Measurement of Gamma Glutamyl Transferase to Determine Risk of Liver Transplantation or Death in Patients With Primary Biliary Cholangitis.

BACKGROUND & AIMS: Gamma-glutamyltransferase (GGT) is a serum marker of cholestasis. We investigated whether serum level of GGT is a prognostic marker for patients with primary biliary cholangitis (PBC). METHODS: We analyzed data from patients with PBC from the Global PBC Study Group, comprising 14 centers in Europe and North America. We obtained measurements of serum GGT at baseline and time points after treatment. We used Cox model hazard ratios to evaluate the association between GGT and clinical outcomes, including liver transplantation and liver-related death. RESULTS: Of the 2129 patients included in our analysis, 281 (13%) had a liver-related clinical endpoint. Mean age at diagnosis was 53 years and 91% of patients were female patients. We found a correlation between serum levels of GGT and alkaline phosphatase (ALP) (r = 0.71). Based on data collected at baseline and yearly for up to 5 years, higher serum levels of GGT were associated with lower hazard for transplant-free survival. Serum level of GGT at 12 months after treatment higher than 3.2-fold the upper limit of normal (ULN) identified patients who required liver transplantation or with liver-related death at 10 years with an area under the receiver operating characteristic curve of 0.70. The risk of liver transplantation or liver-related death in patients with serum level of GGT above 3.2-fold the ULN, despite level of ALP lower than 1.5-fold the ULN, was higher compared to patients with level of GGT lower than 3.2-fold the ULN and level of ALP lower than 1.5-fold the ULN (P < .05). Including information on level of GGT increased the prognostic value of the Globe score. CONCLUSIONS: Serum level of GGT can be used to identify patients with PBC at risk for liver transplantation or death, and increase the prognostic value of ALP measurement. Our findings support the use of GGT as primary clinical endpoint in clinical trials. In patients with low serum level of ALP, a high level of GGT identifies those who might require treatment of metabolic disorders or PBC treatment escalation.

CA.ME.LI.A. An epidemiological study on the prevalence of CArdiovascular, MEtabolic, LIver and Autoimmune diseases in Northern Italy.

BACKGROUND AND AIMS: CA.ME.LI.A (CArdiovascular risks, MEtabolic syndrome, LIver and Autoimmune disease) is a cross-sectional, epidemiological study performed between 2009-2011 in Abbiategrasso (Milan, Italy) to estimate the prevalence of cardiovascular risk factors, metabolic syndrome, liver and autoimmune diseases in the general adult population. This report focuses on the description and presentation of baseline characteristics of the population. METHODS AND RESULTS: Citizens were randomly selected from the city electoral registers (n = 30903), yielding a sample of 2554 subjects (M = 1257, F = 1297; age, 47 ± 15 yrs; range 18-77 yrs). Men had higher prevalence of overweight or obesity (60.8% vs 41.6%; p < 0.0001) and greater thickness of visceral adipose tissue (40 ± 19 vs 27 ± 17 mm; p < 0.0001); no gender difference was found in subcutaneous adipose tissue thickness. Men also showed higher levels of serum triglycerides, γ-GT, fasting blood glucose, insulin and Homa-IR Index, while HDL, CRP, and prevalence of elevated (>5.0 mg/L) CRP were lower. Compared to normal weight men, risk-ratio (RR) of CRP elevation was 1.32 (ns) in overweight and 2.68 (p < 0.0001) in obese subjects. The corresponding figures in females were 2.68 (p < 0.0001) and 5.18 (p < 0.0001). Metabolic syndrome was more frequent in men (32.7% vs 14.5%; RR: 2.24, p < 0.0001). Interadventitia common carotid artery diameter was higher in men and increased with age and BMI. CONCLUSIONS: The present study reports on the overall characteristics of a large population from Northern Italy. It aims to identify the associations among cardiovascular risk factors to prevent their development and progression, improve healthy lifestyle and identify subjects liable to pharmacological interventions.

Modeling cost-effectiveness and health gains of a "universal" versus "prioritized" hepatitis C virus treatment policy in a real-life cohort.

We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virus-infected patients: policy 1, "universal," treat all patients, regardless of fibrosis stage; policy 2, treat only "prioritized" patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virus-infected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were used to evaluate the policies' cost-effectiveness. The patients' age and fibrosis stage, assumed DAA treatment cost of €15,000/patient, and the Italian liver disease costs were used to evaluate quality-adjusted life-years (QALY) and incremental cost-effectiveness ratios (ICER) of policy 1 versus policy 2. To generalize the results, a European scenario analysis was performed, resampling the study population, using the mean European country-specific health states costs and mean treatment cost of €30,000. For the Italian base-case analysis, the cost-effective ICER obtained using policy 1 was €8,775/QALY. ICERs remained cost-effective in 94%-97% of the 10,000 probabilistic simulations. For the European treatment scenario the ICER obtained using policy 1 was €19,541.75/QALY. ICER was sensitive to variations in DAA costs, in the utility value of patients in fibrosis stages F0-F3 post-sustained virological response, and in the transition probabilities from F0 to F3. The ICERs decrease with decreasing DAA prices, becoming cost-saving for the base price (€15,000) discounts of at least 75% applied in patients with F0-F2 fibrosis. CONCLUSION: Extending hepatitis C virus treatment to patients in any fibrosis stage improves health outcomes and is cost-effective; cost-effectiveness significantly increases when lowering treatment prices in early fibrosis stages.

Forecasting Hepatitis C liver disease burden on real-life data. Does the hidden iceberg matter to reach the elimination goals?

BACKGROUND & AIMS: Advances in direct-acting antiviral treatment of HCV have reinvigorated public health initiatives aimed at identifying affected individuals. We evaluated the possible impact of only diagnosed and linked-to-care individuals on overall HCV burden estimates and identified a possible strategy to achieve the WHO targets by 2030. METHODS: Using a modelling approach grounded in Italian real-life data of diagnosed and treated patients, different linkage-to-care scenarios were built to evaluate potential strategies in achieving the HCV elimination goals. RESULTS: Under the 40% linked-to-care scenario, viraemic burden would decline (60%); however, eligible patients to treat will be depleted by 2025. Increased case finding through a targeted screening strategy in 1948-1978 birth cohorts could supplement the pool of diagnosed patients by finding 75% of F0-F3 cases. Under the 60% linked-to-care scenario, viraemic infections would decline by 70% by 2030 but the patients eligible for treatment will run out by 2028. If treatment is to be maintained, a screening strategy focusing on 1958-1978 birth cohorts could capture 55% of F0-F3 individuals. Under the 80% linked-to-care scenario, screening limited in 1968-1978 birth cohorts could sustain treatment at levels required to achieve the HCV elimination goals. CONCLUSION: In Italy, which is an HCV endemic country, the eligible pool of patients to treat will run out between 2025 and 2028. To maintain the treatment rate and achieve the HCV elimination goals, increased case finding in targeted, high prevalence groups is required.

Multiple target tissue effects of GLP-1 analogues on non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH).

Accumulating experimental and clinical evidences over the last decade indicate that GLP-1 analogues have a series of central nervous system and peripheral target tissues actions which are able to significantly influence the liver metabolism. GLP-1 analogues pleiotropic effects proved to be efficacious in T2DM subjects not only reducing liver steatosis and ameliorating NAFLD and NASH, but also in lowering plasma glucose and liver inflammation, improving cardiac function and protecting from kidney dysfunction. While the experimental and clinical data are robust, the precise mechanisms of action potentially involved in these protective multi-target effects need further investigation. Here we present a systematic review of the most recent literature data on the multi-target effects of GLP-1 analogues on the liver, on adipose and muscular tissue and on the nervous system, all capable of influencing significant aspects of the fatty liver disease physiopathology. From this analysis, we can conclude that the multi-target beneficial action of the GLP-1 analogues could explain the positive effects observed in animal and human models on progression of NAFLD to NASH.

Long-term outcome of laparoscopic ablation therapies for unresectable hepatocellular carcinoma: a single European center experience of 426 patients.

BACKGROUND: Radiofrequency ablation (RFA) is widely used as a first-line option in patients with hepatocellular carcinoma (HCC). However, since percutaneous approach of RFA may be, in some cases, unfeasible by the tumor size and its location, laparoscopic ablation therapies (LATs) were used as an alternative. Objective of the present study was to assess the efficacy of laparoscopic ultrasound examination in addition to LATs in the treatment of HCC in patients not eligible for percutaneous RFA or surgical resection. METHODS: Four hundred and twenty-six patients who underwent LATs were analyzed. Laparoscopic approach was offered to patients fulfilling at least one of the following criteria: (a) patients with a single nodule or up to three nodules smaller than 3 cm not suitable for liver transplantation or not eligible for HR because of severe portal hypertension, impaired liver function, or coexistent comorbidities; (b) patients not suitable for percutaneous RFA because of inconvenient tumor location; and (c) short-term recurrence of HCC (<3 months). RESULTS: Technical success was achieved in one session in 396 patients (93 %). One-month mortality and morbidity rates were 0.23 % (1 patient) and 25 % (106 patients), respectively. During a median follow-up of 37.2 months (range 2-193) in the remaining 425 patients, 276 (65 %) developed intra-hepatic recurrence: It appeared as a local tumor progression in 65 cases (15 %). Patients median survival was 39 months (95 % CI 34.8-47.2), while overall survivals at 1, 3, and 5 years were 88, 55, and 34 %, respectively. CONCLUSIONS: In the treatment of HCC, LATs proved to be a safe and effective technique, as they permit to treat with low-morbidity-rate lesions not manageable by percutaneous approach. Moreover, they allow achieving a more accurate staging of the disease in one-fifth of patients, thus better redefining the prognosis of such individuals.

Interleukin-28B genetic variants in untreated Italian HCV-infected patients: a multicentre study.

BACKGROUND & AIMS: Different prevalence of favourable IL28BCC genotype have been reported in studies performed in different countries around the world. Data on distribution of IL28B genotypes in healthy Italian subjects are lacking. METHODS: Studies on prospectively collected untreated chronic HCV-infected Italian patients led to conflicting results. To investigate the prevalence of IL28B genotypes in untreated HCV-infected patients and in subjects able to clear HCV, and to compare them to the prevalence registered in healthy Italian controls. To evaluate IL28B prevalence across different HCV genotypes. RESULTS: IL28BCC was observed in 30.9% of chronic HCV patients, in 71.0% of subjects able to clear HCV infection and in 41.6% of the Italian controls. The frequency of IL28BCC was higher in HCV genotype 2 and 3 than in 1 (38.3 vs. 28.2) (P = 0.02). Levels of ALT higher in IL28BCC than in non-CC were observed regardless of HCV genotypes (P = 0.0014). CONCLUSIONS: IL28BCC frequencies progressively decline from subjects with spontaneous HCV clearance to normal non-infected subjects and to chronically infected. This study suggests that patients with IL28BCC, if genotype 1, are able to clear HCV more often than if genotype 2 and 3 infected, and that CC genotype is associated with higher grade of necro-inflammation.

Study of corneal copper deposits in Wilson's disease by in vivo confocal microscopy.

PURPOSE: To study corneal copper deposits in Wilson's disease (WD) patients by traditional biomicroscopy and in vivo laser scanning confocal microscopy (LSCM). METHODS: Twenty WD patients and 20 matched controls underwent an ophthalmic examination in one eye randomly chosen, including slit lamp biomicroscopy with Goldmann's three-mirror contact lens examination and LSCM, in order to evaluate copper deposits in the peripheral cornea. RESULTS: No control subjects had corneal changes at both traditional biomicroscopy and LSCM. Only 25% of WD patients had detectable slit lamp changes, compared with 75% with LSCM examination. All cases detected by slit lamp were detected by LSCM. A significant correlation (p < 0.01) was found between deposit intensity at LSCM and daily urinary copper excretion. CONCLUSION: LSCM could detect copper deposition in WD corneas in more patients than traditional examination; it may therefore provide important information in cases of suspected WD diagnosis.

Hepatic resection for "BCLC stage A" hepatocellular carcinoma. The prognostic role of alpha-fetoprotein.

BACKGROUND: Our aim was to assess the capability of Barcelona Clinic Liver Cancer (BCLC) staging system in allocating stage A patients to hepatic resection (HR) and the effect on survival. METHODS: We enrolled 132 patients with hepatocellular carcinoma (HCC) amenable to HR. All patients underwent ultrasound (US)-guided anatomical resection (≤2 segments) and then postoperative results were evaluated. RESULTS: Results showed 95% of patients were Child A, 49% in BCLC A1, 21% in A2, 6% in A3, and 24% in A4. No 30-day mortality occurred. Overall survival got worse from A1 to A4 (P = 0.0271), while no differences were found in Childs A patients with or without portal hypertension (P = 0.1674). Multivariate analysis (Cox model) shows that only AFP (<20 ng/ml) was an independent predictor of survival: If the AFP is incorporated in BCLC staging system (all A1 and A2 patients with abnormal AFP levels were included in A3 subgroup), 5-year survival rate including normal AFP for A1 was 57% and for A2 was 65%, whereas the survival rates impaired in the worst candidates (5-year survival rate including AFP abnormal for A3 and A4 was 36%; P = 0.002). So, introducing AFP in BCLC classification it is possible to simplify the algorithm in only 2 classes, well-separated in survival curves (class 1 [AFP-]: 60%; class 2 [AFP+]: 37%; P = 0.0001). CONCLUSION: Our experience stressed the high value of BCLC system in staging of patients with HCC, but underlined that in selected patients (normal AFP) even A2 group may benefit from HR with a good survival.

Recurrent hepatocellular carcinoma successfully treated with laparoscopic thermal ablation.

BACKGROUND: Aggressive treatment of intrahepatic recurrence of hepatocellular carcinoma (HCC) increases patients' survival. This study aimed to evaluate laparoscopic thermal ablation (TA) in the treatment of intrahepatic HCC recurrences. METHODS: A retrospective analysis was performed on 88 patients (REC group) who underwent laparoscopic TA after prior TA (66 patients.) or partial hepatic resection (HR) (22 patients) as initial local treatment. Another 170 patients with primary HCC tumors (PRIM group) were regarded as the control group. RESULTS: The postoperative morbidity rates were similar for the patients with prior TA (18%) and those with prior HR (21%) (nonsignificant difference [NS]). The overall survival rates were not significantly different between the two groups (3-year survival rates of 59 and 78%, respectively; P = 0.1662). Moreover, the disease-free survival (DFS) rates did not differ significantly between the patients with prior TA and those with prior HR (3-year DFS of 21 and 8%, respectively; P = 0.1911). The incidences of morbidity in the whole REC (21%) and PRIM (20%) groups were similar (P = NS), and no mortality occurred in either group (0%). The cumulative 3-year survival rate was 63% in the REC group and 59% in the PRIM group (P = 0.5739), whereas the 3-year DFS rate was 17% in the REC group and 22% in the PRIM group (P = 0.5266). CONCLUSION: Laparoscopic TA can be performed safely and may be effective for intrahepatic HCC recurrence after prior TA or HR. It leads to survival and DFS rates similar to those obtained using laparoscopic TA for primary HCC without increasing morbidity. Laparoscopic TA could be proposed as first-line treatment of intrahepatic HCC recurrence for selected patients.

Multicentre, retrospective study to assess long-term outcomes of chelator based treatment with trientine in Wilson disease patients withdrawn from therapy with d -penicillamine.

OBJECTIVES: Trientine dihydrochloride (TETA-2HCl) has been used for the treatment of Wilson disease for over 30 years. The current study was designed to systematically evaluate existing data to further define the long-term outcome of the efficacy and tolerability of TETA-2HCl in Wilson disease patients. METHODS: Medical records of 77 Wilson disease patients were reviewed to collect data on hepatic and neurologic symptoms, copper (Cu) homeostasis and adverse events. Data were collected for 48 months after initiation of TETA-2HCl after withdrawal of D-penicillamine treatment. RESULTS: Mean duration of TETA-2HCl treatment was 8 years (range 5 months-32.5 years). Over the course of TETA-2HCl treatment, 35% of patients had no hepatic symptoms whereas in 49.4% of patients, hepatic symptoms improved. They remained unchanged in 10.4% of patients and worsened in 5.2% of patients. No patients progressed to acute hepatic failure or necessity of a liver transplant. During TETA-2HCl treatment, 46.7% of patients had no neurologic symptoms; in 14.3% of patients, neurologic symptoms improved whereas in 36.4% of patients, they remained stable and worsened in 2.6% of patients. During the evaluation period, 12 patients discontinued TETA-2HCl treatment due to: anemia ( N = 1), inadequate hepatic response ( N = 2), switch to zinc treatment ( N = 8) and patient's decision to withdraw from treatment ( N = 1). Treatment-emergent adverse events were reported by 24.7% of the patients of which gastrointestinal disorders (9.1%) and nervous system disorders (5.2%) were most reported. CONCLUSIONS: TETA-2HCl is well-tolerated and effective in Wilson disease patients following the withdrawal of treatment with D-penicillamine. ClinicalTrials.govIdentifier : NCT02426905.

Trientine tetrahydrochloride versus penicillamine for maintenance therapy in Wilson disease (CHELATE): a randomised, open-label, non-inferiority, phase 3 trial.

BACKGROUND: Wilson disease is an inherited disorder of copper transport. Whereas penicillamine is used therapeutically to re-establish copper balance, trientine is indicated for patients with penicillamine intolerance. We aimed to compare penicillamine with trientine tetrahydrochloride (TETA4) for maintenance therapy in patients with Wilson disease. METHODS: We conducted a randomised, open-label, non-inferiority, phase 3 trial at 15 health-care centres across nine countries (patients were recruited from 13 of these health-care centres across Brazil, Europe, and the USA). We enrolled patients aged 18-75 years with stable Wilson disease who were treated for at least 1 year with penicillamine. Patients entered a 12-week period to determine stability through clinical assessment by site investigators and predefined thresholds for serum non-caeruloplasmin-bound copper (NCC; by an exchangeable copper assay; 25-150 µg/L), 24 h urinary copper excretion (100-900 µg/24 h), and alanine aminotransferase (ALT; <2 × upper limit of normal). Stable patients were randomly assigned (1:1) to continue receiving the maintenance twice daily dose of oral penicillamine or switched mg-for-mg to oral TETA4 centrally with a web-based system using minimisation. The primary endpoint, assessed 24 weeks after randomisation, was NCC by speciation assay. The non-inferiority margin of mean difference in NCC by speciation assay was -50 µg/L, as estimated by a general linear model for repeated visits, adjusted for baseline values. Further data on safety and efficacy were collected during a 24-week extension period. Data were analysed using an intention-to-treat approach. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, NCT03539952 (active, not recruiting). FINDINGS: Between June 4, 2018, and March 10, 2020, 77 patients were screened. 53 patients were randomly assigned (27 to the penicillamine group and 26 to the TETA4 group). After 24 weeks, the mean difference in serum NCC by speciation assay between the penicillamine group and TETA4 group was -9·1 µg/L (95% CI -24·2 to 6·1), with the lower limit of the 95% CI within the defined non-inferiority margin. At 24 weeks, urinary copper excretion was lower with TETA4 than with penicillamine (mean difference 237·5 µg/24 h (99% CI 115·6 to 359·4). At 48 weeks, TETA4 remained non-inferior to penicillamine in terms of NCC by speciation assay (mean difference NCC -15·5 µg/L [95% CI -34·5 to 3·6]). Urinary copper excretion at 48 weeks remained in the expected range for well treated patients in both study groups, and the mean difference (124·8 µg/24 h [99% CI -37·6 to 287·1]) was not significantly different. At 24 weeks and 48 weeks, masked clinical adjudication of stability assessed by three independent clinicians confirmed clinical stability (100%) of all participants, in agreement with the stability seen with the NCC by speciation assay. There were no notable changes in either the Clinical Global Impression of Change or Unified Wilson Disease Rating Scale (neurological assessment) from baseline (pre-randomisation) at weeks 24 and 48. The mean change in serum total copper from baseline to 24 weeks was 17·6 µg/L (99% CI -9·5 to 44·7) with penicillamine and -6·3 µg/L (-34·7 to 22·1) with TETA4, and the mean change in serum total caeruloplasmin from baseline to 24 weeks was 1·8 mg/L (-19·2 to 22·8) with penicillamine and -2·2 mg/L (-6·1 to 1·7) with TETA4. All liver enzymes were similar at 24 weeks and 48 weeks, with the exception of elevated ALT concentration at 48 weeks for patients in the TETA4 group. Penicillamine was associated with three post-randomisation serious adverse events (leukopenia, cholangiocarcinoma, and hepatocellular cancer); none were reported for TETA4. The most common treatment-emergent adverse events were headache for penicillamine (five [19%] of 27 patients vs two [8%] of 26) and abdominal pain for TETA4 (one [4%] vs four [15%]); all treatment-emergent adverse events resolved and were mild to moderate. One patient developed a rash with TETA4 that resolved on discontinuation of therapy. INTERPRETATION: The efficacy of TETA4 as oral maintenance therapy was non-inferior to penicillamine and well tolerated in adults with Wilson disease. FUNDING: Orphalan.

Directly acting antivirals are safe and effective in HCV positive patients aged 80 years and older: a multicenter real-life study.

Background: Treatment of chronic Hepatitis C with directly acting antivirals (DAAs) can bring to sustained virologic response (SVR) in approximately 95% of patients. Efficacy and safety of DAAs in aging patients has not been widely analyzed. We aimed to determine safety and efficacy of DAA-based regimens in a cohort of elderly patients in a real-life setting.Research Design and Methods: We retrospectively investigated safety and efficacy of DAAs in HCV patients of 80 years or older treated in three Hepatology Units.Results and Expert opinion: During the study period, 170 patients older than 80 years received DAAs. Their mean age was 82,3 years. The predominant HCV genotype was 1 (100 patients, 59%). Among the 93 cirrhotic patients (54,7%), 18 had CPT score > A5. Different DAAs regimens were used. Concomitant drugs were common: 163 patients (95,8%) taking at least one drug. In 11 patients, usual therapy had to be changed to start antiviral treatment. Two serious adverse events occurred. Four patients terminated treatment prematurely. In total, 45 patients (26,5%) testified mild side effects. HCV-RNA undetectability at week 12 of treatment follow-up was achieved in 168/170 patients. DAA treatment in HCV patients of 80 years or older is efficacious and safe. Drug-drug interaction should be judiciously evaluated before starting therapy.

Cardiovascular risk factors, nonalcoholic fatty liver disease, and carotid artery intima-media thickness in an adolescent population in southern Italy.

The objective of this study was to determine, in an adolescent population, the prevalence of nonalcoholic fatty liver disease (NAFLD) and the association of NAFLD and cardiovascular risk factors with carotid artery intima-media thickness (IMT), a marker of subclinical atherosclerosis. The authors conducted a population-based study among 642 randomly selected adolescents aged 11-13 years in Reggio Calabria, southern Italy, between November 2007 and October 2008. Prevalences of overweight and obesity were 30.5% and 13.5%, respectively. The overall prevalence of NAFLD was 12.5%, increasing to 23.0% in overweight/obese adolescents. In univariate analysis, increased IMT was positively associated with the presence of NAFLD, body mass index (BMI), waist circumference, systolic blood pressure (all P's < 0.001), diastolic blood pressure (P = 0.006), gamma-glutamyl transpeptidase (P = 0.006), alanine aminotransferase (P = 0.007), and C-reactive protein (P = 0.008) and was inversely associated with high density lipoprotein cholesterol (P < 0.001). In multivariate analysis, NAFLD (P = 0.002), BMI (P = 0.004), waist circumference (P = 0.003), and systolic blood pressure (P = 0.005) retained significant associations. The authors conclude that NAFLD, BMI, waist circumference, and systolic blood pressure are independent markers of increased IMT in a random sample of adolescents.

Body mass index, cardiovascular risk factors, and carotid intima-media thickness in a pediatric population in southern Italy.

OBJECTIVES: Obesity and exposure to cardiovascular risk factors during adolescence may be associated with the development of atherosclerosis and cardiovascular diseases later in life. The objective of the study was to investigate whether any excess body weight, including moderate overweight, is associated with a more severe cardiovascular risk profile and signs of early atherosclerosis in a pediatric population. PATIENTS AND METHODS: A cross-sectional study was conducted among 646 adolescents ages 11 to 13 years from several primary schools of Reggio Calabria, Italy. Body mass index, waist circumference, blood pressure, glucose, insulin, homeostatic model assessment of insulin resistance, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and C-reactive protein (CRP) were determined. All of the subjects underwent carotid ultrasonography for the measurement of intima-media thickness. Complete clinical data were available from 575 subjects. RESULTS: Overweight was similarly frequent in boys and girls (31.2% vs 31.0%), whereas prevalence of obesity was higher in boys (18.4% vs 10.1%). Subjects with lower levels of HDL and higher levels of triglycerides, insulin, and CRP plasma were observed more frequently among overweight and obese subjects than nonoverweight. At multivariate analysis, HDL cholesterol, insulin, and CRP were associated (P < 0.05) with overweight and obesity in girls, whereas in boys, insulin and CRP were associated (P < 0.05) with overweight and obesity, and LDL cholesterol with obesity. The association between overweight or obesity and increased intima-media thickness, a sign of early atherosclerosis, was present in girls (P < 0.05) and was close to statistical significance in obese boys (P = 0.07). CONCLUSIONS: Overweight and obese adolescents have a higher prevalence of cardiovascular risk factors and show signs of early atherosclerosis. In girls, in particular, overweight is sufficient to determine a more severe cardiovascular risk profile.

Innate immunity and primary biliary cirrhosis.

There has been a rapid growth in our understanding of the molecular bases of primary biliary cirrhosis (PBC). These efforts were initiated when the immunodominant mitochondrial autoantigen was cloned and sequenced. Using the recombinant cloned antigen as a tool, research has focused on the effector mechanisms of disease and the uniqueness of the primary target tissue, the intrahepatic bile ducts. Most recently, there have been experimental data suggesting that innate immunity changes may be critical to the initiation and perpetuation of the autoimmune injury, as in the case of the enhanced response of monocytes and memory B cells to infectious stimulation and environmental mimics. These observations are important as they help fill in the many gaps which remain on the most difficult subject of autoimmunity, etiology. Indeed, based on the available data, several experimental models of PBC have been developed. These models illustrate and suggest that PBC can be initiated by several mechanisms, all of which lead to loss of tolerance to the mitochondrial antigens. However, once this adaptive response develops, it appears that much of the subsequent pathology is exacerbated by innate responses. We suggest that future therapeutic efforts in PBC will depend heavily on understanding the nature of this innate immune responses and methodology to blunt their cytotoxicity.

Laparoscopic thermoablation for hepatocellular carcinoma in patients with liver cirrhosis: an effective procedure for tricky tumors.

The optimal treatment for hepatocellular carcinoma (HCC) is surgical resection. However, only a small percentage of patients are amenable to this option. Percutaneous radiofrequency interstitial thermal ablation (TA) proved to be effective in the treatment of unresectable HCC. Recent advances in laparoscopic ultrasound have improved the accuracy in detecting small intrahepatic HCC nodules missed by pre-operative imaging techniques. Our objective was to evaluate an operative combination of laparoscopic ultrasound with laparoscopic thermoablation (LTA) in the treatment of HCC not amenable to liver resection. The aim of our review was to evaluate the advantages and limits of the laparoscopic approach according the criteria of the evidence-based medicine. LTA of HCC proved to be a safe and effective technique both in the short- and long-term follow-up period. This technique may be indicated in selected cases when the percutaneous approach to the lesion is very difficult or contraindicated.

Anti-phospholipid antibody prevalence and association with subclinical atherosclerosis and atherothrombosis in the general population.

BACKGROUND: There is no agreement on the prevalence of anti-phospholipid antibodies (aPLs) and the correlation with atherosclerosis and cardiovascular (CV) events in the general population. METHODS: We performed a cross-sectional study on 1712 randomly enrolled subjects from a Northern Italian city to investigate the presence of aPLs and the association with subclinical atherosclerosis (using the carotid artery intima media thickness measured as inter-adventitia common carotid artery diameters - ICCAD) and retrospectively collected CV factors and events (i.e. acute myocardial infarction, stroke, and peripheral obliterans arterial vasculopathy) using physician-assisted questionnaires. We tested serum IgG, IgM, and IgA anti-cardiolipin, anti-beta2glycoprotein I (aGPI), and anti-phosphatidylserine-prothrombin antibodies. RESULTS: Positive aPLs were found in 15.1% of the subjects, with no differences between sex but with higher rates in older subjects. Carotid subclinical atherosclerosis was more frequent in aPL positive subjects; more specifically, aGPI IgA were associated with higher ICCAD average (adjusted beta 0.51, 95% confidence interval (CI)0.17-0.84; p = 0.003). A positive history of CV events was also more frequent in aPL positive subjects (odds ratio (OR) 1.67, 95%CI 1.08-2.54; p = 0.012), particularly peripheral obliterans arterial vasculopathy (OR 2.02; 95%CI 1.14-3.57; p = 0.015). Among subjects with a Framingham risk score >20, and/or diabetes, and/or body mass index >35 kg/m2, aPL positivity was associated to the highest risk of CV events (OR 2.52, 95%CI 1.24-5.11; p = 0.011). CONCLUSIONS: APL prevalence in the general population is higher than previously reported. CV events and subclinical atherosclerosis are more frequent in the presence of aPL, particularly when a high CV risk coexists.

The Many Faces of Covid-19 at a Glance: A University Hospital Multidisciplinary Account From Milan, Italy.

In March 2020, northern Italy became the second country worldwide most affected by Covid-19 and the death toll overtook that in China. Hospital staff soon realized that Covid-19 was far more severe than expected from the few data available at that time. The Covid-19 pandemic forced hospitals to adjust to rapidly changing circumstances. We report our experience in a general teaching hospital in Milan, the capital of Lombardy, the most affected area in Italy. First, we briefly describe Lombardy's regional Covid-19-related health organizational changes as well as general hospital reorganization. We also provide a multidisciplinary report of the main clinical, radiological and pathological Covid-19 findings we observed in our patients.

Advanced liver disease outcomes after hepatitis C eradication by human immunodeficiency virus infection in PITER cohort.

BACKGROUND: Liver disease progression after Hepatitis C Virus (HCV) eradication following direct-acting antiviral (DAA) treatment in the real-life setting according to Human Immunodeficiency Virus (HIV) coinfection was evaluated. METHODS: Patients consecutively enrolled in PITER between April 2014 and June 2019 and with at least 12-weeks follow-up following treatment were analysed. Cox regression analysis were used to evaluate HIV coinfection and factors independently associated with liver disease outcomes following viral eradication in DAA treated patients with pre-treatment liver cirrhosis. RESULTS: 93 HIV/HCV coinfected and 1109 HCV monoinfected patients were evaluated during a median follow-up of 26.7 (range 6-44.6) and 24.6 (range 6.8-47.3) months, respectively. No difference in the cumulative HCC incidence and hepatic decompensation was observed between coinfected and monoinfected patients. Age (Hazard Ratio [HR] = 1.08; 95% CI 1.04-1.13), male sex (HR = 2.76; 95% CI 1.28-5.96), lower albumin levels (HR = 3.94; 95% CI 1.81-8.58), genotype 3 (HR = 5.05; 95% CI 1.75-14.57) and serum anti-HBc positivity (HR = 1.99, 95% CI 1.01-3.95) were independently associated with HCC incidence. Older age (HR = 1.03; 95% CI 1.00-1.07), male sex (HR = 2.13; 95% CI 1.06-4.26) and lower albumin levels (HR = 3.75; 95% CI 1.89-7.46) were independently associated with the appearance of a decompensating event after viral eradication. CONCLUSION: Different demographic, clinical and genotype distribution between HIV coinfected vs those monoinfected, was observed in a representative cohort of HCV infected patients in Italy. Once liver cirrhosis is established the disease progression is decreased, but still persists regardless of viral eradication in both coinfected and monoinfected patients. In patients with cirrhosis, HIV coinfection was not associated with a higher probability of liver complications, after viral eradication.
