Coexistence of Allergic Diseases in Pediatric Systemic Lupus Erythematosus Patients: Prevalence, Clinical manifestation and Severity

Abstract

Objective. This study aimed to evaluate allergic diseases in pediatric patients with SLE and their association with SLE disease activity. Method. Patients with SLE aged ≤18 years were enrolled. Allergic diseases were screened using the International Study of Asthma and Allergies in Childhood questionnaire. Patients with a positive allergic disease screen were evaluated by a pediatric allergist for diagnostic confirmation and severity assessment. Results. Out of 118 patients, 16 patients (13.56%) were confirmed to have 1 or more allergic diseases; fourteen with allergic rhinitis, 4 with asthma, and 2 with atopic dermatitis. Two patients had severe-persistent allergic rhinitis and one patient had undiagnosed, uncontrolled severe asthma. No statistically significant correlations between the severity of allergic diseases and SLE disease activity were identified. Conclusions. The overall prevalence of allergic disease among pediatric patients with SLE is within the range of the general population. Severe and undiagnosed allergic diseases and SLE can coexist.
