Certifect-associated Pemphigus Foliaceus-like Reactions
Our group recently reported that the topical application of an amitraz-metaflumizone flea and tick control product (Promeris Duo, Pfizer) triggered the rare development of autoimmune pemphigus foliaceus (PF) in dogs. Lesions first appeared at the site of application before developing at typical PF sites. With the recent anecdotes of similar reactions occurring at the site of another concentrated amitraz-containing product (Certifect, Merial), we are interested to study the immune reaction occurring during these reactions.
Study Design:
Prospective case series
Inclusion Criteria:
- Dog has received Certifect on the dorsum
- Crusted skin lesions developed at the site of Certifect application
- Skin biopsies were taken and confirmed that lesions resembled those of pemphigus foliaceus
Exclusion Criteria:
- Application of other topical at the site of crusted lesion development
Samples:
- Collect at least 5 ml of blood, spin serum and freeze until shipment
- Contact author for study questionnaire (tolivry@ncsu.edu)
- Complete study questionnaire and attach pathology report
