Active clinical trials for "Hypersensitivity"

Eosinophilic esophagitis (EoE) is a chronic inflammatory esophagus disease that is presented in patients with a history of recurrent dysphagia. EoE is closely related to other pathologies with an immuno-allergic etiopathogenesis such as atopic dermatitis (AD), IgE-mediated food allergy, allergic rhinitis and bronchial asthma. While the importance of the correlation between diet and food allergy has been largely demonstrated, less is known about the exact role of sensitization to aerollergens in the progression and recrudescence of symptoms. In support of this correlation there is evidence of a seasonal trend in the new diagnoses of EoE, of the possibility of the de-novo onset of the pathology following massive exposure to a specific aeroallergen and the demonstration that the degree of esophageal eosinophilia varies according to the climatic zone and the season of the year. The detailed knowledge of this correlation could clarify some aspects of the etiopathogenesis and natural history of EoE, improve and personalize the clinical-diagnostic management of affected patients and provide new therapeutic targets. Our aim is evaluating the possible existence of a correlation between the recrudescence of dysphagia symptoms and a specific month of the year and/or specific season.

The purpose of this study is to assess the real-world outcomes differences between apalutamide or enzalutamide plus androgen deprivation therapy (ADT) for the treatment of participants with metastatic hormone-sensitive prostate cancer (mHSPC).

Establish a interstitial lung disease (ILD) registry and biorepository to lead towards a further understanding of the disease.

The Study examines the molecular basis of food allergy. It explores the interaction between T cells, InKT cells and cytokines in the development of food allergy. The study also explores these factors in development of tolerance "outgrowing" food allergy. It will also explore the genetic factors that lead to the development of food allergy. The study examines all type of food allergy including IgE mediated reactions, Eosinophilic Esophagitis and Food Protein Induced Enterocolitis

Malaria, schistosomiasis and ancylostomiasis are three parasitic diseases which affect hundreds of millions of people and are an important cause of global mortality and morbidity. For the control of these poverty related parasitic diseases, and to complement chemotherapeutic strategies, accurate and accessible diagnostic procedures play a crucial role. In recent years, innovative smart mobile technologies have been applied for detection and identification of cultured parasite species, which is basically based on sample imaging and parasite morphology identification. Promising advances have been made with this technology and coupled with its small size, low cost and easy to manipulate, makes it suitable for point of care diagnostics in low resource setting. The aim of the proposed explorative study is to further validate sensitivity and specificity of each of the developed devices, using besides microscopy a range of more advanced reference tests.

Perioperative hypersensitivity reactions are still associated with significant morbidity and mortality despite early recognition and use of epinephrine. The epidemiology of these reactions evolves over time and changes with clinical practice. The main objective is to study the epidemiology of these reactions over a 10-year period, including patient phenotype, reaction phenotype and outcome of the allergic work-up.

Conducting an analysis of the clinical performance of high-sensitivity cardiac troponin I, tested in the out-of-hospital setting, for ruling out cardiac origin in acute onset chest pain. Acute onset chest pain is a complex symptom to narrow down in the out-of-hospital setting. This is due to the difficulty of obtaining pertinent information over the phone, and the absence of validated dispatch scores or criteria. In France, the current standard of care relies on the rapid dispatch of Emergency Medical Response Teams along with a physician in patients presenting symptoms evocative of Coronary Artery Disease or Myocardial Infarction. Typical anginal pain includes retrosternal pressure pain radiating to the jaw, neck, or left arm. Diagnostic work-up includes anamnesis, physical examination, routine blood work, and ECG. In the absence of signification ST-segment modifications, the gold standard relies on trending serum Troponin T and I in the hospital setting . This study aims to analyze the clinical performance of high-sensitivity cardiac Troponin I assays (hs-cTnI) in the out-of-hospital setting using a point-of-care device ; Atellica VTLi (Siemens Healthineers)

Cow's milk protein allergy is a sensitivity reaction against cow's milk protein and and is calcified as IgE-medaited, non- IgE mediated and mixed type according to the underlying immunological mechanism. Cow's Milk related Symptom Score ( CoMiSS) Considers general manifestation and dermatological, gastrointestinal and respiratory symptoms.

Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFA) are an evolving web of clinical conditions characterized by subacute and/or chronic symptoms and include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), food protein-induced allergic proctocolitis (FPIAP), and food protein-induced allergic dysmotility disorders (gastroesophageal reflux disease (GERD), colic and constipation) (FPIMD). Despite the prevalence and clinical impact of these conditions, the pathogenesis as well as the natural history and the best management of these disorders are still poorly defined. These limitations could be responsible for diagnostic delays and errors, and suboptimal clinical management. We aim to evaluate clinical features, natural course and pathophysiology of non-IgE-GIFA in the pediatric age.

The purpose of this study is to strengthen our ability to accurately diagnose allergies and understand cellular, humoral, genetic components and physiological changes in allergic disease
