Scientists learn how common virus reactivates after transplantation
(Fred Hutchinson Cancer Research Center) A new study in Science challenges long-held theories of why a common virus -- cytomegalovirus, or CMV -- can reactivate and become a life-threatening infection in people with a compromised immune system, including blood cancer patients undergoing bone marrow transplantation.

Strain-specific antibody therapy prevents cytomegalovirus reactivation after transplantation
Cytomegalovirus infection is a frequent and life-threatening complication that significantly limits positive transplantation outcomes. We developed preclinical mouse models of cytomegalovirus reactivation after transplantation and found that humoral immunity is essential for preventing viral recrudescence. Preexisting antiviral antibodies decreased after transplant in the presence of graft-versus-host disease and were not replaced, owing to poor reconstitution of donor B cells and elimination of recipient plasma cells. Viral reactivation was prevented by the transfer of immune serum, without a need to identify and target s...

What are Some of the Causes of SGA?
Discussion
Intrauterine growth retardation or fetal growth retardation is due to a pathological process that causes decelerated fetal growth velocity. Small-for-gestational age (SGA) is an infant with growth parameters below the normal range for gestational age. More commonly, SGA is defined as a birth weight < 10% for gestational age. This may be due a pathological or non-pathological process (e.g. constitutionally small fetus). Using these standards, remember that 10% of all infants will be < 10% for weight, and they do not necessarily have an underlying problem and infants who are constitutionally small do not hav...

Infant HIV Infection Ups Risk for Congenital CMV Infection
THURSDAY, Oct. 25, 2018 -- HIV-exposed infants have high rates of congenital cytomegalovirus (cCMV) infection, and in utero HIV infection seems to be a major risk factor for cCMV, according to a study published in the October issue of The Pediatric... (Source: Drugs.com - Pharma News)

HIV-positive infants are at high risk for acquiring congenital cytomegalovirus infection
FINDINGSInfants born to HIV-positive mothers had high rates of congenital cytomegalovirus, or CMV. Infants who also were infected before birth by the virus that causes AIDS were especially prone to CMV infection.The researchers found that 23 percent of the infants who became infected with HIV during the mother ’s pregnancy also were infected with CMV; 18 percent who were infected with HIV either during pregnancy or birth acquired congenital CMV; and 4.9 percent who were exposed to HIV but remained uninfected with that virus also acquired congenital CMV.Overall, HIV-infected infants were four times as likely to have acqui...

Diseases Passed from Mom to Newborn Can Threaten Baby
Doctors say the transfer of an infection from a pregnant mother to a newborn can pose a serious threat to the baby, including deafness and a malformed brain. Three congenital infections — syphilis, cytomegalovirus (CMV), and HIV — are especially problematic in Texas, reports the July issue of Texas Medicine magazine. (Source: TMA News Room)
