Filter by:Use of first-line pre-operative antibiotic prophylaxis is the most effective measure to optimize perioperative outcomes. However, this is often not achieved due to unsubstantiated penicillin allergy labels. Penicillin allergy evaluation, when incorporated into routine pre-operative assessment, is potentially effective in optimizing choice of surgical prophylaxis. Despite the encouraging data mentioned above, there is a lack of randomized trials or local data to support this practice.
The purpose of this study is to characterize immune cells using single-cell transcriptomic analysis in pediatric patients aged 2 to 18 years undergoing general anesthesia who are expected to receive Rocuronium, a non-depolarizing neuromuscular blocking agent, in the event of an allergic reaction.
There are limited studies on perioperative hypersensitivity (POH) reactions in children. The diagnosis of POH might be underestimated due to the difficulty of recognizing the reactions. Anaphylaxis may go unnoticed due to the unconscious state of the patient. Urticaria may be overlooked due to the sterile covers. This study aimed to evaluate POH reactions prospectively.
The aim of this study is to find out whether TAK-880 creates hypersensitivity reactions compared to Gammagard S/D by testing blood taken from participants who have a higher risk of becoming hypersensitive to immunoglobulin products. This study is about collecting data available in the participant's medical record. No study medicines will be provided to participants in this study. Each participant will fill out a study questionnaire during a routine doctor visit. Blood will be taken from participants who have a higher risk of developing hypersensitivity reactions to immunoglobulin products.
A investigational study to establish: 1. A validated cllinical pathway for delabeling declared Penicillin allergiy outside allergologic departments. 2. A survey to examine anesthesiologists attitudes and knowledge about penicillin delabeling. 3. A qualitative focus group study investigating barriers and facilitators in penicillin delabeling among hospital nurses and physichians. 2. Implement the pathway for delabeling declared penicillin allergy outside allergologic clinics across the Western Norway health region.
The study will identify pediatric patients 3-18 years old who have penicillin allergy label in the electronic medical record. Those who are identified will be stratified into no-risk, low-risk and high-risk category using a screening questionnaire. The following definitions will be followed: No-risk: Patients who are historically labeled with penicillin allergy in the EMR based on family history alone OR those who have tolerated penicillin after a concerning incident without any reaction OR with penicillin allergy label but deny any history of reaction to any form of penicillin on screening questionnaire Low-risk: Patients with previous reaction not suggestive of anaphylaxis (defined below) AND not requiring hospitalization for the reaction OR reaction considered non- immunologic (e.g. diarrhea, nausea, yeast vaginitis) OR exposure to penicillin- containing antibiotic after the date of reported reaction with no anaphylaxis and hospitalization AND no serious types of delayed reactions such as Steven- Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), acute interstitial nephritis (AIN), drug-induced hepatitis or other documented organ injury, drug rash eosinophilia systemic symptoms (DRESS), hemolytic anemia, drug-induced cytopenia, and serum sickness. Patients who had delayed reaction (onset more than 24 hours) of isolated, non-progressive symptoms (such as rash/hives alone) also belong to this group. High-risk: Patients with penicillin allergy label on EMR with previous reaction suggestive of anaphylaxis (defined below) OR requiring hospitalization/epinephrine administration for the reaction OR reactions considered immunologic (angioedema, joint pains) OR involving serious types of reactions such as Steven-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), acute interstitial nephritis (AIN), drug-induced hepatitis or other documented organ injury, drug rash eosinophilia systemic symptoms (DRESS), hemolytic anemia, drug-induced cytopenia, and serum sickness. Patients who were previously diagnosed with penicillin allergy by an allergist also belong to the high-risk group. Patients in the no-risk group will be immediately delabeled. Patients in the high-risk group will be referred to allergy/immunology for further work up. The focus of this study is to identify the patients who belong to the low-risk group. This group of patients will be subjected to graded oral amoxicillin challenge testing. Those who will have reactions compatible with allergy will have their allergy status retained in the electronic medical record. Those that will not have reactions or those that will have reactions that are not compatible with allergy will be delabeled in the electronic medical record.
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.
The aim of this study is to investigate the degree of match between the drug allergy label in the hospital's electronic health record and primary care's electronic health record among patients who previously have been drug allergy tested.
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.
