Newer Rheumatoid Arthritis Drugs: Harmful On The Liver?

27.10.2003


Results of 41,885 Patient Analysis Announced at the American College of Rheumatology Annual Scientific Meeting



The disease modifying anti-rheumatic arthritis drug (DMARD), leflunomide does not have a higher risk of liver side effects than the traditional drug, but other newer DMARDs may, according to investigators at the Research Institute of the McGill University Health Center (MUHC). Their findings, presented today at the American College of Rheumatology Annual Scientific Meeting, show that this drug, leflunomide, has a similar effect on the liver as the traditional drug, methotrexate, and that newer biologic DMARDs may have greater risks.

“We decided to look specifically at the effect of leflunomide on the liver because of recent spontaneous reports with this drug,” said MUHC Director of Clinical Epidemiology Dr. Samy Suissa and lead investigator of the study. “We found that patients taking leflunomide had the same risk of hepatic events than patients taking methotrexate.”
Rheumatoid arthritis, a chronic inflammatory disease of joints and other internal organs, affects one out of 100 Canadians, and affects two million Americans. It leads to swelling, pain, stiffness, and possible loss of function and deformity of these joints. Treatments for rheumatoid arthritis are increasingly effective in slowing down this debilitating disease but their side effects can cause other health problems.


Dr. Suissa, also a professor at McGill University, and colleagues looked at data obtained from two large American health insurance companies that included 41,885 DMARD users. The DMARDs dispensed included leflunomide, the newer biologic DMARDs, methotrexate and other traditional DMARDs. Their study shows that the risk of serious hepatic events was significantly increased only with biological modifier DMARDs, not with leflunomide or other DMARDs.

“Evaluative studies such as these are extremely important in determining the best treatment options for patients while avoiding harm,” said Suissa. “Our findings suggest the hepatic side effects observed with the biologic DMARDs must be investigated further.”

The study was supported by Aventis, the makers of leflunomide.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
