ABSTRACT
BACKGROUND: In recent years, improvement of Health-Related Quality of Life (HRQoL) in Ulcerative colitis (UC) has become a relevant measure for treatment efficacy. METHODS: We report results from a multicenter prospective study in Italy investigating HRQoL in adult patients with UC treated with golimumab (GLM). Patients who had shown clinical response after a 6-week induction phase (w0), were followed for an additional 48 weeks (w48) (total 54-week treatment). RESULTS: Of the 159 patients enrolled 90 completed the study. Compared to values at the beginning of treatment (n = 137), significant improvements were observed for mean total Inflammatory Bowel Disease Questionnaire (IBDQ) scores at w0 (168.5) and w48 (181.7). Patients with baseline PMS above the median tended to have greater improvements in IBDQ at w0 (OR 2.037, p = 0.033) and w48 (OR 3.292, p = 0.027). Compared to beginning of GLM treatment, the mean Full Mayo Score (FMS) decreased by 5.9 points at w48, while mean Partial Mayo Score (PMS) decreased by 3.9 points at w0 and by 4.9 points at w48. CONCLUSIONS: GLM improved HRQoL, disease activity and inflammatory biomarkers in UC patients with moderate-to-severely active disease. The greater the burden of disease activity at baseline, the greater the improvement of HRQoL after 24 and 48 weeks of treatment.

We described a case of IPEX syndrome successfully controlled with dupilumab, an anti-IL4 receptor alpha subunit inhibitor. IPEX syndrome is a rare and generally fatal genetic disorder characterized by immune dysregulation, polyendocrinopathy and enteropathy, mostly diagnosed in early childhood. Nonetheless, cases reported in the last 20 years demonstrated that IPEX clinical spectrum encompasses more than the classical triad of early-onset intractable diarrhea, type 1 diabetes and eczema. Atypical cases of IPEX include patients with late-onset of symptoms, single-organ involvement, mild disease phenotypes or rare clinical features. A 21-year-old caucasian man presented with immune dysregulation (hypereosinophilia and elevated IgE), protein-losing enteropathy, polyendocrinopathy (thyroiditis, osteoporosis, delayed puberty), weight loss, eczema manifestations and celiac disease. IPEX syndrome was diagnosed because of the presence of a hemizygous mutation in FOXP3 gene (c.543C>T (p.S181S) in the exon 5). During the course of the disease, the patient developed erosive proctitis, pyoderma gangrenosum, and erythema nodosum. Symptoms improved only after enteral and parenteral corticosteroid therapy and the patient soon developed steroid-dependence. Notwithstanding various therapies including azathioprine, sirolimus, tacrolimus, adalimumab, vedolizumab, the patient failed to achieve a good control of symptoms without steroids. Almost exclusive enteral nutrition with a hypoallergenic, milk-protein free, amino acid-based food for special medical purposes. He continued to lose weight (BMI 14.5 kg/m2) with a consequent high limitation of physical activity and a progressive worsening of the quality of life. In consideration of the poor response to conventional immunosuppressants and the presence of type 2 inflammatory manifestations, treatment with dupilumab at an initial dose of 600 mg, followed by a maintenance dose of 300 mg every other week, according to atopic dermatitis labeled dose, was started and combined to oral budesonide 6 mg/day and 6-mercaptopurine 75 mg/day. The patient experienced a rapid improvement in bowel and skin symptoms, leading to a progressive tapering of steroids. By our knowledge, this is the first report of IPEX syndrome successfully treated by antiIL-4/IL-13 therapy. In this case dupilumab demonstrated to be an effective, safe and steroid-sparing option.

OBJECTIVE: The management of Inflammatory Bowel Disease (IBD) has changed significantly in recent years, mainly due to the introduction of biologic medications, however, other factors may also have a role. The aim of this study was to evaluate the evolution of IBD admissions, including trends, modality of admission and rates of surgical intervention, in a tertiary care center. PATIENTS AND METHODS: Hospitalization of patients with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) were identified between 2000 and 2013, using ICD-9-CM codes for IBD, from our hospital database. The following parameters were evaluated for each admission: type of admission (ordinary vs. day care service), mode of admission (elective vs. emergency care, for ordinary admissions only), admission code, surgical procedures and complication rates. Comparison between pre- and post-biologic therapy introduction years was also performed. RESULTS: Between 2000 and 2013 a total of 8834 IBD-related admissions were recorded. Hospitalizations increased linearly reaching a peak in 2006, with a downward trend in the following years. The downward trend was especially marked for patients younger than 40 years. No significant differences in hospitalization trends between CD and UC were recorded. Disease flare represented the cause of hospitalization in approximately 50% of cases. Overall, 10.8% of patients underwent surgery with no difference between the two conditions. Complications occurred in 28.7% of admissions. CONCLUSIONS: Hospitalizations for IBD patients have decreased in recent years, especially in younger patients. However, a significant proportion of patients are still admitted to complete diagnostic workup, indicating the need to better implement outpatient services. A clear reduction in surgery occurrence over time could not be observed in our study.

OBJECTIVE: The role of nurses has great educational-scientific potential in COVID-19 vaccination. The aim of this work is to clarify whether the educational role of IBD nurses in vaccination is perceived by IBD patients. MATERIALS AND METHODS: A cross-sectional study was carried out, through a questionnaire, to evaluate how many IBD patients received health education about vaccinations from the dedicated nurses (IBD nurses). RESULTS: There were four hundred questionnaires, 310 patients (77.5%) answered all questions. The nurse does not appear to help educate patients on influenza vaccination (66.1%) or pneumococcal vaccination (81.6%). Disclosed patients have many doubts about the new COVID-19 vaccination (74.4%) and many seek information (74.8%) and think that the nurse can provide the necessary information (70%). CONCLUSIONS: IBD nurses do not seem very active in the vaccination education role, and they do not meet patients' expectations, which are conversely very high.

OBJECTIVE: Few models of transition have been proposed for inflammatory bowel disease (IBD). The aim of the present study is to evaluate the feasibility of a transition model and the predictive factors for success/failure. PATIENTS AND METHODS: Patients with low activity or remission IBD were enrolled. Proposed model: three meetings every four-six weeks: the first one in the pediatric center (Bambino Gesù Children's Hospital); the second one, in the adult center (Foundation Polyclinic University A. Gemelli), with pediatric gastroenterologists; the last one, in the adult center, with adult gastroenterologists only. Questionnaires included anxiety and depression clinical scale, self-efficacy, quality of life, visual-analogic scale (VAS). Transition was considered successful if the three steps were completed. RESULTS: Twenty patients were enrolled (range 18-25 years; M/F: 12/8; Ulcerative Colitis/Crohn's Disease 10/10); eight accepted the transition program, four delayed the process and eight refused. Patients who completed transition generated higher scores on the resilience scale, better scores on well-being perception, and had lower anxiety scores. Patients who failed transition were mostly women. The perceived utility of the transition program was scored 7.3 on a VAS scale. CONCLUSIONS: The proposed transition program seems to be feasible. Psychological scores may help in selecting patients and predicting outcomes.

Compositional and functional alterations of the gut microbiota are involved in the pathogenesis of several gastrointestinal diseases. Rifaximin is often used to induce disease remission due to its eubiotic effects on the gut microbiota. To investigate the correlation between changes in the gut microbiota composition and symptoms improvement in patients who present a clinical response to rifaximin treatment. Patients with ulcerative colitis (UC), Crohn's disease (CD), irritable bowel syndrome (IBS) and diverticular disease (DD) undergoing rifaximin treatment for clinical indication were enrolled in the study. Rifaximin was administered at the dose of 1,200 mg/day for 10 days. Faecal samples were collected at baseline and at the end of treatment; clinical improvement was assessed by Mayo score for UC, CD Activity Index (CDAI) for CD, IBS severity scoring system (IBS-SSS) for IBS and global symptomatic score (GSS) for DD. Twenty-five patients were included in the analysis and a clinical improvement was recorded for 10/25 (40%) of them. Microbial alpha diversity showed a slight increase in clinical responders (P=0.271), while it decreased in patients who did not improved (P=0.05). A significant post-treatment increase in Faecalibacterium abundance was observed in patients with a positive response (log2FC 1.959, P=0.042). Roseburia abundance decreased in both groups, whereas Ruminococcus decreased only in patients who clinically improved. Clinical improvement consequent to rifaximin treatment is associated with an increase in Faecalibacterium abundance. Achieving a positive shift in the gut microbiota composition seems a key event to obtain a clinical benefit from treatment.

OBJECTIVE: The vaginal microbiome is a dynamic environment, depending on the results of a complex interplay between microbiota and the host. In physiological conditions, Lactobacillus species are the most represented, regulating glycogen metabolism in order to maintain normal pH. Vaginal flora has been divided into five subtypes. Pattern recognition receptors are present on both squamous epithelial cells lining the vagina and columnar cells lining the upper female genital tract. They respond directly to bacterial product expressed by vaginal microbiome. The vagina contains different immune related cells and receptors which can recognize and react with the microbial environment. Altered microbiota and altered interplay between microbiota and immune system underlie several gynecologic diseases. MATERIALS AND METHODS: In this review, literature data related to vaginal microbiota, vaginal inflammation, immune system and menopause, preterm labor and miscarriage, were summarized. Relevant publications were retrieved from: PubMed, Medline, Scopus and Web of Science. RESULTS: The vaginal microbiome and the relationship with immune system has been analyzed in different gynecologic conditions. Menopause is associated to estrogen loss which causes vaginal atrophy, reduced abundance of Lactobacilli and increased amount of other bacterial species. Estrogens influence vaginal immunity through known and unknown mechanisms. In bacterial vaginosis (BV), due to many bacterial species, there has been found an inhibition of the chemotaxis and cytokine secretion. A decreased concentration of Lactobacilli seems to be playing a role in preterm labor as well as the increased levels of pro-inflammatory cytokines. Finally, the disequilibrium in the Th1/Th2 immune adaptive response, with a shift from Th2 to Th1, appears to be playing a role in miscarriage. CONCLUSIONS: The interplay between microbiota and the host closely involves the immune system. In particular, the vaginal microbiota is classically characterized by Lactobacilli even if vaginal microbiome of asymptomatic woman of reproductive age includes multiple aerobic and facultative or obligate anaerobic species. The role of microbiota and immune system in determining gynecological and obstetric events has been studied throughout recent years reaching new advancements. Therefore, additional studies are needed to better comprehend the complexity of the issue.

OBJECTIVE: Therapeutic strategies for Inflammatory Bowel Diseases (IBD: Crohn's disease and Ulcerative Colitis) have improved but the risk for HPV infection in patients under immunomodulatory/biologic treatment is unclear. Objective of the study is to identify the attitude of patients and caregivers to cervical screening. To determine the prevalence of HPV and cervical lesions in IBD patients receiving immunomodulatory/biological treatment. PATIENTS AND METHODS: IBD patients treated with immunomodulators were enrolled from November 2016 to September 2017, thanks to a multidisciplinary cooperation. A survey was administered to enrolled patients as well as to a selected network of IBD expert physicians. Patients who consented underwent gynecological examination, smear, HPV DNA test, colposcopy, vaginal and cervical microbiological swabs. RESULTS: 294 patients from AMICI Onlus Association, 119 patients from the hospital clinic, 30 doctors from national IBD centers participated to the survey. 19 patients from the IBD clinic underwent cervical screening. More than 90% of doctors consider their patients at risk of cervical cancer. A low prevalence of high-risk genotypes and related HPV lesions and an increased prevalence of bacterial vaginosis emerged in the studied population. CONCLUSIONS: Biological drugs could lead to a positive immunomodulation towards HPV infection. In IBD patients an alteration of the vaginal and intestinal microbiota seems to be coexisting.

OBJECTIVE: Gut microbiota has a key role in host metabolic regulation and immune response, and its dysbiosis represents one of the main causes of gastrointestinal diseases. In this scenario, Akkermansia muciniphila is a crucial player in keeping the integrity of the gastrointestinal tract. MATERIALS AND METHODS: This review focuses on the correlation between gut microbiota and intestinal homeostasis, primarily exploring A. muciniphila and its involvement in the development of metabolic disorders and gastrointestinal diseases. RESULTS: Akkermansia muciniphila belongs to the Verrucomicrobia phylum, and it colonizes the mucus layer in the gastrointestinal tract, representing 1 to 4% of the fecal microbiota. It stimulates mucosal microbial networks, and it improves intestinal barrier function, providing crucial host immunological responses. Several studies have demonstrated the possible involvement of A. muciniphila in the development of intestinal and metabolic disorders. Indeed, adipose and glucose metabolisms are influenced by A. muciniphila, and its levels inversely correlate to inflammatory conditions, such as inflammatory bowel disease, obesity, and diabetes. Conversely, its therapeutic administration decreases their development. CONCLUSIONS: A. muciniphila exerts a key role in the maintenance of intestinal health and in host metabolic modulation. Future studies could open new horizons towards its potential therapeutic applications in gastrointestinal and extra-intestinal diseases.

ABSTRACT
Intestinal permeability is the property that allows solute and fluid exchange between intestinal lumen and intestinal mucosa. Many factors could have major impact on its regulation, including gut microbiota, mucus layer, epithelial cell integrity, epithelial junction, immune responses, intestinal vasculature, and intestinal motility. Any change among these factors could have an impact on intestinal homeostasis and gut permeability. Healthy condition is associated to normal intestinal permeability whereas several intestinal and extra intestinal disease, like inflammatory bowel disease, irritable bowel syndrome, non-alcoholic fatty liver disease among others, are associated to increased intestinal permeability. This review aims to synthesize determinants on intestinal permeability and to report methodologies useful to the measurement of intestinal permeability in clinical practice as well as in research settings.

OBJECTIVE: the role of microbes and chronic inflammation in the pathogenesis of Alzheimer' disease (AD) has been postulated by many authors. On the other hand, several studies have reported the main role of H. pylori infection and/or GUT microbiota alteration in promoting chronic inflammation, thus possibly influencing both occurrence and evolution of AD. In this article, we analyze the most important and recent studies performed on this field both on humans and animals and provide possible pathogenic explanations. RESULTS: all main and most recent animal, human, epidemiological and in-silico studies, showed a role of H. pylori and/or dysbiosis in AD, mostly through the promotion of systemic chronic inflammation and/or by triggering molecular mimicry mechanisms. In particular, H. pylori infection seems to be related to a poorer cognitive performance. CONCLUSIONS: Indeed, bacteria have been shown to affect neurodegeneration by promoting inflammation, inducing molecular mimicry mechanisms and accumulation of Aß into the brain. These findings open the way for H. pylori eradicating trials and/or GUT microbiota remodulating strategies. Therefore, further studies are now needed in order to test whether antibiotics, pre and/or probiotics may exert a beneficial effect in the prevention of AD.

OBJECTIVE: Even if pancreatic pathologies, residual fibrosis, residual amount of parenchyma, and anastomotic patency are recognized as main causes of exocrine and glycemic impairment after pancreaticoduodenectomy (PD), few data are reported concerning the role of the different pancreatic remnant treatment techniques. The objective of the study is to assess and compare exocrine functionality, glycemic pattern, nutritional status, and quality of life (QoL) after PD between pancreaticojejunostomy (PJ) and pancreatic duct occlusion (PDO), both in an objective and a subjective manner. PATIENTS AND METHODS: Thirty-two patients (16 PJ and 16 PDO) were evaluated after a mean follow-up of 21 months after surgery. Exocrine insufficiency was objectively evaluated through the 13C-labelled mixed triglyceride breath test. Fasting glucose, fasting insulin, HbA1c and HOMA-IR values were used to assess glucose metabolism. For these two outcomes, anamnestic data were also collected. QoL was assessed with GIQLI, SF-36, EORTC-QLQ-C30, and EORTC-PAN-26 questionnaires. RESULTS: The 13C-labelled mixed triglyceride breath test detected a lipid digestive insufficiency in 56% of patients after PJ and 100% after PDO respectively (p = 0.007). However, no difference was observed between the two groups regarding postoperative necessity of substitutive pancreatic enzymes. Nutritional status, fasting plasma glucose, fasting insulin, HbA1c levels, HOMA-IR values and postoperative necessity of insulin or oral antidiabetic agents were comparable between the two groups. QoL measurements showed similar results. However, in the subdomains analysis, better outcomes were reported regarding digestive symptoms and physical functioning for PJ and PDO respectively. CONCLUSIONS: Even if an objective exocrine major impairment was evidenced after PDO, this result did not impact the need for a higher rate of postoperative substitutive enzymes. In terms of glycemic pattern, nutritional status, and QoL, the two techniques turn out to be comparable.

BACKGROUND: Recurrent pregnancy loss (RPL) occurs in 3-5% in about 30% of cases no cause can be found. Women with RPL show higher prevalence of undiagnosed gut disorders. Furthermore, in endometrial tissues of RPL women, higher expression of pro-inflammatory cytokines and Nalp-3 inflammasome has been observed. Aim of this study was to investigate whether an abnormal gut permeability might occur in RPL women and allow passage into systemic circulation of pro-inflammatory molecules able to induce endometrial inflammation. METHODS: 70 women with idiopathic RPL and 30 healthy women were recruited at the Recurrent Pregnancy Loss Outpatient Unit of the Gemelli Hospital of Rome from March 2013 to February 2017. Enrolled women underwent 51Cr-ethylene-diamine-tetraacetic acid absorption test to evaluate intestinal permeability. Sera obtained from enrolled women were analysed for lipopolysaccharide (LPS) by ELISA. Anxiety and depression state were evaluated by administering STAI-Y and Zung-SDS tests, respectively. Of all recruited individuals, 35 women with idiopathic RPL and 20 healthy controls accepted to undergo diagnostic hysteroscopy and endometrial biopsy. Endometrial lysates were investigated for inflammasome Nalp-3 by Western blot analysis, and caspase-1, IL-1ß and IL-18 by ELISA, respectively. RESULTS: Higher prevalence of abnormal intestinal permeability (P < 0.0001), increased circulating levels of LPS (P < 0.05), anxiety (P < 0.05) and depression (P < 0.05) were observed in RLP women compared to controls. Endometrial expression of Nalp-3, caspase-1 and IL-1ß was significantly increased in RPL group (P < 0.0001; P < 0.05 and P < 0.001, respectively). IL-18 endometrial levels were not found to be higher in RPL cases. Statistically significant association between higher intestinal permeability and abnormally increased expression of endometrial Nalp-3, was observed in RPL (P < 0.01). Furthermore, higher LPS serum levels, a bacterial-derived activator of Nalp-3 complex, was shown to be statistically associated to abnormal endometrial expression of Nalp-3 inflammasome (P < 0.01) in RPL women. CONCLUSIONS: In women with RLP, leaky gut might occur and allow passage into circulation of immune triggers, potentially able to elicit endometrial innate immune response and, thus, to contribute to miscarriage pathogenesis. Diagnosis and treatment of intestinal disorders underlying leaky gut might improve endometrial environment and pregnancy outcome.

Fecal microbiota transplantation (FMT) is the transplantation of microbial gut contents from a healthy individual into the gastrointestinal tract of a person with a disease, with a view to increasing the recipient's gut microbial diversity and bacterial richness and restoring microbial homeostasis. FMT has been proven to be a safe and effective treatment for Clostridium difficile infection (CDI) and it is now a recommended treatment for recurrent or refractory infection. FMT is not currently recommended for use outside of CDI due to concerns regarding outcome and safety; however, several case series and randomized controlled trials have described its use in a research environment for a few gastrointestinal conditions related to intestinal dysbiosis including ulcerative colitis (UC), Crohn's disease (CD) and irritable bowel syndrome (IBS). The most successful reports of the clinical efficacy of FMT in gastrointestinal conditions outside of CDI have been in treating UC. We summarize the current literature regarding the use of FMT in UC, including methodology, clinical efficacy and safety concerns, and identify pitfalls and areas for future development. We also describe the available evidence to date on the use of FMT in CD, IBS and other conditions related to intestinal dysbiosi.

OBJECTIVE: Primary small intestinal neoplasms are uncommon tumors that are often small and difficult to identify. The aim of this paper is to describe CT technique and features in detecting and characterizing the tumors of the small bowel. MATERIALS AND METHODS: This paper focuses on radiological characteristics of benign and malignant primary neoplasms of the small bowel at CT, with special reference to multidetector-CT techniques, type and modality of administration of contrast agents (by oral route or CT-enterography and by nasojejunal tube or CT-enteroclysis). This paper will also provide pictures and description of CT findings of benign and malignant primary neoplasms using examples of CT-enterography and CT-enteroclysis. RESULTS: Among CT modalities, CT-enterography has the advantage of defining the real extension of wall lesions, possible transmural extension, the degree of mesenteric involvement and remote metastasis. Other useful modalities for the diagnosis of such lesions like capsule endoscopy and enteroscopy, provide important information but limited to mucosal changes with lower accuracy on extension and bowel wall involvement or submucosal lesions. CONCLUSIONS: Multidetector-CT, performed after distension of the small bowel with oral contrast material and intravenous injection of iodinated contrast material, is a useful method for the diagnosis and staging of small bowel neoplasms.

Iron deficiency anaemia (IDA) is the main extraintestinal manifestation affecting patients with inflammatory bowel disease (IBD). The Health Technology Assessment approach was applied to evaluate the sustainability of intravenous (IV) iron formulations in the Italian hospital setting, with particular focus on ferric carboxymaltose. Data on the epidemiology of IBD and associated IDA, in addition to the efficacy and safety of IV iron formulations currently used in Italy, were retrieved from scientific literature. A hospital-based cost-analysis of the outpatient delivery of IV iron treatments was performed. Organizational and ethical implications were discussed. IDA prevalence in IBD patients varies markedly from 9 to 73%. IV iron preparations were proven to have good efficacy and safety profiles, and ferric carboxymaltose provided a fast correction of haemoglobin and serum ferritin levels in iron-deficient patients. Despite a higher price, ferric carboxymaltose would confer a beneficial effect to the hospital, in terms of reduced cost related to individual patient management and additionally to the patient by reducing the number of infusions and admissions to healthcare facilities. Ethically, the evaluation is appropriate due to its efficacy and compliance. This assessment supports the introduction of ferric carboxymaltose in the Italian outpatient setting.

AIM: To determine the prevalence of psoriasis in an IBD cohort with reference to clinical characteristics and anti-TNFα use. METHODS: Patients with psoriasis and IBD were retrospectively identified from the IBD database at Tallaght Hospital from 2000 to 2015. Pertinent clinical data were obtained from patients notes including anti-TNFα exposure. Prevalence rates of genuine and reactive psoriasis were calculated and compared using Student's T -test. A P values of <0.05 was considered significant. RESULTS: In total, 1384 IBD patients were identified. The overall prevalence rate of IBD and psoriasis was 2.4% ( n = 33), with 1.8% ( n = 25) in the Crohn's disease group and 0.6% ( n = 8) in the ulcerative colitis group. Within the psoriasis group, 24% ( n = 8 of 33) had reactive psoriasis. The prevalence rates of psoriasis in the non-biological and biological cohorts were similar 2.5% (25 of 981) and 2% (8 of 403), respectively. There was no significant association with reactive psoriasis and disease type. There was a trend towards higher rates of reactive psoriasis Adalimumab users, 3.6% (6 of 166) vs. 0.8% (2 of 237), OR = 4.283, P = 0.077, 95% CI 0.854-21.483 in infliximab users. In addition, in our cohort, smoking was not associated with any form of psoriasis in IBD, OR = 1.377, 95% CI 0.061-3.087, P = 0.437. CONCLUSION: In our large study, the prevalence rate of reactive psoriasis was similar to the background rate of psoriasis in the overall IBD cohort (2.0 vs. 2.4%). A 2% prevalence rate represents a common adverse event that clinicians should be aware of.

Malnutrition is a major complication of inflammatory bowel disease (IBD). This mini review is focusing on main determinants of malnutrition in IBD, the most important components of malnutrition, including lean mass loss and sarcopenia, as an emerging problem. Each one of these components needs to be well considered in a correct nutritional evaluation of an IBD patient in order to build a correct multidisciplinary approach. The review is then focusing on possible instrumental and clinical armamentarium for the nutritional evaluation.
ABSTRACT
Gut microbiota is characterized by an inter-individual variability due to genetic and environmental factors. Among the environmental ones, dietary habits play a key role in the modulation of gut microbiota composition. There are main differences between the intestinal microbiota of subjects fed with prevalent Western diet and that of subjects with a diet rich in fibers. Specific changes in the composition of gut microbiota have been demonstrated among subjects according to a different dietary intake. A particular diet may promote the growth of specific bacterial strains, driving hosts to a consequent alteration of fermentative metabolism, with a direct effect on intestinal pH, which can be responsible for the development of a pathogenic flora. Moreover, a high-fat diet can promote the development of a pro-inflammatory gut microbiota, with a consequent increase of intestinal permeability and, consequently, of circulating levels of lipopolysaccharides. In this review, we discuss the direct role of the diet in the composition of gut microbiota and about the possible clinical consequences.
