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.

Study clarifies why most colic isn’t caused by cow’s milk allergy

Cow’s milk allergy rarely causes infant colic on its own, and most excessively crying infants do not have underlying allergy. A short elimination–and–rechallenge trial may help confirm CMA only when colic coexists with other allergic features.

New clinical trial shows promise for shorter TB treatment

New clinical trial results presented by TB Alliance at the Union World Conference on Lung Health show that the novel antibiotic candidate sorfequiline (TBAJ-876), a next-generation diarylquinoline, has the potential to improve tuberculosis (TB) treatment when combined with pretomanid and linezolid in a treatment regimen known as "SPaL."

Cesarean births do not raise infant allergy risk in major Japanese cohort study

In a large Japanese birth cohort, cesarean delivery was not linked to higher risks of eczema, wheezing, atopic dermatitis, or asthma in infants at one year of age. Emergency cesarean delivery was even associated with a modest reduction in eczema, suggesting that mode of birth alone may not drive early-life allergic disease.

New studies shine light on oral immunotherapy and oral food challenges in allergic children

Two new studies being presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Orlando shine a spotlight on oral immunotherapy and oral food challenges (OFCs) in children, showing that both procedures are safe for young patients and can be life-changing for families navigating food allergies.
