Inflammatory Bowel Disease (IBD) in pregnancy: analysis of the possible effects of the disease on the fetus and the newborn and therapeutic approaches

2015

The Inflammatory Bowel Diseases(IBD), are a group of inflammatory diseases characterized by the presence of chronic inflammation, i the absenc of infectious ethiology. The two most well-known diseases in this group are: Crohn's disease (CD) and Ulcerative Colitis (UC). In cases where iti is not possible to distinguish between CD and UC, it is called Indeterminated Colitis. IBD can affect women pregnant. The causes of IBD are unknown, and the clinical course of the sdisease is characterized by phases of activity and remission. UC is a chronic inflammation of the mucosa of the colon and involving predominantly the left colon and rectum. It is associatred with presence of blood and mucus in th…

INFLAMMATORY BOWEL DISEASE AND EXTRAINTESTINAL MANIFESTATIONS

2022

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, are chronic and recurrent inflammatory diseases. Although the typical symptoms are localized in the gastrointestinal tract, there are also extraintestinal manifestations (EIMs) associated with IBD, probably caused by immune reactions secondary to the pathology of origin. Anybody can be affected by EIMs, which can be dermatological, pulmonary, ocular, musculoskeletal, hepatobiliary and neurological, et al. This represents a therapeutic challenge for clinicians, who must first establish a diagnostic and then a multidisciplinary therapeutic path, in order to guarantee an optimal quality of life for the patient.

Regulation of T-cell apoptosis in inflammatory bowel disease: to die or not to die, that is the mucosal question.

2001

T-cell resistance against apoptosis contributes to inappropriate T-cell accumulation and the perpetuation of chronic mucosal inflammation in inflammatory bowel diseases (IBDs). Anti-interleukin-12 (IL-12) and anti-IL-6 receptor antibodies suppress colitis activity by the induction of T-cell apoptosis. These findings have important implications for the design of effective treatment regimens in IBD.

Adaptation of TECCU App Based on Patients´ Perceptions for the Telemonitoring of Inflammatory Bowel Disease: A Qualitative Study Using Focus Groups

2020

Background: Despite the continuous adaptation of eHealth systems for patients with inflammatory bowel disease (IBD), a significant disconnection persists between users and developers. Since non-adherence remains high, it is necessary to better understand the patients&rsquo

New Biodegradable Hydrogels Based on Inulin and α,β-Polyaspartylhydrazide Designed for Colonic Drug Delivery: In Vitro Release of Glutathione and Oxy…

2010

Succinic derivatives of inulin (INU-SA) with two different degrees of derivatization (20% and 30%, mol/mol) were cross-linked with α,β-polyaspartylhydrazide (PAHy) to obtain INUPAHy hydrogels. Cross-linking was performed using N-ethyl-N-(3-dimethylaminopropyl)-carbodiimide hydrochloride (EDC) and N-hydroxysulfosuccinimide (NHSS) as coupling agents and by varying the reaction time (4 h, 8 h and 24 h). All samples prepared were characterized by FT-IR analysis and swelling measurements in different media. In vitro assays, performed in the presence of inulinase, demonstrated the degradability of the prepared hydrogels. Cell compatibility was evaluated using Caco-2 cells through both direct and …

T-bet and mucosal Th1 responses in the gastrointestinal tract

2002

T cells play an essential role in regulating mucosal immune responses in the gastrointestinal tract. Recent observations on T helper cell differentiation and activation by regulatory transcription factors-especially T-bet-in chronic inflammatory diseases have provided new perspectives for understanding mucosal immunity. Here we summarise recent advances in the field of transcription factors and discuss the implications of these findings for future therapeutic approaches in inflammatory bowel diseases. In particular, we have focused on the role of T-bet in controlling mucosal Th1 responses in the gastrointestinal tract.

VEGF receptor signaling links inflammation and tumorigenesis in colitis-associated cancer.

2010

Inflammation drives expression of VEGFR2, which is expressed on and drives growth of tumor cells in colitis-associated cancer.

DNASE1L3 deficiency, new phenotypes, and evidence for a transient type I IFN signaling.

2022

Background: Deoxyribonuclease 1 like 3 (DNASE1L3) is a secreted enzyme that has been shown to digest the extracellular chromatin derived from apoptotic bodies, and DNASE1L3 pathogenic variants have been associated with a lupus phenotype. It is unclear whether interferon signaling is sustained in DNASE1L3 deficiency in humans. Objectives: To explore interferon signaling in DNASE1L3 deficient patients. To depict the characteristic features of DNASE1L3 deficiencies in human. Methods: We identified, characterized, and analyzed five new patients carrying biallelic DNASE1L3 variations. Whole or targeted exome and/or Sanger sequencing was performed to detect pathogenic variations in five juvenile …
