Background: 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.
Aim: To construct a nutrition-based model that could predict the disease progression of cirrhotic patients after TIPS implantation in a sex-dependent manner.
Methods: 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.
Results: 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) ( < 0.05).
Conclusion: SMI is strongly associated with poor long-term outcomes in male patients with cirrhosis who underwent TIPS implantation.

Bacterial translocation-induced inflammation and immune dysfunction are recognised factors contributing to the pathogenesis of primary biliary cholangitis (PBC). However, the specific involvement of interferons (IFNs) and soluble checkpoints (sol-CRs) in shaping the immune landscape in PBC patients remains unexplored. Furthermore, the influence of ursodeoxycholic acid (UDC) on these immune mediators is unknown.

The microbiome of the human intestine is a regulator of health that modulates immune response and plays an important role in metabolism. The diversity, and abundance of microbiota communities in the gut have been shown to change in cirrhosis and its complications. We aimed to review the current knowledge regarding microbiota alterations in cirrhosis, its potential differences according to etiology, and its role in the development of cirrhosis complications.

Low-grade chronic inflammation may impact liver disease. We investigated the extent to which circulating GlycA, a glycoprotein biomarker of low-grade inflammation, and high-sensitivity C-reactive protein (hs-CRP) are altered in patients with cirrhosis and liver transplant recipients (LTRs) and examined their associations with all-cause mortality. Plasma GlycA (nuclear magnetic resonance spectroscopy) and hs-CRP (nephelometry) were assessed in 129 patients with cirrhosis on the waiting list for liver transplantation and 367 LTRs (TransplantLines cohort study; NCT03272841) and compared with 4837 participants from the population-based PREVEND cohort.

Cirrhotic cardiomyopathy (CCM) is a diagnostic entity defined as cardiac dysfunction (diastolic and/or systolic) in patients with liver cirrhosis, in the absence of overt cardiac disorder. Pathogenically, CCM stems from a combination of systemic and local hepatic factors that, through hemodynamic and neurohormonal changes, affect the balance of cardiac function and lead to its remodeling. Vascular changes in cirrhosis, mostly driven by portal hypertension, splanchnic vasodilatation, and increased cardiac output alongside maladaptively upregulated feedback systems, lead to fluid accumulation, venostasis, and cardiac dysfunction.

Background: Cirrhosis is a medical condition marked by persistent liver damage, which leads to the development of fibrous tissue and compromised liver function. In the present study, we decided to investigate the possibility of a connection between the consumption of fermentable olig-, di-, monosaccharides, and polyols (FODMAPs) and mortality rates in cirrhotic patients by utilizing data obtained from a prospective cohort study.
Methods: This cohort study enrolled 166 ambulatory patients from two hospitals in Tehran, Iran, between 2016 and 2018, and followed them up for 5 48 months until April 30, 2022.
