Childhood adversity, defined in terms of material hardship or physical or emotional maltreatment has been associated with risk for infection with cytomegalovirus (CMV) among children and adolescents, and with CMV reactivation in children and adults. The present study examined whether different dimensions of childhood experience-those pertaining to socioeconomic status (SES), physical environmen...

BACKGROUND Hepatitis B virus (HBV) infections are common and associated with significant morbidity and mortality in cancer patients. However, the incidence and risk factors of HBV reactivation in patients with acute myeloid leukemia (AML) are rarely investigated. METHODS AML patients followed-up at the National Taiwan University Hospital between 2006 and 2012 were analyzed. The clinical chara...

A specific interleukin-1 (IL-1) receptor antagonist (IL-1ra) was used to examine the roles of IL-1 in an experimental model designed to analyze the reactivation phase of erosive arthritis, induced in rats with peptidoglycan-polysaccharide polymers (PG-APS) isolated from cell walls of group A streptococci. Monoarticular arthritis was initiated by injection of a small dose of PG-APS into an ankle...

Recent studies on the effect of stress on modulation of fear memory in our laboratory have uncovered endogenous opioid and adrenergic based modulation systems, working in concert, that limit the strengthening or weakening of newly acquired fear memory during consolidation under conditions of mild or intense stress, respectively. The present study sought to determine if similar stress-dependent ...

UNLABELLED Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of commonly fatal malignancies of immunocompromised individuals, including primary effusion lymphoma (PEL) and Kaposi's sarcoma (KS). A hallmark of all herpesviruses is their biphasic life cycle-viral latency and the productive lytic cycle-and it is well established that reactivation of the KSHV lytic cycle is asso...

INTRODUCTION Sepsis has been identified as a risk factor for human cytomegalovirus (CMV) reactivation in critically ill patients. However, the contribution of CMV reactivation on morbidity and mortality is still controversial. Therefore, we analyzed the incidence and impact of CMV reactivation on outcome in patients with severe sepsis. METHODS In a prospective longitudinal double-blinded obse...

The interplay between latent and lytic modes of infection is central to successful infection of all herpesviruses, yet knowledge of the determinants that govern reactivation of these viruses from latent to lytic infection is limited. Recently, several studies have identified roles for specific cellular microRNAs in inhibiting reactivation of various herpesviruses, thereby promoting latent infec...

Reactivation of chronic Chagas' disease is a rare condition and occurs only in immunosuppressed patients. We report a case of a patient with a rapid and fatal reactivation of Chagas' disease, manifested by meningoencephalitis, which lead to a diagnosis of acquired immunodeficiency syndrome (AIDS). We believe there is sufficient evidence to include the reactivation of Chagas' disease among the d...

(CMV) reactivation has been widely documented in the past 10 years in critically ill patients [1]. Conversely, few data are available on burn patients despite experimental studies showing that these patients are predisposed to herpes virus infections [2]. To our knowledge, only two studies reported the incidence of CMV infection in burn patients using a modern technique , such as PCR, which has...

Sensory ganglia latently infected with herpes simplex virus (HSV) were transplanted beneath the renal capsule of syngeneic recipients, and the latent infection remaining was investigated. HSV latency-associated transcript (LAT) expression and reactivation of HSV after explant of transplanted dorsal root ganglia were monitored as markers of latency. Two to four weeks after transplantation, both ...
