P35.1 Congenital cytomegalovirus infection

Human cytomegalovirus (HCMV, Greek, cyto = "cell", megalo = "large") or Human Herpesvirus 5 (HHV-5) is a member of the herpes virus family. A viral infection that causes systemic infection and extensive brain damage and cell death by necrosis. Cytomegalovirus is the leading cause of congenital viral infection, with a range of incidence between 0·5–3% of live births worldwide. Approximately 30% of maternal infections during pregnancy can result in congenital infection. Neonates with congenital or perinatal cytomegalovirus infection can be asymptomatic and infection can also be transmitted postnatally from mother to infant by breastfeeding.
HCMV infection is ranked as one of the most common infections in adults, with the seropositive rates ranging from 60–99% globally. In Western countries, adults with advanced AIDS prior to the introduction of highly active antiretroviral therapy (HAART) this virus also a cause of blindness (CMV retinitis) and death in patients.
Congenital cytomegalovirus infection is also a cause of non-hereditary congenital sensorineural hearing loss.
Some Recent Findings
"Congenital cytomegalovirus (cCMV) infections are the most prevalent intrauterine infections worldwide and are the result of maternal primary or non-primary infections. Early maternal primary infections are thought to carry the highest risk of fetal developmental abnormalities as seen by ultrasound; however, non-primary infections may prove equally detrimental. METHODS/RESULTS: This case series presents 5 cases with fetal abnormalities detected in the second and third trimester, in which cCMV infection was ruled out due to negative maternal CMV-IgM. DISCUSSION: This series highlights the possible pitfalls in serology interpretation and fetal diagnosis necessary for appropriate parental counseling. Once fetal abnormalities have been confirmed and cCMV is suspected, maternal CMV serostatus and fetal infection should be determined. Maternal CMV serology may be ambiguous; therefore, caution should be exercised when interpreting the results."

A combination of tests has been used for prenatal diagnosis and there are some less reliable sonographic features to the infection.
- maternal serum - specific immunoglobulin (IgM) antibodies
- amniotic fluid - viral culture and PCR amplification of CMV DNA.
- 1921 - first to suggest that the "cytomegalia" could be due to a viral agent.
- 1950 - demonstrated that infection may occur in utero.
- 1956-57 - several groups independently isolate human CMV strains.
- 1960 - the term "cytomegalovirus" introduced.

Clinical term for the cytomegalovirus infection of the placenta.
A earlier histological study identified fixed connective tissue cells predominantly infected cell type in placental tissue. In addition, endothelial cells, macrophages and in some cases trophoblast infection. While a more recent in vitro study suggests that all villi cell types are likely to be infected.
