Review article: depression and the use of antidepressants in patients with chronic liver disease or liver transplantation

Hepatic encephalopathy (HE) is a significant complication of both acute and chronic liver disease, causing much morbidity and mortality. It is a complex neuropsychological condition, associated with hyperammonaemia and systemic inflammation, with a wide spectrum of symptoms. The West Haven criteria describe grades of severity from 0 (subclinical) and I (changes in awareness, mood, attention, cognition, and sleep pattern) through to IV (coma). It is further classified by the underlying aetiology: type A, due to acute liver failure; type B, secondary to portosystemic shunting; and type C, occurring in chronic liver disease in association with precipitating factors including infections, gastrointestinal bleeding, and electrolyte disorders, particularly hyponatraemia. There is no definitive test or set of diagnostic criteria to establish a diagnosis of HE, which remains primarily a clinical diagnosis of exclusion in patients with a history or clinical evidence of liver disease. Management depends on the type of HE, but for type C (the commonest type) typically includes lactulose and rifaximin. Patients with cirrhosis with ongoing overt HE despite optimal medical management have a dismal outlook and should be considered promptly for liver transplantation.

Background/Aims: One hallmark of chronic liver disease in patients with portal hypertension is the formation of portal-systemic collaterals in which angiogenesis has a fundamental role. We studied patients with chronic liver disease undergoing liver transplantation to correlate levels of circulating angiogenic factors in portal and peripheral circulation with portal pressure and portal-systemic collaterals. Methods: Sixteen patients who underwent liver transplantation were enrolled. During transplant surgery, we determined portal venous pressure and portal-systemic collateral formation. We determined angiogenics mediator levels in systemic and portal plasma. Peripheral plasma from healthy donors was measured as controls. Results: Vascular endothelial growth factor (VEGF)-R1 and 2, Ang-1 and 2, Tie2, FGF- 1 and 2, CD163, PDGFR-β, PDGFsRα, PDGF-AB and BB, CD163, TGF-β VASH-1 levels were significantly different in the controls in comparison to cases. Significantly decreased portal venous levels of Ang-1, FGF-1, PDGF-AB/BB, and CC were observed in patients with higher portal pressure. Peripheral VEGF, Ang-1, pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation. While peripheral VEGF-R1 was higher in patients with severe collateral formation. For portal circulation, VEGF, Ang-1, pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation Conclusions: Angiogenesis factors correlated with portal pressure and collateral formation and different patterns of circulating angiogenesis mediators were found in peripheral and portal blood of patients with chronic liver disease. These results support the importance of angiogenic pathways in cirrhosis and portal hypertension and highlight areas for further study to identify clinically useful noninvasive markers of portal pressure and collateral formation.
