1% were diagnosed with NASH-induced selleck chemicals llc cirrhosis (Fig. 5). According to that survey, the proportion of NASH cirrhosis is 1.4% in males and 3.4% in females, and there is a significant gender difference (P < 0.005). In that study, obese subjects were few and, at that time, the concept of NASH was not yet commonly accepted by many Japanese doctors. Furthermore, many cases of advanced stage NASH show no fatty deposit, so-called

“burn-out NASH”, resulting in the diagnosis of cryptogenic liver cirrhosis. Therefore, the actual incidence of NASH-related cirrhosis might be higher than was reported. Patients with metabolic syndrome are increasing in number in Japan (Figs. 4,6). Visceral fat accumulation and insulin resistance PD-0332991 manufacturer are usual in these patients. The enhanced insulin resistance caused by the excessive accumulation of body fat (especially visceral fat) is considered to be important in the pathogenesis of fatty liver. The diagnostic criteria for metabolic syndrome established by the Japanese Society of Internal Medicine are as follows:6 an umbilical abdominal circumference (men: 85 cm or more; women: 90 cm or more) which reflects

visceral fat accumulation (a visceral fat area of 100 cm2 or more), and any two of the following four criteria: (i) elevated serum triglyceride level; (ii) reduced HDL cholesterol; (iii) elevated blood pressure; and (iv) elevated fasting plasma glucose. According to the National Health and Nutrition Examination Survey conducted in Japan in 2008, the prevalence of patients afflicted by metabolic syndrome was

25.3% among men and 10.6% among women, whereas patients with pre-metabolic syndrome (patients with an abdominal circumference of ≥85 cm in men and 90 cm in women, and who fulfill one other criterion) accounted for 21.9% of the men and 8.3% of the women. Therefore, approximately half of Japanese men and about 20% of Japanese women might have metabolic syndrome or be predisposed to metabolic syndrome.7 The criteria for metabolic syndrome are useful for the screening of NAFLD. The previous report by Ishibashi et al. stated that abdominal circumference was well MCE公司 correlated with NAFLD in men, but not in women.8 Waist circumference has been reported to be smaller in men than women and there has been considerable debate regarding whether this criterion is appropriate or not.9 There is the possibility that the amount of visceral fat might be underestimated and that the estimate may detect fewer than the actual number of women with NAFLD. In women, caution is required when the abdominal circumference is used instead of the visceral fat area. Epidemiologically, it is clear that the risk of cardiovascular diseases is increased markedly in people with multiple risk factors for life-style related diseases. In addition, Hamaguchi et al.

The use of heat-treated clotting factors in patients with haemoph

The use of heat-treated clotting factors in patients with haemophilia effectively stopped AIDS transmission; however, all licensed technologies were not equally effective at inactivating HIV. Rare transmissions of Cobimetinib manufacturer HIV occurred globally, most likely by clotting factor concentrates subjected to a single method of viral inactivation. Lacking clinical data and robust validated methods of testing inactivating technology, these seroconversions could not be predicted in advance. Achieving complete safety depended on identifying and investigating sufficient numbers of seroconversions to statistically isolate less effective methods of viral inactivation. A number of factors acted as barriers to

identifying and eliminating the residual risk. First, the high frequency of undiagnosed HIV infections already existing in the haemophilia population confused identification of possible new seroconversions due to heat-treated factors. Additional Saracatinib clinical trial factors were the continued sale of untreated products, the lack of clinical data on the effectiveness of heat-treated factors, the rarity of seroconversions and the delay in sharing vital information. Hopefully, knowledge and recognition

of these factors will improve and expedite responses to future unknown epidemics. The author stated that he has no interests which might be perceived as posing a conflict or bias. The observations expressed in this manuscript are solely the responsibility of the author based on his personal experiences. They may or may not reflect the official opinions and policies of the Federal Agencies of the United States Government identified in the manuscript. “
“Ankle fusion in patients with haemophilia is a well-accepted treatment for end-stage arthropathy. However, current published outcome data are based on small sample sizes and generally short-term follow-up. The aim of this study was to evaluate the long-term results of ankle fusion in a large group MCE of haemophilic patients treated at a single institution. The results

of 57 ankle fusions performed on 45 patients between 1971 and 2010 were reviewed retrospectively. Data were gathered for type and severity of haemophilia, HIV status, fixation technique, postoperative complications and requirement of additional surgeries. A modified American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score was calculated for 20 ankles available for follow-up. Patients were followed for a mean of 6.6 years. There were no intra-operative or immediate postoperative complications related to fusion of the ankle. The overall non-union rate was 10.4% for tibio-talar fusion and 8.3% for sub-talar fusion. This rate was reduced to 3.7% and 5.6%, respectively, after the introduction of newer surgical techniques in 1995. None of these non-unions required revision surgery.

branched PEGs and random vs site-specific attachments to clottin

branched PEGs and random vs. site-specific attachments to clotting proteins have been investigated. The most advanced of these approaches is site-specific chemical modification

of FVIII. To begin with, a large number of surface-exposed cysteine substitutions were introduced into FVIII and the specific activities of the novel proteins determined. On the basis of these initial studies, several of the cysteine-substituted molecules were then conjugated through PEG-maleimide attachments [13]. Screening of variant expression level, PEGylation yield, and functional assay identified several conjugates retaining full in vitro coagulation activity and VWF binding. Subsequent studies in haemophilic mice demonstrated a significantly extended half-life with di-PEGylated FVIII molecules and excellent in vivo efficacy compared with traditional BDD-FVIII (Fig. 2) [14]. A study in Kinase Inhibitor Library cost humans is currently ongoing. Site-directed glycoPEGylation appears to have an even greater place in terms of improving the pharmacokinetic properties of rFIX. In the first human dose trial conducted in 16 PTPs with haemophilia B [15], the half-life of N9-GP at the same dose level as their previous product was five times longer (93 h vs. 18 h), which represents a substantial difference and suggests that such a formulation of FIX could be administered at intervals of once

weekly or even longer. As always, it will be interesting to see what happens once the product reaches clinical practice and its use becomes more Liproxstatin-1 mouse widespread. Another promising approach to prolong the half-life of rFVIII and rFIX concentrates involves the generation of fusion proteins (through genetic fusion constructs) with either albumin or immunoglobulin. To date, studies using a FIX-monomeric Fc immunoglobulin fusion in a variety of animal almost models have shown that the modified FIX proteins experience a 3-

to 4-fold extension of half-life along with excellent haemostatic efficacy [13]. Despite these somewhat remarkable results in terms of strategies underway to prolong the half-life of recombinant factor concentrates, a number of unresolved questions remain.  Will prolongation of FVIII half-life prove to be as attainable as that for FIX? In closing, it is important to emphasize once again that patients with haemophilia and related diseases (VWD) currently enjoy effective and safe treatment and have a quasi normal life-expectancy. As such, any attempt of a cure (e.g. gene transfer) must be achieved at no risk to the patient. There are a number of unresolved issues with haemophilia treatment, not the least of which is the lack of availability of factor concentrates to two-thirds of the world’s population with the condition. Although the World Federation of Haemophilia is trying to tackle this issue, with great courage and with some results, it remains a formidable task.

3%) had NAFLD, 13 (22.4%) had chronic cryptogenic liver disease, 5 (8.6%) had AIH, 5 had nodular regenerative hyperplasia (NRH) of the liver,

4 (6.8%) had CDG, 2 (3.44%) had congenital hepatic fibrosis, and 2 (3.44%) had Klippel-Trénaunay-Weber syndrome with hepatic vascular malformations. Furthermore, celiac disease, chronic hepatitis C, Alagille syndrome, and sclerosing cholangitis were each present in a single case. The remaining six patients were recruited after familial screening and did not carry any mutation according to the molecular analysis of ATP7B. Ku-0059436 in vivo Liver function tests and other routine laboratory data were obtained with standard methods. The ceruloplasmin concentration in serum was measured by radial immunodiffusion (NOR-Partigen Coeruloplasmin, Behring, Marburg, Germany; normal range = 20-60 mg/dL).12 Urine samples (basal urinary click here copper and urinary copper after PCT) were collected in an acid-washed, plastic, metal-free container. PCT urinary copper was evaluated after patients ingested 500 mg of D-penicillamine at time zero and again at

12 hours while 24-hour urinary copper collection progressed.13 Copper levels in urine were determined by flame atomic absorption spectrophotometry as previously described.14 Liver biopsy was performed by the Menghini technique with a disposable biopsy set (Hepafix, Braun, Melsungen, Germany). Copper levels in dried liver tissue were determined by flame atomic absorption spectroscopy according to Kingston and Jassie15 (normal cAMP range = 6-50 μg/g of dry weight). All slides were examined by the same pathologist, and lesions were evaluated according to the recommendations of Batts and Ludwig.16 For the molecular analysis of the ATP7B gene, DNA extraction and polymerase chain reaction were carried out with the standard methods by Dr.

Georgios Loudianos (Ospedale Regionale per le Microcitemie, Cagliari, Italy). With single-strand conformational polymorphism and sequencing methods, patients were analyzed for the 12 exons (5, 6, 8, 10, and 12-19) on which most mutations reside according to previous studies of the Italian continental population. DNA samples not completely characterized by the first step of analysis or those found to have a new missense mutation were further analyzed for the remaining exons of the ATP7B gene by single-strand conformational polymorphism and sequencing analysis.17 Continuous variables (ceruloplasmin, urinary copper, and liver copper) were presented as numbers of patients, means, medians, and standard deviations, whereas discrete variables (clinical manifestations at presentation and the presence or absence of KF rings) were presented as percentages. Normally distributed continuous variables were presented as means and standard deviations and were compared between groups by analysis of variance with post hoc testing (Scheffe’s test).

Tuber periderm responses to infection were limited, yet US-8 isol

Tuber periderm responses to infection were limited, yet US-8 isolates infected the periderm more often than US-22 isolates. There were significant differences among the cultivars tested but cv. Jacqueline Lee was the most resistant overall. Although isolates of P. infestans genotype US-22 were less aggressive in comparison with US-8 isolates, US-22 isolates still infected

potato tubers and were as aggressive us US-8 isolates on some cultivars. Management of late blight caused by isolates of US-22 through host selleck inhibitor resistance may be feasible but imposes a different set of criteria for consideration from those that US-8 imposed. The oomycete Phytophthora infestans (Mont.) de Bary is the causal agent of late blight, which is the most devastating disease on potato

worldwide (Fry 2008). Because the disease was first reported in the 1840s (de Bary 1876), outbreaks have occurred intermittently with different degrees of impact. Since the global re-emergence of late blight in the 1980s (Fry and Goodwin 1997b), new and more aggressive genotypes have impacted potato (Hu et al. 2012) and tomato crops (Chowdappa et al. 2013). One genotype designated as US-1 dominated the SAR245409 global P. infestans population until the last decade of the 20th century. Several genotypes then appeared and caused comparatively more severe losses than US-1 (Spielman et al. 1991; Goodwin et al. 1994; Fry and Goodwin 1997a; Fry 2008). Vleeshouwers et al. (2010) documented the recent impact of late blight during the epidemics in the United States and Europe from 2005 to 2008, showing the capacity of this pathogen to adapt and evolve Pregnenolone causing disease. The genotype US-8 (mating type

A2, mefenoxam-insensitive, GPI 100/110/122) has been described as one of the most aggressive genotypes to date, due to the aggressiveness of isolates on foliage (Goodwin et al. 1996; Kirk et al. 2001a). US-8 isolates also proved more aggressive on potato tubers causing faster appearance of tuber rot symptoms than isolates observed previously (Kirk et al. 2009, 2010). The US-8 genotype quickly became predominant in potato cropping systems following its first detection in 1989 in north and central Mexico (Goodwin et al. 1992, 1998). The appearance of US-8 and the displacement of US-1 were characterized by an increase in the severity of tuber blight (Lambert and Currier 1997). A similar case was observed recently in Europe: the genotype 13_A2, also known as Blue-13, appeared during 2006–2008 and became the dominant genotype in Great Britain and mainland Europe (Lees et al. 2008; Cooke et al. 2011, 2012) and since then in India (Chowdappa et al. 2013). Genotype 13_A2 characteristically has an increased aggressiveness on potato foliage and tubers in comparison with previous genotypes detected in the region (Cooke et al. 2011).

Cell lysates were analyzed by the dual luciferase assay (Promega)

Cell lysates were analyzed by the dual luciferase assay (Promega) on a luminometer. To assess the activity of IKK, IKK was immunoprecipitated by IKKα antibody and protein G-Sepharose, and the assay was performed at 30°C for 1 hour in buffer

containing 20 mM Tris HCl, pH 7.5, 20 mM MgCl2, 2 mM dithiothreitol, 20 μM ATP, 2 μg GST-IκBα, and [γ-32P]ATP. The reaction was stopped by addition of Laemmli buffer and was resolved by 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) followed by a transfer onto a membrane for imaging. Whole cell extracts were prepared as described.8 Equal amounts of Galunisertib molecular weight the extract (20 μg) were separated by 8%-15% SDS-PAGE and the proteins were transferred to nitrocellulose membranes (Bio-Rad, Hercules, CA). MeCP2, type I collagen, and β-actin were detected by incubating with rabbit polyclonal anti-MeCP2 (1:1,000) (Abcam), anti-type I collagen (1:4,000), and anti-β-actin (1:5,000) primary antibodies (Santa Cruz Biotechnology) in TBS (100 mM Tris-HCl,

1.5 M NaCl, pH 7.4) with 5% nonfat milk overnight at 4°C followed by incubation with horseradish peroxidase-conjugated goat antirabbit secondary antibodies (1:4,000) (Sigma) at room temperature for 2 hours. The antigen-antibody complexes’ chemiluminescence was detected using the ECL detection kit (Pierce). Talazoparib cell line For assessing Pparγ epigenetic regulation, carrier ChIP was performed using Raji cells as the source of carrier chromatin. For Galeterone native ChIP, 20 μg of HSC chromatin was mixed with 80 μg of Raji cell chromatin. For crosslink ChIP, Raji cells (1.4 × 107 cells) were mixed with HSCs (0.2 × 106 cells) and fixed with 1% formaldehyde on the rotating platform for 5-10 minutes at room temperature followed by addition of glycine to a final concentration of 0.125 M. After lysis of the cells with SDS buffer (1% SDS, 10 mM EDTA, 50 mM Tris-HCl, pH 8.1) with protease inhibitors, the

lysates were sonicated and snap-frozen in aliquots. For chromatin IP, diluted samples were first precleared using protein G-agarose beads and then incubated with antibody against Ser2P RNApolyII, MeCP2, H3K27me2, H3K4me2, and H3Kacetylated (Abcam) at 1 μg/μL at 4°C overnight followed by precipitation with protein G-agarose beads. After elution of immunoprecipitated complex, crosslinking was reversed with 5 N NaCl and proteins digested with protease K. Extracted chromatin was subjected to real-time PCR using the primers flanking a segment within Pparγ promoter or exon as described.17 Ct values of the samples with nonimmune IgG were subtracted and compared to their respective input Ct values. The aqueous YGW extract (350 mg/mL in PBS) was applied to size exclusion chromatography using Super Prep Grade gel in XK 16/70 column (Amersham Pharmacia Biotech, Piscataway, NJ) and PBS as a mobile phase solvent.

These commonly occur in pollutants, food preservatives, and pesticides.26 Atmospheric concentrations of pollutants are known to exhibit seasonal variation, providing support for a possible link with the onset of PBC.27, 28 Diet often varies seasonally and may be associated with the onset of PBC. There are Inhibitor Library screening several possible mechanisms, such as consumption of fresh vegetables contaminated with pesticides or infection with a specific bacterium whose prevalence varies seasonally. In conclusion, this is the first study, in a large population using reliable methodology, to find seasonal variation among

cases of PBC. There was a highly statistically significant excess of cases in the month of June, and the pattern exhibited a sinusoidal form of occurrence. These novel results provide further evidence for the role of one or more transient environmental agents in etiology, at least in some patients. Candidate agents include infections, atmospheric pollution, or dietary factors. “
“Glycogen storage disease (GSD) type Ia is caused by a deficiency

However, little is known about GSD type Ia patients with HCA who develop cholangiocellular carcinoma (CCC). Here, we report for the first time, a patient with GSD type Ia with HCA, in whom intrahepatic

“The development of portal fibrosis following the iron loading of hepatocytes is the first stage of fibrogenesis Protein kinase N1 in hereditary hemochromatosis. In other chronic liver diseases it has been shown that a ductular reaction (DR) appears early, correlates with fibrosis progression, and is a consequence of activation of an alternative pathway of hepatocyte replication. This study was designed to investigate the presence of the DR in hemochromatosis and describe its associations. Liver biopsies from 63 C282Y homozygous patients were assessed for hepatic iron concentration (HIC) and graded for iron loading, fibrosis stage, steatosis, and inflammation. Immunostaining allowed quantification of the DR, hepatocyte senescence and proliferation, and analysis incorporated clinical data. Hepatocyte senescence was positively correlated with HIC, serum ferritin, and oxidative stress. A DR was demonstrated and occurred prior to histological fibrosis. HIC, age, hepatocyte senescence and proliferation, portal inflammation, and excessive alcohol consumption all had significant associations with the extent of the DR. In multivariate analysis, iron loading, hepatocyte replicative arrest, and portal inflammation remained independently and significantly associated with the DR. Of factors associated with fibrosis progression, the DR (odds ratio [OR] 10.86 P < 0.

To study the biological effect of miR-216a elevation further in e

To study the biological effect of miR-216a elevation further in early hepatocarcinogenesis, we tried to identify its target

gene(s) in hepatocytes. By comparing the gene expression profile between HepG2 cells infected with lenti-miR-216a and with lenti-si-GFP control viruses, the results from our microarray analysis indicated the increase in proliferation and migration activities as putative biological functions affected by the elevation of miR-216a (Supporting Table 2S). As predicted by the miRanda algorithm (MicroRNA.org, http://www.microrna.org, September 2008 release), the tumor suppressor gene TSLC1/IGSF4/CADM1 (Tumor suppressor in lung cancer 1/Immunoglobulin superfamily 4/Cell adhesion molecule 1) was pointed out as one putative B-Raf inhibitor drug target for miR-216a (ranked

second on the list), with major functions to control the cell proliferation and migration activities. Three putative miR-216a target sites were predicted in the 3′ untranslated region (UTR) of the TSLC1 gene, targeting to nucleotide 400–421 (target site 1), 736–759 (target site 2), and 1155–1177 (target site Depsipeptide datasheet 3), respectively (Fig. 5A). Two reporter constructs were established to evaluate the regulation of TSLC1 by miR-216a through these putative target sites. One is pGL3-TSLC1-3′ UTR(WT), which contains the wildtype target sites; the other is pGL3-TSLC1-3′ UTR(Mut), which contains the mutated target sites (Fig. 5A). HepG2 cells expressing either reporter constructs Carnitine palmitoyltransferase II or the pGL3-vector (as a control) were infected with lenti-si-GFP or lenti-miR-216a, with the aim of evaluating the effect of miR-216a on the reporter activity. As a control, the cells transfected with pGL3-vector were not affected by either lenti-si-GFP or lenti-miR-216a (Fig. 5B, lanes 1-3). In contrast, infection with lenti-miR-216a (≈5-fold increase of miR-216a expression, revealed by RT-qPCR) led to a decrease of luciferase activity in cells transfected with TSLC1-3′ UTR(WT) compared with that caused by lenti-si-GFP (Fig. 5B, lane 6 versus lane 5). This effect was diminished when the three putative

target sites were mutated in cells transfected with the TSLC1-3′ UTR-mut reporter construct (Fig. 5B, lane 9 versus lane 6). The results suggested that through these three putative target sites within 3′ UTR, miR-216a can regulate the expression of TSLC1. Moreover, we evaluated the effect of elevated miR-216a on the endogenous TSLC1 protein. Relative to the cells infected with lenti-si-Luc or lenti-si-GFP control viruses, TSLC1 protein was decreased ≈50% in cells infected with lenti-miR-216a (Fig. 5C), suggesting the targeting of TSLC1 by miR-216a. To examine any biological functions for the elevation of miR-216a in hepatocytes, we focused on the proliferation and migration activities due to the well-characterized function of its target gene, TSLC1.

2 log10IU/mL was the optimal cut-off for characterizing cholestatic hepatitis C. All of the patients were serum HCV RNA negative after treatment with pegylated interferon and ribavirin and all the patients are alive. Early extensive viremia, but not the rs8099917 genotype, was the only predictor for cholestatic hepatitis C after LDLT. “
“Liver and pancreatic cancers are both highly lethal diseases with limited to no therapeutic options for patients. Recent studies suggest that deregulated autophagy plays a role in the pathogenesis of these diseases by perturbing cellular homeostasis and

laying the foundation for disease development. While RAD001 accumulation of p62 upon impaired autophagy has been implicated in hepatocellular carcinoma, its role in pancreatic ductal adenocarcinoma remains less clear. This review will focus on recent studies illustrating the role of autophagy in liver and pancreatic cancers. The relationships between autophagy, nuclear factor-κB signaling AZD9668 mouse and obesity in hepatocellular carcinoma will be discussed, as well as the dual role of autophagy in pancreatic ductal adenocarcinoma. “
“Host cellular factor apolipoprotein B messenger RNA (mRNA)-editing enzyme

catalytic polypeptide-like 3G (hA3G) is a cytidine deaminase that inhibits a group of viruses including human immunodeficiency virus-1 (HIV-1). In the continuation of our research on hA3G, we found that hA3G stabilizing compounds significantly inhibited hepatitis C virus (HCV) replication. Therefore, this study investigated the role of hA3G in HCV replication. Introduction of external hA3G into HCV-infected Huh7.5 human hepatocytes inhibited HCV replication; knockdown of endogenous hA3G enhanced HCV replication. Exogenous HIV-1 virion infectivity factor (Vif) decreased intracellular hA3G and therefore enhanced HCV proliferation, 3-mercaptopyruvate sulfurtransferase suggesting that the presence of Vif might

be an explanation for the HIV-1/HCV coinfection often observed in HIV-1(+) individuals. Treatment of the HCV-infected Huh7.5 cells with RN-5 or IMB-26, two known hA3G stabilizing compounds, increased intracellular hA3G and accordingly inhibited HCV replication. The compounds inhibit HCV through increasing the level of hA3G incorporated into HCV particles, but not through inhibiting HCV enzymes. However, G/A hypermutation in the HCV genome were not detected, suggesting a new antiviral mechanism of hA3G in HCV, different from that in HIV-1. Stabilization of hA3G by RN-5 was safe in vivo. Conclusion: hA3G appears to be a cellular restrict factor against HCV and could be a potential target for drug discovery. (HEPATOLOGY 2011;) Human APOBEC3G (apolipoprotein B messenger RNA [mRNA]-editing enzyme catalytic polypeptide-like 3G, hA3G) belongs to the APOBEC superfamily, which covers at least 10 members sharing a cytidine deaminase motif (a conserved His-X-Glu and Cys-X-X-Cys Zn2+ coordination motif).

28 Three different constructs were selected, each carrying the mutant (mt) viral isolate representative of the dominant HBV population infecting patients 14, 4, and 8 (pHBV-mtpreS1, pHBV-mtpreS2, and pHBV-mtS, respectively) (Fig. 1A). Linear HBV monomers were released from pHBV-mtpreS1, pHBV-mtpreS2, and pHBV-mtS constructs and from plasmid pUC-HBV (genotype D), used as a WT control, by way of cleavage with the restriction enzyme

SapI (New England Biolabs, Ipswich, MA). After digestion, linear HBV genomes were gel-purified and see more transiently transfected into HepG2 cells using the FuGENE transfection reagent (Roche Applied Science). Briefly, HepG2 cells were seeded at a density of 1 × 106 cells in 100-mm-diameter Petri dishes and transfected 24 hours later with 2 μg of SapI-digested HBV DNA. Culture medium was changed 1 day after transfection, and cells harvested 1 day later. All transfections included 1 μg of reporter plasmid expressing enhanced green fluorescence protein to assess transfection efficiency. All transfection experiments were done at least three times, each time using independently prepared HBV DNA (Qiagen Maxi Preparation Kit). Statistical analysis was performed selleckchem by SPSS version

11.0 software package (SPSS Inc, Chicago, IL). A nonparametric approach was used to examine variables showing absence of a normal distribution, as verified by the Kolmogorov-Smirnov test. The interdependence between numerical variables was performed by the use of the Spearman

rank correlation test, whereas the Mann-Whitney test was applied to perform comparisons of continuously distributed variables between two independent groups. To evaluate the association between categorical variables, the log-likelihood ratio test was applied. P < 0.05 were considered as statistically significant. Quantification analyses showed a significant positive correlation Urease between HBsAg (median, 2.3 × 103 IU/mL; range, 56-9.4 × 104 IU/mL) and HBV DNA (median, 2.5 × 105 IU/mL; range, 482-2.4 × 108 IU/mL) serum levels (r = 0.416; P = 0.008) in the study population (Fig. 2A). However, when HBeAg-positive and HBeAg-negative subgroups of patients were separately examined, no correlation was found between HBsAg and HBV DNA levels in either subgroup (Fig. 2B,C), likely because of the limited number of individuals included in each of them. HBeAg-positive patients had significantly higher serum HBV DNA levels (median, 1 × 108 IU/mL; range, 2.1 × 104-1.1 × 108; P = 0.017) compared to HBeAg-negative cases (median, 2.3 × 106 IU/mL; range, 482-2.3 × 108), whereas the median HBsAg titer did not differ significantly between the two subgroups (4.9 × 103 IU/mL versus 2 × 103 IU/mL, P = 0.27).
