Cytomegalovirus esophagitis is a form of esophagitis associated with cytomegalovirus. [1] Symptoms include dysphagia , upper abdominal pain, diarrhea, nausea, vomiting, and sometimes hematemesis . This condition occurs in the setting of patients with a weakened immune system who are susceptible to both infections by CMV and the manifestation of ...
Children with symptomatic CMV have been found to have a greater incidence of long-term neurological and neurodevelopmental complications than children with fetal alcohol syndrome or down syndrome. [7] Congenital cytomegalovirus infection can be an important cause of intraventricular hemorrhage and neonatal encephalopathy. [12]
CMV colitis may be clinically manifested with diarrhea (usually non-bloody), abdominal pain, weight loss and anorexia. The diagnosis of CMV colitis is based on serology, CMV antigen testing and colonoscopy with biopsy. Clinical suspicion should be aroused in the setting of immunocompromised patient but it is much rarer in immunocompetent patient.
Cytomegalovirus (CMV) (from cyto-'cell' via Greek κύτος kútos - 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, [3] in the subfamily Betaherpesvirinae.
HHV-7 is a member of Betaherpesvirinae, a subfamily of the Herpesviridae that also includes HHV-6 and Cytomegalovirus (HHV-5 or HCMV). [3] [4] HHV-7 often acts together with HHV-6, and the viruses together are sometimes referred to by their genus, Roseolovirus. [5] HHV-7 was first isolated in 1990 from CD4+ T cells taken from peripheral blood ...
CMV infection or reactivation in people whose immune systems are compromised—for example people who have received transplants or are significantly burned—causes illness and increases the risk of death. [36] [37] CMV reactivation is commonly seen in people with severe colitis. [38] Specific disease entities recognized in those people are

Active viremia is caused by the replication of viruses which results in viruses being introduced into the bloodstream.Examples include the measles, in which primary viremia occurs in the epithelial lining of the respiratory tract before replicating and budding out of the cell basal layer (viral shedding), resulting in viruses budding into capillaries and blood vessels.
