OBJECTIVES: One of the striking features of splenic imaging is variable heterogeneous gyriform arterial enhancement on dynamic computed tomography (CT). We speculated that these patterns of arterial enhancement may reflect changes in splenic micro-circulation related to changes in portal venous pressure. PATIENTS AND METHODS: To test this hypothesis, we evaluated arterial phase CT scans performed before and after liver transplantation (n=91), as this is the most effective way of alleviating portal hypertension...

A 61-year-old man with well-controlled diabetes mellitus type 2, cirrhosis from hepatitis C, alcohol abuse, and portal hypertension presented with painful vision loss and left orbital swelling. Imaging showed diffuse orbital, perineural, and pachymeningeal inflammation. He was initially diagnosed with neurosarcoidosis. However, cerebrospinal fluid analysis revealed central nervous system lymphoma, and lacrimal gland biopsy showed fungal organisms consistent with mucormycosis. The authors describe a case of Mucorales infection lacking sinonasal involvement and discuss the differential diagnosis and management of patients presenting with orbital and central nervous system inflammation from this uncommon fungal infection...

Portal hypertension is the main driver of cirrhosis decompensation, the main determinant of death in patients with cirrhosis. Portal hypertension results initially from increased intrahepatic vascular resistance. Later, increased inflow from splanchnic vasodilation and increased cardiac output lead to a further increase in portal pressure. Reducing portal pressure in cirrhosis results in better outcomes. Removing the cause of cirrhosis might improve portal pressure. However, this is a slow process and patients may continue to be at risk of decompensation...

OBJECTIVE: Emergency surgery is a risk factor for mortality in cirrhotic patients. Portal hypertension is an essential feature of decompensated cirrhosis. This study aimed to assess the value of portal venous pressure (PVP) measurement in prediction of 1-month mortality in cirrhotic patients undergoing emergency laparotomy. METHODS: This prospective study included 121 adults with liver cirrhosis subjected to an emergency laparotomy. Child-Turcotte-Pugh (CTP) score and model for end-stage liver disease (MELD) score were used for preoperative patient evaluation...

BACKGROUND: Baveno-VI guidelines recommend that patients with compensated cirrhosis with liver stiffness by transient elastography (LSM-TE) <20 kPa and platelets >150,000/mm3 do not need an esophagogastroduodenoscopy (EGD) to screen for varices, since the risk of having varices needing treatment (VNT) is <5%. It remains uncertain if this tool can be used in patients with cholestatic liver diseases (ChLDs): primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC)...

Gut microbiota is the largest collection of commensal microorganisms in the human body, engaged in reciprocal cellular and molecular interactions with the liver. This mutually beneficial relationship may break down and result in dysbiosis, associated with disease phenotypes. Altered composition and function of gut microbiota has been implicated in the pathobiology of nonalcoholic fatty liver disease (NAFLD), a prevalent condition linked to obesity, insulin resistance, and endothelial dysfunction. NAFLD may progress to cirrhosis and portal hypertension, which is the result of increased intrahepatic vascular resistance and altered splanchnic circulation...

RATIONALE: Bone Morphogenetic Protein 9 (BMP9) is a circulating endothelial quiescence factor with protective effects in pulmonary arterial hypertension (PAH). Loss-of-function mutations in BMP9, its receptors and downstream effectors have been reported in heritable PAH. OBJECTIVES: We sought to determine how an acquired deficiency of BMP9 signaling might contribute to PAH. METHODS AND RESULTS: Plasma levels of BMP9 and antagonist soluble Endoglin (sEng) were measured in Group 1 PAH, Group 2 and 3 pulmonary hypertension (PH), and in patients with severe liver disease without PAH...

Previous reports of lung function in cystic fibrosis (CF) patients with liver disease have shown worse, similar, or even better forced expiratory volume in 1 second (FEV1), compared to CF patients without liver disease. Varying definitions of CF liver disease likely contribute to these inconsistent relationships reported between CF lung function and liver disease. We retrospectively evaluated spirometric data in 179 subjects (62% male; 58% Phe508del homozygous) with severe CF liver disease (CFLD; defined by presence of portal hypertension due to cirrhosis)...

BACKGROUND Sarcoidosis is a systemic disease that can affect any organ, including the liver. It is manifested by the presence of non-caseating granulomas within involved organs, most commonly the pulmonary, lymphatic, and hepatic system. Unlike pulmonary or lymphatic involvement, hepatic involvement is usually asymptomatic and it is underdiagnosed. Here, we report a case of a patient with a history of pulmonary sarcoidosis who developed hepatic sarcoidosis. CASE REPORT 68-year-old female with pulmonary sarcoidosis with a 2-week history of severe abdominal pain and epigastric tenderness presented to our center...

BACKGROUND/AIMS: In patients who survive the first esophageal variceal bleeding (EVB) resulting from portal hypertension, the probability of fatal esophageal variceal re-bleeding (EVR) is high. We have developed a sandwich-style sequential therapy combining laparoscopic splenectomy and azygoportal disconnection (LSD) with preoperative and postoperative endoscopic intervention (LSDE). The aim of the present study was to investigate whether LSDE is safe and effective and to evaluate whether the postoperative EVR rate for LSDE was lower than that for LSD without periodical postoperative endoscopic intervention (NLSDE)...

BACKGROUND: Liver fibrosis can progress to cirrhosis, hepatocellular carcinoma, or liver failure. Unfortunately, the antifibrotic agents are limited. Thrombin activates hepatic stellate cells (HSCs). Therefore, we investigated the effects of a direct thrombin inhibitor, dabigatran, on liver fibrosis. METHODS: Adult male Sprague-Dawley rats were injected intraperitoneally with thioacetamide (TAA, 200 mg/kg twice per week) for 8 or 12 weeks to induce liver fibrosis...

Background: Terlipressin is used as pharmacological treatment for variceal bleeding. The drug's physiological effect favours hyponatremia, and rapid changes in plasma sodium (PNa) may cause brain injury. Cirrhosis patients seem to be largely protected against this effect but patients without cirrhosis may not be so. Objective: The objective of this study was to examine whether terlipressin treatment of patients without cirrhosis leads to more serious fluctuations in PNa than in cirrhosis...

REVIEW
Wen Xu, Ping Liu, Yong-Ping Mu
Portal hypertension (PHT) is an important consequence of liver cirrhosis, which can lead to complications that adversely affect a patient's quality of life and survival, such as upper gastrointestinal bleeding, ascites, and portosystemic encephalopathy. In recent years, advances in molecular biology have led to major discoveries in the pathological processes of PHT, including the signaling pathways that may be involved: PI3K-AKT-mTOR, RhoA/Rho-kinase, JAK2/STAT3, and farnesoid X receptor. However, the pathogenesis of PHT is complex and there are numerous pathways involved...
