Evolution of ferritin levels in hepatitis C patients treated with antivirals. Sci Rep 2020; 10:19744. [PMID: 33184464 PMCID: PMC7661708 DOI: 10.1038/s41598-020-76871-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Accepted: 11/02/2020] [Indexed: 12/11/2022] Open
Abstract
The evolution of ferritin levels in hepatitis C virus (HCV)-infected patients with sustained virological responses (SVRs) following various therapy regimens remains elusive. An 8-year prospective cohort study of 1194 HCV-infected patients [interferon-based therapy (n = 620), direct-acting antiviral agent (DAA) therapy (n = 355)] was conducted. At baseline, sex, alanine aminotransferase (ALT), triglycerides, homeostatic model assessment of insulin resistance (HOMA-IR), estimated glomerular filtration rate (eGFR), hemoglobin, iron/total iron-binding capacity (Fe/TIBC) and IFNL3-rs12979860 genotypes were associated with ferritin levels. At 24 weeks posttherapy, ALT, triglycerides, total cholesterol, eGFR, Fe/TIBC and the therapy regimen were associated with ferritin levels in SVR patients. Among interferon-treated patients, ferritin levels increased at 24 weeks posttherapy, regardless of SVR, and 24-week posttherapy ferritin levels were higher in non-SVR patients (n = 111) than in SVR patients (n = 509); ferritin levels began decreasing at 3 years posttherapy and were lower than pretherapy levels since 4 years posttherapy in SVR patients. Among DAA-treated SVR patients (n = 350), ferritin levels decreased and remained stable since 24 weeks posttherapy. ALT, triglycerides, eGFR, and Fe/TIBC were HCV-unrelated factors associated with ferritin levels; sex, HOMA-IR, total cholesterol, hemoglobin and IFNL3-rs12979860 genotype were HCV-related factors associated with ferritin levels. In interferon-treated SVR patients, the increased trend of posttherapy ferritin levels was not reversed until 4 years posttherapy. In DAA-treated SVR patients, ferritin levels decreased since 24 weeks posttherapy.

Verification of B-lymphocyte activating factor's involvement in the exacerbation of insulin resistance as well as an autoimmune response in patients with nonalcoholic steatohepatitis and patients with HCV-related chronic liver disease. Diabetol Metab Syndr 2017; 9:45. [PMID: 28630652 PMCID: PMC5470186 DOI: 10.1186/s13098-017-0243-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2017] [Accepted: 05/30/2017] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Ten to forty percent of nonalcoholic steatohepatitis (NASH) and HCV-related chronic liver disease (CLD-C) patients have antinuclear antibodies (ANAs). However, the relationship between autoimmune response and insulin resistance remains uncertain among those patients. The primary purpose of this study was to investigate whether or not ANA status was associated with the development of insulin resistance and obesity in NASH and CLD-C patients. METHODS Degrees of hepatic fibrosis and steatosis were evaluated by the classification proposed by Brunt et al. Obesity and insulin resistance were estimated by calculating body mass index and the value of homeostasis model of for assessment of insulin resistance (HOMA-IR), respectively. A revised scoring system was applied to the diagnosis of autoimmune hepatitis (AIH). Serum B-lymphocyte activating factor (BAFF) levels were determined, using an ELISA technique. RESULTS Ten of 25 (40%) NASH patients and 9 of 22 (41%) CLD-C patients had ANAs, though the titers were weak in most patients. Only one NASH patient met the category of "definite" AIH among the enrolled patients. Serum IgG levels were significantly higher in NASH and CLD-C patients with ANAs than in those without ANAs, and NASH and CLD-C patients with ANAs had significantly higher HOMA-IR values than those without ANAs (6.81 ± 3.36 vs. 4.00 ± 2.57, p = 0.0305, 3.01 ± 1.31 vs. 1.28 ± 0.50, p = 0.0011). CLD-C patients with ANAs had more advanced hepatic fibrosis and steatosis than those without ANAs, while ANA status was not associated with hepatic fibrosis or steatosis in NASH patients. Obesity was independent of ANA status in both subjects. Serum BAFF levels were significantly higher in CLD-C patients with ANAs than those in CLD-C patients without ANAs (1303 ± 268 vs. 714 ± 143 pg/ml, p = 0.0036). A close correlation between serum BAFF level and the HOMA-IR value was observed in CLD-C patients (r = 0.467, p = 0.0485). CONCLUSION Our data suggest that NASH and CLD-C patients with ANAs have more severe insulin resistance than those without ANAs. More advanced insulin resistance deriving from excessive BAFF production may result in severe hepatic fibrosis and steatosis in CLD-C patients with ANAs.

Decrease in regulatory T-cell function in chronic hepatitis C patients receiving pegylated-interferon plus ribavirin. Int J Infect Dis 2017; 58:8-17. [PMID: 28238888 DOI: 10.1016/j.ijid.2017.02.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2016] [Revised: 02/17/2017] [Accepted: 02/18/2017] [Indexed: 01/17/2023] Open
Abstract
OBJECTIVES Regulatory T-cells (Tregs) play an important role in the pathogenesis of chronic hepatitis C (CHC) infection. Pegylated interferon is the standard therapy for CHC patients in Asian countries. This study aimed to evaluate the frequency and function of Tregs in CHC patients receiving combination therapy. METHODS CHC patients (n=30) who had elevated alanine aminotransferase and underwent combination therapy were included. Clinical data and Treg function were checked at baseline, 12 weeks after treatment, at the end of treatment, and at the end of 24 weeks of follow-up. Treg immunosuppressive activity was measured as the inhibition ratio of conventional T-cell proliferation. RESULTS Treg-mediated immunosuppression was significantly lower during therapy than at baseline (baseline 44.45%; 12 weeks 18.41% (p=0.042); end of treatment 22.62% (p=0.036); end of follow-up 17.46% (p=0.003)). Treg-mediated immunosuppression was higher in patients with a sustained virological response (SVR) than in those without SVR at the end of follow-up (SVR 24.20%, non-SVR 6.87%; p=0.030). CONCLUSION Treg-mediated immunosuppression was lower during and after combination therapy, regardless of the treatment response, and higher in patients with SVR than in those without SVR at the end of follow-up.

Peginterferon alfa-2a is associated with elevations in alanine aminotransferase at the end of treatment in chronic hepatitis C patients with sustained virologic response. PLoS One 2014; 9:e100207. [PMID: 24937007 PMCID: PMC4061072 DOI: 10.1371/journal.pone.0100207] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2014] [Accepted: 05/23/2014] [Indexed: 01/08/2023] Open
Abstract
Background The purpose of this study was to investigate the incidence and demographic/clinical factors of alanine aminotransferase (ALT) abnormalities at the end of treatment (EOT) in chronic hepatitis C (CHC) patients with sustained virologic response (SVR). Methods and Findings Seven hundred naïve CHC patients who underwent combination treatment between January 2003 and December 2010 were included in the study. The patients with SVR and serum ALT>upper limit of normal (ULN) at the EOT were further analyzed. The effects of clinical characteristics, treatment regimen, and virologic variables were evaluated by logistic regression. Of the 700 included patients, 488 (69.7%) achieved an SVR after treatment, and 235 (33.6%) had serum ALT levels>ULN at the EOT. Of those 488 patients, 137 (28.1%) had abnormal ALT values at the EOT. A multivariate analysis showed that the occurrence of ALT abnormalities at the EOT was significantly associated with pegylated interferon (PEG-IFN) alfa-2a (odds ratio [OR], 2.24; 95% confidence interval [CI], 1.45–3.45; P<0.001), baseline fatty liver (OR, 1.76; 95% CI, 1.16–2.76; P = 0.007), and baseline liver cirrhosis (OR, 2.35; 95% CI, 1.35–4.09; P = 0.002). Conclusions Use of PEG-IFN-alfa-2a, fatty liver, and cirrhosis are important factors associated with EOT-ALT abnormality in CHC patients receiving combination therapy that achieve an SVR. PEG-IFN-alfa-2a-related EOT-ALT elevation will become normal at the end of follow-up, but fatty liver and cirrhosis-related ALT elevation will not be resolved.

Hepatitis C Virus Clearance after Discontinuation of Pegylated Interferon Alpha-2a Monotherapy in a Child. Case Rep Med 2012; 2012:597348. [PMID: 23118765 PMCID: PMC3483865 DOI: 10.1155/2012/597348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2012] [Accepted: 09/27/2012] [Indexed: 12/03/2022] Open
Abstract
The present patient was a 4-year-old boy. His hepatitis C virus genotype was 2a, and his viral load was high (1400,000 U/mL). The pretreatment liver biopsy revealed no fibrosis or malignancy and mild chronic hepatitis; his Knodell's histological activity (HAI) score was 4. Single nucleotide polymorphism of IL28B (rs8099917) was major type. The patient began antiviral treatment with pegylated interferon alpha 2a (90 μg/week). At week 9, serum HCV RNA became undetectable, with a sensitivity of 50 copies/mL. Antiviral treatment was discontinued at week 11 because the ALT level increased to 610 U/L. After discontinuation of therapy, the patient's serum HCV RNA status became positive again. The serum viral load increased to 100,000 U/mL. During this period, he had been observed without medication. Sixteen months after stopping treatment, serum HCV became undetectable. Over a 4-year period, HCV RNA became negative and his anti-HCV antibody titer gradually decreased. In conclusion, though antiviral therapy resulted in failure or incomplete therapy, a reduced viral load resulted in viral clearance in the present patient. Interleukin 28B genotype might have association with the clearance of hepatitis C virus after discontinuation of antiviral therapy.

Abstract
An increase in serum ferritin levels during combined interferon-ribavirin treatment in chronic patients infected with hepatitis C virus (HCV) can occur. A study was conducted to determine whether observing the kinetics of serum ferritin levels during antiviral therapy, may assist in predicting the rate of sustained virological response. The kinetics of serum ferritin levels during antiviral therapy in treatment-naive, adherent patients with chronic HCV who had early virological response were characterized. Thirteen patients achieved sustained virological response (group 1) while eight patients did not (group 2). Pre-treatment serum ferritin levels were higher in group 2 patients. During antiviral therapy, serum ferritin levels increased in both groups. On treatment, the median increase (compared to baseline) and the calculated rate of the increase in serum ferritin levels was higher in group 1 patients (874% vs. 272%, P < 0.05, 63%/week vs. 13%/week, P = 0.024, respectively). Red blood cell lysis did not contribute to the increase in serum ferritin level. Post-treatment (1st month) serum ferritin levels in group 1 patients were lower than in group 2 patients. In addition, the degree of decline in the 1st month serum ferritin levels (from peak levels) in group 1 patients was higher (76% vs. 49%, P = 0.039). Measuring serum ferritin levels during antiviral therapy in HCV patients who had an early virological response may assist in predicting sustained virological response.

Abstract
AIM Elevation of alanine aminotransferase (ALT) levels during pegylated-interferon (peg-IFN) plus ribavirin therapy in patients with chronic hepatitis C [CHC] is a problem that cannot be disregarded. The aim of this study is to assess the frequency and to characterize clinical parameters of this phenomenon. METHODS Two hundred and thirty-five (235) CHC patients with genotype 1b receiving peg-IFN α-2b plus ribavirin therapy were analyzed. Clinical parameters that may be associated with abnormal ALT values during treatment and therapy outcomes were evaluated statistically. One hundred and sixteen (116) patients treated with peg-IFN α-2a plus ribavirin were also included for partial analysis. RESULTS Abnormal ALT values during treatment were observed in 23.0% of patients. It was observed in 14.5% of those with sustained virological response (SVR) and 17.8% of those with relapse, in whom viral clearance was observed during therapy. Multivariate logistic regression analysis revealed that pretreatment ALT values, therapy outcome, and body mass index (BMI) were significant factors related to abnormal ALT values during treatment. Abnormal ALT values during treatment became normal in SVR patients at 6 months after the completion of treatment, but not in NR (non-response) patients. Mean ALT values were significantly higher at some time points during treatment in patients treated with α-2a when compared to those treated with α-2b. CONCLUSION Abnormal ALT values during peg-IFN plus ribavirin treatment are observed relatively frequently, even in patients without detectable HCV RNA. Direct or indirect involvement of drugs is considered as one possible cause.

Abstract
UNLABELLED The incidence and clinical meaning of elevated alanine aminotransferase (ALT) in chronic hepatitis C patients who are hepatitis C virus (HCV)-RNA negative during pegylated interferon (PEG-IFN) and ribavirin therapy have not been completely characterized. In this study our aim was to assess the incidence, pattern, predictive factors, and clinical meaning of elevated ALT in a cohort of 173 chronic hepatitis C patients who obtained viral clearance during either PEG-IFNalpha2(a) or alpha2(b) and weight-based ribavirin therapy. Patients were defined sustained viral responders (SVRs) or relapser responders (RRs) on the basis of a serum HCV-RNA result at 24-week follow-up. SVR and RR were obtained in 141 (58%) and 32 patients (13%), respectively. Among the 173 study patients, 57 patients (33%) had undetectable serum HCV-RNA and elevated ALT in at least one evaluation (weeks 2, 4, 12, 24 in all genotypes, and week 48 in HCV genotype 1 and 4 alone), and this phenomenon was not differently distributed between SVRs and RRs. No pretreatment demographic (age, gender), clinical (ALT levels, histological grade and stage, body mass index) and viral (load, genotype) parameter was associated with this phenomenon. The incidence of elevated ALT levels was not associated with type of PEG-IFN and ribavirin dose. Elevated ALT levels showed a different longitudinal pattern, occurring more frequently between week 12 and the end of treatment in RR as compared to SVR patients (90% versus 9%, P = 0.000001). CONCLUSION The occurrence of elevated ALT levels in HCV-RNA-negative patients during PEG-IFN and ribavirin therapy is a fairly frequent and unpredictable phenomenon. Although ALT elevation per se is not associated with a greater risk of relapse, its occurrence in the later phases of therapy is more common in relapsing patients.
