Urticaria.

Allergy Asthma Clin Immunol

December 2024

Urticaria (hives) is a common disorder that may be associated with angioedema (swelling that occurs beneath the skin). It is generally classified as acute or chronic, and chronic urticaria is further classified as spontaneous or inducible Second-generation, non-sedating histamine type 1 (H1)-receptor antihistamines represent the mainstay of therapy for both acute and chronic urticaria. Second-line treatment for uncontrolled chronic urticaria includes omalizumab (a monoclonal anti-immunoglobulin E [IgE] antibody).

Article Synopsis
  • Primary immunodeficiency diseases (PIDs) are genetic immune system disorders requiring lifelong immunoglobulin replacement therapy, usually delivered through IVIG or SCIG infusions.
  • Ig20Gly, a 20% immune globulin solution, is a replacement therapy approved for various age groups, with recent approvals for manual administration in Europe aimed at simplifying the process.
  • Manual administration of Ig20Gly allows for faster infusion rates, similar safety and satisfaction levels compared to infusion pumps, and potential cost savings for healthcare systems due to lower equipment and nursing needs.

Article Synopsis
  • The study examines Hereditary angioedema with normal C1-inhibitor function (HAE nC1-INH) and idiopathic angioedema of unknown etiology (AE-UNK) in Canada by analyzing electronic health records from 2012 to 2022.
  • Out of 60 patients analyzed, the average age of symptom onset was 21.5 for HAE nC1-INH and 23 for AE-UNK, with significant differences in triggers for episodes and treatment received post-diagnosis.
  • The results highlight that while most patients received long-term prophylaxis after diagnosis, the types of treatments and the prevalence of angioedema attacks varied between the two conditions, indicating distinct

Background: COVID-19 vaccination has been associated with anaphylaxis and hypersensitivity reactions. Infectious disease physicians and allergists in the Canadian Special Immunization Clinic (SIC) Network developed guidance for evaluating patients with adverse events following immunization (AEFI) including suspected hypersensitivity. This study evaluated management and adverse event recurrence following subsequent COVID-19 vaccinations.

Introduction: Angiotensin Converting Enzyme Inhibitors (ACEI) are a common cause of Emergency Room presentation for angioedema. Although no treatment guidelines exist, C1 esterase inhibitor concentrate (C1-INH) is used on an off label basis for management of ACEI acquired angioedema (ACEI AAE).

Objective: To evaluate the efficacy of C1-INH in management of ACEI AAE at our local centers.

Background: This is a retrospective review of the Winnipeg Regional Health Authority's (WRHA) angioedema patients who were dispensed icatibant in hospital. Icatibant is a bradykinin B2 receptor antagonist indicated for Hereditary Angioedema (HAE) types I and II and is used off-label for HAE with normal C1INH (HAE-nC1INH) and ACE-inhibitor induced angioedema (ACEIIAE). The WRHA's use of icatibant is regulated by the Allergist on call.

Background: It is a putatively understood phenomenon that the overall prevalence of allergic disease has been increasing in recent decades-particularly in industrialized nations. Despite this, there is a relative scarcity of data concerning the development of food-related allergic disease in the adult population. In addition, the paucity of data as it pertains to the Canadian population is particularly marked when compared to other nations.

Background: Both intravenous and subcutaneous human immune globin G (IgG) replacement (IVIG and SCIG, respectively) reduce severe infection and increase serum IgG levels in primary immune deficiency disorder (PIDD) patients who require replacement. SCIG can be administered either with the aid of an infusion pump, or by patients or caregivers themselves, using butterfly needles and a syringe ("SCIG push"). SCIG offers advantages over IVIG, including higher steady state IgG levels, improved patient quality of life indicators, and decreased cost to the healthcare system, and for these reasons, SCIG has been increasingly used in Manitoba starting in 2007.

Objective: This study sought to evaluate available evidence of the safety of penicillin skin testing (PST), challenge, and desensitization in pregnancy, with efforts to improve perinatal care for patients with a penicillin allergy history and mitigate the negative sequelae of unverified penicillin allergy labels.

Methods: A systematic review of studies was conducted using Cochrane Library, Medline, EMBASE, and International Pharmaceutical Abstracts. Included were peer-reviewed studies without date restrictions, published in English or French, relating to PST, challenge, or desensitization in pregnancy.

Background: Hereditary angioedema with normal C1 inhibitor (HAE-nC1 INH) is a rare, underappreciated condition characterized by recurrent subcutaneous angioedema. The underlying pathophysiology and diagnostic criteria continues to evolve. There is a significant overlap between HAE-nC1 INH and idiopathic nonhistaminergic angioedema, ultimately this may be found to be the same condition.

Background: Adult onset food allergy is a rare, but increasingly recognized phenomenon. Mast cell activation syndromes present an ongoing diagnostic and classification challenge. The combination of the two has been rarely described in the literature.

Background: A history of penicillin allergy in patients is common, but only 10-15 % are truly allergic. While the gold standard for diagnosing penicillin allergy is challenge, it is not recommended that this be done without first carrying out diagnostic skin testing. This is carried out with the major determinant benzylpenicilloyl (PPL) and the minor determinant mixture (MDM), consisting of penilloate, penicilloate and Penicillin G.

Background: H1N1 is responsible for the first influenza pandemic in 41 years. In the fall of 2009, an H1N1 vaccine became available in Canada with the hopes of reducing the overall effect of the pandemic. The purpose of this study was to assess the safety of administering 2 different doses of a monovalent split virus 2009 H1N1 vaccine in egg allergic patients.

Background: We published the Canadian 2003 International Consensus Algorithm for the Diagnosis, Therapy, and Management of Hereditary Angioedema (HAE; C1 inhibitor [C1-INH] deficiency) in 2004.

Objective: To ensure that this consensus remains current.

Methods: In collaboration with the Canadian Network of Rare Blood Disorder Organizations, we held the second Canadian Consensus discussion with our international colleagues in Toronto, Ontario, on February 3, 2006, and reviewed its content at the Fifth C1 Inhibitor Deficiency Workshop in Budapest on June 2, 2007.
