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.

Antihistamines show modest benefits for long Covid fatigue treatment

Over-the-counter antihistamines and a prescription anti-inflammatory drug both have a small benefit in reducing long Covid fatigue among people receiving care from specialist long Covid clinics, according to new findings from a large clinical trial led by UCL and UCLH.

Smoking shows no major impact on the eye microbiome in small study

A small study found no evidence that smoking causes large or consistent shifts in the ocular surface microbiome or tear proteome. The authors caution that subtle smoking-related effects cannot be ruled out, given the small cohort and the ocular surface's low-biomass, contamination-sensitive microbial niche.

New Mount Sinai center focuses on advancing personalized treatments for peanut allergy

Researchers at the Icahn School of Medicine at Mount Sinai have been awarded a five-year, $7.2 million grant from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), to establish a new Asthma and Allergic Diseases Cooperative Research Center focused on advancing personalized treatment strategies for peanut allergy.

Researchers identify a distinct subtype of eosinophilic esophagitis in children

Researchers from Ann & Robert H. Lurie Children's Hospital of Chicago identified a distinct subtype of eosinophilic esophagitis (EoE) – a chronic allergic inflammatory disorder in which the esophagus narrows, interfering with food going down properly.

Anti-lipid antibodies could improve early testing for Lyme disease

Lyme disease can be easiest to treat in its earliest stages, but current tests often miss infections during that critical window and cannot tell whether bacteria are still present or were cleared years ago.

Engineered immune cells suppress asthma symptoms in allergic mice

Genetically engineered CAR T cells expressing artificial receptor proteins are increasingly used in the clinic to boost the immune system's response against leukemias and other cancers.

Allergies show a small but significant link to later cancer risk

A systematic review and meta-analysis of 28 cohort-based studies found a weak but statistically significant association between allergic diseases and later cancer incidence. The signal was strongest in the Western Pacific region and among people with asthma, but high heterogeneity and limited subgroup evidence mean the findings require caution.

Umbilical cord proteins may explain lifelong health effects of low birth weight

Researchers have long sought to discover why babies who weigh less than expected at birth, a condition known as small for gestational age, or SGA, are at higher risk for heart, lung and metabolic diseases as adults.

Nasal viruses may drive allergic rhinitis, and ribavirin shows early promise as a targeted spray treatment

Nasal commensal viruses may worsen allergic rhinitis by activating type I IFN-linked neutrophils and NET formation. Ribavirin reduced nasal viral abundance and improved symptoms in mice and in a small phase 2 trial.

Gut fungi play key role in pediatric allergic diseases development

Two new studies jointly published in Nature: The Clinical Microbiome reveal that certain species of fungi in the gut play a key role in the development of immune dysregulation and some pediatric allergic diseases - and may be promising targets for new therapies.
