Is the most common clinical manifestation of CMV?

Retinitis is the most common manifestation of CMV disease in patients who are HIV positive. It occurs most commonly in patients with CD4 counts below 50 cells/µL, with rates of up to 40% in this population. Affected patients report decreased visual acuity, floaters, and loss of visual fields on one side.

Can CMV cause neurological problems?

CMV produces neurological disease predominantly in infants with congenital infection. Although most congenital CMV infections are asymptomatic, many carriers develop sensorineural hearing loss and intellectual handicaps. Other neurological complications include microcephaly, seizures, hypotonia and spasticity.

Does HLH cause pain?

HLH patients have overactive histiocytes and lymphocytes, which are white blood cells that normally control infections, but when overactivated can cause swelling, redness, heat, pain and malfunction/damage of organs when they attack and accumulate in healthy lymph tissue (ed: Liver, Spleen, Lymph Nodes).

When do you suspect HLH?

HLH should be suspected in cases of an unexplained sudden onset of a systemic inflammatory response syndrome (SIRS), including fever, malaise, hepatosplenomegaly, jaundice, generalized lymphadenopathy, and cytopenias.

How does CMV affect the body?

Occasionally, CMV can cause mononucleosis or hepatitis (liver problem). People with weakened immune systems who get CMV can have more serious symptoms affecting the eyes, lungs, liver, esophagus, stomach, and intestines. Babies born with CMV can have brain, liver, spleen, lung, and growth problems.

How is CMV infection diagnosed?

The standard laboratory test for diagnosing congenital CMV infection is polymerase chain reaction (PCR) on saliva, with urine usually collected and tested for confirmation. The reason for the confirmatory test on urine is that most CMV seropositive mothers shed CMV in their breast milk.
