Abdominal actinomycosis is a rare infectious disease caused by Actinomyces israelii, a gram-positive anaerobic saprophyte germ that is a normal inhabitant of the upper intestinal tract in humans. Actinomyces israelii rarely cause abdominal infections or actinomycosis. Abdominal actinomysosis is characterised by fistulae and abscesses and may mimic cancer or inflammatory bowel disease. Abdominal actinomycosis is difficult to diagnose preoperatively, and often require surgical removal of the diseased tissue, allowing pathologists for giving the definitive diagnosis, revealed by characteristic "sulfur granules". The authors report herein the case of a 47-year-old man who presented with diarrhoea and abdominal pain. Abdominal computed tomography evoked complicated inflammatory bowel disease and surgical procedure was decided. Laparoscopic exploration did not provide further significant information, and laparotomy with diseased bowel resection was performed. Pathology demonstrated "sulfur granules" and allowed the diagnosis of abdominal actinomycosis. This case demonstrated that abdominal actinomycosis should be included in the differential diagnosis when computed tomography shows an infiltrative and inflammatory mass. [less ▲]

Ascites is the most common of the major complications of cirrhosis. The initial evaluation of a patient with ascites should include a history, physical evaluation and some investigations. Treatment should consist of treating the underlying liver disease, sodium restricted diet (2 g of Na+/day) and diuretics. This regimen is effective in 90 % of patients. The treatment options for the diuretic-resistant patients include serial therapeutic paracentesis, peritoneovenous shunting, TIPSand liver transplantation. The treatment and prophylaxis of spontaneous bacterial peritonitis which is a frequent and severe complication in cirrhotic patients with ascites is also important. The differential diagnosis with secondary bacterial peritonitisis is essential because the latter usually does not resolve unless patients are surgically treated. [less ▲]

Autoimmune pancreatitis has been characterised in 1995, but only a few cases have been published since then, most of them from Japan. This report describes the cases of two Belgian male patients who presented with isolated obstructive jaundice. Radiological imaging studies were highly suggestive of carcinoma of the head of pancreas and both patients underwent uneventful cephalic pancreaticoduodenectomy with portal vein resection. Pathological analysis of the removed tissues suggested an autoimmune process in both cases. Both patients had hyper-gammaglobulinemia and antinuclear antibodies, but failed to show evidence of any other autoimmune disease or cause of chronic pancreatitis. In both cases final diagnosis was autoimmune pancreatitis. Preoperative clinical suspicion of this diagnosis is mandatory and may avoid unnecessary surgery in future cases. [less ▲]

Crohn's disease (CD) is a chronic inflammatory disease of the bowel characterized by segmental transmural inflammation and granulomatous changes. TNF alpha is a member of a large family of proteins and receptors that are involved in immune regulation. It is a proinflammatory and immunoregulatory cytokine synthesized by monocytes, macrophages, and T cells. TNF alpha plays an early central role in the cytokine cascade of the inflammatory process. Recently, chimeric monoclonal antibodies that inhibits TNF alpha have been used in the treatment of Crohn's disease. Infliximab has been the most largely used antibody. It is commercialized in the USA and has recently obtained an European marketing approvement. Infliximab is indicated for the treatment of moderately to severely active CD in patients having an inadequate response to conventional therapy. Clinical trials have demonstrated efficacy when the agent is initiated as a 5 mg/kg single intravenous infusion. In patients with fistulizing CD, administration of 2 subsequent 5 mg/kg doses 2 and 6 weeks after the initial dose appears to be efficacious. Limited clinical data also suggest that infliximab retreatment regimen restores response and maintains remission rates. Infliximab appears to be well tolerated. To date, very little is known about the potential for long-term toxicity with infliximab therapy. [less ▲]

We examined immune and inflammatory activation during remission in patients with Crohn's disease who presented with various clinical profiles (prolonged remission vs. relapsing disease). Thirty-six patients with at least 3 years' follow-up starting from a remission period were studied retrospectively. Relapses were defined by a retrospective calculation of the Crohn's disease activity index or by the clinical judgement of the physicians in charge of the patients. Disease course over the study period was assessed by the mean number of annual relapses. Analysis used measurements during remission of the following: erythrocytes sedimentation rate, relative lymphocytosis, acid alpha1-glycoprotein, interleukin-6 (IL-6), and soluble interleukin-2 receptor (sIL-2R) serum levels. During the study period 21 patients experienced at least one relapse and 15 did not. Mean serum levels of sIL-2R and mean relative lymphocytosis in remission significantly discriminated between relapsing and nonrelapsing patients. Only the mean sIL-2R serum level was selected by multivariate analysis, with a cutoff value of 82 pM/1 (sensitivity of 76% and specificity of 80%). The only features correlated with mean number of annual relapses in the relapsing patients were mean serum levels of sIL-2R (r=0.58, P=0.015) and IL-6 in remission (r=0.45, P=0.039). Multivariate analysis demonstrated statistical significance only for the mean serum level of IL-6 (P=0.014). In Crohn's disease the persistent elevation in sIL-2R serum levels during remission corresponds to chronic active disease, while high serum levels of IL-6 in these patients is associated with a high frequency of relapse.

Gastro-oesophageal reflux is a frequent problem affecting up to one third of the Belgian adult population. It is most often a benign non evolutive disease. It is however frequently chronic, with a significant negative impact on quality of life. The diagnostic and therapeutic management must be adapted to each individual case. In the majority of cases, the purpose of therapy is the control of symptoms and, in a small number of cases with severe oesophagitis the aim is a complete and persistent healing of lesions. A Franco-Belgian consensus meeting on diagnostic and therapeutic management of gastro-oesophageal reflux disease in adults was recently held. Guidelines have been proposed. The aim of the present paper is to highlight the main principles of these guidelines and to comment on their adjustment to current belgian medical practice. [less ▲]

Inflammatory bowel diseases (IBD) are characterized by a sustained inflammatory cascade that gives rise to the release of mediators capable of degrading and modifying bowel wall structure. Our aims were (i) to measure the production of matrix metalloproteinase-3 (MMP-3), and its tissue inhibitor, tissue inhibitor of metalloproteinase-1 (TIMP-1), by inflamed and uninflamed colonic mucosa in IBD, and (ii) to correlate their production with that of proinflammatory cytokines and the anti-inflammatory cytokine, IL-10. Thirty-eight patients with IBD, including 25 with Crohn's disease and 13 with ulcerative colitis, were included. Ten controls were also studied. Biopsies were taken from inflamed and uninflamed regions and inflammation was graded both macroscopically and histologically. Organ cultures were performed for 18 h. Tumour necrosis factor-alpha (TNF-alpha), IL-6, IL-1beta, IL-10, MMP-3 and TIMP-1 concentrations were measured using specific immunoassays. The production of both MMP-3 and the TIMP-1 were either undetectable or below the sensitivity of our immunoassay in the vast majority of uninflamed samples either from controls or from those with Crohn's disease or ulcerative colitis. In inflamed mucosa, the production of these mediators increased significantly both in Crohn's disease (P < 0.01 and 0.001, respectively) and ulcerative colitis (P < 0.001 and 0.001, respectively). Mediator production in both cases was significantly correlated with the production of proinflammatory cytokines and IL-10, as well as with the degree of macroscopic and microscopic inflammation. Inflamed mucosa of both Crohn's disease and ulcerative colitis show increased production of both MMP-3 and its tissue inhibitor, which correlates very well with production of IL-1beta, IL-6, TNF-alpha and IL-10.

Crohn's disease (CD) is a multifactorial disease with genetic heterogeneity. TNF-alpha plays a key role in the development of the mucosal lesions. The aim of our work was to study a single base pair polymorphism located in the promoter region of TNF gene, in a large population of CD patients with well defined phenotypes. One hundred and ninety-three patients with CD and 98 ethnically matched controls were studied. The -308 single base pair polymorphism of TNF gene was studied using an allele-specific polymerase chain reaction. Genotype and allelic frequencies were compared between patients and controls and between subgroups of patients defined by sex, age at diagnosis, familial history, location of disease, type of disease, extra-intestinal manifestations, and response to steroid treatment. In 29 patients a measure of TNF-alpha production by colonic biopsies was performed. The frequency of the allele TNF2 as well as the proportion of carriers of the allele TNF2 were slightly but not significantly lower in CD than in controls (11.9% versus 14.8% and 21.5% versus 27.6%, respectively). A more prominent difference in frequencies of allele TNF2 and in proportions of TNF2 carriers was found when comparing subgroups of patients. The frequency of allele TNF2 was significantly higher in steroid-dependent than in non-steroid-dependent disease (28.1% versus 10.3%; Delta = 17.8%, 95% confidence interval (CI) = 6.3-29.5%, P = 0.0027) and tended to be higher in colonic than in small bowel disease and in fistulizing than in stricturing disease. Furthermore, TNF2 carriers tended to be more frequent in patients with steroid-dependent than non-steroid-dependent disease (43.8% versus 19.3%; Delta = 24.5%, 95% CI = 3.6-45.4%, P = 0.022), in patients with fistulizing than stricturing disease (26.5% versus 9.6%; Delta = 16.9%, 95% CI = 1. 1-32.6%, P = 0.036), and in patients with colonic than small bowel disease (26.5% versus 11.1%; Delta = 15.4%, 95% CI = -0.8-31.6%, P = 0.063). Finally, patients carrying at least one copy of allele 2 were found to produce slightly more TNF-alpha at the colonic level. The -308 TNF gene polymorphism may have a slight influence on the behaviour of CD. The carriage of allele 2 may favour steroid-dependent disease and to a lesser extent fistulizing and colonic disease, possibly secondary to a more intense TNF-alpha-driven inflammatory reaction at the mucosal level.

Severe colitis is life-threatening complication of ulcerative colitis. Early recognition of the severity of the colitis, intensive medical therapy and prompt surgery when necessary have all contributed to improved outcome. Initial medical treatment should be instituted as soon as the diagnosis is made with an intravenous corticosteroid associated with supportive treatment. If the patient fails to response to this intensive treatment after 5-7 days, cyclosporin should be initiated. If cyclosporin is not used then colectomy should be performed immediately. Moreover, significant deterioration at any point during medical therapy is an indication for colectomy. The gravity of the patient's condition require close interaction between physician an surgeon.

Crohn's disease is probably an heterogeneous entity. This heterogeneity may be linked to either genetics or environment. In particular the behaviour of the disease, i.e. the tendency to develop stricturing and/or penetrating lesions, may be linked to the genetic background. While epidemiological and clinical data suggest the relevance of these behavioural classifications, the progresses in the characterization of the immuno-inflammatory reaction in the bowel wall shed a new light on possible candidate genes for these genetic predispositions to various Crohn's disease behaviours. Association studies an linkage analysis focusing on growth factors, metalloproteinases and their tissue inhibitors as well as cytokines may bring new interesting data in this field. [less ▲]

The Hepatitis C virus (HCV) infects nearly 170 million people in the world. The major characteristic of virus C is its tendency to chronicity in more than 85% of cases. Generally asymptomatic, HCV infection may also evolve with time to cirrhosis and hepatocellular carcinoma. During the last few years, HCV-related end-stage cirrhosis has become the first cause of liver transplantation. In 10 years only, very significant progress has been made in the knowledge of the virus, not only in the field of diagnosis but also in therapy. Several consensus conferences taking last discoveries into account have been organized in order to promote recommendations useful for the management of hepatitis C patients. The aim of this short overview is to summarize practical recommendations that emerged recently from consensus meetings. [less ▲]

Two patients experienced episodes of acute pancreatitis shortly after starting treatment with interferon alfa-2b (IFN-alpha) for a chronic hepatitis C infection. The first patient was a 40-year-old man who developed acute pancreatitis after 15 weeks of treatment with 3 MU IFN-alpha subcutaneously (SC) 3 times weekly and 1200 mg ribavirin. After disappearance of symptoms and normalization of laboratory values, oral intake of solid foods and IFN-alpha therapy were restarted. Within hours, a relapse of acute pancreatitis occurred. A rechallenge with IFN-alpha 4 days later was followed by a prompt increase in serum lipase level, and IFN-alpha therapy was discontinued. The second patient was a 38-year-old man who developed acute pancreatitis 2 hours after SC administration of 5 MU IFN-alpha. Ultrasound endoscopy showed sludge in the gallbladder. The patient was rechallenged 5 weeks later with 3 MU IFN-alpha SC. Although serum amylase and lipase levels increased after readministration of IFN-alpha, treatment was continued. The patient was readmitted 2 weeks later with severe abdominal pain, and IFN-alpha administration was discontinued. Considering the temporal relationship between the start of IFN-alpha treatment and development of acute pancreatitis, the absence of other clear etiologic factors for acute pancreatitis, disappearance of symptoms after discontinuation of IFN-alpha, and positive reactions to rechallenge, IFN-alpha is the most probable cause for development of acute pancreatitis in these patients.

Gastro-oesophageal reflux (GER) is more frequent in asthmatic patients than in the community at large. A causative association between the two diseases is suspected. Twenty-four hour ambulatory intraoesophageal pH monitoring represents the golden standard for the diagnosis of GER. The medical and/or surgical treatment of reflux in asthmatic patients with GER can improve pulmonary symptoms and to a lesser extent pulmonary function. The selection of the patients who will benefit from a GER treatment is difficult. Some symptoms like intrinsic asthma, nocturnal crises, could predict a good response to GER treatment. [less ▲]
