Changes in immunohistochemical levels and subcellular localization after therapy and correlation and colocalization with CD68 suggest a pathogenetic …
2011
In an earlier work, the role of heat shock protein (Hsp60) in the pathogenesis of ulcerative colitis (UC) was suggested by its significant increase in the pathological mucosa parallel with an increase in inflammatory cells. More data in this direction are reported in this work. We analyzed by immunohistochemistry biopsies of colon tissue from 2 groups of patients with UC and treated with either 5-aminosalicylic acid (5-ASA) alone or in combination with a probiotic. We looked for inflammatory markers and Hsp60. Both the treatments were effective in reducing symptoms but the group treated with both 5-ASA and probiotics showed better clinical results. Amelioration of symptoms was associated wi…
Toxic megacolon and human Cytomegalovirus in a series of severe ulcerative colitis patients
2015
Abstract Background Human Cytomegalovirus (HCMV) infection has been reported to be a cause of refractory ulcerative colitis (UC). Toxic megacolon (TM) is a rare but severe complication of an acute attack of UC. Objectives Aim of this study is to evaluate in a case-control study the association between HCMV and TM. Study design All patients who were admitted at Medicine Department of V. Cervello Hospital in Palermo (tertiary referral center) for a severe UC flare-up complicated by the onset of TM (diameter of the transverse colon > 6 cm) between January 1990 and November 2011 were identified through the electronic database. A total of 24 consecutive patients (16 male/8 female) with TM were i…
Impact of probiotics on risk factors for cardiovascular diseases. A review.
2014
International audience; Probiotic microorganisms have historically been used to rebalance disturbed intestinal microbiota and to diminish gastrointestinal disorders, such as diarrhea or inflammatory bowel diseases (e.g., Crohn's disease and ulcerative colitis). Recent studies explore the potential for expanded uses of probiotics on medical disorders that increase the risk of developing cardiovascular diseases and diabetes, such as obesity, hypercholesterolemia, arterial hypertension, and metabolic disturbances such as hyperhomocysteinemia and oxidative stress. This review aims at summarizing the proposed molecular and cellular mechanisms involved in probiotic-host interactions and to identi…
RHEUMATIC PATHOLOGIES IN SUBJECTS WITH INFLAMMATORY BOWEL DISEASE
2010
Inflammatory Bowel Disease (IBD) are commonly associated with rheumatic diseases of the joints. Sixty-five patients are selected during a 5-year study period. All Patients were analyzed with clinical, laboratory and radiographic exams. 38 patients had ulcerative colitis (mean age 42.1 years range:19-75) and 27 patients had Crohn's disease (CD) (mean age 37.2 years, range: 17-64 years). Arthritis occurred in 11 patients (17%): 7 with UC (18.4%) and 4 CD (14.8%). The mean age of patients with arthritis was 35 and mean disease duration of pain and limitation symptoms was 28 months. In 9 patients, arthritis appeared after the onset of bowel symptoms with mean duration of 20 months in UC and 24 …
Immunohistological differential diagnosis of inflammatory colonic diseases.
1984
Immunohistological investigations were carried out on human colonic tissue from, I healthy mucosa, 2 slightly inflamed mucosa, 3 mucosa with ulcerative colitis, 4 mucosa with Crohn's colitis, using antibodies against immunoglobulins and complement components. All our antibodies, including F(ab')2 fragments, demonstrated a progressive increase of labelled cells from healthy mucosa through slightly inflamed mucosa to mucosa with ulcerative colitis, in contrast to a complete absence of labelled cells in cases of Crohn's disease. The results are discussed with regard to their pathogenesis and their clinical significance for the differentiation of ulcerative colitis and Crohn's colitis.
INFLAMMATORY BOWEL DISEASE AND INFGERTILITY: ANALYSIS OF LITERATURE AND FUTURE PERSPECTIVES
2021
Background: inflammatory bowel diseases (IBD) are chronic disorders that affect the gastrointestinal tract but which also present extraintestinal manifestations. One of the problems related to IBD is the presence of bothfemale and male infertility. Aim: determine the correlation between IBD and male and female infertility by analyzing the literature. Material and method: studies carried out in the last twenty years have been selected through the PubMed search engine. Only studies were selected that in their conclusions showed a real correlation between IBD and infertility. Results: the first cause of infetility in both sexes is related to the surgical interventions that patients have to fac…
Argentum-quarz solution in the treatment of anorectal fistulas: Is it possible a conservative approach?
2012
Patients suffering from chronic intestinal diseases (Crohn's disease, Ulcerative Colitis, Indeterminate Colitis) are prone to the development of pyogenic complications. These complications are most commonly in the form of perianal or intraabdominal abscesses and/or fistulas. The treatment of these complications are managed differently but, after an initial treatment based on medical or minimally invasive management, the solution of the pathological condition is always achieved by a surgical procedure. In the last few years prospective studies have proposed an alternative conservative therapeutic approach based on application of fibrin glue in the healing of patients with fistulas-in-ano. In…
Endomicroscopy of Colon Pathology
2007
Colorectal cancer is still one of the leading causes of cancer-related death in the Western world. Screening colonoscopy is widely accepted as the gold standard for early diagnosis of cancer. The prognosis for patients with colonic neoplasms is strictly dependent on the depth of infiltration and therefore depends on early detection of pre-invasive and neoplastic changes. Early detection makes it possible to cure the patient by means of immediate endoscopic resection.
Colonoscopic surveillance in inflammatory bowel disease: state of the art reduction of biopsies.
2011
Longstanding colitis in inflammatory bowel disease (IBD) is associated with an increased risk for intraepithelial neoplasia (IN). White light endoscopy (WLE) with 40–50 random biopsies has been promoted for surveillance but may miss a significant proportion of lesions. In addition, the yield of random biopsies to detect IN is low, and random biopsies are expensive, labor-intensive and distract from scrutinizing the colon. Chromoendoscopy with targeted biopsies has proven its superiority over WLE in multiple randomized trials. It has been incorporated into many national and international guidelines. Virtual chromoendoscopy techniques carry the potential to provide contrast enhancement withou…
Involvement of IL-6 in the Pathogenesis of Inflammatory Bowel Disease and Colon Cancer
2005
Inflammatory bowel disease (IBD), which consists of Crohn’s disease and ulcerative colitis, is defined as a chronic inflammation of the gastrointestinbal tract. The etiopathogenetic mechanisms underlying the development of IBD are still not completely understood, and the therapeutic strategies used thus far have been limited to mostly evidence-based principles. There is growing evidence that the pro-inflammatory cytokine interleukin (IL)-6 plays a crucial part in the uncontrolled intestinal inflammatory process, which is a main characteristic of IBD. There is elevated production of IL-6 and its soluble receptor (sIL-6R) by intestinal macrophages and CD4+ T-cells. The increased formation of …
