Proton Pump Inhibitor Management for Pediatric Patients with Alpha-Gal Allergy

Understanding Alpha-Gal Syndrome

Alpha-gal syndrome is a clinical diagnosis characterized by delayed allergic reactions to mammalian products, which can include medications containing mammalian-derived ingredients 1
The cornerstone of managing alpha-gal syndrome is eliminating alpha-gal from both diet and medications, avoiding all mammalian-derived products 1
Children with alpha-gal syndrome must avoid not only mammalian meat but also products made from mammals such as gelatin, which can be present in medication formulations 1

The American Gastroenterological Association recommends lansoprazole orally disintegrating tablet (ODT) as a first-line option for pediatric patients with alpha-gal allergy due to its mammalian-product-free formulation 2
The FDA approves omeprazole for children 2-16 years of age 2
Esomeprazole may be considered as a second-line option if lansoprazole is not tolerated or available 2

PPIs are more effective than H2-receptor antagonists for symptom relief and healing of erosive esophagitis in children 2, 3
PPIs should be administered twice daily for at least 8-12 weeks prior to assessment of histological response in conditions like eosinophilic esophagitis 4
Higher-potency PPIs are recommended, with rabeprazole and esomeprazole being more potent than omeprazole and pantoprazole 5

PPIs should be administered approximately 30 minutes before meals for optimal effect 2
For children with alpha-gal syndrome, always verify that the specific brand and formulation of PPI does not contain mammalian-derived inactive ingredients 1

Long-term use of PPIs may be associated with risks such as lower respiratory tract infections, particularly in infants 6
In a multicenter double-blind RCT, serious adverse events, particularly lower respiratory tract infections, occurred more frequently with lansoprazole than with placebo in infants 6
