Mucosal immunoregulation: transcription factors as possible therapeutic targets.
2005
Much progress has been recently made with regard to our understanding of the mucosal immune system in health and disease. In particular, it has been shown that uncontrolled mucosal immune responses driven by lymphocytes or non-lymphoid cells may lead to immunological diseases such as allergy, hypersensitivity and inflammation. Thus, a more detailed understanding of mucosal immune regulation and decision making at mucosal surfaces is essential for a better understanding of mucosal immune responses in health and disease. Antigen presenting cells and T lymphocytes play a key role in controlling mucosal immune responses. To deal with this key task, T helper cells differentiate into functionally…
Microsporidia and Its Relation to Crohn's Disease. A Retrospective Study
2013
Background: The cause of Crohn's Disease (CD) remains unknown. Recently a decrease in the global lymphocyte population in the peripheral blood of CD patients has been reported. This decrease was more evident in gamma delta T lymphocytes, especially gamma delta CD8+T subsets. Furthermore, a decrease of IL-7 was also observed in these patients. We propose the hypothesis that microsporidia, an obligate intracellular opportunistic parasite recently related to fungi, in CD patients can take advantage of the lymphocytes and IL-7 deficits to proliferate and to contribute to the pathophysiology of this disease. Methods and Findings: In this case-control study, serum samples were collected from 36 C…
APHAMAX® ATTENUATES INFLAMMATORY AND OXIDATIVE STRESS IN 2, 4-DINITROBENZENE SULFONIC ACID-INDUCED COLITIS IN RAT AMELIORATING INTESTINAL FUNCTIONALI…
2021
Accumulating evidences indicate that inflammatory and oxidative stress play an essential role in the pathogenesis and progression of inflammatory bowel disease (IBD). In IBD the excessive production of reactive oxygen species (ROS) and nitrogen metabolites contribute to tissue injury and could have also a profound impact on gut functions, including motility. We characterised the inflammatory and oxidative condition and the impact on colon motility in an experimental rat model of colitis, the 2, 4-dinitrobenzene sulfonic acid (DNBS)- induced colitis, and we evaluated if oral treatment with a nat- ural extract of Aphanizomenon flos-aquae (AFA) AphaMax®, containing concentrated quantity of AFA…
Genetics and novel aspects of therapies in systemic lupus erythematosus.
2015
Autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, autoimmune hepatitis and inflammatory bowel disease, have complex pathogeneses and the factors which cause these disorders are not well understood. But all have in common that they arise from a dysfunction of the immune system, interpreting self components as foreign antigens. Systemic lupus erythematosus (SLE) is one of these complex inflammatory disorders that mainly affects women and can lead to inflammation and severe damage of virtually any tissue and organ. Recently, the application of advanced techniques of genome-wide scanning revealed more genetic information about SLE than previously possible. These case-contro…
Laboratory Tests in Crohn’s Disease
2015
Laboratory tests are useful for diagnosing Crohn’s disease, assessing disease activity, identifying complications, and monitoring response to therapy. Their role has been considered limited in the past due to lack of specificity. The introduction of biological therapies in inflammatory bowel disease (IBD) has renewed interest in inflammatory markers, especially C-reactive protein (CRP), given their potential to select responders to these treatments. There are several reasons why laboratory markers have been studied in IBD in the past decades: firstly, to gain an objective measurement of disease activity as symptoms are often subjective; secondly, to avoid invasive (endoscopic) procedures wh…
Psychopharmacology treatment and psychological interventions in irritable bowel syndromel
2013
Irritable bowel syndrome (IBS) accounts for 25% of gastroenterology output practice, making it one of the most common disorders in this practice. Psychological and social factors may affect the development of this chronic disorder. Furthermore, psychiatric symptoms and psychiatric diseases are highly prevalent in this condition, but the approach to treating these is not always straightforward. As emphasized in the biopsychosocial model of IBS, with regard to the modulatory role of stress-related brain-gut interactions and association of the disease with psychological factors and emotional state, it proves useful to encourage psychopharmacological treatments and psychosocial therapies, both …
Analysis of the Association between Fatigue and the Plasma Lipidomic Profile of Inflammatory Bowel Disease Patients
2020
Inflammatory bowel disease (IBD) is a chronic, relapsing noninfectious inflammatory condition of the intestinal tract with two main phenotypes, ulcerative colitis (UC) and Crohn's disease (CD), and globally increasing incidence and prevalence. Nearly 80% of the IBD patients with active disease and 50% of those with inactive disease suffer fatigue with significant impairment of their quality of life. Fatigue has been associated with multiple factors in IBD patients but, in most cases, no direct cause can be identified, and risk factors in clinically quiescent IBD are contradictory. Furthermore, as the assessment of fatigue is subjective, there is an unmet clinical need for fatigue biomarkers…
The Inflammatory Role of Platelets : Translational Insights from Experimental Studies of Autoimmune Disorders
2016
Beyond their indispensable role in hemostasis, platelets have shown to affect the development of inflammatory disorders, as they have been epidemiologically and mechanistically linked to diseases featuring an inflammatory reaction in inflammatory diseases like multiple sclerosis, rheumatoid arthritis and inflammatory bowel disorders. The identification of novel molecular mechanisms linking inflammation and to platelets has highlighted them as new targets for therapeutic interventions. In particular, genetic and pharmacological studies have identified an important role for platelets in neuroinflammation. This review summarizes the main molecular links between platelets and inflammation, focu…
Bone loss in inflammatory Bowel disease: our multicentric study
2011
Patients with inflammatory bowel disease are at increased risk of developing disorder in bone and mineral metabolism The study was aimed to determine if inflammatory bowel disease (IBD) is a risk factor for osteoporosis in 103 adult patients. We included 103 IBD patients, 67 patients with Crohn’s disease (CD) and 36 with ulcerative colitis (UC). Bone mineral density was measured by dual-energy X-ray absorptiometry. We used T score to express bone loss (osteopenia: -2.5 SD 2 years) and active disease would be risk factors of bone mineral loss in IBD.
Budesonide in previously untreated autoimmune hepatitis
2005
Background: Autoimmune hepatitis (AIH) is a chronic liver disease that is effectively treated with immunosuppressive therapy. Predniso(lo)ne, often in combination with azathioprine, is the basic therapeutic option to induce remission. However, this regimen can cause numerous side effects. The aim of the present study was to evaluate budesonide as a treatment option in the induction of remission in patients with previously untreated AIH. Methods: Between October 1998 and August 1999, 12 patients were treated with 3 mg budesonide thrice daily for 3 months in this open one-arm multicenter phase IIa study. Primary end point was induction of remission indicated by a drop of aspartate aminotransf…
