Abstract
Importance Omalizumab is indicated for the management of chronic idiopathic urticaria (CIU) (also known as chronic spontaneous urticaria) in adolescents and adults with persistent hives not controlled with antihistamines. The effectiveness of omalizumab in the real-world management of CIU is largely unknown. Objective To quantitatively synthesize what is known about the benefits and harms of omalizumab in the real-world clinical management of CIU regarding urticaria activity, treatment response, and adverse events. Data Sources Published observational studies (January 1, 2006, to January 1, 2018) and scientific abstracts on the effectiveness of omalizumab in CIU were identified using PubMed, Embase, Web of Science, and Cochrane search engines; references were searched to identify additional studies. Study Selection Included studies were observational in design and included at least 1 outcome in common with other studies and at a concurrent time point of exposure to omalizumab. A total of 67 articles (35.2% of those screened) were included in the analysis. Data Extraction and Synthesis PRISMA and MOOSE guidelines were followed; independent selection and data extraction were completed by 2 observers. Random-effects meta-analyses were performed. Main Outcomes and Measures Main outcomes were change in weekly Urticaria Activity Score (UAS7; range, 0-42), change in Urticaria Activity Score (UAS; range 0-6) (higher score indicating worse outcome in both scales), complete and partial response rates (percentages), and adverse event rate (percentage). Results Omalizumab therapy was associated with an improvement in UAS7 scores (-25.6 points, 95% CI, -28.2 to -23.0; P < .001; 15 studies, 294 patients), an improvement in UAS scores (-4.7 points, 95% CI, -5.0 to -4.4, P < .001; 10 studies, 1158 patients), an average complete response rate of 72.2% (95% CI, 66.1%-78.3%; P < .001; 45 studies, 1158 patients) with an additional average partial response rate of 17.8% (95% CI, 11.7%-23.9%; P < .001; 37 studies, 908 patients), and an average adverse event rate of 4.0% (95% CI, 1.0%-7.0%; P < .001; any level of severity, 47 studies, 1314 patients). Conclusions and Relevance Benefits and safety of omalizumab in the real-world treatment of CIU meet or exceed results gleaned from clinical trials. These real-world data on omalizumab in CIU may help inform both clinical treatment expectations and policy decision making.

Luo XY, Liu Q, Yang H, Tan Q, Gan LQ, Ren FL, Wang H. OSMR gene effect on the pathogenesis of chronic autoimmune Urticaria via the JAK/STAT3 pathway. Mol Med 2018; 24:28. [PMID: 30134804 PMCID: PMC6016876 DOI: 10.1186/s10020-018-0025-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2018] [Accepted: 05/06/2018] [Indexed: 11/18/2022] Open
Abstract
Background Chronic autoimmune urticaria (CAU) is a common skin disease and remains unclear understanding of pathogenesis in the vast majority of cases. In order to explore a new therapy for CAU, the current study was performed to investigate the possible functioning of the Oncostatin M receptor (OSMR) gene in the autoimmunity of CAU via regulation of the JAK/STAT3 signaling pathway. Methods CAU skin tissues from 24 CAU patients and normal skin tissues from normal subjects were collected. Hematoxylin-eosin (HE) staining was conducted to count eosinophils, and immunohistochemistry was carried out to detect the positive rate of OSMR expression in two kinds of skin tissues. A total of 72 Kunming (KM) mice were selected, and 60 mice were used for establishing CAU models and later transfected with different plasmids. The expression of inflammatory factors was evaluated by enzyme-linked immunosorbent assays (ELISA). Expressions of janus kinase (JAK), signal transducer and activator of transcription 3 (STAT3), interferon-stimulated gene 15 (ISG15), CT10-regulated kinase (CRK), and interferon regulatory factor 9 (IRF9) were identified using Western blot assay and reverse transcription quantitative polymerase chain reaction (RT-qPCR). Epithelial cell proliferation was assessed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay, and cell cycle distribution and cell apoptosis were assessed using flow cytometry. Results The findings confirm that OSMR protein expression and histamine release rate are highly elevated in human CAU skin tissues, and the expression of the JAK/STAT3 signaling pathway-related genes (OSMR, JAK2, STAT3, ISG15, CRK and IRF9) was up-regulated. OSMR gene silencing in CAU mice significantly decreases the content of inflammatory factors (IL-1, IL-6, IFN-γ, and IgE), the number of eosinophils, and reduces the expression of the JAK/STAT3 signaling pathway related genes, and further enhances cell proliferation, promotes cell cycle entry and inhibits apoptosis of epithelial cells. Conclusion All aforementioned results indicate that OSMR gene silencing inhibits the activation of the JAK/STAT3 signaling pathway, thereby suppressing the development of CAU.

Effectiveness of omalizumab in adolescent and adult patients with chronic idiopathic/spontaneous urticaria: a systematic review of 'real-world' evidence. Expert Opin Biol Ther 2018; 18:425-448. [PMID: 29431518 DOI: 10.1080/14712598.2018.1438406] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Accepted: 02/05/2018] [Indexed: 12/31/2022]
Abstract
INTRODUCTION Chronic idiopathic/spontaneous urticaria (CIU/CSU) is a dermatological condition characterized by itchy wheals and/or angioedema of continuous or intermittent duration of ≥6 weeks with a high burden of disease and impact on quality of life. Omalizumab is a recombinant humanized monoclonal antibody that inhibits the binding of IgE to high affinity receptors, and is approved for the CIU/CSU indication. The objective of this systematic review was to evaluate and synthesize the evidence on the real-world effectiveness of omalizumab in CIU/CSU in daily clinical practice. AREAS COVERED This review of 84 observational effectiveness studies covers treatments (dosing, medication use), clinical outcomes (treatment response, disease activity, quality of life), and safety. EXPERT OPINION The clinical outcomes observed across studies underscore the real-world effectiveness of omalizumab in the management of CIU/CSU. Continued treatment may assist patients showing an initial response to achieve a complete treatment response. Response rates are aligned with observed changes in disease activity, symptom experience, and quality of life, and this across subtypes of CIU/CSU. The positive therapeutic profile is complemented by a positive safety profile. The real-world evidence summarized here points convincingly at the high degree of effectiveness of omalizumab in the treatment of CIU/CSU in daily clinical practice.

Abstract
Chronic spontaneous urticaria (CSU) is a common disorder with a prevalence of 1% that is characterized by recurrent wheals, angioedema, or both. CSU is self-limited but in many patients symptoms recur for several years and can be refractory to standard therapies. In this review, we present an illustrative case of a female patient with CSU who, despite taking 15 antihistamines a day in addition to a number of second-line therapies, continued to be refractory to treatment. However, once we initiated subcutaneous treatment with omalizumab 300 mg every 4 weeks, she experienced rapid relief of her CSU symptoms. Through this case, we present a review of the relevant issues, including the efficacy of laboratory tests to identify the cause of a patient's CSU, the association between CSU and thyroid disease and its relevance to treatment options, the recommendation to increase antihistamine dose up to fourfold and possible adverse events associated with this treatment option. We also include a discussion of the use of second-line therapies as well as omalizumab in refractory CSU patients.

Abstract
In patients given a diagnosis of chronic spontaneous urticaria (CSU), there are no obvious external triggers, and the factors that initiate the clinical symptoms of wheal, flare, and itch arise from within the patient. Most patients with CSU have an autoimmune cause: some patients produce IgE autoantibodies against autoantigens, such as thyroperoxidase or double-stranded DNA, whereas other patients make IgG autoantibodies against FcεRI, IgE, or both, which might chronically activate mast cells and basophils. In the remainder of patients with CSU, the nature of the abnormalities has not yet been identified. Accumulating evidence has shown that IgE, by binding to FcεRI on mast cells without FcεRI cross-linking, can promote the proliferation and survival of mast cells and thus maintain and expand the pool of mast cells. IgE and FcεRI engagement can also decrease the release threshold of mast cells and increase their sensitivity to various stimuli through either FcεRI or other receptors for the degranulation process. Furthermore, IgE-FcεRI engagement potentiates the ability of mast cells to store and synthesize de novo inflammatory mediators and cytokines. Administration of omalizumab, by virtue of its ability to deplete IgE, attenuates the multiple effects of IgE to maintain and enhance mast cell activities and hence reduces the ability of mast cells to manifest inflammatory mechanisms in patients with CSU.

Abstract
Omalizumab is a monoclonal antibody against IgE, nowadays approved for the treatment of persistent severe (EU) or moderate-to severe (USA) IgE-mediated asthma but there is also some evidence (case reports and four published clinical trials) on the effectiveness of this medication in urticaria and angioedema. The case of a 42-year-old woman suffering from severe allergic asthma and severe chronic urticaria with concomitant angioedema is presented in the article. She had a life-threatening episode of bronchospasm and larynx edema after exposure to house dust recorded in her medical history. The patient did not respond to standard therapy. The improvement in asthma control and remission of chronic urticaria and angioedema was achieved after introducing the therapy with omalizumab.

Abstract
The identification of the causes of chronic spontaneous urticaria (CSU) is difficult. The recognition of functional autoantibodies against FcεRI and/or against IgE in some patients with CSU led to the concept of autoimmune etiology of the disease. Clinical and laboratory features in a subpopulation of CSU patients also point to an autoimmune etiology of the disease. This review will present and discuss the relevance of functional autoantibodies in CSU pathogenesis and their implications for treatment and prognosis.

Abstract
Omalizumab is a monoclonal anti-immunoglobulin E antibody currently only approved for use in severe, refractory asthma. In recent years, many authors have reported satisfactory results with omalizumab in patients with difficult-to-treat chronic urticaria. As a result, clinical trials were undertaken to broaden the indication of omalizumab to include chronic urticaria, and the drug was recently cited as a third-line treatment after selective antihistamines at high doses in a consensus document on the treatment of chronic urticaria. In this article our aim is to provide a comprehensive update on the use of omalizumab in the treatment of chronic urticaria. The structure of this biologic agent and its possible mechanisms of actions in this setting will be presented. Treatment strategies and the different dosage regimens used in the series of cases published to date will also be reviewed. Finally, we will discuss the adverse effects that may arise with treatment and the recommended strategies for minimizing the most feared effect, anaphylaxis. Based on the experience of many researchers, omalizumab is emerging as a novel treatment for certain types of spontaneous refractory chronic urticaria and has shown promising results in this setting. The drug has a good safety profile and the main limitation is its high cost.

Abstract
Omalizumab is a recombinant humanized monoclonal antibody that blocks the high-affinity Fc receptor of IgE. Omalizumab has been approved for the treatment of moderate to severe asthma; however, there is currently more and more data showing promising results in the management also of chronic urticaria. We present a case series of 19 patients with chronic urticaria treated in a university department with omalizumab and give an overview of the existing literature comprising an additional 59 cases as well as a total of 139 patients enrolled in two randomized controlled trials comparing omalizumab with placebo. The collective evidence points to omalizumab as a safe and effective treatment option for patients with chronic urticaria who do not sufficiently respond to standard therapy as recommended by existing guidelines.

Abstract
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 urticaria, including recommending the use of second-generation antihistamines as a first-line therapy. AREAS COVERED A Medline search was conducted from 2000 to 2011 using the following terms, alone or in combination: 'chronic urticaria', 'management guidelines', 'consensus guidelines' and 'expert opinions'. Ten management guidelines/expert opinions met the inclusion criteria. EXPERT OPINION There was a universal agreement among the articles reviewed, that low-sedating, second-generation antihistamines should be prescribed as a first-line treatment of chronic urticaria. For refractory urticaria, however, recommendations varied and included dose escalation of second-generation antihistamines and adjunctive treatments with other agents of the same class, such as sedating antihistamines or leukotriene receptor antagonists. More research into effective second-line treatments and consistent implementation of current guidelines is needed, to ensure that treatment is based on clinical evidence.
