Decade-Long Trial Confirms Benefits of Early Steroid Withdrawal for Transplant Patients

24.08.2010
A University of Cincinnati (UC) analysis of 10 years of data from local kidney transplant patients shows that patients removed from a corticosteroid regimen shortly after surgery have better graft survival rates, better survival rates and fewer cardiovascular events than patients kept on the traditional regimen of long-term steroids.

The analysis shows that, out of 904 patients transplanted at UC Health University Hospital and Christ Hospital, early corticosteroids withdrawal (ECSWD) patients had an 83.8 percent graft survival rate and a 91.7 percent patient survival rate, as compared to 68.6 percent graft survival and 83.6 percent patient survival for chronic corticosteroid (CCS) patients. UC's survival rates were numerically higher than national rates from the United Network for Organ Sharing (UNOS) registry.

Corticosteroids, in combination with other immunosuppressive drugs, have historically been prescribed to transplant patients to help suppress the body’s immune response and allow the transplanted organ to function after surgery. But they also come with an increased risk of high blood pressure, high cholesterol, weight gain, diabetes and cardiovascular disease and events.

With development of better immunosuppressive drugs, that cardiovascular risk has come to be the chief concern for transplant patients’ survival, not the loss of their new organ, explains Adele Rike Shields, PharmD, UC research assistant professor of surgery and clinical transplant pharmacist at Christ Hospital.

Four years ago, Shields says, UC researchers showed ECSWD patients had a significant reduction in cardiovascular events as opposed to CCS patients. But researchers still weren’t certain whether ECSWD patients have worse long-term graft functioning due to a risk of acute rejection of the organ.

With 10 years of data, Shields says they can now answer that question definitively.

"This is the first study with enough long-term follow-up to show that we’re not causing an increase in graft loss with early corticosteroid withdrawal,” says Shields. "We have just as good, if not better graft results and the patients’ survival is better because of their reduced cardiovascular risk.”

She presented the work last week at the International Congress of The Transplantation Society in Vancouver.

Not only does the analysis show that ECSWD patients have decreased cardiovascular events, Shields says they also have a reduced risk of malignancies not associated with immunosuppressive drugs. ECSWD patients showed a 2.2 percent rate of non-PTLD cancer, one-third the rate of malignancies in CCS patients. PTLD, or post-transplant lymphoproliferative disorder, is the name given to a group of lymphomas occurring in immunosuppressed patients.

UC transplant researchers have focused on steroid withdrawal under E. Steve Woodle, MD, chief of the division of transplant surgery. Woodle calls the data from the 10-year analysis "highly statistically significant.”

"To my knowledge, we are the first of any transplant program to demonstrate this magnitude of an effect,” he says. "We now know without a doubt that our original hypothesis generated more than 15 years ago does indeed benefit our patients. This is the final nail in the coffin for steroid based immunosuppression for our program.”

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...

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...
