Erectile dysfunction in patients with liver disease related to chronic hepatitis B

Background/Aims

Despite sexual function making an important contribution to the quality of life, data on erectile function are relatively scant in patients with chronic liver disease. We evaluated the prevalence of and risk factors for erectile dysfunction (ED) in patients with liver disease related to hepatitis B, especially among those with chronic hepatitis B (CHB) or early-stage cirrhosis.

Methods

In total, 69 patients (35 with CHB and 34 with hepatitis-B-related liver cirrhosis [HBV-LC]) aged 40-59 years were analyzed. Child-Pugh classes of A and B were present in 30 (88.2%) and 4 (11.8%) of the patients with HBV-LC, respectively. The erectile function of the patients was evaluated using the Korean version of IIEF-5.

Results

The prevalence of any ED was 24.6% for all patients, and 8.6% and 41.2% for those with CHB and HBV-LC, respectively (P=0.002). While there was only one (2.9%) CHB patient for each stage of ED, mild, moderate, and severe ED stages were seen in three (8.8%), one (2.9%), and ten (29.4%) of the HBV-LC patients, respectively. Multiple regression analysis identified the type of liver disease (P=0.010), hypertension (P=0.022), score on the Beck Depression Inventory (P =0.044), and the serum albumin level (P=0.014) as significant independent factors for the presence of ED.

Conclusions

The prevalence of ED was significantly higher in patients with early-stage HBV-LC than in those with CHB. Therefore, screening male patients with early viral cirrhosis for ED and providing appropriate support are needed, especially when the cirrhosis is accompanied by hypertension, depression, or a depressed level of serum albumin.     

The factors associated with longitudinal changes in liver stiffness in patients with chronic hepatitis B

Background/Aims

Liver stiffness (LS) as assessed by transient elastography (TE) can change longitudinally in patients with chronic hepatitis B (CHB). The aim of this study was to identify the factors that improve LS.

Methods

Between April 2007 and December 2012, 151 patients with CHB who underwent two TE procedures with an interval of about 2 years were enrolled. Ninety-six of the 151 patients were treated with nucleos(t)ide analogues [the antiviral therapy (+) group], while the remaining 55 patients were not [the antiviral therapy (-) group]. The two groups of patients were stratified according to whether they exhibited an improvement or a deterioration in LS during the study period (defined as an LS change of ≤0 or >0 kPa, respectively, over a 1-year period), and their data were compared.

Results

No differences were observed between the antiviral therapy (+) and (-) groups with respect to either their clinical characteristics or their initial LS. The observed LS improvement was significantly greater in the antiviral therapy (+) group than in the antiviral therapy (-) group (-3.0 vs. 0.98 kPa, P=0.011). In the antiviral therapy (+) group, the initial LS was higher in the LS improvement group (n=63) than in the LS deterioration group (n=33; 7.9 vs. 4.8 kPa, P<0.001). However, there were no differences in any other clinical characteristic. In the antiviral therapy (-) group, the initial LS was also higher in the LS improvement group (n=29) than in the LS deterioration group (n=26; 8.3 vs. 6.5 kPa, P=0.021), with no differences in any other clinical characteristic.

Conclusions

A higher initial LS was the only factor associated with LS improvement in patients with CHB in this study.     

Serum hepatitis B surface antigen levels correlate with high serum HBV DNA levels in patients with chronic hepatitis B: a cross-sectional study

Purpose: The hallmark of chronic hepatitis B (CHB) infection is the presence of hepatitis B surface antigen (HBsAg) positivity for at least 6 months. Recently, serum levels of HBsAg have been compared with serum HBV DNA as a surrogate marker to monitor CHB patients. However, data correlating these two markers are scarce. Hence, the present study was done to correlate HBV DNA with HBsAg in CHB patients. Materials and Methods: Consecutive patients of CHB were included. HBV DNA was measured by real-time polymerase chain reaction (PCR). Serum HBsAg was measured by Architect HBsAg. Results: Of the 198 patients enrolled, 166 fulfilled the inclusion criteria (mean age 43 ± 14 years, 87% males) and the median HBV DNA was 1.7 × 10³ (range 6.0–1.1 × 10⁸) IU/ml. Median HBsAg was 8.7 × 10³ (range 5.0–3.2 × 10⁵) IU/ml. Overall correlation between HBV DNA and HBsAg was weak but significant (Spearman ρ = 0.443, P < 0.01). Correlation in HBe antigen-positive group was better (ρ = 0.402, P < 0.01) in comparison to HBe antigen-negative group (ρ = 0.193 P = 0.05). Good correlation existed in treatment-naïve group (ρ = 0.538, P < 0.01). Correlation was regardless of normal or raised alanine transaminase (ALT). Eighty (48%) patients had high HBV DNA (≥2000 IU/ml). Correlation in high DNA group was significant (P < 0.01). The best cut-off of HBsAg for diagnosing high DNA is 3.36 ×10³ IU/ml. Conclusions: Serum HBsAg correlates with HBV DNA in CHB patients, especially in high serum HBV DNA, HBe antigen-positive and treatment-naïve group. HBsAg levels can be used for predicting high serum HBV DNA levels.

Serum liver fibrosis markers discriminate significant liver inflammation in chronic hepatitis B patients with normal or near-normal alanine aminotransferase

Chronic liver inflammation caused by chronic hepatitis B virus (CHB) infection leads to liver cirrhosis and hepatocellular carcinoma. Recently, the role of alanine aminotransferase (ALT) as a predictor of liver inflammation has been questioned. The aim of this study was to investigate the utility of noninvasive fibrosis markers including hyaluronic acid (HA), collagen type IV (CIV), N-terminal propeptide of type III procollagen (PIIINP), and laminin (LN) in identifying significant liver inflammation in patients with CHB, especially in patients with normal or near-normal ALT. A total of 242 CHB patients who underwent liver biopsy were enrolled. The serum levels of ALT, aspartate aminotransferase, HA, CIV, PIIINP, and LN were quantified and the relationship between histological staging and serum markers was systematically analyzed. Serum CIV, PIIINP, HA, and LN levels increased significantly along with the increasing severity of liver inflammation. Multivariate analysis showed that CIV and LN were independently associated with significant inflammation. CIV, PIIINP, HA, and LN levels were found to have high diagnostic values for predicting significant inflammation in patients with CHB (area under the curve, AUC = 0.807, 0.795, 0.767, and 0.703, respectively). The combined index for the identification of significant inflammation, including CIV, PIIINP, HA, and LN levels, significantly improved diagnostic performance (AUC = 0.851). Moreover, the combined index also achieved excellent diagnostic accuracy (AUC = 0.861) in patients with CHB with normal or near-normal ALT. In conclusion, the combined index may be a strong indicator for discriminating significant liver inflammation, especially in patients with CHB with normal or near-normal ALT.

Response to hepatitis B vaccination in patients with liver cirrhosis

Hepatitis B vaccination is strongly recommended for all infants and children but also for adults who are at risk of HBV infection. Attempts to immunize patients with liver cirrhosis have been proven relatively ineffective, and several strategies have already been used to improve the immune response in this group. The primary aim of this review is to examine, discuss, and summarize the immunogenicity of hepatitis B vaccination in patients with liver cirrhosis. MEDLINE search identified 11 studies (n = 961). The dose of the vaccine and the schedule of the vaccination varied. The response rates to the HBV vaccination ranged from 16% to 87% among patients with cirrhosis regardless of the number and vaccine dose. In particular, patients who received the standard dose of vaccination achieved seroprotection rates ranged from 16% to 79% (mean response rate 38%) and those who received a double dose achieved relatively better seroprotection rates (range: 26%‐87%; mean response rate 53%). The overall mean response rate to the HBV vaccination was 47%. In conclusion, cirrhotic patients achieve lower seroprotection rates after the completion of HBV vaccination series. Several strategies have tried to improve the immunogenicity; however, there is a great need for additional studies to further explore (1) the immune response in relation to poor vaccination responsiveness confounding factors, (2) novel strategies to improve immunogenicity, and (3) the immune mechanism underlying the differences in response rates to HBV vaccination.

Histology and virus expression in the liver: A prognostic puzzle in chronic hepatitis B

Summary Forty chronic untreated paediatric carriers of hepatitis B virus (HBV) infection, with no other causes of liver disease, were biopsied on presentation, when the disease was in the active viral replication phase. After a period ranging from 1 to 13 years, all patients underwent a control biopsy. At the time of the last biopsy, 31 of the patients were anti-HBe positive, whereas 9 persisted in the active replication phase. In this latter phase, necrotic and inflammatory lesions and the presence of nuclear HBcAg were found significantly more frequently than when replication had terminated. The necrotic and inflammatory lesions detected in the first biopsy of patients who subsequently underwent antiHBe seroconversion were significantly more severe than in patients failing to reach seroconversion. All patients who maintained viral replication showed generalized nuclear reactivity for HBcAg on presentation; such reactivity was also found in 16 of 31 (52%) patients who reached anti-HBeAg seroconversion. All these cases had piecemeal necrosis (PMN) in the biopsy. PMN may therefore be considered as a positive prognostic factor in that it identifies those patients who may seroconvert with significant remission of liver disease     

Development and validation of a potential biomarker to improve the assessment of liver fibrosis progression in patients with chronic hepatitis B

We aimed to develop and validate a novel combined score to improve the assessment of liver fibrosis progression in patients with chronic hepatitis B (CHB). In this study, a total of 331 CHB patients from three cohorts who underwent liver biopsy were enrolled, and the Scheuer system was used for liver fibrosis classification. The combined score was derived by principal component analysis of key differentially expressed genes. For significant liver fibrosis (≥S2), the areas under the receiver operating characteristics curves (AUROCs) of the combined score were 0.838, 0.842, and 0.881 in the three cohorts, respectively. And for advanced liver fibrosis (≥S3), the AUROCs were 0.794, 0.801, and 0.901, respectively. Compared with the results of AUROCs for aspartate aminotransferase≥to≥platelet ratio (APRI) and fibrosis index based on four factors (FIB-4) in the validation cohorts, better clinical diagnostic value for assessing the progression of liver fibrosis was found in the combined score. Additionally, univariate ordered logistic regression analysis indicated that the combined score could serve as a more superior and stable risk factor than APRI and FIB-4 in the assessment of liver fibrosis. For CHB patients with normal alanine aminotransferase (ALT), our results further emphasized the diagnostic value of the combined score for significant fibrosis (≥S2) and advanced fibrosis (≥S3). Moreover, it was found that patients with the high combined score, who were associated with the advanced fibrosis stage, had higher levels of drug sensitivity and immune checkpoint expression. In conclusion, the novel combined score could serve as a potential biomarker and contribute to improving the assessment of fibrosis stage in CHB patients.

Serum fibrosis index-based risk score predicts hepatocellular carcinoma in untreated patients with chronic hepatitis B

Background/AimsSerum fibrosis scores comprised of common laboratory tests have high utility to assess severity of liver fibrosis. We aimed to derive and validate a hepatocellular carcinoma (HCC) risk score based on serum fibrosis scores to predict HCC in treatment-naïve chronic hepatitis B (CHB) patients.MethodsFifteen thousand one hundred eighty-seven treatment-naïve adult CHB patients were identified to form the training cohort in this retrospective study. Individual fibrosis score was included to construct a new HCC prediction score. The score was externally validated in an independent treatment-naïve Korean CHB cohort.Results180/15,187 patients (1.2%) in training cohort and 47/4,286 patients (1.1%) in validation cohort developed HCC during a mean follow-up of 52 and 50 months, respectively. The newly developed HCC risk score, Liang score, is composed of gender, age, hepatitis B virus DNA, fibrosis-4 (FIB-4) index, and ranges from 0 to 22. Area under the time-dependent receiver operating characteristic curve of Liang score was 0.79 (95% confidence interval, 0.70–0.89). A cutoff value of nine provided an extremely high negative predictive value of 99.9% and high sensitivity of 90.0% at 5 years in the validation cohort. Patients with Liang score ≤9 had HCC incidence <0.2% per year in both training and validation cohorts, in whom HCC surveillance might be exempted.Conclusion: A novel HCC risk score, Liang score, based on FIB-4 index, is applicable and accurate to identify treatment-naïve CHB patients with very low risk of HCC to be exempted from HCC surveillance.

Peroxidase-anti-peroxidase detection of hepatitis B surface and core antigen in liver biopsy specimens from patients with chronic type B hepatitis

Liver biopsy specimens from 58 American patients with chronic type B hepatitis were investigated for the presence and distribution of the hepatitis B core (HBcAg) and surface (HBsAg) antigens by peroxidase-anti-peroxidase techniques. HBsAg was detected in 43 (77%) and HBcAg in 52 (90%) patients. HBcAg was present in 50 of 51 (98%) patients with hepatitis B e antigen (HBeAg) but in only two of seven (29%) of patients with antibody to HBeAg (anti-HBe). There was no correlation between severity of hepatitis or height of aminotransferase activities and the amount of HBsAg or HBcAg in hepatocytes but there was a positive correlation between amount of HBcAg and height of HBV-DNA and DNA polymerase activity in serum. Follow-up liver biopsies, taken 1 to 3 yr later, were available from 39 patients. HBcAg remained detectable in 25 of 26 patients with persistence of HBeAg but disappeared in 12 patients who had lost HBeAg. In nine patients, HBcAg was cytoplasmic as well as nuclear in distribution. Seven of these patients had an intense lobular hepatitis with marked elevations in aminotransferase activities. These findings indicate that the amount of HBcAg in liver correlates with the amount of serum hepatitis B virus as quantified by serum levels of DNA polymerase and HBV-DNA. The amount of nuclear HBcAg does not correlate with the severity of the liver disease, but the presence of cytoplasmic HBcAg usually reflects an active and severe ongoing hepatitis.     

The best predictive model for hepatocellular carcinoma in patients with chronic hepatitis B infection

Chronic hepatitis B (CHB) seriously threatens human health. About 820,000 deaths annually are due to related complications such as hepatitis B and hepatocellular carcinoma (HCC). Recently, the use of oral antiviral agents has significantly improved the prognosis of patients with CHB infection and reduced the risk of HCC. However, hepatitis B virus still remains a major factor in the development of HCC, raising many concerns. Therefore, numerous studies have been conducted to assess the risk of HCC in patients with CHB infection and many models have been proposed to predict the risk of developing HCC. However, as each study has different models for predicting HCC development that can be applied depending on the use of antiviral agents or the type of antiviral agents, it is necessary to properly understand characteristics of each model when using it for the evaluation of HCC in patients with CHB infection. In addition, because different variables such as host factor, viral activity, and cirrhosis are used to evaluate the risk of HCC development, it is necessary to assess the risk by carefully verifying which variables are used. Recently, studies have also evaluated the risk of HCC using risk prediction models through transient elastography and artificial intelligence (AI) system. These HCC risk predication models are also noteworthy. In this review, we aimed to compare HCC risk prediction models in patients with CHB infection reported to date to confirm variables used and specificity between each model to determine an appropriate HCC risk prediction method.     

miR-34a promotes liver fibrosis in patients with chronic hepatitis via mediating Sirt1/p53 signaling pathway

PurposeThis research aimed to explore the correlation between miR-34a expression in peripheral blood and clinical characteristics of patients with chronic hepatitis C (CHC) as well as the diagnostic and prognostic values of serum miR-34a in CHC.MethodsSerum samples of 41 CHC patients and 18 normal participants were collected to examine the expression levels of miR-34a using qRT-PCR. The changes of serum TBA, liver enzyme AST and ALT were also determined by enzyme colorimetry and rate method. The levels of serum fibrotic markers hyaluronic acid (HA), type III procollagen (PCIII), type IV collagen (IV-C) and laminin (LN) were detected by radioimmunoassay. Degree of liver fibrosis was examined by liver biopsy. Western blot analysis was used to investigate the expression of ac-p53, p53 and Sirt1 in the liver tissues of CHC patients.ResultsMiR-34a was significantly increased in the serum of CHC patients than that in healthy participants, and serum miR-34a was correlated with liver fibrosis index. Serum TBA, AST and ALT levels, and AST/ALT ratios in patients with CHC were increased with increasing degree of fibrosis, and were positively associated with serum miR-34a. Furthermore, the liver tissues of CHC patients showed low Sirt1 protein expression and highly ac-p53 protein expression.ConclusionsSerum miR-34a in patients with CHC could promote liver fibrosis through mediating the Sirt1/p53 pathway and might function as pivotal biomarker on the prognosis and diagnosis of CHC patients.
