Abstract
Pegylated interferon alpha 2a continues to be used for the treatment of chronic hepatitis D. The reported on-treatment virologic response varies between 17 and 47%, with relapses in more than 50% of these patients. No stopping rules have been defined, and the duration of the treatment is not clearly established, but it should be between 48 and 96 weeks. In total, 76 patients with compensated liver disease treated with peg-interferon according to the Romanian National protocol for the treatment of hepatitis D were retrospectively included. The duration of treatment was up to 96 weeks, with the following stopping rules: less than a 2 log HDV RNA decrease by week 24 and less than a 1 log decrease every 6 months afterwards. Six months after stopping the treatment, it can be restarted for unlimited cycles. The inclusion criteria were aged above 18, HBs Ag-positive, HDV RNA detectable, ALT above ULN and/or liver fibrosis at least F1 at liver biopsy, or Fibrotest and/or Fibroscan higher than 7 KPa and/or inflammation at least A1 at liver biopsy or Fibrotest. We monitored our patients for a total period of 4 years (including those that repeated the cycle). After the first 6 months of treatment, 27 patients (35.5%) had a greater than 2 log HDV RNA decrease, 19 of them achieving undetectable HDV RNA. Seventeen patients (22.3%) had undetectable HDV RNA 24 weeks after stopping 96 weeks of treatment, and none relapsed in the following 2 years. Of these 17 patients, 6 were cirrhotic, and 4 had F3. Undetectable HDV RNA at 24 weeks was the only parameter that predicted a long-term suppression of HDV RNA. In 49 patients, the treatment was stopped after 6 months according to protocol, but it was restarted 6 months later. Five of these patients finished a 48-week course of treatment; none achieved undetectable HDV RNA. During the first course of therapy, 45 patients had at least one moderate adverse reaction to treatment. In one patient, the treatment was stopped due to a serious adverse event (osteomyelitis). Treatment doses had to be reduced in 29 patients. The virologic response at week 24 can select the patients who will benefit from continuing the treatment from those who should be changed to another type of medication when available.

Abstract
The long-term impact, incidence and risk factors of thyroid dysfunction in chronic hepatitis B (CHB) patients receiving pegylated interferon (IFN) alpha (PegIFN-alpha) therapy remain unclear. We aim to investigate the long-term safety of thyroid dysfunction in CHB patients receiving PegIFN-alpha. A retrospective observational study of 425 CHB patients with normal baseline thyroid function was carried out. Patients were followed up over 10 years to assess thyroid function after receiving IFN. At the end of the IFN therapy, 67 patients (15.8%) had developed thyroid dysfunction, 31 patients (46.3%) had hyperthyroidism and 64.4% presented with subclinical thyroid dysfunction. In follow-up of thyroid dysfunction patients, 37 patients (74.0%) spontaneously regained normal thyroid function. Pretreatment thyroid-stimulating hormone (TSH) level, thyroid peroxidase antibody (TPOAb) positivity and free thyroxine (FT4) were independent risk factors associated with thyroid dysfunction incidence. High TSH level (OR = 9.866, 95%CI, 3.245-29.998) was associated with a greater likelihood of hypothyroidism. High FT4 levels (OR = 0.464, 95%CI, 0.248-0.868) indicate a low likelihood of thyroid dysfunction. Thyroid dysfunction is a common but acceptable side effect of IFN therapy for CHB. Most thyroid dysfunction is reversible. Pretreatment TSH level and TPOAb positivity are risk factors for thyroid dysfunction development during IFN therapy. A high TSH level predicts an increased incidence of hypothyroidism. Moreover, FT4 may be a protective factor for thyroid dysfunction.

Abstract
Co-infection of Hepatitis B (HBV) and Delta viruses (HDV) represent the most severe form of viral hepatitis. While treatment with pegylated Interferon alpha (PEG-IFNα) is well established, therapy with nucleoside or nucleotide analogues (NA) has been a matter of debate. We aimed to investigate the role of NA treatment in a well-defined single centre cohort.In a retrospective approach, we observed 53 HDV RNA positive and/or anti-HDV-positive patients recruited at a German referral centre between 2000 and 2019. Patients were followed for at least 3 months (mean time of follow up: 4.6 years; range: 0.2-14.1 years). Patients who had liver transplantation or hepatocellular carcinoma at the time of presentation were excluded. 43% (n = 23) were treated with NA, 43% (n = 23) received IFNα-based therapies and 13% (n = 7) were untreated.Liver cirrhosis was already present in 53% (28/53) of patients at first presentation. During follow-up, liver-related endpoints developed in 44% of all patients (n = 23). NA-treatment was associated with a significantly worse clinical outcome (P = .01; odds ratio [OR] = 4.92; CI = 1.51-16.01) compared to both, untreated (P = .38; OR = 0.46; CI = 0.80-2.61) and IFNα-based-treated patients (P = .04; OR = 0.29; CI = 0.89-0.94) in univariate logistic regression analysis. HBsAg levels declined by more than 50% during NA-based therapy in only 7 cases (7/23; mean time: 3.6 years; range: 0.8-8.5 years) and during IFNα-based therapy in 14 cases (14/23; mean time: 2.8 years, range 0.7-8.5 years). HDV RNA became undetectable during follow up in 30% of patients receiving NA alone (7/23; mean time: 5.0 years; range: 0.6-13.5 years), in 35% of patients receiving IFNα-based therapy (8/23; mean time: 2.9 years, range: 0.3-7.6 years).The effect of NA in patients with HBV/HDV co-infection is limited. Treatment with NA was associated with a higher likelihood of clinical disease progression. Interferon alpha therapy was beneficial in reducing liver complications and improves long-term outcome.

Abstract
The main reason for the ineffectiveness of antiviral therapy in patients with chronic hepatitis C that impedes full and adequate treatment of IFN-α and ribavirin is the development of neutropenia and thrombocytopenia. The present study included 63 patients (59% men and 41% women) with chronic hepatitis C that did not previously receive antiviral therapy. All patients had HCV genotype-1 (15 patients with genotype 1a; 42 people, with genotype 1b; 6 patients, with genotypes (1a + 1b)). The patients' age was 33.8 ± 0.7 years, with term of infection 6,1 ± 0,8 years. It was shown that in the case of treatment with Peg-IFN-alpha in combination with ribavirin, a significant decrease in the number of white blood cells, neutrophils and platelets prevailed in patients with HCV-monoinfected genotype 1b in the F0-F2 stages (2,8-8,6 kPa) at METAVIR. With the development of moderate "early" (less than 12 weeks of antiviral therapy) and for the prevention of "late" (more than 12 weeks of treatment) neutropenia, appointment of immune medicine likopid (glucosaminylmuramyldipeptide) at a dosage of 1 mg, 2 times a day for 20 days, in patients with chronic hepatitis C (genotype 1b ) with <F3 fibrosis significantly stimulates leucopoiesis and increases the number of neutrophils and platelets, which makes it possible to avoid reduction of the dose of interferon and to increase the efficiency of the antiviral therapy. Thus, for the first time experimental evidence is presented for the effectiveness of medicinal likopid correction of neutropenia and thrombocytopenia in patients with chronic hepatitis C (genotype 1), which indicates the feasibility of introducing likopid into the antiviral therapy.

Abstract
INTRODUCTION Thyroid dysfunctions (TDs) are associated with pegylated interferon and ribavirin (PegIFN-α/RBV) therapy in patients with chronic hepatitis C (CHC) and are considered as possible extrahepatic manifestation of HCV infection OBJECTIVES This study aimed to assess the long-term outcomes of TDs in patients with CHC treated with PegIFN-α/RBV METHODS A total of 1,047 treatment-naïve patients with CHC were treated with PegIFN-α/RBV. TSH and FT4 were assessed at baseline, every 3 months during therapy and 6, 12 and 24 months after the end of therapy. Analysis was performed for two groups of patients depending on the absence (group A, n=77) or presence (group B, n=39) of TDs at baseline RESULTS At baseline, TDs’ prevalence was 3.7%; 53.8% hypothyroidism, 38.5% goiters, and 7.7% hyperthyroidism. 77 (7.4%) out of 1,008 euthyroid patients developed TDs; 45.5% hypothyroidism, 33.8% hyperthyroidism, 19.5% destructive thyroiditis, and 1.3% goiters. TDs’ remission (TDR) was achieved in 59/116 (50.9%) of treated patients; 64.9% in group A and 23.1% in group B (p<0.001). Hyperthyroidism as compared to hypothyroidism increases the odds of TDR (OR=4.87 (1.65-14.35), p=0.004), whereas preexisting TDs and higher baseline viral load tend to decrease the probability of TDR (OR=0.21 (0.07-0.58), p=0.003 and OR=0.4 (0.22-0.73), p=0.003, respectively) CONCLUSIONS The prevalence of TDs was low but over one-third of patients in whom TDs developed under PegIFN-α/RBV therapy did not recover. In one-fourth of patients with preexisting TDs remissions were observed. Treatment with PegIFN-α in the past must be taken into account as a potential cause of TDs

Abstract
Under-recognition and under-treatment of chronic hepatitis C virus (HCV) infection is an important determinant of the disease outcome. The aim of this study was to investigate the treatment rate and factor of initiation of interferon-based antiviral treatment for chronic hepatitis C patients in a prospective, multicenter Korean HCV cohort. Treatment-naïve 759 patients with chronic HCV infection were prospectively followed from January 2007-2013 at six university hospitals during a median (interquartile range) follow-up of 769 (76-1,427) days. The subjects consisted of patients with chronic hepatitis C (n = 553, 72.9%), liver cirrhosis (n = 127, 16.7%), and hepatocellular carcinoma (n = 79, 10.4%), and were treated usually using pegylated interferon alpha and ribavirin. Treatment initiation rate and its related factors were analysed. The initiation rate of antiviral treatment was 37.3% (n = 273), and the cumulative probability of treatment initiation over 5 years was 39.4%. Multivariate analysis showed that age <58 years (hazard ratio [HR] = 1.588, 95% CI = 1.151-2.193), job employment (HR = 1.737, 95% CI = 1.279-2.363), absence of HCC (chronic hepatitis, HR = 2.534, 95% CI = 1.003-6.400; liver cirrhosis, HR = 2.873, 95% CI = 1.101-7.494), alanine transaminase (ALT) >40 IU/L (HR = 1.682, 95% CI = 1.228-2.303), and genotype 2 (HR = 1.364, 95% CI = 1.034-1.798) were independent factors related to treatment initiation. Interferon-based antiviral treatment was initiated in more than one third of chronic HCV infected patients visiting university hospitals, who were young, employed, HCV genotype 2, and with abnormal ALT without HCC, in Korea.

Abstract
The standard of care (SOC) for the treatment of HCV genotype 2 (HCV-2) was pegylated interferon alpha plus ribavirin (PEG-IFN/RBV) at weight-based doses for a response-guided duration. The launches of sofosbuvir and daclatasvir in 2014 have resulted in new, better tolerated and shorter treatment. The combination of sofosbuvir and RBV for 12 weeks appears to be the new SOC in both European and American guidelines. The cost and therefore the access to this treatment remains a problem in many countries because of major economic constraints. For the few more difficult-to-treat patients, a combination of direct acting antivirals may be suitable and is being studied in ongoing trials. Because of rapidly changing treatment recommendations, the decision to treat HCV-2 patients with currently approved drugs or to wait until a better option is available in the future, must be made according to the stage of fibrosis.

Abstract
Treating chronic hepatitis C with pegylated interferon alpha may induce or exacerbate psychiatric illness including depression, mania and aggressive behaviour. There is limited data regarding treatment in the context of chronic schizophrenia. We sought to establish the safety and efficacy of treating patients with schizophrenia. Patient and treatment data, prospectively collected on the Scottish hepatitis C database, were analysed according to the presence or absence of a diagnosis of schizophrenia. Time from referral to treatment, and the proportion of patients commencing treatment in each group, was calculated. Outcomes including sustained viral response rates, reasons for treatment termination and adverse events were compared. Of 5497 patients, 64 (1.2%) had a diagnosis of schizophrenia. Patients with schizophrenia (PWS) were as likely to receive treatment as those without [28/61(46%) vs 1639/4415 (37%) P = 0.19]. Sustained viral response (SVR) rates were higher in PWS [21/25 (84%) vs 788/1453 (54%) P < 0.01]. SVR rates by genotype were similar [4/8 (50%) vs 239/684 (35%) Genotype 1 (P = 0.56), 17/17 (100%) vs 599/742 (81%) non-Genotype 1 (P = 0.09)]. Adverse events leading to cessation of treatment were comparable [2/25(8%) vs 189/1453 (13%) P: 0.66]. Patients with schizophrenia are good candidates for hepatitis C treatment, with equivalent SVR and treatment discontinuation rates to patients without schizophrenia.

Abstract
The incidence of retinopathy in patients with chronic hepatitis C treated with interferon-based regimens has been variably reported in the literature. There is no consensus regarding ophthalmologic screening before and during treatment with interferon-based therapy. To assess the incidence of retinopathy in patients with chronic hepatitis C being treated with interferon-based regimens and estimate the rate of resolution. A systematic literature search was performed to locate all relevant publications. Pooled incidence of retinopathy was calculated in patients treated with interferon or pegylated interferon. We also estimated the rate of discontinuation of treatment and resolution after the treatment was stopped. A total of 21 studies fulfilled the inclusion criteria. The overall incidence of retinopathy using random effect model was 27.7% (95% confidence interval [CI] 20.9-34.5%). The pooled incidence of retinopathy in 10 studies that only used pegylated interferon was 20.9% (95% CI: 11.6-29.8). The incidence of retinopathy with pegylated interferon in diabetic and hypertensive patients (high-risk group) was 65.32% and 50.7%, respectively. This was significantly higher compared with the incidence of retinopathy (11.7%) in patients without these risk factors. Overall pooled estimate for the resolution of retinopathy was 87% (95% CI 75.7-98.4%). The rate of discontinuation of treatment was 6.3%. The incidence of retinopathy with pegylated interferon in patients without hypertension and diabetes is low, but the risk is higher in patients with diabetes and hypertension. Routine pretreatment fundoscopic screening may not be warranted in all patients and can be limited to the patients with these risk factors.

Abstract
The treatment of hepatitis C has dramatically improved over the past decade. Unlike any other chronic viral infection, a significant proportion of patients with chronic hepatitis C can be cured. However, the current standard therapy--pegylated interferon alpha and ribavirin--has its limitations. Limited efficacy in patients with hepatitis C virus (HCV) genotype 1 and the side effect profile will necessitate the development of new therapeutic approaches. This review describes the efficacy and optimisation of the current standard therapy of hepatitis C and its problems in special patient populations. New treatment directions beyond interferon alpha based therapies are on the horizon.
