Active clinical trials for "Angioedema"

The main aim of this study is to describe the characteristics of participants, check for number of hereditary angioedema (HAE) cases, their treatment and outcomes. Another aim is to check how the healthcare facilities were utilized for treatment. Participants' data will be taken from their medical records (charts), which were already collected as a part of their routine care between January 1, 2012, and January 1, 2022.

Angioedema is a disease characterized by the appearance of self-limiting edema that last 1-5 days and affect the subcutaneous tissue and/or gastrointestinal and oropharyngeal mucosa. In this last location edema can be lethal causing asphyxia, in all other cases full recovery is complete. Attacks can appear as part of the syndrome urticaria angioedema and can be of allergic origin. But there is a group of non-allergic angioedema that occur without hives and can be either hereditary or acquired. These angioedema are identified in some cases on the basis of etiology, in others are identified by the mediator and an overall classification of these forms of angioedema was published in 2014 as a result of a consent conference organized by the proponents of this registry. Being these forms of angioedema rare, there are not significative case studies inclusive of a high number of patients. This registry aims to collect in a single place a high number of subjects with recurring angioedema and without urticaria.

The main aim of this study is to describe the treatment patterns, characteristics and outcomes of people with HAE who are currently receiving icatibant in the homecare setting in the United Kingdom (UK). Participants will be treated with icatibant according to their routine practice via homecare service for icatibant within the UK. Data will be directly collected from participants via study diaries and questionnaires. Participants will be contacted approximately every 90 days during study duration (this can occur via phone or as a face-to-face visit).

The main aim of this study is to learn about how many persons with HAE type I or type II are attack-free when treated with lanadelumab in real life, how many attacks occur and how many of these attacks need rescue treatment and about the nature of HAE attacks. Participants will need to visit their doctor 5 times in total as part of this study. The visits are planned every 6 months. Participants will also be asked to fill out questionnaires as part of this study.

Angiotensin-Converting-Enzyme-inhibitors-dependent angioedema (ACEi-AE) is the most frequent form of bradykinin-mediated AE, with an estimated prevalence of 0.1% to 0.7%. These AE can be explained by the accumulation of bradykinin (BK), a peptide responsible for increase of vascular permeability: ACE inhibitors block ACE, the main inactivation pathway of the BK, thus extending its half-life. In spite of the the stopping of the drug, systematically performed in the case of ACEi-AE, up to 50% of patients relapsed within 6 months, with maximum risk in the first month after stopping. In addition, the discontinuation of these drugs represents a loss of chance for some patients, without clearly established mastocytic (or histaminic) or bradykinic etiology. At present there is no method to predict the risk of crisis recurrence in patients who have developed AE-IEC. The investigators hypothesize that the risk of relapse is associated with a decrease in the activity of BK degradation enzymes (including aminopeptidase P (APP), dipeptidyl peptidase-4 (DPP4), and ECA) that persists at the cessation of IEC.

The unpredictable nature of the attacks is one of the essential characteristics of bradykinin angioedema. The two main difficulties for physicians managing a patient with bradykinin angioedema are to make the diagnosis and anticipate the severity. Biomarkers can be used to diagnose, guide treatment, or predict the severity of a disease. However, the identification of biomarkers is currently difficult in bradykinin both for diagnosis and prognosis. While measurement of C4 and C1 inhibitor (quantitative and functional assays) allows the diagnosis of bradykinin angioedema due to C1 inhibitor deficiency, whether genetic or acquired, many patients with normal C1 inhibitor bradykinin angioedema, either hereditary or acquired, are still difficult to diagnose. For patients with hereditary angioedema with C1-inhibitor deficiency, there is no biomarker currently available to predict the severity. Any biomarker that could improve the diagnosis on the one hand, and improve the prediction of the frequency and severity of the response to treatment on the other hand, would obviously be extremely useful. The aim of our study is to assess the existence possible biomarkers for diagnosis and prognosis of bradykinin angioedema.

Longitudinal prospective multicenter Armenian registry of systemic autoimmune, autoinflammatory diseases with constitution of bio-banking.

Individuals with heart disease or high blood pressure are often prescribed angiotensin converting enzyme (ACE) inhibitors to treat their disease. However, the use of ACE inhibitors can be associated with angioedema, a rare but life-threatening condition that causes swelling of the face and other body parts. This study will evaluate the effectiveness of the drug HOE-140 at decreasing symptoms of angioedema in people taking ACE inhibitors who develop the condition.

The objectives of this survey are to collect data to report the safety and efficacy of Firazyr (Icatibant acetate) in the post-marketing phase in participants diagnosed with Hereditary Angioedema (HAE).
