"Geographical distribution of risk genotypes in pediatric patients with celiac disease in Spain".

Celiac disease is strongly associated with HLA DQ, specifically with haplotypes. DRB1*03-DQA1*05:01/DQB1*02:01 (DQ2.5),DRB1*07-DQA1*02:01/DQB1*02:02 (DQ2.

Correlation of Anti-Tissue Transglutaminase Antibodies With the Mucosal Changes and IgA Status of Children With Celiac Disease.

Objectives: The objective of this study was to assess the association between serological markers and changes of the intestinal mucosa in children with celiac disease (CD).

Methods: Clinical data from CD patients under 15 years old were collected from the participating centers in an on-line multicenter nationwide observational Spanish registry called REPAC-2 (2011-2017). Correlation between anti-tissue transglutaminase antibodies (t-TGA) levels and other variables, including mucosal damage and clinical findings (symptoms, age, and gender), was assessed.

Hypersensitivity reaction to hyaluronic acid dermal filler after COVID-19 vaccination: A series of cases in São Paulo, Brazil.

Brazil ranked second in the world for the number of aesthetic procedures carried out in 2019. Five case reports of delayed hypersensitivity reaction to hyaluronic acid dermal filler after COVID-19 vaccination are presented in this paper. Additional vaccination for new variants, including omicron, will be necessary; therefore, aesthetic professionals should be aware of this possibility and advise patients accordingly.

Prospective longitudinal study: use of faecal gluten immunogenic peptides to monitor children diagnosed with coeliac disease during transition to a gluten-free diet.

Background: Treatment for coeliac disease is a lifelong strict gluten-free diet. Although guidelines recommend regular follow-up with dietary interviews and coeliac serology, these methods may be inaccurate.

Aim: To evaluate the usefulness of faecal gluten immunogenic peptides to support the diagnosis and to determine the adherence to the gluten-free diet in coeliac children.
