Incidence of Rash After Amoxicillin Treatment in Children With Infectious Mononucleosis
Antibiotics-induced rash in Epstein-Barr virus acute infectious mononucleosis, especially the aminopenicillins-induced type, was first described during the 1960s, with a reported incidence of 80% to 100%. This phenomenon was not further investigated but is well-established in pediatric textbooks. The main observation of this study is that rash induced by amoxicillin in confirmed Epstein-Barr virus acute infectious mononucleosis was found at a rate of ~30%, which is much lower than previously reported.

Frequent Mutations in SH2D1A (XLP) in Males Presenting With High‐Grade Mature B‐Cell Neoplasms
Abstract X‐linked lymphoproliferative syndrome (XLP) is caused by mutations in SH2D1A, and is associated with overwhelming infectious mononucleosis, aplastic anemia, hypogammaglobulinemia, and B‐cell lymphomas. However, the frequency of SH2D1A mutations in males who present with B NHL is unknown. Five cases of XLP were diagnosed among 158 males presenting with B NHL (approximately 3.2%). Four of the patients had two episodes of B NHL and one had a single episode of B NHL followed by aggressive infectious mononucleosis. Prospective screening for XLP in males with B‐cell lymphoma at the time of initial diagnosis should...

Hemophagocytic Lymphohistiocytosis--A Diagnostic Dilemma: Two Cases and Review
Hemophagocytic lymphohistiocytosis (HLH) is a severe inflammatory disorder characterized by activation and proliferation of lymphocytes and histiocytes with cytokine release and uncontrolled hemophagocytosis, especially late in the course of the disease. Clinical features include relapsing fevers, hepatosplenomegaly, cytopenias, lymphadenopathy, and coagulopathy. The diagnosis can be challenging, as the early signs and symptoms are nonspecific and no specific laboratory tests exist. This syndrome is frequently not recognized and has a significant mortality rate. Typical scenarios in which HLH should be considered include m...

Sex ratio of infectious mononucleosis and possible relevance to multiple sclerosis
Infectious mononucleosis (IM) is associated with the risk of developing multiple sclerosis (MS). Using databases of hospital admissions for England (1999–2005), we investigated the female-to-male ratios (FMRs) for admission to hospital for IM and MS stratified by age. Males were more frequently admitted for IM for all age groups apart from ages 10–14 (FMR 1.50; 95% confidence interval (CI) 1.36–1.64) and, borderline significantly, at ages 15–19 (FMR 1.03, 95% CI 0.99–1.08). This intriguing aspect of IM epidemiology in adolescence, the atypical female excess, may be linked to the sex ratio of M...

Acyclovir Reduces the Duration of Fever in Patients with Infectious Mononucleosis-like Illness.
Abstract Acyclovir is known for its antiviral activity against some pathogenic viruses such as the Epstein-Barr virus (EBV) that causes infectious mononucleosis (IM) and IM-like illness. Therefore, we empirically administered acyclovir to patients with suspected EBV-IM and IM like-illness, upon their admission to our hospital. We admitted 25 patients, who were hospitalized for fever and lymphadenopathy, to the Tohoku University Hospital Infectious Disease Ward. As part of treatment, 8 of these patients were given acyclovir (750 mg/day) with their consent and were assigned to the acyclovir group; the remaining 17 pa...

Cytokine profiles in children with primary Epstein–Barr virus infection
Abstract Primary Epstein–Barr virus (EBV) infection causes infectious mononucleosis and hemophagocytic lymphohistiocytosis (HLH) in children, where EBV infects B and CD8+ T cells, respectively. We measured pro‐inflammatory and anti‐inflammatory cytokines in both diseases. Significantly higher concentrations of various mediators, including interferon‐γ, neopterin, interleukin (IL)‐6, IL‐10, IL‐18, and heme oxygenase‐1, were observed in EBV‐HLH. Because of their similarity to the profile of familial HLH, this profile was likely a consequence of HLH, but not ectopic infection. TNF‐α levels were elevated ...

Use of complement regulators, CD35, CD46, CD55, and CD59, on leukocytes as markers for diagnosis of viral and bacterial infections.
Abstract Several complement regulatory proteins exist on self-cells to prevent damage by the serum complement system. In the present study, we aimed to perform quantitative analysis of membrane-bound complement regulators, CR1 (CD35), MCP (CD46), DAF (CD55), and MIRL (CD59), on peripheral blood neutrophils, monocytes, and lymphocytes from healthy controls (n = 36) and febrile patients diagnosed with either bacterial (n = 21) or viral (n = 26) infections. Our results show that: a) increased CD35 and CD55 levels on neutrophils and monocytes present potent markers of bacterial infection, b) increased expression of CD4...

Epstein–Barr Virus Infection and Posttransplant Lymphoproliferative Disorder
Epstein–Barr virus (EBV) is an important pathogen in recipients of solid organ transplants (SOT). Infection with EBV manifests as a spectrum of diseases/malignancies ranging from asymptomatic viremia through infectious mononucleosis to posttransplant lymphoproliferative disorder (PTLD). EBV disease and its associated PTLD is more frequently seen when primary EBV infection occurs after transplant, a common scenario in pediatric SOT recipients. Intensity of immunosuppressive therapies also influences the risk for PTLD. The use of EBV viral load monitoring facilitates the diagnosis and management of EBV/PTLD as well as bein...

Characterization of Epstein–Barr virus reactivation in a modeled spaceflight system
Abstract Epstein–Barr virus (EBV) is the causative agent of mononucleosis and is also associated with several malignancies, including Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma, among others. EBV reactivates during spaceflight, with EBV shedding in saliva increasing to levels ten times those observed pre‐and post‐flight. Although stress has been shown to increase reactivation of EBV, other factors such as radiation and microgravity have been hypothesized to contribute to reactivation in space. We used a modeled spaceflight environment to evaluate the influence of radiation and microgravity o...

Epstein–barr virus associated acute hepatitis with cross‐reacting antibodies to other herpes viruses in immunocompetent patients: Report of two cases
Abstract Epstein–Barr virus (EBV) is the causative agent of infectious mononucleosis (IM) which is characterized by the triad of fever, sore throat, and lymphadenopathy. Self‐limited, mild liver function test abnormalities are seen in IM. Acute hepatitis in primary EBV infection is uncommon. Serum transaminases are elevated but are less than fivefold the normal levels in most cases and rarely exceed 10 times the normal levels in primary EBV infections especially in elderly. Laboratory diagnosis of acute EBV infection is by serological assays confirming the presence of EBV viral capsid antigen (VCA) IgM antibodies. Due ...

LMP1 promoter sequence analysis in Epstein Barr virus pediatric infection reveals preferential circulation of B95.8 related variants in Argentina.
Abstract The Epstein Barr virus (EBV) is associated with several lymphoid and epithelial malignancies such as Hodgkin and Burkitt lymphoma or nasopharyngeal carcinoma and it is also the etiological agent of infectious mononucleosis (IM). Transcriptional regulation of the viral oncoprotein LMP1, remains yet not fully understood. LMP1 expression can be initiated in an EBNA2 dependent or independent manner from ED-L1 or LT-R1 promoters. It has been proposed that sequence variation at ED-L1 region could be an important factor concerning LMP1 expression. In order to characterize the natural sequence variation of the ED-...

Simultaneous detection of the two main proliferation driving EBV encoded proteins, EBNA-2 and LMP-1 in single B cells.
Abstract Epstein Barr virus (EBV) is carried by almost all adults, mostly without clinical manifestations. Latent virus infection of B lymphocytes induces activation and proliferation that can be demonstrated in vitro. In healthy individuals, generation of EBV induced malignant proliferation is avoided by continuous immunological surveillance. The proliferation inducing set of the virally encoded genes is expressed exclusively in B cells in a defined differentiation window. It comprises nine EBV encoded nuclear proteins, EBNA 1-6, and three cell membrane associated proteins, LMP-1, 2A and 2B, designated as latency ...

EBV primary infection in childhood and its relation to B‐cell lymphoma development: A mini‐review from a developing region
Abstract In most underdeveloped countries the initial contact with Epstein Barr virus (EBV) usually happens in the first decade of life and results in an asymptomatic infection, while in developed areas primary infection in adolescence or adulthood is accompanied by infectious mononucleosis in 50% cases. Although it is generally a harmless passenger, in some individuals, it is associated with B‐cell lymphoma. In Argentina, EBV primary infection shows the classical pattern observed in developing populations, given that nearly 70% of patients are seropositive by the age of 2 years. However, EBV association with paediatric ...

Characterization of Epstein‐Barr virus reactivation in a modeled spaceflight system
Abstract Epstein‐Barr virus (EBV) is the causative agent of mononucleosis and is also associated with several malignancies, including Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma, among others. EBV reactivates during spaceflight, with EBV shedding in saliva increasing to levels ten times those observed pre‐and post‐flight. Although stress has been shown to increase reactivation of EBV, other factors such as radiation and microgravity have been hypothesized to contribute to reactivation in space. We used a modeled spaceflight environment to evaluate the influence of radiation and microgravity o...

Updates in immunoassays: virology.
Abstract Virus identification is a challenge to the clinical microbiologist since growing viruses in traditional cell culture is labor intensive, time consuming, and subject to contamination. The advent of rapid and automated immunoassays has eliminated this problem by generating positive results in minutes to hours. For example, testing for infectious mononucleosis can yield a positive result in 3-8 minutes as seen with the Beckman Coulter, Inc. ICON Mono test or in 5-15 minutes with the MONO Mononucleosis Rapid Test Device marketed by ACON Laboratories, Inc. Fully automated immunoassay analyzers provide fast, acc...

Resveratrol inhibits Epstein Barr Virus lytic cycle in Burkitt's lymphoma cells by affecting multiple molecular targets.
In this study, we examined the antiviral activity of RV against the EBV replicative cycle and investigated the molecular targets possibly involved. In a cellular context that allows in vitro EBV activation and lytic cycle progression through mechanisms closely resembling those that in vivo initiate and enable productive infection, we found that RV inhibited EBV lytic genes expression and the production of viral particles in a dose-dependent manner. We demonstrated that RV inhibited protein synthesis, decreased reactive oxygen species (ROS) levels, and suppressed the EBV-induced activation of the redox-sensitive transcripti...
