There was a trend towards patient preference for infliximab (iv) treatment as opposed to adalimumab (sc) in patients with IBD. This difference may be due to the frequency of administration, mode of administration or differing 'times in the market-place', as infliximab had been approved for a longer period of time in Crohn's disease. Further studies are required in IBD patients to investigate whether patient choice will affect compliance, patient satisfaction and efficacy of treatment with anti-TNF therapies.

Interstitial cystitis is a chronic, debilitating disease of the bladder. Treatments using intravesicular inoculation of long-chain polysaccharide formulations, such as hyaluronic acid or anti-inflammatory agents, have been used to some effect. The objective of this study was to test a long-chain polysaccharide derivative of chitosan as a vehicle for delivery of the anti-inflammatory agent 5-aminosalicylic acid (5-ASA) for treatment of inflammation in the bladder.

Ileal pouch anal anastomosis (IPAA) is the standard procedure for reconstruction after colectomy for ulcerative colitis (UC). However, ileorectal anastomosis (IRA) as an alternative has, recently experienced a revival. This study from a single center compares the clinical outcomes of these procedures.
The mean annual total expenditure on health care was 1871 Euro/patient-year for inflammatory bowel disease, 1524 Euro/patient-year for ulcerative colitis, and 2548 Euro/patient-year for Crohn's disease (P < .001). The most expensive resources were medical and surgical hospitalizations, together accounting for 63% of the cost in Crohn's disease and 45% in ulcerative colitis. Total and hospitalization costs were much higher in the first year after diagnosis than in subsequent years. Differences in medical and surgical hospitalizations were the primary cause of substantial intercountry variations of cost; the mean cost of health care was 3705 Euro/patient-year in Denmark and 888 Euro/patient-year in Norway. The outlay for mesalamine, a costly medication with extensive use, was greater than for all other drugs combined. Patient age at diagnosis and sex did not affect costs.
Ninety-nine patients with mild or moderate UP limited to 15 cm of the anal margin, evidenced by a disease activity index (DAI) between 4 and 11, were randomized to 5-ASA 500 mg suppository (Canasa; Axcan Pharma) BID or 1 g at bedtime (HS) for 6 weeks. The study used a noninferiority hypothesis based on the mean difference in DAI values after 6 weeks of treatment on an intent-to-treat basis using analysis of covariance. DAI was derived from a composite of the measures of stool frequency, rectal bleeding, mucosal visualization at endoscopy, and general well being.

The newer 5-ASA preparations were superior to placebo and tended towards therapeutic benefit over SASP. However, considering their relative costs, a clinical advantage to using the newer 5-ASA preparations in place of SASP appears unlikely. This review updates the existing review of oral 5-aminosalicylic acid for induction of remission in ulcerative colitis which was published in the Cochrane Library (Issue 1, 2006).

Five different mesalamine formulations (Asacol® 400 mg, Mezavant® 1200 mg, Pentasa® 500 mg and Salofalk® in the 250 mg and 500 mg strengths) were investigated with biorelevant dissolution methods using the USP apparatus III and USP apparatus IV (open loop mode) under both fasted and fed state conditions, as well as with the dissolution methods described in pharmacopeia for delayed and extended release mesalamine products.
Azathioprine and 6-mercaptopurine are orally administered immunosuppressive drugs which are effective for the treatment of Crohn's disease and ulcerative colitis. Azathioprine is rapidly converted to 6-mercaptopurine after administration. 6-Mercaptopurine is then either converted to the putative active metabolites, the 6-thioguinine nucleotides, or inactivated by the enzyme xanthine oxidase to 6-thiouric acid or alternatively inactivated to 6-methylmercaptopurine by the enzyme thiopurine methyltransferase. Thiopurine methyltransferase activity is genetically determined, with one in 300 patients having low or absent enzyme activity, one in 10 patients having intermediate enzyme activity, and 9 in 10 patients having normal enzyme activity. Patients with intermediate or low thiopurine methyltransferase activity are at risk for early leukopenia. Higher erythrocyte 6-thioguinine nucleotide concentrations are associated with a greater likelihood of clinical response. Azathioprine is modestly effective for Crohn's disease and ulcerative colitis. Toxicity associated with azathioprine includes infection and lymphoma. Anti-TNF therapy with infliximab, adalimumab, and certolizumab pegol is effective for induction and maintenance treatment of Crohn's disease, and infliximab is effective for ulcerative colitis. Toxicity associated with anti-TNF therapy includes infection and lymphoma. Combination therapy with infliximab and azathioprine is more effective for inducing and maintaining steroid-free remission and mucosal healing then monotherapy with either drug alone. Strategies to reduce immunogenicity of anti-TNF agents include combination therapy with azathioprine and administration of a loading dose followed by systematic maintenance dosing. Higher serum trough concentrations of infliximab occur more frequently in patients receiving combination therapy with azathioprine and are associated with better clinical outcomes. Combination therapy is associated with an increased relative risk of opportunistic infection, but is not associated with an increased absolute risk of serious infection. Clinical practice should change such that combination therapy with an anti-TNF agent and azathioprine replace azathioprine in patients failing first line therapy with mesalamine and/or steroids.

A total of 29 consecutive patients (mean age: 9.8 years; range: 1.7-16.1 years; female/male: 13/16) with newly diagnosed UC were randomized to receive either VSL#3 (weight-based dose, range: 450-1,800 billion bacteria/day; n=14) or an identical placebo (n=15) in conjunction with concomitant steroid induction and mesalamine maintenance treatment. Children were prospectively evaluated at four time points: within 1 month, 2 months, 6 months, and 1 year after diagnosis or at the time of relapse. Lichtiger colitis activity index and a physician's global assessment were used to measure disease activity. At baseline, within 6 months and 12 months or at the time of relapse, all patients were assessed endoscopically and histologically.

Pellet starter cores containing 60% 5-aminosalicylic acid were prepared by extrusion/spheronization and coated with different Eurylon 6 HP-PG:ethylcellulose blends at various coating levels. Drug release was measured in media simulating the contents of the upper gastrointestinal tract (in the presence and absence of enzymes) as well as in media simulating the contents of the colon.
We searched the National Library of Medicine/Pubmed for reported cases of DIP from 1966 to April 30, 2004. Medications implicated in AP are classified based on the strength of evidence into one of three classes of drugs associated with pancreatitis. We reviewed the top 100 prescription medications in the United States for their association with AP.

In this prospective, randomized, double-blind, placebo-controlled study, 48 healthy volunteers took EcN in a run-in phase for 17 days (5-50 x 10(9) viable bacteria od). If stool samples became positive for EcN, volunteers received combination treatment with EcN plus either mesalamine (1500 mg twice a day) or placebo for 1 week. Fecal samples were further tested for EcN in 2- to 3-day intervals until a maximum of 48 weeks after treatment. Patient diaries, blood, and urine were checked to assess safety, compliance, and tolerance.

A Markov cohort model was developed to assess the cost effectiveness of Mezavant compared with Asacol over a 5-year period in the German Statutory Health Insurance (SHI). Drug pricing details for 2009 were applied throughout the model, and overall resource use was determined and also fitted to 2009 from published results of a large cross sectional study of German SHI patients. Cost per quality adjusted life year (QALY) was the primary endpoint for this study. Remission rates were obtained using data from a randomised, phase III trial of Mezavant with an active Asacol reference arm and a long-term, open label, safety and tolerability trial of Mezavant. Uncertainty in the study model was assessed using one-way and probabilistic sensitivity analyses applying a Monte Carlo simulation.

Twenty-one patients were assigned to receive GTW and 18 to 5-ASA; two patients on GTW and one on 5-ASA were withdrawn. Clinical and endoscopic recurrences were less common in the GTW group (n = 4) versus the 5-ASA group (n = 9). There were improvements in Rutgeerts' scores for those taking GTW. Mean between-group CDAI scores were similar. No serious adverse events were reported.

Significantly more severe colitis, including necrosis, ulceration, and hemorrhage, was seen in colonic biopsies of rats with colitis when iron was supplemented. This pathology was attenuated when iron was given in combination with 5-ASA and/or lycopene. There was no significant benefit from adding Beta-carotene.
A significant increase in the body weight of rats was seen in the group given C. officinalis extract 3000 mg/kg orally, oral mesalamine, and 20% intracolonic gel form of marigold extract compared with negative control and base gel groups during the experimental period. Acute inflammation and granular atrophy after UC induction were resolved completely completely by both 20% intracolonic gel and 3000 mg/kg orally. An increase in MPO activity and a decrease in MDA level in response to oral and intracolonic gel form of C. officinalis were observed 3 and and 7 days after treatment (P < 0.05).

Steroid treatment failure in acute Crohn's disease and ulcerative colitis frequently necessitates surgical intervention. Several alternative therapeutic strategies have been raised. The most promising so far has been intravenous cyclosporine, but the results in the long term have been discouraging. We assessed the efficacy and safety of the new macrolide immunomodulator tacrolimus as an alternative to cyclosporine A.

Four double-blind and placebo-controlled studies used 5-aminosalycilates in the prevention of acute radiation enteritis. Only for sulphasalzine 2 g/d was a positive effect proven. Prophylactic administration of probiotics reduced the incidence of acute radiation enteritis in a large placebo-controlled trial. If acute radiation enteritis was present octreotide ameliorated radiation-induced diarrhoea in a randomised study. Two investigations, only one of them randomised, described the effectiveness of loperamide in the treatment of acute radiation enteritis. If diarrhoea was also the main symptom of chronic radiation enteritis, loperamide reduced stool frequency in a double-blind and placebo-controlled study. A retrospective analysis of severe cases of chronic radiation enteritis with obstruction and fistula indicated that parenteral nutrition at home was more effective than surgery.
Although the association between 5-ASA therapy and chronic tubulo-interstitial nephritis is clearly described in several case reports, this prospective study came to the reassuring conclusion that renal impairment in IBD patients is not frequently observed and is rarely associated with 5-ASA therapy.

Concomitant diagnosis of Crohn's disease and juvenile or adult-onset idiopathic arthritis is rare. It is possible that both conditions share some genetic or immunological defects although sufficient data are lacking. We describe herein the first case of a patient with adult-onset Still's disease who was diagnosed on follow up with concomitant Crohn's disease. A 38-year-old man diagnosed with adult onset Still's disease from the age of 24 was admitted in our hospital because of bloody diarrhea. On admission physical examination was unremarkable and all routine laboratory tests were normal except of Hg at 11.3 gr/dl, erythrocyte sedimentation rate at 27 mm/h and C-reactive protein at 14 mg/dl. Ileocolonoscopy revealed small aphthoid ulcers in the terminal ileum and capsule endoscopy revealed the source of bleeding and small aphthoid ulcers starting from the distal jejunum up to the terminal ileum. Terminal ileum biopsies were diagnostic of Crohn's disease and patient had started on therapy with mesalamine 2 gr/day and azathioprine 2mg/kg and is currently on multidisciplinary follow up. We review all literature on co-existence of Crohn's disease with chronic idiopathic arthritis and we discuss the possible difficulties in diagnosis and therapy of those patients also in the view of the new biological agents.

Sulfasalazine has been the mainstay of therapy for ulcerative colitis and Crohn's disease of the colon. More recently, it has become clear that 5-ASA is the active moiety of the compound and that the sulfapyridine component is responsible for most of the adverse responses to sulfasalazine. The modes of action of sulfasalazine and 5-ASA have not been determined despite active investigations. There has been great current emphasis on the development of delivery systems to allow maximum concentration of therapeutically active 5-ASA in the colon or other gastrointestinal mucosal locations. Olsalazine accomplishes this goal by creatively coupling two molecules of 5-ASA to each other by a diazo bond. Bacterial azoreductases uncouple the parent drug and deliver 5-ASA to the colonic mucosa. Several pharmaceutical manufacturers have devised variations in mesalamine (5-ASA) coatings designed to release in pH and time-related manners. Oral Rowasa, Claversal, and Asacol accomplish distal delivery with acrylic coating of tablets. Oral Pentasa seems unique in distributing 5-ASA throughout the small bowel as well as the colon by utilization of small ethylcellulose-coated microgranules. For this reason, Pentasa may be particularly useful in the treatment of small bowel Crohn's disease. There are no data to suggest that patients unresponsive to oral sulfasalazine will respond to 5-ASA in any form, although it is possible that better toleration of the 5-ASA formulations will allow more effective dosage levels to be delivered. There are also preliminary data supporting synergism between oral and topical rectal 5-ASA in certain patients.(ABSTRACT TRUNCATED AT 250 WORDS)
