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.

Etomidate proves safer than ketamine for emergency intubations

Doctors treating seriously ill patients in an emergency setting may want to give the sedative etomidate, rather than ketamine, while placing a breathing tube, according to a randomized trial published Dec. 9 in the New England Journal of Medicine.

Early RSV infection turns maternal allergy into a powerful driver of childhood asthma

Early-life RSV infection and parental allergy interact to substantially increase childhood asthma risk, supported by population data from more than 1.5 million children and mechanistic mouse experiments. The study shows that viral infection reprograms neonatal immune responses by altering how maternally transferred allergen-specific antibodies are handled, driving long-term allergic airway disease.

Older chemical libraries yield new leads for next-generation COVID-19 antivirals

SARS‑CoV‑2, the virus that causes COVID-19, continues to mutate, with some newer strains becoming less responsive to current antiviral treatments like Paxlovid.

New rapid test distinguishes real HIV infections from vaccine-related false positives

Since the human immunodeficiency virus (HIV) was identified in 1983, roughly 91.4 million people around the world have contracted the virus and an additional 44.1 million have died from related causes.

Early-infancy infection with RSV increases the risk of developing childhood asthma

Belgian scientists from VIB and Ghent University (UGent), together with Danish collaborators, have uncovered compelling evidence that early-infancy infection with respiratory syncytial virus (RSV) significantly increases the risk of developing childhood asthma-especially in children with a family history of allergy or asthma.

Monthly biologic injection improves severe asthma control and reduces steroid use

A monthly injection has helped 90% of severe asthma patients reduce daily steroid tablets, which are associated with long-term side effects.

Comprehensive antibody map reveals how SARS-CoV-2 mutations evade immunity

Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have created the most comprehensive map to date showing how antibodies attach to the SARS-CoV-2 virus, which causes COVID-19, and how viral mutations weaken that attachment.

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."
