The role of new inflammatory indices in the prediction of endoscopic and histological activity in inflammatory bowel disease patients.

Background And Aim: Inflammatory indices are promising indicators that can be used to evaluate inflammation in inflammatory bowel diseases (IBDs). The present study aimed to investigate the test accuracy of several inflammatory indices to identify endoscopic, and histological activity in a cohort of IBD patients.

Study: All IBD patients who underwent colonoscopy and blood examination (within 4 weeks and without therapeutic change) were included.

IBD Patients with Primary or Secondary Nonresponse to Ustekinumab Benefit from Dose Escalation or Reinduction.

Ustekinumab is a monoclonal antibody approved for the treatment of IBD. This drug has a well-established efficacy; however, patients may not respond or lose response. The availability of other biological therapies prompts the need for comparative data between different agents to suggest first- or second-line strategies.

Vaccine Acceptance in Patients with Inflammatory Bowel Disease: Lessons Learned from the COVID-19 Pandemic.

Background: Immunomodulating therapies, which are commonly used in patients with Crohn's disease (CD) and ulcerative colitis (UC), have been linked to an increased risk of contracting opportunistic infectious diseases, the majority of which are preventable through vaccination. Nonetheless, vaccination rates in these patients are suboptimal, and frequently lower than in the general population. The COVID-19 immunization schedule provided a new scenario for investigating vaccine acceptance in patients with inflammatory bowel disease (IBD), with uncertainty and concerns emerging and the number of subjects receiving the third and fourth doses of the vaccine gradually decreasing.

Immunoglobulin G4-Related Disease of the Intestine: A Clinicopathological Entity to Be Considered.

: Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized immune-mediated, systemic condition of unknown etiology, associated with fibroinflammatory lesions. Diagnosis is set in the presence of IgG4-positive plasma cell infiltration of the involved tissue and elevated serum IgG4 levels. However, approximately 30% of patients have normal serum IgG4 levels.

COVID-19 and Gastrointestinal Tract: From Pathophysiology to Clinical Manifestations.

: Since its first report in Wuhan, China, in December 2019, COVID-19 has become a pandemic, affecting millions of people worldwide. Although the virus primarily affects the respiratory tract, gastrointestinal symptoms are also common. The aim of this narrative review is to provide an overview of the pathophysiology and clinical manifestations of gastrointestinal COVID-19.

Adsorptive cytapheresis in ulcerative colitis: A non-pharmacological therapeutic approach revisited.

Adsorptive cytapheresis proves effective in a proportion of patients affected by ulcerative colitis. Relatively high cost and the need for apheresis facilities, prevented the widespread use of this therapeutic approach. More so following the introduction of anti-TNFα biosimilars which proved both effective and inexpensive.

Low Vitamin K and Vitamin D Dietary Intake in Patients with Inflammatory Bowel Diseases.

The inadequate dietary intake of Vitamin D and Vitamin K is an easily reversible factor favoring IBD-associated bone loss, but data on Vitamin K are lacking. A 28-item quantitative food frequency questionnaire was administered to 193 IBD patients (89 Crohn's disease and 104 ulcerative colitis), and 199 controls. Patients' demographics, clinical and laboratory findings were analyzed in relation to recommended daily allowances.

Effectiveness of Vitamin D Supplementation on Disease Course in Inflammatory Bowel Disease Patients: Systematic Review With Meta-Analysis.

Background: The vitamin D role in bone metabolism is well known; however, recent evidence suggests the impact of vitamin D in immune modulation and its implications in immune-mediated diseases, including inflammatory bowel disease (IBD).

Method: We performed a systematic review with meta-analysis by a specific protocol (PROSPERO: CRD42022311184; March 2022, https://www.crd.

Systematic review and meta-analysis: the advantage of endoscopic Mayo score 0 over 1 in patients with ulcerative colitis.

Background: Mucosal healing (MH) evaluated by endoscopy is a novel target of therapy in UC as it is associated with improved long-term outcomes. It is defined based on the Mayo endoscopic score (MES), but it is still to define whether a value of MES 0 or 1 should be the target. The purpose of this paper is to present the results of a systematic review with meta-analysis which compares long-term outcomes of patients in steroid-free clinical remission with MES 0 with those with MES 1.

Non-steroidal anti-inflammatory drugs and acetylsalicylic acid increase the risk of complications of diverticular disease: a meta-analysis of case-control and cohort studies.

Background: The role of non-steroidal anti-inflammatory drugs (NSAIDs) and acetylsalicylic acid in the occurrence of diverticular bleeding (DB), complicated diverticulitis (CD), and acute diverticulitis (AD) is not yet defined.

Aim: Update a systematic review and meta-analyses of case-control and cohort studies to evaluate the association between NSAIDs or acetylsalicylic acid with DB, CD, or AD.

Methods: The study included were identified through MEDLINE, Scopus, Web of Science, and Cochrane Library databases.

Vitamin D in Inflammatory Bowel Diseases. Mechanisms of Action and Therapeutic Implications.

(1) Background: Vitamin D is an immunoregulatory factor influencing intestinal homeostasis. Recent evidence supports a central role of this micronutrient in the course of Inflammatory Bowel Diseases (IBD). This narrative review aims to provide a general overview of the possible biological mechanisms of action of vitamin D and its therapeutic implications in IBD.

Risk of colonoscopic post-polypectomy bleeding in patients on single antiplatelet therapy: systematic review with meta-analysis.

Background: It was not yet fully established whether the use of antiplatelet agents (APAs) is associated with an increased risk of colorectal post-polypectomy bleeding (PPB). Temporarily, discontinuation of APAs could reduce the risk of PPB, but at the same time, it could increase the risk of cardiovascular disease recurrence. This study aimed to assess the PPB risk in patients using APAs compared to patients without APAs or anticoagulant therapy who had undergone colonoscopy with polypectomy.

Fecal Lactoferrin and Other Putative Fecal Biomarkers in Crohn's Disease: Do They Still Have a Potential Clinical Role?

Introduction: The need for noninvasive markers of disease activity is mandatory in the assessment of Crohn's disease (CD). The most widely fecal biomarker in CD, despite several limits, is fecal calprotectin. This review aims to elucidate the role, if any, of all other fecal biomarkers, as alternative tools for assessing clinical and endoscopic disease activity, and predict capsule endoscopy findings, response to therapy, disease relapse, and postoperative recurrence.

Are Volatile Organic Compounds Accurate Markers in the Assessment of Colorectal Cancer and Inflammatory Bowel Diseases? A Review.

Colorectal cancer (CRC) is one of the leading causes of cancer-related death in the Western world. Early detection decreases incidence and mortality. Screening programs based on fecal occult blood testing help identify patients requiring endoscopic examination, but accuracy is far from optimal.

Serum transglutaminase antibodies do not always detect the persistent villous atrophy in patients with celiac disease on a gluten-free diet.

Background And Aim: Serum transglutaminase antibodies (tTGs) are used for celiac disease screening and to monitor celiac disease patients on a gluten-free diet (GFD). The need for histology of duodenal biopsies to assess mucosal healing after a GFD is still a matter of debate. We evaluated whether tTGs are adequate to detect the persistence of histological lesions of duodenal mucosa in celiac patients after a GFD.

Posterior Reversible Encephalopathy Syndrome After Azathioprine Administration in Severe Ulcerative Colitis.

Posterior reversible encephalopathy syndrome is a rare syndrome characterized by brain edema and neurological symptoms, often resulting from several drugs. Treatment is based on discontinuation, and diagnosis is thus essential. Only 13 cases of posterior reversible encephalopathy syndrome have been reported in inflammatory bowel diseases, and we present the first after azathioprine in adults.

Association of Colonic Diverticula with Colorectal Adenomas and Cancer.

Conflicting evidence is reported regarding any association between colonic diverticula with colorectal adenomas or cancer. The present study aimed to evaluate, in a cohort of Caucasian patients, the association between colonic diverticula and colorectal polyps and cancer. All consecutive patients undergoing colonoscopy at our institution were included in the study.

The Usefulness of Serum Vitamin D Levels in the Assessment of IBD Activity and Response to Biologics.

The main role of vitamin D is calcium homeostasis and bone metabolism, although its activity as an immuno-modulator and its anti-inflammatory effect is well-known. Low blood vitamin D levels are common among patients with inflammatory bowel disease (IBD). Whether low vitamin D levels could affect the disease activity or it is an effect of a worse condition of the disease is still unclear.

Sleep disorders related to nutrition and digestive diseases: a neglected clinical condition.

Sleep disturbances often result from inappropriate lifestyles, incorrect dietary habits, and/or digestive diseases. This clinical condition, however, has not been sufficiently explored in this area. Several studies have linked the circadian timing system to the physiology of metabolism control mechanisms, energy balance regulation, and nutrition.

Dietary Factors Modulating Colorectal Carcinogenesis.

The development of colorectal cancer, responsible for 9% of cancer-related deaths, is favored by a combination of genetic and environmental factors. The modification of diet and lifestyle may modify the risk of colorectal cancer (CRC) and prevent neoplasia in up to 50% of cases. The Western diet, characterized by a high intake of fat, red meat and processed meat has emerged as an important contributor.

Early hydrogen excretion peaks during breath tests. Small intestinal bacterial overgrowth or accelerated transit?

Background: Small intestinal bacterial overgrowth (SIBO) has been reported with varying prevalence, depending upon the criteria used for diagnosis. Lactulose and glucose breath tests are the most used in clinical settings. Early rises of hydrogen excretion during a lactose breath test suggest SIBO, but the finding could result from accelerated mouth-to-caecum transit time.

Role of Ulcerative Colitis Endoscopic Index of Severity (UCEIS) versus Mayo Endoscopic Subscore (MES) in Predicting Patients' Response to Biological Therapy and the Need for Colectomy.

Background: The main goal in the treatment of ulcerative colitis (UC) is to achieve mucosal healing. Despite being unvalidated, the most widely used scoring system is the Mayo endoscopic subscore (MES). However, the recently established and validated Ulcerative Colitis Endoscopic Index of Severity (UCEIS) represents an interesting alternative method in assessing endoscopic disease activity.

Is fecal calprotectin an accurate marker in the management of Crohn's disease?

Although lacking validated cutoff values, fecal calprotectin (FC), besides C-reactive protein, is considered the standard test for assessing disease activity in Crohn's disease (CD). The aim of the present review is to provide a general overview of the literature addressing the role of FC in the clinical and endoscopic assessment of disease activity in CD, seeking correlations with capsule endoscopy, response to therapy, prediction of relapse, and postoperative recurrence. A systematic search of the literature up to September 2019 was performed using Medline, Embase, and the Cochrane Library.

Metabolic Alterations in Celiac Disease Occurring after Following a Gluten-Free Diet.

Background And Aim: Many investigations have demonstrated that changes in body weight are frequent in patients with coeliac disease (CD) after a gluten-free diet (GFD); conversely data on the metabolic syndrome (MS) and hepatic steatosis (HS) are still rare. The aim is to evaluate the prevalence of MS and HS in patients with CD, before and after a GFD.

Methods: One hundred eighty-five coeliac adult patients were enrolled in the study.
