Colectomy rates in ulcerative colitis: A systematic review and meta-analysis
Surgical management in Ulcerative Colitis (UC) is typically utilised in medically refractory cases and, therefore, it is a useful marker for efficacy of medical management.Vaccinations in patients with inflammatory bowel disease
Treatment of inflammatory bowel disease (IBD) frequently requires administration of immunosuppressive therapies, which increases susceptibility to a number of infectious pathogens. However, many infections can be prevented by correct and appropriate utilization of vaccinations. While several guidelines have been published on vaccination schedules in patients with IBD, vaccination rates remain suboptimal and even lower than those in the general population. This is due to many factors including poor awareness of the importance of vaccines by gastroenterologists and general practitioners as well as potential prejudices of patients regarding the safety and benefits of vaccines.Vaccinations and inflammatory bowel disease – a systematic review
Patients with inflammatory bowel disease(IBD) are at risk of infections, many of which are preventable with vaccinations. We performed a systematic review on various aspects of vaccination in IBD.Quality of life in patients with moderate to severe ulcerative colitis and the impact of treatment: A narrative review
As a chronic inflammatory disease, ulcerative colitis has significant negative impact on the quality of life (QoL) of patients. Since the disease affects many aspects of QoL, comprising multiple domains, treatments that induce and maintain remission can provide benefits beyond hard clinical endpoints. Effective treatment of ulcerative colitis can restore QoL and return it to normal or near normal levels. Biological therapies have shown consistent improvement in the QoL of patients with ulcerative colitis during the induction phase, with benefits that are generally maintained in the long-term.Kidney function monitoring to prevent 5-aminosalicylic acid nephrotoxicity: What the gastroenterologist should know
The kidney function monitoring is recommended in routine practice to detect 5-aminosalicylic acid (5-ASA) related nephrotoxicity, although is not standardized. The optimal monitoring is unknown, especially the best timing and which tests to perform. We summarized why, how, and when to perform the monitoring for patients treated with 5-ASA and provided an overview of the current guidelines on this topic.Inflammatory bowel diseases and the risk of adverse health outcomes: Umbrella review of meta-analyses of observational studies
Accumulating evidence indicates a plausible association between inflammatory bowel diseases and the risk of adverse health outcomes. However, the conclusions are inconsistent. We aimed to perform an umbrella review of meta-analyses to appraise and grade the evidence of the association between inflammatory bowel diseases and the risk of adverse health outcomes.IBDs and the pediatric age: Their peculiarities and the involvement of the microbiota
Inflammatory Bowel Diseases (IBDs) are gastrointestinal disorders characterized by chronic, relapsing inflammation, with growing incidence worldwide over the last decades and distinctive features in the pediatric age. An increasing body of evidence indicates that gut microbiota plays a major role in inflammatory disorders, including IBDs. In this review we will discuss the most recent evidences on dysbiotic changes associated with gut inflammation, as well as environmental and genetic factors contributing to IBD pathogenesis, with a focus on the peculiarities of the pediatric age.Effectiveness of golimumab in ulcerative colitis: A review of the real world evidence
Biologics against tumor necrosis factor (anti-TNF) have dramatically changed the management of moderate-to-severe ulcerative colitis (UC). In pivotal clinical trials, golimumab showed efficacy as induction and maintenance therapy in anti-TNF naïve UC patients. However, confirmatory data on effectiveness in the real world setting are needed.Molecular imaging in gastroenterology: A route for personalized endoscopy
With the rapid expansion and diversification of the repertoire of biological agents utilized in inflammatory bowel diseases and cancer and the increase in oncological patients in gastroenterology, visualization of single receptor or molecular target expression and the subsequent initiation of expression tailored therapy are gaining increasing attention. Through the combination of utilizing fluorescently labeled probes with high specificity towards defined molecular targets and their subsequent detection and visualization with endoscopic devices, molecular imaging is a new emerging field focusing on the receptor expression within the mucosa on a cellular level rather than on macroscopic changes.The contribution of long non-coding RNAs in Inflammatory Bowel Diseases
Inflammatory bowel diseases (IBDs) are multifactorial autoimmune diseases with growing prevalence but the interaction between genetic, environmental and immunologic factors in their development is complex and remains obscure. There is great need to understand their pathogenetic mechanisms and evolve diagnostic and therapeutic tools. Long non-coding RNAs (lncRNAs) are RNA molecules longer than 200 nucleotides that are known to interfere in gene regulation but their roles and functions have not yet been fully understood.Cancer and inflammatory bowel disease in the elderly
Cancer may be a complication of inflammatory bowel disease (IBD) or its treatments. In older Crohn's disease and ulcerative colitis patients, the risk of malignancy is of particular concern. IBD diagnosis at an advanced age is associated with earlier development of colitis-associated colorectal cancer. Thiopurine use in older IBD patients is tied to an increased risk of non-Hodgkin's lymphoma, nonmelanoma skin cancer, and urinary tract cancers. Additionally, older age is accompanied by multimorbidity, an increased risk of malnutrition, and decreased life expectancy, factors that complicate the management of cancer in the elderly.Update on pregnancy and breastfeeding in the era of biologics
Inflammatory bowel diseases are chronic conditions that frequently affect patients during their childbearing years. Considering the characteristics of disease and the medications used to treat it, several issues arise in the care of these patients when they attempt or achieve conception. We review the most current evidence concerning fertility and pregnancy outcomes in patients with inflammatory bowel diseases. With the exception of those women who undergo pelvic surgery, patients with inflammatory bowel diseases have no decreased fertility.New trends in inflammatory bowel disease epidemiology and disease course in Eastern Europe
Trends in current epidemiological data suggest that the incidence of inflammatory bowel diseases is changing. Eastern Europe previously was seen as a low incidence area; however, new data confirm that incidence and prevalence are quickly increasing in some countries, reaching moderate-to-high incidence as reported in Western European countries. The quality of the studies also improved. Recently, data became available on the natural history of the disease from Eastern European countries. Current trends are similar to those reported from Western Europe and North America, including less complicated disease at diagnosis, accelerated use of immunomodulators and decreased need for surgery in Crohn's disease, more cases of proctitis and relatively low colorectal cancer risk in ulcerative colitis.Management of cytomegalovirus infection in inflammatory bowel diseases
Cytomegalovirus is a deoxyribonucleic acid virus that infects a large part of the human population; after primary infection, it develops a latent state and can be reactivated, notably after a decrease in host immune defences. In patients with inflammatory bowel diseases, cytomegalovirus is frequently involved, either as an agent of colitis or through local asymptomatic reactivation. Due to the immune context of inflammatory bowel diseases and to the immunosuppressive therapies that are used to treat them, cytomegalovirus entertains complex relationships with these diseases.Diet and risk of inflammatory bowel disease
A better understanding of the environmental factors leading to inflammatory bowel disease should help to prevent occurrence of the disease and its relapses.Transglutaminases in inflammation and fibrosis of the gastrointestinal tract and the liver
Transglutaminases are a family of eight currently known calcium-dependent enzymes that catalyze the cross-linking or deamidation of proteins. They are involved in important biological processes such as wound healing, tissue repair, fibrogenesis, apoptosis, inflammation and cell-cycle control. Therefore, they play important roles in the pathomechanisms of autoimmune, inflammatory and degenerative diseases, many of which affect the gastrointestinal system. Transglutaminase 2 is prominent, since it is central to the pathogenesis of celiac disease, and modulates inflammation and fibrosis in inflammatory bowel and chronic liver diseases.Questions and answers on the role of faecal calprotectin as a biological marker in inflammatory bowel disease
Faecal calprotectin has been proposed as a non-invasive surrogate marker of intestinal inflammation in inflammatory bowel disease. Close correlation between faecal calprotectin concentration and faecal leukocyte excretion quantified with 111indium has been described. This faecal marker can be detected using simple and cheap techniques. Faecal calprotectin has a good diagnostic precision for separating organic and functional intestinal diseases. However, the specificity for the diagnosis of inflammatory bowel disease is lower than desirable, as several diseases other than inflammatory bowel disease – specially colorectal neoplasia and gastrointestinal infection – can also increase faecal calprotectin.
