Active clinical trials for "Hypersensitivity"

The aim of this study is to show that flow cytometry can be an accurate tool to help physicians regarding the diagnosis, the SIT decision and the SIT arrest of hymenoptera venom allergy. 75 patients having a story of reaction to hymenoptera venom will be selected for this trial. Blood samples will be analyzed at: inclusion visit, Week 1 visit, Week 3 visit, Week 10 and Week 21 visit.

Milk is the among the most common food allergens in infants and children. The majority of children outgrow their allergies; however, the exact mechanisms by which food tolerance is achieved are unknown. Strict avoidance of the offending food is currently the only known therapy. However, subjects have been known to lose food hypersensitivity while frequently ingesting small amounts of processed forms of the offending product. The purpose of this study is to investigate whether ingestion of small amounts of processed milk protein will be permitted without compromising the chances of either outgrowing milk hypersensitivity or prolonging the time needed to achieve clinical tolerance.

This study is designed to identify whether wines which are produced using the common potential food allergens such as proteins derived from fish, milk or egg are likely to contain sufficient food allergens to cause allergic reactions in susceptible individuals.

OBJECTIVES: I. Determine whether there is prompt engraftment after autologous peripheral blood stem cell transplantation using filgrastim (G-CSF) mobilization in patients with life threatening autoimmune diseases. II. Determine the kinetics of T- and B-cell immune reconstitution after a combination of timed plasmapheresis, high dose cyclophosphamide and total lymphoid irradiation, and posttransplant immunosuppression with cyclosporine in these patients. III. Determine whether this treatment regimen beneficially influences the clinical course of these patients.

Cow's milk protein allergy is defined as an immunological reaction to one or more milk proteins. A variety of symptoms can be suggestive for cow's milk protein allergy . Cow's milk protein allergy is suspected clinically in 5-15% of infants, while most estimates of prevalence of cow's milk protein allergy vary from only 2 to 5 %. Confusion regarding cow's milk protein allergy prevalence is often due to differences in study populations, study design and a lack of defined diagnostic criteria. The importance of defined diagnostic criteria needs to be emphasised. It precludes infants from an unnecessary diet and avoids delay in diagnosis, which can lead to malnutrition. The treatment of cow's milk protein allergy is the dietary elimination of cow's milk proteins. In non-breastfed infants and children less than 2 years of age, a substitute formula is mandatory as prescribed by several international scientific societies. Extensively hydrolyzed formulas are used as therapeutic formulas. An extensively hydrolysed formula is often a whey or casein based formula in which the protein has been chopped up in smaller pieces that are less allergenic. Because of high cross-reactivity (up to 80%) and nutritional inadequacy, the use of any other animal milk or soy-based formula is precluded.The infant should be maintained on an elimination diet until the child is between 9-12 months of age or at least for 6 months, whichever occurs first. In most cases, symptoms will improve substantially within 2-4 weeks if diagnosis is correct. According to consensus in literature, a therapeutic formula is a formula tolerated by at least 90% (with 95% confidence) of cow's milk protein allergy infants. The primary study outcome will be the evaluation of the hypoallergenicity of a new aminoacid based formula in children with confirmed immunoglobulin (Ig)E- mediated CMA. According to the American Academy of Pediatrics (AAP) Subcommittee on Nutrition and Allergic Diseases a hypoallergenic formula must be tested in infants and children with hypersensitivity to cow's milk proteins, with findings verified by elimination-challenge tests under double-blind, placebo-controlled conditions (DBPCFC).

The investigators aimed to study the cut-off of high sensitivity troponin T using SYSMEX HLSCL Machine in Thai population at percentile 99.

The study will be a single-center, longitudinal, triple-masked (for participants, operators, and statistician), equal ratio, randomized non-crossover design. The study designed following the criteria described by Holland et al 1997. The current experiments will follow CONSORT guidelines and will be registered at the US National Institutes of Health (ClinicalTrials.gov). The sensitivity scores will be measured at three intervals: at baseline, at 2 weeks, and at 6 weeks. The duration of the current study estimated to be 6 weeks and will be conducted between January 2020 and March 2020. The study protocol will be submitted initially to the Ethical Committee of the Aseer Central Hospital, Aseer region, Saudi Arabia. After getting the approval and facilitation letters, the participants will be selected randomly from patients attending periodontal clinics at Aseer Dental Center, Aseer region.

Patients with type-1 diabetes are more susceptible to motility-related upper gastrointestinal symptoms. Dietary interventions are one of the treatment pillars for these symptoms. Many gastrointestinal conditions other than celiac disease, are being increasingly treated with gluten-free diet (GFD). The role of GFD in non-celiac type-1 diabetic patients with dyspepsia-like symptoms has not been assessed before. In this study, type 1 diabetes patients with concomitant upper gastrointestinal symptoms will be asked to follow a 1-month GFD to assess changes in upper gastrointestinal symptoms and gastroduodenal motility before and after the dietary intervention.

Irritable Bowel Syndrome (IBS), or functional colopathy, is a chronic disease that affects 10% to 20% of the world's population.This syndrome is characterized by chronic abdominal pain or discomfort as well as a change in bowel habits (constipation or diarrhea) in the absence of structural or metabolic abnormalities (e.g. celiac disease, Crohn's disease). These symptoms have an impact on the quality of life of these patients who must therefore integrate the management of their disease into their daily life.IBS is subdivided into 3 subtypes according to the predominant symptom: the IBS-D subtype which groups together patients who have a predominance of diarrheal episodes, the IBS-C subtype which groups together patients who have a predominance of '' episodes of constipation and finally the IBS-M subtype which includes patients whose two symptoms mentioned above are observed without predominance

This project aims to investigate the sensitivity and specificity of the rapid antigen test compared to RT-PCR test performed on samples from the nasopharynx and the anterior nasal cavity and the oropharynx, respectively.
