Disseminated human cytomegalovirus (CMV) disease occurs mainly as a congenital infection and among immunocompromised hosts. Patients with acquired immunodeficiency syndrome (AIDS) are at increased risk for CMV infection, and the most prevalent clinical manifestation is retinitis, followed by colitis, esophagitis, pneumonitis, and encephalitis. CMV oophoritis is poorly described in the literature with some cases reported in patients with hematological or solid malignancies, bone marrow or solid organ transplantation, immunosuppressive therapy, and advanced AIDS cases...

Background: Research on the biogenesis of tick-borne encephalitis virus (TBEV) would benefit gene therapy. Due to specific arrangements of genes along the TBEV genome, its viral-like particles (VLPs) could be exploited as shuttles to deliver their replicon, which carries therapeutic genes, to immune system cells. Objective: To develop a flaviviral vector for gene delivery as a part of gene therapy research that can be expressed in secretable VLP suicidal shuttles and provide abundant unique molecular and structural data supporting this gene therapy concept...

After being admitted to hospital with atypical chest pain, a 61-year-old woman was noted to become lethargic and confused. She also developed global dysphasia. MRI was suggestive of encephalitis, and lumbar puncture was positive for cytomegalovirus (CMV) PCR. The patient was treated with intravenous ganciclovir and subsequent oral valganciclovir and she gradually made a reasonable recovery. While this infection is usually closely linked to immunosuppression, the patient was found to be HIV negative, and was not on any immunosuppressive therapy...

Immunosenescence is characterised by reduced B and T cell responses. Evidence shows that booster vaccinations are less effective in elderly people, but data on the efficacy of primary immunisation are sparse. We conducted a monocentric, open label, phase IV trial to compare immune responses to primary vaccinations using the inactivated, adjuvanted Japanese Encephalitis vaccine by 30 elderly people (mean 69, range 61-78 years) and 30 younger people (mean 24, range 18-30 years). Humoral and cellular immune responses were analysed in relation to age and cytomegalovirus (CMV) seropositivity...

Cytomegalovirus (CMV) is a ubiquitous herpesvirus which establishes lifelong latency following primary infection. It is then capable of reactivating in the face of immunosuppression. Encephalitis is a less common, but particularly devastating syndrome associated with CMV. Here, we describe a case of CMV encephalitis in an allogeneic hematopoietic stem cell transplant recipient who received dual antiviral therapy with ganciclovir and foscarnet. The case presentation is followed by a summary of cases reported in the last ten years, with the goal of describing vulnerable patient populations, treatment courses, and outcomes...

Cytomegalovirus (CMV) is one of the opportunistic microorganisms with the highest prevalence in immunocompromised patients. Reactivation has decreased after the introduction of highly active antiretroviral therapy (HAART). Encephalitis has been reported in the coinfection as one of the most frequent presentations.We present the case of a young adult patient with HIV infection and rapid neurological deterioration due to classic clinical symptoms and signs of the Wernicke-Korsakoff syndrome, with no risk factors for thiamine deficiency, with images by nuclear magnetic resonance typical of the syndrome, and identification of cytomegalovirus in cerebrospinal fluid...

PURPOSE: Epilepsy is one of the most common primary brain disorders. Nonparaneoplastic autoimmune encephalitis is increasingly recognized as an important cause of adult onset epilepsy. However, only in rare cases an initiating factor of the syndrome can be identified. Autoantibody detection after central nervous herpesvirus infection indicates a postviral etiology in a subgroup of patients. In order to analyze a possible underrecognition of postinfectious autoimmunity we performed a large-scale analysis of herpesvirus DNA in cerebrospinal fluid samples from patients with clinical signs of autoimmune encephalitis...

In the swine industry, porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease which causes heavy economic losses worldwide. Effective prevention and disease control is an important issue. In this study, we described the construction of a Japanese encephalitis virus (JEV) DNA-based replicon with a cytomegalovirus (CMV) promoter based on the genome of Japanese encephalitis live vaccine virus SA14-14-2, which is capable of offering a potentially novel way to develop and produce vaccines against a major pathogen of global health...

Human herpesvirus 6 (HHV-6A and HHV-6B) can cause primary infection or reactivate from latency in liver transplant recipients, which can result in a variety of clinical syndromes, including fever, hepatitis, encephalitis and higher rates of graft dysfunction as well as indirect effects including increased risks of mortality, CMV disease, hepatitis C progression and greater fibrosis scores. Although HHV-6 infection is currently diagnosed by quantifying viral DNA in plasma or blood, biopsy to demonstrate histopathological effects of HHV-6 remains the gold standard for diagnosis of end-organ disease...

Despite the refinements in molecular methods for the detection of cytomegalovirus (CMV) and the advent of highly effective preemptive strategies, CMV remains a leading cause of morbidity and mortality in hematopoietic cell transplant (HCT) recipients. CMV can cause tissue-invasive disease including pneumonia, hepatitis, colitis, retinitis, and encephalitis. Mortality in HCT recipients with CMV disease can be as high as 60%. CMV infection has been associated with increased risk of secondary bacterial and fungal infections, increased risk of graft-versus-host disease, and high rates of non-relapse mortality following HCT...

Cytomegalovirus (CMV) is the most common infectious cause of brain defects and neurological dysfunction in developing human babies. Due to the teratogenicity and toxicity of available CMV antiviral agents, treatment options during early development are markedly limited. Valnoctamide (VCD), a neuroactive mood stabilizer with no known teratogenic activity, was recently demonstrated to have anti-CMV potential. However, it is not known whether this can be translated into an efficacious therapeutic effect to improve CMV-induced adverse neurological outcomes...

Japanese Encephalitis virus (JEV) is a mosquito-borne flavivirus with a positive-sense single-stranded RNA genome that contains a big open reading frame (ORF) flanked by 5'- and 3'- untranslated regions (UTRs). Nearly 30,000 JE cases with 10,000 deaths are still annually reported in East Asia. Although the JEV genotype III vaccine has been licensed, it elicits a lower protection against other genotypes. Moreover, no effective treatment for a JE case is developed. This study constructed a pBR322-based and cytomegaloviruses (CMV) promoter-driven JEV replicon for the production of JEV single-round infectious particles (SRIPs) in a packaging cell line expressing viral structural proteins...

BACKGROUND: Clinical reasoning in Neurology is based on general associations which help to deduce the site of the lesion. However, even "golden principles" may occasionally be deceptive. Here, we describe the case of subacute flaccid tetraparesis due to motor cortical lesions. To our knowledge, this is the first report to include an impressive illustration of nearly symmetric motor cortical involvement of encephalitis on brain MRI. CASE PRESENTATION: A 51 year old immunocompromized man developed a high-grade pure motor flaccid tetraparesis over few days...
