Lactate and Bilirubin Index: A New Indicator to Predict Critically Ill Cirrhotic Patients’ Prognosis

Objectives. We aimed to perform external validation of the prognostic value of the lactate and bilirubin (LB) index, a new indicator, and compare the ability of the LB index and other scoring systems to predict both short- and long-term mortality in critically ill cirrhotic patients. Materials and Methods. A number of 479 cirrhotic patients admitted into ICU were included in our research. We measured prognostic scores in the first 24 hours including LB index, Child–Pugh, SOFA, CLIF-SOFA, and MELD scores. The LB index was calculated as follows: ln [1000 × lactate (mmol/L) × bilirubin (µmol/L)]/2. The primary outcomes were 28-day and 3-year all-cause mortality. Multivariate logistic regression analyses were used to investigate the independent association between the LB index and the mortality in critically ill cirrhotic patients. The area under the receiver operating characteristic curve was used to assess the prediction accuracy of short- and long-term mortality of the clinical score. Calibration of the score was evaluated by Hosmer–Lemeshow goodness-of-fit test for significance. Results. Multivariate logistic regression analysis identified that the LB index (odds ratio: 5.487, 95% confidence interval: 3.542–8.501, $P<0.001$ ) was the strongest predictor for 28-day mortality. The LB index gave the highest area under the curve (0.791, 95% confidence interval: 0.747–0.836) in predicting 28-day mortality. For predicting 3-year mortality, the model for end-stage liver disease (MELD) score showed better discrimination ability with an area under the curve of 0.726 (95% confidence interval: 0.680–0.771). The risk of mortality significantly increased when the clinical scores were ≥ the optimal cutoff values. Conclusions. The LB index, a simple prognostic indicator, performs well in predicting critically ill cirrhotic patients’ short-term prognosis, while, for long-term prognosis, the MELD score is more appropriate.

Global Longitudinal Strain at Rest as an Independent Predictor of Mortality in Liver Transplant Candidates: A Retrospective Clinical Study

Speckle tracking echocardiography enables the detection of subclinical left ventricular dysfunction at rest in many heart diseases and potentially in severe liver diseases. It could also possibly serve as a predictor for survival. In this study, 117 patients evaluated for liver transplantation in a single center between May 2010 and April 2016 with normal left ventricular ejection fraction were included according to clinical characteristics of their liver disease: (1) compensated (n = 29), (2) clinically significant portal hypertension (n = 49), and (3) decompensated (n = 39). Standard echocardiography and speckle tracking echocardiography were performed at rest and during dobutamine stress. Follow-up amounted to three years to evaluate survival and major cardiac events. Altogether 67% (78/117) of the patients were transplanted and 32% (31/96 patients) died during the three-year follow-up period. Global longitudinal strain (GLS) at rest was significantly increased (became more negative) with the severity of liver disease (p < 0.001), but reached comparable values in all groups during peak stress. Low (less negative) GLS values at rest (male: >−17/female: >−18%) could predict patient survival in a multivariate Cox regression analysis (p = 0.002). GLS proved valuable in identifying transplant candidates with latent systolic dysfunction.

Prognostic value of international normalized ratio to albumin ratio among critically ill patients with cirrhosis

BACKGROUND AND AIM

Critically ill patients with cirrhosis are at an increased risk of mortality. Our study aimed to externally validate the ability of the prothrombin time-international normalized ratio to albumin ratio (PTAR), an objective and simple scoring system, to predict 90-day mortality in critically ill patients with cirrhosis.

PATIENTS AND METHODS

A total of 865 patients were entered into the study, and all the participants were followed up for at least 90 days. Clinical parameters on the first day of intensive care unit admission were included to compare survivors with nonsurvivors.

RESULTS

After multivariable adjustment, the association between the risk of 90-day mortality and PTAR remained statistically significant with a hazard ratio of 2.71 (95% confidence interval: 1.99-3.68). The PTAR score showed good discrimination ability for predicting 90-day mortality with an area under receiver operating characteristic curve of 0.72 (95% confidence interval: 0.68-0.75). To improve its feasibility, we regrouped the PTAR scores into three levels of risk (low risk: <0.55, intermediate risk: 0.55-1.00, and high risk: ≥1.00); the 90-day mortality rates were 20.1% (74/368), 41.7% (168/403), and 73.4% (69/94), respectively.

CONCLUSION

The PTAR score system is a convenient and practical tool for predicting the prognosis of critically ill patients with cirrhosis.

Efficacy and safety of autologous stem cell transplantation for decompensated liver cirrhosis: A retrospective cohort study

AIM

To evaluate the long-term efficacy and safety of autologous stem cell transplantation (SCT) for decompensated liver cirrhosis.

METHODS

Consecutive patients with decompensated liver cirrhosis were included and assigned into the SCT group and non-transplantation (non-SCT) group according to whether they received SCT treatment. Patients were followed up for ten years. The long-term survival rate and incidence of hepatocellular carcinoma (HCC) were compared between groups.

RESULTS

A total of 159 patients were enrolled, including 27 cases in the SCT group and 132 cases in the non-SCT group. The baseline characteristics were significantly different between the two groups. Propensity score matching (PSM) was used to match SCT and non-SCT patients. After PSM, 92 subjects were enrolled in the final analysis, including 23 cases in the SCT group and 69 cases in the non-SCT group. The overall mortality was 73.9% and 55.1%, and the median survival period was 48 and 64 mo, respectively. However, no significant difference was found in the long-term survival rate between the two groups (P > 0.05). In addition, the incidence of HCC was higher in the SCT group than in the non-SCT group (47.8% vs 21.7%, P < 0.05). After adjusting for other covariates, SCT (OR = 3.065, 95%CI: 1.378-6.814) and age (OR = 1.061, 95%CI: 1.021-1.102) were independently correlated with the development of HCC in this decompensated liver cirrhosis cohort.

CONCLUSION

Autologous SCT may fail to improve the long-term efficacy and increase the incidence of HCC for decompensated liver cirrhosis. Close monitoring of HCC is strongly recommended in patients undergoing autologous SCT.

Effect of compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver) on serum albumin and pre-albumin levels in patients with decompensated liver cirrhosis

AIM: To observe the effect of compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver) on serum albumin (ALB) and pre-albumin (PA) levels in patients with decompensated liver cirrhosis.

METHODS: A total of 35 inpatients with decompensated liver cirrhosis were enrolled in this trial, including 20 patients treated with compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver) plus routine medical treatment, and 15 patients receiving routine medical treatment only as controls. The efficacy of compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver) was monitored during a 12-week follow-up period.

RESULTS: After treatment with compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver), serum PA and ALB levels increased gradually. PA levels at 4 wk after treatment were 110.3 mg/L ± 14.6 mg/L vs 100.8 mg/L ± 7.5 mg/L (P < 0.05) in the treatment group and control group. ALB levels at 8 wk after treatment and 31.9 g/L ± 2.5 g/L vs 29.8 g/L ± 2.1 g/L (P < 0.05) in the treatment group and control group. The efficacy continued to 12 wk after treatment.

CONCLUSION: Compound azintamide enteric-coated tablet combined with compound nutrients (Noveliver) improves the nutritional status of patients with decompensated cirrhosis, increases serum ALB and PA levels, and reduces the incidence and severity of ascites.

Measurement of serum procalcitonin levels for the early diagnosis of spontaneous bacterial peritonitis in patients with decompensated liver cirrhosis

Background

It is difficult to diagnose spontaneous bacterial peritonitis (SBP) early in decompensated liver cirrhotic ascites patients (DCPs). The aim of the study was to measure serum procalcitonin (PCT) levels and peripheral blood leukocyte/platelet (WBC/PLT) ratios to obtain an early diagnostic indication of SBP in DCPs.

Methods

Our cohort of 129 patients included 112 DCPs (94 of whom had infections) and 17 cases with compensated cirrhosis as controls. Bacterial cultures, ascitic fluid (AF) leukocyte and peripheral WBC/PLT counts, and serum PCT measurements at admission were carried out prior to the use of antibiotics. Receiver operating characteristic (ROC) curves were generated to test the accuracies and cut-off values for different inflammatory markers.

Results

Among the 94 infected patients, 66 tested positive by bacterial culture, for which the positivity of blood, ascites and other secretions were 25.8%, 30.3% and 43.9%, respectively. Lung infection, SBP and unknown sites of infection accounted for 8.5%, 64.9% and 26.6% of the cases, respectively. Serum PCT levels (3.02 ± 3.30 ng/mL) in DCPs with infections were significantly higher than those in control patients (0.15 ± 0.08 ng/mL); p < 0.05. We used PCT ≥0.5 ng/mL as a cut-off value to diagnose infections, for which the sensitivity and specificity was 92.5% and 77.1%. The area under the curve (AUC) was 0.89 (95% confidence interval: 0.84–0.91). The sensitivity and specificity were 62.8% and 94.2% for the diagnosis of infections, and were 68.8% and 94.2% for the diagnosis of SBP in DCPs when PCT ≥2 ng/mL was used as a cut-off value. For the combined PCT and WBC/PLT measurements, the sensitivity was 76.8% and 83.6% for the diagnosis of infections or SBP in DCPs, respectively.

Conclusion

Serum PCT levels alone or in combination with WBC/PLT measurements seem to provide a satisfactory early diagnostic biomarker in DCPs with infections, especially for patients with SBP.

Resource utilization and survival among Medicare patients with advanced liver disease

BACKGROUND

The prevalence of advanced liver disease and its complications may be on the rise within the Medicare population. The study aim was trend assessment for prevalence, mortality and resource utilization of patients with advanced liver disease.

METHODS

A retrospective, cross-sectional design was used to analyze a national sample of non-institutionalized Medicare in/outpatients from 2005 to 2009. Cases were ascertained by International Classification of Diseases, 9th Edition. Outcomes were overall mortality (within 1 year) and resource utilization [hospital length of stay (LOS/days) and institutional costs to Medicare]. Multivariate analyses were used to estimate the odds ratios for mortality predictors; linear regression was used for resource utilization predictors.

RESULTS

A total of 21,913 beneficiaries with advanced liver disease were identified in the Medicare inpatient and outpatient administrative data sets from 2005 to 2009. Over 70 % of the beneficiaries with advanced liver disease died during study time period with 17 % dying while hospitalized. Predictors of mortality were: admission to the intensive care unit (ICU) and increasing Charlson Comorbidity Index. Predictors for increased LOS and cost were: ICU admission and having a thoracentesis procedure (both indicators of the levels of illness).

CONCLUSIONS

Advanced liver disease and its related complication are increasing in the Medicare population and are associated with very high mortality. Further study is warranted to understand the drivers of the increased prevalence of advanced liver disease for earlier identification and treatment.
