Organ donation and transplantation from poisoned donors

Extended criteria for organ acceptance. Strategies for achieving organ safety and for increasing organ pool

The terms extended donor or expanded donor mean changes in donor acceptability criteria. In almost all cases, the negative connotations of these terms cannot be justified. Factors considered to affect donor or organ acceptability have changed with time, after showing that they did not negatively affect graft or patient survival per se or when the adequate measures had been adopted. There is no age limit to be an organ donor. Kidney and liver transplantation from donors older than 65 years can have excellent graft and patient actuarial survival and graft function. Using these donors can be from an epidemiological point of view the most important factor to esablish the final number of cadaveric liver and kidney transplantations. Organs with broad structural parenchyma lesion with preserved functional reserve and organs with reversible functional impairment can be safely transplanted. Bacterial and fungal donor infection with the adequate antibiotic treatment of donor and/or recipient prevents infection in the latter. The organs, including the liver, from donors with infection by the hepatitis B and C viruses can be safely transplanted to recipients with infection by the same viruses, respectively. Poisoned donors and non-heart-beating donors, grafts from transplant recipients, reuse of grafts, domino transplant and splitting of one liver for two recipients can be an important and safe source of organs for transplantation.

Ecstasy-induced brain death and acute hepatocellular failure: multiorgan donor and liver transplantation

BACKGROUND

Ecstasy is a neurotoxic and hepatotoxic drug. Brain edema and fulminant hepatic failure are two of the most serious complications associated with the consumption of ecstasy. Acute ecstasy intoxication can transform a patient into an organ donor or a hepatic graft recipient.

MATERIALS AND METHODS

In the last 5 years in our centers, we have had two multiorgan donors who died from ecstasy-induced brain edema and three patients who required urgent orthotopic liver transplantation for treatment of severe acute hepatocellular failure induced by this drug. We performed eight transplantations using the organs of these two brain-dead donors: one heart, one bipulmonary, three kidneys, one kidney-pancreas, and two livers.

RESULTS

Toxicity caused by ecstasy was not observed in any of the eight patients who underwent transplantation. The clinical state and the graft function of the heart, two liver, renopancreatic, and three kidney recipients were normal for a follow-up period that ranged between 7 months and 4.5 years. The lung recipient died from multiorgan failure secondary to bilateral pneumonia 5 days after the transplantation, and one of the kidney transplant patients died as a result of intestinal lymphoma 6 months after transplantation. The three liver transplantations in the three patients with ecstasy-induced fulminant hepatic failure were performed successfully using orthotopic transplantation. These three recipients are asymptomatic and have normal-functioning hepatic grafts after follow-up of 3.5 years, 15 months, and 11 months, respectively.

CONCLUSIONS

The thoracic and abdominal organs of people dying from ecstasy intoxication can be viable for transplantation. The short- and medium-term survival of the graft and of the recipient have been similar to that of other organ donors. Urgent liver transplantation is an effective therapeutic option in patients with ecstasy-induced acute hepatocellular failure.
