Abstract
BACKGROUND Coronary and thoracic aortic calcification was associated with stroke, coronary heart, and peripheral vascular disease. Hepatitis C virus (HCV) infection is significantly associated with insulin resistance, diabetes mellitus and hepatic steatosis. We aimed to investigate the relationship between HCV infection and coronary, thoracic aortic atherosclerosis. MATERIALS AND METHODS Calcification was detected by chest computed tomography and defined as any Agatston score greater than zero. Metabolic syndrome was based on the modified Adult Treatment Panel III criteria. Fibrosis-4 (FIB-4) and AST-to-platelet ratio (APRI) was calculated. The anti-HCV signal-to-cutoff (S/CO) ratio was determined by the third generation ELISA kit. Atherosclerosis risk was estimated by using multiple logistic regression modeling. RESULTS Being positive for both metabolic syndrome and HCV infection (OR = 2.65, 95% CI: 1.26-5.59, p = 0.007), negative for metabolic syndrome and positive for HCV infection (OR = 2.75, 95% CI: 1.48-5.30, p = 0.001), and positive for metabolic syndrome and negative for HCV infection (OR = 2.42, 95% CI: 1.92-3.07, p < 0.001) were associated with atherosclerosis compared with being negative for both metabolic syndrome and HCV infection (Ptrend< 0.001). HCV infection with liver fibrosis (HCVFIB4>1.4; OR = 2.16, 95% CI: 1.22-3.82, p = 0.008), or (HCVAPRI>0.5; OR = 3.40, 95% CI: 1.28-9.06, p = 0.014) and elevated anti-HCV S/CO ratio (anti-HCVS/CO>10.0; OR = 1.72, 95% CI: 1.01-2.93, p = 0.045) was associated with atherosclerosis. CONCLUSIONS HCV infection with metabolic syndrome, liver fibrosis and elevated anti-HCV S/CO ratio was associated with atherosclerosis.

Regulatory mechanisms underlying endoplasmic reticulum stress involvement in the development of gestational diabetes mellitus entail the CHOP-PPARα-NF-κB pathway. Placenta 2023; 142:46-55. [PMID: 37639950 DOI: 10.1016/j.placenta.2023.08.070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 07/25/2023] [Accepted: 08/22/2023] [Indexed: 08/31/2023]
Abstract
OBJECTIVE We investigated the proinflammatory functions of endoplasmic reticulum stress and peroxisome proliferator-activated receptor α (PPARα) in the development of gestational diabetes mellitus (GDM) and their relationship in regulating inflammation in GDM. METHODS This study was performed on placentas of normal pregnant women, women with GDM, and HTR8 cells. Transmission electron microscopy, immunohistochemistry, Western blot analysis, and RT-PCR were performed to analyze ERS and PPARα expression on both normal and GDM pregnancy placentas. ELISA was performed to analyze inflammatory biomarkers. To generate models of the GDM-like state, placentas of normal pregnancy were treated with LPS and polyinosinic-polycytidylic acid (poly [I:C]). TG, CHOP plasmid, and CHOP siRNA were assessed as to their regulation of HTR8 cells to discern the relationship between ERS and PPARα in regulating the inflammation associated with GDM. RESULTS ERS was elevated in GDM placentas, induced the secretion of IL-6 and TNF-α, and attenuated the expression of GLUT-4. PPARα was diminished in GDM placentas and inhibited the inflammatory responses via the NF-κB nuclear-transport process. 4-PBA reduced CHOP and augmented PPARα, and it decreased IL-6 and TNF-α in our GDM-like explant. However, with both 4-PBA and MK886 treatment, we noted no significant difference in CHOP expression. The level of PPARα was reduced, and that of NF-κB p65 in the nucleus was elevated with TG treatment in the HTR8/Svneo. Knockdown of CHOP increased PPARα and reduced NF-κB p65, while expression of PPARα declined, and that of NF-κB p65 rose with the application of CHOP when HTR8 cells were treated with TG. CONCLUSIONS ERS contributes to the pathophysiology of GDM in pregnancy via the CHOP-PPARα-NF-κB-signalling pathway by inducing aberrant activation of inflammation and insulin resistance.

Inter-Day Variation in the Fasting Plasma Lipopolysaccharide Concentration in the Morning Is Associated with Inter-Day Variation in Appetite in Japanese Males: A Short-Term Cohort Study. Metabolites 2023; 13:metabo13030395. [PMID: 36984835 PMCID: PMC10053071 DOI: 10.3390/metabo13030395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/03/2023] [Accepted: 03/06/2023] [Indexed: 03/11/2023] Open
Abstract
Injection of lipopolysaccharide (LPS), a product of gut bacteria, into the blood increases blood triglycerides and cortisol, an appetite-stimulating hormone. Meanwhile, small amounts of LPS derived from gut bacteria are thought to enter the bloodstream from the gut in daily basis. This study aimed to investigate the effect of LPS influx on appetite or lipid metabolism in humans in everyday life. We measured the fasting plasma LPS concentration before breakfast and the corresponding days’ appetite and fat-burning markers for 10 days in four Japanese males (28–31 years) and analyzed the correlation of their inter-day variation. The LPS concentration was negatively correlated with fullness, and positively correlated with the carbohydrate intake. Against our hypothesis, the LPS concentration was positively correlated with the fasting breath acetone concentration, a fat-burning marker. There was a positive correlation between the LPS concentration and fasting body mass index (BMI), but the inter-day variation in BMI was slight. The results suggest that the LPS influx in everyday life is at least associated with appetite in the day.

Abstract
Hepatitis C virus (HCV) is a common cause of liver disease and is associated with various extrahepatic manifestations (EHMs). This mini-review outlines the currently available treatments for HCV infection and their prognostic effect on hepatic manifestations and EHMs. Direct-acting antiviral (DAA) regimens are considered pan-genotypic as they achieve a sustained virological response (SVR) > 85% after 12 wk through all the major HCV genotypes, with high percentages of SVR even in advanced fibrosis and cirrhosis. The risk factors for DAA failure include old males, cirrhosis, and the presence of resistance-associated substitutions (RAS) in the region targeted by the received DAAs. The effectiveness of DAA regimens is reduced in HCV genotype 3 with baseline RAS like A30K, Y93H, and P53del. Moreover, the European Association for the Study of the Liver recommended the identification of baseline RAS for HCV genotype 1a. The higher rate of hepatocellular carcinoma (HCC) after DAA therapy may be related to the fact that DAA regimens are offered to patients with advanced liver fibrosis and cirrhosis, where interferon was contraindicated to those patients. The change in the growth of pre-existing subclinical, undetectable HCC upon DAA treatment might be also a cause. Furthermore, after DAA therapy, the T cell-dependent immune response is much weaker upon HCV clearance, and the down-regulation of TNF-α or the elevated neutrophil to lymphocyte ratio might increase the risk of HCC. DAAs can result in reactivation of hepatitis B virus (HBV) in HCV co-infected patients. DAAs are effective in treating HCV-associated mixed cryoglobulinemia, with clinical and immunological responses, and have rapid and high effectiveness in thrombocytopenia. DAAs improve insulin resistance in 90% of patients, increase glomerular filtration rate, and decrease proteinuria, hematuria and articular manifestations. HCV clearance by DAAs allows a significant improvement in atherosclerosis and metabolic and immunological conditions, with a reduction of major cardiovascular events. They also improve physical function, fatigue, cognitive impairment, and quality of life. Early therapeutic approach with DAAs is recommended as it cure many of the EHMs that are still in a reversible stage and can prevent others that can develop due to delayed treatment.

Abstract
Hepatitis C virus (HCV), a global health concern, has been linked to various hepatic and extrahepatic deleterious manifestations. Several observational studies have either supported the increased likelihood of coronary and carotid atherosclerosis after infection with HCV or refuted it. To date, there has been no clear consensus to support either train of thought, as randomized, controlled clinical trials have not been completed. In this review, we first discuss articles that support the notion that HCV infection leads to increased plaque formation due to systemic inflammation and then focus on articles that refute this idea. From the literature, we do know that both inflammatory and lipid processes play a role in plaque formation, and thus both components are important in the successful treatment of atherosclerosis. Based on our review of the literature, we do believe that HCV-infected individuals are at an increased risk for more severe coronary artery disease than their healthy counterparts. Although there is no irrefutable evidence that links HCV infection with plaque formation and/or rupture, cardioprotective measures should be taken to reduce poor health outcomes, especially in those individuals who are already at risk of coronary disease.

Abstract
End-stage liver disease (ESLD) is a rare but often fatal complication of nonalcoholic fatty liver disease (NAFLD). In NAFLD, insulin resistance, which is clinically defined as the impairment of insulin's ability to maintain glucose homeostasis, is associated with perturbations in insulin action that promote triglyceride accumulation, such as increasing de novo lipogenesis. However, the key step in the development of ESLD is not the accumulation of triglycerides, but hepatocyte injury. Whether and how triglycerides promote hepatocyte injury remains unclear. Consequently, it is difficult to predict whether drugs designed to reduce hepatic triglycerides will prevent the most important complications of NAFLD.

Abstract
Endotoxemia is a severe inflammation response induced by infection especially bacterial endotoxin translocation, which severely increases mortality in combination with acute colon injury. Bromodomain-containing protein 4 (BRD4) is an important Bromo and Extra-Terminal (BET) protein to participate in inflammatory responses. However, it is still unknown about the specific connection between BRD4 and inflammation-related pyroptosis in endotoxemia colon. Here, through evaluating the mucous morphology and the expression of tight junction proteins such as occludin and ZO1, we found the upregulation of BRD4 in damaged colon with poor tight junction in an endotoxemia mouse model induced by lipopolysaccharides (LPS). Firstly, the BRD4 inhibitor JQ1 was used to effectively protect colon tight junction in endotoxemia. As detected, high levels of pro-inflammation cytokines IL6, IL1β and IL18 in endotoxemia colon were reversed by JQ1 pretreatment. In addition, JQ1 injection reduced endotoxemia-induced elevation of the phosphorylated NF κB and NLRP3/ASC/caspase 1 inflammasome complex in colon injury. Furthermore, activated pyroptosis markers gasdermins in endotoxemia colon were also blocked by JQ1 pretreatment. Together, our data indicate that BRD4 plays a critical role in regulating pyroptosis-related colon injury induced by LPS, and JQ1 as a BRD4 inhibitors can effectively protect colon from endotoxemia-induced inflammation injury.

Abstract
Despite the availability of effective treatments, hepatitis C virus (HCV) still remains a threat to public health. HCV is capable to trigger, behind liver damage, extrahepatic manifestations, including cardiovascular disease and type 2 diabetes (T2DM). A close association has been reported between HCV infection and cardiovascular disease due to imbalances in metabolic pathways and chronic inflammation. HCV through both direct and indirect mechanisms causes a higher incidence of ischemic stroke, acute coronary syndrome, heart failure and peripheral arterial disease. In addition, a higher risk of death from cardiovascular events has been showed in HCV patients. Insulin resistance is a hallmark of HCV infection and represents the link between HCV and T2DM, which is one of the most frequent HCV-associated extrahepatic manifestations. The pathological basis of the increased risk of T2DM in HCV infection is provided by the alterations of the molecular mechanisms of IR induced both by the direct effects of the HCV proteins, and by the indirect effects mediated by chronic inflammation, oxidative stress and hepatic steatosis. T2DM increases the risk of compensated and decompensate cirrhosis and hepatocellular carcinoma as well as increases the risk of cardiovascular disease, lower limb amputation and end stage renal disease. Current evidence suggests that HCV eradication reduces the incidence and mortality of cardiovascular disease and T2DM, further underling the importance of public health strategies for eradication the infection. The aim of this review was to update evidence and management of interaction between HCV, cardiovascular disease, and T2DM in the era of DAA treatment.

Abstract
BACKGROUND Liver is one of the first organs to be exposed to reactive oxygen species (ROS). But the data about the levels of redox homeostasis parameters in the patients with liver cirrhosis (LC) are contradictory. We hypothesized that the levels of malondialdehyde and catalase should change in accordance with the LC severity causing the endothelial dysfunction. METHODS In a randomized way with the preliminary stratification by the presence of LC 81 patients and 20 healthy volunteers were examined. To determine the contents of catalase, malondialdehyde, cyclic guanosine monophosphate, endothelin-1, renin, aldosterone, natriuretic peptide, the routine standardized methods were used. RESULTS Patients with LC revealed the statistically significant increase of malondialdehyde and decrease of catalase levels in parallel with the increase of cyclic guanosine monophosphate, endothelin-1, renin, aldosterone, natriuretic peptide contents and disease course worsening according to the Child-Pugh criteria. It testifies the huge oxidative stress impact on the organism. Initially, at the stage of LC compensation, it slightly stimulates the activation of antioxidant system, followed by its gradual suppression at the stages of sub- and decompensation. Disorders of redox homeostasis lead to the endothelial dysfunction that becomes the background of extrahepatic comorbid disorders. CONCLUSIONS Cirrhotic patients have significant abnormalities in the redox homeostasis, which become the background of the endothelial dysfunction - common trigger mechanism for the syntrophic comorbid diseases and early pathophysiologic symptom of the unfavorable prognosis for such patients.

Abstract
Fatty liver haemorrhagic syndrome (FLHS) is a widespread metabolic disease in laying hens that causes a decrease in egg production and even death. Insulin resistance is a major contributor to the pathogenesis of nonalcoholic fatty liver disease. However, the relationship between FLHS and the insulin resistance mechanisms underlying FLHS is not well elucidated. Therefore, we established an FLHS model induced by feeding a high-energy low-protein diet. In the current study, we found that the fasting glucose and insulin concentrations were elevated in the FLHS group compared with the control group during the experimental period. The results of the oral glucose tolerance test (OGTT) and insulin sensitivity test (IST) showed a high level of insulin resistance in the FLHS model. InsR, 4EBP-1, Glut-1 and Glut-3 mRNA expression were decreased, and TOR, S6K1, and FOXO1 were elevated (P < 0.05). Metabolomic analysis with GC/MS identified 46 differentially expressed metabolites between these two groups, and of these, 14 kinds of metabolism molecules and 32 kinds of small metabolism molecules were decreased (P < 0.05). Further investigation showed that glucose, lipid and amino acid metabolism blocks in the progression of FLHS by GO functional and pathway analysis. Overall, these results suggest that insulin resistance participated in FLHS; comprehensively, metabolites participated in the dysregulated biological process.

Abstract
The aim of this work was a comparative study of the amount of antimicrobial peptides—human neutrophil peptides—defensins (HNP), hepcidin, bactericidal/permeability-increasing protein (BPI), and endotoxin in β-thalassemia. Blood samples of 135 patients with thalassemia were investigated. All patients were divided into 3 groups. The first group included patients with heterozygous form (n = 45). The second group consisted of patients with homozygous form before splenectomy (n = 45). The third group included patients with homozygous form after splenectomy (n = 45). The age of patients varied from 2 to 18 years. Biochemical [unconjugated and conjugated bilirubin, alkaline phosphatase, hemoglobin, ferritin, aspartate transaminase (AST), alanine transaminase (ALT), mean corpuscular volume (MCV)] and immune (IgA, IgM, IgG, phagocytic activity) parameters were defined. Obtained results suggest that increased levels of endogenous antimicrobial peptides are associated with the development of the infectious process and reflect the dynamics of changes in biochemical parameters and immune status.

Abstract
Hepatitis C virus (HCV) infection is associated with extrahepatic manifestations, among these there is an increased risk of atherosclerosis and cardiovascular disease as well as an increased cardiovascular mortality. Several direct and indirect HCV pro-atherogenic mechanisms have been proposed. HCV lives and replicates within carotid plaques, promoting a local environment of pro-atherogenic factors. In addition, it causes conditions such as insulin resistance, diabetes, hepatic steatosis, cryoglobulinemia and endotoxinemia that are associated with the development of atherosclerosis and cardiovascular disease. Therapeutic regimens based on direct-acting antiviral agents (DAA) are currently available with high efficacy in HCV clearance and improvement of liver disease, but does HCV eradication also improve atherosclerosis and the risk of cardiovascular disease? Recently, a multi-center study has shown that elimination of HCV improves carotid atherosclerosis. Two studies have shown that DAA treatments significantly reduce the risk of cardiovascular events. Several studies have assessed the impact of HCV clearance on pro-atherosclerosis metabolic conditions showing improvement in cardiovascular risk biomarkers, disappearance or improvement of insulin resistance, reduction of risk of developing diabetes and improvement of glycemic control. There are also evidences that HCV clearance promotes the recovery of cytokines and inflammatory markers associated with atherosclerosis and the disappearance of cryoglobulinemia. Available data show that clearance of HCV by DAAs is associated with an improvement in atherosclerosis and metabolic and immunological conditions that promote the development of cardiovascular disease. However, the data are not sufficient to allow definitive conclusions and further studies will be needed to definitively clarify the impact of HCV clearance on atherosclerosis and cardiovascular disease.
