Active clinical trials for "Inflammation"

This study aims to observe inflammatory biomarkers and their trend over the history of the disease in patients suffering from MPN Ph negative; it also wants to identify any correlations between the aforementioned biomarkers and disease outcomes, considering first of all the occurrence of thrombo-haemorrhagic events and the evolution in the accelerated / blast phase of the disease, shedding light on new tools that can potentially guarantee a prompt and better risk stratification

As a consequence of chronic relapsing inflammation in Crohn's disease (CD), progressive bowel damage and scarring occurs in affected regions of intestine. This damage often leads to narrowing, or stricturing of the bowel lumen, and even complete bowel obstruction. Stricturing CD is thought to be a major contributor to penetrating complications including abscesses and fistulae. Depending on the severity and clinical significance of fixed strictures, treatment options include either endoscopic balloon dilatation (EBD), or surgery with either resection or stricturoplasty recommended on a case-by-case basis. EBD has been shown to be a safe alternative to surgery in management of CD strictures. While the short- and medium-term clinical outcomes of EBD have been well described, less well studied is the impact of relieving Crohn's strictures on the inflammatory load proximal to the stricture. The restricted flow of fecal contents through a stricture creates a region of relative stasis in the bowel loops immediately proximal to the stricture, appreciated at times by pre-stenotic dilatation on cross-sectional imaging. This stasis fosters localized bacterial overgrowth and worsening dysbiosis in these bowel loops. The investigators hypothesize that improvement of fecal flow by way of successful balloon dilatation of a CD stricture, could independently reduce the inflammatory burden, not only in the stenotic segment but also in the proximal loop of bowel.

This is a laboratory-based study and it aims to evaluate the expression of inflammasomes in healthy gingiva and in the presence of peri-implantitis and periodontitis

The study will show the influence of inflammatory bowel disease on the risk of development of atherosclerosis

The purpose of this study is to investigate white blood cells from volunteering donors to support the development of engineered regulatory T cell therapies.

This protocol is a natural history study designed to evaluate subjects (and some family members) with suspected or identified genetic diseases of allergic inflammation or Immune Dysregulation. Patients determined by clinical history and outside evaluations to be of interest will be consented and enrolled into this study. Blood specimens, stored blood products and derivatives, saliva, hair, fingernail clippings, cord blood, umbilical cord, bone marrow, tissue biopsies and/or buccal swabs from such patients and/or their family members will be obtained for research studies related to understanding genetic and immunopathogenic bases of these diseases. Outside medical records may be obtained, and patient evaluations may be performed to correlate to research laboratory testing results.

Analysis of humoral antibody and cytokine kinetics after vaccination with either BNT162b2 or ChAdOx1 nCoV-19 vaccine and factors influencing the vaccine immunogenicity

This protocol is being established to cover the evaluation of patients with inflammatory and/or infectious diseases which are not covered under previously existing protocols. The purpose of such a protocol is that frequently patients are referred to us with either diagnosed or undiagnosed illnesses which would be of interest to our teaching program or which would serve as a source of patients to subsequently be entered into established, ongoing protocol studies. Such patients will be admitted to the protocol and handled according to accepted medical practice of diagnosis and treatment....

In addition to microbiota-host interaction on inflammatory response, many enzymes, including three enzymes critical in gluconeogenesis and transport of amino acids and carbohydrates in energy metabolism, are dependent on the Ca/Mg ratio, indicating critical roles of the Ca/Mg ratio in carbohydrate fermentation and energy metabolism in bacteria. In pilot metagenomic study conducted by the investigators, they found all the significantly changed biologic functions within the microbial community caused by a reduction in the Ca/Mg ratio are biologically dependent on the Ca/Mg ratio or Mg. It is striking that the functions with significant changes in stool samples were centered on the fermentation of carbohydrates and energy metabolism while the functions in rectal swabs were related to immune response. Tissue also had a distinct profile from stool and swab. These findings have very broad clinical and public health significance for many inflammation-related diseases or metabolic disorders. Due to the small sample size in the pilot study, the investigators plan to confirm these findings using the biospecimens collected in the parent study (Personalized Prevention of Colorectal Cancer Trial, NCT01105169).

The precise and noninvasive evaluation of disease activity among patients with Crohn's disease is not easy, especially for children. It deals with clinical, biological, histological and radiological parameters. Bowel sounds (BS) when evaluated by a stethoscope are modified by several factors including surgery, infection, drugs or intestinal inflammation. These factors can interact on intestinal motricity. There is a direct relationship between gastrointestinal motility and characteristics of BW. The study of BS using a stethoscope is a simple method, although operator dependent and subjective,with a wide inter and intraindividual variability. Some studies among adults showed interest in the spectral analysis of BS to assess gastrointestinal motility. This more precise and reproducible method is not operator dependent. To date, no such study has evaluated the correlation between disease activity and the spectral pattern of BS. of this project is to assess the correlation between disease activity and the spectral pattern of BS in pediatric Crohn's disease.
