Apresentação clínica de doença celíaca em crianças durante dois períodos, em serviço universitário especializado

Celiac disease in the developing world

The prevalence of celiac disease (CD) in many developing countries is similar to that of developed areas, in both low- and high-risk groups. The disorder is underestimated because of lack of disease awareness. CD is strongly associated with HLA-DQ2 in developing countries. Clinical presentation may be characterized by chronic diarrhea, anemia, stunting and increased mortality. Few studies have addressed atypical or silent CD. Diagnosis is initially made by serologic tests and is confirmed by small intestinal biopsies. In developing countries the adherence to the treatment is still difficult because of poor availability of dedicated gluten-free food.

[Clinical profile of Santa Catarina members of Brazilian Celiac Association]

BACKGROUND

Celiac disease is an enteropathy induced by gluten in genetically predisposed individuals.

AIM

To establish the demographic and clinical characteristics of this disease in Santa Catarina State, Brazil.

METHODS

A descriptive transversal study was performed involving members of a regional celiac association, to whom a questionnaire focusing various aspects of the disease was sent.

RESULTS

From a total of 506 members, 145 (28.7%) were enrolled in the study--all of them biopsy-proven celiacs. Their mean age was 30.8 years (range, 3.3-82.5 years). Female to male rate was 2.1:1. The mean age at diagnosis was 16 years for men and 26.7 years for women. Most frequently reported symptoms were: abdominal distention (71.8%), abdominal pain (71%) and diarrhea (65.5%). Anemia, aphthous ulcers and constipation were more related by women, while diarrhea and low weight were more frequent in men. Only 42.1% of the participants had been submitted to biopsies compatible with a correct investigation of the disease (44.2 % had been submitted to biopsy only after gluten exclusion of the diet and 11.7% did not mentioned whether they were in a gluten-free diet when biopsied). Only 61.4% had been submitted to serological tests for diagnostic or dietary control purposes. Associated diseases were related by 65% of the individuals, of which the most common was lactose intolerance (33%). Vitaminic or mineral supplementation was indicated to 45% and only 32.5% have had bone mineral density measured. Of these, 59% had altered results.

CONCLUSIONS

The results suggest a tendency of diagnosis of celiac disease in older ages, specially among women. This may indicate the necessity of improving public and medical knowledge in Santa Catarina concerning the diagnosis and treatment of this disease.
