Insights
Excessive cow milk intake can cause protein-losing enteropathy (PLE) and severe iron deficiency anemia (IDA) in toddlers. Restricting cow milk and iron supplementation effectively resolved edema and improved anemia in all patients.
Area of Science:
- Pediatrics
- Gastroenterology
- Hematology
Background:
- Protein-losing enteropathy (PLE) is rarely associated with severe iron deficiency anemia (IDA) and excessive cow milk intake.
- This condition often presents with edema in toddlers.
Purpose of the Study:
- To describe a series of toddlers with PLE, IDA, and edema linked to high cow milk consumption.
- To highlight the diagnostic and therapeutic considerations for this uncommonly recognized phenomenon.
Main Methods:
- Retrospective case series of 7 toddlers evaluated between November 2016 and January 2019.
- Laboratory studies confirmed IDA, hypoalbuminemia, and PLE.
- Treatment involved cow milk restriction and oral iron supplementation.
Main Results:
- All 7 toddlers presented with edema, IDA, and hypoalbuminemia.
- Following cow milk restriction and iron supplementation, all patients showed resolution of edema and improvement in IDA.
- Individual diagnostic evaluations and treatments varied.
Conclusions:
- Cow milk-induced PLE and IDA should be considered in toddlers presenting with anasarca (generalized edema).
- Dietary modification (cow milk restriction) and iron supplementation are effective treatments.
Abstract:
Protein-losing enteropathy (PLE) in the setting of severe iron deficiency anemia (IDA) and excessive cow milk intake is an uncommonly recognized phenomenon. Here, we describe a series of 7 toddlers who presented for evaluation of edema in the setting of excessive cow milk intake between November 2016 and January 2019. Laboratory studies in each patient were consistent with IDA and hypoalbuminemia with evidence of PLE. Diagnostic evaluation and treatment of each patient differed, although all were instructed to restrict cow milk and provided with oral iron supplementation. The edema had resolved, and the IDA had improved in all 7 patients by the time of their follow-up outpatient appointments. Iron deficiency and PLE should be considered in patients who present with anasarca.
