Conditions such as HLH, MAS, sepsis, and MIS-C share similarities in clinical and laboratory aspects, including elevated ferritin levels. Therefore, in pediatric emergency settings, high ferritin levels accompanied by fever should prompt consideration of these rare syndromes for timely therapy.
Ferritin plays an important role in modulating inflammation and is a significant marker in some life-threatening pathological conditions. Hemophagocytic lymphohistiocytosis (HLH), macrophage activation syndrome (MAS), sepsis, and the more recent multisystem inflammatory syndrome in children (MIS-C) share many clinical and laboratory aspects, including the increase in ferritin levels, so that they are considered hyperferritinemic syndromes. In the pediatric emergency setting, the finding of high ferritin levels if associated with fever requires considering these rare syndromes to start a timely therapy.
