Natural remission of nephrotic syndrome in a dog with immune-complex glomerular disease.
A nephrotic syndrome caused by immune-complex glomerular disease was diagnosed in a 4-year-old male Great Dane. The syndrome was characterized by proteinuria, hypoproteinemia, hypoalbuminemia, hypercholesterolemia, and subcutaneous edema. Renal biopsy revealed segmental membranous glomerular disease. The edema underwent complete remission 18 days after admission. Two months after admission, there was no clinical or laboratory evidence of glomerular disease. Periodic reevaluation of the dog during the next 2 years revealed recurrence of proteinuria, but no other clinical or laboratory abnormalities. Serial renal biopsies revealed persistence, but no appreciable increase, in the severity of the segmental membranous glomerular disease. The natural course of the nephrotic syndrome and immune-complex glomerular disease has been associated with unpredictable variability. It was concluded that the widespread use of corticosteroid or immunosuppressant therapy in dogs with immune complex glomerular disease should be withheld until the natural course of the disease has been evaluated in a significant number of patients and until the results of well-controlled clinical studies confirm or deny their therapeutic value.
