Abstract
Objectives
To evaluate the prognostic ability of serum ferritin when estimated within 5 days of onset of illness in children with severe sepsis admitted to a pediatric intensive care unit.
Methods
This observational study enrolled children aged 1 month to 12 years with severe sepsis. Hemoglobin, serum ferritin and C-reactive protein levels were measured within five days of illness. Final outcomes were recorded in all enrolled children.
Results
70 children with median (IQR) age of 27 (8,108) months were enrolled during the study period (July, 2019 to August, 2021). 28 (40%) of these had poor outcome (nonsurvival). The median (IQR) level of serum ferritin was 1369 (558–5607) ng/mL in non-survivors and 282 (129–680) ng/mL in survivors (P<0.05). A significant correlation was seen between serum ferritin and Pediatric Risk of Mortality III (PRISM III) score (r=0.364 P=0.002) and pediatric Sequential Organ Failure Assessment (pSOFA) score (r=0.246 P=0.04) at 48 hours of admission. 54 (77.1%) children were anemic. Serum ferritin levels in children with anemia also had a good predictive ability for poor outcome [AUC: 0.764, 95% CI: 0.634, 0.894].
Conclusions
Serum ferritin levels, within five days of onset of illness, predicted poor outcome in critically ill children with severe sepsis and in children with microcytic anemia.
