BACKGROUND & AIMS Treatment of recurrent Clostridium difficile infection (CDI) with antibiotics leads to recurrences in up to 50% of patients. We investigated the efficacy of fecal transplantation in treatment of recurrent CDI. METHODS We reviewed records from 70 patients with recurrent CDI who had undergone fecal transplantation. Fecal transplantation was performed at colonoscopy by infusing fresh donor feces into cecum. Before transplantation, the patients had whole-bowel lavage with polyethylene glycol solution. Clinical failure was defined as persistent or recurrent symptoms and signs, and a need for new therapy. RESULTS During the first 12 weeks after fecal transplantation, symptoms resolved in all patients who did not have strain 027 C difficile infections. Of 36 patients with 027 C difficile infection, 32 (89%) had a favorable response; all 4 nonresponders had a pre-existing serious condition, caused by a long-lasting diarrheal disease or comorbidity and subsequently died of colitis. During the first year after transplantation, 4 patients with an initial favorable response had a relapse after receiving antibiotics for unrelated causes; 2 were treated successfully with another fecal transplantation and 2 with antibiotics for CDI. Ten patients died of unrelated illnesses within 1 year after transplantation. No immediate complications of fecal transplantation were observed. CONCLUSIONS Fecal transplantation through colonoscopy seems to be an effective treatment for recurrent CDI and also for recurrent CDI caused by the virulent C difficile 027 strain.

Abstract Objective. Endoscopically confirmed mucosal healing has become an important therapeutic goal in the treatment of Crohns disease (CD). The role of clinical indices, such as the Crohns disease activity index (CDAI) and the Harvey–Bradshaw index (HBI), and surrogate markers, such as C-reactive protein (CRP) and fecal calprotectin, to indicate remission determined by endoscopy needs to be clarified. We analyzed the role of surrogate markers and clinical indices, separately and in combination, by comparing them with endoscopically scored disease activity in biologically treated CD patients. Material and methods. Prospectively collected data of all patients with inflammatory bowel disease treated with tumor necrosis factor alpha antibodies in a tertiary center between 2007 and 2010. Altogether 210 endoscopies in 64 CD patients were analyzed. The simple endoscopic score for Crohns disease (SES-CD) was used for scoring disease activity and compared with available data on concurrent CDAI, HBI, CRP, and calprotectin. Results. Endoscopic activity demonstrated a stronger correlation with calprotectin and CRP than with the clinical indices. Neither the clinical indices nor CRP was reliable at identifying endoscopic remission. However, calprotectin alone identified endoscopic remission with a sensitivity of 84% and specificity of 74%, but was beaten, although not statistically significantly, by a combined index, based on calprotectin and the HBI. Conclusions. Clinical scores commonly used in the assessment of disease activity are unreliable at differentiating endoscopic remission from active CD. Despite this, a score based on a combination of fecal calprotectin and the HBI is a new promising tool for identifying endoscopic remission.

Faecal microbiota transplantation (FMT) is an important therapeutic option for Clostridium difficile infection. Promising findings suggest that FMT may play a role also in the management of other disorders associated with the alteration of gut microbiota. Although the health community is assessing FMT with renewed interest and patients are becoming more aware, there are technical and logistical issues in establishing such a non-standardised treatment into the clinical practice with safety and proper governance. In view of this, an evidence-based recommendation is needed to drive the practical implementation of FMT. In this European Consensus Conference, 28 experts from 10 countries collaborated, in separate working groups and through an evidence-based process, to provide statements on the following key issues: FMT indications; donor selection; preparation of faecal material; clinical management and faecal delivery and basic requirements for implementing an FMT centre. Statements developed by each working group were evaluated and voted by all members, first through an electronic Delphi process, and then in a plenary consensus conference. The recommendations were released according to best available evidence, in order to act as guidance for physicians who plan to implement FMT, aiming at supporting the broad availability of the procedure, discussing other issues relevant to FMT and promoting future clinical research in the area of gut microbiota manipulation. This consensus report strongly recommends the implementation of FMT centres for the treatment of C. difficile infection as well as traces the guidelines of technicality, regulatory, administrative and laboratory requirements.

BACKGROUND AND AIMS Patients with inflammatory bowel diseases (IBD) show increased risk for other immune-mediated diseases such as arthritis, ankylosing spondylitis, and some pulmonary diseases. Less is known about the prevalence of other chronic diseases in IBD, and the impact of comorbidity on health-related quality of life (HRQoL). METHODS The study population comprised 2831 IBD patients recruited from the National Health Insurance register and from a patient-association register. Study subjects completed generic 15D and disease-specific IBDQ questionnaires. The Social Insurance Institution of Finland provided data on other chronic diseases entitling patients to reimbursed medication. For each study subject, two controls, matched for age, sex, and hospital district, were chosen. RESULTS A significant increase existed in prevalence of connective tissue diseases, pernicious anemia and asthma. Furthermore, coronary heart disease (CHD) occurred significantly more frequently in IBD patients than in their peers (p=0.004). The difference was, however, more clearly seen in females (p=0.014 versus 0.046 in males). Active and long-lasting IBD were risk factors. Concomitant other chronic diseases appeared to impair HRQoL. Asthma, hypertension and psychological disorders had an especially strong negative impact on HRQoL, as observed with both the generic and disease-specific HRQoL tools. CONCLUSIONS In addition to many immune-mediated diseases, CHD appeared to be more common in IBD than in control patients, especially in females. The reason is unknown, but chronic inflammation may predispose to atherosclerosis. This finding should encourage more efficacious management of underlying cardiovascular risk factors, and probably also inflammatory activity in IBD.

BACKGROUND AND AIMS This prospective multicenter study examined whether elevated fecal calprotec tin (FC) concentrations after stopping TNFα-blocking therapy can predict clinical or endoscopic relapse. In addition, we evaluated the impact of histological remission on the relapse risk. METHODS We enrolled inflammatory bowel disease (IBD) patients who were in clinical, endoscopic, and FC-based (< 100 μg/g) remission after a minimum 11 months of TNFα-blocking therapy. The patients were followed-up for 12 months after the discontinuation of TNFα-blocking therapy. FC was collected monthly for the first 6 months and thereafter every second month. Ileocolonoscopy was performed at inclusion, at 4 months, at the study end, and at the time of clinical relapse. RESULTS Of 52 enrolled patients, 49 (16 Crohns disease, 33 ulcerative colitis/IBD unclassified) provided the stool samples requested and comprised the study group. During the follow-up, 15/49 (31%) relapsed, whereas 34 (69%) remained in remission. Patients relapsing showed constantly elevated FC levels for a median of 94 (13-317) days before the relapse. Significant increase in median FC levels was seen 2 (p = 0.0014), 4 (p = 0.0056), and 6 (p = 0.0029) months before endoscopic relapse. Constantly normal FC concentrations during the follow-up were highly predictive for clinical and endoscopic remission. Normal FC concentrations in patients with remission were associated with histological remission. CONCLUSION FC seems to increase and remain elevated before clinical or endoscopic relapse, suggesting that it can be used as a surrogate marker for predicting and identifying patients requiring close follow-up in clinical practice.

This study was performed to clarify if diabetic complications are associated with liver enzyme activities in type 1 diabetic outpatients. Elevated activities of serum aminotransferases are a common sign of liver disease and are observed more frequently among people with diabetes than in the general population. Many studies have shown an association between specific diabetic complications and disturbances in various tissues, such as diabetic nephropathy and cardiovascular diseases, but only limited data are available on the possible association between diabetic complications and liver function. We studied 28 patients with type 1 diabetes. Mean age was 43.4+/-9.5 (S.D.), and duration of diabetes 25.2+/-9.7. Limited joint mobility (LJM) was assessed by the Rosenblooms method. Background and proliferative retinopathy, and peripheral symmetrical polyneuropathy were also assessed. Activities of alanine amino transferase (ALT), gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP) in serum were determined. The metabolic control of the diabetes was evaluated by the glycosylated haemoglobin A(1c) (HbA(1c)) level and lipid values were also measured. ALT activity was associated with LJM (P<0.01) and with neuropathy (P<0.01). Association between GGT activity and LJM (P<0.01) and neuropathy (P<0.01) were also found. GGT activity was also associated with the severity of retinopathy (P<0.01). None of these associations was explained by confounding effects of diabetes duration, age, body mass index (BMI), HbA(1c) or alcohol consumption. In conclusion, diabetic complications such as LJM, retinopathy and neuropathy are associated with liver enzyme activities independent of alcohol consumption, BMI and metabolic control of diabetes.

Clostridium difficile can cause severe antibiotic‐associated colitis. Conventional treatments with metronidazole and vancomycin improve symptoms, but after discontinuation of treatment, C. difficile infection (CDI) recurs in a number of patients. Rifaximin is a rifamycin‐based non‐systemic antibiotic that has effect against C. difficile.

Limited Joint Mobility in Non-Insulin- Dependent Diabetic (NIDDM) Patients: Correlation to Control of Diabetes, Atherosclerotic Vascular Disease, and Other Diabetic Complications

Perttu Arkkila; Ilkka Kantola; Jorma Viikari

This study examined the association between limited joint mobility (LJM) and diabetic control, atherosclerotic vascular disease and other diabetic complications in non-insulin-dependent diabetic (NIDDM) patients. LJM was studied in 139 [age (mean +/- SD) 61.3 +/- 12.3 years] NIDDM patients. Limitation of several joints was examined with a goniometer and LJM was classified by the Rosenbloom method. The NIDDM patients were examined for the following diseases: history of myocardial infarction, coronary heart, cerebrovascular and peripheral vascular diseases. The diabetic complications, background and proliferative retinopathy, nephropathy, and neuropathy, were also assessed. The metabolic control of the diabetes was evaluated by the average glycosylated hemoglobin Alc (GHbA kappa) concentration and lipid values were also measured. Mean levels of GHbAlc were 8.9 vs. 8.2% (p < 0.05) in NIDDM patients with and without LJM. NIDDM patients with LJM had a 3.1- (95% confidence interval, 1.2-7.7) and a 4.0-fold risk (95% confidence interval, 1.2-13.0) for coronary heart and cerebrovascular disease respectively, when the confounding effects of age, duration of diabetes and control of diabetes were controlled using stepwise logistic regression analysis. Patients with LJM had a 9.3- (95% confidence interval, 1.1-79.0) and a 3.3-fold risk (95% confidence interval, 1.0-10.5) of proliferative retinopathy and nephropathy respectively, when the confounding effects of age and duration of diabetes were controlled, but the correlation disappeared when control of diabetes was included in the model. In conclusion, the presence of LJM is associated with the control of diabetes and with the presence of coronary heart and cerebrovascular diseases in NIDDM patients.

Abstract Background and aims. Studies performed on patient and disease characteristics predicting the treatment response in tumor necrosis factor alpha antibody (anti-TNF)-treated Crohns disease (CD) have generally been based on clinical data. Only a few studies have assessed the role of endoscopy as a predictor for long-term response for anti-TNF therapy. Our aim was to evaluate the role of early endoscopy in predicting the long-term endoscopic response to anti-TNF in active luminal CD in a clinical setting. Patients and methods. Forty-two patients with active luminal CD, treated for at least 3 months with anti-TNF, either adalimumab (52%) or infliximab (48%), were included in this prospective study. Data on the simple endoscopic score for Crohns disease (SES-CD) at 3 months after therapy commencement, and either data on the SES-CD or surgery after 1 year, were available for all patients. Endoscopic remission was defined as SES-CD 0−2. Results. At 3 months after commencing anti-TNF therapy, 10 patients (24%) were in endoscopic remission. Thirty-three patients continued anti-TNF as maintenance therapy. At 1 year, endoscopic remission (11/33, 33%) was significantly more common in those patients who had been in endoscopic remission at 3 months, compared with those with endoscopically active disease at 3 months (7/10, 70% vs. 4/23, 17%, p = 0.01). The 3-month SES-CD had a sensitivity of 88%, and specificity of 64%, to predict 1-year endoscopic remission in patients who received anti-TNF maintenance therapy. Conclusions. In anti-TNF-treated active luminal CD mucosal healing at 3 months is a strong predictor for long-term endoscopic response.
