Serum Iron and Haemoglobin Estimation in Oral Submucous Fibrosis and Iron Deficiency Anaemia: A Diagnostic Approach

摘要

Introduction: Oral Submucous Fibrosis (OSMF) is a premalignant condition with potential malignant behaviour characterized by juxta-epithelial fibrosis of the oral cavity. In the process of collagen synthesis, iron gets utilized, by the hydroxylation of proline and lysine, leading to decreased serum iron levels. The trace element like iron is receiving much attention in the detection of oral cancer and precancerous condition like OSMF as it was found to be significantly altered in these conditions.Aim: The aim of this study was to compare the haemoglobin and serum iron values of OSMF subjects with that of iron deficiency anaemia subjects.Materials and Methods: Total of 120 subjects were included, 40 subjects with the OSMF, 40 with the iron deficiency anemia without tobacco chewing habit, 40 healthy control subjects without OSMF and iron deficiency anaemia. A total of 5ml of venous blood was withdrawn from all the subjects and serum iron and haemoglobin levels were estimated for all the subjects. Estimation of iron was done using Ferrozine method and haemoglobin by Sahli?s method. The statistical method applied were Kruskal Wallis, Mann Whitney and Pearson correlation coefficient test.Results: There was a statistically significant difference in serum iron and haemoglobin level in all three groups (p<0.05). The serum iron level was lowest in OSMF group and haemoglobin was lowest in iron deficiency anaemia group. A progressive decrease in serum iron and haemoglobin levels from Stage I of OSMF to the Stage IV of OSMF was also observed. The iron deficiency anaemia group was not found to be suffering from OSMF in the absence of areca-nut or tobacco chewing habits, but OSMF patients with chewing habits were found to be suffering from iron deficiency anaemia.Conclusion: There is a progressive decrease in serum iron and haemoglobin levels from Stage I of OSMF to the Stage IV of OSMF so it can be used as an auxillary test in assessment of prognosis of the disease.
