Título

Is dairy products restriction mandatory for Inflammatory Bowel Disease patients: a multinational cross sectional study

Introdução

The role of dairy foods (DFs) in inflammatory bowel disease (IBD) has been controversial and it is debatable if patients with IBD should avoid milk and dairy products or not, as well as the relationship between these foods and symptoms in this population.
This multi centric cross sectional study designed to evaluate is it really necessary to deprive IBD patients from consumption of DFs

Objetivo

To evaluate gastrointestinal (GI) symptoms after consumption of dairy products from all outpatients with IBD during six months and to compare patients treated at the same centers without IBD (non IBD cases)

Método

A multicenter survey with 12 gastroenterology referral centers in 4 countries

Resultados

Overall 1888 cases included (872 IBD patients and 1016 non IBD cases). 56.6% of participant was female with average age of 40.1 years. Racially 79.8% of participant was Caucasian and originally they were citizens of 10 countries. Relative prevalence of IBD was higher in Africans and Indians and the most frequent prevalence of dairy products intolerance seen in Asians. Among IBD patients, 571 cases diagnosed as ulcerative colitis (UC) and 189 participants as Crohn’s disease (CD). Average duration of diagnosis as IBD was 6.8 years (from 2 months to 35 years).
The most prevalent GI symptoms after consumption of all of the dairy products were bloating and abdominal pain. Totally, intolerance of dairy products and lactase deficiency was more prevalent among IBD patients in comparison with non IBD cases (65.5% vs. 46.1%, P = 0.0001). But the rate of GI complains among IBD patients who had not any family history of lactase deficiency, history of food sensitivity or both were 59.91%, 52.87% & 50.33% respectively and similar to non IBD cases (P = 0.68, 0.98 & 0.99 respectively).

Conclusão

The rate of dairy product intolerance among IBD patients without family history of lactase deficiency or history of food sensitivity is similar to non IBD cases and probably there is no reason to deprive them from this important source of dietary calcium, vitamin D and other nutrients.
