Active clinical trials for "Hypersensitivity"

To assess the efficacy of skin tests with platinum salts in patients suspects with immediate hypersensitivity reactions. All patients adressed in consultation to the Allergy Department of university hospital of nancy for an immediate hypersensitivity reaction to platinum salts between 2015 and 2021 were retrospectively recruited.

Several protocols have been proposed in scientifis literature, for oral tolerance induction (OIT) protocols for peanuts. A meta-analysis showed that the data in the literature are rather in favor of the exclusion of peanuts, and that OIT doesn't allow to expect significant levels of peanut protein consumed by the patient, and is associated with an increased risk of anaphylaxis and epinephrine use. Also, in most published protocols, patients with a history of anaphylactic shock, severe asthma, or multiple history of anaphylaxis are excluded. To date, no protocol has been validated for this type of treatment, and each center follows locally validated schemes. In our unit, the investigators use an OIT protocol that starts at low doses (first dose at 2.68 mg peanut protein) and doses increase is scheduled every 4 to 12 weeks (instead of every 2 weeks). The investigators do not exclude patients with asthma or those with a history of peanut anaphylaxis (grade 2 or 3). The investigators have noted that our protocol is associated with a good safety profile and good efficacy, probably due to the fact that the investigators start at low doses and increase the dose with a prolonged delay, compared to previously published protocols. For this reason, the investigators decided to evaluate the results the investigators obtained in our patients and to better analyze the efficacy and safety profile of our protocol.

Background Cetuximab (trade name Erbitux) is a murine-human chimeric monoclonal antibody to human epidermal growth factor receptor (EGFR). This drug has been used as a treatment for colorectal cancer and head and neck cancer. It is known that allergic reactions can occur in more than 5% of the patients, although the side effects are relatively low compared with other chemotherapeutic agents. It is known that cetuximab can induce hypersensitivity even at the first administration, unlike other anticancer drugs. In this study, we aimed to establish a model to predict patients with hypersensitivity reaction before administration of cetuximab and to provide safe chemotherapy. Recruitment method and consent procedure The study is designed for analysis patients scheduled for administration of cetuximab for the first time. Patients matching the selection and exclusion criteria with voluntary agreement to the study will be enrolled. Enrolled patients will be tested for skin prick test and serum sIgE before cetuximab administration.

A measurable degree of heart muscle tissue injury is expected in patients undergoing heart valvular surgery. The level of this injury can be measured by cardiac biomarkers in blood samples. Those biomarkers are used to diagnose an acute myocardial infarction. Postoperative myocardial infarction (MI) is a frequent and important complication after cardiac surgery with high morbidity and mortality. Therefore it is very important to recognize any cardiac event in patients who undergo cardiac surgery. Different diagnostic tools can be used to the diagnosis of acute myocardial infarction; however few is known about the value of high-sensitivity cardiac troponin T (hs-cTn) to diagnose a MI after heart valvular surgery. The aim of this study is to determine the upper reference limit of high-sensitivity troponin T concentration to consider the diagnosis of acute myocardial infarction in patients undergoing heart valvular surgery.

Pterygium is the growth of conjunctival tissue onto the cornea, usually from the nasal quadrant of the cornea.Visual acuity may be reduced due to direct invasion of the visual axis or astigmatism induced by the pterygium. Contrast sensitivity measures two variables, size, and contrast which could comprehensively reflect the visual quality of the primary pterygium patients. In this study, we would investigate the the effects of primary pterygium on contrast sensitivity preoperatively and on the 1st, 3rd and 6th month postoperatively, moreover, the related parameters on the contrast sensitivity in the primary pterygium patients would be analyzed.

Dendritic cells (DC) play a key role in the pathogenesis of allergic diseases. The regulation of blood dendritic cells in patients with hymenoptera venom allergy before and during immune therapy is unknown.

This study investigates the effect of exercise on pain sensitivity in ongoing neck pain patients compared to a healthy control group.

Acute pancreatitis (AP) is a potentially life-threatening disease with varying severity of presentation. Nearly 60%-80% of all cases of AP in developed countries are attributable to either gallstone disease or alcohol abuse. The incidence is similar in both sexes, although alcohol abuse is the more common cause in men and gallstones is the more common cause in women.

revising penicillin allergy in the medical records, by taking full medical history and giving a challange test, in order to imrove the medical records and treatment possibilities.

Allergic diseases, including allergic asthma, allergic rhinitis and anaphylaxis are not properly classified in current classifications of diseases. We here propose a project based on the evaluation of medical records of hospital databases of patients suffering for allergic and hypersensitivity conditions coded with the current and a new coming version of the international classification of diseases, no patient or intervention will be analysed. We here propose a study to update and reach quality assurance of the classification of allergic and hypersensitivity conditions in international classification systems. The Allergic and hypersensitivity conditions section has indeed been recently built into the new ICD-11 framework and we aim to reach its quality assurance by evaluating medical records of French hospital databases. All the consecutive cases related to allergic and hypersensitivity conditions registered in the last 1 year will be selected and blind-coded by two independent coders based on the online English versions of the ICD-10 (2015 version) and ICD-11 Beta draft. The generated data will support the intra and inter-variability testing, survey among end-users and economic-impact evaluation. The economic impact of the transition from ICD-10 to ICD-11 will be analysed based on average estimated cost per day of each principal diagnosis and the effect of the classification change will be quantified by the cost variance of inter or intra diagnosis of ICD-10 and ICD-11. For the bridge procedure based on the alignment of the allergic and hypersensitivity conditions described into the ICD-10 (and ICD-10 CM US adaptation) framework to the ICD-11 beta phase, we propose the mapping and cross-linking terms methods. Meanwhile, we will start updating the allergic and hypersensitivity procedures by influencing the International Classification of Health Intervention (ICHI).
