Abstract:
A 3-year-old boy developed transient protein-losing gastroenteropathy associated with cytomegalovirus (CMV) infection. Both IgG and IgM antibodies to CMV were positive in a serologic blood test. Upper gastrointestinal endoscopy showed multiple erosions throughout the body of the stomach, without enlarged gastric folds. Histological examination of the biopsy specimens indicated eosinophilic gastroenteritis and CMV infection. The patient had complete resolution without specific therapy for CMV in four weeks. An allergic reaction as well as CMV infection played important roles in the pathogenesis of this case.

Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Immunology
Background:
- Protein-losing gastroenteropathy (PLG) is a rare condition characterized by excessive loss of serum proteins into the gastrointestinal tract.
- Cytomegalovirus (CMV) infection is common in children and can cause a range of clinical manifestations.
- Eosinophilic gastroenteritis is an allergic disorder involving eosinophilic infiltration of the gastrointestinal tract.
Observation:
- A 3-year-old boy presented with symptoms suggestive of protein-losing gastroenteropathy.
- Serologic tests confirmed active cytomegalovirus (CMV) infection.
- Endoscopic examination revealed gastric erosions, and biopsies showed eosinophilic gastroenteritis and CMV infection.
Findings:
- The patient experienced transient protein-losing gastroenteropathy.
- Complete resolution occurred within four weeks without specific anti-CMV therapy.
- Both CMV infection and an allergic reaction were implicated in the disease's development.
Implications:
- This case highlights a potential association between cytomegalovirus (CMV) infection and eosinophilic gastroenteritis presenting as protein-losing gastroenteropathy in a pediatric patient.
- The findings suggest that CMV infection can trigger or exacerbate allergic gastrointestinal conditions.
- Complete recovery without specific antiviral treatment underscores the self-limiting nature of this presentation in immunocompetent children.
