RESUMO

OBJETIVO:

Determinar a prevalência da doença celíaca e descrever as alterações histológicas, manifestações clínicas e condições associadas de um grupo de familiares de primeiro grau de celíacos na cidade de Recife (PE), Nordeste do Brasil.

MÉTODO:

O estudo foi realizado em ambulatórios de gastropediatria da cidade de Recife. Foram incluídos no estudo 174 familiares de primeiro grau submetidos à pesquisa do anticorpo antitransglutaminase IgA. Os familiares com sorologia positiva foram convidados a realizar biópsia do intestino delgado (classificadas segundo Marsh) e avaliação do peso, estatura, manifestações clínicas e condições associadas à doença celíaca. Foram utilizados os testes do qui-quadrado e de Fisher para avaliar as diferenças, considerando-se significativo o valor de p < 0,05.

RESULTADOS:

O anticorpo antitransglutaminase IgA foi positivo em 20,1 por cento (34/174) dos familiares (IC95 por cento 14,6-26,5). Não se observou diferença na positividade da sorologia quanto ao grau de parentesco, nem quanto ao sexo. Vinte e dois pacientes submeteram-se a biópsia. Treze apresentaram alterações histológicas grau III de Marsh; sete, grau I; e dois, grau zero, conferindo uma prevalência presumível de 11,5 por cento. Todos os pacientes, exceto um, eram sintomáticos; o único paciente sem sintomas tinha baixa estatura.

CONCLUSÃO:

A prevalência de doença celíaca nesse grupo de familiares foi elevada. Todos os novos casos identificados tinham sintomas ou condições associadas. Nesse grupo, houve uma frequência elevada de indivíduos com sorologia positiva, sintomatologia sugestiva de doença celíaca e sem evidência de atrofia vilositária na mucosa intestinal.
ABSTRACT

OBJECTIVE:

To determine the prevalence of celiac disease and to describe the histological alterations, clinical manifestations, and conditions associated with a group of first-degree relatives of celiac disease patients in the municipality of Recife, Northeast Brazil.

METHOD:

The study was conducted in outpatient clinics of pediatric gastroenterology located in Recife. We included in the study 174 first-degree relatives who were screened for the anti-transglutaminase IgA antibody. Those relatives who had positive serological tests were invited to undergo a small intestine biopsy (classified according to Marsh). They were also evaluated regarding weight, height, clinical symptoms and conditions associated with celiac disease. The chi-square test and Fisher's exact test were used to assess the differences with a significance level of p < 0.05.

RESULTS:

The anti-transglutaminase IgA antibody was positive for 20.1 percent (34/174) of the relatives (95 percentCI 14.6-26.5). There was no difference in terms of positive serological tests regarding either degree of kinship or sex. Twenty-two patients underwent biopsy. Thirteen had histological alterations classified as Marsh stage 3; seven had stage 1; and two had stage zero, with a probable prevalence of 11.5 percent. All patients, except for one, had symptoms; the only patient with no symptoms was short.

CONCLUSION:

Celiac disease prevalence in this group of relatives was high. All new cases identified were symptomatic or had associated conditions. In this group, there was a high frequency of individuals with positive serological tests, symptoms suggestive of celiac disease, and no evidence of villous atrophy in the intestinal mucosa.
