Incomplete remission with short-term prednisolone treatment in collagenous colitis: a randomized study

BACKGROUND: Microscopic colitis is a disease of unknown aetiology characterized by chronic watery diarrhoea and diarrhoea can be eliminated by budesonide but frequently recurs when budesonide is stopped. We studied whether prednisolone could induce remission in patients with disabling, chronic diarrhoea due to microscopic colitis. METHODS: A double-blind, randomized (3:1) trial of oral prednisolone 50 mg daily or placebo for 2 weeks. Remission was defined as stool weight < or = 200 g/day or frequency < or = 2/day; effect was defined as > 50% reduction of either stool frequency or weight. Six centres screened 31 consecutive patients and included 11 with collagenous colitis and 1 with lymphocytic colitis. Median duration of diarrhoea was 9 months. Patients had a normal colonoscopy, and no evidence of coeliac disease, bile acid or lactose malabsorption. Patients with gastrointestinal infection, previous gastrointestinal surgery, abnormal biochemical screening or recent treatment with immunosuppressive agents were excluded. RESULTS: Stool weight (grams) declined in 7 of 9 patients given prednisolone and in 1 of 3 receiving placebo; changes in median weight were from 430 to 278 and from 825 to 489, respectively. Stool frequency (per day) declined from 6 to 3 and from 8 to 5. Remission was obtained in 2 and 0, and effect in 5 and 0, respectively (NS; Fisher exact test). CONCLUSIONS: Prednisolone 50 mg daily for 2 weeks induces incomplete remission in patients with chronic diarrhoea due to collagenous colitis.     

Budesonide treatment of collagenous colitis: a randomised,double blind,placebo controlled trial with morphometric analysis

BACKGROUND: Collagenous colitis is characterised by diarrhoea, lymphocytic inflammation, and a thickened subepithelial collagen layer in the colorectal mucosa. No standard treatment of the disease is established. AIMS: To investigate the clinical and histological effect of oral budesonide (Entocort, AstraZeneca) in the treatment of collagenous colitis. PATIENTS: Twenty patients with collagenous colitis (collagen layer >10 micro m) and diarrhoea (>4 stools/day and/or stool weight >200 g/day). METHODS: A randomised, double blind, placebo controlled trial of budesonide treatment. Patients were randomised to placebo or budesonide for eight weeks. Stool frequency and stool weight were registered before and after treatment. Sigmoidoscopy was performed before and after treatment, and biopsies at fixed locations were obtained for morphometric analysis. RESULTS: Ten patients were randomised to budesonide and 10 to placebo. All 10 patients receiving budesonide had a clinical response compared with two in the placebo group (p<0.001). In the budesonide group, stool weight was reduced from 574 g/day to 200 g/day and stool frequency was reduced from 6.2/day to 1.9/day (p<0.01). The histological inflammation grade in the sigmoid mucosa and the thickness of the collagen layer were significantly reduced. A correlation between the grade of inflammation as well as collagen layer thickness and stool weight was found. No side effects were reported. Eight of 10 patients had relapse of symptoms within eight weeks after stopping treatment. CONCLUSIONS: Budesonide is a highly effective and well tolerated treatment of collagenous colitis. There is a high risk of relapse after stopping eight weeks of treatment.     

Budesonide for the treatment of collagenous colitis: first results of a pilot trial

OBJECTIVE: Collagenous colitis is a chronic watery diarrhea disorder characterized by a subepithelial collagen layer and a lymphoplasmacytic infiltration within the lamina propria. However, no standard treatment has been introduced by controlled clinical trials. Aim of the present pilot trial was to investigate the clinical effects of orally administered budesonide (3 mg t.i.d.) in 7 patients with collagenous colitis. In addition, the histomorphological changes after budesonide treatment were described in a group of 3 patients. METHODS: The study was performed as an open label pilot trial. Study end point was the clinical remission of collagenous colitis defined by stool frequency and stool consistency. RESULTS: The results indicate a rapid and sustained clinical response in all patients. Stool frequency significantly decreased (p < 0.001) from 10.43 +/- 5.56 per day (4-20 per day) to 3.3 +/- 1.2 (1-5 per day) after 10 days and to 1.86 +/- 0.69 per day (1-3 per day) after 10 wk. Moreover stool consistency changed from watery (6 patients) or soft (1 patient) to soft (1 patient) or solid (6 patients). Clinical improvement was achieved within the first 10 days in all patients and maintained after dose reduction. In 3 patients no diarrhea recurred within 7, 12, or 15 months after treatment with budesonide was terminated. In these patients control biopsies were taken and showed a marked regression of both characteristics, the collagen band and the lymphoplasmacytic infiltration. CONCLUSIONS: With respect to the preliminary data from this pilot trial, budesonide with its high topical and low systemic effects seems to be of therapeutic clinical benefit in collagenous colitis. A therapeutic effect could be demonstrated for both therapeutic goals, the clinical response and morphological changes. Further studies on the effects of budesonide on mucosal collagen metabolism and long-term follow-up are warranted.     

Therapy of prednisone-refractory collagenous colitis with budesonide

Collagenous colitis is a rare cause of chronic watery diarrhea. No effective standard treatment has yet been established. Based upon anecdotal reports some anti-inflammatory and symptomatic drugs seem to have some therapeutic efficacy. Prednisone is widely believed to be the most effective treatment. Here we describe three female patients with histologically confirmed collagenous colitis refractory to therapy with prednisone. Each had received prednisone with a high starting bolus and lower dose maintenance therapy for their disease. However, definite clinical remission could not be achieved. After the administration of 3×3 mg/day controlled ileal release (CIR) capsules of budesonide the symptoms resolved immediately. The mean follow-up after beginning budesonide was 11 months (range 7–18). Two patients are still on budesonide. One had had a quick relapse of diarrhea after stopping her treatment. Budesonide therapy was therefore resumed. She has remained symptom-free on a lower daily dose of 2×3 mg/day budesonide. One patient has been in remission for more than 1 year after a 3-month course of budesonide. Budesonide is a topically acting steroid with rapid absorption, high receptor affinity, and low systemic bioavailability, thus causing almost no side effects. As yet only few case reports have been published on the use of budesonide for collagenous colitis. We present here the first three cases of prednisone refractory collagenous colitis successfully treated with budesonide. Accepted: 23 September 1998     

Oral budesonide therapy improves quality of life in patients with collagenous colitis

Introduction Collagenous colitis is an idiopathic microscopic colitis characterised by watery diarrhoea. The impact of collagenous colitis on quality of life has not been assessed. Our aim was to assess quality of life in patients with this condition and compare the effect of treatment with budesonide capsules or placebo on this parameter.Methods Patients with chronic diarrhoea and histologically-proven collagenous colitis were randomised to receive either budesonide controlled-release capsules (Entocort capsules, AstraZeneca, Lund, Sweden), 9 mg/day, or placebo for 6 weeks. Quality of life was measured using the validated Gastrointestinal Quality of Life Index (GIQLI) at baseline and after 6 weeks. With the GIQLI, scores range from 0 to 144, with higher scores representing better quality of life.Results Complete quality of life assessment was available in 29 patients (budesonide: n=17; placebo: n=12). At baseline, quality of life was low in patients with collagenous colitis (mean 76). After 6 weeks of treatment, the mean GIQLI score increased significantly in the budesonide group (from 67 to 92, p<0.001), but remained unchanged in the placebo group (86–88). The mean score of the dimensions symptoms (p=0.001), emotional functioning (p=0.003) and physical functioning (p=0.017) increased significantly in the budesonide group compared with the placebo group. A significantly larger proportion of patients in the budesonide group experienced improved stool consistency (p<0.01) and a significant reduction in the mean stool frequency compared with those in the placebo group (p<0.01).Conclusion Quality of life is seriously reduced in patients with collagenous colitis. Six-week treatment with oral budesonide controlled-release capsules significantly improves quality of life and clinical symptoms compared with placebo in these patients.     

Budesonide treatment and expression of inducible nitric oxide synthase mRNA in colonic mucosa in collagenous colitis

OBJECTIVE: In collagenous colitis, the production of nitric oxide in the colon is found to be 50 to 100-fold higher than in healthy controls. The role of nitric oxide in collagenous colitis is debated and it has been suggested that nitric oxide has a causative role in diarrhoea. The aim of this study was to examine the possible effect of budesonide treatment on the level of inducible nitric oxide synthase mRNA. METHODS: In 20 patients with collagenous colitis, clinical activity was assessed by registration of the daily stool frequency and stool weight. Sigmoidoscopy was performed and biopsies for histological examination and one biopsy for determination of inducible nitric oxide synthase mRNA was obtained in 16 patients. RESULTS: Budesonide treatment was followed by a significant reduction of inducible nitric oxide synthase mRNA (P<0.01) whereas no change was observed after placebo treatment. Significant correlations between inducible nitric oxide synthase mRNA and the grade of inflammation (rho=0.47; P<0.01), the daily stool weight (rho=0.51; P<0.005) and the daily stool frequency (rho=0.49; P<0.005) were observed. No significant association was observed between inducible nitric oxide synthase mRNA and the thickness of the collagen layer. CONCLUSIONS: In patients with collagenous colitis, treatment with budesonide results in a reduction of inducible nitric oxide synthase mRNA. The level of inducible nitric oxide synthase mRNA in colonic mucosa correlates with the inflammatory and clinical activity. The results support that nitric oxide is a central factor in the pathogenesis of collagenous colitis.     

The probiotic E. coli strain Nissle 1917 for the treatment of collagenous colitis: first results of an open-label trial

BACKGROUND: Collagenous colitis is clinically characterized by watery diarrhoea and can histologically be diagnosed by a thickening of the subepithelial collagen layer and an inflammatory infiltrate in the lamina propria. So far, the pathogenesis of collagenous colitis and the role of luminal factors remain unclear. METHODS: This clinical pilot investigation was conducted with an open-label design to monitor the clinical effects of EcN on stool frequency and stool consistency in 14 patients (11 female, 3male; age: 58.1 +/- 9.6 years). Due to the open-label protocol EcN was administered at different doses (1 - 6 capsules/day containing 2.5 - 25 x 10 (9) viable bacteria each). Except for two patients who discontinued treatment, therapy duration was at least 4 weeks. RESULTS: The results indicate a marked clinical response to the oral administration of EcN with a reduction of the stool frequency > or = 50 % in 9/14 (64 %) patients. Stool frequency clearly (p = 0.034) decreased from 7.6 +/- 4.8/day to 3.7 +/- 5.8/day at the end of therapy (between 4 and 18 weeks). Moreover, stool consistency changed in 7/14 patients from watery or slimy to soft (6 pts) and normal (1 pt), respectively. CONCLUSION: With respect to the preliminary data from this trial, the probiotic E. coli strain Nissle 1917 (EcN) seems to be of therapeutic clinical benefit in collagenous colitis. This may be explained with the recently shown antagonistic effect of EcN against Yersinia species, since a relevant number of patients suffering from collagenous colitis showed positive titres of serum IgG and IgA antibodies against Yersinia species. Further studies on the effects of EcN on mucosal collagen metabolism and long-term follow-up are warranted.     

Budesonide treatment for collagenous colitis: a randomized,double-blind,placebo-controlled,multicenter trial

BACKGROUND & AIMS: Collagenous colitis is an idiopathic microscopic colitis characterized by chronic watery diarrhea, a typical subepithelial collagen layer, and lymphoplasmacellular infiltration. We investigated the effect of budesonide on symptoms and histology in patients with collagenous colitis in a randomized, double-blind, placebo-controlled multicenter trial. METHODS: Patients with chronic diarrhea and histologically proven collagenous colitis were randomized to receive either oral budesonide (Entocort capsules; AstraZeneca, Sodertalje, Sweden) 9 mg/day for 6 weeks or placebo. Complete colonoscopy was performed before and after treatment. Histopathology was assessed by a single pathologist blinded to the patients' treatment. Clinical symptoms were assessed by standardized questionnaires. RESULTS: Fifty-one patients were randomized; 45 patients were available for per protocol analysis. The rate of clinical remission was significantly higher (P < 0.001) in the budesonide group than in the placebo group (per protocol 86.9% vs. 13.6%, respectively; intention-to-treat 76.9% vs. 12.0%, respectively). Histologic improvement was observed in 14 patients of the budesonide group (60.9%) and in 1 patient of the placebo group (4.5%; P < 0.001). Two patients in the budesonide group (7.7%) and 1 patient in the placebo group (4.0%) discontinued treatment prematurely because of side effects. CONCLUSIONS: Oral budesonide (Entocort capsules) is an effective and safe treatment modality for patients with collagenous colitis. Long-term follow-up of these patients is necessary to investigate whether clinical and histologic remission is sustained.     

Interventions for treating collagenous colitis: a Cochrane Inflammatory Bowel Disease Group systematic review of randomized trials

OBJECTIVES: To conduct a systematic review to determine effective treatments for patients with clinically active collagenous colitis. METHODS: Relevant articles were identified via the MEDLINE, PUBMED, and Cochrane Collaboration databases, manual searches of the references of identified articles, and review articles on collagenous or microscopic colitis, as well as searches of abstracts from major gastroenterological meetings. RESULTS: Five randomized trials assessing treatments for collagenous colitis were identified. One trial studying bismuth subsalicylate (nine 262 mg tablets daily for 8 wk) included 9 patients. Patients who received the bismuth preparation were more likely to have clinical (p= 0.003) and histological (p= 0.003) improvement than those who received placebo. In a trial comparing prednisolone (50 mg daily for 2 wk) to a placebo in 11 patients, a trend toward clinical response in patients on prednisone was reported (p= 0.064). The effect of prednisolone on histological improvement was not studied. A total of 94 patients were enrolled in three trials studying budesonide (9 mg daily or in a tapering schedule for 6-8 wk). The pooled odds ratio for clinical response to treatment with budesonide was 12.32 (95% CI: 5.53-27.46). The NNT (number of patients needed to treat with budesonide to achieve 1 improved patient) was 2 patients. This therapy was well tolerated. There was significant histological improvement with treatment in all three trials studying budesonide therapy. CONCLUSIONS: There is strong evidence that budesonide is effective and well tolerated for the treatment of collagenous colitis. The evidence for benefit with bismuth subsalicylate or prednisolone is weaker. It is not clear that any of these agents produce actual remission, as opposed to clinical and histological improvement of the disease.     

Contrasting Action of IL-12 and IL-18 in the Development of Dextran Sodium Sulphate Colitis in Mice

Background: Interleukin (IL)-12 and IL-18 are major interferon (IFN)- &#37 -inducing factors that collaborate with each other. The present study was conducted to determine the distinct roles of IL-12 and IL-18 in the development of dextran sulphate sodium (DSS) colitis in mice. Methods: Colitis was induced in IL-12p35 &#109 / &#109 , IL-18 &#109 / &#109 , IL-18 receptor &#109 / &#109 and control mice with DSS. Clinical and histopathological analysis was conducted using survival rate, weight loss score, diarrhoea score, bloody stool score and histological score. In addition, cytokine production by lamina propria mononuclear cells (LPMCs) was examined using the specific enzyme-linked immunoassay. Results: IL-12p35 &#109 / &#109 mice developed only a mild disease associated with no lethality and few histopathological abnormalities. In contrast, IL-18 &#109 / &#109 and IL-18R &#109 / &#109 mice developed more severe colitis associated with high lethality and more histopathological abnormalities compared with control mice. LPMCs from DSS-fed IL-18 &#109 / &#109 mice produced significantly higher amounts of IFN- &#37 , while LPMCs from DSS-fed IL-12 &#109 / &#109 mice produced lower amounts of IFN- &#37 and tumour necrosis factor (TNF)- &#33 compared with control mice. Conclusion: These results suggest that IL-18 might function with manners different from IL-12 at some pathological conditions in the development of colitis.     

布地奈德治疗胶原性结肠炎疗效和安全性的荟萃分析

背景:胶原性结肠炎以慢性水样腹泻和结肠黏膜上皮下胶原带增厚为特征,目前尚无标准治疗方案。目的:系统评价口服布地奈德治疗胶原性结肠炎的疗效和安全性。方法:计算机检索Cochrane Central Register of Controlled Trials(1995～2008.1)、MEDLINE/PubMed(1978～2009.12)、Ovid(1978～2009.12)、EMBASE(1978～2009.12)、中国期刊全文数据库(1980～2009.12)和万方数据资源系统(1980～2009.12),纳入所有口服布地奈德治疗胶原性结肠炎的随机对照试验(RCT),按Cochrane协作网推荐的方法进行荟萃分析。结果:共纳入5项RCT,包括179例患者,3项研究评价了诱导缓解治疗,2项评价了维持治疗。在诱导缓解方面,布地奈德的临床和组织学缓解率均优于安慰剂(OR=15.04,95% CI:5.47～41.33,P0.000 01;OR=34.02,95% CI:5.90～196.20,P0.0001)。在维持治疗方面,布地奈德的临床复发率和组织学缓解维持率亦优于安慰剂(OR=0.11.95% CI:0.04～0.31,P0.0001;0R=5.88,95% CI:1.90～18.17,P=-0.002)。布地奈德不良反应轻微,耐受性良好。结论:口服布地奈德能有效诱导并维持胶原性结肠炎的临床和组织学缓解,耐受性良好。由于本荟萃分析纳入研究的样本量较小,故应谨慎对待上述结论,并设计、开展大样本、高质量的RCT作进一步验证。     

Características epidemiológicas,clínicas y respuesta al tratamiento en 113 pacientes con colitis microscópica

ObjectiveTo study the epidemiological and clinical characteristics, and response to treatment in patients with microscopic colitis.Patients and methodEpidemiological, clinical, blood test and endoscopic data were retrospectively collected from 113 patients with microscopic colitis. Response to treatment was analyzed in 104 of them. Efficacy and relapse after treatment with budesonide were assessed using survival curves (Kaplan-Meier).Results78% of the patients were women, with a mean age of 65 ± 16 years. In smokers, the mean age was 10 years younger. 48% of them had some concomitant autoimmune disease; 60% suffered a single outbreak of the disease. The clinical presentation was similar in both subtypes, although patients with collagenous colitis had a chronic course more frequently (48% vs. 29%, p = 0.047). The remission rate with budesonide was 93% (95% CI 82-98). The cumulative incidence of relapse, after a median follow-up of 21 months, was 39% (95% CI 26-54%): 19% at one year, 32% at two years, and 46% at three years of follow-up. There were no differences in clinical response to budesonide based on smoking habit or microscopic colitis subtype.ConclusionsMicroscopic colitis is more frequent in elderly women. Smoking was associated with earlier onset of the disease, although it did not influence the clinical course or response to treatment. The majority (> 90%) of patients treated with budesonide achieved remission, although nearly half subsequently relapsed.     

Boswellia serrata extract for the treatment of collagenous colitis. A double-blind, randomized, placebo-controlled, multicenter trial

Background and aims The objective of this study was to investigate the effect of Boswellia serrata extract (BSE) on symptoms, quality of life, and histology in patients with collagenous colitis. Materials and methods Patients with chronic diarrhea and histologically proven collagenous colitis were randomized to receive either oral BSE 400 mg three times daily for 6 weeks or placebo. Complete colonoscopy and histology were performed before and after treatment. Clinical symptoms and quality of life were assessed by standardized questionnaires and SF-36. The primary endpoint was the percentage of patients with clinical remission after 6 weeks (stool frequency ≤3 soft /solid stools per day on average during the last week). Patients of the placebo group with persistent diarrhea received open-label BSE therapy for a further 6 weeks. Results Thirty-one patients were randomized; 26 patients were available for per-protocol-analysis. After 6 weeks, the proportion of patients in clinical remission was higher in the BSE group than in the placebo group (per protocol 63.6%; 95%CI, 30.8–89.1 vs 26.7%, 95%CI, 7.7–55.1; p = 0.04; intention-to-treat 43.8% vs 26.7%, p = 0.25). Compared to placebo, BSE treatment had no effect on histology and quality of life. Five patients discontinued BSE treatment prematurely. Discontinuation was due to adverse events (n = 1), unwillingness to continue (n = 3), or loss to follow-up for unknown reasons (n = 1). Seven patients received open-label BSE therapy, five of whom achieved complete remission. Conclusions Our study suggests that BSE might be clinically effective in patients with collagenous colitis. Larger trials are clearly necessary to establish the clinical efficacy of BSE.     

Collagenous colitis: a prospective trial of prednisolone in six patients

In a prospective study, the clinicopathological effect of prednisolone was evaluated in six patients with collagenous colitis. Prednisolone was associated with a significant decrease in stool frequency. However, the effect was transitory, since the diarrhoea recurred when prednisolone treatment was discontinued. There was a trend toward a diminished inflammatory response in the post-treatment biopsies, but the thickness of the collagen band remained unchanged, except in one patient. Until the results of further studies are available, we recommend that treatment with prednisolone be restricted to periods of acute diarrhoeal episodes.     

Budesonide versus prednisolone for the treatment of active Crohn's disease in children: a randomized, double-blind, controlled, multicentre trial

OBJECTIVES: Budesonide is a corticosteroid with low systemic bioavailability because of its high first-pass metabolism in the liver. In this paediatric, randomized, double-blind, double-dummy, controlled, multicentre trial, the safety and efficacy of budesonide versus prednisolone were evaluated in children with active Crohn's disease. METHODS: Forty-eight children, aged 6-16 years, with active Crohn's disease (Crohn's Disease Activity Index > 200) involving ileum and/or ascending colon were randomized to receive budesonide (9 mg/day for 8 weeks, 6 mg/day for 4 weeks) or prednisolone (1 mg/kg/day for 4 weeks, tapering for 8 weeks). RESULTS: The groups were comparable for age, sex, pubertal stage, disease activity and disease duration. Mean morning plasma cortisol concentration was significantly higher in the budesonide group (200 nmol/l) than in the prednisolone group (98 nmol/l) after 8 weeks, reflecting less adrenal suppression by budesonide (difference -102 nmol/l; 95% CI -226, -52; P = 0.0028). Glucocorticosteroid side effects such as moon face and acne occurred significantly less frequently in the budesonide group. Remission (Crohn's Disease Activity Index < or = 150) was seen at 8 weeks in 12/22 (55%) patients treated with budesonide and in 17/24 (71%) patients receiving prednisolone (difference -16%; 95% CI -45,13; P = 0.25). CONCLUSIONS: Significantly fewer side effects and less adrenal suppression were observed in the children receiving budesonide. Remission rates were not significantly different in the two groups. However, there was a trend for prednisolone to be more effective for inducing remission.     

Effect of Budesonide Enema on Remission and Relapse Rate in Distal Ulcerative Colitis and Proctitis

Background: Glucocorticosteroid enemas are equally effective as 5-ASA enemas in the treatment of active distal ulcerative colitis (UC). With the introduction of budesonide, the risk of systemic side effects may be reduced. We investigated whether budesonide enema, 2 mg/100 ml, administered twice daily (b.i.d.) could increase the remission rate in comparison with the once daily (o.d.) standard regimen. Furthermore, we evaluated whether 2 mg budesonide enema, given twice weekly, could have a relapse preventing effect. Methods: 149 patients with active distal UC were treated in a controlled, double-blind multicentre study with two parallel groups: placebo enema in the morning and budesonide enema in the evening (i.e. 2 mg/day) or budesonide enema b.i.d. (i.e. 4 mg/day) until remission (absence of clinical symptoms and endoscopic healing) or at most 8 weeks. Patients in remission were randomized to either budesonide enema or placebo enema twice weekly for 24 weeks or until relapse. Results: The remission rates at 4 weeks were 33% for o.d. and 41% for b.i.d. regimens (NS) and correspondingly 51% and 54% at 8 weeks (NS). The b.i.d. group had an increased frequency of impaired adrenal function, 32% versus 4.8% ( P = 0.001). The relapse rates during maintenance treatment with budesonide enema and placebo were 15% versus 24% after 8 weeks, 31% versus 27% after 16 weeks and 41% versus 51% after 24 weeks (NS). Conclusion: Budesonide enema 2 mg o.d. appears to be the optimal dosage in active distal UC. We could not show that budesonide enema twice weekly is sufficient to maintain remission.     

Faecal Elastase-1: Lyophilization of Stool Samples Prevents False Low Results in Diarrhoea

Background: In patients with diarrhoea, faecal elastase-1 is used to detect exocrine pancreatic insufficiency. Diarrhoea is defined as &gt;85% stool water content. Methods: We analysed elastase-1 in 519 stool samples from 310 patients unprocessed as well as after lyophilization in a standard laboratory lyophilizator. Stool water content was calculated by weight difference before and after lyophilization. Results:     

Oral budesonide versus prednisolone in patients with active extensive and left-sided ulcerative colitis

BACKGROUND & AIMS: Systemic glucocorticosteroids (GCSs) have proven efficacy in active ulcerative colitis but cause undesired systemic side effects. Therefore, new GCSs with high topical activity and a high rate of metabolism may be of clinical value in this condition. The aim of this study was to explore the efficacy and safety of the topically acting GCS budesonide in an oral controlled-release formulation in extensive or left-sided, mild to moderately active ulcerative colitis. METHODS: A 9-week, randomized, double-blind, controlled trial was performed, and treatments with 10 mg budesonide or 40 mg prednisolone daily, both gradually tapered, were compared. Endoscopic improvement and effect on endogenous plasma cortisol were assessed. RESULTS: Thirty- four patients were administered budesonide, and 38 patients were administered prednisolone. Mean endoscopic scores improved significantly in both groups but without difference between the groups. Five patients in the budesonide group and 7 patients in the prednisolone group deteriorated and were withdrawn from the study. Morning plasma cortisol levels were suppressed in the prednisolone group (entry, 449 nmol/L; 2 weeks, 116 nmol/L; 4 weeks, 195 nmol/L) but were unchanged in the budesonide group. CONCLUSIONS: The GCS budesonide administered in an oral controlled-release formulation seems to give an overall treatment result in active ulcerative colitis approaching that of prednisolone but without suppression of plasma cortisol levels. This concept merits further evaluation. (Gastroenterology 1996 Jun;110(6):1713-8)     

Colitis microscópica: avances para una mejor identificación en los pacientes con diarrea crónica

Microscopic colitis is a generic term that includes 2 main forms, collagenous colitis and lymphocytic colitis, and describes a form of inflammatory bowel disease with a chronic and relapsing course. The incidence of microscopic colitis is between 2 and 8 times higher in women than in men, although age, more than sex, increases the risk of collagenous colitis (odds ratio [OR] 8.3 for age ≥ 65 vs. < 65 and OR 2.8 for women). The main symptom is chronic non-bloody watery diarrhoea. Other common symptoms include abdominal pain (50%-70%), with the result that many patients with microscopic colitis meet criteria for irritable bowel syndrome. Colonoscopy with multiple colonic biopsies is currently recommended, as histological changes are the main characteristic feature. The colonic mucosa is macroscopically normal, although certain minimal endoscopic abnormalities have been described.     

What Concerns Subjects with Inflammatory Bowel Disease and an Ileostomy?

Background: The greatest concern of patients with inflammatory bowel disease (IBD) is of having an ileostomy. The aim of this study was to describe worries and concerns in subjects with IBD and an ileostomy, and aspects of quality of life and coping strategies. Methods: 21 subjects with an ileostomy were included, mean age 51, range 36-65 (F/M &#114 = &#114 12/9), Crohn disease (CD) n &#114 = &#114 14, ulcerative colitis (UC) n &#114 = &#114 6 and indeterminate colitis (IDC) n &#114 = &#114 1. Worries and concerns were assessed using the rating form of IBD patient concerns (RFIPC). Health-related quality of life (HRQOL) was assessed using Short Form 36 (SF-36) and compared with a matched group for age and gender from the general population. Subjects' definition of quality of life, as well as perceived quality of life on a visual analogue scale, was evaluated. Coping strategies were investigated using the Jalowiec coping scale (JCS 40). Results: Greatest concerns were related to intimacy, access to quality medical care, energy level, loss of sexual drive, producing unpleasant odours, being a burden, ability to perform sexually, attractiveness and feelings about the body. Vitality was significantly reduced compared to controls. Subjects' definition of good quality of life mainly concerned social dimensions of life and health. Low values on perceived quality of life indicated greater concerns. Confrontational coping style was most frequently used. Conclusion: The greatest concern for subjects with an ileostomy was intimacy. Vitality was reduced compared to controls. Integrating items of concern into counselling may result in greater coping ability and improved quality of life.
