Recurrent infection (CDI) is a major health threat with significant mortality and financial costs. Fecal Microbiota Transplantation (FMT) is an effective therapy, however the mechanisms by which it acts, particularly on the host, are poorly understood. Here we enrolled a prospective cohort of human patients with recurrent CDI (n=16) undergoing FMT therapy.
View Article and Find Full Text PDFObjectives: In the US, Clostridioides difficile (C. difficile) infection (CDI) is the 8th leading cause of hospital readmission and 7th for mortality among all gastrointestinal (GI) disorders. Here, we investigated GI dysfunction post-CDI in humans and mice post-acute infection.
View Article and Find Full Text PDFObjectives: Clostridioides difficile infection (CDI) is characterized by neutrophilia in blood, with a high leukocyte count accompanying severe infection. In this study, we characterized peripheral blood neutrophil activation and maturity in CDI by (i) developing a method to phenotype stored neutrophils for disease-related developmental alterations and (ii) assessing neutrophil-associated biomarkers.
Methods: We stored fixed leukocytes from blood collected within 24 h of diagnosis from a cohort of hospitalized patients with acute CDI.
Introduction: is the leading cause of healthcare-associated infections in the USA, with an estimated 1 billion dollars in excess cost to the healthcare system annually. infection (CDI) has high recurrence rate, up to 25% after first episode and up to 60% for succeeding episodes. Preliminary in vitro and in vivo studies indicate that alanyl-glutamine (AQ) may be beneficial in treating CDI by its effect on restoring intestinal integrity in the epithelial barrier, ameliorating inflammation and decreasing relapse.

Patients with concomitant PSC-IBD are at higher risk for IBD-related complications including dysplasia and malignancy, however the typical clinical IBD course is less severe. The aim of this study was to identify the prevalence of biologic use and therapeutic drug monitoring (TDM) in a cohort of PSC-IBD patients.

Given the length and distinctive embryonic origins of the proximal and distal colon, we investigated whether inherent regional differences of immune cell composition could introduce confounders when sampling different disease stages, or pre/post drug administration. Here, we capitalise on novel mass cytometry technology to perform deep immunophenotyping of distinct healthy colonic segments, using the limited numbers of biopsies that can be harvested from patients.

The present study aimed to determine the prevalence and patient-specific characteristics associated with polypharmacy in an ulcerative colitis (UC) population and to assess the impact of polypharmacy on disease outcomes.
Methods: A retrospective chart review of patients with UC who visited a tertiary medical center outpatient clinic between 2006 and 2011 was performed.
Background: Patients with ulcerative colitis (UC) may be exposed to opioids over their disease duration. The use of such medications carries significant risk, including intestinal dysmotility and potential for addiction. However, the rates of narcotic use and misuse in patients with UC have not been studied extensively.

However, in 12% of patients treated with FMT, CDI recurs within one month. Zinc deficiency predicts increased diarrheal frequency in malnourished children, but little is known about its association with FMT outcome.
View Article and Find Full Text PDFBackground: Nonadherence to medications is common with patients with inflammatory bowel disease (IBD). The aim of this study was to assess adherence to biologic medications prescribed for IBD and to identify risk factors for biologic nonadherence.
Methods: This was a single center retrospective cohort study investigating IBD patient adherence to biologic therapies over a 2-year period from September 2014 to September 2016.
Introduction: Type-1 hepatorenal syndrome (HRS-1) portends a poor prognosis in patients with cirrhosis. Currently available medical therapies are largely ineffective, save for liver transplantation. We aimed to determine if pentoxifylline (PTX) therapy in addition to the standard of care of volume expansion with albumin and vasoconstriction with midodrine and octreotide (AMO) is safe and efficacious compared to AMO in HRS-1 treatment.

Drug-induced liver injury is a rare but clinically important diagnosis. Vedolizumab is an α4β7 integrin inhibitor recently approved for use in patients with moderate-to-severe inflammatory bowel disease. Cases of hepatoxicity due to vedolizumab in the pre-marketing stage were rare, and all cases resolved upon drug withdrawal.

The aim of this study was to assess whether treatment with anti-tumor necrosis factor-α (TNF-α) therapy was associated with a decreased risk of thromboembolism.
Methods: We identified IBD patients hospitalized between July 2002 and July 2011 at our institution.
Background: We performed a systematic review to evaluate the efficacy and safety of vedolizumab for induction and maintenance of remission in ulcerative colitis.
Methods: A literature search to June 2014 identified all applicable randomized trials. Outcome measures were clinical and endoscopic remission, clinical and endoscopic response, quality of life, and adverse events.
Background: The rate of narcotic misuse in the inflammatory bowel disease population is not well studied. The primary aim of this study was to determine in Crohn's disease (CD) whether a concurrent functional gastrointestinal disorder (FGID) was associated with increased rates of chronic narcotic use. Second, we aimed to identify potential risk factors for narcotic misuse.

Background: Cellular adhesion molecules play an important role in the pathogenesis of ulcerative colitis, making selective blockade of these molecules a promising therapeutic strategy. Vedolizumab, a recombinant humanized IgG1 monoclonal antibody, inhibits adhesion and migration of leukocytes into the gastrointestinal tract by binding the alpha4beta7 integrin. Animal studies have suggested that vedolizumab may be a useful therapy for ulcerative colitis.

The advent of anti-tumor necrosis factor (TNF)-α therapy has been a major advance in the medical management of Crohn's disease (CD). However, a significant proportion of patients with CD do not respond adequately to treatment with these agents. Primary and secondary nonresponse to anti-TNFα therapy represents a common clinical challenge, and highlights the need for the development of additional medication options for CD.

Dexlansoprazole modified release (MR; Dexilant™), the R-enantiomer of lansoprazole, was approved in the USA in 2009 for the management of erosive esophagitis and nonerosive reflux disease. Dexlansoprazole MR has a unique dual delayed-release delivery system that was designed to address unmet needs that may accompany the use of single-release proton pump inhibitors (PPIs), specifically, their short plasma half-life and requirement for meal-associated dosing. The delivery technology of dexlansoprazole MR is designed to release the drug in two separate pH-dependent phases, the first in the proximal duodenum and the second in the more distal small intestine.

Infliximab is arguably the first major advance in therapy for inflammatory bowel disease in more than a quarter of a century. Although it is important to distinguish efficacy from effectiveness, the data from clinical practice mirror those from randomized controlled trials. Infliximab has proven efficacious for luminal manifestations of Crohn's disease (CD) regardless of location.
