UNLABELLED Pentraxin 3 (PTX3) is an acute phase protein strongly expressed by advanced atherosclerotic lesions. We investigated (a) PTX3 expression and secretion in subcutaneous adipose tissue (SAT) and omental visceral adipose tissue (VAT) obtained from 21 obese (37.4+/-8.15 yr) and 10 normal weight subjects (43.7+/-11.07 yr) and (b) the relationships of(More)
OBJECTIVE Malabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the changes of cholesterol metabolism induced by malabsorptive and restrictive(More)
OBJECTIVE Crohn's disease (CD) is a chronic inflammatory bowel disease characterised by a peculiar accumulation of mesenteric adipose tissue covering the inflamed intestinal wall. METHODS The authors characterised different adipose tissue compartments of patients with CD using morphological and molecular techniques and compared them to those of subjects(More)
BACKGROUND The BioEnterics Intragastric Balloon (BIB, BioEnterics, Santa Barbara, CA) in association with restricted diet has been used for the treatment of obesity and morbid obesity. METHODS Since March 1998, 322 BIB were placed in 281 obese and morbidly obese patients; 73 patients were male and 208 female; mean age was 41.6 years (21-70); mean weight(More)
Retrospective multicenter analysis of the results of two different approaches for band positioning: perigastric and pars flaccida. Data were collected from the database of the Italian Group for LapBand® (GILB). Patients operated from January 2001 to December 2004 were selected according to criteria of case–control studies to compare two different band(More)
OBJECTIVE The role of glucocorticoids production in adipose tissue in the development of metabolic disorders in humans has not been fully characterized. We investigated whether in obese subjects, 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) expression in subcutaneous (SAT) and visceral (VAT) adipose tissue is associated with the occurrence of(More)
BACKGROUND Limited information is available on weight loss, metabolic control, cardiovascular disease and diabetic complications in morbidly obese patients undergoing gastric banding (LAGB) compared with morbidly obese patients receiving medical treatment. OBJECTIVE To assess the long-term effects of laparoscopic adjustable gastric banding (LAGB) on(More)
BACKGROUND The major long-term complication of laparoscopic adjustable gastric banding (LAGB) is dilatation of the gastric pouch, that is reported with a frequency ranging from 1 to 25%, and often requires removal of the band. In addition to the usual recommendations of bariatric surgery centers and dietetic advice to prevent this complication, over the(More)
Crohn's disease (CD) is notably characterized by the expansion of visceral fat with small adipocytes expressing a high proportion of anti-inflammatory genes. Conversely, visceral fat depots in ulcerative colitis (UC) patients have never been characterized. Our study aims were a) to compare adipocyte morphology and gene expression profile and bacterial(More)
OBJECTIVE Lifestyle modifications and pharmacological interventions can prevent type 2 diabetes in obese subjects with impaired glucose tolerance. The aim of this study was to compare laparoscopic adjustable gastric banding (LAGB) and conventional diet (No-LAGB) in the prevention (primary intervention study; 56 vs. 29 patients) and remission (secondary(More)
