A proposal to grade the severity of early allograft dysfunction after liver transplantation

Paolo Salvalaggio, Rogerio Carballo Afonso, Guilherme Felga, Ben-Hur Ferraz-Neto

DOI: 10.1590/S1679-45082013000100006

Objective:To propose a grading system for early hepatic graft dysfunction.METHODS:A retrospective study from a single transplant center. Recipients of liver transplants from deceased donors, transplanted under the MELD system were included. Early graft dysfunction was defined by Olthoff criteria. Multiple cut-off points of post-transplant laboratory tests were used to create a grading system for early graft dysfunction. The primary outcome was 6-months grafts survival.RESULTS:The peak of aminotransferases during the first postoperative week correlated with graft loss. The recipients were divided […]

The MELD system and liver transplant waiting-list mortality in developing countries: lessons learned from São Paulo, Brazil

Paolo Salvalaggio, Rogerio Carballo Afonso, Luiz Augusto Pereira, Ben-Hur Ferraz-Neto

DOI: 10.1590/S1679-45082012000300004

Objective:The MELD system has not yet been tested as an allocation tool for liver transplantation in the developing countries. In 2006, MELD (Model for End-stage Liver Disease) was launched as a new liver allocation system in São Paulo, Brazil. This study was designed to assess the results of the new allocation policy on waiting list mortality.METHODS:The State of São Paulo liver transplant database was retrospectively reviewed from July 2003 through July 2009. Patients were divided into those who were transplanted […]

Liver transplant outcome: a comparison between high and low MELD score recipients

Andre Ibrahim David, Maria Paula Villela Coelho, Ângela Tavares Paes, Ana Kober Leite, Bianca Della Guardia, Márcio Dias de Almeida, [...]

DOI: 10.1590/S1679-45082012000100012

Objective:To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome.METHODS:Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a ± 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were [...]
