Changes in coeliac disease behaviour over the years

Abstract

We performed a retrospective study of 325 coeliac children (179 females and 146 males, F/M ratio 1:2), diagnosed from 1984 to 1989. The children were divided into two groups; group A were diagnosed between 1984 and 1986 and group B were diagnosed between 1987 and 1989, when the antigliadin antibody test had been introduced in our routine. The data showed a difference between the number of diagnoses in the two groups, 117 in group A versus 208 in group B, with a yearly increment of new cases. In both groups, the onset of the disease occurred within the 2nd year of life, in most cases (group A, 88.9%; group B 89.4%) showing a mode at approximately the 9th month. Diagnosis was made within the 2nd year of life in the majority of cases (group A, 80.3%; group B, 87.4%), showing a mode of approximately the 12th month. In both groups, chronic diarrhoea was the most frequent symptom (75.2% in group A and 70.2% in group B), while minor symptoms, such as isolated short stature, pallor, delayed puberty and others, did not show any important change. We conclude that in Sicily, in recent years, the incidence of coeliac disease has been increasing. The most representative clinical form is the classic one, with onset within the 2nd year of life, and chronic diarrhoea, growth failure and abdominal distention as key symptoms.
