Total area of spontaneous portosystemic shunts independently predicts hepatic encephalopathy and mortality in liver cirrhosis.

Pathophysiology of decompensated cirrhosis: Portal hypertension, circulatory dysfunction, inflammation, metabolism and mitochondrial dysfunction.

The term cirrhosis-associated immune dysfunction (CAID) comprises the distinctive spectrum of immune alterations associated with the course of end-stage liver disease. Systemic inflammation and immune deficiency are the key components of CAID. Their severity is highly dynamic and progressive, paralleling cirrhosis stage. CAID involves two different immune phenotypes: the low-grade systemic inflammatory phenotype and the high-grade systemic inflammatory phenotype. The low-grade systemic inflammatory phenotype can be found in patients with compensated disease or clinical decompensation with no organ failure. In this phenotype, there is an exaggerated immune activation but the effector response is not markedly compromised. The high-grade systemic inflammatory phenotype is present in patients with acute-on-chronic liver failure, a clinical situation characterized by decompensation, organ failure and high short-term mortality. Along with high-grade inflammation, this CAID phenotype includes intense immune paralysis that critically increases the risk of infections and worsens prognosis. The intensity of CAID has important consequences on cirrhosis progression and correlates with the severity of liver insufficiency, bacterial translocation and organ failure. Therapies targeting the modulation of the dysfunctional immune response are currently being evaluated in preclinical and clinical studies.

In this review, we summarise the current knowledge on the indications and contraindications of transjugular intrahepatic portosystemic shunt (TIPS) placement for the treatment of the complications of portal hypertension in cirrhosis, specifically variceal haemorrhage and ascites. Moreover, we discuss the role of TIPS for the treatment of portal vein thrombosis (PVT) and the prevention of complications after extrahepatic surgery ('preoperative TIPS') in patients with cirrhosis. The position of TIPS in the treatment hierarchy depends on the clinical setting and on patient characteristics. In acute variceal haemorrhage, preemptive TIPS is indicated in patients at a high risk of failing standard therapy, that is those with a Child-Pugh score of 10-13 points or Child-Pugh B with active bleeding at endoscopy, although the survival benefit in the latter group still remains to be established. Non-preemptive TIPS is a second-line therapy for the prevention of recurrent variceal haemorrhage and for the treatment of ascites. Of note, TIPS may also improve sarcopenia. Contraindications to TIPS placement, independent of clinical setting, include very advanced disease (Child-Pugh >13 points), episodes of recurrent overt hepatic encephalopathy without an identifiable precipitating factor, heart failure, and pulmonary hypertension. In patients with PVT, TIPS placement not only controls complications of portal hypertension, but also promotes portal vein recanalisation. Although the severity of portal hypertension correlates with poor outcomes after extrahepatic surgery, there is no evidence to recommend preoperative TIPS placement.
