Autoimmune diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and primary Sjögren's syndrome (pSS) are complex disorders with a genetic background and the involvement of environmental factors, including viruses. The Epstein–Barr virus (EBV) is a plausible candidate for playing a role in the pathophysiology of these diseases. Both SLE and RA are characterized by high titers of anti-EBV antibodies and impaired T-cell responses to EBV antigens.
Abstract: To date, it is believed that the origin of autoimmune diseases is one of a multifactorial background. A genetic predisposition, an immune system malfunction or even backfire, hormonal regulation, and environmental factors all play important roles in the pathogenesis of autoimmune diseases. Among these environmental factors, the role of infection is known to be a major one.
Increasing evidence supports a link between Epstein-Barr virus (EBV), a ubiquitous B-lymphotropic human herpesvirus, and common B-cell–related autoimmune diseases. We sought evidence of EBV infection in thymuses from patients with myasthenia gravis (MG), an autoimmune disease characterized by intrathymic B-cell activation.
Seventeen MG thymuses (6 follicular hyperplastic,
Epstein-Barr virus (EBV), a ubiquitous B-lymphotropic herpesvirus, has been associated with multiple sclerosis (MS), an inflammatory disease of the central nervous system (CNS), but direct proof of its involvement in the disease is still missing. To test the idea that MS might result from perturbed EBV infection in the CNS, we investigated expression of EBV markers in postmortem brain tissue from MS cases with different clinical courses.
An 88-year-old man with autoimmune hemolytic anemia (AIHA) who had been treated with low dose prednisolone developed a sudden worsening of his anemia accompanied by reactivation of Epstein-Barr virus (EBV). We established EBV-infected spontaneous lymphoblastoid cell lines (LCL), performed an enzyme-linked immunosorbent spot assay, and confirmed a significantly suppressed EBV-specific cytotoxic T-cell (CTL) response to the LCL.
Objectives: To assess risk of a first clinical diagnosis of CNS demyelination (FCD) in relation to measures of Epstein-Barr virus (EBV) infection within the context of other known risk factors.
Methods: This was a multicenter incident case-control study. FCD cases (n = 282) aged 18–59 years and controls (n = 558,
Infections may act as environmental triggers for the induction of systemic lupus erythematosus (SLE). In this study, we determine the relationship between disease manifestations of SLE patients and the titers of five Epstein–Barr virus (EBV) Abs. We evaluated the titers of early antigen IgG (EAG), nuclear antigen IgG, viral capsid antigen (VCA) IgG and IgM,
In Graves' disease, the IgG class autoantibody against thyrotropin receptor (TRAb) is produced excessively and induces hyperthyroidism. Epstein-Barr virus (EBV) is one of the human herpesviruses that persists for life, mainly in B lymphocytes, and is occasionally reactivated. Therefore, EBV may affect the antibody production of B lymphocytes that would normally produce TRAb. The purpose of the present study was to evaluate the association of EBV reactivation with the etiology of Graves'
The role of viruses in the context of sudden infant death in early childhood is still unclear, although there are many findings pointing to a viral infection possibly leading to death.
To analyse the prevalence and viral loads of human herpesvirus-6 (HHV-6), Epstein-Barr virus (EBV),
To evaluate the effects of acute infection with Epstein–Barr virus (infectious mononucleosis, IM) on lipids and lipoproteins.
Fasting serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs), apolipoproteins (apo) A-I, B, E, C-II, C-III and lipoprotein (a) [Lp(a)] were determined in patients with IM on diagnosis and 4 months after the resolution of febrile illness and in age- and sex-matched controls.
