Purpose of reviewEighty to 90% of patients with chronic urticaria have no specific external cause for their disease, which is therefore labeled ‘chronic idiopathic urticaria’. We now know, however, that as many as 30–50% of patients have evidence of an autoantibody to the high-affinity receptor for IgE (FcϵRI), which may be pathogenic. The exact prevalence and role of these autoantibodies is still under investigation. Recent findingsThe frequency of autoantibodies to FcϵRI in chronic urticaria… Expand

New concepts in chronic urticaria.
TLDR
The presence of serum IgG autoantibodies targeting IgE or the IgE receptor in approximately 40% of CIU cases supports the theory of an autoimmune basis for the disease, however, issues remain with the assays to detect autoantIBodies among other serum factors, the relationship of autoant ibodies to CIU disease activity, and the occurrence of autoantsibodies in healthy subjects. Expand
Chronic autoimmune urticaria as the presenting manifestation of primary hyperparathyroidism.
TLDR
The case of a parathyroid adenoma is presented in a patient with the initial presentation of urticaria with antibody testing positivity consistent with CAU, and it is hypothesized that the elevated IgE levels lead to mast cell and basophil activation and degranulation, with resultant histamine release. Expand
An Update on Acute and Chronic Urticaria for the Primary Care Provider
TLDR
Evidence suggests that up to 30% to 50% of idiopathic cases may be autoimmune and/or related to mast cell/basophil abnormalities and there is further evidence of an autoantibody to the high-affinity receptor for IgE, specifically binding to the α-chain (FcϵRIα), which may be pathogenic. Expand

TLDR
Patients with CIU with a basophil responder phenotype report longer disease duration, a higher frequency of emergency department use, and significantly higher itch severity, and quality-of-life impairment is similar in CIU basophils subsets. Expand
Chronic urticaria and autoimmune thyroiditis.
TLDR
This significant association between chronic urticaria and autoimmune thyroiditis is higher than the incidence of auto-immune thyroiditis in the general population and may change the medical practice in Lebanon by including anti-TPO and anti-thyroglobulin antibodies in the workup of patients with chronic urtics. Expand
Serum induced CD63 and CD203c activation tests in chronic urticaria
TLDR
A positive correlation between CD63 assay and ASST indicates the potential usefulness of this test for the diagnosis of the autoimmune form of CU, and serum from CU patients upregulated both CD63 and CD203c molecules on blood basophils. Expand
Basophil responsiveness in chronic urticaria

  • 2009
TLDR
In active chronic idiopathic urticaria (CIU) subjects, changes in IgE receptor-signaling molecule expression levels accompany the altered degranulation function in blood basophils, and the arrival of therapies targeting IgE has shown that alteredBlood basophil de granulation behavior has potential use as a disease biomarker in CIU. Expand
Recurrence of Chronic Urticaria: Incidence and Associated Factors.
TLDR
Alternative agent use and antihistamine refractoriness appear to place patients at increased risk for recurrence compared with first-line agent use alone. Expand
Treatment of autoimmune urticaria with low-dose cyclosporin A: A one-year follow-up.
TLDR
Cyclosporin A, even in low-doses, can be an effective and short-term treat- ment with minimum side-effects in patients with AIU. Expand
The autologous serum skin test in a cohort of chronic idiopathic urticaria patients compared to respiratory allergy patients and healthy individuals
TLDR
The ASST is regarded as a reliable in vivo test in chronic idiopathic urticaria patients, with diagnostic, therapeutic and prognostic implications, however, positive ASST results have also occasionally been demonstrated in patients with other diseases and in healthy subjects. Expand

Assessment of autoimmunity in patients with chronic urticaria.
TLDR
A large fraction of patients with chronic urticaria have antibody directed to Fc epsilon RI alpha that is functional and a smaller number have IgG anti-IgE (10%) and a third group may also have circulating factors capable of activating basophils or mast cells of which the identity is unknown. Expand
Mechanisms of autoimmune activation of basophils in chronic urticaria.
TLDR
A subpopulation of patients with chronic urticaria possess IgG antibody directed to the alpha subunit of FcepsilonRI, which activates basophils, which is dependent on or augmented by complement, and binding assays for this IgG are not currently feasible as a screening method. Expand
Comparative studies of functional and binding assays for IgG anti-FcϵRIα (α-subunit) in chronic urticaria ☆ ☆☆ ★ ★★
TLDR
It is suggested that approximately 45% to 50% of patients with chronic urticaria have a cutaneous autoimmune disorder and immunoblotting may provide a rapid screening method for anti-Fc ϵ RI α detection in such patients. Expand
Functional assessment of pathogenic IgG subclasses in chronic autoimmune urticaria.
TLDR
Purification of IgG subclasses from patients with chronic urticaria demonstrates functional antibody in IgG 1 and IgG 3 and occasionally IgG 4 . Expand
Evidence of in vivo basophil activation in chronic idiopathic urticaria.
TLDR
Basophil activation marker expression is increased in CIU subjects and is not associated with serum factors, while serum HRA and FcepsilonRIalpha immunoreactivity are not unique to CIU, or related to enhanced circulating basophil marker expression. Expand
The autologous serum skin test: a screening test for autoantibodies in chronic idiopathic urticaria
TLDR
The parameters of the ASST are determined which define the optimal sensitivity and specificity for the identification of patients with autoantibodies and the following subjects had positive ASSTs: none of 15 dermographics, none of 10 atopics, one of nine cholinergics and one of 40 controls. Expand

TLDR
Suggested therapy for patients with severe disease involves the use of high-dose hydroxyzine or diphenhydramine when nonsedating antihistamines are ineffective, supplemented by H-2 antagonists and leukotriene antagonists. Expand
Autoantibodies against the high-affinity IgE receptor as a cause of histamine release in chronic urticaria.
TLDR
Histamine-releasing IgG autoantibodies against the alpha subunit of the high-affinity IgE receptor are present in the circulation of some patients with chronic urticaria. Expand
Complement dependence of histamine release in chronic urticaria.
TLDR
The degranulation of mast cells by IgG autoantibodies in patients with chronic urticaria requires binding to the IgE receptor and activation of the classical complement cascade. Expand
Anti-FcϵRI autoantibodies and basophil histamine releasability in chronic idiopathic urticaria☆☆☆★★★♢
TLDR
Patients with autoantibodies have both markedly reduced basophil numbers and basophIL histamine release to factors acting through FcϵRI, which indicates either a residual pool of functionally distinct basophils or may be a consequence of desensitization of the Fc ϵRI pathway. Expand
