Abstract
BACKGROUND Kawasaki disease (KD) can result in severe coronary artery abnormalities (CAAs). Corticosteroids added to initial standard intravenous immunoglobulin (IVIG) treatment may decrease the risk for these complications. Different corticosteroid regimens (single-day high dose pulse vs multiple lower doses) may contribute to the discrepant results of prior studies. METHODS Using data from the 22nd, 23rd , and 24th Japanese nationwide KD surveys (2011-2016), we identified KD patients who did not have CAAs at first presentation and who were treated with either pulse or multiple-dose corticosteroids as part of their initial treatment. Occurrence of subsequent CAAs and treatment failure were compared between the treatment regimens and adjusted odds ratios were calculated controlling for sex, age group, illness day at first treatment, survey, and recurrent KD. RESULTS There were 782 KD patients who received pulse corticosteroid treatment and 4,817 who received multiple dose treatment. Patients receiving multiple dose treatment were less likely to develop CAAs (5.5% vs 8.3%, OR 0.64; 95% CI: 0.48-0.85) or treatment failure (21.4% vs 41.6%; OR: 0.38; 95% CI: 0.33-0.45). Adjusted analyses showed similar protective effects of multiple-dose treatment against CAAs (OR: 0.67, 95% CI: 0.51-0.90) and treatment failure (OR: 0.39, 95% CI: 0.33-0.46). CONCLUSIONS Multiple-dose corticosteroid combination treatment resulted in substantially improved outcomes in KD patients compared to pulse treatment. For patients who may be at elevated risk of treatment failure or CAA, use of multiple-dose corticosteroids in conjunction with IVIG is likely to provide considerable clinical benefit.

Abstract
BACKGROUND The long-term prognosis of those with a history of Kawasaki disease (KD) is still unknown. METHODS Using a permanent registry system in Japan (koseki), 6,576 persons with a history of KD were followed up. The average follow-up period was 30 years. The endpoint was death. RESULTS With a 99.5% follow-up rate, 68 deaths (48 males and 20 females) were observed. The overall standardized mortality ratio, of which reference was vital statistics in Japan, was not elevated. However, the observation according to the presence or absence of cardiac sequelae showed that the standardized mortality ratio for those with cardiac sequelae significantly elevated. Nine persons, all of whom were males, died of KD (including those cases where KD was suspected), but all deaths occurred in individuals who were under 30 years of age. CONCLUSIONS This study revealed the long-term prognosis for KD, but almost all participants were younger than 40 years. Continuing follow up of this cohort is required to clarify whether a history of KD relates to the development of atherosclerosis when participants become middle aged or older.

Abstract
OBJECTIVES Smoking is a risk factor for stroke. The relationship between smoking and the risk of different subtypes of stroke has not been fully elucidated. We investigated the relationship between smoking and the incidence of stroke in the Japanese population. MATERIALS AND METHODS This prospective, population-based cohort study included 11,324 participants (4447 men; 6877 women) from 12 districts in Japan, between April 1992 and July 1995. Participants were stratified according to smoking status (non-smoker [never smoked]/ex-smoker/current smoker). Male current smokers were further stratified according to the number of cigarettes smoked per day (1-14, 15-29, or ≥ 30). The non-smoking group was used as a reference. Cox proportional hazards analysis was used to determine the risk of stroke due to smoking. RESULTS Four hundred and seventeen new stroke events (212 men; 205 women) were recorded during a mean follow-up of 10.7 years, including 95 intracerebral hemorrhages (48 men; 47 women), 267 cerebral infarctions (152 men; 115 women), and 54 subarachnoid hemorrhages (12 men; 42 women). In multivariable analysis, the hazard ratios (95% confidence intervals) for male current smokers (≥ 30 cigarettes/day) were 1.89 (1.08-3.31) and 3.41 (1.22-9.57) for all strokes and intracerebral hemorrhages, respectively; those for female current smokers were 2.78 (1.62-4.74), 3.14 (1.51-6.54), and 4.03 (1.64-9.93) for all strokes, cerebral infarctions, and subarachnoid hemorrhages, respectively. CONCLUSIONS Smoking ≥ 30 cigarettes/day is a risk factor for stroke, especially intracerebral hemorrhage in men. Furthermore, smoking increases the risk of cerebral infarction and subarachnoid hemorrhage in women.

Abstract
OBJECTIVE To assess the epidemiologic association between Kawasaki disease and common pediatric infectious diseases (PIDs) identified during the coronavirus disease 2019 (COVID-19) pandemic period to confirm whether the infection-triggered theory is a plausible hypothesis for the pathogenesis of Kawasaki disease. STUDY DESIGN A retrospective epidemiologic study was conducted using datasets obtained from Web-based surveillance of Kawasaki disease and PIDs in Japan. We compared weekly numbers of patients who developed Kawasaki disease and specific PIDs between 2020 and 2017-2019 and evaluated the association between the percent reduction in the number of patients with these diseases. RESULTS A total of 868 patients developed Kawasaki disease in 2020. During the social distancing period in 2020, the number of patients with Kawasaki disease was approximately 35% lower than in 2017-2019. Time from the onset of Kawasaki disease until the first hospital visit did not differ significantly among the examined years. The proportion of older children with Kawasaki disease decreased more than that of infants with Kawasaki disease (age <1 year), resulting in a significant difference in the proportion of infant patients between 2020 and 2017-2019 (24% vs 19%; P < .01). The number of patients with incomplete Kawasaki disease was unchanged from that of previous years. The weekly percent reduction in patient numbers differed between Kawasaki disease and PIDs during 2020, with no strong correlation between the 2 diseases. CONCLUSIONS Our data indicate that parents of patients with Kawasaki disease did not avoid hospital visits during the COVID-19 pandemic period. The findings indicate the possibility that triggering Kawasaki disease might be associated with presently unidentified respiratory pathogen(s) that potentially might be acquired from both within and outside the household.

Abstract
Background Anti-programmed cell death protein 1 (PD-1) antibody monotherapy (PD1) has led to favorable responses in advanced non-acral cutaneous melanoma among Caucasian populations; however, recent studies suggest that this therapy has limited efficacy in mucosal melanoma (MCM). Thus, advanced MCM patients are candidates for PD1 plus anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) combination therapy (PD1 + CTLA4). Data on the efficacy of immunotherapy in MCM, however, are limited. We aimed to compare the efficacies of PD1 and PD1 + CTLA4 in Japanese advanced MCM patients. Patients and methods We retrospectively assessed advanced MCM patients treated with PD1 or PD1 + CTLA4 at 24 Japanese institutions. Patient baseline characteristics, clinical responses (RECIST), progression-free survival (PFS), and overall survival (OS) were estimated using Kaplan–Meier analysis, and toxicity was assessed to estimate the efficacy and safety of PD1 and PD1 + CTLA4. Results Altogether, 329 patients with advanced MCM were included in this study. PD1 and PD1 + CTLA4 were used in 263 and 66 patients, respectively. Baseline characteristics were similar between both treatment groups, except for age (median age 71 versus 65 years; P < 0.001). No significant differences were observed between the PD1 and PD1 + CTLA4 groups with respect to objective response rate (26% versus 29%; P = 0.26) or PFS and OS (median PFS 5.9 months versus 6.8 months; P = 0.55, median OS 20.4 months versus 20.1 months; P = 0.55). Cox multivariate survival analysis revealed that PD1 + CTLA4 did not prolong PFS and OS (PFS: hazard ratio 0.83, 95% confidence interval 0.58-1.19, P = 0.30; OS: HR 0.89, 95% confidence interval 0.57-1.38, P = 0.59). The rate of ≥grade 3 immune-related adverse events was higher in the PD1 + CTLA4 group than in the PD1 group (53% versus 17%; P < 0.001). Conclusions First-line PD1 + CTLA4 demonstrated comparable clinical efficacy to PD1 in Japanese MCM patients, but with a higher rate of immune-related adverse events. Anti-PD-1 plus anti-CTLA-4 antibody therapy (PD1 + CTLA4) is an option for patients with advanced mucosal melanoma (MCM). Data on the efficacy of PD1 + CTLA4 compared with PD-1 monotherapy (PD1) for MCM, however, are limited. We retrospectively analyzed data from 329 Japanese patients with advanced MCM treated with PD1 or PD1 + CTLA4. No significant differences in objective response rate, progression-free survival, or overall survival were observed. Immune-related adverse events resulting in treatment cessation were higher in the PD1 + CTLA4 group.

Abstract
OBJECTIVE We previously established a descriptive dietary record method that accurately quantifies habitual water intake from food and beverages, to ascertain the relationship between water intake and health. Here, we verified the validity of a selective recall method, which is easy for users to answer and analyze. PATIENTS AND METHODS Japanese men and women aged 20-44 years (n = 16) and 45-64 years (n = 16) participated over three working days and one non-working day. The day following each of the surveyed days, participants collected their first morning urine for urinalysis and completed a selective recall and descriptive dietary record questionnaire. RESULTS The two methods of determining water intake were positively correlated (r = 0.94, p < 0.0001). Water intake volumes from non-alcoholic beverages (r = 0.94, p < 0.0001), alcoholic beverages (r = 1.00, p < 0.0001), and food (r = 0.72, p < 0.0001), calculated using the two methods, exhibited strong correlation. No correlation was observed between urinalysis parameters and total water intake. A significant, negative correlation was observed between urine osmolarity and total water intake in men (r = -0.55, p = 0.0011) and women (r = -0.51, p = 0.0032) aged 20-44 years. CONCLUSIONS Selective recall is a valid method for assessing water intake from food and beverages.

Abstract
OBJECTIVE This nationwide study aimed to reveal the prevalence of ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-ax SpA), and the positive rate of human leukocyte antigen (HLA) among these patients in Japan. METHODS The first survey was conducted in 2221 randomly selected facilities (26.3%) in September, 2018, where the patients with AS/nr-ax SpA were taken care of from January to December, 2017. We estimated the total number of these patients using response and extraction rate. A second survey was conducted in 117 facilities (49.8%) to assess for HLA-B 27 positivity rate and clinical features. RESULTS The estimated total number of the patients with AS and nr-ax SpA were 3200 (95% confidence interval [CI]: 2400-3900) and 800 (530-1100), suggesting that the prevalence of AS and nr-ax SpA in general population were 2.6/100,000 (0.0026%) and 0.6/100,000 (0.0006%), respectively. Although 55.5 % (76/137) of patients with AS were HLA-B27 positive, those whose age of onset was estimated to be over 50 years tended to undergo less HLA-B27 testing. CONCLUSION This study revealed the lower prevalence of AS/nr-ax SpA in Japan, compared to those in other countries. Further studies are required to reveal the association of HLA-B27 with the clinical features.

Abstract
Abstract
Background
The secretion of brain natriuretic peptide (BNP) by left ventricular (LV) myocytes increases even in patients with normal LV function. Currently, the cause of BNP increase in patients with stages A and B chronic heart failure remains unknown.
Purpose
To investigate the increase of BNP in early-stage, asymptomatic heart failure.
Methods
Consecutive patients (N=188; mean age: 68±11 years; body mass index: 23.0±3.9 kg/m2, female/male: 88/100) with heart failure (stages A and B), including non-valvular atrial fibrillation (NVAF), and LV ejection fraction >50% with estimated glomerular filtration rate >30% were recruited in this study. The echocardiographic parameters of LV systolic function (e.g., LV endo-diastolic/endo-systolic volume and ejection fraction) or diastolic markers (e.g., E/A ratio calculated from the trans mitral flow velocity and E/e' ratio), in addition to the data obtained from tissue Doppler images, were evaluated. LA volume was obtained from a three-dimensional heart model. Moreover, LV and left atrial (LA) global longitudinal strains were evaluated. The BNP levels measured within 1 month from echocardiographic examination were compared with the echocardiographic markers, in addition to an estimated glomerular filtration rate.
Results
BNP was elevated in patients with NVAF (NVAF, median: 63.0 pg/ml [quartile: 33.2–74.7 pg/ml]; non-NVAF, median: 25.6 pg/ml [quartile: 13.5–50.8 pg/ml]; p=0.0015) and patients with stage B heart failure (stage B, median: 41.7 pg/ml [quartile: 21.5–67.5 pg/ml]; stage A, median: 23.4 pg/ml [quartile: 11.7–39.0 pg/ml]; p=2.99E-05). The presence of hypertension and the sex of patients did not lead to significant differences in this population. The LA volume corrected by the body surface area was well correlated with the BNP value (r=0.55; 95% confidence interval [CI]: 0.44–0.64; p=4.42E-16) and age (r=0.51; 95% CI: 0.40–0.61; p=4.64E-14). LA global longitudinal strain (r=−0.42; 95% CI: −0.53 to −0.29; p=3.05E-09) and the velocity of interventricular septum during atrial contraction (r=−0.40; 95% CI: −0.51 to −0.27; p=1.84E-08) were also correlated with BNP elevation. However, the markers of diastolic and systolic function of LV were not correlated with BNP increase in patients with subclinical heart failure. Multivariate analysis revealed that LA volume (β: 0.991; 95% CI: 0.682–1.299; p=1.85E-09), stage B heart failure (β: 0.116; 95% CI: 0.016–0.216; p=0.023), age (β: 0.013; 95% CI: 0.008–0.018; p=6.414E-07), body mass index (β: −0.020; 95% CI: −0.033 to 0.007; p=0.002), and a decrease in the velocity of interventricular septum during atrial contraction (β: −0.048; 95% CI: −0.070 to −0.026; p=2.683E-05) contributed to the increase in BNP.
Conclusion
LA enlargement with no relation to diastolic function, age, and diminishment of interventricular motion caused by atrial contraction may be sensitive markers of BNP secretion in patients with subclinical stage, asymptomatic heart failure.

Abstract
Abstract
Background
Ankylosing spondylitis (AS) causes severe chronic inflammation of the spine and sacroiliac joints, leading to severe physical dysfunctions. Non-radiographic axial spondyloarthritis (nr-ax SpA) is a newly categorized disease in SpA that shows SpA without definite radiographic findings in sacroiliac joint. Although human leukocyte antigen (HLA) positivity is related to these diseases, little is known about the prevalence of these diseases and HLA-B27 positivity in Japan.
Methods
A nationwide survey was conducted from January to December 2017. 2221/8456 facilities (26.3%) were selected randomly as a target sample, comprising all three departments: orthopedics, pediatrics, and rheumatology. We estimated the number of these patients by using response and extraction rate, and calculated the HLA-B27 positivity rate.
Results
We estimated the prevalence of AS and nr-ax SpA as 2.6/100,000 (0.0026%) and 0.6/100,000 (0.0006%), respectively. HLA-B27 test was performed in 60% of patients with AS, of which 55.5% being HLA-B27 positive; however, they were less likely to receive HLA-B27 test if their estimated age of onset was over 50 years.
Conclusions
The prevalence in AS and nr-ax SpA and their HLA-B27 positivity rate in Japan were lower compared to other countries. Further studies will be required to reveal the association between HLA-B27 and the clinical features.
Key messages
The prevalence of AS and nr-ax SpA in Japan are estimated to be 2.6/100,000 (0.0026%) and 0.6/100,000 (0.0006%), respectively, and are lower than those in other countries. In addition, HLA-B27 positivity rate was lower.

Abstract
Abstract
Background
Kawasaki disease (KD) is the most common cause of acquired pediatric heart disease in developed countries. The study aimed to summarize the epidemiologic characteristics, treatments, and cardiac complications of KD, using data from the nationwide survey in Japan.
Methods
The nationwide survey in Japan has been conducted biennially since 1970. The survey respondents were hospitals specializing in pediatrics and those with ≥100 beds and a pediatric department throughout Japan, where KD patients were eventually hospitalized. The most recent survey was completed in 2019, obtaining information for patients who developed KD during 2017–2018.
Results
The survey identified 32528 KD patients, which comprised 15164 (47%) in 2017 and 17364 (53%) in 2018. The highest annual incidence rate was recorded in 2018 (359 per 100,000 children aged 0–4 years). After 1982, patients with ≤4 principal KD signs increased, resulting in 6847 (21%) patients diagnosed during 2017–2018. Among 30784 patients who received initial intravenous immunoglobulin administration, 6061 (20%) did not respond. Within 30 days of KD onset, 9.0% of patients were diagnosed with cardiac complications, and consequently, 2.6% of patients developed cardiac sequelae after the acute illness.
Conclusions
The annual number of patients developing KD in Japan increased from 1970 through 2018, while the proportion of KD patients with cardiac complications decreased. Recent advances in KD treatments might have contributed to preventing the development of cardiac complications.
Key messages
We analyzed large-scale data and summarized the epidemiologic characteristics, treatments, and cardiac complications of KD in Japan.

Serum sodium level associated with coronary artery lesions in patients with Kawasaki disease. Clin Rheumatol 2021; 41:137-145. [PMID: 34363547 DOI: 10.1007/s10067-021-05881-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 07/23/2021] [Accepted: 08/02/2021] [Indexed: 12/23/2022]
Abstract
INTRODUCTION/OBJECTIVES Hyponatremia is a potential risk factor for the development of coronary artery lesions (CALs) identified after acute Kawasaki disease (KD). However, the serum sodium distribution corresponding to the reference intervals differs between infants (< 1 year of age) and older children. We hypothesized the association of serum sodium level with CAL complications differs between infants and older patients with KD. METHODS We analyzed 21,610 population-based patients who developed KD throughout Japan during 2013-2014. We performed multivariable logistic regression analyses to evaluate the association between serum sodium and CAL complications. Additionally, we stratified the serum sodium distribution associated with CAL complications by infants and older patients. RESULTS CALs were identified in 158 (3.6%) infants and 302 (1.8%) older patients. Infants were more likely to develop CALs when within the normal sodium range compared with older patients (75% vs. 29%), whereas most older patients developed CALs with a sodium level lower than the reference interval. Serum sodium ≤ 130 mEq/L indicated significantly higher risk for development of CALs in both groups (adjusted odds ratio [95% confidence intervals] = 3.21 [1.65-6.25] in infants and 1.74 [1.18-2.57] in older patients). CONCLUSIONS Serum sodium distribution associated with CAL complications differed greatly between infants and older patients. Older patients developed CALs with sodium levels lower than the reference interval; however, among infants, hyponatremia was not necessarily a risk factor for developing coronary artery lesion. When considering risk assessments for CALs using serum sodium levels, infants with KD should be distinguished from older patients. Key Points • Hyponatremia is a potential risk factor for the development of coronary artery lesions (CALs) among patients with Kawasaki disease. • However, the serum sodium distribution corresponding to the reference intervals differs between infants (< 1 year of age) and older children. • Most infants developed CALs within the normal sodium range, whereas older patients developed at a range lower than the reference interval. • These findings highlight that when considering risk assessments for CALs using serum sodium levels, infants should be distinguished from older patients.

Abstract
The causal effects of vaccines on Kawasaki disease (KD) remain elusive. We aimed to examine the association between vaccines administered during infancy and the development of KD in Japan. We conducted a multicenter prospective case-control study using questionnaires and compared the vaccination status of infants (age: 6 weeks to 9 months) who developed KD (KD group; n = 102) and those who did not develop KD (non-KD group; n = 139). Next, we performed a case-crossover study of 98 cases in the KD group and compared the status of vaccinations between the case and control periods. We also compared the incidence of KD in children for each 5-year period before and after the addition of new vaccines (2012–2013) using data from the Nationwide Survey of KD. In the case-control study, the vaccination status of the KD and control groups did not differ to a statistically significant extent. Multivariable analysis of the vaccination status and patient backgrounds showed no significant association between vaccination and KD development. In the case-crossover study, the status of vaccinations during the case and control periods did not differ to a statistically significant extent. In the analysis of data from the Nationwide Survey of KD, the incidence of KD in children of ages subject to frequent vaccination showed no significant increases in the latter five years, 2014–2018. Based on these prospective analyses, we confirmed that vaccination in early infancy did not affect the risk of KD.

Abstract
We report observations of gamma-ray emissions with energies in the 100-TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directions of the Cygnus OB1 and OB2 associations. Based on their positional coincidences, we associate one with a pulsar PSR J2032+4127 and the other mainly with a pulsar wind nebula PWN G75.2+0.1, with the pulsar moving away from its original birthplace situated around the centroid of the observed gamma-ray emission. This work would stimulate further studies of particle acceleration mechanisms at these gamma-ray sources.

Abstract
BACKGROUND Lower socioeconomic status (SES) may be related to inactivity lifestyle; however, the association between SES and physical inactivity has not been sufficiently investigated in Japan. METHODS The study population is the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2,609 adults. Physical activity was assessed by physical activity index (PAI) calculated from activity intensity and time. The lowest tertile of PAI for each 10-year age class and sex was defined as physical inactivity. Multivariable logistic regression analyses were conducted to examine the association of SES (employment status, educational attainment, living status, and equivalent household expenditure (EHE)) with physical inactivity. RESULTS In the distribution of PAI by age classes and sex, the highest median PAI was aged 30-39 years among men (median 38.6), aged 40-49 years among women (38.0), and median PAI was decreased with increasing age. Multivariable-adjusted model shows that not working was significantly associated with physical inactivity after adjustment for age in all age groups and sexes. Not living with spouse for adult women and elderly men was significantly associated with physical inactivity compared to those who living with spouse. However, neither educational attainment nor EHE had any significant associations with physical inactivity. CONCLUSIONS The result indicated that physical inactivity was associated with SES in a general Japanese population. SES of individuals need to be considered in order to prevent inactivity lifestyle.

Abstract
OBJECTIVE To investigate whether redness and crusting at the bacille Calmette-Guérin inoculation site (BCGitis), identified during acute illness owing to Kawasaki disease (KD), is an independent risk factor for development of cardiac complications. DESIGN Retrospective cohort study using data from the nationwide KD survey in Japan. SETTING Survey respondents included hospitals specialising in paediatrics and hospitals with ≥100 beds and a paediatric department throughout Japan. PATIENTS We included 17 181 patients with KD across Japan during 2005-2006. MAIN OUTCOME MEASURES BCGitis and cardiac complications resulting from KD. RESULTS BCGitis was identified in 7549 (44%) patients with KD. Compared with patients without BCGitis, those with BCGitis were younger, more likely to be male, less likely to have recurrent status and visited a hospital and underwent initial intravenous immunoglobulin (IVIG) treatment earlier after KD onset. In the unadjusted model, patients with BCGitis were significantly less likely to have cardiac complications (crude OR 0.81, 95% CI 0.71 to 0.92). However, after including treatment factors (days of illness at initial IVIG and treatment responsiveness) in the adjusted model, the association was no longer significant (adjusted OR 0.89, 95% CI 0.77 to 1.03), indicating that BCGitis was not an independent factor associated with cardiac complication and might be confounded by treatment factors. CONCLUSIONS BCGitis was identified in comparatively early illness stages of KD. Our findings indicated that BCGitis was not an independent factor associated with developing cardiac complications but was confounded by prompt initial IVIG administration, which might result in successful treatment and prevention of cardiac complications.

Abstract
We previously reported a phenotype of Creutzfeldt-Jakob disease (CJD), CJD-MMiK, that could help identify iatrogenic CJD. To find cases mimicking CJD-MMiK, we investigated clinical features and pathology of 1,155 patients with diagnosed sporadic CJD or unclassified CJD with and without history of neurosurgery. Patients with history of neurosurgery more frequently had an absence of periodic sharp-wave complexes on electroencephalogram than patients without a history of neurosurgery. Among 27 patients with history of neurosurgery, 5 had no periodic sharp-wave complexes on electroencephalogram. We confirmed 1 case of CJD-MMiK and suspected another. Both had methionine homozygosity at codon 129 of the prion protein gene and hyperintensity lesions in the thalamus on magnetic resonance images of the brain, which might be a clinical marker of CJD-MMiK. A subgroup with a history of neurosurgery and clinical features mimicking dura mater graft-associated CJD might have been infected during neurosurgery and had symptoms develop after many years.
