Abstract Psoriasis is a chronic relapsing disorder that involves the skin, nails and joints. With regard to the role of the immune system in psoriasis, the current study compared serum IgE concentration in patients with psoriasis with control group. Current case-control study was conducted in Dermatology clinic of Razi hospital, Tehran University of medical sciences, Tehran, Iran in 2012. Fifty-eight patients with psoriasis e referred to the clinic were assigned as patient group and 58 healthy subjects with matched age and sex as a control group. Patient's history, family history and demographic characteristics such as age and sex, duration and severity of disease using PASI, were collected and entered into a form. Consent form was obtained from participants. Serum IgE concentrations of both study groups were measured by electrochemiluminescence assay in the laboratory A total number of 58 patients with psoriasis, mean age of 44.15 (19-76 years) and 58 controls with matched age and sex were studied. Mean average of serum IgE concentration in the control group was 115.13 versus 200/06 concentration in patients group (P=0.16). Serum IgE concentration in 22.4\% of patients versus 17.2\% in controls was greater than normal concentration (P=0.48). No significant correlation was between serum IgE concentration and disease severity using PASI (P=0.11, r=0.21), neither a significant correlation with disease duration, age and gender. According to the present study, serum IgE concentrations are not greater in patients with psoriasis. IgE concentration is also not associated with the severity of psoriasis based on the PASI score, therefore, the role of IgE in psoriasis can be considered insignificant as some previous studies indicate.
