Association between esophageal motor disorders and pulmonary involvement in patients affected by systemic sclerosis: a retrospective study.

Systemic sclerosis (SSc) is a rare autoimmune disease of the connective tissue that can affect multiple organs. The esophagus is the most affected gastrointestinal tract, while interstitial lung disease (ILD) is a main feature associated with SSc. The aim of the present study was to evaluate the association and prognostic implication between motor esophageal disorders and pulmonary involvement in SSc patients. We retrospectively assessed patients with SSc who underwent both the HRM with the new Chicago Classification 4.0 and pulmonary evaluation comprehensive of function tests and high-resolution computer tomography (HrCT) with the use of Warrick score. A total score ≥ 7 was considered predictive of ILD, while a score ≥ 10 in a HrCT acquired prospectively from baseline evaluation was considered to establish significant interstitial involvement. Forty-two patients were included. We found a score ≥ 7 in 11 patients with aperistalsis, in 6 subjects with IEM and in 6 patients with a normal manometry. Otherwise, a score < 7 was observed in 3 patients with aperistalsis, and in 2 and 14 patients with IEM and with a normal contractility, respectively. Higher scores were observed in subjects with absent contractility or ineffective esophageal motility than subjects with normal motility, indeed DCI and HrCT score were inversely correlated in linear and logarithmic regression analysis. Prospectively, lower baseline LESP and greater HrCT scores at follow-up evaluation were significantly correlated. This study shows an association between motor esophageal disorder and pulmonary involvement in SSc patients: more severe is the esophageal involvement, more critical is the pulmonary disease.

Predictors of serious adverse events and non-response in cirrhotic patients with primary biliary cholangitis treated with obeticholic acid.

BACKGROUND & AIMS: Obeticholic acid (OCA) has recently been restricted in patients with primary biliary cholangitis (PBC) with "advanced cirrhosis" because of its narrow therapeutic index. We aimed to better define the predicting factors of hepatic serious adverse events (SAEs) and non-response in cirrhotic patients undergoing OCA therapy. METHODS: Safety and efficacy of treatment were evaluated in a cohort of consecutive PBC cirrhotic patients started with OCA. OCA response was evaluated according to the Poise criteria. Risk factors for hepatic SAEs and non-response were reported as risk ratios (RR) with 95% confidence intervals (CIs). RESULTS: One hundred PBC cirrhotics were included, 97 Child-Pugh class A and 3 class B. Thirty-one had oesophageal varices and 5 had a history of ascites. Thirty-three per cent and 32% of patients achieved a biochemical response at 6 and 12 months respectively. Male sex (adjusted-RR 1.75, 95%CI 1.42-2.12), INR (1.37, 1.00-1.87), Child-Pugh score (1.79, 1.28-2.50), MELD (1.17, 1.04-1.30) and bilirubin (1.83, 1.11-3.01) were independently associated with non-response to OCA. Twenty-two patients discontinued OCA within 12 months: 10 for pruritus, 9 for hepatic SAEs (5 for jaundice and/or ascitic decompensation; 4 for upper digestive bleeding). INR (adjusted-RR 1.91, 95%CI 1.10-3.36), lower albumin levels (0.18, 0.06-0.51), Child-Pugh score (2.43, 1.50-4.04), history of ascites (3.5, 1.85-6.5) and bilirubin (1.30, 1.05-1.56), were associated with hepatic SAEs. A total bilirubin≥1.4 mg/dl at baseline was the most accurate biochemical predictor of hepatic SAEs under OCA. CONCLUSIONS: An accurate baseline assessment is crucial to select cirrhotic patients who can benefit from OCA. Although OCA is effective in one third of cirrhotics, bilirubin level ≥1.4 mg/dl should discourage from its use.

Achalasia and Obstructive Motor Disorders Are Not Uncommon in Patients With Eosinophilic Esophagitis.

BACKGROUND: An association has been reported between achalasia and eosinophilic esophagitis (EoE). We performed a retrospective study of high-resolution manometry (HRM) patterns in a large cohort of patients with EoE. MATERIAL AND METHODS: We collected data from consecutive patients with a new diagnosis of EoE from 2012 through 2019 undergoing HRM during the initial assessment at different centers in Italy. Demographic, clinical, endoscopic and histological characteristics were recorded at baseline and during management. Diagnoses of EoE and esophageal motility disorders were made according to established criteria. Treatments offered included proton pump inhibitors and topical steroids for EoE, and pneumatic dilation and myotomy for achalasia. Response to therapy was defined as less than 15 eosinophils per high power field in esophageal biopsies. RESULTS: Of 109 consecutive patients (mean age 37 years, 82 male), 68 (62%) had normal findings from HRM. Among 41 patients with motor disorders, 24 (59%) had minor motor disorders and 17 (41%) presented with major motor disorders, including 8 with achalasia (1 with type 1, 4 with type 2, and 3 with type 3). Achalasia and nonachalasia obstructive motor disorders had 14.7% prevalence among patients with EoE. Achalasia was more frequent in women, with longer diagnostic delay and abnormal esophagogram (P < .05) compared with EoE without achalasia or obstructive motor disorders. Clinical features and endoscopic findings did not differ significantly between patients with EoE with vs without achalasia and obstructive motor disorders. A higher proportion of patients without achalasia and obstructive motor disorders responded to topical steroids than patients with these features (P < .005). Invasive achalasia management was required for symptom relief in 50% of patients with achalasia and obstructive motor disorders. CONCLUSION: Achalasia and obstructive motor disorders are found in almost 15% of patients with EoE, and esophageal eosinophilia might cause these disorders. Patients with EoE who do not respond to standard treatments might require targeted muscle disruption.

Procedure-related bleeding risk in patients with cirrhosis and severe thrombocytopenia.

BACKGROUND: Gaps of knowledge still exist about the potential association between severe thrombocytopenia and increased risk of procedure-associated bleeding in patients with liver disease. METHODS: In this narrative review, we aimed at examining the association between procedure-related bleeding risk and platelet count in patients with cirrhosis and severe thrombocytopenia in various settings. We updated to 2020 a previously conducted literature search using MEDLINE/PubMed and EMBASE. The search string included clinical studies, adult patients with chronic liver disease and thrombocytopenia undergoing invasive procedures, any interventions and comparators, and haemorrhagic events of any severity as outcome. RESULTS: The literature search identified 1276 unique publications, and 15 studies met the inclusion criteria and were analysed together with those identified by the previous search. Most of the new studies included in our analysis did not assess the association between post-procedural bleeding risk and platelet count alone in patients with chronic liver disease. Furthermore, some results could have been biased by prophylactic platelet transfusions. A few studies found that severe thrombocytopenia may be predictive of bleeding following percutaneous liver biopsy, dental extractions, percutaneous ablation of liver tumours and endoscopic polypectomy. CONCLUSIONS: Currently available literature cannot support definitive conclusions about the appropriate target platelet counts to improve the risk of bleeding in cirrhotic patients who underwent invasive procedures; moreover, it showed enormous variability in the use of prophylactic platelet transfusions.

Undefined/non-malignant hepatic nodules are associated with early occurrence of HCC in DAA-treated patients with HCV-related cirrhosis.

BACKGROUND & AIM: An unexpected early increase in incidence, recurrence and clinical aggressiveness of hepatocellular carcinoma (HCC) has been reported (and refuted) in patients with HCV-related cirrhosis following direct-acting antiviral (DAA) treatment. To address this controversy, we performed a prospective multicenter study on consecutively enrolled cirrhotic patients, with or without a history of HCC, undergoing DAA therapy. PATIENTS AND METHODS: A total of 1,161 HCC-free cirrhotics (group 1) and 124 cirrhotics who had received a curative treatment for an HCC (group 2) were enrolled. Clinical features, including presence of undefined/non-malignant liver nodules (UNMNs), were analyzed with respect to HCC incidence and recurrence. RESULTS: During a median study time of 17 months in group 1 and 16 months in group 2, de novo HCC developed in 48 patients (yearly incidence 3.1/100 patient-years, 75% BCLC 0-A) and recurred in 40 (mean yearly incidence 29.9/100 patient-years, 83% BCLC 0-A). A peak of HCC instant incidence was observed at 4.2 months in group 1 patients with UNMNs, and at 7.7 months in group 2. By multivariable Cox regression models, UNMNs (hazard ratio [HR] 3.11; 95% CI 1.47-6.57: p = 0.003), ascites detected any time before enrolment (HR 3.04; 95% CI 1.23-7.51; p = 0.02), and alpha-fetoprotein log-value (HR 1.90; 95% CI 1.05-3.44; p = 0.03) were the variables independently associated with the incidence of de novo HCC, while history of alcohol abuse (HR 2.10; 95% CI 1.08-4.09; p = 0.03) and history of recurrence of HCC (HR 2.87; 95% CI 1.35-6.09; p = 0.006) were associated with HCC recurrence. CONCLUSION: An early high incidence of both de novo HCC, in patients with UNMNs, and recurrent HCC was observed in DAA-treated patients; this was not accompanied by increased tumor aggressiveness. LAY SUMMARY: This prospective study focuses on the risk of developing de novo or recurrent hepatocellular carcinoma (HCC) after direct-acting antiviral (DAA) treatment in patients with hepatitis C-related cirrhosis. We found that DAA treatment was associated with an early high HCC incidence in patients with undefined or non-malignant nodules, as well as in those with a history of complete response to HCC treatment. Whether this is related to the presence of clinically undetectable nests of cancer cells or to precancerous lesions that may progress to overt HCC upon DAA treatment remains unanswered. No evidence of increased clinical aggressiveness was reported in de novo or recurrent HCC.

Patients with advanced hepatocellular carcinoma need a personalized management: A lesson from clinical practice.

The Barcelona Clinic Liver Cancer (BCLC) advanced stage (BCLC C) of hepatocellular carcinoma (HCC) includes a heterogeneous population, where sorafenib alone is the recommended treatment. In this study, our aim was to assess treatment and overall survival (OS) of BCLC C patients subclassified according to clinical features (performance status [PS], macrovascular invasion [MVI], extrahepatic spread [EHS] or MVI + EHS) determining their allocation to this stage. From the Italian Liver Cancer database, we analyzed 835 consecutive BCLC C patients diagnosed between 2008 and 2014. Patients were subclassified as: PS1 alone (n = 385; 46.1%), PS2 alone (n = 146; 17.5%), MVI (n = 224; 26.8%), EHS (n = 51; 6.1%), and MVI + EHS (n = 29; 3.5%). MVI, EHS, and MVI + EHS patients had larger and multifocal/massive HCCs and higher alpha-fetoprotein (AFP) levels than PS1 and PS2 patients. Median OS significantly declined from PS1 (38.6 months) to PS2 (22.3 months), EHS (11.2 months), MVI (8.2 months), and MVI + EHS (3.1 months; P < 0.001). Among MVI patients, OS was longer in those with peripheral than with central (portal trunk) MVI (11.2 vs. 7.1 months; P = 0.005). The most frequent treatments were: curative approaches in PS1 (39.7%), supportive therapy in PS2 (41.8%), sorafenib in MVI (39.3%) and EHS (37.3%), and best supportive care in MVI + EHS patients (51.7%). Independent prognostic factors were: Model for End-stage Liver Disease score, Child-Pugh class, ascites, platelet count, albumin, tumor size, MVI, EHS, AFP levels, and treatment type. CONCLUSION: BCLC C stage does not identify patients homogeneous enough to be allocated to a single stage. PS1 alone is not sufficient to include a patient into this stage. The remaining patients should be subclassified according to PS and tumor features, and new patient-tailored therapeutic indications are needed. (Hepatology 2018;67:1784-1796).

Factors that affect efficacy of ultrasound surveillance for early stage hepatocellular carcinoma in patients with cirrhosis.

BACKGROUND & AIMS: Ultrasound surveillance does not detect early stage hepatocellular carcinomas (HCCs) in some patients with cirrhosis, although the reasons for this have not been well studied. We assessed the rate at which ultrasound fails to detect early stage HCCs and factors that affect its performance. METHODS: We collected information on 1170 consecutive patients included in the Italian Liver Cancer (ITA.LI.CA) database who had Child-Pugh A or B cirrhosis and were diagnosed with HCC during semiannual or annual ultrasound surveillance, from January 1987 through December 2008. Etiologies included hepatitis C virus infection (59.3%), alcohol abuse (11.3%), hepatitis B virus infection (9%), a combination of factors (15.6%), and other factors (4.7%). Surveillance was considered to be a failure when patients were diagnosed with HCC at a stage beyond the Milan criteria (1 nodule ≤5 cm or ≤3 nodules each ≤3 cm). RESULTS: HCC was found beyond Milan criteria in 34.3% of surveilled patients (32.2% during semi-annual surveillance and 41.3% during annual surveillance; P < .01). Nearly half of surveillance failures were associated with at least one indicator of aggressive HCC (levels of AFP >1000 ng/mL, infiltrating tumors, or vascular invasion and metastases). Semiannual surveillance, female sex, Child-Pugh class A, and α-fetoprotein levels of 200 ng/mL or less were associated independently with successful ultrasound screening for HCC. CONCLUSIONS: Based on our analysis of surveillance for HCC in patients with cirrhosis, the efficacy of ultrasound-based screening is acceptable. Ultrasound was least effective in identifying aggressive HCC, and at surveillance intervals of more than 6 months.

Food Intolerances, Food Allergies and IBS: Lights and Shadows.

This narrative review delves into the intricate relationship between irritable bowel syndrome (IBS) and food intolerances. IBS, a chronic functional gastrointestinal disorder, is characterized by symptoms like abdominal pain and altered bowel habits. The prevalence of IBS has increased globally, especially among young adults. Food and dietary habits play a crucial role in IBS management. About 85-90% of IBS patients report symptom exacerbation linked to specific food consumption, highlighting the strong connection between food intolerances and IBS. Food intolerances often exhibit a dose-dependent pattern, posing a challenge in identifying trigger foods. This issue is further complicated by the complex nature of gastrointestinal physiology and varying food compositions. This review discusses various dietary patterns and their impact on IBS, including the low-FODMAP diet, gluten-free diet, and Mediterranean diet. It highlights the importance of a personalized approach in dietary management, considering individual symptom variability and dietary history. In conclusion, this review emphasizes the need for accurate diagnosis and holistic management of IBS, considering the complex interplay between dietary factors and gastrointestinal pathophysiology. It underlines the importance of patient education and adherence to treatment plans, acknowledging the challenges posed by the variability in dietary triggers and the psychological impact of dietary restrictions.

Multidisciplinary treatment of hepatocellular carcinoma in 2023: Italian practice Treatment Guidelines of the Italian Association for the Study of the Liver (AISF), Italian Association of Medical Oncology (AIOM), Italian Association of Hepato-Bilio-Pancreatic Surgery (AICEP), Italian Association of Hospital Gastroenterologists (AIGO), Italian Association of Radiology and Clinical Oncology (AIRO), Italian Society of Pathological Anatomy and Diagnostic Cytology (SIAPeC-IAP), Italian Society of Surgery (SIC), Italian Society of Gastroenterology (SIGE), Italian Society of Medical and Interventional Radiology (SIRM), Italian Organ Transplant Society (SITO), and Association of Patients with Hepatitis and Liver Disease (EpaC) - Part II - Non-surgical treatments.

Worldwide, hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death. The remarkable improvements in treating HCC achieved in the last years have increased the complexity of its management. Following the need to have updated guidelines on the multidisciplinary treatment management of HCC, the Italian Scientific Societies involved in the management of this cancer have promoted the drafting of a new dedicated document. This document was drawn up according to the GRADE methodology needed to produce guidelines based on evidence. Here is presented the second part of guidelines, focused on the multidisciplinary tumor board of experts and non-surgical treatments of HCC.

Reduction of Fecal Calprotectin Levels Induced by a Short Course of Escherichia Coli Nissle is Associated with a Lower Likelihood of Disease Flares in Patients with Ulcerative Colitis in Clinical Remission.

BACKGROUND AND AIMS: Fecal calprotectin (FC) is a biomarker of gut inflammation, and Escherichia coli Nissle 1917 (EcN) is a probiotic strain able to reduce gut inflammation and maintain disease remission in patients with inflammatory bowel disease (IBD). The aim is to assess the effects of EcN administration in patients with IBD in clinical remission and altered FC values. METHODS: We prospectively included 82 patients with ulcerative colitis (UC) (n=49) and Crohn's disease (CD) (n=33) in clinical remission and with FC values above 250 mcg/g (T0) who were treated with EcN alone for 2 months. FC values were assessed at the end of EcN treatment (T1) and clinical disease activity at 3 months (T2). RESULTS: At T1 median FC values were significantly lower compared to T0 both in patients with CD (312 mcg/g vs 626 mcg/g, p<0.0001) and UC (100 mcg/g vs 584 mcg/g; p<0.0001). Patients with UC who experienced disease relapse at T2 had lesser reduction in median FC values at T1 (-229 mcg/g, vs -397 mcg/g, p=0.049), while in patients with CD we observed no statistically significant difference (-358 mcg/g, vs -427; p=0.568). In patients with UC, a reduction of at least 532 mcg/g in FC had an accuracy of 69.7% and a positive predictive value of 65.7% in predicting maintenance of remission. CONCLUSIONS: A short course of EcN was associated with a reduction of FC values in patients with IBD in clinical remission and baseline altered FC values, and in patients with UC this decrease was associated with maintenance of clinical remission.

Albumin-bilirubin score in non-malignant liver diseases should be properly validated.

The albumin-bilirubin (ALBI) score to assess the risk of decompensation in patients with initially compensated cirrhosis may improve their prognostic evaluation. This letter critically evaluates the research, which utilizes the ALBI score to forecast decompensation in cirrhosis patients over a three-year period. This score was initially developed to assess liver function in hepatocellular carcinoma, its prognostic utility for non-malignant liver diseases has now been explored, recognizing decompensation as a pivotal event that significantly affects patient's survival. Some concerns regarding the methodology of this research may be raised, particularly the exclusive use of radiological diagnosis, potentially including patients without definite cirrhosis and thus skewing the decompensation risk assessment. The reported predominance of variceal bleeding as a decompensating event conflicts with established literature, that often reports ascites as the initial decompensation manifestation. The letter highlights the absence of details on esophageal varices and their management, which could introduce bias in evaluating the ALBI score's predictive power. Furthermore, the letter points out the small sample size of patients with high-risk ALBI grades, potentially compromising the score's validity in this context. We suggest prospective future research to investigate the dynamic changes in the ALBI score over time to reinforce the validity of the ALBI score as a predictor of decompensation in non-malignant liver disease.

Excellent outcome in patients with primary biliary cholangitis in Northwest Italy followed up for up to 30†years.

OBJECTIVE: Primary biliary cholangitis (PBC) is a rare chronic autoimmune cholangiopathy, characterized by a variable course and response to treatment. We aimed to describe long-term outcomes of PBC patients referred to three academic centres in Northwest Italy. METHODS: This is an ambispective cohort study of PBC patients (retrospective component: diagnosis before 1 January 2019; prospective component: thereafter), including 302 patients: 101 (33%) followed up in Novara, 86 (28%) in Turin, 115 (38%) in Genoa. Clinical features at diagnosis, biochemical response to therapy and survival were analyzed. RESULTS: Among the 302 patients (88% women, median age 55 years, median follow-up 75 months), alkaline phosphatase (ALP) levels significantly decreased during treatment with ursodeoxycholic acid (UDCA, P < 0.0001) and obeticholic acid (P < 0.0001). At multivariate analysis, ALP at diagnosis was predictive of 1-year biochemical response to UDCA [odds ratio 3.57, 95% confidence interval (CI) 1.4-9, P < 0.001]. Estimated median survival free of liver transplantation and hepatic complications was 30 years (95% CI 19-41). Bilirubin level at diagnosis was the only independent risk factor for the combined outcome of death, transplantation or hepatic decompensation (hazard ratio, 1.65, 95% CI 1.66-2.56, P = 0.02). Patients presenting with total bilirubin at diagnosis ≥0.6 times the upper normal limit (ULN) had a significantly lower 10-year survival compared to those with bilirubin <0.6 times ULN (63% vs. 97%, P < 0.0001). CONCLUSION: In PBC, both short-term response to UDCA and long-term survival can be predicted by simple conventional biomarkers of disease severity, obtained at diagnosis.

The Italian data on SARS-CoV-2 infection in transplanted patients support an organ specific immune response in liver recipients.

Introduction: The study of immune response to SARSCoV-2 infection in different solid organ transplant settings represents an opportunity for clarifying the interplay between SARS-CoV-2 and the immune system. In our nationwide registry study from Italy, we specifically evaluated, during the first wave pandemic, i.e., in non-vaccinated patients, COVID-19 prevalence of infection, mortality, and lethality in liver transplant recipients (LTRs), using non-liver solid transplant recipients (NL-SOTRs) and the Italian general population (GP) as comparators. Methods: Case collection started from February 21 to June 22, 2020, using the data from the National Institute of Health and National Transplant Center, whereas the data analysis was performed on September 30, 2020.To compare the sex- and age-adjusted distribution of infection, mortality, and lethality in LTRs, NL-SOTRs, and Italian GP we applied an indirect standardization method to determine the standardized rate. Results: Among the 43,983 Italian SOTRs with a functioning graft, LTRs accounted for 14,168 patients, of whom 89 were SARS-CoV-2 infected. In the 29,815 NL-SOTRs, 361 cases of SARS-CoV-2 infection were observed. The geographical distribution of the disease was highly variable across the different Italian regions. The standardized rate of infection, mortality, and lethality rates in LTRs resulted lower compared to NL-SOTRs [1.02 (95%CI 0.81-1.23) vs. 2.01 (95%CI 1.8-2.2); 1.0 (95%CI 0.5-1.5) vs. 4.5 (95%CI 3.6-5.3); 1.6 (95%CI 0.7-2.4) vs. 2.8 (95%CI 2.2-3.3), respectively] and comparable to the Italian GP. Discussion: According to the most recent studies on SOTRs and SARS-CoV-2 infection, our data strongly suggest that, in contrast to what was observed in NL-SOTRs receiving a similar immunosuppressive therapy, LTRs have the same risk of SARS-CoV-2 infection, mortality, and lethality observed in the general population. These results suggest an immune response to SARS-CoV-2 infection in LTRS that is different from NL-SOTRs, probably related to the ability of the grafted liver to induce immunotolerance.

Cost-effectiveness of semi-annual surveillance for hepatocellular carcinoma in cirrhotic patients of the Italian Liver Cancer population.

BACKGROUND & AIMS: It was recently shown that semi-annual surveillance for hepatocellular carcinoma (HCC) in cirrhotic patients provides a prognostic advantage over the annual program; however, its cost-effectiveness (CE) in the general cirrhotic population still needs to be defined. METHODS: A Markov model was built to compare CE of these two strategies, considering literature results and treatment modalities of 918 cirrhotic patients from the Italian Liver Cancer (ITA.LI.CA) database. RESULTS: Results from the Markov model suggest that, compared to annual surveillance, semi-annual surveillance leads to a gain in quality-adjusted life expectancy, in an unselected cirrhotic population, of 1.35 quality-adjusted life-months (QALMs) over 10 years since surveillance start in compensated patients, and of 0.73 QALMs in decompensated patients. Semi-annual surveillance was more cost-effective in compensated than in decompensated cirrhosis, with an incremental CE ratio (ICER) of 1997 and 3814€/QALM, respectively. In compensated cirrhosis, semi-annual surveillance was more cost-effective than the annual program when the annual HCC incidence was ≥3.2% and the relative survival gain after cancer diagnosis was ≥20% with respect to the annual program. In decompensated cirrhosis, semi-annual surveillance was cost-effective in patients amenable to liver transplantation. In both groups, CE of semi-annual surveillance improved with the increase of annual incidence and the survival benefit obtainable with HCC treatment. CONCLUSIONS: Both surveillance strategies for HCC in cirrhotic patients can be recommended, according to the individual risk profile for HCC occurrence and the expected survival gain obtainable after tumor diagnosis and therapy.

The changing scenario of hepatocellular carcinoma over the last two decades in Italy.

BACKGROUND & AIMS: This study investigates whether the aetiologic changes in liver disease and the improved management of hepatocellular carcinoma (HCC) have modified the clinical scenario of this tumour over the last 20 years in Italy. METHODS: Retrospective study based on the analysis of the ITA.LI.CA (Italian Liver Cancer) database including 3027 HCC patients managed in 11 centres. Patients were divided into 3 groups according to the period of HCC diagnosis: 1987-1996 (year of the "Milano criteria" publication), 1997-2001 (year of release of the EASL guidelines for HCC), and 2002-2008. RESULTS: The significant changes were: (1) progressive patient ageing; (2) increasing prevalence of HCV infection until 2001, with a subsequent decrease, when the alcoholic aetiology increased; (3) liver function improvement, until 2001; (4) increasing "incidental" at the expense of "symptomatic" diagnoses, until 2001; (5) unchanged prevalence of tumours diagnosed during surveillance (around 50%), with an increasing use of the 6-month schedule; (6) favourable HCC "stage migration", until 2001; (7) increasing use of percutaneous ablation; (8) improving survival, until 2001. CONCLUSIONS: Over the last 20 years, several aetiologic and clinical features regarding HCC have changed. The survival improvement observed until 2001 was due to an increasing number of tumours diagnosed in early stages and in a background of compensated cirrhosis, and a growing and better use of locoregional treatments. However, the prevalence of early cancers and survival did not increase further in the last years, a result inciting national policies aimed at implementing surveillance programmes for at risk patients.

Barcelona Clinic Liver Cancer staging and transplant survival benefit for patients with hepatocellular carcinoma: a multicentre, cohort study.

BACKGROUND: Allocation of deceased-donor livers to patients with chronic liver failure is improved by prioritising patients by 5-year liver transplantation survival benefit. The Barcelona Clinic Liver Cancer (BCLC) staging has been proposed as the standard means to assess for prognosis of patients with hepatocellular carcinoma. We aimed to create a prediction model linking the BCLC stage of patients with hepatocellular carcinoma to their 5-year liver transplant benefit. METHODS: A large cohort of consecutive patients with hepatocellular carcinoma (n=1328) from the ITA.LI.CA database (n=2951) were judged as potentially eligible for liver transplantation according to the following criteria: absence of macroscopic vascular invasion or metastases, age 70 years or younger, and absence of relevant extra-hepatic comorbidities. To assess the correlation between BCLC staging and non-liver transplantation survival, we did Cox univariate and multivariate analyses including the following covariates: BCLC stage, year of diagnosis, age, sex, cause of cirrhosis, model for end-stage liver disease score, α-fetoprotein concentrations, and treatment. Liver-transplantation survival benefit for patients was calculated, using Monte Carlo simulation analysis, as the patient's 5-year life expectancy with liver transplantation (estimated by the Metroticket model) minus the 5-year life expectancy without liver transplantation according to BCLC stage. FINDINGS: 83 (6%) of 1328 patients had BCLC 0 stage disease, 614 (46%) had BCLC A, 500 (38%) had BCLC B-C, and 131 (10%) had BCLC D. In the Cox non-liver transplantation survival multivariate model, hazard ratios associated with increasing BCLC stages were 1.530 (95% CI 1.107-2.116) for BCLC A versus BCLC 0, 1.572 (1.350-1.830) for BCLC B-C versus BCLC A, and 1.470 (1.164-1.856) for BCLC D versus BCLC B-C. Results of the Monte Carlo simulation analysis confirmed the significant effect of BCLC classification on transplant benefit; in the adjusted model, a median 5-year transplant benefit of 11.19 months (IQR 10.73-11.67) for BCLC 0, 13.49 months (11.51-15.57) for BCLC A, 17.36 months (15.06-19.28) for BCLC B-C, and 28.46 months (26.38-30.34) for BCLC D. INTERPRETATION: Liver transplantation could result in survival benefit for patients with hepatocellular carcinoma and advanced liver cirrhosis (BCLC stage D) and in those with intermediate tumours (BCLC stages B-C), regardless of the nodule number-size criteria (ie, Milan criteria), provided that macroscopic vascular invasion and extra-hepatic disease are absent. FUNDING: None.

Primary biliary cholangitis: perception and expectation of illness.

An important tool to explore personal experience of symptoms, treatment and clinical outcome is stratification of illness perception in patients affected by PBC. AIM: To assess the perception of illness in a cohort of Italian patients with PBC. METHODS: Between June and December 2019, a specific questionnaire was administered to a pool of 210 patients from 7 tertiary Italian centers, in order to identify and assess the patient's past history, symptoms and their impact on the quality of life, follow-up, treatment and perceived satisfaction of patients toward the provided care. RESULTS: Fatigue, pruritus, and abdominal discomfort and sicca syndrome were present in 50.4%, 45%, 30.4% and 28.5% of patients, fatigue having the most impacting the daily-life. After a consultation with a specialist, the diagnosis of PBC was met within 18 months for 143 patients. Patients were mostly concerned about possible health problems that occur and in 25% of cases, symptoms had a negative impact on their life. Eighty percent of patients said they were satisfied with efficacy and tolerability of treatment, while 26% requested an improvement in the relationship with the specialist. CONCLUSIONS: The results highlight the importance of both promoting timely referral to the specialist and facilitating communication between healthcare professionals and patients.

Therapeutic drug monitoring in Crohn's disease patients treated with anti-TNF: a comparison of two techniques.

BACKGROUND: Therapeutic drug monitoring is a useful clinical decision aid in managing patients with inflammatory bowel disease treated with anti-tumor necrosis factor (anti-TNF). Various techniques are available to evaluate drug trough levels, and among these a point-of-care (POC) method has been proposed to overcome the limitations inherent to other methodologies. In this study we aimed to evaluate the capability of POC to discriminate between relapse and remission disease phases, and to assess the concordance of the POC and homogeneous mobility shift assay (HMSA) results. METHODS: Drug trough level of 46 Crohn's disease patients treated with either adalimumab or infliximab were evaluated with both a POC technique and an HMSA at various time points (week-16 and -48) during anti-TNF treatment. RESULTS: Median adalimumab trough level of patients in remission were significantly higher as compared to relapsing patients using both HMSA (week 16, P = 0.0001; week48, P = 0.001) and POC (week 16, P = 0.0003; week 48, P = 0.0012), and similar results were observed with infliximab trough level at week 16 (HMSA, P = 0.019; POC, P = 0.0072). Overall, we observed a good correlation between the techniques for both infliximab (r = 0.76; P < 0.0001) and adalimumab (r = 0.75; P < 0.0001), with no difference in discriminatory accuracy between assays (infliximab: HMSA versus POC c-index, 0.921 versus 0.895, P =0.149; adalimumab: HMSA versus POC c-index, 0.817 versus 0.850, P = 0.197). CONCLUSION: Both POC and HMSA assays are able to reliably differentiate relapse and remission phases in Crohn's disease patients treated with anti-TNF. These techniques showed good concordance and we feel that their preferential use should be based on local accessibility, physicians' experience and preference, and the need for timeliness availability of results.
