Recurrence of primary biliary cirrhosis and primary sclerosing cholangitis after liver transplantation in Japan

HEPATOLOGY RESEARCH, Issue 2007
Satoshi Yamagiwa
Although there was some initial controversy, there is now a consensus that primary biliary cirrhosis (PBC) does indeed recur in both cadaveric and living donated allografts. Recurrence rate after deceased donor liver transplantation (LT) was reported to be 10.9,23% at 5 years. In the present study, we reviewed 221 PBC patients who underwent living-donor liver transplantation (LDLT) in Japan. The 5-year overall survival rate was 79%, and the rate of recurrence based on histological findings was 10% (7/70) after a median time of 36 months. Primary immunosuppression, withdrawal of corticosteroids and human leukocyte antigen matches were not associated with the recurrence. Recurrent PBC appears to have little impact on graft function and survival, but this may become a greater problem with longer follow up. It is noteworthy that the 10-year survival of primary sclerosing cholangitis (PSC) patients who underwent LDLT wasfound to be only 39.1% in Japan, whereas that of PBC was 72.9%. Factors associated with the poor prognosis include biliary strictures, hepatobiliary and colorectal malignancies, and recurrence of PSC. In our study, we reviewed 66 patients with PSC who underwent LDLT in Japan. The 5-year survival rate was 72%, and the rate of recurrence diagnosed on histological and cholangiographic findings was 25% (11/44). Well-defined diagnostic criteria and longer studies are required to characterize the nature of recurrent PSC and its impact on graft survival in more detail. [source]

The effect of immunosuppressive regimens on the recurrence of primary biliary cirrhosis after liver transplantation

LIVER TRANSPLANTATION, Issue 7 2003
Josh Levitsky
Recurrence of primary biliary cirrhosis (PBC) has been described in liver transplant recipients. Type of immunosuppression has been reported to influence the frequency of recurrence. The aim of this study is to evaluate the occurrence and pattern of recurrent PBC in our liver transplant recipients and determine any association of immunosuppressive agents with its recurrence. Patients who underwent orthotopic liver transplantation (OLT) for PBC were identified from the University of Chicago Liver Transplant Database. Recurrent PBC was diagnosed based on specific pathological criteria. Of 46 patients who underwent OLT for PBC between 1984 and 2000, a total of 7 patients (15%) were diagnosed with recurrent PBC at a median of 78 months (range, 27 to 120 months) after OLT. Forty-three percent of patients were administered cyclosporine, whereas 57% were administered tacrolimus before disease recurrence. Rates of recurrence were not different between patients maintained on cyclosporine therapy (16%) compared with those maintained on tacrolimus therapy (18%; P = 1.0). There also was no difference in frequency of rejection episodes or duration of corticosteroid therapy between those who did and did not have recurrent PBC. In conclusion, recurrent PBC developed in a small number of patients 2 years or longer after OLT. In our population, there was no difference in recurrence rates between those administered cyclosporine or tacrolimus for immunosuppression. (Liver Transpl 2003;9:733-736.) [source]

Long-term clinical outcome of living-donor liver transplantation for primary biliary cirrhosis

HEPATOLOGY RESEARCH, Issue 2007
Etsuko Hashimoto
Aim:, We described the recurrence of primary biliary cirrhosis (PBC) after living donor liver transplantation (LDLT) (Liver Transplantation, 7, 2001: 588). However, since the follow-up period in that study was insufficiently long (median 35.5 months), we performed a long-term study to further characterize recurrence of PBC after LDLT. Patients:, From 1991 to 2006, 15 patients with end-stage PBC underwent LDLT at Tokyo Women's Medical University. Of these patients, we studied 8 PBC patients (age 29 to 51 years, all females) who survived LDLT for more than 5 years. The follow-up period for these patients ranged form 68 to 120 months. Immunosuppression was maintained with tacrolimus and prednisone. Laboratory examinations performed in every patient and donor before LDLT included routine biochemical studies, antimitochondrial antibody (AMA) by immunofluorescence (IF), anti-M2 by enzyme-linked immunosorbent assay as well as antinuclear antibody (ANA) by IF, and immunoglobulin. After LDLT, the same laboratory examinations were performed in patients every 6 months. Liver biopsy was performed when patients exhibited clinical or biochemical signs of graft dysfunction. In addition, protocol biopsy was performed every 1 to 2 years after LDLT. Results:, At the time of LDLT, all patients had end-stage cholestatic liver failure. Seven patients were positive for AMAand anti-M2 while 1 patient was negative for these markers but strongly positive for ANA. Donors were blood relatives in 6 cases, and 2 donors who were not blood relatives still exhibited multiple HLA matches with the recipients. At the end of the study in May 2006, all patients were doing well. On laboratory examination, mild abnormal liver function test results were found in 4 patients: 3 were probably due to recurrence of PBC, 1 resulted from nonalcoholic steatohepatitis. Comparison of the AMA titer between before LDLT and the most recent follow-up visit showed an increase in three patients, a decrease in two patients and no change in three patients. In contrast, the ANA titer increased in five patients. Histologically, strong evidence of recurrent PBC was found in 4 patients, and findings compatible with PBC were present in 2 additional patients. Conclusions:, Although the number of our patients is small, our findings confirm that PBC can recur at high frequency after LDLT. However, this complication has not developed to advanced stages and has not caused appreciable symptoms in our patients, all of whom have a good quality of life. [source]

The effect of immunosuppressive regimens on the recurrence of primary biliary cirrhosis after liver transplantation

Recurrent primary biliary cirrhosis

Liver transplantation remains the only effective treatment for end-stage primary biliary cirrhosis (PBC). It appears now well accepted that the disease recurs in the allograft. The diagnosis of recurrent PBC is made on the basis of a consistent history and demonstrating the histologic features of PBC on liver biopsy and exclusion of other causes of bile duct damage [source]

Recurrent Primary Biliary Cirrhosis After Liver Transplantation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2010
M. G. Silveira
Recurrent primary biliary cirrhosis (PBC) is an important clinical outcome after liver transplantation (LT) in selected patients. Prevalence rates for recurrent PBC (rPBC) reported by individual LT programs range between 9% and 35%. The diagnostic hallmark of rPBC is histologic identification of granulomatous changes. Clinical and biochemical features are frequently absent with rPBC and cannot be used alone for diagnostic purposes. Some of the risk factors of rPBC may include recipient factors such as age, gender, HLA status and immunosuppression, as well as donor factors such as age, gender and ischemic time, although controversy exists. Most patients have early stage disease at the time of diagnosis, and there may be a role for therapy with ursodeoxycholic acid. While short- and medium-term outcomes remain favorable, especially if compared to patients transplanted for other indications, continued follow-up may identify reduced long-term graft and patient survival.

Cyclosporine A Protects Against Primary Biliary Cirrhosis Recurrence After Liver Transplantation

Primary biliary cirrhosis (PBC) reoccurs in a proportion of patients following liver transplantation (LT). The aims of our study were to evaluate the risk factors associated with PBC recurrence and determine whether recurrent disease constitutes a negative predictor for survival. One hundred and eight patients receiving LT for end-stage PBC were studied. Recurrent disease was diagnosed in 28 patients (26%). Probability of recurrent PBC at 5 years was 13% and 29% at 10 years with an overall incidence of 3.97 cases per 100 patient years. By univariate Cox analysis use of tacrolimus (HR 6.28, 95% CI, 2.44,16.11, p < 0.001) and mycophenolate mofetil (HR 5.21, 95% CI, 1.89,14.33, p = 0.001) were associated with higher risk of recurrence; whereas use of cyclosporine A (CsA) and azathioprine were associated with reduced risk of recurrence (HR 0.13, 95% CI 0.05,0.35, p < 0.001 and HR 0.27, 95% CI 0.11,0.64, p = 0.003, respectively). In the multivariate Cox analysis, only CsA was independently associated with protection against recurrence (HR 0.17, 95% CI 0.06,0.71, p = 0.02). Five-year probability of survival was 83% and 96%, in patients without and with recurrence (log-rank test, p = 0.3). Although PBC transplant recipients receiving CsA have a lower risk of disease recurrence, the development of recurrent PBC did not impact on long-term patient survival. [source]
