Objective: To determine the prevalence of antibody to hepatitis C viru
s (HCV) in a cohort of neonates who received extracorporeal membrane o
xygenation (ECMO) therapy, and to determine risk factors associated wi
th seropositivity. Design: Eighty-three patients who had been treated
with ECMO as neonates (from August 1986 through January 1992) at Child
ren's Hospital, Boston, were tested for antibodies to HCV. The medical
records were reviewed, and information regarding neonatal history was
obtained. Anti-HCV seronegative and seropositive children were compar
ed using univariate and multivariate analyses. Results: Seven patients
(8%) were anti-HCV seropositive. Of the seven seropositive children,
four (57%) currently have ALT values of more than 1.5 times the upper
limit of normal; only five of the 52 (9.6%) seronegative patients have
values this high (P < .001). Patients in the seropositive group had r
eceived blood screened by ''surrogate markers'' (6 of 50) or by ELISA-
1 anti-HCV testing (1 of 33). Significant differences between the sero
positive and seronegative patients were found with respect to the amin
otransferase and bilirubin levels during the initial ECMO hospitalizat
ion. The last ALT value before discharge was the only significant pred
ictor of HCV infection in the multivariate model. Conclusion: Neonates
treated with ECMO are at risk for the development of HCV infection. N
eonates who received blood products from donors screened by surrogate
markers or ELISA-1 anti-HCV testing should be considered at risk. Neon
ates who had an abnormal ALT value at the time of discharge are most l
ikely to be anti-HCV seropositive. (C) 1996 by W.B. Saunders Company
