Background & Aims: Until recently, pegylated interferon-alfa-2a (PEG-IFNa) therapy was the only treatment option for patients infected with hepatitis D virus (HDV). Treatment with PEG-IFNa with or without tenofovir disoproxil fumarate (TDF) for 96 weeks resulted in HDV RNA suppression in 44% of patients at the end of therapy but did not prevent short-term relapses within 24 weeks. The virological and clinical long-term effects after prolonged PEG-IFNa-based treatment of hepatitis D are unknown., Methods: In the HIDIT-II study patients (including 40% with liver cirrhosis) received 180 μg PEG-IFNa weekly plus 300 mg TDF once daily (n = 59) or 180 μg PEG-IFNa weekly plus placebo (n = 61) for 96 weeks. Patients were followed until week 356 (5 years after end of therapy)., Results: Until the end of follow-up, 16 (13%) patients developed liver-related complications (PEG-IFNa + TDF, n = 5 vs PEG-IFNa + placebo, n = 11; p = .179). Achieving HDV suppression at week 96 was associated with decreased long-term risk for the development of hepatocellular carcinoma (p = .04) and hepatic decompensation (p = .009). Including complications irrespective of PEG-IFNa retreatment status, the number of patients developing serious complications was similar with (3/18) and without retreatment with PEG-IFNa (16/102, p > .999) but was associated with a higher chance of HDV-RNA suppression (p = .024, odds ratio 3.9 [1.3-12])., Conclusions: Liver-related clinical events were infrequent and occurred less frequently in patients with virological responses to PEG-IFNa treatment. PEG-IFNa treatment should be recommended to HDV-infected patients until alternative therapies become available. Retreatment with PEG-IFNa should be considered for patients with inadequate response to the first course of treatment., Clinical Trial Registration: NCT00932971., (© 2023 The Authors.

Background & Aims: Infection with the hepatitis D virus (HDV) causes the most severe form of viral hepatitis with a high risk to develop clinical complications of liver disease. In addition, hepatitis delta has been shown to be associated with worse patient-reported outcomes. Until recently, only pegylated interferon alfa could be used to treat hepatitis delta., Methods: Here, we investigated quality of life (QOL) as assessed by the Short Form 36 Health Survey (SF-36) in patients undergoing antiviral therapy with pegylated interferon alfa (PEG-IFNa-2a)-based treatment in the HIDIT-II trial. HIDIT-II was a randomized prospective trial exploring PEG-IFNa-2a with tenofovir disoproxil (TDF) or placebo for 96 weeks in patients with compensated hepatitis delta. Surveys completed by 83 study participants before, during, and after treatments were available., Results: Overall, we observed a reduced QOL of HDV patients compared with a reference population, both in physical as well as mental scores. Interestingly, PEG-IFNa-2a treatment showed only minor impairment of the QOL during therapy. Moreover, HDV-RNA clearance was not associated with relevant changes in physical or social SF-36 scores, whereas an improvement of fibrosis during treatment was associated with increased QOL. Overall, slight improvements of the QOL scores were observed 24 weeks after the end of treatment as compared with baseline. TDF co-treatment had no influence on QOL., Conclusions: Overall, our findings suggest that PEG-IFNa-2a was reasonably tolerated even over a period of 96 weeks by hepatitis D patients reporting SF-36 questionnaires. Of note, several patients may benefit from PEG-IFNa-2a-based therapies with off-treatment improvements in quality of life., (© 2023 The Authors.

The role of low levels of HDV-RNA during and after interferon therapy of hepatitis D is unknown. We re-analysed HDV RNA in 372 samples collected in the HIDIT-2 trial (Wedemeyer et al, Lancet Infectious Diseases 2019) with the Robogene assay (RA; Jena Analytics). Data were compared with the previously reported in-house assay (IA). We detected HDV-RNA in one-third of samples previously classified as undetectable using the highly sensitive RA. Low HDV viraemia detectable at week 48 or week 96 was associated with a high risk for post-treatment relapse, defined as HDV RNA positivity in both assays at week 120. HDV RNA relapses occurred in 10/15 (67%) patients with detectable low HDV RNA at week 48 and in 10/13 (77%) patients with low viraemia samples at week 96. In contrast, the post-treatment relapse rate was lower in patients with undetectable HDV RNA in both assays during treatment., (© 2020 The Authors.

Background & Aims: Sleep disorders (SDs) are common in cirrhotics and are often associated with hepatic encephalopathy. SDs negatively affect patients' daily activities and work efficiency. For this reason, early diagnosis is important. The methods used for diagnosis of SDs are not practical and need longer periods of application and evaluation. In this study, we aimed to investigate sleep disorders and related clinical parameters in cirrhosis and also wanted to investigate the using of Sleep Timing and Sleep Quality Screening questionnaire (STSQS), a simple form with a short application time, for diagnosis of SDs and its correlation with Pittsburg Sleep Quality Index (PSQI) form., Methods: Cirrhotic patients and age-matched healthy volunteers were enrolled. Patients were excluded from this study if they had neuropsychiatric disease or used excessive alcohol or drugs known to affect sleep. Both groups completed validated Turkish form of PSQI and STSQS. SD was defined as PSQI score (0-21) of >5 or STSQS ≥5., Results: One hundred and thirty-one cirrhotic patients and 18 healthy volunteers were enrolled. SDs in cirrhotics and control group were detected 56.5% and 27.8% by PSQI, 49.6% and 16.7% by STSQS respectively. SDs are the most frequent in the Child C patients, and the least frequent in the Child A patients (P > 0.05). No correlation was found between the MELD score and SDs. SDs were more common in cirrhotic patients with hypoalbuminaemia and low haemoglobin levels. In addition, the patients with decompensated cirrhosis had more frequently SDs than the patients with compensated cirrhosis. In the patient group, sleep latency and total sleep time, sleep parameters were correlated with SDs. STSQS had statistical significant correlation with PSQI for diagnosis of SDs., Conclusion: SDs are common in cirrhotics and STSQS could be an appropriate and practical method for diagnosis of SDS in these patients. We can use it in cirrhotic patients at outpatient clinics., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: The effect of pegylated interferon or its combination with lamivudine on liver histology of patients with chronic hepatitis B (CHB) is unknown. In a double-blinded, randomized, multi-center study we assessed histological changes in 110 hepatitis B e-antigen (HBeAg)-positive CHB patients treated for 52 weeks with Pegylated interferon alpha-2b (PEG-IFN) in combination with either lamivudine or placebo. Liver biopsies were taken before and at the end of treatment. All biopsies were blinded and scored according to the Ishak system., Results: Necroinflammatory score improved (defined as a decrease of at least two points) in 25 patients (48%) of the PEG-IFN/lamivudine combination therapy group and in 31 patients (53%) of the PEG-IFN monotherapy group. The fibrosis score improved (decrease of at least 1 point) in 17 patients (33%) of the combination therapy group vs. 13 patients (22%) of the PEG-IFN monotherapy group (P=0.23). Responders (n=42), defined as serum HBeAg negative at the end of therapy, showed a larger decline in necroinflammatory score than non-responders (mean decline 2.3 and 1.2 points, respectively, P=0.02). Among patients receiving PEG-IFN monotherapy necroinflammation improved more frequently in responders (78% of responders vs. 43% of non-responders, P=0.01) and in patients who showed normalization of ALT (76% of patients with normal ALT vs. 40% of patients with abnormal ALT, P=0.01). Fibrosis score in the PEG-IFN monotherapy group improved more often in responders (39%) than in non-responders (15%, P=0.04). In the PEG-IFN/lamivudine combination therapy group, we found no significant association between virological and biochemical endpoints and histological improvement., Conclusions: Treatment with PEG-IFN therapy improves liver necroinflammation in HBeAg-positive CHB patients, particularly in responders to therapy. PEG-IFN also improves fibrosis in responders. Addition of lamivudine to PEG-IFN did not further improve the histological outcome.
