Accepted for publication 30 May 1996 Abstract Background-Increasing evidence points to a important role for inflammatory cytokines for the pathogenesis of Crohn's disease. Aim-To compare the secretion rate of tumour necrosis factor-a (TNF-a), interleukin-1 (IL-1 0) and interleukin-6 (IL-6) by morphologically normal and inflamed intestinal mucosa from(More)
BACKGROUND & AIMS Central venous catheter (CVC) infection is the most frequent complication during home parenteral nutrition (HPN). We prospectively assessed incidence and catheter-related sepsis (CRS)-associated factors in the 42 adult patients enrolled in our HPN centre since its opening. METHODS Age, frequency of infusions, CVC type, autonomy or(More)
BACKGROUND & AIMS Psoriasiform and eczematiform lesions are associated with anti-tumor necrosis factor (TNF)-α therapies. We assessed clinical characteristics, risk factors, and outcomes of skin disease in patients with inflammatory bowel diseases that presented with psoriasiform and eczematiform lesions induced by anti-TNF-α agents. METHODS We studied 85(More)
The maintenance of the physiological homeostasis of the gut mucosa characterized by continuous proliferation and differentiation processes results from epithelial-mesenchymal cell cross-talk. To set out stable and homogeneous models for the study of the (dys)regulation of various morphofunctional aspects, we established and characterized three clonal cell(More)
BACKGROUND Inflammatory cytokines, including tumour necrosis factor-alpha (TNF-alpha) and interleukin (IL)-1 beta, have been implicated as primary mediators of intestinal inflammation in inflammatory bowel disease. AIM To investigate the in vitro effects of oxpentifylline (pentoxifylline; PTX; a phosphodiesterase inhibitor) on inflammatory cytokine(More)
BACKGROUND Increasing evidence points to a important role for inflammatory cytokines for the pathogenesis of Crohn's disease. AIM To compare the secretion rate of tumour necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta) and interleukin-6 (IL-6) by morphologically normal and inflamed intestinal mucosa from patients with Crohn's disease.

BACKGROUND Modulation of cytokine secretion may be of interest in the treatment of Crohn's disease or ulcerative colitis. METHODS The effect of three antioxidants - butylated hydroxyanisol, tetrahydropapaveroline and nordihydroguaiaretic acid - on the production of tumour necrosis factor (TNF), interleukin (IL) 1, IL-6 and IL-8 (measured by enzyme-linked(More)
BACKGROUND/AIMS The aim of this study was to evaluate the treatment of common bile duct stones (CBDS) by endoscopic sphincterotomy (ES) and laparoscopic cholecystectomy (LC), ES being performed either pre-, per- or postoperatively. METHODS Between January 1990 and June 1997, 386 patients with a median age of 60 (range 18-92) years were treated for(More)
BACKGROUND & AIMS Immunomodulator therapy is effective for patients with Crohn's disease (CD) but has not been shown to affect disease progression, presumably because it is given too late after diagnosis. We compared the efficacy of early treatment (within 6 months after diagnosis) with azathioprine versus conventional management of patients at high risk(More)
