Abstract
BACKGROUND In 2004, four recipients of kidneys, a liver, and an arterial segment from a common organ donor died of encephalitis of an unknown cause. METHODS We reviewed the medical records of the organ donor and the recipients. Blood, cerebrospinal fluid, and tissues from the recipients were tested with a variety of assays and pathological stains for numerous causes of encephalitis. Samples from the recipients were also inoculated into mice. RESULTS The organ donor had been healthy before having a subarachnoid hemorrhage that led to his death. Encephalitis developed in all four recipients within 30 days after transplantation and was accompanied by rapid neurologic deterioration characterized by agitated delirium, seizures, respiratory failure, and coma. They died an average of 13 days after the onset of neurologic symptoms. Mice inoculated with samples from the affected patients became ill seven to eight days later, and electron microscopy of central nervous system (CNS) tissue demonstrated rhabdovirus particles. Rabies-specific immunohistochemical and direct fluorescence antibody staining demonstrated rabies virus in multiple tissues from all recipients. Cytoplasmic inclusions consistent with Negri bodies were seen in CNS tissue from all recipients. Antibodies against rabies virus were present in three of the four recipients and the donor. The donor had told others of being bitten by a bat. CONCLUSIONS This report documenting the transmission of rabies virus from an organ donor to multiple recipients underscores the challenges of preventing and detecting transmission of unusual pathogens through transplantation.

Abstract
BACKGROUND Acute renal failure developing after orthotopic liver transplantation (OLTx) requiring renal replacement heralds a poor prognosis. Our center has previously reported a 1-year survival of only 41.8%. We undertook this study to determine whether we could identify preoperative and perioperative factors that would predict which patients are at risk. METHODS OLTxs performed between January 1, 1996, and December 31, 2001, were included in our retrospective database review. Combined kidney-liver transplants or patients with preoperative renal replacement therapy (RRT) were excluded. A total of 724 OLTxs were studied, which were divided into group I: no RRT, n=637; group II: hemodialysis only post-OLTx, n=17; and group III: continuous RRT post-OLTx, n=70. Univariate and stepwise logistic multivariate analyses were performed. RESULTS Preoperative serum creatinine greater than 1.9 mg/dL (odds ratio [OR] 3.57), preoperative blood urea nitrogen greater than 27 mg/dL (OR 2.68), intensive care unit stay more than 3 days (OR 10.23), and Model for End-Stage Liver Disease score greater than 21 (OR 2.5) were significant. A clinical prediction model was constructed: probability of requiring dialysis posttransplant=(-2.4586+1.2726 [creatinine >1.9] + 0.9858 [blood urea nitrogen >27] + 0.4574 [Model for End-Stage Liver Disease score >21] + 1.1625 [intensive care unit days >3]). A clinical prediction rule for patients with a score greater than 0.12 was applied to OLTx recipients who underwent transplantation in 2002. A total of 15 of 20 patients who received RRT and 111 of 121 who did not were correctly classified with the model. CONCLUSIONS This model allowed us to identify patients at high risk for developing the need for RRT postoperatively. Strategies for these patients to prevent or ameliorate acute renal failure and reduce the need for RRT postoperatively are needed.

Abstract
Hepatitis C virus (HCV)-induced cirrhosis is the commonest indication for orthotopic liver transplantation, but HCV recurrence is nearly universal and may worsen patient / graft outcomes. The frequency and severity of HCV recurrence has apparently increased in recent years, raising concern about a possible role for newer immunosuppression regimens in this increase, including potentially tacrolimus. We randomized 79 patients to receive tacrolimus or cyclosporine as primary immunosuppressant posttransplantation. A pathologist blinded to treatment reviewed serial liver biopsies. Month 12 cumulative probabilities of histological hepatitis C recurrence for tacrolimus- and cyclosporine-treated patients were .38 and .54 (P = .19) and failure / death were .25 and .28, respectively (P = .789). Although cyclosporine-treated patients had significantly larger increases in median serum HCV RNA levels (months 1, 6, and 12), no significant differences were observed between the two treatment arms in histologically-diagnosed HCV recurrence / survival rates. In conclusion, choice of calcineurin inhibitors does not impact severity of recurrent HCV.

Abstract
Two-stage total hepatectomy and liver transplantation has been reported for acute liver disease such as fulminant hepatic failure, primary graft failure, severe hepatic trauma, and spontaneous hepatic rupture secondary to hemolysis, elevated liver function tests, low platelets syndrome, and preeclampsia. This is the first report of patients with cirrhosis to undergo a 2-stage total hepatectomy and liver transplantation. From 1984 to 2002, our institution performed 2008 orthotopic liver transplantations. We identified 4 patients with chronic liver disease who underwent a 2-stage hepatectomy and liver transplantation. This is a retrospective review of these 4 patients and a review of the literature on this procedure. All 4 patients were young men with an age range of 29-31 years and had underlying cirrhosis as well as a previous transjugular intrahepatic portosystemic shunt (TIPS)procedure. Acute decompensation fulfilling Ringes' criteria for toxic liver syndrome secondary to an upper gastrointestinal bleed occurred in all patients. The approximate average time between hepatectomy and liver transplantation was 20 hours (range: 8-42 hours). In all cases, the explanted liver showed histological changes of acute hepatic necrosis within the background of cirrhosis. After hepatectomy, vasopressor requirements were well documented in 2 patients. For 1 patient, there was a clear improvement in their hemodynamic status. The mean hospital stay of the 4 patients was 63 days. All patients were discharged from the hospital and are alive and well with adequate liver function at 6 to 37 months follow-up. Two-stage total hepatectomy and liver transplantation may be a life-saving procedure in highly selected cirrhotic patients with acute hepatic decompensation and multiorgan dysfunction.

Abstract
The most significant development in liver transplantation in the USA over the past year was the full implementation of the MELD- and PELD-based allocation policy in March 2002, which shifted emphasis from waiting time within broad medical urgency status to prioritization by risk of waiting list death. The implementation of this system has led to a decrease in pretransplant mortality without increasing post-transplant mortality, despite a higher severity of illness at the time of transplant. The trend over the last few years of rapidly increasing numbers of adult living donor liver transplants was reversed in 2002 by a decline of more than 30% in the number of these procedures. In 2002, a greater percentage of women received livers from living donors (43%) than deceased donors (34%), possibly because of size considerations. From 1993 to 2001, the waiting list increased more than sixfold, from 2902 patients to 18,047 patients. For the first time since 1993, the waiting list size decreased in 2002, dropping 6% to 16,974 candidates. The percentage of temporarily inactive liver candidates also increased from 2001, thus the net decrease in the active waiting list for 2002 was 12%. This may reflect a trend toward less pre-emptive listing practices under MELD. Intestine transplantation remains a low-volume procedure limited to a few transplant centers and is still accompanied by significant pre- and post-transplantation risks. As this procedure matures, its application may increase to include recipients at an earlier stage of their disease with better likelihood of success.

Abstract
The ability to estimate rather than measure the glomerular filtration rate (GFR) in patients before and after liver transplantation would be helpful in estimating risk, dosing drugs, and assessing long-term toxicity of calcineurin inhibitors. Currently available equations for estimating the GFR have not been validated in either the pre- or post-liver transplant population. We have evaluated the performance of currently used formulas for the estimation of the GFR in this setting. Data were collected prospectively on patients who underwent liver transplantation between 1984 and 2001. GFR per 1.73 m2 was measured by I125 iothalamate in patients at the pretransplant evaluation and at 3 months, 1 year, and yearly posttransplant thereafter. GFR estimated by the Cockcroft-Gault equation, the Nankivell equation, and the equations from the Modification of Diet in Renal Disease (MDRD) Study (6, 5, and 4 variables) was compared with the measured GFR. Pretransplant GFR was available in 1,447 patients. The mean GFR was 90.7 +/- 40.5 mL/min. Values for r and r2 were highest for the MDRD Study 6-variable equation (0.70 and 0.49, respectively). Only 66% of estimates were within 30% of the measured GFR. At 3 months, 1 year, and 5 years posttransplant, the mean GFR was 59.5 +/- 27.1 mL/min, 62.7 +/- 27.8 mL/min, and 55.3 +/- 26.1 mL/min, respectively. Values for r and r(2) for the MDRD Study 6-variable equations at 1 and 5 years posttransplant were 0.74 (0.55) and 0.76 (0.58), respectively. At these time points, however, only 67% and 64% of the estimated GFR were within 30% of the measured GFR. MDRD Study equations had greater precision than other equations, but the precision was lower than reported for MDRD estimation of GFR in other populations. Better methods for estimating the GFR are required for evaluation of renal function before and after liver transplantation.

Abstract
OBJECTIVE To compare the degree of societal reintegration between alcohol-related and non-alcohol-related liver transplant recipients. SUMMARY BACKGROUND DATA Orthotopic liver transplantation (OLTX) is the treatment of choice for end-stage liver disease of various etiologies. Returning patients to society to lead active and productive lives is a key goal of OLTX. METHODS A questionnaire assessing societal reintegration was administered by phone to 84 alcoholic liver disease (ALD) OLTX recipients (ALDs) and 68 non-ALD OLTX recipients having undergone OLTX at a single-center urban not-for-profit teaching hospital. Sixty-eight non-ALD OLTX recipients, serving as the control group (Controls), were matched to the ALDs by age, sex, and length of follow-up. Participation levels were assessed in the following areas: employment, homemaking, academic study, support of others through financial and/or care-giving efforts, and involvement in social or community groups and activities. RESULTS Seventy-nine percent of ALDs and 81% of Controls were male. Median age was 53 years for ALDs and 54 years for Controls. Median length of follow-up for both groups separately was 52 months. No significant differences were noted between ALDs and Controls in the proportion of employed individuals, homemakers, students, and supporters of others. Controls were significantly more likely than ALDs to be involved in structured social activities and routine volunteer work. CONCLUSIONS Alcohol-related and non-alcohol-related OLTX recipients appear to return to society to lead similarly active and productive lives. ALD OLTX recipients appear less likely to be involved in structured social activities and routine volunteer work than non-ALD OLTX recipients.

Abstract
BACKGROUND Recurrent disease after liver transplant is a significant problem. Recurrent primary biliary cirrhosis (RPBC) is a histologic diagnosis. Clinical data is unreliable in predicting or diagnosing recurrence. RPBC appears to have a changing clinical presentation in recent years. MATERIALS AND METHODS The diagnosis of RPBC after liver transplantation was made histologically. Data were obtained from our prospectively maintained liver-transplant database and evaluated statistically. RESULTS Between 1985 and 1999, 1,835 liver transplants were performed, 169 for PBC. One hundred fifty-six patients were evaluated (one patient received retransplantation, and 13 were excluded). Seventeen (10.9%) experienced recurrence. Median posttransplantation follow-up time was 72.1 months. Median time to recurrence was 49.6 months. Median follow-up time after recurrence was 11.5 months. Neither acute rejection episodes (P=0.34) nor OKT3 use (P=0.36) before diagnosis of recurrence was significant. The combination of cyclosporine, azathioprine, and prednisolone demonstrated recurrence in 6 of 71 (8.4%). Six of 49 (12.2%) patients treated with cyclosporine with or without mycophenolate mofetil and prednisolone experienced recurrence. Six of 36 (16.7%) patients treated with tacrolimus and prednisolone with or without mycophenolate mofetil experienced recurrence. Patients treated with cyclosporine had numerically fewer recurrences than those treated with tacrolimus (P=0.11). CONCLUSIONS Patients with RPBC demonstrated prolonged survival. Clinical factors did not aid in predicting RPBC. The clinical course of RPBC appears to be different than in the earlier years of liver transplantation. Immunosuppression may play a role. The use and type of antimetabolite drugs had no affect on recurrence. RPBC demonstrated a different clinical course with tacrolimus treatment (shorter time to recurrence) and increased incidence when compared with cyclosporine treatment. Controlled randomized studies are necessary to determine differences between tacrolimus and cyclosporine treatment, if any.

Abstract
As the Baylor Regional Transplant Institute celebrates its 20-year anniversary and the transplant of its 2,500th liver, the program has continued to grow, reaching its highest yearly volume to date. Twenty years gives an excellent opportunity to see how the facets of our program have adjusted in response to changes in both society and our own field of transplantation. Our recipient and donor demographics have changed significantly, but despite older recipients, older and more marginal donors and the issues of disease recurrence, we have consistently improved survival of both the patient and graft, reduced rejection rates and minimized hospital and ICU stays. These survival improvements have been even more pronounced in patients transplanted for HCC. Because of constantly changing risk and complication patterns, we have continually analyzed and adapted our processes and protocols, adjusting them in response to patient outcomes and the best current scientific evidence when needed. The research at Baylor has always had a practical, clinical dimension, but with development of our "Genes of Health" program at the Baylor Institute of Immunology Research, we hope to expand more basic science transplant research and most importantly take the lead in translational research.

Abstract
Hypocalcemia in patients with cirrhosis may be due to a number of causes. We noted a relationship between injection with gadodiamide, a particular gadolinium chelate, during magnetic resonance imaging of the liver and the development of a falsely low serum total calcium level in a patient with cirrhosis. A cross-reference and retrospective chart review identified 10 additional patients in whom this phenomenon was noted. We describe the temporal relationship and clinical characteristics of these patients. Pseudohypocalcemia following magnetic resonance imaging with gadodiamide contrast should be considered in the differential diagnosis of hypocalcemia in patients with cirrhosis.

Abstract
Orthotopic liver transplantation (OLT) is the treatment of choice for end-stage liver disease of various etiologies. Its use, however, remains limited due to the scarcity of donor organs. Measures to assess health-related quality of life (HRQOL) are increasingly being implemented to examine the efficacy of medical therapies involving scarce resources. HRQOL was assessed and compared between 88 male and 61 female patients before and after liver transplantation. Data were gathered from subjects having completed a questionnaire pre-OLT, and again at 1 year and 2 years post-OLT. This questionnaire, developed specifically for OLT patients, contains at its core questions derived from several well-established instruments measuring health status and HRQOL. Male OLT recipients reported a higher degree of overall HRQOL than that reported by female OLT recipients, both before and after OLT. When controlling for disparity in education between the sexes, findings revealed that among the lesser educated (< or =12 years), men and women scored similarly, while among the more educated (>12 years), men scored higher than women. Employment findings revealed a higher percentage of men working before transplant and at 1-year post-OLT when compared with women. At 2 years post-OLT, men and women exhibited similar employment rates. Male OLT recipients report a higher level of overall HRQOL than that reported by female OLT recipients, both before and after liver transplantation. Education appears to significantly affect HRQOL and may account for, at least in part, differences in reported HRQOL between male and female OLT recipients.

Abstract
The Model of End-Stage Liver Disease (MELD) score, an accurate predictor of mortality in patients awaiting liver transplantation (OLTX), did not predict graft or patient survival in the post-transplant setting. Our aim was to test the model in patients who underwent OLTX for chronic hepatitis C. Two hundred and eighty-seven adult patients who underwent primary OLTX for chronic hepatitis C between December 1993 and September 1999 were studied from a prospectively maintained database. The group was stratified by MELD scores of less than 15, 15-24, and greater than 24. Patient survival, graft survival, and interval liver biopsy pathology were reviewed. Both patient and graft survival at 3, 6, and 12 months were significantly lower in the higher MELD score groups, as was patient survival at 24 months (p-values, 0.01-0.05). The difference in survival between the low, medium, and high MELD score groups increases in time. The survival without bridging fibrosis in the allograft at 1 year post-transplant was significantly lower with higher MELD scores (p = 0.037). The decrease in survival seen in hepatitis C patients with MELD scores greater than 24 raises questions of transplant suitability for these patients. Therapeutic modalities to decrease post-transplant graft injury in these patients should be explored.

Abstract
The most common hepatic complications of cystic fibrosis (CF) are steatosis, fibrosis, biliary cirrhosis, atretic gallbladder, cholelithiasis, and sclerosing cholangitis. Cholestatic liver disease is a slow progressive disorder, but will stabilize for many patients. CF patients may suffer from the consequences of their liver disease and without liver transplantation, variceal hemorrhage, malnutrition, or end-stage liver disease can lead to death. Prospective data were collected and reviewed on 311 liver transplants performed in 283 patients at the Children's Medical Center of Dallas between October 1984 and November 2000. Ten children received an orthotopic liver transplant (OTLX) for end-stage liver disease associated with cystic fibrosis. Pulmonary function tests were obtained preoperatively in all cases. There were nine boys and one girl. Six are currently alive, and four are dead. Both patient and graft survival was 5.75 yr. Among those currently alive, mean patient and graft survival is 7.71 yr (range 0.10-12.62 yr). Mean patient and graft survival of those who died was 2.35 yr (range 0.78-5.33 yr). No survivor required re-transplantation and currently, all have normal serum aminotransferase values. Chronic sinusitis was not a significant pre- or post-transplant morbidity, although systematic radiographic evaluation of the sinuses did not occur. Pulmonary deaths occurred in three patients from pulmonary hemorrhage, pulmonary infection with Aspergillus and Candida glabrata, and acute bronchopneumonia associated with polymicrobial sepsis because of Pseudomonas, Klebsiella, and Candida albicans 1.44, 0.78, and 1.83 yr, respectively, after transplantation. The fourth death was associated with chronic rejection, and occurred 5.33 yr after transplantation. All non-survivors were below the 5th percentile for height and weight at the time of liver transplantation. Mean age at transplantation was 9.72 yr (range 1.23-19.09, median 9.61). Survivors were transplanted at a younger age than non-survivors (mean of 9.21 yr vs. 10.66 yr), and had shorter waiting times from diagnosis of end-stage liver disease to transplantation (6.87 months vs. 13.83 months). Eighty percentage (n = 8) of patients had pretransplant variceal bleeds (83% of survivors, 75% of non-survivors). While all non-survivors had a history of meconium ileus and preoperative need of pancreatic enzymes, only 67% of those alive experienced these complications. Preoperative forced vital capacity FVC was 103% for survivors and 95% for non-survivors. The corresponding numbers for forced expiratory flow (FEF) 25-75 were 74-84% respectively. Preoperative Aspergillus was identified in 30% of patients (n = 3). Two of these patients are alive. Cystic fibrosis constitutes an indication for 3.5% of pediatric liver transplants. Evaluation and transplantation for end-stage liver disease associated with cystic fibrosis should be undertaken at an early age. Most deaths were associated with pulmonary/septic events, and occurred less than 2 yr after OLTX. Those children who did not survive had poor growth and nutrition, prolonged waiting times prior to transplantation, were transplanted at an older age, and had a higher incidence of pancreatic insufficiency and meconium ileus. The presence of Aspergillus in the sputum does not constitute a contraindication for OLTX.

Abstract
The Model for End-Stage Liver Disease (MELD) score is now the criteria for allocation in liver transplantation for patients with chronic disease. Although the score has been effective in the prediction of mortality in patients awaiting liver transplantation, its abilities to predict posttransplantation outcome need study. The aim of this study is to compare outcome in the first 2 years after liver transplantation according to the pretransplantation MELD score. The study includes 669 consecutive patients who underwent primary liver transplantation between December 1993 and October 1999 in a single transplant center. Patients who died of malignancy were excluded from the series. Pretransplantation MELD score was calculated using the United Network for Organ Sharing formula. Patients were stratified according to MELD score less than 15, 15 to 24, and 25 and higher. Posttransplantation survival at 3, 6, 12, 18, and 24 months was significantly lower in the groups with a higher MELD score. The difference was significant for hepatitis C and noncholestatic liver diseases, but not cholestatic diseases. In patients with a MELD score between 15 and 24, survival was significantly greater with cholestatic diseases and lower in patients with hepatitis C. In our study, pretransplantation MELD score correlates with survival in the first 2 years after transplantation. There is a survival advantage for patients with cholestatic diseases compared with those with hepatitis C. These findings suggest the need to readjust MELD score-based allocation decisions to consider patient outcome.

Abstract
Ovarian cancer is the gynecologic malignancy with the highest number of deaths in the United States. Previous studies had found a decreased incidence of female gynecological malignancies after liver transplantation. In order to estimate the incidence of ovarian carcinoma after liver transplantation, we evaluated 1708 consecutive liver transplant recipients from 1984 to 2001. Of them, 770 (43%) were female. Routine follow-ups were performed at 1, 2, 5, and 10 years after transplantation. There were two cases of ovarian carcinoma. Both occurred in recipients with a previous history of breast cancer. Based on these data, we conclude that the incidence of ovarian cancer is 1:385 among all female liver transplant recipients, and 1:6.5 among those with a history of pretransplant breast cancer. We recommend that regular check-ups should be undertaken, especially in the population at highest risk.

Abstract
HTLV I and II are unusual retroviruses associated with multiple neurologic and hematologic disorders. We observed an unusually high incidence of HTLV I-II seropositivity among young and middle-aged female organ donors, especially among those in the peripartum period. Ethical issues may arise when informing the families as well as when deciding whether to use organs from these donors. Further confirmatory tests may be difficult to obtain because of time and economic constraints associated with organ procurement.

Abstract
BACKGROUND Patients who undergo orthotopic liver transplantation (OLT) for Budd-Chiari syndrome (BCS) traditionally have been anticoagulated with warfarin postoperatively. Because a significant proportion of BCS patients are found to have an underlying myeloproliferative disorder (MPD), antiplatelet therapy may be a more rational treatment strategy for this subgroup. METHODS All patients who underwent OLT for the diagnosis of BCS at our institution through March 2000 were included in this analysis. Posttransplant therapy consisted of hydroxyurea and aspirin for those with MPDs. Standard anticoagulation or no antithrombotic treatment was given to BCS patients with other causes. Major posttransplantation complications (thrombosis and bleeding) and mortality were determined. RESULTS Seventeen patients underwent OLT for BCS at our institution. The mean follow-up was 68.4 months. Two of seventeen patients died; one patient died of recurrent thrombosis (124 months after OLT) and the other patient died of acute hepatitis B (7 months after OLT). Twelve patients (71%) had evidence of a MPD. Two of the MPD patients were treated with warfarin before the initiation of hydroxyurea and aspirin therapy. The remaining 10 MPD patients were placed on only hydroxyurea and aspirin after OLT. Anagrelide was used in place of hydroxyurea in two patients because of cytopenias caused by the latter agent. The mean follow-up of this group of 10 patients was 59.9 months. Only one patient experienced recurrent thrombosis, which occurred more than 10 years after the original transplant. There were no major bleeding complications and posttransplant liver biopsies were well tolerated. CONCLUSIONS Antiplatelet therapy that consists of hydroxyurea and aspirin is a safe and effective alternative to anticoagulation to prevent recurrent thrombosis in MPD patients with BCS after liver transplantation. For patients with a hypercoagulable state corrected by OLT, antithrombotic therapy probably is not required. For those patients with conditions not corrected by OLT or with idiopathic BCS, anticoagulation or other therapy to control the hypercoagulable state should be given.

Abstract
Hepatocellular carcinoma is an epithelial tumor derived from hepatocytes that accounts for more than 80% of all primary hepatic tumors. The severity of the underlying disease is almost always the key factor in deciding whether to consider liver resection or transplantation as its treatment. Data in our registry corresponding to almost 800 patients from transplant centers throughout the world showed that patient survival after liver transplantation was significantly affected by histologic grade, tumor size >5 cm, and the presence of positive nodes. Recurrence-free survival showed a correlation with tumor size >5 cm, positive nodes, bilobar spread, and vascular invasion. At the present time, 59% of patients in our registry are alive, 84% of whom are free of tumor. Of those who died, half did so without evidence of tumor.

Abstract
The purpose of our study was to evaluate the outcome of children who underwent liver transplantation as treatment for unresectable hepatoblastoma. We prospectively collected data on 311 consecutive liver transplants performed at Children's Medical Center of Dallas between October 1984 and November 2000. There were nine recipients (five boys, four girls) with a diagnosis of unresectable hepatoblastoma. Postoperative survival of those currently alive ranged from 6 months to 16 years (mean 6.4 years, median 7.7 years). All recipients received preoperative chemotherapy: 67% received postoperative chemotherapy. Mean AFP level prior to transplantation was 1 448000 ng/mL. Mean age at diagnosis was 0.81 years. Mean age at transplantation was 1.87 years. Only two patients experienced acute cellular rejection in the postoperative period. There was a total of three deaths and one recurrence. The only instance in which AFP levels did not decrease to low or undetectable levels post-transplantation was in the patient with recurrent tumor. Liver transplantation has an established role in the treatment of hepatoblastoma. It accounted for 3% of pediatric liver transplants, and provided the only opportunity for survival in otherwise incurable patients. Early diagnosis and treatment were found to be associated with better results. Response to chemotherapy may be an important factor influencing survival. Rising AFP levels after transplantation are associated with recurrence.

Abstract
We prospectively collected data on 1,429 liver transplant recipients between December 1984 and December 1998. Fifty-five patients (3.8%; 10 men, 45 women; median age, 44.5 +/- 13 [SD] years) with autoimmune hepatitis (AIH) underwent orthotopic liver transplantation (OLT). Transplant recipients with AIH were younger, more likely to be women, and had a greater likelihood of rejection in the first 3, 6, and 12 months. There was no difference in patient survival or graft survival. There were 11 biopsy-proven recurrences (1 man, 10 women) of AIH after OLT. Almost half the episodes occurred within the first year after OLT. No patient required re-OLT because of recurrent disease. AIH has an incidence of 4% and a recurrence rate of 20% in OLT. Transplant recipients are more likely to be young women and have an increased incidence of acute cellular rejection (ACR) during the first post-OLT year. Recurrence should be suspected in those with abnormal liver function test results in the absence of ACR, especially during the first year after OLT. We cannot establish with certainty whether the observed process represents recurrence of the original autoimmune disease, an alloimmune phenomenon, or allograft dysfunction mimicking AIH.

Abstract
BACKGROUND Alpha-1-antitrypsin (A1AT) deficiency is the most common inherited metabolic disorder with the potential to cause injury in the lung and liver. Recent reports suggested that alpha-1-antichymotrypsin (A1AC) deficiency may also be a possible cause of chronic liver disease. However, it has received little attention and is rarely investigated in the clinical setting. AIMS To assess the role of A1AC deficiency in the pathogenesis of chronic liver disease in two siblings with heterozygous A1AT phenotype Pi SZ. PATIENTS Two adult siblings with an A1AT Pi SZ phenotype and reduced levels of A1AC consistent with heterozygosity who developed cirrhosis and underwent liver transplantation. METHODS AND RESULTS A1AT and A1AC levels in plasma measured by electroimmunoassay were 74 mg/dl and 90 mg/dl (140-470) and 0.12 mg/ml and 0.14 mg/ml (0.173-0.46), respectively. Immunohistochemistry revealed an apparent accumulation of both A1AT and A1AC in hepatocytes. A previously reported point mutation in exon III (Pro(229) to Ala substitution) of the A1AC gene was not detected by polymerase chain reaction amplification and a single strand conformation polymorphism analysis. CONCLUSIONS Our report represents the first case of two siblings with A1CA phenotype Pi SZ who developed cirrhosis and underwent liver transplantation. Both siblings were heterozygous for A1AT and A1AC deficiency suggesting that combined deficiency of these two major serine protease inhibitors may enhance the risk of developing liver disease.
