Abstract |
Purpose : The early and efficient diagnosis of neonatal sepsis still remains a difficult task.
Reliable laboratory test is not available yet and treatment is mainly based on the physical
appearance of infants. And high number of negative blood cultures in cases of clinically
diagnosed sepsis further emphasize the need for a more reliable index for early diagnosis.
Intercellular adhesion molecule 1(ICAM-1) has been known important in various immunological
processes early in inflammation, and recently circulating ICAM-1 (cICAM-1) has been detected
in serum and supernatant of cytokine-activated endothelial cell cultures. The purpose of our
study was to evaluate cICAM-1 as a marker in neonatal sepsis.
Methods : Using enzyme linked immunosorbent assay(ELISA), we measured serial
cICAM-1 over the first week of admission in 48 neonates who were admitted at NICU
due to clinically suspected sepsis.
Results : We found the levels of cICAM-1 on admission in 9 culture proven and 20 clinically
dignosed septic neonates(1723.3¡¾669.7ng/ml and 994.9¡¾358.5ng/ml, respectively) were
significantly higher(P < 0.001) than those in neonates showing systemic inflammatory signs
without evidence of sepsis and healthy controls(380.6¡¾235.8ng/ml and 238.8¡¾96.6ng/ml,
respectively). The cICAM-1 levels on admission in septic neonates with high severity score
were higher than those with low severity score(P < 0.01). Fatal cases exhibited higher cICAM-1
on admision than did survivals(1710.8¡¾634.5ng/ml versus 963.4¡¾411.4ng/ml, P < 0.0001) and
there seemed to be a positive correlation between cICAM-1 levels and mortality. The elevation
of cICAM-1 on admission in septic neonates appeared earlier than the rise of c-reactive
protein(CRP) above 10mg/L.
Conclusions : The measurement of cICAM-1 on admisson might be useful for the
early detection of neonatal sepsis and high cICAM-1 level suggests poor prognosis. |
