Quality of life in Chinese patients with inflammatory bowel disease: validation of the Chinese translation of the Inflammatory Bowel Disease Questionnaire

BACKGROUND: Health-related quality of life is an important outcome measure in inflammatory bowel disease. The Inflammatory Bowel Disease Questionnaire is a quality of life questionnaire that has not been validated previously in Chinese patients with inflammatory bowel disease. AIM: To develop and validate a Chinese translation of the Inflammatory Bowel Disease Questionnaire, specifically determining its construct validity, discriminant ability, reliability and sensitivity to change. METHODS: We developed a Chinese version of the Inflammatory Bowel Disease Questionnaire. Chinese patients with Crohn's disease and ulcerative colitis completed the Chinese Inflammatory Bowel Disease Questionnaire and visual analogue scales measuring systemic, social, bowel and emotional well-being. Patients also completed a validated Chinese SF-36 generic quality of life questionnaire, the Crohn's disease activity index or the clinical activity index for ulcerative colitis. RESULTS: One hundred and thirty-five patients (59 with Crohn's disease and 76 with ulcerative colitis) were enrolled, 99 of whom also completed the Chinese Inflammatory Bowel Disease Questionnaire for a second time. The Chinese Inflammatory Bowel Disease Questionnaire correlated well with the SF-36 for all four domains (Spearman: r = 0.55-0.80), the Crohn's disease activity index (r = -0.62-0.72) and the clinical activity index for ulcerative colitis (r = -0.44-0.68), as well as with the visual analogue scales. The Chinese Inflammatory Bowel Disease Questionnaire accurately distinguished between active and inactive disease. Test-re-test reliability showed excellent intra-class correlation (0.76-0.92; all P < 0.001). The Chinese Inflammatory Bowel Disease Questionnaire was also sensitive to changes in disease activity (P < 0.05). CONCLUSION: The Chinese Inflammatory Bowel Disease Questionnaire is a valid and reliable test that correlates well with the patients' subjective well-being and clinical disease activity.     

Quality of life in patients with established inflammatory bowel disease: a UK general practice survey

BACKGROUND: The current understanding of quality of life impairment in inflammatory bowel disease has largely been derived from selected populations and may not reflect the experience of patients in the community, where fewer than half are likely to be under specialist care. AIM: To describe the health-related quality of life in a community-based sample of patients with established inflammatory bowel disease and explore its association with the type and extent of disease, gender, age, material deprivation and other factors. METHODS: Adults with established inflammatory bowel disease were identified systematically from the records of 23 family practices in north-east England. The health-related quality of life was assessed by self-completion of the UK Inflammatory Bowel Disease Questionnaire. RESULTS: Five hundred and fifty-six patients were sent the questionnaire and 409 (74%) gave usable replies. Lower scores (worse quality of life) were significantly associated with female gender, Crohn's disease, more extensive disease (ulcerative colitis) and being under specialist care. The mean health-related quality of life score was significantly lower in patients resident in more deprived districts, independent of the type and extent of disease. CONCLUSIONS: Most patients with established inflammatory bowel disease showed only minor impairment of their health-related quality of life. On average, women and those with Crohn's disease were relatively more affected. Clinicians responsible for the care of patients with inflammatory bowel disease should be aware of these more vulnerable groups.     

Minimal renal dysfunction in inflammatory bowel disease is related to disease activity but not to 5-ASA use

BACKGROUND: Conflicting data exist about proteinuria in inflammatory bowel diseases. It is still unclear whether the occurrence of proteinuria in inflammatory bowel disease patients is an extra-intestinal manifestation of disease or the result of adverse effects to medication, especially to aminosalicylates (ASA). METHODS: A total of 95 patients (51 with Crohn's disease and 44 with ulcerative colitis) were enrolled in the study. Disease activity was assessed by Crohn's Disease Activity Index (CDAI) or the Truelove index, respectively. Urine was collected over 24 h and protein excretion of specific marker proteins for tubular (alpha 1-microglobulin-alpha 1-MG) and glomerular (albumin-Alb, Immunoglobulin G-IgG) dysfunction was measured using a highly sensitive immunoluminometric assay. RESULTS: Out of 51 Crohn's disease patients, 20 showed elevated urinary alpha 1-MG. The amount of alpha 1-MGuria was strongly correlated to the CDAI (r=0.6, P < 0.001). Only four Crohn's disease patients showed slightly elevated values for glomerular proteins in urine. Similar results were obtained for ulcerative colitis: whereas only two ulcerative colitis patients showed albuminuria, tubular proteinuria was detected in 28 out of 44 ulcerative colitis patients. Proteinuria was strongly dependent on disease activity (P < 0.01) but was not related to ASA treatment. CONCLUSIONS: Proteinuria of tubular marker proteins occurs in the majority of inflammatory bowel disease patients and is related to disease activity rather than to ASA treatment. Tubular proteinuria seems to reflect a renal extra-intestinal manifestation of inflammatory bowel disease and may serve as a new relevant marker of disease activity.     

Granulocyteaphaeresis in steroid-dependent inflammatory bowel disease: a prospective, open, pilot study

BACKGROUND: Uncontrolled studies suggest that granulocyteaphaeresis might be useful in the management of active ulcerative colitis. AIM: To assess the efficacy of granulocyteaphaeresis treatment in active steroid-dependent inflammatory bowel disease. METHODS: We conducted a multicentre, prospective, open, pilot study in patients with steroid-dependent inflammatory bowel disease. All patients were started on 60 mg/day of prednisone; after 1 week, a five-session programme of granulocyteaphaeresis (once per week) was started. The steroid dose was tapered weekly if there was clinical improvement. Remission was defined as an inactive clinical activity index together with complete withdrawal of steroids at week 6. The patients were followed up for at least 6 months or until disease relapse. RESULTS: Twenty-six patients (14 ulcerative colitis, 12 Crohn's disease) were included. More than a half had been previously treated with immunomodulators. Remission was achieved in 62 and 70% of ulcerative colitis and Crohn's disease, respectively. During a median follow-up of 12.6 months, six of eight ulcerative colitis patients maintained their clinical remission; however, only one Crohn's disease patient remained in remission after the first 6 months of follow-up. CONCLUSIONS: Granulocyteaphaeresis is a safe treatment option in inflammatory bowel disease. A five-session programme of granulocyteaphaeresis seems to be efficient in the treatment of steroid-dependent ulcerative colitis, but not in Crohn's disease.     

Bile composition in inflammatory bowel disease: ileal disease and colectomy,but not colitis,induce lithogenic bile

BACKGROUND: Inflammatory bowel disease is a risk factor for gall-bladder stones, but there is controversy about the composition of these stones and whether such patients develop lithogenic bile. METHODS: In 54 gallstone-free inflammatory bowel disease patients and 13 non-inflammatory bowel disease patients with cholesterol-rich gallstones, we measured the biliary cholesterol saturation indices, nucleation times and bilirubin concentrations, and determined the bile acid composition and molecular species of phosphatidylcholine, in gall-bladder bile. RESULTS: Patients with Crohn's colitis or ulcerative colitis had less saturated bile (mean cholesterol saturation index, 0.9) and longer nucleation times (median, 21 days) than those with ileal Crohn's disease (1.5; 14 days) or those who had undergone colectomy (1.6; 5 days). In patients with ileal Crohn's disease, the mean biliary bilirubin concentration was two- to three-fold higher than that in the other groups, and was associated with a decrease in the percentage of biliary deoxycholate and an increase in the percentage of ursodeoxycholate, compared with disease controls, but phosphatidylcholine species were similar. CONCLUSIONS: Patients with small bowel Crohn's disease, or who have undergone colonic resection, have supersaturated bile and an increased risk of cholesterol gallstone formation. In patients with ileal disease, the presence of high biliary bilirubin concentrations and low percentage of deoxycholic acid may also favour the formation of mixed, pigment-rich, gallstones.     

Basiliximab (anti-CD25) in combination with steroids may be an effective new treatment for steroid-resistant ulcerative colitis

BACKGROUND: Steroid resistance represents a major clinical problem in the treatment of ulcerative colitis. In vitro, interleukin-2 renders lymphocytes steroid resistant. AIM: To explore the therapeutic potential of interleukin-2 receptor blockade in steroid-resistant ulcerative colitis with both in vitro measures and a pilot in vivo study. METHODS: Ten patients with steroid-resistant ulcerative colitis received a single bolus of 40 mg of intravenous basiliximab plus steroid treatment in an open-label, uncontrolled, 24-week study. The outcome was assessed using the Ulcerative Colitis Symptom Score, rectal biopsy and Inflammatory Bowel Disease Questionnaire. Lymphocyte steroid sensitivity was measured in vitro in 39 subjects in the presence or absence of basiliximab. RESULTS: Nine of the 10 patients achieved clinical remission within 8 weeks. At 24 weeks, seven patients were in clinical remission. Marked improvement in the Ulcerative Colitis Symptom Score was seen by 1 week (P = 0.004) and on rectal biopsy and Inflammatory Bowel Disease Questionnaire by 2 weeks (both P < 0.05). Improvements persisted to 24 weeks (Ulcerative Colitis Symptom Score, Inflammatory Bowel Disease Questionnaire, both P < 0.005). Eight of the nine responders relapsed (median, 9 weeks), but remission was re-achieved with further corticosteroids and the addition of azathioprine. At 24 weeks, seven patients were in full clinical remission, five off all steroid therapy. In vitro measurement of lymphocyte steroid sensitivity demonstrated steroid resistance in 22% of subjects. All were rendered steroid sensitive in the presence of basiliximab. CONCLUSIONS: Basiliximab appears to be effective at inducing remission in steroid-resistant ulcerative colitis. In vitro, basiliximab also produced a dramatic increase in lymphocyte steroid sensitivity in healthy subjects. Confirmation in randomized controlled studies is required.     

Oral budesonide in the treatment of chronic refractory pouchitis

BACKGROUND: Pouchitis is the major long-term complication after ileal-pouch nal anastomosis for ulcerative colitis. Ten to 15% of patients develop a chronic pouchitis, either treatment responsive or treatment refractory. AIM: To evaluate the efficacy of oral budesonide in inducing remission and improving quality of life in patients with chronic refractory pouchitis. METHODS: Twenty consecutive patients with active pouchitis, not responding after 1 month of antibiotic treatment were treated with budesonide controlled ileal release 9 mg/day for 8 weeks. Symptomatic, endoscopic and histological evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of Pouchitis Disease Activity Index clinical score of < or = 2, endoscopic score of < or = 1 and total Pouchitis Disease Activity Index score of < or = 4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS: Fifteen of 20 patients (75%) achieved remission. The median total Pouchitis Disease Activity Index scores before and after therapy were, respectively, 14 (range 9-16) and 3 (range 2-10) (P < 0.001). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 105 (range 77-175) to 180 (range 85-220) (P < 0.001). CONCLUSION: Eight-week treatment with oral budesonide appears effective in inducing remission in patients with active pouchitis refractory to antibiotic treatment in this open-label study.     

Risk-benefit assessment of drugs used in the treatment of inflammatory bowel disease.

Although the aetiology of inflammatory bowel disease remains elusive, many agents are available for the control of symptoms and inflammation. Knowledge of drug pharmacology, indications and side effects is essential to ensure the best possible clinical care while minimising toxicity and inappropriate use. Sulfasalazine consists of sulfapyridine linked to mesalazine (5-aminosalicylic acid) via an azobond. Its use is indicated in the treatment of mild to moderately active ulcerative colitis and in the prevention of relapse in patients with quiescent disease. Patients with mild to moderate colonic or ileocolonic Crohn's disease also benefit from this drug, as do a proportion of patients with isolated small bowel disease. Sulfasalazine has not been uniformly effective in preventing relapse in Crohn's disease, although many clinicians continue its use in patients who respond initially. A high incidence of side effects which limit therapy include intolerance, hypersensitivity reactions and impairment of male infertility. The newer aminosalicylates offer targeted delivery of mesalazine to the bowel, with fewer side effects. Topical mesalazine has proved extremely effective in patients with distal ulcerative colitis; oral forms are effective in the treatment of mild to moderately active ulcerative colitis and in relapse. Both types appear to be effective in the treatment of Crohn's disease, and possibly in preventing relapse. There is no current clinical advantage of one mesalazine preparation over another, nor is there an indication for their use in sulfasalazine-treated patients who have satisfactory response without adverse effects. Corticosteroids are indicated for more severe disease activity where the aminosalicylates have limited efficacy-specifically to induce remission in patients with severe or refractory ulcerative colitis or Crohn's disease. They should not be used to maintain disease remission or in the prevention of postoperative recurrence. Topical corticosteroids allow their local use in distal colitis with minimal systemic side effects. Long term use is limited by side effects, many of which are dose related, although alternate-day therapy may lessen the incidence. Immunosuppressive agents are beneficial for the treatment of refractory inflammatory bowel disease unresponsive to other medications, and may also facilitate the withdrawal of steroids in refractory patients. Mercaptopurine has an added benefit in the treatment of Crohn's disease fistulae; the role of cyclosporin in bowel disease has not been established and its use cannot currently be recommended. The potential toxicity of immunosuppressive agents warrants careful consideration of their use by both physician and patient. Metronidazole is indicated for the treatment of mild to moderate Crohn's disease, including perineal disease. Common side effects include peripheral neuropathy and nausea.(ABSTRACT TRUNCATED AT 400 WORDS)     

Immune abnormalities and endotoxemia in patients with ulcerative colitis and in their first degree relatives: attempts at neutralizing endotoxin-mediated effects

Proinflammatory cytokines released from monocytes/macrophages, in particular tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, IL-6, and IL-8 seem to play an important role in Inflammatory Bowel Disease (ulcerative colitis and Crohn's disease). Endotoxins or lipopolysaccharides, derived from the outer membrane of Gram-negative bacteria interact with CD14 on surface membrane of macrophages, thus triggering a signal cascade, which leads to the production and release of proinflammatory cytokines, particularly TNF-alpha. Therefore, in IBD, lipopolysaccharides could play a pathogenic role. In this respect, plasma endotoxins have been demonstrated in a not negligible percentage of patients with ulcerative colitis and in their unaffected relatives. The presence of circulating endotoxins could be due, at least in part, to the impaired natural immunity in either patients with ulcerative colitis or in their first degree unaffected relatives. Lactoferrin is an iron-binding glycoprotein, which binds to the lipid A region of lipopolysaccharide with a high affinity and this interaction prevents the binding of lipopolysaccharide to CD14, thus inhibiting the release of proinflammatory cytokines. Therefore, based on the possible pathogenic role exerted by endotoxins in ulcerative colitis, lactoferrin may deserve attention as a possible therapeutical agent in experimental models of Inflammatory Bowel Disease.     

Glucose metabolism and insulin sensitivity in inactive inflammatory bowel disease

BACKGROUND: Inflammatory mediator concentration was found to be increased in active inflammatory bowel disease, and this could be related to an insulin-resistant state. Moreover, glucocorticoids, which are widely used in the treatment of inflammatory bowel disease, are notoriously related to insulin resistance. AIM: To measure body composition, whole body glucose uptake and oxidation in Crohn's disease and ulcerative colitis patients with inactive disease. METHODS: All patients had clinical, ultrasound and biochemical assessment. Body composition was determined by isotopic dilution technique; basal metabolic rate and substrate oxidation were measured by indirect calorimetry. Insulin sensitivity was assessed by the euglycaemic hyperinsulinaemic clamp. Ten patients with inactive Crohn's disease (five males, aged 31.1 +/- 7.0 years) and 10 patients with inactive ulcerative colitis (five males, aged 33.4 +/- 8.8 years) participated in the study. Forty healthy subjects, matched for age and height were used as a control group. RESULTS: Crohn's disease patients showed lower BMI (P < 0.001), fat mass (P < 0.05) and respiratory quotient (P < 0.001) values compared to both ulcerative colitis and control subjects. No difference in peripheral glucose uptake (micromol/kg/min) was found between groups (respectively 42.5 +/- 6.78 in Crohn's disease, 40.2 +/- 8.00 in ulcerative colitis and 41.4 +/- 10.8 in control subjects). Glucose storage and oxidation did not differ between groups. CONCLUSION: Our data showed that inflammatory bowel disease patients in a remission phase of the disease activity had a whole body glucose uptake and oxidation similar to those of control subjects, probably due to fat-free mass preservation and low blood and tissue cytokine concentration.     

A double-blind,randomized, placebo-controlled trial of essential fatty acid supplementation in the maintenance of remission of ulcerative colitis

BACKGROUND: Essential fatty acid supplementation has been found to ameliorate certain chronic inflammatory diseases. This effect is thought to be mediated through the modulation of eicosanoid synthesis. Pro-inflammatory eicosanoids have been implicated in ulcerative colitis. AIM: To investigate the possible therapeutic benefit of essential fatty acids in quiescent ulcerative colitis to reduce the frequency of disease relapse. METHODS: A randomized, double-blind, placebo-controlled study was performed with a treatment duration of 12 months. Patients with quiescent disease received either trial medication (gamma-linolenic acid, 1.6 g, eicosapentaenoic acid, 270 mg, and docosahexaenoic acid, 45 mg, per day) or placebo (sunflower oil, 500 mg/day). The primary end-point was disease activity, assessed by a previously validated clinical index, sigmoidoscopic appearance and histology. RESULTS: Sixty-three patients were randomized, 31 to receive essential fatty acid treatment and 32 to receive placebo. Disease relapse rates were similar at 12 months (placebo, 38%; essential fatty acids, 55%), as were changes in sigmoidoscopic grade from baseline. CONCLUSIONS: The supplementation of the diet with this combination of essential fatty acids does not prolong the period of disease remission of ulcerative colitis.     

Picotamide inhibition of excess in vitro thromboxane B2 release by colorectal mucosa in inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease is associated with increased mucosal release of eicosanoids. Among these, thromboxane A2 has been proposed as a possible inflammatory mediator; its suppression may be a useful therapeutic option. METHODS: Using a tissue incubation technique, we compared release of immunoreactive thromboxane B2 by colonic biopsies from patients with ulcerative colitis, Crohn's disease and controls, and assessed the inhibitory effect of picotamide, a thromboxane synthesis inhibitor-receptor antagonist, which has been widely used in Italy for management of ischaemic heart and cerebrovascular disease. RESULTS: Increased amounts of thromboxane B2 were released from biopsies from patients with active ulcerative colitis (median 238 pg/20 min/mg wet weight (interquartile range 147- 325), n = 12) and active Crohn's disease (252 (174-450), 6) compared with those from patients with quiescent ulcerative colitis (95 (61- 140), 12) or Crohn's disease (105 (57-201), 13), or controls (136 (64- 206), 8). Incubation with picotamide at concentrations between 100 microM and 1 mM reduced thromboxane B2 release (IC50 890 microM). CONCLUSION: Since increased thromboxane A2 production may have pathogenetic importance, thromboxane synthesis inhibitor-receptor antagonists such as picotamide merit therapeutic trial in the management of inflammatory bowel disease.     

Rofecoxib and early relapse of inflammatory bowel disease: an open-label trial

BACKGROUND: The safety and efficacy of selective cyclo-oxygenase-2 inhibitors in inflammatory bowel disease are under investigation. AIM: To assess, in a prospective, open-label trial, the efficacy and safety of rofecoxib (12.5 mg/day) in inflammatory bowel disease patients and controls. METHODS: The inflammatory bowel disease group included 45 inactive patients (25 Crohn's disease; 20 ulcerative colitis) with associated arthralgia. The control group included 30 dyspeptic patients. The efficacy and safety of rofecoxib were assessed in inflammatory bowel disease patients and controls before and after treatment (range, 3 days to 3 months). RESULTS: In inflammatory bowel disease, nine of the 45 patients (20%) required rofecoxib withdrawal due to gastrointestinal symptoms inducing clinical relapse, which subsided on drug discontinuation. The percentage of patients requiring rofecoxib discontinuation was comparable in patients with Crohn's disease and ulcerative colitis (20% vs. 20%), but was higher in inflammatory bowel disease patients than in controls (20% vs. 3%; P < 0.001). In inflammatory bowel disease, arthralgia relief was reported by 32 patients (71%): complete relief by eight patients (18%) and partial relief by 24 (53%). Thirteen patients (29%) reported no benefit. A comparable percentage of inflammatory bowel disease patients and controls reported arthralgia relief (71% vs. 70%). CONCLUSIONS: Rofecoxib appears to control arthralgia in almost two-thirds of inflammatory bowel disease patients. Side-effects requiring drug discontinuation are observed, however, in almost one-quarter of patients.     

Patients with refractory Crohn's disease or ulcerative colitis respond to dehydroepiandrosterone: a pilot study

BACKGROUND: Dehydroepiandrosterone is a steroid hormone used as an 'over-the-counter' drug in the USA. Treatment with dehydroepiandrosterone was effective in randomized controlled trials in patients with systemic lupus erythematosus. Dehydroepiandrosterone sulphate concentrations are decreased in patients with inflammatory bowel disease. Dehydroepiandrosterone inhibits nuclear factor-kappaB and the secretion of interleukin-6 and interleukin-12 via the peroxisome proliferator-activated receptor alpha. AIM: A phase II pilot trial was started to evaluate the effect of dehydroepiandrosterone in active inflammatory bowel disease. METHODS: Twenty patients with chronic active inflammatory bowel disease [seven Crohn's disease (Crohn's disease activity index, 242 +/- 51; mean +/- s.d.); 13 ulcerative colitis (clinical activity index, 7.8 +/- 2.1)] took 200 mg dehydroepiandrosterone per day orally for 56 days. RESULTS: Six of the seven patients with Crohn's disease and eight of the 13 patients with ulcerative colitis responded to treatment, with a decrease in the Crohn's disease activity index of > 70 points and a decrease in the clinical activity index of > 4 points, respectively. Six Crohn's disease patients and six ulcerative colitis patients went into remission (Crohn's disease activity index < 150; clinical activity index 相似文献   

Oral delayed-release mesalazine: a review of its use in ulcerative colitis and Crohn's disease

Oral delayed-release mesalazine is an enteric-coated formulation which releases mesalazine in the terminal ileum and colon. Up to 74% of patients with mild to moderately active ulcerative colitis experience endoscopic or symptomatic improvement (including remission) or both when treated with oral delayed-release mesalazine 2.4 to 4.8 g/day. There is a trend towards a better response in patients receiving higher daily dosages of oral delayed-release mesalazine, especially in patients with active distal disease. In patients with left-sided ulcerative colitis, oral balsalazide 6.75 g/day appears to be more effective than oral delayed-release mesalazine 2.4 g/day, but a higher dosage of oral delayed-release mesalazine 4.8 g/day may provide additional benefit in these patients. Oral delayed-release mesalazine 0.8 to 4.4 g/day appears to be as effective as sulfasalazine 2 to 4 g/day, prolonged-release mesalazine 1.5 g/day or balsalazide 3 g/day in maintaining remission in patients with ulcerative colitis. The optimal dosage of oral delayed-release mesalazine for the maintenance of remission is unclear. However, oral delayed-release mesalazine 1.6 g/day with rectal mesalazine 4g, administered twice weekly, was more effective than oral drug alone in maintaining remission in patients at high risk of relapse. In patients with left-sided or distal disease oral olsalazine 1 g/day appeared to be superior to oral delayed-release mesalazine 1.2 g/day for maintenance of symptomatic remission. Limited data in patients with Crohn's disease have shown oral delayed-release mesalazine 0.4 to 4.8 g/day to be an effective therapy for active disease (remission in up to 45% of patients) and for quiescent disease (relapse in 34% of recipients over a duration of up to 12 months). Preliminary data indicate that oral delayed-release mesalazine 2.4 g/day is effective in preventing postoperative recurrence of Crohn's disease. Oral delayed-release mesalazine is effective and well tolerated in sulfasalazine-intolerant patients with ulcerative colitis or Crohn's disease. CONCLUSIONS: Oral delayed-release mesalazine is effective in patients with mild to moderately active or quiescent ulcerative colitis. Available data suggest that patients with left-sided or distal ulcerative colitis are likely to require higher daily dosages of oral delayed-release mesalazine or supplementation with rectal mesalazine. Oral delayed-release mesalazine also appears to be effective in active and quiescent Crohn's disease. The drug is well tolerated and it appears to be effective in sulfasalazine-intolerant patients.     

The efficacy of methotrexate for maintaining remission in inflammatory bowel disease

BACKGROUND: The management of patients with inflammatory bowel disease who are resistant to or intolerant of azathioprine remains a challenge. Low-dose methotrexate has been shown to be effective in inducing remission in Crohn's disease. AIM: This review was conducted because there are limited long-term follow-up data during and after stopping treatment. There are also limited data on the use of methotrexate in ulcerative colitis. METHODS: The study was a retrospective review of clinical notes. Remission was defined as minimal bowel symptoms without the need for oral steroids for 3 months. Relapse was defined as bowel symptoms that required steroid treatment or surgery. RESULTS: Seventy patients were reviewed; 48 had Crohn's disease and 22 had ulcerative colitis. The mean duration of treatment was 17.1 months; the mean maintenance dose was 20 mg weekly. Remission was achieved in 34 of 55 patients who completed more than 3 months of treatment (62%). Life-table analysis showed that the chances of remaining in remission at 12, 24 and 36 months (if treatment was continued) were 90%, 73% and 51%, respectively. The chances of remaining in remission after stopping treatment at 6, 12 and 18 months were 42%, 21% and 16%, respectively. The dose of methotrexate (mg/kg) was associated with the induction of remission (P=0.02). Treatment was equally effective for Crohn's disease and ulcerative colitis. CONCLUSIONS: Maintenance methotrexate treatment gives acceptable remission rates for treatment periods up to 3 years. After stopping treatment, relapse is frequent and occurs early (usually within 1 year).     

Anti-TNF alpha therapy in the management of extraintestinal manifestation of inflammatory bowel disease

Inflammatory bowel disease, Crohn's disease and ulcerative colitis, are immune-mediated disorders of unknown etiology that primarily affect the gastrointestinal tract. In addition, other organ systems can be involved such as joint/bones, skin, eyes, hepatobiliary tract, lungs and kidney. Overall, they represent extraintestinal manifestations of inflammatory bowel disease and may present before, in conjunction or after the onset of bowel disease. Extraintestinal manifestations are observed in 20-40% of patients and frequently have a negative impact on quality of patients' life. Some extraintestinal manifestations such as arthritis, erytema nodosum, pyoderma gangrenosum, iritis, uveitis have a pathogenic tumor necrosis factor alpha-dependent mechanism common with Crohn's disease and ulcerative colitis. Early recognition and treatment of extraintestinal manifestations can minimize potential severe complications. In this review we provide an overview on the prevalence and clinical aspects of the more commonly reported extraintestinal manifestations of Crohn's disease and ulcerative colitis and the role of tumor necrosis factor alpha inhibitors in their treatment.     

Inflammatory bowel disease in the West Indies

Inflammatory bowel disease is generally assumed to be rare among negroes and Indians. Over 10 years 34 cases of ulcerative colitis and 14 cases of Crohn's disease were seen in one medical and one surgical unit in Port-of-Spain, Trinidad. Twenty-six patients were Negroes, 18 were Indians, three were of mixed race, and one was Caucasian. In many of these patients the disease was extensive and several of those with Crohn's disease suffered severe complications. The assumption that inflammatory bowel disease is rare among West Indians of African and Indian origin therefore seems to be wrong.     

The quantitative validation of non-endoscopic disease activity indices in ulcerative colitis

BACKGROUND: Ulcerative colitis disease activity indices have not been formally validated. AIM: To analise quantitatively the psychometric and performance validity of two non-endoscopic indices for ulcerative colitis, the Simple Clinical Colitis Activity Index and the Seo Index. METHODS: In 66 patients with ulcerative colitis, the measurement of disease activity was repeated with the two non-endoscopic indices, St Mark's Index, and the Inflammatory Bowel Disease Questionnaire. Psychometric validity was evaluated by measuring the content, construct, criterion-convergent and criterion-predictive validity on a 0-1 scale. Performance validity was evaluated by measuring the reproducibility and responsiveness on a 0-1 scale. RESULTS: The Simple Clinical Colitis Activity Index had good to excellent psychometric and performance validity, while the Seo Index had moderate to excellent psychometric validity and moderate to good performance validity. The Simple Clinical Colitis Activity Index had weaknesses in content validity and in responsiveness. The Seo Index had weaknesses in content validity, construct validity and responsiveness. CONCLUSIONS: These two non-endoscopic indices for ulcerative colitis have good psychometric and performance validity, and are now the most rigorously validated disease activity indices for ulcerative colitis. The Simple Clinical Colitis Activity Index appears to have better overall validity. Quantitative evaluation identifies weaknesses in disease activity indices, and can lead to better disease activity indices for ulcerative colitis.     

Oral beclomethasone dipropionate: a critical review of its use in the management of ulcerative colitis and Crohn's disease

Crohn's disease and ulcerative colitis are inflammatory bowel diseases characterised by a chronic relapsing course. Corticosteroids represent the mainstay of medical treatment of inflammatory bowel disease for the induction of remission. Despite the high efficacy of systemic steroids, their use is limited by the high incidence of potentially serious adverse effects. The topically acting steroids are synthetic compounds characterised by high anti-inflammatory activity and low systemic effects by virtue of efficient first-pass hepatic inactivation. Budesonide and Beclomethasone Dipropionate are the two most studied topically acting steroids in inflammatory bowel disease. Oral Budesonide has been extensively studied in the treatment of mild to moderate ileo-caecal Crohn's disease but few data are available concerning oral Beclomethasone Dipropionate. This review focuses on the available evidence of efficacy and safety of oral Beclomethasone Dipropionate in the management of ulcerative colitis and Crohn's disease and a possible role of this steroid in clinical practice is suggested.
