Abstract
Objective. We aimed to evaluate the diagnostic value of C-reactive protein (CRP) and α1-acid glycoprotein (α1AG) in the early diagnosis of neonatal sepsis.
Design. The study was prospectively conducted among newborns hospitalized for ‘rule out sepsis’ to neonatal intensive care unit (NICU).
Setting and subjects. A total of 97 children [16 with confirmed sepsis (Group I), 34 with clinical sepsis (Group II), and 47 in control group (Group III)] were enrolled in the study. On admission to NICU, blood was sampled for CRP, blood culture, and α1AG before starting antibiotherapy. Twenty-four hours later CRP and α1AG levels were detected for second tests in the study group.
Results. In Group I and II, while the 1st and 2nd tests CRP levels were not different, the 2nd test α1AG levels were significantly higher than the 1st test results (p < 0.01). Second test CRP and α1AG levels were also statistically higher in Group I than Group II (p < 0.05).
Conclusion. It is shown that CRP has limited value in the early diagnosis of neonatal sepsis. A significant increase in α1AG levels was detected in neonatal sepsis but its high specificity was accompanied with low sensitivity. Since the 2nd test α1AG values resulted with high sensitivity, we suggest that serial α1AG tests may be used but a single test for α1AG has limited usefulness in the neonatal sepsis which requires rapid diagnosis.
