Capsule summary: In a birth cohort study, early colonization of the upper airway with Staphylococcus aureus and detection of rhinoviruses and Moraxella catarrhalis during illnesses were associated with subsequent childhood asthma.

Very-early-onset inflammatory bowel disease (VEOIBD) is a chronic inflammatory disease of the gastrointestinal tract occurring during infancy or early childhood. NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome has emerged as...

Acute respiratory viral infections are a major cause of respiratory morbidity and mortality, especially in patients with preexisting lung diseases such as asthma. Toll-like receptors are critical in the early detection of viruses and in activating...

We report on patients with STAT3 loss-of-function (LOF) mutations who developed lupus-like autoimmunity. Immune dysregulation seen in STAT3 LOF patients suggests a susceptibility to systemic autoimmunity with important implications in monitoring and...

The novel coronavirus SARS-CoV-2 (COVID-19) was recognized in December 2019 as a cause of severe pneumonia and has now led to a global pandemic.1 Respiratory illnesses caused by COVID-19 cover a range of severity. The identification of risk and...

Asthma is a heterogeneous disease characterized by distinct phenotypes with associated microbial dysbiosis.

COVID patients in ICU present a high mortality rate and immunoprofiling reveals heterogeneous IFN-α2 production with about 20% of critically-ill patients unable to produce IFN-α2, highlighting the immune response heterogeneity and opening avenues...

Microbiome analysis of sputum reveals distinct endotypes of COPD with different inflammatory profiles and long term survival.

Primary immunodeficiency diseases (PIDDs) are clinically and genetically heterogeneous disorders thus far associated with mutations in more than 300 genes. The clinical phenotypes derived from distinct genotypes can overlap. Genetic etiology can be...

Smell dysfunction has a significant impact on quality of life (QOL), potentially leading to food poisoning, a reduction in appetite and eventually malnutrition, immunity reduction, and worsening of medical illness.1

Deep-immunophenotyping of the circulatory T cell compartment using mass cytometry and unsupervised clustering analysis, identifies phenotypic and functional differences in patients with atopic dermatitis (AD) and psoriasis, highlighting the stronger...

Peanut sublingual immunotherapy (SLIT) for 1 year has been shown to induce modest clinical desensitization in allergic children. Studies of oral immunotherapy, epicutaneous immunotherapy, and SLIT have suggested additional benefit with extended...

Cat allergy in human subjects is usually caused by the major cat allergen Fel d 1 and is found in approximately 10% of the Western population. Currently, there is no efficient and safe therapy for cat allergy available. Allergic patients usually...

Despite guidelines recommending avoidance of peanuts during infancy in the United Kingdom (UK), Australia, and, until recently, North America, peanut allergy (PA) continues to increase in these countries.

Asthma is a highly heterogeneous disease, often manifesting with wheeze, dyspnea, chest tightness, and cough as prominent symptoms. The eliciting factors, natural history, underlying molecular biology, and clinical management of asthma vary highly...
