Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and fibrosis of the bile ducts, resulting in end-stage liver disease and reduced life expectancy. PSC primarily affects young and middle-aged men, often in association with underlying inflammatory bowel disease. The etiology of PSC includes immune-mediated components and elements of undefined nature. A cholestatic picture of liver biochemistries with elevations in serum alkaline phosphatase, nonspecific autoantibodies such as perinuclear antineutrophilic antibody, antinuclear antibodies and smooth muscle antibodies, and diffuse multifocal biliary strictures, resulting in a 'beaded' appearance on radiographic studies, are the hallmarks of the disease. No effective medical therapy is currently available, although clinical studies are in progress. Ursodeoxycholic acid at high doses (28 mg/kg/day to 30 mg/kg/day) is the most promising agent but is unproven so far. Liver transplantation is currently the only life-extending therapy for patients with end-stage disease, although recurrent disease can be observed in the transplanted liver. The multiple complications of PSC include pruritus, fatigue, vitamin deficiencies, metabolic bone disease, peristomal varices, bacterial cholangitis, dominant biliary strictures, gallbladder stones and polyps, and malignancy, particularly cholangiocarcinoma, which is the most lethal complication of PSC.

Abstract
Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) may all recur after liver transplant. Diagnosis of rPBC is defined by histology; rAIH by serology, biochemistry and histology; rPSC by histology and/or imaging of the biliary tree and exclusion of other causes of nonanastomotic biliary strictures. Criteria for recurrent disease (RD) may differ from those used in similar disease in the native liver: frequent use of immunosuppressive therapy changes the pattern and natural history of RD and can co-exist with other transplant-related causes of graft damage. RD may occur in the presence of normal liver tests; the reported incidence will depend on the way in which diagnostic tests (especially protocol biopsies) are applied. The risk of RD increases with time, but does not correlate with the rate of graft loss. Treatment is largely unproven: ursodeoxycholic acid will improve serology and may slow progression of rPSC and rPBC; introduction or increased dose of corticosteroids may reduce progression of rAIH. Risk factors for rPBC include use of tacrolimus compared with cyclosporine; for rPSC include absence of colon peri-transplantation and for rAIH possible associations with some HLA haplotypes have been suggested.

Abstract
Patients should be considered for liver transplantation if they have evidence of fulminant hepatic failure, a life-threatening systemic complication of liver disease, or a liver-based metabolic defect or, more commonly, cirrhosis with complications such as hepatic encephalopathy, ascites, hepatocellular carcinoma, hepatorenal syndrome, or bleeding caused by portal hypertension. While the complications of cirrhosis can often be managed relatively effectively, they indicate a change in the natural history of the disease that should lead to consideration of liver transplantation. Referral to a liver transplant center is followed by a detailed medical evaluation to ensure that transplantation is technically feasible, medically appropriate, and in the best interest of both the patient and society. Patients approved for transplantation are placed on a national transplant list, although donor organs are allocated locally and regionally. Since 2002, priority for transplantation has been determined by the Model of End-Stage Liver Disease (MELD) score, which provides donor organs to listed patients with the highest estimated short-term mortality.

Abstract
Liver transplantation (LT) is the only therapeutic option for end-stage primary sclerosing cholangitis (PSC), but PSC can recur (rPSC) in some patients after LT. The aim of our study was to evaluate the risk factors associated with rPSC. Between 1989 and 2004, 69 patients receiving transplantation for PSC (42 male, mean age 41.9 yr). Clinical and laboratory data, activity/extension and treatment of ulcerative colitis (UC), post-LT cytomegalovirus (CMV) infection, and immunosuppression were evaluated. Determination of rPSC was made by radiological and histological findings. Exclusion criteria were ABO blood group incompatibility, hepatic artery stenosis, and biliary strictures occurring in <3 months post-LT. A total of 48 (70%) patients had PSC and UC pre-LT. rPSC occurred in 7 of 53 (13.5%, 2 patients with de novo UC) who were alive 1 yr after LT and/or met inclusion/exclusion criteria: median 60 (4-120) months. No patient without post-LT UC had rPSC: 0 of 20 vs. 7 of 26 with post-LT UC (P = 0.027). The multivariate logistic regression analysis showed that maintenance steroids for UC (>3 months) post-LT was the only risk factor significantly associated with rPSC (P = 0.025). In conclusion, the presence of UC post-LT, and the need for maintenance steroids post-LT, which is an independent factor, are associated with rPSC. These findings could help elucidate a possible mechanism of PSC pathogenesis.

Abstract
Orthotopic liver transplantation (OLT) is the only effective treatment for end-stage liver disease due to primary sclerosing cholangitis (PSC). Recurrence of PSC has recently emerged as a leading cause of allograft failure in the long term. There is limited data on risk factors for recurrence of PSC. We performed a retrospective analysis of 69 consecutive patients who underwent a first OLT for PSC over a 14-year period. Baseline characteristics and clinical and laboratory test results post-LT were recorded. Cholangiograms and liver histopathology were reviewed in a blinded manner by an experienced radiologist and hepatopathologist. Recurrent PSC was diagnosed using previously published Mayo Clinic cholangiographic or histologic criteria. Of 69 patients, 7 (10%) developed recurrent PSC at a median of 68 months (range, 24-134 months) post-LT. The following variables were associated with recurrent PSC in our cohort: presence of human leukocyte antigen (HLA)-DRB1*08 (29% versus 2%; P= 0.026; odds ratio [OR], 24.4; 95% confidence interval [CI], 1.8-318.1), acute cellular rejection (ACR) (71% versus 22%; P= 0.015; OR, 8.7; 95% CI, 1.5-49.9), and steroid-resistant ACR (29% versus 0%; P= 0.012). Despite the strong linkage disequilibrium between DRB1*08 and DQB1*04, DRB1*08-positive subjects with recurrence were negative for DQB1*04, whereas the single DRB1*08-positive subject without recurrent PSC was positive for DQB1*04. A history of ACR and presence of HLA-DRB1*08 are associated with increased risk of recurrent PSC, suggesting an immunologic mechanism for this syndrome. Further studies are required to confirm these observations and to understand the underlying mechanisms.

Abstract
Orthotopic liver transplantation (OLT) is the treatment of choice for patients with end-stage primary sclerosing cholangitis (PSC). This study sought to chronicle the natural history of PSC recurrence following OLT and identify clinical variables that may contribute to disease reemergence. From 1988 to 2006, 1102 OLTs were performed in 1032 adults at the University of Colorado Health Sciences Center. Of these, 130 patients (12.6%) with PSC received 146 allografts. Recurrence was defined by a clinically worsening examination and radiographic evidence. A total of 9 potential predictors were considered, using both bivariate log rank and multivariate Cox analysis, including: age > 55, gender, surgical technique (piggyback technique), presence of inflammatory bowel disease, intact colon before transplant, or cholangiocarcinoma (CCA), cold ischemia time, sirolimus-based immunosuppression, and graft type. The 1, 5, and 10-year recurrence-free survival was 91%, 76%, and 61%, respectively. The crude incidence of disease recurrence was 22 of 130 patients or 16.9%. Patients' risk of recurrent PSC at 1, 5, and 10 years was 2%, 12%, and 20%, respectively (mortality censored). Of the 22 patients that developed recurrent disease, 7 received a second transplant. Of the 9 factors considered, the presence of CCA prior to OLT is significantly predictive of disease recurrence [risk ratio (RR) = 3.77; P = 0.0038]. Once a patient was diagnosed with recurrent disease, the median survival without receiving a second transplant was 39.1 months (95% confidence interval: 27.6-50.6 months). In conclusion, recurrent PSC following OLT is a formidable but protracted problem following OLT. Patients may require a second transplant following reemergent disease with reasonable survival benefit.

Abstract
BACKGROUND In orthotopic liver transplantation (OLT) distinct causes of graft failure (GF) and death with a functioning graft (DFG) exist. Prognostic factors for one failure type may be distinctly different from those predictive of other types, and an accurate portrayal of these relationships may more clearly explain each factor's importance. METHODS A multivariable cause-specific hazard (CSH) rate analysis using Cox stepwise regression was performed among 877 adults who received primary OLT during 1996-2004 with tacrolimus+steroids as immunosuppression. RESULTS Older donor age (P=0.004) implied greater primary dysfunction GF, while primary sclerosing cholangitis (PSC; P=0.0002) implied greater vascular thrombosis GF. Recurrent nonmalignant liver disease GF was higher among hepatitis C virus patients (P<0.00001), and younger recipient age (P=0.005) implied greater death from recurrent (metastatic) hepatocellular carcinoma. African-American race (P<0.00001), PSC (P=0.003), and younger recipient age (P=0.005) were independently associated with greater GF due to chronic rejection. Older donor age (P=0.003) implied greater infection DFG, while older recipient age (P=0.003) and pretransplant diabetes (P=0.03) were independently associated with greater cardiovascular/cerebrovascular DFG. Finally, most of these cause-specific predictors were not significant in an overall Cox model for graft survival. CONCLUSIONS The CSH approach should be more widely used in investigations of prognostic factors. The result of older donor age implying greater primary dysfunction GF and infection DFG but having no association with other failure types demonstrates that its impact is specific to the graft's early posttransplant functional status. In addition, while recipient age was an important prognosticator, its direction of association reverses depending upon the outcome being analyzed.

Abstract
Pathology in a liver transplant setting addresses four different topics: establishment of a definite diagnosis of the liver disease before listing for transplantation, evaluation of the donor liver with regard to pre-existing diseases, in particular macrovesicular steatosis and fibrosis, assessment of the hepatectomy specimen, and post-transplant biopsy evaluation. Of these, post-transplant biopsy evaluation is the most challenging and clinically the most relevant issue. It requires fast diagnoses to facilitate specific treatment and it has to incorporate a broad spectrum of differential diagnoses. Precise knowledge about rejection, post-transplant therapy, pathology of immunosuppression, and recurrence of the initially underlying liver disease including the characteristic time peaks and atypical histological presentations (e.g., fibrosing cholestatic hepatitis) is needed to evaluate specific and combined histological pictures of liver damage. For adequate interpretation of post-transplant biopsies the hepatopathologist has to be informed about the essential clinico-anamnestic aspects such as time course, medication, imaging results, and serology.

Abstract
Recurrence of autoimmune liver disease in allografts has long been a topic of debate. We conducted a systematic review of the literature to examine the reported incidence of recurrence after liver transplantation of primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and autoimmune hepatitis (AIH). The MEDLINE, EMBASE, and Cochrane electronic databases were used to identify articles. The inclusion criteria used were articles on patients with at least 90 days of posttransplantation follow-up, histologic criteria for diagnosis of PBC and AIH recurrence, radiologic or histologic criteria or both for diagnosis of PSC recurrence, and exclusion of other causes of liver disease causing similar histologic findings. Incidence in individual studies was combined to calculate the overall recurrence. Risk factors were analyzed whenever crude data were available. Funnel plots were used to assess publication bias. Out of 90 articles identified, 43 met criteria for systematic review (PBC, 16; PSC, 14; AIH, 13). The calculated weighted recurrence rate was 18% for PBC, 11% for PSC, and 22% for AIH. No difference was found in PBC and AIH recurrence by type of primary immunosuppression. There were not enough data to assess this issue in PSC studies. There was evidence of publication bias among PSC and AIH studies but not among PBC studies. In conclusion, recurrence of autoimmune liver disease after liver transplantation appears to be a real concern. As these patients are followed long-term, recurrence of disease may become the primary cause of morbidity.

Abstract
1. Primary sclerosing cholangitis (PSC) in the nontransplant setting is a chronic, progressive liver disease characterized by diffuse stricturing of the biliary tree, cholestatic liver enzymes, and a compatible liver biopsy. 2. Cholangiography reveals irregularity of the bile duct wall, strictures, beading, and diverticula. 3. The typical biopsy reveals inflammation and fibrosis of the interlobular and septal bile ducts, often with obliteration or biliary-type cirrhosis. 4. The precise pathogenetic mechanism remains elusive but is assumed to be an autoimmune phenomenon. 5. For patients with end-stage complications of PSC, such as liver failure, recurrent bacterial cholangitis, and intractable pruritus, liver transplantation is an acceptable treatment option.

Abstract
1. Recurrent primary sclerosing cholangitis (PSC) is extremely difficult, if not impossible, to distinguish from other causes of biliary strictures or sclerosing cholangitis in allografts using needle biopsy evaluation alone. Technical problems with biliary reconstruction, long cold ischemic times, non-heart beating donors, ABO blood group incompatibility, antibody-mediated rejection, and small-for-size syndrome in reduced-size or living donor livers can also cause similar manifestations in a peripheral core biopsy. 2. Some difficulties in distinguishing between sclerosing cholangitis and chronic rejection (CR) arise because: a) at risk populations are similar; b) both can cause "cholestatic" elevation of liver injury tests; and c) both can lead to intrahepatic cholestasis and small bile duct loss. 3. Etiopathogenesis and pathology of CR and sclerosing cholangitis have some overlapping features, but show distinct differences that result in significantly different and discriminating pathologic manifestations. 4. Clues in the clinical history, evaluation of serial biopsies, and histopathology can be used to distinguish with confidence between sclerosing cholangitis and CR. 5. Potential discriminating features include liver size and gross appearance, and histopathology findings in the arterial tree, hilar lymph nodes, large and small bile ducts, interface zone, lobular, and perivenular regions.

Abstract
Primary sclerosing cholangitis (PSC) is a rare but important liver disease that leads to cirrhosis and need for liver transplantation in a high proportion of cases. The disease occurs in approximately 1 per 100,000 population per year, usually presents in adulthood, and affects men more often than women. Typical serum biochemical results, autoantibodies and liver biopsy are suggestive but not diagnostic of PSC, the diagnosis requiring cholangiographic demonstration of stricturing and dilatation of the intra- and/or extra-hepatic bile ducts. The natural history of PSC is variable, the average survival being 12 to 17 years. The cause of PSC is still unknown. Although considered an autoimmune disease, PSC has several atypical features and a strong genetic component. The therapy of PSC is unsatisfactory. Standard doses of ursodeoxycholic acid (UDCA) lead to improvements in biochemical abnormalities but not in histology, cholangiographic appearance or survival. Several innovative therapies have been tried in PSC, but with scant evidence of benefit. For patients with high grade strictures, endoscopic dilatation is beneficial. Liver transplantation is successful for end-stage liver disease due to PSC and improves survival. PSC may recur after transplantation but is rarely progressive. The most dreaded complication of PSC is cholangiocarcinoma. Diagnosis of this highly malignant tumor is difficult, and there are no biomarkers for its early detection. Liver transplantation for cholangiocarcinoma has an exceedingly poor outcome, although transplantation with neoadjuvant chemoirradiation holds promise in selected patients. Thus, significant opportunities remain for basic and clinical research into the cause, natural history, and therapy of PSC.

Abstract
Long-term graft survival and mortality after liver transplantation continue to improve. However, disease recurrence remains a major stumbling block, especially among patients with hepatitis C. Chronic hepatitis C recurs to varying degrees in nearly all patients who undergo transplantation. Transplantation for hepatitis C is associated with higher rates of graft failure and death compared with transplantation for other indications, and retransplantation for hepatitis C related liver failure remains controversial. Recurrence of hepatitis B has been markedly reduced with improved prophylactic regimens. Further, rates of hepatocellular carcinoma recurrence have also decreased, as improved patient selection criteria have prioritized transplantation for those with a low risk of recurrence. Primary biliary cirrhosis recurs in some patients, but it is often relatively mild. Autoimmune liver disease has also been shown to have a relatively benign post-transplantation course, but some studies have indicated that it slowly progresses in most recipients. It has been recently reported that alcoholic liver disease liver transplant recipients who return to drinking have worsened mortality. In such patients worse outcomes are not due to graft failure, but instead to other comorbidities. Recurrences of other diseases, including nonalcoholic steatohepatitis and primary sclerosing cholangitis, are now being recognized as having potentially detrimental effects on graft survival and mortality. Expert clinical management may help prevent and treat complications associated with disease recurrence.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is a chronic cholestatic disease that progresses to end-stage liver disease. There are several specific problems related to the posttransplantation period in these patients. The aim of this study was to analyze a single center experience with 17 orthotopic liver transplantations (OLT) due to PSC. PATIENTS AND METHODS Seventeen patients were included (10 men, 7 women). Actuarial patient and graft survival rates and the incidence of recurrent sclerosing cholangitis were determined at 1, 5, and 7 years. RESULTS Fifteen patients received single grafts, whereas two patients required retransplants. Patients received either cyclosporine (n = 7) or tacrolimus (n = 10) based immunosuppression. The 1-, 5-, and 7-year patient survival rates were 80%, 60%, and 60%, respectively, whereas the graft survival rates were 88%, 65%, and 65%, respectively. Two patients had cholangiocarcinomas (CCA) diagnosed during OLT; both recurred within 6 months and had a fatal outcome. Two patients (12%) developed recurrent sclerosing cholangitis, as assessed by liver histology and imaging of biliary tree. CONCLUSIONS Liver transplantation provides good patient and graft survival rates in cases affected with PSC. CCA is associated with poor recipient survival. Recurrent PSC occurs in approximately 12% of cases but does not significantly affect patient survival.

Abstract
Primary sclerosing cholangitis (PSC) is a well-established indication for orthotopic liver transplantation (OLT), but post-OLT bile duct strictures complicate the outcome for these patients. These strictures might represent recurrent PSC (rPSC). To estimate the risk factors for post-OLT non-anastomotic bile duct strictures in PSC patients and to find their possible etiology, we performed magnetic resonance cholangiography (MRC) and angiography (MRA) in all PSC patients who had undergone OLT and were alive (median follow-up 6.4 years, range 1.4-15.2 years). This group of PSC patients was compared to a group of 45 non-PSC patients who had also undergone OLT. A logistic regression analysis was performed to find predictors of rPSC. Bile duct strictures were found in 19/49 PSC patients and in 4/45 non-PSC patients (P = 0.001). In the PSC group nine patients without other possible explanations for bile duct strictures than rPSC were identified, i.e., the estimated risk of rPSC was 9/49 (18%); surprisingly similar changes were also seen in one patient without a pre-transplant PSC diagnosis. Severe liver disease due to rPSC was seen in 4/9 patients (one patient died and three are being evaluated for re-OLT). Steroid-resistant rejection was the only significant predictor for rPSC. In conclusion, our study shows that by the use of MRC we found more bile duct strictures in PSC patients post-OLT compared to controls and that steroid-resistant rejections was a predictor of such changes.

Abstract
Primary sclerosing cholangitis (PSC) is rare in the pediatric population. Little information exists on the progression of the disease in children. This study evaluated the experience with PSC at the Children's Hospital of Philadelphia over the past 20 years, with an emphasis on the histologic features at presentation, during disease progression, and after liver transplantation. We retrospectively reviewed the medical records of patients diagnosed with PSC between 1981 and 2001. Nineteen patients met the inclusion criteria with classic radiographic evidence of PSC. One additional patient with normal biliary imaging was subsequently diagnosed at the time of liver transplantation. The 20 patients with PSC (14 males) ranged in age from 1 month to 15 years at time of presentation. Inflammatory bowel disease was evident in 50% of patients. Initial histology revealed advanced disease (bridging fibrosis or cirrhosis) in 13 patients and an earlier histologic stage in 7 patients. Of the latter, 3 remain stable, 2 required transplantation, and 2 were lost to follow-up. Seven of the 13 patients with advanced disease required orthotopic liver transplantation, and 3 of these subsequently showed recurrence of primary disease in the allograft. Thus, most subjects presented insidiously at an advanced stage that required transplantation. Subjects who presented at an earlier stage progressed or remained stable, but the histologic findings at diagnosis were generally not predictive of disease progression. Recurrence of PSC after transplantation is a significant complication in children.

Abstract
The management of primary sclerosing cholangitis (PSC) is hindered by incomplete understanding of the pathogenesis of the disease and the lack of good prognostic models. Few large randomized controlled trials of drug therapy have been published. Best practice in the management of PSC is currently based therefore on careful interpretation of the available evidence, close observation of individual patients and clinical experience of the disease. Drug therapy is useful for alleviating symptoms. Ursodeoxycholic acid may slow progression of the disease and reduce the frequency of complications. Consensus is emerging on the issues of screening for the malignant complications of PSC and the indications for liver transplantation are becoming broader and encompassing the earliest stages of cholangiocarcinoma. In view of the rarity of the disease in the general population, large international collaborations to study PSC are necessary to provide clearer answers in areas of uncertainty, and these are now beginning to emerge.

Abstract
Bordetella hinzii was isolated in four biliary specimens collected over 6 months from a liver transplant recipient with cholangitis. The isolates were resistant to most beta-lactam antibiotics and fluoroquinolones. Molecular typing was performed by pulsed-field gel electrophoresis. These data add cholangitis to the spectrum of disease manifestations caused by B. hinzii.

Abstract
UNLABELLED Primary sclerosing cholangitis (PSC) is a chronic cholestatic disease that progresses to end-stage liver disease. This report is a retrospective analysis of a Canadian centre experience with liver transplantation (LT) for PSC. Of 1107 LTs performed between 1984 and 2002, 132 were performed on 111 patients with PSC. Patient survival at 1, 3, 5, and 10 years was 84.5%, 84.5%, 83.4%, and 68.9%, respectively. Graft survival at 1, 3, 5, and 10 years was 80.8%, 79.8%, 72.7%, and 55.3%. These were not significantly different from overall patient survival (P =.91) or graft survival (P =.28) in non-PSC patients transplanted over the same time period. Early mortality was predominantly related to primary nonfunction and multi-organ failure; late mortality was predominantly related to malignancy. No patient with known cholangiocarcinoma (CCA) underwent LT, but three patients had an incidental CCA noted on explant pathology. All three died of widespread metastatic disease (10.8, 38.0, and 39.8 months after LT). Nineteen patients lost their primary grafts requiring retransplantation, and two of these patients required a third transplant. Recurrent PSC was detected in six patients and suspected in another six. Four patients have been retransplanted for recurrent PSC. Chronic rejection was detected in nine patients. Eight have required retransplantation. The incidence of biliary complications was 16.2%. CONCLUSIONS LT is effective therapy for PSC. Patient and graft survival is comparable to that seen in patients transplanted for indications other than PSC, but long-term graft survival may be lower. Recurrent PSC and chronic rejection are the major determinants of graft loss.

Abstract
Cholestasis is a common sequela of liver transplantation. Although the majority of cases remain subclinical, severe cholestasis may be associated with irreversible liver damage, requiring retransplantation. Therefore, it is essential that clinicians be able to identify and treat the syndromes associated with cholestasis. In this review, we consider causes of intrahepatic cholestasis. These may be categorized by time of occurrence, namely, within 6 months of liver transplantation (early) and thereafter (late), although there may be an overlap in their causes. The causes of intrahepatic cholestasis include ischemia/reperfusion injury, bacterial infection, acute cellular rejection, cytomegalovirus infection, small-for-size graft, drugs for hepatotoxicity, intrahepatic biliary strictures, chronic rejection, hepatic artery thrombosis, ABO blood group incompatibility, and recurrent disease. The mechanisms of cholestasis in each category and the clinical presentation, diagnosis, treatment, and outcome are discussed in detail.

Abstract
Primary sclerosing cholangitis (PSC) is the fourth leading diagnosis in liver transplant recipients in the United States. The disease is known to recur in 15% to 30% of liver transplant recipients. We set out to investigate how different immunosuppression regimens affected natural history of PSC after liver transplantation at our center. We reviewed records of all patients who underwent a liver transplantation at our institution in between 1988 and 2000 and had a diagnosis of PSC at the time of liver transplantation. Primary sclerosing cholangitis recurred in 15 of 71 patients (21.1%) who had complete records and survived more than 30 days after liver transplantation. Although recurrence of primary sclerosing cholangitis was most often seen (but not statistically significantly so) in patients who received maintenance corticosteroids, the time to recurrence was not significantly different between those who were treated with maintenance, those who were not successfully weaned, and those who successfully weaned off corticosteroids within 3 months after liver transplantation. Orthoclone (OKT3) therapy (Ortho-Biotech, Inc., Raritan, NJ) was associated with a higher risk of primary sclerosing cholangitis recurrence (29% versus 10%, P <.05). Recurrence was not influenced by immunosuppression with either cyclosporine or tacrolimus. Coexistent inflammatory bowel disease was a cause of failure to wean off corticosteroids, was associated with a shorter time to recurrence of sclerosing cholangitis, and was responsible for significant comorbidity (colon cancer in 7.3%). Primary sclerosing cholangitis recurrence is commonly seen after liver transplantation. More immunosuppression seems to be detrimental to the outcome of our patients with sclerosing cholangitis: use of OKT3 was associated with a greater incidence of recurrence. Length of corticosteroid use did not affect timing or risk of recurrence, and because it has been proven that early corticosteroid withdrawal after liver transplantation is beneficial, we continue to recommend this practice.

Abstract
Orthotopic liver transplantation is the only definitive therapeutic option in patients with primary sclerosing cholangitis (PSC) and end-stage liver disease. However, PSC recurs in up to 20% of patients transplanted for this indication. To date, no patient has been reported to develop cholangiocarcinoma (CCA) post-transplant, without biliary tract cancer having been present pretransplant. Here, we report recurrent PSC complicated by de-novo CCA in a 31-year-old man transplanted for PSC 8 years earlier. Cholangiocarcinoma was confirmed using a combination of computed tomography, cholangiography, positron emission tomography and histological examination of biliary cytology. He has since been successfully re-transplanted following preoperative chemo-radiotherapy. No viable tumor was identified in the explanted liver. This case establishes that long-term complications associated with PSC and biliary-enteric surgery such as CCA may become apparent in new grafts post-transplant.

Abstract
Orthotopic liver transplantation (OLT) has become the only effective therapeutic option for patients with end-stage liver disease caused by primary sclerosing cholangitis (PSC). Excellent long-term outcome has been reported, with 5-year patient survival rates of approximately 80%. In the last few years, increasing evidence has emerged that PSC recurs after OLT. The diagnosis of PSC is based on well-defined cholangiographic features combined with biochemical and histological findings. However, none of these features is specific for PSC, particularly after OLT, because biliary strictures in the liver allograft can occur from a variety of causes other than recurrence. Therefore, PSC recurrence remains a controversial issue, especially because of a lack of a gold standard for diagnosis and well-established diagnostic criteria. Some reports provided cholangiographic evidence that post-OLT biliary strictures occurred more frequently in patients with PSC than in those who underwent OLT for other liver diseases (including patients with a Roux-en-Y biliary reconstruction). Because no other possible cause of biliary strictures could be invoked to explain the greater prevalence of these strictures, recurrent disease has been implicated. There also is histological evidence suggesting that PSC recurs after OLT. Histological findings suggestive of PSC were found more often in PSC allografts compared with a control group. Furthermore, histological features typical for PSC (fibro-obliterative lesions) were seen exclusively in liver biopsy specimens from patients with PSC. Recurrence of PSC was defined in a recent study from the Mayo Clinic by means of strict cholangiographic and histological criteria in a large cohort of patients with PSC in whom other causes of biliary strictures were excluded. PSC recurrence was found in 20% of patients. No risk factor for PSC recurrence could be found, and recurrent disease did not influence patient or graft survival after a mean follow-up of 4.5 years. In conclusion, several studies provided convincing evidence that PSC recurs after OLT, with an incidence of 5% to 20% and an interval to diagnosis of at least 1 year after OLT. To date, patient and graft survival do not appear to be negatively affected by disease recurrence in the intermediate term of follow-up.

Abstract
1. Recurrent primary biliary cirrhosis (PBC) after transplantation is controversial, but most studies support disease recurrence within the graft. 2. Granulomatous destructive cholangitis should be present, and exclusion of acute and chronic rejection, graft-versus-host disease, biliary obstruction, viral hepatitis, and drug effects is mandatory before making a diagnosis of recurrent PBC. 3. Recurrent primary sclerosing cholangitis (PSC) after transplantation is difficult to diagnose because of the lack of a diagnostic gold standard. 4. Well-defined cholangiographic and histological criteria should be present, and exclusion of preservation injury, blood group type incompatibility between donor and recipient, chronic rejection, hepatic arterial occlusion, and viral infection is mandatory before making a diagnosis of recurrent PSC. 5. Most studies support recurrent autoimmune hepatitis (AIH) after transplantation based on clinical, biochemical, serological, and histological criteria. Exclusion of rejection, viral infection, drug effects, and biliary obstruction is mandatory before making a diagnosis of recurrent AIH. 6. Intermediate-term patient and graft survival are excellent for patients with recurrent autoimmune liver diseases within the transplanted liver, but additional studies are required to address the impact of disease recurrence on long-term patient and graft survival.

Abstract
1. Lifelong monitoring of graft function, immunosuppressive levels, and screening for drug toxicity is required in all liver recipients. 2. Late hepatic allograft dysfunction is common and is caused by a variety of etiologies including rejection, infection, biliary/vascular abnormalities, recurrence of disease, and drug hepatotoxicity. 3. In all patients with late hepatic allograft dysfunction, liver biopsy should be performed to assess for the presence of rejection, and to thus avoid excessive use of bolus corticosteroid therapy and guide appropriate immunosuppressive management. 4. Recurrence of disease is the most common cause of late hepatic allograft dysfunction. 5. Hepatitis C universally reinfects the hepatic allograft, and is associated with decreased patient and graft survival and leads to the recurrence of cirrhosis in 28% of patients within 5 years of transplantation. 6. Major advances have been made in preventing recurrence of hepatitis B by the use of hepatitis B immune globulin in combination with lamivudine therapy. 7. Autoimmune liver diseases such as primary biliary cirrhosis, primary sclerosing cholangitis, and autoimmune hepatitis have a recurrence rate of approximately 20% to 30%. 8. In patients developing recurrence of autoimmune hepatitis, steroid withdrawal is the most common cause. 9. Recurrent hepatocellular cancer can be markedly reduced if strict guidelines are adhered to in selecting patients. 10. Drug hepatotoxicity must always be considered in the differential diagnosis of late hepatic allograft dysfunction.

Abstract
Over the past decade, the outcome of liver transplantation in primary sclerosing cholangitis (PSC) patients with end-stage liver disease has improved significantly with many centres reporting 1-year patient and graft survival of 90-97% and 85-88%, respectively. Based on these results, liver transplantation has emerged as the treatment of choice for PSC patients. Specific complications related to PSC remain problematical. Inflammatory bowel disease (IBD) occurs in 70% of patients, and there is a distinctly increased risk of colorectal neoplasia both pre- and post-transplantation. Furthermore, symptoms related to IBD post-transplantation can become severe and lead to the need for proctocolectomy. Cholangiocarcinoma remains a major risk facing the PSC patient and develops in 15-30% of patients. Markers to detect the early neoplastic changes of cholangiocarcinoma are not available. To date, outcome following liver transplantation in PSC patients who have associated cholangiocarcinoma has been dismal. However, those patients who are found to have an incidental cholangiocarcinoma have an acceptable low incidence of recurrence of disease. To assess optimal timing of liver transplantation, natural history risk scores have been developed and utilized. Utilizing such risk scores, estimated survival for the individual PSC patient can be obtained. Finally, there is an increased incidence of both acute and chronic rejection, hepatic artery thrombosis and biliary stricturing in PSC patients undergoing liver transplantation. A late rise in serum alkaline phosphatase level is almost always indicative of biliary stricturing and recurrence of disease. Approximately 20% of patients followed for 5 years or more will have recurrence of PSC documented both on cholangiography and histology.

Abstract
Tacrolimus has proven to be a potent immunosuppressive agent in liver transplantation (LT). Its introduction has led to significantly less frequent and severe acute rejection. Little is known about the rate of chronic rejection (CR) in primary LT using tacrolimus therapy. The aim of the present study is to examine the long-term incidence of CR, risk factors, prognostic factors, and outcome after CR. The present study evaluated the development of CR in 1,048 consecutive adult primary liver allograft recipients initiated and mostly maintained on tacrolimus-based immunosuppressive therapy. They were evaluated with a mean follow-up of 77.3 +/- 14.7 months (range, 50.7 to 100.1 months). To assess the impact of primary diagnosis on the rate and outcome of CR, the population was divided into 3 groups. Group I included patients with hepatitis C virus (HCV)- or hepatitis B virus (HBV)-induced cirrhosis (n = 312); group II included patients diagnosed with primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), or autoimmune hepatitis (AIH; n = 217); and group III included patients with all other diagnoses (n = 519). Overall, 32 of 1,048 patients (3.1%) developed CR. This represented 13 (4.1%), 12 (5.5%), and 7 patients (1.3%) in groups I, II, and III, respectively. The relative risk for developing CR was 3.2 times greater for group I and 4.3 times greater for group II compared with group III. This difference was statistically significant (P =.004). The incidence of acute rejection and total number of acute rejection episodes were significantly greater in patients who developed CR compared with those who did not (P <.0001). Similarly, the mean donor age for CR was significantly older than for patients without CR (43.0 v 36.2 years; P =.02). Thirteen of the 32 patients (40.6%) who developed CR retained their original grafts for a mean period of 54 +/- 25 months after diagnosis. Seven patients (21.9%) underwent re-LT, and 12 patients (38.3%) died. Serum bilirubin levels and the presence of arteriopathy, arterial loss, and duct loss on liver biopsy at the time of diagnosis of CR were significantly greater among the 3 groups of patients. In addition, patient and graft survival for group I were significantly worse compared with groups II and III. We conclude that CR occurred rarely among patients maintained long term on tacrolimus-based immunosuppressive therapy. When steroid use is controlled, the incidence of acute rejection, mean donor age, HBV- and/or HCV-induced cirrhosis, or a diagnosis of PBC, PSC, or AIH were found to be predictors of CR. Greater values for serum bilirubin level, duct loss, arteriopathy, arteriolar loss, and presence of HCV or HBV were found to be poor prognostic factors for the 3 groups; greater total serum bilirubin value (P =.05) was the only factor found to be significant between patients who had graft loss versus those who recovered.

Abstract
The diagnosis and management of autoimmune hepatitis continues to evolve as new diagnostic tests and new therapies are added to the armamentarium. Also encouraging are the advances in the understanding of the human immune system and its involvement in the origin and course of auto immune diseases in general and in the variants of autoimmune liver disease. Promising changes are expected in the next few years as new medications become available to the practicing hepatologist. New immune tests may allow therapies to be customized to patients, and antiviral therapies may also eventually be used in the management of this autoimmune liver diseases.

Abstract
Recurrence of primary sclerosing cholangitis (PSC) after liver transplantation is very uncommon. The true incidence of recurrence is unknown, mainly because of the difficulty in differentiating ischemic strictures from that of recurrent disease. Primary sclerosing cholangitis and ischemic strictures have identical histopathologic and cholangiographic features. We report a young man who had recurrence of PSC in two allografts and report our experience in 32 patients who had liver transplantation for PSC. Six patients (18%) had evidence of non-anastomotic strictures and, of these, only one patient (reported here) had unequivocal evidence of true recurrence. The strictures in other five patients happened because of ischemia. The recurrence of the disease in two allografts in an immunosuppressed patient, in the absence of ischemia, chronic rejection, or any known pathogen, raises the question of the role of an unidentified infectious agent in the etiopathogenesis of PSC.

Abstract
Successful liver transplantation in a child is often a hard-won victory, requiring all the combined expertise of a dedicated pediatric transplant team. This article outlines the considerable challenges still facing pediatric liver transplant physicians and surgeons. In looking to the future, where should priorities lie to enhance the success already achieved? First, solutions to the donor shortage must be sought aggressively by increasing the use of from split-liver transplants, judicious application of living-donor programs, and increasing the donation rate, perhaps by innovative means. The major immunologic barriers, to successful xenotransplantation make it unlikely that this option will be tenable in the near future. Second, current immunosuppression is nonspecific, toxic, and unable to be individually adjusted to the patient's immune response. The goal of achieving donor-specific tolerance will require new consideration of induction protocols. Developing a clinically applicable method to measure the recipient's immunoreactivity is of paramount importance, for future studies of new immunosuppressive strategies and to address the immediate concern of long-term over-immunosuppression. The inclusion of pediatric patients in new protocols will require the ongoing insistence of pediatric transplant investigators. Third, the current immunosuppressive drugs have a long-term morbidity and mortality of their own. These long-term effects are particularly important in children who may well have decades of exposure to these therapies. There is now some understanding of their long-term renal toxicity and the risk of malignancy. New drugs may obviate renal toxicity, whereas the risk of malignancy is inherent in any nonspecific immunosuppressive regimen. Although progress is being made in preventing and recognizing PTLD, this entity remains an important ongoing concern. The global effect of long-term immunosuppression on the child's growth, development, and intellectual potential is unknown. Of particular concern is the potential for neurotoxicity from the calcineurin inhibitors. Fourth, recurrent disease and new diseases, perhaps potentiated by immunosuppressive drugs, must be considered. Already the recurrence of autoimmune disease and cryptogenic cirrhosis have been documented in pediatric patients. Now, a new lesion, a nonspecific hepatitis, sometimes with positive autoimmune markers, that may progress to cirrhosis has been recognized. It is not known whether this entity is an unusual form of rejection, an unrecognized viral infection, or a response to immunosuppressive drugs themselves. Finally, pediatric transplant recipients, like any other children, must be protected and nourished physically and mentally if they are to fulfill their potential. After liver transplantation the child's growth, intellectual functioning, and psychologic adaptation may all require special attention from parents, teachers, and physicians alike. There is limited understanding of how the enormous physical intervention of a liver transplantation affects a child's cognitive and psychologic function as the child progresses through life. The persons caring for these children have the difficult responsibility of providing services to evaluate these essential measures of children's health over the long term and to intervene if necessary. Part of the transplant physician's our duty to protect and advocate for children is to fight for equal access to health care. In most of the developing world, economic pressures make it impossible to consider liver transplantation a health care priority. In the United States and in other countries with the medical infrastructure to support liver transplantation, however, health care professionals must strive to be sure that the policies governing candidacy for transplantation and allocation of organs are applied justly and uniformly to all children whose lives are threatened by liver disease. In the current regulatory climate that increasingly takes medical decisions out of the hands of physicians, pediatricians must be even more prepared to protect the unique and often complicated needs of children both before and after transplantation. Only in this way can the challenges of the present and the future be met.

Abstract
The current treatment of posttransplant lymphoproliferative disease (PTLD) includes prophylaxis at the time of transplant, decreasing or stopping immunosuppresion and initiation of antiviral therapy in patients with polymerase chain reaction or clinical evidence of PTLD, and judicial reintroduction of immunosuppression in patients who have cleared their PTLD and have begun to have rejection. The pharmacology, pharmacokinetics, notable side effects, and toxicities of the immunosuppressive agents are described in this article. At the conclusion of each section the author's current practice with these agents and treatment strategies are described.

Abstract
Liver transplantation is the only effective therapeutic option for patients with end-stage liver disease due to primary sclerosing cholangitis (PSC). In this study, we analyzed a single center's experience with 150 consecutive PSC patients who received 174 liver allografts. Mean follow-up was 55 months. Actuarial patient survival at 1, 2, 5, and 10 years was 93.7%, 92.2%, 86.4%, and 69.8%, respectively, whereas graft survival was 83.4%, 83.4%, 79.0%, and 60. 5%, respectively. The main indication for retransplantation was hepatic artery thrombosis, and the major cause of death was severe infection. Patients with PSC had a higher incidence of acute cellular and chronic ductopenic rejection compared to a non-PSC control group. Chronic ductopenic rejection adversely affected patient and graft survival. Biliary strictures, both anastomotic and nonanastomotic, were frequent and occurred in 16.2% and 27.2% of patients, respectively. The incidence of recurrent PSC was 20%. A negative impact on patient survival was not seen in patients with either postoperative biliary strictures or recurrence of PSC. Six patients (4%) had cholangiocarcinoma and 1 patient died related to recurrence of malignant disease. Seventy-eight percent of PSC patients had associated inflammatory bowel disease, most commonly chronic ulcerative colitis, which did not adversely impact patient outcome posttransplantation. Nine patients required proctocolectomy after liver transplantation; 5 because of intractable symptoms related to inflammatory bowel disease and 4 due to the development of colorectal carcinoma/high-grade dysplasia. Our data show that liver transplantation provides excellent long-term patient and graft survival for patients with end-stage PSC.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease that progresses to death as a result of liver failure or cholangiocarcinoma. Susceptibility to PSC is associated with the HLA A1-B8-DR3 haplotype, and new associations with HLA C and tumor necrosis factor genes have been detected. A circulating antineutrophil cytoplasmic antibody is found in many patients with PSC, but its antigen or antigens have not been identified. Some studies suggest that this antigen may be an anti-nuclear membrane protein rather than cytoplasmic. Diagnosis of PSC is based on endoscopic retrograde cholangiography, but magnetic resonance cholangiography is a promising noninvasive alternative. Medical treatment remains elusive. In highly selected patients, endoscopic or even surgical treatment can be tried. Orthotopic liver transplantation remains the only effective therapy, but inflammatory bowel disease may run a more aggressive clinical course after this procedure. Sclerosing cholangitis may recur after transplantation, but this has had no clinical implications to date.

Abstract
Chronic hepatic allograft rejection is characterized by the histological findings of ductopenia and a decreased number of hepatic arteries in portal tracts in the presence of foam cell (obliterative) arteriopathy. Recent studies have extended the histological spectrum of chronic rejection to include the presence of biliary epithelial atrophy or pyknosis involving the majority of small ducts present in the liver biopsy specimen. Overall, the incidence of chronic rejection in adults appears to be decreasing and is currently approximately 4%. However, the incidence of chronic rejection in pediatric liver transplant recipients has been more stable and ranges from 8% to 12% in most studies. Clinical risk factors associated with chronic rejection include: underlying liver disease, HLA donor-recipient matching, positive lymphocytotoxic cross-match, cytomegalovirus infection, recipient age, donor-recipient ethnic origin, male donor into female recipient, number of acute rejection episodes, histological severity of acute rejection episodes, low cyclosporine trough levels, and retransplantation for chronic rejection. Chronic rejection, once diagnosed, frequently leads to graft failure; however, a number of reports indicated 20% to 30% of the patients with this diagnosis may respond to additional immunosuppressive therapy or even resolve spontaneously receiving baseline immunosuppression. Newer immunosuppressive agents, such as tacrolimus and mycophenolate, may successfully reverse chronic rejection, particularly when it is diagnosed in its early histological stages.
