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: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
