Dietary manipulation of the gut microbiome in inflammatory bowel disease patients: Pilot study
IBD-AID
Consumption of prebiotics, probiotics, and beneficial foods correlated with increased abundance of Clostridia and Bacteroides, commonly depleted in IBD cohorts. We further show that specific foods categorized as prebiotics or adverse foods are correlated to levels of cytokines in serum (i.e., GM-CSF, IL-6, IL-8, TNF-alpha) that play a central role in IBD pathogenesis.

The Crohn's disease exclusion diet for induction and maintenance of remission in adults with mild-to-moderate Crohn's disease (CDED-AD): an open-label, pilot, randomised trial
CDED
CDED with or without partial enteral nutrition was effective for induction and maintenance of remission in adults with mild-to-moderate biologic naive Crohn's disease and might lead to endoscopic remission.

Low-Fat, High-Fiber Diet Reduces Markers of Inflammation and Dysbiosis and Improves Quality of Life in Patients With Ulcerative Colitis
Other Diets - UC
In a cross-over study of patients with UC in remission, we found that a catered LFD or iSAD were each well tolerated and increased quality of life. However, the LFD decreased markers of inflammation and reduced intestinal dysbiosis in fecal samples. Dietary interventions therefore might benefit patients with UC in remission.

A Randomized Trial Comparing the Specific Carbohydrate Diet to a Mediterranean Diet in Adults with Crohn's Disease
SCD,
MED
This study compares the SCD and MD on symptoms, fecal calprotectin and CRP at 6 and 12 weeks finding no statistical significance in these endpoints.

Elemental Diet Therapy Plays a Significant Role in Preventing Surgical Recurrence of Crohn's Disease in the Era of Biologics
PEN
Although univariate analyses revealed that all three treatment strategies had significant effects on surgical recurrence in patients with CD, multivariate analysis revealed that only ED therapy was significantly associated with surgical recurrence rates. Thus, ED therapy plays an important role in the management of CD, even in the era of biological therapies.

Randomised Clinical Trial: Exclusive Enteral Nutrition Versus Standard of Care for Acute Severe Ulcerative Colitis
EEN
Patients on EEN had a shorter hospital stay [median (range) 10 (8-17) vs 13 (8-24) days; P = 0.04], higher day 7 albumin level (34 ± 4 vs 29 ± 3 g/L, P < 0.01), greater reduction in serum C-reactive protein and faecal calprotectin levels (both P = 0.04) and a lower composite outcome of colectomy/hospitalisation at 6 months (16% vs 39%; P = 0.045) compared to SOC.

Multidimensional Impact of Mediterranean Diet on IBD Patients
MED
A significant reduction of malnutrition-related parameters and liver steatosis was observed in both CD and UC patients after short-term dietary intervention based on the adoption of Md, and this was associated with a spontaneous improvement of disease activity and inflammatory markers.

The Specific Carbohydrate Diet and Diet Modification as Induction Therapy for Pediatric Crohn's Disease: A Randomized Diet Controlled Trial
SCD,
mSCD
This study emphasizes the impact of diet in CD. Each diet had a positive effect on symptoms and inflammatory burden; the more exclusionary diets were associated with a better resolution of inflammation.

Effectiveness of Mediterranean Diet's Adherence in children with Inflammatory Bowel Diseases
MED
Children with IBD in remission have a sub-optimal food intake compared to HCs. MD seems to correlate to decreased intestinal inflammation.

Adherence to the Mediterranean Diet Is Associated with Decreased Fecal Calprotectin in Patients with Ulcerative Colitis after Pouch Surgery
MED
In patients with UC after pouch surgery, adherence to MED is associated with decreased calprotectin levels. Thus, MED may have a role in modifying intestinal inflammation in IBD.

Dietary Therapies Induce Rapid Response and Remission in Pediatric Patients With Active Crohn's Disease
CDED,
EEN
For pediatric patients with active CD, dietary therapies (CDED and EEN) induce a rapid clinical response (by week 3). Identification of patients with and without a rapid response to diet might help identify those who, with compliance, will be in clinical remission by week 6 of the diet.

Partial Enteral Nutrition Induces Clinical and Endoscopic Remission in Active Pediatric Crohn's Disease: Results of a Prospective Cohort Study
PEN
The results of our prospective pilot study suggest that PEN, allowing one meal from AID, could be as effective as EEN in inducing clinical and endoscopic remission in children with active CD. However, larger randomized controlled studies are warranted to confirm our findings.
