Project description:BackgroundChronic urticaria (CU) is a common skin disorder, which can be further divided into chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU). Omalizumab is effective and safe for difficult-to-treat CSU based on clinical trials. However, there are limited data comparing the therapeutic effect of omalizumab for patients with CSU, CIndU, and CSU plus CIndU. Meanwhile, there is still no reliable predictor for treatment response or relapse. Our study was conducted to collect real-world clinical data on omalizumab treatment in patients with CSU, CIndU, and both.MethodsThis was an observational, retrospective chart review of patients with CU initiating omalizumab treatment between February 2018 and May 2020 (maximum 28 months follow-up).ResultsA total of 138 patients were included, 87 with CSU alone, 33 with different forms of CIndU, and 18 with both. A total of 87.0% (n = 120/138) of the CU patients responded to omalizumab therapy, among which 65.2% (n = 90/138) of the patients showed complete response and 21.7% (n = 30/138) of the patients showed partial response. The therapeutic effect and speed of onset of effect for omalizumab were comparable among patients with CSU, CIndU, or both. Autologous serum skin test (ASST)-positive patients were more likely to show a slow response to omalizumab therapy ( P = 0.043). Non-responders had lower baseline total IgE levels (35.0 vs 121.5 kU/L, P < 0.001). The proportion of patients with low total IgE levels in non-responders was significantly higher than that of responders (61.1% vs. 14.5%, P < 0.001). Also, more non-responder patients had elevated thyroid autoantibodies than responders (50.0% vs. 23.0%, P = 0.041). The median ratio of serum IgG-anti-TPO to serum total IgE in non-responders was significantly higher compared with responders (1.22 vs. 0.09, P < 0.001). Non-responders also had shorter treatment periods (4.5 vs 6.0 months, P = 0.035) compared with responders. Two of 3 patients (67.4%, n = 29/43) experienced relapse after ceasing omalizumab therapy. These patients had longer disease durations (52.0 vs. 15.0 months, P = 0.007) and higher baseline total IgE levels (179.9 vs. 72.5 kU/L, P = 0.020) than patients who did not relapse. We reinitiated omalizumab treatment for 10 relapsed patients, all of them reported a rapid response after the first injection within the first 4 weeks of retreatment.ConclusionOmalizumab is highly effective in patients with difficult-to-treat CSU, CIndU, or both. Responders tend to have unique immunological features and longer treatment periods. Patients with higher baseline total IgE levels and longer disease durations are more likely to experience rapid relapse after discontinuation of omalizumab.

Project description:This is Part 1 of an updated follow-up review of a World Allergy Organization (WAO) position paper published in 2012 on the diagnosis and treatment of urticaria and angioedema. Since 2012, there have been advances in the understanding of the pathogenesis of chronic urticaria, and greater experience with the use of biologics, such as omalizumab, in patients with severe refractory disease. For these reasons, the WAO decided to initiate an update targeted to general practitioners around the world, incorporating the most recent information on epidemiology, immunopathogenesis, comorbidities, quality of life, clinical case presentations, and the management of chronic spontaneous and chronic inducible urticaria, including urticaria in special situations such as childhood and pregnancy. A special task force of WAO experts was invited to write the different sections of the manuscript, and the final document was approved by the WAO Board of Directors. This paper is not intended to be a substitute for current national and international guidelines on the management of urticaria and angioedema but to provide an updated, simplified guidance for physicians around the world who manage patients with this common ailment.

Project description:Introduction Chronic inducible urticaria (CIndU) is a subgroup of chronic urticaria induced by a specific stimulus. We evaluated basophil characteristics in patients with CIndU and compared with those in patients with chronic spontaneous urticaria (CSU) and healthy controls (HCs). Methods Blood was collected from patients, and a basophil activation test (BAT) was performed. Basophil responsiveness and surface marker expression in patients with CIndU were compared with those in patients with CSU and HCs. For some patients with CIndU, blood was collected before and after wheals were induced. In these cases, we compared the responsiveness of basophils before and after the appearance of wheals. Result HCs (n=23) and patients with CIndU (n=24) or CSU (n=38) were enrolled in the study. The degree of basophil activation at steady state in patients with CIndU was higher than in HCs. Basophil responsiveness via high-affinity IgE receptor (FcϵRI) stimulation with anti-IgE or anti-FcϵRI antibody in patients with CIndU was equivalent to that in HCs, and higher than that in patients with CSU. No abnormalities in IgE and FcϵRI expressions on the surface of basophils in patients with CIndU were observed. When we induced wheals in some patients with CIndU and performed a BAT before and after the appearance of wheals, no significant changes were found. Conclusion Peripheral blood basophils in CIndU were slightly activated at steady state, but no abnormalities in basophil responsiveness. In future, a higher number of cases should be enrolled to confirm the role of basophils and refine therapeutic targets for CIndU.

Project description:Urticaria and angioedema are very common. Management of chronic urticaria subtypes, which usually persist for many years, is challenging. Recent years have demonstrated that targeting IgE with antibodies provides a safe and efficient treatment approach. Whilst several anti-IgE antibodies have been developed, omalizumab is currently the only one approved for use. International and national guidelines recommend its use after failure of antihistamines at standard and increased dose. Whilst not yet approved, many new anti-IgE approaches are currently being investigated in pre-clinical studies or clinical trials. This non-systematic focused review summarizes current knowledge of omalizumab and other anti-IgE biologics in chronic urticaria using data extracted from PubMed, Google Scholar and clinical trial databases, clinicaltrials.gov and clinicaltrials.eu. For adults, there is good evidence from randomized clinical trials and real-world data that symptomatic treatment with omalizumab is efficacious and safe in chronic spontaneous urticaria (CSU), whereas evidence in chronic inducible urticaria (CINDU) and special populations is limited. Easy-to-use tools to identify non-responders and predict the required duration of treatment have not been established yet. Phase 2 b results of ligelizumab have not only demonstrated efficacy and safety but also superiority to omalizumab. Indeed, there is preliminary evidence that omalizumab non- or partial responders benefit from ligelizumab. Whereas further development of quilizumab was discontinued, other approaches, eg UB-221 or DARPins are under investigation. Anti-IgE treatment with omalizumab represents a landmark in the treatment of chronic urticaria, with and without angioedema, and there is light on the horizon suggesting success may come with various next-generation anti-IgE approaches.

Project description:Chronic urticaria is a common inflammatory skin disease affecting around 0.5-1% of the world's population. The disease has a chronic indolent course which significantly affects the patient's quality of life. Urticaria pathogenesis involves cross-linking of immunoglobulin E (IgE) on mast cells causing degranulation which occurs by various pathways which leads to development of wheals and angioedema. The first-line treatment for chronic urticaria is non-sedating second-generation H1 antihistamines (AHs). After the advent of anti-IgE monoclonal antibody omalizumab, the response rate in resistant urticaria has improved significantly without any major adverse events. Other biologicals such as anti-IgE, anti-IL-5, anti-IL-1, anti-IL-17, and anti-CD20 monoclonal antibodies are under trial. These biologicals have better efficacy and safety profile as compared to conventional immunosuppressants. Even with the advances in the last decade, recurrence after stopping the therapy is common, and there is a need for better understanding of the pathogenesis and the drugs acting on the key pathways involved in urticaria. In this review, we provide the role of several biologicals in the treatment of chronic urticaria.

Project description:In a prospective study a comparison has been made between the clinical efficacy and safety of cetirizine, a third generation H1 receptor antagonist with chlorpheniramine and cyprohepatadine, the most widely used antithistamines in the treatment of chronic idiopathic urticaria. One hundred and five patients with chronic idiopathic urticaria were studied where the effects of chlorpheniramine, 4 mg and cyproheptadine, 4 mg administered twice daily were compared with cetirizine, 10 mg given once daily for 4 weeks or earlier till the relief of symptoms and regression of lesions. Local therapy consisted of calamine lotion in all cases. Out of 35 patients receiving chlorpheniramine excellent response was achieved in 9 (25.7%) cases by subjective evaluation (SE) and 11 (31.4%) by objective evaluation (OE). Out of 35 cases, 7 (20%) and 10 (28.5%) cases treated with cyproheptadine have shown excellent response by SE and OE respectively. Out of 35 patients taking cetirizine 25 (71.4%) had shown excellent response by SE and 22 (62.8%) cases by OE. Drowsiness was an important side effect observed in 19 (54.2%) cases receiving chlorpheniramine, 22 (62.8%) patients taking cyproheptadine and 1 (2.8%) case getting cetirizine. These results suggest that cetirizine has got superior antiallergic activity than chlorpheniramine and cyproheptadine in the treatment of chronic idiopathic urticaria.

Project description:Chronic spontaneous urticaria (CSU) is a disease with significant morbidity and relative prevalence that has important effects on the quality of life (QoL) of those who suffer from it. Omalizumab is a recombinant humanized anti-immunoglobulin E (IgE) antibody that binds to the Cε3 domain of the IgE heavy chain and prevents it from binding to its high-affinity receptor FcεRI. It has been largely studied in the field of asthma and is currently approved for the treatment of both adult and pediatric (children; >6-year-old) patients. In addition, in recent, well-controlled clinical trials in patients with CSU resistant to antihistamines, add-on therapy with subcutaneous omalizumab significantly reduced the severity of itching, and the number and size of hives, and increased patients' health-related QoL and the proportion of days free from angioedema compared with placebo, with an excellent tolerance. Thus, omalizumab is an effective and well-tolerated add-on therapy for patients with CSU who are symptomatic despite background therapy with H1 antihistamines. In this review, we cover the following points: epidemiology, pathogenesis, assessment of activity, impact on QoL, and treatment of CSU, and finally, we focus on omalizumab in the treatment of CSU including the pharmacokinetic properties and mechanism of action, and use in pregnant women, nursing infants, and children.

Project description:A wide range of pharmacological and nonpharmacological interventions for chronic urticaria (CU) have been evaluated in systematic reviews (SRs). We conducted an umbrella review of SRs of the effectiveness and safety of pharmacological and nonpharmacological interventions for CU, which allow the findings of separate reviews to be compared and contrasted and thereby provide decision makers in healthcare with the evidence they need.We included SRs evaluating pharmacological and nonpharmacological interventions for CU. Comprehensive searches were conducted in 7 bibliographic databases, relevant journals up to July 2018. Two reviewers independently assessed the studies' relevance and quality. The assessment of multiple systematic reviews tool and grading of recommendations assessment, development and evaluation method was used to assess the methodological quality of the SRs and classify the quality of the outcomes.In total, 41 SRs were included. Thirty-seven reviews performed quantitative research syntheses, and 4 reviews performed qualitative research syntheses. The majority of SRs evaluated interventions based on combination therapies, antihistamines, traditional Chinese medicines, autohemotherapy, omalizumab, acupuncture, cyclosporine, and leukotriene receptor antagonist. Positive intervention outcomes were reported in the majority (75.32%) of the reviews. However, the methodological quality and evidence quality of the reviews were generally poor.There is some evidence to support a variety of interventions for CU. However, there was much heterogeneity in evidence quality among SRs. Many of the SRs had methodological weaknesses that make them vulnerable to bias. Moreover, there remained little information on the relative effectiveness of one intervention compared with another. Therefore, further SRs that adherence to strict scientific methods are necessary, and primary studies make comparisons between the different treatment options directly.

Project description:BackgroundChronic urticaria (CU) is a common disease which represents a considerable burden for many patients. The current urticaria guideline describes the evidence-based diagnosis and treatment of CU. In addition, however, questions often arise in everyday practice that are not addressed by the guideline.MethodsIn May 2020, a digital meeting with German urticaria experts was held, in which practical aspects of CU treatment were discussed and supporting aids for everyday clinical treatment formulated. The resulting advice in this document focus on practical questions and the available literature and experiences of the participants.ResultsThe diagnosis of CU can be made in a short time by means of a thorough anamnesis, a physical examination, and a basic laboratory chemical diagnosis. For this purpose, practical recommendations for everyday practice are given in this paper. An extended diagnosis is only indicated in a few cases and should always be carried out in parallel with an effective therapy. In general, CU should always be treated in the same way, regardless of whether wheals, angioedema or both occur. Symptomatic therapy should be carried out according to the treatment steps recommended by the guidelines. This publication provides practical advice on issues in everyday practice, such as the procedure in the current coronavirus disease 2019 (COVID-19) pandemic, the cardiac risk under higher dosed H1 antihistamines, the self-administration of omalizumab as well as vaccination under omalizumab therapy. In addition to treatment recommendations, topics such as documentation in the practice and family planning with urticaria will be discussed.DiscussionThese supporting treatment recommendations serve as an addendum to the current CU guideline and provide support in dealing with CU patients in everyday practice. The aim is to ensure that patients suffering from CU achieve complete freedom of symptoms with the help of an optimal therapy.Supplementary informationThe online version of this article (10.1007/s40629-021-00162-w) contains supplementary material, which is available to authorized users.
