Radiographic features of liver allograft rejection

The radiographic features of 19 transplanted patients with failure of the liver allograft were evaluated. These features were: poor filling, stretching, attenuation of intrahepatic biliary ducts documented by T-tube cholangiogram, attenuation of branches of the hepatic artery seen on angiogram as well as a decrease of blood flow through the liver seen on angiogram and nuclear medicine dynamic scintigram. These findings were secondary to swelling of the transplanted liver and were not specific for rejection; they may also be present in hepatic infarction or infection

Budd-Chiari syndrome recurring in a transplanted liver

A patient with Budd-Chiari syndrome who underwent orthotopic liver transplantation and developed recurrent disease is described. The immediate postoperative period was complicated by multiple thrombotic episodes, followed by a period of apparent remission associated with the initiation of coumadin and persantine therapy. After discontinuation of such antithrombotic therapy in order to biopsy the liver, the patient experienced another series of clinically overt vascular thromboses and ultimately died of sepsis 15 mo posttransplantation after a prolonged and complicated terminal hospital course. At autopsy, recurrent Budd-Chiari syndrome as well as thromboses in numerous other organs was demonstrated. © 1983

Disease gravity and urgency of need as guidelines for liver allocation

One thousand one hundred and twenty-eight candidates for liver transplantation were stratified into five urgency-of-need categories by the United Network for Organ Sharing (UNOS) criteria. Most patients of low-risk UNOS 1 status remained alive after 1 yr without transplantation; the mortality while waiting was 3% after a median of 229.5 days. In contrast, only 3% of those entered at the highest risk UNOS 5 category survived without transplantation; 28% died while waiting, the deaths occurring at a median of 5.5 days. The UNOS categories in between showed the expected gradations, in which at each higher level fewer patients remained as candidates throughout the 1-yr duration of study while progressively more died at earlier and earlier times while waiting for an organ. In a separate study of posttransplantation survival during the same time period, the best postoperative results were in the lowest-risk UNOS 1 and 2 patients (88% combined), and the worst results were those in UNOS 5 (71%). However, a relative risk cross-analysis showed that a negative benefit of transplantation may have been the result in terms of 1-yr survival for the low-risk elective patients, but that a gain in life extension was achieved in the potentially lethal UNOS categories 3, 4 and 5 (greatest for UNOS 3). These findings and conclusions are discussed in terms of total care of patients with liver disease, and in the context of organ allocation policies of the United States and Europe

Trends in the knowledge, attitudes and practices of travel risk groups towards prevention of malaria: Results from the Dutch Schiphol airport survey 2002 to 2009

Background: Previous studies investigating the travellers knowledge, attitudes and practices (KAP) profile indicated an important educational need among those travelling to risk destinations. Initiatives to improve such education should target all groups of travellers, including business travellers, those visiting friends and relatives (VFRs), and elderly travellers. Methods: In the years 2002 to 2009, a questionnaire-based survey was conducted at the Dutch Schiphol Airport with the aim to study trends in KAP of travel risk groups towards prevention of malaria. The risk groups last-minute travellers, solo-travellers, business travellers, VFRs and elderly travellers were specifically studied. Results: A total of 3,045 respondents were included in the survey. Travellers to destinations with a high risk for malaria had significantly more accurate risk perceptions (knowledge) than travellers to low-risk destinations. The relative risk for malaria in travellers to high-risk destinations was probably mitigated by higher protection rates against malaria as compared with travellers to low risk destinations. There were no significant differences in intended risk-taking behaviour. Trend analyses showed a significant change over time in attitude towards more risk-avoiding behaviour and towards higher protection rates against malaria in travellers to high-risk destinations. The KAP profile of last-minute travellers substantially increased their relative risk for malaria, which contrasts to the slight increase in relative risk of solo travellers, business travellers and VFRs for malaria. Conclusions: The results of this sequential cohort survey in Dutch travellers suggest an annual 1.8% increase in protection rates against malaria coinciding with an annual 2.5% decrease in intended risk-seeking behaviour. This improvement may reflect the continuous efforts of travel health advice providers to create awareness and to propagate safe and healthy travel. The KAP profile of last-minute travellers, in particular, substantially increased their relative risk for malaria, underlining the continuous need for personal protective measures and malaria chemoprophylaxis for this risk group

Orthotopic liver transplantation for acute and subacute hepatic failure in adults

The role of liver transplantation in 29 patients with fulminant and subacute hepatic failure due to a variety of different causes was examined by comparing the outcome and a variety of “hospitalization” variables. Transplanted patients (n = 13) were more likely to survive (p < 0.05), were younger (p < 0.05) and spent more time in the hospital (p < 0.025) than did those who were not transplanted (n = 16). Despite spending a much longer time in the hospital, transplanted patients spent less time in the intensive care unit (p < 0.05) in coma (p < 0.01) and on a respirator (p < 0.01) than did those not transplanted. Most importantly, the survival rate for transplanted patients was significantly improved (p < 0.05) as compared to those not transplanted. We conclude that liver transplantation can be applied successfully to the difficult clinical problem of fulminant and subacute hepatic failure.

LONG TERM RESULTS OF HEPATIC TRANSPLANTATION DURING THE CYCLOSPORINE ERA: THE PITTSBURGH EXPERIENCE.

We have reviewed the long term results of the first 500 liver transplant recipients performed by our group during the cyclosporine era. Three hundred and forty-nine recipients lived (69.8%) more than 1 year and the projected 5 year actuarial survival for this sub-group of patients is 88%. The two most common causes of graft dysfunction after the first year were recurrence of the original disease, usually malignancy, and chronic rejection. Most episodes of rejection can be controlled with medical treatment; however, 16 patients of 34 patients who experienced rejection episodes after the first year required retransplantation. Eleven of these 16 are currently alive and free of jaundice. Another common cause of late graft dysfunction is biliary strictures. The recognized side effects of cyclosporine such as nephrotoxicity and lymphoproliferative disease have been lesser problems as a result of the judicious use of the drug. The quality of life of long term survivors is excellent

Resolution of the clinical features of tyrosinemia following orthotopic liver transplantation for hepatoma

The clinical history before transplantation and subsequent clinical and biochemical course of 3 children and one adult with hereditary tyrosinemia treated by orthotopic hepatic transplantation is described. All four patients are now free of their previous dietary restrictions and appear to be cured of both their metabolic disease and their hepatic neoplasm. © 1986 Elsevier Science Publishers B.V.

Effect of race upon organ donation and recipient survival in liver transplantation

The effect of the race of the donor on organ donation and on the outcome of clinical liver transplantation has not been addressed previously. The aims of this study were to determine: (1) the number of organs donated by each of the major racial groups of the United States, (2) the outcome of transplantation of these organs across racial groups, and (3) the pattern of liver disease that required transplantation in each of these racial groups. A significantly higher proportion of organs were donated by white non-Hispanic Americans than either black or Hispanic Americans. There was no significant difference in survival when an organ was transplanted between black and white Americans and vice versa. Postnecrotic cirrhosis from a variety of causes was the most common indicator affecting black and white recipients, while primary biliary cirrhosis and primary sclerosing cholangitis were uncommon in the black population. While the number of organs donated by blacks was low, it was, however, proportional to the number of black recipients in this study. Reasons for the low rate of donation by the black and white Hispanic population are discussed. It is concluded that race is not a criteria to be used in selection of donors for liver transplantation. Educational programs addressing issues of organ donation and transplantation directed towards the black and Hispanic populations are recommended. © 1990 Plenum Publishing Corporation

Intestinal transplantation in children under FK 506 immunosuppression

Intestinal transplantation, solitary (n = 3) or in combination with the liver (n = 7), was performed in 10 pediatric patients with intestinal failure. The liver was only replaced if there was liver failure and portal hypertension. Immunosuppression was based on FK 506. Two patients died, one of graft-versus-host disease and one of lymphoproliferative disease. One patient was still in the intensive care unit 1 month posttransplantation due to perioperative complications. The function of the intestinal grafts in the remaining patients is normal. All nutrition and medications including immunosuppression are being administered enterally. This series indicates that small bowel transplantation, alone or in combination with the liver, is feasible in pediatric patients. © 1993
