost-effectiveness vary in each country or community because they have different standard practices and health care systems. In Japan, rapid antigen tests (RATs) have been frequently used for pediatric respiratory infections. We investigated the impact and cost-effectiveness of a multiplex PCR (mPCR) respiratory panel for pediatric respiratory infections in a Japanese community hospital. METHODS: We replaced RATs with an mPCR respiratory panel (FilmArray®) for admitted pediatric respiratory infections on March 26, 2018. We compared the days of antimicrobial therapy (DOT) and length of stay (LOS) during the mPCR period (March 2018 to April 2019) with those of the RAT period (March 2012 to March 2018). RESULTS: During the RAT and mPCR periods, 1132 and 149 patients were analyzed. The DOT/case was 12.82 vs 8.56 (p < 0.001), and the LOS was 8.18 vs 6.83 days (p = 0.032) in the RAT and mPCR groups, respectively. The total costs during admissions were ∖258,824 ($2331.7) and ∖243,841 ($2196.8)/case, respectively. Pathogen detection rates were 30.2% vs 87.2% (p < 0.001). CONCLUSION: Compared to conventional RATs, the mPCR test contributed to a reduction in the DOT and LOS in a Japanese community hospital for admission-requiring pediatric respiratory infections. However, a proper stewardship program is essential to further reduce the unnecessary usage of antimicrobials.

BACKGROUND: Although tertiary hospitals have successfully introduced ASPs by antimicrobial stewardship teams, lots of community hospitals without pediatric infectious disease specialists have difficulty implementing ASP. We present a successful implementation of simple and feasible NICU antimicrobial stewardship program in a Japanese community hospital. METHOD: We developed a protocol of antimicrobial treatment in our NICU department and have implemented the protocol from September 2017. The protocol consists of start and stop of criteria antimicrobial treatment, weekend report of blood culture result from microbiology department and stopping ordering antimicrobials beforehand for the next day. We compared days of therapy (DOT) during the post-implementation period (September 2017 to August 2018) with that of pre-implementation period (March 2013 to August 2017). RESULT: In pre- and post-ASP implementation periods, 913 and 194 patients were analyzed. DOT was 175.1 and 41.6/1000 patient-days, respectively (p < 0.001) with 76.2% reduction. The percentage of neonates who had any antimicrobials and the percentage of prolonged antimicrobial treatments among neonates who had any antimicrobials decreased significantly (55.3% vs 20.6%, p < 0.001 and 65.0% vs 32.5%, p < 0.001). The protocol compliance rates were also significantly different (55.4% vs 95.4%; p < 0.001). The methicillin-resistant rate of S.aureus rates were significantly reduced in post-ASP period (31.1% vs 12.9%; p = 0.002). CONCLUSION: This ASP program was easily implemented in a NICU department of a community hospital and significantly reduced antimicrobial prescription. This kind of simple protocol may be successfully scaled-up in resource limited community hospitals without no pediatric infectious disease specialists or antimicrobial stewardship team.

BACKGROUND: C-reactive protein (CRP) has limited placental transportability. Relying on CRP level in umbilical cord blood alone is an inaccurate way to predict early onset neonatal sepsis, and we retrospectively reviewed the clinical courses of neonates with elevated CRP in umbilical cord blood. METHODS: This study was a retrospective case review of neonates with elevated CRP in umbilical cord blood (>0.5 mg/dL) in the Nara Prefecture General Medical Center, Nara, Japan between February 2013 and August 2017. We investigated the association of maternal and neonatal factors with neonatal clinical course. Then, we compared the cases of neonates with and without elevated CRP in umbilical cord blood. RESULTS: The subjects consisted of a total of 22 neonates with elevated CRP in umbilical cord blood and 344 neonates without elevated CRP in umbilical cord blood. Of the 22 neonates with elevated CRP, 18 had some symptoms of sepsis at birth, but the symptoms of 85% of the symptomatic patients resolved ≤24 h after birth. Two neonates with elevated CRP in umbilical cord blood had bacteremia, and they had poor prognoses. Elevated CRP in umbilical cord blood was associated with length of antimicrobials (P = 0.021), immature/total neutrophil ratio (P = 0.017), and pathological chorioamnionitis (CAM; P = 0.028) on multivariable logistic regression analysis. CONCLUSION: Elevated CRP in umbilical cord blood was associated with pathological CAM. Most symptoms of sepsis resolved <24 h after birth.

The mumps vaccine is not included in the national immunisation programme (NIP) of approximately 80 countries including Japan. To investigate the vaccine's cost-effectiveness, we developed a dynamic transmission model for routine one- and two-dose mumps vaccination programs in Japan. We calculated the incremental cost-effectiveness ratio compared with a current programme over a projected 50-year period. We created a Japanese population model and performed dynamic simulation to estimate the number of patients enrolled in the current programme, the routine one-dose programme, and the routine two-dose programme over the next 50 years using the Berkeley Madonna program. We estimated the medical and social costs of natural mumps infections and vaccinations to analyse cost-effectiveness. Finally, we performed a sensitivity analysis with parameters including vaccine cost, vaccine efficacy, medical costs per case, social costs per case, incidence of adverse events and discount rate. Base case analysis showed that both the one-dose and two-dose programmes predominated and that quality-adjusted life years (QALYs) were saved, compared with the current programme. The medical costs, total cost and QALYs saved during the study period in the two-dose programme compared with the current programme were 217 billion JPY, 860 billion JPY and 184 779, respectively. The two-dose programme surpassed the one-dose programme throughout the study period. In all the scenarios of the sensitivity analysis, two-dose vaccination was better than the one-dose programme. This simulation confirmed that the routine two-dose vaccination programme was more cost-effective and QALY-saving than either the one-dose programme or the current programme. Because of the variability of the results between the various models, further simulations with different models should be conducted.
RESUMO
Hepatic abscess in chronic granulomatous disease (CGD) is very refractory and frequently requires multiple surgeries with frequent morbidities. Although surgical interventions are often required, patients are often not able to have surgery for various reasons. We present the case of a 21-year-old man with recurrent hepatic abscess in CGD. We could not provide surgical interventions due to the lack of a fluid cavity and the patient's refusal, and therefore we administered transcatheter arterial antimicrobial and steroid therapy. He did not have any exacerbation for more than 18 months after the final transcatheter treatment. This is the first reported case of successful transcatheter arterial antimicrobial and steroid therapy for refractory hepatic abscess in CGD. Although the patient's burden and medical cost were not inconsequential, this case shows that the transcatheter arterial antimicrobial and steroid therapy may be a treatment option for patients who are not candidates for surgical interventions.

BACKGROUND: Admission to the neonatal intensive care unit (NICU) due to respiratory distress is determined according to subjective clinician judgement. We investigated prenatal factors predictive of NICU admission in neonates with respiratory distress. METHODS: This case-control study was conducted at Nara Prefecture General Medical Center, Nara, Japan, from February 2013 to April 2017 and included neonates with birthweight ≥2,000 g, ≥36 weeks of gestational age, who required oxygen due to respiratory distress at birth. The cases consisted of neonates admitted to the NICU, and the control group consisted of neonates who did not require NICU admission. Perinatal factors between the groups were compared, and multivariate logistic regression analysis carried out to evaluate predictive factors. RESULTS: The NICU group consisted of 94 neonates, and the control group, 417 neonates during the period reviewed. On multivariate analysis, maternal anemia (OR, 2.97; 95%CI: 1.42-6.21), infertility treatment (OR, 2.79; 95%CI: 1.36-5.71), threatened preterm labor (OR, 2.16; 95%CI: 1.10-4.23), premature rupture of membranes (OR, 5.30, 95%CI: 2.52-11.17), fibroids (OR, 6.06; 95%CI: 1.57-23.41), history of uterine surgery (OR, 3.53, 95%CI: 1.13-11.06), abruptio placentae (OR, 10.21; 95%CI: 1.83-57.17), intrauterine growth restriction (OR, 6.69; 95%CI: 1.96-22.85), and having twins (OR, 0.23; 95%CI: 0.09-0.58) were significant prenatal predictors of NICU admission. CONCLUSION: Factors that potentially predict NICU admission were identified. Clinicians may wish to consider these factors when treating neonates with respiratory distress.

BACKGROUND: Although the mumps vaccine has not been included in the national immunization program (NIP) in Japan, it has been shown that a two-dose routine vaccine program would be highly cost-effective. In this study, we carried outa questionnaire-based study to investigate how many Japanese parents want the mumps vaccine to be included in the NIP with proper information. METHODS: The questionnaire was given to parents who visited the Pediatrics or neonatal intensive care unit of Nara Prefecture General Medical Center, Nara City, Japan, between 1 March 2017 and 31 August 2017. The questionnaire consisted of information about mumps and six questions, for example (i) do parents know that mumps can be prevented by vaccine; (ii) do they know that they need to pay for mumps vaccines; and (iii) do they hope that the government will resume routine mumps vaccination. RESULTS: In total, 1,224 parents answered the questionnaire. A total of 81% and 75.4% of parents knew that mumps can be prevented by vaccination and that mumps vaccine is not included in the NIP, respectively, before reading the information. After reading the information, 95.0% of parents thought that mumps vaccine should be included in the NIP. While 61.7% of parents answered that they would choose two-dose vaccination without governmental financial support, 92.1% of them would choose two-dose vaccination with governmental financial support (P < 0.0001). CONCLUSION: Japanese parents want the mumps vaccine to be included in the NIP. Japan is able to start routine use of the mumps vaccine now.
