ABSTRACT

The topic of this monograph is liver cancer associated with chronic HCV infection. We start with some background information on chronic HCV infection and its long-term sequelae, one of which is liver cancer. The rest of the article is concerned with liver cancer or hepatocellular carcinoma (HCC). Epidemiology, risk factors, treatment and outcomes are discussed. We focus on those aspects that are of specific interest in people with haemophilia: studies performed in haemophilia populations, the use of invasive diagnostic and therapeutic tools and the outcome of liver transplantation. Throughout the paper, recommendations are given on surveillance for and diagnosis of HCC and on the practical aspects of invasive procedures. These recommendations are based on professional guidelines, other published evidence and the authors' experience. In general, diagnostic and therapeutic options are the same in persons with and without haemophilia.

ABSTRACT

Survival outcomes after liver transplantation in adult patients have gradually improved with a five-year survival of about 70% and a ten-year survival of about 60%. The present review focuses on relevant patient-reported outcomes such as self-perceived side effects of immunosuppressive drugs, medication nonadherence and long-term health-related quality of life after liver transplantation. These entities are interrelated but have often been studied separately. Self-perceived symptom experience in liver transplant recipients has not been studied extensively. Symptoms that cause distress differ between men and women, e.g. symptoms related to cosmetic side effects of drugs. Medication nonadherence seems to be infrequent, but if present may have serious consequences. Important risk factors were found to be the costs of drugs, age <40 years, psychiatric disorders, side effects of drugs, beliefs that drugs were harmful, and large influence of the liver transplant on the patient's life. Health-related quality of life is satisfactory, but below the level of the general population. Results, however, must be interpreted with caution as quality-of-life improvements may have been overstated due to variables such as selection bias (e.g. exclusion of severely ill and deceased patients), too many short-term studies, and suboptimal methodology. Presently we lack data on the influence of recurrence of disease, 'de novo' diseases and gender differences on health-related quality of life in liver transplanted patients.

ABSTRACT

Symptom experience (occurrence and perceived distress) associated with side effects of immunosuppressive medications in organ transplant patients may well be associated with poorer quality of life and medication non-compliance. The aims of this study were: first, to assess symptom experience in clinically stable adult patients during long-term follow-up after liver transplantation; and second, to study the relationship between symptom experience and medication non-compliance. This cross-sectional study included 123 liver transplant patients. Symptom experience was assessed using the "Modified Transplant Symptom Occurrence and Symptom Distress Scale" (29-item version) at the annual evaluation. According to the duration of follow-up, patients were divided into a short-term (1-4 yr) and a long-term (5-18 yr) cohort. Medication non-compliance was measured using electronic monitoring. Results showed that increased hair growth was the most frequent symptom in both sexes. Symptom distress was more serious in women than in men. The most distressing symptom in women was excessive and/or painful periods, while in men this was impotence. Clear differences were revealed at item level between symptom occurrence and symptom distress in relationship with the two time cohorts and between sexes. No relationship was found between symptom experience and prednisolone non-compliance.

ABSTRACT

Liver transplantation has been an accepted treatment for end-stage liver disease since the 1980s. Currently it is a highly successful treatment for this indication. The aim of this review is to give a general update on recent developments in the field of liver transplantation. In the last decades considerable progress has been made in the care of liver transplant candidates and recipients. At present the one- and five-year patient survival rates are approximately 85 and 75%. The indications for liver transplantation are shifting and the number of absolute contraindications is decreasing. In the coming years, an increase in the number of transplant candidates can be expected. An important problem is the shortage of donor organs, for which many solutions are being explored. A recently introduced method for recipient selection is the MELD score using simple laboratory measurements. Perioperative care at the present time is characterised by a high degree of standardisation and rapidly declining blood loss during transplantation. Long-term care includes awareness and management of recurrent disease. Important causes of morbidity and mortality such as de novo malignancies and cardiovascular disease should be adequately screened for and managed. With the increasing success of liver transplantation, physicians should aim at reaching a normal life expectancy and quality of life for transplant recipients.

ABSTRACT

BACKGROUND: Liver transplantation was started in our centre as early as 1979. We have studied the clinical outcome of patients surviving longer than 15 years, with special interest for the broad range of comorbidity and the self-perceived quality of life. METHODS: All patients who underwent a liver transplantation at an adult age, between March 1979 and February 1991, and who had survived at least 15 years were eligible for the study. Data were collected from the medical records. Health-related quality of life was assessed using the Six-Dimensional EuroQol test. RESULTS: The five-year survival of patients alive 15 years after transplantation was 78%. Thirty-seven patients are currently alive with a median follow-up of 18.8 years (range 15.0 to 26.8) after transplantation. Comorbidity consists predominantly of overweight (57%), osteoporosis (49%), de novo cancer (38%, mainly skin cancer), hypertension (38%), cardiovascular events (19%), diabetes mellitus (22%), cataract (24%), and renal clearance<50 ml/min (11%). The pattern of comorbidity seems to relate to the type of immunosuppression which consisted mainly of prednisolone and azathioprine. Quality of life was perceived as satisfactory (7 on a scale of 0 to 10). However, about half of the patients reported limitations in the domains mobility, usual activities and pain/discomfort. In addition a minority reported some anxiety or depression. CONCLUSION: The outcome of liver transplantation in this early cohort of patients is fairly good. Improvements may be achieved by adaptations in the immunosuppressive regimen.

ABSTRACT

BACKGROUND: Regulatory T-cells (Treg) are natural suppressors of autoimmunity. Previous studies indicate that immunosuppressive drugs, especially calcineurin-inhibitors, may interfere with Treg homeostasis. Inflammatory bowel disease (IBD) can relapse or develop de novo after liver transplantation. IBD is associated with a relative deficiency of Treg. The aim of this study was to determine the effect of long-term immunosuppression on the presence of Treg in the noninflamed colonic mucosa of liver transplant recipients. METHODS: Colonic biopsies of normal mucosa of 36 liver transplant recipients on different types of immunosuppression and 11 controls were studied. Treg marker Foxp3 and Treg products transforming growth factor-beta (TGF-beta) and interleukin-10 (IL-10) were studied by quantitative polymerase chain reaction (Q-PCR) and immunohistochemistry. TGF-beta-induced Smad-protein 3 and 7 were studied by Q-PCR. RESULTS: No significant differences between controls and patients were observed in IL-10, TGF-beta, and Smad expression. Mucosal Foxp3 mRNA levels and Foxp3+CD3+ cells were significantly reduced in transplant recipients using prednisone/azathioprine/tacrolimus compared with controls but no direct relationship between Foxp3 expression and 1 specific drug was detected. CONCLUSIONS: These results challenge the hypothesis that calcineurin-induced reduction of Treg or TGF-beta expression predisposes nontransplanted tissue to inflammation, but indicate that combined immunosuppression hampers Treg development in the intestine.

ABSTRACT

UNLABELLED: OBJECTIVE. To describe the experience with combined liver and kidney transplantation at the University Medical Centre Groningen, The Netherlands. DESIGN. Retrospective. METHOD: Data were analysed from all patients who underwent combined liver and kidney transplantation in the University Medical Centre Groningen, in the period November 1994-December 2005. RESULTS: During the study period 582 orthotopic liver transplantations and 1026 isolated kidney transplantations were performed. 16 patients underwent combined liver and kidney transplantation: 4 were children (aged 17 months-16 years) and 12 were adults (aged 19-59 years). For all patients, both organs were obtained from the same post-mortem donor. Indications for combined liver and kidney transplantation were primary hyperoxaluria type I (n=6), polycystic liver and kidney disease (n=3) and unrelated liver and kidney failure (n=7). The 1- and 5-year survival rate was 88% (14/16), which was not significantly different from the results after isolated liver transplantation. Two patients died 11 days and 74 months after combined transplantation, due to complications from unsuccessful retransplantation of the liver for hepatic artery thrombosis and secondary biliary cirrhosis, respectively. A third patient died 51 days after combined transplantation due to sepsis. CONCLUSION: Combined liver and kidney transplantation was a life-saving intervention in this selected group of patients with combined liver and kidney failure. Patient survival was comparable to that of patients undergoing isolated liver transplantation.

ABSTRACT

Inflammatory bowel disease (IBD) is associated with primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) and can recur or develop de novo after orthotopic liver transplantation (OLT). The aim of this study was to investigate the incidence and severity of IBD after liver transplantation and to perform a multivariate analysis for possible risk factors. In this retrospective study, 91 patients transplanted for PSC or AIH, without prior colectomy, were included. Sixty patients were transplanted for PSC, 31 for AIH. IBD activity before and after OLT and other possible risk factors were analysed in a multivariate model. Forty-nine patients (54%) had IBD before OLT. Forty patients (44%) had active IBD after transplantation: recurrence in 32 and de novo in 8. Cumulative risk for IBD after OLT was 15, 39 and 54% after 1, 5 and 10 years, respectively. In 59% of patients with IBD prior to OLT the disease was more active after transplantation. Risk factors for recurrent disease were: symptoms at time of OLT, short interval of IBD before OLT and use of tacrolimus. 5-aminosalicylates were protective. A cytomegalovirus positive donor/negative recipient combination increased the risk for de novo IBD.

ABSTRACT

BACKGROUND: Seemingly conflicting results have been reported on the prevalence and severity of inflammatory bowel disease after liver transplantation. Regimens with different combinations of drugs can be used for immunosuppression after transplantation. AIM: To study retrospectively the prevalence of inflammatory bowel disease after liver transplantation, and the possible relationship with maintenance immunosuppressive regimens. METHODS: All 78 patients with end-stage primary sclerosing cholangitis (48 patients) or autoimmune cirrhosis (30 patients), transplanted between 1979 and July 2001, and with a follow-up of at least 1 year, were eligible for this study. In addition to patient and transplant characteristics, data on inflammatory bowel disease and immunosuppression before and after transplantation were collected. The Kaplan-Meier method was used for survival analysis. Possible risk factors for inflammatory bowel disease after transplantation were analysed by Cox univariate and multivariate regression. RESULTS: The median follow-up after transplantation was 7.2 years (range, 1.1-22.3 years). Nine of 25 patients with pre-transplant inflammatory bowel disease experienced flare-ups after transplantation. Six of 53 patients without pre-transplant inflammatory bowel disease developed de novo inflammatory bowel disease after transplantation. The cumulative risks (standard errors in parentheses) for inflammatory bowel disease were 6% (3%), 12% (4%) and 20% (5%) at 1, 3 and 5 years after transplantation, respectively. The inflammatory bowel disease-free survival was significantly higher in patients not receiving tacrolimus vs. those receiving tacrolimus, in patients receiving azathioprine vs. those not receiving azathioprine and in patients taking the regimen prednisolone-azathioprine-ciclosporin A vs. those taking tacrolimus-prednisolone. Pre-transplant inflammatory bowel disease and the use of tacrolimus were found to be independent predictors for inflammatory bowel disease after transplantation. CONCLUSIONS: The prevalence of inflammatory bowel disease after liver transplantation is affected by the immunosuppression used. Azathioprine seems to have a protective effect and tacrolimus a promoting effect.

ABSTRACT

A 42-year-old woman developed jaundice due to acute hepatitis several weeks after ingestion of a herbal preparation containing greater celandine (Chelidonium majus) and curcuma root, which had been prescribed by an alternative therapist due to a skin complaint. After the medication had been withdrawn, clinical recovery was rapid and the hepatic functions returned to normal within 2 months. The hepatitis was ascribed to the known hepatotoxic effects of C. majus. In view of the increasing popularity of herbal remedies, greater awareness of side effects, such as hepatotoxicity, is needed. Quite a number of herbal preparations carry the risk of liver damage. The supposed clinical effectiveness of herbal remedies does not seem to always outweigh the potential risks. In the event of non-clarified liver function disturbances the ingestion of supposedly harmless, but potentially hepatotoxic, herbal products should be considered.

ABSTRACT

BACKGROUND/AIMS: It is unclear whether treatment of patients with Budd-Chiari syndrome (BCS) should be based on liver histology, as large histopathological studies have not been performed. We investigated the relationship between the histopathological findings and survival. METHODS: We studied the clinical features and findings on biopsy specimens in 45 patients with BCS who were admitted to four tertiary referral medical centers. Histological findings, i.e. congestion, necrosis, inflammation and fibrosis, were graded. Survival was assessed in relation to histological findings and clinical features at the time of diagnosis as well as in relation to subsequent treatment with or without portosystemic shunting. RESULTS: Centrilobular congestion, centrilobular necrosis, lobular inflammation and portal inflammation were not significantly related to survival. In addition, there was no association between either pericentral or periportal fibrosis and survival. Univariate analysis revealed that the prothrombin time and Child-Pugh score were significantly related to survival (P = 0.005 and Ptrend = 0.02, respectively). Multivariate analysis yielded the Child-Pugh score, serum alanine aminotransferase (ALT) and treatment with portosystemic shunting as independent prognostic indicators. CONCLUSIONS: We found no evidence for a relationship between early liver pathology and survival. Child-Pugh score, serum ALT and portosystemic shunting appeared to be prognostic indicators for patients with BCS.

ABSTRACT

BACKGROUND: Malignancy, hypercoagulability, and conditions leading to decreased portal flow have been reported to contribute to the aetiology of extrahepatic portal vein thrombosis (EPVT). Mortality of patients with EPVT may be associated with these concurrent medical conditions or with manifestations of portal hypertension, such as variceal haemorrhage. PATIENTS AND METHODS: To determine which variables have prognostic significance with respect to survival, we performed a retrospective study of 172 adult EPVT patients who were followed over the period 1984-1997 in eight university hospitals. RESULTS: Mean follow up was 3.9 years (range 0.1-13.1). Overall survival was 70% (95% confidence interval (CI) 62-76%) at one year, 61% (95% CI, 52-67%) at five years, and 54% (95% CI, 45-62%) at 10 years. The one, five, and 10 year survival rates in the absence of cancer, cirrhosis, and mesenteric vein thrombosis were 95% (95% CI 87-98%), 89% (95% CI 78-94%), and 81% (95% CI 67-89%), respectively (n=83). Variables at diagnosis associated with reduced survival according to multivariate analysis were advanced age, malignancy, cirrhosis, mesenteric vein thrombosis, absence of abdominal inflammation, and serum levels of aminotransferase and albumin. The presence of variceal haemorrhage and myeloproliferative disorders did not influence survival. Only four patients died due to variceal haemorrhage and one due to complications of a portosystemic shunt procedure. CONCLUSION: We conclude that mortality among patients with EPVT is related primarily to concurrent disorders leading to EPVT and not to complications of portal hypertension.

ABSTRACT

To evaluate the diagnostic value of combined contrast enhanced MRA (ce-MRA) and MRI compared to that of intra-arterial DSA (i.a.DSA) in liver transplantation, transjugular porto-systemic (TIPSS) and spleno-renal shunt candidates. 50 patients in the workup for liver transplantation underwent ce-MRA/MRI and i.a.DSA within a three days interval. Both examinations were assessed with respect to vessel anatomy and patency of the arterial, portal venous, porto-systemic collateral and systemic venous system. The results were compared with the intra-operative findings when available. Malignancy detection in ce-MRA/MRI and i.a.DSA were compared. There are no significant differences for the arterial part of the vascular supply to the liver that is important for transplantation. Although the differences for the portal system are not significant, the difference between the two techniques is of clinical importance because i.a.DSA failed to detect portal vein occlusion in 4 patients. Ce-MRA is significantly better for the detection of collaterals (p < 0.001) and the assessment of the inferior vena cava, the hepatic and the renal veins (p < 0.001). Although the detection of liver malignancy is poor in both techniques, ce-MRA/MRI is superior to i.a.DSA. This study shows that a one step diagnostic approach with a combination of ce-MRA and MRI is a valuable radiological tool with a superior diagnostic strength compared to i.a.DSA in the liver transplantation and shunt candidate. Therefore, ce-MRA/MRI should replace i.a.DSA in these patients groups.

ABSTRACT

BACKGROUND: A decrease in donor-specific T cell precursor frequencies as seen late, one or more years, after transplantation is assumed to reflect transplantation tolerance, a condition important for long term acceptance of the allograft. However, such late decreases also occur in recipients that developed chronic transplant dysfunction questioning its relevance in transplantation tolerance. We investigated whether early, i.e., the first 6 months, decreases in donor-specific T cell precursor frequencies reflect transplantation tolerance and predict graft outcome after liver and lung transplantation. METHODS: Donor and third party specific cytotoxic (CTLp) and helper T lymphocyte precursor (HTLp) frequencies were analyzed in pretransplant and 1 (or 2) and 6-month blood samples taken from liver and lung recipients and were correlated with graft outcome. RESULTS: In liver allograft recipients with good graft function (n=7), mean donor-specific CTLp frequencies decreased as early as 1 month after transplantation and remained low thereafter. In contrast, mean CTLp frequencies did not decrease in liver allograft recipients with chronic transplant dysfunction (n=6). In lung allograft recipients, donor-specific CTLp frequencies remained relatively high and frequencies were not different between recipients without (n=6) or with (n=6) chronic transplant dysfunction. Donor-specific HTLp frequencies did not change significantly after liver or lung transplantation and did not differ between recipients without or with chronic transplant dysfunction. CONCLUSIONS: An early decrease in donor-specific CTLp correlates with good graft outcome after liver transplantation. Such rapid decreases in alloreactivity do not occur after lung transplantation illustrating the unique capacity of liver allografts to induce transplantation tolerance.

ABSTRACT

BACKGROUND/AIMS: Development of de novo malignancies emerges as a serious long term complication after liver transplantation. METHODS: We reviewed the medical records of 174 adult one-year survivors for de novo malignancies. The observed cancer rates were compared with the expected cancer rates in the Dutch population. RESULTS: Twenty-one of the 174 patients developed 23 malignancies (12%). Skin and lip cancer accounted for 12 of the 23 malignancies (52%). Only one patient had a B-cell lymphoma. The cumulative risk for de novo malignancy was 6, 20, and 55% at 5, 10, and 15 years after transplantation, respectively. The overall relative risk (RR) as compared with the general population was 4.3 (95% confidence interval 2.4-7.1). Significantly increased RRs were observed for non-melanoma skin cancer (RR 70.0), non-skin solid cancer (RR 2.7), renal cell cancer (RR 30.0), and colon cancer (RR 12.5). Multivariate analysis showed that an age > 40 years and pretransplant use of immunosuppression were significant risk factors. CONCLUSIONS: An increased risk of cancer exists after liver transplantation, for both for skin/lip cancer, and other solid tumors. Older age and the use of immunosuppression are risk factors.
