Iatrogenic causes of anaphylaxis, such as by drugs and vaccines, can be fatal and are a major concern to the public.^(1-3) On the other hand, inappropriate apprehension towards the possibility of anaphylaxis may lead to COVID-19 vaccination delays or hesitancy, which are relevant impediments against achieving protective immunity for individuals and our community.³ Recently, Krantz and colleagues performed a retrospective analysis and observed that all adult patients were able to tolerate a...
CONCLUSION: Gram-negative microbes in the lower airway were related to acute exacerbation in children with asthma. These microbes and associated cytokines may play a role in exacerbating asthma in children.
CONCLUSIONS: In women, rather small amounts of regular smoking increase the risk of atopic asthma. However, for non-atopic asthma, the smoking induced risk continues for longer after quitting, especially in men. In conclusion, the effects of smoking on the risks of atopic and non-atopic asthma differ, and gender modifies these effects.
Peanut allergy is a common food allergy and the main cause of anaphylaxis among children¹ . In recent years, oral immunotherapy has emerged as a promising treatment for children with different IgE-mediated food allergies, although safety issues must be considered² . The main aim of immunotherapy is to induce tolerance or desensitization to an allergen which otherwise causes an allergic reaction. For oral immunotherapy this means ingesting the allergen in a controlled manner with gradually...
CONCLUSIONS: Our study identifies a novel regulatory T cell population, defined by CD103 expression, programmed to prevent exuberant type 2 inflammation and keep homeostasis in the respiratory tract under control. This has important therapeutic implications.
Shellfish allergy is one of the most common food allergies in the United States, accounting for approximately 25% of adulthood and 20% of childhood food allergies (FA).^(1,2) Of the different types of shellfish, shrimp is a common culprit of food allergy. The prevalence of shellfish allergy in children is substantial at 1.3% and may result in a greater prevalence in the adult population (3%) given that shellfish allergies have a low rate of spontaneous resolution.^(2,3).
CONCLUSIONS: Clinicians must be aware of the role of alexithymia and its association with maternal anxiety and previous anaphylaxis in children with FA, encouraging seeking psychological support when needed. A multidisciplinary patient-centered approach should be put in place for the effective care of FA.
CONCLUSIONS: Two BNT162b2/Pfizer doses are associated with a 48% reduction of SARS-CoV-2 incidence and a 91.3% reduction of death risk in residents from NHs facing a VOC-α outbreak. Post-vaccine RBD-IgG levels correlate with BNT162b2/Pfizer protection against SARS-CoV-2 B.1.1.7.
