Allergies

The term allergy encompasses a wide range of conditions; it is not a disease in itself. The term allergy – medically termed hypersensitivity, signifies an exaggerated reaction to foreign substances.

Old Friends Hypothesis

The "old friends" hypothesis was proposed by Graham Rook in 2003 as an alternative to or refinement of the hygiene hypothesis, originally brought forward by Strachan in 1989 as an explanation for the rise in allergic disease.

Skin microbiome changes may predict infant eczema and food allergies

The first clues that a baby may develop eczema or food allergies could be hiding in the microscopic organisms living on their skin, according to a study led by researchers in Washington State University's College of Veterinary Medicine.

Standard pediatric blood pressure thresholds miss early trauma warning signs

Blood pressure thresholds commonly used to identify dangerously unstable vital signs in children may not signal trouble soon enough after a traumatic injury, according to a national study of more than 230,000 pediatric trauma patients.

New biologic therapy significantly reduces COPD flare-ups in trials

Two international clinical trials led in part by researchers at the University of Pittsburgh School of Medicine found that the investigational biologic therapy tozorakimab significantly reduced chronic obstructive pulmonary disease (COPD) flare-ups among patients already receiving standard treatment for the disease compared to patients only receiving standard treatment.

Genetic marker links popular seizure drug to life-threatening reaction

A genetic marker already used to flag risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine - and it is missing from the gene panels clinicians order before prescribing the drug, Vanderbilt Health-led researchers report Sept. 2 in JAMA Network Open.

Nanoparticle flu vaccine design could pave way for broader protection

Influenza viruses constantly shapeshift to evade recognition by the immune system. This shapeshifting occurs in critical proteins like hemagglutinin (HA), which controls how the virus attaches to human cells before entering them.

Children's Colorado launches new program to expand treatment options for children with food allergies

Children's Hospital Colorado's Allergy and Immunology Center today launched its Sublingual Immunotherapy Program at its Anschutz Medical Campus in Aurora, expanding treatment options for children with certain food allergies.

Tick-borne alpha-gal syndrome poses potential risks during blood transfusions

A new multi-institute study led by researchers at Dartmouth Health and Geisel School of Medicine at Dartmouth suggests that alpha-gal syndrome, the tick-borne disease that can result in a chronic allergy to meat and animal byproducts, also may complicate certain patients' ability to safely receive a blood plasma or platelet transfusion.
