Effect of clustered nursing on liver function indexes, nutrition, and emotional status of patients with severe liver failure.

Liver failure is a metabolic disorder caused by a variety of mixed factors. For such diseases, adopting cluster care can effectively improve the relevant symptoms of patients. To explore the nursing effect of nutritional nursing combined with clustered nursing for patients with severe liver failure. A total of 129 patients with severe liver failure were selected as retrospective study subjects. Nine cases were due to an end event, such as death. The other patients were divided into control group and observation group according to different nursing methods. Among them, the control group adopted nutrition nursing, and the observation group implemented cluster nursing on this basis. The differences of liver function, anxiety and depression score, gastrointestinal recovery, nutritional status, and sleep quality were compared between the 2 groups before and after nursing. After nursing, the total bilirubin, albumin, and aspartate aminotransferase of the observation group were significantly higher than those of the control group (P < .05). The nursing staff used Self-Rating Anxiety Scale and Self-Rating Depression Scale of the observation group, which were slightly lower than those of the control group. The difference was statistically significant after testing (P < .05). After nursing, the observation group's upper arm circumference, brachial tri-scalp fold thickness, and hemoglobin were better than those of the control group. Statistics showed that the difference was statistically significant (P < .05). The depth of sleep, time to fall asleep, number of awakenings, time to fall asleep after awakening, overall sleep quality, and intensive care unit environmental noise intensity in the Richards-Campbell Sleep Questionnaire sleep scale after nursing in the 2 groups were significantly higher than those before nursing, and the scores of the observation group were significantly lower than those in the observation group. In the control group, this difference was statistically significant (P < .05). Nutritional nursing combined with clustered nursing can effectively promote the recovery of gastrointestinal function in patients with severe liver failure.

Prognostic role of albumin-bilirubin (ALBI) score and Child-Pugh classification in patients with advanced hepatocellular carcinoma under systemic treatment.

Hepatocellular carcinoma (HCC) is a lethal malignancy associated with cirrhosis and liver dysfunction. The aim of this study is to characterize a cohort of patients with advanced HCC according to liver function-related variables and evaluate the prognostic significance of Child-Pugh (CP) and albumin-bilirubin (ALBI) scores. A database of 406 HCC patients treated between 2009 and 2023 was retrospectively evaluated. Clinical and laboratory parameters were collected to classify patients into ALBI and CP scores. Survival was estimated using the Kaplan-Meier method and multivariate models were used to evaluate prognosis prediction. In this cohort, 337 (83%) patients were classified as CP-A, while 69 (17%) as CP-B. Additionally, according to ALBI score, 159 (39.2%) individuals were categorised as ALBI-1, 233 (57.4%) as ALBI-2 and 14 (3.4%) as ALBI-3. A statistically significant association between both classifications was observed (p < 0.001). CP and ALBI scores were independently associated with prognosis (Hazard ratio = 2.93 and 1.66, respectively), with better survival for patients with CP-A (versus B) and ALBI-1 (versus -2 and -3). ALBI score showed better predictive performance versus CP (c Harrell´s C index = 0.65 versus 0.62; p = 0.008) and ALBI evolution during the first month of treatment was associated with overall survival. Additionally, ALBI score was able to define distinct prognostic subgroups within CP-A patients. In conclusion, liver function scores, such as ALBI and CP, have a clinically relevant prognostic role in patients with advanced HCC under systemic treatment. ALBI score is a more granular scoring scale than CP, and enables a more precise evaluation of patients with CP-A.

Construction and validation of a preoperative prognostic model integrating the novel aspartate aminotransferase-albumin score for hepatocellular carcinoma patients undergoing liver resection.

Patients undergoing liver resection for hepatocellular carcinoma (HCC) often possess good liver reserve, which may limit the prognostic effectiveness of existing liver function scores. This study aimed to develop a novel liver function score and a preoperative prognostic model specifically for HCC resection patients. Eight hundred twenty-seven HCC patients undergoing initial liver resection were segregated into training and validation cohorts in a 6:4 ratio. Cox regression analysis was employed to identify significant parameters influencing overall survival. The efficacy of the liver function score and prognostic model was evaluated using metrics such as the area under the receiver operating characteristic curve. Aspartate aminotransferase (AST) and albumin emerged as significant prognostic indicators. The AST-albumin (ASAL) score, calculated as exp [AST (IU/L) × 0.005 - albumin (g/dL) × 1.043] × 100, outperformed existing scores such as Child-Turcotte-Pugh, albumin-bilirubin, platelet-albumin, and AST-platelet ratio index in both training and validation cohorts. Additionally, a scoring model that combined the ASAL score with alpha-fetoprotein and the up-to-seven criterion exhibited superior discriminatory capabilities compared to the American Joint Committee on Cancer tumor, node, metastasis stage, and Barcelona Clinic Liver Cancer stage. The proposed prognostic model that integrates the novel ASAL score offers promising prognostic potential for HCC patients undergoing liver resection.

A pilot study of safety and efficacy comparison of low molecular heparin calcium sequential oral anticoagulants in the treatment of cirrhotic portal vein thrombosis.

The objective of this study is to compare and assess the efficacy and safety of low-molecular-weight heparin calcium (LMWH-Ca), followed by either warfarin or rivaroxaban, as treatment options for portal vein thrombosis (PVT) in patients with cirrhosis. In this pilot study, cirrhotic (with liver function score of Child-Pugh A) patients diagnosed with PVT who were not on anticoagulant therapy received 2 weeks of subcutaneous injections of LMWH-Ca. They were then randomized to either warfarin (a full course of oral warfarin for 6 months) or rivaroxaban (a full course of oral rivaroxaban for 2 months), with 30 cases in each group. After a treatment period of up to 6 months, a comparative analysis was performed to assess the efficacy and safety of both groups. Volumetric changes in PVT were monitored dynamically using enhanced computed tomography scans before treatment at week 2 and month 6. There were no statistically significant differences in the clinical characteristics of the patients between the two groups. Rivaroxaban treatment reduced PVT median volume from 1.83 cm3 at week 2 to 0.0 cm3 at month 6 and prevented the worsening of PVT after 6 months of treatment with LMWH-Ca (P < 0.001). On the other hand, warfarin treatment increased PVT median volume from 1.95 cm3 at week 2 to 3.78 cm3 at month 6 (P = 0.002). None of the 30 patients in the rivaroxaban group had clinically significant gastrointestinal bleeding, while 2 of the 30 patients (7%) in the warfarin group had gastrointestinal bleeding (P = 0.317). Rivaroxaban followed by LMWH-Ca is an effective anticoagulant treatment strategy for PVT in cirrhosis.

Construction and Validation of a Novel Nomogram Predicting Recurrence in Alpha-Fetoprotein-Negative Hepatocellular Carcinoma Post-Surgery Using an Innovative Liver Function-Nutrition-Inflammation-Immune (LFNII) Score: A Bicentric Investigation.

We developed a nomogram based on the liver function, nutrition, inflammation, and immunity (LFNII) score to predict recurrence-free survival (RFS) post-resection in patients with hepatocellular carcinoma (HCC) exhibiting alpha-fetoprotein (AFP) negativity (AFP ≤20 ng/mL). Clinical data of 661 patients diagnosed with alpha-fetoprotein-negative hepatocellular carcinoma (AFP-NHCC) who underwent surgical resection at two medical centers between 2012 and 2021 were collected. A total of 462 and 199 patients served as the training and validation sets, respectively. Pre-operative blood markers were collected and analyzed for LFNII. The LFNII score was formulated using the least absolute shrinkage and selection operator Cox regression model. A nomogram model was developed using the training set to incorporate other relevant clinicopathological indicators and predict postoperative recurrence. Model discrimination was assessed using the receiver operating characteristic curve, calibration was evaluated using a calibration curve, and clinical applicability was assessed using clinical decision curve analysis. A comparison with liver cancer staging was performed using the nomogram model. Finally, a cohort study was conducted to validate our findings. We derived the LFNII scores from nine indicators. Elevated LFNII scores correlated with unfavorable clinicopathological features. The LFNII score area under the curve revealed superior predictive efficacy at 1-, 2-, and 5-year RFS intervals, with values of 0.675, 0.658, and 0.633, respectively. Multivariate Cox analysis revealed that a high LFNII score independently increased RFS risk in patients with AFP-NHCC. The C-index of the LFNII-nomogram model was 0.686 (95% confidence interval [CI], 0.651-0.721). The nomogram model's clinical application value surpassed that of standard HCC staging systems. The LFNII score-derived nomogram effectively predicted the RFS of patients with AFP-NHCC after curative resection.

Time variation of high-risk groups for liver function deteriorations within fluctuating long-term liver function after hepatic radiotherapy in patients with hepatocellular carcinoma

PurposeThe purpose of this study is to find essential risk factors associated with liver function (LF) deteriorations within fluctuating long-term LF and their time-varying effects in patients with hepatocellular carcinoma (HCC) receiving hepatic radiotherapy and to identify high-risk groups for adverse LF deteriorations and their changes over time in facilitating the prevention of hepatic decompensation and the improvement of survival.Materials and methodsA total of 133 HCC patients treated by hepatic radiotherapy were enrolled. A study design was conducted to convert posttreatment long-term LF with fluctuating levels over time to recurrent LF events using defined upgrades in a grading scale. The hazard ratios (HR) of pretreatment biochemical, demographic, clinical, and dosimetric factors in developing posttreatment LF events were estimated using the Cox model. Methodologies of the counting process approach, robust variance estimation, goodness-of-fit testing based on the Schoenfeld residuals, and time-dependent covariates in survival analysis were employed to handle the correlation within subjects and evaluate the time-varying effects during long-term follow-up.ResultsBaseline LF score before radiotherapy and gender were significant factors. Initial HR in developing LF events was 1.17 (95% CI 1.11–1.23; P < 0.001) for each increase of baseline LF score and kept almost constant over time (HR, 1.00; 95% CI 1.00–1.01; P = 0.065). However, no difference was observed regarding initial hazards for gender (HR, 1.00; 95% CI 0.64–1.56; P = 0.994), but the hazard for women got higher monthly over time compared with men (HR, 1.04; 95% CI 1.01–1.07; P = 0.006).ConclusionsHigh-risk groups for adverse LF deteriorations after hepatic radiotherapy may change over time. Patients with poor baseline LF are vulnerable from the beginning. Women require prevention strategies and careful monitoring for deteriorations at a later stage.

RNA-Sequencing Analysis and Expression of Lymphocyte-Specific Protein Tyrosine Kinase, Linker for Activation of T Cells, and 70-kDa T-Cell Receptor Zeta-Chain Associated Protein Kinase in Rat Liver Transplant Rejection.

The prevention and treatment of liver transplant rejection remain challenging. We investigated the pathophysiological mechanisms of liver transplant rejection in rats and screened candidate genes to determine their degree of rejection response for possible development of potential therapeutic targets. Brown Norway-Brown Norway transplant tolerant models and Lewis-Brown Norway transplant rejection models were established. We collected liver tissue and venous blood at 7 days posttransplant for hematoxylin and eosin staining and RNA sequencing analysis, respectively. We conducted differential expression gene analysis, KEGG and GO enrichment analysis. We performed immunohistochemistry to detect highly expressed immunerelated proteins, including lymphocyte-specific protein tyrosine kinase, linker for activation of T cells, and 70-kDa T-cell receptor zeta-chain-associated protein kinase. Significant differences were found in liver function and Banff scores between rejection and tolerant groups, indicating the successful establishment of liver transplant models. RNA-sequencing screened 7521 differentially expressed genes, with 3355 upregulated and 3058 downregulated. KEGG analysis of upregulated genes showed that 8 of the top 20 enrichment pathways were associated with immune system processes and 5 were related to immune system diseases. Among these immune pathways, 289 genes were upregulated; of these, 147 genes were removed after comparison with the IMMPORT database, of which 97 genes were significantly changed. Our GO analysis showed upregulated genes mainly participating in immune response processes, with downregulated genes mainly participating in metabolic processes. Real-time polymerase chain reaction and immunohistochemistry verified expression of the immune-related proteins, consistent with RNAsequencing results, which were mainly expressed in inflammatory cells in sinus and portal vein. Immune-related genes were found to be associated with liver transplant rejection. The 3 immune-related genes that we analyzed may play a role in liver transplant rejection and can possibly serve as candidate markers for monitoring the degree of liver transplant rejection.

Efficacy and safety of tenofovir disoproxil fumarate versus entecavir in the treatment of acute-on-chronic liver failure with hepatitis B: a systematic review and meta-analysis.

Oral nucleoside (acid) analogues (NAs) are recommended for patients with acute-on-chronic liver failure (ACLF) associated with hepatitis B virus (HBV-ACLF). The efficacy and safety of tenofovir (TDF) and entecavir (ETV) in these patients remain unclear. A comprehensive literature search in PubMed, Web of Science, The Cochrane Library, and Embase database was conducted to select studies published before December 2022 on TDF or ETV for HBV-ACLF. The primary outcomes were survival rates at 4, 12, and 48 weeks. Secondary outcomes were virologic and biochemical responses, serum antigen conversion, liver function score, and safety. Four prospective and one retrospective cohort studies were selected. The overall analysis showed comparable survival rates at 4, 12, and 48 weeks for all patients receiving TDF or ETV (4-week: RR = 1.17, 95% CI: 0.90-1.51, p = 0.24; 12-week: RR = 1.00, 95% CI: 0.88-1.13, p = 0.94; 48-week: RR = 0.96, 95% CI: 0.58-1.57, p = 0.86). Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease (MELD) score at 12 weeks were comparable in both groups but lower than baseline (CTP: SMD = -0.75, 95% CI:-2.81-1.30, p = 0.47; MELD: SMD = -1.10, 95% CI:-2.29-0.08, p = 0.07). At 48 weeks, estimated glomerular filtration rate (eGFR) levels were found to decrease to different degrees from baseline in both the TDF and ETV groups, and the decrease was greater in the TDF group than in the ETV group. No significant differences were found in biochemical, virologic response, and serum antigen conversion between the two groups during the observation period. TDF treatment of HBV-ACLF is similar to ETV in improving survival, liver function, and virologic response but the effects on renal function in two groups in the long term remain unclear. More and larger long-term clinical trials are required to confirm these findings.

Survival Outcome Analysis of Stereotactic Body Radiotherapy and Immunotherapy (SBRT-IO) versus SBRT-Alone in Unresectable Hepatocellular Carcinoma

Introduction: While combination of stereotactic body radiotherapy (SBRT) and immunotherapy are promising, their efficacy and safety have not been compared with SBRT-alone in patients with unresectable hepatocellular carcinoma (HCC). Methods: This retrospective study included 100 patients with nonmetastatic, unresectable HCC in two hospitals. Eligible patients had tumor nodules ≤3 and Child-Pugh liver function score of A5 to B7. Seventy patients received SBRT-alone, and 30 patients underwent combined SBRT and immunotherapy (SBRT-IO). Overall survival (OS), time to progression (TTP), overall response rate (ORR), and toxicity were analyzed. We adjusted for the potential confounding factors using propensity score matching. Results: The median tumor size was 7.3 cm (range, 2.6–18 cm). Twenty-five (25%) of patients had vascular invasion. Before propensity score matching, the 1-year and 3-year OS rate was 89.9% and 59.8% in the SBRT-IO group and 75.7% and 42.3% in SBRT-alone group (p = 0.039). After propensity score matching (1:2), 25 and 50 patients were selected from the SBRT-IO and SBRT-alone group. The 1-year and 3-year OS was 92.0% and 63.9% in the SBRT-IO group versus 74.0% and 43.3% in the SBRT-alone group (p = 0.034). The 1-year and 3-year TTP was better in SBRT-IO group (1-year: 68.9% vs. 58.9% and 3-year: 61.3% vs. 32.5%, p = 0.057). The ORR of 88% (complete response [CR]: 56%, partial response [PR]: 22%) in SBRT-IO arm was significantly better than 50% (CR: 20%, PR: 30%) in the SBRT-alone arm (p = 0.006). Three patients (12%) developed ≥grade 3 immune-related treatment adverse events (n = 2 hepatitis, n = 1 dermatitis) leading to permanent treatment discontinuation. Conclusion: Adding immunotherapy to SBRT resulted in better survival with manageable toxicities. Prospective randomized trial is warranted.

Volume-Assisted Estimation of Remnant Liver Function Based on Gd-EOB-DTPA Enhanced MR Relaxometry: A Prospective Observational Trial.

In the context of liver surgery, predicting postoperative liver dysfunction is essential. This study explored the potential of preoperative liver function assessment by MRI for predicting postoperative liver dysfunction and compared these results with the established indocyanine green (ICG) clearance test. This prospective study included patients undergoing liver resection with preoperative MRI planning. Liver function was quantified using T1 relaxometry and correlated with established liver function scores. The analysis revealed an improved model for predicting postoperative liver dysfunction, exhibiting an accuracy (ACC) of 0.79, surpassing the 0.70 of the preoperative ICG test, alongside a higher area under the curve (0.75). Notably, the proposed model also successfully predicted all cases of liver failure and showed potential in predicting liver synthesis dysfunction (ACC 0.78). This model showed promise in patient survival rates with a Hazard ratio of 0.87, underscoring its potential as a valuable tool for preoperative evaluation. The findings imply that MRI-based assessment of liver function can provide significant benefits in the early identification and management of patients at risk for postoperative liver dysfunction.

The Liver Function Score – “ALBI” Sets Apart Melioidosis, Scrub Typhus from Viral Hepatitis, Tuberculosis, Enteric Fever in a III-II Grade Score: Useful in Machine Learning and AI

ALBI (Albumin-Bilirubin) score is routinely used in grading liver function of hepatocarcinoma and hepatitis patients. In this purposive review, the published values of serum albumin, bilirubin in Viral hepatitis, Tuberculosis, Scrub typhus, Enteric fever has been compared with that of melioidosis. Since PubMed yielded zero searches with key words “albumin, bilirubin, melioidosis”, it was searched in Google Scholar, a better retrievable search engine. This yielded 46 relevant articles with 53 ALBI scores for Melioidosis. An equivalent search to retrieve 53 ALBI scores was made in Google Scholar for other confounding diseases of Melioidosis with search words “albumin, bilirubin, hepatitis” “albumin, bilirubin, tuberculosis”, “albumin, bilirubin, scrub typhus”, “albumin, bilirubin, enteric fever”. This raw data was deposited in Harvard dataverse (https://doi.org/10.7910/DVN/QEW20J) and subsequent analysis done is documented in this article. This placed Melioidosis patients and Scrub typhus patients to be on an average grade III ALBI and the patients of Viral hepatitis, Tuberculosis, and Enteric fever in grade II ALBI.&#x0D; GRAPHICAL ABSTRACT&#x0D;

Using AI and Gd-EOB-DTPA-enhanced MR imaging to assess liver function, comparing the MELIF score with the ALBI score

Monitoring disease progression is particularly important for determining the optimal treatment strategy in patients with liver disease. Especially for patients with diseases that have a reversible course, there is a lack of suitable tools for monitoring liver function. The development and establishment of such tools is very important, especially in view of the expected increase in such diseases in the future. Image-based liver function parameters, such as the T1 relaxometry-based MELIF score, are ideally suited for this purpose. The determination of this new liver function score is fully automated by software developed with AI technology. In this study, the MELIF score is compared with the widely used ALBI score. The ALBI score was used as a benchmark, as it has been shown to better capture the progression of less severe liver disease than the MELD and Child‒Pugh scores. In this study, we retrospectively determined the ALBI and MELIF scores for 150 patients, compared these scores with the corresponding MELD and Child‒Pugh scores (Pearson correlation), and examined the ability of these scores to discriminate between good and impaired liver function (AUC: MELIF 0.8; ALBI 0.77) and to distinguish between patients with and without cirrhosis (AUC: MELIF 0.83, ALBI 0.79). The MELIF score performed more favourably than the ALBI score and may also be suitable for monitoring mild disease progression. Thus, the MELIF score is promising for closing the gap in the available early-stage liver disease monitoring tools (i.e., identification of liver disease at a potentially reversible stage before chronic liver disease develops).

Modified integrated tumor burden, liver function, systemic inflammation, and tumor biology score to predict long-term outcomes after resection for hepatocellular carcinoma

BackgroundA preoperative predictive score for hepatocellular carcinoma (HCC) can help stratify patients who undergo resection relative to long-term outcomes and tailor treatment strategies. MethodsPatients who underwent curative-intent hepatectomy for HCC between 2000 and 2020 were identified from an international multi-institutional database. A risk score (mFIBA) was developed using an Eastern cohort and then validated using a Western cohort. ResultsAmong 957 patients, 443 and 514 patients were included from the Eastern and Western cohorts, respectively. On multivariable analysis, alpha-feto protein (HR1.97, 95%CI 1.42–2.72), neutrophil-to-lymphocyte ratio (HR1.74, 95%CI 1.28–2.38), albumin-bilirubin grade (HR1.66, 95%CI 1.21–2.28), and imaging tumor burden score (HR1.25, 95%CI 1.12–1.40) were associated with OS. The c-index in the Eastern test and Western validation cohorts were 0.69 and 0.67, respectively. Notably, mFIBA score outperformed previous HCC staging systems. 5-year OS incrementally decreased with an increase in mFIBA. On multivariable Cox regression analysis, the mFIBA score was associated with worse OS (HR1.18, 95%CI 1.13–1.23) and higher risk of recurrence (HR1.16, 95%CI 1.11–1.20). An easy-to-use calculator of the mFIBA score was made available online (https://yutaka-endo.shinyapps.io/mFIBA_score/). DiscussionThe online mFIBA calculator may help surgeons with clinical decision-making to individualize perioperative treatment strategies for patients undergoing resection of HCC.

Potential candidates for liver resection in liver-confined advanced HCC: a Chinese multicenter observational study.

Advanced hepatocellular carcinoma (HCC) is characterized as symptomatic tumors [performance status (PS) score of 1-2], vascular invasion and extrahepatic spread, but patients with PS1 alone may be eliminated from this stage. Although liver resection is used for liver-confined HCC, its role in patients with PS1 alone remains controversial. Therefore, we aimed to explore its application in such patients and identify potential candidates. Eligible liver-confined HCC patients undergoing liver resection were retrospectively screened in 15 Chinese tertiary hospitals, with limited tumor burden, liver function and PS scores. Cox-regression survival analysis was used to investigate the prognostic factors and develop a risk-scoring system, according to which patients were substratified using fitting curves and the predictive values of PS were explored in each stratification. From January 2010 to October 2021, 1535 consecutive patients were selected. In the whole cohort, PS, AFP, tumor size and albumin were correlated with survival (adjusted P<0.05), based on which risk scores of every patient were calculated and ranged from 0 to 18. Fitting curve analysis demonstrated that the prognostic abilities of PS varied with risk scores and that the patients should be divided into three risk stratifications. Importantly, in the low-risk stratification, PS lost its prognostic value, and patients with PS1 alone achieved a satisfactory 5-year survival rate of 78.0%, which was comparable with that PS0 patients (84.6%). Selected patients with PS1 alone and an ideal baseline condition may benefit from liver resection and may migrate forward to BCLC stage A.

Boosted-Dose Yttrium-90 Radiation Segmentectomy or Lobectomy for Hepatocellular Carcinoma Refractory to Prior Transarterial Embolization or Chemoembolization: A Single Institution Retrospective Case Series.

To assess the tumor response rates and liver toxicity of boosted-dose transarterial radioembolization (TARE) for treatment of hepatocellular carcinoma (HCC) refractory to previous transarterial embolization (TAE) and/or chemoembolization (TACE). All patients were identified who had HCC treated between 2017 and 2020 that had been refractory to prior TAE or TACE, then treated with boosted-dose segmental or lobar TARE. Tumor response was assessed by multiphasic CT or MRI using localized mRECIST imaging criteria and serological alpha-fetoprotein levels at three and six months after TARE, if available. Liver toxicity was evaluated using serial serological liver function tests, platelet counts, and clinical Child-Pugh and MELD scores. Twenty-four patients met inclusion criteria. Mean age was 68.7years (54-89); 8 were females. Three (12.5%) patients had Barcelona Clinical Liver Cancer stage A, 4 (16.7%) stage B, and 17 (70.8%) stage C disease. Three months after TARE, 52% of patients had a complete response and 33% had a partial response. Mean AFP decreased from 33.2ng/mL at baseline to 17ng/mL at 3months (p = 0.782). The median MELD-Na score increased from 11 at baseline to 16 at 6months post-TARE (p = 0.044); the mean Child-Pugh score rose from 5 at baseline to 6 at 3months post-TARE (p < 0.01). Boosted-dose TARE resulted in statistically significant favorable tumor responses by imaging criteria in 85% of patients previously refractory to TAE or TACE. TARE resulted in transient but acceptable deterioration of liver function and clinical scores.

Endovascular therapy accompanied by spontaneous portosystemic shunts for overt hepatic encephalopathy

Objective: To preliminarily evaluate the safety and efficacy of shunt-related interventional therapy accompanied with spontaneous portosystemic shunts (SPSS) in patients with hepatic encephalopathy (HE). Methods: Case data on six patients who underwent interventional therapy accompanied by SPSS for HE from January 2017 to March 2021 were collected to evaluate the efficacy and postoperative complications. Results: All six patients underwent SPSS. Four patients had hepatitis B cirrhosis; one had alcoholic cirrhosis; and one had hepatic arterioportal fistula-induced portal hypertension. Child-Pugh liver function scores were C and B in three and three cases, respectively. The SPSS type was gastrorenal shunt in two cases; portal-thoracic-azygos venous in two cases; portal-umbilical-iliac venous in one case; and portal-splenic venous - inferior vena cava in one case. Two of them had previously had a transjugular intrahepatic portosystemic shunt (TIPS), and there were SPSS prior to TIPS. Five cases (5/6) successfully underwent shunt embolization, and one case (1/6) underwent stent implantation for flow restriction (portal-umbilical-iliac vein). The technical success rate was 100%. HE did not recur during hospitalization or the three-month follow-up period. However, one case had a recurrence of HE within a year after surgery and was treated symptomatically, while another experienced gastrointestinal bleeding a year after surgery.. Conclusion: SPSS embolization or flow restriction is effective and safe for improving HE patients' symptoms.

Effects of body composition and liver function after long-term pemafibrate treatment on dyslipidemia-associated non-alcoholic fatty liver disease.

Owing to the association between non-alcoholic fatty liver disease (NAFLD) and dyslipidemia, there is a need for new treatment strategies to manage both conditions concomitantly. Our aim in this study was to evaluate the effectiveness of pemafibrate in alleviating dyslipidemia-associated NAFLD, including the evaluation of its effects on liver function and body composition. The study sample included 67 patients with dyslipidemia-associated NAFLD (29 males, mean age 65.7 years [range, 58.4-73.7]) who were administered pemafibrate continuously for a period of at least 12 months, between June 2019 and January 2022. Outcomes were the change in body composition indices (visceral adipose tissue index - VATI, subcutaneous adipose tissue index - SATI, and skeletal muscle index - SMI), lipid biochemistry, and liver function, reserve, and fibrosis score, from baseline to the 12-month time point of pemafibrate treatment. Pemafibrate treatment improved liver function (alanine aminotransferase, aspartate aminotransferase, g-glutamyl transpeptidase, and alkaline phosphatase), and lipid biochemistry (triglycerides and total cholesterol). Improvements in ferritin and hepatic reserve (Mac-2 binding protein, albumin-to-bilirubin score, and NAFLD fibrosis score) were also observed, as well as a decrease in SATI. Pemafibrate improved dyslipidemia, liver function, and hepatic reserve. The positive effects of pemafibrate on body composition likely contributed to the improvements in liver function. Longer-term treatment may be necessary to influence VATI and thus to further evaluate the relationship between improved body composition and NAFLD with pemafibrate treatment.

Portal hypertension increases the risk of hepatic decompensation after 90Yttrium radioembolization in patients with hepatocellular carcinoma: a cohort study.

Transarterial radioembolization (TARE) is increasingly used in patients with hepatocellular carcinoma (HCC). This treatment can induce or impair portal hypertension, leading to hepatic decompensation. TARE also promotes changes in liver and spleen volumes that may modify therapeutic decisions and outcomes after therapy. We aimed to investigate the impact of TARE on the incidence of decompensation events and its predictive factors. In all, 63 consecutive patients treated with TARE between February 2012 and December 2018 were retrospectively included. We assessed clinical (including Barcelona Clinic Liver Cancer stage, portal hypertension assessment, and liver decompensation), laboratory parameters, and liver and spleen volumes before and 6 and 12 weeks after treatment. A multivariate analysis was performed. In total, 18 out of 63 (28.6%) patients had liver decompensation (ascites, variceal bleeding, jaundice, or encephalopathy) within the first 3 months after therapy, not associated with tumor progression. Clinically significant portal hypertension (CSPH) and bilobar treatment independently predicted the development of liver decompensation after TARE. A significant volume increase in the non-treated hemi-liver was observed only in patients with unilobar treatment (median volume increase of 20.2% in patients with right lobe TARE; p = 0.007), especially in those without CSPH. Spleen volume also increased after TARE (median volume increase of 16.1%; p = 0.0001) and was associated with worsening liver function scores and decreased platelet count. Bilobar TARE and CSPH may be associated with an increased risk of liver decompensation in patients with intermediate or advanced HCC. A careful assessment considering these variables before therapy may optimize candidate selection and improve treatment planning.

An Integrated Liver Function, Systemic Inflammation, and Tumor Characteristic Score Predicts Prognosis in Hepatocellular Carcinoma After Curative Resection.

Several scoring systems are currently used to predict prognosis of hepatocellular carcinoma (HCC), but none of them integrates liver function, systemic inflammation, and tumor characteristics in a unified model. The current study aimed to develop and validate a novel prognostic score that integrates liver function, systemic inflammation, and tumor characteristics in a unified model to predict the prognosis of HCC after curative resection. Patients with HCC who underwent curative liver resection were included in a training set (n = 1027). Multivariate Cox regression was performed to determine the risk factors for a poor prognosis. A prognostic score was developed by assigning points for risk factors in proportion to beta coefficients in a Cox multivariable model. Predictive performance and distinction ability of the prognostic score were further evaluated in two independent validation cohorts treated with either curative resection (n = 281) or transarterial chemoembolization (TACE) (n = 404) and compared with 16 other models. The prognostic predictive system, named the function-inflammation-burden-alpha-fetoprotein (FIBA) score, was derived by assigning points for six independent predictors including albumin, total bilirubin, lymphocyte count, diameter of the largest tumor, number of tumors, and alpha-fetoprotein (AFP). The FIBA score showed an outperformed predictive value compared with other systems in both training and validation cohorts by giving the highest C-index, likelihood ratio chi-square values, and Wald test values as well as the lowest Akaike information criterion. The FIBA score can be used to stratify HCC patients treated with curative resection. Meanwhile, the FIBA score performs well against other prognostic scoring systems and is potentially broadly applicable to a TACE-treated patient cohort.

Sequential transarterial chemoembolisation and stereotactic body radiotherapy followed by immunotherapy as conversion therapy for patients with locally advanced, unresectable hepatocellular carcinoma (START-FIT): a single-arm, phase 2 trial

The synergy between locoregional therapies and immune checkpoint inhibitors has not been investigated as conversion therapy for unresectable hepatocellular carcinoma. We aimed to investigate the activity of sequential transarterial chemoembolisation (TACE) and stereotactic body radiotherapy followed by avelumab (an anti-PD-L1 drug) for locally advanced, unresectable hepatocellular carcinoma. START-FIT was a single-arm, phase 2 trial in patients with locally advanced hepatocellular carcinoma who were not suitable for curative treatment, conducted in two hospitals in Hong Kong and one in Shenzhen, China. Eligible patients were those aged 18 years or older with an Eastern Cooperative Oncology Group performance status 0-1, Child-Pugh liver function score A5 to B7, tumour size of at least 5 cm, a maximum of three tumour lesions, and adequate hepatic, renal, and bone marrow function. Participants received TACE on day 1, followed by stereotactic body radiotherapy (27·5-40·0 Gy in five fractions) at day 28. Avelumab (10 mg/kg) was administered 14 days following stereotactic body radiotherapy and every 2 weeks thereafter. The primary endpoint was the proportion of patients deemed amenable to curative treatment, defined as those who had a sustained complete or partial treatment response for at least 2 months and if curative treatment could be performed (ie, resection, radiofrequency ablation, or transplantation), analysed by intention to treat. Safety was also analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT03817736) and has been completed. Between March 18, 2019, and Jan 27, 2021, 33 patients (32 [97%] men and one [3%] woman) were enrolled. The median sum of the largest diameters of lesions was 15·1 cm (IQR 8·3-14·9). 21 (64%) patients had macrovascular invasion (hepatic vein [n=13], branched portal vein [n=3], or both [n=5]). Median follow-up was 17·2 months (IQR 7·8-25·8). 18 (55%) patients were deemed amenable to curative treatment: four (12%) of 33 patients had curative treatment (resection [n=2] or radiofrequency ablation [n=2]), and 14 (42%) had a radiological complete response and opted for close surveillance. 11 (33%) of 33 patients had treatment-related adverse events that were grade 3 or worse. The most common treatment-related grade 3 or worse adverse event was transient increase in alanine aminotransferase or aspartate aminotransferase (five [15%]) after TACE. Five (15%) patients developed immune-related adverse events of grade 3 or worse (three had hepatitis, two had dermatitis). To our knowledge, this is the first prospective trial using the combination of immunotherapy and locoregional treatment as conversion therapy for locally advanced unresectable hepatocellular carcinoma, with promising results. Future randomised trials with larger cohorts of patients are warranted. Merck.
