Introduction: We assessed the performance of direct-acting antivirals (DAAs) in hepatitis C virus (HCV)-infected people who use drugs (PWUDs) in terms of sustained virological response (SVR) and adherence rates in comparison to a location-matched cohort of non-PWUD HCV patients., Methods: All consecutive HCV RNA-positive PWUDs were enrolled between 2015 and 2019. All subjects underwent DAA treatment according to international guidelines and then followed, at least, up to 12 weeks after the end of treatment (SVR12). The SVR and adherence to treatment was compared with that of non-PWUD HCV patients observed at hepatological units of the CLEO platform. Intention-to-treat analysis was performed., Results: A total of 1,786 PWUDs who were followed up were available for assessment. Most PWUDs (85.4%) were managed inside the specialized outpatient addiction clinics (SerDs). The overall SVR rate was 95.4%. The SerDs group achieved an SVR rate of 96.2% compared with 91.6% of the non-SerDs group (P < 0.001). Comparison with the non-SerDs group and the control HCV group showed a significant difference in the dropout rate (0.6% in the SerDs group versus 2.8% in the non-SerDs group and 1.2% in the control group; P < 0.001). At multivariate analysis, factors independently associated with SVR were use of the most recent regimens (elbasvir/grazoprevir, glecaprevir/pibrentasvir, and sofosbuvir/velpatasvir; odds ratio: 3.126; P = 0.000) and belonging to the SerDs group (odds ratio: 2.356; P = 0.002)., Discussion: The performance of DAAs in PWUD is excellent, if 2 conditions are met: (i) that the latest generation drugs are used and (ii) that the patients are managed within the SerDs., (Copyright © 2021 by The American College of Gastroenterology.)

Background: Evidence is scarce on the efficacy of long-term human albumin (HA) administration in patients with decompensated cirrhosis. The human Albumin for the treatmeNt of aScites in patients With hEpatic ciRrhosis (ANSWER) study was designed to clarify this issue., Methods: We did an investigator-initiated multicentre randomised, parallel, open-label, pragmatic trial in 33 academic and non-academic Italian hospitals. We randomly assigned patients with cirrhosis and uncomplicated ascites who were treated with anti-aldosteronic drugs (≥200 mg/day) and furosemide (≥25 mg/day) to receive either standard medical treatment (SMT) or SMT plus HA (40 g twice weekly for 2 weeks, and then 40 g weekly) for up to 18 months. The primary endpoint was 18-month mortality, evaluated as difference of events and analysis of survival time in patients included in the modified intention-to-treat and per-protocol populations. This study is registered with EudraCT, number 2008-000625-19, and ClinicalTrials.gov, number NCT01288794., Findings: From April 2, 2011, to May 27, 2015, 440 patients were randomly assigned and 431 were included in the modified intention-to-treat analysis. 38 of 218 patients died in the SMT plus HA group and 46 of 213 in the SMT group. Overall 18-month survival was significantly higher in the SMT plus HA than in the SMT group (Kaplan-Meier estimates 77% vs 66%; p=0·028), resulting in a 38% reduction in the mortality hazard ratio (0·62 [95% CI 0·40-0·95]). 46 (22%) patients in the SMT group and 49 (22%) in the SMT plus HA group had grade 3-4 non-liver related adverse events., Interpretation: In this trial, long-term HA administration prolongs overall survival and might act as a disease modifying treatment in patients with decompensated cirrhosis., Funding: Italian Medicine Agency., (Copyright © 2018 Elsevier Ltd.

Approximately 30% of patients with chronic HCV infection have persistently normal ALT levels. Although formerly referred to as 'healthy' or 'asymptomatic' HCV carriers, and thus historically excluded from antiviral treatment, it has now become clear that the majority of these patients have some degree of histological liver damage that may be significant in up to 20% of cases and might progress towards a more severe degree of liver fibrosis. A significant proportion of patients experience periods of increased serum ALT associated with enhanced disease progression. However, controversies still exist in clinical practice regarding the definition of 'persistent' ALT normality, the virological and histological features of these subjects, the need for liver biopsy, the role of noninvasive tools for the assessment of liver fibrosis, the natural history and the usefulness of antiviral treatment. The advent of new therapeutic options (pegylated interferon plus ribavirin) has shifted treatment targets towards the eradication of underlying infection, with therapy decision based on age, severity of disease and likelihood of response rather than on aminotransferase levels. This review is aimed at approaching the main unresolved issues on this topic, trying to give evidence-based answers to the more frequently asked questions from patients and their physicians., (© 2011 Blackwell Publishing Ltd.)

Rapid virological response (RVR) is now considered the strongest predictor of sustained virological response (SVR) in patients with HCV undergoing antiviral treatment, and thus, shorter antiviral treatment for these patients has been suggested. However, no data exist on the predictive value of RVR in HCV carriers with normal ALT values. A total of 137 patients with persistently normal ALT treated with peginterferon alfa 2a and ribavirin were studied. Fifteen patients dropped out early because of side effects, and in 10 patients with HCV-1 treatment was discontinued because of lack of early virological response (EVR). RVR was observed in 68% of the patients (42% patients with HCV-1, 90% HCV-2 and 64% HCV-3). An end-of-treatment response was observed in 86% of the patients (68% HCV-1, 100% HCV-2 and 91% HCV-3). SVR was maintained in 91 patients (46% HCV-1, 97% HCV-2 and 82% HCV-3). Overall, 92% patients with rapid response did obtain HCV eradication vs only 38% of those without rapid response. HCV-1 patients with baseline HCV RNA <400×10(3) IU/mL were more likely to achieve RVR and SVR than those with higher HCV RNA levels. We conclude that patients with genotype 1 and normal ALT who achieve HCV RNA negativity at week 4 may have a higher probability of eradicating their infection. Because of the concomitant favourable demographic and virological features often found in this particular subset of patients, the duration of therapy in these people might be shortened in the case of RVR. Persistently normal alanine aminotransferase levels patients with genotype 2 or 3 have a high chance of achieving SVR, so retesting of HCV RNA during treatment may have no additional practical value in these subjects., (© 2010 Blackwell Publishing Ltd.)

Approximately 30% of patients with chronic HCV infection show persistently normal ALT levels. Although formerly referred to as 'healthy' or 'asymptomatic' HCV carriers, and thus historically excluded from antiviral treatment, it has now become clear that the majority of these patients have some degree of histological liver damage that may be significant in up to 20% of patients and might progress toward a more severe degree of liver fibrosis. A significant proportion of patients (> or =20%) experience periods of increased serum ALT (flare) associated with enhanced disease progression. However, controversies still exist in clinical practice regarding the definition of 'persistent' ALT normality, the virological and histological features of these subjects, the need for liver biopsy, the role of non invasive tools for the assessment of liver fibrosis (transient hepatic elastography, fibroscan), and the natural history and optimal management of chronic hepatitis C with normal ALT. The advent of new therapeutic options (pegylated interferons plus ribavirin) has shifted treatment targets toward eradication of underlying infection, with therapy decision based on age, severity of disease and likelihood of response rather than on aminotransferase levels. This review does approach the main unresolved issues on this topic in the form of a dialog between a hepatologist and a patient with HCV infection but normal alanine aminotransferase levels, trying to give evidence-based answers to the more frequently asked questions from patients and their physicians., (Copyright 2009 Elsevier B.V.

Background and Aim: Abnormal serum tissue polypeptide antigen (TPA) values are commonly found in patients with chronic liver damage and liver cirrhosis even in the absence of malignancies. The aim of this study was to compare serum TPA levels in patients with cirrhosis, to examine correlations between TPA levels and the degree of portal hypertension, and to evaluate TPA concentrations in paired hepatic and peripheral blood samples., Methods: A total of 128 patients with chronic liver disease of various severity were studied prospectively. TPA concentrations in hepatic vein and peripheral blood were determined, and Hepatic Vein Pressure Gradient (HVPG) was measured., Results: TPA levels were significantly higher in patients with cirrhosis than in those with chronic hepatitis, and in systemic circulation than in hepatic vein blood. Peripheral but not hepatic TPA levels did correlate with the HVPG. Subjects with clinically significant portal hypertension (HVPG > 10 mmHg) showed significantly higher peripheral TPA levels than those with HVPG < 10 mmHg., Conclusions: Our data suggest that the increased TPA levels observed in cirrhotic patients and the high systemic-to-hepatic blood TPA gradient are probably due to the presence of portal-systemic shunts rather than to hepatic necro-inflammatory activity. In clinical practice, TPA determination could help us to identify and to follow up cirrhotic patients with more severe portal hypertension.

Background/aims: To evaluate, in clinical practice, the efficacy and safety of combined antiviral treatment in hepatitis C virus (HCV) carriers with normal alanine aminotransferase (ALT) levels., Methods: Eighty-eight HCV carriers with persistently normal ALT levels were enrolled. All patients received peginterferon (PEG-IFN) alpha-2a 180 microg once weekly plus ribavirin (RBV) 800 mg/day for 24 weeks (HCV-2 and -3) or 1000-1200 mg/day for 48 weeks (HCV-1)., Results: Rapid virological response (RVR) was seen in 66/88 patients (75%): 19/32 HCV-1 (59%), 40/46 HCV-2 (87%) and 7/10 HCV-3 patients. Younger patients, leaner subjects and patients with non-1 genotype or lower baseline HCV RNA levels were more likely to achieve an RVR. Sustained virological response (SVR) was seen in 69/88 patients (78%): 20/32 HCV-1 patients (62%), 41/46 HCV-2 patients (89%) and 8/10 (80%) HCV-3 patients. The overall SVR rate was 88% in patients with RVR (58/66) and 50% in those without RVR., Conclusions: The combination of PEG-IFN alpha-2a and RBV produces, in patients with normal ALT, virological response rates that are comparable or even higher than those obtained in patients with elevated ALT levels. Thus, we suggest that in selected cases immediate therapy might be preferred to a 'wait-and-see' policy.

Approximately 30% of patients with chronic HCV infection show persistently normal alanine aminotransferase levels (PNAL). The prevalence of HCV carriers with normal liver seems to be very low (less than 15-20%). Liver disease is usually minimal/mild and fibrosis is generally absent or minimal, although the association of normal alanine aminotransferase (ALT) with cirrhosis or with liver cancer has been reported. In all studies, liver histology was, on average, significantly less severe in subjects with PNAL than with abnormal ALT. Although the majority of data seem to show that HCV carriers with normal ALT have mild and stable disease, with a favourable prognosis, several studies reported a significant progression of fibrosis in approximately 20-30% of the patients with ALT normality, and the development of HCC in some cases has been described, despite persistent ALT normality. Sudden worsening of disease with ALT increase and histological deterioration has been described after up to 15 years of follow-up, in particular in patients harboring genotype 2. As to antiviral treatment, it has been clearly stated that it no longer seems reasonable to affirm that sustained response rates for patients with normal ALT levels are any different than those for patients with elevated ALT levels when the combination of pegylated interferon (IFN) and ribavirin is used. The issue at hand is whether or not patients with mild disease should be treated. There are numerous other factors which impact on this decision, including genotype, histology, patients motivation, symptoms, co-morbid illness, and the age of the patient.

Background and Aims: To evaluate whether the hepatic venous pressure gradient (HVPG) differs between cirrhotic patients with severe portal hypertensive gastropathy (PHG) and those with mild or absent PHG., Methods: 59 cirrhotic patients with portal hypertension underwent hepatic vein catheterisation. 44 patients (76%) had PHG (16 mild and 28 severe)., Setting: tertiary care setting (Liver Unit, Internal Medicine)., Results: HVPG values did not differ between the patients without PHG (21.6 +/- 10.1 mmHg) and those with PHG (18.6 +/- 9.1 mmHg), nor between those with mild (19.3 +/- 4.3 mmHg) or severe PHG (17.7 +/- 4.6 mmHg; p = 0.26). The overall prevalence of PHG and the proportion of patients with severe PHG did not differ regarding the Child Pugh classification. The etiology of the cirrhosis did not influence the HVPG. No correlations were found between HVPG values and Child Pugh score, age, platelet count, prothrombin time, bilirubin levels and ALT values. The HVPG did not differ between patients with small, medium or large esophageal varices, nor between subjects with or without gastric varices., Conclusions: Our data show that PHG does not correlate with the degree of portal pressure, and that the prevalence and the severity of this condition are not influenced by the severity of underlying liver disease or by the size of varices.

Several extrahepatic manifestations have been reported in the natural history of hepatitis C virus infection (HCV). Up to 40-74% of patients infected with HCV might develop at least one extrahepatic manifestation during the course of their disease. Mixed Cryoglobulinemia (MC) is the most known and studied syndrome associated with HCV infection. It is a systemic vasculitis that may involve the skin, kidney and nervous system. A frequent reported association is that between HCV infection and non-Hodgkin lymphoma. The cryoglobulinemia may be the intermediary disorder, in fact some persistent forms of cyoglobulinemia can switch over to a more aggressive haematologic disorder. As compared to cutaneous vasculitis described in MC, HCV infection has been associated with dermatological disorders such as porphyria cutanea tarda and lichen planus. Thyroid disease (usually hypothyroidism) is commonly seen in people with HCV. Up to 25% have thyroid antibodies. Several studies described a correlation between HCV and lympho-cytic sialoadenitis, similar to sialoadenitis associated with idiopathic Sjögren syndrome, but we can define as "pseudo- Sjögren syndrome" the one associated with HCV infection, because it shows several differences in the idiopathic form. In the course of chronic HCV infection, a common obser-vation are rheumatological symptoms such as polyarthritis. The clinical pattern of joint involvement in the course of HCV infection varies from a rheumatoid arthritis-like form (very rare), to a non erosive oligoarthritis involving the large-sized and middle joints.

Surveillance of patients with HCV-related chronic liver disease (CHC) not on antiviral therapy is mandatory, because of the risk of worsening of the disease and progression to cirrhosis and its lethal complications. Unfortunately, data from the literature are scarce, and sometimes there are differences among experts and discrepancies between recommendations. Furthermore, the wide range of diagnostic tests and the continuous development of new diagnostic tools not rarely results in expensive, redundant and not justified surveillance programs. The identification of the optimal frequency of follow-ups constitutes another source of difficulties for the physicians. The purpose of this article is to provide practicing physicians with published criteria for performing a cost-effective and adequate surveillance program for patients with CHC not on antiviral treatment. On the basis of randomized controlled trials (RCTs), metanalysis, and international guide-lines and Consensus Conference statements we have attempted to outline a cost-effective surveillance program for HCV carriers with normal aminotransferases (ALT), for responders to previous interferon (IFN) treatment and for patients with CHC non-eligible for antiviral therapy. This surveillance strategy relies upon the judicious use of un-expensive and widely available tests.

The aim of this study was to confirm the clinical efficacy of oxerutins by evaluation of venous parietal tone and microvascular perfusion in a double-blind, randomized, placebo-controlled study. The study included 60 patients. Venous tone was evaluated by air-plethysmography (APG) in patients with venous insufficiency (CVI). Forty patients were treated with oxerutins and 20 with placebo for 4 weeks. The dose of the first 2 weeks was higher than that of the following 2 weeks. The age range was between 18 and 65 years. Randomized patients received treatment (oxerutins or placebo) according to the grade of CVI. Patients with grade I CVI received 2 g/day in the first 2 weeks of treatment and 1 g/day in the following weeks. Patients with grade II CVI received 3 g/day in the first 2 weeks and 2 g/day in the following 2 weeks. Visits were scheduled at baseline time (visit 1), at 2 weeks (visit 2) and at 4 weeks (visit 3). They were assessed with the following: (1) APG; (2) light reflection rheography (LRR); (3) capillaroscopy; (4) liquid crystals thermography. CVI signs/symptoms--heavy legs, edema, paresthesia, and cramps--were evaluated following a 4-point rating scale (0 = no symptom; 3 = severe symptoms). At visit 3 a final opinion on efficacy was provided by both patients and investigators, based on a 4-point scale (none, fairly good, good, excellent). The two groups were homogeneous for age, sex, and clinical distribution. The changes in venous capacity, were significant (p<0.01) in the oxerutins group at visits 2 and 3; values in the placebo group remained unchanged. The changes in LRR were significant in the treatment group at visits 2 (p<0.05) and 3 (p<0.01); values in the placebo group remained unchanged. Changes in temperature were significant in the oxerutins group at visits 2 (p<0.05) and 3 (p<0.01); changes in the placebo group were not significant at the end of the study. Capillaroscopy showed an improvement in patients treated with oxerutins. The results of the analysis of signs/symptoms favored active treatment. The overall effects of oxerutins were significantly better than the effects of placebo. Considering both noninvasive tests and clinical evaluation, oxerutins is effective in controlling chronic venous hypertension, without side effect, and with good tolerability.

Purpose: Partially hydrolyzed guar gum (PHGG) is a water-soluble dietary fiber, possessing non-gelling properties. The objective of this clinical experience was to evaluate the progress of symptoms and the modifications in the frequency of evacuation in subjects affected by IBS and regularly taking PHGG., Patients and Methods: The group was made up of 134 out-patients of both sexes, average age 43.12, suffering from IBS, both obese and of normal weigh, with a mean number of weekly evacuations between 2 and 35. The subjects, divided in 2 groups on the basis of Body Mass Index (BMI), were submitted for 24 weeks to a balanced, low or normal calorie diet supplemented by 5 g a day of PHGG. The following information was gathered: number of weekly evacuation, typical symptoms of IBS, cholesterol, triglycerides and glucose levels. In a few subjects (n. = 34) also the plasmatic electrolyte levels, before and during PHGG intake, were evaluated., Results: Both groups showed positive results in the evacuation frequency (p < 0.01 at 12th week) and a decrease, after 3 weeks of PHGG intake, in frequency of IBS symptoms such as flatulence (-55.6%), abdominal tension (-4.7%) and abdominal spasm (-35%). On the other hand an increased number of subjects showed normal levels of cholesterol (+12.2%), lipids (+26.9%) and glucose (+16%). Concentrations of plasmatic electrolytes didn't change during PHGG intake, except for a marked increase of selenium levels, compared to pre-intake levels., Conclusions: The observations obtained from this clinical experience reassert that dietary fiber supplementation is useful in cases of altered intestinal motility. PHGG, due to its water-solubility and non-gelling properties, can be useful also in IBS.

Objective: ACE inhibitors and calcium antagonists may favorably affect serum lipids and glucose metabolism. The primary aim of the Fosinopril Versus Amlodipine Cardiovascular Events Randomized Trial (FACET) was to compare the effects of fosinopril and amlodipine on serum lipids and diabetes control in NIDDM patients with hypertension. Prospectively defined cardiovascular events were assessed as secondary outcomes., Research Design and Methods: Inclusion criteria included a diagnosis of NIDDM and hypertension (systolic blood pressure of > 140 mmHg or diastolic blood pressure of > 90 mmHg). Exclusion criteria included a history of coronary heart disease or stroke, serum creatinine > 1.5 mg/dl, albuminuria > 40 micrograms/min, and use of lipid-lowering drugs, aspirin, or antihypertensive agents other than beta-blockers or diuretics. A total of 380 hypertensive diabetics were randomly assigned to open-label fosinopril (20 mg/day) or amlodipine (10 mg/day) and followed for up to 3.5 years. If blood pressure was not controlled, the other study drug was added., Results: Both treatments were effective in lowering blood pressure. At the end of follow-up, between the two groups there was no significant difference in total serum cholesterol, HDL cholesterol, HbA1c, fasting serum glucose, or plasma insulin. The patients receiving fosinopril had a significantly lower risk of the combined outcome of acute myocardial infarction, stroke, or hospitalized angina than those receiving amlodipine (14/189 vs. 27/191; hazards ratio = 0.49, 95% CI = 0.26-0.95)., Conclusions: Fosinopril and amlodipine had similar effects on biochemical measures, but the patients randomized to fosinopril had a significantly lower risk of major vascular events, compared with the patients randomized to amlodipine.
