Objective:To explore the feasibility of withdrawing immunosuppression after pediatric liver transplantation (LT) and to explore the related influencing factors of immune tolerance.Methods:Clinical data were retrospectively reviewed for 14 children undergoing LT and withdrawing immunosuppressant postoperatively from January 2013 to January 2017. There were 8 boys and 6 girls with a body mass index (BMI) of (20.32±4.65) kg/m 2. The age of recipients at the time of transplantation ranged from 0.58 to 0.71 years and the median age was 0.58 years. The recruiting age ranged from 2.65 to 4.52 years and the median age was 3.75 years. And the interval from transplantation to inclusion was (3.08±1.10) years. Among donors, there were 6 males and 8 females with an age range of (22.84±13.93) years. In 14 cases, liver transplant was performed for patients with biliary atresia, including living donor liver transplantation (n=10) and cadaveric liver transplantation (n= 4) . Among participants in immunosuppressant withdrawing, 4 cases had immunosuppressant removed for post transplant lymphoproliferative disorder (PTLD) . All of them received immunotherapy post-LT. Children aged >6 years received a triple regimen of steroid + tacrolimus (FK506) + montecoculphate while those aged ≤6 years had a double regimen of hormone + FK506. In 10 cases, immunosuppressant was withdrawn according to the withdrawal plan. Four PTLD children received immunosuppressive tapering alone according to pathological type and clinical symptoms. Periodic liver function tests and programmed liver biopsies were performed at the beginning of the study, 1 year and 2 years. Hematoxylin eosin (HE) staining was performed for evaluating acute liver rejection and fibrosis by Banff standard and Ishak scoring system. Results:Among them, 5/14 children successfully stopped immunosuppressive to achieve immune tolerance. Nine children became immune intolerant and 3 had normal liver function during follow-ups. However, the pathological results of programmed liver biopsy hinted at rejection. The remaining 6 cases showed abnormal liver function during follow-ups and liver function normalized after resuming immunosuppressive therapy. As compared with immune intolerants, age at the time of transplantation was smaller for immune tolerants. The median age of transplantation was 0.58 (0.50~0.58) years. The age of immune intolerants during transplantation was 0.67 (0.58~ 2.04) years and the difference was statistically significant ( P=0.012, Z= -2.51 ) . The level of direct bilirubin (DBIL) in immune tolerants was lower than that in immune intolerants. The median value of DBIL was 2.47(2.23~2.53) μmol/L in immune tolerants and 2.63(2.52~2.99) μmol/L in immune intolerants and the difference was statistically significant ( P=0.004, Z= -2.87) . Conclusions:The proportion of immune tolerance after pediatric liver transplantation remains high and age and DBIL level affect immune tolerance.
Objective:To evaluate the efficacy of basiliximab plus single steroid induced immunotherapy during donor-recipient ABO-compatible pediatric liver transplantation(LT).Methods:From January 1, 2019 to January 19, 2020, a total of 150 children of donor-recipient ABO-compatible LT were randomly divided into basiliximab group(basiliximab plus single steroid induction and postoperative immunosuppression with tacrolimus alone)and steroid group(conventional dose of steroid induction plus postoperative immunosuppression with tacrolimus and steroid). Clinical characteristics, survival rate of recipients and liver allografts, rejection rate and infection rate were observed.Results:The median follow-up time was 9.2(0.7~15.5)months.No significant inter-group differences existed in survival rate of recipients/grafts or the incidence of acute rejection, early postoperative pulmonary infection, cytomegalovirus and Epstein Barr virus infection. However, in 56 living donor LT, acute rejection(6cases, 10.7%)occurred in basiliximab group versus(12cases, 25.5%)in steroid group. During living donor LT, the incidence of acute rejection declined markedly in bsiliximab group as compared with steroid group( P=0.043). Conclusions:Both safe and effective for donor-recipient ABO-compatible pediatric LT, basiliximab plus single steroid induced immunotherapy can significantly lower the occurrences of acute rejection during living donor LT.

Objective To detect the protective effect of extracorporeal membrane oxygenation (ECMO) on Maastricht type Ⅱ donation after cardiac death (DCD) liver transplantation in pigs.Methods Twenty mini-pigs were randomized into ECMO group (n =10) and control group (n =10).Then 10 pigs in each group were randomized into donors and recipients.Maastricht type Ⅱ DCD model was induced in all of the 10 donors.Donors of ECMO group received 2-h ECMO after cardiac death,then underwent liver graft procurement.The donors of control group underwent liver procurement directly after cardiac death.Recipients of two groups underwent orthotopic liver transplantation without venovenous bypass.During this procedure,vital signs were monitored continuously,lactate and liver biochemistry were tested,and 5-day survival rate was observed.Results Maastricht type Ⅱ DCD model was successfully built in all of the donors with consequent dark liver.For donors of ECMO group,liver turned sanguinous and soft quickly after treatment of ECMO.There were no significant differences in operation time,anhepatic time and anhepatic hemodynamic changes between these two groups (P > 0.05).As compared with control group,ECMO group had better hemodynamic parameters 30 min after reperfusion,lower lactate,ALT and AST levels 30 min after reperfusion and before closing the abdomen,and higher 5-day survival rate (P < 0.05).Conclusion ECMO may improve the quality of Maastricht type Ⅱ DCD liver graft,and increase the survival rate of DCD liver transplantation.
OBJECTIVE:To determine the effective dose of hepatitis B immunoglobulin (HBIG) for clearing maternally-transmitted hepatitis B virus (HBV) from a newborn.METHODS:Full-term neonates born to HBV-infected mothers were tested for hepatitis B surface antigen (HBsAg) and HBV DNA in venous blood, Individuals with positive results within two hours after birth were selected for study, and divided among two treatment groups: research group receiving HBIG continually adjusted to quantitative levels of neonatal HBsAg and HBV DNA levels; control group receiving standard HBIG 200IU dose. All neonates were also treated with 10 micrograms of recombinant vaccine. The decreases in HBsAg and HBV DNA over 12 months were comparatively analyzed between the two treatment groups.RESULTS:The two treatment groups (HBIG adjusted vs. standard) were statistically similar in Apgar score (9.38+/-0.49 vs. 9.37+/-0.48), neonate body weight (3458.67+/-374.93 vs. 3558.61+/-322.85 g), maternal age (26.33+/-3.63 vs. 25.33+/-3.03), and initial HBsAg and HBV DNA levels (rank sum test Z = 1.381, and Z = 0.700, respectively) (all, P more than 0.05). Successful clearance of HBV infection within 12 months was achieved in significantly more neonates in the HBIG adjusted therapy group than in the standard therapy group (82.8% vs. 57.4%; x2 = 9.696, P less than 0.05).CONCLUSION:Adjusting the neonatal HBIG dose according to HBsAg and HBV DNA levels can improve the success rate of clearing maternally-transmitted HBV.

Objective To observe the HBsAg neutralization capability of hepatitis B immune globulin(HBIG) in vitro test and in vivo among newborn infants.Methods A group of 63 infants born to HBsAg-positive mothers were successfully immunized with HBV vaccine and HBIG.Forty-three of the infants had serum HBsAg less than or equal to 40 ng/ml(group Ⅰ) and 17 of the cases had serum HBsAg greater than 40 ng/ml(group Ⅱ).The concentration of anti-HBs was evaluated on day 4-7 after the application of 200 IU HBIG.The HBsAg neutralization capability of HBIG in vivo was compared the capability in vitro.Results The average amount of anti-HBs was 226.4 IU in newborn infants on day 4-7 after the application and HBIG and HBV vaccine.One IU HBIG neutralized 42 ng HBsAg in vitro,while 1 IU neutralized only 2.04 ng and 1.87 ng HBsAg for the infants of Group Ⅰ and Group Ⅱ in vivo as evaluated,respectively.The HBsAg neutralization capability of HBIG was around 20 times higher in vitro than in vivo.Conclusions The HBsAg neutralization capability of HBIG was different in vitro test vs in vivo evaluation.HBsAg levels in blood and other tissues may difference.
Objective: To evaluate the effect of short-term prophylactic antibiotics (24 h) on prevention maternal/neonatal infectious morbidity of cesarean section in patients with pelvic inflammatory disease (PID). Methods: Two hundred and twenty-seven patients with PID were collected from patients with cesarean section. Patients were divided into 2 groups according to the short-term prophylaxis (24 hours, n=109) or long-term prophylaxis (48 hours, n=118). It was compared between the two groups including maternal trimester, body mass index, white blood cell count before surgery primipara,premature rupture of membranes,pregnancy-induced hypertension syndrome and surgical site infection(SSI),postoperative endometritis,puerperal morbidity,hemogram,frequency and cost of antibiotic defined daily dose(DDDs), neonatal score and infection. Results: There were no significant differences in the basic data, before operation, duration of surgery and blood loss during surgery between two groups (P 0.05). Also there were no significant differences in the incidence of SSI, endometritis, puerperal morbidity and hemogram between two groups (P 0.05). It was found that the DDDs of short-term antibiotic prophylaxis strategy was 1/7 DDDs of long-term one (P 0.01), but no significant difference was found in the neonatal score and infection between two groups (P 0.05). Conclusion: The effect of short-term (24 hours) prophylaxis by cefazolin or combined with metronidazole was equivalent to the long-term strategies ( 48 h) in pelvic inflammatory diseases, with a decreased antibiotic usage and cost.
OBJECTIVE To evaluate the clinical effect on prophylactic antibiotics in cesarean delivery.METHODS The intervention including evidence-based guideline of prophylactic use of antimicrobial for cesarean section single-dose of the first generation cephalosporins at cord clamping was performed to increase in post-discharge surveillance as a strategy to reassure surgeons of the safety of the reduction.A retrospective investigation of antimicrobial consumption,endometritis,surgical site infections(SSIs)and postoperative incidence between the pre and post operation were performed randomly to comparison of the intervention.RESULTS The SSIs rates before and after the intervention were 1.54%,and the incidence rates of post intervention were 3.08% and 2.31%,respectively.There was about 90% cost reduction in prophylactic antimicrobial use on average per cesarean section after the intervention(RMB 179.79±51.79 to RMB 14.96±15.19,P=0.00).CONCLUSION The intervention of the first generation of cephalosporins by single-dose use administrated after cord clamping is safe and more unexpensive compared with the previous stractegy of third generation of cephalosporin plus metronidazde long use.
