A team of researchers at McMaster University and St. Joseph's Healthcare Hamilton have successfully evaluated a new, antibody-based drug for certain patients with severe asthma.
The drug – named mepolizumab – can replace traditional, steroid-based treatments for a specific subset of patients, resulting in improved outcomes and reduced side effects.
The study and manuscript, published in the New England Journal of Medicine was led in Canada by Dr. Parameswaran Nair, staff respirologist, Firestone Institute for Respiratory Health at St. Joseph's Healthcare Hamilton and professor of respirology at the Michael G. DeGroote School of Medicine at McMaster University. Dr. Nair and his colleagues recruited the largest number of participants for this global study.
"This new drug is the only therapy that has been proven to be effective in well-established clinical trials to help reduce doses of steroid-based treatments such as prednisone for those with severe asthma," said Dr. Nair, adding that the paper reconfirms the team's observation published in the New England Journal of Medicine in 2009.
Patients with severe asthma often require high doses of steroid-based treatments that can significantly impair their quality of life. These high doses can cause debilitating side effects including mood swings, diabetes, bone loss, skin bruising, cataracts and hypertension.
Previous research at the Hamilton institutions has identified specific types of patient with severe asthma have an overabundance of a particular type of white blood cell (eosinophils) present in their sputum. These patients often suffer from the most severe asthma symptoms and can only be treated through steroid-based medications such as prednisone.
"This is an exciting example of personalized medicine for asthma," said Nair. "This discovery now tells us by using a simple blood or sputum eosinophil count, we can identify which asthma patients can benefit from this new treatment.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
