However, we cannot exclude an unintended selection bias in our present study because it appears likely that patients who suffered from an aggressive course of HCV infection were more readily considered for antiviral treatment during their scheduled follow-up visits, compared with patients with a mild disease course. Second, our study lacks the comparison of paired biopsy samples obtained at 20, 25, and 35 years after infection to evaluate the histological rate of fibrosis progression. However, our present findings are in agreement with a recent report showing slow histological

fibrosis progression rates in Fulvestrant supplier paired biopsy samples obtained from treatment-naïve patients of the Irish anti-D cohort over a period of 5 years.[24] Our findings are also consistent with another extensive histological follow-up study by Poynard et al.,[21] who reported similar slow fibrosis progression patterns in young women with chronic hepatitis C (CHC). In the Irish anti-D cohort, a 22-year follow-up study also showed mild fibrosis progression in affected women.[9] Third, we could not reliably evaluate alcohol consumption in our patients over this long observation period. However, we observed only a minority of patients with excessive alcohol consumption in our 25-year follow-up study.[12] In summary, we provide evidence for a mild, but

significant, Alvelestat in vivo disease progression at 35 years after infection in the German HCV (1b)-contaminated anti-D cohort, which largely depended on the HCV infection status of the participating patients. Patients with self-limited HCV infection or SVRs to antiviral treatment were protected from progressive liver fibrosis and showed the best clinical long-term outcome. The results of the present study will help attending physicians to counsel patients on the long-term outcome Bcl-w of CHC.

“Non-alcoholic fatty liver disease (NAFLD) overlapping with chronic hepatitis B virus (HBV) infection is undergoing a rapid increase in China. Therefore,

the establishment and character of an animal model with both NAFLD and chronic HBV infection has become an urgent task. Mice with chronic HBV genotype B infection were established with a microinjection of oocytes. Transgenic and nontransgenic mice were then randomized into groups of NAFLD + HBV, HBV, NAFLD, and control and were treated with high-fat diets or common forage. At 8, 16, and 24 weeks, characteristics of NAFLD were evaluated by physical indices, liver function tests, glycolipid metabolism, and histopathological scoring. Viral dynamics were also analyzed by HBV-DNA and HBV-related antigens. Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) were expressed, and HBV-DNA was replicated in HBV transgenic mice at different stages in the serum and liver.

Ezetimibe was resolved

in dimethylsulfoxide (DMSO), and DMSO was used as control. MCA-RH7777 cells from the American Type Culture Collection were cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine (Equitech-Bio, Kerrville, TX, USA) and 10% horse serum (Invitrogen). The cells were cultured at 37°C under 5% CO2 humidified air. After overnight incubation, the cells were washed with phosphate-buffered saline and first pretreated with or without ezetimibe (50 μM) for 16 h and then exposed to carbon tetrachloride (CCL4; 1 mM) (Wako, Osaka, Japan) in the presence or absence of ezetimibe (50 μM) for 8 h. Mitosox Red Mitochondrial superoxide indicator (Invitrogen, San Diego, CA, USA) Rucaparib manufacturer was used for detecting localized Fulvestrant nmr intracellular sources of ROS following the manufacturer’s instructions. Fluorescent images from multiple fields of view were captured using a fluorescence microscope (KEYENCE BZ-8000 microscope). Intracellular ROS level was determined using 2′,7′-dichlorofluorescein diacetate (DCFDA) Cellular Reactive Oxygen Species Detection Assay Kit (Abcam) following the manufacturer’s

instructions. All results are expressed as mean ± standard deviation. Statistical comparisons were made using the two-independent samples Student’s t-test, Mann–Whitney U-test, and one-way anova. Differences with P < 0.05 were regarded as significant. All statistical analyses were performed using SPSS for Windows ver. 17. WE MONITORED FOOD 17-DMAG (Alvespimycin) HCl consumption and bodyweight of all groups throughout the observation period. Baseline bodyweight,

final bodyweight, liver weight, and liver weight to bodyweight ratio were similar in the CT and the EZ (Table 1). Liver TG content in EZ was lower than that in CT (P < 0.05) (Table 1). Liver ROS level in EZ was also lower than that in CT (P < 0.05) (Table 1). Food consumption and bodyweight variation were similar in CT and EZ (Supporting information Fig. S1). Ezetimibe group showed smaller lipid deposits and minimal inflammatory cell infiltrates, evaluated by HE-staining and Oil red O staining, compared with CT (Fig. 1a,b). Regarding NASH activity score, EZ had a lower score than CT (1.0 ± 0.8 in EZ vs 2.7 ± 0.8 in CT, P < 0.01) (Table 1). Regarding fibrosis, EZ showed a lower degree of liver fibrosis than CT (Fig. 1b). The fibrosis score was significantly different between the two groups (0.9 ± 0.3 in EZ vs. 1.6 ± 0.3 in CT, P < 0.01) (Table 1). Fasting glucose levels in EZ were lower at 30, 60 and 90 min during ipGTT than those in CT; however, these differences did not reach statistical significance (Supporting information Fig. S2). Serum total cholesterol and TG levels in EZ were lower than those in CT; however, these differences did not reach statistical significance.

The week 1, 2, 4, and 12 samples were drawn before the weekly PegIFN injection. Two patients consented to

an additional blood draw 6 hours after the week 12 PegIFN injection. All subjects gave written informed consent under protocols approved by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) LBH589 in vitro Institutional Review Board, conforming to the ethical guidelines of the 1975 Declaration of Helsinki. Expression of STAT1, phosphorylated STAT1 (pSTAT1), and pSTAT4 were assessed either directly in vivo or after in vitro stimulation of prewarmed heparinized blood without or with 600 ng/mL

of consensus sequence IFN-α (InterMune Inc., Brisbane, CA) for 5 minutes at 37°C. Cells were fixed and erythrocytes were lysed by incubation with a 20-fold excess volume of Lyse/Fix buffer (BD Biosciences, San Jose, CA) for 10 minutes at 37°C. After centrifugation, cells were permeabilized with Perm Buffer (BD Biosciences) for 20 minutes on ice, washed twice, and resuspended in Staining Buffer (BD Biosciences). All samples were stained with anti-CD56-PE (phycoerythrin) (Beckman Coulter, Brea, CA) and anti-CD20-PerCP/Cy5.5 to identify NK cells and B cells, respectively, and with anti-CD3/fluorescein isothiocyanate or anti-CD3-APC to exclude T cells. Cells were additionally stained with anti-STAT1-Alexa647, anti-pSTAT1-Alexa488 Sotrastaurin order (which assesses tyrosine phosphorylation at Y701), or anti-pSTAT4-Alexa488 (assesses

tyrosine phosphorylation at Y693) for 20 minutes at room temperature and analyzed on an LSRII with FacsDiva next version 6.1.3 (BD Biosciences) and FlowJo version 8.8.2 (Tree Star, Ashland, OR) software. Thawed peripheral blood mononuclear cells (PBMCs) were cultured overnight at 37°C in 5% CO2 in Roswell Park Memorial Institute 1640 medium with 10% fetal calf serum (Serum Source International, Charlotte, NC), 1% penicillin/streptomycin, 2 mM of L-glutamine, and 10 mM of 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (Cellgro, Manassas, VA). The next day, PBMCs were counted and stimulated in the presence or absence of K562 cells (ATCC, Manassas, VA) to assess degranulation, as previously described,6 but in the absence of additional cytokines. Thawed PBMCs were stained with ethidium monoazide, anti-CD19-PeCy5 (BD Biosciences), anti-CD14-PeCy5 (Serotec, Raleigh, NC), anti-CD56-PeCy7, anti-CD3-AlexaFluor700 (BD Biosciences), and anti-TRAIL-PE (BD Biosciences). Thawed PBMCs were incubated with or without interleukin (IL)-12 (0.

Patients who had used prophylactic antibiotics

had better 3- and 5-year jaundice-free survival with native liver than patients who had not (OR 3.03, P = 0.009 and OR 2.79, P = 0.01, respectively). Moreover, patients who were jaundice-free at 3 months postsurgery had better 3- and 5-year jaundice-free survival with native liver than those who were not jaundice-free (OR 39.34, 95% CI 17.00-97.06, P < 0.001 and OR 21.43, 95% CI 7.90-58.16, P < 0.001, respectively). Sex did not affect outcome. Intervention by the stool card screening program, Kasai operation before 60 days of age, the use of prophylactic antibiotics, and jaundice-free at 3 months postsurgery were the predictors of quality outcome for BA patients. Cohort B+C had better 3- and 5-year overall survival rates than cohort A (OR 4.64, P < 0.001 and OR 6.63, P = 0.003, respectively) (Figs. 1 and 2; Table 4). Patients who had used selleck chemical prophylactic antibiotics had better 3- and 5-year overall survival rates than those who did not (OR 5.33, P < 0.001 and OR 6.31, P < 0.001, respectively). Those who were jaundice-free at 3 months after Kasai operation had better 3- and 5-year overall survival rates than those who were not jaundice-free (OR 11.15, P < 0.001 and OR 10.85, P < 0.001, respectively). Biliary atresia (BA) is an obliterative cholangiopathy of unknown etiology. It is the most common cause of end-stage liver disease in children, with an incidence of 0.51 per

10,000 in France,10 0.60 per 10.000 in the United Progesterone Kingdom,11 0.70 per 10,000 in Sweden,12 and 0.85 per 10,000 in North America.12 There is a higher incidence in Asia, including 1.04 per 10,000 in Japan13, 14 and 1.78 per 10,000 in Taiwan.7 Taiwan is one of the areas with the highest incidence in the world. Kasai operation is the primary surgical therapy for BA, even in the era of liver transplantation.15 Survival of BA patients with their native liver relies mainly on the success of the Kasai operation,16 which is correlated with age at surgery.13 In the Swiss national study,12 4-year survival

with native liver is 75% in patients who receive the Kasai operation before 46 days, 33% in patients receiving the operation between 46 and 75 days, and 11% in patients receiving the operation after 75 days (P = 0.02). In long-term follow-up, the 20-year survival with native liver is significantly better in patients who receive the operation before the age of 90 days than in those who receive it after 90 days (28% versus 13%; P = 0.006).5 In the current study, patients who underwent Kasai operation before the age of 60 days had significantly better survival with native liver than those receiving the operation after 60 days of age. The earlier age at Kasai operation is indeed an important predictive factor of better long-term survival with native liver. For early diagnosis of BA, the stool card screening program was started in Taiwan in regional areas in 2002 and extended nationwide in 2004.

Even diabetic patients show higher rates of CVD if they have NASH

Even diabetic patients show higher rates of CVD if they have NASH. eNOS derangements have been demonstrated in animal experimental models of NAFLD/NASH. Although clinical and “sublinical” markers (i.e. “intima-media thickness” and “shear stress” evaluation) seem to have confirmed this suspicion, nevertheless, to our knowledge, no experimental studies on humans have directly demonstrated that endothelial dysfunction is associated selleck chemical with NAFLD/NASH and its extent.Aim: to directly demonstrate that eNOS derangement is associated with NAFLD/NASH. Patients and methods: 18 patients (13 males,

5 females) coming to our department of Internal Medicine for NAFLD/NASH diagnosis and/or evaluation were consecutively enrolled from January to April 2014. Every patient underwent clinical evaluation and liver biopsy after informed consent. Patients were divided in two groups according to the presence of NAFLD or NASH. Of every patient we measured eNOS function by evaluating the vasorelaxation activity induced on isolated mice vessels by platelet-rich plasma obtained by peripheral blood samples, and by performing immunoblot assays for platelet

derived eNOS (p-eNOS). Collected data were compared to those coming from an age and sex matched group of healthy volunteers from a local blood bank. All subjects were non-smokers and had no active cardiovascular diseases. Results: Of the 18 pts 7 (38,8%) had NAFLD and 11 (61,7%) had NASH at the liver biopsy. No statistically Inhibitor Library significant differences were found between the two groups and controls for age, sex, BMI, ALT, prevalence

of hypertension, diabetes, dyslipidaemia, obesity and metabolic syndrome. Ureohydrolase Vascular reactivity curves demonstrated a reduced activity of eNOS in patients with NAFLD and NASH in respect to controls (p<0.005). Moreover, densitomet-ric analysis of immunoblot assays for p-eNOS demonstrated a significantly lower expression in NAFLD and NASH patients in respect to controls (p<0.007). Conclusions: Our findings directly demonstrated that eNOS function is reduced in NAFLD and NASH patients. Endothelial dysfunction may be considered as one of the main pathophysiological mechanisms of liver damage in NAFLD/NASH. Disclosures: The following people have nothing to disclose: Mario Masarone, Albino Car-rizzo, Alessandro Federico, Valerio Rosato, Carmine Vecchione, Marcello Persico Background: The role of B cell leukemia-3 (bcl-3) protein – a nuclear member of the IkB family and regulator of the NFkap-paB subunits p50 and p52 – in non-alcoholic fatty liver disease (NAFLD) and the associated metabolic phenotype is unknown. Methods: Therefore, we examined hepatic gluconeogenesis and lipogenesis in a murine NAFLD model using a high-fat, high-carbohydrate diet (HFD) and studied the underlying molecular mechanisms during the development of NAFLD.

Marta García-Valdecasas, Antonio Gil-Gómez, Angela Rojas, Jordi Muntané, Farncisco Javier PAdillo Ruiz, Jose Antonio Del Campo Background: Metabolic syndrome (MS) is a major risk factor for hepatocellular carcinoma (HCC), but the specific molecular pathways of tumorigenesis are incompletely understood in this context. Plasmatic Fatty Acid-Binding Protein 4 (FABP4) levels, a mediator of lipid trafficking in adipocytes, are increased in patients with MS and correlated PARP inhibitor with lesions of non alcoholic steatohepatitis, suggesting a potential role for FABP4 in liver pathogenesis related to MS. In addition, some experimental studies have shown that FABP4 may have an oncogenic potential. The aim of our study was to investigate FABP4 expression and its role in liver carcinogenesis related to MS. Material & Methods FABP4 expression was investigated by Western Blot, immunohistochemistry and RT-PCR on human Lenvatinib HCC and non-tu-moral liver samples related to MS, and compared with samples from patients having

Hepatitis C Virus (HCV) chronic liver disease. Role and regulation of FABP4 were in vitro assessed on cell cultures using HepG2 and HUVEC cells. Results: By contrast to mRNA level, FABP4 protein expression was significantly upregulated in human HCCs related to MS compared to HCCs associated

with HCV infection (4-fold, p=0.01). FABP4 expression was inversely correlated with the number of tumoral nodules and vascular invasion in HCCs related to MS. In patients with MS, FABP4 expression was increased in HCC samples compared with non-tumoral samples (p<0.01). Using double immunostaining, FABP4 expression was restricted to endo-thelial cells in HCC samples. Consequently, we investigated FABP4 regulation in endothelial cells using HUVEC. In HUVEC cells, FABP4 expression was significantly increased by VEGF (25 and 50 ng/ml for 24h, 6- and 14-fold increase, respectively, p<0.01) and Glucose (25 mM for 4 and Selleckchem Erastin 24h, 3-fold increase, p<0.01). Protumoral effects of FABP4 were evaluated in HepG2 cells. In presence of recombinant FABP4 (100 and 200 ng/ml), decreased caspase 3 expression, increased cell proliferation and migration were observed in HepG2 cells (p<0.01). Conclusion: Our results highlight the contribution of endothelial cells in the aggressiveness of HCC via FABP4 upregulation and suggest the potential of FABP4 targeting in patients with MS.

05). Patients with positive upper esophageal pH test (n = 67) also had significantly higher prevalence of acid regurgitation symptoms (43/67 vs 74/152, P < 0.05). Prevalence of other upper gastrointestinal and respiratory symptoms were similar between patients with positive and negative upper and lower pH test. Patients with abnormal EM were significantly older (49 ± 14 vs 45 ± 13 years, P < 0.05) and had higher prevalence of chronic cough than patients with normal EM(30/93 vs 26/143,

P < 0.05). In patients with positive pH tests, the prevalence of dysphagia, chronic cough, and hoarseness of voice were significantly higher in patients with abnormal than those selleck products with normal EM (18/31 vs 18/56, P < 0.05; 12/31 vs 6/56, P < 0.005 and 19/31 vs 18/56, P < 0.01,

respectively). Whereas in patients with negative lower pH tests, only the prevalence of heartburn was significantly lower in patients with normal than those with abnormal EM (26/87 vs 30/62, P < 0.05). Acid regurgitation but not heartburn was associated with GER. Esophageal dysmotility had no significant effect on acid regurgitation symptom but associated with chronic cough, hoarseness of voice, and dysphagia only in patients with abnormal esophageal acid exposure.

“Hepatic ischemia and reperfusion (IR) injury is a major clinical problem that leads to frequent extrahepatic complications including intestinal dysfunction Luminespib solubility dmso and acute kidney injury (AKI). In this study we aimed to determine the mechanisms of hepatic IR-induced extrahepatic organ dysfunction. Mice subjected to 60 minutes of hepatic IR not only developed severe hepatic injury but also developed significant AKI and small intestinal injury. Hepatic IR induced small intestinal Paneth cell degranulation and increased interleukin-17A (IL-17A) levels in portal vein plasma and small intestine. We also detected increased levels of IL-17A messenger RNA (mRNA) and protein in Paneth cells after hepatic IR with laser capture dissection. IL-17A-neutralizing DOCK10 antibody treatment or genetic deletion of either IL-17A or IL-17A receptors significantly protected

against hepatic IR-induced acute liver, kidney, and intestinal injury. Leukocyte IL-17A does not contribute to organ injury, as infusion of wildtype splenocytes failed to exacerbate liver and kidney injury in IL-17A-deficient mice after hepatic IR. Depletion of Paneth cell numbers by pharmacological (with dithizone) or genetic intervention (SOX9 flox/flox Villin cre+/− mice) significantly attenuated intestinal, hepatic, and renal injury following liver IR. Finally, depletion of Paneth cell numbers significantly decreased small intestinal IL-17A release and plasma IL-17A levels after liver IR. Conclusion: Taken together, the results show that Paneth cell-derived IL-17A plays a critical role in hepatic IR injury and extrahepatic organ dysfunction.

37%, but the cumulative incidence was comparable to that of Weste

37%, but the cumulative incidence was comparable to that of Western countries. It is likely that with the rising incidence and increasing proportion of patients with longer follow-up in Asian countries the prevalence of CRC will increase. Disease location.  In the West, CD has been found to occur in the ileum, colon, and both ileum and colon in equal proportions of patients;85 however, a number of studies from the West have reported isolated colonic disease as the most common type of CD.158–161 Ileo-colonic disease appears to be the most common CD location in Asia13,30,52,70,72,73,75–77,139,162–164 (Table 4). A study comparing patients from China and America reported that the Chinese patients had significantly higher rates of ileo-cecal disease

than the Americans.71 In contrast a predominance of colonic disease was seen in two studies in Sri Lanka,35,79 and ileal disease in India78 and Japan.52 Upper gastrointestinal (UGIT) disease has not been routinely reported. However, a study from Hong Kong found that 22.7% of patients had UGIT disease at diagnosis,26 a higher figure than in the West.88,165–167 UGIT disease independently predicted the need for hospitalization. A similar rate of UGIT disease has been reported in previous Indian78 and Chinese72 studies. Disease behavior and course.  Studies from the West have shown rates at diagnosis of inflammatory, stricturing, penetrating and perianal CD as 62–81%, 5–27%, 8–14%, 11–27%,160,161,167,168 respectively. Comparing these data with Asian studies is difficult Benzatropine as they have usually selleck chemical not used a standardized classification system or reported CD behavior at diagnosis. Studies from China, Hong Kong, Korea, Singapore and India, which are mostly hospital based, have reported inflammatory disease in 40–69%,

stricturing disease in 20–28%, and penetrating disease in 10–31% of patients with CD.33,35,70,72,73,75,77,79,164,169 Two studies documenting behavior at diagnosis have reported a high proportion of perianal disease at diagnosis in Hong Kong (33.3%)75 and Korea (36.7%).77 These figures are higher than that reported in large Caucasian CD studies.109,169 The evolution from inflammatory behavior to a more complicated disease behavior (stricturing or penetrating) is well demonstrated in the Western literature,165,170 and has also now been shown in an Asian study from Hong Kong.75 A study from China171 has identified similar risk factors for developing disabling disease as in the West, namely age < 40 years at diagnosis, steroid requirement for treating acute exacerbation and perianal disease at diagnosis.109,161 Other disease features that are similar between the West and Asia include less severe disease in Crohn’s colitis compared to those with ileal involvement,76 and a more severe disease course in younger patients.33 Surgery.

A larger follow-up of the cohort will definitely rule out or conf

A larger follow-up of the cohort will definitely rule out or confirm if LS also predicts overall mortality. Other prognostic factors found in this study were hepatitis B coinfection, high HCV RNA viral load, Selleck Pexidartinib and CTP score. Also, MELD score predicted the development of liver events

but its independent predictive value could not be assessed as a statistical interaction with CTP stage was found. Interestingly, MELD score was associated with overall mortality but not with liver-related mortality after multivariate analyses in our study. In fact, the predictive value of MELD score in HIV/HCV-coinfected patients remains controversial, with previous studies reporting no independent association with survival6, 33 and others finding such an association.34, 35 In our opinion, the lack of an independent association of MELD with liver-related mortality in our cohort could reflect a weaker Selleck Fostamatinib predictive value in the long term, as is the case in this study, than in the short- and mid-term. Achievement of SVR after treatment of hepatitis C is associated with a reduction in liver-related mortality in HIV-negative36 and HIV-positive patients.37 The impact of anti-HCV therapy on the survival or the risk of decompensations

in HIV/HCV-coinfected patients with compensated cirrhosis has been only assessed in two previous cohort studies with apparent conflicting data.33, 38 In the present study, neither exposure to HCV therapy nor achieving SVR during follow-up were associated with a lower risk of developing decompensations. On the contrary, achieving

SVR during follow-up tended to be associated with an improved survival in univariate analyses and exposure to therapy during follow-up was associated with a lower risk of death of any cause. However, these associations did not reach statistical significance, probably due to lack of power and insufficient follow-up. Finally, previous exposure to HCV therapy before enrolment was associated with increased mortality. In our opinion, this association probably reflects a longer time of evolution and an advanced stage of liver disease ADAMTS5 in previous nonresponder patients rather than a worrisome effect of therapy. Additionally, we cannot definitely exclude that selection bias of patients who received prior HCV therapy may have affected our results. Our study may have some limitations. The follow-up period was somewhat short, and the number of some events, particularly liver-related deaths, was relatively low. This might have precluded identifying some potential predictors of mortality as the consecution of SVR. However, the follow-up was long enough to identify other stronger predictors of clinical outcomes such as CTP score or HBV coinfection.

7 Further challenging the activation-induced apoptosis hypothesis

7 Further challenging the activation-induced apoptosis hypothesis are data from Sugalski et al. and Mizuochi et al., which demonstrate that HCV-infected patient B cells manifest increased survival in vitro, relative to HD B-cells.8, 9 Our in vitro data do suggest that soluble factors in plasma from cirrhotic patients promote B-cell survival. A third explanation for peripheral memory B-cell loss could be compartmentalization of activated CD27+ memory B cells to the intrahepatic or lymphoid compartments resulting from up-regulation of homing markers, such as CXCR3,8, 10, 42 a possible mechanism that was

not explored in this study. In the intrahepatic compartment, a profibrotic role of B-cells has been suggested by work in the B-cell-deficient mice treated with carbon tetrachloride,43 by association of plasma cells and activated

stellate cells in autoimmune liver disease,44 and by anecdotal regression of cirrhosis selleck compound library associated with rituximab in case reports.45 The intrahepatic compartment in cirrhotics does appear to be enriched for CD27+ memory B-cells (Supporting Fig. 3), but study of animal models will be critical to precisely define the fate of CD27+ memory B cells in cirrhosis and will be helpful in determining whether or not intrahepatic B-cells may play a pathological role in chronic liver injury/fibrosis. Independent of chronic HCV infection, memory Trichostatin A datasheet CD27+ and, more specifically, CD27+IgM+ B-cells are profoundly reduced in the peripheral blood of patients with cirrhosis with or without HCC in direct relationship with parameters associated with hepatic tuclazepam metabolic dysfunction and portal

hypertension. The remaining B-cells are hyporesponsive to activation via CD40 and TLR9, with impaired up-regulation of costimulation markers, production of TNF-β, and production of IgG. The remaining B cells, upon activation, are also less effective at stimulating CD4+ T-cell responses. The presence of elevated levels of sCD14 and attenuation of B-cell activation by TLR4 and TLR9 blockade in vitro suggest that the loss of peripheral memory B-cells may be a consequence of chronic B-cell activation as a result of increased gut permeability caused by portal hypertension. These findings shed light on vaccine hyporesponsiveness and increased susceptibility to bacterial infection in cirrhotic patients, which might be ameliorated by therapies designed to reduce microbial translocation or block chronic pathogen-induced B-cell activation.
