Guest guest Posted October 19, 2006 Report Share Posted October 19, 2006 Hi Mike; My understanding is that the lower the MELD at transplant, the better the outcome (survival), as indicated in this study from the UK, which supports results of 4 similar studies in the US: Liver Transpl. 2004 Jul;10(7):903-7. Comment in: Liver Transpl. 2004 Jul;10(7):908-10. Pretransplant MELD score and post liver transplantation survival in the UK and Ireland.

It has been shown that the model for end-stage liver disease (MELD) score is an accurate predictor of survival in patients with liver disease without transplantation. Four recent studies carried out in the United States have demonstrated that the MELD score obtained immediately prior to transplantation is also associated with post- transplant patient survival. Our aim was to evaluate how accurately the MELD score predicts 90-day post-transplant survival in adult patients with chronic liver disease in the UK and Ireland. The UK and Ireland Liver Transplant Audit has data on all liver transplants since 1994. We studied survival of 3838 adult patients after first elective liver transplantation according to United Network for Organ Sharing categories of their MELD scores (< or = 10, 11-18, 19-24, 25- 35, > or =36). The overall survival at 90-days was 90.2%. The 90-day survival varied according to the United Network for Organ Sharing MELD categories (92.6%, 91.9%, 89.7%, 89.7%, and 70.8%, respectively; P < 0.01). Therefore, only those patients with a MELD score of 36 or higher (3% of the patients) had a survival that was markedly lower than the rest. As a consequence, the ability of the MELD score to discriminate between patients who were dead or alive was poor (c-statistic 0.58). Re-estimating the coefficients in the MELD regression model, even allowing for nonlinear relationships, did not improve its discriminatory ability. In conclusion, in the UK and Ireland the MELD score is significantly associated with post- transplant survival, but its predictive ability is poor. These results are in agreement with results found in the United States. Therefore, the most appropriate system to support patient selection for transplantation will be one that combines a pretransplant survival model (e.g., MELD score) with a properly developed post- transplant survival model.

This also seems to be true for PSC patients ... a lower MELD score is a predictor of survival following transplantation for PSC patients: Scand J Gastroenterol. 2003 Nov;38(11):1176-83.

BACKGROUND: Primary sclerosing cholangitis (PSC) is the most common indication for liver transplantation in the Nordic countries. Because these patients are difficult to evaluate with regard to timing of liver transplantation, it is important to establish predictors of post-transplant survival. METHODS: Data from two groups of patients receiving liver allografts during 1982-2001 were recorded: (a) PSC patients and ( comparison patients. Outcome following transplantation has been recorded for all patients. Regression analyses have been performed for PSC patients to analyse predictors of patient and graft survival. RESULTS: A total of 245 PSC and 618 comparison patients received a first liver allograft in the period 1982 until the end of the study. The overall 1-, 3- and 5- year patient survival rates were 82%, 77% and 75%, and 80%, 77% and 74% in the PSC group and comparison group, respectively. Survival following transplantation has increased with time in both the PSC and the comparison group. Recent year of transplantation, no previous hepatobiliary surgery and a lower MELD score were predictors of survival following transplantation for PSC patients. PSC patients had a higher rate of re-transplantations (13% versus 8%, P = 0.01). Predictors of re-transplantation in PSC patients were an episode of early rejection and vascular thrombosis. CONCLUSION: In PSC patients, year of transplantation, previous hepatobiliary surgery and MELD score are predictors of survival following transplantation and these patients are more frequently in need of re- transplantation compared to the comparison group.

Guest guest Posted October 20, 2006 Report Share Posted October 20, 2006 Chew on this for a while. With a MELD score of less than 15, a patient is probably feeling pretty good, so the first year after transplant with the subsequent healing and rehabilitation, there is significant discomfort, compared to the way the patient FELT before the transplant. But when you hear stories of patients who present with MELDs in the 20s, they probably FEEL pretty miserable. So transplant provides a significant improvement of quality of life. The level of discomfort and the numbers in bloodwork might indicate that both the patient with a 15 and the patient with the 23 are in IDENTICAL physical condition but the 23 reports that he/she FEELS much better than the 15. Maybe this is what the doctor is referring to. I've also read stories where in living donor transplant, the PSC patient wakes up from surgery and reports actually feeling better than immediately before surgery and the donor is the one who suffers. Who's in more pain? Who's blood counts are worse. Neither. It's just that the donor was healthy and feeling good before the surgery and the doctor made a 20 inch incision and removed a lobe of liver and the PSC patient was fatigued, septic, depressed, basically dying and the doctor puts in a healthy chunk of liver which immediately starts removing toxins and being a better contributor to the conversion of food to energy. Does this help? - ERCP 9-02, PSC 12-02, Gallbladder 2-03, right tib/fib fx w/ rod placement 1-05(this is for another support group), ERCP 4-05, UC 5-06 > > than the people with high scores.

Guest guest Posted October 20, 2006 Report Share Posted October 20, 2006 As the article that Barb sent in highlights, people who are transplanted at less that 15 MELD do worse than people with MELD <15 who aren't transplanted (on average). They probably do as well or better than people with a MELD over 15 who are transplanted (although the article doesn't comment on this). I guess this shows the importance of saying what you're comparing to when you make a comparison.... sort of like the companies that say their product is 20% better, but don't say what it's better than! athan Quote Link to comment Share on other sites More sharing options...
