Active clinical trials for "Hypersensitivity"

Grass pollen allergens are recognised as a major cause of allergic diseases in humans and animals. Worldwide, at least 40% of allergic patients are sensitised to grass pollen allergens and between 50-90% of hayfever or seasonal allergy sufferers are allergic to grass pollen. ToleroMune Grass is a novel, synthetic, allergen-derived peptide desensitising vaccine, currently being developed for the treatment of grass allergy. The purpose of this optional observational follow-on study is to further evaluate rhinoconjunctivitis symptoms on exposure to Grass in the EEU among subjects who completed all dosing visits in study TG002 approximately two years after the start of treatment.

This study evaluates the effects of Nickel oral hyposensitization treatment (NiOHT) on health-related quality of life (HRQoL) of patients suffered from Systemic Nickel Allergy Syndrome (SNAS).

The purpose of this study is to confirm of assay sensitivity of Driving Simulator by positive control

Women experience negative psychological outcomes long after the violent relationship has ended. Women suffer constant trauma and psychological distress being in emotional and mentally abusive relationship. Present study developed Culturally sensitive cognitive-behaviour therapy (CBT) to fit the client's cultural identity, context, and preferences.

Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. Study objectives: Personalized drug sensitivity test for late stage,potentially operable gastrointestinal cancer using patient derived primary cell culture. Explore the clinical feasibility of using primary cell culture system to guide gastrointestinal cancer chemotherapy, and establish the correlation between ex vivo drug sensitivity and patient clinical response. The study will collect primary tumor tissues from stage III/IV gastrointestinal cancer patients who underwent emergency surgeries, and then establish the primary tumor cell library for ex vivo chemotherapy drug sensitivity test in order to: Compare the ex vivo Maximal Inhibition Index(MI) and Drug Sensitivity Index (DSI) with patient's Overall Response Rate (ORR) Provide research support for future clinical treatment. This ex vivo method applies to single or combination drug regimen, and does not require prior knowledge of the specific mechanism for individual patient's drug sensitivity. Previous research as well as literature studies support the close relationship between ex vivo drug sensitivity and in vivo drug response.

The aim of the study is to assess the safety of an oral food challenge (OFC) with cow's milk proteins and to assess the tolerance of cow's milk proteins in children with a food allergy after introducing cow's milk into the diet.

Hypersensitivity pneumonitis (HP) is an inflammatory lung disease that is caused by exposure of susceptible individuals to organic materials in the environment. It is also known by various names depending on the exposure and some of these names include farmer's lung, pigeon breeder's lung, hot tub lung to name a few. HP can cause lung scarring that impairs breathing and oxygenation. Early detection and avoidance of triggers can stop and reverse the disease but a significant number of patients continue to have active disease requiring treatment in spite of avoiding the trigger. The current choice of therapies is based on clinical experience and not on rigorous clinical trials. Not fully understanding the type of inflammation that is seen in HP and the cells involved in this inflammatory response limits health care providers' ability to choose drugs to study in HP that can stop the inflammation and limit scar formation. The goal of the investigators' study is to better understand the type of cells that are involved in the inflammatory response in the lungs of HP patients and what drives these cells to be active. By better understanding the type of cells and what drives them, health care providers can begin to choose and study drugs that can limit the inflammation and subsequent scarring. The investigators' will recruit HP patients and with their consent perform a scope of the lungs (bronchoscopy) with a limited lung wash to get the inflamed cells out of the lungs to further study them in the lab. The investigators' study will provide us with preliminary results to guide us in performing a more detailed study in the future to better understand the disease.

This study aims to investigate whether protein fortification of foods and beverages causes mouthdrying and mucoadhesion and whether this is influenced by age and saliva flow.

Repeated insult patch test on healthy males and females to determine potential contact irritation or contact allergy in the skin

The EAT Study showed a reduction in both sensitisation (to all foods) and clinical food allergy (to peanut and egg) among children who consumed allergenic food early compared with those who followed standard government feeding advice to exclusively consume breast milk for the first 6 months of life. The EAT-On Study aims to establish whether the effects seen at 3 years in the EAT study represent a delay in FA onset or sustained tolerance. EAT-On will also investigate the natural history (emergence and resolution) of FA in childhood; thus shaping dietary and management plans for allergic patients. Findings will inform future research and weaning recommendations for preventing FA.
