Abstract
BACKGROUND Hypertension and hypercholesterolemia are recognized complications of liver transplantation, but whether they contribute to the development of cardiovascular disease is uncertain. We aimed first to determine the prevalence of risk factors for coronary heart disease (CHD) after liver transplantation and second to study the effect of liver transplantation on the predicted 10-year risk of developing CHD and the incidence of cardiovascular events in comparison with a matched local population. METHODS Data on blood pressure, serum lipids, weight, diabetes mellitus, smoking, and incidence of myocardial infarction (MI) and stroke were obtained retrospectively from the case notes of 181 consecutive adult liver transplant recipients (median follow-up 54 months). The Framingham coronary risk equations were used to calculate the 10-year probability of developing CHD. RESULTS The prevalences of hypertension and hypercholesterolemia after transplantation were 77% and 62%, respectively. The predicted 10-year risk of CHD increased from 6.9% before transplantation to 11.5% at 1 year after transplantation, whereas that of a matched local population was 7%. Compared with a matched nontransplant population, the incidence ratios for MI and stroke were 0.55 (95% confidence interval, 0.01-3.06 ) and 1.45 (95% confidence interval, 0.18-5.22), respectively. No patients died from MI or stroke. CONCLUSIONS Liver transplant recipients have a high prevalence of risk factors for cardiovascular disease, exceeding that of the general population, and have a higher predicted risk of developing CHD. Despite this, there were no deaths from CHD or stroke during the study period.

Abstract
Although several studies have investigated short-term effects of liver transplantation on cognitive function and health-related quality of life, there have been no studies looking at long-term effects. Patients who received a single liver transplant at St James's University Hospital (Leeds, UK) before October 1, 1991, were invited to participate in this cross-sectional study. Cognitive function was assessed using the Mini-Mental State Examination, the Rey Auditory Verbal Learning Test, trail-making tests, the Stroop test, and the Benton Visual Retention Test. Anxiety and depression were documented using the Hospital Anxiety and Depression Scale. Health-related quality of life was assessed using the EuroQol. Twenty-five healthy volunteers acted as controls. Thirty-six patients had undergone transplantation before October 1, 1991. Thirteen patients (36%) had died, 6 patients had received more than one transplant, 2 patients did not speak English, and 3 patients did not want to participate, leaving 12 patients included in the study. Patients scored significantly lower on measures of health-related quality of life than healthy controls, but there were no differences in levels of anxiety or depression. Patients scored significantly lower than controls across a wide range of cognitive functions, suggesting global cognitive impairment. We show that patients who survive for more than 10 years after liver transplantation have significant cognitive dysfunction and poor health-related quality of life. Whether these patients never return to normal after transplantation or whether they experience an increased rate of decline in cognitive function and health-related quality of life is uncertain and requires further study.

Abstract
BACKGROUND Organ transplantation is a standard procedure today. Due to immunosuppressive drugs and increasing survival after organ transplantation, patients with transplanted organs carry an increased risk of developing malignant tumours. Accordingly, more patients with malignant tumours after transplantation will be faced by general or oncology surgeons. We report the case of a 48-year-old patient with advanced rectal cancer 6.5 years after pancreas-kidney-transplantation for type I diabetes. METHOD The patient was treated with neo-adjuvant radio-chemotherapy, followed by low anterior rectal resection with total mesorectal excision. Consecutively, a solitary hepatic metastasis, a solitary pulmonary metastasis and a chest wall metastasis were resected over the course of 13 months. RESULT The patient eventually died of metastasized cancer 32 months after therapy had been initiated, his organ grafts functioning well until his death. CONCLUSION Our case report provides evidence that transplantation patients should receive standard oncology treatment, including neo-adjuvant treatment, so long as their general condition and organ graft functions allow us to do so, although a higher degree of morbidity might be encountered.

Abstract
Although the focus in treating lipid disorders is on reducing LDL-C levels, additional lipid-related independent risk factors, such as TG, HDL-C, and Lp(a) levels, should be used clinically to assess cardiovascular risk. Decisions to initiate drug therapy for LDL-C reduction may be influenced by levels of these other lipoprotein fractions. Data supporting intervention to modify these factors are less abundant than for LDL-C reduction, but in certain circumstances. drug therapy targeted at TGs or HDL-C may be appropriate. Patients who have nephrotic syndrome and end-stage renal disease are at particularly high risk for the development of CVD and should be treated aggressively for their lipid disorders. Finally, solid organ transplant recipients are almost always hyperlipidemic and appropriate therapy could reduce cardiovascular events.

Abstract
INTRODUCTION Calcineurin inhibitors (CIs) cause substantial long-term morbidity and mortality among orthotopic liver transplantation (OLT) patients. Our aim was to evaluate the effectiveness and safety of mycophenolate mofetil (MMF) among OLT patients with CI-related side effects. PATIENTS Thirty three adult patients, including 29 men and 4 women of mean age 57 years, underwent OLT between 1986 and 2000 under treatment with CIs (28 cyclosporine and five tacrolimus). Mean follow-up after OLT was 59 months. Adverse effects were renal dysfunction in 26, hypertension in 23, and neurotoxicity in two. MMF was added gradually while simultaneously reducing the dosage of CI. RESULTS After a mean 15-months follow-up of MMF treatment, CIs had been withdrawn in 28 patients (85%). The mean time from the initiation of MMF and CI withdrawal was 5 months. During the first year of follow-up chronic renal dysfunction improved in 16 of 26 patients (61.6%) accompanied by a decreased serum creatinine and urea and an increase in creatinine clearance. Among 13/23 (56.5%) hypertensive patients, there was a significant decrease in blood pressure or the number of antihypertensive drugs (P<.05). One patient with neurotoxicity improved. Twenty-two patients (66%) displayed adverse events: five rejections (15%) including four acute episodes, controlled by CI re-introduction, and one chronic reaction. The most frequent adverse effects were herpes simplex infection in 10 patients (30%), asthenia in nine (27%), diarrhea in five (15%) and thrombocytopenia in four (12%). Nevertheless, only six patients (19%) required MMF dose reduction, namely, three patients with GI intolerance, two with repeated VHS infections, and one with anemia. CONCLUSIONS MMF monotherapy improves renal function and blood pressure levels in more than 50% of patients with chronic renal impairment and hypertension after OLT. Many of the side effects of MMF were mild; it was safe accompanied by a low incidence of rejection reactions.

Abstract
Renal dysfunction is common after liver transplantation. However, there are only limited data on the predictors and natural history of renal dysfunction after liver transplantation. In this study, we determined independent predictors and the natural history of renal dysfunction in 172 consecutive liver transplant recipients. Survival and time to development of permanent renal dysfunction (renal dysfunction defined as a sustained decrease in estimated glomerular filtration rate (GFR) of > 30 mL/min/1.73 m(2) from baseline for at least 6 months, severe renal failure defined as absolute GFR <30 mL/min/1.73 m(2) for at least 6 months) were determined using the Kaplan-Meier method. Cox regression analysis was used to test the independent effect of a given set of variables on time to development of such an event. Nine percent of patients required immediate dialysis, 35% developed permanent renal dysfunction, and 7% developed severe renal failure. The rate of decline in renal dysfunction was maximal, 6.5 mL/min/1.73 m(2) /mo, at 1 month after liver transplantation. Pre-existing diabetes mellitus, major surgical infection, and waiting time on the transplant list were independent risk factors for immediate dialysis. Presence of serum creatinine > 1.2 mg/dL at any time before liver transplantation and a baseline GFR <70 mL/min/1.73 m(2) were independent predictors of permanent renal dysfunction. Diabetes mellitus, coronary artery disease, and primary graft nonfunction predicted the development of severe renal failure. GFR stabilized around 9 months, and presence of decreased GFR > 30mL/min/1.73 m(2) from baseline at 9 months predicted development of permanent renal dysfunction. An absolute GFR of <30mL/min/1.73 m(2) occurring as early as 3 months after liver transplantation predicted severe renal failure. Severe renal failure was associated with a significantly lower survival by Cox regression analysis. We have identified risk factors and the natural history of permanent renal dysfunction and severe liver failure in liver transplant recipients. These observations may be useful in the development of nonnephrotoxic immunosuppressive regimens for high-risk liver transplant recipients.

Abstract
PURPOSE OF REVIEW Post-liver transplant patients present a vast array of metabolic changes in the early and late phase which impact on their morbidity and mortality. The development of obesity and diabetes in these patients has been widely described in the literature with several hypotheses suggested: liver donor, nutritional and metabolic state, and immunosuppressive drugs. RECENT FINDINGS Most that is known about the development of these metabolic derangements has been attributed to the drugs used, especially the corticosteroids. When these have been used in higher doses for longer periods to treat rejection, the incidence of diabetes and obesity seems to be higher. However cyclosporine and to a lesser extent tacrolimus are also related to these alterations. SUMMARY As long-term survival improves in liver transplant patients, cardiovascular complications associated with dyslipidemia, obesity, and diabetes are emerging as risk factors for late morbidity and mortality. Therefore, it is important to assess the potential risk factors related to these complications, in order to prevent or decrease their incidence. From what has been seen, immunossupressive drugs seem to be the greatest risk factor for the development of metabolic derangements in post-transplantation patients. However other risk factors might also be involved, such as non-healthy eating habits and lack of exercise. The latter can be preventable if counseling policies are targeted at these patients in the pre-transplantation phase and continued after the operation.

Abstract
A retrospective study was performed on all orthotopic liver transplant (OLT) recipients (n = 167) from a major French transplant center from January 1998 to December 2000. The investigation sought to determine the prevalence, predictive factors, and outcome of post-liver transplant diabetes mellitus (PTDM). PTDM was defined at 6 months post-OLT as hyperglycemia requiring treatment with insulin or oral hypoglycemic agents. The incidence was assessed for patient features, cause of liver disease, and immunosuppressive regimen. PTDM occurred in 45 of 143 OLT (31%), including 27 patients with pre-OLT persistent DM, whereas 26 developed de novo PTDM. Eight patients were cured of their post-OLT DM. PTDM treatment consisted of mainly insulin (n = 43). Patients given tacrolimus (n = 40) had a greater incidence of PTDM. Pre-OLT DM (n = 27), alcoholic cirrhosis (n = 30), and male gender (n = 38) were independent predictors of PTDM. Recipient HLA, steroid dosage, hepatitis C virus (HCV), and cholestatic liver disease were not predictive of PTDM. The incidences of graft loss as well as other morbidities and death rates were similar between the two groups. In conclusion, PTDM, common occurrence associated with male gender, alcoholic cirrhosis, and pre-OLT DM, seems at midterm follow-up to have no pejorative evolution when compared to patients without this complication.

Abstract
Sirolimus, being nonnephrotoxic, is a viable alternative in patients who develop renal insufficiency caused by calcineurin inhibitors (CIs). The aim of this study is to determine whether there is improvement in renal function in liver transplant recipients after switching to sirolimus-based immunosuppression. In this retrospective review, patients who were more than 3 years posttransplantation were selected. Patients who had proteinuria (protein > 300 mg/24 hr), those administered any other nephrotoxic agents, and those with a creatinine clearance (CCr) less than 20 mL/min were excluded. Renal insufficiency was defined as mild (CCr > 70 mL/min), moderate (CCr, 40 to 70 mL/min), or severe (CCr, 20 to 40 mL/min). In the 16 patients studied; there was significant improvement in serum blood urea nitrogen (36 mg/dL; range, 19 to 53 mg/dL; to 25 mg/dL; range, 10 to 37 mg/dL; P =.002) and serum creatinine levels (median, 1.95 mg/dL; range, 1.3 to 2.8 mg/dL; to 1.5 mg/dL; range, 1.0 to 2.4 mg/dL; P =.001) 6 months after switching to sirolimus therapy. There also was a trend in improvement in CCr from 43 mL min (range, 24 to 68 mL/min) to 49 mL/min (range, 22 to 152 mL/min). Among 9 patients with moderate renal insufficiency, 2 patients improved to mild renal insufficiency, 4 patients remained unchanged, and 3 patients deteriorated to severe renal insufficiency. Among 7 patients with severe renal insufficiency, 1 patient improved to mild renal insufficiency, 4 patients improved to moderate renal insufficiency, and 2 patients remained unchanged. No patient developed cellular rejection or other graft-related complications. In liver transplant recipients with chronic renal insufficiency, conversion to sirolimus-based immunosuppression allows complete withdrawal of CIs, leading to some improvement in renal function.

Abstract
Advances in liver transplantation continue to evolve but are hampered by continued increasing shortages in donor organs. This has resulted in a high incidence of patients dying while on the United Network for Organ Sharing waiting list. Indeed, we continue to assess ways of expanding the donor pool by using marginal donors, living donor liver transplantation, split liver transplantation, domino transplantation, and hepatic support systems to prolong survival long enough for the patient to undergo liver transplantation. Changes in the liver allocation policy to reduce the number of people dying while waiting for an organ are discussed. Implementation of the model for end-stage liver disease allocation system should help alleviate the problem of increasing deaths of patients while on the waiting list. Recurrent disease, particularly recurrent hepatitis C, continues to be a major problem, and effective therapy is needed to prevent both progression of hepatitis C and recurrence in the graft and avoid retransplantation. The use of pegylated interferon in combination with ribavirin holds promise for improving the success in overcoming recurrent hepatitis C. Finally, advances in immunosuppression have reduced the incidence of acute cellular rejection and chronic rejection. However, these therapies have been fraught with metabolic complications that are now affecting quality of life and long-term survival. Tailoring immunosuppressive regimens to the individual patient is discussed.

Abstract
Transplantation between monozygotic twins has been successfully performed using the kidney, small intestine, and pancreas. Identical HLA matching has enabled these individuals to be transplanted without the need for immunosuppressive medication. Liver transplantation without immunosuppression would lessen the risk of recurrent viral hepatitis and eliminate much of the morbidity associated with long-term use of immunosuppressive medication. Living-donor liver transplantation (LDLT) has been performed with increasing success in recent years without an opportunity arising to use a monozygotic twin as a donor. We report 2 cases of LDLT between identical twins wherein perfect haploidentity has allowed these recipients to be transplanted without the need for immunosuppression. Although HLA matched genotypically, there may be differences in anatomy between donor and recipient. Mild liver chemistry test abnormalities may occur after transplant despite the absence of immunosuppression.

Abstract
Chronic nephrotoxicity is one of the most serious side-effects of calcineurin inhibitor treatment and a factor in mortality and morbidity after liver transplantation. In our transplant centre, among patients who underwent a liver transplantation between January 1989 and December 2000, 14 liver graft recipients (6.86%) developed de novo severe renal dysfunction as defined by a serum creatinine concentration above 200 micromol/L. Renal biopsy was performed in nine cases and evidenced histological lesions compatible with chronic nephrotoxicity related to calcineurin inhibitor treatment. For nine patients, we report the results of a prospective non-randomized study consisting of cyclosporine or tacrolimus withdrawal associated with administration of mycophenolate mofetil or azathioprine. Despite this therapeutic modification, we did not observe a significant renal function improvement but on the other hand, there was no graft rejection.

Abstract
BACKGROUND The purpose of this study was to examine the long-term survival and causes of death in patients who survive the first year after liver transplantation. METHODS The focus of the analysis was 433 patients who survived for at least 1 year after liver transplantation between November 1, 1984, and December 31, 2001. A total of 586 liver transplants were performed in 542 patients during this time period. The overall 1-, 5-, and 10-year survivals and the 5- and 10-year survivals for those patients who lived for a year were analyzed on the basis of Kaplan-Meier survival estimates. Factors examined included diagnosis, sex, age, and retransplantation. The causes of death were also analyzed. RESULTS The overall 1-, 5-, and 10-year survivals were 85%, 73%, and 55%, respectively. The 5- and 10-year survivals for those patients who lived for a year were 86% and 65%, respectively. Fifty-one percent of the causes of late death were graft-related, 71% from recurrent primary disease. Cardiovascular events and de novo malignancies were responsible for 65% of the nongraft-related deaths. CONCLUSIONS The long-term survival in patients who survive for the first year after liver transplantation is excellent. Recurrent primary disease is responsible for the majority of graft-related deaths. Cardiovascular events and de novo malignancy cause most of the nongraft-related deaths.

Abstract
BACKGROUND Atopic eczema is a chronic inflammatory skin disease, which in most children can be adequately controlled using topical therapy. However, in a small number of children it is necessary to use systemic treatments to gain an acceptable level of disease control. OBJECTIVES To evaluate azathioprine as a treatment for severe atopic eczema in children, and the value of pretreatment thiopurine methyltransferase (TPMT) levels in the identification of patients at high risk of myelosuppression. METHODS Between January 1997 and May 2000, 91 children had erythrocyte TPMT assays with the intention of treating their atopic eczema with azathioprine. This study is based on retrospective examination of data taken from the hospital notes of these children, who had attended Great Ormond Street Hospital for Children and St John's Institute of Dermatology, London. RESULTS The distribution of TPMT values corresponded closely to that previously described in adults. Forty-eight children were commenced on treatment with azathioprine. Twenty-eight had an excellent response to treatment, 13 had a good response and seven had a poor response. No patient developed neutropenia. CONCLUSIONS Azathioprine may prove a very valuable treatment for severe atopic eczema in children. We consider its short-term adverse effect profile in children with normal TPMT activity to have been entirely acceptable with our treatment protocol. As result, we now feel confident to initiate therapy at dose levels of 2.5-3.5 mg kg(-1) in those with a normal TPMT level, and to reduce the frequency with which we undertake tests of bone marrow and liver function.

Abstract
Pulmonary embolism has been considered uncommon in chronic dialysis patients, but has not been adequately studied in a large population. In the US Renal Data System (USRDS), 76,718 patients presenting with end-stage renal disease (ESRD) between January 1, 1996, and December 31, 1996, were analyzed in an historical cohort study. The outcome was hospitalizations with a primary discharge diagnosis of pulmonary embolism (International Classification of Diseases, Ninth Revision code 415.1x) occurring within 1 year of the first ESRD treatment and excluding those occurring after renal transplantation. For dialysis patients, hospitalization rates for pulmonary embolism were obtained from the hospitalization section of the 1999 USRDS. For the general population, hospitalization rates for pulmonary embolism were obtained from the National Hospital Discharge Survey for 1996. Comorbidities from the Medical Evidence Form (Centers for Medicare and Medicaid Services, previously known as the Health Care Financing Administration; form 2728) were used to generate approximated stratified models of adjusted incidence ratios for pulmonary embolism (comorbidities could not be stratified for the general population). In 1996, the overall incidence rate of pulmonary embolism was 149.90/100,000 dialysis patients compared with 24.62/100,000 persons in the US population, with an age-adjusted incidence ratio of 2.34 in dialysis patients. Younger dialysis patients had the greatest relative risk for pulmonary embolism. The age-adjusted incidence ratio of pulmonary embolism after excluding dialysis patients with known risk factors for pulmonary embolism was 2.11. Ninety-five percent confidence intervals for all age categories in both models were statistically significant. Chronic dialysis patients have high risk for pulmonary embolism, independent of comorbidity.

Abstract
Organ transplant recipients are considered to be at greater risk for developing malignancy because of the prolonged immunosuppression associated with organ grafting. The purpose of this study is to determine risk factors, clinical characteristics, and outcomes of de novo nonlymphoid malignancies after liver transplantation from a large single-center series. All patients undergoing liver transplantation at the King's College Hospital (London, UK) between January 1988 and December 1999 were analyzed retrospectively for the development of de novo malignancy in the posttransplantation period. Records were evaluated for age at diagnosis of malignancy, cause of liver disease, interval from transplantation to diagnosis of malignancy, predisposing factors for the development of cancer, immunosuppression regimen, treatment of malignancy, rejection episodes, and patient survival. Of 1,140 patients undergoing 1,271 liver transplantations, 30 patients (2.6%) developed de novo nonlymphoid malignancy after transplantation. Skin cancers were the most common (n = 13), followed by oropharyngeal carcinoma (n = 2), bladder carcinoma (n = 2), acute leukemia (n = 2), breast carcinoma (n = 2), and various other malignancies (n = 9). The mean time of presentation of the malignancy after transplantation was 45.1 +/- 32 months (range, 6 to 133 months), and mean age at diagnosis of malignancy was 55 years (range, 34 to 71 years). The incidence of de novo malignancy was significantly greater in patients who underwent transplantation for alcoholic liver disease compared with other groups (P <.001). Although the incidence of de novo nonlymphoid malignancy after liver transplantation is low, patients who underwent transplantation for alcoholic cirrhosis appear to have an increased risk for developing posttransplantation malignancy.

Abstract
PURPOSE African Americans have increased risk for congestive heart failure (CHF) compared to Caucasians in the general population, but the risk of CHF in African American renal transplant recipients has not been studied in a national renal transplant population. METHODS Therefore, 33,479 renal transplant recipients in the United States Renal Data System (USRDS) from 1 July, 1994 to 30 June, 1997 were analyzed in an historical cohort study of the incidence, associated factors, and mortality of hospitalizations with a primary discharge diagnosis of CHF [International Classification of Diseases-9 (ICD9) Code 428.x]. RESULTS African American renal transplant recipients had increased age-adjusted risk of hospitalizations for congestive heart failure compared to African Americans in the general population [rate ratio 4.60, 95% confidence interval (CI) 4.59-4.62]. In logistic regression analysis, African American recipients had increased risk of congestive heart failure after renal transplantation, independent of other factors. Among other significant factors associated with congestive heart failure, the strongest were graft loss and allograft rejection. No maintenance immunosuppressive medications were associated with CHF. In Cox regression analysis patients hospitalized for CHF had increased all-cause mortality compared with all other recipients (hazard ratio 3.69, 95% CI, 2.23-6.10), but African American recipients with CHF were not at significantly increased risk of mortality compared to Caucasian recipients with CHF. CONCLUSIONS African Americans recipients were at high risk for CHF after transplant independent of other factors. The reasons for this increased risk should be the subject of further study. All potential transplant recipients should receive particular attention for the diagnosis and prevention of CHF in the transplant evaluation process, which includes preservation of allograft function.

Abstract
The aim of this study is to investigate the effects of anxiety, depression, and coping on quality of life in patients after liver transplantation. Patients were asked to fill out a postal survey. Two hundred thirty-six of 375 patients (63%) who entered the study returned the questionnaires, and 186 of these patients could be included in the assessment. Anxiety and depression were surveyed using the Hospital Anxiety and Depression Scale; health-related quality of life, using the 36-Item Short-Form Health Survey; and coping strategies, using the Freiburg Questionnaire on Coping With Illness. In terms of physical and mental dimensions of health-related quality of life, psychosocial factors are far more relevant in liver transplant recipients than purely somatic factors, such as the number of posttransplantation complications or length of hospital stay. Through multiple regression analysis, we were able to account for 51% of the variance in the physical dimension of health-related quality of life and 58% of the variance in the mental dimension. Physical factors of depression, age, and employment and mental factors of anxiety and depression were significant for predicting health-related quality of life after liver transplantation. Depressive coping, anxiety, and depression, as well as aspects of the social environment, contribute considerably to determine well-being and health-related quality of life of patients after liver transplantation.

Abstract
Malignancy following renal transplantation is an important medical problem during the long-term follow-up. The overall incidence of malignancy at this time is 3 to 5 times higher than in the general population. The most common malignancies are lymphoproliferative disorders (early after transplantation) and skin carcinomas (late after transplantation). The type of malignancy is different in various countries and dependent on genetic and environmental factors. Another important confounder for risk of malignancy after renal transplantation is the type of immunosuppression. Previous use of cytotoxic drugs (eg, cyclophosphamide) or a history of analgesic abuse are additional risk factors. Malignancy may even be transplanted by the graft. Previous cancer treatment in a uremic patient on the transplant waiting list is of great importance in relation to waiting time and postmalignancy screening. Finally, every dialysis patient on the waiting list should undergo a regular screening program before and after renal transplantation to detect a potentially malignant tumor in an early stage. In addition to specific oncological treatment, managing a malignancy after renal transplantation should include modification of immunosuppression.

Abstract
Hypercholesterolemia is a common complication of liver transplantation and is a risk factor for cardiovascular disease after renal and heart transplant. The effect of hyperlipidemia after liver transplantation is less certain, but a less favorable outcome is to be expected. 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors or statins have proven efficacy in reducing serum cholesterol and mortality from cardiovascular disease in the general population. Early evidence shows that statins are safe and effective in treating hypercholesterolemia after liver transplantation. Studies in cardiovascular disease have shown that statins exhibit beneficial properties independent of lipid-lowering. These include anti-inflammatory effects and improvement in endothelial function. Recently, statins were shown to repress induction of major histocompatibility complex class II complexes by interferon-gamma, which in turn suppresses activation of T lymphocytes. Such effects may assume significance when using statins after solid-organ transplants. Pravastatin has been shown to reduce acute rejection after cardiac and renal transplantation and to also reduce natural killer cell cytotoxicity in these populations. It remains to be seen whether statins will demonstrate similar benefits after liver transplantation.

Abstract
Bone mineral density (BMD) and biochemical markers of bone metabolism were analyzed in 67 adults with ALL (n = 27), AML (n = 14), MDS (n = 6) and CML (n = 20) before and after allogeneic stem cell transplantation (SCT). Median age was 36 years (17-56). Twenty-six out of 53 patients (49%) had osteopenia and osteoporosis before SCT, 21/26 had acute leukemias and 5/26 had chronic myeloid leukemia (CML). T-score before SCTwas -1.23 in patients with acute leukemias and 0.62 in CML patients (P = 0.001). After SCT, a significant loss of BMD was observed in all patients. After 6 months, 24 of 36 evaluable patients (67%) had pathologic BMD, 11 of them (30%) had developed osteoporosis. After 12 months, 20 of 32 evaluable patients (62%) had BMD values below normal and nine of them (28%) had osteoporosis. Increased pyridinium excretion was observed in 12/20 patients (60%) with acute leukemias, but only in 3/13 (23%) with CML (P = 0.014). A prolonged vitamin D deficiency for more than 6 months developed early after SCT in all patients. Patients with acute leukemias frequently have osteopenia and osteoporosis before SCT. After SCT, a further loss of BMD occurs independent from the underlying disease. Standard prophylactic measures are not sufficient to prevent loss of bone mass. Studies on prophylactic interventions are needed to prevent severe osteoporosis in long-term survivors of SCT.

Abstract
1. Recurrent and de novo malignancies are the second leading causes of late death in liver transplant recipients, following age-related cardiovascular complications. 2. The increased incidence of de novo malignancies in liver transplant recipients compared with the general population reflects their demographic makeup, known preexistent risk factors for cancer, greater rate of chronic viral infection, and actions of exogenous immunosuppression. 3. The greatest incidence of de novo malignancies is seen in cancers associated with chronic viral infections, such as Epstein-Barr virus-associated posttransplant lymphoproliferative disease, and skin cancers, including squamous cell carcinoma and Kaposi's sarcoma. 4. Although a greater incidence of such malignancies as oropharyngeal malignancy and colorectal cancer was noted, there did not appear to be an increased risk for liver transplant recipients matched for age, sex, and length of follow-up using modified life-table technique and Surveillance Epidemiology End Result data with a similar at-risk group. However, they may present with more advanced stages of disease. 5. An increased incidence of de novo cancers in chronically immunocompromised liver transplant recipients demands careful long-term screening protocols to help facilitate diagnosis at an earlier stage of disease.

Abstract
1. As long-term survival improves after liver transplantation, cardiovascular complications are emerging as a major cause of late morbidity and mortality. It seems reasonable to correct the potentially reversible cardiovascular risk factors of diabetes, hyperlipidemia, and obesity, in addition to hypertension. 2. The results of liver transplantation in diabetics are acceptable in terms of morbidity, mortality, and prevalence of posttransplant diabetes, but the poor outcomes described in some series suggest that more extensive testing for macro- and microvascular disease may become necessary. 3. The management of diabetes in liver transplant recipients is not substantially different from its management in non-transplant patients, except that steroid reduction or withdrawal and minimizing doses of calcineurin inhibitors are beneficial. 4. Hyperlipidemia occurs in all solid-organ transplantation, with prevalence rates the lowest for liver transplant recipients. Following liver transplantation, between 15% and 40% of recipients on average have increased plasma cholesterol levels and about 40% have hypertriglyceridemia. Dietary changes, weight reduction, exercise and statins are the mainstays of therapy. 5. Retrospective studies suggest that long-term survival of obese recipients after liver transplantation does not differ from nonobese recipients. Posttransplant weight gain occurs in most recipients, and approximately two thirds become overweight. The management of posttransplant obesity is similar to that in non-transplant settings.

Abstract
1. Forty percent of transplant centers expect the primary care physician to be the primary physician; 40% have both a primary care physician and a hepatologist manage the patient. 2. Transplant centers expect primary care physicians to provide general preventive medicine, physical examinations, vaccinations, and, rarely, management of hypertension, renal dysfunction, and diabetes. 3. A high percentage of primary care physicians feel comfortable caring and managing the overall health care of a long-term liver transplant patient. 4. Primary care physicians feel at most ease managing preventive care, annual physical examinations, hypertension, diabetes mellitus, hyperlipidemia, bone disease, and vaccinations. 5. Primary care physicians should be aware of the common medical conditions of the liver transplant patient of hypertension, diabetes, obesity, hyperlipidemia, and recurrent disease. 6. Common medical conditions for both the transplant centers and primary care physicians are hypertension, dyslipidemia, diabetes mellitus, malignancy, bone disease, pregnancy, vaccination, infectious prophylaxis, and headaches.

Abstract
PURPOSE To investigate the incidence, risk factors, and associated mortality of fractures in renal transplant recipients. METHODS Retrospective registry study of 33,479 patients in the United States Renal Data System (USRDS) who received kidney transplants between 1 July 1994 and 30 June 1997. Associations with hospitalizations for a primary discharge diagnosis of fractures (all causes) were assessed. RESULTS Renal transplant recipients had an adjusted incidence ratio for fractures of 4.59 (95% confidence interval 3.29 to 6.31). In multivariate analysis, recipients with prevalent fractures, as well as recipients who were Caucasian, women, in the lower quartiles of recipient weight (<95.9 kg), had end stage renal disease caused by diabetes, and had prolonged pretransplant dialysis were at increased risk for hospitalization because of fractures after transplantation. Recipients hospitalized for hip fractures had decreased all-cause survival (hazard ratio for mortality 1.60, 95% CI 1.13 to 2.26) in Cox Regression analysis. CONCLUSIONS In the early post-transplant course (<3 years), renal transplant recipients had a greater incidence of fractures than the general population, which were associated with decreased patient survival. Preventive efforts should focus on recipients with the risk factors identified in this analysis, most of which can be easily obtained through history and physical examination.

Abstract
Non-melanoma skin cancer (NMSC) is an important cause of morbidity and long-term mortality in organ transplant recipients receiving immunosuppressive drugs such as azathioprine and cyclosporin, often combined with adrenocortical steroids (glucocorticoids). At lower doses, glucocorticoids alone are prescribed for other conditions including musculoskeletal, connective tissue and respiratory disorders. Presently, it is unknown whether patients taking glucocorticoids are at an increased risk of skin malignancies. In a population-based case-control study in New Hampshire, USA, we compared use of glucocorticoids in 592 basal cell carcinoma (BCC) and 281 squamous cell carcinoma (SCC) cases and in 532 age and gender matched controls; neither cases nor controls had a history of organ transplantation. Participants underwent a structured personal interview regarding history of medication use and skin cancer risk factors. We used unconditional logistic regression analysis to compute odds ratios associated with glucocorticoid use for 1 month or longer while controlling for potential confounding factors. Risk of SCC was increased among users of oral glucocorticoids (adjusted odds ratio = 2.31; 95% CI = 1.27, 4.18), and risk of BCC was elevated modestly (adjusted odds ratio = 1.49; 95% CI = 0.90, 2.47). In contrast, risk of both SCC and BCC were unrelated to use of inhaled steroids. Our data suggest that use of oral glucocorticoids may increase risk of NMSC, and SCC in particular, among patients other than organ transplant recipients. We hypothesize that immunosuppression induced by oral glucocorticoids may allow these cancers to emerge from immunosurveillance.

Abstract
Severe aplastic anemia (SAA) is well described in children following liver transplantation for fulminant hepatic failure (FHF) secondary to non-A, non-B, non-C hepatitis, and is associated with a high mortality rate. Successful immunosuppressive treatment of SAA following liver transplantation has been reported, but death from infectious complications is not uncommon. We report the 8-year follow-up of a 3.5-year-old boy who underwent successful HLA-identical sibling donor bone marrow transplant for SAA 7 months following orthotopic liver transplant for non-A, non-B, non-C hepatitis. His post-bone marrow transplantation course was uneventful with no evidence of liver toxicity. Eight months following BMT he developed renal cell carcinoma metastatic to lymph nodes which was treated surgically. Six years following BMT he developed a mucoepidermoid carcinoma of the parotid gland also treated surgically. Despite these malignancies, he is currently well 8 years following liver and bone marrow transplantation, without signs of GVHD, growth failure or liver graft rejection. This is the first report of long-term follow-up of bone marrow transplantation for SAA following liver transplantation. The occurrence of two subsequent malignancies in this child underscores the need for close follow-up of future similar cases.

Abstract
The recent focus on islet transplantation as primary therapy for type 1 diabetes has heightened interest in the reversal of type 1 diabetes in preclinical models using minimal immunosuppression. Here, we demonstrated in a preclinical rhesus model a consistent reversal of all measured glycemic patterns of streptozotocin-induced type 1 diabetes. The model used single-donor islet transplantation with induction of operational tolerance. The term "operational tolerance" is used to indicate durable survival of single-donor major histocompatibility complex (MHC)-mismatched islet allografts without maintenance immunosuppressive therapy and without rejection or loss of functional islet mass or insulin secretory reserve. In this operational tolerance model, all immunosuppression was discontinued after day 14 posttransplant, and recipients recovered with excellent health. The operational tolerance induction protocol combined peritransplant anti-CD3 immunotoxin to deplete T-cells and 15-deoxyspergualin to arrest proinflammatory cytokine production and maturation of dendritic cells. T-cell deficiency was specific but temporary, in that T-cell-dependent responses in long-term survivors recovered to normal, and there was no evidence of increased susceptibility to infection. Anti-donor mixed lymphocyte reaction responses were positive in the long-term survivors, but all showed clear evidence of systemic T-helper 2 deviation, suggesting that an immunoregulatory rather than a deletional process underlies this operational tolerance model. This study provides the first evidence that operational tolerance can protect MHC nonhuman primate islets from rejection as well as loss of functional islet mass. Such an approach has potential to optimize individual recipient recovery from diabetes as well as permitting more widespread islet transplantation with the limited supply of donor islets.

Abstract
Hypertension and hyperlipidemia are more prevalent after liver transplantation with cyclosporine as the primary immunosuppressive agent compared with tacrolimus. To determine whether blood pressure, serum lipid level, or weight improves when patients switch immunosuppression therapy, we retrospectively studied 26 liver transplant recipients with stable graft function who had been converted from cyclosporine to tacrolimus therapy with a median follow-up of 8 months. One of the 26 patients developed pruritus necessitating withdrawal of tacrolimus. The results therefore concern the remaining 25 patients. With the exception of a small decrease in bilirubin level (P <.05), there was no difference in graft or renal function after conversion. Mean systolic blood pressure decreased from 158 +/- 25 to 148 +/- 22 mm Hg over a mean of 8 +/- 3 months after conversion to tacrolimus (P =.015), whereas mean serum cholesterol level decreased from 5.3 +/- 0.9 to 4.9 +/- 0.9 mmol/L (P =.01). Sixty-eight percent of the patients lost weight, from a mean of 79.4 +/- 22.6 to 76.1 +/- 20.1 kg, in the 11 months after switching to tacrolimus therapy (P =.024). Serum triglyceride and blood glucose levels did not change, and no patient developed diabetes mellitus after conversion. These results indicate that switching from cyclosporine to tacrolimus can reduce blood pressure, serum cholesterol level, and weight after liver transplantation.

Abstract
Since its approval as an immunosuppressive agent in renal transplantation, sirolimus (RAPA) recently has been used in the primary immunosuppression regimen at several liver transplant centers. One of the major side effects of RAPA is hypercholesterolemia, which is reported in up to 44% of patients. We describe our experience in 57 primary liver transplant recipients treated with RAPA and either cyclosporine A (CSA) or tacrolimus (TAC). We report the incidence and severity of hypercholesterolemia using a prednisone-free immunosuppressive regimen. Between January 2000 and September 2000, a total of 57 patients underwent transplantation at the University of Colorado Health Sciences Center (Denver, CO) with RAPA and either CSA or TAC. The initial 10 patients who underwent transplantation under this protocol were not administered corticosteroids, and the subsequent 47 patients were administered only 3 doses of methylprednisolone days 0, 1, and 2 postoperatively (1, 0.5, and 0.5 g, respectively). Total fasting cholesterol, high-density cholesterol, low-density cholesterol, and triglyceride levels were measured at monthly intervals. Mean serum cholesterol level was significantly greater in CSA patients (200 mg/dL) compared with TAC patients (158 mg/dL; P =.0003). Serum triglyceride levels were more than 2-fold greater with CSA (292 mg/dL) compared with TAC (134 mg/dL; P =.002). Hypercholesterolemia (cholesterol > 240 mg/dL) was present in 10 of 57 patients (18%) and was significantly more common in CSA-treated patients (8 of 27 patients; 30%) compared with TAC-treated patients (2 of 30 patients; 6%; P <.05). Hypertriglyceridemia (serum triglyceride > 300 mg/dL) was present in 10 of 57 patients (18%) and was significantly more common in CSA-treated patients (9 of 27 patients; 33%) compared with TAC-treated patients (1 of 30 patients; 3%; P <.05). We conclude that (1) concomitant use of TAC with RAPA reduces the prevalence and severity of posttransplantation dyslipidemia, and (2) these findings have important implications in the prevention of complications of hypercholesterolemia in liver transplant recipients.
