RESUMO
Cirrhosis is frequently associated with sarcopenia, with reported rates of over 80% in patients with decompensated alcohol-related liver disease. Sarcopenia negatively impacts the prognosis of cirrhotic patients and affects the response to treatment of patients with hepatocellular carcinoma (HCC). For these reasons, identifying an easy-to-perform method to assess sarcopenia in is a key element in the optimization of care in this patient population. Assessment of muscle mass by computed tomography is considered the standard of care for the diagnosis of sarcopenia, but exposure to radiation and high costs limit its application in this setting, especially for repeated assessments. We believe that ultrasound, a cheap and harmless technique also used for HCC screening in cirrhotic patients, could have an expanding role in the diagnosis and follow-up of sarcopenia in these patients.

Patients with chronic liver disease face debilitating complications in their daily living and constantly report several types of unmet needs, but there is a paucity of validated questionnaires to assess these needs. In this study, we present the development of the Needs Evaluation Questionnaire for Liver Diseases (NEQ-LD) for the assessment of unmet needs in patients with chronic liver disease. Two hundred eighty-six outpatients with chronic liver diseases from a single tertiary referral center completed the NEQ-LD and related validity measures. Item response theory analyses were performed and demonstrated the strong psychometric properties of the questionnaire. Differential item functioning analyses showed that the scale functions equally across groups differing for age, sex, and presence of cirrhosis, suggesting the large applicability of the NEQ-LD for the assessment of unmet needs and between-group comparisons. Criterion validity measures provided evidence that unmet needs were positively associated with measures of depression and anxiety and negatively associated with measures of subjective well-being and physical and mental health. Unmet needs were expressed by a high percentage of patients, especially in the areas of information and dialogue with clinicians. One third of the sample reported material needs. Most of the items describing unmet needs were reported more frequently by patients with cirrhosis. Conclusion: We developed a reliable, valid, and largely employable instrument that can promote patient-centered care and facilitate support services in Hepatology.

AIM: This study investigated how material deprivation in Italy influences the stage of hepatocellular carcinoma (HCC) at diagnosis and the chance of cure. METHODS: 4114 patients from the Italian Liver Cancer database consecutively diagnosed with HCC between January 2008 and December 2018 were analysed about severe material deprivation (SMD) rate tertiles of the region of birth and region of managing hospitals, according to the European Statistics on Income and Living Conditions. The main outcomes were HCC diagnosis modalities (during or outside surveillance), treatment adoption and overall survival. RESULTS: In more deprived regions, HCC was more frequently diagnosed during surveillance, while the incidental diagnosis was prevalent in the least deprived. Tumour characteristics did not differ among regions. The proportion of patients undergoing potentially curative treatments progressively decreased as the SMD worsened. Consequently, overall survival was better in less deprived regions. Patients who moved from most deprived to less deprived regions increased their probability of receiving potentially curative treatments by 1.11 times (95% CI 1.03 to 1.19), decreasing their mortality likelihood (hazard ratio 0.78 95% CI 0.67 to 0.90). CONCLUSIONS: Socioeconomic status measured through SMD does not seem to influence HCC features at diagnosis but brings a negative effect on the chance of receiving potentially curative treatments. Patient mobility from the most deprived to the less deprived regions increased the access to curative therapies, with the ultimate result of improving survival.
RESUMO
The assessment of well-being remains an important topic for many disciplines including medical, psychological, social, educational, and economic fields. The present study assesses the reliability and validity of a five-item instrument for evaluating physical, psychological, spiritual, relational, and general well-being. This measure uniquely utilizes a segmented numeric version of the visual analog scale in which a respondent selects a whole number that best reflects the intensity of the investigated characteristic. In study one, 939 clinical (i.e., diagnosed with cancer and liver disease with cirrhosis) and non-clinical (i.e., undergraduate students and their family and acquaintances) participants between the ages of 18 to 87 years (M = 47.20 years, SD = 19.62, 54% males) were recruited. Results showed items have strong discriminant ability and the spread of threshold parameters attests to the appropriateness of the response categories. Moreover, convergent and discriminant validity were found with other self-report measures (e.g., depression, anxiety, optimism, well-being) and the measure showed responsiveness to two separate interventions for clinical populations. In study two, 287 Canadian (ages ranged from 18 to 30 years; M = 20.78, SD = 3.32; 23% males) and 342 Italian undergraduate psychology students (age ranged from 18 to 29 years, M = 21.21 years, SD = 1.73, 38% males) were recruited to complete self-report questionnaires. IRT-based differential item functioning analyses provided evidence that the item properties were similar for the Italian and English versions of the scale. Additionally, the validity results obtained in study one were replicated and similar relationships between criterion variables were found when comparing the Italian- and the English-speaking samples. Overall, the current study provides evidence that the Italian and English versions of the WB-NRSs offer added value in research focused on well-being and in assessing well-being changes prompted by intervention programs.

In chronic hepatitis B (CHB) patients, fibrosis assessment during antiviral treatment is a key step in the clinical management. Aim of this study was to evaluate the performance of elastography in assessing fibrosis stage in CHB before and after two years of nucleoside/nucleotide analogues (NUC) treatment in comparison with indirect serum markers. CHB diagnosis was made according to standard criteria. A clinical and virological evaluation was performed at baseline and again at 3, 6, 9, 12 18, and 24 months during treatment. Fibrosis was evaluated by liver biopsy, elastography and indirect serum markers. Of 75 patients, 50 had CHB, HBeAg negative and were deemed eligible for this study. Of these, 22 underwent liver biopsy. Mean histo-morphometric values of fibrotic tissue differed significantly in the stage < S3 vs. stage ≥S3: 2.01±2.62% vs. 12.85±7.31% (p=0.03), respectively. At 18 and 24 months, stiffness values were statistically reduced from those previously observed (P=0.03 and P<0.001). At 24 months the values of APRI, FIB-4 and LOK were not different from baseline values, while the value of FORNS score at 24 months was the only one statistically reduced. In two patients with fibrosis stage S3 and S6, respectively, fibrosis regressed to stage S2 and S5. In conclusion, the results of the present study show that liver histology, stiffness and FORNS score improve significantly during a long-term follow-up of HBV patients successfully treated with NUC. These results strongly suggest that the non-invasive evaluation of liver fibrosis represents a key step in the management and treatment of chronic HBV hepatitis.

BACKGROUND: The accuracy of non-invasive methods for the quantification of liver fibrosis in primary biliary cholangitis (PBC) is still debated. AIMS: To determine the histo-morphometric measurement of fibrotic tissue and to explore the possible association between indirect markers (APRI, FORNS, FIB-4, and Lok) and morphometry. METHODS: Retrospective analysis of medical data from patients with PBC, on whom needle liver biopsy was performed as part of the diagnostic assessment. One section of each biopsy stained with Sirius red was used for calculating the percentage of collagen. Quantitative measure of fibrotic tissue (fibrosis morphometry) was calculated as a percentage of collagen content by digital image analysis. Morphometry results were divided into four groups reflecting Ludwig's staging and compared with values for indirect serum markers. RESULTS: 50 PBC patients were enrolled (86% females, mean age 57 ± 12.30 years), 19 were Ludwig's stage I (38%), 14 stage II (28%), 12 stage III (24%), and five stage IV (10%). Morphometry results were significantly different among Ludwig stages (p<0.05). No significant differences were found for indirect serum markers. A significant correlation was found between morphometry results and indirect serum markers tested (p<0.05). CONCLUSION: In our cohort, the histo-morphometric values of fibrotic tissue increased progressively with Ludwig's stages of PBC, while non-invasive markers did not.

BACKGROUND: Liver stiffness has been suggested as a parameter of fibrosis progression/regression in hepatitis C virus (HCV) patients. AIM: To evaluate stiffness before and after peginterferon-ribavirin treatment. METHODS: Stiffness was prospectively measured in 74 HCV patients, 32 genotypes 1/4 (43.25%) and 42 genotypes 2/3 (56.75%), before, at end of treatment, and after 3 years of follow-up (49 patients). On the same study day, 21 patients underwent liver biopsy. RESULTS: In 55 patients with sustained virological response (74.32%), liver stiffness decreased significantly at end of therapy (6.8±4.9kPa) vs. baseline (9.5±6.9kPa, p=0.04). The decrease vs. baseline was maintained in 30 sustained virological response patients after 3 years follow-up (6.8±4.6kPa vs. 10.8±8.5kPa, p=0.0141). No difference was found at end of treatment vs. baseline (10.1±4.7kPa vs. 9.7±4.2kPa, p=0.825) and after 3 years of follow-up vs. baseline (10.2±3.4kPa vs. 9.7±4.2kPa, p=0.765) in null responders. Similar results were found in relapsers at end of treatment vs. baseline (13.7±7.7kPa vs. 15.2±8.2kPa, p=0.74), and after 3 years of follow-up vs. baseline (16.9±10.0kPa vs. 15.2±8.2kPa, p=0.734). Pre-treatment stiffness >12kPa was significantly associated with no SVR (p<0.025), RR=2.44 (95%C.I. 1.17-5.07). CONCLUSION: Liver stiffness may be useful to assess long-term antiviral treatment response.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in Western countries, and its prevalence is increasing worldwide. It currently affects approximately 30% of adults and 10% of children and adolescents. The resulting increase in the number of patients with NAFLD is expected to translate into increased numbers of patients with liver cirrhosis, and hepatocellular carcinoma. In this context, it is particularly important to identify patients at risk for progressive chronic liver disease. Currently, liver biopsy is the gold standard to diagnose non-alcoholic steatohepatitis (NASH) and to establish the presence and stage of fibrosis. Due to the remarkable increase in the prevalence of NAFLD and the concomitant efforts in developing novel therapies for patients with NASH, non-invasive, simple, reproducible, and reliable non-invasive methodologies are needed. This paper provides a concise overview of the role of non-invasive diagnostic tools for the determination of presence and extent of fibrosis in NAFLD patients, with particular emphasis on the methods currently available in clinical practice.

Although histopathological analysis of liver tissue is still the reference standard for the evaluation of disease progression in patients with chronic liver disease, a distinct change in clinical practice is occurring. The tendency to substitute histopathological analysis of liver biopsies with complex, surrogate 'noninvasive' measures of disease progression has grown to such a level that clarification and guidance on their use is needed. This Review provides an overview of the proposed noninvasive diagnostic methodologies and their possible integration with the standard invasive procedures used for the evaluation of disease progression (i.e. liver biopsy and the measurement of portal pressure). A concise analysis of what has been proposed for the differentiation of simple fatty liver from nonalcoholic steatohepatitis and its possible fibrogenic evolution is also included. In particular, the Review focuses on the methods easily available as part of daily clinical practice in hepatology--biochemical markers and transient elastography (i.e. liver stiffness measurement).
