In living donor liver transplantation (LDLT) for primary biliary cirrhosis (PBC), the majority of donors are genetically related to their recipients, leading to concerns of an earlier recurrence of PBC and a poorer prognosis due to genetic susceptibility. Totally 81 patients who underwent LDLT for PBC were the subjects of the present study. Immunosuppressive agents consisted of tacrolimus and methylprednisolone. In the outpatient clinic, when the aspartate and alanine aminotransferase level exceeded the upper limit of the normal range, the dose of methylprednisolone was increased from 4 to 6 mg/day for several months. Blood was examined every 2 weeks for 3 months and a liver biopsy was performed when aminotransferase levels did not decrease to the upper limit of the normal range after more than 3 months. Five-year survival and recurrence rates were estimated and the prognostic factors were analyzed. The mean observation period was 6.2 years. Five years after LDLT for PBC, the biopsy-proven PBC recurrence rate was 1%. The 5-year patient survival rate was 80%. The nonrelated or blood-related donor factor and number of human leukocyte antigen matches did not correlate with prognosis. PBC recurrence rate after LDLT in our series was lower than that in previous studies. 相似文献

The factors that influence long‐term outcomes after living‐donor liver transplantation (LDLT) for primary biliary cirrhosis (PBC) are not well known. Compared with deceased‐donor transplantation, LDLT has an increased likelihood of a related donor and a decreased number of human leukocyte antigen (HLA) mismatches. To clarify the effects of donor relatedness and HLA mismatch on the outcomes after LDLT, we retrospectively analyzed 444 Japanese patients. Donors were blood relatives for 332 patients, spouses for 105, and “other” for 7. The number of HLA A‐B‐DR mismatches was none to two in 141, three in 123, and four to six in 106 patients. The 15‐year survival rate was 52.6%, and PBC recurred in 65 patients. Recipient aged 61 years or older, HLA mismatches of four or more (maximum of six), graft:recipient weight ratio less than 0.8, and husband donor were adverse indicators of patient survival. IgM 554 mg/dL or greater, donor–recipient sex mismatch, and initial immunosuppression with cyclosporine were significant risks for PBC recurrence, which did not affect patient survival. In subgroup analysis, conversion to cyclosporine from tacrolimus within 1 year diminished recurrence. Prospective studies are needed to determine the influence of pregnancy‐associated sensitization and to establish an optimal immunosuppressive regimen in LDLT patients. 相似文献

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.) 相似文献

Liver transplantation for primary biliary cirrhosis: influence of primary immunosuppression on survival 总被引:4,自引:0,他引:4
INTRODUCTION: Liver transplantation is the only established curative therapy for end-stage primary biliary cirrhosis (PBC). However, the influence of primary immunosuppression on long-term patient and graft survival is still controversial. PATIENTS AND METHODS: Among 1372 patients who underwent liver transplantation from April 1989 to January 2001, 95 (6.9%) suffered from PBC. The primary immunosuppression consisted of cyclosporine (CyA; n = 56) and tacrolimus (FK; n = 39). RESULTS: The median survival of all PBC patients at 5 years was 92% and at 10 years, 90%. There was no difference between the two primary immunosuppression agents. Seven patients died, including five in the cyclosporine group (median = 25 months) and two in the tacrolimus cohort (median = 37 months). One CyA patient group died due to PBC recurrence. Seven patients underwent retransplantation without any difference in primary immunosuppression (CyA 7%; FK 10%). Fifty patients developed an acute rejection episode (CyA 57%; FK 46%); 2 patients, chronic rejection (CyA 2%; FK 4%). Fifty-five patients developed AMA titers after liver transplantation (CyA 66%; FK 46%). Patients presented cyclosporine-based regimens showed significantly (P = .001) more side effects. CONCLUSION: Long-term follow-up after liver transplantation for PBC shows excellent organ and patient survival. The choice of the primary immunsuppressant had no significant influence on patient survival, PBC-related graft loss, or development of acute or chronic rejection episodes. 相似文献

Tacrolimus-based immunosuppression is currently accepted as mainstream therapy in many transplant centers worldwide due to its potent immunosuppressive activity compared to cyclosporine. A tacrolimus-based regimen has been successfully used for our living donor liver transplantation (LDLT) recipients. Adverse effects such as neurotoxicity, nephrotoxicity, and new-onset diabetes mellitus, however, have limited its clinical application. In deceased donor liver transplantation, cyclosporine rescue therapy is valuable for such complications, but few reports have described a strategy for conversion in LDLT. Herein, we present our experience of conversion from tacrolimus to cyclosporine therapy in adult LDLT recipients. Among 203 recipients, 37 patients (18%) required conversion, primarily for neurotoxicity (41%), diabetes mellitus (16%), hematopoietic disorder (16%), and gastrointestinal intolerance (11%). Primary adverse events resolved within 2 months after conversion in 35/37 (94%) of the patients. For LDLT recipients unable to maintain effective immunosuppression with tacrolimus, conversion to cyclosporine is an effective option. 相似文献

Patient selection criteria of deceased donor liver transplantation for primary biliary cirrhosis (PBC) are almost completely established. The aim of this study was to establish selection criteria for both patients and donors of living donor liver transplantation (LDLT) for PBC. We used univariate and multivariate analyses to examine patient and donor characteristics of our first 50 cases of LDLT for PBC to elucidate factors that significantly impacted patient survival or disease recurrence after LDLT in the univariate and/or multivariate analyses. Multivariate analysis demonstrated that the presence of persistent ascites before LDLT, a higher number of human leukocyte antigen (HLA)-A, -B, and -DR mismatches between donor and recipient, and donor age >or=50 years were factors significantly associated with early posttransplant death. Independent risk factors for PBC recurrence after LDLT were a lower number of HLA mismatches between donor and recipient, and a lower average trough level of tacrolimus within 1 year after LDLT. Specifically, the lower the number of HLA-A, -B, and -DR mismatches or the average trough level of tacrolimus within 1 year after LDLT, the higher the possibility of developing a recurrence of PBC. In conclusion, the absence of persistent ascites before LDLT, a lower number of HLA-A, -B, and -DR mismatches between donor and recipient, and a younger donor (<50 years) are preferred for gaining acceptable survival outcomes for the transplant. However, a lower number of HLA-A, -B, and -DR mismatches between donor and recipient may be a risk factor for PBC recurrence. 相似文献

The changing clinical presentation of recurrent primary biliary cirrhosis after liver transplantation 总被引:2,自引:0,他引:2

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. 相似文献

Long-term follow-up after recurrence of primary biliary cirrhosis after liver transplantation in 100 patients 总被引:4,自引:0,他引:4

Orthotopic liver transplantation (OLT) is the only effective curative therapy for end-stage primary biliary cirrhosis (PBC). Survival after OLT is excellent, although recent data have shown a recurrence rate of PBC of up to 32% after transplantation. The aim of this study is to investigate the course after disease recurrence, particularly with regard to liver function and survival in a long-term follow-up. Between April 1989 and April 2003, 1,553 liver transplantations were performed in 1,415 patients at the Charité, Virchow Clinic. Protocol liver biopsies were taken after one, three, five, seven, 10 and 13 yr. One hundred (7%) patients suffered from histologically proven PBC. Primary immunosuppression consisted of cyclosporine (n = 54) or tacrolimus (Tac) (n = 46). Immediately after OLT, all patients received ursodeoxycholic acid. Corticosteroids were withdrawn three to six months after OLT. The median age of the 85 women and 15 men was 55 yr (range 25-66 yr). The median follow-up after liver transplantation was 118 months (range 16-187 months) and after recurrence 30 months (range 4-79 months). Actuarial patient survival after five, 10 and 15 yr was 87, 84 and 82% respectively. Ten patients (10%) died after a median survival time of 32 months. Two of these patients developed organ dysfunction owing to recurrence of PBC. Histological recurrence was found in 14 patients (14%) after a median time of 61 months (range 36-122 months). Patients with Tac immunosuppression developed PBC recurrence more often (p < 0.05) and also earlier (p < 0.05). Fifty-seven patients developed an acute rejection and two patients a chronic rejection episode. Liver function did not alter within the first five yr after histologically proven PBC recurrence. Multivariate analysis of the investigated patients showed that the recipient's age and Tac immunosuppression were significant risk factors for PBC recurrence. Long-term follow-up of up to 15 yr after liver transplantation, owing to PBC, in addition to maintenance of liver function, shows excellent organ and patient survival rates. Although protocol liver biopsies revealed histological recurrence in 14 (14%) patients, only two patients developed graft dysfunction. Tac-treated patients showed more frequently and also earlier histologically proven PBC recurrence; however, in our population we could not observe an impact on graft dysfunction and patient's survival. 相似文献

Two recent brief reports suggest that recipients of living donor liver transplants achieve higher levels of immunosuppressive agents than cadaveric (CAD) liver transplant recipients administered the same dose. These results could have important implications regarding the dosing of immunosuppressives in living donor liver transplant recipients. We report our findings relative to immunosuppressive doses and levels in a cohort of 46 living donor liver transplant recipients. Immunosuppressive blood levels and doses were recorded weeks 1, 2, 3, and 4 and months 2, 3, 4, 5, and 6 for 46 living donor liver transplant recipients and 66 matched CAD liver transplant recipients who underwent transplantation between August 1997 and May 2001. The ratio of level to dose also was recorded at each interval. The mean overall cyclosporine A dose was similar in living donor liver transplant recipients (323 mg/d) compared with CAD recipients (344 mg/d; P = not significant [NS]). The mean overall tacrolimus dose was 15% lower in patients who underwent living donor liver transplantation (LDLT; 5.7 mg/d) than CAD transplantation (6.7 mg/d), although statistical significance was not achieved (P = .08). The mean overall cyclosporine A level was 18% higher in those undergoing LDLT (275 ng/mL) than CAD transplantation (234 ng/mL; P = .015). The mean overall tacrolimus level was the same in living donor liver transplant recipients (10.8 ng/mL) and CAD recipients (10.2 ng/mL; P = NS). The overall cyclosporine A level-dose ratio was 26% higher for those undergoing LDLT (0.83) than CAD transplantation (0.66; P = .01). The overall tacrolimus level-dose ratio was 26% higher for those undergoing LDLT (1.82) than CAD transplantation (1.44; P = .01). In conclusion, (1) living donor liver transplant recipients achieve higher blood levels of tacrolimus and cyclosporine A for a given dose compared with CAD recipients, and (2) this difference is observed up to 6 months after transplantation, when hepatic regeneration is completed.

Thrombotic microangiopathy (TMA) is a rare but potentially lethal complication encountered in solid organ and bone marrow
transplant recipients that requires rapid recognition, diagnosis, and initiation of therapy. Several causes have been identified,
including viral infections and various medications. We report a case of TMA after living-donor liver transplantation (LDLT).
A 60-year-old man underwent LDLT for end-stage liver disease secondary to hepatitis C virus. After 6 months, he required re-transplantation
because graft failure was caused by a small-for-size graft. The immunosuppressive regimen for the second transplantation consisted
of tacrolimus and prednisolone; cyclosporine (CsA), mycophenolate mofetil, and prednisolone had been used for the first transplantation.
Despite multiple transfusions of packed red blood cells and concentrated platelets, his hemoglobin and platelets decreased
and lactate dehydrogenase increased following re-transplantation. Hematological evaluation revealed findings consistent with
TMA. As soon as TMA was diagnosed, the calcineurin inhibitor (CNI) was changed from tacrolimus to CsA, and fresh frozen plasma
(FFP) was given. The patient’s platelets gradually increased after the CNI was changed, and no transfusions were needed. Therefore,
tacrolimus was suspected as the cause of the patient’s TMA. Early diagnosis, switching CNIs, and FFP supplementation allowed
the TMA to resolve without the need for plasma exchange. 相似文献

With the current immunosuppressive regimens, graft loss secondary to immunological reasons after successful liver transplantation is a rarity; acute rejections, however, do occur, with the majority of them being steroid-responsive. The aim of the present study is to examine the rate of acute rejection with tacrolimus, intravenous (IV) mycophenolate mofetil (MMF), and steroids in primary deceased donor liver transplant (DDLT) and live donor liver transplant (LDLT) recipients. During the year 2005, 130 patients (mean age: 54.9 +/- 10.8, males: 84, females: 46, 112 DDLT and 18 LDLT) received primary liver transplantation. They were followed up for the incidence of acute rejection in the first 12 months. Liver biopsies were performed as clinically indicated; protocol liver biopsies were never performed. A total of 127 liver biopsies were performed. Thirty-two had a rejection activity index (RAI) score of > or =3, of which 24 biopsies in 20 patients were not treated with a steroid bolus. Eight (6.1%) patients (mean RAI score: 5.1 +/- 1.4) received 750 to 1500 mg of methylprednisolone over 3 days. Out of these, 2 were noncompliant, 4 were off MMF, and 1 was on cyclosporine. All patients responded to steroid therapy. None of the patients required any antibody preparation. In conclusion, IV MMF with tacrolimus and steroids is useful and required antirejection therapy in 6.1% of liver transplant recipients. 相似文献

ABO‐incompatibility is a major obstacle to expanding exiguous donor pools in adult liver transplantation, especially in countries where grafts from deceased donors are uncommon. We present our preliminary results of ABO‐incompatible (ABO‐I) adult living donor liver transplantation (LDLT) using a new, simple protocol. Seven consecutive cases of ABO‐I LDLT were managed by the same protocol including pre‐operative administration of a single dose of rituximab (375 mg/m2) followed by three to five sessions of plasma exchange before LDLT without portal infusion therapy. The triple immunosuppression protocol consisted of tacrolimus, mycophenolate mofetil and steroids, with mycophenolate mofetil starting seven d before LDLT. Splenectomy was performed for all cases. All patients are alive (100% survival) with a mean follow‐up of 852 d (715–990 d). Neither antibody‐mediated nor hyperacute rejection were encountered. There was only one episode of mild acute cellular rejection, for which steroid augmentation was effective. The median preformed isoagglutinin antibody titer before plasma exchange was 256, while the median antibody titer immediately before LDLT was 16. In conclusion, adult ABO‐I LDLT results were excellent – comparable or even superior to those of ABO‐compatible LDLT. ABO‐I adult LDLT has now become a more applicable modality without the need for an appropriate donor. 相似文献

Interferon (IFN), which is the only possible agent for recurrent hepatitis C after liver transplantation, may cause serious immune-related disorders. We report a case of de novo autoimmune hepatitis (AIH), which developed subsequent to switching from 2b pegylated interferon-α (peg-IFN) to 2a peg-IFN after living donor liver transplantation (LDLT). A 51-year-old man with hepatitis C-associated liver cirrhosis underwent LDLT. About 13 months after the initiation of antiviral therapy, in the form of type 2b peg-IFN with ribavirin, a negative serum hepatitis C virus (HCV)-RNA titer was confirmed. Thereafter, the 2b peg-IFN was switched to 2a peg-IFN, 3 months after which severe liver dysfunction developed, despite a constantly negative HCV-RNA. Liver biopsy showed portal and periportal inflammatory infiltrates including numerous plasma cells, indicating AIH. He was treated with steroid pulse treatment, followed by high-level immunosuppression maintenance, but eventually died of Pneumocystis pneumonitis 4 months after the diagnosis of de novo AIH. 相似文献

Summary Although living donor liver transplantation (LDLT) is accepted as an alternative therapy for primary biliary cirrhosis (PBC), the postoperative results are not well known. Fifty patients with PBC underwent LDLT at Tokyo University Hospital. Their clinical records were retrospectively analyzed. Postoperative death occurred in four patients within 2 months (mortality, 8%), while later death occurred in three patients. In the median follow-up period of 35 months (range 4-84 months), the 1, 3, and 5-year overall survival rates were 90%, 88%, and 80%, respectively. The laboratory data indicated that graft function was sufficient. No recurrence of PBC was confirmed. Multivariate analysis indicated that an updated Mayo score of <10 was a significantly favorable factor for short hospitalization (hazard ratio, 9.52; 95% confidence interval, 1.14-79.5; P = 0.03). In conclusion, LDLT provides a satisfactory long-term survival with the PBC patients. 相似文献

INTRODUCTION: An ABO-incompatible (ABO-I) living donor liver transplantation (LDLT) is a challenge. Until 2000 systemic multidrug immunosuppression and splenectomy was the gold standard with poor results. Application of local administration with prostagrandin E1 (PGE1) and steroids via a portal vein (PV) catheter dramatically improved the survival from 20% to 60% but PV thrombus became a problem (35%). To solve it, an hepatic arterial (HA) catheter was used instead of a PV catheter and splenectomy was omitted. Although the PV thrombus problem was resolved, the ABO antibody titers significantly increased, and two cases of uncontrollable humoral rejection (HR) were experienced. In this study, Rituximab was introduced instead of splenectomy to decrease the antibody. We report the efficacy of prophylaxis with Rituximab for ABO-I LDLT. METHODS: Eight patients received. Rituximab at 2 to 14 days before LDLT. During the operation, the spleen was preserved. Methylpredonisolone and PGE1 were administered via an HA catheter for 2 to 3 weeks after LDLT in addition to an immunosuppressive regimen consisting of tacrolimus and steroids. Antibody titers were measured serially. RESULT: There was no clinical HR. Two patients died of complications unrelated to HR. The antibody titer decreased compared to patients without splenectomy/rituximab. B cells (CD19) were depleted from peripheral blood for up to 3 months. Cytomegalovirus infections were decreased compared to patients with splenectomy (P = .085). CONCLUSION: Rituximab prophylaxis and HA infusion therapy prevented clinical HR, which may provide a breakthrough to overcome the ABO blood-type barrier in liver transplantation. 相似文献

BackgroundTacrolimus-related neurotoxicity is a serious complication. Posterior reversible encephalopathy syndrome, which is severe neurotoxicity after pediatric living donor liver transplantation (LDLT), is a medication-induced complication related to calcineurin inhibitors. The purpose of this study was to evaluate the long-term outcome of tacrolimus-related neurotoxicity after pediatric LDLT.MethodsPediatric patients who underwent LDLT between 2007 and 2020 at our institution and developed neurologic symptoms with tacrolimus were included in the study. Tacrolimus-related encephalopathy was defined as encephalopathy that resolved after tacrolimus was discontinued. All patients received tacrolimus and a steroid for immunosuppression starting just after LDLT.ResultsDuring the study period, 128 patients underwent LDLT. All patients received tacrolimus and a steroid. Six patients (5%) developed tacrolimus-related encephalopathy. The median age at transplant was 1.6 years. The original diseases were biliary atresia (n = 5) and progressive familial intrahepatic cholangiopathy type 2 (n = 1). Patients developed encephalopathy at a median of 9 days after LDLT. All patients recovered with conversion to cyclosporine. Posterior reversible encephalopathy syndrome was confirmed by magnetic resonance imaging in 3 patients. The mean tacrolimus level at encephalopathy was 11 ng/dL (range, 5.6-14.6 ng/dL). White blood cell count elevation was observed in all patients. One patient died of pancreatitis. Surviving patients (n = 5) were followed for a median of 9 years. All patients resumed tacrolimus a median of 8 months from onset. No neurologic complications were observed after resuming tacrolimus.ConclusionWe observed tacrolimus-induced encephalopathy in 5% of patients after pediatric LDLT. Patients can resume tacrolimus safely without further neurologic symptoms. 相似文献

Anti-CD25 and tacrolimus therapy may not prevent early primary biliary cirrhosis recurrence after liver transplantation: two case reports 总被引:1,自引:0,他引:1

Primary biliary cirrhosis (PBC) is an immune-mediated disorder of unknown cause characterized by progressive destruction of intrahepatic bile ducts and the presence of antimitochondrial antibodies. There is no known cure for PBC, and treatment generally includes various combinations of ursodeoxycholic acid and immunosuppressive agents. However, in most patients with end-stage PBC, liver transplantation offers a good quality of life. Recurrent PBC after transplantation is controversial, because most patients with suspected recurrent disease are asymptomatic. Antimitochondrial antibodies frequently persist and do not correlate with disease recurrence. However, most studies support disease recurrence within the graft. The effects of immunosuppression may modify or delay disease expression within the graft. If PBC recurs, intermediate-term patient and graft survivals are excellent, but the long-term outcome remains unknown. Many immunosuppressive agents have been studied with regard to their anti-recurrence properties; however, no standard therapy has been established for this group of patients. In this study we present two patients transplanted for PBC who displayed early recurrence of disease confirmed by liver biopsy and elevated serum AMA. Both individuals received the same immunosuppressive regimen. The data suggest that two doses of daclizumab and tacrolimus monotherapy in the early posttransplant period is insufficient to prevent recurrence of PBC. Addition of glucocorticoids may have beneficial effects in these patients. 相似文献

BackgroundAlthough primary biliary cholangitis (PBC) is considered a good indication for living-donor liver transplantation (LDLT), the postoperative results are not well known.MethodsAt Jikei University Hospital, 14 patients with PBC underwent LDLT from February 2007 to June 2022. We consider PBC with a Model for End-Stage Liver Disease (MELD) score of <20 to indicate LDLT. We performed a retrospective analysis of the patients’ clinical records.ResultsThe patients’ median age was 53 years, and 12 of the 14 patients were female. A right graft was used in 5 patients, and 3 ABO-incompatible transplants were performed. The living donors were children in 6 cases, partners in 4 cases, and siblings in 4 cases. The preoperative MELD scores ranged from 11 to 19 (median, 15). The graft-to-recipient weight ratio ranged from 0.8 to 1.1 (median, 1.0). The median operative time for donors and recipients was 481 and 712 minutes, respectively. The median operative blood loss of donors and recipients was 173 and 1,800 mL, respectively. The median postoperative hospital stay of donors and recipients was 10 and 28 days, respectively. All recipients recovered satisfactorily and remained well during a median follow-up of 7.3 years. Three patients underwent a liver biopsy after LDLT because of acute cellular rejection without histologic findings of PBC recurrence.ConclusionsLiving-donor liver transplantation provides satisfactory long-term survival for patients with PBC with a graft-to-recipient weight ratio of >0.7 and MELD score of <20 without hepatocellular damage and only portal vein hypertension. 相似文献

Relative adrenal insufficiency is now a well-known clinical condition that occurs in critically ill patients particularly with septic complication. However, this pathology has long been unrecognized until recently in liver transplantation patients, for whom postoperative immunosuppressive therapies almost always comprise corticosteroids. We report an obvious case of relative adrenal insufficiency manifested by severe multiple organ dysfunction in a recipient after living donor liver transplantation (LDLT). A 38-year-old woman with multiple hepatocellular carcinoma developed refractory liver failure 2 months after the completion of the dual treatment; namely a cytoreductive right hepatectomy for bulky main tumors followed by 2 courses of percutaneous isolated hepatic perfusion for residual tumors in the remnant liver. She underwent a right-lobe LDLT, and postoperative immunosuppression was initiated with a low-dose tacrolimus monotherapy without corticosteroid because of a severe septic condition before transplantation. Postoperatively, she developed progressive hyperbilirubinemia, renal dysfunction, and coagulopathy. As the corticotropin stimulation test suggested the relative adrenal insufficiency, corticosteroid was commenced 40 days after LDLT. Thereafter, multiple organ dysfunction resolved dramatically and promptly. The patient is presently alive and well with completely normalized liver function 45 months after LDLT. 相似文献
