Dietary Patterns Associated to Clinical Aspects in Crohn's Disease Patients.

Diet is an important factor in both the pathogenesis and in the clinical course of Crohn's disease (CD). However, data on dietary patterns of CD patients are rather limited in the literature. This cross-sectional study included 60 patients with CD, aged 18-60 years. Dietary intake was assessed using a validated food frequency questionnaire to measure food consumption patterns by principal component analysis (PCA). Multiple regression analysis was performed to investigate the association between dietary patterns and clinical and demographic variables. Three dietary patterns were identified: "Traditional + FODMAP" was associated with symptoms, gender, previous surgeries, and duration of the disease. "Fitness style" was positively associated with physical activity and negatively associated with body mass index and smoking. "Snacks and processed foods" was positively associated with duration of the disease and negatively associated with age. According to the weekly food consumption analysis, patients with active disease consumed less coffee and tea. We found significant associations between the three dietary patterns and the variables, but not with the stage of the disease. Prospective studies are necessary to determine the effects of food consumption patterns on the clinical course of CD.

Impaired nutritional status in outpatients in remission or with active Crohn's disease - classified by objective endoscopic and imaging assessments.

BACKGROUND AND AIMS: Crohn's disease is a chronic inflammatory disease consisting of alternated periods of relapse and remission. The disease is associated with altered body composition and micronutrient deficiencies. This study aimed to evaluate the nutritional status of Crohn's disease outpatients in remission and activity of the disease. METHODS: Patients were classified according to Crohn's Disease Endoscopic Index of Severity or Magnetic Resonance Imaging scan. Anthropometric and biochemical analysis was performed for nutritional status evaluation. RESULTS: A total of 60 patients were evaluated of which 31 were in endoscopic remission (mean Crohn's Disease Endoscopic Index of Severity: 1.76) and 29 in activity (mean Crohn's Disease Endoscopic Index of Severity: 7.88). Regarding markers of fat and lean mass, lower values were observed in the activity group when compared to the remission group (p < 0.05). There was a positive correlation regarding the duration of the disease and the anthropometric parameters in patients with active disease. Interestingly, the prevalence of overweight/obese patients was 55% in remission group and 28% in activity group according to the Body Mass Index classification. In addition, lower levels of iron, folic acid and albumin were also observed in Crohn's disease activity group. CONCLUSIONS: We observed important differences in nutritional markers between patients in remission and activity phases, with higher prevalence of overweight/obese in patients with remission of the disease.

Family history of cancer in Brazil: is it being used?

In developing countries, low budgets make the issue of integrating genetics into clinical practice a challenge, a situation in which the use of family history (FH) becomes important for patient care, as it is a low cost strategy and a risk assessment tool. The purpose of this study was to review medical records of patients with colorectal cancer (CRC) seen in a public University Hospital and evaluate how often FH of cancer is registered. Initially we searched a database for patients who were seen in our hospital between 2002 and 2004 with the diagnosis of CRC. We found 415 patients, 104 of whom were excluded. A total of 311 charts were reviewed and classified into 3 groups. Group A: no FH documented; group B: FH was documented, but FH of cancer was not collected; and group C: FH of cancer was documented. We also investigated what type of information was recorded, in order to verify if important elements were assessed. Ninety-eight charts (31.5%) were classified in group A, 20 (6.5%) in group B, and 193 (62%) in group C. In addition, we observed that important information regarding affected relatives was not collected in most of the charts. In conclusion, we found that although FH of cancer was recorded in 62% of charts of patients with CRC, information that could be relevant for risk assessment and management of at-risk families was missing. Our findings expose an important problem in health education that could reflect negatively in the quality of medical assistance to individuals at risk for familial cancer.
