INTRODUCTION Chronic urticaria is characterized by recurring episodes of spontaneous transient dermal wheals and pruritus, with or without angioedema, which can persist for ≥ 6 weeks. Chronic urticaria impairs quality of life, emphasizing the need for effective treatments. Professional societies and clinical experts have issued evidence-based recommendations for the management of chronic urtica...

Urticaria involves intensely pruritic, raised wheals, with or without edema of the deeper cutis. It is usually a self-limited, benign reaction, but can be chronic. Rarely, it may represent serious systemic disease or a life-threatening allergic reaction. Urticaria has a lifetime prevalence of approximately 20 percent in the general population. It is caused by immunoglobulin E- and nonimmunoglob...

BACKGROUND IgE-independent (pseudoallergic) reactions to food and food ingredients are common in a subgroup of adult patients with chronic urticaria, who have daily spontaneous occurrence of wheals. However, for children with chronic urticaria (duration longer than 6 weeks, no physical influence), no data on the importance of pseudoallergen-induced chronic urticaria are available. Therefore, we...

BACKGROUND Vascular endothelial growth factor (VEGF) is a powerful enhancer of vascular permeability and inflammatory response; however its significance in chronic urticaria is poorly recognised. AIM To compare free circulating levels of VEGF and its soluble receptors (sVEGFR1 and VEGFR2) in patients with different forms of chronic urticaria. METHODS The concentrations of VEGF and its recep...

Schnitzler's syndrome is an unusual clinical association of chronic urticaria, intermittent fever and monoclonal immunoglobulin M (IgM) gammopathy. The pathogenesis of the urticaria is unclear and treatment is problematic. We describe the case of a 61-year-old woman with a long history of chronic urticaria with severe pruritus, spiking fever and malaise. The IgM-kappa monoclonal component was d...

BACKGROUND Chronic urticaria is a common skin condition that causes significant impact on patient's quality of life. OBJECTIVE The purpose of the study was to assess adherence to therapy and quality of life of patients with chronic urticaria. We also aimed to study the relationship of medication adherence and quality of life of patients with chronic urticaria. METHODS A cross sectional stud...

BACKGROUND Previous success rates of psoralen and ultraviolet A (PUVA) and narrowband UVB (NB-UVB) in the treatment of chronic urticaria are reported in few studies with no previous reports on the comparable efficacy of both modalities in the disease. AIM We aimed to compare the efficacy of PUVA versus NB-UVB in the treatment of chronic urticaria. METHODS Twenty-four patients with chronic u...

This guideline, together with its sister guideline on the management of urticaria [Zuberbier T, Asero R, Bindslev-Jensen C, Canonica GW, Church MK, Giménez-Arnau AM et al. EAACI/GA(2)LEN/EDF/WAO Guideline: Management of urticaria. Allergy, 2009; 64:1427-1443] is the result of a consensus reached during a panel discussion at the 3rd International Consensus Meeting on Urticaria, Urticaria 2008, a...

Background: Chronic urticaria is a long-lasting condition, sometimes with serious comorbidities, severely affecting the quality of life, which makes patients seek efficient therapies to achieve sustained remissions. The complex nature greatly complicates patients’ responses appropriate treatments. Objectives: This review was conducted focus on Janus kinase (JAK) pathway, evaluate its role as ne...
