Drug combination shows promise in treating hepatitis C

01.11.2004


SLU hepatologist to present findings at national conference in Boston



Interim study results indicate a certain drug combination treatment may suppress the hepatitis C virus more quickly than another. Researchers at Saint Louis University School of Medicine and six other research sites throughout the country found that combining the drug Pegasys® with ribavirin resulted in a greater reduction in hepatitis C viral levels than patients treated with Peg-Intron® and an equal dose of ribavirin.

Pegasys and Peg-Intron are types of pegylated alpha interferon--which is a longer lasting version of interferon, a naturally produced substance in the body that triggers the immune system. Combining these drugs with ribavirin enhances their efficacy and is the standard treatment for hepatitis C. "It looks as though Pegasys is more potent during the early phase of treatment, which is critical for patients with chronic hepatitis C," said Adrian M. Di Bisceglie, M.D., professor of internal medicine in Saint Louis University School of Medicine’s division of gastroenterology and hepatology, and the study’s lead investigator. "It’s critical because if patients are going to respond to treatment, it will happen during the first 12 weeks of care. Eight weeks into this trial we noticed lower viral levels in patients on the combination of Pegasys and ribavirin."


This is one of the first head-to-head studies in the United States comparing Pegasys and Peg-Intron when each are combined with equal doses of ribavirin. Pegasys is the most recent form of pegylated alpha interferon approved by the Food and Drug Administration (2002).

Di Bisceglie helped design the study and evaluate the preliminary results.

Di Bisceglie will present his findings at the 55th annual meeting of the American Association for the Study of Liver Diseases in Boston on Oct. 29.

Di Bisceglie said the ultimate goal of therapy is to clear patients of the blood-borne virus or have levels drop so low as to be undetectable. While the Pegasys results are positive, Di Bisceglie cautioned it is too soon to draw conclusions. The 12-week trial is still under way.

"Studies such as this one give us insight into how these drugs work and it might allow us to design better drugs in the future," said Dr. Di Bisceglie, one of the top liver disease experts in the world.

About 4 million Americans carry antibodies to the infection, which means they have been exposed to hepatitis C. Of that group, about 70 percent actually have the virus and will become symptomatic. The symptoms at first may be subtle: fatigue, abdominal discomfort, general malaise. While carriers ignore or misinterpret symptoms, the virus is eating away at their livers. If left undetected or untreated, chronic hepatitis C irrevocably damages the liver and a transplant may be necessary. Saint Louis University School of Medicine has one of the largest hepatitis C treatment and research programs in the country.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
