We aimed to assess the prevalence and consequences of post-transplant DM (PTDM) in Chinese patients with HBV-related liver diseases and to determine the possible risk factors. METHODS: Altogether 165 patients with HBV infection and undergoing cadaveric related liver transplantation (LT) were enrolled. The clinical data of patients with (PTDM group) and without PTDM (non-PTDM group) were compared. RESULTS: Of the 165 patients, 28 had DM and 12 had impaired fasting glucose (IFG) before LT. Patients with pre-transplant DM or IFG had a survival rate similar to that of the others. Forty patients (24.2%) developed PTDM with a mean time of 36 17 days (range 2-300 days) after LT. Of those, 32 developed PTDM within 3 months post-LT and 29 needed insulin treatment. Pre-transplant hepatic encephalopathy and tacrolimus application were found more frequently in the PTDM group than in the non-PTDM group. The plasma tacrolimus levels were notably higher at I and 3 months post-LT in the PTDM group than those in the non-PTDM group. Compared to the non-PTDM group, the PTDM group showed remarkably poorer survival and tumor-free survival in patients with hepatocellular carcinoma, and significantly higher incidence of sepsis, fungal infection, chronic kidney diseases and biliary complications after LT. CONCLUSIONS: Pre-transplant DM did not affect the patient survival after LT. Since PTDM is common, it has a negative impact on outcome and may contribute to tumor recurrence. Pre-transplant hepatic encephalopathy, a tacrolimus-based regimen, and high levels of tacrolimus are clearly associated with the occurrence of PTDM.展开更多

However, the exact influencing factors of AKI are still unclear and a predictive model is desperately required in the clinic. METHODS: Data of 102 consecutive LTs were reviewed. A model for predicting AKI was established and further validated in a prospective study of 44-patients receiving LT. RESULTS: The incidence of AKI was 32.4%. AKI patients showed a significantly lower survival rate than non-AKI patients. Multivariate analysis demonstrated the independent influencing factors of AKI were preoperative serum creatinine >1.2 mg/dl, intraoperative urine output <= 60 ml/h, intraoperative hypotension status, and intraoperative use of noradrenaline. A model was then established and showed a sensitivity of 75.0%, a specificity of 93.8%, and an accuracy of 88.6% in predicting AKI. CONCLUSIONS: High preoperative serum creatinine, low intraoperative urine output, and intraoperative hypotension contribute to the development of AKI, and intraoperative use of noradrenaline serves as a protective factor. The predictive model could potentially facilitate early prediction and surveillance of AKI. (Hepatobilinty Pancreat Dis Int 2010; 9:259-263)展开更多

The incidence of HA thrombosis has been reduced by the introduction of nucrosurgical techniques under a high resolution microscope or loupe. METHODS: We report our experience in 101 cases of HA reconstruction in LDLTs using the graft-artery-undamp and posterior-wall-first technique. The reconstructions were completed by either a plastic surgeon or a transplant surgeon. RESULTS: The rate of HA thrombosis was 2% (2/101). The risk factors for failed procedures appeared to be reduced by participation of the transplant surgeon compared with the plastic surgeon. For a graft with duplicate arteries, we considered no branches should be discarded even with a positive clamping test. CONCLUSIONS: HA reconstruction without clamping the graft artery is a feasible and simplified technique, which can be mastered by transplant surgeons with considerable microsurgical training.展开更多

Many previous studies have demonstrated controversial results of the application of steatotic liver grafts. The aim of the present study was to summarize our experience and evaluate the value of steatotic liver grafts. METHODS: The clinical and follow-up data of 24 adult patients receiving moderately steatotic liver grafts (30%-60%) from May 2003 to June 2005 (group 1) were analyzed. After matching for age, gender, model for end-stage liver diseases score and cold ischemia time, another 24 patients receiving liver grafts with steatosis less than 30% were chosen as the control group (group 2). The patient and graft outcomes were compared between the two groups. RESULTS: No difference of liver and kidney functions in the first post-transplant week was found between the two groups (P > 0.05). Neither the incidence of early allograft dysfunction and acute kidney injury nor the patient survival rates (3 months, 6 months and 1 year) showed differences between groups 1 and 2 (P > 0.05). CONCLUSION: Moderately steatotic liver grafts provide adequate function in the first phase after transplantation and can be used for transplantation.展开更多

A -160 C -> A polymorphism in the promoter region of E-cadherin has been reported to decrease gene transcription. This allelic variation may be a potential genetic marker for identifying those individuals at higher risk for invasive/metastatic disease. METHODS: The effect of E-cadherin gene polymorphism on risk of tumor recurrence was studied in 93 patients with hepatocellular carcinoma (HCC) after liver transplantation, and determined whether this polymorphism is a biomarker for the risk of tumor recurrence. RESULTS: The genotype frequencies in the patients with recurrence were C/C: 0.667, C/A: 0.311, and A/A: 0.022, and in-the patients without recurrence C/C: 0.604, C/A: 0.271 and A/A: 0.125. No significant difference was found between the two groups (P = 0.171). Between -160 C -> A polymorphism and the clinicopathological data, there were no statistically significant differences in the distribution of the parameters as to age, gender, portal vein tumor thrombi, preoperative alpha-fetoprotein level, tumor size, or histopathological grading (P > 0.05). CONCLUSION: The results of this study show no association exists between the E-cadherin genotype and the risk of tumor recurrence in Chinese patients with HCC.展开更多

Recurrence of HBV is one of the frequent complications. In the present study, we investigated whether human leukocyte antigen (HLA) matching influences the incidence of HBV recurrence, and the time point of HBV recurrence after LT. METHODS: One hundred and two recipients of LT with end-stage chronic HBV infection were reviewed. The triple-drug immunosuppression regimen consisted of tacrolimus, mycophenolate, and prednisone. All patients were subjected to prophylaxis with hepatitis B immunoglobulin and lamivudine. HLA typing was performed using a sequence-specific primer-polymerase chain reaction kit. Serology for hepatitis B and HBV DNA was examined using a commercial kit. RESULTS: The incidence of recurrent HBV infection post-LT was 6.86%. The recurrent infection of HBV was independent of the degree of H LA matching (P>0.05). The time point of HBV recurrence, however, was prolonged in HLA-A matched patients compared with matchless patients (P=0.049). The recurrence of HBV infection was independent of H LA compatibility. CONCLUSIONS: This retrospective analysis showed that more HLA-A locus compatibility is associated with a prolonged time of recurrence of HBV in patients after LT for end-stage HBV infection. The incidence of HBV recurrence is independent of HLA compatibility. (Hepatobiliary Pancreat Dis Int 2010; 9: 139-143)展开更多

Essentially, abnormalities in all known enzymes involved in the synthesis or degradation of glycogen and glucose have been found to cause some type of GSD. Liver and muscle have abundant quantities of glycogen and are the most common and seriously affected tissues. This study was to assess reduced-size liver transplantation for the treatment of GSD. METHODS: The clinical data from one case of GSD type I with hepatic adenoma was retrospectively analyzed. The clinical manifestations were hepatomegaly, delayed puberty, growth retardation, sexual immaturity, hypoglycemia, and lactic acidosis, which made the young female patient eligible for reduced-size liver transplantation. RESULTS: The patient recovered uneventfully with satisfactory outcome, including 12 cm growth in height and 5 kg increase in weight during 16 months after successful reduced-size liver transplantation. She has been living a normal life for 4 years so far. CONCLUSIONS: Reduced-size liver transplantation is an effective treatment for GSD with hepatomegaly and hepatic adenoma. Delayed puberty, growth retardation, hypoglycemia and lactic acidosis can be cured by surgery.展开更多

This article mainly describes our experience in managing a patient with celiac artery stenosis and HAT after liver transplantation. METHODS: A 44-year-old man with a 15-year history of hepatitis B was admitted to our hospital for hepatocellular carcinoma. Before the operatiori, he received transarterial chemoembolization once, and pretransplant MR angiography indicated a suspected stenosis at the initiation of the celiac artery, while color Doppler showed normal blood flow in the arterial system. In this case, orthotopic liver transplantation was performed for radical cure of hepatocellular carcinoma. However, B-ultrasonography detected poor blood flow in the intra- and extra-hepatic artery on the first posttransplant day, and during exploratory laparotomy a thrombus was found in the hepatic artery. Thus, re-transplantation was conducted with a bypass between the graft hepatic artery and the recipient abdominal aorta with the donor's splenic artery. RESULTS: The patient made an uneventful recovery and color Doppler showed good blood flow in the artery and portal system. Histology confirmed extensive thrombosis in the left and right hepatic artery of the explanted graft, indicating HAT. CONCLUSIONS: Although HAT caused by celiac trunk compression is rarely reported in liver transplantation, the diagnosis should be considered in patients with pretransplant hepatic artery stenosis on angiography and abnormal blood flow on B-ultrasonography. Once HAT is formed, treatment such as thrombectomy or retransplantation should be performed as early as possible.展开更多
