Hyperhomocysteinemia is linked to MASLD.

Background And Aims: Homocysteine (Hcy) levels are elevated in different conditions, including cardiovascular diseases (CVD), diabetes, and metabolic-associated steatotic liver disease (MASLD). In this observational retrospective study, we analyzed Hcy levels in a population of 901 outpatients, considering its putative etiological role in MASLD.

Methods: A total of 901 outpatients underwent physical and biochemical evaluations.

Fatty Liver Index (FLI) is the best score to predict MASLD with 50% lower cut-off value in women than in men.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is defined by the presence of hepatic steatosis, detected on ultrasonography (US) imaging or histology, and at least one of criteria for Metabolic Syndrome diagnosis. Simple non-invasive tests (NITs) have been proposed as an acceptable alternative when US and biopsy are not available or feasible but have not been validated for MASLD. In this observational study, we investigated the reliability of NITs for MASLD detection and whether sex-differences in screening methods should be considered.

Cutaneous polyarteritis nodosa and pulmonary arterial hypertension: An unexpected liaison. A case report.

Background: Cutaneous polyarteritis nodosa (cPAN) is a form of medium-sized vessel necrotizing vasculitis. It is a rare, skin-limited variant of polyarteritis nodosa, characterized by dermal and subcutaneous tissue involvement. The most common findings in cPAN include digital gangrene, livedo reticularis, and tender subcutaneous nodules.

Thyroid nodule malignancy is associated with increased non-invasive hepatic fibrosis scores in metabolic subjects.

Introduction: Thyroid cancer incidence is increasing, and adiposity-related conditions are gaining space in its pathogenesis. In this study, we aimed to detect any anthropometric, biohumoral, and clinical features that might be associated with thyroid nodule malignancy, potentially representing novel non-invasive markers of thyroid cancer.

Materials And Methods: The study was conducted in a group of 142 consecutive outpatients (47 men and 95 women) who underwent fine-needle aspiration biopsy/cytology (FNAB/C) due to suspicion of malignancy from January 2018 to September 2022.

A large asymptomatic portal vein aneurysm in an old man.

Ultrasound (US) is a useful tool in diagnosis and follow-up of portal vein aneurysms (PVA). In the absence of international surgical guidelines on PVAs, US can be effectively used in follow-up of asymptomatic patients not suitable for surgery.

Analysis of hepatic stiffness after viral eradication in a population with chronic hepatitis C treated with DAAs.

Introduction And Objectives: Despite chronic hepatitis C (CHC) is still a global burden as the high morbidity and mortality, the recently approved direct-acting antivirals (DAAs) permit a very high rate of sustained virologic response (SVR) in these patients. The clinical improvement due to viral eradication is being documented, however it is not clear why a subset of patients does not benefit in terms of fibrosis regression or hepatocellular carcinoma (HCC) development. Aim of the study was to assess the hepatic stiffness regression at SVR24 and detect factors impacting stiffness course.

Gender, BMI and fasting hyperglycaemia influence Monocyte to-HDL ratio (MHR) index in metabolic subjects.

Metabolic Syndrome (MS) is characterized by a low-grade inflammatory state causing an alteration of non-invasive indexes derived from blood count, namely monocyte-to-HDL ratio (MHR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR). We analyse a population of 771 subjects (394 controls and 377 MS patients) to evaluate the best predictive index of MS. The diagnosis of MS was made according to the 2006 criteria of the International Diabetes Federation (IDF).

Hyperhomocysteinemia is an independent risk factor of atherosclerosis in patients with metabolic syndrome.

Background: Metabolic syndrome (MetS) is a clinical condition potentially promoting the development of atherosclerotic disease. To date, the clinical impact of elevated serum homocysteine (Hcy) levels in MetS is still under discussion. The aim of this cross sectional study was to evaluate the relationship between MetS and hyperhomocysteinemia and the potential role of Hcy in the pathogenesis of atherosclerotic complications of MetS.

Liver stiffness and portal blood flow modifications induced by a liquid meal consumption: pathogenetic mechanisms and clinical relevance.

Objective: The correlation between liver stiffness (LS) variations and portal blood flow (PBF) modifications induced by a standardized liquid meal consumption and the clinical relevance of this matter are two aspects not yet fully elucidated. Herein, we evaluated the variations of LS and PBF after a standardized liquid meal intake in patients with chronic liver disease.

Material And Methods: PBF and LS were determined after an overnight fasting period in 54 patients.

[Nutcracker syndrome: a difficult case of recurrent gross hematuria].

Background: The Nutcracker Syndrome (NS) is an uncommon clinical condition caused by compression and entrapment of the renal vein (LRV) as it passes through the angle between the superior mesenteric artery (SMA) and the aorta (meso-aortic angle). Intermittent macrohematuria, left peripelvic and gonadal vein varices and aspecific abdominal pain may be common manifestations of this syndrome.

Case-report: A 15-year-old white boy developed recurrent macrohaematuria in June 2002.

Haemodynamic effects of propranolol, octreotide and their combination during fasting and post-prandial splanchnic hyperaemia in patients with cirrhosis.

Background/aims: This double-blind study was designed to evaluate the haemodynamic effect of two drugs, propranolol and octreotide, and their combination in patients with cirrhosis.

Methods: Fifteen patients with cirrhosis were randomly assigned to two groups receiving either octreotide subcutaneously at 100 microg ('octreotide' group, n = 9) or propranolol orally at 40 mg followed by a subcutaneous dose of octreotide (100 microg) after 1 h ('propranolol + octreotide' group, n = 6); then, after 30 min, a standard meal was administered to both groups. The hepatic vein pressure gradient by hepatic vein catheterization, portal and superior mesenteric artery blood flow velocity, superior mesenteric artery pulsatility index by the echo-Doppler duplex system were recorded at baseline, 1 h after propranolol in the 'propranolol + octreotide' group, and in both groups 30 min after octreotide and 30 min after meal.

Octreotide blunts postprandial splanchnic hyperemia in cirrhotic patients: a double-blind randomized echo-Doppler study.

The effect of octreotide, a long-acting synthetic analog of somatostatin, on fasting and postprandial splanchnic hemodynamics was investigated in cirrhotic patients. Splanchnic hemodynamics were assessed using an echo-Doppler duplex system in a prospective, double-blind, placebo-controlled, crossover study performed on 2 separate days, 1 week apart, in 30 cirrhotic patients. Measurements of portal vein (PV) cross-sectional area (PV-A) and mean velocity (PV-V), and of superior mesenteric artery (SMA) mean velocity (SMA-V) and pulsatility index (SMA-PI) (an index of vascular resistance) were performed at baseline, 30 minutes after octreotide (200 micrograms subcutaneously) or placebo administration, and 30 and 60 minutes after the ingestion of a liquid meal.

Comparison between the effect of L-propionylcarnitine, L-acetylcarnitine and nitroglycerin in chronic peripheral arterial disease: a haemodynamic double blind echo-Doppler study.

The haemodynamic effects on the peripheral vascular bed of L-acetylcarnitine, L-propionylcarnitine, and nitroglycerin were tested by echo-Doppler in a double blind cross-over study. Eleven male patients suffering from peripheral arterial obliterative disease (PAOD) in the second stage of Fontaine's classification, and 11 matched control subjects were enrolled in the study. Each subject received one of three different treatments on each day of the study in a different order following a random assignment.

[Echo-color Doppler in the study of portal hypertension].

Color-Doppler US is currently an extremely valuable tool in the study of abdominal circulation, cirrhosis of liver and its complications, different kinds of portal hypertension, vascular/avascular liver malformations and, finally, in the evaluation of liver transplants. Moreover, its use in experimental studies has yielded good results. Even spontaneous porto-systemic shunts can be demonstrated in most cases (up to 88%).

Echo-Doppler evaluation of acute flow changes in portal hypertensive patients: flow velocity as a reliable parameter.

In order to evaluate the behavior of the portal vein cross-sectional area during changes in portal flow, two groups of subjects were analyzed in two blinded cross-over studies using echo-Doppler flowmetry. The first group (I) consisted of 21 patients with cirrhosis and 16 controls. They received a standardized meal which is known to increase portal flow.

Acute systemic and splanchnic haemodynamic effects of L-carnitine in patients with cirrhosis.

L-carnitine (L-C) is a naturally occurring substance in mammalian tissues that has recently been proposed as a therapeutic agent in hepatic encephalopathy and liver steatosis. L-C also produces some acute, non-metabolic, haemodynamic effects that have not previously been studied in patients with cirrhosis. Therefore, the authors evaluated the acute effect of i.
