Ensina LF, Brandão L, Arruda LK, Sarquis Serpa F, Campos RA, Valle SRO, Criado PR, Saini SS, Criado RFJ. IgE as a predictor to omalizumab response in patients with chronic spontaneous urticaria. FRONTIERS IN ALLERGY 2025; 5:1451296. [PMID: 39917427 PMCID: PMC11798913 DOI: 10.3389/falgy.2024.1451296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Accepted: 12/16/2024] [Indexed: 02/09/2025] Open
Abstract
This multicenter study aimed to explore whether baseline total immunoglobulin E (IgE) levels could predict omalizumab response in chronic spontaneous urticaria (CSU) patients. Refractory CSU patients, treated with omalizumab after failing second-generation H1-antihistamines, were analyzed retrospectively across seven centers in Brazil. The study assessed total IgE levels at baseline, comparing responders to non-responders and considering complete and partial responses. The results showed a significant reduction in CSU symptoms post-treatment. Non-responders had lower baseline IgE levels. A sensitivity of 67.8% and specificity of 93.3% for predicting a response were found at an IgE level of 59.5 IU/ml. Similar values were observed for complete responders. Notably, a baseline IgE level lower than 59.5 IU/ml may indicate late responders. The study underscores the potential of baseline IgE levels as a predictive biomarker for omalizumab response in CSU patients. Further research, incorporating diverse populations and analyzing response variables, is warranted to validate these findings.

The Evolution of Emergency Urticaria Cases Before and During the SARS-CoV-2 Pandemic. ARS MEDICA TOMITANA 2022.

Abstract
Abstract
Urticaria is one of the best-known dermatological diseases and affects between 15% and 25% of the global population. Angioedema, an acute complication of urticaria, affects about 3% of the population.
The retrospective study took into account the patients diagnosed with urticaria in the emergency room of the Măcin City Hospital, and aimed to assess the epidemiological aspects during the 2015-2020 period, and too see how it the SARS-CoV-2 pandemic influenced the incidence of diagnosed urticaria in the emergency room of a local hospital from South-East Romania.
The impact of SARS-CoV-2 pandemic might be observed in the ER activity of city hospitals, where a decreased number of presentations was observed, and, at the same time with an increase in the proportion and absolute number of urticaria cases.
