Prediction of Cytomegalovirus (CMV) Reactivation in Intensive Care Unit (ICU) by Immunological Study

2016-07-27 03:38:21 | BioPortfolio

Summary

Cytomegalovirus is a herpesviridae whose prevalence in general population is between 50 to 80%. In immunocompetent individuals, CMV remains latent in a number of cells, without any pathological consequence. Immunosuppression may reactivate the virus causing either a CMV-active infection or a CMV disease with attributable symptoms.

In Intensive Care Unit (ICU), 6 to 30 % of critically ill patients without classical immunosuppression, as those suffering from septic shock, present CMV reactivation. Our aim is to study the risk factors for developing viremia or CMV disease in ICU patients in septic shock without previous immunodepression and determine the relationship between viral reactivation and this acquired immunity alteration.

Description

Immunosuppression statuses causing both CMV active infection or disease are mainly consecutive to HIV infection, bone marrow or solid organ transplantation. However, in severely ill patients, as in septic shock, it has been proved that after a hyper-inflammatory phase occurred a negative control of the immunity, resulting in a paralysed or impaired immune system. The length and extent of this immunodeficiency is correlated with the duration of ICU stay, the occurrence of nosocomial infection and mortality.

A better understanding of CMV's natural history reactivation in the critically ill patient would better define the benefits from a specific therapy.

Medical and Biotech [MESH] Definitions

Infection by a variety of fungi, usually through four possible mechanisms: superficial infection producing conjunctivitis, keratitis, or lacrimal obstruction; extension of infection from neighboring structures - skin, paranasal sinuses, nasopharynx; direct introduction during surgery or accidental penetrating trauma; or via the blood or lymphatic routes in patients with underlying mycoses.

A nontuberculous infection when occurring in humans. It is characterized by pulmonary disease, lymphadenitis in children, and systemic disease in AIDS patients. Mycobacterium avium-intracellulare infection of birds and swine results in tuberculosis.

Infection involving the tissues or organs in the PELVIS.

Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.

An infection at a specific location that may spread to another region of the body.
