The cause of effectiveness has been discovered for a cirrhosis treatment that has been shown to be useful in 40% of patients

28.02.2008
Scientists of the Center for Applied Medical Research (CIMA) of the University of Navarra have discovered the molecular mechanism responsible for the effectiveness of an existing treatment for primary biliary cirrhosis, which combines two substances in order to produce an effect that does not result from either substance separately.

The discovery involved the role played by the AE2 protein when the patient is treated with a combination of ursodeoxycholic acid (UDCA) together with glucocorticoids. The research results were recently published in The Journal of Clinical Investigation.

The origin of primary biliary cirrhosis (PBC)-which mostly affects middle-aged women-is still not understood. This pathology is associated with autoimmune phenomena, damage to the biliary vessels of the liver, and a reduction in the production of bile.

In Spain more than 1,000 cases are diagnosed each year, and the total number of patients worldwide is greater than 15,000. Dr. Juan Francisco Medina, Director of the Laboratory of Molecular Genetics of the CIMA, explains that in the present day the diagnosis of this disease, which is generally detected early, permits treatment with UDCA, which is effective in over half of the patients.

However, nearly 40% of PBC patients do not respond satisfactorily to monotherapy with UDCA. Therefore, we looked for a combined treatment, and discovered that the combination of UDCA with glucocorticoids was a promising treatment for this group of patients. Those who suffer from this type of cirrhosis have a deficit of AE2, which is the protein for the secretion of bicarbonate in the bile.

The possibility of more cures with fewer transplants

The originality of this recently-published research article consists in relating, for the first time, the combined treatment with UDCA and glucocorticoids with a greater quantity of bicarbonate in the bile, and an improvement of the production of bile by the liver. Specifically, experiments in animal models and cell cultures demonstrate that only the combined treatment with UDCA and glucocorticoids increases the genetic expression of the human protein AE2 in the liver.

Based on available data, Dr. Medina considers that it is advisable to use combined treatment in those cases which present a poor response to monotherapy with UDCA. He proposes the use of a corticoid such as budesonida, which has fewer side effects than cortisone and prednisone. If, for fear of side effects, we allow the disease to progress, it is very probable that the only treatment will be a transplant. On the other hand, if this treatment option is confirmed as successful, it could reduce the number of transplants required in order to save the lives of patients.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
