Different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis. Objective: To investigate association of haptoglobin (Hp) phenotypes (Hp1-1, 2-1 and 2-2) with serum immunoglobulins A and E levels in patients suffering from AR in comparison with healthy individuals. Methods: Two hundred and forty patients and 240 healthy individual entered in this case-control study. Serum levels of IgE and IgA were measured and haptoglobulin phenotypes were determined by electrophoresis. The results were evaluated by χ2 statistical test using SPSS software. Results: Serum electrophoresis showed that the distribution of haptoglobin phenotypes of Hp1-1, Hp2-1 and Hp2-2 among 240 patients were 11.3%, 37.9% and 50.8%, respectively. The distribution of different haptoglobin phenotypes in healthy controls were 88.7%, 36.6% and 54.7%, respectively. However, the difference between patients and controls was not statistically significant (p=0.136). The mean of IgE level was significantly higher in patients than controls in association with all three phenotypes (p<0.001). Mean of IgA serum level was also significantly different between case and control groups for Hp1-1 (p<0.048) and Hp2-2 phenotypes (p<0.027). Conclusion: We conclude that there is an association of all three haptoglobin phenotypes with IgE level. Hp1-1 and Hp2-2 phenotypes showed association with IgA in allergic rhinitis, as well. However, we cannot solely attribute these associations to the pathogenesis of allergic rhinitis.}, keywords = {Allergic Rhinitis,Haptoglobin,IgA,IgE}, url = {https://iji.sums.ac.ir/article_16879.html}, eprint = {https://iji.sums.ac.ir/article_16879_f0421496eb677568a77afab2872a4cc2.pdf} }
