Fifty patients with congestive cardiomyopathy have been studied for evidence of previous Coxsackie B virus infection and compared with age- and sex-matched controls who had been admitted to hospital for investigation of other cardiac diseases. High neutralisation titres (greater than or equal to 1024) to Coxsackie B viruses were more common among the controls. On subdividing the patients according to their length of symptomatic history before study, high titres were more common only in those with a short history (less than or equal to 1 year). High titres were more common when there had been a febrile illness at the onset of symptoms. Endomyocardial biopsies of 18 patients disclosed no evidence of myocarditis, or, in 12 cases, of viral involvement. Although the evidence remains circumstantial, these results support the theory that Coxsackie B viruses may cause congestive cardiomyopathy and encourage further research into the mechanisms of myocardial cell damage by these visuses. ...
Coxsackievirus is a virus that belongs to a family of nonenveloped, linear, positive-sense single-stranded RNA viruses, Picornaviridae and the genus Enterovirus, which also includes poliovirus and echovirus. Enteroviruses are among the most common and important human pathogens, and ordinarily its members are transmitted by the fecal-oral route. Coxsackieviruses share many characteristics with poliovirus. With control of poliovirus infections in much of the world, more attention has been focused on understanding the nonpolio enteroviruses such as coxsackievirus. Coxsackieviruses are among the leading causes of aseptic meningitis (the other usual suspects being echovirus and mumps virus). The entry of coxsackievirus into cells, especially endothelial cells, is mediated by Coxsackie virus and adenovirus receptor. Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. Group A coxsackieviruses were noted to cause a flaccid ...
Coxsackie B4 Virus are enteroviruses that belong to the Picornaviridae family. These viruses can be found worldwide. They are positive-sense, single-stranded, non-enveloped RNA viruses with icosahedral geometry. Coxsackieviruses have two groups, A and B, each associated with different diseases. Coxsackievirus group A is known for causing hand-foot-and-mouth diseases while Group B, which contains six serotypes, can cause a varying range of symptoms like gastrointestinal distress myocarditis. Coxsackievirus B4 has a cell tropism for natural killer cells and pancreatic islet cells. Infection can lead to beta-cell apoptosis which increases the risk of insulitis. Coxsackievirus B4 is one of the six serotypes found in Group B and is a positive sense, single-stranded, non-enveloped RNA virus. Its genome is linear and is 7,293 nucleotides in length with both a 5 and 3 untranslated region and encodes its own 3 poly-A tail. The 5 untranslated region contains an internal ribosomal entry site (Type I ...
Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsackieviruses B1, B3, and B5. However, expression of human decay acceleration factor on the surface of nonpermissive murine fibroblasts led only to virus attachment without subsequent replication, and it was concluded that an additional cellular cofactor(s) is required to facilitate cell entry and subsequent replication.
Interest in CAR stems from its function as the primary high affinity receptor for Ad serotype 5, the most commonly used adenoviral vector in gene therapy protocols. CAR expression is the main determinant in gene transfer to normal tissue as ectopic expression of CAR in transgenic mice leads to several magnitudes of increase in adenovirus transducibility of tissues that are otherwise refractory to Ad-mediated gene expression [13-17]. As well, although decay accelerating factor (DAF, CD55) was the first described CVB receptor [18, 19], CAR is necessary and sufficient for CVB infection in vitro [20]. Thus, the expression levels of CAR may also govern the susceptibility to CVB diseases and the pathological consequences of CVB viral infection. In this context, acute viral myocarditis and myositis are inflammatory diseases affecting cardiac and skeletal muscle that can result from infection by the Coxsackie B virus. In both humans and rodents, heart is among the tissues showing the greatest abundance ...

Editorial comment: Cunningham and his associates determined whether enterovirus sequences were present in muscle biopsy specimens obtained from patients with PVFS. Two classes of probes were used: (i) so-called generic probes that were enterovirus group-specific; and (ii) probes that made it possible to determine whether virus RNA synthesis was asymmetrical (typical of cytic infection) or symmetrical (typical of defective viral RNA synthesis). Importantly, appropriate probes were used to test whether specimens also were positive for EBV sequences. Seventeen patients were studied that had fatigue for six or more months. Of these, five were mates and 13/17 were at midlife, i.e., 35-55 years of age. Then patients were tested for neutralizing antibody to Coxsackievirus B3; five were negative. Eleven patients were tested for IgM to Coxsackievirus B2, 3 and 5; of these, 10 were negative. Such results indicate that antibodies to Coxsackieviruses are not good surrogate markers for PVFS. When muscle ...

Infection of people with human immunodeficiency virus (HIV) as well as LP- BM5 infection in mice results in progressive deterioration of the immune system in the majority of untreated hosts. Peptide immunotherapy has been shown to be effective in the stimulation or immunoregulation of T-helper 1 (TH1) and T-helper 2 (TH2) response subsets. In murine acquired immunodeficiency syndrome (AIDS), TH1 deficiency enables the host to be susceptible to coxsackievirus infection, inducing cardiopathology in a short period. T-cell receptor (TCR) V 8.1 peptide, a 16-mer peptide containing the entire CFR1 segment and part of the FR2 region of human V 8, showed both an immunoregulating and immunostimulating effect in murine AIDS. TCR V 8.1 peptide acts on T cells promoting interleukin-2 production and therefore enhancing a cellmediated immune response. It retarded development of cardiopathology due to coxsackievirus infection. Retrovirus infected mice treated with the peptide showed a longer life span than the ...
腸道病毒(Enterovirus)又稱腸病毒,是一種主要寄生於腸道的正股單股RNA病毒,和人類及哺乳類的疾病有關。雖然名為腸病毒,在人類卻很少出現腸道的病狀。在病毒分類中,屬於第IV類的RNA病毒。腸道病毒的命名主要以它的英文名稱"Enterovirus"的英文簡寫"EV",再後綴以數字命名。例如,近年在亞洲和北美洲流行、可以引起手足口病的EV71就是其中的一種。 常見的腸病毒有克沙奇病毒,又稱柯薩奇病毒(Coxsackievirus groups A and B)有A型(甲型)23種與B型(乙型)6種,Echovirus伊科病毒31種,和造成小兒麻痺症的Poliovirus脊髓灰质炎病毒3種,以及不分類的腸病毒68~71型。共67種。 腸病毒全球皆有分布,而人類是唯一宿主及唯一感染源。腸病毒具高傳染性,主要經由兩途徑傳染,經由吃到被汙染的食物、水、玩具、口水等或經由呼吸道(飛沫、咳嗽 ...
In this study, we demonstrated for the first time that a cardiotropic enterovirus, CVB3, transiently induced proinflammatory cytokines, IL-6 and IL-8, in human myocardial fibroblasts, a simplified but species-specific model to detect both cytokine expression and actions of cytokines.21 25 Moreover, the kinetics of CVB3-induced cytokine expression in myocardial fibroblasts was clearly divergent from dermal fibroblasts (Figure 2⇑), indicating an organ-specific pattern of induction.. Previously, the expression of IL-1β, IL-4, IL-6, IL-8, and TNF-α had been demonstrated by RT-PCR in the myocardium of patients suffering from enterovirus myocarditis, cryptogenic myocarditis, and dilated cardiomyopathy,17 18 but neither the cytokine-expressing cells (myocardial or infiltrating) nor the stimulus (virus or secondary to infiltration) had been unequivocally identified. Recently, Seko et al26 compared the cytokine expression in murine CVB3 myocarditis with that of CVB3-infected murine heart cells in ...
Myocarditis is mainly caused by cardiotropic viruses. In recent time viruses found in endomyocardial biopsies mainly consist of parvovirus B19 (PVB19) and human herpesvirus 6 (HHV6). A definite causal link between virus-genome detection of PVB19 and/or HHV6 (via pcr techniques)and cardiac inflammation and dysfunction is however still missing.. Primary objective:. To determine the prevalence of PVB19 and HHV6 virus genome in heart muscle biopsies of cardiac surgery patients without clinical evidence of myocarditis or myocarditic sequelae. Secondary objectives:. ...
Type 1 diabetes (T1D) is characterized by the destruction of the insulin-producing β-cells of pancreatic islets. Genetic and environmental factors both contribute to T1D development. Viral infection with enteroviruses is a suspected trigger for T1D but a causal role remains unproven and controversial. Studies in animals are problematic because of species-specific differences in host cell susceptibility and immune responses to candidate viral pathogens such as coxsackie B virus (CVB). In order to resolve the controversial role of viruses in human T1D, we developed a viral infection model in immunodeficient mice bearing human islet grafts. Hyperglycemia was induced in mice by specific ablation of native β-cells. Human islets, which are naturally susceptible to CVB infection, were transplanted to restore normoglycemia. Transplanted mice were infected with CVB4 and monitored for hyperglycemia. Forty-seven percent of CVB4-infected mice developed hyperglycemia. Human islet grafts from infected mice

Kat: As Nancys daughter, I will never forget hearing the attending doctor quantifying my mother in such a morbid way, "On a scale of 1-10, 10 being drop dead instantly, you are like an 8.5". Impressed by how close my mother came to death, the doctor scribbled up whiteboard diagrams of her two massive saddle PEs, demonstrating how the obstructions kept the blood and oxygen from reaching her lungs. Seeing my mother in a hospital bed, skin completely gray, trying to comprehend all of it but looking so confused and defeated just broke my heart.. Nancy, how did you feel when you were first diagnosed?. I was terrified. Also, I felt confusion because I didnt totally understand the relationship between the clots and the compromised oxygen levels and the right heart strain. I just felt very overwhelmed at the diagnosis and upset that I hadnt known the risks beforehand.. Nancy, what was most important to your recovery and rehabilitation?. My daughter and my medical team were most important. PE/DVT can ...

Through the more recent advancements in CAD CAM a new, much more accurate, predictable workflow is now available for comprehensive cases. This does not necessarily replace a diagnostic wax up, but in many cases, it can. It involves milling of a CVB prior to fabrication of the definitive restoration. The protocol includes an intraoral try-in of a final case design prior to fabrication of the definitive restoration. By doing so, one can check intraorally all the essential design elements and parameters. A CVB is a milled PMMA (polymethyl methacrylate) try-in bridge. The CVB is essentially a milled acrylic bridge that is milled from a CAD design intended to be used for the final restoration. Once the try-in is performed and evaluated, the original CVB design can be brought back to the CAD stage and altered or tweaked as needed to insure predictability and accuracy of the final restoration. Here is how it works ...

Swine vesicular disease is a viral disease, characterized by the formation of vesicles and erosions, that affects only pigs. Although it can cause mild to severe illness, this infection is transient and not life-threatening. Its main significance is the strong resemblance to other vesicular diseases, particularly foot-and-mouth disease. Rapid differentiation of these diseases is critical, as the introduction of foot-andmouth disease could cause severe economic losses in non-endemic regions. In addition, the stability of swine vesicular disease virus in the environment complicates its eradication and makes prompt recognition essential for control.
Acute myocardial damage similar to that seen in human myocarditis occurs in BALB/c mice after infection with coxsackievirus B3 (CB3) or encephalomyocarditis virus (EMC). To investigate the role of antigen-specific T cells in the pathogenesis of this disorder, we compared CB3 disease expression in T cell-deficient, athymic nude (nu/nu) mice, in heterozygote (nu/+) mice with normal T cell function, and in nu/nu mice reconstituted with spleen cells from CB3- or EMC-infected nu/+ mice. Acute myocarditis occurred in both nu/nu and nu/+ mice. Severe myocarditis, however, developed only in nu/+ and nu/nu mice reconstituted with CB3-sensitized T cells, but not in those reconstituted with EMC-sensitized T cells. Myocardial virus titer and serum anti-CB3 antibody production were similar in nu/+ and nu/nu groups. Additionally, the presence of Thy 1.2 (pan T), Ly 1 (precursor of other T cell subsets), and Ly 2 (suppressor/cytotoxic T) positive cells was demonstrated in the myocardium in nu/+ and nu/nu mice ...

To clarify the role of TGF-β1 in myocardial healing process after virus-induced myocarditis, we have examined the time course of TGF-β1 expression and its localization in myocardial healing process after Coxsackie B3-induced murine myocarditis. TGF-β1 immunoreactivity increased in parallel with its mRNA level and reached a peak at 10 days after Coxsackie B3 virus inoculation. Immunohistochemically, TGF-β1 was localized at pre-necrotic area at an early phase (5 days); it increased and extended to the area around the necrotic foci when necrosis became manifest (10 days); it decreased when macrophages and fibroblasts migrated to the necrotic foci (15 days); and then it reached a normal level and localized a little in perivascular and calcified regions (30 days). To our knowledge, this is the first study which demonstrates that TGF-β1 mRNA increases in viral-induced myocarditis at acute inflammatory phase. This result suggests that TGF-β1 promotes the migration of macrophages and fibroblasts ...
Kids infected with enterovirus more likely to have type 1 diabetes A new research published in Diabetologia implies that children who have been infected with enterovirus are 48 percent more likely to are suffering from type 1 diabetes. The scholarly study is definitely by Dr Tsai Chung-Li, China Medical University, Taiwan, and colleagues proper dose . Type 1 diabetes is known as to be caused by complex conversation between genetic susceptibility, the disease fighting capability, and environmental elements, say the authors. Although cue for genetic predisposition has been elucidated, proof also points to involvement of enterovirus infection, including infections such as poliovirus, Coxsackievirus A, Coxsackievirus B, and echovirus. To investigate the link between EV an infection and subsequent type 1 diabetes, the researchers used nationwide population-based data from Taiwans national medical health insurance system.. ...

Dilated Cardiomyopathy is a chronic myocardial disease characterized by progressive depression of contractile function and ventricular dilatation. It is the leading cause of heart failure and the most common reason for heart transplantation. Besides genetic causes, viral infection and autoimmune response are considered to play a major role in the etiology of the disease. Among different viruses that cause the disease, Coxsackievirus B3 (CVB3) is predominantly associated with the development and progression of the disease. Moreover, Coxsackievirus induced myocarditis in the mouse mimics human myocarditis and dilated cardiomyopathy. In the murine model, the disease progresses over a period of 90 days from acute myocarditis to chronic myocarditis and further develops into dilated cardiomyopathy and congestive heart failure. Though much is known about the progression of the disease, the molecular events occurring after infection with CVB3 are not completely understood. In the current study, ...
