Only about 6 percent of former alcoholics and 4 percent of former illicit drug users will relapse into their addictions in any given year following an organ transplant. These results are published in the February issue of Liver Transplantation, a journal by John Wiley & Sons. The article is also available online via Wiley Interscience (http://www.interscience.wiley.com/journal/livertransplantation).
Substance abuse can lead to serious organ diseases for which transplantation is increasingly considered an acceptable treatment. Still, the transplant community remains concerned about these patients resuming their harmful behaviors once the transplant has been done.
Studies have suggested vast disparities in the prevalence of addiction relapse after transplantation, so researchers, led by Mary Amanda Dew of the University of Pittsburgh, conducted a meta-analysis of the existing literature. They sought to establish precise estimates of the rates of alcohol and drug relapse in individuals receiving liver or other solid organ transplants. They also looked for associations between relapse and many pre-transplant or psychosocial characteristics.
The researchers included 54 studies (all but four pertaining to liver recipients) that described more than 3600 former substance abusers who had received transplants. They examined the following post transplant outcomes: alcohol relapse, heavy alcohol use, illicit drug relapse, tobacco use, non adherence to immunosuppressants and nonadherence to clinic appointments.
The average rate for alcohol relapse was 5.6, or approximately 6 cases per 100 persons per year of observation (PPY). The average rate for relapse to heavy alcohol use was 2.5 per 100 PPY. The average relapse to illicit drug use was 3.7 PPY. The average relapse rates for the other studied outcomes ranged from 2 to 10 cases per 100 PPY.
