Eosinophilic gastrointestinal (GI) disease (EGID) beyond eosinophilic esophagitis is not commonly reported in the developing world.
To estimate the prevalence of EGID in a selected group of pediatric patients suffering from non-functional chronic abdominal pain (CAP).
A retrospective analysis was conducted on case records of children with CAP. Those exhibiting clinical or laboratory alarming features underwent endoscopic evaluation. Histopathology reports from upper GI endoscopy and ileo-colonoscopy determined the diagnosis of EGID. Subsequent analyses included clinical presentations, presence of atopy in the children or family, hemoglobin, albumin, serum immunoglobulin E (IgE), fecal calprotectin levels, endoscopic appearances, treatment methods, and outcomes.
A total of 368 children with organic CAP were subjected to endoscopic evaluation. Among them, 19 (5.2%) patients with CAP were diagnosed with EGID. The median age of the children was 11.1 years (interquartile range = 8.4-14.4). The estimated prevalence of EGID in children with organic CAP was 520/10000 children over 5 years. Periumbilical pain was the most common site (63%). Family history of atopy, peripheral blood eosinophilia, and elevated serum IgE were the three parameters significantly associated with EGID. Clinical remission was obtained in all children at 6 months. The 47% had microscopic remission and maintained remission until a 1-year follow-up. The 53% had a fluctuating clinical course after 6 months.
EGID beyond the esophagus is not an uncommon entity among the children of India. It can contribute significantly to the etiology of pediatric CAP.
Core Tip: Eosinophilic gastrointestinal disease (EGID) is often an underdiagnosed cause of chronic abdominal pain (CAP) in children. This study estimated how frequently EGID is responsible for the significant pain some of these children experience. This study is unique because although abdominal pain is the most common symptom of EGID, its prevalence in CAP cases has rarely been explored. Additionally, this study uncovered key features of EGID, such as clinical and endoscopic findings, fecal calprotectin levels, presence or absence of atopy, serum immunoglobulin E levels, and response to treatment. These findings contribute valuable insights to the growing knowledge of EGID in children.
