Abstract |
Purpose : The aims of present study were to document the incidence of cytomegalovirus
infection in neonatal and infantile periods especially in high-risk patients of associated infection
by nested PCR of DNA from leukocytes and to evaluate the effectiveness of nested PCR in the
diagnosis of congenital cytomegalovirus infection.
Methods : Genomic DNA was extracted from peripheral leukocytes of 204 neonates and infants
during the period from June 1994 to March 1995, and nested PCR was performed. The cases
were divided into six groups according to clinical profiles; Group IA-healthy fullterm babies,
group IB-fullterm babies with suspected or definite perinatal infection, group IIA-healthy preterm
babies, group IIB-preterm babies with suspected or definite perinatal infection, group III-infants
with clinical features of viral infection and abnormal liver function tests, group IV-IgM
seropositive babies with clinical evidence of cytomegalovirus infection.
Results : In group ⅠA(n=70), 2 cases were positive for PCR amplification (2.9%). All of the
cases in group ⅠB(n=64), group ⅡA(n=15), and group ⅡB(n=20) were negative for cytomegalovirus
infection. Only one case(3.3%) among group Ⅲ(n=30) showed positive reaction, while
all of the five cases(100%) in group Ⅳ(n=5) were positive.
Conclusion : The incidence of congenital cytomegalovirus infection in our analysis were 1.2%
(2/169), and it was similar to that of western countries. Nested PCR was proved to be a both
sensitive and specific diagnostic tool in the diagnosis of cytomegalovirus infection and it seems
to be useful in the screening of congenital cytomegaloviral infection in the newborn period.
Future analysis of samples including non-blood origin from adult women and newborns will be
helpful in the epidemiologic analysis of cytomegalovius infection in this period. |
