Remission of severe familial proteinuria in a Bracco Italiano dog.

The objective of this report was to document clinical remission of suspected familial proteinuria in a Bracco Italiano dog. A 4-year-old intact female Bracco Italiano with a familial history of amyloidosis was presented because of unilateral chemosis, polyuria, and polydipsia. Hypoalbuminemia and severe proteinuria were detected via initial diagnostics. Although no renal histopathologic assessment was done, there was a strong clinical suspicion for renal amyloidosis. The dog was treated with telmisartan and colchicine (in addition to other therapies) for proteinuria and achieved clinical remission > 5 y post-diagnosis. Key clinical message: Telmisartan is an appropriate 1st-line therapy for proteinuric dogs. Favorable long-term outcomes are possible for dogs with severe proteinuria. Prospective studies are warranted to evaluate effects of telmisartan on AA amyloidogenesis.
