Some adipose-related parameters exhibit distinct prognostic value in patients with cirrhosis. However, the magnitude and direction of the association between individual adipose parameter and mortality in patients with cirrhosis are unclear.

This study aimed to evaluate the association between individual adipose parameter and mortality in patients with cirrhosis using the meta-analysis method.

The PubMed, Embase, Web of Science, China Biological Medicine, WanFang, and China National Knowledge Infrastructure databases were searched from inception through December 15, 2023, to identify eligible studies. The impact of each adipose parameter on mortality was assessed by the pooled unadjusted or adjusted hazard ratio (HR) with 95% confidence intervals (CIs) using the random effects model.

A total of 33 studies involving 9626 patients were included in our analysis, with 11 adipose parameters evaluated. The pooled prevalence of sarcopenic obesity (SO) and myosteatosis in patients with cirrhosis was 15.5% and 34.4%, respectively. In adjusted analysis, each unit increase in subcutaneous adipose tissue index (SATI) (HR: 0.99, 95% CI: 0.98-1.00) or muscle attenuation (MA) (HR: 0.94, 95% CI: 0.90-0.98) and each unit decrease in visceral-to-subcutaneous adipose tissue ratio (VSR) (HR: 1.92, 95% CI: 1.45-2.54) showed an independent association with a decreased risk of mortality. However, concurrent myosteatosis (HR: 1.88, 95% CI: 1.48-2.40) or SO (HR: 2.77, 95% CI: 1.95-3.93) significantly increased the risk of mortality in patients with cirrhosis.

Decreased SATI or MA, increased VSR, and concurrent myosteatosis or SO were independently associated with a higher risk of mortality in patients with cirrhosis.

Sarcopenia is a prevalent condition in tumor patients and can potentially impact the prognosis of tumor treatment. This retrospective study aimed to evaluate the correlations between sarcopenia and the prognosis of patients with unresectable colorectal liver metastases (CRLM) received drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE) therapy. From December 2018 to December 2023, unresectable CRLM patients who had already received second-line therapy from the Wuhan Union Hospital were involved in our study. Skeletal muscle mass was evaluated on CT at the L3 vertebra, and the optimal cut-off point for skeletal muscle index classification was determined using x-tile software. Overall survival (OS) and progression-free survival (PFS) were estimated using Kaplan-Meier analysis and Cox regression analysis. Seventy-one patients were included in the study, 34 with sarcopenia (sarcopenia group) and 37 without sarcopenia (non-sarcopenia group), respectively. The median PFS and OS was elevated in the non-sarcopenia group compared with the sarcopenia group (6.1 months versus 4.3 months, p = 0.012; 14.8 months versus 10.2 months, p < 0.001). The multivariate Cox regression analysis revealed that sarcopenia, extrahepatic metastases, and neutrophil-to-lymphocyte ratio (NLR) ≥ 5 were identified as independent risk factors for both PFS and OS. The advantages of non-sarcopenia in terms of OS were consistent across all subgroups examined. Additionally, the sarcopenia group exhibited a higher incidence of vomiting/nausea, fatigue, and abdominal pain following the DEB-TACE operation compared to the non-sarcopenia group. Sarcopenia demonstrated a substantial predictive value for both PFS and OS in unresectable CRLM patients who underwent DEB-TACE treatments. Besides, NLR > 5 and extrahepatic metastases were independent risk factors linked to a poorer prognosis. Furthermore, patients with sarcopenia may face an increased likelihood of experiencing adverse events following DEB-TACE treatments.

Acute-on-chronic liver failure (ACLF) is a life-threatening hepatic syndrome. Therefore, this study aimed to develop a comprehensive model combining extracellular liver volume derived from spectral CT (ECVIC-liver) and sarcopenia, for the early prediction of short-term (90-day) disease progression in ACLF.

A retrospective cohort of 126 ACLF patients who underwent hepatic spectral CT scans was included. According to the Asia-Pacific Association for the Study of the Liver (APASL) criteria, patients were divided into the progression group (n = 70) and the stable group (n = 56). ECVIC-liver was measured on the equilibrium period (EP) images of spectral CT, and L3-SMI was measured on unenhanced CT images, with sarcopenia assessed. A comprehensive model was developed by combining independent predictors. Model performance was evaluated using receiver operating characteristic (ROC) curve analysis, calibration curves, and decision curve analysis (DCA).

In the univariate analysis, BMI, WBC, PLT, PTA, L3-SMI, IC-EP, Z-EP, K140-EP, NIC-EP, ECVIC-liver, and Sarcopenia demonstrated associations with disease progression status at 90 days in ACLF patients. In multivariate logistic regression, white blood cell count (WBC) (OR = 1.19, 95% CI: 1.02-1.40; P = 0.026), ECVIC-liver (OR = 1.27, 95% CI: 1.15-1.40; P < 0.001), sarcopenia (OR = 4.15, 95% CI: 1.43-12.01; P = 0.009), MELD-Na score (OR = 1.06, 95%CI: 1.01-1.13;P = 0.042), and CLIF-SOFA score (OR = 1.37, 95%CI:1.15-1.64; P<0.001) emerged as independent risk factors for ACLF progression. The combined model exhibited superior predictive performance (AUCs = 0.910, sensitivity = 80.4%, specificity = 90.0%, PPV = 0.865, NPV = 0.851) compared to CLIF-SOFA, MELD-Na, MELD and CTP scores(both P < 0.001). Calibration curves and DCA confirmed the high clinical utility of the combined model.

Patients without sarcopenia and/or with a lower ECVIC-liver have a better prognosis, and the integration of WBC, ECVIC-liver, Sarcopenia, CLIF-SOFA and MELD-Na scores in a composite model offers a concise and effective tool for predicting disease progression in ACLF patients.

A consensus has not yet been reached regarding the optimal timing for the combination of transjugular intrahepatic portosystemic shunt (TIPS) and partial splenic embolization (PSE) in patients with cirrhosis-related variceal bleeding and hypersplenism. This study aimed to compare the clinical outcomes of patients who underwent either an early or late combination of TIPS and PSE.

A total of 84 consecutive patients with cirrhosis-related variceal bleeding and hypersplenism who underwent TIPS and PSE between September 2016 and April 2023 were included in this retrospective multicenter study. These patients were subsequently divided into early combination (n = 36) and late combination (n = 48) groups based on the timing of the combination therapy.

Kaplan-Meier curves revealed a significant increase in cumulative survival in the late combination group, compared with that in the early combination group (log-rank P = 0.018). Additionally, the late combination group exhibited a lower cumulative incidence of overt hepatic encephalopathy (OHE), compared with the early combination group (log-rank P = 0.002). In Cox regression models, noninfarcted splenic volume (hazard ratio [HR] = 0.995, 95% confidence interval [CI] = 0.991-0.999, P = 0.044) and grouping (HR = 0.101, 95% CI = 0.011-0.921, P = 0.034) were identified as independent risk factors for mortality. Furthermore, the independent risk factors for OHE were serum albumin (ALB) level (P = 0.032) and grouping (P = 0.028).

The early combination of TIPS and PSE was associated with higher risks of death and OHE than the late combination.

To assess the relationship between clinical prognosis and changes of skeletal muscle mass for unresectable hepatocellular carcinoma (uHCC) patients who received transarterial chemoembolization (TACE) with molecular-targeted agents and immune checkpoint inhibitors (TACE-MTAs-ICIs).

From June 2019 to June 2023, a total of 92 uHCC patients who received TACE-MTAs-ICIs therapy were included. Skeletal muscle mass was assessed before and 6 months after treatment. Skeletal muscle index (SMI) is calculated as skeletal muscle area at the L3 vertebra divided by the square of height, then the change rate of SMI (ΔSMI) is calculated. Patients were stratified based on ΔSMI as muscle gain and non-muscle gain groups. Overall survival (OS) was compared between groups and prognostic factors for OS were analyzed. Progression-free survival (PFS) was also recorded.

The median OS in the muscle gain group was significantly longer than that in the non-muscle gain group (Not reach vs 25.2 months, P < 0.001). The median PFS did not reach significant between two groups (16.2 vs 9.1 months, P = 0.101). Multivariate analyses revealed that skeletal muscle gain (HR = 0.20; 95% CI, 0.06-0.68; P = 0.010) and Barcelona Clinic Liver Cancer stage (HR = 1.94; 95% CI, 1.02-3.69; P = 0.044) were independent prognostic factors for OS.

SMI increment appeared as a favorable predictor for these uHCC patients who received TACE-MTAs-ICIs therapy.

Elderly patients with advanced gastric cancer have poor prognoses. This study aims to develop a prediction model for long-term survival after radical surgery and to identify patients who may benefit from chemotherapy.

Data from 555 elderly patients with advanced gastric cancer admitted to two medical centers from 2009 to 2018 were retrospectively analyzed. Sarcopenia was combined with the Controlling Nutritional Status (CONUT) score to create a modified nutritional index (mCONUT). Cox regression analyses were used to develop a novel nomogram prediction model (mCNS) that combined mCONUT, pN, and tumor size, and its performance was further verified both internally and externally.

Multivariate Cox analysis revealed that tumor size, pN, and mCONUT were independent prognostic risk factors for overall survival (OS). The mCNS model showed good fit and high predictive value (AUC: training set 0.711; validation set 0.707), outperforming the pTNM model (p < 0.05). To further investigate the association between the model and adjuvant chemotherapy, we categorized the model into two risk groups: a high-risk group and a low-risk group. Further analysis revealed that, in the low-risk group, the OS and recurrence-free survival(RFS) for patients receiving adjuvant chemotherapy was significantly better than that of those who did not receive chemotherapy (p = 0.047,p = 0.019). In the high-risk group, this result was not observed (p = 0.120, p = 0.053).

The mCNS model has high predictive value in predicting long-term survival of elderly patients with advanced gastric cancer. Patients with mCNS-L were able to benefit from chemotherapy after laparoscopic radical gastrectomy.

Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.

To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.

This retrospective single-center study included 218 patients with AVB who underwent TIPS. The dataset was divided into training (70%) and testing (30%) sets. Critical features were identified using embedded methods and recursive feature elimination. Three ML algorithms-random forest, extreme gradient boosting, and logistic regression-were validated via 10-fold cross-validation. SHapley Additive exPlanations analysis was employed to interpret the model's predictions. Survival analysis was conducted using Kaplan-Meier curves and stepwise Cox regression analysis to compare overall survival (OS) between patients with and without OHE.

The median OS of the study cohort was 47.83 ± 22.95 months. Among the models evaluated, logistic regression demonstrated the highest performance with an area under the curve (AUC) of 0.825. Key predictors identified were Child-Pugh score, age, and portal vein thrombosis. Kaplan-Meier analysis revealed that patients without OHE had a significantly longer OS (P = 0.005). The 5-year survival rate was 78.4%, with an OHE incidence of 15.1%. Both actual OHE status and predicted OHE value were significant predictors in each Cox model, with model-predicted OHE achieving an AUC of 88.1 in survival prediction.

The ML model accurately predicts post-TIPS OHE and outperforms traditional models, supporting its use in improving outcomes in patients with AVB.

Trans-jugular intrahepatic portosystemic stent shunting (TIPSS) has been in use for many years with great results and many evolutions. The procedure essentially involves the insertion of a metal covert stent to create an Hepato-Hepatic portosystemic shunt. Over time, TIPSS has become the subject of many studies aimed at examining its clinical utility and evaluating the results of using TIPSS to manage complications related to portal hypertension. From the outset, this procedure has been met with hope and enthusiasm and give the chance to consider another possibility to treat the complications of portal hypertension without the use of surgery. Considering that TIPSS is an attractive alternative to shunt surgery because it does not require the use of general anesthesia or laparotomy, in fact this method is applicable to many patients with severe liver disease not suitable for it. TIPSS has been studied for the management of variceal bleeding, ascites, hepatic hydrothorax, hepatorenal syndrome, and other types of cirrhosis. However, some drawbacks of the TIPSS, such as shunt stenosis and hepatic encephalopathy, have also been reported in the literature. On the basis of the available evidence and the new epidemiological findings regarding liver disease, the following question may be posed: What is the place of TIPSS in current clinical practice?

To investigate the association between overt hepatic encephalopathy (OHE) and liver pathology after transjugular intrahepatic portosystemic shunt (TIPS) creation in cirrhotic patients. From July 2015 to April 2024, 73 patients from 4 hospitals in China who received TIPS creation and liver biopsy were retrospectively enrolled in this study. Based on whether OHE occurred within 3 months after TIPS creation, the patients were categorized into OHE (n = 29) and non-OHE (n = 44) groups. The liver pathology was assessed by hematoxylin-eosin (H&E), Sirius red staining, immunohistochemistry, and immunofluorescence. Liver pathology by H&E staining showed typical features of liver cirrhosis (including disordered structure and pseudolobule formation) in all the patients. No marked difference was observed in extracellular matrix (ECM) deposition between the OHE and non-OHE groups. However, the patients in the OHE group had a higher level of liver and systemic inflammation than in the non-OHE group. And there was a strong correction between intrahepatic macrophage infiltration and serum inflammatory indicators. Additionally, the OHE group had more liver neovascularization, which was consistent with liver inflammation. The emergence of OHE after TIPS creation is closely associated with liver pathology, especially in liver inflammation and angiogenesis, but not in ECM deposition.

The association between perioperative changes in the skeletal muscle index (SMI) and colorectal cancer (CRC) outcomes remains unclear. We aim to explore perioperative change patterns of SMI and evaluate their effects on long-term outcomes in CRC patients.

This retrospective cohort study included Stage I-III CRC patients who underwent curative resection between 2012 and 2019. SMI at the third lumbar vertebra level was calculated using computed tomography scans. Optimal cut-off values for SMI were defined separately for males and females and classified as high or low preoperatively and at 3, 6, 9 and 12 months postoperatively. SMI status was further categorized into different perioperative SMI change patterns: highpre-highpost, highpre-lowpost, lowpre-highpost and lowpre-lowpost. The association with recurrence-free survival (RFS) and overall survival (OS) was examined using Cox proportional hazards models.

A total of 2222 patients (median [interquartile range] age, 60.00 [51.00-68.00] years; 1302 (58.60%) men; 222 (9.99%) with preoperative low SMI) were evaluated. During a median follow-up of 60 months, 375 patients (16.88%) died, and 617 patients (27.77%) experienced a recurrence. Multivariate Cox model analysis showed that, compared to patients with highpre-highpost, those with highpre-lowpost (HR = 3.32, 95% CI: 1.60-6.51; HR = 2.54, 95% CI: 1.03-6.26; HR = 2.93, 95% CI: 1.19-7.19, all p < 0.05) had significantly worse RFS and OS (HR = 4.07, 95% CI: 1.55-10.69; HR = 4.78, 95% CI: 1.40-16.29; HR = 9.69, 95% CI: 2.53-37.05, all p < 0.05), at postoperative 6, 9 and 12 months, respectively. Patients with lowpre-lowpost were an independent prognostic factor for worse OS at postoperative 12 months (HR = 3.20, 95% CI: 1.06-9.71, p = 0.040). Patients with lowpre-highpost had similar risk of RFS compared to those with highpre-highpost at postoperative 3, 6 and 12 months (HR = 1.49, 95% CI: 0.75-2.98; HR = 1.05, 95% CI: 0.45-2.43; HR = 1.36, 95% CI: 0.31-6.06, all p > 0.05) and similar risk of OS at postoperative 3, 6, 9 and 12 months (all p > 0.05).

Patients with a high preoperative SMI that decline postoperatively have poor RFS and OS. Consistently low SMI also correlates with worse OS. Patients with low SMI but increased after resection are not an indicator of better prognosis. Routine measurement of postoperative, rather than preoperative, SMI is warranted. Patients with low SMI are at an increased risk for recurrence and death, especially within the first year after surgery.

Emerging evidence on cirrhosis suggests a close correlation between abnormality in body composition characteristics and poor prognosis. This study aimed to evaluate the impact of dynamic changes in body composition on the prognostic outcomes in patients with cirrhosis.

This retrospective analysis included 158 patients diagnosed as cirrhosis from January 2018 to August 2023. Skeletal muscle mass, muscle quality, visceral and subcutaneous adiposity were evaluated using computed tomography (CT) imaging at the third lumbar vertebra level. Competing risk model was performed four different body composition status (i.e., normal, only sarcopenia, only myosteatosis, and combined status) for liver-related mortality. We also explored the relationship between the dynamic change in body composition and long-term prognosis by applying Gray's test.

Of the 158 cirrhotic patients (mean [SD] age, 57.1 [12.6] years), sarcopenia was present in 85 (60.1 %) patients, while 22 (13.9 %) patients had sarcopenic obesity and 68 (43.0 %) had myosteatosis. Patients solely diagnosed with sarcopenia exhibited a higher mortality rate compared to those with normal body composition (Gray's test, P=0.006), while patients solely diagnosed with myosteatosis or with a combination of sarcopenia and myosteatosis did not reach statistical significance (Gray's test, P=0.076; P=0.140). Multivariable analysis also revealed that VSR (HR=1.10 [1.01∼1.20]; P=0.028), sarcopenia (HR=2.73 [1.20∼6.22], P=0.017) and myosteatosis (HR=2.39 [1.10∼5.18], P=0.028) were significant independent predictors of liver-related deaths. Otherwise, patients exhibiting aggravating body composition during follow-up period were associated with a significantly higher mortality risk compared to those with normal or remission body composition status (HR=7.63 [1.12∼51.14]; P=0.036).

Progressive alterations in body composition status appears to be associated with liver-related mortality in individuals with liver cirrhosis. Focusing on the management of skeletal muscle, along with visceral and subcutaneous adiposity, may contribute to improving the prognosis of cirrhotic patients.

The transjugular intrahepatic portosystemic shunt (TIPS) is an important technique for treating complications related to portal hypertension in patients with cirrhosis, and the number of publications in the TIPS field continues to rise.

To facilitate an understanding of the research status and hotspots in the field of TIPS using CiteSpace bibliometric analysis.

CiteSpace is a software that depicts the strength of relationships through graphics and connections with diverse functionalities and can be used to analyze the status and hotspots of areas of research. Articles on TIPS in the Web of Science Core Collection were retrieved, and CiteSpace software was used to visualize and analyze the number of publications, journals, countries, institutions, authors, keywords, and citations.

A total of 985 relevant documents were included in the analysis. From January 2013 to December 2022, the number of publications increased annually. The journal, institution, and author with the greatest number of publications in the field of TIPS are the Journal of Vascular and Interventional Radiology, the University of Bonn, and Jonel Trebicka, respectively. The main keywords used in this field are "transjugular intrahepatic portosystemic shunt", "portal hypertension", "cirrhosis", "management", "stent", "hepatic encephalopathy", "refractory ascite", "survival", "risk", and "variceal bleeding". The greatest obstacle to TIPS placement is currently the occurrence of hepatic encephalopathy. The research hotspots are the mechanism, risk factors, management, and control of hepatic encephalopathy.

This bibliometric analysis reported the research status and hotspots of TIPS. Research on postoperative hepatic encephalopathy is the research hotspot in this field.

Partial splenic artery embolization (PSAE) is an effective procedure for cirrhotic patients with hypersplenism. The aim of our study is to evaluate the effect of PSAE on skeletal muscle, and to identify the predictor for an improvement in skeletal muscle index (SMI) in cirrhotic patients with hypersplenism after PSAE.

466 cirrhotic patients with hypersplenism underwent PASE between Dec 2013 and Mar 2022. Medical records and CT images of enrolled patients were analyzed.

105 cirrhotic patients with hypersplenism were enrolled. Sarcopenia was observed in 60.00 % (63/105) of these patients, 68.25 % (43/63) of male patients, and 31.75 % (20/63) of female patients. In cirrhotic patients, no significant change in the mean SMI at the third lumbar vertebra (L3) level after PSAE. In patients with sarcopenia, the L3 SMI increased from 36.77 cm2/m2 (baseline) to 43.38 cm2/m2 (P < 0.01), the L3 subcutaneous fat area (SFA) increased from 79.16 cm2 (baseline) to 103.52 cm2 (P < 0.01) at 12-month follow-up after PSAE. In patients without sarcopenia, the L3 SMI decreased from 58.38 cm2/m2 (baseline) to 49.44 cm2/m2 (P < 0.05), the L3 SFA increased from 89.63 cm2 (baseline) to 94.77 cm2 (P > 0.05) at 12-month follow-up after PSAE. Univariate and multivariate analysis demonstrated splenic infarction rate (OR: 0.01, P = 0.0032) and SMI (OR: 0.84, P < 0.001) were independent predictors for an improvement in skeletal muscle in patients with sarcopenia.

In cirrhotic patients with sarcopenia, an improvement in skeletal muscle and fat mass was observed after PSAE; splenic infarction rate and the L3 SMI before PSAE predicted an improvement in skeletal muscle index in patients with sarcopenia after PSAE.

The consensus on whether Transjugular intrahepatic portosystemic shunt (TIPS) should be combined with variceal embolization in the treatment of portal hypertension-induced bleeding has not yet been reached. This study aimed to compare the difference in rebleeding incidence between TIPS and TIPS combined with variceal embolization and to analyze the optimal population for variceal embolization.

Clinical data of 721 patients undergoing TIPS were retrospectively collected. Patients were divided into two groups: TIPS alone (n = 155) and TIPS with embolization (TIPS+E, n = 251). Kaplan-Meier (KM) curves were used to analyze prognostic differences between the two groups, and subgroup analysis was conducted based on post-TIPS portal pressure gradient (PPG) exceeding 12 mmHg.

After TIPS placement, the mean PPG significantly decreased for all patients. A total of 51 patients (12.6 %) experienced rebleeding, with 24 cases (15.9 %) in the TIPS group and 27 cases (10.6 %) in the TIPS+E group. There was no significant difference in cumulative rebleeding incidence between the TIPS+E and TIPS groups. In the subgroup with post-TIPS PPG greater than 12 mmHg, the cumulative rebleeding incidence was significantly lower in the TIPS+E group compared to the TIPS group (HR = 0.47, 95 %CI = 0.24-0.93, Log rank P = 0.026). No significant difference was found in patients with a post-TIPS PPG less than 12 mmHg.

For patients with post-TIPS PPG exceeding 12 mmHg, simultaneous variceal embolization with TIPS placement significantly reduces the risk of rebleeding.

Transjugular intrahepatic portosystemic shunt (TIPS) has become essential in the treatment or prevention of portal hypertension-related complications. In the early 1990s, the primary indication was refractory bleeding. It is now proposed for the treatment of ascites for the prevention of bleeding and in patients with vascular diseases of the liver. Thus, there are a growing number of patients being treated with TIPS all over the world. The broadening of indications, the involvement of multiple stakeholders, the need for an accurate selection, the positioning in relation to transplantation and the lack of standardization in pre-therapeutic assessment, in the procedure itself and in the follow-up have led the board of the French Association for the Study of the Liver to establish recommendations.

Sarcopenia is common in patients with cirrhosis and is a risk factor for increased mortality. Transjugular intrahepatic portosystemic shunt (TIPS) placement has been utilized in cirrhosis patients with decompensation . We investigated the role of sarcopenia in predicting mortality in patients undergoing TIPS.

We conducted a single-center retrospective study of 232 patients with cirrhosis who underwent TIPS between January 2010 and December 2015. Sarcopenia was defined by the psoas muscle index (PMI) cutoff value, calculated based on dynamic time-dependent outcomes using X-tile software. Kaplan-Meier analysis demonstrated the difference in survival in the sarcopenia group versus the non-sarcopenia group. . Univariate and multivariate analyses were used to identify the relationship between sarcopenia and post-TIPS mortality during a follow-up period of 1 year.

For TIPS indications, 111 (47.84%) patients had refractory ascites, 69 (29.74%) patients had variceal bleeding, 12 (5.17%) patients had ascites, and 40 (17.24%) for other indications. The mean PMI was 4.40 ± 1.55. Sarcopenia was defined as a PMI value of <4.36 in males, and <3.23 in females. Sarcopenia was present in 96 (41.38%) of patients. . Kaplan-Meier analysis showed thatsarcopenia is associated with worse survival (log-rank P  < 0.01). Multivariate Cox regression analysis showed that sarcopenia is independently associated with worse survival during the 1-year follow-up period with an hazard ratio of 2.435 (95% CI 1.346-4.403) ( P  < 0.01), after adjusting for age, BMI, indications for TIPS, etiology for cirrhosis, and MELD score and stratified by sex.

Sarcopenia is an independent risk factor for 1-year mortality in patients undergoing TIPS and should be considered when patients are evaluated as a candidate for TIPS.

Transjugular intrahepatic portosystemic shunt (TIPS) is a commonly performed procedure in patients with liver cirrhosis to treat portal hypertension-related conditions, including variceal bleeding and refractory ascites. However, while the increased risk of hepatic encephalopathy (HE) after TIPS is important to consider when determining whether a patient is a good candidate for TIPS, currently there is no widely used method to predict the development of post-TIPS HE, although the model for end-stage liver disease (MELD) score is used to predict post-TIPS mortality. We conducted a systematic review and meta-analysis to evaluate sarcopenia as a risk factor for HE and mortality in patients undergoing TIPS.

A comprehensive search strategy was used to identify reports of post-TIPS HE and mortality in sarcopenia vs. non-sarcopenia patients with liver cirrhosis who received TIPS in March 2023. Open Meta Analyst was used to compute the results.

Twelve studies with 2056 patients met inclusion criteria and were included in the final meta-analysis. Sarcopenia was associated with a significantly higher post-TIPS HE rate than non-sarcopenia (risk ratio [RR]: 1.68, 95% CI: 1.48-1.92, p < 0.00001, I2 = 65%), as well as a significantly higher post-TIPS mortality rate (RR: 1.73, 95% CI: 1.14-2.64, p < 0.00001, I2 = 87%).

Patients with sarcopenia have a significantly increased risk of post-TIPS HE and mortality. Presence of sarcopenia should be considered when weighing the risks and benefits of performing TIPS in patients with cirrhosis. Further studies are needed to determine the clinical utility of important risk factors such as sarcopenia on post-TIPS outcomes.

The objective of this study was to investigate the effect of neutrophil-to-lymphocyte ratio (NLR) on the survival of cirrhotic patients with esophagogastric variceal bleeding (EGVB) treated with transjugular intrahepatic portosystemic shunt (TIPS).

A total of 293 patients treated with TIPS were included. The receiver operator characteristic curve (ROC) was used to calculate the optimal cut-off values of parameters such as NLR. The Kaplan-Meier curve and Cox proportional risk model were used to evaluate the effects of NLR and other variables on 2-year all-cause mortality.

The area under the ROC for NLR was 0.634, with an optimal cutoff value of 4.9. Two-year mortality rates for patients with high (≥4.9) and low (<4.9) NLR were 22.1% and 9.3%, respectively (Log rank test: P = 0.002). After correcting for confounders, multivariate analysis demonstrated that NLR ≥ 4.9 (HR = 2.741, 95% CI 1.467-5.121, P = 0.002), age ≥ 63 (HR = 3.403, 95% CI 1.835-6.310, P < 0.001), and gender (male) (HR = 2.842, 95% CI 1.366-5.912, P = 0.001) were independent risk factors for the mortality outcome. Considering the stratification of early and selective TIPS treatment, high NLR still significantly increased the risk of mortality for patients (Log rank test: P = 0.007, HR = 2.317, 95% CI 1.232-4.356).

NLR can help to predict survival in EGVB patients after TIPS, and the type of TIPS should also be considered in practical applications.

The association between sarcopenia and the effectiveness of neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC) remains uncertain. This study aims to examine the potential of sarcopenia as a predictive factor for the response to NAC in TNBC, and to assess whether its combination with MRI radiomic signatures can improve the predictive accuracy. We collected clinical and pathological information, as well as pretreatment breast MRI and abdominal CT images, of 121 patients with TNBC who underwent NAC at our hospital between January 2012 and September 2021. The presence of pretreatment sarcopenia was assessed using the L3 skeletal muscle index. Clinical models were constructed based on independent risk factors identified by univariate regression analysis. Radiomics data were extracted on breast MRI images and the radiomics prediction models were constructed. We integrated independent risk factors and radiomic features to build the combined models. The results of this study demonstrated that sarcopenia is an independent predictive factor for NAC efficacy in TNBC. The combination of sarcopenia and MRI radiomic signatures can further improve predictive performance.

Transjugular intrahepatic portosystemic shunt (TIPS) creation using the Viatorr stent remains relatively uncommon in underdeveloped and high-burden disease regions in Asia-Pacific, and there is a lack of comparative studies regarding its prognostic effects compared with the generic stent-graft/bare stent combination. The purpose of this retrospective study is to compare the prognostic endpoints of these two treatments in patients who underwent TIPS creation. Clinical data from 145 patients were collected, including 82 in the combination group and 63 in the Viatorr group. Differences in prognostic endpoints (shunt dysfunction, death, overt hepatic encephalopathy [OHE], rebleeding) between the two groups were analyzed using Kaplan-Meier curves. The Cox proportional hazards model was used to identify independent risk factors for post-TIPS shunt dysfunction. The TIPS procedure was successful in all patients. After TIPS creation, both groups showed a significant decrease in porto-caval pressure gradient compared to that before TIPS creation. The stent patency rates at 6, 12, and 18 months were high in both the combination and Viatorr groups (93.7%, 88.5%, and 88.5% vs. 96.7%, 93.4%, and 93.4%, respectively). The stent patency rates was higher in the combination group than in the Viatorr group, although not statistically significant (HR = 2.105, 95% CI 0.640-6.922, Log-rank P = 0.259). There were no significant differences in other prognostic endpoints (death, OHE, rebleeding) between the two groups. The Cox model identified portal vein diameter (HR = 0.807, 95% CI 0.658-0.990, P = 0.040) and portal vein thrombosis (HR = 13.617, 95% CI 1.475-125.678, P = 0.021) as independent risk factors for post-TIPS shunt dysfunction. The shunt patency rates between the Viatorr stent and the generic stent-graft/bare stent combination showed no significant difference and the generic stent-graft/bare stent combination may be a viable alternative in areas where the Viatorr stent is not yet available.

Sarcopenia is a potential risk factor for adverse outcomes in haematopoietic cell transplantation (HSCT) recipients. We aimed to explore longitudinal body changes in muscle and adipose mass and their prognostic value in allogeneic HSCT-treated severe aplastic anaemia (SAA) patients.

We retrospectively analysed consecutive SAA patients who underwent allogeneic HSCT between January 2017 and March 2022. Measurements of pectoral muscle and corresponding subcutaneous fat mass were obtained via chest computed tomography at baseline and at 1 month, 3 months, 6 months, and 12 months following HSCT. Sarcopenia was defined as pectoral muscle index (PMI) lower than the sex-specific median at baseline. Changes in body composition over time were evaluated by generalized estimating equations. Cox regression models were used to investigate prognostic factors affecting overall survival (OS) and failure-free survival (FFS). A nomogram was constructed from the Cox regression model for OS.

We included 298 adult SAA patients (including 129 females and 169 males) with a median age of 31 years [interquartile range (IQR), 24-39 years] at baseline. Sarcopenia was present in 148 (148/298, 50%) patients at baseline, 218 (218/285, 76%) patients post-1 month, 209 (209/262, 80%) patients post-3 month, 169 (169/218, 78%) patients post-6 month, and 129 (129/181, 71%) patients post-12 month. A significant decrease in pectoral muscle mass was observed in SAA patients from the time of transplant to 1 year after HSCT, and the greatest reduction occurred in post 1-3 months (P < 0.001). The sarcopenia group exhibited significantly lower 5-year OS (90.6% vs. 100%, log-rank P = 0.039) and 5-year FFS (89.2% vs. 100%, log-rank P = 0.021) than the nonsarcopenia group at baseline. Sarcopenia at baseline (hazard ratio, HR, 6.344; 95% confidence interval, CI: 1.570-25.538; P = 0.01; and HR, 3.275; 95% CI: 1.159-9.252; P = 0.025, respectively) and the delta value of the PMI at 6 months post-transplantation (ΔPMI6) (HR, 0.531; 95% CI: 0.374-0.756; P < 0.001; and HR, 0.666; 95% CI: 0.505-0.879; P = 0.004, respectively) were demonstrated to be independent prognostic factors for OS and FFS in SAA patients undergoing HSCT, and were used to construct the nomogram. The C-index of the nomogram was 0.75, and the calibration plot showed good agreement between the predictions made by the nomogram and actual observations.

Sarcopenia persists in SAA patients from the time of transplant to the 1-year follow-up after HSCT. Both sarcopenia at baseline and at 6 months following HSCT are associated with poor clinical outcomes, especially in patients with persistent muscle mass loss up to 6 months after transplantation.

As recommended by Baveno VII consensus, the utilization of pre-emptive transjugular intrahepatic portosystemic shunt (pTIPS) has been considered as standard therapeutic approach for the management of acute variceal bleeding (AVB) associated with cirrhosis., but the 72-h window for pTIPS is too narrow. This study aimed to compare the clinical outcomes between patients who received <72 h pTIPS and 72 h-5d pTIPS. In this study, a total of 63 cirrhotic patients with AVB who underwent pTIPS between October 2016 and December 2021 were included in this retrospective study. They were divided into <72 h group (n = 32) and 72 h-5d group (n = 31), based on the timing of the intervention. The Kaplan-Meier curves demonstrated that there were no significant differences in the cumulative incidence of death (22.3% ± 7.4% vs. 19.9% ± 7.3%, log-rank P = 0.849), variceal rebleeding (9.7% ± 5.3% vs. 17.8% ± 7.3%, log-rank P = 0.406), OHE (28.5% ± 8.0% vs. 23.9% ± 8.0%, log-rank P = 0.641) and shunt dysfunction (8.6% ± 6.0% vs. 17.4% ± 8.1%, log-rank P = 0.328) between <72 h and 72 h-5d groups. In the total cohort, sarcopenia was identified as an independent risk factor for mortality (HR = 11.268, 95% CI = 1.435-88.462, P = 0.021) and OHE(HR = 12.504, 95% CI = 1.598-97.814, P = 0.016). In conclusion, the clinical outcomes of cirrhotic patients with AVB who underwent pTIPS within the 72-h to 5-day window were found to be comparable to those treated within the 72-h window.

Malnutrition and sarcopenia have been reported to adversely affect the outcome of patients with cirrhosis of the liver. There is an emerging body of evidence suggesting malnutrition and sarcopenia increase the risk of hepatic encephalopathy (HE) and mortality after transjugular intrahepatic portosystemic shunt (TIPS). The current systematic review aims to determine whether the body of evidence supports an association between nutritional status and post-TIPS outcomes in patients with cirrhosis.

Electronic databases of PubMed, Embase, and Scopus were searched from inception to June 3, 2023, for studies analysing the effect of nutritional status on post-TIPS outcomes in patients with cirrhosis.

A total of 22 studies were included in the systemic review. Assessment of sarcopenia was done by skeletal muscle index (SMI) at the L3 level, transversal psoas muscle thickness, psoas muscle density, malnutrition as per ICD, relative sarcopenia with excess adiposity, lipid profile, controlling nutritional status score, body composition analysis, hospital frailty risk score, and visceral and subcutaneous fat area index. Ten out of 12 studies in this systematic review showed a significant association with the incidence of post-TIPS HE. Thirteen out of 14 studies reported that the presence of malnutrition was associated with increased odds of mortality following TIPS. One study reported sarcopenia as an independent predictor of liver failure, and another study reported that Pre-TIPS SMI was an independent predictor of substantial improvement in post-TIPS SMI.

The current systematic review shows that the presence of pre-TIPS malnutrition or sarcopenia is an independent predictor of adverse outcomes after TIPS. Incorporating these parameters into present prediction models can provide additional prognostic information.

Nutritional assessment should be part of the evaluation of patients planned for TIPS for prediction of adverse events after the procedure.

The association between the presence of sarcopenia in patients with cirrhosis and the onset of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) is yet to be established. We conducted a systematic review and meta-analysis to provide a thorough summary of the available evidence on this association.

A thorough search of the literature was performed in the PubMed, EMBASE, and Web of Science databases. The protocol was duly registered on PROSPERO (CRD42023398856). The hazard ratio (HR) and corresponding 95% confidence intervals (CIs) for the occurrence of HE after TIPS were extracted from studies comparing cirrhotic patients with and without sarcopenia. These data were then combined using a random-effect model.

A total of 1135 patients from seven cohort studies that met our eligibility criteria were included in the meta-analysis. Our findings indicate a significantly higher risk of post-TIPS HE among cirrhotic patients with sarcopenia compared to those without sarcopenia (HR, 2.35; 95% CIs 1.32-4.19; p = 0.004; I2 = 75%). The findings remained consistent across subgroups stratified by liver disease etiology, study location, and severity of hepatic dysfunction.

The study demonstrated that sarcopenia was strongly linked to an increased likelihood post-TIPS HE among cirrhotic patients.

To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) on clinical outcomes and liver histology in patients with hepatic sinusoidal obstruction syndrome (HSOS) caused by pyrrolizidine alkaloids (PA), and compare these results with those of patients who received supportive treatment alone.

From June 2015 to August 2022, 164 patients diagnosed with PA-HSOS in six tertiary care centers were retrospectively included in this study and divided into TIPS group (n = 69) and supportive treatment (ST) group (n = 95). The main endpoint was to determine whether TIPS placement could improve survival in PA-HSOS patients. The clinical symptoms associated with portal hypertension were also evaluated in this study. Additionally, a small TIPS-subgroup of 7 patients received liver biopsies before and after TIPS for histological analysis.

The incidence of death was markedly lower in the TIPS group than in the ST group (log-rank p = 0.026). Multivariate Cox model revealed that group assignment (hazard ratio (HR) 5.146; 95 % confidence interval (CI) 1.587-16.687; p = 0.006), total bilirubin (HR 1.029; 95 % CI 1.020-1.038; p < 0.001), and INR (HR 13.291; 95 % CI 3.637-48.566; p < 0.001) were independent predictors for mortality. In addition, TIPS placement reduced the risk of complications associated with portal hypertension but did not increase the rate of overt hepatic encephalopathy (log-rank p = 0.731). Furthermore, six of 7 TIPS patients receiving liver biopsies improved after TIPS placement, and one patient developed fibrosis.

TIPS placement decreased the mortality and risk of complications associated with portal hypertension. Histological evaluation in a few patients showed a potential improvement by TIPS.

Sarcopenia is associated with poor outcomes in patients with cirrhosis. However, the prevalence of and associated factors for developing sarcopenia in this population remain to be determined.

This study aimed to summarize the prevalence, characteristics, and associated factors of sarcopenia in patients with cirrhosis.

Electronic searches were performed from inception to June 9, 2022 to identify the eligible studies. We meta-analyzed the prevalence of sarcopenia in overall patients with cirrhosis and subgroups. Both crude and adjusted odds ratios (ORs) were pooled using the random effects model.

A total of 55 studies involving 13,158 patients from 17 countries were included. The overall prevalence of sarcopenia was 40.1 % (95 % CI 35.4%-44.9 %) in patients with cirrhosis. The pooled prevalence was higher in males, Child-Pugh class C cirrhosis, decompensated stage, ascites, subjective global assessment class C cirrhosis, and when sarcopenia was defined by L3-SMI (third lumbar-skeletal muscle index) at a higher cutoff. In multivariate analysis, older age (adjusted OR 1.04, 95 % CI 1.00-1.07), male (adjusted OR 4.75, 95 % CI 2.72-8.28), lower body mass index (BMI) (adjusted OR 0.78, 95 % CI 0.73-0.83), alcoholic liver disease (ALD) (adjusted OR 1.43, 95 % CI 1.19-1.72), but not ascites and hepatic encephalopathy, were significantly associated with an increased risk of sarcopenia in patients with cirrhosis.

Sarcopenia is a prevalent complication, and older age, male patients, lower BMI, and patients with ALD are associated with an increased risk of sarcopenia in patients with cirrhosis.

Malnutrition and sarcopenia are highly prevalent in patients with decompensated cirrhosis and are associated with poorer clinical outcomes. Their pathophysiology is complex and multifactorial, with protein-calorie malnutrition, systemic inflammation, reduced glycogen stores and hormonal imbalances all well reported. The direct contribution of portal hypertension to these driving factors is however not widely documented in the literature. This review details the specific mechanisms by which portal hypertension directly contributes to the development of malnutrition and sarcopenia in cirrhosis. We summarise the existing literature describing treatment strategies that specifically aim to reduce portal pressures and their impact on nutritional and muscle outcomes, which is particularly relevant to those with end-stage disease awaiting liver transplantation.

Surgeons have historically used age as a preoperative predictor of postoperative outcomes. Sarcopenia, the loss of skeletal muscle mass due to disease or biological age, has been proposed as a more accurate risk predictor. The prognostic value of sarcopenia assessment in surgical patients remains poorly understood. Therefore, the authors aimed to synthesize the available literature and investigate the impact of sarcopenia on perioperative and postoperative outcomes across all surgical specialties.

The authors systematically assessed the prognostic value of sarcopenia on postoperative outcomes by conducting a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching the PubMed/MEDLINE and EMBASE databases from inception to 1st October 2022. Their primary outcomes were complication occurrence, mortality, length of operation and hospital stay, discharge to home, and postdischarge survival rate at 1, 3, and 5 years. Subgroup analysis was performed by stratifying complications according to the Clavien-Dindo classification system. Sensitivity analysis was performed by focusing on studies with an oncological, cardiovascular, emergency, or transplant surgery population and on those of higher quality or prospective study design.

A total of 294 studies comprising 97 643 patients, of which 33 070 had sarcopenia, were included in our analysis. Sarcopenia was associated with significantly poorer postoperative outcomes, including greater mortality, complication occurrence, length of hospital stay, and lower rates of discharge to home (all P <0.00001). A significantly lower survival rate in patients with sarcopenia was noted at 1, 3, and 5 years (all P <0.00001) after surgery. Subgroup analysis confirmed higher rates of complications and mortality in oncological (both P <0.00001), cardiovascular (both P <0.00001), and emergency ( P =0.03 and P =0.04, respectively) patients with sarcopenia. In the transplant surgery cohort, mortality was significantly higher in patients with sarcopenia ( P <0.00001). Among all patients undergoing surgery for inflammatory bowel disease, the frequency of complications was significantly increased among sarcopenic patients ( P =0.007). Sensitivity analysis based on higher quality studies and prospective studies showed that sarcopenia remained a significant predictor of mortality and complication occurrence (all P <0.00001).

Sarcopenia is a significant predictor of poorer outcomes in surgical patients. Preoperative assessment of sarcopenia can help surgeons identify patients at risk, critically balance eligibility, and refine perioperative management. Large-scale studies are required to further validate the importance of sarcopenia as a prognostic indicator of perioperative risk, especially in surgical subspecialties.

Transjugular intrahepatic portosystemic shunt (TIPS) has been extensively used to treat portal hypertension-associated complications, including cirrhosis. The prediction of post-TIPS prognosis is important for cirrhotic patients, as more aggressive liver transplantation is needed when the post-TIPS prognosis is poor.

To construct a nutrition-based model that could predict the disease progression of cirrhotic patients after TIPS implantation in a sex-dependent manner.

This study retrospectively recruited cirrhotic patients undergoing TIPS implantation for analysis. Muscle quality was assessed by measuring the skeletal muscle index (SMI) by computed tomography. Multivariate Cox proportional hazard models were utilized to determine the association between SMI and disease progression in cirrhotic patients after TIPS implantation.

This study eventually included 186 cirrhotic patients receiving TIPS who were followed up for 30.5 ± 18.8 mo. For male patients, the 30-mo survival rate was significantly lower and the probability of progressive events was higher (3.257-fold) in the low-level SMI group than in the high-level SMI group. According to the multivariate Cox analysis of male patients, SMI < 32.8 was an independent risk factor for long-term adverse outcomes after TIPS implantation. A model was constructed, which involved creatinine, plasma ammonia, SMI, and acute-on-chronic liver failure and hepatic encephalopathy occurring within half a year after surgery. This model had an area under the receiver operating characteristic curve of 0.852, sensitivity of 0.926, and specificity of 0.652. According to the results of the DeLong test, this model outperformed other models (Child-Turcotte-Pugh, Model for End-Stage Liver Disease, and Freiburg index of post-TIPS survival) (P < 0.05).

SMI is strongly associated with poor long-term outcomes in male patients with cirrhosis who underwent TIPS implantation.

Malnutrition is a tangible complication of cirrhosis with portal hypertension with a prevalence of up to 50%. In particular, sarcopenia and myosteatosis, defined as the alteration in muscle quantity and quality, have a negative impact on the main complications of liver disease and are associated with higher mortality in patients with cirrhosis. Recently, alterations in adipose tissue have also been described in cirrhotic patients and they seem to influence the course of liver disease. Several pieces of evidence indicate that a transjugular intrahepatic portosystemic shunt (TIPS), placed for the treatment of refractory portal hypertension, can lead to a modification of body composition consisting in the improvement of the skeletal muscle index, myosteatosis, and an increase in subcutaneous fat. These modifications of the nutritional status, even more pronounced in sarcopenic patients before TIPS, have been associated with an amelioration of cognitive impairment after TIPS as well as with an increase in the survival rate. The aim of this paper is to provide an overview of the effects of TIPS placement on nutritional status in cirrhosis focusing on its pathophysiological mechanisms and its relationship with liver-related outcomes.

To validate a novel deep learning-based metal artifact correction (MAC) algorithm for CT, namely, AI-MAC, in preclinical setting with comparison to conventional MAC and virtual monochromatic imaging (VMI) technique.

An experimental phantom was designed by consecutively inserting two sets of pedicle screws (size Φ 6.5 × 30-mm and Φ 7.5 × 40-mm) into a vertebral specimen to simulate the clinical scenario of metal implantation. The resulting MAC, VMI, and AI-MAC images were compared with respect to the metal-free reference image by subjective scoring, as well as by CT attenuation, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and correction accuracy via adaptive segmentation of the paraspinal muscle and vertebral body.

The AI-MAC and VMI images showed significantly higher subjective scores than the MAC image (all p < 0.05). The SNRs and CNRs on the AI-MAC image were comparable to the reference (all p > 0.05), whereas those on the VMI were significantly lower (all p < 0.05). The paraspinal muscle segmented on the AI-MAC image was 4.6% and 5.1% more complete to the VMI and MAC images for the Φ 6.5 × 30-mm screws, and 5.0% and 5.1% for the Φ 7.5 × 40-mm screws, respectively. The vertebral body segmented on the VMI was closest to the reference, with only 3.2% and 7.4% overestimation for Φ 6.5 × 30-mm and Φ 7.5 × 40-mm screws, respectively.

Using metal-free reference as the ground truth for comparison, the AI-MAC outperforms VMI in characterizing soft tissue, while VMI is useful in skeletal depiction.

Background Sarcopenia is considered a prognostic factor for advanced chronic liver disease (ACLD) independent of liver function, but the underlying mechanisms are unknown. Here, we investigated whether sarcopenia contributed to hepatic decompensation and worsened prognosis. Methods This was a single-center retrospective study of 708 patients with chronic liver disease who underwent magnetic resonance elastography (MRE). Magnetic resonance imaging (MRI) was used to diagnose sarcopenia and hepatic decompensation (presence of ascites). Results The incidence of sarcopenia (29% overall) and age were significantly correlated to increased liver stiffness (LS) (p < 0.01 each), but age did not differ for LS ≥ 4 kPa. Rates of thrombocytopenia and varices increased at ≥4 kPa, and ascites (n = 52) accounted for 81% of patients with ≥6 kPa LS. Age, alcoholic liver disease, C-reactive protein, sodium level, and controlling nutritional status score were extracted as factors contributing to sarcopenia (all p < 0.05). In ACLD, sarcopenia was an independent predictor of ascites (p < 0.01), and in a follow-up analysis of 163 patients without ascites at baseline, the incidence of ascites in patients with sarcopenia was significantly higher, even after adjusting for LS and liver severity (p < 0.01). The Cox proportional hazards model indicated albumin-bilirubin score and sarcopenia as independent prognostic factors (p < 0.01 each). Conclusions In ACLD, both portal hypertension and liver disease-related sarcopenia were found to occur at ≥4 kPa. Sarcopenia was accompanied by mildly decreased sodium levels and contributed to the early development of ascites and poor prognosis, independent of liver function.

It is widely known that muscle mass influences the outcomes of many chronic diseases. Erector spine mass is a convenient parameter obtained from routine abdominal computed tomography (CT). The clinical application value of erector spine mass, and whether erector spine mass could predict the outcome of disease has not been studied.

To evaluate the role of the erector spine index (ESI) calculated based on abdominal CT imaging in the progression of acute-on-chronic liver failure related to the hepatitis B virus (HBV-ACLF).

We performed a retrospective study of 118 HBV-ACLF patients and calculated the ESI (the total erector spine area normalized for height2 in meters) for each patient through abdominal CT. The findings were analyzed regarding the progression of HBV-ACLF and the ESI at baseline, including mortality and the development of complications.

The ESI level was associated with mortality and the development of complications. During the 90-day follow-up period, patients with a low ESI (<12.05 cm2/m2) had higher mortality than those with a high ESI (≥ 12.05 cm2/m2) (51.7% vs. 26.7%), and the cumulative survival rates were 71.0%±4.6 and 85.8%±3.9, respectively (log-rank P = 0.003). The hazard ratios (HRs) calculated using univariable and multivariable analyses were 2.23(95% confidence interval (CI): 1.25-4.21, P = 0.005) and 2.52 (95% CI: 1.34-9.24, P = 0.011), respectively. Patients with a low ESI (<12.05 cm2/m2) had higher incidences of kidney dysfunction (43.5% vs. 23.2%, P = 0.029; log-rank P = 0.017) and hepatic encephalopathy (39.6% vs. 14.0%, P = 0.003; log-rank P = 0.010) than those with a high ESI. A low ESI was an independent risk factor for kidney dysfunction (adjusted HR = 1.36, 95% CI: 1.05-2.93, P = 0.043) and the development of hepatic encephalopathy (adjusted HR = 2.26; 95% CI: 2.05-3.13, P = 0.036). In addition, the presence of hepatic encephalopathy (the odds ratio (OR) = 2.26, 95% CI: 2.05-3.18, P = 0.006), spontaneous bacterial peritonitis (OR = 3.95, 95% CI: 1.01-5.46, P = 0.037), and kidney dysfunction (OR = 4.47, 95% CI: 1.02-9.64, P = 0.032) was independently associated with a low ESI in patients.

A low ESI is an independent risk factor for mortality in patients with HBV-ACLF, as well as the development of kidney dysfunction and hepatic encephalopathy.
