Ingested Matter Affects Intestinal Lesions in Crohn’s DiseaseGregor Bartel, Ilse Weiss, Karl Turetschek,Wolfgang Schima, Andreas Pu¨spo¨k,Thomas Waldhoer, and Christoph Gasche Inflamm Bowel Dis 2008;14:374 –382

Environmental factors of the modern Western life- style may trigger Crohn’s disease in susceptible individuals. Because such factors could be part of ingested matter, they intended to improve intestinal Crohn’s lesions by exclusion thereof.
3Introduction
Methods Patients
5 pilot cases with CD
Primary:Assesed by MRI and endoscopy
14 pt with mild-to-moderate CD
Secondary:Sonography, the CDAI
and the IBDQ
Ulceration of the left-sided colon or a significant lesion of the small bowel or right-sided colon that was assessable by means of MRI.Some patient will be excluded.
Located in the neoterminal ileum in 2 casesIn the upper small bowel in the remaining 3 casesJudged by global physician assessment3 female, 2 male, median age 36, median duration of disease 7 years.
4
• 3 intramuscular multivitamin injections at weeks 0, 3, and 6.• Keep a nutrition and symptom diary throughout the study. • Contacted by the dietician.
• Highly restricted diet composed of red meat, certain sourdough bread, rape oil, and fresh butter•Fruits and vegetables were excluded
• Low-fat, high-carbohydrate diet that is complete in nutrients, but to avoid fiber-rich fruits and vegetables• Not to eat any red meat.

Control group
Diedary Intervention
Active group
All patients showed significant improvement of bowel symptoms within 4 to 6 weeks.
Due to their individual success, 4 patients continued on a broadened organic diet including fruits and vegetables and were successfully avoiding surgery during the following years.
Result(Pilot Cases) 6
ResultAssesed by MRI
7
Transabdominal bowel sonography(TABS) showed improvement in 4 out of 5 patients in the active and 1 out of 8 in the control group.
At the end of the follow-up period the TABS scores further improved in 1 case and worsened in 2 of the active group.
After 6 weeks the CDAI dropped in both groups.
Result 8
Environmental factors with a Western lifestyle might cause CD in genetically susceptible individuals.
Complex nutritional changes, should be able to improve or heal intestinal lesions in CD.
Discussion 9
High drop-out rate.
Difficult to relate our results to previous dietary studies in CD as they typically focused on single dietary factors such as sugar or fat and did not assess intestinal healing as an endpoint.
Discussion 10
Ingested matter as part of the modern Western lifestyle may cause persistence of intestinal Crohn’s lesions.
Conclusions 11
Dietary Patterns and Risk for Crohn’s Disease in ChildrenSavio DS, Emile Levy, David Mack, David Israel, Philippe Lambrette and Parviz Ghadirian. Inflamm Bowel Dis 2008;14:367–373
12
Some dietary foods are considered protective, whereas others are thought to enhance the risk for Crohn’s disease (CD). The evidence, however, is inconsistent.
Introduction 13
MethodsNewly diagnosed CD cases(< 20 years of age)
Using a validated food frequency questionnaire(FFQ) and Youth Adolescent Questionnaire (YAQ) .
Factor analyses and unconditional logistic regression.
Controls were patients visiting the orthopedic clinics and random-digit dialing (RDD)
14
Result 15
15 patterns were identified. 4 patterns were interpretable and were retained. 16 patterns were identified, of which 4 patterns were retained.16
Cronbach’s alphas:
Boys: 0.82, 0.65, 0.70, and 0.53 for patterns partial western, prudent, miscellaneous, and meat
Girls: 0.80, 0.60, 0.79, and 0.57 for patterns western, prudent, cheese- snack, and beverages
17
Dietary pattern studies have provided valuable information on the etiopathogenesis of diverse complex diseases.
Western pattern could confer risk for CD among girls and that a prudent pattern could protect both girls and boys from acquiring CD.
Discussion 18
Specific dietary patterns could be associated with higher or lower risks for CD in children.
Conclusions 19
Vitamin D-mediated calcium absorption in patientswith clinically stable Crohn’s disease: A pilot studyMeena K, Natasha B. Khazai, Thomas R. Ziegler, Mark S. NanesSteven A. Abrams and Vin Tangpricha Mol. Nutr. Food Res. 2010, 54, 1085–1091
20
Vitamin D is the critical hormone for intestinal absorption of calcium.
Crohn’s disease (CD), rheumatoid arthritis (RA) and menopause are examples of conditions associated with increased fracture risk, impaired calcium absorption and an increased inflammatory state.
Introduction 21

Result 24
Result 25
CD patients have a normal response to vitamin D in enhancing the efficacy of calcium absorption.
Conclusions 26
Summary Western lifestyle and specific dietary
patterns could be increase the risks for CD patient. We could use the dietary patterns that, characterized by fruit, vegetable and high amount of vitamin D to avoid them.
