Abstract
Inflammatory bowel diseases, namely ulcerative colitis and Crohn's disease, occur worldwide and affect people of all ages, with a high impact on their quality of life. Sex differences in incidence and prevalence have been reported, and there are also gender-specific issues that physicians should recognize. For women, there are multiple, important concerns regarding issues of body image and sexuality, menstruation, contraception, fertility, pregnancy, breastfeeding and menopause. This practice-based review focuses on the main themes that run through the life of women with inflammatory bowel diseases from puberty to menopause. Gastroenterologists who specialize in inflammatory bowel diseases and other physicians who see female patients with inflammatory bowel diseases should provide support for these problems and offer adequate therapy to ensure that their patients achieve the same overall well-being and health as do women without inflammatory bowel diseases.

Dietary Management in Pediatric Patients with Crohn's Disease.
Scarallo, L, Lionetti, P
Nutrients. 2021;(5)
Abstract
It has been widely endorsed that a multifactorial etiology, including interaction between genetic and environmental factors, can contribute to Crohn's Disease (CD) pathogenesis. More specifically, diet has proven to be able to shape gut microbiota composition and thus is suspected to play a significant role in inflammatory bowel disease (IBD) pathogenesis. Moreover, poor nutritional status and growth retardation, arising from several factors such as reduced dietary intake or nutrient leakage from the gastrointestinal tract, represent the hallmarks of pediatric CD. For these reasons, multiple research lines have recently focused on the utilization of dietary therapies for the management of CD, aiming to target concurrently mucosal inflammation, intestinal dysbiosis and optimization of nutritional status. The forerunner of such interventions is represented by exclusive enteral nutrition (EEN), a robustly supported nutritional therapy; however, it is burdened by monotony and low tolerance in the long term. Novel dietary interventions, such as Crohn's Disease Exclusion Diet or Crohn's Disease treatment with eating, have shown their efficacy in the induction of remission in pediatric patients with CD. The aim of the present narrative review is to provide a synopsis of the available nutritional strategies in the management of pediatric CD and to discuss their application in the dietary management of these patients.

Caio, G, Lungaro, L, Caputo, F, Zoli, E, Giancola, F, Chiarioni, G, De Giorgio, R, Zoli, G
Nutrients. 2021;(5)
Abstract
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) which can affect any part of the whole gastrointestinal tract (from mouth to anus). Malnutrition affects 65-75% of CD patients, and it is now well acknowledged that diet is of paramount importance in the management of the disease. In this review, we would like to highlight the most recent findings in the field of nutrition for the treatment of CD. Our analysis will cover a wide range of topics, from the well-established diets to the new nutritional theories, along with the recent progress in emerging research fields, such as nutrigenomics.

Abstract
Disease-drug-drug interactions (DDDIs) have been identified in some inflammatory diseases in which elevated proinflammatory cytokines can downregulate the expression of cytochrome P450 (CYP) enzymes, potentially increasing systemic exposure to drugs metabolized by CYPs. Following anti-inflammatory treatments, CYP expression may return to normal, resulting in reduced drug exposure and diminished clinical efficacy. Vedolizumab has a well-established positive benefit-risk profile in patients with ulcerative colitis (UC) or Crohn's disease (CD) and has no known systemic immunosuppressive activity. A stepwise assessment was conducted to evaluate the DDDI potential of vedolizumab to impact exposure to drugs metabolized by CYP3A through cytokine modulation. First, a review of published data revealed that patients with UC or CD have elevated cytokine concentrations relative to healthy subjects; however, these concentrations remained below those reported to impact CYP expression. Exposure to drugs metabolized via CYP3A also appeared comparable between patients and healthy subjects. Second, serum samples from patients with UC or CD who received vedolizumab for 52 weeks were analyzed and compared with healthy subjects. Cytokine concentrations and the 4β-hydroxycholesterol-to-cholesterol ratio, an endogenous CYP3A4 biomarker, were comparable between healthy subjects and patients both before and during vedolizumab treatment. Finally, a medical review of postmarketing DDDI cases related to vedolizumab from the past 6 years was conducted and did not show evidence of any true DDDIs. Our study demonstrated the lack of clinically meaningful effects of disease or vedolizumab treatment on the exposure to drugs metabolized via CYP3A through cytokine modulation in patients with UC or CD.

Current Use of EEN in Pre-Operative Optimisation in Crohn's Disease.
Shariff, S, Moran, G, Grimes, C, Cooney, RM
Nutrients. 2021;(12)
Abstract
Despite the increasing array of medications available for the treatment of Crohn's disease and a focus on mucosal healing, approximately 35% of patients with Crohn's disease undergo bowel surgery at some stage. The importance of nutritional optimisation before Crohn's surgery is well-highlighted by surgical, nutritional, and gastroenterological societies with the aim of reducing complications and enhancing recovery. Surgical procedures are frequently undertaken when other treatment options have been unsuccessful, and, thus, patients may have lost weight and/or required steroids, and are therefore at higher risk of post-operative complications. EEN is used extensively in the paediatric population to induce remission, but is not routinely used in the induction of remission of adult Crohn's disease or in pre-operative optimisation. Large prospective studies regarding the role of pre-operative EEN are lacking. In this review, we evaluate the current literature on the use of EEN in pre-operative settings and its impact on patient outcomes.

Let Food Be Thy Medicine-Its Role in Crohn's Disease.
Wellens, J, Vermeire, S, Sabino, J
Nutrients. 2021;(3)
Abstract
The food we eat is thought to play a role in both the increasing incidence as well as the course of Crohn's disease. What to eat and what to avoid is an increasingly important question for both patients and physicians. Restrictive diets are widely adopted by patients and carry the risk of inducing or worsening malnutrition, without any guarantees on anti-inflammatory potential. Nevertheless, exploration of novel therapies to improve long-term management of the disease is desperately needed and the widespread use of exclusive enteral nutrition in the induction of paediatric Crohn's disease makes us wonder if a similar approach would be beneficial in adult patients. This narrative review discusses the current clinical evidence on whole food diets in achieving symptomatic and inflammatory control in Crohn's disease and identifies knowledge gaps with areas for future research.

Abstract
BACKGROUND Treatment with biological agents such as anti-tumor necrosis factors (TNFs) has become standard of care in moderate to severe pediatric inflammatory bowel disease (IBD). However, a significant proportion of patients experience loss of response to anti-TNFs, need treatment escalation, or develop side effects. There is no data in the literature regarding combination of biological agents in pediatric IBD. METHODS At our hospital, which is a tertiary referral center, we have combined the anti-TNF infliximab with either vedolizumab or ustekinumab in patients with severe pediatric IBD. The indications for dual biological therapy were insufficient efficacy of infliximab or vedolizumab monotherapy, or side effects such as psoriasis due to anti-TNFs. RESULTS Eight patients (four boys) aged 14-17.5 years received a combination of infliximab and vedolizumab due to only a partial response to infliximab, four with Crohn's disease (CD) and four with ulcerative colitis (UC). Clinical remission was achieved in four patients (3 UC) and four had a colectomy (3 CD, 1 UC). Five CD patients (3 girls) aged 11-17 years, on maintenance therapy with infliximab, developed psoriasis resistant to topical treatment. A combination of infliximab and ustekinumab resulted in clinical remission of CD without skin symptoms. No serious adverse events occurred in any of the patients on combination therapy. Thirteen publications report on combining biologicals, all in adult IBD. CONCLUSION In pediatric IBD, combining biological agents seems to be safe and beneficial in selected patients. The safety should be addressed in long-term follow-up studies.

ORAL AND ENTERAL NUTRITION THERAPY IN INFLAMMATORY BOWEL DISEASES AMONG THE PEDIATRIC POPULATION: A LITERATURE REVIEW.
Souza, GN, Draghi, PF, Yonamine, GH
Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo. 2020;:e2019032
Abstract
OBJECTIVES To review the literature on oral and enteral nutrition therapy and investigate the evidence of its efficacy as a treatment, as well as in preventing relapses and reducing symptoms of inflammatory bowel diseases in the pediatric population. DATA SOURCE We performed a bibliographic search in the PubMed, Web of Science, and Latin American and Caribbean Health Sciences Literature (Literatura Latino-Americana e do Caribe em Ciências da Saúde - Lilacs) databases, using the keywords "inflammatory bowel disease," "diet," and "diet therapy" in English and Portuguese, with filters for pediatric studies published in the previous five years. DATA SUMMARY We selected 16 articles for this study, nine on exclusive and/or partial enteral nutrition and seven on modified oral diets, such as the specific carbohydrate diet (SCD) and the Crohn's Disease exclusion diet (CDED). The studies found evaluated the anthropometric profile of patients and the inflammatory profile of diseases in children before and after the introduction of each specific nutrition therapy. All interventions presented positive changes in these parameters; however, the results were inconclusive regarding the efficacy of SCD and CDED in the treatment and prevention of relapses. CONCLUSIONS Exclusive enteral nutrition has proven to be effective in inducing remission of Crohn's Disease, and the use of partial enteral nutrition for maintenance treatment has shown promising results. Other modified oral diets are inconclusive concerning their effectiveness, requiring further randomized controlled clinical trials.

A modern multidisciplinary approach to the treatment of enterocutaneous fistulas in Crohn's disease patients.
Papa, A, Lopetuso, LR, Minordi, LM, Di Veronica, A, Neri, M, Rapaccini, G, Gasbarrini, A, Papa, V
Expert review of gastroenterology & hepatology. 2020;(9):857-865
Abstract
INTRODUCTION Enterocutaneous fistulas (ECFs) is a manifestation of penetrating Crohn's disease (CD) that is challenging to treat and has considerable morbidity and mortality rates. AREAS COVERED This review aims to explore the practical and updated principles for the optimal treatment of ECFs in CD patients. EXPERT OPINION Optimal ECF management requires a multidisciplinary approach. Treatment first includes fluid resuscitation and electrolyte rebalancing with control of sepsis by means of antibiotics and, when indicated, drainage of infected collections. Subsequent therapeutic steps include nutritional support, control of the fistula output and treatment of peristomal skin. Anti-TNF-α therapy seems to have limited utility only after sepsis is resolved and intestinal stenosis excluded. However, ECFs heal in only approximately one-third of cases without surgical intervention. Thus, correct surgical timing combined with adequate nutritional support, sepsis resolution and skin care is considered the appropriate preoperative setting.

The fate of myofibroblasts during the development of fibrosis in Crohn's disease.
Li, C, Kuemmerle, JF
Journal of digestive diseases. 2020;(6):326-331
Abstract
Intestinal fibrosis is a devastating complication in patients with inflammatory bowel disease. Its characteristics include the loss of regular peristalsis and nutrition absorption, excessive deposition of extracellular matrix (ECM) components, thickness of intestinal lumen due to the formation of strictures and of scar tissue. As a major cell type involved in fibrogenesis, the myofibroblasts have already been shown to have a plastic and heterogeneous function in producing abundant collagen, fibronectin and connective tissue growth factor. The primary sources of ECM-producing and vimentin-positive myofibroblasts come from different precursor cells, including bone marrow-derived mesenchymal cells, fibrocytes, pericytes, epithelial to mesenchymal transition and endothelial to mesenchymal transition. Recent immunological research findings suggest that numerous cytokines and chemokines made from macrophages, in addition to T cells and other myeloid cell types, are also important drivers of myofibroblast differentiation and hence of the activation of myofibroblast-mediated transforming growth factor and collagen production. In this review we discuss the origins, roles and cell signaling of myofibroblasts during the development of fibrosis in different organs, particularly in Crohn's disease. Finally, we suggest that the epigenetic and immunological regulation of myofibroblast differentiation may provide a novel antifibrotic strategy in the near future.
