Input: No trials were included in the review. There are no published or ongoing randomised controlled clinical trials relevant to this review question. Therefore, in the absence of any high level evidence, clinicians should base their decisions on clinical experience and in conjunction with preferences of the individual where appropriate. This does not mean that carnitine is ineffective or should not be used in any inborn error of metabolism. However, given the lack of evidence both on the effectiveness and safety of carnitine and on the necessary dose and frequency to be prescribed, the current prescribing practice should continue to be observed and monitored with care until further evidence is available. Methodologically sound trials, reported according to the Consolidated Standards of Reporting Trials (CONSORT) statement, are required. It should be considered whether placebo-controlled trials in potentially lethal diseases, e.g. carnitine transporter disorder or glutaric aciduria type I, are ethical.
Output:

Unfortunately, we did not find any good quality trials to include in the review. This does not mean that carnitine is ineffective or should not be used in treating inborn errors of metabolism; however, individuals receiving carnitine should be carefully observed and monitored. Therefore, we recommend that clinicians base their decision to prescribe carnitine on clinical experience together with individual preferences. Future trials should include patient-reported outcomes using validated and internationally recognised scales. Any adverse events associated with the treatment should be reported. It should be carefully considered whether placebo-controlled trials in potentially lethal diseases, e.g. carnitine transporter disorder or glutaric aciduria type I, are ethical.
