Background: In accordance with the existing hypothesis, the application of an endobronchial valve (EbV) leads to selective curative atelectasis of the affected part of the lung, contributing to early closure of cavities.
Objective: To assess the effect of EbV treatment on the course of tuberculosis (TB).
Methods: We compared the efficacy of EbV treatment and complex second-line treatment in treating patients with destructive pulmonary multidrug-resistant TB (MDR-TB). Bacteriological conversion and closure of cavities were selected as criteria to assess the effectiveness of EbV application. A total of 102 patients with destructive MDR-TB were enrolled into the study and randomly divided into two groups: 49 patients had an EbV installed (intervention group) and 53 patients received complex second-line treatment (control group). Complex chemotherapy was administered to both groups throughout the study period.
Results: The cure rate in the short- and long-term follow-up periods in the intervention group was shown to be much higher, 95.9% by bacteriological conversion and 67.3% by cavity closure. On comparison with the control group, this was respectively 37.7% and 20.7% (P < 0.0001).
Conclusions: The application of EbV treatment can significantly improve the effectiveness of second-line chemotherapy regimens in MDR-TB patients.

Targeting EBV Episome for Anti-Cancer Therapy: Emerging Strategies and Challenges.

Program in Microbiology and Immunology, University of Pittsburgh, Pittsburgh, PA 15219, USA.
As a ubiquitous human pathogen, the Epstein-Barr virus (EBV) has established lifelong persistent infection in about 95% of the adult population. The EBV infection is associated with approximately 200,000 human cancer cases and 140,000 deaths per year. The presence of EBV in tumor cells provides a unique advantage in targeting the viral genome (also known as episome), to develop anti-cancer therapeutics.

Background: The Epstein-Barr virus (EBV) is intricately linked to a range of human malignancies, with EBV latent membrane protein 2A (LMP2A) emerging as a potential target antigen for immunotherapeutic strategies in the treatment of nasopharyngeal carcinoma (NPC).
Methods: The modified vaccinia virus Ankara (MVA) is universally used in vector vaccine research because of its excellent safety profile and highly efficient recombinant gene expression. Here, we constructed a novel MVA-LMP2A recombinant virus and investigated its specific immune response induction and oncolytic effect.
Encephalitis by Epstein Barr Virus in a Transplant Immunosuppressed Patient.

Laboratorio de Biología Molecular, Hospital Base de Valdivia, Valdivia, Chile.
Encephalitis due to Epstein-Barr Virus (EBV) is a rare condition that primarily affects children and immunosuppressed patients. Diagnosing EBV encephalitis can be challenging due to its nonspecific clinical presentation and the lack of confirmatory tests. We present the case of a 66-year-old woman with a history of kidney transplantation who was admitted due to progressive subacute mental deterioration, preceded by vertigo and without fever.

Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.
