We report a case of early-onset acute Guillain-Barre syndrome associated with reactivation of Epstein-Barr virus (EBV) infection after nonmyeloablative stem cell transplantation (NST). Reactivation of EBV infection preceded disease onset, and the virus load increased concomitantly with disease progression (doubling time, 2.7 days). This case raises concern about the expanding scope of manifesta...

Hepatitis B virus (HBV) reactivation after chemotherapy or immunosuppressive therapy is a serious cause of liver-related morbidity and mortality. The mechanism of HBV reactivation is still unclear, but it is believed due to the suppression of immune response hence increasing the viral load. No uniform diagnostic criteria are available, HBV reactivation can be confirmed by an increase in serum H...

Drake, John W. (University of Illinois, Urbana). Multiplicity reactivation of Newcastle disease virus. J. Bacteriol. 84:352-356. 1962.-A very weak multiplicity reactivation occurs among Newcastle disease virus particles inactivated by ultraviolet irradiation. The preliminary steps in the infection of embryonic chicken fibroblasts are complex, and their relation to multiplicity reactivation is d...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

In this study, the effect of cholinergic or adrenergic inhibitors on the reactivation of latent Pseudorabies virus (PRV) was analyzed to clarify the mechanism of the reactivation of latent PRV by acetylcholine. For acetylcholine inhibition, latently infected mice were injected with scopolamine or succynilcholine before acetylcholine stimulation. For sympathetic blocking, mice were preinjected i...

In patients undergoing chemotherapy for the treatment of malignant disease, the reactivation of hepatitis B virus in hepatitis B surface antigen-positive patients has been frequently reported. However, activation has also been reported in hepatitis B surface antigen-negative patients who test positive for hepatitis B core antibody and/or hepatitis B surface antibody, who were thought to have ha...

Herpes simplex virus (HSV) infection is widespread in the human population. Following orofacial infection, HSV establishes latency in innervating sensory neurons, primarily located in the trigeminal ganglia. A central feature of HSV pathogenesis is the ability to periodically reactivate in those neurons and be transported back to the body surface. Both transmission and disease, such as keratiti...

Careful studies of mouse trigeminal ganglia (TG) latently infected with herpes simplex virus type 1 (HSV-1) indicate the presence of productive cycle viral gene products and persistent immune response, suggesting ongoing spontaneous viral reactivation in these tissues. In the present study we set out to determine whether infectious virus is present in murine TG latently infected with HSV-1 (KOS...

The varicella zoster virus primarily causes chickenpox. Herpes zoster is a typical late manifestation with reactivation of latent virus in sensory ganglia. Chickenpox is a highly contagious disease. Herpes zoster has been assumed to be less contagious, but studies have shown that reactivation of the varicella zoster virus also leads to significant spread of the virus (1–4). There has been incre...
