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 maps how birth order tracks disease risk across 10 million siblings

Researchers analyzing claims from more than 10 million siblings linked first-born status to higher odds of several neurodevelopmental and allergic diagnoses, while second-born status tracked with substance abuse and gastrointestinal conditions. The observational study identified 150 significant birth-order associations across the phenome, but claims data and residual confounding prevent causal conclusions.

Study questions antihistamine use for managing eczema symptoms

Adding oral antihistamines to existing eczema treatments is unlikely to lead to clinically important reductions in eczema and itch severity, and may not reduce sleep disturbance or flare-ups, finds a review of the latest trial evidence published by The BMJ today.

NIH awards $2.4 million to study how maternal viral infections reprogram fetal immune development

The National Institute of Allergy and Infectious Diseases of the National Institutes of Health has awarded a new, five-year $2.4 million R01 grant to Dr. Jiahui Ding, assistant professor of obstetrics and gynecology at the Wayne State University School of Medicine's C.S. Mott Center for Human Growth and Development, to support research that aims to uncover how viral infections during pregnancy reprogram the developing immune system of the fetus, influencing susceptibility to infectious diseases throughout life.

Dengue virus infects memory B cells to evade immune defenses

Researchers at the University of Vermont Robert Larner, M.D. College of Medicine and Upstate Medical University in Syracuse, NY, have discovered that dengue virus can infect and replicate inside memory B cells, immune cells traditionally understood to help protect the body from infection.

Oral drug candidate blocks transmission of measles-like disease in ferrets

A new oral antiviral drug candidate administered either before or after direct contact or airborne exposure to canine distemper virus, which causes measles-like disease in ferrets, blocks transmission of the virus and reduces clinical symptoms, according to a study published in the journal Nature Microbiology by researchers in the Center for Translational Antiviral Research (CTAR) at Georgia State University.
