BACKGROUND/AIMS: Several dietary interventions, including those involving conjugated linoleic acid (CLA), slow progression of polycystic kidney disease (PKD) when initiated in the early stages of disease in Han:SPRD-cy rats. However, in humans, kidney disease is often undetected until extensive renal injury has developed. The objective of this study therefore was to determine whether initiating dietary CLA intervention in advanced PKD would slow disease progression.
METHODS: Adult male Han:SPRD-cy rats with advanced kidney disease were fed diets with or without 1% CLA for 16 weeks. Disease progression was assessed by serum urea, proteinuria, and creatinine clearance, and morphological and immunohistochemical measurements for pathologic change.
RESULTS: Renal injury was lower in the PKD rats given CLA compared to those given the control diet as indicated by a reduction in inflammation (42% less), fibrosis (28% less), oxidative damage (30% less) and proliferating cells (35% less). Diet had no effect on body, kidney, or liver weight, serum urea, serum creatinine, creatinine clearance, proteinuria, or cyst volume.
CONCLUSIONS: Late dietary intervention with CLA reduced some disease-associated pathologies, but did not alter renal function in adult Han:SPRD-cy rats. The long-term anti-inflammatory, antioxidant, and antiproliferative benefits of CLA in advanced kidney disease remain to be determined.
