Hereditary angioedema (HAE), due to C1-inhibitor deficiency, is a rare autosomal dominant and potentially life-threatening disease characterised by recurrent oedema attacks of skin, mucosa and viscera. Due to the rarity and the fact that symptoms of HAE imitate other forms of angioedema and other conditions, HAE may be misdiagnosed, especially in emergency settings. Consequently, patients with HAE may experience significant delays in diagnosis. Without an accurate diagnosis patients with HAE may not receive proper treatment. At times 'Doctor Google' may be an important tool in establishing the diagnosis. The aim of this case report is to emphasise the importance of listening to patients and relatives and being humble to 'Doctor Google'. Furthermore, the aim is to remind all healthcare personal of HAE and the importance of considering the rare differential diagnoses to common symptoms.

Phenotypic and molecular characterization of the largest worldwide cluster of hereditary angioedema type 1.

PLoS One

Hereditary angioedema type 1 (HAE1) is a rare, genetically heterogeneous, and autosomal dominant disease. It is a highly variable, insidious, and potentially life-threatening condition, characterized by sudden local, often asymmetric, and episodic subcutaneous and submucosal swelling, caused by pathogenic molecular variants in the SERPING1 gene, which codes for C1-Inhibitor protein. This study performed the phenotypic and molecular characterization of a HAE1 cluster that includes the largest number of affected worldwide.

Real-world Effectiveness of Lanadelumab in Hereditary Angioedema: Multi-country INTEGRATED Observational Study.

J Allergy Clin Immunol Pract

December 2024

EUCAN Medical Affairs, Takeda Pharmaceuticals International AG, Glattpark-Opfikon (Zürich), Switzerland.

Background: Hereditary angioedema (HAE) is a rare genetic disease characterized by recurrent episodes of cutaneous or subcutaneous edema. There is clinical need for treatments that reduce the rate of HAE attacks in patients.

Objectives: Primary objectives were to evaluate the effectiveness of lanadelumab on attack free rate (AFR; proportion of patients who had zero HAE attacks), and on every two weeks (Q2W) and every four weeks (Q4W) adjustments on AFR.

Background: Hereditary angioedema (HAE) is clinically characterized by recurrent attacks of cutaneous and submucosal swelling.

Objective: To investigate real-world timing, potential barriers, and impact of delaying on-demand treatment (OD) of HAE attacks METHODS: Patients with HAE (type I or II) aged ≥12 years with ≥1 treated (Treated Cohort) or untreated (Untreated Cohort) attack in the past 3 months were recruited by the US HAE Association. Respondents completed a 20-minute, self-reported, online survey about their last HAE attack.

Clinical Response and Corresponding Blood Transcriptome Pathways Pre- And Post-Treatment Of Hereditary Angioedema Prodromes Compared To Active Swelling Attacks.

J Allergy Clin Immunol

December 2024

University of Cincinnati College of Medicine, Department of Internal Medicine, Division of Rheumatology, Allergy and Immunology, Cincinnati, Ohio; Bernstein Allergy Group, LLC and Bernstein Clinical Research Center, LLC. Electronic address:

Rationale: Approximately 85% Hereditary angioedema (HAE) attacks are associated with prodromal symptoms. We investigated the clinical effect of treating HAE-C1 inhibitor (HAE-C1INH) Type 1 patients with Conestat Alfa® (recombinant human C1-INH) during their prodrome versus an active swelling episode and associated changes in blood transcriptomic genes and pathways pre- vs. post-treatment.

Study of Urinary Protein Biomarkers in Hereditary Angioedema.

J Investig Allergol Clin Immunol

December 2024

Department of Allergy and Clinical Immunology, National Clinical Research Center for Immunologic Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: Hereditary angioedema (HAE) is a rare and potentially life-threatening disease, and diagnosis is often missed or delayed. We aimed to identify noninvasive urinary protein biomarkers and to evaluate their potential roles in diagnosis and evaluation of disease severity.

Methods: Using data-independent acquisition (DIA)-based urinary proteomics, we identified proteins that were differentially expressed between patients with HAE and healthy control (HC) groups.
