[Deficient lactose digestion and intolerance in a group of patients with chronic nonspecific ulcerative colitis: a controlled, double-blind, cross-over clinical trial].

Introduction: Despite the fact that the frequency of hypolactasia and lactose intolerance is similar in both chronic idiopathic ulcerative colitis patients and the general population, the elimination of dairy products from the patient's diet is a habitual recommendation. Hypolactasia is common in Mexico, but its relation to chronic idiopathic ulcerative colitis has not been established.

Aims: To evaluate lactose digestion and lactose intolerance in persons with chronic idiopathic ulcerative colitis.

High prevalence of celiac disease in Mexican Mestizo adults with type 1 diabetes mellitus.

Background And Aims: Recent studies have shown that celiac disease (CD) could affect 0.5% to 3% of the general population, including Mexican Mestizos, which represents a complex mixture of genetics, and constitutes the core of Mexican and Latin American populations. However, the association between CD and other conditions, specifically type-1 diabetes mellitus, in this population remains unknown.

Celiac disease could be a frequent disease in Mexico: prevalence of tissue transglutaminase antibody in healthy blood donors.

Introduction/aim: In North America and Europe, the prevalence of celiac disease (CD) might be much greater than expected in previous estimates. Until recently, the prevalence of CD in Latin America remained largely unknown. So far, information regarding CD in Mexico is limited, and it is still considered a rare disease.
