OBJECTIVES:
Gram-positive cocci is the main pathogen responsible for early infection after liver transplantation (LT), posing a huge threat to the prognosis of liver transplant recipients. This study aims to analyze the distribution and drug resistance of Gram-positive cocci, the risk factors for infections and efficacy of antibiotics within 2 months after LT, and to guide the prevention and treatment of these infections.
METHODS:
In this study, data of pathogenic bacteria distribution, drug resistance and therapeutic efficacy were collected from 39 Gram-positive cocci infections among 256 patients who received liver transplantation from donation after citizens' death in the Third Xiangya Hospital of Central South University from January 2019 to July 2022, and risk factors for Gram-positive cocci infection were analyzed.
RESULTS:
Enterococcus faecium was the dominant pathogenic bacteria (33/51, 64.7%), followed by Enterococcus faecalis (11/51, 21.6%). The most common sites of infection were abdominal cavity/biliary tract (13/256, 5.1%) and urinary tract (10/256, 3.9%). Fifty (98%) of the 51 Gram-positive cocci infections occurred within 1 month after LT. The most sensitive drugs to Gram-positive cocci were teicoplanin, tigecycline, linezolid and vancomycin. Vancomycin was not used in all patients, considering its nephrotoxicity. Vancomycin was not administered to all patients in view of its nephrotoxicity.There was no significant difference between the efficacy of daptomycin and teicoplanin in the prevention of cocci infection (P>0.05). Univariate analysis indicated that preoperative Model for End-Stage Liver Disease (MELD) score >25 (P=0.005), intraoperative red blood cell infusion ≥12 U (P=0.013) and exposure to more than 2 intravenous antibiotics post-LT (P=0.003) were related to Gram-positive cocci infections. Multivariate logistic regression analysis revealed that preoperative MELD score >25 (OR=2.378, 95% CI 1.124 to 5.032, P=0.024) and intraoperative red blood cell transfusion ≥ 12 U (OR=2.757, 95% CI 1.227 to 6.195, P=0.014) were independent risk factors for Gram-positive cocci infections after LT. Postoperative Gram-positive cocci infections were reduced in LT recipients exposing to more than two intravenous antibiotics post-LT (OR=0.269, 95% CI 0.121 to 0.598, P=0.001).
CONCLUSIONS
Gram-positive cocci infections occurring early after liver transplantation were dominated by Enterococcus faecalis infections at the abdominal/biliary tract and urinary tract. Teicoplanin, tigecycline and linezolid were anti-cocci sensitive drugs. Daptomycin and teicoplanin were equally effective in preventing cocci infections due to Gram-positive cocci. Patients with high preoperative MELD score and massive intraoperative red blood cell transfusion were more likely to suffer Gram-positive cocci infection after surgery. Postoperative Gram-positive cocci infections were reduced in recipients exposing to more than two intravenous antibiotics post-LT.

Objective: Autologous peripheral blood stem cells (PBSC) derived from bone marrow can promote liver regeneration and improve the liver function of patients, but there are few studies on its effect on the long-term outcomes in patients with decompensated cirrhosis. Based on previous work, this study observed the clinical outcomes of PBSC treatment in patients with decompensated cirrhosis for 10 years, in order to provide more data support for the safety and efficacy of stem cells in clinical applications. Methods: Data of patients with decompensated liver cirrhosis who completed PBSC treatment in the Department of Gastroenterology of the First Affiliated Hospital of Air Force Military Medical University from August 2005 to February 2012 were included. The follow-up endpoint was death or liver transplantation, and patients who did not reach the follow-up endpoint were followed-up for at least 10 years. The patients with decompensated liver cirrhosis who met the conditions for PBSC treatment but did not receive PBSC treatment in our hospital during the same period were used as controls. Results: A total of 287 cases with decompensated liver cirrhosis had completed PBSC treatment, and 90 cases were lost to follow-up within 10 years after surgery. A total of 151 cases with complete survival follow-up data were included in the control group. There were no statistically significant differences in baseline information such as gender, age, etiological composition and liver function score between the two groups. The 10-year survival rate was higher in PBSC than control group (37.56% vs. 26.49%, P<0.05). Cholinesterase, albumin, international normalized ratio, Child-Turcotte-Pugh score, model for end-stage liver disease score, and other indicators were gradually recovered within 3 months to 1 year after PBSC treatment, and stabilized at a more desirable level in the long-term after follow-up for up to 10 years. There was no statistically significant difference in the incidence of liver cancer between the two groups (25.22% vs.31.85%, P=0.267). The age of onset of hepatocellular carcinoma was later in PBSC than control group [(56.66±7.21) years vs. (52.69±8.42) years, P<0.05]. Conclusions: This long-term observational follow-up study of more than ten years confirms that PBSC treatment can bring long-term benefits to patients with decompensated cirrhosis, with good long-term safety, thus providing more data support on the safety and efficacy of stem cells for clinical applications.

3.Expert consensus of perioperative management in pediatric liver transplantation.
Chinese Journal of Surgery 2021;59(3):179-191
Pediatric liver transplantation (PLT) is an effective strategy of treating various acute or chronic end-stage liver diseases and inherited metabolic diseases in children.PLT has been applied in many transplant centers nationwide and has achieved satisfactory results.However,the development of transplant centers is uneven,and there is a lack of consensus and standards within the industry.In order to reduce post-operative complications,accelerate post-operative recovery,and improve the short-and long-term quality of life of children,the Enhanced Recovery After Surgery Committee of Chinese Research Hospital Association organized multidisciplinary experts to summarize the progress of domestic and international research,and formulated a perioperative consensus on PLT based on the principles of evidence-based medicine.The consensus provides recommendations for perioperative PLT from three aspects:preoperative assessment and preparation,intraoperative management and postoperative management,in order to provide reference guidelines for centers that are conducting or preparing to conduct PLT.

Liver fibrosis is a slow, insidious process involving accumulation of extracellular matrix protein in the liver. The stage of liver fibrosis in chronic liver disease (CLD) determines overall morbidity and mortality; the higher the stage, the worse the prognosis. Noninvasive composite scores can be used to determine whether patients with CLD have significant or advanced fibrosis. Patients with low composite scores can be safely followed up in primary care with periodic reassessment. Those with higher scores should be referred to a specialist. As the epidemic of diabetes mellitus, obesity and non-alcoholic fatty liver diseases is rising, CLD is becoming more prevalent. Easy-to-use fibrosis assessment composite scores can identify patients with minimal or advanced fibrosis, and should be an integral part of decision-making. Patients with cirrhosis, high composite scores, chronic hepatitis B with elevated alanine aminotransferase and aspartate aminotransferase, or deranged liver panel of uncertain aetiology should be referred to a specialist.

5.Expert consensus on diagnosis and treatment of end-stage liver disease complicated with infections.
Chinese Journal of Hepatology 2018;26(8):568-578
End-stage liver disease (ESLD) is a life threaten clinical syndrome with significantly increasing mortality when patients complicated with infections. For patients with ESLD, infections can induce or aggravate the occurrence of liver decompensation. In turn, infections are among the most common complications under, disease progression. There is lacking of working procedures for early diagnosis and appropriate management for patients of ESLD complicated with infections, neither guidelines nor consensus at home and abroad. This consensus assembled up-to-date knowledge and experience across Chinese colleagues, providing principles as well as working procedures for clinicians to diagnose and treat an ESLD patient complicated with infections.

OBJECTIVETo investigate the predictive value of pediatrics end-stage liver disease (PELD) or the model for end-stage liver disease (MELD) in the prognosis of pediatric acute liver failure (PALF) treated with artificial liver support system (ALSS).
METHODThe clinical data of 47 children with acute liver failure seen from August 2008 to July 2013 treated in Children's Hospital, Fudan University were analyzed. Thirty children were treated with ALSS in addition to conventional comprehensive medical treatment (ALSS group). Seventeen children were treated with only conventional comprehensive medical treatment (control group). The main biochemical parameters and coagulation function parameters before and after treatment were compared in the ALSS group and the mortality rates were compared between the two groups. The patients were graded by PELD or MELD when they were hospitalized and the relationship of PELD or MELD scores and mortalities of child patients with the receiver operating characteristic curve (ROC) were analyzed.
RESULTThere were significant differences in total bilirubin (TB) ((302 ± 208) vs. (161 ± 129) µmol/L); alanine aminotransferase (ALT) ((161 ± 225) vs. (761 ± 834) U/L); aspartate aminotransferase ( AST) (66 (35, 123 ) vs. 447 (184, 1,129 ) U/L) ; international normalized ratio (INR) ((2.6 ± 1.6) vs. (5.1 ± 4.0)); prothrombin time activity percentage (PTA) ((42 ± 25)% vs. (22 ± 13)%); albumin( ALB) ((35 ± 5) vs. (33 ± 6) g/L) in the ALSS group after treatment. Through the ROC curve analysis, the best PELD/MELD threshold was 25 to predict the patients survival after ALSS therapy, with a sensitivity of 92. 3% , and a specificity of 94.1% at the cutoff point. The area under the ROC curve was 0. 912. The mortality of patients with PELD or MELD score below 25 in the ALSS group (1/13) was lower than the control group (3/4) (P = 0.022), and the mortality of patients with PELD or MELD score over 25 (16/17) was higher than that of the control group (10/13) (P = 0.290).
CONCLUSIONPELD or MELD score is a valid index in prognostic evaluation of ALSS therapy, which may provide an evidence for the therapeutic strategies of PALF. Patients with PELD or MELD score below 25 treated with ALSS obtained more benefit.

OBJECTIVETo evaluate the clinical efficacy and safety of integrative medical program based on blood cooling and detoxification recipe (BCDR) in treating patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) of heat-toxicity accumulation syndrome (HTAS).
METHODSAdopting randomized controlled clinical design, a total of 105 HBV-ACLF patients of HTAS were randomly assigned to the trial group (64 cases) and the control group (41 cases). Patients in the control group were treated with comprehensive Western therapy, while those in the trial group were treated with comprehensive Western therapy plus BCDR. All were treated for 8 weeks and followed up for 40 weeks. Effect and safety of the treatment were assessed, including fatality, liver functions [total bilirubin (TBIL), albumin (ALB), alanine aminotransferase (ALT), and aspartate transaminase (AST)], and prothrombin activity (PTA) after treatment and at week 48 of follow-ups.
RESULTSAfter 8-week treatment, there was statistical difference in the overall fatality rate (15.63% vs 34.15%), the fatality rate in the mid-term (25.0% vs 64.7%), TBIL at week 8 (64.54 +/- 79.75), AST [at week 2: (178.97 +/- 44.24) U/L vs (288.48 +/- 58.49) U/L; at week 4: (61.65 +/- 27.36) U/L vs (171.12 +/- 89.11) U/L] and PTA [at week 4: (58.30 +/- 15.29) vs (42.56 +/- 15.27); at week 6: (60.77 +/- 20.40) vs (43.08 +/- 12.79)] (all P < 0.05). At week 48 of the followup, the fatality rate of the trial group (21.88%) decreased by 17. 14% when compared with that of the control group (39.02%; P < 0.05). No obvious adverse event occurred in the two groups during the 8-week treatment period.
CONCLUSIONBCDR could significantly reduce the mortality of HBV-ACLF patients.

BACKGROUND: High model for end-stage liver disease (MELD) scores (> or =35) is closely associated with poor posttransplantation outcomes in patients who undergo living donor liver transplantation (LDLT). There is little information regarding factors that negatively impact the survival of patients with high MELD scores. The aim of this study was to identify factors associated with 3-month mortality of patients after LDLT. METHODS: We retrospectively analyzed 774 patients who underwent adult LDLT with right lobe grafts between 1996 and 2012. Exclusion criteria were re-transplantation, left graft, auxiliary partial orthotopic liver transplantation, and inadequate medical recording. Preoperative variables were analyzed retrospectively. RESULTS: The overall 3-month survival rate was 92%. In univariate analysis, acute progression of disease, severity of hepatic encephalopathy, Child-Pugh class C, hepatorenal syndrome, use of continuous renal replacement therapy, use of ventilator, intensive care unit (ICU) care before transplantation, and MELD scores > or =35 were identified as potential risk factors. However, only ICU care before transplantation and MELD scores > or =35 were independent risk factors for 3-month mortality after LDLT. Three-month and 1-year patient survival rates for those with no risk factors were 95.5% and 88.6%, respectively. In contrast, patients with at least one risk factor had 3-month and 1-year patient survival rates of 88.4% and 81.1%, respectively, while patients with two risk factors had 3-month and 1-year patient survival rates of 55.6% and 55.6%, respectively. CONCLUSIONS: Patients with both risk factors (ICU care before LDLT and MELD scores > or =35) should be cautiously considered for treatment with LDLT.

OBJECTIVETo investigate the efficacy of hematopoietic stem cell (HSC) transplantation via the hepatic artery vs. the portal vein for end-stage liver disease (ESLD).
METHODSPatients with hepatic decompensation were prospectively recruited from September 2010 to September 2012 to receive HSC transplantation via the hepatic artery or the portal vein. Liver function was examined at 3, 6, and 12 months after transplantation. Liver biopsy Results were analyzed using the Knodell score.
RESULTSEighty patients (58 males and 22 females) were enrolled in the study. The Child-Pugh score was grade B in 69 cases, and grade C in the remaining 11 cases. HSC transplantation was performed via the portal vein in 36 patients and via the hepatic artery in 44 patients. ALT levels decreased while serum albumin levels increased significantly in both groups at 6 and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Total bilirubin levels decreased significantly in both groups at 3, 6, and 12 months after HSC transplantation (P<0.05 compared with pre-transplantation levels). Additionally, prothrombin time decreased in both groups at 12 months after HSC transplantation (P<0.05 compared with pre-transplantation level). There were no significant differences in ALT, total bilirubin and prothrombin time between the two groups either before or after transplantation. Moreover, Knodell score decreased significantly at 6 and 12 months. Histological examination showed that liver cell edema, degeneration, necrosis, and inflammation were significantly relieved at 3, 6, and 12 months after transplantation. The incidence of portal vein thrombosis, upper gastrointestinal bleeding, and hepatic encephalopathy were 1.25%, 3.75%, and 2.5% respectively. The one-year survival rate was 100%.
CONCLUSIONSAutologous HSC transplantation improves liver function and histology in ESLD patients. The administration route of HSC has no significant impact on the efficacy of transplantation.
