Evaluation of children with steroid-sensitive nephrotic syndrome in terms of allergies

Abstract

Background: The etiology of minimal-change disease is not fully known, it is believed to be mediated by the immune system. Minimal-change disease also reported as having association with atopy. In this study, atopy history, the levels of serum IgE, and skin prick test in children with steroid-sensitive nephrotic syndrome were investigated. Methods: A group of 30 children (mean age 7.7 ± 2.2 years, 56.6% male) diagnosed with steroid-sensitive nephrotic syndrome were included in the study. Serum immunoglobulin E levels and eosinophil counts were evaluated in children with steroid-sensitive nephrotic syndrome both in relapse and remission. Skin prick test was performed in remission. Results: Of the 30 children investigated, 11 (36.7%) had a history of atopy. The median serum total IgE levels in nephrotic children in relapse, with (445 IU/mL) and without atopy (310 IU/mL) were significantly higher than those in remission (respectively, 200 IU/mL, p = 0.021, and 42 IU/mL, p = 0.001). The skin prick tests for all the allergens were evaluated as negative in all the patients. Conclusion: It was thought that increased IgE may reflect the activation of immune mechanism following various stimuli rather than a direct association with atopy in children with steroid-sensitive nephrotic syndrome.
