Celiac disease (CD) is a rare example of multifactorial disorder in which a genetic test is of great clinical relevance, as the disease rarely develops in the absence of specific HLA alleles. We typed DR-DQ genes in 437 Italian children with celiac disease, 834 first-degree relatives, and 551 controls. Of patients, 91% carried DQ2 and/or DQ8 heterodimers,(More)
OBJECTIVE The high prevalence of celiac disease (CD) prompted us to evaluate a new, noninvasive disease screening strategy. The aim was to identify CD in 6- to 8-year-old children for a timely diagnosis, start gluten-free diet (GFD) in compliant subjects, achieve the growth target, and prevent CD complications. METHODS Five thousand subjects were invited(More)
OBJECTIVES Celiac disease (CD)-related lesions have been reported in duodenal bulb biopsies, sometimes the bulb mucosa being the only one affected. The aim was to verify in a significant series whether histological lesions are always present in the bulb of celiac patients, what is the prevalence of lesions when isolated to the bulb, and if similar lesions(More)
OBJECTIVES Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS Among 257 children evaluated for(More)
OBJECTIVES Patchy villous atrophy of the duodenal mucosa has been described in adults with untreated celiac disease (CD) but not in children. The authors evaluated the presence and the distribution of villous atrophy in children with celiac disease to see whether this histologic pattern exists in children. METHODS We studied 95 children at diagnosis(More)
OBJECTIVES The prevalence of celiac disease (CD) among the relatives and the complications of an undiagnosed CD prompted us to identify a useful disease screening strategy. METHODS We studied 441 first degree relatives of 208 CD patients by immunoglobulin (Ig)A antiendomysium antibodies (EMA) and radioimmunoprecipitation assay (RIA) IgA(More)
OBJECTIVE To test the possibility of detecting tissue transglutaminase autoantibodies (tTG-Abs) in saliva with a novel sensitive fluid-phase radioimmunoassay (RIA). STUDY DESIGN Paired saliva and serum samples from 39 patients with celiac disease (CD), at the first biopsy (Group 1: 28 females, mean age 11.5 +/- 11.1 years); 32 controls with a normal(More)
BACKGROUND Serum radioimmunoassay (RIA) tissue transglutaminase autoantibodies (tTG-Abs) proved to be a sensitive test also during coeliac disease (CD) follow-up. We demonstrated that RIA tTG-Abs could be detected in human saliva. AIM To evaluate salivary RIA tTG-Abs in coeliac children on gluten-free diet (GFD). METHODS Saliva and serum samples from(More)
BACKGROUND Celiac disease (CD) is a complex disorder triggered by gluten affecting genetically predisposed individuals. More than 90% of patients carry human lymphocyte antigen (HLA)-DQ2 (DQA1*05, DQB1*02) and/or HLA-DQ8 (DQA1*03, DQB1*0302). We propose the use of the DQ-CD Typing kit that allows identification of the HLA class II alleles(More)
OBJECTIVE Celiac disease (CD) has a prevalence of 0.55% to 1% in Italy. Identifying CD in schoolchildren to characterize CD iceberg and evaluate the effect of diagnosis in screening-detected children. METHODS A total of 7377 5- to 8-year-old children were invited to participate. A total of 5733 salivary samples were collected and tested for(More)
