However, a randomized clinic trial conducted by the American Lung Association's Asthma Clinical Group found that the addition of lansoprazole does not improve asthma symptoms or the control of asthma in children and may increase the risk for upper respiratory infections and other adverse events. Results of the study appear in the January 25 issue of JAMA.
Lansoprazole belongs to a class of drugs called proton pump inhibitors (PPIs) that reduce acid in the stomach. Use of these drugs, including for the treatment of asthma symptoms, has risen dramatically in children over the last decade.
"The data were very clear. Lansoprazole did not improve asthma symptoms in children as compared to a placebo, and there is no evidence to support prescribing these drugs to treat asthma in children," said Janet Holbrook, PhD, corresponding author of the study and associate professor in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health. "In our study, children taking lansoprazole showed an increased risk for respiratory infection, sore throats and bronchitis." The Bloomberg School's Center for Clinical Trials served as data coordinating center for the research team.
For the study, researchers from 18 trial sites studied 306 children ages 6 to 17 years. All study participants had inadequately controlled asthma despite taking inhaled corticosteroids but did not have the typical symptoms of GER. Approximately 40 percent of participants were identified as having GER based on diagnostic testing. The participants were randomly selected to receive either a daily dose of lansoprazole or a placebo pill over a 24-week period in addition to their inhaled steroid therapy.
The researchers found no significant differences in severity of asthma symptoms or overall lung function between the group taking lansoprazole and the group receiving the placebo, including in the children positively identified as having GER. An earlier separate study of adults conducted by the same research team showed similar results.
The study was funded by the National Heart, Lung, and Blood Institute (NHLBI), which is part of the National Institutes of Health.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
