    Survey of gastroenterologists' awareness and implementation of AGA guidelines on osteoporosis in inflammatory bowel disease patients: Are the guidelines being used and what are the barriers to their use?,

    INFLAMMATORY BOWEL DISEASES, Issue 7 2009
    Julianne H. Wagnon MSN
    Abstract Background: The American Gastroenterology Association (AGA) published guidelines to assist clinicians in the evaluation and management of osteoporosis in inflammatory bowel disease (IBD) patients. Two studies suggest that when clinicians utilized the guidelines, the majority of their IBD patients were appropriately screened and treated for metabolic bone disease. The aim was to study whether physicians who say they use the AGA Guidelines are, in fact, following the recommendations, and to assess the barriers preventing the use of the guidelines in the management of osteoporosis in their IBD patients. Methods: In all, 1000 physicians were selected from the AGA membership list and mailed a survey inquiring into awareness and implementation of the guidelines on osteoporosis in IBD patients. The barriers to implementation of the guidelines were also assessed. The sum of 21 self-reported clinical practices (absence = 0, presence = 1) was used to evaluate adherence to the guidelines. A value of 0 implied no adherence while a score of 21 meant complete adherence. Results: Of 304 responders, 27 fellows, 8 retirees, and 11 incomplete responses were not included in the analysis; thus, 258 respondents were the subject of this analysis. Slightly less than half of the responders used the guidelines in decision-making (126, 49%) or in the management (110, 42%) of their IBD patients. Using the scoring system described above, clinicians self-reporting use of the guidelines had a significantly higher clinical practice score than those who did not use the guidelines (Wilcoxon rank sum test; P < 0.0001). Only 18% (12 of 68) of clinicians whose practice was comprised of ,25% IBD patients used the guidelines compared to 60% (113/187) physicians who cared for more IBD patients (chi-square test; P < 0.0001). Physicians who saw more IBD patients (>25%) were also more likely (97/187 = 52%) to assess and treat osteoporosis in their IBD patients. Conversely, only 16% (11/68) of physicians who saw ,25% IBD patients treated osteoporosis (chi-square test; P < 0.0001). The main reason physicians (n = 115) gave for not utilizing the guidelines was because they felt that IBD should be the focus of the visit (48, 42%); 34 (30%) reported that osteoporosis should be managed by another physician. Other barriers cited were lack of time (13, 11%), cost (10, 9%), and lack of knowledge (10, 9%). Conclusions: Most of the responding physicians do not utilize the AGA Guidelines on metabolic bone disease in IBD patients. The physicians who self-reported utilizing the guidelines were actually adhering to the recommendations. Further education regarding the impact of metabolic bone disease in IBD patients and the importance of the guidelines is needed, particularly as it addresses the barriers set forth above.

    Inflammatory bowel disease patients who leave hospital against medical advice: Predictors and temporal trends

    INFLAMMATORY BOWEL DISEASES, Issue 6 2009
    Gilaad G. Kaplan MD
    Abstract Background: Leaving hospital against medical advice (AMA) may have consequences with respect to health-related outcomes; however, inflammatory bowel disease (IBD) patients have been inadequately studied. Thus, we determined the prevalence of self-discharge, assessed predictors of AMA status, and evaluated time trends. Methods: We analyzed the 1995,2005 Nationwide Inpatient Sample (NIS) to identify 93,678 discharges with a primary diagnosis of IBD admitted to the hospital emergently and did not undergo surgery. We described the proportion of IBD patients who left AMA. Predictors of AMA status were evaluated using a multivariate logistic regression model and temporal trend analyses were performed with Poisson regression models. Results: Between 1995 and 2005, 1.31% of IBD patients left hospitals AMA. Crohn's disease (CD) patients were more likely to leave AMA (adjusted odds ratio [aOR], 1.53; 95% confidence intervals [CI]: 1.30,1.79). Characteristics associated with leaving AMA included: ages 18,34 (aOR, 7.77, 95% CI: 4.34,13.89); male (aOR, 1.75; 95% CI: 1.55,1.99); Medicaid (aOR, 4.55; 95% CI: 3.81,5.43) compared to private insurance; African Americans (aOR, 1.34; 95% CI: 1.09,1.64) compared to white; substance abuse (aOR, 2.75; 95% CI: 2.14,3.54); and psychosis (aOR, 1.55; 95% CI: 1.13,2.14). The incidence rates of self-discharge for CD patients were stable (P > 0.05) between 1995 and 1999, while they significantly (P < 0.0001) increased after 1999. In contrast, AMA rates for UC patients remained stable during the study period. Conclusions: Approximately 1 in 76 IBD patients admitted emergently for medical management leave the hospital AMA. These were primarily disenfranchised patients who may lack adequate outpatient follow-up. (Inflamm Bowel Dis 2009) [source]


    Further experience with the use of 6-thioguanine in patients with Crohn's disease

    INFLAMMATORY BOWEL DISEASES, Issue 10 2008
    Azhar Ansari MD
    Abstract Background: 6-Thioguanine (6-TG) is efficacious in patients with Crohn's Disease (CD) failing conventional immunosuppression but there are reports of hepatotoxicity. We report our experience of the safety and efficacy of 6-TG in a series of patients with CD. Methods: A retrospective study of patients with CD who failed thiopurines ± methotrexate between 2001 and 2006 was performed. Indications for 6-TG were; active disease, to allow infliximab withdrawal, steroid sparing, or fistula closure. Patients underwent regular review and those treated longer than 1 year were advised to have liver magnetic resonance imaging (MRI) and liver biopsy. Results: All 30 patients treated with 6-TG during the period were included. The median dose and duration of 6-TG was 40 mg daily and 21.5 months, respectively. Initial clinical response was achieved in 18/30 (60%). Eleven of 29 (38%) (1 unrelated death) remained in remission at a median 44 months follow-up. Seven of 30 (23%) discontinued 6-TG due to adverse effects; 7/30 (23%) patients developed abnormal liver function tests (LFTs) during treatment, mostly transient and mild. One patient developed a portal hypertensive syndrome resolving on cessation of 6-TG. Of 11 liver biopsies, none showed nodular regenerative hyperplasia (NRH). The median red blood cell 6-thioguanine nucleotide (6-TGN) level was 807 pmol/108. Conclusions: 6-TG has good clinical efficacy for third-line immunosuppression in CD but hepatotoxicity remains a concern. However, previous reports of NRH in 6-TG-treated inflammatory bowel disease patients have not been substantiated by this cohort. (Inflamm Bowel Dis 2008) [source]


    Nationwide prevalence and prognostic significance of clinically diagnosable protein-calorie malnutrition in hospitalized inflammatory bowel disease patients

    INFLAMMATORY BOWEL DISEASES, Issue 8 2008
    Geoffrey C. Nguyen MD
    Abstract Background Inflammatory bowel disease (IBD) patients are at increased risk of protein-calorie malnutrition. We sought to determine the prevalence of clinically diagnosable malnutrition among those hospitalized for IBD throughout the United States and whether this malnutrition influenced health outcomes. Methods We queried the Nationwide Inpatient Sample between 1998 and 2004 to identify admissions for Crohn's disease (CD) or ulcerative colitis (UC) and a representative sample of non-IBD discharges. We assessed the prevalence and predictors of malnutrition and its association with in-hospital mortality and resource utilization. Results The prevalence of malnutrition was greater in CD and UC patients than in non-IBD patients (6.1% and 7.2% versus 1.8%, P < 0.0001). The adjusted odds ratio for malnutrition among IBD admissions compared with non-IBD admissions was 5.57 [95% confidence interval (CI): 5.29,5.86]. More IBD discharges than non-IBD discharges with malnutrition received parenteral nutrition (26% versus 6%, P < 0.0001). There was increased likelihood of malnutrition among those with fistulizing CD (OR 1.65; 95% CI: 1.50,1.82) and among those who had undergone bowel resection (OR 1.37; 95% CI: 1.27,1.48). Malnutrition was associated with increased in-hospital mortality 3.49 (95% CI: 2.89,4.23), length of stay (11.9 days versus 5.8 days, P < 0.00001), and total charges ($45,188 versus $20,295, P < 0.0001). Conclusions Clinically apparent malnutrition is more frequent among IBD admissions than among non-IBD admissions. Its association with greater mortality and resource utilization may reflect more severe underlying disease that can lead to both malnutrition and worse outcomes. Nonetheless, diagnosable malnutrition may serve as a clinical marker of poor IBD prognosis in hospitalized patients. (Inflamm Bowel Dis 2008) [source]


    Autoimmune disease concomitance among inflammatory bowel disease patients in the United States, 2001-2002

    INFLAMMATORY BOWEL DISEASES, Issue 6 2008
    Russell Cohen MD
    Abstract Background: Recent studies suggest that inflammatory bowel disease (IBD) may share an underlying pathogenesis with other autoimmune diseases. Methods: Two United States data sets with patient-level medical and drug claims were used to explore the occurrence of autoimmune diseases in patients with IBD, particularly Crohn's disease (CD) and ulcerative colitis (UC), with that in controls. From 2001 to 2002 IBD patients were identified using International Classification of Diseases, 9th revision, diagnosis codes in the IMS Health Integrated Administration Claims Database and the Market Scan Commercial Claims and Encounters Database. Controls were selected by matching on sex, age, Census Bureau region, and length of previous medical insurance coverage. Odds ratios (ORs) evaluated the risk relationship between IBD patients and controls within an estimated Mantel-Haenszel 95% confidence interval. Sensitivity analysis tested the case identification method used to select IBD patients. Results: The risk for ankylosing spondylitis (AS) was substantially increased across both data sets: OR (95% confidence interval [CI]) of 7.8 (5.6,10.8) in IMS Health and 5.8 (3.9,8.6) in MarketScan. The risk for rheumatoid arthritis (RA) was 2.7 (2.4,3.0) and 2.1 (1.8,2.3), respectively; for multiple sclerosis (MS); the ORs were 1.5 (1.2,1.9) and 1.6 (1.2,2.1), respectively. There was no increased risk for type 1 diabetes mellitus, and the results for psoriatic arthritis (PsA) were inconsistent. The sensitivity analysis supported these findings. Conclusions: A much higher risk for RA, AS, PsA, and MS was observed in IBD patients compared with controls. Prospective epidemiologic studies are needed to confirm these findings and explore the pathogenic mechanism of this relationship. (Inflamm Bowel Dis 2008) [source]

    Assessing health-related quality of life in patients with inflammatory bowel disease in Zhejiang, China

    JOURNAL OF CLINICAL NURSING, Issue 1-2 2010
    Yunxian Zhou
    Aims., The aim of this study was to assess health-related quality of life in patients with inflammatory bowel disease in Zhejiang, Mainland China. Background., The incidence of inflammatory bowel disease in China is believed to be low but has been increasing in the past decade. The quality of life of Chinese patients with inflammatory bowel disease is unknown. Design., A cross-sectional study. Methods., The study was conducted in 92 patients with inflammatory bowel disease in Zhejiang, China, 52 with ulcerative colitis and 40 with Crohn's disease. Health-related quality of life was measured by the Chinese version of the Inflammatory Bowel Disease Questionnaire and Short Form-36, respectively. Disease activity was assessed by the Walmsley and Harvey,Bradshaw simple indices for ulcerative colitis and Crohn's disease, respectively. Demographic and clinical variables were also recorded. Short Form-36 data from the study sample were compared with a reference population of 1688 Chinese people residing in Hangzhou, Zhejiang, China. Results., No significant health-related quality of life differences were found between patients with ulcerative colitis and Crohn's disease (p > 0·05). Pooled data showed that inflammatory bowel disease patients with active disease had significantly lower scores for all eight dimensions of Short Form-36 compared to those in remission (p < 0·01); those with active disease scored significantly lower than population norms in all dimensions of Short Form-36 except mental health (p < 0·05); whereas those in remission scored significantly lower than population norms in role physical (p < 0·01) and general health dimensions (p < 0·05). The regression analyses identified only disease activity index and employment status to explain variations in health-related quality of life (p < 0·01). Conclusions., Inflammatory bowel disease similarly impairs health-related quality of life in patients with both ulcerative colitis and Crohn's disease. Relevance to clinical practice., The results suggest that any interventions that produce a stable clinical remission, whether medical or surgical, allowing patients to return to their usual work position can decrease the disease impact on their daily lives.

    Mercaptopurine rescue after azathioprine-induced liver injury in inflammatory bowel disease

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2010
    F. BERMEJO
    Summary Background, Azathioprine (AZA) liver toxicity arises in approximately 3% of inflammatory bowel disease patients and may result in treatment discontinuation. Aim, To describe the tolerance to mercaptopurine (MP) in patients with previous AZA-related liver injury. Methods, Retrospective description of 31 patients (14 Crohn's, 17 ulcerative colitis), in which AZA therapy was interrupted because of liver injury, with MP started as alternative therapy. Results, Mean AZA dose was 2.2 ± 0.4 mg·kg/day. Median (interquartile range) of AZA exposure when liver injury was detected was 2 months (1,5.2). The type of AZA-related injury was cytolitic in 32%, cholestatic in 39% and mixed in 29%. After a median of 2.5 months (0.7,5.2), the therapy was switched to MP at a mean dose of 1.3 ± 0.2 mg·kg/day. Median of follow-up of MP therapy was 32 months (8,54). In 87.1% of patients (95%CI: 70,96%), MP was tolerated without further liver injury; of these, 77.4% tolerated full MP doses and 9.7% tolerated lower doses. In a further cohort of 12.9% of patients, (95%CI: 3,29%), liver injury reappeared (two cholestasis, two mixed), 1,3 months after the onset of MP exposure. Conclusion, The administration of MP is a good alternative in patients with AZA-related liver injury, before thiopurines are definitely discarded. [source]


    Withdrawal of corticosteroids in inflammatory bowel disease patients after dependency periods ranging from 2 to 45 years: a proposed method

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009
    S. J. MURPHY
    Summary Background, Even in the biologic era, corticosteroid dependency in IBD patients is common and causes a lot of morbidity, but methods of withdrawal are not well described. Aim, To assess the effectiveness of a corticosteroid withdrawal method. Methods, Twelve patients (10 men, 2 women; 6 ulcerative colitis, 6 Crohn's disease), median age 53.5 years (range 29,75) were included. IBD patients with quiescent disease refractory to conventional weaning were transitioned to oral dexamethasone, educated about symptoms of the corticosteroid withdrawal syndrome (CWS) and weaned under the supervision of an endocrinologist. When patients failed to wean despite a slow weaning pace and their IBD remaining quiescent, low dose synthetic ACTH stimulation testing was performed to assess for adrenal insufficiency. Multivariate analysis was performed to assess predictors of a slow wean. Results, Median durations for disease and corticosteroid dependency were 21 (range 3,45) and 14 (range 2,45) years respectively. Ten patients (83%) were successfully weaned after a median follow-up from final wean of 38 months (range 5,73). Disease flares occurred in two patients, CWS in five and ACTH testing was performed in 10. Multivariate analysis showed that longer duration of corticosteroid use appeared to be associated with a slower wean (P = 0.056). Conclusions, Corticosteroid withdrawal using this protocol had a high success rate and durable effect and was effective in patients with long-standing (up to 45 years) dependency. As symptoms of CWS mimic symptoms of IBD disease flares, gastroenterologists may have difficulty distinguishing them, which may be a contributory factor to the frequency of corticosteroid dependency in IBD patients.

    Incidence of benign upper respiratory tract infections, HSV and HPV cutaneous infections in inflammatory bowel disease patients treated with azathioprine

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 10 2009
    P. SEKSIK
    Summary Background, There are few data on the incidence of benign infections (upper respiratory tract infections, herpes lesions and viral warts) during exposure to azathioprine. Aims, To determine the incidence of benign infections in IBD out-patients receiving azathioprine (AZA+) and to look at the influence of leucocyte counts in the onset of these events. Methods, A total of 230 patients were included in a prospective cohort and observed during 207 patient-years. Episodes of benign infections were collected and incidences of benign infections were compared between the AZA+ group and patients without AZA (AZA,). Results, The incidence of upper respiratory tract infections in the cohort was 2.1 ± 2.2 per observation-year. There was no difference between the AZA+ (n = 169) and AZA, (n = 61) groups (2.2 ± 2.3 vs. 2.1 ± 2.1, P = 0.77). The incidence of herpes flares was significantly increased in the AZA+ group compared to the AZA, group (1.0 ± 2.6 vs. 0.2 ± 0.8 per year, P = 0.04). Similarly, there were significantly more patients with appearance or worsening viral warts in the AZA+ group (17.2% (AZA+) vs. 3.3% (AZA,), P = 0.004). Conclusion, This study suggests that the incidence of herpes flares and the appearance or worsening of viral warts are increased in IBD patients receiving AZA. [source]


    Early clinical experience with adalimumab in treatment of inflammatory bowel disease with infliximab-treated and naïve patients

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2009
    A. SWAMINATH
    Summary Background, Adalimumab, at an induction dose of 160/80 mg followed by 40 mg every other week is approved for treatment of refractory Crohn's disease (CD) and for patients with loss of response to infliximab. Aim, To evaluate the indications for adalimumab, the proportion of inflammatory bowel disease patients who require dose escalation and to identify whether this strategy is effective in inducing or maintaining remission. Methods, Patients prescribed adalimumab for CD were identified and included for analysis, if they had follow-up of at least 6 weeks. Adalimumab dose was escalated if patients had return of symptoms prior to next dose. Clinical judgment was used to determine severity of disease. A second GI physician confirmed disease severity as determined by the first physician. Results, A total of 48 out of 60 patients met inclusion criteria. Adalimumab was used to treat CD in 47/48 (98%) and ulcerative colitis in one (2%). Most patients had moderate 30/48 (63%) or severe 17/48 (35%) disease. Prior infliximab exposure was present in 42/48 (88%). Adalimumab dose escalation occurred in 14/48 (29%) within an average time of 2.2 months (s.d. 1.5 months). A majority of patients who required dose escalation, nine of 14 (64%) did not improve clinically. Steroids could be discontinued in three of 16 (18.8%). Clinical improvement was noted in 21/48 (43.8%) and one of 48 (2%) patients achieved clinical remission. Adverse drug reactions necessitated drug discontinuation in four of 48 (8%) of patients. Conclusions, This retrospective review from a single academic medical centre suggests that a minority of patients, who cannot be maintained on 40 mg every other week, of adalimumab benefit from an increased dose. This suggests the need for a treatment with an alternative mode of action in anti-TNF failures. [source]


    Allopurinol safely and effectively optimizes tioguanine metabolites in inflammatory bowel disease patients not responding to azathioprine and mercaptopurine

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2005
    M. P. SPARROW
    Summary Background :,Many non-responders to azathioprine or mercaptopurine (6-mercaptopurine) have high normal thiopurine methyltransferase activity and preferentially metabolize mercaptopurine to produce 6-methylmercaptopurine instead of the active 6-tioguanine (6-tioguanine) metabolites. Aim :,To describe the use of allopurinol in mercaptopurine/azathioprine non-responders to deliberately shunt metabolism of mercaptopurine towards 6-tioguanine. Methods :,Fifteen thiopurine non-responders whose metabolites demonstrated preferential metabolism towards 6-methylmercaptopurine are described. Subjects were commenced on allopurinol 100 mg po daily and mercaptopurine/azathioprine was reduced to 25,50% of the original dose. Patients were followed clinically and with serial 6-tioguanine and 6-methylmercaptopurine metabolite measurements. Results :,After initiating allopurinol, 6-tioguanine levels increased from a mean of 185.73 ± 17.7 to 385.4 ± 41.5 pmol/8 × 108 red blood cells (P < 0.001), while 6-methylmercaptopurine decreased from a mean of 10 380 ± 1245 to 1732 ± 502 pmol/8 × 108 RBCs (P < 0.001). Allopurinol led to a decrease in white blood cell from a mean of 8.28 ± 0.95 to 6.1 ± 0.82 × 108/L (P = 0.01). Conclusions :,The addition of allopurinol to thiopurine non-responders with preferential shunting to 6-methylmercaptopurine metabolites appears to be an effective means to shift metabolism towards 6-tioguanine.

    Review article: practical management of inflammatory bowel disease patients taking immunomodulators

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2005
    C. A. SIEGEL
    Summary Azathioprine, mercaptopurine, methotrexate, ciclosporin and tacrolimus all have their respective niches in the treatment of inflammatory bowel disease. These immunomodulators are potent and effective medications; however, they potentially have serious toxicity. To maximize benefit and minimize risk, clinicians must understand the mechanism of action, appropriate indications, range of toxicity and proper dosing of these medications. Furthermore, once initiating therapy, patients need to be monitored appropriately for evidence of efficacy and toxicity. This review includes the rationale behind recommendations for the management and monitoring of patients using immunomodulators. For the purine antagonists , azathioprine and mercaptopurine , the evidence for utility of thiopurine methyltransferase testing and mercaptopurine metabolite monitoring is addressed. The roles of liver biopsy and screening for methylenetetrahydrofolate reductase mutations in patients taking methotrexate are reviewed. With appropriate monitoring, the calcineurin inhibitors , ciclosporin and tacrolimus , can be used safely and effectively. Immunomodulators are important agents for the treatment of Crohn's disease and ulcerative colitis, and prescribing clinicians should be comfortable recognizing both their value and their limitations.

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

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2001
    K. R. Herrlinger
    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 (,1-microglobulin-,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 ,1-MG. The amount of ,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. [source]


    Anti-inflammatory effects of probiotic yogurt in inflammatory bowel disease patients

    CLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 3 2007
    M. Lorea Baroja
    Summary Our aim was to assess anti-inflammatory effects on the peripheral blood of subjects with inflammatory bowel disease (IBD) who consumed probiotic yogurt for 1 month. We studied 20 healthy controls and 20 subjects with IBD, 15 of whom had Crohn's disease and five with ulcerative colitis. All the subjects consumed Lactobacillus rhamnosus GR-1 and L. reuteri RC-14 supplemented yogurt for 30 days. The presence of putative regulatory T (Treg) cells (CD4+ CD25high) and cytokines in T cells, monocytes and dendritic cells (DC) was determined by flow cytometry from peripheral blood before and after treatment, with or without ex vivo stimulation. Serum and faecal cytokine concentrations were determined by enzyme-linked immunosorbent assays. The proportion of CD4+ CD25high T cells increased significantly (P = 0·007) in IBD patients, mean (95% confidence interval: CI) 0·84% (95% CI 0·55,1·12) before and 1·25% (95% CI 0·97,1·54) after treatment, but non-significantly in controls. The basal proportion of tumour necrosis factor (TNF)-,+/interleukin (IL)-12+ monocytes and myeloid DC decreased in both subject groups, but of stimulated cells only in IBD patients. Also serum IL-12 concentrations and proportions of IL-2+ and CD69+ T cells from stimulated cells decreased in IBD patients. The increase in CD4+ CD25high T cells correlated with the decrease in the percentage of TNF-,- or IL-12-producing monocytes and DC. The effect of the probiotic yogurt was confirmed by a follow-up study in which subjects consumed the yogurt without the probiotic organisms. Probiotic yogurt intake was associated with significant anti-inflammatory effects that paralleled the expansion of peripheral pool of putative Treg cells in IBD patients and with few effects in controls.
