Azathioprine in inflammatory bowel disease: improved molecular insights and resulting clinical implications

2008

Azathioprine and 6-mercaptopurine represent important first-line immunosuppressive drugs in the treatment of inflammatory bowel disease. Owing to 45 years of clinical experience with thiopurines in inflammatory bowel disease, there currently exist strong data from numerous clinical trials and meta-analyses, which clearly document the therapeutic efficacy of azathioprine and 6-mercaptopurine in the treatment of inflammatory bowel disease. However, the exact molecular mechanism of action of these drugs was insufficiently understood for a long time. During the last few years, important new insights into the intracellular effects of azathioprine have been gained and thiopurines have been identi…

Clinical strategies for the management of intestinal obstruction and pseudo-obstruction. A Delphi Consensus study of SICUT (Società Italiana di Chiru…

2016

Intestinal obstructions/pseudo-obstruction of the small/large bowel are frequent conditions but their management could be challenging. Moreover, a general agreement in this field is currently lacking, thus SICUT Society designed a consensus study aimed to define their optimal workout.The Delphi methodology was used to reach consensus among 47 Italian surgical experts in two study rounds. Consensus was defined as an agreement of 75.0% or greater. Four main topic areas included nosology, diagnosis, management and treatment.A bowel obstruction was defined as an obstacle to the progression of intestinal contents and fluids generally beginning with a sudden onset. The panel identified four major…

HSP10,HSP70 AND HSP90 IMMUNOHISTOCHEMICAL LEVELS CHANGE IN ULCERATIVE COLITIS AFTER THERAPY

2011

Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) characterized by damage of large bowel mucosa and frequent extra-intestinal autoimmune comorbidities. The role played in IBD pathogenesis by molecular chaperones known to interact with components of the immune system involved in inflammation is unclear. We previously demonstrated that mucosal Hsp60 decreases in UC patients treated with conventional therapies (mesalazine, probiotics), suggesting that this chaperonin could be a reliable biomarker useful for monitoring response to treatment, and that it might play a role in pathogenesis. In the present work we investigated three other heat shock protein/molecular chaperones:…

Comparative analysis of Hsp10 and Hsp90 expression in healthy mucosa and adenocarcinoma of the large bowel.

2014

Heat shock proteins (Hsps) assist other proteins in their folding and drive the degradation of defective proteins. During evolution, these proteins have also acquired other roles. Hsp10 is involved in immunomodulation and tumor progression. Hsp90 stabilizes a range of "client" proteins involved in cell signaling. The present study evaluated the expression levels of Hsp10 and Hsp90 in normal mucosa and adenocarcinoma samples of human large bowel.Samples of normal mucosa and adenocarcinoma were collected and Reverse transcriptase-polymerase chain reaction RT-PCR, western blotting (WB) analyses, as well as immunohistochemistry were performed to evaluate the expression levels of Hsp10 and Hsp90…

Comparative analysis of Hsp10 and Hsp90 in large bowel healthy mucosa and adenocarcinomas

2015

Heat shock proteins (Hsps) are an important class of molecules with various functions. Their classic role is to assist other proteins in folding and re-folding and, when proteins are defective or irreversibly misfolded, to drive their degradation. For this reason, some Hsps are also named molecular chaperones. During evolution, this class of proteins has also acquired extrachaperoning roles such as participation in immune system regulation, cell differentiation, programmed cell death and carcinogenesis. Hsp10 is a partner of Hsp60 in the Hsp60/10 folding machine, but numerous scientific studies have shown that Hsp10 may also play other roles. In fact, Hsp10 seems to have an immunomodulatory…

HEAT SHOCK PROTEINS AND AUTOIMMUNE SYSTEM ACTIVATION IN IBD: ARTICULAR MANIFESTATIONS AND THE EPIDEMIOLOGICAL FREQUENCY IN ORTHPEDICS

2013

clinical evidence suggest that arthritis is one of the complications of inflammatori bowel disease (IBD) of which the etiological causes are still not completely understood. Among the possible explanations the most probable theory is poor regulation of the intestinal immune system, which causes a cross-like immune reactivity against the resident micro flora. Arthritis is these subjects involves different joints and is asymmetric, with greater involvement of the large joints of the lower limbs. Joints may also be involved with the spinal forms of sacroileitis and ankilosing spondylitis. This clinical evidence explains the existence of Lesnioski-Crohn's disease, a variant of IBD in which pati…

BONE AND JOINT MANIFESTATIONS IN PATIENTS AFFECTED BY INFLAMMATORY BOWEL DISEASE.

2011

Onset of the symptoms in patients with ulcerative colitis and Crohn's disease is sometimes characterized by osteoarticular manifestations. The usual presentation of peripheral arthritis is asymmetric, polyarticular and migrant, often involving large joints of the upper and lower limbs, unlike rheumatoid arthritis. This study analyses the statistical incidence of arthritic manifestations in elderly patients with inflammatory bowel disease.
