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.

A 30-day benznidazole regimen offers safer Chagas disease treatment option

A 30-day course of benznidazole taken once a day could offer people with chronic Trypanosoma cruzi infection a safer and more practical option than the current standard treatment, taken twice a day for 60 days.

Sensory neurons remember past allergens to trigger future allergic reactions

Mass General Brigham researchers found that sensory neurons retain a 'memory' of allergens that may help explain why allergies develop over time.

SARS-CoV-2 protein ORF8 drives macrophage infection and lung inflammation

In the sickest COVID-19 patients, the SARS-CoV-2 virus doesn't just cause severe damage by directly infecting airway cells.

Can maternal diet prevent infant food allergy? A large trial puts eggs and peanuts to the test

A large Australian randomized trial of 2,137 pregnant women tested whether substantially increasing egg and peanut consumption during pregnancy and breastfeeding could prevent food allergy in infants with a strong family history of allergic disease. Higher maternal intake did not significantly reduce IgE-mediated egg or peanut allergy at 1 year, although the lower-than-expected allergy rate limited statistical power and the results could not exclude a clinically important benefit.

Weill Cornell Medicine receives $17.4 million grant to shorten tuberculosis treatment

Researchers at Weill Cornell Medicine have received a $17.4 million, five-year grant from the National Institute of Allergy and Infectious Diseases to discover new approaches to shorten tuberculosis (TB) treatment, potentially making it easier for patients to complete therapy.

Immunotherapy combined with BCG vaccine drastically lowers tuberculosis relapse risk

Tuberculosis (TB) remains one of the world's leading causes of death, and preventing post-treatment relapse continues to be a major worldwide health challenge.

Silica and dust mites combine to worsen asthma inflammation

Inflammation associated with asthma and other allergic airway diseases can be significantly worsened by exposure to both house dust mite allergens and crystalline silica, according to a new study published in the journal Allergy.

Tirzepatide vs semaglutide for asthma: the difference was smaller than researchers expected

In a US multicenter electronic health record study, researchers compared tirzepatide with semaglutide in adults with asthma and type 2 diabetes, matching 8,176 patients in each treatment group. Asthma exacerbation risk was similar between treatments, while tirzepatide was associated with a lower likelihood of receiving a short-acting beta-agonist prescription.

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.
