Cytomegalovirus (CMV) reactivation may be a cause of acute exacerbations in patients with severe ulcerative colitis (UC). Patients with exacerbation of symptoms by CMV have greater morbidity and mortality rate. The present study was conducted to evaluate the prevalence of CMV infection in UC patients by endoscopic examination, histopathological examination and CMV DNA PCR of colonic mucosal biopsy tissue and also to identify the associated risk factors and clinical outcomes.

Acute myeloid leukemia (AML) that is relapsed and/or refractory post-allogeneic hematopoietic cell transplantation (HCT) is usually fatal. In a prior study, we demonstrated that AML relapse in high-risk patients was prevented by post-HCT immunotherapy with Epstein-Barr virus (EBV)-specific donor CD8 T cells engineered to express a high-affinity Wilms Tumor Antigen 1 (WT1)-specific T-cell receptor (TTCR- C4). However, in the present study, infusion of EBV- or Cytomegalovirus (CMV)-specific T did not clearly improve outcomes in fifteen patients with active disease post-HCT.

Liver transplantation (LT) is a cost-effective therapy for advanced liver disease. Although LT significantly improves long-term survival, it requires strict control of immunosuppressants and their potential complications. Several available immunosuppressive drugs include glucocorticoids, calcineurin inhibitors, mycophenolate, mTOR inhibitors, and anti-CD25 antibodies.

Article Synopsis
- Advances in cancer immunotherapy face challenges with patient resistance and relapses, prompting exploration of bispecific antibodies like NI-3201, designed to enhance T-cell activation against tumors.
- NI-3201 works by blocking the PD-L1/PD-1 pathway and providing additional T-cell stimulation through CD28, showing promising in vitro and in vivo results for tumor regression and immune memory.
- Preclinical safety assessments indicate good tolerability, and future studies aim to further investigate NI-3201's potential in improving outcomes for patients with PD-L1+ solid tumors.

Studies investigating the impact of donor cytomegalovirus (CMV) positivity on the prognosis of liver transplantation (LT) recipients with HCC are currently lacking. A total of 21 759 eligible LT recipients were identified in the UNOS database between January 2002 and June 2023. The patients were divided into the donor CMV-seronegative (n = 7575) and CMV-seropositive (n = 14 814) groups.

Introduction: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients are severely immunocompromised and susceptible to bacterial, viral, and fungal infections. Despite improved anti-microbial prophylaxis and preemptive strategies, bacterial bloodstream infections (BSIs) occur frequently in allo-HSCT recipients and are associated with increased morbidity and mortality. Cytomegalovirus (CMV) and Epstein Barr virus (EBV) are the most relevant viruses following allo-HSCT and remain major concerns.
