Rapid shell vial culture and tissue histology compared with serology for the rapid diagnosis of cytomegalovirus infection in liver transplantation.
Sixty-six patients who had undergone 78 liver transplantations, with no detectable cytomegalovirus (CMV) infection before transplantation, were studied to assess the value of CMV serology compared with the rapid detection of the virus in shell vial cell cultures or histology for the diagnosis of (1) the first evidence of infection, (2) symptomatic disease, and (3) asymptomatic infection. Of 28 evaluable patients, shell vial cell culture assay and histologic findings provided the first evidence of CMV infection earlier in 22 (79%) or at the same time as the serologic response in 5 (18%). Serologic results yielded the first indication of CMV infection in only 1 of these 28 patients (3%). Of 17 evaluable transplantations in 15 patients in whom symptomatic invasive disease developed, shell vial culture or histology provided a laboratory diagnosis of CMV infection earlier or at the same time as serologic responses in 16 (94%). Similarly, shell vial culture or histology provided evidence of CMV infection in 10 of 11 patients (91%) who had asymptomatic CMV infection and remained asymptomatic. Urine surveillance cultures yielded the first evidence of CMV infection in 14 of 19 patients who initially had an asymptomatic infection, of which 6 became symptomatic. Culturing of the blood with use of the rapid shell vial technique showed that viremia preceded CMV organ involvement in 7 of 10 patients. We recommend culture by the shell vial assay as the most rapid and sensitive method of determining CMV infection in liver transplant patients.
