Comparison of the Efficacy and Safety of Levocetirizine versus Bilastine for the Treatment of Chronic Spontaneous Urticaria in the Pediatric Population: An Observer-blinded Randomized Control Trial
Abstract
Abstract Background: Chronic spontaneous urticaria (CSU) refers to urticaria that has no specific cause or trigger, present on most days of the week for 6 weeks or more. The incidence of chronic urticaria in the pediatric age group is between 0.1% and 3%. Levocetirizine and bilastine are nonsedative second-generation antihistamines used to treat urticaria in both adults and children. Objective: The primary objective was to compare the effectiveness of levocetirizine and bilastine in cases of pediatric CSU using Urticaria Activity Score (UAS) and Urticaria Severity Score (USS). The secondary objective was to evaluate and compare the safety and quality of life (QoL) using the Dermatology Life Quality Index (DLQI) score. Materials and Methods: This was a randomized, observer-blinded study where 65 patients (6–16 years) with a history of urticaria >6 weeks were divided into two groups with computer-generated randomization. Thirty-two patients were included in Group A, who received levocetirizine, and 33 patients were included in Group B, who received bilastine. UAS7, USS, and DLQI were recorded at every visit. The primary outcome was measured using UAS and USS and the secondary outcome in the form of patient’s QoL was assessed using the DLQI score. Laboratory parameters were assessed at the first visit and at the end of 3 months. Results: There was a significant difference ( P = 0.002) in UAS7, USS, and DLQI between the baseline and last visit scores for each group. There was no…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 65 participants or records.
