ABSTRACT
Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.
ABSTRACT
Objective:To evaluate neutrophil/lymphocyte ratio(NLR) and the model for end-stage liver disease-sodium(MELD-Na)score in predicting short-term prognosis of patients with HBV-related acute-on-chronic liver failure(HBV-ACLF).Methods:A total of 234 consecutive HBV-ACLF patients(194 males and 40 females, aged 23-85 years)admitted to Hangzhou Xixi Hospital from January 2019 to December 2021 were enrolled. According to the 12-week clinical outcomes, patients were divided into good prognosis group( n=141)and poor prognosis group( n=93). Univariate and multivariate Logistic regression were performed to identify independent risk factors for poor prognosis of HBV-ACLF patients. Receiver operating characteristics(ROC)curve was applied to evaluate the accuracy of risk factors in predicting short-term prognosis of HBV-ACLF patients. Results:The age [(48.7±11.9) vs. (52.5±9.9) years old, t=-2.59, P=0.011], proportion of males [78.0%(110/141) vs. 90.3%(84/93), χ2=5.99, P=0.014], total bilirubin[202.9(141.2, 287.6) vs. 320.0(224.4, 400.0) μmol/L, Z=-5.14, P<0.001], creatinine [71.0(59.0, 78.0) vs. 81.0(64.0, 111.0)μmol/L, Z=-3.98, P<0.001], international normalized ratio[1.66(1.52, 1.86) vs. 1.91(1.66, 2.27), Z=-5.46, P<0.001], leukocyte count[5.16(3.99, 6.95)×10 9/L vs. 6.57(4.83, 8.30)×10 9/L, Z=-4.14, P=0.001], NLR[2.77(2.02, 3.55) vs. 5.48(3.44, 8.53), Z=-8.48, P<0.001], MELD score[22.0(20.0, 24.0) vs. 26.0(24.0, 29.0), Z=-9.22, P<0.001], MELD-Na score[22.8(20.0, 25.6) vs. 29.0(25.0, 36.0), Z=-9.16, P<0.001], liver cirrhosis[77.3%(109/141) vs. 88.2%(82/93), χ2=4.41, P=0.036], hepatorenal syndrome[4/141(2.8%) vs. 12/93(12.9%), χ2=8.91, P=0.003] and the proportion of artificial liver treatment[21/141(14.9%) vs. 24/93(25.8%), χ2=4.30, P=0.038] were significantly elevated in poor prognosis group compared with survival group. Logistic regression analysis showed that NLR( OR=3.76, 95 %CI: 2.10-6.74, P<0.001)and MELD-Na score( OR=2.24, 95 %CI: 1.17-4.29, P=0.015) were independent risk factors for poor short-term prognosis of HBV-ACLF patients. The area under the ROC curve(AUC)of NLR, and MELD-Na for the short-term prognosis of HBV-ACLF patients was 0.792 and 0.822, respectively. The AUC of the combination of NLR with MELD-Na was 0.858, which was significantly higher than that of NLR( Z=-3.04, P=0.001) or MELD-Na score( Z=-2.16, P=0.031)alone. Based on the cut-off value of the combined model, patients were classified into high combined model score (≥0.04) group and low combined model score (<0.04) group, the survival rate of the high group was significantly higher than that of the low group( χ2=67.47, P<0.001). Conclusions:NLR and MELD-Na score are independent risk factors of the short-term prognosis of HBV-ACLF patients. The combination of NLR and MELD-Na score will be beneficial to predict the short-term prognosis of HBV-ACLF patients.
ABSTRACT
Hepatic venous pressure gradient (HVPG) is the "gold standard" for the diagnosis of portal hypertension, which could be applied in the evaluation of liver cirrhosis. Combined use of HVPG with model for end-stage liver disease (MELD) scoring system may more accurately match the donors and recipients undergoing liver transplantation for liver cirrhosis, select the appropriate timing of surgery, and provide guidance for bridging treatment for patients on the waiting list for liver transplantation. Besides, HVPG may also predict clinical prognosis of liver transplant recipients, and provide evidence for early detection and intervention of potential complications. Therefore, the value of HVPG in preoperative evaluation and prognosis prediction of liver transplant recipients was reviewed, aiming to provide guidance for clinical diagnosis and treatment of liver transplant recipients before and after surgery.
ABSTRACT
Objective:To evaluate the value of preoperative aspartate aminotransferaseto platelet ratio index (APRI) and fibrosis index 4 (Fib4) in predicting posthepatectomy liver failure (PHLF) of primary hepatocellular carcinoma.Methods:The data of 587 patients with hepatocellular carcinoma admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2014 to January 2020 were retrospectively collected and analyzed, including 412 males and 175 females, aged (56.8±11.2) years. Univariate and multivariate logistic regression were used to analyze the influencing factors of PHLF. The ability of Child-Pugh score, model for end-stage liver diseas (MELD) score, APRI and Fib4 to predict PHLF was evaluated through the receiver operating characteristic (ROC) curve of subjects.Results:Among 587 patients, 186 (31.7%) had liver failure after hepatectomy. In multivariate logistic regression analysis, APRI ( OR=2.660, 95% CI: 1.314-5.384, P=0.007) and Fib4 ( OR=1.322, 95% CI: 1.157-1.511, P<0.001) were risk factors for PHLF in patients with hepatocellular carcinoma. The higher the number, the greater the risk of PHLF. The predicted area under the ROC curve of PHLF in patients with hepatocellular carcinoma was Fib4(0.719)>APRI(0.686)>MELD score(0.618)>Child-Pugh score(0.565). Conclusion:APRI and Fib4 were risk factors of PHLF in patients with hepatocellular carcinoma. They predict the occurrence of PHLF better than Child-Pugh score and MELD score.
ABSTRACT
Objective:To analyze the predictive ability of model for end-stage liver disease (MELD)-sarcopenia score in short-term prognosis of patients with acute-on-chronic liver failure (ACLF).Methods:Two hundred and seventy-one patients with ACLF hospitalized in Tianjin Third Central Hospital from January 2013 to December 2019 were selected, among whom 157 cases with sarcopenia and 114 cases without sarcopenia.According to ACLF classification, the patients were divided into group A (no cirrhosis basis) of 61 cases, group B (compensated cirrhosis basis) of 99 cases, and group C (previous history of uncompensated cirrhosis) of 111 cases.The basic data, laboratory examination results, computed tomography (CT) examination results and prognosis of the patients were retrospectively collected, and the MELD score, MELD-Na score and MELD-sarcopenia score were calculated. Multivariate logistic regression, multivariate Cox proportional hazards regression, Kaplan-Meier method, log-rank method and area under receiver operating characteristic curve were used for statistical analysis.Results:Low body mass index (odds ratio ( OR)=0.93, P<0.001), complicated cirrhosis ( OR=1.14, P=0.004), complicated hepatic encephalopathy ( OR=1.31, P<0.001), high white blood cell level ( OR=1.18, P=0.009) and high platelet level ( OR=1.08, P<0.001) were independent risk factors for sarcopenia in patients with ACLF. High MELD score (hazard ratio ( HR)=1.02, P=0.001), high MELD-Na score ( HR=1.07, P=0.038), high MELD-sarcopenia score ( HR=1.14, P<0.001), high total bilirubin ( HR=1.00, P<0.001) and high international normalized ratio (INR) ( HR=1.71, P<0.001) were independent risk factors for death in patients with ACLF. In subgroup analysis, the cumulative survival rate of sarcopenia patients in group A and B was lower than that of non-sarcopenia patients ( χ2=5.97 and 8.34, respectively, P=0.015 and 0.004, respectively), while there was no significant difference in the cumulative survival rate between sarcopenia patients and non-sarcopenia patients in group C ( χ2=4.90, P=0.053). In groups A and B, the area under the curve (AUC) of MELD-sarcopenia score in predicting short-term prognosis was 0.87, which was higher than MELD score (0.78) and MELD-Na score (0.78), and the differences were both statistically significant ( Z=2.86 and 2.56, respectively, P=0.004 and 0.011, respectively). The AUC of MELD-Na score in predicting short-term prognosis in group C (0.83) was higher than that of MELD score (0.71) and MELD-sarcopenia score (0.69), and the differences were both statistically significant ( Z=2.52 and 2.64, respectively, P=0.012 and 0.008, respectively). Conclusions:Patients with ACLF with no cirrhosis basis or compensated cirrhosis basis complicated with sarcopenia have shorter survival time and worse prognosis than those without sarcopenia. For patients with ACLF with no cirrhosis basis or compensated cirrhosis basis, MELD-sarcopenia score has better predictive value for the short-term prognosis.
ABSTRACT
Objective To explore the predictive values of the initial model for end-stage liver disease (MELD) score, MELD combined with serum sodium (MELD-Na) score and MELD combined with serum lactic acid (MELD-Lac) score for early survival rate after liver transplantation in patients with liver failure. Methods Clinical data of 135 recipients undergoing liver transplantation for liver failure were retrospectively analyzed. All patients were divided into the early survival group (n=110) and early death group (n=25) according to the survival at postoperative 28 d. Clinical data were compared between two groups. The optimal cut-off values of MELD, MELD-Na and MELD-Lac scores for predicting early survival rate after liver transplantation in patients with liver failure were determined by the receiver operating characteristic (ROC) curve. The predictive values of different scores for early survival rate after liver transplantation in patients with liver failure were evaluated. Results Significant differences were observed in the initial MELD, MELD-Na and MELD-Lac scores after liver transplantation between two groups (all P < 0.05). For the initial MELD, MELD-Na and MELD-Lac scores in predicting early survival rate after liver transplantation in patients with liver failure, the AUC were 0.653 [95% confidence interval (CI) 0.515-0.792], 0.648 (95%CI 0.514-0.781) and 0.809 (95%CI 0.718-0.900), the optimal cut-off values were 18.09, 18.09 and 19.97, Youden's indexes were 0.398, 0.380 and 0.525, the sensitivity was 0.680, 0.680 and 0.840, and the specificity was 0.720, 0.700 and 0.690, respectively. The AUC of MELD-Lac score was higher than those of MELD and MELD-Na scores, and the differences were statistically significant (both P < 0.05). Conclusions Compared with the initial MELD and MELD-Na scores after liver transplantation, the initial MELD-Lac score is a more reliable index for predicting early survival rate after liver transplantation in patients with liver failure.
ABSTRACT
Objective To evaluate the predictive values of albumin-bilirubin (ALBI) and easy albumin-bilirubin (EZ-ALBI) scores for early survival (postoperative 3 months) of recipients with liver failure after liver transplantation. Methods Clinical data of 137 recipients diagnosed with liver failure and underwent liver transplantation were retrospectively analyzed. The optimal cut-off values of preoperative ALBI, EZ-ALBI and MELD scores to predict early survival of recipients with liver failure after liver transplantation were determined by the area under the receiver operating characteristic (ROC) curve. The risk factors of early death of recipients with liver failure after liver transplantation were identified by univariate and multivariate Cox regression analyses. The effects of different ALBI and EZ-ALBI levels upon early prognosis of recipients with liver failure after liver transplantation were analyzed. Results The optimal cut-off values of ALBI, EZ-ALBI and MELD scores were 0.21, -19.83 and 24.36, and the AUC was 0.706, 0.697 and 0.686, respectively. Univariate Cox regression analysis showed that preoperative alanine aminotransferase(ALT)≥50 U/L, aspartate aminotransferase(AST)≥60 U/L, ALBI score≥0.21 and EZ-ALBI score≥-19.83 were the risk factors for early postoperative death of recipients with liver failure after liver transplantation (all P < 0.05). Multivariate Cox regression analysis demonstrated that preoperative ALBI score≥0.21 was an independent risk factor for early postoperative death of recipients with liver failure after liver transplantation (P < 0.05). According to the optimal cut-off value of ALBI score, the early survival rates in the ALBI < 0.21 (n=46) and ALBI≥0.21(n=91) groups were 93.5% and 64.8%, and the difference was statistically significant (P < 0.05). According to the optimal cut-off value of EZ-ALBI score, the early survival rates in the EZ-ALBI < -19.83(n=60) and EZ-ALBI≥-19.83(n=77) groups were 88.3% and 63.6%, and the difference was statistically significant (P < 0.05). Conclusions Preoperative ALBI score is of high predictive value for early survival of recipients with liver failure after liver transplantation, which could be utilized as a reference parameter for selecting liver transplant recipients.
ABSTRACT
Drug-induced liver injury (DILI) is a type of necrotizing and inflammatory liver disease caused by certain commonly-used drugs, Chinese herbal medicines or dietary supplements. In severe cases, it may lead to acute liver failure. Without liver transplantation, the fatality could reach up to 80%. It is of significance to master the indications of liver transplantation. Several prognostic scoring systems have been developed to help clinicians to decide which patients need urgent liver transplantation, such as King's College criteria (KCC) and model for end-stage liver disease (MELD) scoring systems. However, these scoring methods have been developed for a long period of time and lack of modifications. Therefore, scholars have proposed several new scoring systems, such as acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) scoring systems, which provide novel ideas for the evaluation of liver transplantation. As an important treatment measure for drug-induced acute liver failure, urgent liver transplantation has greatly improved the survival rate of patients. In this article, the classification, clinical diagnosis, liver transplantation evaluation and prognosis of DILI were summarized, aiming to provide reference for the treatment of DILI by liver transplantation.
ABSTRACT
Acute-on-chronic liver failure (ACLF) is a specific category of liver failure, which is mainly characterized by rapid progression and multiple organ failure. At present, patients with ACLF are mainly given with systematic and comprehensive medical therapy to promote liver regeneration. However, liver transplantation is the only potentially curative treatment for patients who failed to respond to medical treatment and rapidly progress into multiple organ failure. Considering the differences of disease progression and clinical prognosis, and the shortage of donor liver in China, it is necessary to actively prevent the triggering factors of ACLF in patients with chronic liver diseases, screen out the recipients who are most likely to benefit from liver transplantation and deliver precision management during perioperative period of liver transplantation. In this article, the application of liver transplantation in ACLF was illustrated from the perspectives of accurate evaluation of ACLF, proper control of liver transplantation indications and meticulous perioperative management, aiming to optimize the therapeutic strategy of liver transplantation in patients with ACLF.
ABSTRACT
Objective:To study the use of different assessment methods in predicting perioperative outcomes in patients with acute cholecystitis and decompensated cirrhosis.Methods:A retrospective study was performed on 28 patients with acute cholecystitis and decompensated cirrhosis (MELD ≥ 15) who underwent laparoscopic surgical intervention from January 2016 to August 2020 at the Third People Hospital of Xinjiang Uygur Autonomous Region. These patients were divided into 2 groups according to the severity of acute cholecystitis grading in the Tokyo Guidelines 2018 (TG18): TG18 grade Ⅰ for the mild cholecystitis group ( n=15) and TG18 grade Ⅱ and grade Ⅲ for the moderate and severe cholecystitis group ( n=13). 16 patients with a MELD score ranging from 5 to 15 and with TG18 grade Ⅰ were used as the control group. The operation-related conditions, surgical injuries and surgical complications were compared among the three groups. Results:Of 44 patients with acute cholecystitis and decompensated cirrhosis included in this study, there were 28 males and 16 females, aged (57.3±5.9) years. Significantly more patients in the moderate and severe cholecystitis group (13/13) suffered from cholecystitis due to stone impaction than the control group (11/16) and the mild cholecystitis group (10/15) ( P<0.05). When compared to the control group, patients in the mild cholecystitis group and the moderate and severe cholecystitis group had significant increases in operative time, intraoperative bleeding, amount of abdominal drainage, abdominal drainage time, delayed feeding time and hospital stay ( P<0.05). These perioperative outcomes were further and significantly increased in the moderate and severe cholecystitis group when compared to the mild cholecystitis group ( P<0.05). The blood bilirubin levels, blood creatinine levels and MELD scores after surgery were significantly better in both the mild cholecystitis group and the moderate and severe cholecystitis group on postoperative day 3 when compared to those before treatment ( P<0.05). The Child score was significantly better in the control group after surgery than that before surgery ( P<0.05). The grade Ⅰ-Ⅱ surgical complication rate was significantly higher in the moderate and severe cholecystitis group (11/13) than the mild cholecystitis group (5/15, χ 2=7.479), and the control group (4/16, χ 2=10.208) ( P<0.05). There were no significant differences in the grade Ⅲ-Ⅴ surgical complication rates among the three groups (all P>0.05). The overall surgical complication rate was significantly higher in the moderate and severe cholecystitis group (12/13) than the mild cholecystitis group (7/15, χ 2=7.385), and the control group (5/16, χ 2=11.023), (all P<0.05). Conclusions:The MELD score when combined with the severity grading for acute cholecystitis of the TG18 was effective to evaluate the perioperative risks of patients with acute cholecystitis and decompensated cirrhosis. Patients with a MELD score ≥ 15 and TG18 Ⅱ or Ⅲ had significantly higher risks after minimally invasive surgery.
ABSTRACT
Objective:To investigate the prognosis value of the Child-Turcotte-Pugh (CTP), pediatrics end-stage liver disease/model for end-stage liver disease(PELD/MELD) and sequential organ failure assessment (SOFA) scores in pediatric acute liver failure (PALF) at 28 th day. Methods:Fifty-four PALF patients admitted in the Pediatric Intensive Care Unit (PICU) and Infection Department of Pediatrics, Qingdao Women′s and Children′s Hospital from June 1, 2012 to June 1, 2019 were included in the study.According to the survival of PALF patients on the 28 th day, they were divided into the survival group (28 cases) and the death group (26 cases). Baseline characte-ristics and laboratory examination data of PALF patients in both groups were collected and compared.Receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of CTP, PELD/MELD and SOFA scores in PALF. Results:The mortality rate of 54 PALF patients was 48.1%.Compared with the survival group, PALF patients in the death group were significantly younger than those in survival group [11.0(3.8-39.0) months vs.14.5(7.3-84.0) months]( Z=-2.145, P=0.020). In addition, CTP, PELD/MELD and SOFA scores were significantly higher in the death group than those in survival group [14.0(11.7-15.0) vs.9.0(7.0-10.0), 32.0(29.0-36.0) vs.25.0(22.0-26.0), 13.0(11.0-16.0) vs.6.0(4.0-7.0)]( Z=-5.095, -4.894, -5.502, all P<0.05). Serum lactate level, blood ammonia level, total bilirubin, direct bilirubin and international normalized ratio were significantly higher in the death group than those in survival group [3.4(2.1-5.3) mmol/L vs.1.5(0.8-2.3) mmol/L, 69.5(46.9-102.9) μmol/L vs.41.7(27.3-50.3) μmol/L, 173.0(97.0-237.2) μmol/L vs.71.9(62.0-136.9) μmol/L, 132.3(53.6-206.2)μmol/L vs.59.3(62.0-99.7) μmol/L, 2.6(1.8-3.5) vs.1.7(1.5-1.9)]( Z=-4.027, -3.220, -2.649, -2.648, -3.807, all P<0.05). Prothrombin time (PT) was significantly prolonged in the death group than that of survival group [27.5(19.2-41.9)s vs.17.8(16.9-22.2)s]( Z=-3.489, P<0.05). Compared with those of survival group, serum albumin, alanine transaminase (ALT) and alpha fetoprotein (AFP) levels were significantly lower in the death group [(30.9±1.0) g/L vs.(33.6±0.9) g/L, 379.2(163.3-880.3) U/L vs.962.5(457.0-1 657.3) U/L, 7.5(0.7-115.8) μg/L vs.22.1(7.9-91.3) μg/L]( t=2.049, Z=-2.510, -2.342, respectively, all P<0.05). The incidence of alimentary tract hemorrhage was significantly higher in the death group than that of survival group (22/26 cases vs.11/28 cases)( χ2=13.340, P<0.05). The cut-off value of CTP, PELD/MELD and SOFA scores in predicting the prognosis of PALF were 11.5, 28.5 and 10.0, respectively.Among the three scoring systems, the specificity and positive predictive value of SOFA scores remained the highest.The sensitivity and specific of a combination of three scoring systems in predicting the prognosis of PALF were 92.3% and 89.3%, respectively, and its Youden index was the highest than that of a single scoring of either CTP, PELD/MELD or SOFA ( Z=2.19, P<0.05). Conclusions:CTP, PELD/MELD and SOFA scores have high predictive value for the short-term prognosis of PALF.The combined detection of the three scoring systems can improve the forecasting efficiency of PALD.
ABSTRACT
Background: Liver cirrhosis is one of the most common causes of morbidity and mortality. The availability of liver transplant has stressed on the need for accurate prognostication. Various scoring systems have been developed for the same and studies have been conducted to find the correlation of various biochemical parameters with these.Methods: This is a cross sectional study conducted on 100 patients with stigmata of liver cell failure on clinical examination and substantiated by imaging. Serum Uric acid and other biochemical parameters were determined. Child Turcotte Pugh Score, Model for End Stage Liver Disease (MELD) score, United Kingdom Model for End Stage Liver Disease (UKELD) score was calculated and the correlation obtained.Results: The study showed significant, positive correlation between uric acid level and CTP, MELD and UKELD score. The study also showed the positive correlation of serum uric acid with various biochemical parameters such as total bilirubin, Prothrombin time/ International Normalized Ratio (PT/INR) and serum creatinine and negative correlation with serum albumin, with a significant p value. The mean serum uric acid was found to be 4.79(4.79± 2.0)Conclusions: The study showed a correlation between serum uric acid and the various available scoring systems such as CTP score, MELD and UKELD score. Hence serum uric acid can be used as an alternative prognostic parameter in predicting the severity and prognosis of cirrhosis of liver.
ABSTRACT
Background: Liver cirrhosis is the end result of chronic liver injury and is one of the most common cause of morbidity and mortality. Several scorings are available to predict the severity and prognosis of liver cirrhosis. This study aims to calculate APRI index, MELD score and child Pugh score in cirrhosis patients and to find the correlation between them.Methods: This is the Cross-sectional study on 100 patients confirmed with cirrhosis of liver. Cirrhosis due to alcohol, Hepatitis B and C, autoimmune, Cryptogenic, NAFLD, were included in the study. APRI Index, MELD Score and Child Pugh Score were calculated, and the correlation was obtained.Results: This study found out the relationship between APRI index, MELD Score and Child Pugh Score with significant p value. The study also showed that all the three scores were raised with patients who had complication of cirrhosis like encephalopathy, refractory ascites. Among those who had complication like grade 3 or 4 encephalopathy, APRI index had a mean value of 3.4, Child Pugh had a mean score of 13.2, and MELD had a mean score of 36.08 with standard deviation of 2.0, 1.5, 6.0 respectively.Conclusions: APRI index is an independent predictor of morbidity and mortality. The prognostic performance of all 3 was comparable, Hence APRI index can be used as an alternative scoring which is cost effective and objective method in predicting the severity and prognosis in cirrhosis of liver.
ABSTRACT
Objective To investigate the rationality and efficacy of enhanced recovery after surgery (ERAS) in liver transplant recipients. Methods Clinical data of 465 liver transplant recipients were retrospectively analyzed. All recipients were divided into the ERAS group (n=163) and control group (n=302) according to whether they received ERAS. The severity of disease in the ERAS group was worse than that in the control group. Operation situations including the operation time, anhepatic phase and intraoperative blood transfusion volume of the liver transplant recipients were observed and recorded. Postoperative recovery conditions including the length of intensive care unit (ICU) stay, total length of hospital stay, total ventilator removal time at postoperative 28 d and postoperative re-intubation rate were recorded. The survival rates at 90 d, 180 d and 1 year after liver transplantation were calculated. The influencing factors of survival rate of liver transplant recipients were analyzed. Results The anhepatic phase in the ERAS group was 45 (39, 53) min, significantly longer than 40 (32, 48) min in the control group (P < 0.05). The volume of erythrocyte infusion in the ERAS group was 10 (7, 13) U, significantly less than 18 (10, 28) U in the control group (P < 0.05). The length of postoperative ICU stay and total length of hospital stay in the ERAS group were 135 (84, 212) h and 24 (18, 33) d, significantly shorter than 154 (103, 253) h and 34 (20, 50) d in the control group (both P < 0.05). Total ventilator removal time at postoperative 28 d was 26 (25, 27) d, significantly longer than 26 (23, 27) d in the control group (P < 0.05). The postoperative re-intubation rate in the ERAS group was 11.0%, significantly lower than 20.8% in the control group (P < 0.05). The 90 d, 180 d and 1-year survival rates in the ERAS group were 92.8%, which were significantly higher than 81.1%, 78.1% and 75.7% in the control group (all P < 0.05). ERAS and operation time were the independent influencing factors of survival rate of liver transplant recipients (both P < 0.05). Conclusions ERAS after liver transplantation can improve the survival rate of recipient, shorten the length of hospital stay, reduce the re-intubation rate and accelerate the rehabilitation after liver transplantation.
ABSTRACT
Objective To explore the early prognosis and the risk factors of delayed graft function (DGF) of the recipients undergoing liver transplantation from donor liver with moderate-to-severe steatosis. Methods Clinical data of 475 donors and 475 recipients undergoing liver transplantation from donor liver of organ donation after citizen's death were retrospectively analyzed. According to the classification criteria of steatosis proposed by Australia National Liver Transplantation Unit (ANLTU), all recipients were divided into the S0 group (no steatosis, n=308), S1 group (mild steatosis, n=97), S2 group (moderate steatosis, n=52) and S3 group (severe steatosis, n=18), respectively. The early postoperative death and incidence of postoperative complications were statistically compared among each group. The risk factors from donors, recipients and operation leading to DGF were analyzed by univariate and multivariate logistic regression models. Results The incidence of postoperative DGF in the S2 and S3 groups was significantly higher than that in the S1 and S0 groups (all P < 0.05). The incidence of postoperative DGF in the S3 group was remarkably higher than that in the S2 group (P < 0.05). The early postoperative fatality, the incidence of primary nonfunction (PNF) of the transplant liver, postoperative bleeding, infection, biliary complications and vascular complications did not significantly differ among each group (all P > 0.05). Univariate regression analysis showed that severe steatosis of donor liver, long cold ischemia time, high model for end-stage liver disease (MELD) score and tumors of the recipients before operation were the risk factors of DGF (all P < 0.05). Multivariate logistic regression analysis demonstrated that moderate-to-severe steatosis of donor liver, cold ischemia time > 8 h and MELD score > 30 of the recipients were the independent risk factors for early postoperative DGF. Conclusions The early-stage incidence of DGF after adult liver transplantation from donor liver with moderate-to-severe steatosis is high, whereas it does not affect the early survival rate of the recipients. The selection of donor liver with moderate-to-severe steatosis should be considered in combination with cold ischemia time of the donors and MELD score of the recipients before operation, etc.
ABSTRACT
ObjectiveTo investigate the value of Model for End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP) score in predicting the prognosis of patients with hepatic sinusoidal obstruction syndrome (HSOS) associated with Gynura segetum (Lour.) Merr. MethodsA total of 49 patients with HSOS associated with Gynura segetum (Lour.) Merr. who were admitted to Beijing YouAn Hospital, Beijing Ditan Hospital, The Fifth Medical Center of Chinese PLA General Hospital, Tianjin Third Central Hospital, and The First Affiliated Hospital of Xinxiang Medical University from January 2012 to July 2018 were enrolled and followed up for three years, with death as the outcome event. MELD and CTP scores were calculated according to the laboratory examination and clinical data on admission, and according to CTP score, the patients were divided into CTP class A (CTP score 5-6) group(n=8), CTP class B (CTP score 7-9) group(n=23), and CTP class C (CTP score ≥10) group(n=18). The patients were divided into death group(n=12) and survival group(n=37) according to the clinical outcome during follow-up. The Mann-Whitney U test was used for comparison of continuous data between groups, and the Kruskal-Wallis H test was used for ranked data. The area under the receiver operator characteristic (ROC) curve (AUC) was used to investigate the ability of CTP and MELD scores in predicting death. The Kaplan-Meier survival curves were used to determine the long-term prognosis of patients with different CTP and MELD scores, and the log-rank test was used for comparison. The ROC curve was used to evaluate the performance of these two scoring systems in predicting death. ResultsA total of 12 patients died during the 3-year follow-up period. The patients with HSOS had a median MELD score of 13.443 (8.792-18.379), and the death group had a significantly higher MELD score than the survival group ［19.84 (15.49-25.41) vs 11.58 (8.60-15.79), Z=-3.511, P＜0.001］. The patients with HSOS had a CTP score of 6-12, and of all 49 patients, 8 (16.3%) had CTP class A HSOS, 23 (46.9%) had CTP class B HSOS, and 18 (36.7%) had CTP class C HSOS. The mortality rate of the patients increased significantly with the increase in CTP score (χ2=16.078, P＜0.05). The mortality rates of the patients with CTP class A, B, and C HSOS were 0.0%, 13.0%, and 50.0%, respectively (χ2=10343, P＜0.05). The Kaplan-Meier analysis showed that the patients with a MELD score of ＜14.294 4 had a significantly better 3-year prognosis than those with a MELD score of ≥14.294 4 (χ2=14.893, P＜0.001). The higher the CTP score, the poorer the 3-year prognosis of patients (χ2=11.083, P＜0.05). CTP class had an AUC of 0.780 (95% confidence interval ［CI］: 0.639-0.922) in predicting the prognosis of HSOS patients, while MELD score had an AUC of 0.840 (95%CI: 0.722-0.958), and there was no significant difference between the two scores (Z=2.63, P＞0.05). ConclusionBoth MELD and CTP scores can predict the risk of death in patients with HSOS, with similar performance in predicting the prognosis of patients, and further studies are needed to validate their clinical value.
ABSTRACT
Objective To compare the difference of clinical efficacy between surgical magnifying glass and surgical microscope assisted hepatic artery reconstruction in living donor liver transplantation (LDLT). Methods Clinical data of 272 donors and recipients undergoing LDLT were retrospectively analyzed. According to different patterns of hepatic artery reconstruction, all recipients were divided into the magnifying glass group (n=189) and microscope group (n=83). The operation time, intraoperative blood loss, hepatic artery reconstruction site, diameter of anastomosis, incidence of postoperative complications and survival rate of recipients were statistically compared between two groups. Results Compared with the microscope group, the operation time, hepatic artery reconstruction time and intraoperative blood loss were significantly less in the magnifying glass group (all P < 0.001). The most common site of hepatic artery reconstruction was the right hepatic artery in two groups, and the diameter of anastomosis was (2.1±0.9) mm in the magnifying glass group and (2.1±0.8) mm in the microscope group, with no statistical significance between two groups (P > 0.05). The 1-, 2- and 3-year survival rates of recipients in the magnifying glass group were 88%, 86% and 85%, which did not significantly differ from 89%, 87% and 86% in the microscope group (all P > 0.05). The incidence of postoperative complications did not significantly differ between two groups (all P > 0.05). Conclusions The efficacy and safety of hepatic artery reconstruction in LDLT under surgical magnifying glass are equivalent to those under surgical microscope, with less operation workload and intraoperative blood loss. For experienced transplantation surgeons, it is recommended to perform hepatic artery reconstruction assisted by surgical magnifying glass.
ABSTRACT
Objective To analyze the risk factors and predictors related to postoperative delirium(POD) in liver transplantation. Methods The clinical data of 232 liver transplant recipients were retrospectively analyzed. Recipients were assigned to POD group (n=60) and non-POD (n=172) group according to the presence of POD. The intra- and post-operative conditions were compared between the two groups of liver transplant recipients. The risk factors for occurrence of POD in liver transplant recipients were analyzed using multifactorial analysis. And the value of predicting the occurrence of POD in liver transplant recipients according to the risk factors were assessed. Results The incidence of POD in liver transplant recipients was 25.9%. The operation time and anhepatic phase in the POD group were longer than those in the non-POD group. Intraoperative infusion of erythrocyte, infusion of cryoprecipitate, and lactic acid level were higher than those in the non-POD group (all P < 0.05). The levels of postoperative alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time international normalized ratio (PT-INR), and plasma fibrinogen in the POD group were significantly higher than those in the non-POD group (all P < 0.05). Preoperative hepatic encephalopathy, elevated blood ammonia, high score of model for end-stage liver disease (MELD), elevated postoperative AST level and long intraoperative anhepatic phase were the independent risk factors for POD in liver transplant recipients (all P < 0.05). Preoperative elevated blood ammonia and high MELD score showed profound value in predicting the occurrence of POD in liver transplant recipients, with best cut-off values of 42.6 μmol/L and 18 points, sensitivity of 0.650 and 0.767 as well as specificity of 0.826 and 0.727, respectively. Conclusions The incidence of POD is high in liver transplant recipients. Preoperative hepatic encephalopathy, elevated blood ammonia, high MELD score, elevated postoperative AST level, and long intraoperative anhepatic phase are independent risk factors for liver transplant POD. Preoperative elevated blood ammonia and high MELD score are predictors of POD in transplant recipients.
ABSTRACT
Objective To compare the accuracy of three acute kidney injury (AKI) criteria of RIFLE, Acute Kidney Injury Network (AKIN) and Kidney Disease: Improving Global Outcomes (KDIGO) in predicting the early (30 d) postoperative death of liver transplant recipients. Methods Clinical data of 173 liver transplant recipients were retrospectively analyzed. The incidence of postoperative AKI was calculated according to the three criteria of RIFLE, AKIN and KDIGO. The all-cause fatality rate and cause of death at postoperative 30 d were analyzed. The risk factors of death within 30 d after operation were analyzed by binary Logistic regression. The prediction accuracy of three criteria for death within 30 d after operation was compared by the receiver operating characteristic (ROC) curve. Results According to the RIFLE, AKIN and KDIGO criteria, the incidences of postoperative AKI were 48.0%, 51.4% and 53.8%, respectively. Thirteen patients died within 30 d after operation and the fatality rate was 7.5%. RIFLE, AKIN and KDIGO stages were the independent risk factors for death within 30 d after operation (all P < 0.05). The area under the curve (AUC) of RIFLE, AKIN and KDIGO stages to predict death within 30 d after liver transplantation were 0.828, 0.766 and 0.844, respectively. There was a statistically significant difference between AKIN and KDIGO (P < 0.05). Conclusions KDIGO criterion is better for predicting early death after liver transplantation. However, as a tool, the comparative selection among these three criteria still needs the evidence support from a large multicenter sample.
ABSTRACT
Liver transplantation, although recognized as the only effective radical treatment for severe liver disease, might be accompanied by high surgical risks, high perioperative mortality and high postoperative complications. Considering the shortage of donor liver and related surgical risks, it is necessary to strictly control the indication of operation and the opportunity of transplantation. Therefore, accurate diagnosis and comprehensive evaluation of the condition of patients with severe liver disease to be treated by liver transplantation is an important part in determining the treatment plan. At present, there are many evaluation criteria for severe liver disease. In addition to the classic ChildTurcotte-Pugh (CTP) score and model for end-stage liver disease (MELD) score, many other evaluation criteria have also been developed. All transplant centers have their own choices and thus there is no uniform diagnostic criterion, with disputes among various criteria, which is exactly what this paper aims to summarize.
