Salivary ferritin as a predictive marker of iron deficiency anemia in children.
OBJECTIVE
The objective of the study was to determine the salivary Ferritin levels in children with iron deficiency anemia and its reliability as a predictive marker of the disease and whether these levels could give a new hypothetical insight on the oral epithelial changes seen in patients with iron deficiency anemia.


METHODS
The study comprised of 60 children of which the study group comprised of 30 individuals; aged 8-14 years with iron deficiency anemia. Venous blood was collected and hematological examination was performed to determine the hemoglobin and serum ferritin levels to confirm the diagnosis. Saliva was then collected from 30 children with iron deficiency anemia and an equal number of controls. The ferritin levels in saliva were then analyzed using solid phase ELISA.


RESULTS
The mean value of salivary ferritin in iron deficient cases was 153.24 +/- 46.58 microg/dl and the mean ferritin levels in control subject were 93.87 +/- 30.15 microg/dl. Thus the salivary ferritin was found to be significantly higher in iron deficient subjects compared to the controls.


CONCLUSIONS
The result of our research affirms the fact that the expression of ferritin in saliva of iron deficiency anemia may be due to the enzymatic functions in the saliva and the endocytosis of ferritin which can possibly elevate the salivary ferritin. The diminished level of cytochrome oxidase, together with its relatively high Ferritin content, depicts the association of oral epithelial changes and ferritin occurring in iron deficiency anemia.
