Article Abstract
Objectives: This prospective, pharmacokinetic study was done to investigate the impact of telaprevir plasma trough concentration (Ctrough) in the early stage of treatment on the response to telaprevir-based triple therapy for chronic hepatitis C patients.
Methods: Participants were 70 chronic hepatitis C patients infected with genotype 1. All patients received 12 week triple therapy that included telaprevir (2250 mg/day), pegylated interferon-α2b (pegylated-IFNα2b) (60-150 μg/week) and ribavirin (600-1000 mg/day) followed by a 12 week dual therapy that included pegylated-IFNα2b and ribavirin. Plasma telaprevir Ctrough was determined by a validated assay using HPLC at days 3, 7 and 14. The study was registered as a clinical trial on the University Hospital Medical Information Network (ID 000009656).
Results: The rates of undetectable hepatitis C virus RNA at week 4 [rapid virological response (RVR)] and at 24 weeks after therapy [sustained virological response (SVR)] were 71.4% and 82.9%, respectively. Of the patients with RVR, 90% achieved SVR. The mean telaprevir Ctrough levels at days 3, 7 and 14 of SVR patients (2.748, 2.733 and 2.999 μg/mL, respectively) were significantly higher than those of non-SVR patients (1.616, 1.788 and 2.314 μg/mL, respectively) (all P < 0.05). Multiple logistic regression analysis of possible predictors of SVR extracted higher telaprevir Ctrough at day 3 (OR 1.012 by 0.001 μg/mL, P < 0.0001) and interleukin 28B (rs8099917) TT allele (OR 6.16 versus non-TT alleles, P < 0.0001).
Conclusions: Therapeutic drug monitoring of telaprevir in the early stage of treatment is useful in clinical practice for predicting the virological response of patients receiving telaprevir-based triple therapy.

A Sleeping Giant: Late HBV Reactivation After Rituximab-Based Chemotherapy Despite Correct Prophylaxis.

Hepatitis B virus (HBV) reactivation is a recognized complication of long-term immunosuppressive or cytotoxic therapy, typically occurring during immunosuppression or within a few months after treatment. To mitigate this risk, hepatological societies recommend the use of nucleos(t)ide analogues (NA) for HBV reactivation prophylaxis, along with post-treatment monitoring; though, these recommendations are not universally consistent across different guidelines. We present a case of late HBV reactivation in a 76-year-old male with occult HBV infection who received rituximab-based therapy for chronic lymphocytic leukemia.

The prognosis of patients with liver failure (LF) depends significantly on the etiology and clinical indicators. This analysis of these basic indicators can help provide a basis for the study of predictive outcome indicators. We collected the data from multiple centers in Southeast China, including subclasses of acute liver failure (ALF), subacute liver failure (SLF), acute-on-chronic liver failure (ACLF), subacute-on-chronic liver failure (SALF), and chronic liver failure (CLF).

Hodgkin's lymphoma (HL) is a malignancy of the lymphocytes in the lymph nodes and presents with non-specific systemic symptoms like fever, night sweats, and weight loss. While HL often involves the mediastinum, it rarely causes superior vena cava (SVC) syndrome, and eosinophilia is noted in approximately 15% of cases. Here, we report a unique presentation of HL in a 52-year-old male with a history of chronic pruritus, chronic kidney disease, and inactive hepatitis B.

Hepatocellular carcinoma (HCC) is a major global burden, ranking as the third leading cause of cancer-related mortality. HCC due to chronic hepatitis B virus (HBV) or C virus (HCV) infection has decreased due to universal vaccination for HBV and effective antiviral therapy for both HBV and HCV, but HCC related to metabolic dysfunction associated steatotic liver disease (MASLD) and alcohol-associated liver disease (ALD) is increasing. Biannual liver ultrasonography and serum α-fetoprotein are the primary surveillance tools for early HCC detection among high-risk patients (e.

Background: Plasma pregenomic hepatitis B virus RNA (pgRNA) is a novel biomarker in chronic hepatitis B infection (CHB). We aimed to describe the longitudinal profile of pgRNA and factors influencing its levels in CHB patients on nucleoside analogue (NUC).
Methods: Serial plasma samples from 1354 CHB patients started on first-line NUC were evaluated.
