Latest rheumatoid arthritis drugs compared

17.04.2008
Findings published today in the open access journal BMC Musculoskeletal Disorders shows that the latest class of drugs used to treat rheumatoid arthritis (RA) are better than standard anti-inflammatories.

RA is a chronic, debilitating, inflammatory disease of the joints, which is usually treated with anti-inflammatory drugs such as methotrexate or steroids. However, the discovery that a protein from white blood cells, known as tumour necrosis factor alpha (TNFa), caused some of the symptoms of RA, led to the development of novel drugs which block TNFa. This group of drugs, known as anti-TNFa drugs (which include infliximab, etanercept and adalimumab), are now commonly used to treat RA.

However, there have been no 'head-to-head' comparisons of the new anti-TNFa drugs in terms of safety or efficacy for the treatment of RA.

Alberto Alonso-Ruiz of the Cruces Hospital in Barakaldo, Vizcaya, Spain and colleagues at the Donostia Hospital and the University of the Basque Country, systematically searched for research on the use of anti-TNFa drugs in RA patients. They found thirteen clinical trials including over 7000 patients. The researchers then analyzed the trial results, systematically logging patient benefits and side effects for different doses of the three main anti-TNFa drugs.

Analysis of the combined results of all thirteen trials showed that anti-TNFa drugs, given at recommended doses, were better than the usual treatments, such as methotrexate, for treating RA. Patients who had previously seen little benefit from methotrexate alone showed a better response with combined anti-TNFa plus methotrexate therapy.

The team found that all three drugs were very similar in their benefits even at doses higher than those recommended by the drug manufacturer. This class of drugs, while very effective, does have a higher frequency of adverse side-effects. Patients on infliximab were most likely to drop out of a trial because of these side effects. In contrast, patients using etanercept had the lowest withdrawal rate. The researchers point out that this could be because this drug was not reported as being used at higher than recommended dosage in the trials.

“Anti-TNFa drugs such as infliximab, adalimumab and etanercept all appear to be effective in the treatment of RA” said Alonso-Ruiz. “Performing comparisons of new drugs is vital for measuring safety/efficacy relationships and monitoring adverse side-effects”

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
