Filter by:Oral polio and rotavirus vaccines are significantly less effective in children living in the developing world. Tropical enteropathy, which is associated with intestinal inflammation, decreased absorption and increased permeability, may contribute substantially to oral vaccine failure in developing country settings. Other possible causes of oral vaccine underperformance include malnutrition, interference with maternal or breast milk antibodies, changes in gut microbiota, and genetic susceptibility.The primary Objective of this study is to determine whether decreased vaccine responsiveness to oral poliovirus or rotavirus vaccines is associated with the presence of tropical enteropathy.
The investigators examined the outcome of patients with severe Enterohaemorrhagic E. Coli (EHEC) O104:H4 infection suffering from bloody diarrhoea that were at risk to develop hemolytic uremic syndrome and underwent repetitive whole bowl lavage during hospitalization.
Inflammatory bowel disease (IBD) is a chronic, debilitating, relapsing inflammatory disorder affecting the gastrointestinal tract which does not have a medical cure. IBD consists of 2 different forms: Crohn's Disease (CD) and Ulcerative Colitis (UC). In the last 2 decades, Gut Microbial Transplantation (GMT), also known as fecal transplantation, has been used as a treatment option for Clostridium difficile colitis and UC. The literature supports strong evidence for the plausibility of using GMT for patients with IBD associated colitis, especially for patients with UC. This research will be conducted in the Helen DeVos Children's Hospital (HDVCH) Pediatric gastrointestinal outpatient clinic. A pilot study of ten patients will be conducted to evaluate if GMT improves clinical symptoms in patients with IBD. Patients with IBD colitis (UC and CD with colonic involvement only) will be approached for GMT as a treatment option for their disease. Each subject will undergo 5 sessions (1 session/day, and not necessarily on consecutive days) of GMT within a period of 10 days. Post treatment evaluation will be done at their regularly scheduled clinic follow up. Healthy donors >18 years of age will be chosen by the family, inclusive of immediate family members and friends. Donors will be required to complete a screening questionnaire, provide medical history, and undergo blood and stool tests.
Significance: Biopsy of potentially benign pseudopolyps and the surrounding mucosa adds expense and prolongs the time of endoscopic procedures. Use of endoscopic technologies could decrease the need and expense of endoscopic biopsy for these lesions. Hypothesis: Pseudopolyps will have a distinctive pattern with the specialized imaging techniques of high definition imaging, narrow band imaging, and endoscopic dye-spraying techniques using indigo carmine which will predict diagnosis without biopsy. 100 patients with inflammatory bowel disease will be enrolled in the study. Following a standard bowel preparation, each patient will be evaluated using standard endoscopic equipment. All patients will receive a standard bowel preparation (sodium phosphate, PEG-3350, or magnesium citrate based preparations). All colonoscopic evaluations will be performed for indications unrelated to the present study, including evaluation of response to medical treatment, routine surveillance exams for dysplasia, diarrhea, or rectal bleeding. Polypoid lesions will be examined using four consecutive methods: (a) high definition white light, (b) narrow band imaging, (c) chromoendoscopy (high definition white light with indigo carmine dye-spraying), and (d) histologic examination following biopsy. The flat mucosa surrounding the polypoid lesions will also be examined using theses four techniques in an effort to identify dysplastic tissue associated with these polypoid growths. High definition white light is the standard imaging modality used for colonoscopy. Narrow band imaging (blue wavelength of light) is also used routinely and is available on all current generation colonoscopes with the press of a button. Our division routinely uses chromoendoscopy as part of surveillance for dysplasia in patients with inflammatory bowel disease. Dye spraying catheters or flushing will be utilized for dye application to mucosa. The dye used will be indigo carmine. Directed biopsy specimens will then be performed using a multibite forceps for targeted biopsies. Routine biopsies will be performed as clinically indicated. Pathology slides will be reviewed by the gastrointestinal pathologists at the University of Miami. The gastroenterologist's interpretation based on each of the three successive endoscopic methods will then be compared to the histologic evaluation with each individual lesion serving as its own control.
In this study, it is hypothesized that helminth infections modulate immune responses against HIV-1 infection resulting into increased HIV-1 multiplication, faster progression to AIDS and increased episodes of AIDS-related opportunistic infections. Furthermore, the effect of helminth infections on progression of HIV-1 infection is dependent on helminth infection intensity, host background immunity, nutritional status, demographic factors and socio-economic status. Also, treatment of helminth infections using praziquantel and albendazole among HIV-1 infected individuals will lead to reduction in HIV-1 viral loads, improvement of CD4+ counts, CD4+/CD8+ ratio and Hb levels, improved weight gain and reduction of episodes of HIV-1 related opportunistic infections. In addition, HIV-1 infection is associated with poor anthelminthic treatment outcome as compared to non-HIV infected individuals
The purpose of the study is to test an online behavioral intervention to improve medication adherence in children diagnosed with Inflammatory Bowel Disease. Interested families will be monitored for four weeks to determine how frequently their child's IBD medication is taken. Patient's taking less than 90% of medications will be randomized to one of two intervention conditions to complete intervention sessions online. The study consists of 4 online intervention sessions with topics differing by condition and 5 online assessments to complete quality of life questionnaires over a 14 month time frame.
The objective is to assess the efficacy of Hepatitis B Virus vaccination in a population of IBD patients treated with immunosuppressive medications.
The purpose of this study is to investigate the proportion of use of complementary and alternative medicine (CAM) in patients with inflammatory bowel disease (IBD). In addition, the reason for, and satisfaction with use of CAM.
Inflammatory bowel disease (IBD) encompasses two major forms of chronic intestinal disorders, Crohn's disease and ulcerative colitis (UC). Diagnosis is based on several macroscopic and histologic features including patterns of inflammation, crypt abscesses and granulomas. Confocal laser endomicroscopy (CLE) is rapidly emerging as a valuable tool for gastrointestinal endoscopic imaging, enabling the endoscopist to obtain an "optical biopsy" of the gastrointestinal mucosa during the endoscopic procedure. The main objective of this study is to determine endoscopic and endomicroscopic features of mucosal healing in patients with IBD.
Examine whether daily oral ingestion of a immunomodulatory mushroom extract (AndoSanTM) in patients with ulcerative colitis (UC) and Crohn's disease (CD), experience clinical, biochemical and genetical improvement in their disease. A prospective randomised study comparing the mushroom extract with placebo.
