abstract = {Our study evaluated the effect of creatine and homoarginine
in AGAT- and GAMT-deficient mice after simvastatin exposure.
Balestrino and Adriano suggest that guanidinoacetate might
explain the difference between AGAT- and GAMT-deficient mice
in simvastatin-induced myopathy. We agree with Balestrino
and Adriano that our data shows that (1) creatine possesses
a protective potential to ameliorate statin-induced myopathy
in humans and mice and (2) homoarginine did not reveal a
beneficial effect in statin-induced myopathy. Third, we
agree that guanidinoacetate can be phosphorylated and
partially compensate for phosphocreatine. In our study,
simvastatin-induced damage showed a trend to be less
pronounced in GAMT-deficient mice compared with wildtype
mice. Therefore, (phospo) guanidinoacetate cannot completely
explain the milder phenotype of GAMT-deficient mice, but we
agree that it might contribute to ameliorate statin-induced
myopathy in GAMT-deficient mice compared with AGAT-deficient
mice. Finally, we agree with Balestino and Adriano that AGAT
metabolites should further be evaluated as potential
treatments in statin-induced myopathy.},
