Highlights

New Research

• Obesity and GERD. Increased weight in women is linked to more frequent GERD symptoms, according to the Nurses' Health Study, which included 10,545 female participants. Overweight and obese women were two to three times more likely to have frequent symptoms than women of normal weight. GERD symptoms decreased nearly 40% in women whose body mass index (BMI) dropped by more than 3.5, compared to women whose BMI remained the same.
• Proton-Pump Inhibitors and Bone Fracture. Long-term use of PPIs may increase the risk of hip fractures in older adults, according to a study in the Journal of the American Medical Association. People taking high doses of PPIs for more than a year were 2.6 times as likely to fracture a hip as those who were not taking the drug. The authors suggested that the stomach acids blocked by PPIs may be needed to absorb calcium, or the drugs may interfere with the body's natural process of breaking down and rebuilding bones.
• PPIs and H2 Blockers in Children. Otherwise healthy children who take PPI inhibitors or H2 blockers may be at increased risk for intestinal and respiratory infections, according to a study of 186 children with GERD. The rate of gastroenteritis and community-acquired pneumonia significantly increased in children who were taking these medications when researchers compared the 4 months before and after enrollment in the study.

New Approval

• Proton-Pump Inhibitor Approved for Adolescents. Esomeprazole (Nexium) delayed-release capsules have been approved for use in children ages 12 - 17 for the short-term treatment of GERD. Research shows that this medication reduces heartburn symptoms in adolescents.
