Cytomegalovirus (CMV)

Record number: 
535
Adverse Occurrence type: 
MPHO Type: 
Estimated frequency: 
"the cumulative probability of CMV seroconversion was 0.31 by 36 days after first exposure to CMV-seropositive cadaver skin allografts". Five (22.7 percent) of 22 patients seroconverted during hospitalization at a mean of 34.2 days (25-46 days) after the burn and 26.7 days (21-42 days) after receipt of skin.
Time to detection: 
21-42 days
Alerting signals, symptoms, evidence of occurrence: 
A 1996 report of a study of 22 CMV negative burn patients who received skin allografts without regard to the donor's CMV serum status (90.9% of skin allografts were seropositive) showed that ski allografts can transmit CMV. They received CMV-seronegative blood products. Of 493 patients admitted from 1989 to 1993, 22 were CMV seronegative Five (22.7 percent) of 22 patients seroconverted during hospitalization at a mean of 34.2 days (25-46 days) after the burn and 26.7 days (21-42 days) after receipt of skin. One  of five had CMV pneumonia develop, two had CMV viruria develop, and three had persistent fever (>38.9 C), abnormal liver enzymes, and diarrhea not ascribable to bacterial or other viral agents. Another 4 patients became seropositive T 50, 163, 184, and 202 days after discharge but these were not considered as possible skin transmission cases.
Demonstration of imputability or root cause: 
Level 2. Likely, probable. CMV seroconversion after skin transplant, several with clinical disease consistent with CMV infection. No other viral or bacterial cause found
Imputability grade: 
1 Possible
