interleukin-8 and Hepatitis-B--Chronic

Middle East Respiratory Syndrome (MERS) is a novel respiratory illness firstly reported in Saudi Arabia in 2012. It is caused by a new corona virus, called MERS corona virus (MERS-CoV). Most people who have MERS-CoV infection developed severe acute respiratory illness.. This work is done to determine the clinical characteristics and the outcome of intensive care unit (ICU) admitted patients with confirmed MERS-CoV infection.. This study included 32 laboratory confirmed MERS corona virus infected patients who were admitted into ICU. It included 20 (62.50%) males and 12 (37.50%) females. The mean age was 43.99 ± 13.03 years. Diagnosis was done by real-time reverse transcription polymerase chain reaction (rRT-PCR) test for corona virus on throat swab, sputum, tracheal aspirate, or bronchoalveolar lavage specimens. Clinical characteristics, co-morbidities and outcome were reported for all subjects.. Most MERS corona patients present with fever, cough, dyspnea, sore throat, runny nose and sputum. The presence of abdominal symptoms may indicate bad prognosis. Prolonged duration of symptoms before patients' hospitalization, prolonged duration of mechanical ventilation and hospital stay, bilateral radiological pulmonary infiltrates, and hypoxemic respiratory failure were found to be strong predictors of mortality in such patients. Also, old age, current smoking, smoking severity, presence of associated co-morbidities like obesity, diabetes mellitus, chronic heart diseases, COPD, malignancy, renal failure, renal transplantation and liver cirrhosis are associated with a poor outcome of ICU admitted MERS corona virus infected patients.. Plasma HO-1, ferritin, p21, and NQO1 were all elevated at baseline in CKD participants. Plasma HO-1 and urine NQO1 levels each inversely correlated with eGFR (. SnPP can be safely administered and, after its injection, the resulting changes in plasma HO-1, NQO1, ferritin, and p21 concentrations can provide information as to antioxidant gene responsiveness/reserves in subjects with and without kidney disease.. A Study with RBT-1, in Healthy Volunteers and Subjects with Stage 3-4 Chronic Kidney Disease, NCT0363002 and NCT03893799.. HFNC did not significantly modify work of breathing in healthy subjects. However, a significant reduction in the minute volume was achieved, capillary [Formula: see text] remaining constant, which suggests a reduction in dead-space ventilation with flows > 20 L/min. (ClinicalTrials.gov registration NCT02495675).. 3 组患者手术时间、术中显性失血量及术后 1 周血红蛋白下降量比较差异均无统计学意义（. 对于肥胖和超重的膝关节单间室骨关节炎患者，采用 UKA 术后可获满意短中期疗效，远期疗效尚需进一步随访观察。.. Decreased muscle strength was identified at both time points in patients with hEDS/HSD. The evolution of most muscle strength parameters over time did not significantly differ between groups. Future studies should focus on the effectiveness of different types of muscle training strategies in hEDS/HSD patients.. These findings support previous adverse findings of e-cigarette exposure on neurodevelopment in a mouse model and provide substantial evidence of persistent adverse behavioral and neuroimmunological consequences to adult offspring following maternal e-cigarette exposure during pregnancy. https://doi.org/10.1289/EHP6067.. This RCT directly compares a neoadjuvant chemotherapy regimen with a standard CROSS regimen in terms of overall survival for patients with locally advanced ESCC. The results of this RCT will provide an answer for the controversy regarding the survival benefits between the two treatment strategies.. NCT04138212, date of registration: October 24, 2019.. Results of current investigation indicated that milk type and post fermentation cooling patterns had a pronounced effect on antioxidant characteristics, fatty acid profile, lipid oxidation and textural characteristics of yoghurt. Buffalo milk based yoghurt had more fat, protein, higher antioxidant capacity and vitamin content. Antioxidant and sensory characteristics of T. If milk is exposed to excessive amounts of light, Vitamins B. The two concentration of ZnO nanoparticles in the ambient air produced two different outcomes. The lower concentration resulted in significant increases in Zn content of the liver while the higher concentration significantly increased Zn in the lungs (p < 0.05). Additionally, at the lower concentration, Zn content was found to be lower in brain tissue (p < 0.05). Using TEM/EDX we detected ZnO nanoparticles inside the cells in the lungs, kidney and liver. Inhaling ZnO NP at the higher concentration increased the levels of mRNA of the following genes in the lungs: Mt2 (2.56 fold), Slc30a1 (1.52 fold) and Slc30a5 (2.34 fold). At the lower ZnO nanoparticle concentration, only Slc30a7 mRNA levels in the lungs were up (1.74 fold). Thus the two air concentrations of ZnO nanoparticles produced distinct effects on the expression of the Zn-homeostasis related genes.. Until adverse health effects of ZnO nanoparticles deposited in organs such as lungs are further investigated and/or ruled out, the exposure to ZnO nanoparticles in aerosols should be avoided or minimised.

To probe into the methods and therapeutic effects of electroacupuncture (EA) on hepatitis B.. 60 hospitalized cases of mild or moderate hepatitis B were randomly divided into a treatment group (30 cases) and a control group (30 cases). EA was applied at the points selected according to the differentiation of symptoms and signs. The treatment was given once daily for 30 minutes, and 2 weeks of treatments constituted a therapeutic course, with 2-3 courses on average in the treatment group. Conventional treatment for liver protection was given in the control group.. As compared with the control group, the duration of the treatment for recovery of the hepatic functions was significantly shorter, and the IL-8 level significantly lower in the treatment group.. In treating hepatitis B, EA is effective in improving symptoms, recovering hepatic functions, and regulating immune functions to certain extent.

To explore the effect of He Jie Tang (decoction for medication) on serum levels of T lymphocyte subsets, NK cell activity and cytokines in chronic hepatitis B patients.. Eighty-five patients with chronic hepatitis B were divided randomly into two groups. Fifty patients in group I were treated with He Jie Tang (HJT) and 35 patients in group II were treated with combined medication. The levels of T-lymphocyte subsets (CD(3)(+), CD(4)(+), CD(8)(+)), NK cell activity, cytokines (TNF-alpha, IL-8, sIL-2R) were observed before and after the treatment. Another 20 normal persons served as group 3.. The level of CD(4)(+) cells and NK cell activity were lower, whereas the level of CD(8)(+) cells in patients was higher than that in normal persons (t = 2.685, 3.172, and 2.754 respectively; P<0.01). The levels of TNF-alpha, IL-8, and sIL-2R in chronic hepatitis B patients were higher than those in normal persons (t = 3.526, 3.170, and 2.876 respectively; P<0.01). After 6 months of treatment, ALT, AST, and TB levels in the two groups were obviously decreased (t = 3.421, 3.106, and 2.857 respectively; P<0.01). The level of CD(4)(+) cells and NK cell activity were increased whereas the level of CD(8)(+) cells decreased (t = 2.179, 2.423, and 2.677 respectively; P<0.05) in group I. The levels of TNF-alpha, IL-8, and sIL-2R in group I were decreased significantly after the treatment (t = 2.611, 2.275, and 2.480 respectively; P<0.05) but had no significant difference in group II after the treatment (t = 1.906, 1.833, and 2.029 respectively; P>0.05). The total effective rate had no significant difference between the two groups (c2 = 2.882, P>0.05) but the markedly effective rate was significantly different between the two groups (c2 = 5.340, P<0.05).. HJT is effective in treating chronic hepatitis B. HJT seems to exert its effect by improving the cellular immune function and decreasing inflammatory cytokines in chronic hepatitis B patients. The function of HJT in protecting liver function in the process of eliminating virus needs to be further studied.

Acute-on-chronic liver failure (ACLF) is a distinctive and severe syndrome, marked by an excessive systemic inflammatory response. In vivo, interleukin 8 (IL-8) is an essential pro-inflammatory cytokine. We aimed to investigate the value of serum IL-8 levels in predicting mortality in ACLF patients in the background of hepatitis B virus-related cirrhosis.. In this study, we conducted a retrospective analysis of the clinical baseline characteristics of 276 patients with ACLF in the context of HBV-related cirrhosis. Logistic regression analysis was employed to identify independent risk factors for short-, intermediate-, and long-term mortality. Using these independent risk factors, we developed a nomogram model, which was subsequently validated. To assess the clinical usefulness of the nomogram model, we performed decision curve analysis (DCA).. Out of the 276 patients with ACLF, 98 (35.5%), 113 (40.9%), and 128 (46.4%) died within 28, 90, and 180 days, respectively. Serum IL-8 levels were only an independent predictor of 28-day mortality and could simply classify ACLF patients. Conversely, mean arterial pressure (MAP), HBV-DNA, and COSHACLF IIs were independent predictors of mortality across all three observation periods. We constructed a nomogram based on IL-8 that was able to visualise and predict 28-day mortality with a C-index of 0.901 (95% CI: 0.862-0.940). Our calibration curves, Predicted Probability of Death & Actual Survival Status plot, and Confusion Matrix demonstrated the nomogram model's strong predictive power. DCA indicated the nomogram's promising clinical utility in predicting 28-day mortality in ACLF patients.. Serum IL-8 levels predict short-term mortality in ACLF patients in the background of HBV-associated cirrhosis, and the developed Nomogram model has strong predictive power and good clinical utility.. Systemic inflammatory response is a pathophysiological feature of patients with acute-on-chronic liver failure, and the serum level of interleukin-8 can predict the short-term prognosis of patients.

Knowing about cytokine profile contributes to clarify the underling immune mechanism of HBsAg seroclearance rate increase. This study aims to investigate cytokine changes during nucleos(t)ide analogues (NAs) and peginterferon-α (Peg-IFNα) therapy and their impact on the HBsAg serologic response.. A total of 78 HBV DNA-negative chronic Hepatitis B (CHB) patients were studied after a lead-in phase of NAs with complete serum cytokines. Serum cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-17 and TNF-α) were quantified by flow cytometry (FCM) every 24 weeks, before, during and at the end of NAs and Peg-IFNα treatment. Clinical and laboratory data were also taken at the same time. Analysis was performed between cured and uncured groups characterized by HBsAg seroclearance. PBMCs samples from five patients (two in cured group and three in uncured group) were analyzed by FCM.. HBsAg seroclearance was achieved in 30 (38,5%) patients defined as the cured group. In comparison to uncured individuals, cured patients showed similar expressions of serum IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17 and TNF-α during the treatment of NAs and Peg-IFNα. Compared with the uncured groups, IL-5 was remarkably increased in cured patients. IL-5 at weeks 24 and 48 were associated with HBsAg seroconversion (p=0.033 and 0.027, respectively). PBMCs sample analysis confirmed the predicted value of IL-5 in response to NAs and Peg-IFNα treatment.. IL-5 at weeks 24 and 48 might be used as a biomarker for HBsAg seroclearance in NAs-experienced CHB patients treated with NAs combined with Peg-IFNα. More importantly, exploiting the expression of this cytokine may help to develop a better understanding of the immune pathogenesis of chronic HBV infection.

The events in the immune response to hepatitis B virus (HBV) remain unclear. We analyzed the direct influence of HBV on gene expression in human hepatocytes under immunodeficient conditions using a human hepatocyte chimeric mouse model. HBV-infected or non-infected chimeric mouse livers were collected, and gene expression profiles were compared. Since IL-8 was the most significantly up-regulated gene at 8 weeks after HBV infection, we focused on IL-8 and found that HBx and the large HBs (L-HBs) protein induce transcription of IL-8 via endoplasmic reticulum stress. This stress induces IL-8 transcription via NFAT activation and contributes to suppression of interferon responsiveness in HBV-infected human hepatocytes. In the present study, we identified a novel regulatory mechanism in which the L-HBs protein activates IL-8 via endoplasmic reticulum stress, suggesting a key role for IL-8 in the immune response to HBV and a potential new target for antiviral treatments of HBV infection.

The role of NK cells on inducing liver injury in patients with HBV-related acute-on-chronic liver failure (HBV-ACLF) is not well understood. The aim of this study was to determine the cytotoxicity of tumor necrosis factor-related apoptosis inducing ligand (TRAIL)-expressed NK cells from HBV-ACLF patients and facilitate a better understanding of the immune pathogenesis of HBV-ACLF.. Peripheral blood samples were obtained from HBV-ACLF patients, mild chronic hepatitis B (CHB) patients and healthy controls (HC). Circulating NK cells phenotype was determined using flow cytometry. Serum cytokine concentrations were ascertained using the CBA Inflammation kit. Cell apoptosis was analyzed using the FITC-annexin V Apoptosis Detection Kit.. Peripheral NK cells from HBV-ACLF expressed higher levels of TRAIL than those from CHB and HC. Expression of TRAIL on NK cells was correlated positively with serum IL-6 and IL-8 concentrations in HBV-ACLF patients, which is further confirmed by cytokines stimulation in vitro. NK cells caused a significant increase of apoptotic hepatocytes, and further increased the frequency of apoptosis in IL-6 and IL8-stimulated hepatocytes; the apoptosis was then inhibited partially by an anti-TRAIL monoclonal antibody.. These results suggested that inflammation cytokines elevated in patients with HBV-ACLF may promote NK cell mediated cytotoxicity through TRAIL pathway.

The liver is the largest gland in the human body and functions as an innate immune organ. Liver macrophages called Kupffer cells (KC) constitute the largest group of macrophages in the human body. Innate immune responses involving KC represent the first line of defense against pathogens in the liver. Human monocyte-derived macrophages have been used to characterize inflammasome responses that lead to the release of the proinflammatory cytokines IL-1β and IL-18, but it has not yet been determined whether human KC contain functional inflammasomes. We show, to our knowledge for the first time, that KC express genes and proteins that make up several different inflammasome complexes. Moreover, activation of KC in response to the absent in melanoma 2 (AIM2) inflammasome led to the production of IL-1β and IL-18, which activated IL-8 transcription and hepatic NK cell activity, respectively. Other inflammasome responses were also activated in response to selected bacteria and viruses. However, hepatitis B virus inhibited the AIM2 inflammasome by reducing the mRNA stability of IFN regulatory factor 7, which regulated AIM2 transcription. These data demonstrate the production of IL-1β and IL-18 in KC, suggesting that KC contain functional inflammasomes that could be important players in the innate immune response following certain infections of the liver. We think our findings could potentially aid therapeutic approaches against chronic liver diseases that activate the inflammasome.

The newborn immune system is characterized by an impaired Th1-associated immune response. Hepatitis B virus (HBV) transmitted from infected mothers to newborns is thought to exploit the newborns' immune system immaturity by inducing a state of immune tolerance that facilitates HBV persistence. Contrary to this hypothesis, we demonstrate here that HBV exposure in utero triggers a state of trained immunity, characterized by innate immune cell maturation and Th1 development, which in turn enhances the ability of cord blood immune cells to respond to bacterial infection in vitro. These training effects are associated with an alteration of the cytokine environment characterized by low IL-10 and, in most cases, high IL-12p40 and IFN-α2. Our data uncover a potentially symbiotic relationship between HBV and its natural host, and highlight the plasticity of the fetal immune system following viral exposure in utero.

This study aimed to investigate miR-106a expression in peripheral blood mononuclear cells (PBMCs) of chronic hepatitis B (CHB) patients and to analyze the function of miR-106a.. miR-106a expression levels in PBMCs from 40 healthy controls and 56 CHB patients were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR). The luciferase activity assays were used to determine whether miR-106a binds to 3'UTR of IL-8. miR-106a mimics and inhibitors were transfected into healthy PBMCs. IL-8 mRNA and protein levels were detected and determined by qRT-PCR and ELISA, respectively.. The qRT-PCR results suggested that the PBMC miR-106a levels were decreased in CHB patients. IL-8 was augmented in CHB patients and was inversely correlated with miR-106a levels. The luciferase activity assays indicated that IL-8 is a target of miR-106a. Exogenous expression of miR-106a could significantly repress IL-8 expression at both mRNA and protein levels in PBMCs, whereas miR-106a inhibitor had the opposite effects.. This study suggested that miR-106a is downregulated in PBMCs of CHB patients and that miR-106a may play an important role in CHB by targeting IL-8.

The host immune response is closely related to the prognosis of disease and viral persistence in hepatitis B (HBV) and hepatitis C virus (HCV) infections. Although it is well known that cytokines and genetic factors play important roles in the pathogenesis of chronic HBV and HCV infections, the underlying mechanisms are not fully understood. This study was conducted to determine the role of interleukin (IL)-1β, IL-1 receptor antagonist (IL-1RA) and IL-8 gene polymorphisms in chronic hepatitis B and C infections. A total of 361 subjects, 171 with chronic hepatitis B (62 female, 109 male; age range: 18-74 yrs) and 104 with chronic hepatitis C (63 female, 41 male; age range: 25-79 yrs), and a control group of 86 healthy subjects (41 female, 45 male; age range: 18-72 yrs) were included in the study. Following the DNA extractions from peripheral blood leukocytes of the study groups, single nucleotide polymorphisms of IL-1β -31, -511, +3954; IL-1RA and IL-8 -251, -353, -738, -845 gene regions were investigated by using specific primers with real-time PCR method. It was found that the genotype frequency of IL-8 -251 AT (OR: 7.895, p= 0.003) and IL-8 -738 TA (OR: 6.317, p= 0.007) in patients with chronic hepatitis B and the genotype frequency of IL-1β-31 CT (OR: 6.757, p= 0.001), IL-1β -511 CT (OR: 4.060, p= 0.004), IL-8 -251 AT, (OR: 13.622, p= 0.001), IL-8 -738 TA (OR: 14.058, p= 0.001), and IL-8 -845 TC (OR: 2.539, p= 0.004) in patients with chronic hepatitis C was significantly higher than the control group. When the allelic frequency was compared between chronic hepatitis B patients and the control group, it was determined that IL-1β +3954 T allel increased the disease risk 1.5 times (p< 0.05), however, no statistically significant difference was detected for the other allels. It was also determined that IL-8 -845 C allel increased the disease risk 0.6 times in chronic hepatitis C (p< 0.05) and no statistically significant difference was detected for the other allels (p> 0.05). In conclusion, IL-1β -31, -511 and IL-8 -251, -738, -845 gene polymorphisms may play a role in the chronicity of hepatitis B and C infection. In order to determine the importance of this cytokine polymorphisms in hepatitis B and hepatitis C virus infections, large-scale studies with different patient groups such as carriers, chronic hepatitis, cirrhosis, and hepatocellular carcinoma should be conducted to elucidate the molecular mechanisms underlying the disease process.

The objective of this study was to analyze the expression levels of IL-8 in serum and liver tissues from patients with chronic hepatitis B (CHB) infection and to investigate whether IL-8 may antagonize interferon-alpha (IFN-α) antiviral activity against HBV. IL-8 expression in serum was determined by enzyme linked immunosorbent assay (ELISA), and fluorescence-based quantitative real-time PCR (RT-qPCR) was used to measure IL-8 mRNA in peripheral blood mononuclear cells (PBMCs) in patients with CHB. IL-8 protein expression was detected in liver biopsy tissues by immunohistochemistry. In addition, the differences in serum IL-8 and PBMCs mRNA levels were also observed in patients with different anti-viral responses to IFN-α. Compared to normal controls, serum IL-8 protein and mRNA levels were increased in CHB patients, IL-8 levels were positively correlated with the severity of liver inflammation/fibrosis. Moreover, serum IL-8 protein and mRNA levels were positively correlated with serum alanine aminotransferase (ALT) level and negatively correlated with serum prealbumin (PA) level. IL-8 expression was mainly located in portal area of liver tissues and was increased with the severity of liver inflammation and fibrosis stage. The expression serum and mRNA levels of IL-8 in the CHB patients with a complete response to IFN-α are significantly lower than that of the patients with non-response to IFN-α treatment. It is suggested that IL-8 might play important roles in the pathogenesis of CHB. Moreover, interferon resistance may be related to the up-regulation of IL-8 expression in the patients did not respond to IFN-α treatment.

It is widely accepted that chronic hepatitis B virus (HBV) infection is the result of an ineffective antiviral immune response against HBV infection. Our previous study found that the hepatitis B surface Ag (HBsAg) was related to decreased cytokine production induced by the TLR2 ligand (Pam3csk4) in PBMCs from chronic hepatitis B patients. In this study, we further explored the mechanism involved in the inhibitory effect of HBsAg on the TLR2 signaling pathway. The results showed that both Pam3csk4-triggered IL-12p40 mRNA expression and IL-12 production in PMA-differentiated THP-1 macrophage were inhibited by HBsAg in a dose-dependent manner, but the production of IL-1β, IL-6, IL-8, IL-10, and TNF-α was not influenced. The Pam3csk4-induced activation of NF-κB and MAPK signaling were further examined. The phosphorylation of JNK-1/2 and c-Jun was impaired in the presence of HBsAg, whereas the degradation of IκB-α, the nuclear translocation of p65, and the phosphorylation of p38 and ERK-1/2 were not affected. Moreover, the inhibition of JNK phosphorylation and IL-12 production in response to Pam3csk was observed in HBsAg-treated monocytes/macrophages (M/MΦs) from the healthy donors and the PBMCs and CD14-positive M/MΦs from chronic hepatitis B patients. Taken together, these results demonstrate that HBsAg selectively inhibits Pam3csk4- stimulated IL-12 production in M/MΦs by blocking the JNK-MAPK pathway and provide a mechanism by which HBV evades immunity and maintains its persistence.

High levels of serum interleukin-8 (IL-8) have been detected in chronic hepatitis B (CHB) patients during episodes of hepatitis flares. We investigated whether hepatitis B virus (HBV) may directly induce IL-8 production and whether IL-8 may antagonize interferon-alpha (IFN-α) antiviral activity against HBV. We showed that CHB patients had significantly higher IL-8 levels both in serum and in liver tissue than controls. In HBV-replicating HepG2 cells, IL-8 transcription was significantly activated. AP-1, C/EBP and NF-kB transcription factors were concurrently necessary for maximum IL-8 induction. Moreover, HBx viral protein was recruited onto the IL-8 promoter and this was paralleled by IL8-bound histone hyperacetylation and by active recruitment of transcriptional coactivators. Inhibition of IL-8 increases the antiviral activity of IFN-α against HBV. Our results indicate that HBV activates IL-8 gene expression by targeting the epigenetic regulation of the IL-8 promoter and that IL-8 may contribute to reduce HBV sensitivity to IFN-α.

To study the mRNA levels of chemokine receptor CXCR1, CXCR2 and IL-8 in the patients with chronic hepatitis B and their association with IFN therapy.. The mRNA levels of CXCR1, CXCR2 and IL-8 in peripheral blood mononuclear cells(PBMC)of chronic hepatitis B patients were determined by real-time RT-PCR before and during the IFN-α therapy.. The mRNA levels of CXCR1(0.4474 ± 0.0386)and IL-8(1.1897 ± 0.1028)in peripheral blood of the patients with chronic hepatitis B were significantly higher than those in healthy donors(P<0.01). The mRNA level of CXCR2(0.4720 ± 0.0458)was higher than those in healthy donors, but there was no significant differences between the two groups. During the treatment, the mRNA levels of CXCR1, CXCR2 and IL-8 obviously decreased. After treatment for six month, the mRNA level of CXCR1(0.4129 ± 0.0395), CXCR2(0.4461 ± 0.0477) and IL-8(0.8660 ± 0.1307)were significantly lower than those before treatment(P<0.01 or P<0.05). Additionally, the expressive levels of CXCR1, CXCR2 and IL-8 in the high HBV loading group(HBV-DNA>10(6);)were much higher than those in the low HBV loading group(HBV-DNA<10(6);).. CXCR1 and IL-8 may contribute to hepatic inflammation. Among them, CXCR1, CXCR2 and IL-8 decrease after IFN treatment, which illustrates that IFN-α plays an important role in down-regulating inflammation response, controlling the development of the patients' condition.

Lipopolysaccharide (LPS) is suspected to trigger primary biliary cirrhosis (PBC) in susceptible individuals, yet the precise mechanism of its effect in PBC remains largely unknown. The aim of this study was to investigate altered responses to LPS ligand for Toll-like receptors (TLRs) in pathogenesis of PBC in vivo and in vitro.. In vivo, we investigated levels of LPS and pro-inflammatory cytokines in sera and expression of LPS receptors in liver tissues from 162 patients with PBC, 325 patients with other liver diseases and 80 healthy controls. In vitro, altered responses to LPS on monocytes and cultured human biliary epithelial cells (BECs) from patients with PBC were determined.. Significantly higher levels of LPS in patients with PBC were detected, compared with patients with other liver diseases and healthy controls. Immunohistochemically, expression of TLR4, CD14, CD68 and NF-κB was significantly enhanced in liver tissues from patients with PBC. Before LPS stimulation, we found significantly higher serum levels of tumor necrosis factor-α, interleukin (IL)-1β, IL-6 and IL-8 in patients with PBC than those in healthy controls. After LPS stimulation, TLR4 expression and pro-inflammatory cytokine production in CD14-positive monocytes and cultured BEC from patients with PBC increased significantly.. These results indicated that patients with PBC were prone to exhibit higher serum LPS level, hypersensitivity of monocytes and BEC to LPS, and enhanced production of pro-inflammatory cytokines. LPS altered expression of TLR4, CD14 and NF-κB on monocytes and BEC, which may be implicated in the pathogenesis and progression of PBC.

To research serum level of interleukin-17 (IL-17) associated with the progression of hepatic injury in the chronic patients with hepatitis B.. The serum level of IL-17 was measured by ELISA and the serum levels of IL-6, IL-8 were measured by RIA in patient groups and healthy group, the patient groups including 42 mild patients, 37 moderate patients and 38 severe patients.. IL-17,IL-6 and IL-8 levels in patient patients were significantly higher than those in healthy people (P < 0.01). There is no significant difference among mild patients and moderate patients. Compared with mild patients and moderate patients,the cytokines lever were significantly higher in severe patients (P < 0.01).. IL-17 as a new cytokine probably play a multiple role as immune factor and inflammation element in the progression of the chronic hepatitis B disease. Maybe, it can provide a new approach to the therapy of the chronic hepatitis B.

Hepatitis B virus (HBV) causes chronic infection in more than 350 million people worldwide. It replicates in hepatocytes but is non-cytopathic; liver damage is thought to be immune mediated. Here, we investigated the role of innate immune responses in mediating liver damage in patients with chronic HBV infection. Longitudinal analysis revealed a temporal correlation between flares of liver inflammation and fluctuations in interleukin (IL)-8, interferon (IFN)-alpha, and natural killer (NK) cell expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) directly ex vivo. A cross-sectional study confirmed these findings in patients with HBV-related liver inflammation compared with healthy carriers. Activated, TRAIL-expressing NK cells were further enriched in the liver of patients with chronic HBV infection, while their hepatocytes expressed increased levels of a TRAIL death-inducing receptor. IFN-alpha concentrations found in patients were capable of activating NK cells to induce TRAIL-mediated hepatocyte apoptosis in vitro. The pathogenic potential of this pathway could be further enhanced by the ability of the IFN-alpha/IL-8 combination to dysregulate the balance of death-inducing and regulatory TRAIL receptors expressed on hepatocytes. We conclude that NK cells may contribute to liver inflammation by TRAIL-mediated death of hepatocytes and demonstrate that this non-antigen-specific mechanism can be switched on by cytokines produced during active HBV infection.

To evaluate the clinical efficacy and study the mechanism of combining plasma exchange and continuous veno-venous hemofiltration in treating patients with chronic severe viral hepatitis B in their mid- and late stages.. 94 patients suffering from chronic severe viral hepatitis B were divided into three groups. 29 patients were treated with plasma exchange plus continuous veno-venous hemofiltration (group A). 31 patients were treated with plasma exchange alone (group B). 34 patients received routine treatment (group C). The efficacy of treatment and survival rate of the three groups was investigated. Before and after artificial liver support system treatment the levels of cytokine were examined.. In group A, hyponatremia improved, the levels of interleukin 8 (IL-8) obviously decreased, the level of IL-10 increased, 5 of the 10 patients in coma regained normal consciousness (50.0%) and their survival rate was 48.3%. In group B, hyponatremia did not change, the level of IL-8 and IL-10 did not change. 2 of 11 patients in coma regained normal consciousness (18.2%) while survival rate was 22.6%. In group C, 1 of 11 patients in coma regained normal consciousness (9.1%) while survival rate was 20.6%.. It shows that plasma exchange with continuous veno-venous hemofiltration in treating patients with mid- and late stage chronic severe viral hepatitis B can increase the survival rate. IL-8 can be significantly removed, IL-10 significantly increased. This combined therapy is easy to practice, and should be used as an artificial liver support system.

To investigate the cellular immunological changes in children with viral hepatitis, interleukin 6 (IL-6), interleukin 8 (IL-8), interferon alpha (IFN alpha), and tumor necrosis factor alpha (TNF alpha) in supernatant of cultured peripheral blood mononuclear cells (PBMCs) of 49 children with hepatitis A, B or C were measured. The levels of IL-6, IL-8, TNF alpha in PBMCs of the 3 viral hepatitis groups were increased and the level of IFN alpha decreased as compared with those of normal control group. But there were no significant differences among the 3 viral hepatitis groups. It was concluded that cellular immunological disorders were related to the onset and the induced damage of the viral hepatitis in children.
