Ex vivo liver resection and autotransplantation as alternative to allotransplantation for end-stage hepatic alveolar echinococcosis.

BACKGROUND & AIMS: Radical resection is the best treatment for patients with advanced hepatic alveolar echinococcosis (AE). Liver transplantation is considered for selected advanced cases; however, a shortage of organ donors and the risk of postoperative recurrence are major challenges. The aim of this study was to assess the clinical outcomes of ex vivo liver resection and autotransplantation for end-stage AE. METHODS: In this prospective study, 69 consecutive patients with end-stage hepatic AE were treated with ex vivo resection and liver autotransplantation between January 2010 and February 2017. The feasibility, safety and long-term clinical outcome of this technique were assessed. RESULTS: Ex vivo extended hepatectomy with autotransplantation was successful in all patients without intraoperative mortality. The median weight of the graft and AE lesion were 850 (370-1,600) g and 1,650 (375-5,000) g, respectively. The median duration of the operation and anhepatic phase were 15.9 (8-24) h and 360 (104-879) min, respectively. Six patients did not need any blood transfusion. Complications higher than IIIa according to Clavien classification were observed in 10 patients. The 30-day-mortality and overall mortality (>90 days) were 7.24% (5/69) and 11.5% (8/69), respectively. The mean hospital stay was 34.5 (12-128) days. Patients were followed-up systematically for a median of 22.5 months (14-89) without recurrence. CONCLUSION: This is the largest series assessing ex vivo liver resection and autotransplantation in end-stage hepatic AE. This technique could be an effective alternative to liver transplantation in patients with end-stage hepatic AE, with the advantage that it does not require an organ nor immunosuppressive agents. LAY SUMMARY: Ex vivo liver resection and autotransplantation were performed in a large series of patients with end-stage hepatic alveolar echinococcosis. The results showed that this surgical option was feasible, with acceptable postoperative mortality, but 100% disease-free survival in survivors. Careful patient selection, as well as precise assessment for size and quality of the remnant liver are key to successful surgery.

Acidic extracellular microenvironment promotes the invasion and cathepsin B secretion of PC-3 cells.

BACKGROUND: This study aimed to investigate the effect of acidic microenvironment on the invasion of prostatic carcinoma PC-3 cells and to explore the potential mechanism. MATERIAL AND METHODS: PC-3 cells were maintained in medium at different pHs (pH 7.4, pH 7.0 and pH 6.6). Invasion and metastasis of PC-3 cells were investigated in vitro. Acridine orange staining was performed, followed by laser confocal scanning microscopy for the localization of lysosomes. Western blot assay and ELISA were employed to evaluate the effect of acidic microenvironment on the cathepsin B secretion. RESULTS: Acidic microenvironment remarkably promote the invasion and migration of PC-3 cells (P<0.01). Moreover, at acidic extracellular pH (pHe), an obvious shift of lysosomes from the perinuclear region to the periphery was observed. Western blot assay and ELISA revealed that acidic microenvironment promoted the cathepsin B secretion in PC- cells. CONCLUSION: Acidic microenvironment may significantly promote the invasion of PC-3 cells and increase the secretion of cathepsin B. This suggests that the acidic microenvironment induced invasion of PC- cells is related to the elevated cathepsin B secretion.

GSTP1 arrests bladder cancer T24 cells in G0/G1 phase and up-regulates p21 expression.

OBJECTIVE: GSTP1 over-expression was introduced into human bladder cancer T24 cells via the lentivirus system. The influence of GSTP1 on the proliferation and cell cycle of T24 cells as well as the potential mechanisms was investigated. METHODS: The lentiviral vector GSTP1-pWPXL was constructed and transfected into T24 cells in the presence of Lipofectamine 2000. CCK8 assay and colony formation test were performed to explore the impact of GSTP1 on the proliferation of T24 cells. Ollowing PI staining, flow cytometry was done to detect the proportion of T24 cells in different phases. Western blot assay was conducted to detect the protein p21 expression. RESULTS: When compared with control group, T24 cells with GSTP1 over-expression showed significant reduction in cell proliferation (P < 0.01) and they were arrested in G0/G1 phase. Western blot assay indicated that the p21 protein expression in T24 cells with GSTP1 over-expression was significantly higher than that in control group. CONCLUSION: GSTP1 may inhibit the proliferation of T24 cells and arrest these cells in G0/G1 phase, which may be ascribed to the up-regulated expression of p21.

LncRNAs expression signatures of hepatocellular carcinoma revealed by microarray.

AIM: To analyze the expression profiles of long non-coding RNAs (lncRNAs) in hepatocellular carcinoma. METHODS: Hepatocellular carcinoma (HCC) tissues and matched adjacent non-tumor (NT) liver tissues were collected from 29 patients with HCC, immediately after liver resection, between March 2011 and July 2013. The diagnosis of HCC was made based on histological examination. Differentially expressed lncRNAs between HCC and NT tissues were revealed through microarray-based lncRNAs expression profiling. Further, quantification of selected lncRNAs was performed using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). RESULTS: Six hundred and fifty-nine lncRNAs were differentially expressed between HCC and NT tissues, of which five [TCONS_00018278, AK093543, D16366, ENST00000501583, NR_002819 (MALAT1)] were selected for validation. Four of them were significantly downregulated in HCC tissues compared with NT tissues (P = 0.012, 0.045, 0.000 and 0.000, respectively), and the expression level of MALAT1 showed no significant difference (P = 0.114). CONCLUSION: This study identified a set of lncRNAs differentially expressed in HCC tissues and provided useful information for exploring potential therapeutic targets and diagnostic biomarkers of this cancer.

Supine lithotomy versus prone position in minimally invasive percutaneous nephrolithotomy for upper urinary tract calculi.

OBJECTIVE: To compare operative time, safety and effectiveness of minimally invasive percutaneous nephrolithotomy (MPCNL) in the supine lithotomy versus prone position. METHODS: Between January 2008 and December 2010, a total of 109 consecutive patients with upper urinary tract calculi were enrolled and randomly divided into group A (53 patients, supine lithotomy position) and group B (56 patients, prone position). The MPCNL procedures were performed under the guidance of real-time grayscale ultrasound system. The preoperative characteristics, intraoperative and postoperative parameters were analyzed and compared. RESULTS: All patients were successfully operated. There was no significant difference between the two groups in stone-free rate (group A 90.1 vs. group B 87.5%, p = 0.45), mean blood loss, number of access tracts, calyx puncture, mean hospital stay (group A 6 ± 1.1 vs. group B 6 ± 1.5 days, p = 0.38) and complications. But the operative time was significantly shortened in supine lithotomy position (group A 56 ± 15 vs. group B 86 ± 23 min, p < 0.001). CONCLUSIONS: The effectiveness and safety of the supine lithotomy position for MPCNL were similar to the prone position. However, the supine lithotomy position has an important advantage of reducing the operative time. The supine lithotomy position could be a good choice to perform MPCNL.

[Efficacy and safety of sorafenib in the prevention and treatment of hepatocellular carcinoma recurrences after liver transplantation].

OBJECTIVE: To evaluate the efficacy and safety of sorafenib in the prevention and treatment of hepatocellular carcinoma (HCC) relapse after liver transplantation. METHODS: A retrospective cohort study was performed to assess the efficacy and safety of sorafenib for HCC. Forty-four patients who underwent liver transplant for HCC beyond Milan criteria form July 2007 to May 2010 were included study group (sorafenib, n = 22) and control group (without sorafenib, n = 22). The primary endpoints of the study were disease-free survival (DFS), overall survival (OS). Secondary outcomes included the rates of acute rejection and graft survival. RESULTS: The clinical data of 44 patients were completely collected. There were significantly differences between sorafenib group and control group in 1-year DFS (81.8% (n = 18) vs 63.6% (n = 14), P < 0.05) and OS (90.9% (n = 20) vs 72.7% (n = 16), P < 0.05) respectively. The acute rejection rates in Sorafenib were 13.6% (3/22), compared with 18.2% (4/22) in control group (P = 0.524) and 1-year graft survival in Sorafenib group were 86.4% (19/22), compared with 72.7% (16/22) in control group (P = 0.086). The overall incidence of treatment-related adverse events was 68.1% (n = 15) in sorafenib group and 31.8% (n = 7) in the control group (P < 0.01). Adverse events that were reported for patients receiving sorafenib were predominantly grade 1 or 2 in severity including diarrhea (45.5%, n = 10), liver dysfunction (40.9%, n = 9), hand-foot skin reaction (31.8%, n = 7) and pains of head and four limbs (22.7%, n = 5). Two patients with grade 3 adverse events in study group were stopped continuing to use the sorafenib. Three patients with the dose of 400 mg twice daily and 17 patients with the dose reduction of sorafenib continued to the study endpoint. CONCLUSION: Patients with HCC undergoing liver transplantation could get the benefits of Sorafenib in reducing the incidence of tumor recurrence and extending disease-free and overall survival time.

[Clinical characteristics, diagnosis and treatment of digestive tract leakage after orthotopic liver transplantation].

OBJECTIVE: To investigate the clinical characteristics, diagnosis and treatment of digestive tract leakage after orthotopic liver transplantation (OLT). METHODS: Sixty-one recipients had digestive tract leakage in early stage after OLT among 1173 cases from January 2000 to December 2010. There were 55 male and 6 female patients, aging from 36 to 61 years, with a median of 45 years. Digestive tract leakage included bile leakage (46 cases), gastric leakage (5 cases), duodenal leakage (1 case), jejunal leakage (4 cases), ileal leakage (1 case) and colon transversum leakage (4 cases). Ten of recipients with gastrointestinal leakage had 1 to 3 times of abdominal surgery before OLT. Abdominal drainage was used in 28 cases with bile leakage, and additionally, endoscopic retrograde cholangiopancreatography, endoscopic nasobiliary drainage and stenting were performed for 8 of them, and surgical neoplasty for another 18 patients with bile leakage. Simple surgical neoplasty of perforation was performed for 13 patients with gastrointestinal leakage, and diverticulectomy and neoplasty for 1 case with duodenal leakage, and partial jejunostomy for one severe jejunal leakage. Nutritional support was administered for all of cases. RESULTS: The incidence rate of digestive tract leakage in early stage after OLT was 5.20% (61/1173). Intra-operative iatrogenic injury of gastrointestinal tract was occurred in 6 cases with gastrointestinal leakage. After treatment, 11 cases died of multiple organ failure resulted from severe infection, with mortality of 18.0% (11/61), including 4 cases with bile leakage, with the mortality of 8.6% (4/46), and 7 cases with gastrointestinal tract leakage, with the mortality of 46.6% (7/15). The remanent 50 cases through comprehensive treatment with a span of 1 to 3 months recovered and discharged healthily. No digestive tract leakage reoccurred in the follow-up of 6 to 84 months. CONCLUSIONS: The morbidity of digestive tract leakage in early stage after OLT is low, but its mortality is high, especially for gastrointestinal tract leakage. High dose corticosteroids therapy, history of abdominal operation and intra-operative iatrogenic injury may be high risk factor. Comprehensive treatment is crucial for improving prognosis.

[A study of the efficacy and safety of using hepatitis B surface antigen-positive donors for liver transplantation].

OBJECTIVE: To evaluate the outcomes of liver transplant recipients who received liver allografts from hepatitis B surface antigen (HBsAg)-positive donors. METHODS: The medical records of 23 male patients (median age, 42.5 years; range: 29-61) who received HBsAg-(+) liver allografts in our organ transplant center were retrospectively analyzed. All patients had confirmed diagnosis of end-stage liver disease (ESLD) secondary to hepatitis B virus (HBV) infection, including 13 HBsAg(+)/HBeAg(-)/HBcAb(+) cases and 10 HBsAg(+)/HBeAb(+)/HBcAb(+) cases. After transplantation, all patients were administered oral entecavir and intravenous anti-hepatitis B immunoglobulin (HBIG) (2000 IU/d during the first week), along with a steroid-free immune suppression regimen. HBV-related antigen and antibody and HBV DNA were detected on post-transplantation days 1, 7, 14, 21, and 30. The liver allografts were monitored by ultrasound imaging. After discharge, monthly follow-up recorded liver function, renal function, acute rejection, infections, vascular complications, biliary complications, HBV recurrence, cancer recurrence, and patient survival. RESULTS: Two of the recipients died from severe perioperative pneumonia. The remaining 21 recipients were followed-up for 10 to 38 months, and all 21 patients remained HBsAg(+). One recipient developed biliary ischemia and required a second liver transplantation at five months after the primary transplantation. Three recipients (all primary) died from tumor recurrence at 9, 14, and 18 months post-transplantation, respectively. All other recipients survived and had acceptably low HBV DNA copy levels. Color Doppler imaging showed good graft function and normal texture. The patient and graft survival rates were 78.3% (18/23) and 73.9% (17/23), respectively. The recurrence rate of HBV infection was 100% (23/23). In surviving patients, no liver function abnormality, graft loss, or death was found to be related to the recurrence of HBV infection. CONCLUSION: Liver transplantation using HBsAg(+) liver grafts was safe for patients with ESLD secondary to HBV infection.

Surgical resection plus biotherapy/chemotherapy improves survival of hepatic metastatic melanoma.

AIM: To analyze the correlation of treatment method with the outcome of all the hepatic metastatic melanoma (HMM) patients from our hospital. METHODS: There were altogether nine cases of HMM that had been treated in the PUMCH hospital during the past 25 years, from December 1984 to February 2010. All of the cases developed hepatic metastasis from primary cutaneous melanoma. A retrospective review was performed on all the cases in order to draw informative conclusion on diagnosis and treatment in correlation with the prognosis. Clinical features including symptoms, signs, blood test results, B-ultrasound and computed tomography (CT) imaging characteristics, and pathological data were analyzed in each case individually. A simple comparison was made on case by case basis instead of performing statistical analysis since the case numbers are low and patients were much diversified in each item that has been analyzed. Literatures on this subject were reviewed in order to draw a safe conclusion and found to be supportive to our finding in a much broad scope. RESULTS: There are six males and three females whose ages ranged 39-74 years old with an average of 58.8. Patients were either with or without symptoms at the time of diagnosis. The liver function and tumor marker exam were normal in all but one patient. The incidence of HMM does not affect liver function and was not related to virus infection status in the liver. Most of these HMM patients were also accompanied by the metastases of other locations, including lung, abdominal cavity, and cervical lymph nodes. Ultrasound examinations showed lesions ranging 2-12 cm in diameter, with no- or low-echo peripheral areola. Doppler showed blood flow appeared inside some tumors as well as in the surrounding area. CT image demonstrated low density without uniformed lesions, characterized with calcification in periphery, and enhanced in the arterial phase. Contrast phase showed heterogeneous enhancement, with a density higher than normal liver tissue, which was especially apparent at the edge. Patients were treated differently with following procedures: patients #1, #6 and #8 were operated with hepatectomy with or without removal of primary lesion, and followed by comprehensive biotherapy/chemotherapy; patient #9 received hepatectomy only; patient #2 received bacille calmette-guerin treatment only; patient #7 had Mile's surgery but no hepatectomy; and patients #3, #4 and #5 had supportive treatment without specific measurement. The patients who had resections of metastatic lesions followed by post-operative comprehensive therapy have an average survival time of 30.7 mo, which is much longer than those did not receive surgery treatment (4.6 mo). Even for the patient receiving a resection of HMM only, the post-operative survival time was 18 mo at the time we reviewed the data. This patient and the patient #6 are still alive currently and subjected to continue following up. CONCLUSION: Surgical operation should be first choice for HMM treatment, and together with biotherapy/chemotherapy, hepatectomy is likely to bring better prognosis.

[Diagnosis and treatment of primary hepatic angiosarcoma: a report of 7 cases with a literature review].

OBJECTIVE: To explore the clinical features, diagnosis, treatment and prognosis of primary hepatic angiosarcoma (PHA). METHODS: The clinical data of 7 PHA patients admitted to our hospital from December 2004 to December 2010 were retrospectively analyzed and the relevant literatures reviewed. RESULTS: Seven cases (5 males and 2 females) were diagnosed as PHA among 1027 (0.68%) patients with primary hepatic malignant tumors. Their mean age was 43.3 years old (range: 33 - 74). Four cases were of solitary lesion and three of multiple lesions. No specific clinical features were observed. The PHA lesions were easily misdiagnosed as benign or hepatic metastatic tumors. Contrast enhanced ultrasound (CEUS) showed the lesions with characteristic manifestations. And the positron emission tomography (PET-CT) could confirm the hepatic lesions as malignant tumors. The survival time for two untreated cases was 3 & 5 months, for two cases with liver transplantation (LTx) 3 & 8 months and for two cases treated with surgical resection & targeted therapy was 14 & 19 months respectively. One case was lost to follow-up at 6 months after hepatic resection. CONCLUSION: PHA is a clinically rare and highly malignant tumor with a rapid progression and a poor prognosis. Both CEUS and PET-CT are helpful for its differential and confirmative diagnosis. LTx should be considered as a contraindication for PHA. Hepatic resection has proven to be beneficial for PHA patients with solitary lesion. Surgical resection plus targeted medicines may improve their survival.

[Effect of Campath-1H induction on immunosuppression in small intestine transplantation].

OBJECTIVE: To investigate the effect of Campath-1H induction on immunosuppression in small intestine transplantation. METHODS: Clinical data of a patient who underwent small intestine transplantation were retrospectively summarized. RESULTS: Intraoperative Campath-1H induction by intravenous injection was administered. Triple immunosuppression(FK506, MMF and methylprednisolone) was used postoperatively. The lymphocyte and leukocyte decreased significantly following Campath-1H induction, and returned to normal after adjusting the dose of immunosuppressant and use of colony stimulating factor. There were no acute rejection, graft versus host disease, or severe infection during the immediate postoperative period. The patient recovered and discharged. CONCLUSION: Intraoperative Campath-1H induction and postoperative triple immunosuppression using FK506, MMF, and methylprednisolone may prevent rejection and graft versus host disease in the early stage after small intestine transplantation.

[Application of steroids minimization immunosuppressive regimen in liver transplantation].

OBJECTIVE: To investigate the safety and feasibility of steroids minimization immunosuppressive regimen in liver transplantation. METHODS: One hundred and sixteen patients in line with the selecting criteria from January 2005 to June 2008 were divided into three groups according to the withdrawal of steroids: 40 cases in 3 months withdrawal group, 40 cases in 7 d withdrawal group and the other 36 cases in 24 h withdrawal group. The difference of recipients' survival, infection, acute rejection and steroids resistant acute rejection, wound healing, recurrence of HBV and hepatocellular cell (HCC), new on-set of diabetes, hyperlipidemia and hypertension between the three groups were compared. RESULTS: The difference of recipients' survival, acute rejection including steroids resistant acute rejection, recurrence of HBV and HCC, hyperlipidemia between the three groups were not significant (P > 0.05), the incidence of wound un-healing and hypertension in 24 h withdrawal group was significantly lower than that in the other 2 groups (P < 0.05), the incidence of infection and new on-set diabetes in 24 h withdrawal group and 7 d withdrawal group was significantly lower than that in 3 months withdrawal group (P < 0.05). CONCLUSION: Steroids minimization immunosuppressive strategy is safe and feasible in liver transplantation field, it will significantly reduce the steroids related complications without increasing the risk of rejection.

Postoperative adjuvant antiviral therapy for hepatitis B/C virus-related hepatocellular carcinoma: a meta-analysis.

AIM: To investigate the impact of postoperative antiviral treatment on tumor recurrence and survival of patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection-related primary hepatocellular carcinoma (HCC) after curative therapy. METHODS: We performed a meta-analysis of randomized and non-randomized control trials from electronic search and manual search. The fixed effect model of Mantel-Haenszel method and the random effect model of Der Simonian and Laird method were used for homogeneous and heterogeneous studies, respectively. Seven HCV-related studies, three HBV-related studies and three studies on HBV or HCV-related HCC were identified. RESULTS: A total of 1224 patients were included in this analysis. The estimated odds ratios (OR) for the 1-, 2-, 3- and 5-year recurrence were 0.54 [15.4% vs 24.1%, 95% confidence interval (CI): 0.32-0.89, P = 0.02], 0.42 (36.9% vs 58.0%, 95% CI: 0.19-0.90, P = 0.03), 0.37 (47.9% vs 63.8%, 95% CI: 0.19-0.71, P = 0.003), and 0.32 (66.7% vs 74.3%, 95% CI: 0.15-0.66, P = 0.002), respectively; and the OR for the 1-, 2-, 3-, 5- and 7-year mortality were 0.23 (1.2% vs 9.1%, 95% CI: 0.07-0.71, P = 0.01), 0.31 (6.4% vs 22.1%, 95% CI: 0.12-0.79, P = 0.01), 0.43 (12.7% vs 20.8%, 95% CI: 0.21-0.89, P = 0.02), 0.42 (25.1% vs 42.0%, 95% CI: 0.27-0.66, P = 0.0002) and 0.28 (31.9% vs 52.2%, 95% CI: 0.13-0.59, P = 0.0008). CONCLUSION: This meta-analysis indicates the postoperative antiviral therapy, interferon in particular, may serve as a favorable alternative to reduce recurrence and mortality in patients with HBV/HCV related HCCs.

[A survival analysis of patients with early-stage hepatocellular carcinoma fulfilling Milan criteria and undergoing hepatectomy].

OBJECTIVE: To summarize the experience of hepatectomy in patients with hepatocellular carcinoma fulfilling the Milan criteria and analyze the clinicopathological factors for patient survival and tumor recurrence. METHODS: The clinicopathological data of 104 patients with early-stage hepatocellular carcinoma fulfilling the Milan criteria and underwent hepatectomy at Peking Union Medical College Hospital between April 2003 and June 2009 were retrospectively analyzed. RESULTS: The median follow-up was 24 months. There were 54 recurrent cases. The 1-, 3- and 5-year cumulative disease-free survival rate were 63.0%, 32.6% and 22.4% respectively. Neither univariate analysis nor multivariate analysis indicated any factor significantly correlated with recurrence (P>0.05). The cumulative overall survival rate at 1, 3 and 5 years were 88.8%, 68.1% and 68.1% respectively. Univariate analysis revealed that blood transfusion (P=0.000), involvement of hepatic capsule (P=0.000) and postoperative transarterial chemotherapy (P=0.049) were significantly correlated with survival. And multivariate analysis indicated that blood transfusion (P=0.001) and involvement of hepatic capsule (P=0.000) were independent prognostic factors for survival. CONCLUSION: For the patients with early-stage hepatocellular carcinoma and compensated liver function fulfilling the Milan criteria, hepatectomy serves as the preferred treatment strategy.

Tolerogenic semimature dendritic cells induce effector T-cell hyporesponsiveness by the activation of antigen-specific CD4+ CD25+ T-regulatory cells.

OBJECTIVES: Researchers recently discovered a group of semimature dendritic cells that induce autoimmune tolerance by activating host antigen-specific CD4+CD25+ T-regulatory cells. We hypothesized that donor semimature dendritic cells injected into recipients would induce effector T-cell hyporesponsiveness by activating CD4+CD25+ T-regulatory cells. MATERIALS AND METHODS: Donor myeloid semimature dendritic cells were cultivated for 6 days and were then stimulated with tumor necrosis factor a for 24 hours. BALB/c mice were pretreated with semimature dendritic cells to generate antigen-specific CD4+CD25+ T-regulatory cells in vivo. The role of CD4+CD25+ T-regulatory cells in transplant immunity was studied via mixed lymphocyte culture in vitro. RESULTS: Surface markers and cytokines secreted by semimature dendritic cells differed from those secreted by immature myeloid dendritic cells or mature dendritic cells. Semimature dendritic cells and immature myeloid dendritic cells did not activate allogenic lymphocyte responses in coculture studies. CD4+CD25+ T-regulatory cells of recipients challenged by donor semimature dendritic cells, which expressed a high level of interleukin-10, induced hyporesponsiveness in host effector T cells that were stimulated by donor splenocytes. In contrast, CD4+CD25+ T-regulatory cells did not induce hyporesponsiveness in effector T cells when the host T cells were stimulated by third-party antigen from DBA2 mice splenocytes. CONCLUSIONS: Our findings confirm that semimature dendritic cells are an independent subgroup of dendritic cells in both immune function and morphologic profile. It may be the cytokine secretion profile of semimature dendritic cells (rather than that of surface markers) that has a key role in inducing CD4+CD25+ T-regulatory cells to express a high level of interleukin-10. Immunization with donor semimature dendritic cells may be an effective method of inducing transplant tolerance, but further evidencebased studies of that topic are necessary.

[Two-dose steroid combined with two-dose daclizumab and tacrolimus regimen in liver transplant recipients].

OBJECTIVE: To investigate the efficiency and safety of two-dose steroid combined with two-dose daclizumab and tacrolimus (FK506) regimen in liver transplant recipients. METHODS: There were 74 patients who treated in the First Affiliated Hospital of Sun Yat-Sen University from September 2006 to March 2008. Expect for 7 patients who didn't measure up, 67 adult liver transplant recipients were randomized into two groups: conventional protocol group (n = 35) in which steroid was withdrawn in 3 months after operation, and two-dose steroid group (n = 32). Comparison of rejection, infection (bacteria, fungal and cytomegalovirus) and metabolic complications rates were studied between two groups. RESULTS: There were significant differences between two groups in the rate of early postoperation hyperglycemia, the average dosage of insulin consumption among hyperglycemia recipients as well as the rate of diabetes mellitus, hypertension and infection during the follow-up period (P < 0.05). The rate of hypertension in early postoperation period, hyperlipemia and rejection rate during the follow-up period were similar in two groups (P > 0.05). CONCLUSIONS: Two-dose steroid combined with two-dose daclizumab and tacrolimus would be a safe and efficient immunosuppression strategy without increase the acute rejection rate hazard, that could reduce post-transplant infection and other complications from side-effect of long-term usage of steroid.
