Abstract
BOZLU, Gulcin; TANRIVERDI, Huseyin; ASLAN, Gonul and KUYUCU, Necdet. The value of acute phase reactants and LightCycler® SeptiFast test in the diagnosis of bacterial and viral infections in pediatric patients. Arch. argent. pediatr. [online]. 2018, vol.116, n.1, pp.35-41. ISSN 0325-0075. http://dx.doi.org/10.5546/aap.2018.35.
Introduction: This study was performed to investigate the value of acute phase reactants and LightCycler® SeptiFast test to differentiate bacterial and viral infections. Population and methods: Children with fever were enrolled to this prospective study. Peripheral white blood cell (WBC), C-reactive protein (CRP) and procalcitonin (PCT) were studied from all patients on day 1, 3 and 7. Blood culture and chest X-ray were also obtained on day 1. Blood samples for LightCycler® SeptiFast test were obtained in all patients to use them if there was uncertain diagnosis between bacterial or viral infection. The patients were divided into two groups as bacterial and viral infection. Results: A total of 94 children with fever were enrolled. The mean value of fever was significantly higher in bacterial group than viral group (p <0.001). In bacterial infection group, 34 (72.3%) patients had negative blood culture. Of those, 12 (35.2%) had positive SeptiFast test. There were no positive blood culture in patients with viral infection group and all of them had negative SeptiFast test. The mean levels of CRP on the first day of admission were significantly higher in bacterial group than viral group (p <0.001). CRP and PCT levels of day 3 and 7 were significantly higher in bacterial group (p <0.001). The sensitivity and specificity levels of WBC, CRP and PCT were 63.8%, 44.7%, 74.5% and 78.7% ,68.1% and 100%, respectively. Conclusions: We found that acute phase reactants, especially PCT, and LightCycler® SeptiFast test may help to differentiate bacterial and viral infections.
