Urgent diagnosis of hereditary angioedema in the ICU and ED: the critical role of rapid complement testing - a case report.
(PubMed, Int J Emerg Med)
- "This case highlights the importance of considering HAE in patients presenting with unexplained slowly-evolving angioedema without urticaria, when traditional histamine-directed therapies fail, especially when airway compromise is imminent. Awareness that C4 levels are universally low during HAE attacks, is key. C4 testing is widely available and prompt communication with biochemistry or immunology laboratories facilitates rapid turnaround. Urgent presumptive diagnosis facilitates appropriate emergency management and prompt referral for definitive diagnosis and management. Early identification and management of HAE can significantly reduce morbidity and mortality associated with this condition."

Association between Toll-like receptor 9 signaling defect and developing post-infectious irritable bowel syndrome.
(PubMed, Front Immunol)
- "Furthermore, administration of BDKRB1 antagonist R715 and BDKRB2 antagonist HOE 140 significantly suppressed visceral hyperalgesia. TLR9 deficiency leads to bradykinin receptor upregulation in the colonic epithelium following infectious colitis, contributing to the development of PI-IBS. Inhibition of these receptors alleviated visceral pain, indicating that bradykinin receptor antagonists may offer a novel therapeutic strategy for PI-IBS."

Recurrent Airway Swelling in a Patient With Lymphoproliferative Disorder: A Diagnostic Challenge Between Anaphylaxis and Acquired Angioedema.
(PubMed, Cureus)
- "Considering refractory anaphylaxis, she received intravenous dexamethasone, an adrenaline nebulizer, and an adrenaline infusion. Given her history of CD5-negative low-grade B-cell lymphoproliferative disorder, a diagnosis of acquired angioedema was made following multidisciplinary review, and treatment with icatibant was initiated. This case highlights the importance of considering bradykinin-mediated angioedema in patients with recurrent "refractory anaphylaxis." The absence of urticaria, normal tryptase, and low complement levels should prompt evaluation for C1-INH deficiency, allowing timely, targeted management and improved outcomes."

Current Use of Hereditary Angioedema (HAE) Treatments in Sweden: An Analysis of the National Prescribed Drug Register
(ISPOR-EU 2025)
- "Icatibant was the most dispensed concomitant treatment to LTP, followed by pdC1-INH. The observed prevalence aligns with prior estimates, though the incidence, when measured as number of new patients treated for HAE, is higher than what has been observed elsewhere. Despite restrictive reimbursement criteria, lanadelumab is the most prescribed LTP. The dispensing of on-demand/short-term treatment at least three times annually, indicates that a large share of patients potentially are not attack-free despite treatment with LTP."

A Case of HAE-ANGPT1 Treated with berotralstat - Insights into Pathophysiology
(ACAAI 2025)
- "Although some patients with ANGPT1 mutations have responded to icatibant—a bradykinin B2 receptor antagonist—the role of bradykinin-generating pathways, such as the contact activation system, remains poorly understood. While ANGPT1 mutations are thought to act via endothelial dysfunction, this response suggests a role for the kallikrein-kinin system. These findings support further exploration of contact pathway inhibitors in managing this HAE subtype."

Deucrictibant vs. Standard of Care in Hereditary Angioedema: A Propensity Score-Matched Analysis
(ACAAI 2025)
- P2/3 | "MMS data (collected November 2022 until April 2023) included 29 participants (69% female; mean [range] age 41 [18-70]), with attacks most often treated with icatibant (60.2%) or C1INH concentrate (31.7%). Among 85 non-laryngeal attacks matched between the cohorts, median estimates (95% confidence intervals) for time (hours) to different outcomes of improvement were shorter for deucrictibant vs SOC on time to the following outcomes: 1.68 (1.03-1.93) vs 2.23 (1.56-3.07, p=0.0001) for PGI-C at least “a little better”, 2.93 (2.03-3.95) vs 4.56 (3.33-6.18; p=0.0005) for PGI-C at least “better”, and 2.38 (1.93-2.95) vs 4.02 (3.04-5.19; p=0.0001) for PGI-S 1-level improvement. Conclusion This PSM analysis showed that a cohort of participants with HAE in a clinical study treated with deucrictibant had more favorable outcomes on some PGI-C/S assessments than a cohort treated with SOC in an observational study."
