BACKGROUND: Aminosalicylates are the mainstay of therapy to prevent relapse of quiescent ulcerative colitis. The rationale for using probiotics is based on the evidence implicating intestinal bacteria in the pathogenesis of this disorder. AIM: To evaluate the efficacy of Lactobacillus GG alone or in combination with mesalazine vs. mesalazine as maintenance treatment in ulcerative colitis. PATIENTS AND METHODS: 187 ulcerative colitis patients with quiescent disease were randomized to receive Lactobacillus GG 18 x 10(9) viable bacteria/day (65 patients), mesalazine 2400 mg/day (60 patients) or Lactobacillus GG + mesalazine (62 patients). Disease activity index, endoscopic and histological scores were determined at 0, 6 and 12 months and in case of relapse. The primary end point was to evaluate sustained remission. RESULTS: Overall analysis showed no difference in relapse rate at 6 (P = 0.44) and 12 months (P = 0.77) among the three treatment groups. However, the treatment with Lactobacillus GG seems to be more effective than standard treatment with mesalazine in prolonging the relapse-free time (P < 0.05). CONCLUSIONS: Lactobacillus GG seems to be effective and safe for maintaining remission in patients with ulcerative colitis, and it could represent a good therapeutic option for preventing relapse in this group of patients. 相似文献

Nine of 26 French tourists developed malaria after a 2-week stay under field conditions in a highly endemic place in Burkina Faso. A study of their preventive antimalarial measures identified a strong association of malaria attack with absence or inadequacy of chemoprophylaxis but not with mechanic measures. 相似文献

Probiotics are widely used as functional foods which have been advocated for the maintenance of gastrointestinal microflora equilibrium and treatment of gastrointestinal disorders. However, studying the role of probiotics in peptic ulcer disease is limited. The aim of the present study is to investigate the effect of a probiotic strain Lactobacillus rhamnosus GG on gastric ulcer and to elucidate the mechanisms involved. Gastric kissing ulcers were induced in rats by acetic acid (60% v/v). L. rhamnosus GG was given intragastrically at 10(8) cfu/day or 10(9) cfu/day for three consecutive days after ulcer induction. L. rhamnosus GG successfully colonized in the gastric mucosa especially at the ulcer margin. It also significantly and dose-dependently reduced gastric ulcer area. Cell apoptosis to cell proliferation ratio was strongly decreased and accompanied by significant up-regulation of ornithine decarboxylase (ODC) and B-cell lymphoma 2 (Bcl-2) protein expression at the ulcer margin. Angiogenesis was also significantly stimulated together with the induction of vascular endothelial growth factor (VEGF) expression. Furthermore, L. rhamnosus GG up-regulated the phosphorylation level of epidermal growth factor receptor (EGF receptor) without altering the total EGF receptor expression. These findings suggested that L. rhamnosus GG enhanced gastric ulcer healing via the attenuation of cell apoptosis to cell proliferation ratio and increase in angiogenesis. Regulators of these processes such as ODC, Bcl-2, VEGF and EGF receptor are likely to be involved in the healing action of L. rhamnosus GG for gastric ulcer. 相似文献

AIM: To review evidence for the effectiveness of Lactobacillus GG (LGG) in treating acute infectious diarrhoea in children. METHODS: The following electronic databases were searched through August 2006 for studies relevant to acute infectious diarrhoea and LGG: MEDLINE, EMBASE, CINAHL and The Cochrane Library; additional references were obtained from reviewed articles. Only randomized-controlled trials (RCTs) were included. RESULTS: Eight RCTs (988 participants) met the inclusion criteria. Compared with controls, LGG had no effect on the total stool volume (two RCTs, n = 303). However, LGG was associated with a significant reduction in diarrhoea duration (seven RCTs, 876 infants, weighted mean difference, WMD -1.1 days (95% confidence interval, CI -1.9 to -0.3), particularly of rotavirus etiology (WMD -2.1 days, 95% CI -3.6 to -0.6), risk of diarrhoea >7 days (one RCT, n = 287, relative risk 0.25, 95% CI 0.09-0.75) and duration of hospitalization (three RCTs, n = 535, WMD -0.58, 95% CI -0.8 to -0.4; significance was lost in the random effect model). There was no reduction in the number of stools at any time interval. CONCLUSIONS: The use of LGG is associated with moderate clinical benefits in the treatment of acute diarrhoea in children. These findings should be interpreted with caution due to the important methodological limitations and heterogeneity of most of the studies. 相似文献

BACKGROUND: Preliminary trials of probiotics in preventing recurrent chronic pouchitis have been encouraging. AIM: To investigate the efficacy of Lactobacillus GG supplementation as primary therapy for ileal pouch inflammation, and its effect on the microbial flora. METHODS: Twenty patients, with a previous history of pouchitis and endoscopic inflammation, were recruited for a prospective, randomized, double-blind, placebo-controlled trial of Lactobacillus GG supplementation (10 LGG, 10 placebo) in two gelatine capsules [(0.5-1) x 10(10) colony-forming units/capsule] b.d. for 3 months. Quantitative bacterial culture of fresh faecal samples and biopsies taken from the pouch and afferent limb was performed before and after supplementation. RESULTS: Lactobacillus GG supplementation changed the pouch intestinal flora by increasing the ratio of total faecal lactobacilli to total faecal anaerobes (P = 0.03) and enhancing the frequency of lactobacilli-positive cultures in the pouch and afferent limb mucosal biopsy samples. However, only 40% of patients were colonized with Lactobacillus GG. No differences were observed between the groups with regard to the mean pouchitis disease activity index or the total anaerobes or aerobes of faecal or tissue biopsy samples. CONCLUSIONS: A single-strain probiotic bacterium supplement of Lactobacillus GG changed the pouch intestinal bacterial flora, but was ineffective as primary therapy for a clinical or endoscopic response. More clinical trials are needed to evaluate the right placement and dosage of probiotics within a treatment regimen for pouchitis. 相似文献

Background A lack of reliable treatments for abdominal pain‐related functional gastrointestinal disorders prompts interest in new therapies. Aim To evaluate systematically the effect of Lactobacillus rhamnosus GG (LGG) for treating abdominal pain‐related functional gastrointestinal disorders in children. Methods MEDLINE, EMBASE, CINAHL, the Cochrane Library, trial registries and proceedings of major meetings were searched for randomised controlled trials (RCTs) evaluating LGG supplementation in children with abdominal pain‐related functional gastrointestinal disorders based on the Rome II or Rome III criteria. Risk of bias was assessed for generation of the allocation sequence, allocation concealment, blinding and follow‐up. Results Compared with placebo, LGG supplementation was associated with a significantly higher rate of treatment responders (defined as no pain or a decrease in pain intensity) in the overall population with abdominal pain‐related functional gastrointestinal disorders (three RCTs, n = 290; risk ratio, RR 1.31, 95% CI 1.08–1.59, number needed to treat, NNT 7, 95% CI 4–22) and in the irritable bowel syndrome (IBS) subgroup (three RCTs, n = 167; RR 1.70, 95% CI 1.27–2.27, NNT 4, 95% CI 3–8). However, no difference was found in the rate of treatment responders between children with functional abdominal pain or functional dyspepsia who received placebo or LGG. The intensity of pain was significantly reduced in the overall study population and in the IBS subgroup. The frequency of pain was significantly reduced in the IBS subgroup only. Conclusion The use of Lactobacillus rhamnosus GG moderately increases treatment success in children with abdominal pain‐related functional gastrointestinal disorders, particularly among children with IBS. 相似文献

BACKGROUND: Functional abdominal pain disorders (FAPD) are common in school-aged children; however, there is no reliable treatment. AIM: To determine the efficacy of Lactobacillus rhamnosus GG (LGG) for treating FAPD in children. METHODS: A total of 104 children who fulfilled the Rome II criteria for functional dyspepsia (FD), or irritable bowel syndrome (IBS), or functional abdominal pain (FAP) were enrolled in a double-blind, randomized controlled trial in which they received LGG (n = 52), or placebo (n = 52) for 4 weeks. RESULTS: For the overall study population, those in the LGG group were more likely to have treatment success (no pain) than those in the placebo group (25% vs. 9.6%, relative benefit (RB) 2.6, 95% confidence interval (CI): 1.05-6.6, number needed to treat (NNT) 7, 95% CI: 4-123). For children with IBS (n = 37), those in the LGG group were more likely to have treatment success than those in the placebo group (33% vs. 5%, RB 6.3, 95% CI: 1.2-38, NNT 4, 95% CI: 2-36) and reduced frequency of pain (P = 0.02), but not pain severity (P = 0.10). For the FD group (n = 20) and FAP group (n = 47), no differences were found. CONCLUSION: The LGG appears to moderately increase treatment success, particularly among children with IBS. 相似文献

Summary
Background In children, healthcare‐associated diarrhoea, in particular, due to rotavirus, may prolong the hospital stay and increase medical costs, prompting interest in effective, low‐cost, preventive strategies. Aim To review systematically data on the efficacy of administering Lactobacillus rhamnosus GG (LGG) for the prevention of healthcare‐associated diarrhoea. Methods MEDLINE, EMBASE, Health Source: Nursing/Academic Edition, the Cochrane Library, trial registries and proceedings of major meetings were systematically searched for randomised controlled trials (RCTs) performed in children aged 1 month to 18 years that compared administration of LGG with placebo or no intervention. Two reviewers assessed studies for inclusion and risk of bias and extracted the data. Outcome measures included the incidences of healthcare‐associated diarrhoea and rotavirus gastroenteritis. If appropriate, meta‐analyses were carried out using the fixed effects model. Results Three RCTs involving 1092 children were included. Compared with placebo, LGG administration for the duration of hospital stay was associated with significantly lower rates of diarrhoea (two RCTs, n = 823, relative risk, RR 0.37, 95% confidence interval, CI 0.23–0.59) and symptomatic rotavirus gastroenteritis (three RCTs, n = 1043, RR 0.49, 95% CI 0.28–0.86). There was no significant difference between the LGG and the control groups in the incidence of asymptomatic rotavirus infection, duration of hospitalisation or duration of diarrhoea. LGG was well tolerated, and no harms were reported in any of the trials. Conclusion In hospitalised children, the administration of Lactobacillus rhamnosus GG compared with placebo has the potential to reduce the overall incidence of healthcare‐associated diarrhoea, including rotavirus gastroenteritis. 相似文献12.

BACKGROUND: One-week triple therapy is currently considered the golden standard against Helicobacter pylori. However, gastrointestinal side-effects are among the major pitfalls in such regimens. Probiotic supplementation might help to prevent or reduce such drug-related manifestations. AIM: To determine whether adding the probiotic Lactobacillus GG to an anti-H. pylori regimen could help to prevent or minimize the gastrointestinal side-effects burden. METHODS: Sixty healthy asymptomatic subjects screened positive for H. pylori infection were randomized to 1 week rabeprazole (20 mg b.d.), clarithromycin (500 mg b.d.), tinidazole (500 b.d.) and the probiotic Lactobacillus GG for 14 days or to the same regimen with a placebo preparation. Patients completed validated questionnaires during the week of treatment and during the following 3 weeks, to determine the type and severity of side-effects and an overall judgement of tolerability. RESULTS: Diarrhoea, nausea and taste disturbance were significantly reduced in the Lactobacillus GG supplemented group (relative risk=0.1, 95% CI: 0.1-0.9; relative risk=0.3, 95% CI: 0.1-0.9; relative risk=0.5, 95% CI: 0.2-0.9, respectively). An overall assessment of treatment tolerability showed a significant difference in favour of the Lactobacillus GG supplemented group (P=0.04). CONCLUSIONS: Lactobacillus GG supplementation showed a positive impact on H. pylori therapy-related side-effects and on overall treatment tolerability. 相似文献
