Study identifies factors which predict alcohol use after liver transplantation

19.08.2010
Patients who receive a liver transplant due to alcoholic liver disease need to demonstrate periods of abstinence and often attend addiction treatment before transplantation.

However, alcohol use disorders can recur, as can other diseases requiring transplantation, and thus alcohol use after liver transplantation is not uncommon.

A new study published today in the American Journal of Transplantation reveals that those at highest risk to drink alcohol post transplant, especially in patterns that will damage their health, can be identified potentially preventing relapse.

Researchers led by Andrea DiMartini, MD, of the University of Pittsburgh Medical Center, collected data on alcohol consumption following liver transplantation for alcoholic liver disease in 208 patients transplanted between May 1998 to August 2004.

Alcohol relapse rates following liver transplantation are low, especially when compared to the general population. Of the 208 patients, 54% had no reported alcohol use post surgery.

However, among the remaining patients who did drink alcohol again, certain patterns emerged. Two patterns show early onset of alcohol use, one moderate and one accelerating to heavy use. These patterns show that for some patients, resumption occurs early following transplantation and recipients can quickly lose control over their drinking. For others, moderate to heavy alcohol use can begin years post surgery, showing that clinical monitoring for alcohol use should extend well beyond the first one to two years post-LTX.

The researchers found that the length of sobriety prior to surgery is the most powerful predictor of return to alcohol use, e.g. shorter sobriety conferring higher risk. Additionally, stresses immediately following surgery would increase the risk of alcohol use. Those more likely to drink were experiencing more problems overall, were more stressed, reported worse health, and had more pain and less energy.

"Our findings will aid clinicians in early monitoring and identification of patients at risk for alcohol use," DiMartini notes. "With improved methods to identify those at high risk, and effective treatments for alcohol use disorders, we can keep the relapse rates low and get patients into proper treatment before they injure their health."

About the Journal

American Journal of Transplantation reflects the field and is an agent for advancing it through critical reviews and news features, consensus documents and guidelines. The journal is directed at scientists and clinicians in transplantation but also at those in other fields who wish to follow transplantation. The scope is the international discipline of transplantation. This includes organ and tissue donation and preservation; tissue injury, repair, inflammation, and aging; immune recognition, regulation, effector mechanisms, and opportunities for induction of tolerance; histocompatibility; drugs and pharmacology relevant to transplantation; graft survival and prevention of graft dysfunction and failure; clinical trials and population analyses; transplant complications; xenotransplantation; and ethical and societal issues. The sciences includes relevant aspects of cell biology, medicine, surgery, pediatrics, and infectious diseases. The journal includes thoracic transplantation (heart, lung), abdominal transplantation (kidney, liver, pancreas, islets), transplantation of tissues and related topics.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
