Abstract
The population of inactive HBsAg carriers (IHCs) is enormous, and it is often overlooked because of the insidious progression and mild severity of the disease. With the continuous enrichment and consolidation of research evidence, the population of IHC has obtained a high clinical cure rate through a treatment strategy based on pegylated interferon α and a stronger treatment intention. This article reviews the definition and treatment recommendations of IHCs in current domestic and international guidelines, as well as the disease progression and clinical cure research progress, so as to provide a reference and basis for scientific management and rational therapeutics.

Abstract
BACKGROUND AND AIMS Hepatitis D virus (HDV) infection causes the most severe form of chronic viral hepatitis. However, it is still unclear to what extent the underlying cirrhosis may contribute to disease progression. The aim of this study was to compare the long-term outcome of HDV infection with HBV monoinfection in a single-center cohort of both non-cirrhotic and cirrhotic patients. METHOD We retrospectively studied 175 patients with chronic hepatitis D (CHD) who were followed for at least 6 months (median of 6.3 (0.6-23.6) years). In addition, we selected 175 patients with HBV monoinfection (CHB) who were matched for gender, age, region of origin, HBeAg status, and bilirubin. Liver-related clinical end points were defined as hepatic decompensation (ascites, encephalopathy, variceal bleeding), liver transplantation, HCC, or liver-related death. RESULTS Clinical complications developed earlier (4.6 vs. 6.2 years) and more frequently (35.4% vs. 12.6%, p < 0.01) in CHD patients. In a multivariate Cox regression, HDV infection was independently associated with the development of end points (p < 0.01; HR: 3.0; 95% CI 1.4-6.4). However, in cirrhotic patients there were no significant differences between HBV and HDV in the development of end points. Besides, CHB patients with cirrhosis developed more frequently HCC (35.5%) than CHD patients with cirrhosis (18.5%). CONCLUSION Our results confirmed that HDV leads to a faster progression to cirrhosis compared to HBV. However, once cirrhosis is present, not HDV but the underlying cirrhosis is the dominate intrinsic risk factor for the development of liver-related end points and for the progression to HCC.

Abstract
BACKGROUND Anti-hepatitis B virus (HBV) treatment uses tenofovir disoproxil fumarate (TDF) along with Pegylated-interferon-alpha (Peg-IFN-α), which is more effective than TDF/Peg-IFN-α monotherapy. We have previously shown that interleukin-1beta (IL-1β) is related to the effectiveness of IFN-α treatment in chronic hepatitis B (CHB) patients. The aim was to investigate the expression of IL-1β in CHB patients treated with Peg-IFN-α combination with TDF and TDF/Peg-IFN-α monotherapy. METHODS Huh7 cells infected with HBV were stimulated by Peg-IFN-α and/or Tenofovir (TFV) for 24h. A single-center cohort study of prospective recruitment of CHB patients: untreated CHB (Group A), TDF combined with Peg-IFN-α therapy (Group B), Peg-IFN-α monotherapy (Group C), TDF monotherapy (Group D). Normal donors served as controls. The clinical datas and blood of patients were collected at 0, 12, and 24 weeks. According to the early response criteria, Group B and C were divided into two subgroups: the early response group (ERG) and the non-early response group (NERG). Stimulation of HBV-infected hepatoma cells with IL-1β to validate the antiviral activity of IL-1β. To test the blood sample, cell culture supernatant, and cell lysates and to assess the expression of IL-1β and HBV replication levels in various treatment protocols, Enzyme-Linked Immunosorbent Assay (ELISA) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) were used. SPSS 26.0 and GraphPad Prism 8.0.2 software were used for statistical analysis. P values < 0.05 was considered to be statistically significant. RESULTS In vitro experiments, Peg-IFN-α plus TFV treatment group expressed higher IL-1β and inhibited HBV more effectively than monotherapy. Finally, 162 cases were enrolled for observation (Group A (n = 45), Group B (n = 46), Group C (n = 39), and Group D (n = 32)), and normal donors (n = 20) were enrolled for control. The early virological response rates of Group B, C, and D were 58.7%, 51.3%, and 31.2%. At 24 weeks, IL-1β in Group B(P = 0.007) and C(P = 0.034) showed higher than at 0 week. In Group B, the IL-1β showed an upward trend at 12w and 24w in the ERG. IL-1β significantly reduced HBV replication levels in hepatoma cells. CONCLUSION The increased expression of IL-1β may enhance the efficacy of TDF combined with Peg-IFN-α therapy in achieving an early response for CHB patients.

Abstract
PURPOSE To report treatment outcomes of orbital tumors associated with Erdheim-Chester disease and to highlight the importance of systemic work-up in patients presenting with bilateral proptosis. PATIENTS AND METHODS Three patients with Erdheim-Chester disease, whose initial manifestation was bilateral proptosis, were retrospectively studied. The course of onset, clinical, imaging and histopathological features, systemic associations and response to treatment were reviewed. The main outcome measures were Hertel measurements and orbital tumor regression on imaging studies. RESULTS All patients presented with bilateral non-pulsatile proptosis resistant to retropulsion and headeache without specific localization. Magnetic resonance imaging studies showed bilateral intraconal orbital tumors. Incisional biopsy of these tumors demonstrated CD68+, CD1a-, and S100- histiocytic infiltrates consistent with the diagnosis of Erdheim-Chester disease. The BRAFV600E mutation was found in all cases. Systemic work-up revealed asymptomatic bony involvement in the lower extremities, perirenal fibrosis, central nervous system and cardiac involvement. All patients initially received pegylated interferon-α2a, which resulted in excellent responses except for the orbital tumors. Two patients were then treated with vemurafenib, which resulted in rapid regression of the orbital lesions. CONCLUSION Pegylated interferon-α was highly effective in the control of cardiac, perirenal, skeletal and cerebral involvement but not the orbital tumors. The infiltrative orbital lesions of Erdheim-Chester disease would appear more responsive to vemurafenib.

Abstract
BACKGROUND Interferon alpha (IFN-α) is a preferred therapy for antiviral treatment of children with chronic hepatitis B (CHB) aged > 1 year currently. Peginterferon alpha-2a (Peg-IFN α-2a) is a recommended international guideline for treatment of CHB children, which is limited to children aged > 3 years. But the exact efficacy and safety of IFN-α and Peg-IFN α-2a for treating CHB are not sufficient. METHODS Clinical manifestations, baseline characteristics, related laboratory tests and adverse events were retrospectively analyzed in children with CHB, who visited Children's Hospital of Fudan University and were treated with IFN α-2b or Peg-IFN α-2a monotherapy and followed up from January 2003 to October 2018. RESULTS A total of 36 immune-active patients without advanced fibrosis were enrolled to be treated with IFN α-2b (group A, n = 18) or Peg-IFN α-2a (group B, n = 18). IFN α-2b or Peg-IFN α-2a was administered for a median of 48 weeks subcutaneously by body surface area (BSA) category at a dose of 3 MU/m2 or 104 μg/m2, respectively. HBV e antigen (HBeAg) seroconversion rates at 48 weeks post-treatment were higher in group A than group B (92.9% vs. 87.5%), so as the rates of HBsAg clearance (22.2% vs. 11.1%), and hepatitis B virus (HBV)-DNA < 1000 IU/mL (88.9% vs. 83.3%). Only mild flu-like symptoms and transient neutropenia appeared in some children at the early stage of treatment. No severe abnormal results was observed in other laboratory assessments. CONCLUSION The antiviral monotherapy of 48-week IFN α-2b or Peg-IFN α-2a in children with CHB is well tolerated and effective, which is associated with higher rates of HBeAg seroconversion and HBsAg clearance than in adults and previously pediatric patients.

Abstract
BACKGROUND: Chronic hepatitis C virus infection represents a more frequent cause of liver cirrhosis and hepatocellular carcinoma. Statins, inhibit HCV replication in vitro, enhance the antiviral effect of the already known antiviral drugs and reduce their resistance. AIM: To determine the impact of additional therapy (treatment with Atorvastatin 20 mg) to the standard antiviral therapy (pegylated interferon alpha-peg-IFN α and ribavirin) on achieving sustained virological response (SVR). MATERIAL AND METHODS: In the study which is comparative, open-label, prospective-retrospective, 70 patients diagnosed with chronic hepatitis C virus infection who met criteria for treatment with standard antiviral therapy combined with anti-lipemic therapy (Atorvastatin 20 mg) were included. Patients in the study were divided into two groups: one group of 35 patients receiving combination therapy (Atorvastatin + peg-IFN α + Ribavirin) and another group of 35 patients received only standard antiviral therapy. Those parameters were followed in all patients: genotyping, quantification of the virus, histological assessment of liver inflammation and fibrosis degree (before starting treatment), the presence of steatosis, laboratory analysis: hematology, liver, lipid and carbohydrate status, insulin blood level (the calculation of HOMA-IR) and body mass index (BMI) calculation. The overall treatment of the patients depends from the virus genotype, thus, patients with genotype 1 and 4 received 48 weeks standard antiviral therapy, but patients with genotypes 2 and 3 received 24 weeks of antiviral therapy. SVR was considered an undetectable level of HCV RNA levels 24 weeks after completion of antiviral therapy. The results were statistically analysed, and all results for p < 0.05 were considered statistically significant. RESULTS: Combination therapy leads to a slightly higher percentage of SVR (85.71%) in patients with chronic hepatitis C versus standard therapy (74.29%), but in a group of patients with genotype 3 this rate of SVR amounting to 95.83%. Combination therapy leads to significant improvement of lipid and glucose status after treatment, and in terms of side effects, there was no appearance of serious adverse events that would be a reason for discontinuation of the therapy. CONCLUSION: Combination therapy Atorvastatin + pegylated interferon alpha + Ribavirin leads to high rate of SVR of 95.83% in patients with chronic hepatitis C, genotype 3. Statins can be used safely in patients with chronic hepatitis C.

Abstract
SUMMARY – The prevalence of chronic hepatitis C increases in elderly patients. The aims of this study were to identify the factors associated with hepatocellular carcinoma (HCC) and end-stage liver disease development and to evaluate the efficacy and safety of pegylated interferon (PEG-IFNα) plus ribavirin (RBV) therapy in elderly patients. A retrospective cohort study included all consecutive patients with hepatitis C virus (HCV) infection treated with PEG-IFNα+RBV between 2003 and 2013. Elderly patients had a higher frequency of poor prognostic factors including genotype 1 infection, high fibrosis, and high fibrosis index based on four factors (FIB-4) score. The sustained virologic response (SVR) rate for genotype 1 was significantly lower (35.8% vs. 57.1%), while the frequency of PEG-IFNα (27.2% vs. 7.8%), RBV dose reduction (19.6% vs. 9.7%) and treatment discontinuation (13.0% vs. 4.1%) was significantly higher in elderly patients. However, age was not associated with SVR in multivariate analysis, and comparable SVR rates were achieved when adjusted for fibrosis score (Ishak ≤3: 66.7% vs. 69.8%). During the follow-up, HCC was diagnosed in 18 elderly patients (3 SVR+, 4 SVR- and 9 untreated patients). In conclusion, selected elderly patients can achieve comparable SVR rates as younger patients, but with a higher rate of side effects. Since complications of HCV infection occur more frequently in elderly patients, they should be given priority for antiviral therapy.

Abstract
Hepatitis B virus (HBV) dynamics in treated patients can be complex and differ considerably from other viral infections. We analyse dynamics of liver and serum levels of HBV DNA in 24 chronically HBV-infected individuals undergoing 1 year of combination therapy with pegylated interferon alpha and adefovir dipivoxil (ADV), followed by 2 years of ADV monotherapy. Serum viral dynamics differentiated the patients into four response groups dependent on how quickly viremia became undetectable: quickly suppressed (HBV DNA <100 copies/ml within 8 weeks and staying suppressed, GRP1); quickly suppressed but some rebound (<10,000 copies/ml, GRP2); slow decay (GRP3); virological failures (>10,000 copies/ml, GRP4). These groups did not differ before start of therapy by serum HBV DNA (p=0.2), HBsAg (p=0.1), ALT (p=0.4), total HBV DNA within the liver (p=0.08), or cccDNA (p=0.3). Despite very different serum HBV DNA levels after 3 years, there was no statistical difference in total HBV DNA within the liver (p=0.08), nor in cccDNA levels (p=0.1), but HBsAg levels in serum were significantly lower for GRP1 compared to GRP4 (p=0.02). Efficacy in terms of reduction over the 3 years of serum HBV DNA, liver HBV DNA, cccDNA, and ratios of liver HBV DNA to cccDNA were 99.98%, 99.5%, 98.4%, and 83.2% respectively, exhibiting larger antiviral effects in serum than in liver. Over the course of therapy, HBV DNA viremia exhibited large oscillations for some individuals. Mathematical modelling reproduced the dynamics of these diverse groups by assuming a number of viral clones arose that experienced delayed recognition by the antibody response. Large viremia oscillations under therapy suggest sequential outgrowth of viral clones with delayed recognition by the humoral response.

Abstract
BACKGROUND Current treatment combinations for chronic hepatitis C virus infection still include pegylated interferon and ribavirin despite the new therapeutic options available. Interferon-based treatments are associated with a high incidence of adverse effects. Central nervous system events are among the most frequent adverse drug reactions and their influence on treatment adherence and effectiveness is controversial. OBJECTIVE The aim of the study was to evaluate neuropsychiatric adverse effects of interferon-based treatment for chronic hepatitis C in standard multidisciplinary clinical practice. Risk factors for these adverse effects and their impact on adherence and sustained viral response were also evaluated. Setting Ambulatory care pharmacy in coordination with the liver unit and the infectious diseases unit at a 650-bed tertiary university hospital. METHODS We included all consecutive patients with chronic hepatitis C who completed treatment with pegylated interferon and ribavirin between 2005 and 2013. All patients underwent a multidisciplinary follow-up during treatment. MAIN OUTCOME MEASURES Neuropsychiatric adverse effects were evaluated in relation to severity, management and outcome. The presence of anxiety and depression was evaluated by means of specific tests. RESULTS A total of 717 treatments in 679 patients were included. During treatment, we detected 1679 neuropsychiatric adverse effects in 618 patients (86.2 %), generating 1737 clinical interventions. Fifty-seven (3.3 %) neuropsychiatric adverse effects were severe and 2 (0.1 %) were life-threatening (suicidal attempts). Most neuropsychiatric adverse effects (1555 events, 92.6 %) resolved without sequelae. Psychiatric medication was required in 289 patients (40.3 %). Sustained viral response was achieved in 400 cases (55.8 %) and was associated with adherence (OR = 1.942, 95 % CI = 1.235-3.052, p = 0.004). A multivariate analysis did not show any relationship between neuropsychiatric adverse effects and treatment adherence or sustained viral response. A psychiatric history was a strong risk factor for depression, anxiety and other psychiatric disorders during treatment. CONCLUSION Neuropsychiatric adverse effects during interferon-based treatments in patients with chronic hepatitis C were common but mostly mild or moderate. Early detection and accurate multidisciplinary management avoided treatment discontinuation, ensuring adherence and attaining sustained viral response. The identified risk factors could be used to determine patients eligible for interferon-free combinations, thus optimizing health system economics.

Abstract
BACKGROUND Treatment of chronic hepatitis C (CHC) with pegylated interferon-alpha/ribavirin is associated with well-characterized dermatological adverse events (AEs), which can lead to premature discontinuation of treatment. OBJECTIVE To investigate the incidence and spectrum of dermatological AEs during CHC treatment with interferon-alpha plus ribavirin and analyzed factors predisposing patients to such reactions. STUDY DESIGN Between January 2008 and December 2012, 152 CHC patients who had received interferon/pegylated interferon plus ribavirin therapy were enrolled in this retrospective study. To determine which factors were associated with dermatological AE development, a Cox proportional-hazards regression analysis was performed. RESULTS Thirty dermatological AEs were recorded in 28 (18.4%) patients. These reactions included 14 (9.2%) patients with eczematous reactions, four (2.6%) patients with xerosis, three (2.0%) patients with new-onset or exacerbation of psoriasis, two (1.3%) patients with lichenoid eruption, two (1.3%) patients with diffuse folliculitis and one patient with lichen planus, alopecia areata, hypermelanosis, and necrosis of the skin and toenails. Application of the Cox proportional-hazards model revealed that age older than 60 years (HR=1.070; 95% CI: 1.043-1.096), pre-existing anaphylaxis/skin disease (HR=2.612; 95% CI: 1.593-3.324), cirrhosis (HR=1.863; 95% CI: 1.047-3.013), and treatment with pegylated interferon formulations (HR=1.930; 95% CI: 1.052-3.687) were associated with occurrence of dermatologic AEs. Twenty-seven (90%) skin conditions were classified as mild to moderate, while one case (3.3%) warranted premature discontinuation of treatment. CONCLUSION Dermatological AEs resulting from interferon-alpha/ribavirin treatment of CHC contribute to a wide spectrum involve the skin, mucous membrane, hair, and nails. These dermatological AEs correlated with older age, previous skin condition, cirrhosis, and use of pegylated interferon formulations.

Abstract
Background/Aims We aimed to evaluate the efficacy and safety of peginterferon plus ribavirin for chronic hepatitis C (CHC) patients under real life setting in Korea. Methods We retrospectively analyzed the medical records of 758 CHC patients treated with peginterferon plus ribavirin between 2000 and 2008 from 14 university hospitals in the Gyeonggi-Incheon area in Korea. Results Hepatitis C virus (HCV) genotype 1 was detected in 61.2% of patients, while genotype 2 was detected in 35.5%. Baseline HCV RNA level was ≥6×105 IU/mL in 51.6% of patients. The sustained virological response (SVR) rate was 59.6% regardless of genotype; 53.6% in genotype 1 and 71.4% in genotype 2/3. On multivariate analysis, male gender (p=0.011), early virological response (p<0.001), genotype 2/3 (p<0.001), HCV RNA <6×105 IU/mL (p=0.005) and adherence to the drug >80% of the planned dose (p<0.001) were associated with SVR. The rate of premature discontinuation was 35.7%. The main reason for withdrawal was intolerance to the drug due to common adverse events or cytopenia (48.2%). Conclusions Our data suggest that the efficacy of peginterferon and ribavirin therapy in Koreans is better in Koreans than in Caucasians for the treatment of CHC, corroborating previous studies that have shown the superior therapeutic efficacy of this regimen in Asians.
