Do cross-food allergies to propofol exist?
Alergia a la comida; Sensibilización alimentaria; PropofolFood allergy; Food sensitization; PropofolAl·lèrgia alimentà ria; Sensibilització alimentà ria; PropofolBackground: Propofol is a short and rapidly acting intravenous anesthetic extensively used for the induction and maintenance of general anesthesia. It is a lipid emulsion that contains soybean oil, purified egg phosphatide, and egg lecithin. Therefore, the package leaflet indicates that its administration is contraindicated in patients allergic to soy, eggs, or peanuts. Our study aimed to determine whether patients with proven food allergies are allergic to propofol.
Methods: Patients of all ages allergic to soy, eggs, or peanuts who agreed to undergo skin testing for propofol allergies were included. The subjects first underwent a skin test to confirm food allergies. If candidates were negative, they were excluded. If the result was positive, a propofol skin test was performed.
Results: Sixty-four patients with confirmed food allergies underwent a propofol skin test. Only one was positive in the propofol skin test (1.6%). The patient was allergic to peanuts and soybeans. These results reinforce the idea that there is no justification for avoiding propofol use in these subjects.
Conclusions: Propofol can be safely administered to patients allergic to soy, eggs, or peanuts. We recommend caution in patients with a history of anaphylaxis after ingestion of the above-mentioned foods

COVID-19 Course in Allergic Asthma Patients: A Spanish Cohort Analysis
COVID-19; Asthma; EosinophilsCOVID-19; Asma; EosinófilosCOVID-19; Asma; EosinòfilsPurpose: The acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has had a high impact on patients with chronic diseases. In the literature, there are different perspectives on asthma as comorbidity or risk factor on COVID-19 severity.
Patients and methods: The aim of this retrospective study across 13 allergy departments in Spain was to determine the severity of COVID-19 in asthmatic adults followed in allergy departments and its relationship with atopy, clinical and demographic characteristics, phenotypes and laboratory data. In addition, lung function test and asthma control test (ACT) before and after COVID-19 were analyzed. Data was obtained from electronic medical records from March 2020 to April 2021.
Results: Two hundred one asthmatic patients were diagnosed with COVID-19 infection by validated detection test. About 30% of the patients were admitted for bilateral pneumonia. Advanced age, elevated D-dimer, lower numbers of lymphocytes and eosinophils, heart diseases and hypertension were associated with severe COVID-19. Allergic and mixed allergic/eosinophilic phenotype and their biomarkers (total IgE, aeroallergens sensitizations, allergic rhinitis, and blood eosinophilia) were related to fewer hospital admissions. Poor control and lower forced expiratory volume in the first second (FEV1) were related to worse prognosis of COVID-19.
Conclusion: Asthmatic patients with allergic and eosinophilic phenotype have a better evolution of COVID-19 and lower risk of admissions. Older patients, cardiovascular comorbidities, AERD and eosinopenia are related to severity COVID-19
