Extranodal NK/T-cell lymphoma (ENKTCL) is an Epstein-Barr virus (EBV)-related neoplasm with male dominance and a poor prognosis. A better understanding of the genetic alterations and their functional roles in ENKTCL could help improve patient stratification and treatments. Here, we performed comprehensive genetic analysis of 177 ENKTCL cases to delineate the landscape of mutations, copy number alterations (CNAs), and structural variations, identifying 34 driver genes including six previously unappreciated ones, namely HLA-B, HLA-C, ROBO1, CD58, POT1, and MAP2K1...

PURPOSE: To analyze the clinicopathologic information and CT imaging features of Epstein-Barr virus (EBV)-positive gastric cancer (GC) and establish CT-based radiomics models to predict the EBV status of GC. METHODS: This retrospective study included 144 GC cases, including 48 EBV-positive cases. Pathological and immunohistochemical information was collected. CT enlarged LN and morphological characteristics were also assessed. Radiomics models were constructed to predict the EBV status, including decision tree (DT), logistic regression (LR), random forest (RF), and support vector machine (SVM)...

Hemophagocytic lymphohistiocytosis (HLH), whether primary or secondary, is a rare and fatal clinical syndrome of uncontrolled immune activation and inflammatory cascade. Immune checkpoint inhibitors (ICIs) induced HLH has no standard diagnostic and treatment guidelines. Early diagnosis and appropriate treatment according to different disease backgrounds are crucial. Herein, we first report 2 cases of patients with chronic active Epstein-Barr virus infection (CAEBV) who developed HLH after the use of sintilimab, a monoclonal antibody against programmed cell death protein 1 (PD-1), and the DEP (liposomal doxorubicin, etoposide, methylprednisolone) chemotherapy regimen in combination with ruxolitinib were used to successfully control the disease...

BACKGROUND: The prognosis for advanced intrahepatic cholangiocarcinoma (iCCA) is poor, and there remains an urgent need to develop efficient systemic therapy. The efficacy of Pembrolizumab immunotherapy combined with lenvatinibin in iCCA is still unclear. The role of Epstein-Barr-virus (EBV) as a biomarker in iCCA for response to immunotherapy needs further exploration. CASE PRESENTATION: We report a case of a 60-year-old female with EBV-associated advanced iCCA (EBVaiCCA) who progressed after first-line therapy...

This MIB guide briefly summarizes the generation of patient-derived xenografts (PDXs) and highlights the importance of validating PDX models for the presence of B cell lymphoma of human origin before their use in radiotheranostic applications. The use of this protocol will allow researchers to learn different methods for screening PDX models for Epstein-Barr virus (EBV)-infected B cell lymphoma.

Epstein-Barr virus (EBV) can infect both B cells and epithelial cells (ECs), causing diseases such as mononucleosis and cancer. It enters ECs via Ephrin receptor A2 (EphA2). The function of interferon-induced transmembrane protein-1 (IFITM1) in EBV infection of ECs remains elusive. Here we report that IFITM1 inhibits EphA2-mediated EBV entry into ECs. RNA-sequencing and clinical sample analysis show reduced IFITM1 in EBV-positive ECs and a negative correlation between IFITM1 level and EBV copy number. IFITM1 depletion increases EBV infection and vice versa...

INTRODUCTION: Immune reconstitution (IR) kinetics of paediatric patients underwent haploidentical haematopoietic stem cell transplantation (HSCT) with post-transplant cyclophosphamide (PTCy) have not been extensively studied. We compared IR patterns of children receiving HSCT from haploidentical (n = 92) and HLA-matched donors (n = 36), and analysed risk factors for viral infection in these patients. METHODS: We prospectively measured lymphocyte subset numbers before HSCT and at 1, 3, 6 and 12 months after HSCT...

Primary myelofibrosis (PMF) is a rare myeloproliferative neoplasm characterized by elevated platelet counts and fibrous tissues in the bone marrow. The JAK1/2 inhibitor (JAKi), ruxolitinib, has demonstrated efficacy in reducing splenic size, alleviating myelofibrosis-related symptoms, and improving overall survival. While an increased risk of lymphoproliferative disease (LPD) is suggested in patients with PMF, particularly those treated with JAKi, the involvement of Epstein-Barr virus (EBV) in such cases remains poorly documented...

We present a clinical case of a 79-year-old male admitted to inpatient care for longstanding asthenia and respiratory symptoms. Associated features were polyserositis, multiple enlarged lymphatic nodules, acute kidney injury, and heart failure. The patient's recent medical history revealed SARS-CoV-2 vaccination a week prior and an upper respiratory tract infection. The laboratory results from thoracentesis were compatible with a transudate, with no immunological stain. Epstein-Barr virus polymerase chain reaction (PCR) was positive...

BACKGROUND: Metagenomic next-generation sequencing (mNGS) is a novel diagnostic tool increasingly used in the field of infectious diseases. Little guidance is available regarding its appropriate use in different patient populations and clinical syndromes. We aimed to review the clinical utility of mNGS in patients with a specific clinical syndrome and identify factors that may increase its utility. METHODS: We retrospectively reviewed charts of 72 non-immunocompromised adults hospitalized with the clinical syndrome of 'fever of undetermined origin' and underwent mNGS testing...

Extranodal natural killer/T-cell lymphoma-associated hemophagocytic lymphohistiocytosis (ENKTCL-LAHS) is a rare disease with poor prognosis. Currently, there are no well-established treatments for LAHS. Almost 50% of patients experience relapsed or refractory disease to anti-hemophagocytic lymphohistiocytosis (HLH) treatment, and the regimen for salvage therapy is limited. We report a case of ENKTCL-LAHS that was successfully treated with a programmed cell death ligand 1 (PD-L1) antibody (sugemalimab) alone and provide a literature review on existing ENKTCL-LAHS treatment options...

Reactivation or primary infection with double stranded DNA viruses is common in recipients of solid organ transplants and is associated with significant morbidity and mortality. Treatment with conventional anti-viral medications is limited by toxicities, resistance, and lack of effective options for adenovirus and BKPyV. Virus-specific T-cells (VSTs) have been shown to be an effective treatment for infections with adenovirus, BKPyV, cytomegalovirus (CMV), and Epstein-Barr virus (EBV). Most of these studies have been conducted in stem cell recipients and no large studies have been published in the solid organ transplant population to date...

A 66-year-old woman with rheumatoid arthritis (RA) who had been receiving methotrexate (MTX) for 2 years presented with tarry stools. Contrast-enhanced computed tomography (CT) of the abdomen revealed irregular wall thickening in the ileocecal region and multiple low-contrast masses in both lobes of the liver. Lower gastrointestinal endoscopy revealed a type 2 tumor in the ileocecal region with a semi-peripheral ulcer. Histological examination of liver and colon biopsies showed other iatrogenic immunodeficiency-associated lymphoproliferative disorder (Oi-LPD), diffuse large B-cell lymphoma type, with positivity for Epstein-Barr virus DNA...

Epstein-Barr virus (EBV) infection can lead to infectious mononucleosis (EBV-IM) and, more rarely, EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH), which is characterized by a life-threatening hyperinflammatory cytokine storm with immune dysregulation. Interferon-gamma (IFNγ) has been identified as a critical mediator for primary HLH; however, the detailed role of IFNγ and other cytokines in EBV-HLH is not fully understood. In this study, we used single-cell RNA sequencing to characterize the immune landscape of EBV-HLH and compared it with EBV-IM...
