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.

Background: This meta-analysis will evaluate the risk of hepatitis B reactivation in patients treated with ustekinumab for inflammatory bowel disease and psoriasis. We aim to determine the true incidence of this adverse event, reconcile discrepancies in reported reactivation rates, and elucidate the associated risk.

Methods: We conducted a rigorous systematic review adhering to established guidelines.

Multi-omic molecular characterization and diagnostic biomarkers for occult hepatitis B infection and HBsAg-positive hepatitis B infection.

Front Endocrinol (Lausanne)

November 2024

Department of Laboratory Medicine, The Affiliated Wuxi People's Hospital of Nanjing Medical University, Wuxi People's Hospital, Wuxi Medical Center, Nanjing Medical University, Wuxi, Jiangsu, China.

Background: The pathological and physiological characteristics between HBsAg-positive HBV infection and occult hepatitis B infection (OBI) are currently unclear. This study aimed to explore the immune microenvironment in the peripheral circulation of OBI patients through integration of proteomic and metabolomic sequencing, and to identify molecular biomarkers for clinical diagnosis of HBsAg-positive HBV and OBI.

Methods: This research involved collection of plasma from 20 patients with OBI (negative for HBsAg but positive for HBV DNA, with HBV DNA levels < 200 IU/mL), 20 patients with HBsAg-positive HBV infection, and 10 healthy individuals.

Clinical characteristics and long-term treatment outcomes of polypoidal choroidal vasculopathy with classic type leakage.

Sci Rep

September 2024

Department of Ophthalmology, Kim's Eye Hospital, #156 Youngdeungpo-dong 4ga, Youngdeungpo-gu, Seoul, 150-034, South Korea.

To investigate long-term treatment outcomes of polypoidal choroidal vasculopathy (PCV) with classic type leakage and to compare the outcomes with those of PCV without classic type leakage. This retrospective study included 153 patients diagnosed with PCV and treated with anti-vascular endothelial growth factor (VEGF). Patients showing classic type leakage on fluorescein angiography were included in the classic type leakage group (N = 40, 26.

What is the benefit of prophylaxis to prevent HBV reactivation in HBsAg-negative anti-HBc-positive patients? Meta-analysis and decision curve analysis.

Liver Int

November 2024

Department of Health Promotion, Section of Gastroenterology and Hepatology, Mother and Child Care, Internal Medicine and Medical Specialties, PROMISE, University of Palermo, Palermo, Italy.

Background And Aims: Patients with overt or occult hepatitis B virus (HBV) infection receiving immunosuppressive treatments have a wide risk of HBV reactivation (HBVr). We performed meta-analysis with decision curve analyses (DCA) to estimate the risk of HBVr in HBsAg-negative anti-HBc-positive patients naïve to nucleos(t)ide analogues (NAs) receiving immunosuppressive treatments.

Approach And Results: Studies were identified through literature search until October 2022.
