University of Wroclaw, Department of Clinical Immunology, Wroclaw, Poland.

Severe asthma imposes a significant burden on patients, families and healthcare systems. Management is difficult, due to disease heterogeneity, comorbidities, complexity in care pathways and differences between national or regional healthcare systems. Better understanding of the mechanisms has enabled a stratified approach to the management of severe asthma, supporting the use of targeted treatments with biologicals. Read More

Adolescence is a challenging time for both patients and healthcare providers. Adolescent patients need to learn all the knowledge and skills required to competently and confidently self-manage their allergy and asthma. They have to negotiate the challenging transition from being children, whose medical care is supervised by their parents, to independent expert adult patients. Read More

Food allergy affects up to 10% of the population. The identification of modifiable risk factors including skin barrier dysfunction, vitamin D deficiency, microbiome, and route and timing of allergen exposure is leading to effective prevention strategies, and some of which are now included in public health guidelines. An increasing understanding of the pathophysiology has improved diagnostic options and revealed novel manifestations such as delayed anaphylaxis to mammalian meat related to sensitization to a sugar moiety triggered by tick bites.

Peanut allergy is one of the most common food allergies in children, with increasing prevalence over time. The dual-allergen exposure hypothesis now supports transcutaneous sensitization to peanut as a likely pathophysiologic mechanism for peanut allergy development. As a result, there is emerging evidence that early peanut introduction has a role in peanut allergy prevention. Read More

This Review updates the scientific evidence assessing possible causal associations of adverse events following immunisation (AEFI) compiled in the 2012 report from the Institute of Medicine and the 2014 report from the Agency for Healthcare Research and Quality. For 12 of 46 AEFI examined, a causal relationship has been established with at least one vaccine currently routinely recommended to the general USA population: anaphylaxis, arthralgia or arthritis (mild, acute, and transient, not chronic), deltoid bursitis (when vaccine is administered improperly), disseminated varicella infection (in immune deficient individuals for whom the varicella vaccine is contraindicated), encephalitis, febrile seizures, Guillain-Barré syndrome, hepatitis (in immune deficient individuals for whom the varicella vaccine is contraindicated), herpes zoster, immune thrombocytopenic purpura, meningitis, and syncope. Other than mild acute and transient arthralgia or arthritis, which is very common in adult women after rubella vaccine, these adverse reactions are rare or very rare. Read More

Epinephrine is life-saving and the only first-line medication in the management of anaphylaxis. At therapeutic doses, it acts rapidly to reverse nearly all symptoms of anaphylaxis, and stabilize mast cells. The standard approved doses administered intramuscularly in the lateral thigh have a long track record for safe and effective use, but more information is needed on epinephrine pharmacokinetics and pharmacodynamics to ensure that current dosing strategies are optimal.

Anaphylaxis is a severe and potentially life-threatening allergic reaction. Since its discovery over 100 years ago, research has led to great strides in describing pathophysiologic mechanisms of anaphylaxis; however, there is still imprecision regarding its definition and a lack of reliable, confirmatory testing. In this paper, we review definitions of anaphylaxis, highlighting studies examining the utility of the current clinical consensus definition. Read More

Food allergy has reached epidemic proportions and has become a significant source of healthcare burden. Oral food challenge, the gold standard for food allergy assessment, often is not performed because it places the patient at risk of developing anaphylaxis. However, conventional alternative food allergy tests lack a sufficient predictive value. Read More

Introduction: Previous studies in humans support the dual-allergen exposure hypothesis, and several studies in mouse models have demonstrated that cutaneous exposure to disrupted or intact skin can lead to sensitization to peanut. However, the field lacks definitive evidence that cutaneous exposure leads to peanut allergy in humans or other primates.

Methods: Peanut extract was applied to the shaved back of the neck of four male and four female African green monkeys three times per week for 4 weeks. Read More

The signaling protein MALT1 plays a key role in promoting NF-κB activation in Ag-stimulated lymphocytes. In this capacity, MALT1 has two functions, acting as a scaffolding protein and as a substrate-specific protease. MALT1 is also required for NF-κB-dependent induction of proinflammatory cytokines after FcεR1 stimulation in mast cells, implicating a role in allergy. Read More
