SARS-CoV-2 Antibodies in Children with Chronic Disease from a Pediatric Gastroenterology Outpatient Clinic.

Purpose: At the beginning of the Coronavirus disease (COVID-19) epidemic, physicians paid close attention to children with chronic diseases to prevent transmission or a severe course of infection. We aimed to measure the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody levels in children with chronic gastrointestinal and liver diseases to analyze the risk factors for infection and its interaction with their primary disease.

Methods: This cross-sectional study analyzed SARS-CoV-2 antibody levels in patients with gastrointestinal and liver diseases (n=141) and in healthy children (n=48) between January and February 2021.

New-onset celiac disease in children during COVID-19 pandemic.

Aim: We aimed to analyse the influence of the COVID-19 pandemic on the frequency and clinical presentation of celiac disease.

Methods: The study included the patients with celiac disease since January 2008. They were divided into 2 groups (diagnosed in pre-pandemic [January 2008 and February 2020] [n = 148] and in pandemic period [March 2020 and June 2021] [n = 47]).

Early onset congenital diarrheas; single center experience.

Background: Congenital diarrheal disorders (CDDs) are a rare group of enteropathies that typically present in the early few months of life and pose a diagnostic challenge. We aimed to analyze the clinical findings and outcome of infants with CDDs and share experience about genetic testing.

Methods: Demographic, clinical and genetic findings, and outcome of the patients (n = 24) with CDDs were recorded from hospital files.
