A study by Massachusetts General Hospital investigators found that patients believed allergic to penicillin have significantly increased risks of contracting MRSA and C. difficile. The increased risk can be attributed to the use of broad-spectrum alternative antibiotics, which contribute to antibiotic resistance and virulent infections.
A recent study published in The BMJ found that patients with a recorded penicillin allergy are at an increased risk of developing MRSA and C difficile infections. The risk is largely due to the use of broad-spectrum antibiotics as alternatives to penicillin, which may be fueling the development of drug-resistant bacteria.
Researchers found that children with multiple allergies are nine times more likely to develop eosinophilic esophagitis. The study suggests a common underlying biological cause among these allergies and implies that early treatment of one allergy may prevent later disorders.

A new study published in The BMJ reviewed data from 37 trials on infant hydrolysed milk formula and found no statistically significant reduction in the risk of conditions such as eczema, wheezing, or food allergies. The research also revealed conflicts of interest in many studies due to financial links with baby formula manufacturers.
A systematic review and meta-analysis of 37 intervention trials found no consistent evidence that partially or extensively hydrolysed milk formula prevents allergic or autoimmune diseases in infants. Current guidelines recommending these formulas may be misguided, experts say.
A study by McMaster University found that teenagers with food allergies are more likely to have depression, anxiety, or attention-deficit hyperactivity disorder (ADHD) compared to their peers without allergies. Mothers of teens with food allergies are also more likely to report these emotional and behavioral problems.

Researchers found that mice and humans lacking functional CARD9 cannot recruit neutrophils to control Candida infection in the CNS, highlighting the critical role of CARD9 in promoting antifungal immunity.
A new study found no significant difference in allergies between children who were breastfed and those formula-fed. The study examined 194 patients aged 4-18 years old with hay fever and similar numbers of kids with asthma, eczema, and food allergy.
A new study found that most seasonal allergy sufferers take over-the-counter medications rather than prescribed treatments, despite being more satisfied with these options. The survey also revealed children are more likely to receive care from allergists and be on prescription medication compared to adults.
A Mayo Clinic study found stepping down daily asthma medicines can be done safely and at less cost for patients with stable asthma. Patients who stepped down their medicines saved an average of $34 per month compared to those who maintained the same level, without increased costs or reduced quality of life.
