The Relationship

Introduction: Direct-acting antiviral drugs have been recently introduced for management of chronic hepatitis C virus (HCV) patients. Those medications have achieved a dramatic improvement of sustained virologic response (SVR) reaching almost 90%. However, reports regarding the increased risk of occurrence or recurrence of hepatocellular carcinoma (HCC) in chronic HCV patients who achieved SVR after direct-acting antiviral drugs are controversial.Methods: We report two cases of giant HCCs complicating chronic HCV infection after direct-acting antiviral drugs-based therapies and were managed by major hepatic resection.Results: Two male patients with chronic HCV infection received several regimens oral direct acting antiviral drugs with a SVR for 3 and 6 months, respectively. They complained of progressive right hypochondrial pain and abdominal enlargement. Two large HCCs were diagnosed (16.2 cm * 17.6 cm * 16.9 cm, and 18 cm * 13 cm * 16.5 cm in dimensions) with markedly elevated serum alpha feto-protein (36,000 and 7,000 ng/ml, respectively). Due to the presence of adequate residual liver volume, the decision was to proceed for surgical resection. Central hepatectomy and extended right hemi-hepatectomy were performed, respectively. Patients had smooth postoperative course and were discharged after 10 and 9 days, respectively.Conclusion: The relationship between direct-acting antiviral drugs and HCC is controversial. Those cases add support to the accumulating literature suggesting the relationship of HCC development in chronic HCV patients receiving direct-acting antiviral drugs. Further prospective studies with adequate long term follow up are needed to prove or disprove this relationship.

Direct-acting antiviral agents (DAAs) that allow for rapid clearance of hepatitis C virus (HCV) may evoke immunological changes. Some cases of rapid de novo hepatocellular carcinoma (HCC) development or early recurrence of HCC after DAA treatment have been reported. During chronic HCV infection, natural killer (NK) cells exhibited a deviant functional phenotype with decreased production of antiviral cytokines and increased cytotoxicity; however, DAA treatment rapidly decreased their cytotoxic function. Effective DAA therapy also suppressed the intrahepatic activation of macrophages/monocytes. This was followed by a decrease in mucosal-associated invariant T (MAIT) cell cytotoxicity without normalization of cytokine production. Rapid changes in the phenotypes of NK and MAIT cells after DAA treatment may attenuate the cytotoxicity of these cells against cancer cells. Moreover, DAA treatment did not normalize the increased frequencies of regulatory T cells even after clearance of HCV infection. Thus, the persistently increased frequency of regulatory T cells may contribute to a local immunosuppressive milieu and hamper the clearance of cancer cells. This review will focus on recent studies describing the changes in innate and adaptive immune responses after DAA treatment in patients with chronic HCV infection in the context of de novo occurrence or recurrence of HCC.

Background and AimsChronic hepatitis C virus (HCV) infection is associated with dysregulation of glucose homeostasis, including insulin resistance (IR) and type 2 diabetes. However, independent risk factors associated with IR in chronic HCV-infected patients have not been detailly elucidated. Previous data regarding the impact of HCV elimination by direct-acting antiviral agents (DAAs) on glucose homeostasis is insufficient and controversial. This study aimed to analyze the independent factors associated with IR and to evaluate the changes in glucose homeostasis in chronic HCV-infected patients treated with DAAs therapies.MethodsWe screened 704 patients with chronic HCV infection who underwent treatment with interferon-free DAAs. Patients’ baseline characteristics, biochemical and virological data were collected. The outcome measurements were their IR and β-cell function assessed by the homeostasis model assessment (HOMA) method at baseline and 12-weeks post-treatment.ResultsHigh IR (HOMA-IR ≥ 2.5) was observed in 35.1% of the patients. Multivariable logistic regression analysis revealed that body mass index (BMI) >25 kg/m2, treatment experience, elevated baseline levels of alanine aminotransferase (ALT) and triglyceride, as well as Fibrosis-4 score >3.25 were independently associated with high IR. In patients who achieved sustained virological response (SVR), no significant change in mean HOMA-IR was observed from baseline to 12-weeks post-treatment (2.74 ± 2.78 to 2.54 ± 2.20, p = 0.128). We observed a significant improvement in β-cell secretion stress from 121.0 ± 110.1 to 107.6 ± 93.0 (p = 0.015). Subgroup analysis revealed that SVR was associated with a significant reduction in mean HOMA-IR in patients with baseline HOMA-IR ≥ 2.5 (5.31 ± 3.39 to 3.68 ± 2.57, p < 0.001), HCV genotype 1 (3.05 ± 3.11 to 2.62 ± 2.05, p = 0.027), and treatment experience (4.00 ± 3.37 to 3.01 ± 2.49, p = 0.039).ConclusionsThere were several independent factors associated with IR in patients with chronic HCV infection, including obesity, treatment experience, high serum ALT and triglyceride levels, as well as advanced hepatic fibrosis. After viral elimination by DAAs, we observed a significant reduction in mean HOMA-IR in patients with baseline high IR, HCV genotype 1, and treatment experience.
