RESUMO
BACKGROUND: An analysis of European and American individuals revealed that a reduction in estimated glomerular filtration rate (eGFR) slope by 0.5 to 1.0 mL/min/1.73 m2 per year is a surrogate endpoint for end-stage kidney disease (ESKD) in patients with early chronic kidney disease. However, it remains unclear whether this can be extrapolated to Japanese patients. METHODS: Using data from the Japan diabetes comprehensive database project based on an advanced electronic medical record system (J-DREAMS) cohort of 51,483 Japanese patients with diabetes and a baseline eGFR ≥ 30 mL/min/1.73 m2, we examined whether the eGFR slope could be a surrogate indicator for ESKD. The eGFR slope was calculated at 1, 2, and 3 years, and the relationship between each eGFR slope and ESKD risk was estimated using a Cox proportional hazards model to obtain adjusted hazard ratios (aHRs). RESULTS: Slower eGFR decline by 0.75 mL/min/1.73 m2/year reduction in 1-, 2-, and 3-year slopes was associated with lower risk of ESKD (aHR 0.93 (95% confidence interval (CI) 0.92-0.95), 0.84 (95% CI 0.82-0.86), and 0.77 (95% CI 0.73-0.82), respectively); this relationship became more apparent as the slope calculation period increased. Similar results were obtained in subgroup analyses divided by baseline eGFR or baseline urine albumin-creatinine ratio (UACR), with a stronger correlation with ESKD in the baseline eGFR < 60 mL/min/1.73 m2 group and in the baseline UACR < 30 mg/gCre group. CONCLUSION: We found that changes in the eGFR slope were associated with ESKD risk in this population.

BACKGROUND & AIMS: Medication is a major determinant of human gut microbiome structure, and its overuse increases the risks of morbidity and mortality. However, effects of certain commonly prescribed drugs and multiple medications on the gut microbiome are still underinvestigated. METHODS: We performed shotgun metagenomic analysis of fecal samples from 4198 individuals in the Japanese 4D (Disease, Drug, Diet, Daily life) microbiome project. A total of 759 drugs were profiled, and other metadata, such as anthropometrics, lifestyles, diets, physical activities, and diseases, were prospectively collected. Second fecal samples were collected from 243 individuals to assess the effects of drug initiation and discontinuation on the microbiome. RESULTS: We found that numerous drugs across different treatment categories influence the microbiome; more than 70% of the drugs we profiled had not been examined before. Individuals exposed to multiple drugs, polypharmacy, showed distinct gut microbiome structures harboring significantly more abundant upper gastrointestinal species and several nosocomial pathobionts due to additive drug effects. Polypharmacy was also associated with microbial functions, including the reduction of short-chain fatty acid metabolism and increased bacterial stress responses. Even nonantibiotic drugs were significantly correlated with an increased antimicrobial resistance potential through polypharmacy. Notably, a 2-time points dataset revealed the alteration and recovery of the microbiome in response to drug initiation and cessation, corroborating the observed drug-microbe associations in the cross-sectional cohort. CONCLUSION: Our large-scale metagenomics unravels extensive and disruptive impacts of individual and multiple drug exposures on the human gut microbiome, providing a drug-microbe catalog as a basis for a deeper understanding of the role of the microbiome in drug efficacy and toxicity.

BACKGROUND & AIMS: To identify gut and oral metagenomic signatures that accurately predict pancreatic ductal carcinoma (PDAC) and to validate these signatures in independent cohorts. METHODS: We conducted a multinational study and performed shotgun metagenomic analysis of fecal and salivary samples collected from patients with treatment-naïve PDAC and non-PDAC controls in Japan, Spain, and Germany. Taxonomic and functional profiles of the microbiomes were characterized, and metagenomic classifiers to predict PDAC were constructed and validated in external datasets. RESULTS: Comparative metagenomics revealed dysbiosis of both the gut and oral microbiomes and identified 30 gut and 18 oral species significantly associated with PDAC in the Japanese cohort. These microbial signatures achieved high area under the curve values of 0.78 to 0.82. The prediction model trained on the Japanese gut microbiome also had high predictive ability in Spanish and German cohorts, with respective area under the curve values of 0.74 and 0.83, validating its high confidence and versatility for PDAC prediction. Significant enrichments of Streptococcus and Veillonella spp and a depletion of Faecalibacterium prausnitzii were common gut signatures for PDAC in all the 3 cohorts. Prospective follow-up data revealed that patients with certain gut and oral microbial species were at higher risk of PDAC-related mortality. Finally, 58 bacteriophages that could infect microbial species consistently enriched in patients with PDAC across the 3 countries were identified. CONCLUSIONS: Metagenomics targeting the gut and oral microbiomes can provide a powerful source of biomarkers for identifying individuals with PDAC and their prognoses. The identification of shared gut microbial signatures for PDAC in Asian and European cohorts indicates the presence of robust and global gut microbial biomarkers.

BACKGROUND: Regular visits with healthcare professionals are important for preventing serious complications in patients with diabetes. The purpose of this retrospective cohort study was to clarify whether there was any suppression of physician visits among patients with diabetes during the spread of the novel coronavirus 2019 (COVID-19) in Japan and to assess whether telemedicine contributed to continued visits. METHODS: We used the JMDC Claims database, which contains the monthly claims reported from July 2018 to May 2020 and included 4,595 (type 1) and 123,686 (type 2) patients with diabetes. Using a difference-in-differences analysis, we estimated the changes in the monthly numbers of physician visits or telemedicine per 100 patients in April and May 2020 compared with the same months in 2019. RESULTS: For patients with type 1 diabetes, the estimates for total overall physician visits were -2.53 (95% confidence interval [CI], -4.63 to 0.44) in April and -8.80 (95% CI, -10.85 to -6.74) in May; those for telemedicine visits were 0.71 (95% CI, 0.47-0.96) in April and 0.54 (95% CI, 0.32-0.76) in May. For patients with type 2 diabetes, the estimates for overall physician visits were -2.50 (95% CI, -2.95 to -2.04) in April and -3.74 (95% CI, -4.16 to -3.32) in May; those for telemedicine visits were 1.13 (95% CI, 1.07-1.20) in April and 0.73 (95% CI, 0.68-0.78) in May. CONCLUSION: The COVID-19 pandemic was associated with suppression of physician visits and a slight increase in the utilization of telemedicine among patients with diabetes during April and May 2020.

BACKGROUND: Several epidemiological studies have determined the relationship between diabetes and the incidence and/or prevalence of recently identified comorbid conditions (cancer, periodontal disease, fracture, cognitive impairment, and depression). These relationships may vary by country or race/ethnicity. We aimed to systematically review studies in this field conducted with the Japanese population because such a review in the Japanese population has never been undertaken. METHODS: We conducted systematic literature searches in PubMed and Ichushi-Web databases for studies published until December 2016. Studies comparing the incidence and/or prevalence of the comorbidities among the Japanese population were included. The studies were classified as integrated analyses, cohort studies, case-control studies, or cross-sectional studies. RESULTS: We identified 33 studies (cancer: 17, periodontal disease: 5, fracture: 5, cognitive impairment: 4, and depression: 2). Although several cohort studies and meta-analyses had assessed the development of cancer in diabetes, there was scant epidemiological evidence for the other conditions. Indeed, only one cohort study each had been conducted for periodontal disease, fracture, and cognitive impairment, whereas other evidence was cross-sectional, some of which was induced from baseline characteristic tables of studies designed for other purposes. CONCLUSION: In Japan, there is insufficient evidence about the relationship between diabetes and the incidence/prevalence of periodontal disease, fracture, cognitive impairment, and depression. By contrast, several cohort studies and integrated analyses have been conducted for the relationship with cancer. Further studies should be undertaken to estimate the contribution of diabetes on the incidence/prevalence of comorbidities that may be specific to the Japanese population.

The aim of this study was to evaluate the efficacy and safety of sitagliptin administered to elderly patients with type 2 diabetes mellitus (T2DM) for 1 year as compared with glimepiride. Patients aged ≥60 years with T2DM and inadequately controlled blood glucose were randomly assigned to sitagliptin 50 mg once daily or glimepiride 0.5 mg once daily for 52 weeks. The primary efficacy endpoint was the change in glycated haemoglobin (HbA1c) from baseline to week 52. Secondary efficacy endpoints included self-monitored blood glucose and weight. Safety endpoints were adverse events including hypoglycaemia. Administration of sitagliptin or glimepiride to elderly patients with T2DM resulted in a significant decrease in HbA1c change from baseline. At 52 weeks, the least squares mean difference between the treatments was 0.11% (95% confidence interval [CI] -0.02 to 0.24; P = .087) (1.2 mmol/mol [-0.2 to 2.6]). The upper limit of the CI was below the predefined non-inferiority margin (0.3% [3.3 mmol/mol]), demonstrating non-inferiority of sitagliptin to glimepiride for the primary endpoint. Sitagliptin resulted in a significantly lower incidence rate of non-serious hypoglycaemia than glimepiride during the 52 weeks (4.7% vs 16.1%; P = .002); thus, sitagliptin is a useful therapeutic option for elderly patients with T2DM.

Obesity and insulin resistance, the key features of metabolic syndrome, are closely associated with a state of chronic, low-grade inflammation characterized by abnormal macrophage infiltration into adipose tissues. Although it has been reported that chemokines promote leukocyte migration by activating class IB phosphoinositide-3 kinase (PI3Kγ) in inflammatory states, little is known about the role of PI3Kγ in obesity-induced macrophage infiltration into tissues, systemic inflammation, and the development of insulin resistance. In the present study, we used murine models of both diet-induced and genetically induced obesity to examine the role of PI3Kγ in the accumulation of tissue macrophages and the development of obesity-induced insulin resistance. Mice lacking p110γ (Pik3cg(-/-)), the catalytic subunit of PI3Kγ, exhibited improved systemic insulin sensitivity with enhanced insulin signaling in the tissues of obese animals. In adipose tissues and livers of obese Pik3cg(-/-) mice, the numbers of infiltrated proinflammatory macrophages were markedly reduced, leading to suppression of inflammatory reactions in these tissues. Furthermore, bone marrow-specific deletion and pharmacological blockade of PI3Kγ also ameliorated obesity-induced macrophage infiltration and insulin resistance. These data suggest that PI3Kγ plays a crucial role in the development of both obesity-induced inflammation and systemic insulin resistance and that PI3Kγ can be a therapeutic target for type 2 diabetes.

PURPOSE: Thyrotoxic periodic paralysis (TPP) is characterized by muscle paralysis and significant intracellular potassium movement resulting in hypokalemia. Since TPP is a rare condition, only a few studies have explicated the clinical characteristics of patients with this disease. This study aimed to elucidate the clinical characteristics of patients with TPP by comparing them with those with thyrotoxicosis without paralysis (non-TPP) and sporadic periodic paralysis (SPP). METHODS: This was a single-center retrospective cohort study. Clinical data of patients with hyperthyroidism (n = 62) or periodic paralysis (n = 92) who were emergently admitted to our hospital was extracted from the electronic medical records and analyzed. RESULTS: All patients in the TPP group (15 males and 2 females) had Graves' disease, with 14 being newly diagnosed. The average serum potassium level on admission was 2.3±0.75 mEq/L. No significant correlation was observed among serum potassium level, amount of potassium required for normalization, and thyroid hormone levels. The TPP group showed significantly younger age, higher male ratio and body mass index (BMI), and lower serum potassium and phosphorus levels than the non-TPP group, which comprised 36 patients with Graves' disease. No significant differences were observed between the TPP and SPP (n = 11) groups in terms of age, sex, BMI, serum electrolyte levels, potassium requirement for normalization, and recovery time. MAIN CONCLUSIONS: Considering that most patients with TPP have undiagnosed Graves' disease, distinguishing TPP from SPP based on clinical information and course alone is difficult in emergency settings. Therefore, for early detection and launch of specific treatment of Graves' disease, screening for thyroid hormone and anti-thyroid stimulating hormone receptor antibody levels is necessary when treating patients with periodic paralysis.

Some cases of bronchial asthma are refractory to conventional therapies. As the pathogenesis of bronchial asthma has been clarified, new treatments, such as bronchial thermoplasty and biological drugs, have been developed. Tezepelumab, an anti-thymic stromal lymphopoietin antibody, has been reported to inhibit the exacerbation of severe asthma; however, its adverse effects on glucose metabolism have not yet been reported. We encountered a case of weight gain and worsening glycemic management in a patient with type 2 diabetes and refractory bronchial asthma after the initiation of tezepelumab treatment. It has been reported that the overexpression of thymic stromal lymphopoietin in mice resulted in an enhanced release of free fatty acids from adipose tissues and the liver; thus, the administration of anti-thymic stromal lymphopoietin antibodies in the present case might have caused obesity, fatty liver and lower glucose tolerance.

People with diabetes are encouraged to receive diabetes self-management education and support (DSMES) appropriately. However, in Japan, the implementation rates of DSMES are not known. DSMES implementation rates were calculated using the National Database of claims data, which included nearly all insurance-covered medical procedures. The study enrolled participants who received regular antidiabetic medications between April 2017 and March 2018. The implementation rates of DSMES-related care were calculated by characteristics, visiting medical facilities and prefectures. In 4,465,513 participants receiving antidiabetic medications (men, 57.8%; insulin use, 14.1%), nutrition guidance (5.6%) was the most frequently provided care type. Insulin users and participants visiting Japan Diabetes Society-certified and large medical institutions had higher implementation rates of nutrition guidance. DSMES-related care might not be provided adequately for Japanese people with diabetes. Further studies are needed to develop an optimal diabetes care system.

AIMS/INTRODUCTION: The clinical significance of age-related biomarkers in patients with diabetes has not been fully elucidated. In this study, we aimed to establish models to predict the progression of aging in patients with diabetes using biomarkers. MATERIALS AND METHODS: This single-center, retrospective cohort study included 115 Japanese patients with diabetes aged ≥60 years. Age-related adverse health outcomes were defined as emergency hospitalization, any increase in the level of nursing care certification, admission to a nursing home or death. The associations of age-related biomarker levels (adiponectin, growth differentiation factor 15 [GDF15], C-X-C motif chemokine ligand 9 and apelin) and clinical indicators with age-related adverse health outcomes were evaluated. Factors that predominantly influenced the occurrence of age-related adverse health outcomes were explored using the Cox proportional hazards model. RESULTS: The mean age of the 115 participants was 73 years, 50.6% were men, the mean body mass index and hemoglobin A1c level were 25.3 kg/m2 and 9.79%, respectively. There were 26 age-related adverse health outcomes during the study period (median 1.93, range 0-4.65 years). In a model combining clinical indicators and biomarkers, including the Barthel Index, GDF15 and adiponectin, the occurrence of age-related adverse health outcomes was found to be significantly associated with GDF15 and Barthel Index. The group with both GDF15 and adiponectin levels higher than the median proved to be significantly higher than the group with both lower. CONCLUSIONS: The measurement of GDF15 and adiponectin levels and the Barthel Index might be useful for predicting age-related adverse health outcomes in patients with diabetes.
RESUMO
AIMS/INTRODUCTION: A recent US Food and Drug Administration report highlighted concerns over nitrosamine (7-nitroso-3-(trifluoromethyl)-5,6,7,8-tetrahydro[1,2,4] triazolo-[4,3-a]pyrazine [NTTP]) impurities in sitagliptin, prompting investigations into its safety profile. The present study aimed to determine if the use of NTTP-contaminated sitagliptin, in comparison with other dipeptidyl peptidase-4 (DPP-4) inhibitors, is associated with an increased cancer risk. MATERIALS AND METHODS: This retrospective cohort study secondarily used the National Database of Health Insurance Claims and Specific Health Checkups of Japan, encompassing data on >120 million individuals. The study involved patients who initiated DPP-4 inhibitor therapy (sitagliptin or other DPP-4 inhibitors) and continued its exclusive use for 3 years. Sitagliptin users were compared with other DPP-4 inhibitor users for assessing the occurrence of cancers, as defined by diagnosis codes. Further analyses focused on specific types of cancer, using either diagnosis codes or a combination of diagnosis and procedure codes. We also carried out various sensitivity analyses, including those with different exposure periods. RESULTS: Sitagliptin users (149,120 patients, 388,356 person-years) experienced 9,643 cancer incidences (2,483.0/100,000 person-years) versus 12,621 incidences (2,504.4/100,000 person-years) among other DPP-4 inhibitor users (199,860 patients, 503,952 person-years), yielding a minimal difference (incidence rate ratio 0.99, 95% confidence interval 0.97-1.02). A multiple Cox proportional hazards model showed no significant association between sitagliptin use and overall cancer incidence (hazard ratio 1.01, 95% confidence interval 0.98-1.04). Findings were also consistent across cancer types and sensitivity analyses. CONCLUSIONS: We observed no evidence to suggest an increased cancer risk among patients prescribed NTTP-contaminated sitagliptin, although continued investigation is needed.
RESUMO
AIMS: To understand glucagon-like peptide-1 receptor agonist (GLP-1RA) use in patients with type 2 diabetes (T2D) in Japan. METHODS: Characteristics of people receiving GLP-1RAs between 2016 and 2020 in the J-DREAMS database were investigated. Changes in HbA1c, body weight (BW), body mass index (BMI), and proportion reaching HbA1c targets were analysed in GLP-1RA-naïve patients 6-24 months after GLP-1RA initiation. RESULTS: The proportion of patients with GLP-1RA prescriptions increased from 3.6% to 9.6% during 2016-2020. Among GLP-1RA-naïve patients (n = 569), HbA1c reduced -|0.6% (95% confidence interval [CI] -0.7, -0.5; -6 mmol/mol [95% CI -7, -5]) 6 months after treatment initiation and stabilised until 24 months (P < 0.001); mean BW and BMI reduced -1.05 kg (95% CI -1.31, -0.80) and -0.43 kg/m2 (95% CI -0.53, -0.32), respectively, at 6 months (P < 0.001). The proportion of GLP-1RA-naïve patients with HbA1c < 7.0% (<53 mmol/mol) and <8.0% (<64 mmol/mol) increased from 16% to 27% and 43% to 65%, respectively, and an HbA1c reduction of ≥1.0% (≥11 mmol/mol) was observed in 33% of patients after 6 months (P < 0.001). CONCLUSIONS: This study shows increased GLP-1RA prescriptions over 5 years. HbA1c and BW reduced 6 months after GLP-1RA initiation in patients with T2D in a Japanese real-world setting.

AIMS/INTRODUCTION: Regular screening for diabetic retinopathy is essential. This study aimed to show the process and current situation of diabetic retinopathy screening prescribed by physicians (internists) and ophthalmologists for Japanese patients with diabetes. MATERIALS AND METHODS: This retrospective cohort study used data from the Japanese National Database of Insurance Claims between April 2016 and March 2018. Ophthalmology visits and fundus examinations are defined using specific medical procedure codes. The proportion of ophthalmology visits for patients with diabetic medication and for fundus examination among those who visited ophthalmologists was calculated in the fiscal year 2017. A modified Poisson regression analysis was carried out to identify factors associated with retinopathy screening. Similarly, quality indicators by prefectures were also calculated. RESULTS: Among 4,408,585 patients receiving diabetic medications (57.8% men, 14.1% insulin use), 47.4% visited the ophthalmology department and 96.9% of those underwent fundus examination. Regression analysis showed that female sex, older age, insulin use, medical facilities with Japan Diabetes Society certification and large medical facilities were predictors of fundus examination. By prefecture, the ophthalmology consultation rate and the fundus examination ranged 38.5-51.0% and 92.1-98.7%, respectively. CONCLUSIONS: Less than half of the patients who were prescribed antidiabetic medication by their physicians visited an ophthalmologist. However, most of the patients who visited an ophthalmologist had a fundus examination carried out. A similar tendency was noted for each prefecture. It is essential to reaffirm the necessity of recommending ophthalmologic examinations to physicians and healthcare professionals who care for patients with diabetes.

We aimed to estimate the cumulative incidence of treatment-requiring diabetic retinopathy since clinical diagnosis of diabetes based on the course of diagnosis in a retrospective cohort study using Japan's medical claims and health checkup data (JMDC Claims Database; 2009-2020). We included patients whose diabetes was first diagnosed at medical facilities (hospitals/clinics). We grouped them by health checkup participation before diagnosis, health checkup results, and antidiabetic medication promptly after the diagnosis. The incidence of treatment-requiring diabetic retinopathy (laser photocoagulation, intraocular injection, or vitrectomy) was compared among the groups. Of 126,696 patients, those who started an antidiabetic medication promptly after diabetes diagnosis without a recent health checkup faced the highest risk of treatment-requiring diabetic retinopathy (1-/5-year cumulative incidence: 3.1%/6.0%). This increased risk was consistently observed across various analyses, including the Cox proportional hazard model, sensitivity analysis restricting to those with an eye examination, and sensitivity analysis using vitrectomy as the outcome. Among patients with HbA1c ≥ 6.5% at recent health checkups, those who promptly started an antidiabetic medication had a higher risk (1.4%/3.8%) than those who did not (0.7%/2.7%). Taking the information about the course of diabetes diagnosis is important to manage risk stratification for diabetic retinopathy appropriately.

Aim: To cross-sectionally and longitudinally investigate the association between tumor markers (Cancer embryonic antigen (CEA) Carbohydrate antigen 19-9 (CA19-9)) and malignancies in type 2 diabetes patients without evidence of malignancy. Materials and Methods: The study included 707 patients admitted for the treatment of diabetes from 1 August 2010 to 1 September 2018. Serum CEA and CA19-9 levels were measured for screening of malignancies at admission. Abdominal ultrasonography, computed tomography, and endoscopy were performed for close examination. The percentage of patients diagnosed with malignancy was calculated, and among those without malignancy, the incidence of malignancies was examined after discharge. Results: A total of 26 patients (3.7%) were newly diagnosed with malignancy during hospitalization. The optimal cut-off value of CEA and CA19-9 by receiver operating characteristic analysis was 5.0 ng/mL and 75 U/mL, and their positive predictive values (PPV) were 8.7% and 22.5%, respectively. The addition of CA19-9 to age, smoking status, body mass index, and glycated hemoglobin significantly improved classification performance for malignancy using net reclassification improvement (0.682, 95% CI 0.256-1.107) and integrated discrimination improvement (0.150, 95% CI 0.007-0.294). Among 681 patients without malignancies during hospitalization, 30 patients (4.4%) developed malignancies during an average follow-up of 3.9 years. CA19-9 (hazard ratio: 1.005, 95% CI: 1.003-1.008) was associated with the development of malignancies. Conclusions: PPV of serum CEA and CA19-9 for detecting malignancy was high in type 2 diabetes patients with poor glycemic control. Measuring CA19-9 was found to be valuable to cross-sectionally and longitudinally detect malignancies. Supplementary Information: The online version contains supplementary material available at 10.1007/s13340-022-00594-x.
RESUMO
AIMS/INTRODUCTION: We aimed to examine the proportion of subsequent clinic visits for persons screened as having hyperglycemia based on glycated hemoglobin (HbA1c) levels at screening and the presence/absence of hyperglycemia at health checkups before 1 year of the screening among those without previous diabetes-related medical care and attending regular clinic visits. MATERIALS AND METHODS: This retrospective cohort study used the 2016-2020 data of Japanese health checkups and claims. The study analyzed 8,834 adult beneficiaries aged 20-59 years without regular clinic visits who had never received diabetes-related medical care and whose recent health checkups showed hyperglycemia. The rates of 6-month subsequent clinic visits after health checkups were evaluated according to HbA1c levels and the presence/absence of hyperglycemia at checkups a year before. RESULTS: The overall clinic visit rate was 21.0%. The HbA1c-specific rates were 17.0, 26.7, 25.4 and 28.4% for <7.0, 7.0-7.4, 7.5-7.9 and ≥8.0% (64 mmol/mol), respectively. Persons with hyperglycemia at a previous screening had lower clinic visit rates than those without hyperglycemia, particularly in the HbA1c category of <7.0% (14.4% vs 18.5%; P < 0.001) and 7.0-7.4% (23.6% vs 35.1%; P < 0.001). CONCLUSIONS: The overall rate of subsequent clinic visits among those without previous regular clinic visits was <30%, including for participants with HbA1c ≥8.0%. Persons with previously detected hyperglycemia had lower clinic visit rates, despite requiring more health counseling. Our findings might be useful for designing a tailored approach to encourage high-risk individuals to seek diabetes care through clinic visits.

AIMS/INTRODUCTION: To assess the association of undiagnosed diabetes mellitus and its acute-to-chronic glycemic ratio with clinical outcome in patients hospitalized with coronavirus disease 2019 (COVID-19) using a large-scale nationwide registry in Japan. MATERIALS AND METHODS: Overall, 4,747 patients were included between July 2021 and January 2022. We evaluated blood glucose and glycated hemoglobin levels at admission, and calculated the acute-to-chronic glycemic ratio for each non-diabetes mellitus, undiagnosed diabetes mellitus and pre-existing diabetes mellitus group. The primary composite outcome comprised in-hospital mortality, invasive mechanical ventilation, extracorporeal membrane oxygenation support, intensive care unit admission and transfer to a more advanced medical facility. RESULTS: Compared with the non-diabetes mellitus group, the undiagnosed diabetes mellitus group was significantly associated with a worse COVID-19 outcome (odds ratio 2.18, 95% confidence interval 1.50-3.18). In patients with undiagnosed diabetes mellitus, the 3rd tertile of the acute-to-chronic glycemic ratio was linked with a worse COVID-19 outcome compared with the 1st tertile (odds ratio 3.33, 95% confidence interval 1.43-7.77), whereas glycated hemoglobin levels were not; among patients with pre-existing diabetes mellitus, glycated hemoglobin levels were linked with a worse outcome. CONCLUSIONS: Among patients with undiagnosed diabetes mellitus with COVID-19, the magnitude of elevation of blood glucose from chronic to acute levels is associated with worse outcomes.

Patients with human immunodeficiency virus (HIV) infection receiving antiretroviral therapy can develop autoimmune diseases, referred to as immune-inflammatory reconstitution syndrome. Nevertheless, only a few reports on the onset of type 1 diabetes as immune-inflammatory reconstitution syndrome are available. A 40-year-old Japanese man with HIV infection was initiated with antiretroviral therapy at the age of 29 years. He developed Graves' disease at 35 years and diabetes, with a hemoglobin A1c of 6.5%, and maintained insulin secretion at 38 years. His antiglutamic acid decarboxylase antibody level was >2,000 U/mL, and he was diagnosed with slowly progressive type 1 diabetes. At the age of 40 years, he was admitted to our hospital with diabetic ketosis. We retrospectively assayed his stored plasma samples for thyroid-stimulating hormone receptor antibody and antiglutamic acid decarboxylase antibody, which showed positive conversion after initiating antiretroviral therapy, suggesting that Graves' disease and type 1 diabetes developed as a probable result of immune-inflammatory reconstitution syndrome.

Summary: A 47-year-old man was diagnosed with a left adrenal incidentaloma at 40 years of age. The tumor had irregular margins and grew from 18 mm to 30 mm in maximum diameter over 7 years. On computed tomography scan, the mass appeared to localize within the tip of the lateral limb of the left adrenal gland, and between the left adrenal gland and the posterior wall of the stomach. The plasma corticotropin and cortisol concentrations and the 24-h urine fractionated metanephrine levels were normal. 123I-metaiodobenzylguanidine scintigraphy showed tumor avidity consistent with a hormonally inactive pheochromocytoma. A laparoscopic left adrenalectomy was performed; however, no tumor was present in the resected specimen. Abdominal computed tomography postoperatively showed that the tumor remained intact and appeared to connect to the posterior wall of the stomach. A laparotomy was performed and the tumor was removed. The tumor was localized to the intraperitoneal space and isolated from the posterior wall of the stomach. The pathological diagnosis was a gastrointestinal stromal tumor. Clinicians need to be aware of the limitations of diagnostic imaging studies in diagnosing non-functioning adrenal incidentalomas, which require a pathological analysis for the final diagnosis. Moreover, clinicians need to provide patients with sufficient informed consent when deciding on treatment strategies. Learning points: Anatomic structures and tumors that develop in neighboring tissues to the adrenal glands may be confused with primary adrenal tumors. 123I- metaiodobenzylguanidine (MIBG) scintigraphy is specific for diagnosing pheochromocytomas and paragangliomas; however, it has been reported that 123I-MIBG may accumulate in neuroendocrine tumors as well as other tumors. Clinicians should recognize the limitations of imaging studies and the uncertainty of an imaging-based preoperative diagnosis.
