Current and Future Approaches in Management of Chronic Spontaneous Urticaria Using Anti-IgE Antibodies.

Medicina (Kaunas) 2022 Jun 17;58(6). Epub 2022 Jun 17.

Dermatology Department, "Elias" University Emergency Hospital, 011461 Bucharest, Romania.

Chronic spontaneous urticaria (CSU) considerably alters patients' quality of life, often for extended periods, due to pruriginous skin lesions, impaired sleep, unexpected development of angioedema, and failure of conventional treatments in properly controlling signs and symptoms. Recent research focused on the development of new therapeutic agents with higher efficacy. Although the production of specific immunoglobulin E (IgE) antibodies against certain allergens is not a characteristic of the disease, treatment with omalizumab, a monoclonal anti-IgE antibody, proved efficient and safe in patients with moderate to severe chronic spontaneous urticaria uncontrolled by H1-antihistamines.

A case of acquired angioedema.

JAAPA 2022 May;35(5):36-38

Arielle D. Zwanziger practices in family medicine at Kaiser Permanente of Washington in Seattle. The author has disclosed no potential conflicts of interest, financial or otherwise.

Abstract: Acquired angioedema is a rare disorder characterized by nonurticarial angioedema secondary to deficiency or altered activity of C1-esterase inhibitor protein. This article describes a patient whose recurrent angioedema was initially diagnosed as angiotensin-converting enzyme (ACE) inhibitor-induced angioedema. However, after further testing, she was diagnosed with acquired angioedema and subsequently treated with a synthetic bradykinin B2-receptor antagonist. Read More

Practical Management of New-Onset Urticaria and Angioedema Presenting in Primary Care, Urgent Care, and the Emergency Department.

Eric Macy

Perm J 2021 11 22;25. Epub 2021 Nov 22.

Allergy Department, Southern California Permanente Medical Group, Kaiser Permanente Southern California, San Diego, CA.

A new episode of urticaria and/or angioedema can be an anxiety-inducing event for both the patient and the physician(s) seeing them in primary care, urgent care, or the emergency department. These events are commonly mistaken for "allergic" reactions and often mistreated. The most common causes of new onset urticaria in older children and adults, with or without angioedema, and normal vital signs or hypertension, are post-infection or acute idiopathic urticaria.

Clin Transl Allergy 2021 Dec;11(10):e12083

Department of Internal Medicine and Haematology, Hungarian Angioedema Center of Reference and Excellence, Semmelweis University, Budapest, Hungary.

Background: Angioedemas localized in the upper airway are potentially life threatening, and without proper treatment, they may lead to death by suffocation. Upper airway edemas (UAE) in bradykinin-mediated angioedemas can even be the first symptoms of the disease.

Methods: Our survey was performed with a retrospective long-term follow-up method from the medical history of 197 hereditary (C1-INH-HAE) and 20 acquired C1-inhibitor deficiency (C1-INH-AAE), 3 factor XII and 3 plasminogen gene mutation (FXII-HAE, PLG-HAE) patients treated at our center between 1990 and 2020.

Hungarian Angioedema Center of Reference and Excellence, Department of Internal Medicine and Haematology, Semmelweis University, Budapest, Hungary.

Angioedema is a prevailing symptom in different diseases, frequently occurring in the presence of urticaria. Recurrent angioedema without urticaria (AE) can be hereditary (HAE) and acquired (AAE), and several subtypes can be distinguished, although clinical presentation is quite similar in some of them. They present with subcutaneous and mucosal swellings, affecting extremities, face, genitals, bowels, and upper airways. Read More

Malignancy and immune disorders in patients with hereditary angioedema.

Allergy Asthma Clin Immunol 2021 Dec 19;17(1):134. Epub 2021 Dec 19.

Division of Allergy and Immunology, Department of Medicine, University of British Columbia, 905-750 Broadway W, Vancouver, BC, V5Z 1H8, Canada.

Background: Hereditary angioedema (HAE) is an inherited condition manifesting as recurrent angioedema episodes which is caused by deficiency or dysfunction of C1 inhibitor. Although complement dysregulation has historically been shown to be associated with various malignancy and immune disorders, it is currently not known if HAE patients are at an increased risk of developing malignancy or autoimmune conditions.

Case Presentation: We reviewed the charts of 49 HAE patients and identified 6 patients who had a co-existing malignancy diagnosis (two with breast cancer, one with melanoma, one with pancreatic cancer, one with renal cancer and one with cervical dysplasia) and 6 patients who had a diagnosis of a co-existing immune disorder (two with rheumatoid arthritis, two with ulcerative colitis, one with chronic urticaria with hypothyroidism and one with Sjogren's syndrome).

Physicochemical and Biological Characterization of rhC1INH Expressed in CHO Cells.

Pharmaceuticals (Basel) 2021 Nov 19;14(11). Epub 2021 Nov 19.

JSC "GENERIUM", 14, Vladimirskaya Street, Volginskiy 601125, Vladimir Region, Russia.

The disfunction or deficiency of the C1 esterase inhibitor (C1INH) is associated with hereditary or acquired angioedema (HAE/AAE), a rare life-threatening condition characterized by swelling in the skin, respiratory and gastrointestinal tracts. The current treatment options may carry the risks of either viral infection (plasma-derived Berinert) or immune reaction (human recombinant C1INH from rabbit milk, Ruconest). This study describes the physicochemical and biological characterization of a novel recombinant human C1 esterase inhibitor (rhC1INH) from Chinese hamster ovary (CHO) cells for the treatment of hereditary angioedema compared to the marketed products Berinert and Ruconest.

Resolution of Laryngeal Oedema in a Patient with Acquired C1-Inhibitor Deficiency. a Case Report.

J Crit Care Med (Targu Mures) 2021 Apr 12;7(2):136-140. Epub 2021 May 12.

George Emil Palade University of Medicine, Pharmacy, Science, and Technology of Targu Mures, Mures Romania.

Introduction: Laryngeal oedema caused by acquired angioedema due to C1-inhibitor deficiency (C1-INH-AAE) is a life-threatening condition. The swelling is bradykinin mediated and will not respond to the usual treatment with antihistamines, corticosteroids, or epinephrine. Instead, kallikrein-bradykinin-targeted therapies should be used promptly to prevent asphyxiation. Read More

Acquired angioedema in B cell lymphoproliferative disease: A retrospective case series.

Clin Exp Immunol 2021 12 11;206(3):378-383. Epub 2021 Oct 11.

Division of Pulmonary, Allergy, and Critical Care Medicine, Duke University Medical Center, Durham, North Carolina, USA.

Acquired angioedema due to C1-inhibitor (C1-INH) deficiency (AAE-C1-INH) is rare and is associated with underlying lymphoproliferative diseases. C1-INH deficiency may be due to neoplastic over-consumption of C1-INH and the generation of anti-C1-INH autoantibodies. Uncovering an occult malignancy can lead to earlier oncology referral and improvement of angioedema after treatment of the underlying lymphoproliferative disorder. Read More
