Background: Adequate study of allergic fungal rhinosinusitis (AFRS) helped better understanding of the nature of the disease. It involves immediate hypersensitivity to fungus present in the nose and sinuses. This involves immunoglobulin E. Therefore the presence of serum IgE indicates the presence of the allergic reaction.The objective is to evaluate the relationship between systemic steroid therapy and the level of serum IgE in allergic fungal rhinosinusitis indicating adequate therapy. This is a prospective study.
Subjects and Methods: Forty patients diagnosed as allergic fungal sinusitis were randomly divided into two equal groups: group A was given postoperative systemic steroids and local steroids, while group B was not given systemic steroids (local steroids only). The patients were followed up for three and six months by testing IgE levels in blood.
Results: The total number of patients who had more than 10% increase in serum IgE after 6 months post-operative was 18 patients. Six of them were from group A (Systemic steroids) and 12 were from group B (Local steroids).
Conclusion: There was a strong relation between systemic steroid therapy and the level of serum IgE. Thus, AFS should be treated by systemic steroids for a prolonged period after adequate clearance of the sinuses. Patients should be followed up at close intervals post-operative using serum Ig E as it can indicate increased fungal load and the need for further treatment.
