High prevalence of silent celiac disease in preschool children screened with IgA/IgG antiendomysium antibodies.

Background: Because of the different sensitivity and specificity of serologic tests, the search for silent celiac disease is usually performed with the combined or sequential use of several tests. Among these, the IgA-class endomysium antibody test has the highest specificity and positive predictive value, but it may overlook IgA-deficient patients.

Methods: To test a new one-step screening approach, serum samples from 427 apparently healthy, 3- to 6-year-old Hungarian children were investigated for IgA-class and IgG-class endomysium antibodies using monkey esophagus and human jejunum as substrates.

Families with multiple cases of gluten-sensitive enteropathy.

Unlabelled: Early detection of oligosymptomatic gluten-sensitive enteropathy (GSE) may contribute to the prevention of late complications, such as malignancy. Family members of known GSE patients are at higher risk of being affected. To evaluate the frequency and clinical significance of multiple occurrence, we routinely offered an antiendomysium antibody (EmA)-based non-invasive screening to affected families.

Prospective significance of antiendomysium antibody positivity in subsequently verified celiac disease.

Background: In order to assess their long-term predictability for the diagnosis of celiac disease, antiendomysium antibody results were compared with the outcome of the Interlaken diagnostic process.

Methods: Prospective gluten challenge was performed in 153 children with previously diagnosed flat small-intestine mucosa. In 90 patients (Group A), endomysium antibodies were initially positive, in seven (Group B) they were negative, and 56 patients (Group C) had no initial serological results.

Intrascrotal and testicular solid masses in childhood.

A retrospective study was performed between 1985 and 1994 on paediatric patients operated for asymptomatic intrascrotal or testicular palpable masses. Tumour was suspected in each case and it was surgically explored. Twenty-six children were affected, their age ranging between 9 days and 14 years.
