Response: Eosinophilic Esophagitis (EoE) is a chronic inflammation of the esophagus that is driven by eosinophils. A common class of medications used for this condition are called Proton Pump Inhibitors, or PPIs, which block the production of gastric acid in the stomach. Currently only 30 to 60 percent of children with EoE respond well when treated with PPIs.
We hypothesized that genetic variants in the genes for CYP2C19 and STAT6 could plausibly be associated with response to PPI therapy for EoE.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We started our work in the adverse outcome of maternal caffeine intake during pregnancy about 15 years ago. Then, we found that prenatal caffeine intake could result in nonalcoholic fatty liver disease in the offspring. However, the underlying mechanism was unclear.
So, we start the current work, and found that hat maternal caffeine intake disrupts liver development before and after birth, which might be the trigger of the adult non-alcoholic fatty liver disease in the offspring rats. Moreover, we further found that the fetal programming of liver glucocorticoid – insulin like growth factor 1 axis, a new endocrine axis first reported by our team, might participate in such process.
