Long-term graft outcome of pediatric liver transplantation in Copenhagen: analysis of the first 51 cases.

BACKGROUND: Graft loss after liver transplantation remains a significant problem, especially in pediatric patients. The aim of this study was to assess our initial series of pediatric liver transplantation and to identify the risk factors that influence graft outcome. METHODS: The first 51 transplantations were analyzed retrospectively. All transplantations were stratified into three groups according to graft type (full-size, reduced-size, and living-related-donor graft). Survival data of the grafts were stratified and multivariate analysis conducted with respect to preoperative and surgical factors. RESULTS: Seventeen of all the transplants were full-size grafts and 34 technical-variant grafts (27 reduced-size grafts from cadavers and 7 living-related-donor grafts). The overall graft survival rates were 65, 62 and 53% at 1, 3 and 5 years, respectively. Twenty-three of 51 grafts (45%) were lost. Poor status of the recipients (hospitalization or intensive care unit care before surgery), a retransplanted graft, and a reduced-size graft were independent risk factors for graft failure. With experience, overall graft survival has improved significantly and the differences in graft survival between graft types have disappeared. CONCLUSIONS: To improve graft survival after pediatric liver transplantation, the timely referral of potential recipients to the transplant team and employing a meticulous technique during the operation, particularly for the technical-variant graft, are required.

[Extrapancreatic tumour-induced hypoglycaemia].

A 53-year-old non-diabetic man was admitted with hypoglycaemia, neuroglycopenic symptoms and acromegaloid facial swelling. Serum insulin concentration was suppressed, but the free concentration of insulin-like growth factor (IGF-II) was markedly elevated. CT scan demonstrated a large tumour in the liver. The histology showed a benign, solid, fibrous tumour. A hemihepatectomy was performed, and a 3.6 kg tumour was removed. Postoperatively, the blood glucose concentration and the concentration of free IGF-II returned to normal and the acromegaloid facial features disappeared.

Liver transplantation for Budd-Chiari syndrome: A European study on 248 patients from 51 centres.

BACKGROUND/AIMS: The results of liver transplantation for Budd-Chiari syndrome (BCS) are poorly known and the role and timing of the procedure are still controversial. The aim of this study was to investigate the results of transplantation for BCS, focusing on overall outcome, on prognostic factors and on the impact of the underlying disease. METHODS: An enquiry on 248 patients representing 84% of the patients transplanted for BCS in the European Liver Transplantation Registry between 1988 and 1999. RESULTS: Of the 248 patients, 70.4% were female and 29.6% male. The mean age was 35.7 years. The overall actuarial survival was 76% at 1 year, 71% at 5 years and 68% at 10 years. 77% of deaths occurred in the first 3 months: 47% were due to infection and multiple organ failure, and 18% to graft failure or hepatic artery thrombosis. Late mortality (>1 year) occurred in nine patients, due to BCS recurrence in four of them. The only pre-transplant predictors of mortality on multivariate analysis (Cox) were impaired renal function and a history of a shunt. CONCLUSIONS: Liver transplantation for BCS is an effective treatment, irrespective of the underlying cause, and should be considered before renal failure occurs.

Obesity increases mortality in liver transplantation--the Danish experience.

Obesity is increasing in the western world at an epidemic rate. The USA results in obese patients undergoing orthotopic liver transplantation (OLT) are divergent, and so far no European experience has been reported. This study was designed to determine if obesity is a risk factor for mortality and morbidity in OLT in a medium-size European center. In a retrospective study of the records of 365 consecutive patients who had undergone OLT from 1990 to 2003, 20 obese patients [body mass index (BMI) > 30 kg/m2] were identified. Their data were compared with those of the nonobese (BMI < 30 kg/m2) patients operated immediately before. There were no differences in demographic data, diagnosis leading to OLT, United Network of Organ Sharing (UNOS) classification, Child-Pugh score, or preoperative morbidity. The groups were also comparable concerning donor data, duration of operation, use of blood products, intensive care unit (ICU), or hospital admission. Mortality was, however, significantly increased in the obese group (P = 0.01). Our study clearly demonstrates an increased mortality in obese patients undergoing OLT and the relative scarcity of organs taken into account, it seems reasonable to consider obesity as a relative contraindication to OLT.

Idiopathic extensive peliosis hepatis treated with liver transplantation.

A 50-year-old Danish man, who neither had wasting disease nor was taking steroid-containing drugs, complained of abdominal distension, due to a markedly enlarged liver. Percutaneous needle biopsies were taken from the liver, and the findings gave suspicion of a neoplastic tumor. Because of reduced liver function and treatment-resistant ascites, he underwent liver transplantation without a definite preoperative diagnosis. The resected liver weighed 2900 g, and almost all of the parenchyma was destroyed and replaced by multicystic blood-filled spaces, diagnosed as extensive peliosis hepatis complicating liver cirrhosis. Extensive peliosis with liver cirrhosis is a rare condition. Only two cases, caused by contraceptives and treated by liver transplantation, are reported in the English-language literature. We could find no cause other than alcohol abuse lasting several years in this patient, and classified the present case as idiopathic extensive peliosis hepatis. Although scarce subjective findings and misleading liver biopsies made an exact diagnosis difficult, an orthotopic liver transplantation was the only treatment for such complicated peliosis hepatis.

Liver transplantation for primary sclerosing cholangitis; predictors and consequences of hepatobiliary malignancy.

BACKGROUND/AIMS: Hepatobiliary malignancies are frequently seen in primary sclerosing cholangitis (PSC) and they complicate the evaluation of patients and timing of liver transplantation. METHODS: Data from all Nordic PSC patients listed for liver transplantation during 1990-2001 were recorded prospectively. Predictors of hepatobiliary malignancy and patient survival rates have been analysed. RESULTS: Hepatobiliary malignancy was found in 52/255 (20%) patients accepted to the waiting list. Recent diagnosis of PSC, no ursodeoxycholic acid (UDCA) treatment, clinical suspicion and previous colorectal-cancer were predictors of malignancy. Among 89 patients with a strong suspicion of malignancy prior to acceptance, 35 (39%) had confirmed malignancy. A clinical suspicion had been raised in 35/52 (67%) patients with malignancy. Malignancy was found in 31/223 patients who received a liver allograft. The 1-, 3- and 5-year patient survival rates following transplantation for patients with PSC and cholangiocarcinoma were 65, 35 and 35%, respectively. CONCLUSIONS: Hepatobiliary malignancy is suspected in 1/3 of the PSC patients and found in 1/5. Although cholangiocarcinoma is regarded as a contraindication to liver transplantation (LTX), PSC patients with cholangiocarcinoma had a 35% 5-year survival following transplantation.

Relationship between postoperative erythromycin breath test and early morbidity in liver transplant recipients.

BACKGROUND: Interindividual variability in dosage requirements of the calcineurin inhibitor immunosuppressive agents cyclosporine and tacrolimus after liver transplantation may result from differences in the CYP3A activity of the liver graft. Early postoperative erythromycin breath test (ERMBT) is an in vivo measure of graft CYP3A activity. This study evaluates the usefulness of an early postoperative ERMBT in predicting early morbidity in liver transplant recipients. METHODS: In 26 liver transplant recipients, ERMBT was performed within 2 hr after transplantation. Main end points were the occurrence of cyclosporine and tacrolimus nephrotoxicity, episodes of early graft rejection, early graft function, and graft survival. RESULTS: Cyclosporine and tacrolimus nephrotoxicity were associated with low postoperative ERMBT values (mean 0.63%+/-0.25% 14C/hr vs. 1.35%+/-0.84% 14C/hr, P=0.02). No significant association between early graft rejection and ERMBT values was demonstrated. There was a significant inverse correlation between postoperative ERMBT values and the time to normalization of international normalized ratio as a measure of early graft function (r=-0.78, P<0.001). Graft loss was associated with low postoperative ERMBT values (0.21%+/-0.15% 14C/hr vs. 1.09%+/-0.72% 14C/hr, P=0.002). CONCLUSION: An early postoperative ERMBT may be useful in predicting the development of cyclosporine and tacrolimus nephrotoxicity, severe graft dysfunction, or even graft loss in liver transplant recipients when calcineurin inhibitors are administered according to protocols. Whether ERMBT results may be used to individualize dosage of calcineurin inhibitors needs to be explored.

Liver transplantation for primary sclerosing cholangitis in the Nordic countries: outcome after acceptance to the waiting list.

Primary sclerosing cholangitis (PSC) is a common indication for liver transplantation, but evaluation of patients and timing of liver transplantation remain as major problems. Data from PSC and control patients listed for liver transplantation from 1990 through 2000 in the Nordic countries were recorded prospectively. Outcomes from the waiting list and after transplantation have been recorded for both groups. For PSC patients, regression analyses have been performed to analyze predictors of outcome. A total of 255 PSC and 610 control patients were accepted on the liver transplantation waiting list from 1990 to 2000. In the PSC group, 223 patients (87%) received a first liver allograft, and 32 patients (13%) died without transplantation. The corresponding figures for the control group were 89% and 10%. For PSC patients, the 5- and 10-year survival from the time of acceptance was 68% and 58%, respectively. A higher Model for End-Stage Liver Disease score and a shorter duration of PSC predicted death on the waiting list for PSC patients. PSC is a frequent indication for liver transplantation. In our material, serum bilirubin or Model for End-Stage Liver Disease score and PSC duration are predictors of outcome including survival of the waiting list.

Fatigue and physical function after orthotopic liver transplantation.

Over the last two decades, orthotopic liver transplantation (OLT) has become an established treatment for acute and chronic liver failure. OLT impacts not only on survival, but also on health-related quality of life. This study was undertaken to describe the self-rated health of Danish liver transplant recipients, compare their self-rated health against that of the general population, and to investigate associations between sex, age, diagnosis, time after OLT, and postoperative physical function and fatigue. All adult surviving liver transplant recipients who underwent OLT in Copenhagen, Denmark, from 1990 to 1998 (n = 154) were contacted by mail and asked to complete a self-administered questionnaire. The questionnaire contained the 36-Item Short Form Health Survey, the Multidimensional Fatigue Inventory, the Hospital Anxiety and Depression Scale, and questions on marital status, education, and work. The response rate was 84.4% (n = 130). Liver transplant recipients reported poorer self-rated health than the general population in physical, but not in mental, health areas. One health aspect, fatigue, was investigated in great detail. This study found that liver transplant recipients experienced physical, rather than mental, fatigue. Diagnosis was found to be a predictor of postoperative physical function and fatigue because patients with an alcoholic or cryptogenic cirrhosis background had significantly poorer physical function and experienced more physical fatigue than liver transplant recipients with other diagnoses. Work status and survival time after OLT had significant effects on postoperative physical function and fatigue. Working and having undergone transplantation 4 to 5 years previously were associated with significantly better physical function and less physical fatigue than not working and having undergone transplantation 1 to 3 years previously. This study suggests that liver transplant recipients experience physical, rather than mental, impairment and fatigue and that diagnosis, work status, and survival time after OLT are associated with physical function and fatigue.

Fulminant hepatic failure: outcome after listing for highly urgent liver transplantation-12 years experience in the nordic countries.

Fulminant hepatic failure is a common indication for liver transplantation. Outcomes of patients listed for a highly urgent liver transplantation have been studied, with special emphasis on etiology of the liver disease, clinical condition, and ABO blood type. Data have been collected from the Nordic Liver Transplantation Registry. All Nordic patients listed for a highly urgent primary liver transplantation during a 12-year period have been included. Of the 315 patients listed for a highly urgent liver transplantation, 229 (73%) received a first liver allograft, 50 patients (16%) died without transplantation, and 36 patients (11%) were permanently withdrawn and survived. In 43% of the patients, no definite etiology of the liver failure could be established. Paracetamol intoxication was the most frequent specific indication for listing. Patients with blood type A had no significant shorter waiting time (3.8 v 6.6 days; P =.1) but a higher rate of transplantation (82% v 66%, P =.006) as compared with blood type O patients. In a multivariate analysis, paracetamol intoxication remained the single independent predictor of an outcome without transplantation. In conclusion, a high transplantation rate was observed among patients listed for a highly urgent liver transplantation because of fulminant hepatic failure. Blood type O patients had a lower chance of receiving a liver allograft. Patients with paracetamol intoxication had both a higher mortality without transplantation and a higher withdrawal rate attributable to improved condition.
