Immune Response Regulation and Nutritional Status of the Crohn's Disease Patients.

Not Applicable

Completed

• Conditions: Crohn's Disease

• Registration Number: NCT01957423
• Lead Sponsor: University of Campinas, Brazil

Brief Summary

The objective of this study was to evaluate the effect of Whey Protein (WP) and Soy Protein (SP) nutritional supplements on nutritional status and disease activity in Crohn's disease patients.

Detailed Description

The patients were split into two groups: one group was supplemented with whey protein and the other, with soy protein. Participants were assessed at three moments: before starting the intervention and after 8 and 16 weeks. The nutritional status and body composition were measured using bioimpedance analysis, anthropometry and albumin and pre-albumin dosages. Dietary intake was determined by 24-h dietary recalls. The disease activity was evaluated by Crohn's Disease Activity Index, serum cytokines and C-reactive protein dosages.

Primary Outcome Measures

Name	Time	Method
Body mass index	16 weeks	Body mass index (BMI) was calculated from weight and height (kilograms per meter squared) and classified according to the World Health Organization.

Secondary Outcome Measures

Name	Time	Method
Body fat percentage	16 weeks	Body fat was measured using bioimpedance analysis. Whole-body resistance and reactance were measured using a tetrapolar bioelectrical impedance analyzer in accordance with the manufacturer's guidelines (BIODYNAMICS, Model 310e).
Body lean percentage	16 weeks	The body lean mass was measured using bioimpedance analysis. Whole-body resistance and reactance were measured using a tetrapolar bioelectrical impedance analyzer in accordance with the manufacturer's guidelines (BIODYNAMICS, Model 310e).
Mid-arm circumference	16 weeks	Mid-arm circumference was obtained using the tape measure.
Mid-arm muscle circumference	16 weeks	Mid-arm muscle circumference was calculated from mid-arm circumference and triceps skin fold thickness.
Corrected arm muscle area	16 weeks	Corrected arm muscle area was calculated from mid-arm circumference and triceps skin fold thickness.
Crohn's Disease Activity Index	16 weeks	The Crohn's Disease Activity Index was used for evaluation of disease activity.
C-reactive protein	16 weeks
Serum albumin	16 weeks
Pre-albumin	16 weeks
Triceps skin fold thickness	16 weeks	Triceps skin fold thickness was obtained using the Lange skin fold caliper.
