SARS-CoV-2 infection impairs the insulin/IGF signaling pathway in the lung, liver, adipose tissue, and pancreatic cells via IRF1.

BACKGROUND: COVID-19 can cause multiple organ damages as well as metabolic abnormalities such as hyperglycemia, insulin resistance, and new onset of diabetes. The insulin/IGF signaling pathway plays an important role in regulating energy metabolism and cell survival, but little is known about the impact of SARS-CoV-2 infection. The aim of this work was to investigate whether SARS-CoV-2 infection impairs the insulin/IGF signaling pathway in the host cell/tissue, and if so, the potential mechanism and association with COVID-19 pathology. METHODS: To determine the impact of SARS-CoV-2 on insulin/IGF signaling pathway, we utilized transcriptome datasets of SARS-CoV-2 infected cells and tissues from public repositories for a wide range of high-throughput gene expression data: autopsy lungs from COVID-19 patients compared to the control from non-COVID-19 patients; lungs from a human ACE2 transgenic mouse infected with SARS-CoV-2 compared to the control infected with mock; human pluripotent stem cell (hPSC)-derived liver organoids infected with SARS-CoV-2; adipose tissues from a mouse model of COVID-19 overexpressing human ACE2 via adeno-associated virus serotype 9 (AAV9) compared to the control GFP after SARS-CoV-2 infection; iPS-derived human pancreatic cells infected with SARS-CoV-2 compared to the mock control. Gain and loss of IRF1 function models were established in HEK293T and/or Calu3 cells to evaluate the impact on insulin signaling. To understand the mechanistic regulation and relevance with COVID-19 risk factors, such as older age, male sex, obesity, and diabetes, several transcriptomes of human respiratory, metabolic, and endocrine cells and tissue were analyzed. To estimate the association with COVID-19 severity, whole blood transcriptomes of critical patients with COVID-19 compared to those of hospitalized noncritical patients with COVID-19. RESULTS: We found that SARS-CoV-2 infection impaired insulin/IGF signaling pathway genes, such as IRS, PI3K, AKT, mTOR, and MAPK, in the host lung, liver, adipose tissue, and pancreatic cells. The impairments were attributed to interferon regulatory factor 1 (IRF1), and its gene expression was highly relevant to risk factors for severe COVID-19; increased with aging in the lung, specifically in men; augmented by obese and diabetic conditions in liver, adipose tissue, and pancreatic islets. IRF1 activation was significantly associated with the impaired insulin signaling in human cells. IRF1 intron variant rs17622656-A, which was previously reported to be associated with COVID-19 prevalence, increased the IRF1 gene expression in human tissue and was frequently found in American and European population. Critical patients with COVID-19 exhibited higher IRF1 and lower insulin/IGF signaling pathway genes in the whole blood compared to hospitalized noncritical patients. Hormonal interventions, such as dihydrotestosterone and dexamethasone, ameliorated the pathological traits in SARS-CoV-2 infectable cells and tissues. CONCLUSIONS: The present study provides the first scientific evidence that SARS-CoV-2 infection impairs the insulin/IGF signaling pathway in respiratory, metabolic, and endocrine cells and tissues. This feature likely contributes to COVID-19 severity with cell/tissue damage and metabolic abnormalities, which may be exacerbated in older, male, obese, or diabetic patients.

GRP78, a Novel Host Factor for SARS-CoV-2: The Emerging Roles in COVID-19 Related to Metabolic Risk Factors.

The outbreak of coronavirus disease 19 (COVID-19), caused by the infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has resulted in an unprecedented amount of infection cases and deaths, leading to the global health crisis. Despite many research efforts, our understanding of COVID-19 remains elusive. Recent studies have suggested that cell surface glucose-regulated protein 78 (GRP78) acts as a host co-receptor for SARS-CoV-2 infection and is related to COVID-19 risks, such as older age, obesity, and diabetes. Given its significance in a wide range of biological processes, such as protein homeostasis and cellular signaling, GRP78 might also play an important role in various stages of the viral life cycle and pathology of SARS-CoV-2. In this perspective, we explore the emerging and potential roles of GRP78 in SARS-CoV-2 infection. Additionally, we discuss the association with COVID-19 risks and symptoms. We hope this review article will be helpful to understand COVID-19 pathology and promote attention and study of GRP78 from many clinical and basic research fields.

Possible Involvement of Adipose Tissue in Patients With Older Age, Obesity, and Diabetes With SARS-CoV-2 Infection (COVID-19) via GRP78 (BIP/HSPA5): Significance of Hyperinsulinemia Management in COVID-19.

Aging, obesity, and diabetes are major risk factors for the severe progression and outcome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (coronavirus disease 2019 [COVID-19]), but the underlying mechanism is not yet fully understood. In this study, we found that the SARS-CoV-2 spike protein physically interacts with cell surface GRP78, which promotes the binding to and accumulation in ACE2-expressing cells. GRP78 was highly expressed in adipose tissue and increased in humans and mice with older age, obesity, and diabetes. The overexpression of GRP78 was attributed to hyperinsulinemia in adipocytes, which was in part mediated by the stress-responsive transcription factor XBP-1s. Management of hyperinsulinemia by pharmacological approaches, including metformin, sodium-glucose cotransporter 2 inhibitor, or ß3-adrenergic receptor agonist, decreased GRP78 gene expression in adipose tissue. Environmental interventions, including exercise, calorie restriction, fasting, or cold exposure, reduced the gene expression of GRP78 in adipose tissue. This study provides scientific evidence for the role of GRP78 as a binding partner of the SARS-CoV-2 spike protein and ACE2, which might be related to the severe progression and outcome of COVID-19 in patients with older age, obesity, and diabetes. The management of hyperinsulinemia and the related GRP78 expression could be a therapeutic or preventative target.

HbA1c <7.0% 6 Months after Initiation of Second-Line Therapy in Patients with Uncontrolled Type 2 Diabetes Is Associated with Good Glycemic Control at 3 Years: The DISCOVER Study

Background: DISCOVER is a 3-year, observational study of people with type 2 diabetes (T2D) initiating a second-line glucose-lowering therapy in 38 countries. We assessed glycemic control after 3 years in participants with HbA1c ≥ 9.0% at baseline. Methods: Factors associated with an increased likelihood of having HbA1c < 7.0% after 3 years were assessed using a hierarchical logistic regression model. Results: Of 14 691 DISCOVER participants from 37 countries, 2233 (15.2%) had sufficient HbA1c data and HbA1c ≥ 9.0% at baseline. The majority of participants were men (58.0%), and the mean age was 54.4 years (SD: 11.2 years). The mean HbA1c at baseline was 10.4% (SD: 1.4%). After 3 years, 626 participants (28.0%) had HbA1c < 7.0% and 438 (19.6%) had HbA1c ≥ 9.0%. Time since T2D diagnosis ≥ 10 years (vs.< 5 years) was associated with a decreased likelihood of having HbA1c < 7.0% at 3 years (Figure). Second-line therapy with two or more glucose-lowering drugs (vs. insulin) and having HbA1c < 7.0% at 6 months (24.2% of patients) were associated with an increased likelihood of having HbA1c < 7.0% at 3 years. Conclusions: Less than a third of participants with HbA1c ≥ 9.0% at initiation of second-line therapy reached HbA1c < 7.0% after 3 years. Early glycemic control (HbA1c < 7.0% at 6 months) was a key factor associated with attaining this target. Disclosure: F.

Effect of Tofogliflozin on Carotid Intima-Media Thickness in Patients with Type 2 Diabetes: Results from the Prospective, Randomized, Open-Label, Parallel-Group Comparative UTOPIA Trial

Background: This study aimed to investigate the preventive effects of tofogliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, on atherosclerosis progression in type 2 diabetes (T2DM) patients without apparent cardiovascular disease (CVD) by monitoring carotid intima-media thickness (IMT). Methods: This prospective, randomized, open-label, blinded-endpoint, multicenter, parallel-group, comparative study included 340 subjects with T2DM but no history of apparent CVD recruited at 24 clinical units. Subjects were randomly allocated to either the tofogliflozin treatment group (n=169) or conventional treatment group using drugs other than SGLT2 inhibitors (n=171). Primary outcomes were changes in mean and maximum common carotid IMT measured by echography during a 104-week treatment period. Findings: Although the mean IMT of the common carotid artery (mean-IMT-CCA), along with the right and left maximum IMT of the CCA (max-IMT-CCA), statistically significantly declined in both the tofogliflozin (-0.132 mm, SE 0.007;-0.163 mm, SE 0.013;-0.170 mm, SE 0.020;respectively) and the control group (-0·140 mm, SE 0·006;-0·190 mm, SE 0·012;-0·190 mm, SE 0·020;respectively), no significant difference was observed between the two groups. Relative to the control treatment effects, tofogliflozin statistically significantly reduced the HbA1c, blood glucose level, body weight/body mass index, abdominal circumference, and systolic blood pressure, and statistically significantly increased the HDL-C. Interpretation: A tofogliflozin treatment regimen of 104 weeks was not associated with improved inhibition of carotid wall thickening in T2DM patients without apparent CVD, as compared to the effect of the control treatment.

Quality of Life in People with Type 2 Diabetes following Initiation of Second-Line Therapy: DISCOVER

Background: Symptom relief, prolonging survival and avoiding complications are key goals in treating type 2 diabetes (T2D), but health-related quality of life (HRQoL) may be as or more important to patients. We used DISCOVER, a global observational study of people with T2D initiating a second-line glucose-lowering therapy, to examine factors associated with HRQoL over 3 years of follow-up. Methods: HRQoL was assessed using the 36-item Short-Form Health Survey (SF-36) v2 mental and physical component summary (MCS;PCS) scores (higher scores = better HRQoL) and the Hypoglycemia Fear Survey II (HFS-II;higher scores = greater fear). Factors associated with HRQoL over time were assessed using longitudinal multivariable regression models. Results: Of 14 691 DISCOVER patients from 37 countries, baseline and ≥ 1 follow-up MCS, PCS and HFS-II scores were available for 7880, 7854 and 5387 patients, respectively. Over time, SF-36 scores decreased (change per 6 months from baseline: MCS −0.04 [95% CI: −0.05 to −0.04];PCS −0.03 [95% CI: −0.03 to −0.02]), and HFS-II scores increased (change: 0.10 [95% CI: 0.09 to 0.12]). Many factors were associated with HRQoL (Table). Conclusions: HRQoL worsened during follow-up. Patient-, disease- and treatment-related factors were associated with HRQoL differences. Assessing factors associated with HRQoL over time may inform interventions to improve this important outcome. Disclosure: A. Nicolucci: Consultant;Self;AstraZeneca. H. Chen: None. A.

Lifestyle changes and their impact on glycemic control and weight control in patients with diabetes during the coronavirus disease 2019 pandemic in Japan.

AIMS/INTRODUCTION: This study aimed to reveal lifestyle changes and their impact on glycemic control and weight control in patients with diabetes during the coronavirus disease 2019 (COVID-19) pandemic in Japan. MATERIALS AND METHODS: We retrospectively analyzed 1,402 outpatients with diabetes at a clinic in Osaka, Japan, who responded to an interview sheet regarding lifestyle changes during the COVID-19 pandemic between 28 March and 30 May 2020. The association of lifestyle changes with hemoglobin A1c (HbA1c) and weight changes from February to May 2020 was investigated using the linear regression model. We also investigated the association with clinically important change of HbA1c (by ≥0.3%) and bodyweight (by ≥3%), using the cumulative link model. RESULTS: Leisure time and other outside physical activities were decreased in one-quarter of patients during the COVID-19 pandemic, whereas the amount of meals and snacks was decreased and increased in approximately 10%, respectively. The change in leisure time physical activities was inversely associated with HbA1c and weight changes, whereas the quantitative change of meals with the decline in eating out and that of snacks were positively associated with HbA1c and weight changes (all P < 0.05). The quantitative change of meals without the decline in eating out was also positively associated with weight change (P = 0.012). The cumulative link model for clinically important HbA1c and weight change showed broadly similar associations, except for that between snacks and bodyweight (P = 0.15). CONCLUSIONS: A considerable number of outpatients with diabetes experienced lifestyle changes during the COVID-19 pandemic. The lifestyle changes were associated with HbA1c and weight changes.
