Pediatric hypertrophic gastropathy
Insights
Four children developed severe hypoproteinemia and stomach abnormalities. Cytomegalovirus (CMV) was detected in all cases, suggesting a potential link between this viral infection and the children's gastrointestinal symptoms.
Area of Science:
- Pediatric Gastroenterology
- Infectious Diseases
- Virology
Background:
- Hypoproteinemia in children can have various causes, including liver disease, malnutrition, and kidney issues.
- Gastrointestinal manifestations of viral infections can be diverse and sometimes present atypically.
Purpose of the Study:
- To describe a series of four pediatric cases with unexplained hypoproteinemia and gastric abnormalities.
- To investigate the potential role of cytomegalovirus (CMV) in the observed clinical presentation.
Main Methods:
- Case series review of four previously healthy children presenting within a 6-week period.
- Clinical evaluation including assessment for liver disease, malnutrition, and proteinuria.
- Radiographic imaging of the stomach.
- Laboratory investigations including viral cultures (CMV) from urine and gastric biopsies.
- Histopathological examination of gastric biopsy specimens for viral inclusions.
Main Results:
- All four children presented with marked hypoproteinemia, without evidence of liver disease, malnutrition, or significant proteinuria.
- Strikingly similar radiographic findings showed enlarged gastric folds in the fundus and body.
- Prodromal symptoms suggestive of viral illness were noted in three children.
- Cytomegalovirus (CMV) was isolated from urine in all four patients and from gastric biopsies in three.
- Gastric biopsy specimens from two patients revealed intranuclear inclusions consistent with CMV.
Conclusions:
- A cluster of pediatric cases with hypoproteinemia and characteristic gastric findings was observed.
- Cytomegalovirus (CMV) was frequently detected in these patients, implicating it as a potential causative agent.
- Further research is needed to definitively establish the causal relationship between CMV infection and this specific clinical syndrome in children.
Abstract:
Four previously healthy children presented in a 6-week period with marked hypoproteinemia without liver disease, malnutrition, or significant proteinuria. They all had strikingly similar radiographic findings consisting of enlarged folds confined to the fundus and body of the stomach. Three of the children had prodromal symptoms suggesting a viral illness. Cytomegalovirus was cultured from the urine in all cases and from the gastric biopsy specimens in three patients. Two of these patients also showed intranuclear inclusions in their biopsy specimens compatible with cytomegalovirus. It is not certain if cytomegalovirus was the cause of the illness.
