Abstract
Globally, sepsis is the primary cause of death for children. While research conducted on adults has a significant impact on the diagnosis and treatment of sepsis in newborns and young children, there are significant factors that are pertinent to pediatrics as well. This prospective case-control study was conducted during the period from August 2020 to October 2022 after approval by the institutional ethical committee. The study included 48 critically ill children admitted at the Pediatric intensive care unit and 30 apparently healthy children as a control group. Laboratory investigations including complete blood picture, C-reactive protein (CRP), blood culture and sensitivity and plasma level of cluster of differentiation 64 (CD64) and myeloperoxidase (MPO) were investigated for all participants. A daily follow up for the signs of systemic inflammatory response syndrome (SIRS) or sepsis was done, and the patients were divided into SIRS and non-SIRS subgroups then patients were divided into two groups according to the presence of severe sepsis. A follow up CD64 and MPO sample were withdrawn from them to assess their prognostic value. SIRS was reported in 39.58 % of patients while severe sepsis was reported in 20.8%. CD64 and MPO were significantly higher in cases than controls (p= 0.003, p<0.001, respectively) and, in patients with SIRs and severe sepsis CD64 was 1559.00± 367.09 pg/ml and 1547.9 4± 436.14 pg/ml, respectively. Also, MPO was significantly higher in patients with SIRS (113.58± 25.19 mU/ml) and severe sepsis (111.70± 26.50 mU/ml). CD64 and MPO significantly increased after development of sepsis in admitted patients. ROC was significantly higher for CD64 and MPO at admission than that for CRP at admission (p=0.123, p=0.014, respectively). In conclusion, plasma level of CD64 and MPO in peripheral blood can be considered an early sensitive marker for the detection and follow up of pediatric sepsis.
