The emergence of drug-resistant pathogens has led to a decline in the efficacy of traditional antimicrobial therapy. The rise in resistance has been driven by widespread use, and in some cases misuse, of antibacterial agents in treating a variety of infections. A growing body of research has begun to elucidate the harmful effects of broad-spectrum antibiotic therapy on the beneficial host microbiota. To combat these threats, increasing effort is being directed toward the development of precision antimicrobial therapeutics that target key virulence determinants of specific pathogens while leaving the remainder of the host microbiota undisturbed...

Background and Aims: Medical management of fistulising Crohn's disease (CD) is constrained by the limited number of available therapies. We evaluated the efficacy of vedolizumab, a gut-selective α4β7 integrin antagonist approved for treating moderately to severely active CD, in a subpopulation of patients with fistulising CD who participated in the GEMINI 2 trial (NCT00783692). Methods: Exploratory analyses of data from the GEMINI 2 trial were conducted in 461 responders to 6-week vedolizumab induction therapy who received maintenance placebo (VDZ/PBO, N=153) or vedolizumab (VDZ/VDZ, N=308)...

BACKGROUND: Up to 80% of Crohn`s disease (CD) patients require at least one surgical intervention in their lifetime and up to 70% of these patients develop postoperative endoscopic recurrence within 1 year. The most important predictors of early postoperative recurrence are represented by smoking, prior intestinal surgery, penetrating disease and perianal location. Genetic factors, gut microbiota structure and immunological alterations may be involved in the pathogenesis of postoperative recurrence of CD, although their specific roles have to be determined yet...

Inflammatory bowel diseases (IBD) comprise two disorders of idiopathic chronic intestinal inflammation that affect about three million people worldwide: Crohn's disease and ulcerative colitis. Nowadays, the first-line of treatment for patients with mild to moderate symptoms of IBD comprises corticosteroids, immunosuppressants, antibiotics, and biological agents. Unfortunately, none of these drugs are curative, and their long-term use may cause severe side effects and complications. Almost 40% of IBD patients use alternative therapies to complement the conventional one, and flavonoids are gaining attention for this purpose...

Objective: Fluoroquinolones are not routinely used as the first-line antimicrobial therapy in pediatrics. The American Academy of Pediatrics (AAP) and the United States Food and Drug Administration (FDA) approved fluoroquinolones on certain indications in children. The aim of this study was to evaluate to what extent and how ciprofloxacin is used on approved indication or as off-label. Besides, dose adequacy and treatment duration were assessed. Methods: In a 10-month observational study, all children receiving systemic ciprofloxacin were assessed...

Background: Intra-abdominal abscesses (IAA) are common life threatening complications in patients with Crohn's disease (CD). In addition to interventional drainage and surgical therapy, empirical antibiotic therapy represents a corner stone of treatment but contemporary data on microbial spectra and antimicrobial resistance are scarce. Methods: We recruited 105 patients with CD and IAA from 9 German centers for a prospective registry in order to characterize the microbiological spectrum, resistance profiles, antibiotic therapy and outcome...

One of the best characterized mouse models of the inflammatory bowel diseases (IBD; Crohn's disease, ulcerative colitis) is the CD4+CD45RBhigh T cell transfer model of chronic colitis. Following our relocation to Texas Tech University Health Sciences Center (TTUHSC), we observed a dramatic reduction in the incidence of moderate-to-severe colitis from a 16-year historical average of 90% at Louisiana State University Health Sciences Center (LSUHSC) to <30% at TTUHSC. We hypothesized that differences in the commensal microbiota at the 2 institutions may account for the differences in susceptibility to T cell-induced colitis...

BACKGROUND: Inflammatory bowel diseases (IBD), which include ulcerative colitis and Crohn's disease, cause chronic inflammation of the digestive tract in approximately 1.6 million Americans. A signature of IBD is dysbiosis of the gut microbiota marked by a significant reduction of obligate anaerobes and a sharp increase in facultative anaerobes. Numerous experimental studies have shown that IBD is strongly correlated with a decrease of Faecalibacterium prausnitzii and an increase of Escherichia coli...

The mucous barrier of our digestive tract is the first line of defense against pathogens and damage. Disruptions in this barrier are associated with diseases such as Crohn's disease, colitis, and colon cancer, but mechanistic insights into these processes and diseases are limited. We have previously shown that loss of a conserved O -glycosyltransferase (PGANT4) in Drosophila results in aberrant secretion of components of the peritrophic/mucous membrane in the larval digestive tract. Here, we show that loss of PGANT4 disrupts the mucosal barrier, resulting in epithelial expression of the IL-6-like cytokine Upd3, leading to activation of JAK/STAT signaling, differentiation of cells that form the progenitor cell niche, and abnormal proliferation of progenitor cells...

We report on a 21-year-old woman with a 3-year history of crusts and erosions on her scalp that had appeared after starting treatment with adalimumab due to Crohn's disease. By clinicopathological correlation pityriasis amiantacea with underlying folliculitis decalvans was diagnosed. Topical and systemic antibiotic treatment showed rapid response. The occurrence of pityriasis amiantacea in folliculitis decalvans associated with tumor necrosis factor (TNF)-α inhibitor therapy is remarkable and highlights the ambivalent role of TNF-α in diseases with immunological dysfunctions in combination with infections...

BACKGROUND: Anorectal fistulas (ARFs) are a common, devastating, event in the life of a patient with Crohn's disease. ARFs occur in up to 50% of patients with Crohn's disease. Treatment begins with surgical drainage of the initial abscess, followed by antibiotic therapy, then anti-inflammatory medications. If medical therapy fails to close the fistula tract, surgical intervention is often pursued. Surgery incurs risk of incontinence because of sphincter injury. Increasingly, the role of cell-based therapy is being investigated in ARFs...

BACKGROUND: Fistulas are a common and often debilitating complication of Crohn's disease (CD). Tumor necrosis factor inhibitors and/or seton drainage are effective treatment options. We compared health care utilization and costs for patients with perianal CD who had setons placed before treatment with biologics versus those who did not. METHODS: Patients with CD (≥18 yr) were identified from the Truven Health MarketScan Database by ICD-9 code 555.x (January 1, 2006-March 31, 2015); those with external fistulas were identified by ICD-9 codes 565...

Perianal disease is a common manifestation of Crohn disease (CD) that results in significant morbidity and decreased quality of life. Despite several medical and surgical options, complex perianal CD remains difficult to treat. Before the advent of biologic therapy, antibiotics were the mainstay of medical treatment. Infliximab remains the most well-studied medical therapy for perianal disease. Surgical interventions are limited by the risk of nonhealing wounds and potential incontinence. When treatment options fail, fecal diversion or proctectomy may be necessary...

Fistulas still represent one of the most important complications in patients with Crohn's disease (CD). At least one third of CD patients suffer from fistulas during their disease course and amongst them longstanding remission of complex fistulas occurs only in about one third. So far, fistula pathogenesis is only partially understood. From a histopathological view, a fistula is a tube covered by flat epithelial cells. Current research suggests that the driving force for fistula development is epithelial-to-mesenchymal transition (EMT)...

It is estimated that almost half of patients affected with Crohn disease (CD) experience a dermatologic manifestation of the condition. Metastatic CD (MCD) is a rare dermatologic entity, with as few as 100 cases reported in the literature. As such, MCD presents a clinical dilemma in diagnosis and management. The etiology of MCD is not well defined; however, prevailing theories agree that the underlying mechanism is an immunologic response to gut antigens. Diagnosis requires a high index of suspicion and usually is made by exclusion of other processes...

BACKGROUND: Crohn's disease is an aggressive chronic inflammatory disorder, and despite medical advances no cure exists. There is a great risk of requiring an operative intervention, with evidence of recurrence developing in up to 80-90% of cases. Therefore, we sought to systematically review the current status in the postoperative medical management of Crohn's disease. DATA SOURCES: A systematic literature review of medications administered following respective therapy for Crohn's disease was performed from 1979 through 2016...
