Filter by:This is a randomized, double blind trial of combination therapy (Cimzia plus Azathioprine) versus mono therapy (Cimzia alone) and the improvement in mean SES-CD (Simple Endoscopic Scoring in Crohn's Disease) score. It is a trial where the investigators are administering biological therapy by itself and biological therapy plus an immunosuppressive medicine in combination to see which form of therapy has a better effect on healing ulcerations in the small intestine and colon that are due to a flare up of Crohn's disease.
The inflammatory bowel diseases (IBD), ulcerative colitis (UC) and Crohn's disease (CD) are chronic conditions affecting approximately 1.4 million Americans. The burden of Clostridium difficile infection (CDI), a frequent cause of infectious diarrhea is mediated by toxins A and B and is increasing faster in IBD patients, than the general population. Clinically, CDI in patients with IBD leads to a range of clinical syndromes from symptomless carriage, to severe life threatening colitis, colectomy and death. This pilot study will look at the relationship between IBD and this variable host immune response. Clostridium difficile colonization (asymptomatic carrier state) is lower in the IBD population than in the general population. In the general population, high antitoxin titers have been linked with colonization and low antitoxin titers with recurrent disease. The investigators hypothesize that patients with IBD will have a lower Clostridium difficile colonization and will have lower antibody titers than the control group. Additionally those with lower titers will have an increased risk of developing CDI. In Aim 1 the investigators will determine Clostridium colonization in IBD subjects by stool study (including CD, UC and UC patients after IPAA) compared to non-IBD subjects (controls). In Aim 2 the investigators will compare antitoxin titers in these IBD subjects compared to controls. In Aim 3 the investigators will follow these subjects for 12 months and calculate the incidence of CDI in patients with IBD compared to controls and associations with anti-toxin titers.
The investigators will be looking at the efficacy of the use of once daily use of low dose naltrexone (4.5mg) in subjects with symptomatic inflammatory bowel disease.
The purpose of this study is to evaluate the safety profile and to obtain an indication as to the therapeutic effect of QBECO induction treatment on clinical improvement in moderate to severe Crohn's Disease.
The goal of the present study is to evaluate the best regimen for infliximab monotherapy, and to evaluate if limited combination therapy with IFX and an Immunomodulator for the first 6 months of therapy, in prior Immunomodulator failures, is superior to monotherapy with Immunomodulator cessation from the second infusion, in preventing loss of remission to IFX.
The purpose of the OTIS Autoimmune Diseases in Pregnancy Study is to monitor planned and unplanned pregnancies exposed to certain medications, to evaluate the possible teratogenic effect of these medications and to follow live born infants for five years after birth. With respect to fetal outcome, it is important to evaluate the spectrum of outcomes that may be relevant to a medication exposure during pregnancy, and these include both easily recognizable defects which are visible at birth, as well as more subtle or delayed defects that may not be readily identifiable without special expertise and observation beyond the newborn period.
Hypothesis This study is designed as an integral part of the development of a new CE score for Crohn's disease. The SB (small bowel) CD (Crohn's Disease)Niv score (CECDAI) is an established and validated CD score for SB involvement. In order to expand this score to the colon, this study will aim to develop the colonic score and later on will be combined with the already established SB score in order to achieve a full CE gut score for Crohn's disease Proposed Design This is a retrospective study in which up to 30 videos of colon Crohn's disease subjects who have undergone the Colon 2 CE procedure will be evaluated. These cases will have evidence of large and / or small bowel Crohn's disease The chosen videos will be marked for CD lesions by the site The de-identified marked videos will be scored by 4 independent experienced endoscopists, blinded to the results of the standard workup procedures, according to the colonic and CECDAIic new scores
Increased Intestinal Permeability is detectable in clinically active Crohn's disease, in stable Crohn's disease and is predictive of clinical relapse. Maintenance of the epithelial barrier integrity is therefore essential for intestinal homeostasis. Vitamin D may have a critical role in improving barrier function.
The purpose of this study is to develop a predictive model that will allow optimized dosing of infliximab for individual patients
There is growing evidence that Crohn's disease may be caused by replication of bacteria, perhaps particularly E. coli, within macrophages (a specialized sort of white blood cell). Laboratory studies show that a combination of antibiotics that can penetrate macrophages (such as ciprofloxacin and doxycycline) together with the anti-malarial drug hydroxychloroquine (which makes the contents of macrophage vesicles more alkaline and helps them to kill intracellular bacteria) is particularly effective at killing the E. coli within macrophages.
