Abstract
Idiopathic non-histaminergic acquired angioedema (InH-AAE) is a rare disease, with unknown etiology and pathogenesis, characterized by recurrent clinical manifestations and resistance to antihistamines and corticosteroids. We aim to evaluate clinical features and potential markers of disease in an Italian cohort of patients with InH-AAE. We enrolled 26 patients diagnosed with InH-AAE. Information about clinical features, treatments, routine laboratory investigations, immunological and genetic tests were collected. We assessed plasma levels of complement components, angiogenic and lymphangiogenic mediators, proinflammatory cytokines and chemokines, and activity of phospholipases A2. Finally, patients underwent nailfold videocapillaroscopy (NVC); both quantitative and qualitative capillaroscopic parameters were analyzed. Plasma levels of VEGFs were similar in healthy controls and in InH-AAE patients. ANGPT1 was decreased in InH-AAE patients compared to controls while ANGPT2 was similar to controls. Interestingly, the ANGPT2/ANGPT1 ratio (an index of vascular permeability) was increased in InH-AAE patients compared to controls. sPLA2 activity, elevated in patients with C1-INH-HAE, showed differences also when measured in InH-AAE patients. TNF-α concentration was higher in InH-AAE patients than in healthy controls, conversely, the levels of CXCL8, and IL-6 were similar in both groups. At the NVC, the capillary loops mainly appeared short and tortuous in InH-AAE patients. InH-AAE represents a diagnostic challenge. Due to the potential life-threatening character of this condition, a prompt identification of the potentially bradykinin-mediated forms is crucial. A better comprehension of the mechanism involved in InH-AAE would also lead to the development of new therapeutic approaches to improve life quality of patients affected by this disabling disease.

Abstract
BACKGROUND Patients with chronic spontaneous urticaria (CSU) have spontaneous wheals (W), angioedema (AE), or both, for longer than 6 weeks. Clinical differences between patients with standalone W, standalone AE, and W and AE (W+AE) remain incompletely understood. OBJECTIVE To compare W, AE, and W+AE CSU patients regarding demographics, disease characteristics, comorbidities, disease burden, and treatment response. METHODS Baseline data from 3,698 CSU patients in the ongoing, prospective, international, multicenter, observational Chronic Urticaria REgistry (CURE) were analyzed (data cut: September 2022). RESULTS Across all CSU patients, 59%, 36%, and 5% had W+AE, W, and AE, respectively. The W+AE patients, compared with W and AE patients, showed the lowest male-to-female ratio (0.33), higher rates of concomitant psychiatric disease (17% vs 11% vs 6%, respectively), autoimmune disease (13% vs 7% vs 9%, respectively), and nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity (9% vs 5% vs 2%, respectively) and the highest disease impact. The W patients, compared with W+AE and AE patients, showed the lowest rates of concomitant hypertension (15% vs 21% vs 40%, respectively) and obesity (11% vs 16% vs 17%, respectively), the highest rate of concomitant inducible urticaria (24% vs 22% vs 6%, respectively), and shorter W duration. The AE patients, compared with W+AE and W patients, were older at disease onset, showed longer AE duration, and the best response to increased doses of H1-antihistamines (58% vs 24% vs 31%, respectively) and omalizumab (92% vs 67% vs 60%, respectively). CONCLUSIONS Our findings provide a better understanding of CSU phenotypes and may guide patient care and research efforts that aim to link them to pathogenic drivers.

Abstract
Angioedema is generally readily recognizable clinically and is characterized by localized nonpitting edema involving subcutaneous, submucosal, or deep dermal tissue caused by increased vascular permeability and extravasation of intravascular fluid. It can occur via a variety of mechanisms. A number of clinical conditions (masqueraders) are occasionally mistaken for angioedema. Clinical classification of the various angioedema forms begins with noting the presence or absence of concurrent urticaria or wheals. Pathogenesis can be considered through two broad categories: mast cell-mediated with release of vasoactive mediators causing angioedema usually associated with urticaria or in the context of an anaphylactic reaction; and bradykinin (BK)-driven, in which increased vascular permeability is mediated by BK. BK-mediated angioedema does not occur with urticaria, nor does it respond to antiallergic medications. The various forms of hereditary angioedema are included in this category, requiring specific tests of C4 and C1 inhibitor level and function to confirm the diagnosis. Angiotensin converting enzyme inhibitors, which impair the degradation of BK, account for up to a third of all patients with angioedema presenting to the emergency department. Finally, angioedema may occur by yet unknown mechanisms; under this circumstance, it is difficult to manage.

Abstract
Acquired angioedema (AAE) is a rare disease with life-threatening complications. This pathology has classically been associated with medication use and B cell lymphoproliferative disorders. In this report, we describe a 61-year-old man with a six-year history of angioedema, unrelated to any known triggers or malignancy. Extensive workup has led to a diagnosis of idiopathic nonhistaminergic AAE with normal C1 inhibitor. The patient is currently being treated with lanadelumab, which has resolved the patient's symptoms. This case provides insight into the onset, exploration, treatment, and outcomes of an extremely rare disease process.

Abstract
Angioedema (AE) is a vascular reaction of subcutaneous and submucosal tissues that identifies various clinical pictures and often is associated with wheals. AE without wheals (AEwW) is infrequent. The ability to distinguish between AEwW mediated by mast cells and bradykinin-mediated or leukotriene-mediated pathways is often crucial for a correct diagnostic-therapeutic and follow-up approach. AEwW can be hereditary or acquired. Factors typically correlated with hereditary angioedema (HAE) are a recurrence of episodes, familiarity, association with abdominal pain, onset after trauma or invasive procedures, refractoriness to antiallergic therapy, and lack of pruritus. The acquired forms of AE can present a definite cause based on the anamnesis and diagnostic tests. Still, they can also have an undetermined cause (idiopathic AE), distinguished according to the response to antihistamine in histamine-mediated and non-histamine-mediated forms. Usually, in childhood, AE responds to antihistamines. If AEwW is not responsive to commonly used treatments, it is necessary to consider alternative diagnoses, even for pediatric patients. In general, a correct diagnostic classification allows, in most cases, optimal management of the patient with the prescription of appropriate therapy and the planning of an adequate follow-up.

Abstract
Hereditary angiodema with normal C1 inhibitor and unknown mutation (HAE-nC1INH-UNK), an exceedingly rare subtype of HAE, appears to be often diagnosed in patients who do not have this condition, but have mast cell-mediated angioedema. Here, we report two patients diagnosed with HAE-nC1INH-UNK by their physicians, who referred them to our center for treatment continuation with costly kallikrein-kinin-system targeted therapies. We describe how we established the correct diagnosis of recurrent mast cell-mediated angioedema after thorough investigation of both patients and initiated effective treatment with omalizumab. Also, we present and discuss the consensus criteria for diagnosing the very rare condition HAE-nC1INH in light of recent research and based on our own clinical experience. In conclusion, HAE-nC1INH-UNK should only be considered after more common differential diagnoses, i.e., mast cell-mediated angioedema, have thoroughly been investigated and ruled out. This approach reduces both the patients’ disease burden and healthcare costs and contributes to meaningful research.

Abstract
Angioedema (AE) is a reason for emergency care when it is severe. Care is difficult when the diagnostic is not known before the attack: mast cell (MC) or bradykinin (BK) mediated. One is very common but often benign, the other rare but potentially fatal. The French national reference center of angioedema (CREAK) provides emergency physicians with a hotline and a guideline to help them manage their patients. This study aimed to describe the clinical features of AE episodes prompting a call on the CREAK hotline and classify patients depending on the suspected cause of the AE. This is a retrospective study between March and August 2019. Each physician calling on the CREAK hotline was asked to fill a clinical description form for the AE emergency. Known patients of CREAK was excluded. Eighty four patients were included. Forty one (48.8%) in the angiotensin converting enzyme inhibitors induced acquired angioedema (ACEi-AAE), 39 (46.4%) in the mast cell induced angioedema, and 4 (4.8%) in the Bradykinin mediated angioedema. The mast cell induced angioedema patients have more history of hives (29.3%) than ACEi-AAE (2.4%, P = .0004). ACEi-AAE mainly affected the tongue (58.5% vs 25.6%, P = .003) and larynx (29.3% vs 13%, P = .001). In 65.5% of cases, the etiological diagnosis was not mentioned by the appellant, but made by the hotline. In 31% of cases, the hotline suggested the administration of a specific treatment not previously provided by the caller. All the doctors who called the hotline appreciate this tele-expertise especially in case of ACEi-AAE presumptions. In addition to providing rapid AE expertise, this service also allows to educate physicians in the management of AE irrespective of its origin.

Abstract
BACKGROUND Omalizumab has been shown to improve outcomes in patients with chronic spontaneous urticaria (CSU). Idiopathic angioedema (IAE) is increasingly being recognized as a condition with similar underlying mechanisms as CSU and a form of CSU. We hypothesized that add-on therapy with omalizumab would benefit patients with uncontrolled IAE. OBJECTIVE To study the safety and efficacy of omalizumab for the treatment of IAE in adults. METHODS We conducted a randomized, placebo-controlled trial to study the efficacy of omalizumab in adults with two or more episodes of angioedema (AE) in the past 6 months for which no clinical or laboratory cause of AE could be found. Ten patients were randomized on a 1:1 basis to receive omalizumab 300 mg SQ or placebo every 4 weeks for 24 weeks with a 12 week follow up period. The primary endpoint was the change in the Angioedema Activity Score (AAS). Secondary endpoints included the Angioedema Quality of Life Questionnaire (AE-QoL), the Visual Analog Scale (VAS) and the number of angioedema episodes per month. RESULTS We observed improvement in the AAS score (-2.93 ln odds; 95% confidence interval (CI) -4.84, -1.02; p = 0.003), VAS (-3.49 ln odds; 95% CI -6.58, -0.40; p = 0.03), AE-QoL (-9.43 score; 95% CI -17.63, -1.24; p = 0.028) and number of angioedema episodes per month (-1.93 ln count; 95% CI -3.23, -0.63; p = 0.005) in patients that received omalizumab vs placebo. CONCLUSION This study provides preliminary prospective evidence that omalizumab improves outcomes in patients with IAE.

Shirazi MT, Kenari HM, Eghbalian F. The Role of Bloodletting and Cupping in Severe Acute Urticaria and Angioedema as Skin Emergencies in Persian Medicine. J Pharmacopuncture 2022; 25:7-14. [PMID: 35371590 PMCID: PMC8947972 DOI: 10.3831/kpi.2022.25.1.7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 11/17/2021] [Accepted: 12/01/2021] [Indexed: 11/09/2022] Open
Abstract
Objectives Some dermatological diseases can be life-threatening. Urticaria and angioedema are common reasons for patients to seek treatment at an emergency department. Severe, generalized urticaria and angioedema can endanger patients’ lives by involving the airways and causing anaphylactic shock. The humor-based Persian Medicine (PM) concepts of Shara and Mashara, referring to two kinds of skin lesions, have similarities to urticaria and angioedema, respectively. This article aims to provide scientific evidence regarding the application of PM as an early intervention strategy in the emergency management of urticaria and angioedema. Methods This was a narrative review of PM studies identified by searching medical databases using search terms related to these diseases, as well as risk-associated keywords such as “fatal”, “death”, “life-threatening”, “emergency”, “cupping”, and “bloodletting”. Data were then compared, interpreted, and analyzed. Results PM scholars consider the human body as a unified whole and believe in an inner power (Nature) which stems from the body. When the presence of excessive hot substances cause an imbalance of bodily humors, Nature directs their heated vapors sharply toward the skin, thus causing Shara and Mashara. If there is a high risk of inflammation spreading to vital organs under severe conditions, urgent manual interventions are crucial. Conclusion In serious conditions of urticaria and angioedema, Fasd or bloodletting and Hijama can be effective in speeding up the control of lesions and reducing morbidity and mortality. Consequently, the development of integrated Persian and conventional medicines may provide new therapeutic pathways for skin emergencies.

Abstract
Angioedema (AE), transient localized swelling due to extravasated fluid, is commonly classified as mast cell mediator-induced, bradykinin-mediated or of unknown cause. AE often occurs more than once, and it is these recurrent forms of AE that are challenging for patients and physicians, and they are the ones we focus on and refer to as AE in this review. Since effective treatment depends on the causative mediator, reliable and early diagnosis is essential. Although their clinical presentations bear similarities, many forms of angioedema exhibit specific patterns of clinical appearance or disease history that may aid in diagnosis. Here, we describe the most common differences and similarities in the mechanisms and clinical features of bradykinin-mediated and mast cell mediator-induced types of angioedema. We first provide an overview of the diseases that manifest with mast cell mediator-induced versus bradykinin-mediated angioedema as well as their respective underlying pathogenesis. We then compare these diseases for key clinical features, including angioedema location, course and duration of swelling, attack frequency, prevalence and relevance of prodromal signs and symptoms, triggers of angioedema attacks, and other signs and symptoms including wheals, age of onset, and duration. Our review and comparison of the clinical profiles of different types of angioedema incorporate our own clinical experience as well as published information. Our aim is to highlight that mast cell mediator-induced and bradykinin-mediated angioedema types share common features but are different in many aspects. Knowledge of the differences in underlying pathomechanisms and clinical profiles between different types of angioedema can help with the diagnostic approach in affected patients and facilitate targeted and effective treatment.

Abstract
Angioedema and hereditary angioedema are characterized by swelling of the subcutaneous and/or submucosal tissue, resulting in localized oedema. The rarity, but also the diverse clinical presentation, of these conditions can be challenging regarding diagnosis, treatment, and management. Patient-reported outcome measures (PROMs) are data received directly from the patient, providing the patient's perspective on various subjects regarding health and well-being. PROMs can be helpful tools to optimize treatment and long-term management of conditions. A major challenge regarding the consistent use of PROMs in clinical settings in Scandinavia is language availability; many of the validated PROMs for hereditary angioedema and angioedema lack translations into the Nordic languages. The litterature search yielded 9 different PROM tools for angioedema and hereditary angioedema. Five were found suitable for use in clinical practice in Europe. Even though several PROMs exist they are not used consistent. Accessible electronic PROMs and careful planning is required to implement PROMs optimally in routine care processes.

Hereditary angioedema: a disease seldom diagnosed by pediatricians. J Pediatr (Rio J) 2021; 97 Suppl 1:S10-S16.

Abstract
OBJECTIVES To describe the hereditary angioedema to improve awareness of this condition and reduce diagnostic delay. DATA SOURCES Relevant articles in the MEDLINE database through PubMed. DATA SYNTHESIS Hereditary angioedema is rare and has an autosomal dominant pattern of inheritance. Its onset occurs mainly in childhood, but there is an important delay in the diagnosis. In the most frequent phenotype, there is a quantitative and/or functional deficiency in the C1esterase inhibitor protein, which regulates the activation of the complement, contact and fibrinolysis systems with greater formation of bradykinin, the main mediator of angioedema. There is a third type, the hereditary angioedema with a normal C1 inhibitor level, which is rare in children. Clinical manifestations are characterized by recurrent angioedema attacks, mainly in the extremities, abdomen and upper airways, which can progress to asphyxia and death. The main triggers are mechanical trauma, infections and stress. The diagnosis is attained by patient clinical picture and decreased serum levels of C4 and C1esterase inhibitor or its function. In hereditary angioedema with a normal C1 inhibitor, there is no change in these parameters, thus requiring a genetic study. Treatment is based on the use of attack medications and long and short-term prophylaxis. CONCLUSIONS Hereditary angioedema is little known by pediatricians due to the significant delay in diagnosis of this condition, whose onset usually begins in childhood. The presence of recurrent angioedema that does not respond to treatment with antihistamines, corticosteroids and adrenaline should increase the diagnostic suspicion.

Abstract
The ongoing COVID-19 pandemic has produced serious turmoil world-wide. Lung injury causing acute respiratory distress syndrome seems to be a most dreaded complication occurring in ∼30%. Older patients with cardiovascular comorbidities and acute respiratory distress syndrome have an increased mortality. Although the precise mechanisms involved in the development of lung injury have not been fully elucidated, the role of the extended renin-angiotensin system seems to be pivotal. In this context, angiotensin-converting enzyme 2 (ACE2), an angiotensin-converting enzyme homologue, has been recognized as a facilitator of viral entry into the host, albeit its involvement in other counter-regulatory effects, such as converting angiotensin (Ang) II into Ang 1-7 with its known protective actions. Thus, concern was raised that the use of renin-angiotensin system inhibitors by increasing ACE2 expression may enhance patient susceptibility to the COVID-19 virus. However, current data have appeased such concerns because there has been no clinical evidence of a harmful effect of these agents as based on observational studies. However, properly designed future studies will be needed to further confirm or refute current evidence. Furthermore, other pathways may also play important roles in COVID-19 transmission and pathogenesis; spike (S) protein proteases facilitate viral transmission by cleaving S protein that promotes viral entry into the host; neprilysin (NEP), a neutral endopeptidase known to cleave natriuretic peptides, degrades Ang I into Ang 1-7; NEP can also catabolize bradykinin and thus mitigate bradykinin's role in inflammation, whereas, in the same context, specific bradykinin inhibitors may also negate bradykinin's harmful effects. Based on these intricate mechanisms, various preventive and therapeutic strategies may be devised, such as upregulating ACE2 and/or using recombinant ACE2, and exploiting the NEP, bradykinin and serine protease pathways, in addition to anti-inflammatory and antiviral therapies. These issues are herein reviewed, available studies are tabulated and pathogenetic mechanisms are pictorially illustrated.

Abstract
Angioedema is a non-inflammatory oedema of the subcutaneous tissue and/or mucosal membranes. It most commonly coexists with urticaria wheals and is considered to be a deep form of urticaria. Less commonly, it occurs in isolation and can take two basic forms: acquired angioedema and hereditary angioedema. Currently, there are 4 defined types of acquired angioedema and 7 types of hereditary angioedema. Treatment of angioedema depends on its form and etiological factors. Especially the genetic form, i.e. hereditary angioedema, is a considerable challenge for medical specialists, particularly dermatologists and allergists.
