Abstract
BACKGROUND The Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) initiative of the International Organization for the Study of Inflammatory Bowel Diseases (IOIBD) has proposed treatment targets in 2015 for adult patients with inflammatory bowel disease (IBD). We aimed to update the original STRIDE statements for incorporating treatment targets in both adult and pediatric IBD. METHODS Based on a systematic review of the literature and iterative surveys of 89 IOIBD members, recommendations were drafted and modified in 2 surveys and 2 voting rounds. Consensus was reached if ≥75% of participants scored the recommendation as 7 to 10 on a 10-point rating scale. RESULTS In the systematic review, 11,278 manuscripts were screened, of which 435 were included. The first IOIBD survey identified the following targets as most important: clinical response and remission, endoscopic healing, and normalization of C-reactive protein/erythrocyte sedimentation rate and calprotectin. Fifteen recommendations were identified, of which 13 were endorsed. STRIDE-II confirmed STRIDE-I long-term targets of clinical remission and endoscopic healing and added absence of disability, restoration of quality of life, and normal growth in children. Symptomatic relief and normalization of serum and fecal markers have been determined as short-term targets. Transmural healing in Crohn's disease and histological healing in ulcerative colitis are not formal targets but should be assessed as measures of the remission depth. CONCLUSIONS STRIDE-II encompasses evidence- and consensus-based recommendations for treat-to-target strategies in adults and children with IBD. This frameworkshould be adapted to individual patients and local resources to improve outcomes.

Abstract
BACKGROUND & AIMS There is a need for a scoring system that provides a comprehensive assessment of structural bowel damage, including stricturing lesions, penetrating lesions, and surgical resection, for measuring disease progression. We developed the Lémann Index and assessed its ability to measure cumulative structural bowel damage in patients with Crohn's disease (CD). METHODS We performed a prospective, multicenter, international, cross-sectional study of patients with CD evaluated at 24 centers in 15 countries. Inclusions were stratified based on CD location and duration. All patients underwent clinical examination and abdominal magnetic resonance imaging analyses. Upper endoscopy, colonoscopy, and pelvic magnetic resonance imaging analyses were performed according to suspected disease locations. The digestive tract was divided into 4 organs and subsequently into segments. For each segment, investigators collected information on previous operations, predefined strictures, and/or penetrating lesions of maximal severity (grades 1-3), and then provided damage evaluations ranging from 0.0 (no lesion) to 10.0 (complete resection). Overall level of organ damage was calculated from the average of segmental damage. Investigators provided a global damage evaluation (from 0.0 to 10.0) using calculated organ damage evaluations. Predicted organ indexes and Lémann Index were constructed using a multiple linear mixed model, showing the best fit with investigator organ and global damage evaluations, respectively. An internal cross-validation was performed using bootstrap methods. RESULTS Data from 138 patients (24, 115, 92, and 59 with upper tract, small bowel, colon/rectum, and anus CD location, respectively) were analyzed. According to validation, the unbiased correlation coefficients between predicted indexes and investigator damage evaluations were 0.85, 0.98, 0.90, 0.82 for upper tract, small bowel, colon/rectum, anus, respectively, and 0.84 overall. CONCLUSIONS In a cross-sectional study, we assessed the ability of the Lémann Index to measure cumulative structural bowel damage in patients with CD. Provided further successful validation and good sensitivity to change, the index should be used to evaluate progression of CD and efficacy of treatment.

Extraintestinal manifestations and complications in IBD.
Ott, C, Schölmerich, J
Nature reviews. Gastroenterology & hepatology. 2013;(10):585-95
Abstract
More than one-third of patients with IBD are affected by extraintestinal manifestations or extraintestinal complications beyond the intestinal manifestation of the disease. The most common manifestations include arthropathies, mucocutaneous and ophthalmological manifestations, as well as conditions affecting the hepatobiliary system, both in Crohn's disease and ulcerative colitis. However, less frequent manifestations, such as pulmonary or neurological manifestations, should also be considered in patients with IBD. Several extraintestinal manifestations follow the course of the underlying intestinal activity, whereas others are independent from the intestinal inflammation. Extraintestinal complications such as iron-deficiency anaemia and osteoporosis are consequences of the intestinal disease or of disease-specific treatment. As extraintestinal manifestations and complications strongly influence quality of life, and to avoid severe complications, adequate treatment is mandatory in affected patients. We provide a comprehensive overview of different extraintestinal manifestations and complications, including their management, in patients with IBD.

Plain language summary
Environmental factors are thought to play a part in the development of or exacerbation of symptoms in Crohn's disease (CD), and patients often implicate food as a contributing factor. Immunoglobulin E (IgE) food reactions can be rare in IBD and immunoglobulin G (IgG) testing can be controversial, this study set out to compare IgG antibody reactions in 79 CD patients and 20 healthy individuals. The pilot study measured IgG levels against 271 foods in the blood. It then went on to measure stool frequency, abdominal pain and general well-being following a 6 week specific elimination diet (based on foods identified by the IgG testing) or a 6 week sham diet. 23 participants were included in the follow on 12 week, cross-over double blinded study. Eosinophil-derived neurotoxin (EDN) in stool was also measured to evaluate disease activity. The pilot study showed a significantly higher IgG reaction in the CD patients. In the follow-up study there was a decrease in stool frequency, abdominal pain and general well-being during the specific diet compared to the sham diet. EDN was found to decrease in both the specific and sham diet. It was concluded that IgG antibodies may contribute to CD but the mechanism is still not clear.
Abstract
BACKGROUND Environmental factors are thought to play an important role in the development of Crohn's disease (CD). Immune responses against auto-antigens or food antigens may be a reason for the perpetuation of inflammation. METHODS In a pilot study, 79 CD patients and 20 healthy controls were examined for food immunoglobulin G (IgG). Thereafter, the clinical relevance of these food IgG antibodies was assessed in a double-blind cross-over study with 40 patients. Based on the IgG antibodies, a nutritional intervention was planned. The interferon (IFN)gamma secretion of T cells was measured. Eosinophil-derived neurotoxin was quantified in stool. RESULTS The pilot study resulted in a significant difference of IgG antibodies in serum between CD patients and healthy controls. In 84 and 83% of the patients, respectively, IgG antibodies against processed cheese and yeast were detected. The daily stool frequency significantly decreased by 11% during a specific diet compared with a sham diet. Abdominal pain reduced and general well-being improved. IFNgamma secretion of T cells increased. No difference for eosinophil-derived neurotoxin in stool was detected. CONCLUSION A nutritional intervention based on circulating IgG antibodies against food antigens showed effects with respect to stool frequency. The mechanisms by which IgG antibodies might contribute to disease activity remain to be elucidated.

[Treatment of inflammatory bowel disease].
Schölmerich, J
Praxis. 2007;(9):337-43
Abstract
Standard treatment for IBD with 5-ASA, steroids and immunosuppressants is rather effective and currently optimized using combinations of drugs or application routes. Among the biologics only infliximab has reached the therapeutic arsenal for Crohn's disease--it is as well effective in some patients with ulcerative colitis. Early aggressive treatment thus far is not established. Hormones and growth factors may play a role. Probiotics have a place in the treatment in particular for ulcerative colitis.

Abstract
The objective of this study was to assess the efficacy and safety of two regimens of irinotecan, combined or alternated with bolus 5-fluorouracil (5-FU) and folinic acid (FA), and the Mayo Clinic regimen as first-line therapy for colorectal cancer (CRC). A total of 152 patients with advanced CRC were randomised, and 149 patients were treated intravenously by irinotecan 125 mg/m2, FA 20 mg/m2 followed by 5-FU 500 mg/m2 bolus, weekly for 4 weeks (arm A, Saltz regimen; n=46), or irinotecan 350 mg/m2 alternating with FA 20 mg/m2/day followed by 5-FU bolus 425 mg/m2/day for 5 days (arm B; n=53), or FA 20 mg/m2/ day followed by 5-FU bolus 425 mg/m2/day over 5 days every 4 weeks (arm C, Mayo Clinic regimen; n=50). Patients were analyzed for tumor response, time to progression, overall survival, safety and quality of life. The overall response rate for evaluable patients in arm A was 33% [95% confidence interval (CI), 17-49%], in arm B was 32% (95% CI, 16-49%) and in arm C was 26% (95% CI, 12-40%). Median times to progression were 7.9, 7.0 and 6.9 months and median survival times were 22.2, 17.0 and 18.2 months for arms A, B and C, respectively, in the intention-to-treat population. The main grade 3-4 adverse events were neutropenia (7%, 39% and 12%) and diarrhea (6%, 21% and 18%). In conclusion, both regimens containing irinotecan were active and well tolerated in patients with advanced CRC.

Patient education in inflammatory bowel disease does not influence patients knowledge and long-term psychosocial well-being.
Bregenzer, N, Lange, A, Fürst, A, Gross, V, Schölmerich, J, Andus, T
Zeitschrift fur Gastroenterologie. 2005;(4):367-71
Abstract
BACKGROUND AND AIMS Patient education is accepted in many disciplines as a valid component of disease management in chronic diseases. The aim of this prospective study was to analyze the effects of an education program in patients with inflammatory bowel disease. METHODS 145 patients with inflammatory bowel disease were prospectively included: 73 were educated in four sessions, 72 were educated after the one year evaluation period (control group). The following topics were presented: pathogenesis, diagnostic procedures, course of disease, medical and surgical treatment, nutrition, social problems and support, stress management, and coping with the disease. RESULTS The repeated measurement two-way analysis of variances showed no effects of the patient education program on disease-related knowledge, depression and quality of life. CONCLUSION This patient education program was not able to increase disease-related knowledge or psychosocial variables in patients with IBD. However, most of the patients were very satisfied with the education program, since as judged by their own assessment it helped them to act responsibly for themselves and their disease.

Association of Crohn's disease and latent celiac disease: a case report and review of the literature.
Schedel, J, Rockmann, F, Bongartz, T, Woenckhaus, M, Schölmerich, J, Kullmann, F
International journal of colorectal disease. 2005;(4):376-80
Abstract
BACKGROUND Crohn's disease is a chronic inflammatory disease of the intestine potentially affecting all parts of the intestine with predilection sites in the terminal ileum and proximal colon. Its prevalence in Western Europe is 20-40/100,000 with equal affection of both sexes and familiar accumulation. Histopathologically, it is characterized by a discontinuous, segmental manifestation and implication of all intestinal layers. Celiac disease, on the other hand, is defined by histologically proven villous atrophy associated with hyperplasia of crypts, lymphocytic infiltration and clinical improvement after a gluten-free diet. CASE REPORT We report the case of a 52-year-old man presenting with long-term diarrhea and loss of weight associated with Crohn's disease. After interventional therapy for an unstable coronary artery syndrome and medical therapy for hyperthyroidism, the diarrhea stopped only after maintaining a gluten-free diet. A latent form of celiac disease (clinical symptoms, improvement after gluten-free diet, detection of anti-gliadin IgA antibodies, negative histology) was diagnosed. CONCLUSION To our knowledge, this is the first report on the association of Crohn's disease and the latent form of celiac disease in the same patient. Whereas in most cases, Crohn's disease develops secondary to a pre-existing celiac disease, in our patient, latent celiac disease was diagnosed years after the onset of and therapy for Crohn's disease.

[Extraintestinal manifestations of inflammatory bowel disease].
Rogler, G, Schölmerich, J
Medizinische Klinik (Munich, Germany : 1983). 2004;(3):123-30
Abstract
Extraintestinal manifestations of Crohn's disease and ulcerative colitis are found in > 50% of all patients. These extraintestinal manifestations sometimes impair the overall life quality much more than the bowel-related symptoms. Extraintestinal manifestations need to be distinguished from secondary diseases or complications of inflammatory bowel diseases, as they require a different and specific therapy. Complications of the intestinal disease, such as vitamin deficiency or osteoporosis, can be treated specifically by substitution of vitamin D, calcium, or other vitamins. However, extraintestinal manifestations of Crohn's disease and ulcerative colitis, such as primary sclerosing cholangitis, arthritis or granulomatous inflammation of the skin, lung, or liver, are much more difficult to treat sufficiently. Almost every organ can be a localization of extraintestinal symptoms of inflammatory bowel diseases. It is important to acquire knowledge on these extraintestinal manifestations of Crohn's disease and ulcerative colitis to start the respective treatment early. Perhaps even more important, these extraintestinal symptoms can be the primary manifestation of Crohn's disease and ulcerative colitis. Therefore, they have to be recognized as extraintestinal manifestations to adequately treat the intestinal disease.

Endocrine research. 2004;(3):443-53
Abstract
Plasminogen activator inhibitor-1 (PAI-1) levels were found to be associated with obesity, indicating that adipocytes might influence PAI-1 plasma levels. In addition, the 4G/5G promoter polymorphism of the PAI-1 gene possibly modulates PAI-1 gene transcription and, as a consequence, PAI-1 plasma levels. Metabolic parameters, diabetes complications, PAI-1 plasma levels, and PAI-1 promoter genotypes were determined and were tested for correlation in 547 Caucasian patients with type 2 diabetes. Genotyping was performed by using allele-specific PCR, and PAI-1 plasma levels were measured in 547 well-characterized subjects with type 2 diabetes. The allelic frequencies of the polymorphism (0.56 for the 4G-genotype, 0.44 for the 5G-genotype) were not different from those observed in nondiabetic controls. The PAI-1 concentration was positively associated with MI, but not with the 4G/5G polymorphism. Statistical analysis of metabolic parameters, diabetic complications, and the 4G/5G polymorphism revealed that serum fibrinogen levels were significantly higher in the 4G/4G subgroup compared with the 4G/5G and 5G/5G subgroups. The correlation between serum fibrinogen and 4G allele remained significant, even when additional variables, such as gender, age, BMI, duration of diabetes, and HbA1c, were controlled. In patients with type 2 diabetes mellitus, the PAI-1 4G/5G promoter polymorphism does not predict PAI-1 plasma levels and is not associated with common metabolic parameters besides fibrinogen levels.
