Allogenic hematopoietic stem cell transplantation (HSCT) is the optimal treatment of hematologic diseases and various malignancies. Development of allergic disease in a transplant patient has been reported.
Despite significant advances in understanding the epigenetic landscape of chronic rhinosinusitis (CRS), the specific microRNAs (miRNAs) with a causal role in CRS pathogenesis remain unclear.
Severe asthma and moderate-to-severe atopic dermatitis can significantly impact the lives of children and adolescents. However, real-world data on pediatric patients’ perceptions of their medication are limited.
Food insecurity is a growing concern, that is currently estimated to affect 1 in 4 Canadian children. Due to the additional effort required for management and the disproportionate cost of allergy friendly food...
Evidence linking hereditary angioedema (HAE) to the potential association of developing other comorbidities, and how it is affected by HAE treatment is needed. The objective of this study is to identify comorb...
Hereditary angioedema (HAE) is a rare, potentially life-threatening condition that requires accessible and reliable information. YouTube has emerged as a significant source of health-related content, offering ...
An epidemiological association among asthma, blood eosinophil level and chronic rhinosinusitis (CRS) is well established, but whether consistent genetic relationships exist, and whether this reflects a shared ...
The goal of on-demand treatment for hereditary angioedema attacks is to halt attack progression to minimize morbidity and mortality. Four on-demand treatments have been approved thus far (ecallantide, icatiban...
Food oral immunotherapy (OIT) is an option for the treatment of immunoglobin E (IgE)‐mediated food allergy that involves administering gradually increasing doses of an allergenic food over time (under medical ...
Contact allergens typically trigger localised reactions, but systemic Type I hypersensitivity from skin contact reactions are rare.
When a member of a family has been diagnosed with hereditary angioedema (HAE) before a child is born, the question of early diagnosis arises. Indeed, the first attacks may occur at birth. Early diagnosis is co...
Asthma is one of the most common respiratory disorders in Canada, however, many Canadians with asthma remain poorly controlled. In most patients, control can be achieved through appropriate therapy, including:...
Our previous 2007 study reported a 19.4% rate of biphasic anaphylaxis in Kingston, Ontario. Since then, few updates have been published regarding the etiology and risk factors of biphasic anaphylaxis. This stu...
The field of medicine is constantly changing and, as healthcare providers, we are fortunate to be practicing in a time when patients are living longer and novel therapeutic options continue to evolve. However,...
Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions (HSRs) with varying mechanisms and clinical presentations. This type of adverse drug reaction (ADR) not only affects p...
Until recently, immediate emergency department (ED) transfer after food-related anaphylactic reactions was recommended regardless of symptom resolution following use of an epinephrine autoinjector (EAI). We ev...
The incidence of allergic diseases has been increasing in Japan. In particular, a serious decline in the age of onset of allergic rhinitis has been observed. Passive smoking from parental smoking has a signifi...
Nasal allergen provocation tests are an important part of the diagnostics of allergic diseases triggered by environmental factors. Recently, increased attention has been paid to the potential use of this metho...
Primary immunodeficiencies (PID), now often referred to as inborn errors of immunity (IEI), are a large heterogeneous group of disorders that result from deficiencies in immune system development and/or functi...
Immunoglobulin replacement therapy (IgRT) is the current standard of care for primary antibody deficiency patients (majority of all primary immunodeficiency (PID) diseases), with growing real-world evidence su...
Food allergy is defined as an adverse immunologic response to a food. Immunoglobulin E (IgE)-mediated reactions to foods are associated with a broad range of signs and symptoms that may involve any of the foll...
Allergic rhinitis (AR) is a common disorder that is strongly linked to asthma and conjunctivitis. Classic symptoms include nasal congestion, nasal itch, rhinorrhea and sneezing. A thorough history, physical ex...
Many clinicians feel uncomfortable with de-labelling penicillin allergies despite ample safety data. Point of care tools effectively support providers with de-labelling. This study’s objective was to increase ...
Eosinophilic esophagitis (EoE) is an atopic condition of the esophagus that has become increasingly recognized. Diagnosis of the disorder is dependent on the patient’s clinical manifestations and must be confi...
Food allergy typically begins early in life and persists as a lifelong condition. Delayed introduction of allergenic foods followed by years of hesitancy to introduce these foods early may have contributed to ...
Non-immunoglobulin E (IgE)-mediated food allergies are characterized by delayed gastrointestinal (GI) manifestations that occur after exposure to an inciting food protein; they include food protein-induced all...
The body has a collection of physical barriers to prevent infection, but once these are overcome, we rely on our immune systems to protect us against a wide variety of infections. The complex mechanisms throug...
Eosinophilic gastrointestinal diseases (EGIDs) are chronic immune-mediated inflammatory disorders characterized by gastrointestinal symptoms and eosinophilic inflammation in specific regions of the gastrointes...
Oral food challenge (OFC) is the gold standard for diagnosing food allergies (FAs) but carries the risk of anaphylactic reaction. Stepwise OFC, starting with a low dose of allergen and progressing to medium an...
Allergen immunotherapy (AIT) is a potentially disease-modifying therapy that is effective for the treatment of allergic rhinitis/conjunctivitis, allergic asthma and stinging insect hypersensitivity. The decisi...
Angioedema can occur in the absence of urticaria and can be broadly divided into three main categories: mast cell-mediated (e.g., histamine), non-mast-cell-mediated (bradykinin-induced) and idiopathic angioede...
Urticaria (hives) is a common disorder that may be associated with angioedema (swelling that occurs beneath the skin). It is generally classified as acute or chronic, and chronic urticaria is further classifie...
Atopic dermatitis (AD) is a common, chronic skin disorder that can significantly impact the quality of life (QoL) of affected individuals as well as their families. Although the pathogenesis of the disorder is...
