Gut microbiota correlates with antitumor activity in patients with mCRC and NSCLC treated with cetuximab plus avelumab.

Gut microbiota is involved in immune modulation and immune checkpoint inhibitors (ICIs) efficacy. Single-arm phase II CAVE-mCRC and CAVE-LUNG clinical trials investigated cetuximab + avelumab combination in RAS wild-type (WT) metastatic colorectal cancer (mCRC) and chemo-refractory nonsmall cell lung cancer (NSCLC) patients, respectively. A comprehensive gut microbiota genetic analysis was done in basal fecal samples of 14 patients from CAVE-mCRC trial with circulating tumor DNA (ctDNA) RAS/BRAF WT and microsatellite stable (MSS) disease. Results were validated in a cohort of 10 patients from CAVE-Lung trial. 16S rRNA sequencing revealed 23 027 bacteria species in basal fecal samples of 14 patients from CAVE-mCRC trial. In five long-term responding patients (progression-free survival [PFS], 9-24 months) significant increases in two butyrate-producing bacteria, Agathobacter M104/1 (P = .018) and Blautia SR1/5 (P = .023) were found compared to nine patients with shorter PFS (2-6 months). A significantly better PFS was also observed according to the presence or absence of these species in basal fecal samples. For Agathobacter M104/1, median PFS (mPFS) was 13.5 months (95% confidence interval [CI], 6.5-20.5 months) vs 4.6 months (95% CI, 1.8-7.4 months); P = .006. For Blautia SR1/5, mPFS was 5.9 months (95% CI, 2.2-9.7 months) vs 3.6 months (95% CI, 3.3-4.0 months); P = .021. Similarly, in CAVE-Lung validation cohort, Agathobacter M104/1 and Blautia SR1/5 expression were associated with PFS according to their presence or absence in basal fecal samples. Agathobacter and Blautia species could be potential biomarkers of outcome in mCRC, and NSCLC patients treated with cetuximab + avelumab. These findings deserve further investigation.

Immunity as Cornerstone of Non-Alcoholic Fatty Liver Disease: The Contribution of Oxidative Stress in the Disease Progression.

Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome and has become the major cause of chronic liver disease, especially in western countries. NAFLD encompasses a wide spectrum of hepatic histological alterations, from simple steatosis to steatohepatitis and cirrhosis with a potential development of hepatocellular carcinoma. Non-alcoholic steatohepatitis (NASH) is characterized by lobular inflammation and fibrosis. Several studies reported that insulin resistance, redox unbalance, inflammation, and lipid metabolism dysregulation are involved in NAFLD progression. However, the mechanisms beyond the evolution of simple steatosis to NASH are not clearly understood yet. Recent findings suggest that different oxidized products, such as lipids, cholesterol, aldehydes and other macromolecules could drive the inflammation onset. On the other hand, new evidence indicates innate and adaptive immunity activation as the driving force in establishing liver inflammation and fibrosis. In this review, we discuss how immunity, triggered by oxidative products and promoting in turn oxidative stress in a vicious cycle, fuels NAFLD progression. Furthermore, we explored the emerging importance of immune cell metabolism in determining inflammation, describing the potential application of trained immune discoveries in the NASH pathological context.

Non-bismuth and bismuth quadruple therapies based on previous clarithromycin exposure are as effective and safe in an area of high clarithromycin resistance: A real-life study.

BACKGROUND: Bismuth quadruple (BQT) and non-bismuth quadruple (N-BQT) therapies are the recommended first-line treatments for Helicobacter (H.) pylori infection. OBJECTIVE: To compare the efficacy of BQT and N-BQT in clinical practice in an area with high clarithromycin resistance, choosing the regimen on the basis of previous exposure to clarithromycin. METHODS: A total of 404 consecutive H pylori-positive, naïve patients were enrolled. A total of 203 patients without previous exposure to clarithromycin received N-BQT, 100 patients for 10 days and 103 for 14 days, whereas 201 with previous exposure to clarithromycin received 10-day BQT. Efficacy and treatment-related adverse events were assessed. RESULTS AND CONCLUSIONS: Eradication rates by intention-to-treat analysis were 88.2% for N-BQT and 91.5% for BQT (P = .26); per-protocol analysis eradication rates were 91.2% and 95.8% for N-BQT and BQT, respectively (P = .07). Eradication rates were significantly higher with 14-day than 10-day CT (P < .003). Almost all patients had a good compliance with both N-BQT (95.6%) and BQT (95%). Adverse events occurred in 24.1% and 26.9% (P = .53) of patients in the N-BQT and BQT group, respectively. In conclusion, clarithromycin-containing non-bismuth or bismuth quadruple therapy, based on the knowledge of previous clarithromycin exposure, is effective and safe even in an area of high prevalence of clarithromycin-resistant H pylori strains.

Silybin-Induced Apoptosis Occurs in Parallel to the Increase of Ceramides Synthesis and miRNAs Secretion in Human Hepatocarcinoma Cells.

Silybin is a flavonolignan extracted from Silybum marianum (milk thistle) with hepatoprotective, antioxidant, and anti-inflammatory activity. Several studies have shown that silybin is highly effective to prevent and treat different types of cancer and that its antitumor mechanisms involve the arrest of the cell cycle and/or apoptosis. An MTT assay was performed to study cell viability, lipid peroxidation, extracellular NO production, and scavenger enzyme activity were studied by Thiobarbituric Acid-Reactive Species (TBARS) assay, NO assay, and MnSOD assay, respectively. Cell cycle and apoptosis analysis were performed by FACS. miRNA profiling were evaluated by real time PCR. In this study, we demonstrated that Silybin induced growth inhibition blocking the Hepg2 cells in G1 phase of cell cycle and activating the process of programmed cell death. Moreover, the antiproliferative effects of silybin were paralleled by a strong increase of the number of ceramides involved in the modulation of miRNA secretion. In particular, after treatment with silybin, miR223-3p and miR16-5p were upregulated, while miR-92-3p was downregulated (p < 0.05). In conclusion, our results suggest that silybin-Induced apoptosis occurs in parallel to the increase of ceramides synthesis and miRNAs secretion in HepG2 cells.

Silymarin/Silybin and Chronic Liver Disease: A Marriage of Many Years.

Silymarin is the extract of Silybum marianum, or milk thistle, and its major active compound is silybin, which has a remarkable biological effect. It is used in different liver disorders, particularly chronic liver diseases, cirrhosis and hepatocellular carcinoma, because of its antioxidant, anti-inflammatory and antifibrotic power. Indeed, the anti-oxidant and anti-inflammatory effect of silymarin is oriented towards the reduction of virus-related liver damages through inflammatory cascade softening and immune system modulation. It also has a direct antiviral effect associated with its intravenous administration in hepatitis C virus infection. With respect to alcohol abuse, silymarin is able to increase cellular vitality and to reduce both lipid peroxidation and cellular necrosis. Furthermore, silymarin/silybin use has important biological effects in non-alcoholic fatty liver disease. These substances antagonize the progression of non-alcoholic fatty liver disease, by intervening in various therapeutic targets: oxidative stress, insulin resistance, liver fat accumulation and mitochondrial dysfunction. Silymarin is also used in liver cirrhosis and hepatocellular carcinoma that represent common end stages of different hepatopathies by modulating different molecular patterns. Therefore, the aim of this review is to examine scientific studies concerning the effects derived from silymarin/silybin use in chronic liver diseases, cirrhosis and hepatocellular carcinoma.

Efficacy of 5-day levofloxacin-containing concomitant therapy in eradication of Helicobacter pylori infection.

BACKGROUND & AIMS: Helicobacter pylori have become resistant to antimicrobial agents, reducing eradication rates. A 10-day sequential regimen that contains levofloxacin was efficient, safe, and cost saving in eradicating H pylori infection in an area with high prevalence of clarithromycin resistance. We performed a noninferiority randomized trial to determine whether a 5-day levofloxacin-containing quadruple concomitant regimen was as safe and effective as the 10-day sequential regimen in eradicating H pylori in previously untreated patients. METHODS: We randomly assigned patients with H pylori infection to groups that were given 5 days of concomitant therapy (esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, levofloxacin 500 mg twice daily, and tinidazole 500 mg twice daily; n = 90) or 10 days of sequential therapy (esomeprazole 40 mg twice daily, amoxicillin 1g twice daily for 5 days followed by esomeprazole 40 mg twice daily, levofloxacin 500 mg twice daily, and tinidazole 500 mg twice daily for 5 more days; n = 90). Antimicrobial resistance was assessed by the E-test. Efficacy, adverse events, and costs were determined. RESULTS: Intention-to-treat analysis showed similar eradication rates for concomitant (92.2%; 95% confidence interval [CI], 84.0%-95.8%) and sequential therapies (93.3%; 95% CI, 86.9%-97.3%). Per-protocol eradication results were 96.5% (95% CI, 91%-99%) for concomitant therapy and 95.5% for sequential therapy (95% CI, 89.6%-98.5%). The differences between sequential and concomitant treatments were 1.1% in the intention-to-treat study (95% CI; -7.6% to 9.8%) and -1.0% in the per-protocol analysis (95% CI; -8.0% to 5.9%). The prevalence of antimicrobial resistance and incidence of adverse events were comparable between groups. Concomitant therapy cost $9 less than sequential therapy. CONCLUSIONS: Five days of levofloxacin-containing quadruple concomitant therapy is as effective and safe, and less expensive, in eradicating H pylori infection than 10 days of levofloxacin-containing sequential therapy.

The use of bicarbonate-sulphate-calcium-magnesium and sodium-low drinkable water improves functional gastrointestinal symptoms in patients with non-alcoholic fatty liver disease: A prospective study.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease is increasingly gaining epidemiological ground in liver diseases. Among the proposed non-pharmacologic interventions, dietary interventions have been widely used. Several patients suffering from it complain of gastrointestinal symptoms unrelated to organic gastrointestinal tract disease. However, the role of drinking water quality modifications in this regard has not been investigated in depth. METHODS: Patients with upper or lower functional gastrointestinal symptoms were enrolled and divided into groups based on bright liver ultrasound relief's presence (SP) or absence (NSP). These patients were asked to drink bicarbonate-sulphate-calcium-magnesium and sodium-low drinkable water (Fonte Essenziale ®) for six months. Participants were assessed at baseline (T0), at the end of six months of drinking water intake (T6), and after an additional six months of washout (T12) by questionnaires designed to evaluate lower and upper gastrointestinal symptoms (Leeds dyspepsia score, short form) severity and frequency. RESULTS: A total of 61 patients were enrolled. In the SP population, the severity of lower gastrointestinal symptoms improved between T0-T6 (Z: -2.437; ES: 0.312) and worsened after the water washout (Z: -2.492; ES: 0.319). The same was for the Leeds score severity sub score in T0-T6 (Z: -2.850; ES: 0.364) and T6-T12 (Z: -2.921; ES: 0.374). These improvements seem unrelated to the severity of liver steatosis at baseline. Furthermore, no safety issues were recorded while taking the water nor during the six-month follow-up afterwards. CONCLUSION: Regular six-month intake of 400 mL of Fonte Essenziale® water was associated, in the absence of dietary regimen modifications, with an improvement in some qualitative and quantitative features of upper and lower functional gastrointestinal symptoms in both an SP and NSP sample.

Herbal products: benefits, limits, and applications in chronic liver disease.

Complementary and alternative medicine soughts and encompasses a wide range of approaches; its use begun in ancient China at the time of Xia dynasty and in India during the Vedic period, but thanks to its long-lasting curative effect, easy availability, natural way of healing, and poor side-effects it is gaining importance throughout the world in clinical practice. We conducted a review describing the effects and the limits of using herbal products in chronic liver disease, focusing our attention on those most known, such as quercetin or curcumin. We tried to describe their pharmacokinetics, biological properties, and their beneficial effects (as antioxidant role) in metabolic, alcoholic, and viral hepatitis (considering that oxidative stress is the common pathway of chronic liver diseases of different etiology). The main limit of applicability of CAM comes from the lacking of randomized, placebo-controlled clinical trials giving a real proof of efficacy of those products, so that anecdotal success and personal experience are frequently the driving force for acceptance of CAM in the population.

Just Drink a Glass of Water? Effects of Bicarbonate-Sulfate-Calcium-Magnesium Water on the Gut-Liver Axis.

Background and Aim: Fonte Essenziale® water is a bicarbonate-sulfate-calcium-magnesium water, low in sodium, recognized by the Italian health care system in hydropinotherapy and hepatobiliary dyspepsia therapy. We wanted to explore its effects on the gut-liver axis and microbiota in non-alcoholic fatty liver disease patients. Patients and Methods: We considered enrollment for 70 patients, of which four were excluded. We finally enrolled 55 patients with ultrasound-documented steatosis (SPs+) and 11 patients without it (SPs-). They then drank 400 ml of water for 6 months in the morning on an empty stomach. Routine hematochemical and metabolic parameters, oxidative stress parameters, gastrointestinal hormone levels, and fecal parameters of the gut microbiota were evaluated at three different assessment times, at baseline (T0), after 6 months (T6), and after a further 6 months of water washout (T12). We lost, in follow-up, 4 (T6) and 22 (T12) patients. Results: Between T0-T6, we observed a significant Futuin A and Selenoprotein A decrease and a GLP-1 and PYY increase in SPs+ and the same for Futuin A and GLP-1 in SPs-. Effects were lost at T12. In SPs+, between T0-T12 and T6-12, a significant reduction in Blautia was observed; between T0-T12, a reduction of Collinsella unc. was observed; and between T0-T12 and T6-12, an increase in Subdoligranulum and Dorea was observed. None of the bacterial strains we analyzed varied significantly in the SPs- population. Conclusion: These results indicate beneficial effects of water on gastrointestinal hormones and hence on the gut-liver axis in the period in which subjects drank water both in SPs- and in SPs+.

Anorectal Function with High-Resolution Anorectal Manometry in Active Ulcerative Colitis and after Remission: A Pilot Study.

BACKGROUND: Ulcerative colitis may impair anorectal function, causing disabling symptoms such as incontinence and/or increase in the stool frequency, urgency and tenesmus. Data on anorectal function in these patients evaluated by conventional anorectal manometry are conflicting. OBJECTIVES: The aim of this prospective study was to assess by means of high resolution anorectal manometry the anorectal function in patients with mild-to-moderate ulcerative colitis at presentation and after remission. Anorectal function of ulcerative colitis patients was compared to that observed in healthy volunteers. METHODS: 20 patients with mild to moderate left-sided ulcerative colitis or proctitis and 20 healthy volunteers were prospectively enrolled. All ulcerative colitis patients underwent high resolution anorectal manometry before treatment and after clinical remission. RESULTS: Ulcerative colitis patients showed similar values for anal sphincter function as healthy volunteers, whereas rectal threshold volume for the first sensation, desire to defecate, urgency to defecate and maximum discomfort were significantly lower than in healthy volunteers (p<0.05). Rectal compliance was significantly lower in ulcerative colitis than in healthy volunteers (p<0.05). After remission, rectal threshold volumes, as well as rectal compliance, significantly increased. An inverse linear correlation was found between regression of urgency and stool frequency and rectal compliance (r=0.811; p<0.05). CONCLUSION: Ulcerative colitis patients show altered rectal function, with increased rectal sensitivity and lower compliance, compared to controls. This altered function is restored after successful treatment of the underlying inflammatory process. Finally high resolution anorectal manometry provides useful information on anorectal functionality and, in our opinion, should be preferred over conventional manometry.

The analysis of alcohol consumption during the severe acute respiratory syndrome Coronavirus 2 Italian lockdown.

BACKGROUND: The SARS-CoV-2 lockdown resulted in deep changes of lifestyles, promoting in many people the onset of psychological symptoms generally associated with drug and alcohol abuse. The aim of this study was to assess the variation of alcohol drinking habits in a sample of Italian citizens during lockdown and to identify the psychosocial factors surrounding it. METHODS: An online anonymous questionnaire was created and submitted from April 9 to April 28, 2020. Questions were related to personal psychosocial details and alcohol drinking habits during the lockdown, including Alcohol Use Disorders Identification Test (AUDIT C) questions. RESULTS: On a total of 1234 surveys the increase of both anxiety and fear was largely detected (63% and 61% respectively). The 18% increased alcohol consumption during the lockdown and it showed a significant correlation with anxiety and fear experienced (both P<0.001). The relative risk for 7 to 9 and more than 10 drinks per day consumption were directly linked to these symptoms (P<0.001). The most involved categories of participants showed this harmful association were self-employed workers and participants who live alone, subject aged 30-50 with high level of instruction or students, and not occupied people in the age range 18-19 (all P<0.001). Additionally, the subset of the study population that showed low alcohol consumption before the lockdown has demonstrated the worsening of alcohol assumption during the quarantine (P<0.0001). CONCLUSIONS: Several psychosocial factors are involved in determining the increase of alcohol consumption during lockdown and need the healthcare support to avoid awful impact on human life.

Alcoholic Consumption of Young Italians During the SARS-CoV-2 Pandemic.

BACKGROUND: The international health emergency caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which, at the end of 2019, hit the world, forced the governments of all countries to adopt stringent restrictive measures to contain the spread of the virus. Several studies have revealed worsening levels of anxiety, depression and perceived stress related to these restrictions and the resulting lifestyle changes. Some studies have also confirmed the presence of a relationship between SARS-CoV-2-related emotional distress and drinking behavior. Indeed, is a wellknown fact that alcohol consumption is one of the behavioral strategies used to reduce negative emotional states. However, it was documented that young people developed different responses to alcohol use during the pandemic than adults. OBJECTIVE: The aim of this work was to investigate the consumption habits of young Italians and how the consumption and purchase of alcoholic beverages have changed following the pandemic. New ways of drinking alcohol were also interesting to observe, such as online. METHODS: Young people between 18 and 35 years old were subjected to an anonymous questionnaire of 22 questions on the adoption of forms of behavior at risk through alcohol consumption, the quantity and occasions of preferential consumption, and on the methods and quantities of alcoholic beverage purchase, before and during the SARS-CoV-2 pandemic. The subjects who declared themselves "non-drinkers" were not included in the statistical survey. RESULTS: About 33% of the enrolled "drinkers" (268/823), adopted risky forms of alcoholic behavior. Males reported a higher average habit of drinking wine or alcohol (M = 1.9953 ± 1.39743, F = 1.7373 ± 1.36688, p <0.005); an increased frequency of drinking (M = 2.3025 ± 0.80610 F = 2.0494 ± 0.75043 p <0.001); a higher average number of drinks consumed (M = 1.5182 ± 0.85646, F = 1.2618 ± 0.53292, p <0.001) and binge drinking to the greatest extent (M = 1.1933 ± 0.96522 F = 0.8176 ± 0.85446 p <0.001). Education and employment were significantly correlated with the frequency of alcohol consumption (r = 0.107 p <0.005 and r = 0.120 p = 0.001 respectively). Subjects reported buying alcoholic beverages during the pandemic with a frequency of "less than once a month" (N = 291, 35.36%) and mainly in shops (N = 556, 67.56%), while before the pandemic they mainly bought alcohol once a week (N = 431, 52.37%) and predominantly in bars / clubs (N = 619, 75.21%). New ways of drinking alcohol such as online drinking, have not been significantly identified. CONCLUSION: A change in alcohol consumed and alcohol purchased before and during the SARSCoV- 2 pandemic was revealed.

The Lesson from the First Italian Lockdown: Impacts on Anxiety and Depressive Symptoms and Sleep Quality in Patients with Remission of Inflammatory Bowel Disease.

BACKGROUND: During the COVID-19 pandemic in Italy, decisions were taken to adopt restrictive legislative measures, such as the first half of the 2020 lockdown. In those months, patients with inflammatory bowel disease experienced social isolation and reduced access to health care. OBJECTIVE: We aimed to evaluate, in this condition, the presence of remission subgroups that were most impacted by the lockdown. METHODS: During the first Italian lockdown, we recruited patients with remission of inflammatory bowel disease by administering an online questionnaire including patient demographics, the Beck Anxiety Questionnaire Inventory, the Beck Depression Inventory questionnaire, and the Pittsburg Sleep Quality Index, all validated standardized questionnaires for anxiety symptom levels, depression, and sleep quality. RESULTS: Our results showed how female patients (p<0.0001) with Crohn's disease (p<0.001) experienced worse levels of anxiety symptoms. Female patients (p<0.0001) between 50 and 60 years of age (p=0.013) with Crohn's disease (p=0.047) experienced worse levels of depressive symptoms. Females also experienced significantly worse sleep levels (p<0.001). We found a correlation between the number of sleeping hours (p<0.001) and the time taken to fall asleep (p<0.001) and the Beck Anxiety Questionnaire Inventory,which showed a linear worsening of the number of minutes it took to fall asleep, and the Beck Depression Inventory questionnaire. CONCLUSION: Among patients with remission of inflammatory bowel disease, female patients, patients with Crohn's disease, and people aged between 50 and 70 years should be considered for screening for anxiety and depression disorders and an assessment of sleep quality.

Evaluation of the Efficacy and Safety of a Compound of Micronized Flavonoids in Combination With Vitamin C and Extracts of Centella asiatica, Vaccinium myrtillus, and Vitis vinifera for the Reduction of Hemorrhoidal Symptoms in Patients With Grade II and III Hemorrhoidal Disease: A Retrospective Real-Life Study.

Background and Aim: Several evidences have shown how, in hemorrhoidal disease, phlebotonic flavonoid agents such as quercetin reduce capillary permeability by increasing vascular walls resistance, how rutin and vitamin C have antioxidant properties, and that Centella asiatica has reparative properties towards the connective tissue. A retrospective study was designed in order to evaluate the efficacy and safety of a compound consisting of micronized flavonoids in combination with vitamin C and extracts of C. asiatica, Vaccinium myrtillus, and Vitis vinifera for grade II and III hemorrhoidal disease. Patients and Methods: Data of 49 patients, over 18, who were following a free diet regimen, not on therapy with other anti-hemorrhoid agents, treated with a compound consisting of 450 mg of micronized diosmin, 300 mg of C. asiatica, 270 mg of micronized hesperidin, 200 mg of V. vinifera, 160 mg of vitamin C, 160 mg of V. myrtillus, 140 mg of micronized quercetin, and 130 mg of micronized rutin (1 sachet or 2 tablets a day) for 7 days were collected. Hemorrhoid grade according to Goligher's scale together with anorectal symptoms (edema, prolapse, itching, thrombosis, burning, pain, tenesmus, and bleeding) both before treatment (T0) and after 7 days of therapy (T7) were collected. Primary outcomes were the reduction of at least one degree of hemorrhoids according to Goligher's scale assessed by proctological examination and compound safety. The secondary outcome was the reduction of anorectal symptoms assessed by questionnaires administered to patients. Results: Forty-four patients (89.8%) presented a reduction in hemorrhoidal grade of at least one grade (p < 0.001). No adverse events with the use of the compound were noted. A significant reduction was observed in all anorectal symptoms evaluated (p < 0.05). No predictors of response to the compound were identified among the clinical and demographic variables collected. Conclusion: The compound analyzed was effective and safe for patients with grade II and III hemorrhoidal disease according to Goligher's scale.

Nutrigenomics and Nutrigenetics in Metabolic- (Dysfunction) Associated Fatty Liver Disease: Novel Insights and Future Perspectives.

Metabolic- (dysfunction) associated fatty liver disease (MAFLD) represents the predominant hepatopathy and one of the most important systemic, metabolic-related disorders all over the world associated with severe medical and socio-economic repercussions due to its growing prevalence, clinical course (steatohepatitis and/or hepatocellular-carcinoma), and related extra-hepatic comorbidities. To date, no specific medications for the treatment of this condition exist, and the most valid recommendation for patients remains lifestyle change. MAFLD has been associated with metabolic syndrome; its development and progression are widely influenced by the interplay between genetic, environmental, and nutritional factors. Nutrigenetics and nutrigenomics findings suggest nutrition's capability, by acting on the individual genetic background and modifying the specific epigenetic expression as well, to influence patients' clinical outcome. Besides, immunity response is emerging as pivotal in this multifactorial scenario, suggesting the interaction between diet, genetics, and immunity as another tangled network that needs to be explored. The present review describes the genetic background contribution to MAFLD onset and worsening, its possibility to be influenced by nutritional habits, and the interplay between nutrients and immunity as one of the most promising research fields of the future in this context.

PNPLA3, TM6SF2, and MBOAT7 Influence on Nutraceutical Therapy Response for Non-alcoholic Fatty Liver Disease: A Randomized Controlled Trial.

Introduction: PNPLA3, TM6SF2, and MBOAT7 genes play a crucial role in non-alcoholic fatty liver disease (NAFLD) development and worsening. However, few data are available on their treatment response influence. The aim of this trial is to explore the effect derived from silybin-phospholipids complex (303 mg of silybin-phospholipids complex, 10 µg of vitamin D, and 15 mg of vitamin E twice a day for 6 months) oral administration in NAFLD patients carrying PNPLA3-rs738409, TM6SF2-rs58542926, or MBOAT7-rs641738 genetic variants. Materials and Methods: In all, 92 biopsy-proven NAFLD patients were grouped in 30 NAFLD wild type controls, 30 wild type treated patients, and 32 mutated treated ones. We assessed glycemia (FPG), insulinemia, HOMA-IR, aspartate and alanine aminotransferases (AST, ALT), C-reactive protein (CRP), thiobarbituric acid reactive substance (TBARS), stiffness, controlled attenuation parameter (CAP), dietary daily intake, and physical activity at baseline and end of treatment. Results: The wild-type treated group showed a significant improvement of FPG, insulinemia, HOMA-IR, ALT, CRP, and TBARS (p < 0.05), whereas no improvements were recorded in the other two study groups. NAFLD wild type treated patients showed higher possibilities of useful therapeutic outcome (p < 0.01), obtained from the prescribed therapeutic regimen, independently from age, sex, comorbidities, medications, CAP, and stiffness in comparison to the mutated group. Discussion: The assessed mutations are independently associated with no response to a silybin-based therapeutic regimen and could be considered as useful predictive markers in this context.

Adherence and Effects Derived from FODMAP Diet on Irritable Bowel Syndrome: A Real Life Evaluation of a Large Follow-Up Observation.

INTRODUCTION: Irritable bowel syndrome represents one of the most difficult gastroenterological diseases to treat, that usually induces the patients to follow different drug therapies, often not useful in symptom control. In this scenario low FODMAP diet could have positive effects in patients with irritable bowel syndrome, even because this type of diet regimen is characterized by a low gluten amount due to the exclusion of cereals. METHODS: We enrolled 120 patients with irritable bowel syndrome, according to the Rome IV criteria, who were referred to Hepatogastroenterology Division of the University of Campania L. Vanvitelli from June to December 2018. They underwent a low FODMAP diet for six weeks, followed by a gradual weekly reintroduction of every category of food for three months. The patients had a follow-up evaluation for six months after the end of food reintroduction period. We measured abdominal pain with subjective numerical scale from 0 to 10. We evaluated other gastrointestinal symptoms with a questionnaire about symptoms of lower digestive tract, evaluating their frequency and intensity. We also evaluated the impact of irritable bowel syndrome on daily life with neurological bowel dysfunction score. RESULTS: We obtained a good patient-adherence to diet and a statistically significant decrease of abdominal pain, bloating, flatulence, diarrhea, constipation, and neurological bowel dysfunction score (p < 0.001) at the end of the diet. These results remained constant in the follow-up period. CONCLUSIONS: We recommend the use of a low FODMAP diet regimen in patients with irritable bowel syndrome in order to control the symptoms and improve the quality of life.

Alcohol associated liver disease 2020: A clinical practice guideline by the Italian Association for the Study of the Liver (AISF).

Alcohol use disorder which includes alcohol abuse and dependence represents one of the leading risk factors for premature mortality in Europe and it is responsible of over 200 conditions, including neuropsychiatric disorders, chronic diseases, cancers and accidents leading to permanent disability. Alcohol use disorder represents the most common cause of liver damage in the Western world, with a wide spectrum of diseases ranging from steatosis, steatohepatitis, fibrosis, cirrhosis and cancer. The present clinical practice guidelines by the Italian Association for the Study of the Liver (AISF) are focused on the current knowledge about epidemiology, pathophysiology, clinical features, diagnosis and treatment of alcohol associated liver disease, aiming to provide practical recommendations on the management of this complex pathological condition.

Cirrhosis and frailty assessment in elderly patients: A paradoxical result.

The frailty represents a key determinant of elderly clinical assessment, especially because it allows the identification of risk factors potentially modifiable by clinical and therapeutic interventions. The frailty assessment in elderly patients usually is made by using of Fried criteria. However, to assess the frailty in cirrhotic patients, multiple but different tools are used by researchers. Thus, we aimed to compare frailty prevalence in elderly patients with well-compensated liver cirrhosis and without cirrhosis, according to Fried criteria.Among 205 elderly patients screened, a total of 148 patients were enrolled. The patients were divided into 2 groups according to the presence/absence of well-compensated liver cirrhosis.After clinical examination with conventional scores of cirrhosis, all patients underwent anthropometric measurements, nutritional, biochemical, comorbidity, and cognitive performances. Frailty assessment was evaluated according to Fried frailty criteria.Unexpectedly, according to the Fried criteria, non-cirrhotic patients were frailer (14.2%) than well-compensated liver cirrhotic patients (7.5%). The most represented Fried criterion was the unintentional weight loss in non-cirrhotic patients (10.1%) compared to well-compensated liver cirrhotic patients (1.4%). Moreover, cumulative illness rating scale -G severity score was significantly and positively associated with frailty status (r = 0.234, P < .004). In a multivariate linear regression model, only female gender, body mass index and mini nutritional assessment resulted associated with frailty status, independently of other confounding variables.Despite the fact that elderly cirrhotic patients are considered to be frailer than the non-cirrhotic elderly patient, relying solely on "mere visual appearance," our data show that paradoxically non-cirrhotic elderly patients are frailer than elderly well-compensated liver cirrhotic patients. Thus, clinical implication of this finding is that frailty assessment performed in the well-compensated liver cirrhotic patient can identify those cirrhotic patients who may benefit from tailored interventions similarly to non-cirrhotic elderly patients.
