The Golden Retriever Muscular Dystrophy (GRMD) is genetically homologous to Duchenne muscular dystrophy (DMD) that affects humans. It is a genetic disease that causes progressive degeneration of skeletal muscle. Considering the intense muscle changes, it is natural to think in possible kidney damage caused by intense muscle injury. We evaluated six male Golden Retriever dogs affected by Duchenne muscular dystrophy (GRMD) and three clinically healthy male dogs. The urinary proteins and creatinine concentration were determined. The proteins were analyzed by polyacrylamide gel electrophoresis. The results showed that pathological proteinuria is not directly associated with Duchenne muscular dystrophy, but several parameters showed increased concentrations for affected animals, as the ratio protein/albumin, which was higher in dystrophic dogs, probably a consequence of microalbuminuria a sign of early kidney damage. These results aim to base future studies and clinical evaluations considering the pathologies arising from or associated with this genetic disease. |
