[Clinical data on celiac disease with an early or late onset].

Typical symptoms in celiac disease (CD) are usually associated with early onset of the disease, whereas an atypical symptomatology has more often a later onset. The aim of this study was to evaluate the prevalence of some clinical signs and symptoms in children whose CD started before one year of age ("early onset" 135 children, M/F 50/85, mean age at onset 6.9 +/- 1.9 months) and in children whose disease started later ("late onset", M/F 14/26, mean age at onset 26.3 +/- 26.7 months). We analyzed: a) time lapse between gluten introduction and onset of symptoms, b) prevalence of patients with gastrointestinal symptoms alone and that of patients with gastrointestinal plus extraintestinal symptoms, c) frequency of each symptom. We then evaluated the influence of breast feeding and age of gluten introduction on time lapse. Our results showed that typical gastrointestinal symptoms, like diarrhea anorexia and abdominal distension prevailed both in children with early and late onset; whereas failure to thrive was significantly more frequent in children with an early onset CD (p < 0.01). Breast feeding delayed onset of symptoms: time lapse was significantly longer in children breast fed for a longer time (p < 0.001). On the contrary, age at first gluten ingestion seemed to have no influence on age at onset, since it was similar in both groups.
