A bacteria only recently revealed as a major cause of ulcers and stomach cancer may help protect children from developing asthma, U.S. researchers reported Tuesday. Children ages 3 to 13 who were infected with Helicobacter pylori were 59% less likely to have asthma than those who were not infected, according to a study published in the journal Clinical Infectious Diseases. Researchers used data on more than 7,000 U.S. children from the National Health and Nutrition Examination Survey conducted from 1999 to 2000 by the National Center for Health Statistics.

Virtually all asthma attacks are triggered by allergies, according to a new study that challenges the widely held belief that the condition in adults usually has non-allergic causes. Traditionally, experts have categorized asthma as having both allergic and non-allergic forms. Allergic asthma was considered to be the most common type in children and young adults, while older people were usually thought to have non-allergic asthma.

Specialists in childhood asthma are seeing an inexplicable rise in the death rate from the disease, especially in the 10-to-14 age group. They surmise that a difference in reporting may account for some of the increase. Dr. David Tinkleman, an Atlanta asthma specialist, said it may be that some cases that were formerly diagnosed as bronchitis or pneumonia are now recognized as asthma. But other factors pushing up the death toll "really aren't known," Tinkleman said.

Some people with asthma should avoid taking the popular sleep remedy melatonin, researchers have concluded. Scientists at the National Jewish Medical and Research Center and the University of Colorado had found that blood cells make more inflammation-promoting proteins when exposed to melatonin, a hormone that regulates the body's sleep-wake cycle.

Scientists have identified two genes that contribute to the development of asthma, a discovery that could help reduce susceptibility to attacks, researchers said Monday. A new study suggests that just a subtle tweaking of the two newly identified genes could be the key to offering relief to those suffering from the respiratory ailment. "The two genes we focused on were already suspected of having something to do with asthma," said Derek Symula, a geneticist at the U.S.

High-dose injections of the drug triamcinolone can provide dramatic, and sometimes long-lasting, help for people suffering from severe, chronic asthma, New York physicians reported last week. In a study published in the New England Journal of Medicine, researchers at the Montefiore Medical Center gave the drug at various times to 12 patients with a history of hospitalization for severe asthma.

Asthma sufferers have been dying since a new drug hit the market in April, some apparently because they mistakenly believed that the long-lasting drug would immediately relieve their breathing problems. Twenty deaths have been reported to the Food and Drug Administration among users of Serevent. It is not yet clear how many are linked to misuse of the drug, but manufacturer Glaxo Inc. is warning patients and doctors to use it properly.

Asthma rates in children and adolescents tripled in some groups over a 20-year period, according to a study that adds to evidence of a puzzling growth of the disease across the country. There is no hard evidence for why rates rose from 1964 to 1983 in Rochester, Minn., study co-author Dr. Marc Silverstein said Thursday.

Merck & Co. said it won U.S. Food and Drug Administration approval of its potential blockbuster asthma drug Singulair, sending the company's shares up nearly 5%. Merck shares rose $5.94 to close at $130.63 in active trading on the New York Stock Exchange on Monday. Peak worldwide sales of Singulair could exceed $1 billion a year, putting pressure on competitors Zeneca and Abbott Laboratories, and asthma-inhaler makers such as Glaxo Wellcome, Schering-Plough Corp.
