In inflammatory diarrhea due to eosinophilic gastroenteritis, which cell type is elevated?

• A. Eosinophils
• B. Lymphocytes
• C. Neutrophils
• D. Platelets

Answer: (A)

Eosinophils are elevated in eosinophilic gastroenteritis because this condition is driven by eosinophilic inflammation of the GI tract. Eosinophils are recruited in allergic-type responses and parasitic processes, and their activation within the mucosa leads to inflammation and symptoms like diarrhea. Neutrophils would point to an acute bacterial process, lymphocytes to certain chronic viral or immune conditions, and platelets may rise with general inflammation but do not specifically reflect this eosinophilic process.
