Nutritional Support of Patient with Inflammatory Bowel Disease

Clinical and Nutritional Impact of a Semi-Elemental Hydrolyzed Whey Protein Diet in Patients with Active Crohn's Disease: A Prospective Observational Study

Background: Malnourishment is a common complication in patients with Crohn’s disease. Methods: An observational, prospective study was conducted to assess the nutritional status, disease activity, and stool frequency at baseline and after 12 weeks of treatment with a semi-elemental diet in patients with active Crohn’s disease. Results: A total of 144 patients with Crohn’s disease were included. The nutritional status improved after treatment, resulting in 76.1% of patients at low risk of malnourishment, 20.4% moderately malnourished, and 8.5% severely malnourished after 12 weeks of treatment. Nutritional status improvement was associated with the number of nutritional supplements. Mean albumin levels and body mass index (BMI) improved after 12 weeks of nutritional treatment (from 3.0 g/dL to 3.7 g/dL and from 20.2 kg/m² to 21.1 kg/m², respectively). A significant decrease in HBI was found after 12 weeks of nutritional treatment (from 10.2 to 3.7). The mean number of stools per day decreased with the 12 week semi-elemental diet (from 4.6 stools/day to 1.7 stools/day). Conclusion: In this observational study, the semi-elemental diet seemed effective in improving the nutritional status, disease activity, and stool frequency in patients with active Crohn’s disease.

Medication Belief is Associated with Improved Adherence to Exclusive Enteral Nutrition in Patients with Crohn's Disease

BACKGROUND

The prevalence of Crohn's disease (CD) has been increasing rapidly in China, and the role of exclusive enteral nutrition (EEN) in the management of adult patients with active CD is evolving. Adherence is a key factor in the effective treatment of many chronic diseases.

AIM

The aim of this study was to assess adherence to EEN of CD patients and to evaluate the relationship between medication belief and EEN adherence.

METHODS

A cross-sectional study was conducted, and demographic information, adherence to EEN, and beliefs about EEN were investigated. Medication belief was measured using the Beliefs about Medicines Questionnaire (BMQ)-Specific.

RESULTS

In all, 131 CD patients completed the questionnaire and were enrolled in this study. The high adherence rate was 73.3% (96 of 131 patients), and we found that medication belief, residency, medical insurance, and history of enteral nutrition therapy were factors affecting EEN adherence. More patients with a high BMQ score had high adherence to EEN (n = 54, 56.2%) compared to those with a low BMQ (n = 42, 43.8%). Moreover, price, taste, storage method, portability, and purchase convenience of EEN were not associated with adherence.

CONCLUSION

The adherence to EEN among patients with CD is relatively high and is related to medication belief, residency and history of enteral nutrition. The type of enteral nutrition, taste, storage, and convenience of purchase were not associated with EEN adherence. Future study is warranted to explore the possible role of improving patients' beliefs in increasing adherence.

Recent update on lactic acid bacteria producing riboflavin and folates: application for food fortification and treatment of intestinal inflammation

Lactic acid bacteria (LAB), widely used as starter cultures for the fermentation of a large variety of food, can improve the safety, shelf life, nutritional value and overall quality of the fermented products. In this regard, the selection of strains delivering health-promoting compounds is now the main objective of many researchers. Although most LAB are auxotrophic for several vitamins, it is known that certain strains have the capability to synthesize B-group vitamins. This is an important property since humans cannot synthesize most vitamins, and these could be obtained by consuming LAB fermented foods. This review discusses the use of LAB as an alternative to fortification by the chemical synthesis to increase riboflavin and folate concentrations in food. Moreover, it provides an overview of the recent applications of vitamin-producing LAB with anti-inflammatory/antioxidant activities against gastrointestinal tract inflammation. This review shows the potential uses of riboflavin and folates producing LAB for the biofortification of food, as therapeutics against intestinal pathologies and to complement anti-inflammatory/anti-neoplastic treatments.

Impact of biological therapy on body composition of patients with Chron's disease

Introduction:

Protein-energy malnutrition in Crohn's disease (CD) has been reported in 20 to 92% of patients, and is associated with increased morbidity and mortality and higher costs for the health system. Anti-TNF drugs are a landmark in the clinical management, promoting prolonged remission in patients with CD. It is believed that the remission of this disease leads to nutritional recovery. The effect of biological therapy on body composition and nutritional status is unclear.

Method:

Prospective study of body assessment by bioelectrical impedance method in patients with moderate to severe CD undergoing treatment with infliximab. The main outcome was the body composition before and after 6 months of anti-TNF therapy.

Results:

There was a predominance of females (52%) with a mean age of 42±12 years. Most patients were eutrophic at baseline and remained so. There was an increase in all parameters of body composition after anti-TNF treatment: BMI (22.9±3.2 versus 25±3.8; p=0.005), waist circumference (88.1±6.7 versus 93.9±7.7; p=0.002), lean mass index (17.5±2.2 versus 18.2±2.3; p=0.000) and fat mass index (5.5±2.3 versus 6.8±2.3; p=0.000). Phase angle remained unchanged (6.2 versus 6.8; p=0.94).

Conclusion:

After therapy with IFX, all components of body composition increased, except for phase angle. The substantial increase in fat mass index and waist circumference led to concern regarding cardiovascular risk and, thus, to the need for further studies.

Preoperative Nutritional Conditioning of Crohn's Patients-Systematic Review of Current Evidence and Practice

Crohn’s disease is an incurable and frequently progressive entity with major impact on affected patients. Up to half of patients require surgery in the first 10 years after diagnosis and over 75% of operated patients require at least one further surgery within lifetime. In order to minimize surgical risk, modifiable risk factors such as nutritional status need to be optimized. This systematic review on preoperative nutritional support in adult Crohn’s patients between 1997 and 2017 aimed to provide an overview on target populations, screening modalities, routes of administration, and expected benefits. Pertinent study characteristics (prospective vs. retrospective, sample size, control group, limitations) were defined a priori. Twenty-nine studies were retained, of which 14 original studies (9 retrospective, 4 prospective, and 1 randomized controlled trial) and 15 reviews. Study heterogeneity was high regarding nutritional regimens and outcome, and meta-analysis could not be performed. Most studies were conducted without matched control group and thus provide modest level of evidence. Consistently, malnutrition was found to be a major risk factor for postoperative complications, and both enteral and parenteral routes were efficient in decreasing postoperative morbidity. Current guidelines for nutrition in general surgery apply also to Crohn’s patients. The route of administration should be chosen according to disease presentation and patients’ condition. Further studies are needed to strengthen the evidence.
