Systemic Oxidative Balance Reflects the Liver Disease Progression Status for Primary Biliary Cholangitis (Pbc): The Narcissus Fountain.

Biological antioxidant potential (BAP) and Reactive Oxygen Metabolites (dROMs) are two tests complementarily assessing systemic oxidative statuses (SOSs) that are never applied in chronic liver disorders (CLDs). We enrolled 41 ursodeoxycholic acid (UDCA)-naïve Primary Biliary Cholangitis (PBC) patients [age: 58.61 ± 11.26 years; females (F): 39], 40 patients with metabolic-dysfunction-associated steatotic livers (age: 54.30 ± 11.21; F: 20), 52 patients with HBV (age: 52.40 ± 8.22; F: 34), 50 patients with (age: 56.44 ± 7.79, F: 29), and 10 controls (age: 52.50 ± 9.64; F: 7). Liver fibrosis and the steatosis severity were determined using transient elastography, and the SOS was balanced using d-ROMs and the BAP test. The gene expressions of superoxide dismutase (SOD1; SOD2) and glutathione peroxidase (GPx1) were evaluated using real-time PCR in advanced fibrosis (AF: F3F4) in patients with PBC. In contrast to other CLDs, in PBC the dROMs and BAP levels were, respectively, directly and inversely correlated with hepatic fibrosis (dROMs, R: 0.883; BAP, R: -0.882) and steatosis (dROMs, R: 0.954; BAP, R: -0931) severity (p < 0.0001 all). Patients with PBC also revealed a progressively increasing trend of d-ROMs (F0-F2 vs. F3: p = 0.0008; F3 vs. F4: p = 0.04) and reduction in BAP levels (F0-F2 vs. F3: p = 0.0007; F3 vs. F4 p = 0.04) according to the worsening of liver fibrosis. In AF-PBC, the SOD1, SOD2, and GPx1 expressions were significantly downregulated in patients presenting SOS imbalance (SOD1, p = 0.02; SOD2, p = 0.03; GPx1, p = 0.02). SOS disequilibrium represents a leitmotiv in patients with PBC, perfectly reflecting their liver disease progression status.

The Burden of Irritable Bowel Syndrome in Medical and Nurse Italian University Student Population: The VANVITELLI-IBS Survey.

BACKGROUND: The increased prevalence of irritable bowel syndrome (IBS) among medical and nursing students is a global challenge. Unfortunately, data on the Italian medical and nurse student population are scarce. Therefore, this study was designed to assess the prevalence of IBS in this setting and to evaluate the demographic, university, Mediterranean diet adherence, and anxiety factors associated with its increased presence. OBJECTIVE: To assess the prevalence of IBS, anxiety levels, and adherence to the Mediterranean diet in medical and nursing university students. METHODS: An anonymous online questionnaire was sent to participants. Several demographic and educational variables were assayed, and the presence of symptoms associated with the definition of IBS (according to Rome IV criteria). In addition, anxiety levels and adherence to the Mediterranean diet were also assessed. RESULTS: Of 161 students, 21.11% met the Rome IV criteria for IBS. Some subgroups, the out-ofcourse students or no scholarship recipients, were found to have a higher percentage of IBS (p < 0.05). Being out-of-course was shown to be associated with an increased and unreported risk of presenting IBS (OR: 8.403, p < 0.001). Levels of anxiety and adherence to the Mediterranean diet were significantly worse in the IBS group (p < 0.01). Adherence to the Mediterranean diet was associated with a reduced risk of presenting IBS in our setting (OR 0.258, p = 0.002). CONCLUSION: Our sample of Italian medical and nursing students recorded a non-negligible percentage of IBS. Therefore, screening and awareness campaigns could be suggested.

Quality of bowel preparation in patients with inflammatory bowel disease undergoing colonoscopy: What factors to consider?

An adequate bowel preparation in patients with inflammatory bowel disease (IBD) is a prerequisite for successful colonoscopy for screening, diagnosis, and surveillance. Several bowel preparation formulations are available, both high- and low-volume based on polyethylene glycol. Generally, low-volume formulations are also based on several compounds such as magnesium citrate preparations with sodium picosulphate, oral sulphate solution, and oral sodium phosphate-based solutions. Targeted studies on the quality of bowel preparation prior to colonoscopy in the IBD population are still required, with current evidence from existing studies being inconclusive. New frontiers are also moving towards the use of alternatives to anterograde ones, using preparations based on retrograde colonic lavage.

A 60-Year-Old Woman with Primary Biliary Cholangitis and Crohn's Ileitis Following the Suspension of Ursodeoxycholic Acid.

BACKGROUND There is a recognized association between inflammatory bowel disease (IBD) and hepatobiliary autoimmune disease, particularly primary sclerosing cholangitis (PSC). There have been fewer reported cases of IBD and primary biliary cholangitis (PBC), which is treated with ursodeoxycholic acid (UDCA). This report presents the case of a 60-year-old woman with PBC who was diagnosed with Crohn's ileitis after suspension of UDCA treatment. CASE REPORT A 66-year-old female patient with PBC was admitted to our department for irrepressible chronic diarrhea and recurrent abdominal pain. PBC was diagnosed on the basis of serological data: chronic (>6 months) increase in alkaline phosphatase (ALP) associated with positivity for specific anti-nuclear antibodies (sp100 and gp210), without requiring a liver biopsy and a magnetic resonance cholangiopancreatography to rule out PSC. Given the intolerance and non-responsiveness according to the Toronto criteria (ALP <1.67 times the normal limit after 2 years) to UDCA at 15 mg/kg/day, an oral monotherapy treatment using obeticholic acid at 5 mg/day was prescribed. The patient complained of abdominal pain and upper gastrointestinal symptoms. The endoscopic/histologic and radiologic examinations supported the diagnosis of Crohn's ileitis. Given the potential benefits to PBC patients of what is described as off-label therapy, budesonide at a dosage of 9 mg/day p.o. was also administered. One month after discharge, an improvement was observed both in the cholestasis indices and in gastrointestinal symptoms. CONCLUSIONS This report presents a case of PBC in which the patient was diagnosed with Crohn's ileitis after cessation of treatment with UDCA, and highlights the importance of recognizing the association between autoimmune hepatobiliary disease and IBD.
