We evaluated the reliability of IgA and IgG antigliadin antibodies (AGA-A, AGA-G), antireticulin antibody (ARA), endomysial antibodies (EmA), and alpha 1-antitrypsin clearance (alpha 1-AT CL) in the detection of celiac sprue (CS) in 59 first-degree asymptomatic relatives of celiac patients who had duodenal biopsy. Twenty-four relatives who had normal(More)
The present study aims to evaluate the usefulness of combined pulse Doppler-real-time ultrasonography as a noninvasive method for the measurement of portal blood flow in man. This measurement technique was performed on 12 healthy subjects and 20 patients with portal hypertension. Ten patients (group 1) were evaluated prior to and after ingestion of a(More)
OBJECTIVES This prospective study was designed to assess the nutritional changes associated with the long-term treatment of celiac disease. In addition, we analyzed whether these changes were related to the degree of compliance with a gluten-free diet. METHODS We studied nutritional parameters and body composition in 25 newly diagnosed celiac patients(More)
INTRODUCTION Dyspepsia is a word that means bad digestion. In the conviction of which it is a question of an entity that it includes different disciplines, we realize a meeting consensus to discuss and to resolve a diagnostic and therapeutic algorithm of national order. OBJECTIVE To agree on a national algorithm applicable to the functional dyspepsia. (More)
Motility disorders of the digestive tract have long been implicated in the pathophysiology of diarrhea in patients with celiac sprue. However, the contribution of the colon to the intestinal transit of celiac sprue has not been reported. Our aim was to determine whether sprue alters gut transit and whether differences in the clinical status of the disease(More)
Let G be a noncompact semisimple Lie group and Γ an arbitrary discrete, torsion-free subgroup of G. Let λ 0 (M) be the bottom of the spectrum of the Laplace-Beltrami operator on the locally symmetric space M = Γ\X, and let δ(Γ) be the exponent of growth of Γ. If G has rank 1, then these quantities are related by a well-known formula due to Elstrodt,(More)
