About This Practice

According to its website, Columbia Allergy's Fremont office is the practice's A-ILIT and oral immunotherapy (OIT) treatment center, with more offices in Oregon and Washington. Dr. Sanjeev Jain and Melissa Hutton, PA-C, see patients in Fremont. The practice lists precision allergy testing for environmental, food and medication triggers, asthma care with action plans and biologic therapies, and immunotherapy through allergy shots or sublingual drops. Columbia Allergy calls its version of intralymphatic immunotherapy (ILIT) A-ILIT. Three ultrasound guided injections are given at the start, four weeks later and eight weeks later. Standard ILIT uses lymph nodes in the groin, while A-ILIT uses lymph nodes in the neck, which the practice describes as directly connected to nasal and airway immunity. Columbia Allergy says several allergens can be treated in one course, including tree, grass and weed pollen, dust mites, pet dander and mold, and that an experienced radiologist performs the injections.
