Abstract
Retroperitoneal fibrosis (RPF) is a rare cause of hydronephrosis and progressive renal dysfunction with unidentified origin. RPF is categorized into idiopathic RPF with/without immunoglobulin G4 (IgG4)-related disease (IgG4-RD), and secondary RPF. Identifying the underlying cause is challenging and often associated with delayed diagnosis or therapeutic interventions. We investigated RPF's clinical characteristics based on different etiologies and factors that may help distinguish the underlying causes. We analyzed the cases of 49 patients with RPF that was radiographically diagnosed at our institution (2008-2022). The cohort was 77.6% males; 75.5% had idiopathic RPF and 24.5% had secondary RPF. Among the idiopathic patients, 54.1% had IgG4-RD. The patients were likely to have abdominal pain, lower back pain/lumbago, and constitutional symptoms including generalized fatigue and fever. The idiopathic patients were likely to have higher serum IgG4 and IgG levels and lower serum C3 levels compared to secondary RPF. The IgG4-RPF patients were likely to have higher serum IgG4 levels and lower serum C-reactive protein, ferritin, and C3 levels compared to the idiopathic RPF patients without IgG4-RD. These findings might reflect underlying systemic inflammatory responses. Comprehensive laboratory testing, including serum inflammatory markers and immunological panels, is recommended for radiologically diagnosed RPF patients.

Abstract
The pandemic of the new coronavirus infection (COVID-19) has yet not only to be converged, but also new infections continue to occur. At least about one-third of the affected patients suffer from various symptoms even after the acute phase. However, effective treatments for sequelae have not yet been established, and the prognosis and risk factors are still unclear. It is possible that endocrine disruption is involved in the occurrence of long COVID. Okayama University Hospital set up a COVID-19 aftercare (CAC) outpatient clinic on Feb. 15 in 2021 to treat patients suffering from sequelae even one month after COVID-19 infection. In the present study, to extract the key factors that affect the onset and course of sequelae, a retrospective analysis was performed by focusing on changes in the number of symptoms and patient background during the three months from the first outpatient visit. Also, we focused on how various sequelae progress in patients who received continuous medical care for 3 months, in which the relationship between the sequelae and the serum COVID-19 antibody titer measured at the first visit was evaluated. In this study, the data from 65 patients who visited our clinic. Presentation: No date and time listed

Abstract
Primary hyperparathyroidism (PHPT) is the most common disorder causing hypercalcemia, in which parathyroid hormone (PTH) is excessively secreted from a parathyroid tumor. PHPT occurs mainly in elderly women, and patient with PHPT present symptoms including nephrolithiasis, bone fracture, and cognitive impairment or can be asymptomatic. Excessive secretion of PTH leads to elevated serum levels of alkaline phosphatase as well as calcium and decreased serum inorganic phosphate level. Parathyroid surgery is the only established treatment, and the treatment reduces elevated serum levels of calcium and PTH, increases bone mineral density, reduces the occurrence of bone fractures, and decreases the risk of renal stones. However, some PHPT patients, especially elderly patients, refuse to undergo surgical therapy for various reasons including perceived risk. Calcimimetic treatment, including cinacalcet and evocalcet administration, has also been reported to be effective for reducing serum calcium level in patients with PHPT. However, the relationship between the efficacy of calcimimetic treatment for PHPT and patient characteristics related to the effectiveness of calcimimetics remains to be elucidated. To investigate the relevance of clinical parameters to the effectiveness of calcimimetics for PHPT, we retrospectively analyzed patients with PHPT who received calcimimetic treatment in our department. We included nine patients including 8 females (88.9%) and one male (11.1%) in the study. The median age of the patients was 81 years (interquartile range (IQR): 61-86 years). Laboratory tests before calcimimetic treatment revealed that median level of serum corrected calcium (cCa) was high (11.1 (IQR: 10.5-12.7) mg/dL), serum inorganic phosphate was low (2.3 (2.3-2.4) mg/dL), and plasma intact PTH was high (251. 0 (198.3-498.5) pg/mL). The fractional excretion of calcium was higher than 1% (1.3% (1.12-1.48%)), %tubular reabsorption of phosphate was low (79.9% (77.1-83.9%)), nephrogenous cyclic adenosine monophosphate (cAMP) was high (3.4 (2.4-4. 0) nmoL/dL GF), and urinary cAMP was normal (4.3 (4. 0-5.3) μmoL/day). Median reduction rate of serum cCa level due to calcimimetic treatment was 5.8% (0-13.4%) at the first follow-up (median treatment duration: 22 (20-29) days). Notably, reduction rate of serum cCa level had significant correlations with age (R=0.95), dual energy X-ray absorptiometry % young adult mean (DEXA %YAM) in the femoral neck (R=-0.92), and urinary cAMP level (R=-0.85). Thus, the present study suggested that elevated serum cCa levels may be reduced by treatment with calcimimetics more effectively in PHPT patients of relatively advanced age, patients with low DEXA %YAM, and patients with low urinary cAMP.

Abstract
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.

Abstract
Aim An increasing number of older adults in Japan are at an increased risk of road traffic crashes. This study aimed to investigate the prevalence of potential underlying medical factors that increase the risk of road traffic crashes among older people. Methods This cross-sectional observational study was conducted in 11 medical institutions in Japan using self-administered questionnaires and physical examination from January to May 2021. The background and social data, data on the use of nursing care insurance, and clinical data suggestive of polypharmacy, sarcopenia, cognitive impairment, and frailty/oral frailty were obtained. The prevalence of these factors was compared between everyday and occasional drivers. Results Data of 127 patients were collected; their median (interquartile range) age was 73 (70–78) years. Of the total participants, 82 were men (64.6%) and 45 were women (35.4%). There were 77 everyday drivers and 50 occasional drivers. Of these, 121 (95.3%) had not applied for nursing care insurance, but the numbers of those who required help 1 and 2 were 1 (0.8%) and 3 (2.4%), respectively. Prevalence of medical factors was as follows: polypharmacy, 27.6%; sarcopenia, 8.7%; dementia, 16.4%; frailty, 15.0%; and oral frailty, 54.3%; it was not significantly different between every day and occasional drivers. Intention to return the car license was significantly higher among the occasional drivers (2.6% vs. 14.0%; odds ratio: 6.7, 95% confidence interval: 1.2–70.6, p = 0.024). Conclusion We uncovered the prevalence of medical factors that can be associated with road traffic crashes among Japanese older people aged ≥ 65 years in our community.

Abstract
Urinary catecholamines (CAs) have been examined for the screening of pheochromocytomas. The decision to perform screening is based on symptoms suggesting secondary hypertension or hyperactivities of the sympathetic nervous system. To elucidate the usefulness of urinary fractions and ratios of CAs, 79 patients in whom 24-h excretions of urinary CAs including adrenaline (AD), noradrenaline (NA) and dopamine (DA) had been examined from 2015 until 2020 were retrospectively analyzed. There were no significant differences in urinary CA levels between two age groups, gender groups and two BMI groups. Patients with histories of preexisting hypertension and diabetes showed significantly higher levels of urinary NA excretion, and the urinary ratio of NA/DA was also increased in the patients with a history of hypertension. Heart rate (HR) was significantly correlated with the urinary ratio of NA/DA. Serum free thyroxine (FT4) concentration and ratio of FT4/thyrotropin (TSH) were correlated with the level of urinary AD. The levels of TSH and FT4/TSH showed negative and positive correlations, respectively, with the urinary NA/DA ratio. Thus, increases of HR are related to the enhanced conversion of DA to NA and increased thyroid hormones are involved in the increase in urinary AD and the conversion of DA to NA. History of lifestyle-related diseases and changes of HR and thyroid functions need to be considered for the evaluation of urinary CAs and their ratios.

Abstract
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.

Abstract
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.

Abstract
Antimicrobial stewardship for outpatients with acute respiratory tract infections (ARTIs) should be urgently promoted in this era of antimicrobial resistance. Previous large-sample studies were based on administrative data and had limited reliability. We aimed to identify current antimicrobial prescription practices for ARTIs by directly basing on medical records. This multicenter retrospective study was performed from January to December in 2018, at five medical institutes in Japan. We targeted outpatients aged ≥18 years whose medical records revealed International Classification of Diseases (ICD-10) codes suggesting ARTIs. We divided the eligible cases into three age groups (18-64 years, 65-74 years, and ≥75 years). We defined broad-spectrum antimicrobials as third-generation cephalosporins, macrolides, fluoroquinolones, and faropenem. Primary and secondary outcomes were defined as the proportion of antimicrobial prescriptions for the common cold and other respiratory tract infections, respectively. Totally, data of 3,940 patients were collected. Of 2,914 patients with the common cold, 369 (12.7%) were prescribed antimicrobials. Overall, compared to patients aged ≥75 years (8.5%), those aged 18-64 years (16.6%) and those aged 65-74 years (12.1%) were frequently prescribed antimicrobials for the common cold (odds ratio [95% confidential interval]; 2.15 [1.64-2.82] and 1.49 [1.06-2.09], respectively). However, when limited to cases with a valid diagnosis of the common cold by incorporating clinical data, no statistical difference was observed among the age groups. Broad-spectrum antimicrobials accounted for 90.2% of the antimicrobials used for the common cold. Of 1,026 patients with other respiratory infections, 1,018 (99.2%) were bronchitis, of which antimicrobials were prescribed in 49.9% of the cases. Broad-spectrum antimicrobials were the main agents prescribed, accounting for nearly 90% of prescriptions in all age groups. Our data suggested a favorable practice of antimicrobial prescription for outpatients with ARTIs in terms of prescribing proportions, or quantitative aspect. However, the prescriptions were biased towards broad-spectrum antimicrobials, highlighting the need for further antimicrobial stewardship in the outpatient setting from a qualitative perspective.

Abstract
Influenza potentially has a high mortality rate when it affects the elderly. We aimed to examine the differences in clinical manifestations in patients with influenza according to their age. This multicenter prospective study was performed in six medical institutions in Okayama and Kagawa prefectures (Japan). Between December 1, 2019 and March 31, 2020, we collected data on adult patients diagnosed with influenza type A, who were strat-ified into younger (20-49 years), middle-aged (50-64 years), and older groups (≥ 65 years). We compared the presence or absence of fever, respiratory symptoms, and extrapulmonary symptoms according to age group. In total, 203 patients (113, younger; 51, middle-aged; and 39, older) were eligible for the analysis. The maxi-mum body temperature and temperature at first physician visit in the older group were significantly lower than those in the younger group. The incidence of respiratory symptoms was not different among the three groups. Chills, muscle pain, and arthralgia as systemic symptoms were noted significantly more frequently in the younger (80.9%) and middle-aged (75.5%) groups than in the older group (51.3%) (p = 0.002). Fever and sys-temic symptoms were less likely to appear in older patients, possibly resulting in the delaying of hospital visits among older adults.

Abstract
Objectives Vitamin D deficiency, which is common worldwide, increases the risks of falls and fractures and can lead to increased morbidity and mortality. However, the clinical utility and relevance of vitamin D activation remain unknown. The aim of the present study was to clarify the clinical usefulness of serum 1,25-dihydroxyvitamin D (1,25D)/25-hydroxyvitamin D (25D) ratio for assessment of the extent of bone metabolism. Methods We retrospectively screened data for 87 patients whose serum 1,25D and 25D levels were measured. Eight patients who were taking vitamin D preparations were excluded, and data for 79 patients (33 males and 46 females) were analyzed. Since menopausal status can be associated with serum vitamin D level, we divided the patients by gender and divided the female patients into two groups at the age of 50 years. Results The median serum 1,25D/25D ratio was significantly lower in males than in females, with the most considerable difference in all males [4.1 (interquartile range: 2.3-5.8) × 10-3] versus elderly females (aged ≧50 years) [7.9 (3.3-10.1) × 10-3). Main disorders were endocrine (30.6%), inflammatory (18.5%), and bone-related (16.7%) disorders. The ratios of serum 1,25D/25D had significant negative correlations with femoral dual-energy X-ray absorptiometry % young adult mean (DEXA %YAM) (R=-0.35) and lumbar DEXA %YAM (R=-0.32). Significant correlations were found between the 1,25D/25D ratio and serum levels of inorganic phosphate (iP), parathyroid hormone, and alkaline phosphatase (ALP). The 1,25D/25D ratio had gender-specific characteristics: the ratio was significantly correlated with age in males (R=-0.49), while it was significantly correlated with BMI in females (R=0.34). Conclusions The results of this study suggested that vitamin D activity is negatively correlated with bone mineral density, being reduced in aged males but enhanced in obese females.

Abstract
Abstract
Corticosteroids are important bioactive substances in the body that regulate inflammation, metabolism, immunity, and circulatory dynamics. Cortisol and aldosterone are two major naturally occurring steroids, which synthesized in the adrenal fasciculata and in the adrenal glomerulosa under the regulation of adrenocorticotropin (ACTH) and renin-angiotensin system (RAS), respectively. The conventional strategy for evaluating adrenocortical function has been to measure random serum cortisol or 24-hour stored levels of urine free cortisol (UFC). UFC is a more appropriate marker to avoid the effects of diurnal fluctuation of cortisol, serum cortisol-binding proteins, and cortisol clearance in the kidney. Thus, measurement of UFC has been a reliable test for diagnosis of Cushing’s disease or adrenal insufficiency. However, since the normal range of UFC varies widely, it is often difficult to evaluate whether the UFC level is optimal or not for each patient. That is because UFC is greatly affected by the amount of fluid intake or urine volume, and an immunoassay for UFC, which is the usual method for measuring UFC, is susceptible to interference from other steroid metabolites and synthetic glucocorticoids. To explore an alternative indicator, we tried to standardize the levels of UFC by the levels of urinary aldosterone concentration (UAC) in the same urinary sample. Medical records of all 246 patients in whom daily excretions of UFC and UAC had been measured between 2015 and 2018 at our department were reviewed. 142 patients (including 93 females) were included after exclusion of 104 patients because of corticosteroid replacement therapy. UFC/UAC ratio showed significant positive and negative correlations with the levels of serum cortisol (R=0.287) and aldosterone (R=-0.762), respectively. UFC/UAC ratio increased with aging in female patients, while the ratio was not altered by the levels of BMI in either gender. Markers for metabolic and inflammatory status including hemoglobin A1c (R=0.327), albumin (R=-0.331), chorine esterase (R=-0.248), C-reactive protein (R=0.317), ferritin (R=0.473), and D-dimer (R=0.569) showed correlations to the ratio of UFC/UAC that were more significant than the correlations to the serum level of cortisol or UFC alone. Of note, the UFC/UAC ratio was shown as an indicator for risks of diabetes (AUC: 0.765), hypoalbuminemia (0.839), hyper-CRPemia (0.748), and thrombophilia (0.824), in which the cut-off levels of UFC/UAC ratios were found to be around 12. These results indicate that the UFC/UAC ratio is a suitable variable for the detection of metabolic and inflammatory complications related to adrenocortical dysfunction.

Abstract
Abstract
Various laboratory markers are utilized in general practice to detect inflammation, and procalcitonin (PCT) has also been routinely measured in many patients as a marker of bacterial infection and sepsis. An increase in PCT starts before an increase in C-reactive protein (CRP), and PCT level is useful not only for the diagnosis of bacterial infection, sepsis, as an indicator of the severity and prognosis of systemic inflammatory diseases, and is also useful for determination of the response to individual treatment. PCT is a precursor of calcitonin and PCT is not produced in a healthy state but is produced by various tissues in septic conditions. Since there are many patients with elevated levels of PCT due to nonbacterial causes, the levels of serum PCT have been apt to be used for a marker for the early detection of not only bacterial infection but also many inflammatory and/or febrile disorders including fever of unknown origin (FUO) in the clinical setting of general medicine. Here we attempted to clarify the differences and similarities of inflammatory markers for a clinical setting. We retrospectively reviewed 359 patients in whom serum PCT had been measured. According to our earlier study, the patients were categorized into 7 groups: bacterial, non-bacterial infection, non-specific inflammation, neoplasm, connective tissue disease (CTD), drug-induced diseases, and unidentified causes. Data for 332 PCT-positive cases including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), CTD (8.4%), and non-bacterial infection (7.2%) were used for analysis. Serum PCT level was highest in the bacterial infection group (1.94 ng/ml) followed by the non-specific inflammatory group (0.58 ng/ml) and neoplastic diseases group (0.34 ng/ml). Of note, serum PCT level was positively correlated with serum levels of C-reactive protein (R2=0.39), soluble interleukin-2 receptor (sIL-2R; R2=0.48), and ferritin, plasma level of D-dimer level and white blood cell count, whereas it was negatively correlated with serum albumin level (R2=0.27), hemoglobin concentration and platelet count. The result of the strongly positive correlation with serum level of sIL-2R suggested that an increased serum PCT level may indicate not only an inflammatory state but also a neoplastic state such as malignant lymphomas in the diagnostic process of various inflammatory disorders in a clinical setting of general practice for diagnosing febrile conditions.

Abstract
Vitamin D is obtained in the body by food intake or by production from 7-dehydrocholesterol by exposure of the skin to ultraviolet B radiation. It is first metabolized in the liver to 25-hydroxyvitamin D (25D), which is a major circulating metabolite. In the kidney, 25D is subsequently metabolized to the hormonally active form, 1,25-dihydroxyvitamin D (1,25D), via 1α-hydroxylase encoded by the CYP27B1 gene. 1,25D has a cellular effect through the vitamin D receptor, which leads to calcium absorption in the gut, bone metabolism, and parathyroid function. A recent study showed that a low vitamin D status is common worldwide and is associated with various diseases including kidney, heart, and liver failure, secondary hyperparathyroidism, osteomalacia, inflammatory bowel disease, granuloma-forming disorders (sarcoidosis and tuberculosis), and cancer. Vitamin D deficiency also increases the risks of falls, fractures, bone loss, sarcopenia, leading to worse outcomes of illness severity, morbidity, and mortality. The 1,25D/25D ratio is considered to be a useful tool for diagnosis of ocular sarcoidosis; however, its clinical utility and relevance to pathophysiology of evaluation of the ratio 1,25D/25D which indicates vitamin D activation have remained unknown. To clarify the clinical usefulness of markers for vitamin D activation, 87 patients in whom serum 25D and 1,25D level was measured were retrospectively reviewed in the present study. Data for 79 patients (33 males and 46 females) were analyzed after exclusion of 8 patients taking vitamin D. The median serum 1,25D/25D ratio was significantly lower in males than in females: 4.1 (IQR: 2.3–5.8) x 10−3 versus 6.8 (3.0–9.8) x 10−3. However, individual levels of 25D and 1,25D were not different in males and females. The major categories of main disorders were endocrine (30.6 %), inflammatory (18.5 %), and bone-related (16.7 %) disorders. The ratios of serum 1,25D/25D had significant negative correlations with femoral dual energy X-ray absorptiometry % young adult mean (DEXA %YAM) (R=-0.35) and lumbar DEXA %YAM (R=-0.32). Significant correlations were found between 1,25D/25D ratio and serum levels of inorganic phosphate (R=-0.34), intact parathyroid hormone (R=0.64) and alkaline phosphatase (R=0.46) in all patients. Of interest, the 1,25D/25D ratio had gender-specific characteristics: the ratio had a significant correlation with age in males (R=0.49), while it had a significant correlation with body mass index (BMI) in females (R=0.34). Collectively, the results revealed that the ratio of serum 1,25D/25D as a marker for activation of vitamin D had relevance to clinical parameters, especially bone turnover, with gender-specific features. It is suggested that the existence of a gender-specific difference of aging males and obese females regarding the activation of vitamin D that is functionally linked to bone metabolism.

Abstract
OBJECTIVE Insulin-like growth factor-1 (IGF-1) is an anabolic hormone, the levels of which decline with age. The present study aimed to determine the impact of age-related declines in serum IGF-1 levels on various physiological processes. DESIGN We retrospectively reviewed the medical records of patients whose serum IGF-1 levels were estimated in our department, and assessed the relationships between serum IGF-1 levels and various physiological parameters. RESULTS A total of 427 patients with a mean (± standard deviation) age of 52.8 (± 17.1) years were included in the analysis. The levels of serum IGF-1 showed significant positive correlation with those of hemoglobin and hematocrit, and negative correlation with the presence of inflammatory and fibrin-related markers including C-reactive protein (CRP) and procalcitonin (PCT), and D-dimer and fibrin degradation products (FDP). These tendencies persisted after exclusion of patients with pituitary disease. CONCLUSIONS In this study population of diverse diseases and backgrounds, a decline in serum IGF-1 levels with age was associated with an increase in inflammatory and fibrin-related markers. This may explain the correlation between low serum IGF-1 levels and an increased risk of cardiovascular events. Our findings suggest that serum IGF-1 is a clinically relevant marker of cardiovascular risk, particularly in males.

Abstract
PURPOSE The aim of the present study was to determine how age-related decreases in serum dehydroepiandrosterone sulfate (DHEAS) levels affect various physiological processes. METHODS We retrospectively reviewed the medical records of patients in whom serum DHEAS levels were measured in our department and assessed the relationships between serum DHEAS levels and various patient characteristics. RESULTS Among the 149 patients included in our analysis (mean age: 52.7 ± 17.6 years, range: 15-84 years), 54 (36.2%) were men. Serum DHEAS levels inversely correlated with age in men (R = -0.810, p < .01) and to a lesser extent in women (R = -0.391, p < .01). Of note, there were significant positive associations between DHEAS levels and hemoglobin (R = 0.317, p ≤ .01) and hematocrit (R = 0.324, p ≤ .01) levels, which were observed in men, but not in women. CONCLUSIONS Our study suggests that reduced DHEAS secretion inhibits erythropoietic activity in aging men, perhaps owing to the erythropoietic androgenic actions of DHEAS. Importantly, it suggests that the age-associated decline in DHEAS secretion might decrease erythropoietic activity in aging men. It is also possible that the adrenal cortex, the source of DHEAS, is dysfunctional in anemic men.

Abstract
Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that the BAP/ALP ratios of the patients with fever and those with inflammatory diseases were significantly lower than the ratios of other patient groups. The BAP/ALP ratios of the patients with osteoporosis and those with metabolic bone diseases were higher than those of the patients with other conditions. The BAP/ALP ratio was found to be negatively correlated with age, a cor-relation that has not been found in other ethnicities. The serum BAP/ALP ratio was inversely correlated with serum CRP levels but was positively correlated with serum albumin levels and hemoglobin concentrations. Collectively, our results suggest that the BAP/ALP ratio could be a useful predictor for important geriatric con-ditions seen in general practice.

Abstract
To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=-0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status.

Abstract
To clarify the potential relevance of patients' chief complaints at a general medicine department to their self-rating depression scale (SDS) and frequency scale for symptoms of gastroesophageal reflux disease (GERD) (FSSG) scores, we analyzed data of 478 patients who visited our general medicine department. The chief complaints (553 symptoms of 447 patients) were categorized into major symptom-based groups: respiratory (31%), circulatory (3%), gastrointestinal (GI) tract (26%), neurology (8%), orthopedic and skin (10%), and systemic (22%) symptoms. The SDS score tended to be higher in females and younger patients. The FSSG score did not differ by gender but was higher in younger patients. The patients receiving social welfare had higher SDS and FSSG scores. A close inter-relationship between the FSSG (including both degrees of reflux and dysmotility) and SDS was observed in all patients. Although the averages of the SDS and FSSG scores were not significantly different among the symptom-based categories, we observed significantly positive correlations between the FSSG and SDS in each category, suggesting that depressive status may be closely related to GERD-related symptoms regardless of the patients' chief complaints. An initial checkup of patients' psychological condition and/or GERD-like symptoms could help screen for latent disorders in outpatients with uncertain complaints.

Abstract
PRL is a polypeptide hormone that is, in phylogeny, well conserved but elicits various species-dependent functions. PRL is related to the regulation of osmotic pressure in fish and amphibians, fat retention in reptiles and birds, and glucose-lipid metabolism, bone homeostasis and development of the mammary gland in mammals. In humans, PRL secretion is regulated in an inhibitory manner by dopaminergic neurons that project from the hypothalamus to PRL-producing cells in the anterior pituitary gland. Since dopaminergic actions are mainly mediated by D2R, various agents that bind D2R can affect serum PRL levels. In the clinical aspect, hyperprolactinemia is considered in cases with galactorrhea, infertility and sexual dysfunction. Other causes of hyperprolactinemia include hypothyroidism, chronic kidney disease and pregnancy. Also, PRL receptors have been considered as therapeutic targets for some cancers and autoimmune diseases. Given that several pathophysiological functions related to PRL have been recently uncovered, the utility of measuring serum PRL levels could be more widely applicable for a clinical setting. We therefore attempted to reveal the relevance of PRL levels to various clinical parameters in patients who visited a general medicine department. We reviewed medical records of 353 patients whose serum PRL levels were measured in our department during the period from 2016 to 2018. Patients lacking detailed clinical records (n=194) and patients taking medications that affect D2R (n=19) were excluded from this study. Data were analyzed for 140 patients (42 males, aged 49 ± 18 years; 98 females, 45 ± 19 years) in whom various pain and general fatigue were major symptoms at the first visit and in whom hypertension and dyslipidemia were frequently seen in past histories. Average PRL levels were significantly lower in males than in females. The median PRL level in males was 6.5 ng/ml (IQR: 4.2–10.3) ng/ml and that in females was 8.1 ng/ml (5.9–12.9). Patients were divided into two groups depending on whether PRL levels were higher than 10 ng/ml. The group of males with relatively high PRL levels (≥10 ng/ml) had significantly lower levels of serum albumin and higher levels of serum LDH. Of note, there were significant correlations of male PRL levels to erythrocyte sedimentation rate (ESR) (r=0.6), serum LDH (r=0.4) and albumin level (r=-0.5), and TSH/FT4 ratio (r=0.5). On the other hand, female PRL levels were negatively correlated to age (r=-0.2) and serum levels of FSH (r=-0.3) and positively correlated to serum levels of GH (r=0.3). Collectively, the results revealed that PRL levels had gender-specific relevance to various clinical factors. It is notable that PRL levels in males were related to inflammatory status shown by high ESR and low serum albumin and were also associated with a hypothyroid condition.

Abstract
A relationship between diabetes and depression is apparent. To clarify the clinical relevance of diabetic patients' gastroesophageal symptoms to their psychological status, we retrospectively analyzed the data from a Selfrating Depression Scale (SDS) and a Frequency Scale for Symptoms of Gastroesophageal reflux disease (FSSG) among 143 type 2 diabetic patients who visited a general medicine department. Among the 45 Japanese patients enrolled, the group with relatively high SDS scores (≥ 36) showed higher (FSSG) dysmotility symptom scores versus the low-SDS (< 36) group, although the 2 groups' characteristics and laboratory data were not significantly different. Positive correlations of postprandial plasma glucose (PPG) levels with FSSG scores (R=0.321, p<0.05), particularly with reflux scores (R=0.455, p<0.01) were revealed. PPG and HbA1c levels were not correlated with SDS scores. The patients' SDS scores were significantly correlated with their FSSG scores (R=0.41, p<0.01), suggesting that depressive status is linked to GERD-related manifestations. Considering that the patients' PPG levels were correlated with GERD-related symptoms, diabetic patients' blood glucose levels are associated with depressive status. Collectively, key symptoms related to GERD and glucose level values would be helpful.

Abstract
Osteoporosis increases the risk of bone fractures. It is diagnosed based on an individual's bone mineral density (BMD) or a fracture without trauma. BMD is usually measured by the dual energy X-ray absorptiometry (DXA) method. Here we investigated factors for the earliest possible prediction of decreased BMD by examining the relationships between patients' BMD values and changes in the patients' physical and laboratory values. We retrospectively reviewed the medical records of 149 patients who visited our department in 2014-2015 for a variety of reasons and underwent an area BMD examination by DXA. We analyzed the relationships between decreasing BMD and the patients' gender, age, body mass index (BMI), medical background, hemoglobin, electrolytes, and thyroid function. Thirty-nine of the patients were diagnosed with osteoporosis based on their T-scores. An adjusted analysis showed that female gender, aging, and increased serum calcium level were significantly related to decreasing femoral BMD, whereas high BMI was associated with an increase in femoral BMD. Collectively the results indicate that for the early detection of low BMD, it is important for general-practice physicians to consider conducting a BMD checkup when treating female and elderly patients with a low BMI and/or elevated serum calcium level.

Abstract
Objective: To differentiate patients with IgG4-related diseases (RD) from patients with other hyper IgG4 conditions who visit general medicine department.Methods: Fifty-six patients with high serum IgG4 levels (>135 mg/dL) were classified into three groups based on the final diagnosis: definite and possible IgG4-RD and others. Clinical and laboratory characteristics of the three groups of patients were retrospectively analyzed.Results: Major manifestations were renal dysfunction and general malaise, while thirst was the most frequent symptom in the definite group, in which submandibular glands and lymph nodes were likely to be affected. Biopsy of minor salivary glands was the least diagnostic for IgG4-RD despite the high frequency of biopsy. In the definite group, serum levels of IgG4 and IgG, IgG4/IgG ratio and basophil number were increased, while serum levels of CRP, IgA and complements were decreased. A negative correlation between serum levels of IgG4 and IgM was found in the definite group.Conclusion: The results indicated that in patients with renal dysfunction, malaise, thirst or weight loss, measurements of the levels of basophils, immunoglobulins and complements are helpful for diagnosing IgG4-RD. Considering distribution of affected tissues and localization of diagnostic biopsies, physical examination and laboratory workup are required for early diagnosis.

Abstract
Dehydroepiandrosterone (DHEA) is a steroid hormone produced in the adrenal cortex. It is synthesized from pregnenolone and further metabolized to androstenedione, testosterone, and estrogen. DHEA and its sulfated ester (DHEAS) are the most abundant circulating steroids in humans. DHEAS is converted to DHEA in a linear manner. Since its serum concentration is 300-500 times higher than that of DHEA, DHEAS serves as a circulating reservoir for DHEA. DHEAS secretion increases during adrenarche, peaks between the ages of 15-25 years, and decreases steadily with age thereafter. This age-related decline in DHEAS secretion is termed adrenopause and is presumably the result of the normal aging processes.DHEAS has recently attracted widespread attention because of its anti-aging effects. However, since studies of the physiological effects of DHEAS in specific organ systems are limited, it is unclear how DHEAS contributes to anti-aging. DHEAS may also extend lifespan: several prospective population-based studies associate low DHEAS levels with high mortality rates, especially in elderly men. Toward the goal of determining a mechanistic basis for these actions of DHEAS, we assessed the relationships between serum DHEAS levels and various patient characteristics. The aim of the present study was to determine how age-related decreases in serum DHEAS levels affect various physiological processes.We retrospectively reviewed the medical records of patients in whom serum DHEAS levels were measured in our department, and assessed the relationships between serum DHEAS levels and various patient characteristics. Among the 149 patients included in our analysis (mean age: 52.7±17.6 years, range: 15-84 years), 54 (36.2%) were men. Serum DHEAS levels inversely correlated with age in men (R = -0.810, p < 0.01) and to a lesser extent in women (R = -0.391, p < 0.01). In women, age better correlated with DHEAS/ACTH ratios (R = -0.444, p < 0.01) than DHEAS levels. Of note, there was a significant positive association between DHEAS levels and hemoglobin (R = 0.419, p < 0.01) and hematocrit (R = 0.375, p < 0.01) levels in men but not women.Collectively, our data indicate that reduced DHEAS secretion inhibits erythropoietic activity in aging men, possibly owing to the erythropoietic androgenic actions of DHEAS. Importantly, these findings suggest that the age-associated decline in DHEAS secretion might decrease erythropoietic activity in aging men. It is also possible that the adrenal cortex, the source of DHEAS, is dysfunctional in anemic men.

Abstract
Osteoporosis is known as a disease that can increase the risk of fracture because of low bone mineral density (BMD). Bone fracture is associated with an increase in mortality in the elderly. It has been reported that femoral bone fracture occurred in 11,578 people in Japan every year during the period from 2008 to 2013. However, in the Japanese population, the average rate of osteoporosis examination is less than 5%. Because of the low rate of consultation for bone examination, it is difficult for general practitioners to detect an early stage of osteoporosis. According to the Ministry of Health, Labour and Welfare, in the current super-aged society in Japan, escalating healthcare costs over the past few decades have been a major problem for maintaining the universal health insurance coverage. Approximately 60% of the total national medical care expenditure is for people over 65 years of age. In Japan, there are about 13 million osteoporosis patients. This causes an increase in medical expenses for elderly and bone fractures lead to an increase in the risk of mortality. In order to reduce the incidence of bone fractures, efforts should be made to reduce the number of patients with low BMD. If physicians can pay attention to the influencing factors in losing BMD, they should be able to detect osteoporosis in an early stage. Earlier detection of low BMD and its treatment would result in reduction in the incidence of bone fractures in elderly patients. In the present study, we attempted to clarify the risk factors that are involved in lowered BMD for patients with various clinical backgrounds who visit Department of General Medicine of a University Hospital, Japan. We retrospectively reviewed medical records for 149 patients who visited our department in our hospital and underwent a BMD examination by the dual energy X-ray absorbance method during the period from 2014 to 2015. We analyzed various physical and laboratory factors that might be associated with lowered BMD. There were 39 patients diagnosed with osteoporosis based on the T-score. Adjusted analysis showed that female gender, aging and increased levels of serum calcium were statistically related to lowered femoral BMD, whereas body mass index was associated with an increase in femoral BMD. In conclusion, it is important for general practitioners to examine BMD in patients who may have low BMD in the viewpoints of gender and aging. Attention should also be given to the possibility of low BMD, patients with high serum calcium levels, patients with anorexia and malnutrition, and patients taking antipsychotic/sleeping drugs or proton pump inhibitors.

Abstract
We retrospectively analyzed the cases of 148 febrile patients whose body temperature (BT) was ≥ 37.5°C at our hospital. We categorized them into seven groups; those with bacterial and viral infection, nonspecific inflammation, neoplasm, connective tissue disease (CTD), drug-induced disease, and unidentified causes. Our analysis revealed that the patient's BT at the 1st visit (BT-1st visit) and highest BT during the febrile period (BT-max) differed significantly among all categories except neoplasm. The greatest difference between BT-1st visit and BT-max was highest in the CTD group (1.5°C). Positive correlations of heart rate and C-reactive protein (CRP) level with BT-max and a negative correlation between serum sodium level with BT-max were uncovered. The serum thyroid-stimulating hormone (TSH) level and the ratio of TSH/free thyroxine were negatively correlated with BT-max, especially in the viral infection group, suggesting the existence of occult thyrotoxicosis in accord with a febrile condition, possibly leading to febrile tachycardia. A febrile gap between BT-1st visit and BT-max (except in the neoplasm group) was shown, in which BT-max was correlated with thyroid function. Clinicians should recognize the fluctuation of BT when diagnosing febrile patients, and tachycardia in such febrile patients may be, at least in part, associated with subclinical thyroid dysfunction.

Abstract
To clarify potential relationships between chief complaints of patients and laboratory data with a focus on aging-related changes, we retrospectively analyzed the data of 843 patients who visited a general medicine department for the first time. Their chief complaints were classified into 8 major symptoms: visceral pain, somatic pain, fever, cough, dizziness, fatigue, appetite loss, and edema. We compared the laboratory data obtained from the patients with complaints with the data of symptom-free (control) patients. The serum sodium and potassium levels in the fever group were decreased compared to those in the control group. In the fever group, the serum sodium level was inversely correlated with age. The ratio of serum urea nitrogen to creatinine (UN/Cr) was increased in the appetite-loss group. There were significant age-dependent increases in the UN/Cr ratio in the appetite-loss and edema groups. Of note, serum levels of free thyroxin were lower in the dizziness group compared to the control group. In addition, the free thyroxin level was inversely correlated with age in the dizziness group but not in the asymptomatic control group. Collectively, the results indicated that osmolality-related laboratory data are strongly associated with individual primary symptoms at the first visit regardless of the final diagnosis. The consideration of age-dependent changes of these markers is helpful for diagnosing latent disorders based on various primary symptoms.

Abstract
Purpose: The purpose of present study was to evaluate the clinical efficacy of irbesartan on the anti-inflammatory and anti-oxidative stress effect in patients with hypertension compared to other ARBs. Further, we assessed the effect of the ARBs on kidney function and urinary albumin excretion. Methods: Eighty-five outpatients with hypertension who took an ARB except irbesartan more than 3 months were assigned into two groups, one continued the same ARB and the other switched the ARB to irbesartan for 6 months. Results: Although blood pressures were equally controlled (continue group: 148 ± 2/79 ± 2 mmHg to 131 ± 2/74 ± 2 mmHg; switch group: 152 ± 2/81 ± 2 mmHg to 132 ± 2/74 ± 2 mmHg; p < 0.001 each), the inflammatory markers (hsCRP, PTX3, MCP-1) and oxidative stress marker (MDA-LDL) did not change after 6 months in both groups. Urinary albumin excretion was significantly reduced only in the switch group without renal function deterioration (switch group 292.4 ± 857.9 mg/gCr to 250.6 ± 906.5 mg/gCr, p = 0.012). Conclusion: These results provide knowledge of the characteristics of irbesartan, suggesting appropriate choice of ARBs in the treatment for hypertension should be considered.

Abstract
The aim of this study was to determine the relationships between free testosterone (FT) level and parameters including laboratory data and data from questionnaires and to determine symptoms leading to the detection of late onset hypogonadism (LOH). We retrospectively reviewed medical records of patients in whom serum FT was measured in our hospital. Aging Male Symptoms (AMS) score, self-rating depression scale (SDS) and frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score were used for questionnaires. A total of 205 patients were included in the analysis (55.2 ± 15.6 years of age, mean ± SD). Among them, 119 patients (58.0%) had an FT level of less than 8.5 pg/mL, which fulfills the diagnostic criterion of LOH syndrome according to the clinical practice manual for LOH in Japan. It was revealed that FSSG score was inversely correlated to serum FT levels (r = -0.3395, p < 0.001), although SDS and AMS scales did not show significant correlations to FT levels. Our study revealed a high prevalence of LOH syndrome among patients in whom the majority complained of general symptoms. Although GERD symptoms are generally not considered to be typical symptoms of LOH, our study indicates that those symptoms might be clues for the detection of LOH.

Abstract
A 72-year-old Japanese woman presented with a fever, diarrhea, intermittent spotting, and constant fluid discharge from the vagina. Imaging studies revealed an enterovaginal fistula. She underwent radical hysterectomy and radiotherapy 35 years previously. She also had a surgical history of nephrostomy, nephrectomy, ileoascending anastomosis, and colostomy. As bleeding from the enterovaginal fistula was uncontrollable, ileocecal resection was performed. However, a colovesical fistula with urinary tract infection occurred 3 months later. The present case indicates that fistula formation occurs and causes various symptoms in patients who underwent postpelvic radiotherapy, particularly in those with prior surgeries in the irradiated field.

Abstract
We herein report the first documented case of acute hypersensitivity pneumonitis in which Candida guilliermondii was the possible causative organism. A young Japanese woman presented to our hospital with relapsing respiratory symptoms accompanied by high fever. A detailed interview revealed that the onset of the symptoms occurred shortly after using a humidifier in her home. Her symptoms showed spontaneous improvement soon after admission, and an examination of her bronchoalveolar lavage fluid revealed the specific infiltration of inflammatory cells, which predominantly consisted of lymphocytes. Precipitin testing showed a positive reaction to C. guilliermondii, which was isolated from the home humidifier. Repeated history taking is essential for diagnosing occult respiratory disorders.

Abstract
Objective To analyze the clinical and endocrine characteristics of patients with primary adrenal lymphoma. Patients We retrospectively reviewed the cases of five patients with primary adrenal lymphoma who were treated in our hospital between April 2004 and March 2015. We investigated the characteristics of the clinical and pathological findings, treatment, prognosis and complications of adrenal insufficiency. Results Adrenal insufficiency, which was confirmed by the laboratory data at the initial presentation, was observed in two cases. One case was complicated by relative adrenal insufficiency during a course of chemotherapy. The plasma adrenaline and urinary adrenaline levels were decreased in four cases and three cases, respectively. Diffusion MRI was radiologically diagnostic. In all of the cases, the patients were pathologically diagnosed with diffuse large-B cell lymphoma and were treated with rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone)-like chemotherapy. Two patients received central nervous system prophylaxis with high-dose methotrexate. Four of the patients survived and one patient died during the follow-up period. Conclusion The early detection of adrenal insufficiency and the administration of an appropriate dose of hydrocortisone are necessary during the course of chemotherapy as well as at the initial manifestation. The exclusion of adrenal dysfunction prior to invasive diagnostic procedures, such as CT-guided needle biopsy, is also critical.

Abstract
A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here, we discuss the risk of malignancies, particularly malignant lymphoma in patients with IgG4-related disease. The importance of pathological analysis to reach the appropriate diagnosis in such cases should be emphasized.

Abstract
Fitz-Hugh-Curtis syndrome is characterized by an inflammation of the perihepatic capsules associated with pelvic inflammatory disease. The typical symptom is severe right upper quadrant abdominal pain. We report a patient with Fitz-Hugh-Curtis syndrome who presented with an atypical chief complaint of right-side chest pain unaccompanied by symptoms specific to pelvic inflammatory disease. This case indicates that Fitz-Hugh-Curtis syndrome should be considered in the differential diagnosis of right-side chest pain in young women, because early diagnosis and treatment of the disease are essential to prevent chronic complications.

Abstract
Insulinoma is a rare, usually benign, pancreatic neuroendocrine tumor. The clinical features of an insulinoma are fasting hypoglycemia with neuroglycopenic symptoms including confusion and unusual behavior, while hypertension is usually not associated with the disease. We herein report a patient with insulinoma who manifested paroxysmal hypertension and neuroglycopenic symptoms. The possible etiology of hypertension induced by an insulinoma is catecholamine release in response to hypoglycemia, which may cause acute hypertension through activation of the sympatho-adrenal system. This case implies that sustained hyperinsulinemia due to insulinoma can be functionally linked to the induction of paroxysmal hypertension.

Abstract
A 60-year-old woman with rheumatoid arthritis treated with methotrexate for a decade complained of slight epigastric discomfort. A positive cytomegalovirus (CMV) antigenemia test indicated the probability of CMV-related gastrointestinal infection, for which esophagogastroduodenoscopy was performed. Endoscopic findings showed a non-specific duodenal mucosal lesion;however, pathological investigation revealed evidence of CMV duodenitis. There is scarce information on the clinical and pathological features of CMV-related duodenitis, likely due to its low prevalence. CMV infection in the upper gastrointestinal tract should be considered as a differential diagnosis in high-risk individuals, particularly those with symptoms relating to the digestive system. Biopsy examinations are preferable for the definitive diagnosis of CMV gastrointestinal infection, even without specific endoscopic features.

Abstract
KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels. Following tapering of prednisolone, chest image findings deteriorated again as levels of KL-6 increased, suggesting recurrence of RA-ILD. Bronchoscopic examination revealed active MAC infection. Treatment of MAC infection not only improved chest image findings but also decreased KL-6 levels in serum, suggesting that KL-6 was increased by active MAC infection by itself, not by recurrence of RA-ILD. To the best of our knowledge, this is the first documentation of KL-6 elevation in serum in association with active MAC infection.

Abstract
An 81-year-old Japanese male with primary Sjögren syndrome (pSS) developed a low-grade fever and productive cough which were refractory to antibiotic therapy. Based on the high level of eosinophils observed in his bronchial alveolar lavage, he was diagnosed with chronic eosinophilic pneumonia (CEP) and successfully treated by oral prednisolone. Interstitial lung diseases associated with pSS (pSS-ILDs) usually present as nonspecific interstitial pneumonia or usual interstitial pneumonia; therefore, the present case is extremely unique in that the patient's condition was complicated with CEP. A diagnosis of advanced gallbladder cancer was made in the patient's clinical course, suggesting the advisability of a whole-body workup in cases of pSS, especially in elderly patients.

Abstract
A 74-year-old man who had been administered trimethoprim-sulfamethoxazole for three weeks suffered from drug-induced hypersensitivity syndrome/drug rash with eosinophilia and systemic symptoms (DIHS/DRESS). In the early stage of the clinical course, he developed renal dysfunction. A renal biopsy showed granulomatous tubulointerstitial nephritis accompanying the proliferation of human herpes virus (HHV)-6 in tubular epithelial cells. With corticosteroid therapy, the systemic rash and renal function gradually improved. The present patient is the second case of DIHS/DRESS demonstrating a possible reactivation of HHV-6 in the renal tissue. The clinical role of viral reactivation in DIHS/DRESS must be further elucidated.
