University of Iowa experts are warning that a commonly prescribed asthma medication combination can be deadly for certain patients. The long-acting asthma drug salmeterol used in combination with an inhaled corticosteroid can worsen asthma symptoms for those who do not need the combination, leading to life-threatening problems.

Australian researchers identified a new protein in human airway epithelial cells that regulates allergic airway inflammation. A study suggests the protein aP2 plays an essential role in both type 2 diabetes and allergic airway diseases like asthma.
The study reveals that protein aP2 is present in human epithelial cells lining the airways and its expression is increased by interleukin-4 and -13. Mice lacking aP2 exhibit reduced airway inflammation, highlighting the importance of lipids in inflammation and metabolism.
A study published in the Journal of Clinical Investigation found that a fatty acid binding protein called aP2 plays a crucial role in controlling inflammation in asthma. The research suggests that blocking aP2 function may be a novel approach for asthma treatment and other inflammatory lung diseases.

A recent study has found that children living within 75 meters of a major road are at a 50% greater risk of having had asthma symptoms in the past year. The research also showed that higher traffic volumes on roads were related to increased rates of asthma, with risk decreasing further away from the road.
Researchers discovered that prostaglandin E2 activates the pairing of EP1R with beta2AR receptors, reducing their ability to cause muscle relaxation. This may explain why some asthma treatments fail for individuals with elevated PGE2 levels.

A recent study published in PNAS found that at least two-thirds of asthma patients' pulmonary T cells are actually NKT cells, not conventional Th2 cells. This discovery may lead to the development of new treatments targeting NKT cells.
Research found a significant association between high leptin levels and asthma risk in women, but not men. The study suggests leptin may play an independent role in increasing asthma risk, rather than being linked to obesity.
Patients with asthma often view their condition as a temporary health problem, leading to inadequate treatment and poor disease control. A study found that nearly half of hospitalised asthma patients believed they only had asthma when symptoms appeared.
Researchers block C5a receptor to prevent or induce asthma-like symptoms in mice, identifying mechanism by which C5aR signaling prevents response. C5aR blockade also reduces severity of asthma-like symptoms after allergen exposure.
Researchers have found that C5aR blockade promotes Th2 sensitization upon first exposure to inhaled allergen, while during established inflammation suppresses the cardinal features of asthma. This study provides new insights into the role of the anaphylatoxin C5a receptor in type 2 immunity and asthma.
A study found that higher levels of self-esteem and problem-solving beliefs in urban, school-aged children with asthma helped counteract the negative effects of asthma and urban living. These factors were associated with fewer school absences, more participation in activities, and less missed sleep.
A new study suggests that people who are overweight or obese may have better results with the prescription pill sold as Singulair than with a type of inhaled steroid, while leaner people may have better luck with an inhaled steroid. The findings indicate that obesity may influence individuals' responses to asthma medications.
Researchers found notable increases in racial differences in asthma hospitalizations and deaths since 1980, with smaller increases seen for adults. Clinicians are urged to focus on improving treatment, prevention, and education for minorities to close the unacceptable racial gap.
A study by Dr. Jill Halterman found that children with severe asthma symptoms often exhibit behavioral problems, such as anxiety and difficulty focusing, which can impact their learning. The research suggests that addressing both asthma and behavior issues simultaneously is crucial for effective treatment.
The State Children's Health Insurance Program (SCHIP) has improved asthma care for low-income children in New York, resulting in fewer attacks and emergency room visits. SCHIP has increased access to necessary medications, preventative care, and affordable healthcare services.
Research found that some masks used in combination with pressurized metered-dose inhalers for children's asthma treatment have poor fit and high dead space volume, reducing medication effectiveness. The study suggests that better-fitting masks are crucial for effective drug delivery.
A study of 702 pregnant women found that lung function worsened in mothers with either male or female fetuses until about 30 weeks, after which improvement was noted. Mothers carrying males had better lung function throughout pregnancy by 10 percent.
Researchers discover that cellular transformation in mice and humans with asthma and chronic bronchitis leads to overproduction of mucus. A combination of two drugs, EGFR and IL-13 inhibitors, can prevent this transformation and normalize airway lining in patients.
Children with asthma living in multi-family housing are at risk due to high indoor nitrogen dioxide levels. The study found that homes with gas stoves had significantly higher concentrations than those with electric stoves, posing a greater threat to respiratory health.

Minority patients, particularly African Americans, were less likely to receive inhaled steroid medications for asthma, with usage increasing only among African American patients. Children also faced barriers to access, reflecting the need for further studies on healthcare disparities.
Scientists at The Institute for Genomic Research have sequenced the genome of Aspergillus fumigatus, a fungus that can cause human infections. The 28 Mb genome consists of 8 chromosomes with over 10,000 genes, which researchers are now searching to identify unique virulence factors.
A UCSF study found that living in lower-income areas worsens health and quality of life due to poorer air quality. Neighborhoods with high traffic flow and industrial pollution also linked to reduced lung function, while larger backyards with allergenic plants may play a role.
Researchers found that vitamin D3 supplementation can increase the responsiveness of T-cells from patients with severe asthma to steroids. The study suggests that this therapy could lead to new ways to treat people who don't respond to steroid treatment, reducing the need for heavy medication.
The study found no new or unexpected adverse events, including rare events, reported to VAERS during the first two post-licensure seasons of intranasal flu vaccine use. The researchers identified some potential risks, such as anaphylaxis and asthma exacerbation in individuals with prior asthma history.
A study found significant relationships between household endotoxin levels and diagnosed asthma, recent symptoms, and wheezing. The strongest effects were observed in adults, with lower levels of endotoxins in bedding compared to kitchen floor dust.
The updated practice parameter provides new definitions for acute, subacute, chronic, and recurrent sinusitis, as well as guidelines for diagnosis and treatment. Antibiotics should be used judiciously, and referral to an allergist/immunologist is recommended for patients with chronic or recurrent sinusitis.
Researchers at UCSD found that selectively inactivating the IKK beta gene in airway membrane-lining cells significantly reduces inflammation, mucus production, and scarring. This discovery suggests a potential targeted treatment for asthma sufferers.
