BACKGROUND: The sarcoidosis mortality rate has increased over the years, which contributes to the health care burden. Although epidemiological studies of sarcoidosis mortality in aging societies are essential, none have been published since 1989 in Japan. METHODS: We aimed to investigate the trends in crude and age-adjusted sarcoidosis-associated mortality rates per 1,000,000 population in Japan from 2001 to 2020 using national death certificate data among older adults aged over 50 years. The data were analysed using the joinpoint regression models to estimate long-term trends and average annual percentage changes (AAPCs). RESULTS: A total of 3094 sarcoidosis-associated deaths were recorded from 2001 to 2020 in Japan; women constituted 65.3% of these, with a female:male ratio of 1.89. Nearly 80% of deaths were over the age of 65 years, of which 32% were over the age of 80 years. The trend in crude mortality of those aged ≥80 years markedly increased from 0.81 to 9.68 per 1,000,000 population in men and from 2.38 to 12.87 in women, respectively. The overall age-adjusted sarcoidosis mortality rate increased 2.46-fold during the study period, with an AAPC of 5.1%. CONCLUSIONS: This study revealed that sarcoidosis-associated deaths in Japan have significantly increased over the past two decades, especially among the older population with a female predominance. Given the rising mortality rate and susceptibility of the older population, sarcoidosis will require more attention from health care providers in terms of a multidisciplinary approach to address the specific needs of the older population.

To investigate adverse reactions and attitudes toward the vaccine during the first month after mRNA- 1273 vaccination in a larger sample including younger men and women in Japan, we distributed a 1-month post-vaccination questionnaire using a Google form to 8,566 people who received a second dose of mRNA-1273 at Okayama University. The response rate was about 40.2% (3,447 responses), the sex ratio was about the same, and 73.3 % (2,528 respondents) were students in their twenties or younger. Poisson regression with robust variance was performed to calculate the prevalence ratio of each symptom by different attributes. The most common adverse reactions after the second vaccine dose were local pain (80.4%), fever (85.1%), malaise (82.0%), headache (64.0%), and chills (57.4%). Approximately 99% of respondents reported that their adverse reactions resolved within 1 week. Over 80% of respondents were satisfied with their vaccination (87.2%), expressed interest in receiving the third vaccination (83.3%), and would recommend vaccination to their loved ones (80.2%). However, among them, 22.0% (757 respondents) would recommend and 28.4% (980 respondents) also stated that they would consider the type of vaccine in these decisions.

Symptoms of long COVID are complex and long-lasting, and endocrine dysfunction might be involved in the underlying mechanisms. In this study, to clarify the hormonal characteristics of long COVID patients, laboratory data for patients who visited the outpatient clinic for long COVID were evaluated. A retrospective analysis was performed for patients who visited Okayama University Hospital during the period from Feb 2021 to Dec 2021 with focus on the interrelationships between major symptoms and endocrine data. Information and laboratory data were obtained from medical records for 186 patients. The patients had various symptoms, and the most frequent symptoms were general malaise, dysosmia/dysgeusia, hair loss, headache, dyspnea, and sleeplessness. Patients who were suffering from fatigue and dysosmia/dysgeusia were younger, while hair loss was more frequent in older and female patients. As for the characteristics of patients suffering from general fatigue, the scores of depression and fatigue were positively correlated with serum levels of cortisol and free thyroxin (FT4), respectively. Also, patients suffering from general fatigue had lower levels of serum growth hormone and higher levels of serum FT4, while patients with dysosmia/dysgeusia had a significantly lower level of serum cortisol. Serum thyrotropin (TSH) levels were higher and the ratios of FT4/TSH were lower in the initially severe cases, suggesting occult hypothyroidism. In addition, the ratios of plasma adrenocorticotropin to serum cortisol were decreased in patients with relatively high titers of serum SARS-CoV-2 antibody. Thus, hormonal changes seem to be, at least in part, involved in the persistent symptoms of long COVID.

After the acute phase of COVID-19, some patients have been reported to have persistent symptoms including general fatigue. We have established a COVID-19 aftercare clinic (CAC) to provide care for an increasing number of these patients. Here, we report the case of a 36-year-old man who developed post-COVID fatigue after acute infection with SARS-CoV-2. In the acute phase of COVID-19, the patient's fever resolved within four days; however, general fatigue persisted for three months, and he visited our CAC 99 days after the initial infection. Examination revealed a high Aging Male's Symptoms (AMS) score of 44 and low free testosterone (FT) level of 5.5 pg/mL, which meet the Japanese criteria of late-onset hypogonadism (LOH) syndrome. Imaging studies revealed an atrophic pituitary in addition to fatty liver and low bone mineral density. Anterior pituitary function tests showed a low follicle-stimulating hormonelevel and delayed reaction of luteinizing hormone (LH) after gonadotropin-releasing hormone (GnRH) stimulation, indicating the possibility of hypothalamic hypogonadism in addition to primary hypogonadism seen in patients with post-COVID-19 conditions. After the initiation of Japanese traditional medicine (Kampo medicine: hochuekkito followed by juzentaihoto), the patient's symptoms as well as his AMS score and serum FT level were noticeably improved. Furthermore, follow-up tests of GnRH stimulation revealed improvements in LH responsiveness. Although many patients have been reported to meet the criteria of ME/CFS such as our case, we emphasize the possibility of other underlying pathologies including LOH syndrome. In conclusion, LOH syndrome should be considered a cause of general fatigue in patients with post-COVID-19 conditions and herbal treatment might be effective for long COVID symptoms due to LOH (264 words).

To promote antimicrobial stewardship, we studied antimicrobial prescription rates for uncomplicated cystitis, a common outpatient disease requiring antibiotic treatment. This multicenter retrospective study was performed from January 1, 2018, to December 31, 2020, in Japan, targeting outpatients aged ≥ 20 years whose medical records revealed International Classification of Diseases (ICD-10) codes suggesting uncomplicated cystitis (N300). The data of 1445 patients were collected and that of 902 patients were analyzed. The overall median patient age was 71 years and a proportion of those aged less than 50 years was 18.8% with a female dominance (82.6%). Antimicrobials were prescribed for 884 patients (98.0%) and a total of 623 patients (69.1%) were treated with broad-spectrum drugs, including fluoroquinolones (36.0%), third-generation cephalosporins (29.9%) and faropenem (3.1%). A logistic regression model revealed that the broad-spectrum agents were significantly prescribed for the older patients, male patients, and those who visited internists. Recurrence was observed in 37 (4.1%) cases, and the multivariate analysis suggested any of age, sex, or antimicrobial types were not associated with the recurrence. Collectively, approximately two-thirds of antimicrobials prescribed for uncomplicated cystitis were broad-spectrum agents. The present data would be an indicator for antimicrobial prescriptions in uncomplicated cystitis in Japan.

The pathogenesis and prognosis of post COVID-19 condition have remained unclear. We set up an outpatient clinic specializing in long COVID in February 2021 and we have been investigating post COVID-19 condition. Based on the results of our earlier study showing that "general fatigue" mimicking myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is the most common symptom in long COVID patients, a retrospective analysis was performed for 39 male patients in whom serum free testosterone (FT) levels were measured out of 61 male patients who visited our clinic. We analyzed the medical records of the patients' backgrounds, symptoms and laboratory results. Among the 39 patients, 19 patients (48.7%) met the criteria for late-onset hypogonadism (LOH; FT < 8.5 pg/mL: LOH group) and 14 patients were under 50 years of age. A weak negative correlation was found between age and serum FT level (r = -0.301, p = 0.0624). Symptoms including general fatigue, anxiety, cough and hair loss were more frequent in the LOH group than in the non-LOH group (FT ≥ 8.5 pg/mL). Among various laboratory parameters, blood hemoglobin level was slightly, but significantly, lower in the LOH group. Serum level of FT was positively correlated with the levels of blood hemoglobin and serum total protein and albumin in the total population, whereas these interrelationships were blurred in the LOH group. Collectively, the results indicate that the incidence of LOH is relatively high in male patients, even young male patients, with post COVID-19 and that serum FT measurement is useful for revealing occult LOH status in patients with long COVID.

AIM: Despite the increasing attention that has been paid to amyloidosis in recent years, there have been few reports on amyloidosis mortality and its trends worldwide. This study aimed to evaluate the trends in crude and age-adjusted amyloidosis-associated mortality rates in Japan from 1998 to 2019. METHODS: We used national Vital Statistics data among older adults aged over 50 years. The data were analyzed using the joinpoint regression program to estimate the long-term trends and average annual percentage changes (AAPCs). RESULTS: A total of 9158 amyloidosis-associated deaths were recorded from 1998 to 2019, of which 56.1% were in men. The crude mortality rate per 1 000 000 older adults aged over 80 years increased from 9.65 to 54.3 among men and from 7.02 to 22.1 among women during the study period. Overall, the AAPCs of age-adjusted amyloidosis-associated mortality rates increased significantly over the study period (1.8%, 95% confidence interval [CI], 1.0-2.7%). While the annual percentage change (APC) of age-adjusted mortality rates in women showed no significant change over the study period, the APC in men markedly increased in the 2013-2019 period (8.2%, 95% CI: 6.0-10.4%). CONCLUSIONS: This study revealed an increasing trend in mortality associated with amyloidosis, and in particular a marked increase in mortality among men over the past 6 years. Considering its high mortality rate and susceptibility to the effects of an increasing population of older adults, amyloidosis deserves more attention from healthcare providers to improve the understanding of diagnosis, clinical treatment, and healthcare planning.

BACKGROUND: Various symptoms persist even after the acute symptoms in about one third of patients with COVID-19. In February 2021, we established an outpatient clinic in a university hospital for patients with long COVID and started medical treatment for sequelae that persisted one month or more after infection. METHODS: To determine the key factors that affect the onset and clinical course of sequelae, a retrospective analysis was performed at Okayama University Hospital (Japan) between February and July 2021. We focused on changes in the numbers of symptoms and the background of the patients during a three-month period from the first outpatient visit. We also examined the relationship with SARS-CoV-2 antibody titers. RESULTS: Information was obtained from medical records for 65 patients. The symptoms of sequelae were diverse, with more than 20 types. The most frequent symptoms were general malaise, dysosmia, dysgeusia, sleeplessness, and headache. These symptoms improved in about 60% of the patients after 3 months. Patients who required hospitalization and had a poor condition in the acute phase and patients who received oxygen/dexamethasone therapy had higher antibody titers at the time of consultation. Patients with antibody titers ≥200 U/mL showed significantly fewer improvements in long COVID symptoms in 1 month, but they showed improvements at 3 months after the first visit. CONCLUSION: Long COVID symptoms were improved at 3 months after the initial visit in more than half of the patients. Serum antibody titers were higher in patients who experienced a severe acute phase, but the serum antibody titers did not seem to be directly related to the long-term persistence of long COVID symptoms.

記述言語：英語掲載種別：研究論文（学術雑誌）

BACKGROUND: We analyzed data from COVID-19 patients in Japan to assess the utility of the 4C mortality score as compared with conventional scorings. METHODS: In this multicenter study, COVID-19 patients hospitalized between March 2020 and June 2021, over 16 years old, were recruited. The superiority for correctly predicting mortality and severity by applying the receiver operating characteristic (ROC) curve was compared. A Cox regression model was used to compare the length of hospitalization for each risk group of 4C mortality score. RESULTS: Among 206 patients, 21 patients died. The area under the curve (AUC) (95% confidential interval (CI)) of the ROC curve for mortality and severity, respectively, of 4C mortality scores (0.84 (95% CI 0.76-0.92) and 0.85 (95% CI 0.80-0.91)) were higher than those of qSOFA (0.66 (95% CI 0.53-0.78) and 0.67 (95% CI 0.59-0.75)), SOFA (0.70 (95% CI 0.55-0.84) and 0.81 (95% CI 0.74-0.89)), A-DROP (0.78 (95% CI 0.69-0.88) and 0.81 (95% CI 0.74-0.88)), and CURB-65 (0.82 (95% CI 0.74-0.90) and 0.82 (95% CI 0.76-0.88)). For length of hospitalization among survivors, the intermediate- and high- or very high-risk groups had significantly lower hazard ratios, i.e., 0.48 (95% CI 0.30-0.76)) and 0.23 (95% CI 0.13-0.43) for discharge. CONCLUSIONS: The 4C mortality score is better for estimating mortality and severity in COVID-19 Japanese patients than other scoring systems.

記述言語：英語

Coronavirus disease 2019 (COVID-19) has been spreading worldwide with unprecedented rapidity. Staphylococcus aureus is reported to frequently cause bacterial complications in patients with COVID-19. We herein present two additional cases of S. aureus pneumonia involving such patients. The first case was an obese 48-year-old man without any particular underlying diseases. The second case was another patient, a 72-year-old man, with hypertension, dyslipidemia, and steatohepatitis. Both patients developed methicillin-susceptible S. aureus pneumonia in the clinical course of COVID-19, to which antibiotic therapy with cefazolin was effectively administered. Through these cases, we emphasize that S. aureus secondary infections should be well cared with a high degree of caution in a case of critically ill COVID-19 patients.

Subclinical hypothyroidism (SCH) is diagnosed when serum thyrotropin (TSH) is elevated despite a normal thyroxine level and is known to increase the risk of metabolic disorders. This study was conducted to identify potential laboratory markers suspicious for latent SCH. We retrospectively reviewed 958 outpatients in whom thyroid functions had been examined. Eighty-five (9.1%) of the 939 analyzed subjects had SCH (73% females). In the SCH group, median serum TSH and FT4 levels were 5.04 μU/ml and 1.19 ng/dl, respectively, and auto-thyroid antibodies were detected in 53.8% of patients. SCH group patients were significantly older than patients in the euthyroid group, while there was no intergroup difference in BMI. However, 56.5% of the SCH patients were asymptomatic. In the SCH group, serum aspartate aminotransferase and low-density lipoprotein cholesterol (LDL-C) levels were significantly higher, and the estimated glomerular filtration rate (eGFR) was significantly lower than in the euthyroid group. Among patients less than 65 years of age, SCH patients tended to have lower eGFR and higher LDL-C than euthyroid patients. Age-dependent reductions of red blood cells and serum albumin were more prominent in the SCH than the euthyroid group. Biochemical changes with aging are useful as potential clues for suspecting latent SCH.
