Previous studies demonstrated that during cisplatin-induced acute renal failure, there is a significant reduction in proximal tubule fatty acid oxidation. We now report on the effects of peroxisome proliferator-activated receptor-alpha (PPAR alpha) ligand Wy-14643 (WY) on the abnormalities of medium chain fatty acid oxidation and pyruvate dehydrogenase complex (PDC) activity in kidney tissue of cisplatin-treated mice. Cisplatin causes a significant reduction in mRNA levels and enzyme activity of mitochondrial medium chain acyl-CoA dehydrogenase (MCAD). PPAR alpha ligand WY ameliorated cisplatin-induced acute renal failure and prevented cisplatin-induced reduction of mRNA levels and enzyme activity of MCAD. In contrast, in cisplatin-treated PPAR alpha null mice, WY did not protect kidney function and did not reverse cisplatin-induced decreased expression of MCAD. Cisplatin inhibited renal PDC activity before the development of acute tubular necrosis, and PDC inhibition was reversed by pretreatment with PPAR alpha agonist WY. Cisplatin also induced increased mRNA and protein levels of pyruvate dehydrogenase kinase-4 (PDK4), and PPAR alpha ligand WY prevented cisplatin-induced increased expression of PDK4 protein levels in wild-type mice. We conclude that PPAR alpha agonists have therapeutic potential for cisplatin-induced acute renal failure. Use of PPAR alpha ligands prevents acute tubular necrosis by ameliorating cisplatin-induced inhibition of two distinct metabolic processes, MCAD-mediated fatty acid oxidation and PDC activity.

We report an adult case of late-onset riboflavin-responsive multiple acyl-CoA dehydrogenase deficiency (MADD) characterized by episodic recurrent rhabdomyolysis and acute renal failure after the age of 46. Muscle biopsy revealed lipid storage myopathy and the finding of serum acylcarnitine and urine organic acid analyses were consistent with MADD. A compound heterozygous mutation was identified in the electron-transferring-flavoprotein dehydrogenase (ETFDH) gene, including a novel missense mutation, which confirmed the diagnosis of MADD. After administration of riboflavin and L-carnitine, the muscle weakness and fatigability gradually improved. Acylcarnitine and urine organic acid were also normalized after supplementation. Thus, MADD should be included in one of the differential diagnoses for adult recurrent rhabdomyolysis. Gene analysis is useful to confirm the diagnosis, and early diagnosis is important because riboflavin treatment has been effective in a significant number of patients with MADD.
