Can blood samples predict arthritic rheumatism?

03.02.2010
Levels of inflammatory proteins, so-called cytokines, are elevated in the blood even before the onset of arthritic rheumatism.

This means that such blood samples could be used to predict the development of the disease and thereby make it possible to prevent the pathological process, according to an article by Umeå researcher Solbritt Rantapää-Dahlqvist and her associates in the journal Arthritis and Rheumatism.

The research team analyzed blood samples from 86 individuals who donated samples to the Medical Biobank before they developed arthritic rheumatism. Of these, 69 had submitted samples at the time they were developing the disease.

Moreover, blood samples were analyzed from 256 population-based matched controls from the Medical Biobank. The concentrations of 30 different cytokines and cytokine-related factors in plasma were measured using a so-called multiplex system.

The results show that individuals that later developed arthritic rheumatism had significantly elevated levels of most cytokines and that these cytokine patterns distinguished them from the control individuals. There was a connection with several different parts of the immune defense and also with specific auto-antibodies, so-called anti-cyclic citrullinated peptide antibodies. The results indicate that several years before individuals develop symptoms of arthritic rheumatism, the immune system is activated and the process that leads to arthritic rheumatism has started.

"Our findings point to the possibility of better predicting the development of arthritic rheumatism and perhaps also of preventing the development of the disease," says Solbritt Rantapää-Dahlqvist.

Arthritic rheumatism is a chronic autoimmune disorder characterized by joint inflammation that ultimately leads to the breakdown of cartilage and bone. The disease is difficult to diagnose early since its symptoms can often be diffuse at first. However, studies have shown that it is important to diagnose and treat the disease early in order to prevent severe joint damage.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
