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.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
