Acute Urticaria

Jonathan S Tam
Hypersensitivity reactions to foods can have diverse and highly variable manifestations. Cutaneous reactions, such as acute urticaria and angioedema, are among the most common manifestations of food allergy. However, cutaneous manifestations of food allergy encompass more than just IgE-mediated processes and include atopic dermatitis, contact dermatitis, and even dermatitis herpetiformis. These cutaneous manifestations provide an opportunity to better understand the diversity of adverse immunologic responses to food and the interconnected pathways that produce them...

Differential diagnosis of urticaria and angioedema has been based on the phenotype as either acute or chronic depending on the duration of more than 6 to 8 weeks, respectively. Additional subdivisions include poorly defined terms such as idiopathic, spontaneous, or autoimmune. In this article, the author suggests that an increased understanding of the acquired and innate immune system and data from novel proteomic technology have blurred the lines between these categories of diagnosis. Specific molecular pathways and response to specific medications should be incorporated in classification and diagnosis schemes...

BACKGROUND: Lower serum vitamin B12 concentrations have been observed in patients with chronic spontaneous urticaria (CSU). It is known that vitamin B12 deficiency is closely related to hyperhomocysteinaemia, which is associated with a proinflammatory state. AIM: To assess the relationship between vitamin B12 status and concentrations of homocysteine (Hcy) with acute phase response in patients with CSU. METHODS: Circulating concentrations of vitamin B12, Hcy and C-reactive protein (CRP) were measured in 42 patients with CSU of varying severity, and compared with 19 healthy controls (HCs)...

Systemic hypersensitivity (HS) to corticosteroids (CS) is paradoxical but does exist. Some patients with a previous contact allergy to topical CS may develop a systemic contact dermatitis (SCD) while receiving CS orally or intravenously. However, a previous contact sensitization is not mandatory for developing a systemic HS to CS. Acute or delayed urticaria can occur in immediate HS. Immediate HS can be due to excipients, mainly carboxymethylcellulose or to CS themselves. Delayed reactions, mainly maculopapular rash and acute generalized exanthematous pustulosis can occur...

BACKGROUND: Hypersensitivity to acetylsalicylic acid (ASA) constitutes a serious problem for subjects with coronary artery disease. In such subjects, physicians have to choose the more appropriate procedure between challenge and desensitization. As the literature on this issue is sparse, the present study aims to establish in these subjects clinical criteria for eligibility for an ASA challenge and/or desensitization. METHODS: Collection and analysis of data on ASA challenges and desensitizations from 10 allergy centers, as well as consensus among the related physicians and an expert panel...

The acute clinical symptoms that develop following the oral ingestion of aspirin, or any other inhibitor of cyclooxygenase-1, are well established in aspirin-exacerbated respiratory disease: nasal congestion, rhinorrhea, and bronchospasm. Less commonly, gastrointestinal distress, rash, angioedema, or urticaria also develops. However, the pathobiology that drives these clinical reactions is poorly understood. Use of an intranasal aspirin challenge protocol or administration of premedications inhibiting the leukotriene pathway decreases the severity of clinical reaction, which suggests the involvement of both local effector cells and cysteinyl leukotrienes in the pathogenesis of aspirin-induced reactions...

Urticaria is a common skin condition that can compromise quality of life and may affect individual performance at work or school. Remission is common in majority of patients with acute spontaneous urticaria (ASU); however, in chronic cases, less than 50% had remission. Angioedema either alone or with urticaria is associated with a much lower remission rate. Proper investigation and treatment is thus required. This guideline, a joint development of the Dermatological Society of Thailand, the Allergy, Asthma, and Immunology Association of Thailand and the Pediatric Dermatological Society of Thailand, is graded and recommended based on published evidence and expert opinion...

Urticaria is a common skin disorder defined by the occurrence of itchy and even painful wheals, angioedema, or both. The lifetime prevalence for its acute and chronic form is 20 and 1%, respectively. The patients' quality of life is impaired because of itch, disfigurement, and high associated comorbidity. To understand the pathophysiology of the wheal in order to ensure a correct therapeutic approach is critical. Mast cells are the primary effector cells in urticaria, which produce and secrete a variety of inflammatory mediators, mainly histamine...

Blastocystis spp. are widely prevalent extra cellular, non-motile anerobic protists that inhabit the gastrointestinal tract. Although Blastocystis spp. have been associated with gastrointestinal symptoms, irritable bowel syndrome and urticaria, their clinical significance has remained controversial. We established an ex vivo mouse explant model to characterize adhesion in the context of tissue architecture and presence of the mucin layer. Using confocal microscopy with tissue whole mounts and two axenic isolates of Blastocystis spp...

BACKGROUND: Acute urticaria is an immune-inflammatory disease, characterised by acute immune activation. There has been increasing evidence showing that vitamin D deficiency is associated with increased incidence and severity of immune-inflammatory disorders. OBJECTIVE: The aim of this study was to evaluate serum vitamin D levels in acute urticaria. METHODS: We enrolled 30 children with acute urticaria and 30 control subjects. Concentrations of 25-hydroxyvitamin D [25(OH)D], a biomarker of vitamin D status, were measured in serum of acute urticaria patients and compared with the control group...

BACKGROUND: Kawasaki disease (KD) is an acute, systemic vasculitis in children, with an etiology that is not completely understood. It is assumed that the development of KD is mediated by an immunologic response. Several reports from East Asia have found a higher prevalence of atopic diseases among patients with KD, but a large-scale study of a non-Asian population regarding this correlation is still lacking. The purpose of this article was to achieve this goal. METHODS: We conducted a cross-sectional, large-scale study to estimate the correlation of KD with allergic diseases...

BACKGROUND: Therapeutic options for pain management are restricted in patients with nonsteroidal anti-inflammatory drug (NSAID)-induced or NSAID-exacerbated urticaria because strong cyclooxygenase (COX)-I inhibiting NSAID cannot be used. Alternative NSAID such as weak COX-I inhibitors or selective COX-II inhibitors are sometimes not sufficiently effective or have potentially troublesome adverse effects. OBJECTIVE: To date, prophylactic premedication with H1-antihistamines is rarely practiced in patients concurrently suffering from recurrent pain and NSAID-associated urticaria...

INTRODUCTION: Dicobalt edetate is one of a number of cobalt compounds that have been studied in the treatment of cyanide poisoning, their efficacy being based upon the fact that cyanide combines with cobalt to form relatively non-toxic complexes. Inorganic cobalt salts are quite toxic (cyanide and cobalt antagonise one another's toxicity) and complexes such as dicobalt edetate were studied with the aim of identifying compounds that were less acutely toxic, but which retained the antidotal properties of cobalt salts...

BACKGROUND: Asthma and urticaria are both partially mediated by an increased release of histamine from highly activated mast cells. They are pathophysiologically different, as mast cell degranulation in these 2 disorders results from different mechanisms. OBJECTIVE: To assess the incidence of urticaria in patients with asthma, and of asthma in patients with chronic spontaneous urticaria (CSU). PATIENTS AND METHODS: Over 1 year of follow-up, asthma patients (n = 110) were assessed for the incidence and characteristics of urticaria, and a link, if it existed, to seasonal exacerbations and the severity of asthma was traced...
