BACKGROUND: Despite improved understanding of the pathophysiology of allergic rhinitis and asthma, the effect of serum leptin level is still controversial. Only a few studies have been performed to investigate the serum leptin levels in allergic rhinitis and asthma, and contradictory results have been observed. OBJECTIVE: We aimed to investigate the association between leptin, lipid profiles and allergic rhinitis and mild asthma, and to determine whether inhaled and/or intranasal steroids affect the leptin levels. PATIENTS AND METHODS: We studied 43 patients with allergic rhinitis (10 of with mild asthma) (mean age 29.81, range 18-45 yr) and 32 volunteers as a control group (mean age 30.53, range 20-45 yr). RESULTS: Serum leptin levels in patients were 8.49 +/- 10.76 microg/ml, and did not differ from volunteers 5.42 +/- 6.63 microg/ml. (p > 0.05). We found a direct link between increased body mass index (BMI) and serum leptin levels (p = 0.008). No association was seen between leptin and triglyceride, HDL-cholesterol, VLDL-cholesterol, eosinophil, total IgE (p > 0.05); except for total cholesterol and LDL-cholesterol (p < 0.05). Although, no correlation between allergic rhinitis and mild asthma and serum level of leptin was shown, these parameters and age correlations were stronger in female than in male (p = 0.39 for male and p = 0.011 for female), and also found direct link between increased BMI and sex and patients group (p = 0.008 for male and p = 0.0001 for female). We also determined that there was no effect of inhaled and/or intranasal steroids statistically on serum leptin levels. CONCLUSION: Our data demonstrate that the serum levels of leptin and lipid profiles on allergic rhinitis and mild asthma were not different than those in controls.
