Background Maturity Onset Diabetes of the Young (MODY) is a monogenic, autosomal, dominant disease that results in beta-cells dysfunction with consequent hyperglycaemia. It represents a rare form of diabetes (1–2% of all the cases). Sulphonylureas (SUs) represent the first-line treatment for this form of diabetes mellitus. NEUROD1 is expressed by the nervous and the pancreatic tissues, and it is necessary for the proper development of beta cells. A neurogenic differentiation factor 1 (NEUROD1) gene mutation causes beta-cells dysfunction, inadequate insulin secretion, and hyperglycaemia (MODY 6). Case presentation We have documented a new missense mutation (p.Met114Leu c.340A > C) of the NEUROD1 gene, pathogenetic for diabetes mellitus, in a 48 years-old man affected by diabetes since the age of 25 and treated with insulin basal-bolus therapy. Unfortunately, an attempt to replace rapid insulin with dapagliflozin has failed. However, after the genetic diagnosis of MODY6 and treatment with SUs, he was otherwise able to suspend rapid insulin and close glucose monitoring. Interestingly, our patient had an early onset dilated cardiomyopathy, though no data about cardiac diseases in patients with MODY 6 are available. Conclusions Diagnostic criteria for MODY can overlap with other kinds of diabetes and most cases of genetic diabetes are still misdiagnosed as diabetes type 1 or 2. We encourage to suspect this disease in patients with a strong family history of diabetes, normal BMI, early-onset, and no autoimmunity. The appropriate therapy simplifies disease management and improves the quality of the patient’s life.

Background & Aims There is intense research for drugs able to reduce disease progression in nonalcoholic fatty liver disease. We aimed to test the impact of novel antidiabetic drugs (dipeptidyl‐peptidase‐4 inhibitors – DPP‐4Is, glucagon‐like peptide‐1 receptor agonists – GLP‐1RAs, sodium‐glucose cotransporter‐2 inhibitors – SGLT‐2Is) on non‐invasive biomarkers of steatosis (fatty liver index, FLI) and fibrosis (Fibrosis‐4 score, FIB‐4) in patients with type 2 diabetes (T2D). Methods Clinical, anthropometric and biochemical parameters were retrospectively analysed in 637 consecutive T2D patients switched from metformin w/wo sulfonylureas and/or pioglitazone to DPP‐4Is, GLP‐1RAs and SGLT‐2Is in a tertiary care setting. 165 patients maintained on original treatments served as controls. The effects on FLI and FIB‐4 at 6‐ and 12‐month follow‐up were analysed by logistic regression after adjustment for baseline differences, computed by propensity scores, and additional adjustment for changes in glycosylated hemoglobin (HbA1c) and body mass index. Results Body mass index, HbA1c and aminotrasferases significantly decreased following switching to GLP‐1RAs and SGLT2‐Is, compared with both controls and DPP‐4Is, whereas only HbA1c was reduced on DPP‐4Is. FLI and FIB‐4 were reduced on GLP‐1RA and SGLT‐2I; logistic regression analysis confirmed a significant improvement of both biomarkers after adjustment for propensity score. The shift of FIB‐4 values towards the category ruling out advanced fibrosis was maintained after additional adjustment for confounders. These effects were confirmed in a sensitivity analysis on effect size. Conclusions Glucagon‐like peptide‐1 receptor agonists and SGLT‐2Is improve biomarkers of steatosis and fibrosis, in keeping with beneficial effects on liver disease progression, and should be considered the treatment of choice in T2D.

No drug has so far been approved for the treatment of nonalcoholic fatty liver disease (NAFLD), a condition affecting approximately 25% of the worldwide population [1]. Also, trials specifically in...

Unhealthy behaviours, including diet and physical activity, coupled with genetic predisposition, drive type 2 diabetes (T2D) occurrence and severity; the present review aims to summarise the most recent nutritional approaches in T2D, outlining unmet needs. Guidelines consistently suggest reducing energy intake to counteract the obesity epidemic, frequently resulting in sarcopenic obesity, a condition associated with poorer metabolic control and cardiovascular disease. Various dietary approaches have been proposed with largely similar results, with a preference for the Mediterranean diet and the best practice being the diet that patients feel confident of maintaining in the long term based on individual preferences. Patient adherence is indeed the pivotal factor for weight loss and long-term maintenance, requiring intensive lifestyle intervention. The consumption of nutritional supplements continues to increase even if international societies do not support their systematic use. Inositols and vitamin D supplementation, as well as micronutrients (zinc, chromium, magnesium) and pre/probiotics, result in modest improvement in insulin sensitivity, but their use is not systematically suggested. To reach the desired goals, patients should be actively involved in the collaborative development of a personalised meal plan associated with habitual physical activity, aiming at normal body weight and metabolic control.

Diabetes is common in patients wait-listed for liver transplantation due to end-stage liver disease or to hepatocellular cancer as well as in post-transplant phase (post-transplantation diabetes mellitus-PTDM). In both conditions the presence of diabetes severely affects disease burden and long-term clinical outcomes; careful monitoring and appropriate treatment are pivotal to reduce cardiovascular events and graft and recipients' death. We thoroughly reviewed the epidemiology of diabetes in the transplant setting and the different therapeutic options, from lifestyle intervention to antidiabetic drug use - including the most recent drug classes available - and to the inclusion of bariatric surgery in the treatment cascade. In wait-listed patients, the old paradigm that insulin should be the treatment of choice in the presence of severe liver dysfunction is no longer valid; novel antidiabetic agents may provide adequate glucose control without the risk of hypoglycemia, also offering cardiovascular protection. The same evidence applies to the post-transplant phase, where oral or injectable noninsulin agents should be considered to treat patients to target, limiting the impact of disease on daily living, without interaction with immunosuppressive regimens. The increasing prevalence of liver disease of metabolic origin (nonalcoholic fatty liver) among liver transplant candidates, also having a higher risk of noncirrhotic hepatocellular cancer, is likely to accelerate the acceptance of new drugs and invasive procedures, as suggested by international guidelines. Intensive lifestyle intervention programs remain however mandatory, both before and after transplantation. Achievement of adequate control is mandatory to increase candidacy, to prevent de-listing and to improve long-term outcomes.

Despite the fact that non-alcoholic fatty liver disease (NAFLD) and its severe clinical forms [non-alcoholic steatohepatitis (NASH) and NASH-cirrhosis] are highly prevalent in the general population, there are no licensed drugs for NAFLD, and lifestyle intervention remains the only treatment accepted by international guidelines. This is despite massive investments in research by pharmaceutical companies. In the presence of type 2 diabetes, novel anti-diabetic drugs offer an opportunity to reduce the burden of NAFLD, by adequate control of glucose and lipid metabolism, also reducing the risk of NASH progression, advanced fibrosis, and finally hepatocellular carcinoma. We extensively reviewed the literature, based either on registration studies, ad hoc randomized studies or real-world data, to define the effectiveness of anti-diabetic drugs in the treatment of NAFLD and prevention of hepatocellular carcinoma (HCC). Metformin provides the best evidence for decreased risk of HCC, pioglitazone was associated with decreased progression to fibrosis, glucagon-like peptide-1 receptor agonists offer a possible opportunity to reduce NAFLD progression coupled with a definite protection for cardiovascular outcomes, and sodium-glucose cotransporter-2 inhibitors are likely to reduce lipid burden, simultaneously reducing the risk of progressive renal and heart failure. For the latter two drug classes, the effects on NAFLD might largely explained by decreased body weight, in keeping with the beneficial effects of intensive lifestyle intervention.

Rationale: The prevalence of malnutrition and the provided nutritional therapy were evaluated in all the patients with SARS-CoV-2 infection (COVID-19) hospitalized in a 3rd level hospital in Italy. Methods: A one-day audit was carried out recording: age, measured or estimated body weight (BW) and height, body mass index (BMI, kg/m2), 30-day weight loss (WL), comorbidities, serum albumin and C-reactive protein (CRP: nv < 0.5 mg/dL), hospital diet (HD) intake, oral nutritional supplements (ONS), enteral (EN) and parenteral nutrition (PN). Modified NRS-2002 tool and GLIM criteria were used for nutritional risk screening and for the diagnosis of malnutrition, respectively. Results: A total of 268 patients was evaluated; intermediate care units (IMCUs, 61%), sub-intensive care units (SICUs, 8%), intensive care units (ICUs, 17%) and rehabilitation units (RUs, 14%): BMI: 0.5: 78% (higher in ICUs and lower in RUs, p < 0.001); Nutritional risk and malnutrition were present in 77% (higher in ICUs and RUs, p < 0.001) and 50% (higher in ICUs, p = 0.0792) of the patients, respectively. HD intake ≤50%, 39% (higher in IMCUs and ICUs, p < 0.001); ONS, EN and PN were prescribed to 6%, 13% and 5%, respectively. Median energy and protein intake/kg BW were 25 kcal and 1.1 g (both lower in ICUs, p < 0.05) respectively. Conclusions: Most of the patients were at nutritional risk, and one-half of them was malnourished. The frequency of nutritional risk, malnutrition, disease/inflammation burden and decrease intake of HD differed among the intensity of care settings, where the patients were managed according to the severity of the disease. The patient energy and protein intake were at the lowest limit or below the recommended amounts, indicating the need for actions to improve the nutritional care practice.

Introduction: Fatty liver is rather common in pregnancy, occurring in two totally different conditions, i.e. nonalcoholic fatty liver disease (NAFLD) in pregnancy and acute fatty liver of pregnancy (AFLP). The former is a common condition, resulting by chance association because of the epidemics of obesity and the older age of many pregnant women in Western countries; the latter is a rare disease whose pathophysiology is still incompletely understood. Areas covered: We reviewed the evidence-based knowledge on fatty liver in/of pregnancy. For NAFLD, a few large retrospective and prospective studies identify immediate and late risks for both the mother and the fetus. For AFLP, only small retrospective studies are available, indicating that prompt delivery and eventual referral to Liver Units for liver support or transplantation are mandatory to avoid maternal and fetal death. Expert opinion: The number of pregnant women with fatty liver is expected to increase in the next years. Pharmacologic treatment of NAFLD might be postponed, even when new drugs are approved by health authorities for the general population. In the case of AFLP, we need to improve our ability to correctly identify and treat the most severe cases not resolving with delivery.

Obesity—namely visceral obesity—is definitely the core of the metabolic syndrome, having insulin resistance as the central metabolic defect. Body fat accumulation and insulin resistance mutually feed each other, and progressive lipotoxicity, i.e., accumulation of fat in adipose tissue stores, finally involves several organs, including the liver. The primary defect may be genetic in origin, or promoted by epigenetic modifications, or, more commonly, by unhealthy lifestyles (both unhealthy diet and poor physical activity), progressively leading to obesity. Nonalcoholic fatty liver disease is one of such conditions, possibly further impairing insulin sensitivity and favoring other comorbidities. The presence of “lean NAFLD” does not confute this theory: it must be regarded as a condition with a much more genetic imprinting in subjects who long maintain an adequate lifestyle. However, in most cases, favored by the accumulation of body fat and reduced physical activity that are common along the years, also these subjects are prone to develop visceral obesity. They might be considered “metabolically unhealthy normal weight” subjects, as opposed to the “metabolically healthy obese” individuals. In most cases, a variable drive of genes and lifestyle is probably the basis for differences that tend to produce obesity and metabolic diseases, including NAFLD, in the course of life.

Background and aims Phenylketonuria (PKU)-affected women may become pregnant, and dietary phenylalanine (Phe) intake must be adjusted according to Phe tolerance. We report our experience with maternal PKU in relation to genotype PKU heterogeneity. Methods and Results A total of 10 pregnancies in 7 PKU women (7 different genotypes) were followed up as part of personalized care. Phe tolerance during preconception and pregnancy was assessed by strict dietary control and weekly Phe measurement (blood spots) in relation to genotype. Most women had stopped PKU diet during childhood or adolescence and six pregnancies were unplanned; a phenylalanine-restricted diet was reinstituted soon after conception. Women were classified according to their Phe levels at birth screening and genotype. Phe tolerance increased systematically in the course of pregnancy in all cases, but the increase was different in subjects with classic PKU (cPKU) when compared with cases with mild hyperphenylalaninemia (mHPA), both on average (+297 mg/day in cPKU vs. 597 in mHPA; P = 0.017) and as percentage (+107% in cPKU vs. +17% in mHPA). Notably, Phe tolerance also varied in the same women in the course of different pregnancies, when body weight gain was also different. Two newborns from the same cPKU mother (unplanned pregnancies on free diet) were affected by congenital alterations. Conclusions Several factors influence metabolic phenotype in maternal PKU, to an unpredictable extent even in the same woman. The number of maternal PKU cases is growing in dedicated Nutrition Units, and the burden associated with careful management of this condition for the health care system should be adequately considered.

Background: Lifestyle interventions aimed at weight loss have been associated with improved liver enzymes, reduced intrahepatic triglyceride content, and improved histology (including reduced fibrosis stage). Objective: To revise the evidence on the beneficial effects of lifestyle changes accumulated since 2015, following the publication of the pivotal Cuban experience with histologic outcome. Methods: A PubMed search covering the period 2015 to July 2019 was carried out. All retrieved references were analyzed and double-checked by authors. Results: 20 new studies were identified; in addition, two relevant studies provided new evidence. Thirteen studies were classified as randomized, controlled studies, three as proof-of-concept/pilot studies, four as cohort observational studies. In an attempt to maintain a closer contact between participants and the treatment center, a study implemented regular phone calls, another an e-mail service, a third was based on text messages, and finally, a study was totally web-based. Notably, the web-based treatment, accessed following intense motivational interviewing, was not less effective than a standard group-based behavior program. Conclusion: Lifestyle changes should form the basis of any NAFLD intervention. Information technology provides the opportunity to expand treatment, bypassing job and time constraints in younger patients, and to maintain long-term contact between patients and therapists in the NAFLD population.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and its prevalence is increasing in relation to the epidemics of obesity and type 2 diabetes mellitus, via non-alcoholic fatty liver disease (NAFLD). Unhealthy lifestyles associated with metabolic disorders are per se risk conditions for NAFLD progression, and specific gene polymorphisms may also favor oncogenesis, particularly in the presence of advanced fibrosis or cryptogenic cirrhosis. However, NAFLD-associated HCC may also develop in non-cirrhotic NAFLD and is frequently diagnosed at a more advanced tumor stage, compared with virus/alcohol-related HCC. This highlights the need for screening programs and long-term surveillance for earlier HCC detection in patients with metabolic risk factors, a policy hindered by the large number of cases at risk, with costs unaffordable by National health systems. New screening tools and cost-utility studies are eagerly awaited to develop more appropriate programs for early detection and treatment of NAFLD-associated HCC.

Non-alcoholic fatty liver disease is a very common medical condition, driven by a combination of genetic and lifestyle factors, ultimately producing a severe chronic liver disease and increased cardiovascular risk. Most people are asymptomatic for a long time, and their daily life is unaffected, leading to difficulty in identifying and managing people who slowly progress to non-alcoholic steatohepatitis (NASH), NASH-cirrhosis, and eventually hepatocellular carcinoma. Despite advances in the understanding of pathogenic mechanisms and the identification of liver fibrosis as the strongest factor in predicting disease progression, no specific treatments have been approved by regulatory agencies. Outside controlled trials, treatment is generally limited to lifestyle intervention aimed at weight loss. Pioglitazone remains the drug of choice to reduce progression of fibrosis in people with diabetes, although it is often used off-label in the absence of diabetes. Vitamin E is mainly used in children and may be considered in adults without diabetes. Several drugs are under investigation according to the agreed targets of reduced NASH activity without worsening of fibrosis or improving fibrosis without worsening of NASH. Anti-inflammatory, anti-fibrotic agents and metabolism modulators have been tested in either phase III or phase IIb randomized controlled trials; a few failed, and others have produced marginally positive results, but only a few are being tested in extension studies. The development of non-invasive, easily repeatable surrogate biomarkers and/or imaging tools is crucial to facilitate clinical studies and limit liver biopsy.

Background: The accumulation of fat droplets in the hepatic parenchyma is driven by several factors, synergistically acting to increase triglyceride flow to the liver (diet and metabolic factors, endotoxemia from gut microbiota, genetic factors). Key Messages: In the presence of unhealthy lifestyles and behavioral factors, leading to enlarged adipose tissue and insulin resistance (IR), both lipolysis and de novo lipogenesis are expected to increase the risk of hepatic lipid depots, in association with high calorie (either high-fat or high-carbohydrate) diets. The gut microbiota may also be involved via obesity, IR and hepatic inflammation generated by gut-derived toxic factors. Finally, several data also support a primary role of genetic factors. A few gene polymorphisms have also been associated with the risk of nonalcoholic fatty liver disease development and nonalcoholic steatohepatitis progression to more fibrosis and advanced liver disease. In a few cases (e.g., patatin-like phospholipase domain-containing 3/adiponutrin), steatosis carries a high risk of both liver disease and cardiovascular morbidity/mortality; in other cases (e.g., transmembrane 6 superfamily 2 human gene), dissociation has been observed between the increased risk of liver disease versus cardiovascular disease. Conclusions: A variable interplay between the genetic background and the metabolic milieu is the likely physiopathologic mechanism involved in individual cases, which must be considered for implementing effective treatment strategies.

Background & Aims Interventions aimed at lifestyle changes are pivotal for the treatment of non-alcoholic fatty liver disease (NAFLD), and web-based programs might help remove barriers in both patients and therapists. Methods In the period 2010–15, 716 consecutive NAFLD cases (mean age, 52; type 2 diabetes, 33%) were treated in our Department with structured programs. The usual protocol included motivational interviewing and a group-based intervention (GBI), chaired by physicians, dietitians and psychologists (five weekly meetings, n = 438). Individuals who could not attend GBI entered a web-based intervention (WBI, n = 278) derived from GBI, with interactive games, learning tests, motivational tests, and mail contacts with the center. The primary outcome was weight loss ≥10%; secondary outcomes were alanine aminotransferase within normal limits, changes in lifestyle, weight, alanine aminotransferase, and surrogate markers of steatosis and fibrosis. Results GBI and WBI cohorts had similar body mass index (mean, 33 kg/m2), with more males (67% vs. 45%), younger age, higher education, and more physical activity in the WBI group. The two-year attrition rate was higher in the WBI group. Healthy lifestyle changes were observed in both groups and body mass index decreased by almost two points; the 10% weight target was reached in 20% of WBI cases vs. 15% in GBI (not significant). In logistic regression analysis, after adjustment for confounders and attrition rates, WBI was not associated with a reduction of patients reaching short- and long-term 10% weight targets. Liver enzymes decreased in both groups, and normalized more frequently in WBI. Fatty liver index was reduced, whereas fibrosis remained stable (NAFLD fibrosis score) or similarly decreased (Fib-4). Conclusion WBI is not less effective than common lifestyle programs, as measured by significant clinical outcomes associated with improved histological outcomes in NAFLD. eHealth programs may effectively contribute to NAFLD control. Lay summary In patients with non-alcoholic fatty liver disease, participation in structured lifestyle programs may be jeopardized by job and time constraints. A web-based intervention may be better suited for young, busy patients, and for those living far from liver units. The study shows that, following a structured motivational approach, a web-based, interactive intervention coupled with six-month face-to-face meetings is not inferior to a standard group-based intervention with respect to weight loss, adherence to healthy diet and habitual physical activity, normalization of liver enzymes, and stable surrogate markers of fibrosis.

Nonalcoholic fatty liver disease (NAFLD) is defined by hepatic steatosis in the presence of alcohol intake within safe limits, defined by guidelines of scientific associations (usually 20 g or 2 units/day in women, 30 g or 3 units in men). The diagnosis is usually followed by medical counseling of total abstinence, in order to prevent disease progression. This policy has been challenged by epidemiological studies, suggesting that the risk of liver disease and disease progression is lower in modest drinkers than in total abstainers. We revised the literature on the effects of modest alcohol intake on disease burden. Epidemiological data may suffer from several potential biases (recall bias for retrospective analyses, difficulties in the calculation of g/day), limiting their validity. Prospective data suggest that NAFLD patients with regular alcohol intake, although within the safe thresholds, are at higher risk of liver disease progression, including hepatocellular carcinoma; a detrimental effect of modest alcohol drinking is similarly observed in liver disease of viral etiology. Alcohol intake is also a risk factor for extrahepatic cancers, particularly breast, oral, and pharyngeal cancers, with gender difference and no floor effect, which outweigh the possible beneficial effects on cardiovascular system, also derived from retrospective studies. Finally, the negative effects of the calorie content of alcohol on dietary restriction and weight loss, the pivotal intervention to reduce NAFLD burden, should be considered. In summary, the policy of counseling NAFLD patients for alcohol abstinence should be maintained.

Summary Introduction Different DNA and RNA viruses exploit common strategies to support their persistence and replication in infected individuals. In particular, the hepatitis B virus (HBV) and the hepatitis C virus (HCV) cause major health problems worldwide. These pathogens exert an immunosuppressive role by inducing the persistent activation of cyclooxygenase-2 (COX-2) and an increased synthesis of prostaglandin E2 (PGE2). The suppression of this proinflammatory network by non-steroidal anti-inflammatory drugs (NSAIDs) has been proposed as a therapeutic approach to decrease viral replication. Materials and methods In this review, the role of inflammation in the support of viral replication and NSAIDs and ketoprofen pharmacology are briefly discussed. In addition, studies that have investigated the use of NSAIDs for the treatment of HBV and HCV chronic hepatitis, which were identified by a systematic literature search of PubMed and MEDLINE, are reported. Results To date, pegylated-interferon (PEG-IFN) and/or nucleot(s)ide analogues and PEG-IFN and ribavirin remain the standard therapy for HBV and HCV chronic hepatitis, respectively. Discussion The use of NSAIDs in patients with chronic viral hepatitis has only a “historical” interest. Nevertheless, the possible usefulness of ketoprofen with PEG-IFN and ribavirin for HCV-infected patients, non-responders to standard therapy or with genotype 1, should be evaluated in future clinical studies.

The long-term weight management of obesity remains a very difficult task, associated with a high risk of failure and weight regain. However, many people report that they have successfully managed weight loss maintenance in the long term. Several factors have been associated with better weight loss maintenance in long-term observational and randomized studies. A few pertain to the behavioral area (eg, high levels of physical activity, eating a low-calorie, low-fat diet; frequent self-monitoring of weight), a few to the cognitive component (eg, reduced disinhibition, satisfaction with results achieved, confidence in being able to lose weight without professional help), and a few to personality traits (eg, low novelty seeking) and patient–therapist interaction. Trials based on the most recent protocols of lifestyle modification, with a prolonged extended treatment after the weight loss phase, have also shown promising long-term weight loss results. These data should stimulate the adoption of a lifestyle modification-based approach for the management of obesity, featuring a nonphysician lifestyle counselor (also called “lifestyle trainer” or “healthy lifestyle practitioner”) as a pivotal component of the multidisciplinary team. The obesity physicians maintain a primary role in engaging patients, in team coordination and supervision, in managing the complications associated with obesity and, in selected cases, in the decision for drug treatment or bariatric surgery, as possible more intensive, add-on interventions to lifestyle treatment.

Many prognostic systems have been devised to predict the outcome of liver transplantation (LT) candidates. Today, the Model for End-Stage Liver Disease (MELD) is widely used for organ allocation, but it has shown some limitations. The aim of this study was to investigate the performance of MELD compared to 5 different score models. We evaluated the prognostic ability of MELD, modified Child-Turcotte-Pugh, MELD-sodium, United Kingdom MELD, updated MELD, and integrated MELD in 487 candidates with cirrhosis for LT at the Bologna Transplant Centre, Bologna, Italy, between 2003 and 2008. Calibration analysis by Hosmer-Lemeshow test, calibration curves, and concordance c-statistics (area under the receiver operating characteristic curve [AUC]) were calculated at 3, 6, and 12 months. Actual cumulative survival curves, taking into account the event of interest in the presence of competing risk, were obtained using the best cutoffs identified by AUC. For each score, the Hosmer-Lemeshow test revealed a good calibration. Integrated MELD showed calibration curves closer to the line of perfect predicting ability, followed by MELD-sodium at 3 months and modified Child-Turcotte-Pugh at 6 months. MELD-sodium AUCs at 3 and 6 months (0.798 and 0.765, respectively) and integrated MELD AUC at 6 months (0.792) were better than standard MELD (P < 0.05). Actual survival curves showed that these 2 scores were able to identify the patients with the highest drop-out risk. In conclusion, MELD-sodium and integrated MELD were the best prognostic models to predict drop-out rates among patients awaiting LT.

Background Bone marrow stem/progenitor cells seem to be effective in liver regeneration after tissue injury. Aim To evaluate the feasibility and safety of the mobilization and reinfusion of CD133+ stem/progenitor cells in patients with end-stage liver disease. Methods Autologous CD133+ stem/progenitor cells, mobilized with granulocyte-colony stimulating factor, were collected by leukapheresis and reinfused at increasing doses through the hepatic artery starting from 5 × 104/kg up to 1 × 106/kg. Results 16 subjects with Model for End-stage Liver Disease (MELD) score between 17 and 25 were enrolled, 14 mobilized an adequate number of CD133+ stem/progenitor cells and 12 were reinfused. No severe adverse events related to the procedure were reported. MELD score significantly worsened during mobilization in Child Turcotte Pugh-C patients. A significant improvement of liver function was observed 2 months after reinfusion (MELD 19.5 vs 16; P = 0.045). Overall, 5 patients underwent liver transplantation within 12 months from reinfusion and 2 died because of progressive liver failure. Conclusions CD133+ stem/progenitor cells reinfusion in patients with end-stage liver disease is feasible and safe. A worsening of liver function was observed during mobilization in Child Turcotte Pugh-C patients. The temporary improvement of MELD score after reinfusion suggests that stem cells therapy may be a “bridge to transplant” approach for these patients.

AIM: To evaluate the predictors of 10-year survival of patients with hepatitis C recurrence. /// METHODS: Data from 358 patients transplanted between 1989 and 2010 in two Italian transplant centers and with evidence of hepatitis C recurrence were analyzed. A χ 2, Fisher's exact test and Kruskal Wallis' test were used for categorical and continuous variables, respectively. Survival analysis was performed at 10 years after transplant using the Kaplan-Meier method, and a log-rank test was used to compare groups. A p level less than 0.05 was considered significant for all tests. Multivariate analysis of the predictive role of different variables on 10-year survival was performed by a stepwise Cox logistic regression./// RESULTS: The ten-year survival of the entire popu lation was 61.2%. Five groups of patients were identified according to the virological response or lack of a response to antiviral treatment and, among those who were not treated, according to the clinical status (mild hepatitis C recurrence, "too sick to be treated" and patients with comorbidities contraindicating the treatment). While the 10-year survival of treated and untreated patients was not different (59.1% vs 64.7%, p = 0.192), patients with a sustained virological response had a higher 10-year survival rate than both the "non-responders" (84.7% vs 39.8%, p < 0.0001) and too sick to be treated (84.7% vs 0%, p < 0.0001). Sustained virological responders had a survival rate comparable to patients untreated with mild recurrence (84.7% vs 89.3%). A sustained virological response and young donor age were independent predictors of 10-year survival./// CONCLUSION: Sustained virological response significantly increased long-term survival. Awaiting the interferon-free regimen global availability, antiviral treatment might be questionable in selected subjects with mild hepatitis C recurrence.

Pegylated-interferon-α (Peg-IFN) are part of chronic hepatitis C (CHC) treatment. Among several side effects, it can induce psychiatric symptoms (PS) which could require discontinuation. The aim of this study was to evaluate the incidence, onset and risk factors of PS and antiviral treatment adherence in CHC patients treated with Peg-IFN plus ribavirin (RBV). All consecutive patients who received antiviral therapy between 2005 and 2011 were subjected to a psychiatric assessment before and during treatment. Of them, 49.2% reported PS especially during the first 4 weeks. Irritability was the predominant symptom recorded. The baseline factors associated with a higher risk of developing PS were: age ≤ 50 years (OR=1.67, 95% CI=1.15-2.43), living in Northern Italy (OR=1.88, 95% CI=1.31-2.70), genotype 1 (OR=1.82, 95% CI=1.28-2.60), previous antiviral treatment (OR=1.53, 95% CI=1.07-2.19) and history of mental disorders (MD) (OR=2.32, 95%CI=1.50-3.58). There was no difference in terms of sustained virologic response (SVR) between patients with and those without a history of MD (p=0.129). On the contrary, SVR was lower in patients who developed PS compared to other ones (p

Background & Aims The model for end-stage liver disease (MELD) is used for organ allocation in liver transplantation (LT), but its prognostic performance is less accurate in patients with low score. We assess the outcome of patients with MELD 15.9. Conclusions In patients with low MELD (

Background & Aims: The immune impairment characterizing chronic hepatitis B (cHBV) infection is thought to be the consequence of persistent exposure to viral antigens. However, the immune correlates of different clinical stages of cHBV and their relation with different levels of HBsAg have not been investigated. The aim of the present study was to evaluate the relationship between HBV-specific T cells response and the degree of in vivo HBV control and HBsAg serum levels in HBeAg-HBeAb+ cHBV. Methods: Peripheral blood mononuclear cells from 42 patients with different clinical profiles (treatment-suppressed, inactive carriers and active hepatitis) of cHBV, 6 patients with resolved HBV infection and 10 HBV-uninfected individuals were tested with overlapping peptides spanning the entire HBV proteome. The frequency and magnitude of HBV-specific T cell responses was assessed by IFNc ELISPOT assay. Serum HBsAg was quantified with a chemiluminescent immunoassay. Results: The total breadth and magnitude of HBV-specific T cell responses did not differ significantly between the four groups. However, inactive carriers targeted preferentially the core region. In untreated patients, the breadth of the anti-core specific T cell response was inversely correlated with serum HBsAg concentrations as well as HBV-DNA and ALT levels and was significantly different in patients with HBsAg levels either above or below 1000 IU/mL. The same inverse association between anti-core T cell response and HBsAg levels was found in treated patients. Conclusions: Different clinical outcomes of cHBV infection are associated with the magnitude, breadth and specificity of the HBV-specific T cell response. Especially, robust anti-core T cell responses were found in the presence of reduced HBsAg serum levels, suggesting that core-specific T cell responses can mediate a protective effect on HBV control.

Introduction: The metabolic syndrome is frequently associated with liver disease; the presence of obesity and diabetes boost progression to liver cirrhosis. These conditions make lifestyle changes aiming weight loss, crucial for prevention and treatment. The Mediterranean Diet (MD) has proved to be the most useful tool for losing and maintaining weight, protecting from cardiovascular mortality. Aim: To evaluate calorie intake (CI) and adherence to MD in patients affected by liver disease, cared for in the setting of a Metabolic Unit, in relation to BMI and basal metabolic rate (BMR). Materials and Methods: We studied all patients referred to the Unit from October 2019 to March 2020 (n=60), 24% had a viral etiology, 74% dismetabolic and 2% other etiologies. For the stage of disease, 50.7% had hepatitis, 34% had a diagnosis of cirrhosis and 15.3% were transplanted. CI was determined by means of an in-house developed questionnaire ("QuantoMangioVeramente"-QMV), measuring the CI on the basis of 20 items; the Mediterranean Diet Score (MDS) was used for evaluating adherence to MD; BMR and body composition were assessed by bioimpedance analysis. Results: Males (66%), mean age 61.5 years (±8.9), 71% had diabetes, weight 84.6 kg (±18.5), BMI 30.9 kg/m2(±5.7), lean mass 58.2 kg (±10), total body water 48.7% (±5.4), fat mass 31.1% (±8.5), BMR 1607Kcal (±251), CI from QMV 1808Kcal (±589), 1331Kcal (±438) in females vs. 2020Kcal (±523) in males (p

For the last decade, the combination therapy of pegylated interferon (Peg-IFN) plus ribavirin (RBV) has been considered as the standard of care treatment for chronic hepatitis C virus (HCV) infection. However, it has been associated with an increased incidence of many adverse cutaneous reactions and emergence of autoantibodies or even autoimmune diseases. We report a case of irreversible alopecia universalis (AU) with complete hair loss extended to the whole body, which started after discontinuation of Peg-IFN/RBV combination therapy for chronic HCV infection. In conclusion, this case represents an uncommon presentation of a common disease. Physicians must be aware of the potential adverse reactions of an antiviral therapy containing IFN, which might occur even after the discontinuation, and fully inform the patient at the beginning of his treatment course. We hope that interferon-free regimens will utterly supplant interferon-based therapy for most or all HCV patients avoiding the emergence of autoimmune manifestations.
