Cytomegalovirus (CMV) infection poses significant risks in allogeneic haematopoietic stem cell transplant (allo-HSCT) recipients. Despite advances in antiviral therapies, issues such as drug resistance, side effects, and inadequate immune reconstitution remain. This systematic review and meta-analysis aim to evaluate the efficacy and safety of adoptive cell therapy (ATC) in managing CMV infections in allo-HSCT recipients. Adhering to preferred reporting items for systematic reviews and meta-analyses guidelines, we conducted a comprehensive database search through July 2023. A systematic review and meta-analysis were conducted on studies involving HSCT patients with CMV infections treated with ATC. The primary outcome was the response rate to ATC, and secondary outcomes included adverse events associated with ATC. The Freeman-Tukey transformation was applied for analysis. In the meta-analysis of 40 studies involving 953 participants, ATC achieved an overall integrated response rate of 90.16%, with a complete response of 82.59% and a partial response of 22.95%. ATC source, HLA matching, steroid intake, and age group markedly influenced response rates. Donor-derived T-cell treatments exhibited a higher response rate (93.66%) compared to third-party sources (88.94%). HLA-matched patients demonstrated a response rate of 92.90%, while mismatched patients had a lower rate. Children showed a response rate of 83.40%, while adults had a notably higher rate of 98.46%. Adverse events were minimal, with graft-versus-host disease occurring in 24.32% of patients. ATC shows promising response rates in treating CMV infections post-HSCT, with an acceptable safety profile. However, to establish its efficacy conclusively and compare it with other antiviral treatments, randomised controlled trials are essential. Further research should prioritise such trials over observational and one-arm studies to provide robust evidence for clinical decision-making.

Vector-borne viruses pose a significant health problem worldwide, as they are transmitted to humans through the bite of infected arthropods such as mosquitoes and ticks. In recent years, emerging and re-emerging vector-borne diseases have gained attention as they can cause a wide spectrum of neurological manifestations. The neurological manifestations of vector-borne viruses encompass a board spectrum of clinical manifestations, ranging from mild and self-limiting symptoms to severe and life-threatening conditions. Common neurological complications include viral encephalitis, acute flaccid paralysis, aseptic meningitis, and various neuromuscular disorders. The specific viruses responsible for these neurological sequelae vary by geographic region and include Orthoflavivirus nilense, Zika virus, dengue virus, chikungunya virus, Japanese encephalitis virus, and tick-borne encephalitis virus. This review focuses on the pathogenesis of these neurologic complications and highlights the mechanisms by which vector-borne viruses invade the central nervous system and trigger neuroinflammatory responses. Diagnostic challenges and strategies for early detection of neurological manifestations are discussed, emphasising the importance of clinical suspicion and advanced laboratory testing.

This systematic review and meta-analysis aimed to compare the effectiveness and safety of azvudine versus nirmatrelvir/ritonavir (Paxlovid) in treating coronavirus disease 2019 (COVID-19). The researchers conducted searches on PubMed, Cochrane Library, Web of Science, medRxiv, and Google Scholar until January 2024. The Cochrane risk of bias tool was utilised to evaluate the quality of the included studies, and data analysis was performed using Comprehensive Meta-Analysis software. Thirteen studies, including 4949 patients, were analysed. The meta-analysis results showed no significant difference between the azvudine and Paxlovid groups in terms of mortality rate (odds rate [OR] = 0.84, 95% confidence interval [CI]: 0.59-1.21), negative polymerase chain reaction (PCR) conversion time (standard mean difference [SMD] = 1.52, 95% CI: -1.07-4.11), and hospital stay (SMD = -0.39, 95% CI: -1.12-0.33). However, a significant difference was observed between the two groups in terms of intensive care unit admission (OR = 0.42, 95% CI: 0.23-0.75) and the need for mechanical ventilation (OR = 0.61, 95% CI: 0.44-0.86) in favour of azvudine. The incidence of adverse events in the azvudine group was significantly lower (OR = 0.66, 95% CI: 0.43-0.99). The certainty of evidence was rated as low and moderate. Azvudine and Paxlovid demonstrated similar effectiveness in reducing mortality rates, negative PCR conversion time and hospital stay. However, azvudine showed better effectiveness in improving other outcomes. Regarding the level of certainty of evidence, further research is needed to validate or challenge these results.

Hodgkin lymphoma is histologically characterised by the presence of Hodgkin (H) and Reed-Sternberg (RS) cells originating from germinal centre B-cells rearranged in the IgV gene. The formation of multinucleated RS cells is a product of telomere organisation in a process initiated by telomere aggregate accumulation in mononuclear H cells and may be mediated by latent membrane protein 1 (LMP-1) expression. LMP-1 is the main oncoprotein of EBV and supports several tumourigenic processes. LMP-1 may rescue proapoptotic B-cells through downregulation of B-cell receptor (BCR) components, mimicking and inducing multiple distinct B-cell signalling pathways to promote proliferation and survival, such as Janus kinase-signal transducer and activator of transcription (JAK-STAT), nuclear factor-kappa b (NF-кB), and cellular MYC (c-MYC), and inducing telomere instability mainly through Telomere repeat binding factor 2 (TRF2) downregulation to promote the formation of multinucleated RS cells. This review presents recent discoveries regarding the influence of LMP-1 on the surviving cellular signalling, genomic instability and mecanical formation of HRS cells.
霍奇金淋巴瘤的组织学特征是存在霍奇金(H)细胞和里德-斯特恩伯格(RS)细胞,它们起源于IgV基因重排的生殖中心B细胞。多核RS细胞的形成是端粒组织化的产物,这一过程由端粒聚集体在单核H细胞中的聚集开始,并可能由潜伏膜蛋白1(LMP-1)的表达介导。LMP-1 是 EB 病毒的主要致癌蛋白,支持多种致瘤过程。LMP-1 可通过下调 B 细胞受体(BCR)成分、模拟和诱导多种不同的 B 细胞信号通路来促进增殖和存活,如 Janus 激酶-信号转导和转录激活因子(JAK-STAT),从而挽救促凋亡的 B 细胞、核因子-卡巴b(NF-кB)和细胞MYC(c-MYC),并主要通过端粒重复结合因子2(TRF2)下调诱导端粒不稳定性,从而促进多核RS细胞的形成。本综述介绍了有关 LMP-1 对存活的细胞信号、基因组不稳定性和 HRS 细胞机械形成的影响的最新发现。

Liver involvement is an unusual yet frequently overlooked dengue complication. Pivotal for an efficient clinical management, the early diagnosis of dengue-associated liver involvement relies on an accurate description of its clinical and biological characteristics, its prognosis factors, its association with severe dengue and its clinical management. We conducted a systematic review by searching PubMed and Web of Science databases for original case reports, cohort and cross-sectional studies reporting the clinical and/or biological features of dengue-associated liver involvement. The study was registered in PROSPERO (CRD42021262657). Of the 2552 articles identified, 167 were included. Dengue-associated liver involvement was characterised by clinical features including abdominal pain, hepatomegaly, jaundice, nausea/vomiting, and an echogenic liver exhibiting hepatocellular necrosis and minimal inflammation. Elevated Aspartate Aminotransferase and Alanine Aminotransferase but also elevated bilirubin, Alkaline Phosphatase, gamma-glutamyl transferase, increased International Normalised Ratio, creatinine and creatine kinase, lower albumin and prolonged prothrombin and activated partial thromboplastin time were prevalent in dengue-associated liver involvement. Cardiovascular and haematological systems were frequently affected, translating in a strong association with severe dengue. Liver involvement was more common in males and older adults. It was associated with dengue virus serotype-2 and secondary infections. Early paracetamol intake increased the risk of liver involvement, which clinical management was mostly conservative. In conclusion, this systematic review demonstrates that early monitoring of transaminases, clinical assessment, and ultrasound examination allow an efficient diagnosis of dengue-associated liver involvement, enabling the early identification and management of severe dengue.
肝脏受累是一种不常见但又经常被忽视的登革热并发症。登革热相关肝脏受累的早期诊断对有效的临床治疗至关重要,这依赖于对其临床和生物学特征、预后因素、与重症登革热的关联以及临床治疗的准确描述。我们通过检索 PubMed 和 Web of Science 数据库,对报告登革热相关肝脏受累的临床和/或生物学特征的原始病例报告、队列和横断面研究进行了系统性综述。该研究已在 PROSPERO(CRD42021262657)上注册。在确定的 2552 篇文章中,有 167 篇被纳入。登革热相关性肝脏受累的临床特征包括腹痛、肝肿大、黄疸、恶心/呕吐、肝脏回声呈肝细胞坏死和轻微炎症。在登革热相关性肝脏受累中,天冬氨酸氨基转移酶和丙氨酸氨基转移酶升高,胆红素、碱性磷酸酶、γ-谷氨酰转移酶也升高,国际标准化比率、肌酐和肌酸激酶升高,白蛋白降低,凝血酶原和活化部分凝血活酶时间延长。心血管和血液系统经常受到影响,这与重症登革热密切相关。肝脏受累在男性和老年人中更为常见。这与登革热病毒血清 2 型和继发感染有关。过早摄入扑热息痛会增加肝脏受累的风险,而临床治疗多为保守治疗。总之,本系统综述表明,通过早期监测转氨酶、临床评估和超声波检查,可以有效诊断登革热相关肝脏受累,从而及早发现和处理严重的登革热。

Congenital cytomegalovirus (cCMV) is among the most common congenital infections globally. Of 85%–90% cCMV‐infected infants without symptoms at birth, 10%–15% develop sequelae, most commonly sensorineural hearing loss (SNHL); their childhood neurodevelopmental outcomes are less well understood. Embase and MEDLINE were searched for publications from 16th September 2016 to 9th February 2024 to identify studies reporting primary data on neurodevelopmental outcomes in children with asymptomatic cCMV (AcCMV), measured using assessment tools or as evaluated by the study investigators, clinicians, educators, or parents. The Newcastle‐Ottawa scale was applied to studies to assess risk of bias. Of 28 studies from 18 mostly high‐income countries, there were 5‐109 children with AcCMV per study and 6/28 had a mean or median age at last follow‐up of ≥5 years. Children with AcCMV had better neurodevelopmental outcomes than children with symptomatic cCMV in 16/19 studies. Of 9/28 studies comparing AcCMV with CMV‐uninfected children, six reported similar outcomes whilst three reported differences limited to measures of full‐scale intelligence and receptive vocabulary among children with AcCMV and SNHL, or more generally in motor impairment. Common limitations of studies for our question were a lack of cCMV‐uninfected controls, heterogeneous definitions of AcCMV, lack of focus on neurodevelopment, selection bias and inadequate follow‐up. There was little evidence of children with AcCMV having worse neurodevelopmental outcomes than CMV‐uninfected children, but this conclusion is limited by study characteristics and quality; findings highlight the need for well‐designed and standardised approaches to investigate long‐term sequelae.

Global attention is riveted on neurodegenerative diseases due to their unresolved aetiologies and lack of efficacious therapies. Two key factors implicated include mitochondrial impairment and microglial ageing. Several viral infections, including Herpes simplex virus‐1 (HSV‐1), human immunodeficiency virus (HIV) and Epstein‐Barr virus, are linked to heightened risk of these disorders. Surprisingly, numerous studies indicate viruses induce these aforementioned precipitating events. Epstein‐Barr virus, Hepatitis C Virus, HIV, respiratory syncytial virus, HSV‐1, Japanese Encephalitis Virus, Zika virus and Enterovirus 71 specifically impact mitochondrial function, leading to mitochondrial malfunction. These vital organelles govern various cell activities and, under specific circumstances, trigger microglial ageing. This article explores the role of viral infections in elucidating the pathogenesis of neurodegenerative ailments. Various viruses instigate microglial ageing via mitochondrial destruction, causing senescent microglia to exhibit activated behaviour, thereby inducing neuroinflammation and contributing to neurodegeneration.

Influenza in dogs holds considerable public health significance due to their close companionship with humans, yet several facets of this phenomenon remain largely unexplored. This study undertook a systematic review and meta-analysis of observational studies to gauge the global seroprevalence of influenza in dogs. We also assessed whether pet dogs exhibited a higher seroprevalence of influenza compared to non-pet dogs, explored seasonal variations in seroprevalence, scrutinised the design and reporting standards of existing studies, and elucidated the geographical distribution of canine influenza virus (cIV). A comprehensive analysis of 97 studies spanning 27 countries revealed that seroprevalence of various influenza strains in dogs consistently registered below 10% and exhibited relative stability over the past decade. Significantly, we noted that seroprevalence of human influenza virus was notably higher in pet dogs compared to their non-pet counterparts, whereas seroprevalence of other influenza strains remained relatively uniform among both categories of dogs. Seasonal variations in seroprevalence of cIV were not observed. In summary, our findings indicated the global circulation of cIV strains H3N2 and H3N8, with other strains primarily confined to China. Given the lack of reported cases of the transmission of cIV from dogs to humans, our findings suggest a higher risk of reverse zoonosis than zoonosis. Finally, we strongly advocate for standardised reporting guidelines to underpin future canine influenza research endeavours.

Significantly, we noted that seroprevalence of human influenza virus was notably higher in pet dogs compared to their non-pet counterparts, whereas seroprevalence of other influenza strains remained relatively uniform among both categories of dogs. Seasonal variations in seroprevalence of cIV were not observed. In summary, our findings indicated the global circulation of cIV strains H3N2 and H3N8, with other strains primarily confined to China. Given the lack of reported cases of the transmission of cIV from dogs to humans, our findings suggest a higher risk of reverse zoonosis than zoonosis. Finally, we strongly advocate for standardised reporting guidelines to underpin future canine influenza research endeavours.</p>","PeriodicalId":21180,"journal":{"name":"Reviews in Medical Virology","volume":"34 3","pages":"e2542"},"PeriodicalIF":9.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140922973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the mankind counters the ongoing COVID-19 pandemic by the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), it simultaneously witnesses the emergence of mpox virus (MPXV) that signals at global spread and could potentially lead to another pandemic. Although MPXV has existed for more than 50 years now with most of the human cases being reported from the endemic West and Central African regions, the disease is recently being reported in non-endemic regions too that affect more than 50 countries. Controlling the spread of MPXV is important due to its potential danger of a global spread, causing severe morbidity and mortality. The article highlights the transmission dynamics, zoonosis potential, complication and mitigation strategies for MPXV infection, and concludes with suggested 'one health' approach for better management, control and prevention. Bibliometric analyses of the data extend the understanding and provide leads on the research trends, the global spread, and the need to revamp the critical research and healthcare interventions. Globally published mpox-related literature does not align well with endemic areas/regions of occurrence which should ideally have been the scenario. Such demographic and geographic gaps between the location of the research work and the endemic epicentres of the disease need to be bridged for greater and effective translation of the research outputs to pubic healthcare systems, it is suggested.

Cytomegalovirus (CMV) belongs to the Herpesviridae family and is also known as human herpesvirus type 5. It is a common virus that usually doesn't cause any symptoms in healthy individuals. However, once infected, the virus remains in the host's body for life and can reactivate when the host's immune system weakens. This virus has been linked to several neurological disorders, including Alzheimer's disease, Parkinson's disease, Autism spectrum disorder, Huntington's disease (HD), ataxia, Bell's palsy (BP), and brain tumours, which can cause a wide range of symptoms and challenges for those affected. CMV may influence inflammation, contribute to brain tissue damage, and elevate the risk of moderate-to-severe dementia. Multiple studies suggest a potential association between CMV and ataxia in various conditions, including Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, acute cerebellitis, etc. On the other hand, the evidence regarding CMV involvement in BP is conflicting, and also early indications of a link between CMV and HD were challenged by subsequent research disproving CMV's presence. This systematic review aims to comprehensively investigate any link between the pathogenesis of CMV and its potential role in neurological disorders and follows the preferred reporting items for systematic review and meta-analysis checklist. Despite significant research into the potential links between CMV infection and various neurological disorders, the direct cause-effect relationship is not fully understood and several gaps in knowledge persist. Therefore, continued research is necessary to gain a better understanding of the role of CMV in neurological disorders and potential treatment avenues.
