There is no cure for CMV, and treatment for CMV infection is not necessary in healthy children and adults. Those at very high risk of developing severe CMV infection may be placed on antiviral medication to help prevent CMV disease.
The majority of children born who experience a CMV infection before birth are healthy and normal. However, 10 to 15% may have complications such as hearing loss, neurological abnormalities, or decreased motor skills. Infants who are infected with CMV after they are born rarely experience any long-term complications.
If untreated, it can spread throughout the body, infecting organ after organ. It may cause respiratory problems, damage to the central nervous system, bleeding ulcers in the digestive system, and CMV retinitis, which can lead to blindness.
The IgG for CMV normal range is 620 to 1400 mg/dl.
If you're healthy, CMV mainly stays dormant. When the virus is active in your body, you can pass the virus to other people. The virus is spread through body fluids — including blood, urine, saliva, breast milk, tears, semen and vaginal fluids. Casual contact doesn't transmit CMV .
Cytomegalovirus OutlookThere's no cure for CMV. The virus stays inactive in your body and can cause more problems later. This reactivation is most common in people who've had stem cell and organ transplants.
High levels of IgG may mean a long-term (chronic) infection, such as HIV, is present. Levels of IgG also get higher in IgG multiple myeloma, long-term hepatitis, and multiple sclerosis (MS).
Although it's common, CMV is hard to catch.Spread through bodily fluids like urine, saliva, tears, semen, breast milk, mucus, and blood, CMV isn't airborne or considered to be highly contagious. “You don't get CMV from casual contact like riding the bus; it's from exchanging body fluids at an intimate level,” Dr.
If there is a 4-fold increase in IgG between the first and second sample, then you have an active CMV infection (primary or reactivated). A positive CMV IgM and negative IgG means you may have very recently been infected.
Reference range/unitsNormal Ranges Adult: IgG 6.0 - 16.0g/L. IgA 0.8 - 3.0g/L.
The initial screening test is a "total antibody test". Anybody who has ever been infected with CMV will have a positive total antibody test. If positive, we test further to detect which specific antibodies are elevated. If the infection is recent / active, the IgM antibody level will be elevated.
Primary CMV infection will cause up to 7 percent of cases of mononucleosis syndrome and will manifest symptoms almost indistinguishable from those of Epstein-Barr virus-induced mononucleosis. CMV, or heterophil-negative mononucleosis, is best diagnosed using a positive IgM serology.
People with CMV may pass the virus in body fluids, such as saliva, urine, blood, tears, semen, and breast milk. CMV is spread from an infected person in the following ways: From direct contact with saliva or urine, especially from babies and young children. Through sexual contact.
The drug of choice for treatment of CMV disease is intravenous ganciclovir, although valganciclovir may be used for nonsevere CMV treatment in selected cases. Ganciclovir is a nucleoside analogue that inhibits DNA synthesis in the same manner as acyclovir.
Most people recover in 4 to 6 weeks without medicine. Rest is needed, sometimes for a month or longer to regain full activity levels.
CMV IgM appears within the first 1 to 2 weeks after primary (new) infection; CMV IgG appears 1 to 2 weeks after IgM is detectable. IgG levels peak by 2 to 3 months post-infection and usually remain detectable for life.
Antiviral medications are the most common type of treatment. They can slow reproduction of the virus, but can't eliminate it. Researchers are studying new medications and vaccines to treat and prevent CMV .
Between 50% and 80% of adults in the United States have had a CMV infection by age 40. Once CMV is in a person's body, it stays there for life. CMV is spread through close contact with body fluids. Most people with CMV don't get sick and don't know that they've been infected.
CMV is the most common virus passed from mothers to babies during pregnancy. About 1 to 4 in 100 women (1 to 4 percent) have CMV during pregnancy. Most babies born with CMV don't have health problems caused by the virus. But CMV can cause problems for some babies, including microcephaly.
