Introducción. El citomegalovirus es la causa más frecuente de infección en pacientes con trasplante renal. Existen dos estrategias de similar efectividad para prevenirlo: la profilaxis universal con valganciclovir durante 90 días o el tratamiento anticipado verificando la carga viral semanal y aplicándolo solo si esta es positiva.Objetivo. Determinar cuál de estas dos estrategias sería más costo-efectiva en pacientes de riesgo intermedio en Colombia.Materiales y métodos. Se diseñó un árbol de decisiones bajo la perspectiva del tercer pagador considerando únicamente los costos médicos directos en pesos colombianos (COP) del 2014 durante un periodo de un año en una población de pacientes con riesgo intermedio para citomegalovirus (donante positivo y receptor positivo, o donante negativo y receptor positivo)...

Despite the frequency of infections with herpesviridae family, only eight subtypes affect humans (Herpex Simplex Virus types 1 and 2, Varicella Zoster Virus, Epstein-Barr Virus, Citomegalovirus and Human Herpes Virus types 6, 7 and 8). Amongst enteroviruses infections, the most important are Poliovirus, Coxackievirus and Echovirus. Symptoms can vary from mild to severe and early diagnosis is of upmost importance. Nowadays, low-density arrays can detect different types of viruses in a single assay using DNA extracted from biological samples...

Q fever which is caused by Coxiella burnetii, is a worldwide zoonosis. Many species of wild and domestic mammals, birds, and arthropods, are reservoirs of C.burnetii in nature, however farm animals are the most frequent sources of human infection. The most frequent way of transmission is by inhalation of contaminated aerosols. The clinical presentation of Q fever is polymorphic and nonspecific. Q fever may present as acute or chronic disease. In acute cases, the most common clinical syndromes are selflimited febrile illness, granulomatous hepatitis, and pneumonia, but it can also be asymptomatic...

Current graft-versus-host disease (GVHD) inhibition approaches lead to abrogation of pathogen-specific T-cell responses. We propose an approach to inhibit GVHD without hampering immunity against pathogens: in vitro depletion of alloreactive T cells with the preoteasome inhibitor bortezomib. We show that PBMCs stimulated with allogeneic cells and treated with bortezomib greatly reduce their ability to produce IFN-γ when re-stimulated with the same allogeneic cells, but mainly preserve their ability to respond to citomegalovirus stimulation...

Cytomegalovirus (CMV) is a β herpesvirus and a significant human pathogen. After primary infection establishes life long latency. In immunocompetent individuals cell-mediated host immune responses prevent the development of overt CMV disease. It has increasingly come to be recognized that critically ill patients are at risk for CMV reactivation from the latency. The risk factors associated to CMV reactivation in the critically ill are infection, sepsis, trauma, transfusions, major surgery, prolonged mechanical ventilation, steroids and vasopressors...

Human citomegalovirus (CMV) is a beta-herpesvirus able to establish lifelong persistent infections which usually remain asymptomatic. However, severe diseases may develop in immunocompromised subjects (e.g., AIDS patients and transplant recipients) and if acquired in utero. Circulating CMV clinical strains display genetic polymorphisms in multiple genes, which may be implicated in CMV-induced immunopathogenesis, as well as strain-specific tissue-tropism, viral spread in the host cells and virulence, finally determining the wide spectrum of clinical manifestations of CMV disease...

Postnatal cytomegalovirus (CMV) infection in the newborn can occur from exposure to maternal cervical secretions during birth, ingestion of breast milk, transfusion of blood products or transmission by body fluids of infected people. Breast milk is the main source of infection, given the high rate of CMV-positive mothers excreting CMV in milk. Freezing reduces the risk of CMV transmission by breastfeeding, although it does not eliminate it completely. Pasteurisation prevents such transmission, but it can alter the immunological properties of breast milk...

Epstein-Barr virus (EBV) and Citomegalovirus (CMV) are Herpesviridae family representative and presents a real danger for human. A very high infect risk of population farther the danger The ocular pathology induced by them can affect all media and tunics of optic analyzer. An etiologic differentiation is necessary for the mentioned viruses induced diseases. The etiologic differentiation has like purpose the enforcement of an effective and optimal antiviral and immunomodulating therapy.

Cytomegalovirus (CMV) is the leading cause of congenital infection in developed countries, affecting 0.3 to 0.6% of all live births in Europe. Primary CMV infection occurs in 1 to 4% of seronegative women during pregnancy and may be transmitted to the fetus in 40% of cases. Up to 10% of intrauterine CMV infections result in symptomatic congenital disease at birth. Half of these children and 13% of those born with asymptomatic infection will develop long-term sequelae, especially neurosensory hearing loss and mental retardation...

Congenital infections are among the most pressing health care problems. Congenital infections are not reason of congenital malformation and perinatal mortality only, but also pathologies that can be revealed during first year of life. Frequency for congenital viral infection displayed from birth varies between 23% and 92%. The aim of the study was the investigation of inherent infection consequences (citomegaloviral infection, herpes infection and chlamidia) in children in different age groups. Under our observation were 81 children with congenital infections...

INTRODUCTION: Aneurysms, described in pediatric AIDS, are related with bad prognosis with high mortality in 5 months. The twenty reports found in literature were considered late (mean age 9.97 years old) and associated with severe immunological involvement. The mean CD-4 count was 79.17 cells and mean viral load 222,662 copies/mL. Some authors consider this complication associated to the human immunodeficiency virus (HIV), to an opportunistic agent (citomegalovirus and Mycobacterium avium) or due to inflammatory mechanisms related with the immunological improvement...

Although the incidence of most central nervous system infections in HIV+ patients has decreased after the introduction of the modern antiretroviral treatments, they are still a major cause of morbidity and mortality. New technologies in molecular biology and neuroradiology establish the diagnosis in many cases and have decreased the need for cerebral biopsy. Prognosis has improved substantially after the introduction of high activity antiretroviral treatment; more active treatments are needed, however, for infections as PML or citomegalovirus encephalitis because of their still unacceptably high mortality...
