Introduction: Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by polyserositis and arthritis attacks, which are mediated by increased plasma levels of cytokines. Our hypothesis was that the increase in specific cytokines can also lead to portal hypertension, even in the absence of overt hepatic steatosis.
Methods: We designed a comparative cross-sectional study with 41 patients and 30 healthy individuals to show if there is a relationship between portal hypertension and FMF. B mode ultrasound and Doppler ultrasound were utilized to evaluate liver echogenicity, portal vein diameter, peak portal blood flow velocity, and portal vein flow direction, which are important diagnostic criteria for portal hypertension.
Results: Spleen and liver sizes and portal vein diameters of the FMF patients and the healthy controls were not significantly different. Imaging of 4 patients revealed periportal cuffing and one patient with periportal cuffing also had a fine granular appearance of the liver. The peak portal blood flow velocity of the FMF patients was lower than that of the control group (p<0.007).
Conclusion: The FMF group had significantly lower peak portal blood flow velocity than the control group, indicating the existence of portal hypertension. However, the differences between the other findings that correlate with portal hypertension were not significant.

Hemodynamic investigations on the portal hypertension and treatment of transjugular intrahepatic portosystemic shunt (TIPS) based on CFD simulation.

Hemodynamic processes from the portal vein(PV) to the inferior vena cava(IVC) were mimicked for three patients with portal hypertension(PH) and the effects of stent parameters on the outcomes of transjugular intrahepatic portosystemic shunt(TIPS) were investigated through computational fluid dynamics(CFD). The liver region was simulated with porous media model and the spatial distributions of superior mesenteric vein(SMV) and splenic vein(SV) blood were solved through the Eulerian multiphase model. The present method is able to simulate the PH flow and predict the PV pressure, the stent shunt rate and the SMV blood proportion after TIPS treatment.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.

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.

Background: Cirrhotic patients face heightened energy demands, leading to rapid glycogen depletion, protein degradation, oxidative stress, and inflammation, which drive disease progression and complications. These disruptions cause cellular damage and parenchymal changes, resulting in vascular alterations, portal hypertension, and liver dysfunction, significantly affecting patient prognosis.
Aim: To analyze the association between Child-Turcotte-Pugh (CTP) scores and different nutritional indicators with survival in a 15-year follow-up cohort.
Preventing the progression of cirrhosis to decompensation and death.

Two main stages are differentiated in patients with advanced chronic liver disease (ACLD), one compensated (cACLD) with an excellent prognosis, and the other decompensated (dACLD), defined by the appearance of complications (ascites, variceal bleeding and hepatic encephalopathy) and associated with high mortality. Preventing the progression to dACLD might dramatically improve prognosis and reduce the burden of care associated with ACLD. Portal hypertension is a major driver of the transition from cACLD to dACLD, and a portal pressure of ≥10 mmHg defines clinically significant portal hypertension (CSPH) as the threshold from which decompensating events may occur.
